Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-7 A relay assembly that is easy to install includes a mounting bracket 1 and a relay body 2. The mounting bracket 1 has multiple mounting holes, and a vertical rod 3 is vertically fixedly installed in each of the multiple mounting holes. An L-shaped movable block 4 is vertically slidably mounted on the vertical rod 3. A positioning plate 5 with an L-shaped longitudinal section is fixedly installed at the lower end of the movable block 4. The mounting bracket 1 is installed in the distribution box by bolt fasteners.

[0028] The back of the relay body 2 is fixedly installed with a support block 6 and a locking block 7, both of which have an L-shaped longitudinal section. The support block 6 is placed on the upper end of the fixed frame 1, and the locking block 7 abuts against the positioning plate 5. A first telescopic spring 8 is sleeved on the vertical rod 3. The two ends of the first telescopic spring 8 are fixedly connected to the moving block 4 and the inner wall of the mounting hole, respectively. The first telescopic spring 8 is in a compressed state.

[0029] When installing the relay body 2, the moving block 4 is moved vertically upward, compressing the first telescopic spring 8. As the moving block 4 moves upward, it moves the positioning plate 5 upward. Then, the support block 6 on the relay body 2 is placed on the upper end of the fixing frame 1, and the locking block 7 is placed below the fixing frame 1, so that the relay body 2 contacts the fixing frame 1. Then, the moving block 4 is released. Under the action of the elastic force of the first telescopic spring 8, the moving block 4 will move the positioning plate 5 towards the locking block 7 until the positioning plate 5 contacts the locking block 7. Under the action of the positioning plate 5, the movement of the locking block 7 can be restricted, thereby completing the installation of the relay body 2.

[0030] When disassembly is required, the moving block 4 is moved upward, which in turn causes the positioning plate 5 to separate from the locking block 7. At this time, the locking block 7 is released, and then the support block 6 is removed from the fixing frame 1, thus completing the disassembly of the relay body 2. Both installation and disassembly are relatively convenient and do not require external tools, effectively improving the efficiency of relay disassembly and installation, and making it easier for staff to maintain the relay.

[0031] A limit hole is provided on the support block 6, and a limit rod 9 is vertically fixedly installed on the upper end of the fixing frame 1. One end of the limit rod 9 is inserted into the limit hole. When the support block 6 is placed on the fixing frame 1, one end of the limit rod 9 is inserted into the limit hole. Under the action of the limit rod 9 and the limit hole, the horizontal movement of the relay body 2 on the fixing frame 1 can be restricted.

[0032] Two crossbars 10 are fixedly installed on the side of the mounting bracket 1 near the relay body 2. Both crossbars 10 are in contact with the relay body 2. When the relay body 2 is installed on the mounting bracket 1, the relay body 2 is in contact with the two crossbars 10. Under the action of the crossbars 10, a certain gap can be maintained between the relay body 2 and the mounting bracket 1, so as to facilitate the heat dissipation of the relay body 2 during use.

[0033] The relay body 2 has multiple mounting slots at its wiring points, and each mounting slot has a terminal block 11 fixedly installed in it. The relay body 2 has a threaded hole that communicates with the mounting slot, and a screw 12 is threaded into the threaded hole. A metal plate 13 is provided in the mounting slot, and one end of the screw 12 is rotatably connected to the metal plate 13. When connecting a wire, the relay body 2 inserts one end of the wire between the terminal block 11 and the metal plate 13, and then the screw 12 is rotated with a tool. Under the action of the threaded hole, the screw 12 can drive the metal plate 13 to move towards the terminal block 11 until one end of the wire is clamped between the terminal block 11 and the metal plate 13, thereby completing the wire connection.

[0034] Slide grooves are provided on the inner walls of both sides of the mounting slot. Slide blocks 14 are slidably installed in both slide grooves. Both slide blocks 14 are fixedly connected to the metal plate 13. When the screw 12 rotates, the metal plate 13 will drive the two slide blocks 14 to move in the two slide grooves respectively. Under the action of the slide blocks 14 and the slide grooves, the metal plate 13 can be restricted from rotating together with the screw 12.

[0035] Multiple fine needles 15 are fixedly installed on the lower surface of the metal plate 13. The surface of the terminal block 11 has multiple insertion holes that are respectively opposite to the multiple fine needles 15. When one end of the wire is clamped between the metal plate 13 and the terminal block 11, the multiple fine needles 15 will be inserted into one end of the wire. Under the action of the multiple fine needles 15, the wire can be prevented from falling out between the metal plate 13 and the terminal block 11.

[0036] A dust cover 16 is installed at the mounting slot of the relay body 2 via an elastic component. The surface of the dust cover 16 has a rectangular opening. The elastic component includes two slide rails 17, each mounted on the relay body 2 via mounting blocks, two rectangular blocks 18 respectively slidably sleeved on the two slide rails 17, and two second telescopic springs 19 respectively sleeved on the two slide rails 17. The two ends of the second telescopic springs 19 are fixedly connected to the rectangular blocks 18 and the mounting blocks, respectively. Both rectangular blocks 18 are fixedly connected to the dust cover 16. Under the action of the slide rails 17, the rectangular blocks 18, and the second telescopic springs 19, the dust cover 16 is installed on the relay body 2. The dust cover 16 can move on the slide rails 17 via the rectangular blocks 18, thereby opening the mounting slot. Under the elastic force of the second telescopic springs 19, the dust cover 16 can initially block the opening of the mounting slot, reducing dust falling onto the connection between the wire and the relay body 2, thus improving safety.

[0037] In this invention, when installing the relay body 2, the moving block 4 is moved vertically upward, compressing the first telescopic spring 8. As the moving block 4 moves upward, it moves the positioning plate 5 upward. Then, the support block 6 on the relay body 2 is placed on the upper end of the fixing frame 1, and the locking block 7 is placed below the fixing frame 1, so that the relay body 2 contacts the fixing frame 1. Then, the moving block 4 is released. Under the action of the elastic force of the first telescopic spring 8, the moving block 4 will move the positioning plate 5 towards the locking block 7 until the positioning plate 5 contacts the locking block 7. Under the action of the positioning plate 5, the movement of the locking block 7 can be restricted, thereby completing the installation of the relay body 2.

[0038] When disassembly is required, the moving block 4 is moved upward, which in turn causes the positioning plate 5 to separate from the locking block 7. At this time, the locking block 7 is released, and then the support block 6 is removed from the fixing frame 1, thus completing the disassembly of the relay body 2. Both installation and disassembly are relatively convenient and do not require external tools, effectively improving the efficiency of relay disassembly and installation, and making it easier for staff to maintain the relay.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
