A plug connector for direct electrical contacting of contact surfaces on a circuit board includes at least one electrical end contact of an electric line inserted into the plug connector housing in a plug-in direction and at least one separate electrical contact element, which protrudes elastically beyond one housing side of the plug connector housing transversely to the end contact for electrical contacting of a contact surface of the circuit board and is in electrically conductive contact with the end contact, at least when the contact surface has been contacted.

Plug connector for direct contacting on a circuit board

In a contact housing having a contact chamber for accommodating a contact body which can be inserted into the contact chamber through an assembly opening in a direction of insertion, in an operational position of the contact body in which it is stopped within the contact chamber, at least one element of contact chamber is lying against a stopping surface (support surface), of contact body, which generally points in a direction opposite to the insertion direction in such a way that the removal of the contact body is generally prevented counter to the insertion direction, the present invention provides that a center axis of the assembly opening has a lateral offset transversely to the direction of insertion with respect to a center axis of the stopped contact body; that in the contact chamber, in the direction of insertion, behind the assembly opening, a displaceably situated, elastically flexible spring is provided that extends into the path of the contact body, which narrows the path for the contact body and can be deflected by the contact body, and which is designed to be stressed in an assembly position during the insertion of the contact body.

Contact housing and electrical contact device

A contact housing for an electrical plug connection, having a plurality of contact chambers for accommodating in each case a contact element that is able to be plugged into the contact chamber through an assembly opening, having in each case a latching element, that extends laterally into the contact chamber, for the primary latching of the contact element which is pushed, up to its end position, into the contact chamber, and having in each case a locking element that is guided shiftably transversely to the plug-in direction of the contact element between two adjacent contact chambers, for the secondary locking of the contact element that is primarily latched in the one contact chamber, the locking element laterally extending into the one contact chamber using a locking projection in the locking position, and forming a guidance area of the other contact chamber on its side facing away from the locking projection. The guidance area of the locking element extends farther in the plug-in direction than the locking projection, and forms a contact area for a contact element that is primarily latched in the other contact chamber.

Contact housing for an electrical plug connection

In an electrical plug connector which includes an electrically conductive contact element having a plug accommodation provided for the insertion of a contact pin and having a contact lamella that laterally borders on the plug accommodation, as well as a leaf spring fastened to the contact element, which acts upon the contact lamella, the leaf spring is situated between the contact lamella and an outer wall of the contact element.

Electrical plug connector having an internal leaf spring

A contact housing for an electrical plug connector, having multiple contact chambers for receiving a respective contact body insertable through a placement opening into the contact chamber having, a respective elastically deflectable latching arm, protruding laterally into the contact chamber, for primary latching of the contact body inserted to its end position into the contact chamber, and having a respective locking element, displaceably guided transversely to the insertion direction of the contact body, that in its locked position protrudes, with a first locking projection, laterally into the contact chamber for secondary locking of the contact body latched in primary fashion therein. Provision is made that the locking element has a second locking projection that, in the locked position of the locking element, blocks the latching arm against deflection out of its position protruding into the contact chamber.

Contact housing for an electrical plug connector

An electric plug-in connector includes a plug receptacle provided for insertion of a contact pin, a contact lamina pivotally mounted on the plug-in connector housing, its free end being directed in the insertion direction of the contact pin, and a holding arm pivotably mounted on the plug-in connector housing, which protrudes at its free end into the plug receptacle in the ready-to-insert starting state of the plug-in connector and also holds back the contact lamina that is prestressed into the plug receptacle, the contact lamina and/or the opposite housing wall being made of an electrically conducting material for contacting the inserted contact pins.
