detailed description:

Examples: The following specific examples illustrate the implementation of the present utility model, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The "upper" and "lower" referred to below are consistent with the upper and lower directions of the drawings themselves.

As shown in Figures 1 to 3, a USB connector with fast charging function includes a housing, a plastic body 30 installed with a connecting terminal 31 and arranged in the housing, and a plastic body 30 mounted on the plastic body 30 and The detection terminal 40 for fast charging is located in the housing, wherein the plastic body 30 is formed with a groove for accommodating the detection terminal 40 , the detection terminal 40 and the connection terminal 31 The welding feet of the detection terminal 40 and the welding feet of the connecting terminal 31 are arranged side by side up and down, and the gap area between the welding feet of the detection terminal 40 and the welding feet of the connecting terminal 31 is used to clamp the PCB board. The groove formed on the plastic body 30 is in the shape of an elongated groove. The detection terminal 40 is fixedly arranged in the center of the plastic body 30, and the number is one. One end of the detection terminal 40 extends outside the plastic body 30; the contact portion of the detection terminal 40 is a In the upwardly protruding bending structure, the top of the contact part is press-formed with a groove 41, the setting of the groove 41 improves the reliability and stability of the connection, and the connection quality is good.

As shown in FIG. 1, the housing includes a main housing 10 and a cover part 20 matched with the main housing 10, the main housing 10 and the cover part 20 are jointly formed A cavity for accommodating the plastic body 30 . A pair of side walls of the main housing 10 are formed with a first limiting hole 11, and a pair of second limiting holes 12 are formed on the top end surface; a pair of first side walls 21 are integrally formed on the cover part 20 And a pair of second side walls 22, the outer surface of the first side wall 21 is formed with a block 211 that matches the first limiting hole 11, and the top of the block 211 is formed with a guide for guiding inclined plane. When installing the cover part 20 on the main housing 10, first insert the top of the second side wall 22 into the second limiting hole 12, when the top of the second side wall 22 passes through After passing through the second limiting hole 12, the block 211 is inserted into the first limiting hole 11 through the guidance of the inclined plane, and at this time, the top of the second side wall 22 is bent Fold at a certain angle, so as to realize the connection between the cover part 20 and the main casing 10, and the casing composed of the cover part 20 and the main casing 10 can effectively block external moisture and dust The intrusion of particles plays a role of protecting the detection terminal 40 and the plastic body 30 , prolonging the service life of the detection terminal 40 .
