Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a quick-release relay terminal structure. Background Technology

[0002] In modern communication systems, relays are used for signal switching and routing. In mobile base stations, relays select and switch signals from different frequency bands to meet the communication needs of different user equipment. Relay terminals are often troublesome to install and remove wires, so quick-release relay terminal structures are needed.

[0003] Quick-release relay terminal blocks are made of highly conductive metal materials and copper alloys, serving as a bridge connecting external wires and the internal circuitry of the relay. They have multiple internal channels to guide current flow. Currently, spring-clip type terminals are common in quick-release relays. However, after repeated insertion and removal of wires, the spring clips are prone to elastic fatigue, resulting in a decrease in clamping force. Existing solutions incorporate a preload adjustment mechanism into the terminal block design to appropriately increase the clamping force after spring clip fatigue. However, this adjustment mechanism occupies space and can cause spatial interference during wire removal, making it difficult to pull out the wire smoothly and significantly reducing the convenience of quick disassembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-release relay terminal structure, which aims to improve the problem that the adjustment structure itself occupies a certain space in the prior art, causing spatial interference when disassembling the wires, making it difficult to pull out the wires smoothly, and greatly reducing the convenience of quick disassembly.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-release relay terminal structure, including a relay body. A mounting block is provided on the top left side of the relay body. Two fixing blocks are fixedly connected to the front and rear ends of the bottom right side of the outer wall of the mounting block. A connecting rod is fixedly connected to an adjacent side of each of the two fixing blocks. A connecting plate is rotatably connected to the outer wall of the connecting rod. Two engaging pieces are fixedly connected to the front and rear sides of the outer wall of the connecting plate. A fixing plate is fixedly connected to the top left side of the relay body. Two engaging grooves are opened on the front and rear ends of the top right side of the fixing plate. A screw is provided at the top of each of the two engaging grooves. The two engaging grooves engage with the engaging pieces. A clamping mechanism is provided on the inner wall of the relay body for clamping the terminal.

[0006] As a further description of the above technical solution:

[0007] The clamping mechanism includes multiple sliding columns, the outer walls of which are slidably connected to the inner wall of the relay body. Each of the multiple sliding columns has a spring on its outer wall, and the ends of the multiple springs that are furthest from each other are fixedly connected to the inner wall of the relay body. Each of the multiple springs has a clamping plate fixedly connected to an adjacent side, and each of the clamping plates has a rotating wheel rotatably connected to its outer wall.

[0008] As a further description of the above technical solution:

[0009] Multiple connecting pieces are fixedly connected to the outer wall of the relay body, and screws are threaded onto the outer wall of each connecting piece.

[0010] As a further description of the above technical solution:

[0011] Two connecting pieces are fixedly connected to the bottom left and right sides of the relay body, and screws are threaded onto the outer walls of the two connecting pieces.

[0012] As a further description of the above technical solution:

[0013] A warning plate is provided on the front side of the relay body, and an anti-electric shock mark is fixedly connected to the front side of the warning plate.

[0014] As a further description of the above technical solution:

[0019] A second connecting groove is provided on the front side of the outer wall of the relay body, and the inner wall of the second connecting groove is fixedly connected to the warning plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when it is necessary to fix the wiring terminal, rotate the connecting plate to align the locking piece with and insert it into the locking groove on the top left side fixing plate of the relay body. This can initially fix the wiring terminal. Then, install a screw on the top of the locking groove and apply pressure to the locking piece by unscrewing the screw pair. This further enhances the connection stability between the locking piece and the locking groove, ensuring that the wiring terminal is firmly fixed on the relay body. When disassembling, simply unscrew the screw and rotate the connecting plate to disengage the locking piece from the locking groove. The operation is simple and quick.

