[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As Figures 1-11 shown, the ultra-thin crimping connector provided by the embodiment comprises a plurality of terminals 2 and a base 1. The terminal 2 comprises a holding part 2c, a first contact part 2a and a second contact part 2b. The base 1 is provided with a plurality of holding holes 11 and terminal holes 13. The first contact part 2a and the second contact part 2b are respectively fixed at the upper and lower ends of the holding part 2c. The terminal hole 13 and the holding hole 11 are in communication. The holding parts 2c of the plurality of terminals 2 are clamped in the plurality of holding holes 11 one by one. The first contact part 2a and the second contact part 2b respectively extend outward from the upper and lower ends of the terminal hole 13 away from one end of the holding part 2c. Those skilled in the art can understand that the ultra-thin crimping connector provided by the present embodiment greatly reduces the thickness of the connector by arranging most of the structure of the first contact part 2a and the second contact part 2b in the terminal hole 13, and only retaining the end part exposed outside, thereby meeting the requirement of the development of the product to low height.

[0024] Further, the first contact part 2a comprises a first force arm and a first contact head 23; the holding part 2c comprises a first plate body 26; the first plate body 26 is clamped in the holding hole 11; one end of the first force arm is fixed to the top of the first plate body 26; the first contact head 23 is fixed to the end of the first force arm away from the first plate body 26; the first contact head 23 is an arc-shaped sheet; the first force arm is located in the terminal hole 13; the first contact head 23 protrudes out of the terminal hole 13. Those skilled in the art can understand that the existing terminal 2 force arm is short and prone to yield, causing unstable contact. The present application increases the length of the first contact part 2a through the first force arm, which can effectively avoid the phenomenon of yield and improve the stability of contact. At the same time, the first force arm is located in the terminal hole 13 and does not affect the height of the connector.

[0025] Further, the first force arm comprises a first sheet 21, a second sheet 24 and a third sheet 22; the second sheet 24 is fixed between the first sheet 21 and the third sheet 22; one end of the first sheet 21 away from the second sheet 24 is fixed to the top of the first plate body 26; one end of the third sheet 22 away from the second sheet 24 is fixed to the first contact head 23; the second sheet 24 is arc-shaped; the bending direction of the second sheet 24 is opposite to the bending direction of the first contact head 23; the first contact head 23 bends towards the second contact part 2b.

[0026] Further, the structure of the second contact part 2b is the same as that of the first contact part 2a; the first sheet 21 of the second contact part 2b is fixed to the bottom of the first plate body 26; the second contact part 2b is symmetrically arranged with the first contact part 2a. Those skilled in the art can understand that the present application realizes conduction through the contact of the two groups of second sheets 24 on the first force arm and the second force arm. In this way, both sides of the present application can be stressed simultaneously and uniformly, reducing the risk of unstable contact caused by unilateral terminal 2 overpressure and yield due to inconsistent height of the two sides of the contact, thereby increasing the stability of the contact. The terminal provided by the present application adopts a continuous stamping mode, which is efficient and low in cost.

[0027] Further, the holding part 2c further comprises two groups of second sheets 24; the two groups of second sheets 24 are respectively fixed to the left and right sides of the first sheet 21; the top of the base 1 is further provided with a plurality of square grooves 12; the holding holes 11 are respectively formed at the bottom of the square grooves 12. Those skilled in the art can understand that the square grooves 12 facilitate clamping the holding part 2c in the holding hole 11, and the bottom of the square groove 12 is a riveting surface for the terminal 2, which is lower than the surface of the base 1 and can prevent the holding part 2c from protruding out of the insulator plane, causing the distance to the PCB contact pad to be too close and causing the risk of poor voltage resistance. The terminal and the holding hole are assembled by riveting, which is efficient and low in cost.

[0028] Further, the thickness of the base is 0.4 mm.

[0029] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
