DETAILED DESCRIPTION

[0027] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figures 1-7 The present application provides a technical solution: comprising: a shell mechanism 1, comprising an insulating shell 100, the insulating shell 100 has a plug-in place 4 at the front end in the plug-in direction, the insulating shell 100 has a mounting portion at the rear end in the plug-in direction, the mounting portion has an internal space, the two opposite inner sides of the mounting portion are provided with a limiting assembly 101, and the limiting frame 106 is located in front of the limiting assembly 101. In an embodiment, the insulating shell 100 is internally provided with a stabilizing groove 102, and the stabilizing groove 102 extends along the plug-in direction. The limiting assembly 101 and the limiting frame 106 are located in the stabilizing groove 102, and the limiting assembly 101 and the limiting frame 106 extend along the plug-in direction of the connector.

[0029] As Figure 2 With Figure 3 , the inside of the shell mechanism 1 is provided with a connecting assembly 2, the connecting assembly 2 is installed in the mounting portion, and the front end is exposed to the plug-in place 4. The connecting assembly 2 comprises an electrical connection block 201, a first stainless steel terminal 202, a second stainless steel terminal 204 and a plug-in assembly 206. The front end of the plug-in assembly 206 is exposed to the plug-in place 4. One end of the second stainless steel terminal 204 is fixedly connected to the rear end of the plug-in assembly 206, and the other end extends towards the electrical connection place 5 of the connector. The front end of the electrical connection block 201 is fixedly connected with the rear end of the plug-in assembly 206. The plug-in assembly 206 comprises at least one power terminal, the power terminal has a plug-in portion at the front end and a fixed portion at the rear end. The fixed portion is flat and fixedly connected with the electrical connection block 201. The plug-in portion comprises a plurality of elastic arms, which are exposed to the plug-in place 4. The first stainless steel terminal 202 is fixedly connected with the electrical connection block 201, and the two sides extend towards the plug-in place 4 of the connector. That is, the extension direction of the first stainless steel terminal 202 is opposite to that of the second stainless steel terminal 204.

[0030] As Figure 2 , Figure 3 , Figure 5 With Figure 7The outer wall surface of the electrical connection block 201 is movably connected with the inner wall surface of the stabilizing groove 102, that is, the outer wall of the electrical connection block 201 can abut against the inner wall of the stabilizing groove 102. The end portions of the two sides of the electrical connection block 201 close to the plug-in portion 4 are abutted against by the limiting frame 106, so that the electrical connection block 201 is limited by the limiting frame 106 in the plug-in direction, thereby achieving the effect of positioning the electrical connection block 201 in the direction perpendicular to the plug-in direction.

[0031] The two sides of the first stainless steel terminal 202 are clamped by the limiting plate 105 and the limiting frame 106. That is, the outer wall of the first stainless steel terminal 202 is limited by the gap between the limiting plate 105 and the limiting frame 106.

[0032] The two sides of the first stainless steel terminal 202 can be provided with a stainless steel fixing sheet 203. Specifically, the two sides of the first stainless steel terminal 202 extend outwardly to form the stainless steel fixing sheet 203. As shown in Figure 3 The first stainless steel terminal 202 can be approximately in the shape of a U. The two sides extend outwardly to form the stainless steel fixing sheet 203, and the first stainless steel terminal 202 and the stainless steel fixing sheet 203 are not located in the same plane, as shown in Figure 3 The connection between the first stainless steel terminal 202 and the stainless steel fixing sheet 203 can be approximately in a curved state.

[0033] In one embodiment, the limiting assembly 101 includes a first limiting block 103 and a second limiting block 104, and is located on the inner wall surface of the stabilizing groove 102 and extends in the plug-in direction of the connector.

[0034] The stainless steel fixing sheet 203 of the first stainless steel terminal 202 is clamped between the first limiting block 103 and the second limiting block 104. Therefore, the outer wall of the stainless steel fixing sheet 203 is limited by the gap between the first limiting block 103 and the second limiting block 104. That is, the first stainless steel terminal 202 is limited in the direction approximately perpendicular to the connecting surface of the plug-in assembly 206. Here, the size of the gap between the first limiting block 103 and the second limiting block 104 can be approximately matched with the thickness of the stainless steel fixing sheet 203.

[0035] On the other hand, when the connecting assembly 2 is installed into the insulating shell 100, the stainless steel fixing sheet 203 of the first stainless steel terminal 202 can enter the insulating shell 100 along the guide groove formed between the first limiting block 103 and the second limiting block 104, and then the two sides of the first stainless steel terminal 202 enter the gap between the limiting plate 105 and the limiting frame 106 to be positioned at the predetermined position, thereby facilitating the positioning of the electrical connection block 201 after being placed.

