Definitions

  • the invention relates to an electrical connector according to the preamble of independent claim 1.
  • 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 web which essentially corresponds to the grid web guide in this way, acts as strain relief in that tensile forces exerted on the line are largely absorbed at 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. Since the strain relief is arranged on the displaceable part of the insulating housing, which in the Conductor clamping position with a second part of the insulating material housing or is locked directly with the contact element, this locking must first be overcome before any adverse forces are exerted on the terminal zone of the contact connection itself.
  • the principle of the invention therefore consists essentially in that one takes advantage of the existing for the strain relief by the latching connection between the two parts of the insulating material housing or between the insulating material housing and the contact element.
  • the insulating housing is not arranged to be relatively displaceable relative to the connector carrier or to the contact elements.
  • the nose is molded onto a tab that is under constant locking or engagement tension. This tab is not hinged to the housing, but can only be swung out against the inherent spring force by bending it outward from the locking position, so that the conductor can be removed from the housing part if necessary.
  • An electrical connector of the type from which the invention is based that is to say a connector with a housing (part) which is displaceable relative to the contact or to the connector carrier, this arrangement is not readily transferable. Because if one were to adopt the known arrangement as described in FR-A-2 562 338, the nose which constantly strives in the locking position when the conductor is inserted into the contact, the housing being in the position remote from the connector carrier, would get in the way and would consequently result in the assembly work and hinder the necessary relative movements of the parts. On the other hand, the known arrangement cannot ensure that the connection still acts reliably even in cases of special conductor stress in the sense of a conductor deflection outwards in the direction of the connector carrier.
  • the hook-shaped web In contrast, according to the invention it is possible to fold the hook-shaped web into the position corresponding to its later operative position relative to the conductor before the insulating housing part is brought into its end position. During this movement, the hook finally catches in the opening in the conductor and completes the tensile connection during the displacement of the insulating part. In its end position, the angled leg of the hook also ensures that the conductor is held securely even when turning sideways.
  • strain relief web does not (automatically) snap into a small opening in the final assignment of the conductor to the insulating housing, but already is folded into a slot-like opening in a pre-assembly position. This is the only way to achieve effective strain relief in a simple manner with a sliding insulating housing (part).
  • FR-A-2 562 338 makes no contribution to this teaching.
  • the electrical connector designated as a whole by 10, has an insulating material housing 11 and a number of contact elements 12 corresponding to the number of poles. As FIGS. 2 and 3 and 5 and 6 show, the contact elements 12 of the same type are arranged in parallel 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 near the connector carrier with respect to the contact element 12 (see FIG. 4).
  • Another locking recess 19 'on the fork leg 18 is used for the temporary locking of the connector carrier remote setting of the insulating material 11 with respect to the contact element 12 corresponding to FIG. 1st
  • 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 nose 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 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 conductor 27 is inserted with its stripped ends 26 through the conductor insertion openings 25 into the later clamping zone K.
  • the tab 30 is 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 overlap 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.
