Description

Connector manufacturing method

The invention provides a method for manufacturing a connector, in particular, a plurality of terminals on a single tape having a first contact end and a second contact end with different pitches, and the socket can be matched with the socket of the input end and the output end of the connector. Positional deviation requirements, and can effectively save the labor and cost of production.

Press, the general connector is the connecting component used in the electronic signal and the power supply and its accessory accessories. The main function is to provide bridging between various products and ensure the accurate transmission of the message, but the connector with the application object, frequency, power Different from the application environment, there are various forms and structures, and can be applied to computers, computer peripherals or industrial equipment, telecommunications and communications, automobiles, transportation, household appliances, medical products, etc., and also the predetermined functions of circuits in electronic products. Indispensable parts.

Furthermore, the general connector refers only to the metal component and the plastic component or the connector of the metal component only, wherein the metal component is mainly composed of the terminal and the outer casing, and the terminal is a key component of the connector to complete the electrical connection function, generally The contact pair is formed by the conductive terminal and the contact terminal, and the electrical connection is completed by inserting, and the conductive terminal is cylindrical (round pin), square column (square pin) or flat (tab), and The contact terminal is a jack, and is elastically deformed by the elastic structure to form a close contact when being inserted into the conductive terminal, and the jack structure is various, such as a cylindrical type (groove, ablation), a tuning fork type, Cantilever type Longitudinally slotted), folded (longitudinally slotted, 9-shaped), box-shaped (square) and double-curved wire spring jacks.

However, the input end and the output end of each terminal in the connector are mostly of the same pitch design, and the input end and the output end of the terminal are in the same position, if the terminal in the same connector product requires two kinds of pitches. For example, if the positions of the sockets on the upper and lower terminals of the connector are different, it may be necessary to use separate tape connection terminals to make separate or separate tapes and use discrete terminals (distributed pins). For the production, if the mold is compared with four holes, the four pairs of eight sets of three opposite discrete terminals need to be placed a total of twenty-four times, resulting in the labor hours of the multiple terminals placed in the mold. Compared with the cost, the overall structure is also unstable, so that each terminal needs to design fixed parts, which leads to the complexity of the mold design, the difficulty of increasing the complexity and the cost, and the redesign of the industry. To solve it effectively.

Therefore, the inventors have designed and developed such connectors because of the inadequacy and lack of use of the conventional connectors, and the collection of relevant materials through various evaluations and considerations, and the continuous trial and modification of the years of research and development experience in the industry. The manufacturing method invention patent was born.

The positional requirement and the way of placing the strip compared to the dispersing terminal can effectively save man-hours and costs, thereby achieving the effects of stable structure, simple assembly and low cost.

The secondary object of the present invention is to form a seat body by using a mosaic injection method on a plurality of terminals. If four holes are used for comparison, four pairs of eight sets of three opposite discrete terminals need to be placed a total of twenty-four times. The placement of the drawstring is only required to place the plurality of terminals in the mold twice, which can effectively save the labor and cost, and greatly increase the identification of the plurality of terminals when placed, and placed in the mold. The integral structure of the multiple terminals of the inner belt is relatively complete, so that the mold design does not need too many components supporting the plurality of terminals, so as to effectively reduce the difficulty in designing and manufacturing the mold, and at the same time ensure the quality and yield of the manufacturing. In mass production.
