Description

Technical Field

[0001] This utility model relates to the field of wiring protection technology, and in particular to electrical secondary wiring protection devices. Background Technology

[0002] In electrical systems, secondary wiring plays a crucial role in signal transmission and control command delivery. Its connection stability directly affects the safe operation of the entire system. As a core component to ensure reliable cable connections, the secondary wiring protection device works by fixing the cable in a preset position using a mechanical structure, using the constraint force of the clamping parts to counteract external forces, and limiting the displacement range of the cable through a limiting structure. This ensures that the connection between the cable and the terminal block always maintains stable contact, avoiding signal interruption or circuit failure due to position changes.

[0003] Existing secondary wiring protection devices mostly adopt simple clamping structures, such as metal clamps or plastic brackets, to fix cables by tightening bolts. These devices have obvious drawbacks: First, the clamping force is not adjustable, and it is easy to become too loose or too tight due to differences in cable diameter. Too loose will cause the cable to wobble and wear, while too tight may damage the wire core. Second, the limiting structure is simple, which can only limit the axial displacement of the cable and cannot prevent lateral movement. To solve the above problems, some existing technologies use elastic pads to increase friction or adjust the clamping range through multi-position buckles. However, these solutions still have shortcomings: elastic pads are prone to aging and failure under long-term stress, losing their buffering effect; multi-position adjustment structures are complex, cumbersome to operate, and have a limited range of applicability, making it difficult to meet the precise fixing requirements of cables of different specifications.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an electrical secondary wiring protection device, including a housing 1, a fixing mechanism 2 installed inside the housing 1, the fixing mechanism 2 is used to protect the cable and fix its position, and a wire stripping mechanism 3 is slidably connected to the middle of the top wall of the housing 1, the wire stripping mechanism 3 is used to peel the insulating rubber from the wire core.

[0032] The fixing mechanism 2 includes multiple adjusting bolts 201, which are threaded to the front and rear sides of the outer wall of the outer shell 1. The outer walls of the multiple adjusting bolts 201 are threaded to clamping plates 202, which are slidably connected to the front and rear sides of the inner wall of the outer shell 1. The bottom of the multiple clamping plates 202 is fixedly connected to sliders 203. The left and right sides of the inner bottom wall of the outer shell 1 are provided with slide rails 204. The front and rear sides of the inner wall of the outer shell 1 are fixedly connected to two limiting pieces 206. The multiple limiting pieces 206 are threaded to the outer walls of the adjusting bolts 201. A clamping assembly 205 is installed in the middle of the bottom wall of the outer shell 1.

[0033] The clamping assembly 205 includes a metal clamp 2051, which is rotatably connected to the middle of the bottom wall of the housing 1. A rotating pin 2052 is installed on the front side of the metal clamp 2051, which is rotatably connected to the front side of the middle of the bottom wall of the housing 1. Multiple anti-slip teeth 2053 are provided on the bottom of the metal clamp 2051.

[0034] Support piles 5 are fixedly connected to the four corners inside the clamping plate 202. The slider 203 is slidably connected to the inner wall of the slide rail 204. The clamping plate 202 is slidably connected to the outer shell 1 through the slider 203 and the slide rail 204.

[0035] Specifically, the outer casing 1 is composed of a lower shell and an upper cover. The edge of the upper cover is slidably connected to the top of the shell through sliding grooves on both sides. Two cables to be connected are inserted into the internal space of the outer casing 1 through corresponding holes on the left and right sides, respectively, so that the ends of the cables make initial contact at the position of the metal clip 2051. Then, the metal clip 2051 is flipped downward around the rotation axis of the metal clip 2051, and the arc of the clip locks the connecting parts of the two cables together. The rotating pin 2052 located on one side of the metal clip 2051 is rotated, and the horizontal bar set at the top of the rotating pin 2052 locks the position of the metal clip 2051. The anti-slip teeth 2053 on the inner side contact the cable surface to increase friction and prevent the cable from sliding when under force. Then, close the cover and rotate the adjusting bolt 201. The two ends of the limiting plate 206 are fixed to the inner wall of the outer shell 1 to limit the horizontal position of the adjusting bolt 201 on the outer shell 1. Therefore, when the adjusting bolt 201 rotates around its own axis, the clamping plate 202 connected to it by threads will move horizontally. The slider 203 at the bottom of the clamping plate 202 is embedded in the slide rail 204 at the bottom of the outer shell 1 to ensure the continuity of movement and the stability of direction. The clamping plates 202 on the left and right sides move towards each other under the action of the adjusting bolt 201, clamping the cable joint from both sides inward, increasing the lateral constraint and fixation of the cable.

[0036] Reference Figure 4 and Figure 5 The wire stripping mechanism 3 includes a mounting cylinder 301, which is slidably connected to the middle of the top wall of the outer casing 1. Two dovetail tenons 304 are fixedly connected to the bottom of the mounting cylinder 301. The mounting cylinder 301 is slidably connected to the top of the outer casing 1 through the dovetail tenons 304. Multiple cutting components 302 are equidistantly installed on the inner wall of the mounting cylinder 301. A stabilizing component 303 is fixedly connected to the front side of the inner wall of the mounting cylinder 301.

