Abstract

An electrical connector includes an insulation body having a base portion and a tongue located at a front end of the base portion. Multiple terminals are fixed on the base portion and partially exposed from a surface of the tongue. An outer metal casing surrounds the base portion and the tongue and forms an insertion space receiving the tongue. The outer metal casing has a bottom wall and two side walls. Each side wall extends downward to form a stop wall. Each stop wall extends downward to form two soldering pins. The four soldering pins are arranged in two rows. A cushion block is located below the bottom wall and fixed on the two stop walls. Four protruding blocks are formed by protruding downward from a bottom surface of the cushion block. At least two of the protruding blocks are located disposed between the soldering pins in the two rows.

Claims

1. An electrical connector, comprising:

an insulation body, having a base portion and a tongue located at a front end of the base portion;

a plurality of terminals, fixedly disposed on the base portion and partially exposed from the surface of the tongue;

an outer metal casing, surrounding the base portion and the tongue and forming an insertion space receiving the tongue, wherein the outer metal casing has a bottom wall located below the insertion space and two side walls located at two opposite sides of the bottom wall, the two side walls respectively extend downward to form two stop walls located below the bottom wall, and the two stop walls extends downward to form four soldering pins, wherein two of the four soldering pins are formed on each of the two stop walls, and the four soldering pins are arranged in two rows in a front-rear direction; and

a cushion block, located below the bottom wall and fixedly disposed on the two stop walls, wherein four protruding blocks are formed by protruding downward from a bottom surface of the cushion block, and at least two of the four protruding blocks are located between the soldering pins in the two rows.

2. The electrical connector according to claim 1, wherein the four protruding blocks are arranged in two rows in the front-rear direction, and comprise two first protruding blocks located in a front row and two second protruding blocks located in a back row, and wherein the second protruding blocks are located between the soldering pins in the two rows.

3. The electrical connector according to claim 2, wherein distances from the second protruding blocks to the soldering pins in one of the two rows and distances from the second protruding blocks to the soldering pins in the other of the two rows are not equal.

4. The electrical connector according to claim 2, wherein areas of bottom surfaces of the two protruding blocks in a same row are equal, and the first protruding blocks are not connected with a side edge of the bottom surface of the cushion block.

5. The electrical connector according to claim 2, wherein the two stop walls are respectively provided with two fastening portions for fastening the cushion block, and the two fastening portions are located in front of the soldering pins in a front row.

6. The electrical connector according to claim 5, wherein the two fastening portions and the first protruding blocks are arranged in a same row in the front-rear direction.

7. The electrical connector according to claim 1, wherein two opposite sides of the cushion block respectively protrude to form two buckling blocks, each of the two stop walls is provided with a buckling hole corresponding to and fastened to one of the two buckling blocks, and on a same stop wall, the fastening hole is located between upward extending lines of the two soldering pins.

8. The electrical connector according to claim 1, wherein a front end surface of the cushion block is in front of a front end surface of the tongue.

9. The electrical connector according to claim 1, wherein the base portion comprises a connecting portion formed by extending backward from the tongue and a elevated portion formed by extending backward from the connecting portion, a bottom surface of the elevated portion is lower than a bottom surface of the connecting portion, and the cushion block is located right below the connecting portion and the tongue and in front of the elevated portion.

10.
