Definitions

  • the invention relates to an electrical connector for connecting parallel to each other, connected with insulating bridges electrical conductors, in particular grid ridges, with an insulating housing for a number of contacts corresponding to the number of poles, each having at least one connecting leg, which is fixed to a connector carrier such as a circuit board can be anchored, at least part of the insulating material housing being displaceable from a first setting corresponding to the conductor insertion position into a second setting corresponding to the conductor connection position, which is secured, for example by latching.
  • An electrical connector of this type has become known, for example, from EP-PS 0 203 097.
  • a two-part insulator housing is proposed, the lower part of which supports the contact elements and is held by them on the connector carrier when they are soldered to the circuit board.
  • An upper part of the insulating material housing is designed as a closure cover which can be locked with the lower part and which at the same time has an attachment which presses the conductor onto the connecting leg of a contact spring and thus holds the conductor in the contact area in a clamped manner.
  • the conductor is an elastic flat cable.
  • the invention is based on the object, while maintaining the conductor contact, which is essentially made by clamping, to make it particularly safe even in cases of special conductor stress, particularly by tensile forces.
  • the invention solves this problem essentially and primarily by the fact that on the outside of the movable part of the insulating material housing there is at least one web extending on its side facing away from the connector carrier transversely to the direction of displacement of the insulating material part with respect to the connector carrier, which is at least in the conductor connection position of the Isolierstoffgeophuses penetrates a corresponding opening in an insulating material bridge of the conductor and thus ties the conductor to the insulating material housing.
  • the web which essentially corresponds to the grid web cable in this way, acts as a strain relief in that tensile forces exerted on the line are largely absorbed on the displaceable part of the insulating material housing and therefore cannot immediately affect the contact point in such a way that the conductor is pulled out of it. Because the strain relief on the sliding part of the insulating housing is arranged, which is locked in the conductor clamping position with a second part of the insulating housing or directly with the contact element, so this locking must first be overcome before adverse forces are exerted on the terminal zone of the contact connection itself.
  • the principle of the invention therefore consists essentially in the fact that one makes use of the existing for the strain relief by the latching connection between the two parts of the insulating housing or between the insulating housing and the contact element for strain relief.
  • the electrical connector designated in its entirety by 10, has an insulating material housing 11 and a number of contact elements 12 corresponding to the number of poles. As shown in FIGS. 2 and 3 and 5 and 6, the contact elements 12 of the same type are arranged in parallel one behind the other in the insulating housing 11.
  • Each contact element 12 is essentially fork-shaped and has a connecting leg 13 for attachment to a connector carrier 14.
  • the connecting leg 13 is a solder leg of the contact element 12 and the connector carrier 14 is a printed circuit board.
  • a fork leg forms a clamping leg 15 which is resiliently movable in the plane of the drawing in FIG. 1.
  • the second fork leg serves as a bearing section 16 for holding and movably guiding the insulating material housing 11.
  • This bearing section 16 is again fork-like in design; it has the two fork legs 17 and 18, of which, in the exemplary embodiment, the fork leg 18 with respect of the opposite fork leg 17 is resilient.
  • the fork leg 18 has a locking recess 19 and the facing inner wall of the insulating material housing 11 has a corresponding locking cam 20 which, in mutual engagement, detachably lock the setting of the insulating material housing 11 close to the connector carrier with respect to the contact element 12 (see FIG. 4).
  • Another locking recess 19 ′ on the fork leg 18 serves to temporarily lock the setting of the insulating material housing 11 remote from the connector carrier with respect to the contact element 12 according to FIG. 1.
  • a clamping zone K is formed below the conductor insertion opening 25 on the insulating material housing side, within which the stripped end 26 of an electrical conductor 27 inserted through the opening 25 presses against a clamping lug 24 of the clamping leg 15 and presses the clamping leg 15 against its spring restoring force to the outside.
  • a clamping abutment section 31 is located opposite the clamping lug 24 in the insulating material housing 11. Here, the inserted conductor 26, as illustrated in FIG. 4, is held in contact.
  • a plate or tab 30 is provided in the extension of an outer wall 29 of the insulating material housing 11, which plate is connected to the housing wall 29 in one piece and in a material-uniform and pivotable manner via a film hinge 32.
  • the tab 30 On its side facing the level of the conductor insertion openings 25, the tab 30 carries a plurality of webs 34 in the form of two-legged hooks, the legs 35 of which are connected to the tab 30 for transverse penetration and the adjoining hook-shaped angled legs 36 for the rear engagement behind an opening 37 which is attached in associated insulating material bridges 33 of the grid web line 27.
  • the stripped ends 26 of the conductor 27 are inserted through the conductor insertion openings 25 into the later clamping zone K.
  • the tab 30 is initially directed outward (see dashed lines in Fig. 1).
  • the tab 30 is then folded against the grid web line 27, the webs 34 initially reaching freely through the openings 37 in the insulating material bridges 33 (FIG. 1).
  • the hook-like overlapping of the web leg 36 over the lower edge of the opening 37 also holds the grid web line 27 to the tab 30 when it should be bent away from it.
