A sleeve (11) is a hollow cylindrical member provided in a shield terminal (10), and pressable by a wire barrel (18) by being arranged between an insulating portion (63) and a shield portion (62) of a shielded cable (60). A convex portion (36) shaped to bulge radially outward over an entire circumference is provided at an intermediate position of the sleeve (11) in an axial direction. The convex portion (36) is crushed and elongated by the wire barrel (18) of an outer conductor terminal (13). The insulating portion (63) can be prevented from being excessively compressed.

An electrical terminal includes a contact portion that is adapted to engage a complementary contact and is connected to a transition portion. The electrical terminal also includes a crimp portion. The crimp portion includes a crimp base that extends in a first crimp direction from the transition portion to a base end. Two first crimp wings are located on opposite sides of the crimp base and extend in a second crimp direction. The first crimp wings are separated from each other by a width. Two second crimp wings are also located on opposite sides of the crimp base and extend in the second crimp direction. The second crimp wings are also separated from each other by the width.

A gas sensor includes a sensing element that includes an electrode pad, a metal terminal, and a separator. The metal terminal includes a lead-wire-connecting portion, a main body, a protruding piece that protrudes from a front-end side, and an elastic portion connected to an end of the protruding piece and to the electrode pad. An area S1 of a first opposed surface of a primary surface facing an insertion hole of the separator is larger than an area S2 of a second opposed surface of a secondary surface facing the insertion hole, and a part of the second opposed surface contacts an inner circumferential surface of the separator forming the insertion hole, and the first opposed surface is separated from the inner circumferential surface, where surfaces of the main body and the protruding piece that are located opposite the elastic portion are the primary surface and the secondary surface.

The electric energy transmission joint includes an electric energy transmission copper part, an electric energy transmission aluminum part (9), and an aluminum wire (3). The electric energy transmission copper part includes a fixer (1) for connection with an electric consumption device, and a connector (2) for connection with the electric energy transmission aluminum part (9). A first through hole is provided inside the electric energy transmission aluminum part (9), and a second through hole is provided inside the connector (2). An aluminum conductive core (4) exposed by stripping an insulation layer (5) from a front end of the aluminum wire (3) is inserted into a cavity formed by the connection of the first through hole and the second through hole. The electric energy transmission aluminum part (9) is connected to the aluminum wire (3) by crimping. The electric energy transmission copper part has the advantages of light weight, fast production, and reduced production cost.

Prior to insertion into the recess of a crimping region, the axial ends of the plurality of electrical strands of the cable are fixed with a clamping tool so that the axial ends of the plurality of electrical strands protrude axially out of the clamping tool and the ends of the plurality of strands protruding axially from the clamping tool are sheared off in the transverse direction with a cutting tool so that a closed end face is produced at the axial end of the strands. The axial end of the plurality of electrical strands is inserted into the recess and the plurality of strands are welded to the contact piece by melting the closed end face arranged in the recess by radiation energy of a radiation directed onto the end face.

The invention relates to a method for manufacturing an electric cable (2), according to which the cable (2) is successively processed in processing modules (41, 43) that are independent from one another. According to the invention, at least one sheath clamp (10.1, 10.2, 10.3, 10.4), which is independent from the plug connectors (22) that are to be mounted on the cable (2) during manufacturing, is attached to a cable sheath (9) of the cable (2) in a non-positive fit at a defined axial position along the longitudinal axis (L) of the cable (2). Alternatively or in addition, the cable (2) is attached to a cable carrier (4), wherein the cable carrier (4) comprises at least one stop element (44) which is arranged at a defined axial position along the longitudinal axis (L) of the cable (2).

A method for assembling a cable connector which has an outer conductor part, and insulating part and an electrical cable that is prefabricated with an inner conductor part. In a first method step, the insulating part is introduced into the outer conductor part by relative movement between the insulating part and the outer conductor part. In a second method step, before or at least partially during the first method step, the electrical cable is prefabricated to have an inner conductor part secured on an inner conductor of the cable. In a third method step, during or after the first method step, the prefabricated cable is introduced into the insulating part up to a defined axial terminal position. The positions of the inner conductor part, the outer conductor part and/or the insulating part are fixed relative to each other by compressing the outer conductor part at least partly.
