- the housing of the contact pin connector is at least partially, preferably completely, made of a liquid crystal polymer and / or of semi-aromatic polyamides.
- Liquid crystal polymers are also referred to by the abbreviation FKP, or in English with the term "liquid crystal polymer", which is abbreviated to LCP.
- Semi-aromatic polyamides are designated by the abbreviation PPA and / or as polyphthalamides.
- the proposed materials LCP and PPA have a higher temperature resistance than PBT.
- liquid crystal polymers generally have a lower inherent strength.
- liquid crystal polymers and semi-aromatic polyamides are more temperature-resistant than PBT (at least in general), but they can have a lower intrinsic strength or become more brittle. Because of this, these materials are not conventionally used for contact pin connectors. However, it has now been found that a contact pin connector can still be produced from the materials, which is designed as an SMD and / or THR component.

- the plug contact can also be designed as a contact pin.
- the plug-in contact is doubly secured, so to speak, by the at least two form-fitting elements, i.e. attached to at least two points on the housing.
- the plug contact is hereby fastened by means of the form-fitting elements to at least that part of the housing which is formed from liquid crystal polymer and / or from semi-aromatic polyamides.
- This double securing and / or fastening of the plug contact increases the stability of the connection between the plug contact and the housing. This is particularly advantageous with the materials used for the housing.
- everyone can Plug contacts of a plug connection are fastened to the housing by means of at least two form-locking elements, preferably by means of at least four form-locking elements, in particular also all of the plug-in contacts of the contact pin connector.
- the at least two form-locking elements with which the at least one plug contact is attached to the housing, each have different forms.
- the at least one plug contact is fastened to the housing by means of at least two differently designed form-locking elements.
- the form-fit elements differ not only in their alignment, but also in their specific form.
- a first form-fit element can be designed as an outwardly pointing latching lug, a second as an inwardly notched groove, which allows the engagement of a latching lug of the complementary counterpart.
- the different form-locking elements are not only designed essentially mirror images, but also differ in their actual shape, for example one locking lug can be made longer than the other, or one projection can be made larger than another.
- the different shape of the form-fit elements also reinforces the fastening of the plug-in contact to the housing, in particular if the material should have a certain brittleness and one of the form-fit elements alone does not provide sufficient fastening.
- At least one of the form-locking elements is designed as a latching lug.
- the locking lug is designed in such a way that it holds the plug contact on the housing, e.g. when the plug connector is removed.
- Latching lugs represent particularly advantageous and simple form-locking elements which can be implemented comparatively easily both on the housing and on the plug contact.
- the housing has at least one stiffening rib.
- the stiffening rib can be made from the same material as the housing itself.
- the stiffening rib can in particular be made in one piece the housing, for example as an integrated housing component.
- the stiffening rib can in particular be designed as an injection-molded part together with the housing.
- the stiffening rib can, for example, have an elongated shape and run at least partially along a surface of the housing.
- the stiffening rib can increase the intrinsic strength of the housing. This is particularly advantageous with the materials used for the housing.
- the wall thickness of the housing on the stiffening rib is at least twice as great as a wall thickness of the housing at a point on the housing at which no stiffening rib is formed.
- the wall thickness of the housing is at least doubled by the stiffening rib.
- the housing can have a customary and / or predetermined wall thickness.
- the stiffening rib can have a thickness which is essentially at least as great as this usual, predetermined wall thickness.
- the stiffening rib is formed at least along an entire side surface of the housing.
- the stiffening rib runs at least from a first end of the side surface over the entire side surface to a second end of the side surface, which is formed opposite the first end. This reinforces this side surface of the housing. By reinforcing this one side surface, the inherent strength of the housing can be increased overall. Further stiffening ribs can be formed on the side surface. Furthermore, the stiffening rib on the housing can also extend beyond the first and / or the second end, that is to say not end at this first and second end of the side surface.
- the stiffening rib is designed so that it completely surrounds the housing.
- the stiffening rib can be designed to be closed, for example, running through four side surfaces of an essentially cuboid contact pin connector. This self-contained form of the stiffening rib increases the rigidity of the housing particularly strongly.
- the contact pin plug can also have a shape other than a substantially cuboid contact pin plug.
- an at least partially round contact pin plug that is to say, for example, a cylindrical contact pin plug, can also be encompassed by an essentially ring-shaped stiffening rib.
- a contact pin plug with a flat side and a rounded opposite side can also be surrounded by at least one stiffening rib.
- the stiffening rib is designed to run along an edge of the housing.
- This can in particular be an end edge of the housing, e.g. an end edge on an open plug-in side of the housing.
- the open plug-in side of the housing is mechanically stressed by plugging in and / or unplugging connectors.
- the reinforcement of the housing by the stiffening rib at one end edge of the housing is particularly favorable in order to compensate for a low inherent rigidity and / or high brittleness of the housing material.
- the stiffening rib can in particular encircle the end edge in such a way that it completely encircles the housing along the end edge.
- the stiffening rib can, for example, encircle the housing on an outside, i.e. it can be placed on an outside of the housing. As a result, no additional space is required inside the housing and, if necessary, plug connectors to be plugged in and / or unplugged are provided with an unobstructed plug-in path.
- the stiffening rib can also be formed at least partially on an inside of the housing, in particular at points that are not intended for inserting a plug connector.
- the contact pins protrude from the housing by a length that is at most as large as the thickness of the printed circuit board.
- the contact pins are not long enough to attach the contact pin connector to the circuit board by means of through-hole assembly (THT). Rather, the contact pins are so short that the contact pin plug can only be connected to the circuit board provided for this purpose as a surface-mounted and / or THR component.
- the contact pins are designed in such a way that the contact pin plug can be attached to the circuit board by means of surface mounting and / or by means of through-hole reflow technology.
- the housing is made at least partially from liquid crystal polymer and / or from semiaromatic polyamides.
- the method is used in particular to produce a contact pin connector according to the aspect described above. For this reason, all statements made on the contact pin connector also apply to the method and vice versa.
- Figure 1A shows a perspective view of a contact pin connector 100.
- the contact pin connector 100 has a multi-part housing and is designed as a connection box.
- the contact pin connector is essentially cuboid and therefore has six side faces.
- One of these side surfaces is designed as an at least partially open plug-in side 103, on which at least one plug connector can be plugged into the contact pin plug 100. In this case, electrical contacts can be established between such a plug connector (not shown in the figures) and the contact pin plug 100.
- a side surface of the contact pin connector 100 that is adjacent to the plug-in side 103 is designed as a contact side 102.
- the contact side 102 is arranged as the bottom.
- a plurality of contact pins protrude from the contact pin connector 100 on the contact side 102.
- the contact pin connector 100 can be connected to a printed circuit board by means of these contact pins, in particular in a reflow soft soldering process, for example by means of SMT and / or THR technology.
- the side surface of the contact pin connector 100 which is arranged opposite the plug-in side 103, is designed as an opposite side 104.
- the housing of the contact pin connector 100 has a protective cap 130 which is plugged onto the opposite side 104 of the contact pin connector 100 in such a way that the protective cap 130 covers a circuit board 160 formed on this opposite side 104.
- Figure 1B shows the contact pin plug 100 without the protective cap 130 as a capless contact pin plug 101.
