Stamping mould for processing centre distance offset of needles in terminal

Abstract

The invention relates to a stamping mould, and aims to provide the stamping mould for processing centre distance offset of needles in a terminal. The stamping mould comprises an upper moulding board and a lower moulding board, wherein a bending region and a regulating region are sequentially arranged on the upper moulding board and the lower moulding board; a first bending assembly and a second bending assembly which are used for bending needle bodies are arranged in the bending region; the first bending assembly and the second bending assembly can separately bend the needle bodies in reversedirections; and a regulating assembly for regulating bending angles of the needle bodies is arranged in the regulating region. A to-be-stamped connecting sheet sequentially passes through the bendingregion and the regulating region, and the first bending assembly and the second bending assembly are utilized for pre-bending the needle bodies on the connecting sheet in two reverse directions in sequence, so that stress release is performed on the needle bodies by two times of bending positively and negatively; and bending angles of the needle bodies are regulated by the regulating assembly, sothat the needle bodies are gradually regulated to design positions, and therefore, precision of the centre distance of the two needle bodies is improved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for dealing with the deviation of the center distance of pins in a terminal. Background technique [0002] There is an existing connecting piece in a connector. The inner needles are two bent needle bodies punched on the connecting piece. A clamp is formed between the needle bodies, and the clamp is used to cooperate with the gold fingers on the male socket to realize electrical connection. The gold fingers on both sides of the male socket are arranged alternately, so the two pins need to be separated up and down by stamping. However, due to the existence of bending stress, the needle body may spring back after stamping and bending, which makes the center distance of the needle body deviate, and it is easy to have a mismatch between the jaw and the golden finger, which makes it difficult to assemble. Contents of the invention [0003] The purpose of the present invention is to ...
