[0027] The utility model will be explained in detail below. Figures 1-6 The utility model is explained in detail.

[0028] A relay, comprising a socket 10 and a module 20, one of the socket 10 and the module 20 is equipped with a guide block 50, the other is equipped with a guide groove 30 matched with the guide block 50, specifically, the socket 10 is equipped with the guide groove 30, and the module 20 is equipped with the guide block 50. The side wall of the guide groove 30 is equipped with a spring buckle 40, the guide groove 30 is equipped with an accommodating space 60 for accommodating the elastic deformation of the spring buckle 40, and the space below the sliding groove constitutes a fixed space 70 of the guide block 50;

[0029] During the installation of the module 20 on the socket 10, the guide block 50 abuts against the spring buckle 40 and makes it deform outward, when the guide block 50 passes through the spring buckle 40 and enters the fixed space 70, the spring buckle 40 resets inward to the initial position, and when the guide block 50 is separated from the fixed space 70, the guide block 50 abuts against the end of the spring buckle 40.

[0030] Therefore, even if the clamping force of the spring buckle 40 is small, the guide block 50 can be reliably connected through the limiting action of the spring buckle 40, and the problem that the module 20 is difficult to install during use or easily separated in a vibrating environment is reduced.

[0031] In the embodiment, the opposite side walls of the guide groove 30 are respectively provided with elastic buckles 40, and the gap between the two elastic buckles 40 constitutes an installation channel for the sliding block 50 to slide into the fixed space 70. When the elastic buckle 40 is in the initial position, the width H1 of the installation channel is smaller than the width H2 of the sliding block 50, as shown in the figure. Figure 4 The two elastic buckles 40 form a more stable anti-disengagement limiting structure, further avoiding the problem that the module 20 is difficult to be installed or easily disengaged in a vibrating environment during use.

[0032] In the embodiment, the two elastic buckles 40 are provided with opposite convex portions, and the end of the convex portion away from the fixed space 70 is provided with a first guide surface 401. During the installation of the module 20, the end of the sliding block 50 facing the first guide surface 401 is provided with a second guide surface 501. Further, the first guide surface 401 is a bevel surface, and the second guide surface 501 is an arc surface. During installation, the second guide surface 501 abuts against the second guide surface 501, thereby deforming the elastic buckle 40 outward, facilitating the sliding block 50 to pass through the installation channel and enter the fixed space 70.

[0033] In the embodiment, the end of the elastic buckle 40 close to the fixed space 70 is provided with a first anti-disengagement surface 402. During the disassembly of the module 20, the end of the sliding block 50 facing the first anti-disengagement surface 402 is provided with a second anti-disengagement surface 502. Further, the first anti-disengagement surface 402 is an arc surface, and the second anti-disengagement surface 502 is a flat surface. During disassembly, the second anti-disengagement surface 502 abuts against the first anti-disengagement surface 402. Since the second anti-disengagement surface 502 is a flat surface, a large external force is required during disassembly, so that under non-human conditions, the module 20 is difficult to be disassembled from the socket 10, thereby creating conditions for disassembling the module 20 in case of failure, maintenance, etc.

[0034] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit and essence of the utility model shall be covered within the protection scope of the utility model.
