Definitions

  • the invention relates to an electrical contact element to be arranged in a chamber of a plastic housing and bent from a flat sheet metal stamped part using insulation displacement technology of a cable plug connection, a pair of double insulation displacement clamps forming an insertion slot between the elastically bendable clamping legs of the insulation displacement contact of an electrical cable, the electrical conductor of which is surrounded by insulation.
  • the invention further relates to a plastic housing for receiving such an electrical contact element.
  • a generic electrical contact element is known for example from EP-PS 0 416 306.
  • This known electrical contact element has at one end a pair of fork springs, between whose elastically bendable fork spring legs an electrical conductor can be fixed using insulation displacement technology.
  • the other end of the contact element is designed as a pair of spring tongues, between which, for example for electrical contacting, the contact pin of a plug of the electrical plug connection can be inserted.
  • the object of the invention is to extend an electrical contact element in insulation displacement technology of an electrical cable plug connection by a further current outlet connected in parallel.
  • a free end of the electrical contact element is designed as a flat knife for insertion into a coupling and that fork spring or leaf spring pairs for receiving a coupling plug are formed on the free end of the electrical contact element opposite the flat knife.
  • the embodiment with pairs of fork springs is preferred according to the invention.
  • the electrical contact element By designing the ends of the electrical contact element on the one hand as a flat knife and on the other hand as a pair of fork springs, it is possible, in addition to the insulation displacement contact and the insertion of the flat knife into a coupling of an electrical plug connection, the electrical contact element by a further, parallel-connected current outlet, namely that at the other free end trained pair of fork springs to expand.
  • the contact pin of a plug of a further electrical plug connection for electrical contacting can be inserted between the fork spring legs of this pair of fork springs.
  • the clamping legs of the pair of double insulation displacement terminals are symmetrical and have the same elasticity. This configuration ensures that the two clamping legs are deflected evenly during the clamping contact and are subjected to bending.
  • the cable insertion area of a clamping leg is longer, which results in a different elasticity of the two clamping legs.
  • the sheet metal stamped part is folded in two layers in the area of the flat knife. This double-layer design of the flat knife ensures a secure contact in a corresponding coupling of a cable connector.
  • clamping webs with barbs are arranged between the flat blade and the pair of double insulation displacement clamps, by means of which the electrical contact element is immovably clamped in the plastic housing after it has been fully inserted into the plastic housing.
  • the insertion slots of the pair of double insulation displacement clamps and the pair of fork springs or leaf springs and the flat knife are arranged in one plane.
  • a plastic housing for receiving at least one electrical contact element has, in addition to a narrow guide channel for receiving the pair of double insulation piercing terminals and an expanded receiving space for receiving the flat knife on the outside of the housing, at least one elastically deflectable latching arm with a latching hook in order to secure the plastic housing with another housing from being pulled off connect, wherein the latch hook engages in a recess of the other housing.
  • the area of the guide channel adjoining the receiving space for the flat knife for widening the clamping webs of the electrical contact element is widened, the distance between the side walls of the clamping area being somewhat less than the width of the electrical contact element in the region of the clamping webs and the clamping area has a stop surface in order to limit the insertion depth of the electrical contact element.
  • the receiving space for the flat knives in which the flat knives are arranged parallel next to one another, is trough-shaped, so that this receiving area with the flat knives located therein for contacting corresponding ones arranged in parallel in a housing Couplings of another electrical connector can be plugged onto this other housing in a simple manner. Due to the trough-shaped design of the receiving space Without intermediate webs between the flat knives, simple and safe contacting with the other plug connection is made possible, since the side walls of the receiving space on the one hand guide the plug connection with the flat knives when making contact and on the other hand ensure a secure hold on the other housing.
  • FIGS. 3 and 4 an embodiment of an electrical contact element in insulation displacement technology of an electrical cable connector is shown, while with reference to FIGS. 3 and 4, the special design of a corresponding housing for receiving the electrical contact element and its anchoring in the housing is shown.
  • the electrical contact element in FIGS. 1 and 2 consists of a one-piece stamped sheet metal part, from which the electrical contact element 1 is bent by successive bending processes. From the flat sheet metal stamped part an electrical contact element 1 is then obtained, as shown in FIGS. 1 and 2.
  • a free end of the electrical contact element 1 is designed as a flat knife 2, which can be inserted, for example, into the coupling of an electrical plug connection for electrical contacting.
  • the flat knife 2 has a locking hole 2a for secure fixing in the coupling.
