[0002] A relay, also known as an electronic relay, is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits and is essentially an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, most existing relays are fixed by squeezing the wire ends with screws. However, over time, the wires may loosen and detach. Therefore, those skilled in the art have provided a relay to prevent wire detachment, in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a relay to prevent wire disconnection. After the terminal block is set on the upper and lower end face of the relay body, the wire harness can be embedded into the terminal block. The fixing block and rubber block set in the terminal block can squeeze and fix the wire harness. At the same time, the movable block can assist in fixing the wire harness under the action of the spring. After the mounting plate is set on the rear end face of the relay body, the relay can be conveniently installed and fixed on the front end face of the fixing plate.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A relay for preventing wire disconnection includes a relay body. A terminal is provided at the midpoint of the upper and lower end faces of the relay body. Four embedded slots are provided on the upper end faces of the two terminal heads. Movable blocks are provided on the upper ends of the front and rear inner walls of the multiple embedded slots. Fixed blocks are provided on the lower ends of the front inner walls of the multiple embedded slots. Four threaded rods are provided on the lower ends of the front faces of the two terminal heads.

[0007] A mounting plate is fixedly installed on the rear end face of the relay body. Snap-fit ​​blocks are fixedly installed on both sides of the mounting plate near the front and lower ends. A fixing plate is installed on the rear end face of the mounting plate. Threaded grooves are opened on both sides of the front end face of the fixing plate near the upper and lower ends. Knobs are installed on both sides of the front end face of the fixing plate near the upper and lower ends.

[0008] Furthermore, springs are fixedly provided on the front end faces of the plurality of movable blocks, and the ends of the plurality of springs away from the movable blocks are fixedly provided on the upper end of the inner wall of the embedded groove.

[0009] Furthermore, two movable blocks located on the same inner wall of the embedding groove are fitted together, and the two terminals are respectively snapped into the midpoint of the upper and lower end faces of the relay body.

[0010] Furthermore, multiple fixing blocks are rotatably sleeved on the outer surface of the threaded rod near the rear end, and rubber blocks are fixedly provided on the rear end face of each of the multiple fixing blocks.

[0011] Furthermore, the plurality of fixing blocks are respectively movably embedded in the lower end of the front inner wall of the plurality of embedding slots, and the plurality of threaded rods are threaded through the front end faces of the two connectors.

[0013] Furthermore, the front end face of the fixing plate is provided with a locking block protruding from the threaded groove, and the four locking blocks are locked onto the outer surfaces of the four locking blocks.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes an anti-derailment relay. After the wiring terminals are snap-fitted and embedded on the upper and lower ends of the relay body, four embedding slots can be opened on the upper ends of the two wiring terminals. The embedded slots allow the wires to be connected to be embedded into the relay body. The embedded slots are equipped with movable fixing blocks and rubber blocks. Rotating the threaded rod connected to the fixing blocks can drive the fixing blocks and rubber blocks to squeeze the wires, thereby squeezing and fixing the wires and preventing them from falling off after long-term use. At the same time, the snap-fit ​​blocks are equipped with movable blocks. The movable blocks are fitted together in pairs under the action of springs. This can prevent dust from entering the embedded slots where no wires are embedded, and can also help fix the embedded wires.

[0016] 2. The present invention proposes an anti-derailment relay, which, after fixing a mounting plate to the rear end face of the relay body, can fix snap-fit ​​blocks on both sides of the mounting plate. The mounting plate can be snapped into the outer surfaces of four snap-fit ​​blocks protruding from the front end face of the fixing plate through the snap-fit ​​blocks. At the same time, the front end face of the fixing plate has a threaded groove at the position of the snap-fit ​​blocks, and a knob is rotatably embedded in the threaded groove. After rotating the embedded knob, the snap-fit ​​blocks can be squeezed, thereby fixing the mounting plate. At the same time, the mounting plate and the relay body can be easily removed by turning the knob. The fixing plate can be installed and fixed in a suitable position on the wall or inside the equipment using bolts. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 6A relay for preventing wire disconnection includes a relay body 5. A terminal 4 is provided at the midpoint of the upper and lower end faces of the relay body 5. Four embedded slots 11 are provided on the upper end faces of the two terminal 4. Movable blocks 9 are provided on the upper end of the front inner wall and the rear inner wall of the multiple embedded slots 11. Fixed blocks 10 are provided on the lower end of the front inner wall of the multiple embedded slots 11. Four threaded rods 7 are provided on the lower end of the front face of the two terminal 4.

[0027] A mounting plate 2 is fixedly installed on the rear end face of the relay body 5. Snap-fit ​​blocks 6 are fixedly installed on both sides of the mounting plate 2 near the front and lower ends. A fixing plate 1 is installed on the rear end face of the mounting plate 2. Threaded grooves 13 are opened on both sides of the front end face of the fixing plate 1 near the upper and lower ends. Knobs 3 are installed on both sides of the front end face of the fixing plate 1 near the upper and lower ends.

