Power terminal and connector assembly

Abstract

The present invention provides a power terminal and a connector assembly, which comprise a base part, a plurality of elastic parts which extend downwards from the base part and are arranged side by side along the left direction and the right direction, a welding part which extends downwards from each elastic part and is provided with a groove which is concavely arranged upwards from the bottom surface of the welding part, the groove is provided with two side walls which are opposite to each other on the left side and the right side and are used for clamping a tin ball, a horizontal central line of the tin ball passes through the two side walls, and an elastic deformation space is formed between every two adjacent elastic parts; and as for the power terminal, the elastic deformation space is arranged between the adjacent elastic parts, the elastic deformation of the elastic parts effectively relieves the pulling force borne by the terminal, the welding part is not pulled and is kept still, the stress of the tin ball can be reduced, and the tin crack is avoided.

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] 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 conducti...

AI Technical Summary

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