- the capless contact pin plug 101 has all the components that are also used in the in Figure 1A has contact pin connector 100 shown, but without the protective cap 130.
- the protective cap 130 can be formed as part of the housing of the contact pin connector.
- the housing of the contact pin connector 100 also has a housing element 110. This housing element 110 is designed to be open on the plug-in side 103.
- the contact pin connector 100 can have a multi-part housing that, for example, comprises the housing element 110 and the protective cap 130, in particular consists of these.
- FIG. 1C shows a perspective illustration of the housing element 110 without the remaining elements of the contact pin connector 100
- Figures 1A, 1B and 1C are shown from the same perspective.
- the housing element 110 On the plug-in side 103, the housing element 110 has a stiffening rib 112.
- This stiffening rib 112 is designed as a thickening of that end edge which is formed on the plug-in side 103.
- the stiffening rib 112 runs around the housing element 110 completely along the edge, that is to say along the end edge which is formed directly on the plug-in side 103.
- the stiffening rib 112 is self-contained.
- the stiffening rib 112 is formed on the outwardly facing side surface of the housing element 110 and at least doubles the wall thickness of the housing element 110. In one exemplary embodiment, the stiffening rib 112 could also be made wider than an average wall thickness of the housing, in particular of the housing element 110.
- the stiffening rib 112 increases the stability of the housing element 110, and thus also the stability of the housing of the contact pin connector 100 as a whole. This enables the use of materials for the housing element 110 which have a lower inherent rigidity than, for example, PBT.
- the housing element 110 can be formed from LCP or from a PPA, for example, in particular made of PA9T and / or PA10T. These materials have a higher temperature resistance than PBT, which is why the housing element 110 can also be introduced into a corresponding heating furnace as part of a soft soldering process, such as a reflow process, without being deformed too much in the process. Such soft soldering processes are used in SMT and / or THR technology.
- the contact pin connector 100 is designed as a surface-mounted component, also called an SMD (surface mounted device), and / or as a THR component, that is to say as a through-hole reflow technology component.
- SMD surface mounted device
- THR through-hole reflow technology component
- the circuit board 160 is arranged in such a way that it closes off the capless contact pin connector 101 and / or essentially forms the opposite side 104.
- the circuit board 160 is dimensioned here essentially as large as the opposite side 104 of the contact pin connector 100.
- the circuit board 160 can be designed as a printed circuit board, e.g. as a PCB. Different electrical contacts of the contact pin connector 100 can be electrically contacted with one another on the circuit board, e.g. contact pins protruding from the contact side 102 and / or plug contacts of the contact pin connector 100, to which reference is made below.
- the housing element 110 can have one or more knobs 111 which protrude outwardly from the housing element 110 on at least one side surface, for example on the side surface of the contact pin connector 100 opposite the contact side 102.
- the knobs 111 can serve as a guide and / or as a form-fit element for attaching the protective cap 130 to the capless contact pin connector 101.
- the protective cap 130 can have complementary slots 131 for this purpose (cf. eg Figure 1A ), in which the knobs 111 engage when the protective cap 130 is attached to the contact pin connector 100.
- the protective cap 130 can also be formed from a liquid crystal polymer and / or a semi-aromatic polyamide, in particular from PA9T and / or PA10T.
- the protective cap 130 can also be made from PBT and can be removed when the contact pin connector is soldered.
- the protective cap 130 instead of the entire contact pin connector 100, only the capless contact pin connector 101 can be designed as a surface-mounted component and soldered to the circuit board. After the capless plug 101 has been soldered to the circuit board, which is not shown in the figures, the protective cap 130 can optionally be put back on.
- the protective cap 130 can therefore also be formed from PBT.
- Figure 2A shows a perspective view of the contact pin connector 100, in particular on the plug side 103.
- a plurality of contact pins 140 point out of the contact pin connector 100.
- These contact pins 140 are designed in such a way that they can be connected to a printed circuit board (not shown in the figures) by means of surface mounting and / or THR technology. Spacers such as pins and / or knobs can also be formed on the contact side 102.
- the contact pin connector 100 is designed to be essentially open.

Die Erfindung betrifft einen Kontaktpinstecker mit einem Gehäuse und einer Mehrzahl von Kontaktpins, welche an dem Gehäuse so ausgebildet und angeordnet sind, dass sie zum Kontaktieren und Verlöten mit einer Leiterplatte von dem Gehäuse abstehen.The invention relates to a contact pin connector with a housing and a plurality of contact pins which are designed and arranged on the housing in such a way that they protrude from the housing for contacting and soldering to a circuit board.
Dabei sind die Kontaktpins so ausgebildet, dass der Kontaktpinstecker mittels Oberflächenmontage und/oder mittels Through-Hole-Reflow Technologie an der Leiterplatte befestigbar ist. Weiterhin ist das Gehäuse zumindest teilweise aus Flüssigkristallpolymer und/oder aus semi-aromatischen Polyamiden ausgebildet.The contact pins are designed in such a way that the contact pin plug can be attached to the circuit board by means of surface mounting and / or by means of through-hole reflow technology. Furthermore, the housing is made at least partially from liquid crystal polymer and / or from semi-aromatic polyamides.
Mit anderen Worten ist der Kontaktpinsstecker dazu geeignet, ausgebildet und/oder vorgesehen, mittels eines Reflow-Weichlötverfahrens an der Leiterplatte befestigt zu werden.In other words, the contact pin plug is suitable, designed and / or intended to be attached to the circuit board by means of a reflow soft soldering process.
Der Kontaktpinstecker kann als Anschlusskasten ausgebildet sein. Nach der Erfindung ist der Kontaktpinstecker als MQS-Stecker ausgebildet. Die Kontaktpins sind als elektrische Kontaktpins ausgebildet und dienen zum elektrischen und mechanischen Kontaktieren der Leiterplatte, mit der sie verlötet werden können. Die Kontaktpins dienen insbesondere dazu, mit einer PCB-Leiterplatte verlötet zu werden, wobei PCB für "printed circuit board" steht. Da die Leiterplatte im Wesentlichen flächig ausgebildet ist, sind die Kontaktpins zumindest teilweise so ausgebildet, dass sie alle etwa parallel zu einer Kontaktrichtung ausgerichtet sind, in der sie von dem Kontaktpinstecker weg weisen und/oder abstehen. Dabei können die Kontaktpins zumindest teilweise im Wesentlichen parallel zueinander und parallel zur Kontaktrichtung ausgebildet sein. Der Kontaktpinstecker ist dazu ausgebildet und vorgesehen, in Kontaktrichtung zu der Leiterplatte hin bewegt zu werden, und zwar mit den aus dem Kontaktpinstecker herausragenden Kontaktpins zuerst. Die Kontaktpins können in physikalischem Kontakt mit der Leiterplatte mit dieser verlötet werden. Hierbei kann die Kontaktrichtung vom Kontaktpinstecker weg etwa im Lot auf eine dem Kontaktpinstecker zugewandte flächige Seite der Leiterplatte weisen.The contact pin plug can be designed as a connection box. According to the invention, the contact pin connector is designed as an MQS connector. The contact pins are designed as electrical contact pins and are used to make electrical and mechanical contact with the circuit board to which they can be soldered. The contact pins are used in particular to be soldered to a PCB circuit board, where PCB stands for “printed circuit board”. Since the circuit board is essentially flat, the contact pins are at least partially designed so that they are all aligned approximately parallel to a contact direction in which they point away from the contact pin connector and / or protrude. In this case, the contact pins can be formed at least partially essentially parallel to one another and parallel to the contact direction. The contact pin connector is designed and provided to be moved in the contact direction towards the circuit board, namely with the contact pins protruding from the contact pin connector first. The contact pins can be soldered to the circuit board in physical contact with the latter. Here, the contact direction away from the contact pin connector can point approximately perpendicular to a flat side of the circuit board facing the contact pin connector.
