Embodiment Construction

[0045] Figure 1a-Figure 1b In isometric diagram ( Figure 1a ) and cross-sectional view (Figure lb) shows an embodiment of the contact element.

[0046] The contact element 2 comprises an electrical conductor 4 which is sheathed with a conductor insulation 6 of relatively soft polyurethane having a Shore A hardness of 80. The end 8 of the conductor 4 is stripped of the insulation and welded by means of ultrasonic waves (in Figure 1b ) is connected in an electrically conductive manner to the connection region 9 of the cable gland 10 . The cable gland 10 has a flat ring-shaped contact piece 11 with a central hole 12 and a plurality of smaller openings 13 arranged around it.

[0047] The cable connection 10 and the section 14 of the electrical conductor 4 connected thereto are injection-moulded with an electrically insulating jacket 16 made of polyurethane, the part 17 of the contact piece 11 having the hole 12 being exposed.

[0048] The housing 16 forms a first socket 18 h...

Abstract

The invention relates to a contact element (2) for electrically interconnecting an electrical conductor (4) and a connection part (40) of an electrical system (42), in particular an electrical system of a motor vehicle, said contact element comprising the electrical conductor (4), which is sheathed with conductor insulation (6), and comprising a cable lug (10, 10', 10", 10"') electrically conductively connected to the electrical conductor (4) and having a contact part (11), the cable lug (10, 10', 10", 10'") and an adjoining portion (14) of the electrical conductor (4) being jacketed with an electrically insulating sheathing (16) such that one part (17) of the contact part (11) remains exposed, the sheathing (16) having a passage (20, 26) running from an opening (22, 28) of the sheathing (16) to the exposed part (17) of the contact part (11), and a sealing element (30) for sealing a closure (44, 34), in particular a cover (34), which can be used to close the opening (22, 28), being injection-moulded onto the sheathing (16). The invention also relates to a method for producing a contact element (2) of this type.

Description

technical field [0001] The invention relates to a contact element for electrically contacting an electrical conductor to a connection part of an electrical installation, in particular an electrical installation of a motor vehicle, the contact element having an electrical conductor which is enclosed by a conductor insulation and having Cable gland electrically conductively connected to an electrical conductor, the cable gland having a contact piece, wherein the cable gland and the section of the electrical conductor connected to the cable gland are injection-molded with an electrically insulating sheath in such a way that A portion of the contact is exposed, and wherein the housing has a channel extending from the opening of the housing to the exposed portion of the contact. Such a contact element can be used, for example, to produce a watertight screw contact between an electrical conductor and a connection part of an electrical installation. Background technique [0002] I...
