Embodiments of the disclosure reduce the complexity required to mechanically connect at least two printed circuit board plug connectors together in a reversible manner. This is achieved by a device which has at least one introduction opening for introducing at least one coupling element in an introduction direction. The device additionally has at least two insertion openings for inserting at least two printed circuit board plug connectors in an insertion direction, wherein each of the two insertion openings is connected to the aforementioned introduction opening in order to allow a mechanical fixation of the coupling element to each of the two printed circuit board plug connectors.

A high-performance connector for receiving at least one electrical cable has a contact holder for fixing a contact element connected to the cable in place in an insulating body, wherein the contact holder has an at least essentially hollow-cylindrical main body on which at least two contact arms are arranged, and wherein the contact arms are configured to form, starting from the main body, a diameter which decreases in a direction away from the main body.

A locking device for line connectors includes a first housing ( 10 ) and a second housing ( 12 ) that can be placed against one another in an engagement direction (A). A set of resilient locking tabs ( 26 ) are held on the first housing ( 10 ) by fastening elements and can be latchingly locked on locking projections ( 32 ) of the second housing ( 12 ). A release ring ( 38 ) can be slid on the housings ( 10, 12 ) in the engagement direction (A) and that has release slopes ( 42 ) for transferring the locking tabs ( 26 ) into a released position. The fastening elements and the locking projections ( 32 ) are in the form of pins ( 24, 34 ) that are set in peripheral walls of the two housings ( 10, 12 ).

A single-pole connector is provided that includes a contact, which includes a contact housing; and a hood for receiving the contact; wherein the contact housing is provided with a limiting frame on the outer surface, wherein the limiting frame is provided with at least two limiting tongues; wherein the hood has at least two limiting recesses and a female threaded portion on the inner surface, wherein the female threaded portion is closer to the mating face than the limiting recess; wherein the single-pole connector further includes a retaining ring having a male threaded portion, wherein after inserting the contact housing into the hood counter to the plug-in direction until the limiting tongue is inserted into the limiting recess, the retaining ring is screwed into the hood, whereby the contact housing is fixed in the hood by a screw connection. A multiple plug-type connector and a connector system is also provided. A simple fastening of the contact can be achieved with the single-pole connector and the multiple plug-type connector. Independent installing or removal of the single-pole connector can be achieved with the connector system, thus facilitating assembly.

A plug connector is provided having a plug-in side, a connection side, and a plug-in direction, which extends from the connection side to the plug-in side, towards a mating connector or a socket, the plug connector having a contact insert and at least four contact elements, the contact elements being positioned in the contact insert in dedicated receiving regions, the plug connector having at least two bridging elements for the electrical connection of in each case at least two contact elements, the bridging elements being positioned one behind the other as viewed in the plug-in direction.

An insert for a connector, said insert is provided having: an insert housing, a cavity of the insert housing having a plurality of connection accommodating holes for accommodating a plurality of connections, and the plurality of connections comprising at least one protective earthing connection; and a protective earthing plate which is attached to the outer surface of the insert housing in order to electrically contact the protective earthing connection. The insert can accommodate more connections, thereby providing a high-density connector; moreover, it is possible to use power connections and protective earthing connections of the same type in order to allow for quick assembly and disassembly, and customers can replace the connections according to actual use.

A contact spring arrangement includes a carrier structure which has a support wall made of a conductive material. A contact spring has a base limb, held in a fixed position with respect to the support wall, and a clamping limb which, together with the support wall, forms a plug socket narrowing in the insertion direction for a core of an electrical conductor. A release member is guided displaceably in a guide body in the insertion direction with respect to the support wall and has an actuation arm which, in a release position, engages on a flank of the clamping limb facing towards the plug socket and holds the clamping limb, counter to the spring force, in a position bent back towards the base limb. The carrier structure forms a stop which limits the range of movement of the release member in the insertion direction.

An insulating element for a high-power plug connector system comprises at least one stop formation for limiting the distance of insertion into the high-power plug connector system and at least one cutout, which allows contact to be established between a receivable high-power contact and at least one electrically conductive bar. The insulating element has at least one retaining formation, which is located on the periphery of the insulating element, near the stop formation.

An assembly of a plug-in connector component, and a plug-in connector component and system are disclosed. The assembly of a plug-in connector component includes: an insulator, the insulator including: a plug-in section, which can be plug-connected in a plug-in direction with a mating plug-in section of an insulator of an assembly of a mating plug-in connector component; and a grounding element mounting section, the grounding element mounting section extending from the plug-in section in a direction opposite to the plug-in direction; a grounding element, mounted in the grounding element mounting section and including grounding element body and a housing contact portion provided at an end of the grounding element body; and a contact piece, including contact piece mounting portion and a contact extending from the contact piece mounting portion in the plug-in direction, the contact piece mounting portion mounting the contact piece to the insulator.

An insert for a connector is provided having: an insert housing, wherein a cavity of the insert housing has multiple connection-accommodating holes for accommodating multiple connections, and wherein the multiple connections comprise at least one protective grounding connection; a holding plate, which is attached to a connection side of the insert housing in order to hold the multiple connections in the cavity; and a protective grounding plate, which serves for electrical contact with the protective grounding connection. The insert can accommodate more connections, whereby a high-density connector is provided, wherein power connections and protective grounding connections of the same type can be used in order for quick assembly and disassembly to be realized, whereby it is also possible for customers to replace the connections according to actual use.