Der Kontaktpinstecker kann als "Mehrzahl von Kontaktpins" zumindest 10 Kontaktpins aufweisen, bevorzugt zumindest 20 Kontaktpins, besonders bevorzugt zumindest 40 Kontaktpins. Alle diese Kontaktpins weisen zumindest mit einem Ende aus dem Kontaktpinstecker heraus, insbesondere im Wesentlichen in Kontaktrichtung.As a “plurality of contact pins”, the contact pin plug can have at least 10 contact pins, preferably at least 20 contact pins, particularly preferably at least 40 contact pins. All of these contact pins have at least one end out of the contact pin connector, in particular essentially in the contact direction.
Die Kontaktpins sind derart ausgebildet, dass der Kontaktpinstecker durch eine Oberflächenmontage und/oder Through-Hole-Reflow-Technologie an der Leiterplatte befestigt werden kann. Hierbei kann insbesondere das Material der Kontaktpins, die Ausbildungsform, und/oder die Länge der Kontaktpins durch diese Eigenschaft der Kontaktpins bedingt sein.The contact pins are designed in such a way that the contact pin plug can be attached to the circuit board by surface mounting and / or through-hole reflow technology. In particular, the material of the contact pins, the design, and / or the length of the contact pins can be determined by this property of the contact pins.
Der Kontaktpinstecker selber kann als ein oberflächenmontiertes Bauelement ausgebildet, was auf Englisch mit dem Begriff "surface mount device" bezeichnet wird, was auch mit SMD abgekürzt wird. Der Kontaktpinstecker kann auch als ein THR-Bautelement ausgebildet sein, wobei THR als Abkürzung für Through-Hole-Reflow-Technologie steht.The contact pin connector itself can be designed as a surface-mounted component, which is referred to in English with the term "surface mount device", which is also abbreviated to SMD. The contact pin connector can also be designed as a THR component, with THR being the abbreviation for through-hole reflow technology.
Im Gegensatz zu herkömmlichen THT Kontaktpinsteckern ist der erfindungsgemäße Kontaktpinstecker als ein SMD- und/oder THR-Bauelement ausgebildet. Als solches SMD weist der Kontaktpinstecker keine langen Drahtanschlüsse auf, sondern lotfähige Anschlussflächen, die von den aus dem Gehäuse herausstehenden Kontaktpins bereitgestellt werden. Diese Art der Kontaktierung wird auch mit SMT bezeichnet, welches eine Abkürzung für den englischen Begriff "surface mounted technology" darstellt.In contrast to conventional THT contact pin connectors, the contact pin connector according to the invention is designed as an SMD and / or THR component. As such an SMD, the contact pin connector does not have long wire connections, but solderable connection surfaces that are provided by the contact pins protruding from the housing. This type of contact is also referred to as SMT, which is an abbreviation for the English term "surface mounted technology".
Mittels der THR-Technologie können Steckverbinder, die eigentlich nicht für die SMD-Bauweise geeignet sind, trotzdem dem Reflow-Lötverfahren zugänglich zu machen. In diesem Zusammenhang wurde die Through-Hole-Reflow-Technologie entwickelt. Dabei werden Through-hole-Bauelemente für die automatische Bestückung und die hohe thermische Belastung im Reflow-Ofen konstruiert. So lassen sich die Bestückungskosten für die automatische Leiterplattenbestückung senken, da einige Prozessschritte der normalen THT-Bestückung entfallen.Using THR technology, connectors that are actually not suitable for SMD construction can still be made accessible for reflow soldering. In this context, through-hole reflow technology was developed. Through-hole components are designed for automatic assembly and the high thermal load in the reflow oven. In this way, the assembly costs for the automatic circuit board assembly can be reduced, since some process steps of the normal THT assembly are omitted.
Bevorzugt ist der Kontaktpinstecker als ein THR-Bauelement ausgebildet.The contact pin connector is preferably designed as a THR component.
Die Kontaktierung zwischen dem Kontaktpinstecker und der Leiterplatte kann in einem Weichlötverfahren erfolgen, z.B. im sogenannten Reflow-Verfahren. Dabei wird das SMD- und/oder THR-Bauteil z.B. zusammen mit der Leiterplatte in einen Ofen eingebracht, in welchem das Bauteil mitsamt der Leiterplatte so erhitzt wird, dass die Lötverbindung hergestellt wird.The contact between the contact pin connector and the circuit board can be made in a soft soldering process, e.g. in the so-called reflow process. The SMD and / or THR component is placed in an oven together with the circuit board, for example, in which the component and the circuit board are heated so that the soldered connection is made.
Üblicherweise wird das Gehäuse von Kontaktpinsteckern aus PBT hergestellt, also aus Polybutylenterephthalat. Dieses Material ist jedoch nicht temperaturbeständig genug, um dem oben beschriebenen Weichlötverfahren in hinreichender Qualität standzuhalten.The housing of contact pin plugs is usually made from PBT, i.e. from polybutylene terephthalate. However, this material is not temperature-resistant enough to withstand the soft soldering process described above in sufficient quality.
Das Gehäuse des Kontaktpinsteckers ist zumindest teilweise, bevorzugt vollständig, aus einem Flüssigkristallpolymer und/oder aus semi-aromatischen Polyamiden hergestellt. Flüssigkristallpolymere werden auch mit der Abkürzung FKP bezeichnet, oder auf englisch mit dem Begriff "liquid crystal polymer", welcher mit LCP abgekürzt wird. Semi-aromatische Polyamide werden mit der Abkürzung PPA bezeichnet und/oder als Polyphthalamide. Die vorgeschlagenen Materialien LCP und PPA weisen eine höhere Temperaturbeständigkeit auf als PBT.The housing of the contact pin connector is at least partially, preferably completely, made of a liquid crystal polymer and / or of semi-aromatic polyamides. Liquid crystal polymers are also referred to by the abbreviation FKP, or in English with the term "liquid crystal polymer", which is abbreviated to LCP. Semi-aromatic polyamides are designated by the abbreviation PPA and / or as polyphthalamides. The proposed materials LCP and PPA have a higher temperature resistance than PBT.
