Abstract
Description
Technical Field
[0001] This utility model relates to the field of relay protection panel technology, specifically to a relay protection panel cable fixing device. Background Technology
[0002] A relay protection panel is a metal cabinet that houses secondary equipment such as relay protection devices, measurement and control devices, operating handles, pressure plates, terminal blocks, and auxiliary power supplies. It integrates protection, measurement, control, signaling, and communication functions to perform real-time monitoring, fault diagnosis, and rapid disconnection of primary equipment in a power system (such as transformers, lines, busbars, and capacitors). When faults such as overcurrent, short circuit, grounding, overvoltage, undervoltage, or differential faults occur in the system, the relay protection panel can automatically issue trip commands to isolate the fault area, prevent the accident from escalating, and ensure the safe operation of the power grid. The relay protection panel cable is used as the transmission medium.
[0003] However, existing cable fixing devices for relay protection panels have the following disadvantages:
[0004] (1) The existing cable fixing device of the relay protection panel has a weak clamping and fixing function. When the existing cable is processed or installed, the threaded rod is rotated to drive the clamping plate to clamp the cable. The clamping process requires multiple rotations of the threaded rod, which takes a long time and cannot quickly disassemble and install the cable.
[0005] (2) The existing cable fixing device of the relay protection panel has a weak fixing function. When the existing cable is installed, the device cannot be fixed well to the surface of the object. The device may shake during cable processing and cannot stably clamp and fix the cable. Utility Model Content
[0006] The purpose of this utility model is to provide a cable fixing device for a relay protection panel to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable fixing device for a relay protection panel, comprising a clamping and fixing assembly and a stable connection assembly. The clamping and fixing assembly consists of a base, a limiting plate, a clamping plate, a locking block, a limiting frame, a connecting frame, a pull rod, and a first spring. The limiting plate is fixedly connected to the inner bottom wall of the base, and a clamping plate is provided above the limiting plate. The limiting plate is provided with a limiting frame, and a locking block is fixedly connected to the inner side wall of the limiting frame. A connecting frame is fixedly connected to one side of the clamping plate, and a pull rod is provided on one side of the connecting frame. A first spring is installed on the surface of the pull rod.
[0008] The stable connection assembly consists of a connecting plate, a limiting rod, a second spring, a clamping plate, and a magnetic strip. The bottom end of the base is fixedly connected to the connecting plate, the inner wall of the connecting plate is provided with a limiting rod, the surface of the limiting rod is installed with a second spring, the bottom end of the connecting plate is fixedly connected with a magnetic strip, and the surface of the limiting rod is provided with a clamping plate above the second spring.
[0009] Optionally, the inner walls of the limiting plate and the clamping plate are provided with anti-slip pads, and the surface of the anti-slip pads is provided with anti-slip textures. The installation of the anti-slip pads can increase friction when clamping the cable and prevent the cable from shaking.
[0010] Optionally, a rubber pad is fixedly connected to the top of the card plate, and anti-slip particles are installed on the top of the rubber pad. The installation of the rubber pad can increase friction when the card plate is in contact with the bottom edge of the table, thus preventing the connecting plate from shaking.
[0011] Optionally, there are two magnetic strips, which are symmetrically distributed. The symmetrical distribution of the magnetic strips can be used to increase the adsorption range of the device.
[0012] Optionally, the locking block is located on the inner wall of the connecting block, and the locking block is located on one side of the pull rod. The locking block being located on one side of the pull rod facilitates the engagement of the pull rod with the locking block.
[0013] Optionally, a handle is fixedly connected to the top of the connecting plate. The handle is square, and holding the handle makes it easy to pull the magnetic strip off the metal tabletop when the connecting plate is pulled out.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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.
[0023] Please see Figures 1-4As shown, this utility model provides a technical solution: a cable fixing device for a relay protection panel, including a clamping and fixing assembly 1 and a stable connection assembly 2. The clamping and fixing assembly 1 consists of a base 101, a limiting plate 102, a clamping plate 103, a locking block 104, a limiting frame 105, a connecting frame 106, a pull rod 107, and a first spring 108. The limiting plate 102 is fixedly connected to the inner bottom wall of the base 101. The clamping plate 103 is arranged above the limiting plate 102. The limiting plate 102 is provided with a limiting frame 105. The locking block 104 is fixedly connected to the inner side wall of the limiting frame 105. The connecting frame 106 is fixedly connected to one side of the clamping plate 103. The pull rod 107 is arranged on one side of the connecting frame 106. The first spring 108 is installed on the surface of the pull rod 107. The base 101 is fixed to the limiting plate 102, and the cable can be placed into the limiting plate 102 and the clamping plate. Inside 103, press down on the clamping plate 103. The limiting frame 105 fixed by the limiting plate 102 can be connected to the locking block 104, which can fit with the pull rod 107. The connecting frame 106 is used to limit the pull rod 107. When the pull rod 107 fits with the locking block 104, the first spring 108 can push the pull rod 107 to fit with the locking block 104. Since the locking block 104 and the pull rod 107 are facing opposite directions, they can be locked together and the clamping plate 103 can be fixed to the top of the cable. When the cable needs to be removed, hold the pull rod 107 and pull it to one side to lift the clamping plate 103 upward, and the cable can be removed. The clamping and fixing component 1 ensures the stability of the cable clamping and is convenient and simple to operate when clamping and disassembling, improving work efficiency. One side of the locking block 104 is provided with several equilateral triangles, and one side of the pull rod 107 is shaped like an inverted triangle, which can be locked together with the locking block 104.
