Terminal plugging mechanism of automatic assembling machine of electric connector

Abstract

The invention discloses a terminal plugging mechanism of an automatic assembling machine of an electric connector, which comprises a base and a terminal locating base, wherein the terminal locating base is provided with a baiting groove and a terminal groove; the front end of the terminal groove is provided with bosses which abutted against a terminal sticking point and have difference lengths; a plastic cement piece locating base, a terminal feeding rail, a lifting block, a pressure terminal sliding cover and a plunger pin are arranged around the terminal locating base; drive devices are arranged directly at the plastic cement locating base, the lifting block, the pressure terminal sliding cover and the plunger pin; therefore, the lifting block, the pressure terminal sliding cover and the plunger pin are utilized so as to cut a terminal material belt; and sliding of the plastic cement piece locating base and the bosses which are arranged on the front end of the terminal groove and the have different lengths are utilized so as to plug the terminal according to a predetermined length. According to the invention, a traditional manually terminal plugging method is substituted, thus, product production efficiency is increased, human resource consumption is reduced, operation personnel workload is reduced; relative potential safety hazard probability is low; in addition, reject ratio of the electric connector can be also reduced; the terminal plugging mechanism disclosed by the invention is suitable for large-scale manufacture and production; and enterprise competitive power is enhanced.

Description

technical field [0001] The invention relates to the technical field of an automatic assembly machine for electrical connectors, in particular to a terminal insertion mechanism for an automatic assembly machine for electrical connectors. Background technique [0002] Electrical connectors are generally composed of three parts: plastic parts, terminals and metal housings, so the assembly of electrical connectors is to assemble the plastic parts, terminals and metal housings according to the determined relationship between the three. At present, the assembly of electrical connectors is generally carried out by manual or semi-automatic machines, and the process is relatively complicated. The main process steps include: [0003] First, the terminal is cut into a single PIN, and the terminal is pre-inserted into the plastic part manually, and then put into a manual punching fixture or a semi-automatic machine for riveting and fixing; then, the terminal strip is broken by hand; fin...
