Connector

Abstract

A connector, belonging to the technical field of circuit board connection, comprises: a first insulator (1) provided with a plurality of through holes (11); A second insulator (2) disposed opposite toand movably connected to the first insulator (1); A plurality of conductive terminals (3), one end of each conductive terminal (3) passing through the through hole (11) and the other end passing through the second insulator (2) and fixedly connected to the second insulator (2); Each conductive terminal (3) is partially arched between the first insulator (1) and the second insulator (2) to form abuffer (31). As that connector is movably connected with the second insulator and the conductive terminal itself is flexible to absorb the vibration and the stress of the cold and heat shock, the stress of the solder joint is reduce, and the reliability of the product is improved; At that same time, the structure and the process of the conductive terminal are simple, so that the cost of the connector is reduced; When used with large currents, the area of the board does not increase.

Description

technical field [0001] The invention relates to the technical field of circuit board connection, in particular to a connector. Background technique [0002] In order to improve space utilization and increase power density. Now the controller is developing in the direction of miniaturization and integration. Due to the improvement of functional requirements, the limitation of the integration of electronic devices and the limitation of the volume of the controller, usually one circuit board cannot arrange all the devices. In most cases, all devices are placed on a circuit board with a layer of circuit boards. In order to realize the signal and circuit connection between the two boards, a connector is needed to connect the two boards. [0003] Especially in the automotive industry, controllers are subject to strong vibration and temperature shocks. This causes the relative positions of the two layers of boards to move away and get closer. Under strong impact, the single-la...

Problems solved by technology

[0009] The purpose of the embodiment of the present invention is to provide a connector, which is flexibly connected to the second insulator through the first insulator, and a buffer part is provided on the conductive terminal, so as to solve the problem in the prior art when a connector connects two layers of circuit boards. Solder joints are prone to cracking under high temperature shock and strong vibration, leading to technical problems of product failure; since the conductive terminal does not have the problem of mating the male end and the female end, it solves the problem of using a male-female end board-to-board connector to connect two terminals in the prior art. When layering circuit boards, the female end needs to meet the requirements of flexibility and tolerance matching in all directions, and a special structural design is required, which makes the structure and process of the female end complicated, and the cost of the mold is high, resulting in the technical problem of high cost of the board-to-board connector. ; By changing the cross-sectional area of ​​the conductive terminal, the requirement of high current can be met, which solves the problem that the connector in the prior art adopts the method of arranging wires. technical problem
