Detailed Description

The detailed description and technical contents of the present invention will be described below with reference to the drawings, however, the drawings are only for illustrative purposes and are not intended to limit the present invention.

Referring to fig. 1 to 5, the present invention provides a high current connector, the high current connector 10 mainly includes a sleeve 1, a crown spring 2 and an annular cover 3.

As shown in fig. 1 to 5, the sleeve 1 is made of conductive material, the sleeve 1 has a port 11, an inner wall 12 and an outer wall 13, one or more annular barbs 14 extend from the outer wall 13, the sleeve 1 has an annular groove 15 at the junction of the outer wall 13 and the port 11, and the annular barbs 14 are formed by extending from a bottom wall 151 of the annular groove 15.

In addition, a connecting tube 16 extends from one end of the sleeve 1 away from the port 11, and a notch 161 is formed inward at an opening of the connecting tube 16, so that a wire (not shown) can be conveniently inserted into and positioned in the connecting tube 16 through the notch 161, and then the wire (not shown) and the connecting tube 16 are welded through the notch 161, so as to achieve the purpose of stably holding the wire (not shown) by the connecting tube 16 and the solder.

As shown in fig. 1 to 2 and 4 to 5, the crown spring 2 is made of a conductive material, the crown spring 2 is disposed inside the sleeve 1 and abuts against the inner wall 12, and further, as described below, the crown spring 2 has a two-ring loop 21 abutting against the inner wall 12 and a plurality of spring leaves 22 integrally extending from the two-ring loop 21 and bridging between the two-ring loop 21, each spring leaf 22 has a V-shaped turning portion 221 bending and protruding in a direction away from the inner wall 12, and the stop block 31 is used for stopping one of the two-ring loop 21.

In addition, the crown spring member 2 is formed by winding a metal plate 20 in a C shape, so that each ring 21 is wound as a C-shaped ring, but the crown spring member 2 may also be a metal ring body, which is not limited in this embodiment.

As shown in fig. 1 to 2 and 4 to 5, the annular cover 3 is made of a conductive material, and the annular cover 3 is sleeved on the port 11 to form a socket product of the high-current connector 10.
