Description

Technical Field

[0001] This utility model relates to the field of waterproof quick coupling technology, and in particular to a waterproof quick coupling for Siemens switches. Background Technology

[0002] In the field of electrical connections, especially in applications involving industrial automation, communication equipment, and home appliances, waterproof quick connectors are becoming increasingly important as a key electrical connection component. Waterproof quick connectors are mainly used to enable the quick connection and disconnection of wires or cables, while ensuring stable electrical connections and good waterproof performance in various harsh environments.

[0003] Existing waterproof quick-connect couplings mainly use screws for fixing and connecting wires. Screws rely on manual tightening of screws, but during long-term use, screws may gradually loosen due to vibration, external force, or material fatigue, leading to unstable wire connections and affecting the reliability of electrical connections. Therefore, those skilled in the art provide a Siemens switch waterproof quick-connect coupling to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof quick connector for Siemens switches. The limiting structure uses a limiting block to limit the limiting post, preventing accidental detachment and ensuring that the wires will not loosen or fall off during connection. After the limiting plate is placed into the connection groove, the rotating plate is squeezed by the sliding groove, compressing the spring and preventing the limiting post from rotating due to external force, further improving the safety of the connection. This avoids the loosening problem that may occur with traditional screw limiting, improving the reliability of the connection. At the same time, the operation is simple and quick, facilitating rapid replacement of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Siemens waterproof quick connector, including a junction box, wherein the rear end face of the junction box has four limiting structures arranged in a rectangular pattern; Taking the limiting structure at the upper end near one side as an example, the limiting structure includes a limiting groove located at the rear center of the junction box. A circular groove is provided at the upper center of the rear end face of the junction box near one side. Sliding grooves are provided at the center of the upper and lower inner sidewalls of the circular groove. The circular groove and the sliding groove both penetrate the rear end face of the junction box and lead to the interior of the limiting groove. A circular hole groove is provided at the rear end near one side of the center of the upper end face of the junction box. The circular hole groove penetrates the upper end face of the junction box and leads to the interior of the limiting groove. A limiting post is rotatably connected inside the limiting groove and the circular groove. A limiting block is provided at the front center of the outer two sides of the limiting post. A connecting groove is provided at the center of the rear end face of the limiting post. A limiting plate is provided inside the connecting groove. A rectangular groove is provided at the upper and lower center of the rear end face of the limiting plate. A rotating plate is inclinedly arranged inside the two rectangular grooves. A spring is provided between the inclined surface of the two rotating plates and one inner sidewall of the two rectangular grooves. The above technical solution involves inserting the wire into the limiting groove through a circular slot, then inserting the limiting post into the limiting groove from the opening of the circular slot. Simultaneously, the limiting block slides from inside the sliding groove into the limiting groove, compressing and limiting the wire. The limiting post is then rotated, and the limiting block further restricts its movement. Next, the limiting plate is placed into the connecting groove. The rotating plate is compressed by the sliding groove, thus compressing the spring and preventing the limiting post from rotating due to external force. To remove the wire, simply press the two rotating plates to compress the spring and remove the limiting plate. Then, rotate the limiting post to remove the limiting block through the sliding groove, releasing the restriction. The limiting structure, through the limiting block, restricts the limiting post, preventing accidental detachment and ensuring the wire does not loosen or fall off during connection. After the limiting plate is placed in the connecting groove, the rotating plate is compressed by the sliding groove, compressing the spring and preventing the limiting post from rotating due to external force, further improving connection safety and avoiding the loosening problems that may occur with traditional screw-based limiting systems. This enhances connection reliability and is simple and quick to operate, facilitating rapid device replacement.

[0006] Furthermore, the rear end face of the junction box has four cable outlet slots arranged in a rectangle. All four cable outlet slots pass through the rear end face of the junction box and lead to the interior of four circular slots. A waterproof plate is provided at the center of both the upper and lower end faces of the junction box. Threaded nails are threadedly connected to the center of the upper end face of the waterproof plate near the top and the center of the lower end face of the waterproof plate near the bottom. With the above technical solution, after the wires are fixed by the limiting structure, the wires are pressed and attached to the wire outlet groove. Then, the waterproof plate is fixed to the upper and lower ends of the junction box with threaded nails. The wires are pressed and attached through the wire outlet groove, which reduces mutual interference between wires and reduces electromagnetic interference in signal transmission. The threaded connection between the waterproof plate and the junction box ensures the tightness of the connection, effectively preventing moisture and dust from entering the junction box and improving the safety of electrical connection.

