Description

SUBASSEMBLY FOR AN ELECTRICAL PLUG TYPE CONNECTOR AND KIT
The invention relates to a subassembly for an electrical plug type connector which can be connected to a mating connector in an insertion direction. The invention further relates to a kit for producing at least two differently constructed electrical plug type connectors.
Connector systems in which universal inserts can be adapted to different fixing elements by means of different housings are known. A first contact securing member secures contact elements which are inserted into the universal insert in an insertion direction against falling out or being removed from the universal insert. A second contact securing member which can be introduced into the plug type connector prevents the first contact securing member from opening. A correct relative position between the housing and the universal insert is achieved by means of different positioning elements. The assembly of such an electrical plug type connector from its individual components is very complex and takes several steps.
An object of the present invention is to provide a connector system in which the assembly is simplified over previous systems.
The object is achieved by a subassembly for an electrical plug type connector comprising a housing and a universal insert having a first contact securing member which, in the secured state, prevents relative movement between the universal insert and contact elements inserted into the universal insert, and the housing having a receiving chamber open at one end for the universal insert and a second contact securing member which is formed on the housing in one piece and which blocks opening of the first contact securing member when the universal insert is correctly inserted into the receiving chamber. The universal insert forms a kit for a connector system together with two differently constructed housings, in which the universal insert can be inserted.
A universal insert can be inserted into the receiving chamber of the housing according to the invention. Conductors of a cable can be fitted to the universal insert. For example, contact elements can be fitted to the conductors of the cable and can be introduced into the universal insert. Together with the universal insert, the housing forms an electrical plug type connector which can be connected to a mating connector in an insertion direction. The second contact securing member prevents the first contact securing member from opening, for example, by blocking deflection of the first contact securing member. This allows the universal insert to be inserted simply and correctly in a single step. Since the second contact securing member is integral with the housing, that is to say that the housing and the second contact securing member are a single component, production and assembly are possible in a time-saving and cost-saving manner.
Various developments of the invention which are advantageous per se and which can be freely combined with each other are described below.
The second contact securing member may project counter to the insertion direction into the receiving chamber, which may allow a particularly positive-locking and therefore stable connection.
The second contact securing member may be located at the other end of the receiving chamber opposite the open end in the insertion direction, which may facilitate the insertion operation.
The second contact securing member may simultaneously be a positioning member or spacer which ensures a correct relative position between the universal insert and the housing.
The first contact securing member may be a resiliently deflectable contact securing member. The second contact securing member can prevent, for example, block, a deflection of the first contact securing member. In an advantageous embodiment, the first contact securing member is a resiliently deflectable finger or arm having an engaging face for the contact elements. The first contact securing member can close automatically if the contact elements are correctly inserted into the universal insert. For example, the first contact securing member can be snap-fitted or engage in corresponding counter-elements of the contact elements.
The first contact securing member may be a snap-fit element. For example, the first contact securing member can be a lug, for example, a snap-fit lug, which snap-fits automatically into the contact elements. Therefore, the first contact securing member may instead be constructed to be planar in order to be able to apply a more powerful securing force. The lug may extend, for example, in the insertion direction and transversely relative to the insertion direction. The lug may be deflectable, for instance, transversely relative to the insertion direction and transversely relative to its planar extent.
The second contact securing member may secure only a single contact element. Alternatively, a single second contact securing member may also simultaneously secure a plurality of first contact securing members.
The second contact securing member may be of rib-like form. Such a planar embodiment results in a large contact surface-area between the universal insert and the second contact securing member.
This allows secure positioning. Furthermore, such a blade-like or rib-like second contact securing member is stable. Such a rib may extend in particular counter to the insertion direction and in a direction which is transverse relative to the insertion direction. The thickness of the rib may be constant in the insertion direction. The width of the rib may also be constant transversely relative to the insertion direction. Alternatively, the thickness and/or the width may taper towards the open end in order to configure the introduction of the universal insert as simply as possible and to guide it.
A rib-like construction blocks relative movement of the universal insert relative to the housing in a first transverse direction. In order also to block relative movement in a second transverse direction, there may be provided on the rib-like second contact securing member positioning elements which extend perpendicularly away from the rib-like second contact securing member. In particular, such positioning elements may extend in the insertion direction. Therefore, they can act as an additional guide for the universal insert.