[0028] Specifically, after the connector 4 is inserted and mounted on the upper and lower ends of the relay body 5, embedding grooves 11 can be opened on the upper and lower ends of the connector 4. The embedded grooves 11 can better embed the circuit to be connected into the relay body 5. The relay body 5 adopts the existing known conventional technical structure. At the same time, a cover plate is provided on the front of the relay body 5. After the cover plate is removed, the circuit and the relay can be connected with screws. After the fixing block 10 and rubber block 12 are set inside the connector 4, the threaded rod 7 can be rotated, so that the threaded rod 7 drives the fixing block 10 and rubber block 12 to connect the circuit. The relay body 5 is secured by compression. The movable block 9 in the connector 4 can assist in securing the circuit under the action of the spring 8. In the recess 11 where no circuit is embedded, the movable blocks 9 fit together under the action of the spring 8, thus sealing the recess 11 and preventing the circuit from entering the relay. After the mounting plate 2 is fixedly installed on the rear end of the relay body 5, the snap-fit ​​block 6 can be inserted into the front end of the fixing plate 1. The four knobs 3 on the front end of the fixing plate 1 can be rotated to compress the snap-fit ​​block 6, thus facilitating the installation and fixation of the relay body 5.

[0029] Reference Figure 4 Each of the multiple movable blocks 9 has a spring 8 fixedly installed on its front end face, and the ends of the multiple springs 8 away from the movable blocks 9 are fixedly installed on the upper end of the inner wall of the embedded groove 11.

[0030] Specifically, after the spring 8 is fixedly installed between the inner wall of the embedding groove 11 and the movable block 9, the spring 8 can push the movable block 9 to move. When there is a wire embedded in the embedding groove 11, the movable block 9 can squeeze the wire under the push of the spring 8, which plays an auxiliary role in fixing the wire. When there is no wire in the embedding groove 11, the movable block 9 can fit under the push of the spring 8, which can seal the inside of the embedding groove 11 and prevent dust from entering the relay body 5 through the embedding groove 11.

[0031] Reference Figure 3 and Figure 4 Among the multiple movable blocks 9, two movable blocks 9 located on the inner wall of the same embedded groove 11 are attached to each other, and two wire heads 4 are respectively snapped and embedded at the midpoint of the upper and lower end faces of the relay body 5.

[0032] Specifically, after the two movable blocks 9 are fitted together, they can seal and prevent dust from entering the embedded groove 11. After the connector 4 is snapped into the upper and lower surfaces of the relay body 5, the wires can pass through the embedded groove 11 in the connector 4 and connect to the relay body 5.

[0033] Reference Figure 4 and Figure 5 Multiple fixing blocks 10 are rotatably sleeved on the outer surface of the threaded rod 7 near the rear end, and rubber blocks 12 are fixedly installed on the rear end face of each of the multiple fixing blocks 10.

[0034] Specifically, after the fixing block 10 is rotated and sleeved on the outer surface of the threaded rod 7 near the rear end, a rubber block 12 can be fixedly set on the rear end face of the fixing block 10. When the threaded rod 7 drives the movable block 9 and the rubber block 12 to move in position, the fixing block 10 and the rubber block 12 can better squeeze and fix the line.

[0035] Reference Figure 3 and Figure 4 Multiple fixing blocks 10 are respectively movably embedded in the lower end of the front inner wall of multiple embedding slots 11, and multiple threaded rods 7 are threaded through the front end face of two connectors 4.

[0036] Specifically, after the fixing block 10 is movably embedded in the front inner wall of the embedding groove 11, the rotating threaded rod 7 can drive the movable block 9 and the rubber block 12 to move in position, thereby squeezing the wire embedded in the embedding groove 11, thus fixing the wire and preventing it from falling off after long-term use.

[0037] Reference Figure 1 and Figure 6 The four knobs 3 are respectively rotated and embedded in the four threaded grooves 13, and the outer surface of the four knobs 3 is fixedly provided with limit blocks near the rear end.

[0038] Specifically, after the knob 3 is rotated and embedded into the four threaded grooves 13 on the front end face of the fixed plate 1, the knob 3 can be extended and retracted in the threaded grooves 13. After the limit block is fixedly installed on the outer surface of the knob 3 near the rear end, the knob 3 can be prevented from accidentally falling off.

[0039] Reference Figure 2 and Figure 6 The front end face of the fixing plate 1 is provided with a locking block protruding from the threaded groove 13, and four locking blocks 6 are locked onto the outer surface of the four locking blocks.

[0040] Specifically, after a locking block protrudes from the threaded groove 13 on the front end face of the fixing plate 1, it can engage with four fixed locking blocks 6. At the same time, rotating the knob 3 in the threaded groove 13 can press the locking block 6, thus conveniently pressing the locking block 6. This allows the mounting plate 2 and the relay body 5 to be conveniently installed and fixed on the front end face of the fixing plate 1. The fixing plate 1 can also be fixed to a suitable position on the wall or inside the equipment using bolts.

[0041] Working principle: During use, the operator can use bolts to install and fix the fixing plate 1 in a suitable position on the wall or inside the equipment. After fixing the fixing plate 1, the operator can pass the existing connected wires through the terminal 4 set on the upper or lower end face of the relay body 5, embedding the wires into the interior of the relay body 5. After opening the cover plate set on the front face of the relay body 5, the wires and the relay can be connected with screws. After the connection is completed and the cover plate is closed, the operator can rotate the threaded rod 7 set in the terminal 4, so that the threaded rod 7 drives the fixing block 10 and the rubber block 12 to squeeze the wires, thereby fixing the wires. After the wires are fixed, the relay body 5 with the mounting plate 2 fixed can be snapped onto the outer surface of the four protruding clips on the front face of the fixing plate 1. After rotating the knob 3, the knob 3 can squeeze the clip 6, thereby conveniently installing and fixing the relay body 5 on the front face of the fixing plate 1.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