[0036] In addition, since the stainless steel fixing plate 203 is not located in the same plane as the stainless steel terminal 202, the stainless steel fixing plate 203 is not easily separated from the first limiting block 103 and the second limiting block 104 due to displacement (or shaking) of the first stainless steel terminal 202 under stress, thereby increasing the stability of the overall structure.

[0037] In one embodiment, the top of the first limiting block 103 and the top of the second limiting block 104 are provided with inclined surfaces, and the top of the limiting plate 105 and the top of the limiting frame 106 are provided with inclined surfaces to match the bending of the connection between the first stainless steel terminal 202 and the stainless steel fixing plate 203, thereby facilitating insertion of the first stainless steel terminal 202 and the stainless steel fixing plate 203.

[0038] The second stainless steel terminal 204 can be provided with an inclined stainless steel plate 205, and the second stainless steel terminal 204 extends to form the inclined stainless steel plate 205 in a direction away from the plug-in assembly 206. That is, the inclined stainless steel plate 205 is slightly curved and does not fit the surface of the plug-in assembly 206. The second stainless steel terminal 204 is limited by the limiting frame 106.

[0039] In one embodiment, the space between the limiting plate 105 and the limiting frame 106 is matched with the thickness of the first stainless steel terminal 202, so that the first stainless steel terminal 202 can be fixed between the limiting plate 105 and the limiting frame 106.

[0040] In one embodiment, the limiting frame 106 is connected to the inner wall surface of the stabilizing groove 102, and the limiting plate 105 extends from the front end of the second limiting block 104 and is adjacent to and spaced from the limiting frame 106 to form a gap.

[0041] In one embodiment, the limiting frame 106 can be provided with a protrusion 107 located on the side of the top of the limiting frame 106 away from the limiting plate 105. In other words, the protrusion 107 extends from the top of the limiting frame 106 (the end not connected to the insulating shell 100) away from the side of the limiting plate 105, that is, the limiting frame 106 is generally L-shaped and defines a limiting space in the middle.

[0042] As Figure 4 With Figure 7 When the connection assembly 2 is installed in the shell mechanism 1, the inclined stainless steel plate 205 is first deformed by being pressed by the protrusion 107, and then the second stainless steel terminal 204 enters the limiting space and the stainless steel plate 205 resets, and the protrusion 107 abuts against the inclined stainless steel plate 205. Therefore, the protrusion 107 limits the stainless steel plate 205 in the plug-in direction, thereby achieving the effect of limiting the connection assembly 2 in the plug-in direction.

[0043] The stainless steel structure of the first stainless steel terminal 202, the stainless steel fixing sheet 203, the second stainless steel terminal 204 and the inclined stainless steel sheet 205 increases the mechanical stability and the mechanical strength, and can resist external vibration and impact force.

[0044] In summary, when assembled, the electrical connection block 201 is inserted into the mounting portion at the rear end of the insulating shell 100, the electrical connection block 201 moves along the stable groove 102, the stainless steel fixing sheet 203 is limited through the gap between the first limiting block 103 and the second limiting block 104, and then the two sides of the first stainless steel terminal 202 extending forward enter the gap between the limiting plate 105 and the limiting frame 106 for limiting, so that the first stainless steel terminal 202 and the stainless steel fixing sheet 203 can be stably arranged in the shell mechanism 1. At the same time, one side of the second stainless steel terminal 204 moves forward along one side of the limiting frame 106 (towards the plug-in part 4) to one side of the protrusion 107, the protrusion 107 contacts the inclined surface of the inclined stainless steel sheet 205, and then the inclined stainless steel sheet 205 is extruded, and then the inclined stainless steel sheet 205 is not extruded by the protrusion 107 after the second stainless steel terminal 204 is stable, and then the inclined stainless steel sheet 205 is reset, so that the inclined stainless steel sheet 205 is blocked by the protrusion 107. During the plug-in and plug-out operation, the outer wall of the insulating shell 101 is plugged and unplugged by hand, the structure of the first limiting block 103, the second limiting block 104, the limiting plate 105, the limiting frame 106 and the protrusion 107, the first stainless steel terminal 202, the stainless steel fixing sheet 203, the second stainless steel terminal 204 and the inclined stainless steel sheet 205 increases the mechanical stability and the mechanical strength, so that the plug-in and plug-out force cannot affect the electrical connection block 201.

[0045] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments without departing from the technical scheme of the present application, according to the technical essence of the present application, still belongs to the protection scope of the present application.