The blade-like or rib-like second contact securing member may extend transversely relative to the insertion direction from one wall to the other wall of the receiving chamber. The second contact securing member can therefore be secured to the walls or directly merge into the wall if the second contact securing member is produced together with the wall, for example, by injection-moulding. Such a construction considerably increases the contact length between the housing and the second contact securing member in the insertion direction, which increases the stability of the second contact securing member. Deformation or damage during insertion or introduction of the universal insert may be prevented. Furthermore, the contact surface-area between the second contact securing member and the universal insert can be increased by using the complete width of the inner space.
The receiving chamber of the housing can be delimited at the other end opposite the open end by a base plate which extends transversely relative to the insertion direction. A base plate can prevent the universal insert from being introduced too far into the housing. Therefore, the base plate can act as a stop for the universal housing. The base plate can further act as a base for the second contact securing member.
The base plate may extend particularly along the entire inner contour of the housing. It may extend between two walls of the housing.
Channels for conductors of the electrical plug type connector or the mating connector can be provided in the base plate. Furthermore, air channels can be provided in the base plate and allow air to be discharged during assembly and therefore easier assembly.
The second contact securing member can be connected to the base plate. In particular, the second contact securing member can be arranged on the base plate. The second contact securing member and the base plate can be integrally connected to each other. In an advantageous embodiment, all the elements of the housing are integrally connected to each other. For example, the housing may have a second contact securing member and a base plate which are integral with each other. The entire housing may be a single injection- moulding component.
The housing may have a mating connector receiving chamber for receiving the mating connector. The mating connector receiving chamber may adjoin the receiving chamber in the insertion direction. A base plate can be fitted between the receiving chamber and the mating connector receiving chamber.
In order to allow secure connection to the mating connector, there may be provided in the mating connector receiving chamber a guide element which is preferably in the form of a kojiri rib and which extends in the insertion direction and counter to the direction of the second contact securing member. The guide element may extend, for example, away from a base plate.
Naturally, a plurality of second contact securing members may also be provided in the housing.
The one or more second contact securing member(s) can be arranged symmetrically in the housing. A single second contact securing member can be constructed symmetrically. For example, it may be point-symmetrical or axially symmetrical. There may also be provided rotational symmetry, for example, 180° rotational symmetry. That construction allows a universal insert to be inserted in different manners. A complex orientation of the universal insert relative to the housing may thereby become superfluous. In the case of a plurality of second contact securing members, they may have, for example, symmetry relative to a centre of the housing. In particular, their positions may be symmetrical.
A universal insert which can be inserted into the receiving chamber forms a subassembly for an electrical plug type connector together with a housing according to the invention. The universal insert can be introduced or inserted into the receiving chamber of the housing in the insertion direction. The universal insert is advantageously at least partially complementary with respect to the housing in terms of cross-section. The universal insert and the housing can be connected to each other in an at least partially positive-locking manner at least transversely relative to the insertion direction.
The universal insert may fill the receiving chamber of the housing completely or partially. Alternatively, the universal insert may project out of the receiving chamber in the assembled state.
A universal insert may have a pocket which receives the second contact securing member in a positive-locking manner in the inserted state. Such a pocket may be a counter-element or a receiving element for the second contact securing member. Therefore, a pocket can block a relative movement of the universal insert not only in one direction but also in the opposite direction. The pocket may be spaced apart from the housing at least in portions transversely relative to the insertion direction.
The pocket may be constructed so as to be shaft-like if the second contact securing member is rather pin-like. In such a construction, relative movement is blocked in all directions transversely relative to the insertion direction.
The pocket may be constructed in a slot-like manner, specifically in order to receive riblike or blade-like second contact securing members.
The pocket may extend transversely relative to the insertion direction in order to be adapted to second contact securing members which extend transversely relative to the insertion direction. In particular, the pocket may extend over the entire cross-section transversely relative to the insertion direction in order to receive a second contact securing member which extends transversely relative to the insertion direction from one wall to the other wall.
The universal insert may have a plurality of pockets in order to receive a plurality of second contact securing members. Individual pockets may be constructed in such a manner that they can receive second contact securing members of different housings. The universal insert may also have a plurality of pockets, only one of which is fitted to a second contact securing member of a housing.