[0022] 2. In this utility model, the outer walls of multiple sliding columns are slidably connected to the relay body, which ensures the stability of the movement of the clamping plate and provides accurate guidance for the clamping of objects. When the object is placed between the clamping plates, the spring generates a reverse force due to compression, which makes the clamping plate tightly clamp the object and ensures a stable connection. At the same time, the rotating wheel on the outer wall of the clamping plate greatly reduces friction when clamping the object, making the insertion and removal of the object smoother.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a quick-release relay terminal structure, including a relay body 1. A mounting block 3 is provided on the top left side of the relay body 1. Two fixing blocks 4 are fixedly connected to the front and rear ends of the bottom right side of the outer wall of the mounting block 3. A connecting rod 5 is fixedly connected to the adjacent side of the two fixing blocks 4. A connecting plate 6 is rotatably connected to the outer wall of the connecting rod 5. Two locking pieces 7 are fixedly connected to the front and rear sides of the outer wall of the connecting plate 6. A fixing plate 8 is fixedly connected to the top left side of the relay body 1. Two locking grooves 9 are opened on the front and rear ends of the top right side of the fixing plate 8. A screw 10 is provided on the top of the two locking grooves 9. The two locking grooves 9 engage with the locking pieces 7. A clamping mechanism 2 is provided on the inner wall of the relay body 1. The clamping mechanism 2 is used to clamp the terminal.

[0032] Specifically, a mounting block 3 is provided on the top left side of the relay body 1. Two fixing blocks 4 are firmly fixedly connected to the front and rear ends of the bottom right side of the outer wall of the mounting block 3. A connecting rod 5 is cleverly fixedly connected to the adjacent side of the two fixing blocks 4. The outer wall of the connecting rod 5 is rotatably connected to a connecting plate 6. Two locking pieces 7 are firmly fixedly connected to the front and rear sides of the outer wall of the connecting plate 6. At the same time, a fixing plate 8 is also fixedly connected to the top left side of the relay body 1. Two locking grooves 9 are carefully opened at the front and rear ends of the top right side of the fixing plate 8. Each locking slot 9 has a screw 10 conveniently located on its top. The locking slot 9 engages with the locking piece 7, allowing the relay to be installed by aligning the locking piece 7 on the connecting plate 6 with the locking slot 9 on the fixing plate 8. The connecting plate 6 is then rotated to engage the locking piece 7 into the locking slot 9, and the screw 10 is used for further securing, ensuring a strong connection. During disassembly, the screw 10 is loosened and removed, and the connecting plate 6 is rotated to disengage the locking piece 7 from the locking slot 9, enabling quick disassembly and greatly improving the ease of use and maintenance efficiency of the relay.

[0033] Reference Figure 5The clamping mechanism 2 includes multiple sliding columns 201. The outer walls of the multiple sliding columns 201 are slidably connected to the inner wall of the relay body 1. The outer walls of the multiple sliding columns 201 are provided with springs 202. The far ends of the multiple springs 202 are fixedly connected to the inner wall of the relay body 1. The adjacent sides of the multiple springs 202 are fixedly connected with clamping plates 203. The outer walls of the multiple clamping plates 203 are rotatably connected with rotating wheels 204.

[0034] Specifically, when it is necessary to clamp and fix the wire, the wire is placed between the clamping plates 203. Since the outer walls of the sliding columns 201 are smoothly slidably connected to the inner wall of the relay body 1, under the squeezing force of the wire, the clamping plates 203 will push the sliding columns 201 to slide on the inner wall of the relay body 1. At this time, the spring 202 fixedly connected to the side adjacent to the clamping plate 203 will be compressed. After the spring 202 is compressed, it will generate a reverse elastic force. This elastic force will act on the clamping plate 203, so that the clamping plate 203 tightly clamps the wire. The outer walls of the clamping plates 203 are rotatably connected to the rotating wheels 204. When the wire needs to move while it is clamped, the rotating wheels 204 will rotate with the movement of the wire, which greatly reduces the friction between the wire and the clamping plate 203, making the movement of the wire smoother.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Multiple connecting pieces 11 are fixedly connected to the outer walls of the relay body 1, and screws 12 are threadedly connected to the outer walls of the multiple connecting pieces 11; two connecting pieces 13 are fixedly connected to the bottom left and right sides of the relay body 1, and screws 14 are threadedly connected to the outer walls of the two connecting pieces 13; a warning plate 15 is provided on the front side of the relay body 1, and an anti-electric shock sign 16 is fixedly connected to the front side of the warning plate 15.

