Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, a large current USB male connector includes a plastic shell 10 and four gold fingers 20.

Four containing grooves 11 are formed in one end of the rubber casing 10 towards the middle, and strip-shaped holes 12 corresponding to the four containing grooves 11 are formed in the side wall of one side of the rubber casing 10. Wherein the width of the strip-shaped holes 12 at the two sides is larger than the width of the two strip-shaped holes 12 at the middle part.

The gold finger 20 comprises a first contact area 21 and a second contact area 22, wherein the side wall of the first contact area 21 is provided with a raised touch bar 211, and the width of the touch bars 211 at two sides is greater than the width of the two touch bars 211 at the middle part. Because the touch bars 211 on the two sides of the USB male connector belong to the power supply PIN, the effective contact area is increased to reduce the internal resistance, so that the internal energy loss in the large-current transmission process is reduced, and the self-heating phenomenon can be effectively relieved.

The four gold fingers 20 are respectively inserted into the four accommodating grooves 11 for fixation, the first contact area 21 is disposed in the accommodating grooves 11, the four touch bars 211 respectively extend out of the four strip-shaped holes 12, and one end of the second contact area 22, which is far away from the first contact area 21, extends out of the accommodating grooves 11.

By adopting the design of the inserting pieces, the front side and the back side of a user can be distinguished by visual observation or by hand touch, so that the user can conveniently and quickly insert and pull out the front side and the back side, and the time for distinguishing the front side and the back side of the user is saved. Heavy current and data signal are switched on to the unilateral, and the short circuit can be effectively avoided in the typical contact of the other side and the USB female socket, so that the stability and the safety of electric connection are improved. Meanwhile, the gold finger 20 on one side is reduced, and the production cost of the product can be correspondingly reduced.

Two heavy grooves 14 have been seted up to this embodiment rubber shell 10 opposite side lateral wall, make the female elastic clamping piece card of seat of USB fixed in heavy groove 14, promote the stability of connecting.

Glue shell 10 one end and be equipped with a plurality of partition walls 13, the separation is arranged at second contact area 22 and partition wall 13 interval, avoids the soldering tin flow in later stage data line assembling process to adjacent second contact area 22, and the outer wall that this embodiment second contact area 22 extends to glue shell 10 is equipped with the pit (the recess of matrix arrangement) for the increase with the area of contact of soldering tin.