[0024] The stable connection assembly 2 consists of a connecting plate 201, a limiting rod 202, a second spring 203, a clamping plate 204, and a magnetic strip 205. The bottom end of the base 101 is fixedly connected to the connecting plate 201. The inner wall of the connecting plate 201 is provided with a limiting rod 202. The surface of the limiting rod 202 is mounted with a second spring 203. The bottom end of the connecting plate 201 is fixedly connected to the magnetic strip 205. The surface of the limiting rod 202 is provided with a clamping plate 204 above the second spring 203. When the connecting plate 201 is placed on the edge of the table, the clamping plate 204 can be clamped at the bottom end of the edge of the table. The second spring 203 can push the clamping plate 204 to clamp and fix it to the table. The magnetic strip 205 can magnetically attract the metal table, further stabilizing and fixing the device, thereby ensuring the stability of the device when processing cables.
[0025] The inner walls of the limiting plate 102 and the clamping plate 103 are provided with anti-slip pads 3. The surface of the anti-slip pads 3 is provided with anti-slip textures. The installation of the anti-slip pads 3 can increase the friction when clamping the cable and prevent the cable from shaking.
[0026] A rubber pad 4 is fixedly connected to the top of the card plate 204. Anti-slip particles are installed on the top of the rubber pad 4. The installation of the rubber pad 4 can increase the friction when the card plate 204 is in contact with the bottom edge of the table, thus preventing the connecting plate 201 from shaking.
[0027] There are two magnetic strips 205, which are symmetrically distributed. The symmetrical distribution of the magnetic strips 205 can be used to increase the adsorption range of the device.
[0028] The locking block 104 is located on the inner wall of the connecting block and on one side of the pull rod 107. The locking block 104 being located on one side of the pull rod 107 facilitates the engagement of the pull rod 107 with the locking block 104.
[0029] A handle 5 is fixedly connected to the top of the connecting plate 201. The handle 5 is square. Holding the handle 5 makes it easy to pull the magnetic strip 205 out of the metal table when the connecting plate 201 is pulled out.
[0030] In this invention, the working steps of the device are as follows:
[0031] First step: The base 101 is fixed to the limiting plate 102. The cable can be placed into the limiting plate 102 and the clamping plate 103, and the clamping plate 103 is pressed down. The limiting frame 105 fixed to the limiting plate 102 is connected to the locking block 104, which can fit with the pull rod 107. The connecting frame 106 is used to limit the pull rod 107. When the pull rod 107 fits with the locking block 104, the first spring 108 can push the pull rod 107 to fit with the locking block 104. Since the locking block 104 and the pull rod 107 are facing opposite directions, they can be locked together and the clamping plate 103 is fixed to the top of the cable. When it is necessary to remove the cable, hold the pull rod 107 and pull it to one side to lift the clamping plate 103 upward, and the cable can be removed. The clamping and fixing component 1 ensures the stability of the cable clamping and is convenient and simple to operate when clamping and disassembling, thus improving work efficiency.
[0032] The second step: Place the connecting plate 201 on the edge of the table. The clamping plate 204 can be clamped at the bottom of the edge of the table. The second spring 203 can push the clamping plate 204 to clamp and fix it to the table. The magnetic strip 205 can magnetically attract the metal table, further stabilizing and fixing the device, thereby ensuring the stability of the device when processing cables.
[0033] The third step: The installation of the anti-slip pad 3 can increase the friction when clamping the cable and prevent the cable from shaking. The installation of the rubber pad 4 can increase the friction when the clamping plate 204 is attached to the bottom edge of the tabletop and prevent the connecting plate 201 from shaking. The hand handle 5 can facilitate the pulling of the magnetic strip 205 from the metal tabletop when the connecting plate 201 is pulled out.
