[0009] Furthermore, the four inner corners of the installation slot are fixedly connected with guide pillars, and the four corners of the lower surface of the relay body are provided with guide holes corresponding to the guide pillars.

[0010] Furthermore, the plug hole extends to the bottom of the mounting groove, and the thickness of the plug board is the same as the width of the plug hole.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the above scheme, when disassembling, pressing the button drives the rectangular rod and the rack to slide downward and compress the spring.

Then the rack continues to move downward and squeezes the movable rod. At this time, the movable rod rotates around the pin shaft and pushes the conductive contact part out of the slot through the roller, so that the relay body can be disassembled from the relay mounting part with one hand, which is very convenient to use;

In the above scheme, during installation, the relay body is aligned with the installation slot on the base, and then the plug-in board on the relay body is inserted into the inside of the plug-in hole, and then the relay body is pressed. At this time, the plug-in board pushes the two eccentric clamps to move in the opposite direction around the rotating shaft and form a second distance. Since the second distance is greater than the thickness of the plug-in board, the relay body can be smoothly installed in the inside of the installation slot and squeeze the sealing ring. The sealing effect of the plug-in joint is ensured by the sealing ring, thereby preventing dust or moisture from entering and causing a short circuit at the plug-in joint, thereby improving the safety of the relay during use;

[0021] 3. In the above scheme, by setting an elastic clamping component, the restoring force of the spring can make the two eccentric clamps approach each other when in use. The first distance formed after approaching each other is smaller than the thickness of the plug-in board, so that the plug-in board can be firmly fixed even in a vibration environment, thereby ensuring that the relay body is installed more firmly on the base, making the conductive contact part evenly stressed in the slot, effectively preventing the conductive contact part from falling out of the slot, and realizing stable signal transmission.

[0033] A cavity 8 is provided inside the rear side of the base 1, a socket 9 connected to the cavity 8 is provided on the rear inner wall of the relay mounting portion 5, a plug board 10 corresponding to the socket 9 is fixedly connected to the upper rear side of the relay body 2, and an elastic clamping assembly 11 is provided inside the cavity 8, and the elastic clamping assembly 11 is used to fix the plug board 10.

[0034] like Figure 1 and Figure 3 As shown, in this embodiment, a sealing ring 12 is installed inside the installation groove 6, and the sealing ring 12 is located on the outside of the slot 7. The relay body 2 can be smoothly installed inside the installation groove 6 and squeeze the sealing ring 12. The sealing ring 12 can ensure the sealing effect of the plug-in joint, thereby preventing dust or moisture from entering and causing a short circuit at the plug-in joint, thereby improving the safety of the relay during use.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, guide columns 13 are fixedly connected at the four corners of the inner part of the installation groove 6, and guide holes 14 corresponding to the guide columns 13 are opened at the four corners of the lower surface of the relay body 2. During installation, the relay body 2 is aligned with the installation groove 6 on the base 1, and positioning is performed through the cooperation of the guide columns 13 and the guide holes 14 to prevent tilting.

[0036] like Figure 3 and Figure 5As shown, in this embodiment, the socket 9 extends to the bottom of the mounting groove 6, the thickness of the plug plate 10 is the same as the width of the socket 9, and the elastic clamping assembly 11 includes two eccentric clamping blocks 1101 rotatably connected to the inside of the cavity 8, the two eccentric clamping blocks 1101 can approach each other and form a first distance between the two, the first distance is less than the thickness of the plug plate 10, and the two eccentric clamping blocks 1101 can move away from each other and form a second distance between the two, the second distance is greater than the thickness of the plug plate 10, by pressing the relay body 2, the plug plate 10 pushes the two eccentric clamping blocks 1101 to move in the opposite direction around the rotating shaft 1103 and form the second distance, because the second distance is greater than the thickness of the plug plate 10, the relay body 2 can be smoothly installed inside the mounting groove 6.

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, the adjacent ends of the two eccentric clamping blocks 1101 are fixedly connected with a soft pad 1102, and the material of the soft pad 1102 includes but is not limited to rubber, which can improve the friction between the eccentric clamping block 1101 and the plug board 10.

