Cylindrical wire harness terminal and manufacturing method

Abstract

The invention discloses a cylindrical wire harness terminal and a manufacturing method, and the key points of the technical scheme are that the cylindrical wire harness terminal sequentially comprises an insertion and matching area, a crimping area and a blocking area which are connected into a whole and are made of alloy copper materials, and is characterized in that the insertion and matching area is buckled in a left-right manner to form a cylindrical shape; the side wall of the blocking area is higher than the insertion area to form a step-shaped side wall, the end face of the blocking area is an obliquely-arranged blocking end face, the blocking area is provided with a plurality of inverted-U-shaped limiting pieces cut along the blocking end face, the upper ends of the limiting pieces right face the insertion area, the lower ends of the limiting pieces are connected with the blocking area, a fixing piece is arranged outside the insertion area, and buckle structures are arranged at the head and the tail of the fixing piece. The buckles are connected to form a ring shape and fixedly wrap the insertion matching area. According to the invention, after the limiting sheet is formed by stamping, the limiting sheet relatively protrudes out of the insertion area, and when the fixing sheet is buckled and fixed outside the insertion area, the fixing sheet can be hung on the limiting sheet, so that the fixing sheet can be fixed on the insertion area more tightly, and the yield of products can be improved.

Description

technical field [0001] The invention relates to the technical field of connection terminals, more specifically, it relates to a cylindrical wire harness terminal. [0002] The present invention also relates to a method for manufacturing a terminal, including a stamping step and a forming step. Background technique [0003] The internal terminal of the car plug-in is a basic component of electrical design. After the plug-in is connected to the plug-in, it is finally connected by the male and female terminals in the plug-in to realize the transmission of current. The connection of the automobile wiring harness is realized through the engagement of the male terminal and the female terminal in the plug-in. The clamping of the wiring harness terminal is firm, so as to ensure the normal transmission of the current and finally realize the normal operation of the electrical device. The safe and reliable clamping of cylindrical wire harness terminals is an important content of autom...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that in the prior art, the wire harness terminal cannot be stably produced in large quantities for a long time in the one-time forming of rounding. The blocking area is produced by stamping deformation of the mold, and the mating area and the blocking area form a step. Shaped side walls, so that when the mold core is stamped and produced to a certain amount, the mold core will wear out quickly, resulting in poor stamping effect, and the end face of the blocking area is too inclined, which leads to the inability to hang the fixed piece and insert the product After matching, the fixing effect cannot meet the requirements, and defective products appear