  • the electrical contact element 1 In order to be able to contact an electrical cable 3 in so-called insulation displacement technology on the electrical contact element 1, the electrical contact element 1 has two pairs of double insulation displacement terminals 4 arranged parallel to one another. Each of these double insulation displacement pairs 4 consists of two clamping legs 4a, which form an insertion slot 4b between them for the electrical cable 3.
  • both clamping legs 4a are formed symmetrically. Because of this symmetrical embodiment, both clamping legs 4a have the same elasticity, ie. that is, both clamping legs 4a can be elastically bent apart to the same extent when the electrical cable 3 is inserted into the insertion slot 4b.
  • the electrical contact element 1 can be extended at the free end opposite the flat knife 2 by a further, parallel-connected current outlet, as is particularly the case in FIG. 2 and 3 can be seen.
  • a double pair of fork springs 5 is arranged on the free end of the electrical contact element 1 opposite the flat knife 2.
  • Each of these pairs of fork springs 5 consists of two fork spring legs 5a, which form an insertion slot 5b between them.
  • a flat knife 2 of another electrical plug connection can be inserted into the insertion slot 5b between the fork spring legs 5a.
  • the fork spring legs are at the ends 5a inwardly facing contact zones 5c are formed which engage in the locking hole 2a of the flat knife 2.
  • the electrical contact element 1 between the flat blade 2 and the pair of double insulation displacement clamps 4 has clamping webs 6 which are provided on their end faces with barbs 6a for fixing the electrical contact element 1 in a housing 7, as can be seen in particular from FIG. 4.
  • the housing 7 usually consists of a one-piece plastic part. As can be seen from FIG. 3, the housing 7 has a narrow guide channel 7a for receiving the fork spring pairs 5 and the double insulation displacement connector pairs 4 and an expanded receiving space 7b for receiving the flat knife 2.
  • the housing 7 shown in FIG. 3 is designed to accommodate four electrical contact elements 1. To insert the electrical contact element 1 into the housing 7 and to make contact with the electrical cable 3, the electrical contact element 1 with the fork spring pairs 5 is inserted so far from the receiving space 7b into the guide channel 7a until the clamping webs 6 make first contact with the side walls a clamping region 7c arranged between the receiving space 7b and the guide channel 7a. Then the electric cable 3 is inserted into a hole 7d of the housing 7, as shown in FIG. 4.
  • the electrical contact element 1 is then pressed further into the housing 7 until the clamping legs 4a rest against a shoulder 7e of the guide channel 7a and the clamping webs 6 have reached a stop surface 7f. Since the distance between the side walls of the clamping area 7c is somewhat smaller than the width of the electrical contact element 1 in the area of the clamping webs 6, the barbs 6a of the clamping webs 6 latch immovably in the plastic housing.
  • the contacting of the electrical cable 3 with the double insulation displacement pairs 4 takes place when the electrical contact element 1 is inserted into the housing 7 in that the electrical cable 3 is pressed into the insertion slot 4b between the clamping legs 4a. Since the mutually facing edges of the two clamping legs 4a are sharpened, the clamping legs 4a cut into the insulation of the electrical cable 3 until the clamping legs 4a come into contact with the electrical conductor of the electrical cable 3 and thus establish the electrical contact.
  • the contact spring pairs 5 with the insertion slots 5b pointing outwards are arranged near the upper end of the guide channel 7a such that, for example, a Flat knife 2 of a further electrical plug connection between the fork spring legs 5a can be inserted into the insertion slot 5b and thus enables a further current outlet connected in parallel with the double insulation displacement pairs 4.
  • the receiving space 7b for the flat knives 2 is trough-shaped in such a way that all the flat knives 2 of the electrical contact elements 1 arranged in this housing 7 are arranged parallel to one another, the receiving space 7b being formed only by the side walls of the housing 7 which slightly protrude in the longitudinal direction of the flat knives 2 becomes.
  • This trough-shaped configuration of the receiving space 7b for the flat knife 2 enables the flat knife 2 to be plugged onto another housing 7 for contacting another electrical plug connection, the side walls of the receiving space 7b on the one hand facilitating the guidance when plugging on and on the other hand a secure hold guarantee on the other housing and enable coding 7f.
  • various coding webs 7f can be clamped in according to FIG. 6 in the top view, wherein a coding web is shown with the reference number 7g in the drawing.
  • a latching arm 8 arranged on the outside of the housing 7, which engages with a latching hook 8a in a corresponding recess 8b of the attached housing 7 engages.
  • a locking arm 8 ' with a locking lug 8a' is provided, which does not protrude beyond the outer housing.
  • the device is unlocked by pulling the housing.
  • a bevel 8c is provided on the detent 8a '.