Allerdings weisen dafür Flüssigkristallpolymere generell eine geringere Eigenfestigkeit auf. Mit anderen Worten sind Flüssigkristallpolymere und semi-aromatische Polyamide zwar temperaturbeständiger als PBT (zumindest im allgemeinen), jedoch können sie eine geringere Eigenfestigkeit aufweisen bzw. leichter spröde werden. Deswegen werden diese Materialien herkömmlich nicht für Kontaktpinstecker verwendet. Es hat sich nun allerdings herausgestellt, dass aus den Materialien dennoch ein Kontaktpinstecker hergestellt werden kann, welcher als SMD- und/oder THR-Bauteil ausgebildet ist.However, liquid crystal polymers generally have a lower inherent strength. In other words, liquid crystal polymers and semi-aromatic polyamides are more temperature-resistant than PBT (at least in general), but they can have a lower intrinsic strength or become more brittle. Because of this, these materials are not conventionally used for contact pin connectors. However, it has now been found that a contact pin connector can still be produced from the materials, which is designed as an SMD and / or THR component.
Dadurch wird ein Kontaktpinstecker ermöglicht, der als ein SMD- und/oder als ein THR-Bauteil ausgebildet ist und eine hinreichende Qualität aufweist. Hierbei kann das Gehäuse kostengünstig z.B. als Spritzgussbauteil ausgebildet werden.This enables a contact pin connector which is designed as an SMD and / or a THR component and is of sufficient quality. In this case, the housing can be designed inexpensively, for example, as an injection-molded component.
Das Gehäuse kann aus genau einem Material bestehen, also z.B. aus Flüssigkristallpolymer oder aus semi-aromatischen Polyamiden, oder aber aus einer Mischung dieser Materialien ausgebildet sein. Insbesondere kann das Gehäuse vollständig aus zumindest einem der genannten Materialien ausgebildet sein.The housing can consist of exactly one material, e.g. liquid crystal polymer or semi-aromatic polyamides, or a mixture of these materials. In particular, the housing can be formed entirely from at least one of the materials mentioned.
Gemäß einer Ausführungsform ist das Gehäuse zumindest zu 60%, bevorzugt zu zumindest 90%, aus Flüssigkristallpolymer und/oder semi-aromatischen Polyamiden ausgebildet. Die Prozentangaben betreffen hierbei Gewichtsprozentangaben bezüglich des Gehäusegewichts. Hierbei besteht das Gehäuse somit überwiegend aus zumindest einem der genannten Materialien, weswegen auch das mechanische Verhalten und/oder die Temperaturbeständigkeit des Gehäuses wesentlich von diesem Material abhängt.According to one embodiment, the housing is at least 60%, preferably at least 90%, made of liquid crystal polymer and / or semi-aromatic polyamides. The percentages relate to percentages by weight in relation to the weight of the housing. In this case, the housing consists predominantly of at least one of the materials mentioned, which is why the mechanical behavior and / or the temperature resistance of the housing also depends significantly on this material.
Gemäß einer Ausführungsform ist zumindest ein Gehäuseelement des Gehäuses zumindest zu 60%, bevorzugt zumindest zu 90%, besonders bevorzugt vollständig, aus Flüssigkristallpolymer und/oder semi-aromatischen Polyamiden ausgebildet. Die Prozentangaben betreffen wieder Gewichtsprozentangaben bezüglich des Gewichts des jeweiligen Gehäuseelements. In dieser Ausführungsform kann das Gehäuse mehrteilig ausgebildet sein. Hierbei ist zumindest das eine Gehäuseelement vorwiegend aus zumindest einem der genannten Materialien ausgebildet. Das Gehäuseelement ist als ein eigenständiges Bauteil des Gehäuses ausgebildet. Insbesondere können sämtliche Gehäuseelemente vorwiegend aus zumindest einem der genannten Materialien ausgebildet sein, welche(s) beim Weichlöten in den Lötofen eingebracht werden. Ggf. vorhandene Schutzkappen des Gehäuses können aus einem anderen (oder dem gleichen) Material ausgebildet sein und beim Weichlöten abgenommen werden. Hierbei können die Gehäuseelemente jeweils vorwiegend aus einem anderen der genannten Materialien ausgebildet sein, z.B. ein erstes Gehäuseelement aus einem ersten Flüssigkristallpolymer oder ersten semi-aromatischen Polyamid, ein zweites Gehäuseelement aus einem zweiten Flüssigkristallpolymer oder zweiten semi-aromatischen Polyamid usw. Auch kann ein erstes Gehäuseelement vorwiegend aus einem Flüssigkristallpolymer und ein zweites Gehäuseelement vorwiegend aus einem semi-aromatischen Polyamid ausgebildet sein. Hierbei können die Materialeigenschaften der genannten Materialien sinnvoll miteinander kombiniert werden.According to one embodiment, at least one housing element of the housing is at least 60%, preferably at least 90%, particularly preferably completely, made of liquid crystal polymer and / or semi-aromatic polyamides. The percentages again relate to percentages by weight with respect to the weight of the respective housing element. In this embodiment, the housing can be constructed in several parts. In this case, at least one housing element is predominantly formed from at least one of the materials mentioned. The housing element is designed as an independent component of the housing. In particular, all housing elements can predominantly be formed from at least one of the materials mentioned, which are introduced into the soldering furnace during soft soldering. Any protective caps on the housing that may be present can be made from a different (or the same) material and removed during soft soldering. Here, the housing elements can each predominantly be formed from a different of the materials mentioned, e.g. a first housing element made of a first liquid crystal polymer or first semi-aromatic polyamide, a second housing element made of a second liquid crystal polymer or second semi-aromatic polyamide, etc. A first housing element can also be used mainly composed of a liquid crystal polymer and a second housing element can be made predominantly from a semi-aromatic polyamide. Here, the material properties of the materials mentioned can be combined with one another in a meaningful way.
Gemäß einer Ausführungsform ist das Gehäuse zumindest teilweise aus Flüssigkristallpolymer, PA9T und/oder PA10T ausgebildet. Die Materialien PA9T (mit dem Handelsnamen PA9T-Faser Genestar) und PA10T (mit dem Handelsnamen: HT3:PA10T/X) zählen zu den semi-aromatischen Polyamiden. Dabei eignen sich insbesondere die Materialien PA9T und PA10T als Material für das Gehäuse.According to one embodiment, the housing is at least partially made of liquid crystal polymer, PA9T and / or PA10T. The materials PA9T (with the trade name PA9T Genestar fiber) and PA10T (with the trade name: HT3: PA10T / X) are among the semi-aromatic polyamides. The materials PA9T and PA10T are particularly suitable as the material for the housing.