A plurality of pockets can be slot-like and extend parallel with each other. Intersecting slot-like pockets can further be provided.
When the pocket is constructed in a slot-like manner, a single second contact securing member can act as a second contact securing member for a plurality of first contact securing members. For example, a plurality of first contact securing members can be arranged on two opposing walls of the slot. The second contact securing member can simultaneously secure both first contact securing members, for example, in that it blocks deflections of the first two contact securing members.
A single pocket can be constructed symmetrically so that the universal insert can be introduced into the housing in the insertion direction in different rotation positions.
A plurality of pockets can be arranged symmetrically so that the universal insert can be introduced into the housing in the insertion direction in a plurality of rotation positions.
The first contact securing member can automatically change into the secured state by means of the resilient force of engaging or snap-fit elements, in particular if the contact elements inserted are correctly inserted.
For precisely positioning an end face of the universal insert relative to a base plate of the housing transversely relative to the insertion direction, there can be fitted to the base plate and/or the end face positioning teeth which cooperate in the completely assembled state with corresponding recesses or positioning teeth of the universal insert.
In a subassembly according to the invention, a spacing collar may be in a state associated with the open end of the housing. Such a spacing collar can be arranged at the open end in the assembled state. The spacing collar may be arranged, for example, on the housing and/or on the universal insert. The spacing collar can partially take on the positioning or spacing function of a positioning member or support it. The spacing collar can ensure that the universal insert and the housing are also spaced apart from each other at the open end. For example, an end which is thickened transversely relative to the insertion direction can be fitted to the housing and/or the universal insert.
The first contact securing member can be constructed in such a manner that it strikes the second contact securing member in a frontal manner in the insertion direction and blocks additional movement of the universal insert relative to the housing if a contact element is introduced incompletely or incorrectly into a receiving chamber of the universal insert.
A third contact securing member which prevents movement of the housing relative to the universal insert may be in a state associated with the open end of the housing. In the assembled state, a third contact securing member can be arranged at the open end. For example, the third contact securing member may be located on the housing and/or on the universal insert. A third contact securing member can be constructed by an engaging or snap-fit mechanism. A resiliently deflectable element can snap-fit, after the universal insert has been introduced, into a securing position, from which it is extracted again only by the third contact securing member being opened manually.
A kit according to the invention comprises at least one universal insert and at least two differently constructed housings, the universal insert being able to be joined to each housing so as to form a subassembly according to the invention for an electrical plug type connector. The housings can be constructed in such a manner that the electrical plug type connector can be connected to different fixing elements. In particular, the housings can be constructed so as to at least partially complement corresponding fixing elements.
The housings in a kit according to the invention may each have different advantageous embodiments, as mentioned above.
The invention is explained in greater detail below with reference to embodiments and the drawings. The features which are different in the individual embodiments can be freely combined with each other in accordance with the above explanations. Furthermore, individual features in the embodiments may also be omitted in accordance with the above description if the advantage connected with this feature is not the important aspect in the specific application. In the drawings:

Figure 5 is a schematic perspective view of a subassembly according to the invention in the assembled state, and a mating connector;
Figure 6 is a schematic perspective view of another subassembly according to the invention in the assembled state, and a mating connector.
Figure 1 is a cross-section through a housing 1 according to the invention in a longitudinal plane. The insertion direction S in which the plug type connector can be combined with the mating connector is in the plane of section.
The housing 1 has a receiving chamber 2 which is open at one end. A universal insert can be introduced into the open end 3 of the receiving chamber 2. At the other end 4 which is opposite the open end 3 of the receiving chamber 2 in the insertion direction S, two second contact securing members 5 project counter to the insertion direction S into the receiving chamber 2.
The second contact securing member 5 A is spaced apart at a spacing Dl from a first wall Wl of the inner contour C of the receiving chamber 2. The second contact securing member 5 A extends parallel with the first wall Wl. The second contact securing member 5B is spaced apart at a spacing D2 from a second wall W2 of the inner contour C of the receiving chamber 2. The second contact securing member 5B extends parallel with the second wall W2. The second contact securing member 5B further extends parallel with the second contact securing member 5A.
