Description

Technical Field

[0001] This utility model relates to the field of plug inner frame technology, and in particular to a plug inner frame that facilitates wire clamping. Background Technology

[0002] The plug inner frame is a device used to fix the conductive metal plug installed inside the plug, so that the conductive metal plug is properly fitted and fixed inside the plug inner frame, thereby making the conductive metal plug perform better.

[0003] Existing plug inner frames often rely on adhesive to secure the plug, which is inconvenient for replacement when damaged. Furthermore, current plug inner frames do not have a wire-holding function. As a result, when the wire is pulled, it is easy for the wire to pull the plug out of the plug inner frame, which affects the plug's securing effect.

[0004] The existing patent (publication number: CN216563648U) relates to the field of environmental science and technology, specifically to a plug inner frame that facilitates wire securing. It includes a plug and a support outside the plug. The support has two symmetrical inserts at its top. The plug is inserted into the inserts. A locking rod is provided on the outer wall of the insert. An end plate is provided on the outer wall of the locking rod near its end. An electric wire is connected to the end of the plug. The end of the electric wire away from the plug is wrapped around the outer wall of the locking rod and extends out of the support. This utility model reduces the pulling force between the end of the electric wire and the end of the plug, preventing the plug from being pulled out of the insert, improving the installation and securing effect, and ensuring safety.

[0005] To address the aforementioned issues, existing patents offer solutions by wrapping the wire around the clamp and securing it with an end plate. However, under prolonged use or when subjected to external pulling, the spring force alone may not be sufficient to ensure the wire remains firmly attached to the clamp. With frequent plugging and unplugging or accidental pulling, the wire may loosen from the clamp, resulting in insufficient securing. Furthermore, the connection between the wire and the plug lacks an anti-detachment structure, making it prone to separation from the plug over time, leading to poor contact between the wire and the plug.

[0006] Therefore, a plug inner frame that facilitates cable clamping is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a plug inner frame that facilitates wire securing. This solves the problem that existing methods, which involve wrapping the wire around a clamp and fixing it with an end plate, may not be able to ensure that the wire is always firmly fixed to the clamp under long-term use or when subjected to external force. In the case of frequent plugging and unplugging or accidental pulling of the wire, the wire may loosen from the clamp, resulting in insufficient fixation of the wire. Furthermore, the lack of an anti-detachment structure at the connection between the wire and the plug makes it easy for the wire to detach from the plug after long-term use, leading to poor contact between the wire and the plug.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a plug inner frame for easy wire clamping, comprising a frame body, a wire sleeve provided on the rear side of the inner cavity of the frame body, a wire clamping assembly for use with the wire sleeve fixedly connected to the rear side of the inner cavity of the frame body, plug pieces provided on both sides of the front side of the inner cavity of the frame body, a wire core provided inside the wire sleeve, two wire cores respectively wound around the surfaces of two plug pieces, and anti-detachment assemblies for use with the wire cores provided on both sides of the front side of the inner cavity of the frame body;

[0009] The cable clamping assembly includes a U-shaped block, with a handle on the top of each side of the U-shaped block. A threaded rod is fixedly connected to the opposite side of each handle. The side of the threaded rod away from the handle extends into the inner cavity of the U-shaped block. A fixed clamping block is rotatably connected to the side of the threaded rod away from the handle via a bearing. The bottom of the fixed clamping block is slidably connected to the bottom of the inner wall of the U-shaped block.

[0010] Preferably, the anti-detachment component includes an anti-detachment clamping block, and a spring is fixedly connected to the side of the anti-detachment clamping block away from the wire core, and the side of the spring near the inner wall of the frame is fixedly connected to the inner wall of the frame.

[0011] Preferably, a first rubber pad is fixedly connected to the side of the anti-detachment clamping block away from the spring, and the side of the first rubber pad close to the wire core is in close contact with the wire core.

[0012] Preferably, the front and rear sides of the anti-detachment clamping block are fixedly connected to limit blocks, the inner wall of the limit block is slidably connected to a limit rod, and the side of the limit rod near the inner wall of the frame is fixedly connected to the inner wall of the frame.

[0013] Preferably, the top of both sides of the U-shaped block is provided with threaded holes for use with threaded rods, and the surface of the threaded rod is connected to the inner wall of the threaded hole by threads.

[0014] Preferably, a second rubber pad is fixedly connected to the side of the fixing block away from the threaded rod, and the side of the second rubber pad near the wire sleeve is in close contact with the wire sleeve.

[0015] Preferably, a limiting groove is provided on the rear side of the top of the frame for use with the wire sleeve, and the surface of the wire sleeve is in contact with the inner wall of the limiting groove.

[0016] Preferably, the side of the plug prong closest to the inner wall of the frame is fixedly connected to the inner wall of the frame, a reinforcing base is fixedly connected to the top of the surface of the plug prong, and the bottom of the reinforcing base is fixedly connected to the bottom of the inner wall of the frame.

By setting up the anti-detachment component, this application can tighten and limit the wire core, which can prevent the wire core from falling off the plug due to long-term impact and drop of the frame, thereby effectively improving the connection stability between the wire core and the plug.

[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. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A plug inner frame for easy cable clamping includes a frame body 1, a cable sleeve 2 provided on the rear side of the inner cavity of the frame body 1, a cable clamping assembly 3 for use with the cable sleeve 2 fixedly connected to the rear side of the inner cavity of the frame body 1, plug pieces 4 provided on both sides of the front side of the inner cavity of the frame body 1, a wire core 5 provided inside the cable sleeve 2, two wire cores 5 respectively wrapped around the surface of two plug pieces 4, and an anti-detachment assembly 6 for use with the wire core 5 provided on both sides of the front side of the inner cavity of the frame body 1.