Gemäß einer Ausführungsform weist der Kontaktpinstecker elektrische Steckkontakte auf, von welchen zumindest einer mittels zumindest zweier Formschlusselemente am Gehäuse befestigt ist. Die Steckkontakte sind als elektrische Steckkontakte ausgebildet. Die Steckkontakte können zur Kontaktierung mit einem Steckverbinder ausgebildet sein. Dabei können die Steckkontakte z.B. als männliche Steckkontakte ausgebildet sein, auf die ein zumindest teilweise weiblicher Steckverbinder aufgesteckt werden kann. Der zumindest eine Steckkontakt kann elektrisch mit zumindest einem der Kontaktpins verbunden sein. In einer Ausführungsform kann der Steckkontakt auch als ein Kontaktpin ausgebildet sein. Durch die Nutzung des Steckkontaktes beim Herstellen nicht nur einer elektrischen, sondern auch einer mechanischen Verbindung, mit einem Steckverbinder kann dieser Teil des Kontaktpinsteckers einer mechanischen Belastung standhalten. Da die für das Gehäuse verwendeten Materialien LCP und/oder PPA jedoch eine vergleichsweise geringe Eigenfestigkeit und/oder eine erhöhte Sprödigkeit aufweisen können, ist der Steckkontakt durch die zumindest zwei Formschlusselemente sozusagen doppelt gesichert, also an zumindest zwei Stellen am Gehäuse befestigt. Der Steckkontakt ist hiermit zumindest an dem Teil des Gehäuses mittels der Formschlusselemente befestigt, welches aus Flüssigkristallpolymer und/oder aus semi-aromatischen Polyamiden ausgebildet ist. Durch diese doppelte Sicherung und/oder Befestigung des Steckkontakts wird die Stabilität der Verbindung des Steckkontaktes mit dem Gehäuse erhöht. Dies ist gerade bei den für das Gehäuse verwendeten Materialien von Vorteil. Hierbei können insbesondere alle Steckkontakte einer Steckverbindung mittels zumindest zweier Formschlusselemente, bevorzugt mittels zumindest vier Formschlusselementen, an dem Gehäuse befestigt werden, insbesondere auch sämtliche Steckkontakte des Kontaktpinsteckers.According to one embodiment, the contact pin plug has electrical plug-in contacts, at least one of which is fastened to the housing by means of at least two form-fitting elements. The plug contacts are designed as electrical plug contacts. The plug contacts can be designed for contacting with a plug connector. The plug-in contacts can be designed, for example, as male plug-in contacts onto which an at least partially female connector can be plugged. The at least one plug contact can be electrically connected to at least one of the contact pins. In one embodiment, the plug contact can also be designed as a contact pin. By using the plug contact when establishing not only an electrical, but also a mechanical connection with a connector, this part of the contact pin connector can withstand mechanical stress. However, since the LCP and / or PPA materials used for the housing can have a comparatively low intrinsic strength and / or increased brittleness, the plug-in contact is doubly secured, so to speak, by the at least two form-fitting elements, i.e. attached to at least two points on the housing. The plug contact is hereby fastened by means of the form-fitting elements to at least that part of the housing which is formed from liquid crystal polymer and / or from semi-aromatic polyamides. This double securing and / or fastening of the plug contact increases the stability of the connection between the plug contact and the housing. This is particularly advantageous with the materials used for the housing. In particular, everyone can Plug contacts of a plug connection are fastened to the housing by means of at least two form-locking elements, preferably by means of at least four form-locking elements, in particular also all of the plug-in contacts of the contact pin connector.
In einer Weiterbildung dieser Ausführungsform weisen die zumindest zwei Formschlusselemente, mit denen der zumindest eine Steckkontakt am Gehäuse befestigt ist, jeweils unterschiedliche Ausbildungsformen auf. Mit anderen Worten ist der zumindest eine Steckkontakt mittels zumindest zweier unterschiedlich ausgebildeter Formschlusselemente am Gehäuse befestigt. Hierbei unterscheiden sich die Formschlusselemente nicht nur in ihrer Ausrichtung, sondern auch in ihrer konkreten Ausbildungsform. So kann z.B. ein erstes Formschlusselement als eine nach außen weisende Rastnase ausgebildet sein, ein zweites als eine nach innen eingekerbte Nut, welche den Eingriff einer Rastnase des komplementären Gegenstücks erlaubt. Hierbei sind die unterschiedlichen Formschlusselemente nicht nur im Wesentlichen spiegelbildlich ausgebildet, sondern unterscheiden sich in ihrer tatsächlichen Form, so kann z.B. eine Rastnase länger ausgebildet sein als die andere, oder ein Vorsprung größer als ein anderer ausgebildet sein. Auch die unterschiedliche Form der Formschlusselemente verstärkt die Befestigung des Steckkontaktes an dem Gehäuse, insbesondere falls das Material eine gewisse Sprödigkeit aufweisen sollte und eines der Formschlusselemente alleine keine hinreichende Befestigung bereitstellt.In a further development of this embodiment, the at least two form-locking elements, with which the at least one plug contact is attached to the housing, each have different forms. In other words, the at least one plug contact is fastened to the housing by means of at least two differently designed form-locking elements. The form-fit elements differ not only in their alignment, but also in their specific form. For example, a first form-fit element can be designed as an outwardly pointing latching lug, a second as an inwardly notched groove, which allows the engagement of a latching lug of the complementary counterpart. Here, the different form-locking elements are not only designed essentially mirror images, but also differ in their actual shape, for example one locking lug can be made longer than the other, or one projection can be made larger than another. The different shape of the form-fit elements also reinforces the fastening of the plug-in contact to the housing, in particular if the material should have a certain brittleness and one of the form-fit elements alone does not provide sufficient fastening.
Gemäß einer zusätzlichen oder alternativen Weiterbildung der Ausführungsform ist zumindest eines der Formschlusselemente als eine Rastnase ausgebildet. Die Rastnase ist hierbei so ausgebildet, dass sie den Steckkontakt z.B. bei einem Abziehen des Steckverbinders am Gehäuse festhält. Rastnasen stellen besonders vorteilhafte und einfache Formschlusselemente dar, welche sowohl am Gehäuse als auch am Steckkontakt vergleichsweise einfach realisiert werden können.According to an additional or alternative development of the embodiment, at least one of the form-locking elements is designed as a latching lug. The locking lug is designed in such a way that it holds the plug contact on the housing, e.g. when the plug connector is removed. Latching lugs represent particularly advantageous and simple form-locking elements which can be implemented comparatively easily both on the housing and on the plug contact.
Gemäß einer Ausführungsform weist das Gehäuse zumindest eine Versteifungsrippe auf. Hierbei kann die Versteifungsrippe aus demselben Material ausgebildet sein wie das Gehäuse selber. Die Versteifungsrippe kann hierbei insbesondere einteilig mit dem Gehäuse, also z.B. als ein integriertes Gehäusebauteil, ausgebildet sein. Die Versteifungsrippe kann insbesondere zusammen mit dem Gehäuse als ein Spritzgussteil ausgebildet sein. Die Versteifungsrippe kann z.B. eine längliche Form ausweisen und zumindest teilweise entlang einer Oberfläche des Gehäuses verlaufen. Durch die Versteifungsrippe kann die Eigenfestigkeit des Gehäuses erhöht werden. Dies ist insbesondere bei den für das Gehäuse verwendeten Materialien von Vorteil.According to one embodiment, the housing has at least one stiffening rib. Here, the stiffening rib can be made from the same material as the housing itself. The stiffening rib can in particular be made in one piece the housing, for example as an integrated housing component. The stiffening rib can in particular be designed as an injection-molded part together with the housing. The stiffening rib can, for example, have an elongated shape and run at least partially along a surface of the housing. The stiffening rib can increase the intrinsic strength of the housing. This is particularly advantageous with the materials used for the housing.
