Embodiment Construction

[0022] according to figure 2 Application example shown in , crimping on an electrical contact with an open barrel. This contact comprises a front part A, in particular intended to be joined to a conventionally known complementary contact, which also has a crimping part 30 at the middle part which is joined by crimping, the crimping part There is an open barrel 3 equipped with wings 4, 5 for crimping onto a stripped part 12 of an electrical wire 2 designed to be crimped onto the electrical wire to provide a connection between the electrical wire 2 and the contact element 1. electrical contact between them.

[0023] According to this example, the contact 1 has an end portion 31 forming a force-absorbing area provided with wings 10 , 11 designed to close onto the insulation 13 of the wire 2 .

[0024] The front part A of the contact can be of any type, and can even consist, for example, of a second part joined by crimping to form a joint.

[0025] The contact is made by cutti...

Abstract

The invention relates to a method of crimping an electrical contact on an electric wire, said contact comprising a crimping portion provided with a barrel (3) for receiving an electric wire (2), said barrel comprising a And clamp the part of the wire. The method comprises a first crimping step performed at a first crimping height (h1) and a second crimping step by means of a crimping tool comprising a crimping element (6) and an anvil (7) While the first surface of the crimping portion is folded over the wire (2), the second crimping step is at a second crimping height (h2) lower than the first crimping height at the crimping Execute in the local area of ​​the connected part. The invention also relates to a contact obtained according to said method.

Description

technical field [0001] The invention relates to a method of crimping electrical contacts and a contact obtained by the method. Background technique [0002] It is known how to make an electrical contact, in particular between wires of a multi-wire harness, and metal contacts by a crimping operation in which the metal contact is cut by a crimping tool of the punch-anvil type. The resulting wings are bent around the stripped wires. The technology is applied to contacts made from metal blanks that have already been cut and bent. [0003] Document US 5,561,267 for example relates to a contact to be crimped and a method of crimping by means of a specially designed punch-anvil tool, the contact comprising wings of different sizes to allow one crimping wing to be overlaid on the other . [0004] Crimped contacts suffer from reliability problems in low current and low voltage applications, more specifically the development of microcracks over time. The effectiveness of the crimp...
