It should be noted that the electrical connector in the new type of use may be a USB interface, specifically, the USB interface may be a USB2.0 or USB3.0 interface, and generally, the electrical connector is an interface installed on an electronic device (such as a computer, a walkman, a cat-wiry, a television, etc.), and a plug (such as a USB connector) for a power supply connector is inserted to achieve an electrical connection function.

In a specific embodiment, the housing 2 is provided with a first window 28, and the elastic sheet 24 extends from an inner wall of the first window 28 into the housing 2. So set up, when shell 2 and inner shell 1 assembly, shell fragment 24 can be from pegging graft in locating hole 11 to play the effect of location and preliminary connection shell 2 and inner shell 1.

Specifically, the inner shell 1 is provided with an inner cavity 13, the inner cavity 13 is communicated with the outside of the inner shell 1 through the positioning hole 11, and when the outer shell 2 and the inner shell 1 are assembled, the elastic sheet 24 is positioned outside the inner cavity 13. It will be appreciated that after the outer housing 2 is assembled with the inner housing 1, the spring 24 is not inserted into the inner cavity 13, and when the plug of the other electrical connector is inserted into the inner cavity 13, the spring 24 is prevented from wearing the plug of the other electrical connector.

In a specific embodiment, the housing 2 includes a main body 21, and a first side 22 and a second side 23 bent and extended from two sides of the main body 21, where the first side 22 and the second side 23 are respectively provided with a spring piece 24 and a fixing piece 25. The first side 22 is provided with the elastic sheet 24 and the fixing piece 25, the second side 23 is also provided with the elastic sheet 24 and the fixing piece 25, and two opposite sides of the inner shell 1 are respectively provided with the positioning hole 11 and the fixing hole 12, so that the outer shell 2 can be positioned and fixedly connected with the inner shell 1 at two sides of the inner shell 1, so that the inner shell 1 and the outer shell 2 are installed more firmly.

Specifically, the fixing piece 25 is inserted into the fixing hole 12 after being bent, and abuts against the inner wall of the fixing hole 12 facing to one side of the body portion 21, wherein the fixing piece 25 is matched with the body portion 21 to clamp the inner shell 1 after being bent, so as to fixedly connect the outer shell 2 and the inner shell 1. It can be understood that the fixing piece 25 is inserted into the fixing hole 12 after being bent, and abuts against the inner wall of the fixing hole 12 facing the side of the body portion 21, so that the fixing piece 25 is matched with the body portion 21, the effect of clamping the inner shell 1 is achieved, and the firmness of assembling the inner shell 1 and the outer shell 2 is improved.

The housing 2 may be provided with a second window 29, and the fixing member 25 may extend from an inner wall of the second window 29. Further, a second window 29 is formed on each of the first side portion 22 and the second side portion 23.

Specifically, the body portion 21 is provided with a clamping groove 26, and the inner shell 1 is provided with a protrusion 14, wherein when the outer shell 2 and the inner shell 1 are assembled, the protrusion 14 is inserted into the clamping groove 26. The engagement of the engagement groove 26 with the protrusion 14 may further define the relative positions of the inner and

outer shells

1 and 2 and enhance the connection strength of the inner and

outer shells

1 and 2.

In one embodiment, the inner shell 1 is provided with an elastic member 15 extending towards the inside thereof for fixing a connection plug inserted into the inner cavity 13. The connection plug may be considered as a plug of another electrical connector, and when the connection plug is inserted into the cavity 13, the elastic member 15 may abut against the connection plug, thereby improving the connection firmness of the electrical connector (corresponding to an interface) of the present utility model and the other electrical connector (corresponding to a joint). As shown in fig. 1, elastic members 15 may be provided on each side wall of the inner case 1.

Specifically, the outer shell 2 is provided with an avoidance groove 27, and when the outer shell 2 is assembled with the inner shell 1 and the connecting plug is inserted into the inner cavity 13, the elastic member 15 is partially positioned in the avoidance groove 27 under the action of the connecting plug. The escape groove 27 serves to escape the elastic member 15, thereby preventing the elastic member 15 from being damaged by the pressing of the elastic member 15 by the housing 2 and the connection plug. The avoidance grooves 27 may correspond to the elastic members 15 one by one, that is, each avoidance groove 27 corresponds to one elastic member 15, but the number of elastic members 15 may be greater than the number of avoidance grooves 27, for example, as shown in fig. 1 and fig. 2, the body portion 21, the first side portion 22, and the second side portion 23 on the outer housing 2 may be provided with the avoidance grooves 27, in which the bottom of the inner housing 1 is not wrapped by the outer housing 2, so that the bottom of the inner housing 1 may be provided with the elastic members 15, and the number of elastic members 15 may be greater than the number of avoidance grooves 27.

In one embodiment, the elastic sheet 24 and the housing 2 are integrally formed; and/or the fixing member 25 is of unitary construction with the housing 2. The integral structure can omit the process of installing the elastic sheet 24 and the fixing piece 25 on the shell 2, thereby improving the production efficiency of the shell and reducing the production cost of the shell.

In summary, in the assembly process of the inner shell 1 and the outer shell 2, the shell of the utility model is inserted into the positioning hole 11 through the elastic sheet 24, so as to play roles of preliminary positioning and connection of the inner shell 1 and the outer shell 2; then the fixing piece 25 is bent under the action of external force and then inserted into the fixing hole 12, so as to firmly connect the outer shell 2 and the inner shell 1 together. The inner shell 1 and the outer shell 2 in the shell have the advantages of being accurate in assembly and firm in connection.
