Definitions

  • the invention first relates to an electrical contact, especially for lamp holders, connection or distribution terminals or the like.
  • an electrical contact especially for lamp holders, connection or distribution terminals or the like.
  • electrical conductors such as wires or Contact pins
  • the contact body forms a kind of frame component on which the contact spring is held, and wherein between at least one inner surface of the Contact body and contact sections of the contact spring contact zones are formed according to the preamble of claim 1.
  • DE 93 09 139 U1 shows and describes a lamp holder for Halogen lamps with a contact carrier made of insulating material and two so-called clamping contacts. Every terminal contact that does the job has the electrical connection between a connecting conductor and To manufacture a lamp contact pin is formed here in two parts. One part is box-shaped and is pressed into the insulating body, where he sits with the help of a barbed latch clawed against falling out. The one in the cavity of the box-shaped The first part inserted second part consists of a essentially S-shaped leaf spring. This shows itself in essentially straight extending end with a front Clamping edge and another bent end.
  • the end with the clamping edge forms with the adjacent wall of the box-shaped Part of a screwless terminal for the stripped End of an electrical conductor to be inserted.
  • the other, Round curved end serves to place the lamp contact pin between himself and the adjacent inner wall of the box-shaped body to contact by adhesion.
  • the design of contacts consists of two parts to the extent that parts of different materials are used can be. So it is particularly recommended to use the contact spring e.g. to form from a chrome-nickel strip, the excellent Has spring properties even at high temperatures.
  • the other part of the contact can e.g. be a copper part, which is characterized by optimal electrical conductivity and high mechanical Stability distinguishes.
  • the two-part Terminal as it is the subject of DE 93 09 139 U1 advantageous.
  • the terminals require a considerable amount of space. They are therefore suitable e.g. not for installation in halogen lamp sockets smaller diameter, such as for use in so-called trimmings with a Outside diameter of about 10 mm and an inside diameter of only approx. 8 mm are required.
  • Such a halogen lamp holder is in DE 195 10 623 C2 shown and described. To make the necessary minor here. Mounting dimensions To ensure the contacts, they are relatively flat and crimped onto the stripped ends of the conductors. On in this way two relatively small contacts can be made in the same cross-sectional area of the socket body.
  • the contact body is essentially U-shaped in cross section is that the contact spring has a base portion that is U-shaped of the contact body to form a tube and the contact sections the contact spring on the narrow ends of the elongated Base section are molded and from the same Extend the flat side of the base section away such that the two contact zones in the longitudinal direction of the contact one behind the other are arranged.
  • the essential essence of the invention is therefore in Design of the contact as a tube contact with a small cross-sectional profile.
  • the contact spring in not a cage-like one Contact body housed, but initially complements the essentially only U-shaped contact body to the tube contact. Consequently, the contact spring is not built into the contact body, but part of its scope.
  • This idiosyncratic Construction allows the contact to be elongated can be extremely small in cross section.
  • suitable Contacts of the type according to the invention for installation in insulating material socket bodies small diameter, especially for halogen lamp holders, for use in trimmed tubes or similar of 10 mm Diameters are suitable.
  • This contact also approximated the shape of an im Cross-section of small tube, but remains over the entire length of the contact a longitudinal slot open, which increases the stability of the contact is low.
  • there is all contact so be the portion representing the contact body as well as the Section forming contact springs from a one-piece component and consequently only from a single material, i.e. either e.g. Copper or e.g. Chromium-nickel steel. With such a contact the objectives of the invention cannot therefore be achieved.
  • the elongated Base portion of the contact spring as a substantially flat strip formed, the ends of which slant towards the inside of the central Web of the U-shaped contact body are bent pointing.
  • Another embodiment according to the invention provides that the U-legs of the contact body mounting tabs are molded to connect the contact spring to the contact body, wherein the the fastening tabs by reaching around the edge of the base portion of the contact spring on the contact body can set. By simply bending the fastening tabs the strip-shaped contact spring with the U-legs of the Contact body to an overall very stable and compact Contact element firmly connected.
  • the Base section of the contact spring is provided with edge notches, into which the fastening tabs of the contact body are inserted.
  • edge notches equal or only slightly is larger than the outer distance of the U-legs of the contact body from each other. The edge notches thus allow to a certain extent Way a "shape integration" of the contact spring in the contact body.
  • Stability of the miniaturized contact is a feature advantageous which consists of the contact zones being in the same Cross-sectional areas of the contact are arranged like the fastening tabs.
  • the highest possible load in the contact zones during operation exerts reaction forces exactly where the contact spring is fixed on the contact body. Those zones and areas who have no direct connection with each other will not strained and can therefore e.g. also do not bulge or deform in any other way.
  • the arrangement of a lamp is preferably further made such that in an area between the contact zones from the Contact body released a stop tab and so in the Contact body is deformed into that with at least one of their narrow edges forms an insertion limit.
  • notched and bent insertion limits are also in, for example US 4 084 876 A discloses.
  • the respective leader meets vertically on the superscript wide area of the section and is thus directed transversely to its bending axis, whereas the peculiarity of the feature of the invention is that not wide area, but the narrow edge of the bent Stop tab forms the insertion limit.
  • the material itself therefore does not need to absorb the resulting forces and can therefore be thin.
  • the free ends of the contact sections of the contact spring essentially straight against the inside of the central web of the U-shaped Contact body pointing and each have a clamping edge for train a leader.