In einer Weiterbildung dieser Ausführungsform ist die Wandstärke des Gehäuses an der Versteifungsrippe zumindest doppelt so groß wie eine Wandstärke des Gehäuses an einer Stelle des Gehäuses, an dem keine Versteifungsrippe ausgebildet ist. Mit anderen Worten wird die Wandstärke des Gehäuses durch die Versteifungsrippe zumindest verdoppelt. An einer Stelle des Gehäuses, an dem keine Versteifungsrippe ausgebildet ist, kann das Gehäuse eine übliche und/oder vorbestimmte Wandstärke aufweisen. Die Versteifungsrippe kann eine Stärke aufweisen, die im Wesentlichen zumindest so groß ist wie diese übliche, vorbestimmte Wandstärke.In a further development of this embodiment, the wall thickness of the housing on the stiffening rib is at least twice as great as a wall thickness of the housing at a point on the housing at which no stiffening rib is formed. In other words, the wall thickness of the housing is at least doubled by the stiffening rib. At a point on the housing at which no stiffening rib is formed, the housing can have a customary and / or predetermined wall thickness. The stiffening rib can have a thickness which is essentially at least as great as this usual, predetermined wall thickness.
In einer zusätzlichen oder alternativen Weiterbildung der Ausführungsform ist die Versteifungsrippe zumindest entlang einer ganzen Seitenfläche des Gehäuses ausgebildet. Hierbei verläuft die Versteifungsrippe zumindest von einem ersten Ende der Seitenfläche über die ganze Seitenfläche hinweg bis zu einem zweiten Ende der Seitenfläche, welches dem ersten Ende gegenüberliegend ausgebildet ist. Dadurch wird diese Seitenfläche des Gehäuses verstärkt. Durch die Verstärkung dieser einen Seitenfläche kann die Eigenfestigkeit des Gehäuses insgesamt verstärkt werden. Auf der Seitenfläche können weitere Versteifungsrippen ausgebildet sein. Weiterhin kann die Versteifungsrippe am Gehäuse auch über das erste und/oder das zweite Ende hinaus weiterverlaufen, also nicht an diesem ersten und zweiten Ende der Seitenfläche enden.In an additional or alternative development of the embodiment, the stiffening rib is formed at least along an entire side surface of the housing. Here, the stiffening rib runs at least from a first end of the side surface over the entire side surface to a second end of the side surface, which is formed opposite the first end. This reinforces this side surface of the housing. By reinforcing this one side surface, the inherent strength of the housing can be increased overall. Further stiffening ribs can be formed on the side surface. Furthermore, the stiffening rib on the housing can also extend beyond the first and / or the second end, that is to say not end at this first and second end of the side surface.
Einer alternativen oder zusätzlichen Weiterbildung der Ausführungsform ist die Versteifungsrippe so ausgebildet, dass sie das Gehäuse vollständig umläuft. In dieser Weiterbildung kann die Versteifungsrippe in sich geschlossen ausgebildet sein, wobei sie z.B. vier Seitenflächen eines im Wesentlichen quaderförmigen Kontaktpinsteckers durchläuft. Diese in sich geschlossene Ausbildungsform der Versteifungsrippe erhöht die Steifigkeit des Gehäuses besonders stark. Der Kontaktpinstecker kann auch eine andere Form als ein im Wesentlichen quaderförmiger Kontaktpinstecker aufweisen. So kann ein zumindest teilweise runder Kontaktpinstecker, also z.B. ein zylinderförmiger Kontaktpinstecker, auch von einer im Wesentlichen ringförmigen Versteifungsrippe umlaufen werden. Ein Kontaktpinstecker mit einer flachen Seite und einer abgerundeten Gegenseite kann ebenfalls von zumindest einer Versteifungsrippe umlaufen werden.In an alternative or additional development of the embodiment, the stiffening rib is designed so that it completely surrounds the housing. In According to this further development, the stiffening rib can be designed to be closed, for example, running through four side surfaces of an essentially cuboid contact pin connector. This self-contained form of the stiffening rib increases the rigidity of the housing particularly strongly. The contact pin plug can also have a shape other than a substantially cuboid contact pin plug. Thus, an at least partially round contact pin plug, that is to say, for example, a cylindrical contact pin plug, can also be encompassed by an essentially ring-shaped stiffening rib. A contact pin plug with a flat side and a rounded opposite side can also be surrounded by at least one stiffening rib.
Gemäß einer alternativen oder zusätzlichen Weiterbildung der Ausführungsform ist die Versteifungsrippe entlang einer Kante des Gehäuses verlaufend ausgebildet. Hierbei kann es sich insbesondere um eine Endkante des Gehäuses handeln, z.B. eine Endkante an einer offenen Steckseite des Gehäuses. Insbesondere die offene Steckseite des Gehäuses ist mechanisch beansprucht durch das Ein- und/oder Ausstecken von Steckverbindern. Deswegen ist die Verstärkung des Gehäuses durch die Versteifungsrippe an einer Endkante des Gehäuses besonders günstig, um eine geringe Eigensteifigkeit und/oder hohe Sprödigkeit des Gehäusematerials auszugleichen. Die Versteifungsrippe kann insbesondere die Endkante so umlaufen, dass sie das Gehäuse vollständig entlang der Endkante umläuft.According to an alternative or additional development of the embodiment, the stiffening rib is designed to run along an edge of the housing. This can in particular be an end edge of the housing, e.g. an end edge on an open plug-in side of the housing. In particular, the open plug-in side of the housing is mechanically stressed by plugging in and / or unplugging connectors. For this reason, the reinforcement of the housing by the stiffening rib at one end edge of the housing is particularly favorable in order to compensate for a low inherent rigidity and / or high brittleness of the housing material. The stiffening rib can in particular encircle the end edge in such a way that it completely encircles the housing along the end edge.
Die Versteifungsrippe kann das Gehäuse z.B. an einer Außenseite umlaufen, also auf eine Außenseite des Gehäuses aufgesetzt sein. Dadurch wird im Inneren des Gehäuses kein zusätzlicher Platz benötigt und gegebenenfalls ein- und/oder auszusteckenden Steckverbindern ein hindernisfreier Steckweg bereitgestellet. Alternativ kann die Versteifungsrippe auch zumindest teilweise an einer Innenseite des Gehäuses ausgebildet sein, insbesondere an Stellen, die nicht zum Einstecken eines Steckverbinders vorgesehen sind.The stiffening rib can, for example, encircle the housing on an outside, i.e. it can be placed on an outside of the housing. As a result, no additional space is required inside the housing and, if necessary, plug connectors to be plugged in and / or unplugged are provided with an unobstructed plug-in path. Alternatively, the stiffening rib can also be formed at least partially on an inside of the housing, in particular at points that are not intended for inserting a plug connector.
Gemäß einer Ausführungsform stehen die Kontaktpins um eine Länge von dem Gehäuse ab, die maximal so groß ist wie die Dicke der Leiterplatte. Mit anderen Worten sind die Kontaktpins nicht lang genug ausgebildet, um dem Kontaktpinstecker mittels Durchsteckmontage (THT) an der Leiterplatte zu befestigen. Vielmehr sind die Kontaktpins so kurz ausgebildet, dass der Kontaktpinstecker nur als oberflächenmontiertes und/oder als THR-Bauteil mit der dazu vorgesehenen Leiterplatte verbindbar ist.According to one embodiment, the contact pins protrude from the housing by a length that is at most as large as the thickness of the printed circuit board. With others In other words, the contact pins are not long enough to attach the contact pin connector to the circuit board by means of through-hole assembly (THT). Rather, the contact pins are so short that the contact pin plug can only be connected to the circuit board provided for this purpose as a surface-mounted and / or THR component.