The thickness Tl of the second contact securing member 5A measured in the thickness direction T is constant in the insertion direction S. The thickness T2 of the second contact securing member 5B measured in the thickness direction T is also constant in the insertion direction S. Both second contact securing members extend in a width direction B. The width direction B is perpendicular to the thickness direction T and perpendicular to the insertion direction S. The thickness direction T is further perpendicular relative to the insertion direction S. The two second contact securing members 5 therefore have a planar construction. The second contact securing members 5 are rib-like or blade-like.
At the other end 4 opposite the open end 3 in the insertion direction S, the receiving chamber 2 is delimited by a base plate 6. The base plate 6 extends along an entire cross- section of an inner contour C of the housing 1. In order to be able to allow air to be discharged, air channels 7 are provided in the base plate 6.
The two second contact securing members 5 are connected to the base plate 6. Therefore, the base plate 6 is a basis for the two second contact securing members 5.
A height HI of the second contact securing member 5 A measured in the insertion direction S is smaller than a height H2 of the second contact securing member 5B measured in the insertion direction S. It is thereby possible to prevent a universal insert which is intended to be inserted into the receiving chamber 2 from being incorrectly inserted.
The housing 1 further has a mating connector receiving chamber 8, in which a mating connector (not shown) can be introduced. In order to prevent the mating connector from being introduced obliquely, there is fitted in the mating connector receiving chamber a guide element 60 which is in the form of a kojiri rib 9 and which ensures linear guiding of the mating connector. The kojiri rib 9 extends away from the base plate 6 in the direction which is counter to the direction of the second contact securing members 5. Therefore, the kojiri rib 9 extends in the insertion direction S. All the components of the housing 1 shown here are integrally connected to each other. The entire housing 1 is a single injection-moulding component.
Figure 2 is a cross-section of a subassembly 10 according to the invention for a plug type connector 10' comprising a housing 1 according to the invention and a universal insert 11 in the assembled state. The universal insert 11 is completely inserted into the receiving chamber 2 of the housing 1. To that end, it was pushed in the insertion direction S into the receiving chamber 2 until it abutted the base plate 6 which acts as a stop 12.
The universal insert 11 has a plurality of pockets 13 which extend in an insertion direction S. The pockets 13 shown here are slot-like pockets 14 which also extend further in the width direction B which extends perpendicularly relative to the insertion direction S. The second contact securing members 5 are received in the slot-like pockets 14. The slot-like pockets 14 are positive-locking with respect to the second contact securing members 5. They extend parallel with the insertion direction S and therefore space an end face 15 of the universal insert 11 apart from the housing 10 at least in cross-section. They ensure that the universal insert 11 is centrally positioned in the housing 10. Therefore, the second contact securing members simultaneously act as positioning members 40 in this instance.
The universal insert 11 has a first contact securing member 16 in the form of a plurality of deflectable arms 17, only one of which can be seen in this sectional view. The first contact securing member 16 can secure in the secured state G shown here contact elements (not shown) which can be fitted in a contact element chamber 18. A relative movement between the contact elements and the universal insert 11 is no longer possible in that secured state G, particularly not in the insertion direction S. In order to release the contact elements from the universal insert 11, the resiliently deflectable arm 17 would have to be deflected in the release direction L. If the universal insert 11 were not fitted to the housing 1, the resiliently deflectable arm 17 could move in the release direction L because a pocket 13 in the universal insert 11 is present in this direction. However, in the assembled state of the universal insert 11 and the housing 1 shown in this instance, the second contact securing member 5 A engages in the first pocket 13A and thereby blocks movement of the resiliently deflectable arm 17 of the first contact securing member 16 in the release direction L, and consequently opening of the first contact securing member 16. Therefore, the second contact securing member 5 prevents the first contact securing member 16 from opening by blocking movement of the resiliently deflectable arm 17 in the release direction L.
If a contact element is incompletely introduced into the contact chamber 18, the universal insert 11 cannot be completely introduced into the receiving chamber 2 because the second contact securing member 5 collides with the resiliently deflectable arm 17 in a frontal manner and blocks relative movement of the universal insert 11 relative to the housing 1 in the insertion direction S.
The subassembly 10 shown here has a third contact securing member 19 which blocks relative movement between the housing 1 and the universal insert 11. This is constructed in the form of a snap-fit mechanism 20. A plurality of snap-fit arms 21 of the snap-fit mechanism 20 are fitted to the housing 1. The resiliently deflectable snap-fit arms 21 engage behind the universal insert 11 and prevent the universal insert 11 from falling out of the housing 1.
