[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-2 As shown, a signal converter comprises a body 1, a mounting surface of the body 1 is provided with a slide groove 2 and a side wing groove 3 connected with the slide groove 2;

[0024] The side wing groove 3 further comprises a clamping member 4 which is slidably arranged in the side wing groove 3, a U-shaped member 31 is arranged in the center of the side wing groove 3, a square groove 41 is opened in the clamping member 4, and a U-shaped member 31 is arranged in the center of the side wing groove 3, and a square groove 41 is opened in the clamping member 4, and a U-shaped member 31 is arranged in the center of the side Figure 2 It can be seen that the side wing groove 3 and the slide groove 2 are T-shaped structures.

[0025] Furthermore, the U-shaped member 31 in the embodiment is located in the square groove 41, and the two opposite side walls of the square groove 41 are provided with elastic clamping arms 42 arranged toward the U-shaped member 31. When the end of the elastic clamping arm 42 is under the end of the U-shaped member 31, one end of the clamping member 4 extends into the slide groove 2 to form a clamping portion 44. At this time, the clamping portion 44 and the one side of the slide groove 2 are provided with a clamping plate 21 protruding toward the clamping member 4, so that the main body 1 can be installed on the mounting plate and slide.

[0026] It should be noted that a stopper 43 protruding toward the notch of the U-shaped member 31 is provided on one side of the square groove 41. When the clamp 4 is pulled, the end of the elastic clamp arm 42 will be embedded in the notches respectively provided at the two top corners of the U-shaped member 31 to form a retention eave 32, thereby maintaining the state in which the clamping portion 44 is separated from the slide groove 2;

[0027] At this time, the limiting block 43 contacts the bottom of the U-shaped member 31 to fill the gap, so that the retention eaves 32 is a C-shaped structure, thereby ensuring that the end of the elastic clamping arm 42 is clamped in the retention eaves 32.

[0028] Then, when the clamping member 4 is pushed to slide into the chute 2 , after the end of the elastic clamping arm 42 is separated from the retention eaves 32 , the elasticity of the elastic clamping arm 42 itself will automatically drive the clamping member 4 to slide, so that the fixing portion 44 extends into the chute 2 .

[0029] In the above technology, the clamping member 4 is pulled to slide in the side wing groove 3, so that the clamping portion 44 is disengaged from the slide groove 2. At this time, the cooperation between the main body 1 and the mounting plate can be released, and the disassembly can be completed without removing the mounting plate.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