[0036] Specifically, when it is necessary to fix the relay body 1 in a specific position or connect it with other components, the screw 12 is screwed into the threaded hole of the connecting piece 11, and the screw 12 is threadedly connected to the connecting piece 11 to achieve a firm fixation. In specific installation scenarios, the screw 14 is screwed into the threaded hole of the connecting piece 13 to further fix the relay body 1 in the required position and connect it with other structures. The design of the two connecting pieces 13 provides a reliable way for the bottom connection of the relay body 1. The warning plate 15 can visually attract people's attention and remind them that the device is a relay and there is an electrical hazard. The anti-electric shock sign 16 more clearly marks the electrical hazard and prevents people from touching the relay body 1 without knowing it and causing an electric shock accident.

[0037] Reference Figure 2 , Figure 3 and Figure 4 A connecting groove 17 is provided on the top left side of the front end of the relay body 1, and an indicator light 18 is fixed on the inner wall of the connecting groove 17; multiple connecting pieces 19 are fixedly connected to the outer walls of the mounting block 3, and the outer walls of the multiple connecting pieces 19 are threadedly connected to the top left side of the relay body 1; a connecting groove 20 is provided on the front side of the outer wall of the relay body 1, and the inner wall of the connecting groove 20 is fixedly connected to the warning plate 15.

[0038] Specifically, indicator light 18 is fixed to the inner wall of connecting groove 17. When the relay is working, indicator light 18 displays the working status of the relay through different states. Mounting block 3 is threaded to the top left side of relay body 1 through multiple connecting pieces 19 fixed around its outer wall. This connection method is firm and reliable, ensuring a stable connection between mounting block 3 and relay body 1. Connecting groove 20 on the front side of the outer wall of relay body 1 provides a fixed position for warning plate 15. Warning plate 15 is fixed to the inner wall of connecting groove 20, serving as a safety warning.

[0039] Working principle: The mounting block 3 is located on the top left side of the relay body 1. The fixing blocks 4 at the front and rear ends of the bottom right side of the outer wall of the mounting block 3 provide support and connection. The connecting rod 5 between the two fixing blocks 4 provides a fulcrum for the rotation of the connecting plate 6. When it is necessary to fix the wiring terminals, rotate the connecting plate 6 so that the engaging pieces 7 on the front and rear sides of the outer wall of the connecting plate 6 are aligned with the engaging grooves 9 on the top left side of the fixing plate 8 of the relay body 1. Then, the engaging pieces 7 are inserted into the engaging grooves 9. At this time, the engaging pieces 7 and the engaging grooves 9 are engaged, which initially achieves the fixation of the mounting block 3 and its related wiring terminals. Then, in the engagement... Screw 10 is installed at the top of slot 9. Screw 10 applies pressure to the locking piece 7 when screwed down, which further enhances the connection stability between the locking piece 7 and the locking slot 9, ensuring that the terminal block is firmly fixed to the relay body 1. When disassembly is required, simply unscrew screw 10 at the top of the locking slot 9 to release the pressure on the locking piece 7, and then rotate the connecting plate 6 to disengage the locking piece 7 from the locking slot 9. This allows for quick disassembly, making the installation and disassembly of the relay terminal block simple and fast, improving work efficiency, and ensuring the stability and reliability of the terminal block during use.

[0040] Furthermore, the outer walls of multiple sliding posts 201 are slidably connected to the inner wall of the relay body 1, allowing the sliding posts 201 to move within a certain range within the relay body 1. Each sliding post 201 has a spring 202 on its outer wall, with the furthest ends of the springs 202 fixedly connected to the inner wall of the relay body 1. When no external force is applied, the springs 202 are in their natural state. Clamping plates 203 are fixedly connected to adjacent sides of each spring 202. When an object needs to be clamped, it is placed in one of the clamps. Between the plates 203, the object exerts a squeezing force on the clamping plate 203, causing the clamping plate 203 to drive the sliding column 201 to slide on the inner wall of the relay body 1, while compressing the spring 202. Since the spring 202 has an elastic restoring force, the spring 202 will exert a reverse force on the clamping plate 203, so that the clamping plate 203 tightly clamps the object. The outer walls of the multiple clamping plates 203 are rotatably connected to rotating wheels 204. The rotating wheels 204 reduce friction when clamping the object, making the insertion and removal of the object smoother.

[0041] 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.
