Definitions

• the present invention relates to a connector for connecting two conductors.
• the invention particularly relates to a connector for connecting two flexible flat conductors. It is used wherever two conductors have to be interconnected with one another, for example in the automotive industry or in computer technology.
• connection area for the detachable connection of two ribbon conductors, one conductor being wound around springs provided in the housing with contact arches and pressed onto the conductor tracks of the other conductor with the contact arches.
• attaching the first conductor in the connection area is complicated and time-consuming.
• the object of the present invention is therefore to provide a simply constructed and easy-to-operate plug connector with which conductors, in particular ribbon conductors, can be connected to one another in a simple manner.
• the connector for connecting two conductors has a first housing half, a second housing half, which can be locked in a final locking position by a pre-latching division with the first housing half, and an electrically conductive clip which contacts the two conductors in the final locking position and electrically connects them to one another.
• housing half does not limit the geometric shape in half. Rather, each half can have any shape.
• the conductors used are preferably flexible ribbon conductors. These usually have a plurality of conductor tracks running parallel to one another on a non-conductive, flexible base.
• the clip is U-shaped, the two legs of the U-shaped clip each contacting at least one conductor in their final locking position.
• the connecting plate of the two legs of the clip is preferably arranged in one of the two housing halves.
• the clip is preferably arranged in a recess in one of the two housing halves, the other housing half having a shoulder which, in the final locking position, presses the conductor into the recess between the two legs of the clip.
• actuation of the second housing half presses it from the pre-locking position into the final locking position in the direction of the first housing half, as a result of which the conductor is pushed onto the clip through the shoulder formed on the other housing half.
• the conductors are pressed onto the legs.
• Each leg preferably has a recess or an incision into which the conductor or conductors are pressed.
• the conductor ends to be connected can be stripped, but they can also be pressed with an insulator onto the recess or the cut on each leg.
• the legs can be designed at their contact point in the incision in such a way that they cut through an insulating jacket of the conductor, so that a prior removal of the insulating jacket is not necessary.
• one housing half can have a rib which presses one of the two conductors into a recess formed on the other housing half in the final latching position, as a result of which a strain relief for the conductor is formed.
• Each housing half preferably has a rib and a depression, the rib of each housing having one Presses the conductor into the recess of the other housing, whereby a strain relief is formed for both conductors to be connected.
• the rib formed on the housing halves can form a stop for the two conductors which are inserted into the connector on opposite sides of the connector.
• the two conductors can be inserted into the plug connector to such an extent that they overlap over the clip and that each leg of the clip contacts both conductors in the final locking position.
• the conductors can only be inserted into the connector to such an extent that the conductors do not overlap above the clamp and each leg of the clamp contacts only one conductor.
• the one housing half can also be formed in two parts, each part of this housing half being able to be locked individually with the other housing half in the final locking position.
• each part of the two-part housing half can preferably press a conductor onto one leg of the clip.
• each conductor can be connected to the clamp independently of the other conductor by pressing the part of the housing half lying above the limb of the clamp in the final latching position.
• Each leg of the clip preferably has an incision in which at least one conductor is clamped in the final locking position. Depending on whether the two conductors are above the Overlapping the clamp, either one or two conductors are clamped in each leg of the clamp.
• the leg can also have two opposite clamp arms which are separated from one another by an incision.
• the clamp is an insulation displacement clamp, so that the contact conductor pressed into the leg of the clamp is clamped and any insulation that may be present is cut open, so that the clamp contacts the conductor directly.
• the plug connector can have cutting devices which, in the case of a conductor with a plurality of conductor tracks, separate these from one another when the second housing half is locked in the final locking position. This ensures that the conductor as a whole, with its insulation lying between the conductor tracks, is destroyed when the conductor tracks are pressed onto the limbs of the clip.