[0029] The cable clamping assembly 3 includes a U-shaped block 301. A handle 302 is provided on the top of both sides of the U-shaped block 301. A threaded rod 303 is fixedly connected to the opposite side of the two handles 302. The side of the threaded rod 303 away from the handle 302 extends into the inner cavity of the U-shaped block 301. A fixed clamping block 304 is rotatably connected to the side of the surface of the threaded rod 303 away from the handle 302 through a bearing. The bottom of the fixed clamping block 304 is slidably connected to the bottom of the inner wall of the U-shaped block 301.

[0030] In this embodiment: by setting up a frame 1, a cable sleeve 2, a cable clamping assembly 3, a plug piece 4, a cable core 5, and an anti-detachment assembly 6, during use, the cable clamping assembly 3 can limit the position of the cable sleeve 2 and firmly clamp and fix the cable sleeve 2, so that the cable sleeve 2 will not move or fall off from the frame 1. Then, by winding and connecting the two cable cores 5 to the two plug pieces 4 respectively, the anti-detachment assembly 6 can tighten and limit the cable cores 5, which can prevent the cable cores 5 from falling off the plug pieces 4 due to long-term impact and drop of the frame 1, thereby effectively improving the connection stability of the cable cores 5 and the plug pieces 4.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, the anti-detachment component 6 includes an anti-detachment clamping block 601. A spring 602 is fixedly connected to the side of the anti-detachment clamping block 601 away from the wire core 5. The side of the spring 602 close to the inner wall of the frame 1 is fixedly connected to the inner wall of the frame 1.

[0032] Specifically, such as Figure 1 , Figure 3As shown, a first rubber pad 603 is fixedly connected to the side of the anti-detachment clamping block 601 away from the spring 602, and the side of the first rubber pad 603 close to the wire core 5 is in close contact with the wire core 5.

[0033] Specifically, such as Figure 1 , Figure 3 As shown, the front and rear sides of the anti-detachment clamping block 601 are fixedly connected to the limiting block 604, and the inner wall of the limiting block 604 is slidably connected to the limiting rod 605. The side of the limiting rod 605 near the inner wall of the frame 1 is fixedly connected to the inner wall of the frame 1.

[0034] In this embodiment: by setting an anti-detachment clamping block 601, a spring 602, a first rubber pad 603, a limiting block 604, and a limiting rod 605, during use, the force generated by the compression of the spring 602 will push the anti-detachment clamping block 601, so that the anti-detachment clamping block 601 can press against the wire core 5 through the first rubber pad 603, thereby effectively improving the connection stability between the wire core 5 and the plug piece 4. The setting of the limiting block 604 and the limiting rod 605 can prevent the anti-detachment clamping block 601 from shaking.

[0035] Specifically, such as Figure 2 As shown, threaded holes 7 are provided on the top of both sides of the U-shaped block 301 to cooperate with the threaded rod 303. The surface of the threaded rod 303 is connected to the inner wall of the threaded hole 7 by threads.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a second rubber pad 8 is fixedly connected to the side of the fixing block 304 away from the threaded rod 303, and the side of the second rubber pad 8 near the wire sleeve 2 is in close contact with the wire sleeve 2.

[0037] In this embodiment: by setting the threaded hole 7, the threaded rod 303 can be moved through the thread, and the position of the threaded rod 303 can be positioned by the thread. By setting the second rubber pad 8, the sleeve 2 can be protected, preventing the fixing block 304 from pinching the sleeve 2, and increasing the friction between the fixing block 304 and the sleeve 2, thereby improving the clamping effect of the sleeve 2.

[0038] Specifically, such as Figure 1 , Figure 4 As shown, a limiting groove 9 is provided on the rear side of the top of the frame 1 to cooperate with the wire sleeve 2, and the surface of the wire sleeve 2 is in contact with the inner wall of the limiting groove 9.

[0039] Specifically, such as Figure 1 , Figure 5 As shown, the side of the plug piece 4 closest to the inner wall of the frame 1 is fixedly connected to the inner wall of the frame 1, and a reinforcing base 10 is fixedly connected to the top of the surface of the plug piece 4, and the bottom of the reinforcing base 10 is fixedly connected to the bottom of the inner wall of the frame 1.

[0040] In this embodiment: by setting the limiting through groove 9, the position of the wire sleeve 2 can be limited; by setting the reinforcing seat 10, the plug piece 4 can be reinforced to prevent the plug piece 4 from separating from the frame 1.

[0041] Working principle: In use, the cable sleeve 2 is placed between two fixed blocks 304, and then the handle 302 is rotated, which drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 causes it to move under the action of the threaded hole 7. The threaded rod 303 drives the fixed blocks 304 to move, so that the two fixed blocks 304 can firmly lock and fix the cable sleeve 2, preventing the cable sleeve 2 from moving or falling off from the frame 1. Then, by winding and connecting the two wire cores 5 to the two plug pieces 4 respectively, the force generated by the compression of the spring 602 will push the anti-detachment clamping block 601, so that the anti-detachment clamping block 601 can press against the wire cores 5 through the first rubber pad 603. This can prevent the wire cores 5 from falling off the plug pieces 4 due to long-term impact and drop of the frame 1, thereby effectively improving the connection stability of the wire cores 5 and plug pieces 4.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
