Definitions

  • the invention relates to a connector, in particular for the detachable connection of electrical conductors, with a plug part each comprising an insulating housing and a coupling part, one of which is provided with at least one receptacle for connecting at least one conductor, in particular in the form of a ribbon cable, and essentially without force with the other connector part can be plugged together and pivoted there into a coupling end position, in which contact surfaces assigned to the first connector part come into conductive connection with the second connector part associated contact surfaces.
  • the first connector part designed as a plug part is designed as a so-called insulation displacement connector.
  • Its insulating material housing is in two parts. In one part, a number of metallic contacts corresponding to the number of lines are embedded, the rear ends of which form cutting edges for contacting clamping of the conductors.
  • the second insulating part is designed as a cover which can be latched to the first insulating part, with the aid of which the conductors are press-fitly clamped into the contacts when they are placed on the other insulating part, while their insulation is severed.
  • the second connector part has fork-shaped contact elements with solder pins attached to it Fixing this connector part on a circuit board.
  • the first connector part In order to establish the connection between the connector parts, the first connector part is inserted in an inclined arrangement into a receptacle of the second connector part until the electrical contacts arranged on the front side of the first connector part plunge force-free into the area of the counter contacts arranged in the second connector part.
  • the first connector part with the line attached to it is then pivoted through an angle of approximately 250 until it engages in a defined coupling end position.
  • the connection is now mechanically and electrically fixed.
  • the first connector part with the line attached to it can also be removed from the second connector part by pivoting it back and then pulling it out without force.
  • the known connector system which is also offered in a similar form by other manufacturers, is very advantageous.
  • the invention is based on the object of significantly simplifying such a connector, in particular with regard to the first connector part.
  • the invention solves this problem in that the at least one receptacle of the first connector part is at least partially open in the area of assignment to the contact surfaces of the second connector part and that each conductor itself forms the contact area assigned to the first connector part.
  • the connector part in contrast to the prior art, no metallic contact elements are provided in the first connector part, so that this connector part can consist exclusively of a one-piece and one-piece injection-molded body made of insulating material, in particular plastic.
  • An essential aspect of the invention is to partially open the connector part in order to enable the contacts arranged in the second connector part to make direct contact with the bare conductors or stripped conductor ends accommodated in the first connector part.
  • the invention makes a considerable contribution to simplifying the first connector part. Because not only its shape is considerably simplified, the equipping with the conductor or several conductors is less complicated to carry out and therefore requires only relatively simple assembly devices. Basically, the conductor (s) only need to be plugged into the relevant receptacle (s) of the first connector part. This can be done in the case of pre-assembly by carrying out this connection before the first connector part is coupled as intended with the second connector part. It is also readily possible to first insert the first connector part into the second connector part in the preassembly position, then at least the one insert a conductor into the first connector part and finally pivot the latter into the end position.
  • the first connector part has an approximately sleeve-shaped, essentially closed-walled receiving space for the conductor insulation sheathing and, in the plug-in direction, axially partially open receiving chambers for the stripped conductor ends.
  • the sleeve-shaped receiving space fixes the conductor or conductors, while the partially open receiving chamber holds its stripped end in the correct position, but allows the contact elements of the second connector part to have electrically conductive access through the partial opening. It is essential that the bare conductors do not need to be bent or bent over in order to be able to come into contact with the contact elements of the second connector part.
  • the contact elements of the second connector part are usually fork-shaped and contact with their two legs the conductor located in the first connector part, it is advantageous if the windows of the partially open receiving chambers are arranged both in the conductor direction and diametrically offset from one another. As a result of the offset arrangement, there is therefore a support surface for the conductor and for absorbing the contact forces in each contact area on the side of the conductor facing away from the window.
  • an alternative embodiment provides that the partially open receiving chambers have windows that run axially, ie parallel to the conductor, and whose gap width is smaller than the conductor diameter. This version does not require a length offset of the windows, because here the window edges securely support the conductor against the contact forces.