[0007] Furthermore, a fixing plate is provided at the center of the front end face of the junction box, and four circular holes are arranged in a rectangle at the center of the rear end face of the fixing plate. Buckles are provided at the top and bottom of the center of both sides of the fixing plate. The above technical solution uses four circular holes on the fixing plate to fix the entire device, thereby improving the stability of the device.

[0008] Furthermore, a switch device is provided at the center of the front end face of the fixing plate; The above technical solution allows for the control of power supply usage and disconnection via a switching device, making it convenient to use.

[0009] Furthermore, an outer shell is fitted onto the outer center of the fixing plate near the front; The above technical solution protects the exterior of the device body with an outer shell, preventing internal damage caused by external forces.

[0010] Furthermore, both the limiting groove and the sliding groove are circular, and the radius of the limiting groove is larger than that of the sliding groove; With the above technical solution, since the radius of the limiting groove is larger than that of the sliding groove, the limiting block can accurately enter the interior of the limiting groove when it slides in the sliding groove, thus achieving a reliable limiting effect.

[0011] Furthermore, the limiting block is fitted inside the limiting groove; Through the above technical solution, the wire is squeezed due to the tight fit between the limiting block and the limiting groove, thus preventing the wire from falling off due to external force.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the Siemens switch waterproof quick connector limiting structure limits the limiting post by limiting the limiting block to prevent the limiting post from accidentally falling off, ensuring that the wire will not loosen or fall off during the connection process. After the limiting plate is placed into the connection groove, the rotating plate is squeezed by the sliding groove, compressing the spring and preventing the limiting post from rotating due to external force, which further improves the safety of the connection, avoids the loosening problem that may occur with traditional screw limiting, improves the reliability of the connection, and at the same time, the operation is simple and quick, and it is convenient to quickly replace the device.

[0013] 2. In this utility model, the wires are pressed and attached through the wire outlet groove, which reduces mutual interference between the wires and reduces electromagnetic interference in signal transmission. The threaded connection between the waterproof plate and the junction box ensures the tightness of the connection, effectively preventing moisture and dust from entering the junction box and improving the safety of the electrical connection.

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.

[0017] Reference Figure 1-4 One embodiment of this utility model is a Siemens waterproof quick connector, which includes a junction box 1. The rear end face of the junction box 1 has four limiting structures 2 arranged in a rectangular shape.

[0018] like Figure 2 , 3As shown in Figure 4, taking the limiting structure 2 at the upper end near one side as an example, the limiting structure 2 includes a limiting groove 201, which is located at the rear center of the junction box 1. A circular groove 202 is provided at the upper end near one side of the center of the rear end face of the junction box 1. Sliding grooves 203 are provided at the center of the upper and lower inner side walls of the circular groove 202. Both the circular groove 202 and the sliding groove 203 penetrate the rear end face of the junction box 1 and lead to the interior of the limiting groove 201. A circular hole groove 204 is provided at the rear end near one side of the center of the upper end face of the junction box 1. The circular hole groove 204 penetrates the upper end face of the junction box 1 and leads to the interior of the limiting groove 201. The limiting groove 201 and the circular hole groove 204... A limiting post 205 is rotatably connected inside the groove 202. Limiting blocks 206 are provided at the front center of the outer two sides of the limiting post 205. A connecting groove 207 is provided at the center of the rear end face of the limiting post 205. A limiting plate 208 is provided inside the connecting groove 207. Rectangular grooves 209 are provided at the upper and lower center of the rear end face of the limiting plate 208. A rotating plate 210 is inclinedly arranged inside each of the two rectangular grooves 209. A spring 211 is provided between the inclined surface of the two rotating plates 210 and one inner sidewall of each of the two rectangular grooves 209. The wire is inserted into the limiting groove 201 through the circular hole groove 204, and then the limiting post 206 is... 05 enters the limiting groove 201 through the opening of the circular groove 202, while the limiting block 206 slides from inside the sliding groove 203 into the limiting groove 201 to compress and limit the wire. Then, the limiting post 205 is rotated and limited by the limiting block 206. Next, the limiting plate 208 is placed into the connecting groove 207. The rotating plate 210 is compressed by the sliding groove 203, thereby compressing the spring 211 to prevent the limiting post 205 from rotating due to external force. When removing the wire, simply press the two rotating plates 210 to compress the spring 211 to remove the limiting plate 208, and then rotate the limiting post 205. The limiting block 206 is removed through the sliding groove 203 to release the limiting position. The limiting structure 2 limits the limiting post 205 through the limiting block 206 to prevent the limiting post 205 from accidentally falling off, ensuring that the wire will not loosen or fall off during the connection process. After the limiting plate 208 is placed into the connecting groove 207, the rotating plate 210 is squeezed by the sliding groove 203, compressing the spring 211 to prevent the limiting post 205 from rotating due to external force, which further improves the safety of the connection, avoids the loosening problem that may occur with traditional screw limiting, improves the reliability of the connection, and is simple and quick to operate, making it easy to quickly replace the device.

