Detailed Description

Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, which is formed by punching a metal sheet, and includes a crimping end 10 and a plugging end 20 integrally connected.

The crimp terminal 10 has a crimp groove 101, the crimp terminal 10 includes a base 11, a first crimp arm 12 and a second crimp arm 13 extend from two sides of the base 11, the first crimp arm 12 and the second crimp arm 13 are arranged at a front-to-back interval, the base 11, the first crimp arm 12 and the second crimp arm 13 define a crimp groove 101 that is open to one side, and the crimp terminal 10 is concave-convex and has a plurality of reinforcing ribs 102 formed on an inner wall surface of the crimp groove 101, the reinforcing ribs 102 are arranged at a front-to-back interval, each reinforcing rib 102 is U-shaped and extends from the base 11 to two sides to the corresponding crimp arm.

The inserting end 20 is a frame structure, and has an inserting cavity 201, the inserting cavity 201 is used for inserting external terminals, the side surface of the inserting end 20 is punched inwards to form a contact elastic arm 21, the contact elastic arm 21 is suspended in the inserting cavity 201, the contact elastic arm 21 is used for contacting and conducting with the external terminals, a supporting convex part 22 extends integrally from the contact elastic arm 21, the side surface of the inserting end 20 is punched outwards to form a clamping elastic arm 23 used for clamping and fixing with the external terminals, and the clamping elastic arm 23 is located above the supporting convex part 22; the plug end 20 integrally extends forwards from the front side of the crimping end 10, the opening of the insertion cavity 201 is forwards, the left and right side surfaces of the plug end 20 are both punched inwards to form the contact elastic arms 21, the two contact elastic arms 21 are bilaterally symmetrical and suspended in the insertion cavity 201, the support convex part 22 is positioned at the tail end of one of the contact elastic arms 21, the tail end of the clamping elastic arm 23 extends to one side to form a limit convex part 24, the limit convex part 24 is positioned right above the support convex part 22, when the clamping elastic arm 23 is pressed downwards, the support convex part 22 is contacted with the limit convex part 24, so that the clamping elastic arm 23 stops pressing downwards, and the situation that the clamping elastic arm 23 cannot restore to the original state due to too large pressing amplitude is prevented; in addition, the retaining spring arm 23 is located at the top of the inserting end 20, a slot 202 is formed at the bottom of the inserting end 20, and the slot 202 is opposite to the retaining spring arm 23.