[0037] The cutting assembly 302 includes a tool holder 3021, which is fixedly connected to the middle of the inner wall of the mounting cylinder 301. An adjusting bolt 3023 is threaded to the middle of the tool holder 3021, and a cutting blade 3022 is installed in the middle of the tool holder 3021. The cutting blade 3022 is installed in the middle of the tool holder 3021 by the adjusting bolt 3023.

[0038] The stabilizing component 303 includes a connecting ring 3031, which is fixedly connected to the right side of the inner wall of the mounting cylinder 301. Multiple clamping blocks 3032 are equidistantly slidably connected to the inner wall of the connecting ring 3031, and springs 3033 are fixedly connected to the outer sides of the multiple clamping blocks 3032.

[0039] Multiple clamping blocks 3032 are fixedly connected to the right side of their outer walls with sliding strips 7, and the multiple clamping blocks 3032 are slidably connected to the inner wall of the connecting ring 3031 through the sliding strips 7;

[0040] Specifically, the cable whose insulation layer is to be stripped is horizontally inserted through the left opening of the mounting cylinder 301. Multiple clamping blocks 3032, evenly distributed within the connecting ring 3031 inside the mounting cylinder 301, move towards the center to create a centripetal force, clamping and fixing the outer surface of the cable in the longitudinal direction. This prevents the cable from bending or deflecting during stripping, which would affect the accuracy and effectiveness of the stripping process. The outer side of each clamping block 3032 is connected to one end of a spring 3033, the other end of which is fixed to the inner wall of the connecting ring 3031, applying continuous elastic force to the clamping blocks 3032. The opening size between the clamping blocks 3032 can be automatically adjusted according to the thickness of cables of different diameters. Simultaneously, the elastic force of the spring 3033 enhances the clamping force on the cable surface, ensuring a secure fixation. The cutting edge of the blade 3022... The blade 3022 cuts the insulation rubber of the cable in contact with it. The operator holds the end of the cable and pulls it to the right in the mounting cylinder 301. The blade 3022 cuts the insulation layer axially from the end of the cable until the insulation layer is completely peeled off. The blade 3022 is mounted on the inner wall of the mounting cylinder 301 through the blade holder 3021 at the bottom and is fixed to the mounting cylinder 301 by the adjusting bolt 3023 that passes through the blade holder 3021. The adjusting bolt 3023 is removed from the threaded hole, and the blade 3022 is moved longitudinally on the blade holder 3021 to change its position. The adjusting bolt 3023 is then locked through the blade holder 3021. The cutting position and cutting depth of the blade 3022 on the connecting ring 3031 can be adjusted according to the thickness of the cable.

[0041] Reference Figure 1 , Figure 3 and Figure 5 Guide holes 4 are fixedly connected to the bottom of the left and right sides of the outer wall of the outer shell 1, and two dovetail grooves 6 are opened on the top wall of the outer shell 1.

[0042] Specifically, the guide hole 4 is flared to guide the inserted cable and prevent the cable from being damaged by severe friction between the cable and the outer casing 1. The dovetail groove 6 provides the dovetail tenon 304, which is distributed axially in the front and back to prevent the mounting cylinder 301 from sliding left and right during operation.

[0043] Working principle: The outer casing 1 consists of a shell and a top cover. The top cover is connected to the shell by sliding. The cables to be connected are inserted into the outer casing 1 through the holes on the left and right sides. Initial connection is completed at the metal clip 2051. Then, the metal clip 2051 is flipped down to fasten and fix the two cables. Rotating the rotating pin 2052 locks the metal clip 2051 onto the outer casing 1 through the crossbar at the top of the rotating pin 2052. The anti-slip teeth 2053 increase friction and prevent the cables from slipping. After closing the top cover, rotating the adjusting bolt 201 fixes the adjusting bolt 201 onto the outer casing 1 with the limiting piece 206. The cable is positioned horizontally, so when the adjusting bolt 201 rotates, the clamping plate 202 will move horizontally accordingly. The slider 203 and the slide rail 204 ensure the continuity of movement and the stability of direction. The clamping plates 202 on both sides move towards each other, clamping the cable inward and increasing the lateral constraint. This mechanism can fix the cable in both the lateral and longitudinal positions without the need for elastic pads and other complex mechanisms. It solves the problems of existing technologies where elastic pads are prone to aging and failure under long-term stress, losing their buffering effect; multi-position adjustment structures are complex, cumbersome to operate, and have limited adaptability, making it difficult to meet the precise fixing requirements of cables of different specifications.

[0044] The cable to be stripped is inserted into the left side of the mounting cylinder 301. Multiple clamps 3032 in the connecting ring 3031 create a centripetal force, fixing the cable longitudinally and preventing cable distortion from affecting the stripping effect. A spring 3033 applies elastic force to the clamps 3032, allowing adjustment of the opening size according to the cable thickness. Simultaneously, the spring force of the spring 3033 increases the clamping force. The blade 3022 cuts the cable's insulation rubber. The operator pulls the cable within the mounting cylinder 301, and the blade 3022 cuts from the end... Begin cutting until all wires are stripped. Blade 3022 is mounted on mounting cylinder 301 via blade holder 3021 and secured by adjusting bolt 3023. Remove adjusting bolt 3023, move blade 3022 longitudinally on blade holder 3021, and then lock it with adjusting bolt 3023. The cutting position and depth of connecting ring 3031 can be adjusted according to the thickness of the cable. This mechanism allows the operator to complete wire stripping without direct contact with the blade, preventing accidental injury and ensuring operational safety.

[0045] 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.
