Abstract: A contact spring assembly for the self-locking contacting of a wire (28) of an electrical conductor includes a support wall (24) made of a conductive material and a contact spring (10). The contact spring (10) has a base leg (20) held stationary with respect to the support wall and a clamping leg (18) which, together with the support wall (24), forms an insertion receptacle (26) for the wire (28) of the conductor. The insertion receptacle is tapered in the insertion direction. The base leg (20) of the contact spring transitions into a holding leg (22? 22?), which is inserted into a receiving shaft (30) stationary with respect to the support wall (24) and has two detent projections (38), which protrude perpendicularly to the base leg in opposite directions and are locked to mating contours (34) on the walls of the receiving shaft.

Abstract: 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).

Abstract: 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.

Abstract: Disclosed is an overstretch prevention mechanism for a clamping spring (3) of a clamping spring-type contact device, the overstretch prevention mechanism consisting of a stop (21, 11) of an actuator (2) on a bus bar (1).

Abstract: Disclosed are a method for irreversibly connecting an electrical contact to an electrical conductor by way of a crimping apparatus operated under the effect of an external force, more particularly a crimping machine operated under the effect of an external force.

Abstract: Disclosed is a plug connector housing, which is formed from an at least partially open-pore, electrically conductive housing body, through at least part of which a non-conductive plastic material passes, and a plug connector that uses such a plug connector housing. Also disclosed is a method for producing a plug connector, wherein an open-pore, metal housing body is produced in a casting method or a sintering process, wherein the housing body is inserted in an injection molding tool, wherein in the injection molding process the outside of the housing body is encased with a plastic material at least in some regions, wherein plastic material also enters the open pores and the interior of the housing body.

Abstract: A plug connector housing is provided having at least two oppositely arranged locking pins protruding from the outside, wherein each locking pin includes a metallic component which is overmolded at least in some regions with a plastic material.

Abstract: A crimping device is provided for a conductor of a predefined cable to a predefined contact sleeve, having a crimp of a predefined crimp height, the crimping device has at least two suitable pressing elements that are mounted so as to be reversibly movable relative to a central crimping zone of the crimping device; for the proper operation of the pressing elements, the crimping device has a drive, the drive being operatively connected to the pressing elements via a mechanism; the drive being an electrically driven, substantially low-profile cylindrical coreless motor, and the pressing elements and the mechanism being arranged within the cylindrical motor. A controller for controlling the operation of the crimping device, a method for calibrating the crimping device, and a method for controlling the operation of the crimping device is also provided.

Abstract: A crimping tool for crimping a contact sleeve onto an electrical conductor of a cable has at least a cable transport device, a cutting and stripping device, a crimping device and a printing device, which are disposed one following the other in this order in a direction on a cable feed-through of the crimping tool with an axis. The crimping tool is designed such that a cable end of the cable, which cable end is inserted via a cable inlet opening of the cable feed-through, is fed by the cable transport device in the direction to the cutting and stripping device, to the crimping device and to the printing device and subsequently is led out of the crimping tool via a cable outlet opening of the cable feed-through, which cable outlet opening is opposite the cable inlet opening.
