Problems solved by technology

However, when the electrical connector is welded on the circuit board 600 and the insulating body 8 is deformed, the conductive terminal 7 will be pulled due to the deformation of the insulating body 8. Since there is not enough space for the conductive terminal 7 to undergo sufficient elastic deformation, it is not enough Buffer the pulling force on the soldering part, so that the soldering part is pulled and moved, which is easy to cause tin cracking, thus affecting the normal electrical connection of the electrical connector

Abstract

The present invention provides a power terminal and connector assembly, comprising: a base portion, a plurality of elastic portions extending downward from the base portion side by side along the left and right directions, and extending downward from each elastic portion to form a welding portion, the welding The bottom part is provided with a groove upwards from its bottom surface, and the groove has left and right opposite side walls to clamp a solder ball together, a horizontal center line of the solder ball passes through the two side walls, and two adjacent An elastic deformation space is formed between the elastic parts; for the power supply terminal, there is an elastic deformation space between adjacent elastic parts in the present invention, and the elastic deformation of the elastic part can effectively relieve the pulling force on the terminal, so that the welding part is not pulled Keeping the soldering part still can reduce the force on the solder ball and avoid tin cracking.

Description

【Technical field】 [0001] The invention relates to a terminal and a connector assembly, in particular to a power terminal and a connector assembly capable of preventing tin cracking. 【Background technique】 [0002] Such as figure 1 , figure 2 The disclosed conductive terminal 7 has a main body portion 71 in the form of a flat plate. Fixing portions 711 are provided on the left and right sides of the main body portion 71 to fix the conductive terminal 7 to the insulating body 8, and extend upwards from the main body portion 71. A plurality of elastic arms 72 are arranged in a row along the left and right directions, and the top of the elastic arms 72 abuts against a chip module 500 upwards, and a plurality of grooves 73 are recessed upwards on the bottom surface of the main body 71 and arranged side by side along the left and right directions. The groove 73 has left and right opposite side walls 731 to clamp the solder 9 together, so as to solder the conductive terminal 7 t...
