Terminal strip combinations and assembly method of electrical connector made by terminals

Abstract

The invention provides terminal strip combinations and an assembly method of an electrical connector made by terminals. The electrical connector mainly comprises an insulation body and at least two rows of terminal strip combinations, wherein the terminal strip combinations comprise terminals and strips which are connected; the insulation body is provided with two rows of accommodation grooves which are arranged back and forth corresponding to the two rows of terminal strip combinations; each terminal is provided with a base which is bent upwards and forwards to extend for at least one elastic arm; each strip is provided with a plurality of guide strips in an extension way, and each guide strip is connected with the base of the corresponding terminal and bent to form at least one space; and at least a part of elastic arms of the rear row of the terminals are accommodated into a space of the adjacent guide strips of the front row. The structure of the invention can ensure that the elastic arm of each terminal is long enough and has better elasticity, and the base of each terminal is directly connected with each strip without bending, therefore, the contact accuracy of the base with an electronic component is improved, and the terminals can be arranged on the insulation body simply and conveniently and are effectively protected.

Description

【Technical field】 [0001] The invention relates to a terminal strip combination and an assembly method of an electrical connector made of the terminal, in particular to a terminal strip combination for electrically connecting a chip module to a circuit board and an electrical connector made of the terminal assembly method. 【Background technique】 [0002] As computer technology develops toward miniaturization, electrical connectors also develop toward smaller and smaller sizes, which generally include insulating bodies and terminals. In order to meet the miniaturization of electrical connectors, it is common practice to arrange the receiving slots of the insulating body as densely as possible. In this structure, in order to avoid short circuits between the two adjacent terminals, the elastic arms of the terminals are shorter than Ensure there is enough distance, and the short elastic arm will affect the elastic contact performance of the terminal. [0003] In response to the...

Problems solved by technology

[0006] 1. Since the connecting portion 131 is bent to form a vertical body 132 and is perpendicular to the vertical body 132, it is difficult to ensure that the connecting portion 131 and the vertical body 132 are at a fixed angle during the molding process of the terminal 1, and In actual operation, there will inevitably be a few degrees of error, resulting in inaccurate contact positions between terminal 1 and electronic component 2, which will seriously affect the compression contact between the elastic arm of terminal 1 and electronic component 2

[0007] 2. Since the connecting portion 131 is bent to form a vertical body 132 and is perpendicular to the vertical body 132, it is difficult to ensure that the connection portion 131 and the vertical body 132 are at a fixed angle during the molding process of the terminal 1, and In actual operation, there will inevitably be a few degrees of error, resulting in a deviation between the terminal 1 and the terminal receiving groove 41, which makes installation difficult, or damages or damages the terminal, and also affects the installation speed
