Background

The connector generally used for power transmission in the 5G communication field is an SMT high current-carrying power connector, and the SMT high current-carrying power connector is generally composed of a male socket and a female socket, wherein the male socket and the female socket respectively comprise a colloid and a terminal, and the colloid is interference between the terminal and the colloid, i.e. interference fit, so as to generate a friction force and maintain on a pcb.

At present, under a small spacing, for example, the spacing between adjacent terminals is 2.00mm, rated current which can pass through each PIN terminal is too small, and the spacing of the connectors which can pass through large current is too large, and basically, the spacing is above 5.00mm, so that the space occupied by a PCB (printed circuit board) is too large.

The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

Referring to fig. 1 to 6, an embodiment of the present utility model discloses a power connector, which includes a female socket 1 and a male socket 2 that can be plugged onto the female socket 1, wherein the female socket 1 includes a female colloid 11 and a plurality of female terminals 12, the female terminals 12 are plugged into the female colloid 11 with a gap left between two adjacent female terminals 12; the male base 2 comprises a male colloid 21 which can be matched with the female colloid 11, and a plurality of male terminals 22 which are inserted into the male colloid 21 and correspond to the female terminals 12; each female terminal 12 is of an integrally formed structure and has at least two resilient contact portions 121 formed by stamping at the upper portion thereof, and each male terminal 22 is insertable between the at least two resilient contact portions 121 of the corresponding female terminal 12.

The female terminal 12 is made of a high-conductivity copper material and is manufactured by a stamping die. The elastic contact area between the head of the female terminal 12 and the male terminal 22 is processed by piercing and tearing first and bending the elastic structure later, instead of conventional processing by blanking first, i.e. cutting off the material and bending the elastic structure later.

The bottleneck in the transmission of large current is the point where the female terminal 12 contacts the male terminal 22 with the greatest resistance. The puncturing and tearing process can avoid material loss at the contact position, and maximize the through-flow cross-sectional area of the material, so that the generated resistance is lower, and larger current can be transmitted in a limited space.