Die Erfindung betrifft auch ein Verfahren zum Herstellen eines SMD- und/oder THR-Kontaktpinsteckers mit den Schritten:
- Bereitstellen eines Gehäuses und
- Bereitstellen einer Mehrzahl von Kontaktpins, welche an dem Gehäuse so ausgebildet und angeordnet werden, dass sie zum Kontaktieren und Verlöten mit einer Leiterplatte von dem Gehäuse abstehen.
- Providing a housing and
- Providing a plurality of contact pins which are formed and arranged on the housing in such a way that they protrude from the housing for contacting and soldering to a circuit board.
Dabei werden die Kontaktpins so ausgebildet, dass der Kontaktpinstecker mittels Oberflächenmontage und/oder mittels Through-Hole-Reflow-Technologie an der Leiterplatte befestigbar ist. Weiterhin wird das Gehäuse zumindest teilweise aus Flüssigkristallpolymer und/oder aus semiaromatischen Polyamiden hergestellt.The contact pins are designed in such a way that the contact pin plug can be attached to the circuit board by means of surface mounting and / or by means of through-hole reflow technology. Furthermore, the housing is made at least partially from liquid crystal polymer and / or from semiaromatic polyamides.
Das Verfahren dient insbesondere zum Herstellen eines Kontaktpinsteckers gemäß dem voranstehend beschriebenen Aspekt. Deswegen betreffen alle zum Kontaktpinstecker getroffenen Ausführungen auch auf das Verfahren zu und umgekehrt.The method is used in particular to produce a contact pin connector according to the aspect described above. For this reason, all statements made on the contact pin connector also apply to the method and vice versa.

Die Seitenfläche des Kontaktpinsteckers 100, welche der Steckseite 103 gegenüberliegend angeordnet ist, ist als eine Gegenseite 104 ausgebildet. Das Gehäuse des Kontaktpinsteckers 100 weist eine Schutzkappe 130 auf, welche so auf die Gegenseite 104 des Kontaktpinsteckers 100 gesteckt ist, das die Schutzkappe 130 eine an dieser Gegenseite 104 ausgebildete Platine 160 überdeckt.The side surface of the
Der Kontaktpinstecker 100 kann ein mehrteiliges Gehäuse aufweisen, dass z.B das Gehäuseelement 110 und die Schutzkappe 130 umfasst, insbesondere aus diesen besteht.The
Durch die Versteifungsrippe 112 wird die Stabilität des Gehäuseelements 110 erhöht, und damit auch die Stabilität des Gehäuses des Kontaktpinsteckers 100 insgesamt. Dies ermöglicht die Verwendung von Materialien für das Gehäuseelement 110, die eine geringere Eigensteifigkeit als z.B. PBT aufweisen. Somit kann das Gehäuseelement 110 z.B. aus LCP oder aus einem PPA ausgebildet sein, insbesondere aus PA9T und/oder PA10T. Diese Materialien weisen eine höhere Temperaturbeständigkeit auf als PBT, weswegen das Gehäuseelement 110 auch im Rahmen eines Weichlötverfahrens wie z.B. eines Reflow-Verfahrens in einem entsprechenden Heizofen eingebracht werden kann, ohne sich hierbei zu stark zu verformen. Solche Weichlötprozesse werden in der SMT- und/oder in der THR-Technologie verwendet.The stiffening

An der Gegenseite 104 ist die Platine 160 so angeordnet, dass sie den kappenlosen Kontaktpinstecker 101 abschließt und/oder die Gegenseite 104 im Wesentlichen ausbildet. Die Platine 160 ist hierbei im Wesentlichen so groß dimensioniert wie die Gegenseite 104 des Kontaktpinsteckers 100. Die Platine 160 kann als Leiterplatte, z.B. als PCB ausgebildet sein. An der Platine können unterschiedliche elektrische Kontakte des Kontaktpinsteckers 100 miteinander elektrisch kontaktiert sein, z.B. an der Kontaktseite 102 herausragende Kontaktpins und/oder Steckkontakte des Kontaktpinsteckers 100, auf welche nachfolgend Bezug genommen wird.On the
Das Gehäuseelement 110 kann ein oder mehrere Noppen 111 aufweisen, die an zumindest einer Seitenfläche, z.B. an der der Kontaktseite 102 gegenüberliegenden Seitenfläche des Kontaktpinsteckers 100, nach außen vom Gehäuseelement 110 abstehen. Die Noppen 111 können als Führung dienen und/oder als Formschlusselement zum Befestigen der Schutzkappe 130 am kappenlosen Kontaktpinstecker 101. Die Schutzkappe 130 kann hierzu komplementäre Schlitze 131 aufweisen (vgl. z.B.
An der Steckseite 103 ist der Kontaktpinstecker 100 im Wesentlichen offen ausgebildet. An dieser Steckseite 103 weist der Kontaktpinstecker eine Einstecköffnung 113 auf. Die Einstecköffnung 113 kann etwa so groß wie die gesamte Steckseite 103 ausgebildet sein. Insbesondere kann die Einstecköffnung 113 so dimensioniert sein, dass sie lateral von der Gehäusewand des Gehäuseelements 110 begrenzt ist.On the
In der Einstecköffnung 113 weist das Gehäuseelement 110 mehrere Strukturelemente auf, durch die Steckplätze definiert werden können. So weist das im Ausführungsbeispiel gezeigte Gehäuseelement 110 eine erste Steckwand 114 sowie eine zweite Steckwand 115 auf, welche den an der Einstecköffnung 113 gebildeten Innenraum in Teilgebiete unterteilt. Durch diese Teilgebiete werden im Inneren der Einstecköffnung 113 mehrere Steckplätze definiert. Diese Steckplätze sind z.B. in
Die erste Steckwand 114 definiert mit einem Teil der Gehäusewand des Gehäuseelements 110 einen ersten Steckplatz 121, an welchem erste Steckkontakte 151 so angeordnet sind, dass sie elektrisch und/oder mechanisch von einem an den ersten Steckplatz 121 aufgesteckten Steckverbinder kontaktiert werden können. An einem zweiten Steckplatz 122 sind eine Mehrzahl zweiter Steckkontakte 152 angeordnet. An einem dritten Steckplatz 123 ist eine Mehrzahl dritter Steckkontakte 152 ausgebildet. Weiterhin können im Kontaktpinstecker 100 zusätzliche elektrische Kontakte an einem vierten Steckplatz 124, an einem fünften Steckplatz 125 und/oder an einem sechsten Steckplatz 126 ausgebildet sein. An den Steckplätzen 121 bis 126 wird jeweils ein Steckzugang zu elektrischen Kontakten des Kontaktpinsteckers 100 bereitgestellt. Insbesondere wird Steckzugang zu den ersten Steckkontakten 151, den zweiten Steckkontakten 152 und den dritten Steckkontakten 152 bereitgestellt.The first plug-in
Die Steckkontakte 151, 152 und 153 sind als elektrisch leitende Kontakte ausgebildet. Diese Steckkontakte 151, 152 und 153 sind am Gehäuse des Kontaktpinstecker 100 befestigt, insbesondere können sie am Gehäuseelement 110 befestigt sein. Das Gehäuseelement 110 weist dazu eine Steckfläche 116 auf, die z.B. in
