Preparation technology of harpoon-shaped terminal for connector

Abstract

The invention relates to a preparation technology of a harpoon-shaped terminal for a connector. The preparation technology comprises the following steps that S1, a strip-shaped raw material plate is selected, and the raw material plate is placed at the starting position of a punching machine; S2, positioning holes are formed in the both sides of the raw material plate by punching, and excess edgematerials on the raw material plate are cut off; S3, the rod portion of the harpoon-shaped terminal is punched out, and a rectangular outline of the terminal is punched out through a rectangular framemold; S4, a hollowed-out area of the end part of the harpoon-shaped terminal and a concave arc-shaped area of the terminal are punched out; S5, a high-speed continuous die is used for precision-punching to form a 0.10-0.14mm terminal gap; S6, the end portion and the rod portion are chamfered, the edges of the end portion and the rod portion are removed; and S7, precision blanking are carried outto obtain a finished product of the harpoon-shaped terminal. Compared with the prior art, a set of technology for preparing novel harpoon-shaped terminals is designed, and novel harpoon-shaped terminals for the connectors with excellent mechanical properties and high yield of the finished products are obtained.

Description

technical field [0001] The invention relates to a preparation process of a connector part, in particular to a preparation process of a harpoon-shaped terminal of a connector. Background technique [0002] With the replacement of connectors, the connectors used in the automotive industry and the communication electronics industry are getting smaller and higher, and the requirements are getting higher and higher, especially the connector terminals. The terminals mainly play the role of clamping and mating ends. The size is generally 0.30-0.35 mm or more, and when a new type of harpoon terminal is used, the terminal size of 0.10-0.14 mm can be achieved through structural design. Because when the terminal is used as the working surface, its advantages and disadvantages mainly depend on the specific punching process. For the existing production technology, punching the terminal is a relatively complicated industrial process. The terminal is required to be smooth, and the thicknes...

Problems solved by technology

Because when the terminal is used as the working surface, its advantages and disadvantages mainly depend on the specific punching process. For the existing production technology, punching the terminal is a relatively complicated industrial process. The terminal is required to be smooth, and the thickness of the material T = 0.3mm or below, the general terminal size is above 0.35mm, and the new type of terminal is especially aimed at the material thickness T=0.6mm or above, the terminal size is 0.14mm or below, because there is no reasonable process to make the processing process difficult, the finished product The yield rate is very low, so in order to realize the mass production of this new type of harpoon terminal, it is necessary to design a set of reasonable stamping process methods