[0038] like Figure 5 and Figure 6 As shown, in this embodiment, the front and rear sides of the eccentric clamping block 1101 are fixedly connected with a rotating shaft 1103, and the rotating shaft 1103 is rotatably connected to the front and rear inner walls of the cavity 8. The outer surface of the rotating shaft 1103 is fixedly connected with a gear 1104, and a pressing component 15 is provided on the base 1. The pressing component 15 is used to make the two gears 1104 rotate in opposite directions, so that the two eccentric clamping blocks 1101 can be brought close to each other through the restoring force of the spring 1504. The first distance formed after approaching each other is less than the thickness of the plug board 10, and the plug board 10 can be firmly fixed even in a vibration environment, thereby ensuring that the relay body 2 is installed on the base 1 more firmly, and can effectively prevent the conductive contact part 3 from escaping from the slot 7, so as to achieve the stability of the signal transmission between the two.

[0039] like Figure 5-8 As shown, in this embodiment, the pressing assembly 15 includes a rack 1501, and the left and right sides of the rack 1501 are meshed with the gear 1104. The upper surface of the rack 1501 is fixedly connected with a rectangular rod 1503, and the top of the rectangular rod 1503 passes through the base 1 and is fixedly connected with a button 1502. The rectangular rod 1503 is slidably connected to the base 1, and the outer surface of the rectangular rod 1503 is sleeved with a spring 1504. When disassembling, pressing the button 1502 drives the rectangular rod 1503 and the rack 1501 to slide downward and compress the spring 1504. The rack 1501 can drive the two gears 1104 to rotate in the opposite direction during the movement. At this time, the gear 1104 drives the rotating shaft 1103 and the two eccentric clamps 1101 away from each other, thereby releasing the plug board 10.

[0040] like Figure 7 and Figure 8 As shown, in this embodiment, a movable rod 1505 is provided at the bottom of the cavity 8, and pin shafts 1506 are fixedly connected to the left and right sides of the movable rod 1505, and the pin shafts 1506 are rotatably connected to the inner walls of the left and right sides of the cavity 8. One end of the movable rod 1505 is located at the bottom of the rack 1501, and the bottom end of the rack 1501 is a round head structure. The other end of the movable rod 1505 passes through the jack 9 and is located on the lower surface of the relay body 2. One end of the movable rod 1505 located on the lower surface of the relay body 2 is rotatably connected to a roller 1507, and an avoidance groove 1508 corresponding to the roller 1507 is provided on the lower surface of the relay body 2. After the rack 1501 moves downward to the bottom, it squeezes the movable rod 1505. At this time, the movable rod 1505 rotates around the pin shaft 1506 and pushes the conductive contact part 3 out of the slot 7 through the roller 1507, so as to facilitate the removal of the relay body 2 from the relay mounting part 5.

[0041] The technical solution provided by the present invention is that during installation, the relay body 2 is aligned with the installation groove 6 on the base 1, and the positioning is performed by the cooperation of the guide column 13 and the guide hole 14. At this time, the plug plate 10 on the relay body 2 is inserted into the inside of the plug hole 9, and then the relay body 2 is continuously pressed. At this time, the plug plate 10 pushes the two eccentric clamping blocks 1101 to move in the opposite direction around the rotating shaft 1103 and form a second distance. Since the second distance is greater than the thickness of the plug plate 10, the relay body 2 can be smoothly installed in the inside of the installation groove 6 and squeeze the sealing ring 12. The sealing effect of the plug-in joint is ensured by the sealing ring 12, thereby preventing dust or moisture from entering and causing a short circuit at the plug-in joint, thereby improving the safety of the relay during use, and since the restoring force of the spring 1504 can make the two eccentric clamping blocks 1101 approach each other, the first distance formed after approaching each other is smaller than the plug plate 10 The thickness can ensure that the plugboard 10 is firmly fixed even in a vibration environment, thereby ensuring that the relay body 2 is installed on the base 1 more firmly, effectively preventing the conductive contact part 3 from escaping from the slot 7, and achieving the stability of the signal transmission between the two. When disassembling, pressing the button 1502 drives the rectangular rod 1503 and the rack 1501 to slide downward and compress the spring 1504. The rack 1501 can drive the two gears 1104 to rotate in the opposite direction during the movement. At this time, the gear 1104 drives the rotating shaft 1103 and the two eccentric clamps 1101 away from each other, thereby releasing the plugboard 10. Then the rack 1501 continues to move downward and squeezes the movable rod 1505. At this time, the movable rod 1505 rotates around the pin shaft 1506 and pushes the conductive contact part 3 out of the slot 7 through the roller 1507, so that the relay body 2 is easy to be disassembled from the relay mounting part 5.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
