Abstract: The invention proposes an electrical plug-type connector for making contact with a mating plug-type connector, said plug-type connector having a displaceable locking and unlocking apparatus, which exerts a constant pressure on the apparatus by means of a double-sided torsion spring in such a way that the plug-type connector is forcibly locked when contact is made between said plug-type connector and the mating plug. In this case, the pressure exerted by the torsion spring legs is transferred to two axially displaceable sliding posts, which are again part of the unlocking apparatus. Furthermore, the unlocking apparatus has two sliding arms, which can be displaced in a tongue-and-groove guide, at least in regions, within corresponding recesses and flush with respect to the side faces of the plug-type connector housing.

Abstract: To compensate the lateral offset of an opposing plug, a contact element for a plug-in connector socket has particularly large tolerances. For this purpose, the contact element is embodied in two pieces, a contact spring element for making electrical contact with the opposing plug and a securing element in which the contact spring element is mounted so as to be rotatable about a rotational axis. In contrast to a case in which tolerances depend on deformation of a spring element, by virtue of rotation of the contact spring element no forces act on the soldering points with which the securing element is soldered to a printed circuit board. The contact element is particularly suitable for soldering according to SMT.

The insulating body is held on guide of the housing in a rotatable manner and in an insertable manner into the housing via an opening. The guide can be formed as slits that lie in lateral parts of the housing. The lateral parts project beyond the housing. Electric conductors can be inserted into the insulating body on a rear surface, plugged through said body, and cut on a front surface. The electric conductors are thus brought to the intended length before the insulating body is inserted into the housing.

The contact arms are arranged essentially pointing in the opposite direction to the insertion direction of the mating contact running toward one another, and curving away from one another on their free standing end areas. The contact spring has at least one first solder connection which is integrally formed directly on the bridge and faces in the opposite direction to the insertion direction of the mating contact.

Abstract: In order to simplify the assembly of printed board connectors, there is provided an assembly aid that features one or more recesses in accordance with the dimensions of the printed board connectors, wherein one or more printed board connectors to be assembled on a printed board can be inserted into said recesses.

The assembly aid remains on the printed board until the soldering process is completed, wherein this prevents, for example, flotation of SMD components.
