In summary, the main technical means of the utility model is to provide a connector socket, including a metal shell with a slot inside, and a fixing seat assembled in the slot, the fixing seat has two side blocks, And a tongue located between the two side blocks, a USB terminal group and an eSATA terminal group are respectively provided on the upper and lower surfaces of the tongue, wherein,

The two side blocks located between the USB terminal group and the metal shell are opposite to the side, respectively provided with a concave side slot, and the two side slots extend and communicate with the rear end surface of the side block;

There are two clips, which are respectively inserted into the side slots, and have a positioning piece inserted into the rear section of the side slot, and an elastic arm extending forward from the front end of the positioning piece. The free ends of the two elastic arms are provided with Oppositely protruding pressing protrusions, and the pressing protrusions protrude from the side slots and are located in the slots of the metal shell, and protruding hooks are provided on both sides of the positioning piece, and the positioning piece is at least on the upper surface or the lower surface A protruding clamping part is provided, and the hook part and the clamping part are correspondingly inserted into the peripheral wall of the rear section of the side slot.

After implementing above-mentioned technical means, the concrete benefit that the utility model can obtain is:

Since the utility model is respectively provided with a clip on the two side blocks of the fixing seat, and the two clips are respectively protruded with a pressing protrusion located in the slot of the metal shell, when the USB plug is inserted, its side will be pushed up The pressing protrusion forms a clamping force on the side by the elastic force of the elastic arm, that is, the USB plug is simultaneously clamped by the elastic arm of the metal shell and the clamping pieces on both sides to improve the stability when inserted and combined sex.

【Detailed ways】

In the following description, "front end" refers to the end where the metal shell of the connector is inserted into the connector, "rear end" is the opposite end, "bottom end" refers to the end where the metal shell of the connector is inserted into the circuit board, and "top end" opposite to the bottom.

Please refer to Fig. 1 to Fig. 3, the connector socket provided by the utility model is a plug for two different protocols, such as a universal serial bus (USB) and a serial advanced attachment technology (eSATA) two specifications, which It still includes a hollow metal shell 10 with a slot 100 inside, and an insulating fixing base 20 assembled in the slot 100. The top and bottom plates of the metal shell 10 are punched into two free pieces respectively. Elastic arms 11, 12 extending forward.

And this fixed seat 20 is to have a connecting piece 21 that is positioned at the rear end, two pieces are respectively arranged on connecting piece 21 two sides and extend forward side block 22, and one is positioned between two side pieces 22 and is integrally by connecting piece 21 towards. The front extended tongue 23 has a distance between the two sides of the tongue 23 and the side block 22, and a USB terminal group 30 and an eSATA terminal group 40 are respectively assembled on the upper and lower surfaces of the tongue 23, which respectively have several pieces of conductive USB terminal, eSATA terminal.

The two side blocks 22 peripheral walls of the fixing base 20 are provided with contours for corresponding USB plugs and eSATA plugs, so as to achieve the purpose of foolproofing.

The basic structure of the aforementioned utility model is almost the same as that of the reference case. In order to enhance the clamping force of the connector socket on the plug, the utility model is further provided with a concave side slot 221 at the rear end of the two side blocks 22 respectively. The slot 221 is located on the side block 22 between the USB terminal set 30 and the metal shell 10, and communicates with the slot 100 between the USB terminal set 30 and the metal shell 10, so that a clip 50 can be inserted into it. The card is fixed.

Please refer to Fig. 2, 4, and 5, the clip 50 is a metal plate body, which has a positioning piece 51 located at the rear section of the fixing seat 20, and an elastic spring extending forward is provided in the middle section of the front end of the positioning piece 51. Arm 52, the free ends of the two elastic arms 52 are provided with oppositely protruding pressing protrusions 520, and a protruding triangular hook portion 53 is respectively provided on both sides of the positioning piece 51, and the hook portion 53 is located in the direction of insertion (that is, towards the front end) This surface) is set to be inclined, and towards the rear end, this surface is set to be perpendicular to the side of the positioning piece 51, and the positioning piece 51 is provided with a protruding clamping portion 54 at least on the upper surface or the lower surface, so as to be correspondingly clamped on the side insert Groove 221, and preferably on the upper surface and the lower surface of the positioning piece 51, the protruding clamping portion 54 is punched and formed respectively, and the clamping portion 54 extends in the same direction as the side slot 221 and is set as elongated , into the side slot 221 for easy guidance. And the width of the rear section of the side slot 221 is set wider to form a retaining edge 222 adjacent to the rear end peripheral wall of the side slot 221, and the clip 50 is inserted into the side slot 221, and the front end of the positioning piece 51 promptly stops on the blocking edge 222 , and is positioned by forcing the hook portion 53 and the locking portion 54 of the positioning piece 51 into the peripheral wall of the side slot 221 . And as can be seen from the drawings, under normal conditions, the pressing protrusion 520 of the clip 50 is the protruding side slot 221, and is located in the slot 100 between the USB terminal group 30 and the metal housing 10 for the USB plug 60 mating inserts.

When the USB plug 60 is inserted as shown in FIG. 6, its side pushes against the pressing protrusion 520 of the clip 50, so that the pressing protrusion 520 and the elastic arm 52 are biased in the side slot 221 of the fixing seat 20, and By virtue of the elastic force of the elastic arm 52 , the pressing protrusion 520 is clamped on the side of the USB plug 60 . Therefore, when the USB plug 60 is plugged in, it is simultaneously subjected to the clamping force of the elastic arm 11 shown in FIG. 1 and the clips 50 on both sides, thereby improving the coupling degree during plugging.