  • the connector according to the invention can also be used for connecting foil conductors printed with conductor tracks, a preferred embodiment being characterized in that the first connector part has an approximately sleeve-shaped, essentially closed-walled guide for a ribbon cable and, in the plug-in direction, a supporting wall section for the rear thereafter of the ribbon cable.
  • the particularly favorable connection of a conductor or a cable to the first connector part is ensured if the first connector part is provided with tension-relieving, clamping or form-fitting means for attacking the conductor or the line, whereby the first connector part can be provided with tension-relieving hooks for engaging in openings arranged between conductors of a ribbon cable, and it is in turn advantageous if the hooks protrude into the insertion path of the ribbon cable in such a way that the positive connection when the ribbon cable is inserted into the first connector part Coupling of the breakthroughs is done automatically with the hook.
  • the line and the first connector part can be connected to one another by means of pre-assembly. Without further ado, it is also possible to either plug the first connector part together with the line and then couple this unit with the second connector part or insert the first connector part into the second connector part, then insert the line and connect it to the first Swivel the connector part together into the position of use.
  • the strain relief is in any case effective the first time a line is connected to the first connector part.
  • a connector consists of a first connector part 10 and a second connector part 11.
  • the connector part 11 has, in an insulating body 12, a number of fork-shaped contact elements with the contact legs 14 and 15 which corresponds to the number of lines 13 to be connected to be contacted with a conductive section 16 of the line 13.
  • the first connector part 10 consists of an insulating body 17 which is injection-molded in one piece and in one piece from plastic. It is subdivided into essentially two sections 18 and 19, section 18 forming an essentially sleeve-shaped, closed-walled receiving space 20 for the end section of conductor 13 provided with insulating jacket 21, and section 19 serving to receive conductor ends 16. Openings 22 are provided in the bottom of the receiving space 20 for the passage of the stripped conductor ends 16, so that these can enter the front section 19 of the connector part 10, in a straight, unbent manner.
  • This section 19 has - corresponding to the opposing contact legs 14 and 15 of the second connector part - diametrically opposite windows 23, 24.
  • these windows 23, 24 are shown as running over the axial length of section 19 of the first connector part 10. So that the resilient contact legs 14 and 15 cannot push the conductor out of its receptacle within this section 19, the window width here is smaller than the diameter of the stripped conductor end 16.
  • the windows 23 and 24 are wider, but offset in the longitudinal direction of the conductor (FIG. 4b), so that each contact leg 14 or 15 finds an abutment section 25 on the side facing away from the stripped conductor end 16.
  • FIGS. 1 and 4 there are hooks 26 within the section 18 of the first connector part 10, which protrude into the insertion path of the conductor 13 and are intended to form a positive connection with openings 27 which are in between the conductors of the ribbon cable 13 as shown in Fig. 1 are arranged.
  • the arrangement is such that the hooks 26 are arranged with respect to the insertion path of the ribbon cable 13 so that the positive coupling takes place automatically when the line 13 is inserted into the first connector part 10.
  • the unequipped first connector part 10 is inserted in an inclined position into a receiving space intended for this purpose within the second connector part 11 (FIG. 2).
  • the contact legs 14 and 15 do not yet dip so far into the section 19 of the first connector part 10 that the conductor 16 could be touched. Therefore, the line 13 with the stripped conductor end 16 can be inserted force-free into the first connector part 10, the stripped ends 16 not touching the contact legs 14 and 15.
  • the first connector part 10 with the conductor 13 accommodated therein is given counterclockwise with respect to FIG.
  • the exemplary embodiment according to FIGS. 5a to 5d differs from the exemplary embodiment explained first in principle in that a flexible film 30 printed with conductor tracks 29 is used as the conductor 13 and in that the structural design of the first connector part 10 is adapted to it.
  • side walls 32 and an end wall 33 are formed on the wall 31, so that the section 19 is partially open to one side and a type of window 34 is also formed here.
  • the substantially sleeve-shaped sections 18 of the connector part designs described serve, as mentioned, to guide the conductor 13, but additionally also as a handle body for handling this connector part 10.