The subassembly 10 shown has a spacing collar 22 which is associated with the open end 3 of the receiving chamber 2. In the assembled state shown here, therefore, the spacing collar 22 is located at the open end 3 of the receiving chamber 2 of the housing 1. The spacing collar 22 causes the universal insert 11 also to be spaced apart from the housing 1 at the open end 3, that is to say that the universal insert 11 is centrally fitted to the open end 3 in the housing 1.
Figure 3 is a perspective view of a housing 1 according to the invention. The view is directed into the receiving chamber 2. The outer front contour 23 of the housing 2 is adapted to a fixing element.
The two second contact securing members 5, 5 A, 5B which simultaneously also act as positioning members 40 can be seen in the receiving chamber 2. Both second contact securing members 5A, 5B extend in the width direction B over the entire inner width IB of the receiving chamber 2. They extend from a third wall W3 of the inner contour C as far as a fourth wall W4 of the inner contour C. At transition locations 50, they merge into the inner contour C of the receiving chamber 2. Both the second contact securing members 5 and the receiving chamber 2 are thereby very stable and capable of bearing loads.
The two second contact securing members 5, 5 A, 5B act, owing to the great width thereof, as a second contact securing member 40 for a plurality of first contact securing members for a plurality of contact elements.
In order also to be able to hold an introduced universal insert (not shown) very precisely in the width direction B, the base plate 6 has positioning teeth 24 which engage in corresponding counter-elements on the universal insert.
In order to allow air to be discharged during the insertion operation, air channels 7 are arranged in the base plate 6. There are further provided insertion channels 25 for introducing conductors.
Figure 4 is a perspective view of a subassembly 10 according to the invention for a plug type connector 10'. The universal insert 11 is not yet connected to the housing 1.
The universal insert 11 has two pockets 13 in the form of slot-like pockets 14. Both slotlike pockets 14 extend over the entire width BU of the universal insert 11.
From this perspective, it is possible to see into the mating connector receiving chamber 8 of the housing 1. It is possible to see the kojiri rib 9 which linearly guides a mating connector which can be introduced into the mating connector receiving chamber.
The housing 1 further has a seal 26 which can seal a resultant connection together with a fixing element.
Figure 5 is a perspective view of a subassembly 10 according to the invention for a plug type connector 10' together with a mating connector 26. The subassembly 10 according to the invention comprises a housing 1 and a universal insert 11 inserted therein. The mating connector 26 can be fitted onto the subassembly 10 according to the invention counter to the insertion direction S. An inner element 27 of the mating connector 26 is received in the mating connector receiving chamber 8 of the housing 1. A kojiri counter-element 33 cooperates with the kojiri rib present in the mating connector receiving chamber 8. An outer element 28 of the mating connector 26 can be guided externally over the housing 1. An engaging device 29 comprising an engaging projection 30 and a resiliently deflectable element 31 blocks relative movement between the mating connector 26 and the subassembly 10 in the insertion direction S in the assembled state. The plug type connection 32 produced in that manner can be connected to a fixing element (not shown). An adapted outer front contour 23 of the housing 1 ensures that a positive-locking connection occurs between the housing 1 and corresponding counter-elements of the fixing element. There is shown here a first variant 10A of a subassembly 10A for a first plug type connector 10Ά and therefore a first variant 32A of a plug type connection 32.
Figure 6 shows a second variant 1 OB of a subassembly 10 for a second electrical plug type connector 10'B and therefore a second variant 32B of a plug type connection 32. In order to be adapted to the shape of another fixing element, the housing 1, Γ has a differently formed outer front contour 23, 23'. The outer front contour 23' shown here is instead rectangular in cross-section.
The housing Γ shown here also has a third contact securing member 19 in the form of resiliently deflectable snap-fit arms 22 which block a relative movement of the universal insert relative to the housing Γ.
A kit according to the invention comprises at least one universal insert 11 and two housings 1 which are constructed differently, the universal insert 11 being able to be joined to each of the housings 1 so as to form a subassembly 10, 10A, 10B for an electrical plug type connector 10, 10Ά, 10'B. For example, such a kit may comprise a universal insert 11 and the housings Γ, 1" which are shown in Figures 5 and 6.