Auch bei dem vierten, fünften und sechsten Steckplatz 124, 125 und 126 können die dort angeordneten elektrischen Kontakte mit Nummern versehen sein, im gezeigten Ausführungsbeispiel sind es jeweils die Nummern 1 bis 12. An den Steckplätzen 121 bis 126 können (in den Figuren nicht gezeigte) Steckverbinder so angeordnet werden, dass sie die entsprechenden Steckkontakte 151 bis 153 bzw. die dort angeordneten anderen elektrischen Kontakte elektrisch und/oder physikalisch kontaktieren. Dabei können sie an den Außenwänden abgestützt sein, insbesondere an den Seitenflächen des Gehäuseelements 110. Weiterhin können die Steckverbinder auch an der ersten Steckwand 114 und/oder an der zweiten Steckwand 115 abgestützt sein.In the fourth, fifth and
Die

Die Führungen 117 können im Wesentlichen als Führungshülsen ausgebildet sein. Die Führungen 117 weisen einen hohlen Kern auf, in den die ersten Steckkontakte 151 angeordnet werden können. Die ersten Steckkontakte 151 sind in den in den
Die Steckkontakte 151, 152 und/oder 153 sind im Inneren der Führungen 117 angeordnet und zumindest formschlüssig an dem Gehäuse 110 befestigt.The
Im Folgenden wird näher auf die Befestigung der ersten Steckkontakte 151 des ersten Steckplatzes 121 in den Führungen 117 des Gehäuseelements 110 eingegangen. Die zweiten Steckkontakte 152 und/oder die dritten Steckkontakte 153 können ähnlich in entsprechenden Führungen an dem Gehäuseelement 110 befestigt sein.In the following, the fastening of the
An der Kontaktseite 102 ragen Kontaktpins 140 aus dem Kontaktpinstecker 100 hervor. Diese Kontaktpins 140 sind so beschaffen, dass sie an einer in den Figuren nicht gezeigten Leiterplatte mit einem Reflow-Weichlötverfahren montiert werden können, also z.B. mit SMT-Technik und/oder mittels THR-Technik. Diese Beschaffenheit zur SMT- und/oder THR-Eignung kann sich in der Materialwahl für die Kontaktpins 140 widerspiegeln, in der Form und/oder in der Länge der Kontaktpins 140. Einige der Kontaktpins 114 können im Wesentlichen L-förmig ausgebildet sein, mit einem ersten L-Schenkel aus der Kontaktseite 102 ragen und mit einem zweiten L-Schenkel z.B. am sechsten Steckplatz 126 kontaktiert werden.On the
Entlang der Steckseite 103 des Kontaktpinsteckers 100 ist durchgehend die Versteifungsrippe 112 ausgebildet.The stiffening
An der Gegenseite 104 wird der Kontaktpinstecker 100 von der Schutzkappe 130 begrenzt, welche auf die Noppen 111 des Gehäuseelements 110 geschoben ist.On the
Der erste Steckkontakt 151 des ersten Steckplatzes 121 weist ein Steckende auf, welches aus der Steckfläche 116 heraussteht in Richtung zum Steckende 103 hin. Dieses Steckende des ersten Steckkontaktes 151 bildet z.B. einen männlichen elektrischen Kontakt für einen in den Figuren nicht gezeigten Steckverbinder aus, welcher an den ersten Steckplatz 121 gesteckt werden kann. Am gegenüberliegenden Ende des ersten Steckkontaktes 151 kann dieser z.B. gabelförmig ausgebildet sein und in zwei Gabelspitzen enden, welche elektrisch mit der Platine 160 kontaktiert sind (z.B. mittels THT-Durchsteckmontage und/oder THR-Montage).The
Im dazwischen angeordneten Mittelbereich des ersten Steckkontaktes 151 weist der erste Steckkontakt 151 eine Mehrzahl von Formschlusselementen auf, die in
Hierbei sind zwei der Formschlusselemente, welche in der
Die übrigen vier Formschlusselemente 212 bis 215 des ersten Steckkontaktes 151 sind als Rastnasen ausgebildet, welche in komplementäre Widerhaken und/oder Aussparungen der Führung 117 eingreifen. Mit anderen Worten ist der erste Steckkontakt 151 im Inneren der Führung 117 an dem Gehäuseelement 110 mittels mehrerer Formschlusselemente befestigt, die sich zumindest teilweise in ihrer Ausbildungsform voneinander unterscheiden. So können die Rastnasen eine unterschiedliche Länge aufweisen, und Eingriffselemente unterschiedliche Wirkradien aufweisen, also unterschiedlich dimensioniert ausgebildet sein. Durch die Befestigung des ersten Steckkontaktes 151 mittels dieser Mehrzahl zumindest teilweise unterschiedlich ausgebildeter Formschlusselemente 210 bis 215 an dem Gehäuseelement 110 wird die Befestigungsstabilität erhöht. Selbst falls eines oder mehrere der Formschlusselemente 210 bis 215 bzw. der dazu komplementären Formschlusselemente des Gehäuseelements 110 brechen sollten, ist der erste Steckkontakt 151 immer noch hinreichend gut über die übrigen Formschlusselemente mit dem Gehäuseelement 110 befestigt. Deswegen können für das Gehäuseelement 110 auch Materialien verwendet werden, welche eine geringere Eigenstabilität und/oder eine höhere Sprödigkeit aufweisen als PBT.The other four form-locking
Durch die Ausbildung der Versteifungsrippe 112 am Gehäuseelement 110 wird das Gehäuseelement 110 steifer. Das Gehäuseelement 110 kann alleine das Gehäuse des Kontaktpinsteckers 100 bilden oder als Teil des Gehäuses ausgebildet sein, insbesondere in einem Fall in dem das Gehäuse des Kontaktpinsteckers 100 mehrteilig ausgebildet ist. Durch die Befestigung der elektrischen Kontakte an dem Gehäuseelement 110 mit einer Mehrzahl von Formschlusselementen wird die Widerstandsfähigkeit der besagten elektrischen Kontakte erhöht. Hierbei können insbesondere einige oder alle der Steckkontakte 151 bis 153 mittels einer Mehrzahl von Formschlusselementen an dem Gehäuseelement 110 befestigt sein, da diese beim Ein- und Ausstecken von Steckverbindern eine erhöhte mechanische Belastung erfahren. Die Belastung kann auch während des Betriebs z.B. durch Motorvibrationen auf die Steckkontakte 151 bis 153 erfolgen. Insbesondere können gerade diejenigen der Steckkontakte mit mehreren Formschlusselementen am Gehäuseelement 110 befestigt sein, die im Betrieb erhöhte mechanische Beanspruchung erfahren. Allgemein können an dem Kontaktpinstecker 100 zumindest ein Steckkontakt, bevorzugt zumindest alle Steckkontakte, zumindest eines Steckplatzes derartig mehrfach gesichert formschlüssig am Gehäuseelement 110 befestigt sein.The formation of the
Z.B. durch die Versteifungsrippe und/oder die Formschlusselemente kann die Stabilität des Kontaktpinsteckers so erhöht werden, dass er imFor example, by the stiffening rib and / or the form-fitting elements, the stability of the contact pin connector can be increased so that it is in