  • Such contact would come in particular as or in a connection or connection terminal, as they are considered is described in principle in US 4,084,876 A and is used to two substantially axially opposite conductor ends take.
  • Another embodiment provides that the end of the one contact section of the contact spring essentially straight against the inside of the central web of the U-shaped contact body runs in a pointing manner and forms a clamping edge for a conductor, while the other contact portion of the contact spring from one Bend is formed, one against the inside of the central web of the U-shaped contact body pointing Section leads away from the central web and a pressure contact zone for a contact pin such as lamp contact pin. The contact pin is then out of contact with a defined force can be pulled out again, so it is not clamped. That contact is ideal for installation e.g. in a halogen lamp holder.
  • the invention relates to a lamp holder, in particular a halogen lamp socket comprising a socket body Made of insulating material with an elongated shaft and one with push-through openings for contact pins provided plate-like head and with channels for receiving contacts for connecting conductor ends for the power supply of the contact pins, the socket is characterized by contacts according to the invention.
  • a contact that is used for anchoring in an insulator a barb-like from the base portion of the contact spring acting latch is cut out and shaped outwards, important if the locking tongue has a notch that the latch tab into a wider base and a narrower end tab divided so that the leading edge of the wider base one Stop for support on the reveal of a window in the Insulating body of the socket forms, in which only the narrower Can engage end tongue.
  • the plug lock of the contact in the insulator the ensures that e.g. by pulling on the inserted conductor Locking tongue cannot deform and consequently also - even under increased pull-out forces - the contact does not come out of the insulating body can leak. This prevents a short to ground Isolation body surrounding trimmed tube.
  • the invention also relates to a Terminal block using a contact with features according to the invention, the contact of is surrounded by a tubular insulating sheath, which is preferred is formed by a shrink tube.
  • a contact designated 10 in its entirety is in two parts educated. It comprises a contact body 11 and a contact spring 12th
  • the contact body 11 is made of a flat sheet metal blank 13 e.g. made of copper, essentially U-shaped, so that it defined three Sections, namely a U-web 14 and two to each other has parallel U-legs 15.
  • the U-web 14 is not flat, but as e.g. out Fig. 1 can be seen, slightly curved outwards.
  • Over the free ends of the U-legs 15 each project in pairs on two in the axial direction spaced areas mounting tabs 16, the Function is explained below.
  • the contact spring 12 is made from a blank 17 in particular Chrome-nickel steel sheet shaped. It is divided into an im Cross section of flat rectangular and otherwise elongated base section 18, both ends of which are bent. The end section of the lower end 19 in FIG. 3 is essentially rectilinear, while the upper end 20 there still has a bend 22. This will be discussed later.
  • the base section 18 of the contact spring 12 notches 22 on the arrangement and position of the fastening tabs 16 of the contact body 11 assigned. 5 and 6 clearly illustrate their Interaction, namely the edge engagement of the fastening tabs 16 in the edge notches 22 and reaching around bent mounting tabs 16 behind the back of the Base section 18 of the contact spring 12. As shown in FIGS. 5 and 6, is by this assembly of contact body 11 and Contact spring 12 a contact 10 closed all round created, which can be called a tube contact.
  • the lower one runs in essential straight section 19 of the contact spring 12 obliquely against the rear inside 14a of the contact body 11 and forms together with this a screwless connector for with regard to FIG. 7, stripped conductor ends to be inserted from below out. If a conductor end is inserted, the straight section becomes further up and out of the inner surface 14a until the stripped end through the gap between the clamping edge 23 and can pass through the inner rear surface 14a and the clamping edge 23 holds the conductor against pulling forces acting in the sense of loosening.
  • the existing contact zone 31 is approximately at the level of the two lower fastening tabs 16.
  • Fig. 10 shows the contact in the position of Fig. 7 as a component a halogen lamp holder 25, the insulating body with 26 is designated.
  • the insulating body 26 is divided into a shaft 27 and in contrast, a widened head 28.
  • the diameter of the head 28th is only about 10 mm and the shaft diameter 29 accordingly the wall thickness of the trimmed tube is significantly smaller.
  • each contact pin is from the bend 21st of the upper contact spring end with reference to FIG. 10 and kept electrically contacting.
  • connection conductors become a lower one in axial alignment from below Opening 33 is inserted into the further contact zone designated 32.
  • the contact according to the invention has another special feature on, which is that in the U-web 14 of the contact body 11 a stop tab 43 is released and into the interior 22 of the Contact 10 is molded into it.
  • This stop tab 43 serves as Insertion limit for the one to be inserted from below with regard to the figures electrical conductor and / or for the to be inserted from above Lamp pin.
  • the special feature of the stop plate 43 is that they start from the conductor and / or lamp contact pin its narrow edge is contacted. Forces acting on them are thus exercised in the direction of the bending line 44 around which the Stop tab 43 was deformed. As a result, the stop tab 43 particularly stable or can, in order to perform its function safely, be quite thin. 13 shows the stop tabs 44 with a view on their narrow abutment surfaces or edges.
  • FIG. 15 While previously the contact 10 individually or in combination with a halogen lamp holder 25 is shown in FIG. 15 another embodiment. There is a contact 10 as Connection or connecting terminal 46 designed for two conductors, which is why both ends 19 and 20 of the contact spring 12 conductor clamping edges 23 have at their free ends.