[0019] like Figure 2As shown, the rear end face of the junction box 1 has four rectangular cable outlet slots 3. All four cable outlet slots 3 pass through the rear end face of the junction box 1 and lead to the interior of four circular slots 204. Waterproof plates 4 are provided at the center of the upper and lower end faces of the junction box 1. Threaded nails 5 are threadedly connected to the center of the upper end face of the waterproof plate 4 and the center of the lower end face of the waterproof plate 4. After the wire has been fixed by the limiting structure 2, the wire is pressed against the cable outlet slot 3, and then the waterproof plate 4 is fixed to the upper and lower end faces of the junction box 1 by the threaded nails 5. The wire is pressed against the cable outlet slot 3, which reduces mutual interference between the wires and reduces electromagnetic interference in signal transmission. The threaded connection between the waterproof plate 4 and the junction box 1 ensures the tightness of the connection and effectively prevents moisture and dust from entering the interior of the junction box 1, thereby improving the safety of the electrical connection.

[0020] A fixing plate 6 is provided at the center of the front face of the junction box 1. Four circular holes 7 are arranged in a rectangle at the center of the rear face of the fixing plate 6. Buckles 8 are provided at the top and bottom of the center of both sides of the fixing plate 6. The entire device is fixed through the four circular holes 7 on the fixing plate 6 to improve the stability of the device.

[0021] A switch device 9 is provided at the center of the front end face of the fixing plate 6. The power supply can be controlled and cut off through the switch device 9, which is convenient to use.

[0022] A housing 10 is fitted around the center of the outer side of the fixing plate 6. The housing 10 protects the exterior of the device body and prevents external forces from causing internal damage.

[0023] Both the limiting groove 201 and the sliding groove 203 are circular, and the radius of the limiting groove 201 is larger than that of the sliding groove 203. Since the radius of the limiting groove 201 is larger than that of the sliding groove 203, when the limiting block 206 slides in the sliding groove 203, it can accurately enter the interior of the limiting groove 201 to achieve a reliable limiting effect.

[0024] The limiting block 206 is attached to the inside of the limiting groove 201. Due to the tight fit between the limiting block 206 and the limiting groove 201, the wire is squeezed to prevent it from falling off due to external force.

[0025] Working principle: The wire is inserted into the limiting groove 201 through the circular slot 204. Then, the limiting post 205 is inserted into the limiting groove 201 from the opening of the circular slot 202. At the same time, the limiting block 206 slides from the sliding groove 203 into the limiting groove 201 to squeeze and limit the wire. Then, the limiting post 205 is rotated and limited by the limiting block 206. Then, the limiting plate 208 is placed into the connecting groove 207. The rotating plate 210 is squeezed by the sliding groove 203, thereby compressing the spring 211 and preventing the limiting post 205 from rotating due to external force.

[0026] When disconnecting the wire, simply press the two rotating plates 210 to compress the spring 211, thereby removing the limiting plate 208. Then, rotate the limiting post 205 to remove the limiting block 206 through the sliding groove 203, thus releasing the limiting position. The limiting structure 2 limits the limiting post 205 through the limiting block 206, preventing the limiting post 205 from accidentally falling off and ensuring that the wire will not loosen or fall off during the connection process. After the limiting plate 208 is placed into the connection groove 207, the rotating plate 210 is pressed by the sliding groove 203, compressing the spring 211 and preventing the limiting post 205 from rotating due to external force, further improving the safety of the connection and avoiding [further issues]. The traditional screw-based limit mechanism can loosen, improving connection reliability. It is also simple and quick to operate, facilitating rapid device replacement. After the wire is fixed by the limit structure 2, press the wire into the cable tray 3, and then fix the waterproof plate 4 to the upper and lower ends of the junction box 1 using threaded nails 5. The wire is pressed into place through the cable tray 3, reducing mutual interference between wires and lowering electromagnetic interference in signal transmission. The threaded connection between the waterproof plate 4 and the junction box 1 ensures a tight connection, effectively preventing moisture and dust from entering the junction box 1 and improving the safety of the electrical connection.

[0027] 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.
