AI Technical Summary

Problems solved by technology

Crimps have been shown to lose their effectiveness due to the elastic spring-back phenomenon of the crimp tabs, which reduces the terminal pressure between the tabs and the crimped wire strands and can lead to increased terminal impedance or Causes instability and even loss of electrical contact and continuity

Embodiment Construction

[0034] according to figure 2 In the illustrated example of application, a crimping process is performed on an electrical terminal with an open bobbin. The terminals include:

[0035] - the front part A, which is specially designed for coupling with typical complementary terminals;

[0036] - crimping part 30, which is located in the middle part and is provided with an open bobbin 3 with tabs 4, 5 for crimping on the stripped part 12 of the wire 2, crimping The portion 30 is designed to be crimped on the wire to establish electrical contact between the wire 2 and the terminal element 1 .

[0037] According to this embodiment, the terminal element 1 has a terminal part 31 formed with a suction or pressure relief zone provided with tabs 10 , 11 designed to close over the insulating sheath 13 of the wire 2 .

[0038] The front part A of the terminal element can be of any type and can even be made of a second crimp, for example to form a splice.

[0039] The terminal element i...

Abstract

A method of crimping an electrical terminal onto a wire, comprises: providing an assembly comprising a wire and an electrical terminal, applying an initial crimping step, by folding an initial part of the crimping section (30) over the stripped part (12) of the wire, applying a subsequent crimping step, by compressing a subsequent part of the crimping section over the stripped part of the wire.

Description

technical field [0001] The invention relates to a method of crimping electrical terminals and components obtained by the method. Background technique [0002] It is known how to establish an electrical fit between an electric wire (especially stranded wire) and a metal terminal element by means of a crimping operation in which the metal terminal element is cut from the metal terminal element by means of a crimping tool of the stamp-anvil type. The exiting tabs are bent around the stripped wires. This technique is applied to terminals made from metal blanks that have been cut and bent. [0003] For example, US Patent No. 5,561,267 discloses a terminal to be crimped and a method of crimping using a special molded anvil tool, the terminal including tabs of different sizes to allow one crimping tab to overlap another. [0004] Crimp terminals suffer from reliability issues in low current and low voltage applications, more specifically the development of microcracks over time. ...
