Description

Technical Field

[0001] This utility model relates to the field of wire clip technology, specifically a wire clip for safe use. Background Technology

[0002] After the cable is laid, in order to make it a continuous line, the sections of the cable must be connected as a whole. These connection points need to be connected with clamps. The clamps are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration protection.

[0003] Chinese utility model patent application number 202120547503.6 provides a self-locking splicing clamp. It uses the pressure generated by the clamp cover closing to squeeze the cable. The clamping force and friction of the clamp are used to fix the position of the cable and connect the two wires at the terminal to achieve cable conduction. After the two clamp covers are assembled, the sealing is good and the moisture-proof layer can absorb the moisture that enters, thereby adjusting the safety of the clamp.

[0004] However, during the use of the above equipment, it was found that the cable itself has a certain weight. Especially when the cable is laid vertically or at an angle, the cable's own weight will generate additional tension under vibration or external impact. Relying solely on the friction of the sleeve to resist this tension can easily lead to insufficient fixation, causing the cable to slip down or the connection to loosen, affecting the cable's conductivity, and may even cause the connection to be interrupted, affecting the normal operation of the equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a safe and easy-to-use cable clamp, which solves the problem mentioned in the background art that relies solely on the friction of the clamp to resist the pulling force, which can easily lead to insufficient fixation, causing the cable to slip down or the connection to loosen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe and usable wire clamp, comprising an upper cover and a lower cover, each having a wiring groove in the middle, and wire grooves at both ends of the upper and lower covers. A wiring block is installed in the wiring groove of the lower cover, and a clamping assembly is provided in the wiring groove. The clamping assembly includes a rotating frame, a connecting rod rotatably connected to the rotating frame, a clamping block installed at one end of the connecting rod, a clamping groove on the clamping block, an array of anti-slip pads arranged in the clamping groove, and a spring connected to the bottom of the clamping block, the clamping block being connected to the bottom of the wiring groove via the spring.

[0007] Preferably, both the upper and lower covers have two sets of clamping components in their wiring slots, and the two sets of clamping components in a single wiring slot are symmetrical to each other.

[0008] Preferably, the rotating frame in the clamping assembly is located near the outer end of the wiring groove, and the clamping block is located near the middle of the wiring groove.

[0009] Preferably, a sealing gasket is installed on the inner wall at both ends of the wiring groove, and the sealing gasket has a groove corresponding to the wire groove, the diameter of the groove being smaller than that of the wire groove.

[0010] Preferably, both sides of the upper cover and the lower cover are provided with grooves, and one side of each groove is provided with a protrusion. The grooves and protrusions on both sides of the upper cover correspond to and are adapted to the protrusions and grooves on both sides of the lower cover.

[0011] This utility model provides a safe and reliable cable clamp. It has the following advantages:

[0012] (1) By setting up a clamping component, the present invention uses the clamping component to assist the wire groove to clamp and fix the cable, further restricting the degree of freedom of the cable, preventing it from shifting, shaking or falling off when subjected to external force, improving the stability of the cable fixation, ensuring that the cable always maintains the correct position during the operation of the equipment, and ensuring the reliability of the electrical connection.

[0013] (2) By setting the protrusion and groove to match, the present invention can achieve a tight connection between the upper cover and the lower cover, effectively preventing external moisture from entering the wiring groove from the joint between the two, and at the same time effectively preventing relative displacement or loosening between the upper cover and the lower cover, ensuring that the two always maintain a tight connection and maintain a good sealing effect.

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-4 A safe wire clamp includes an upper cover 1 and a lower cover 2. A wiring groove 8 is provided in the middle of the upper cover 1 and the lower cover 2. A wire groove 21 is provided at both ends of the upper cover 1 and the lower cover 2. A wiring block 3 is installed in the wiring groove 8 of the lower cover 2. A clamping assembly 7 is provided in the wiring groove 8. The clamping assembly 7 includes a rotating frame 71. A connecting rod 72 is rotatably connected to the rotating frame 71. A clamping block 73 is installed on one end of the connecting rod 72. A clamping groove 74 is provided on the clamping block 73. Anti-slip pads 75 are arranged in an array in the clamping groove 74. A spring 76 is connected to the bottom of the clamping block 73. The clamping block 73 is connected to the bottom of the wiring groove 8 through the spring 76.

[0021] Two sets of clamping components 7 are provided in the wiring grooves 8 of both the upper cover 1 and the lower cover 2, and the two sets of clamping components 7 in a single wiring groove 8 are symmetrical to each other.

[0022] The rotating frame 71 in the clamping assembly 7 is located near the outer end of the wiring groove 8, and the clamping block 73 is located near the middle of the wiring groove 8.

[0023] Specifically, when the cable is connected, the two cable segments are installed in the wire grooves 21 at both ends of the lower cover 2, and the two cable segments are connected by the connector block 3. When the cable is fixed, the two cable segments are placed in the clamping grooves 74 at both ends of the connector groove 8. When the upper cover 1 and the lower cover 2 are connected, as the upper cover 1 gradually moves closer to the lower cover 2, the clamping components 7 in the upper cover 1 and the lower cover 2 will also move closer to each other. When the upper cover 1 and the lower cover 2 are completely closed, the cable is clamped by the two clamping blocks 73 corresponding to the upper cover 1 and the lower cover 2. At this time, the spring 76 is compressed, generating a greater elastic force, which makes the clamping block 73 tightly clamp the cable, ensuring that the cable is firmly fixed in the clamping groove 74 in the connector groove 8. Since the clamping groove 74 is provided with an array of anti-slip pads 75, the anti-slip pads 75 are in close contact with the cable surface, which greatly improves the friction coefficient between the cable and the clamping block 73, making it difficult for the cable to slide axially in the clamping groove 74, further enhancing the ability to prevent the cable from axially separating.

[0024] The anti-slip pad 75 is made of rubber and its main function is to increase the friction between the clamping block 73 and the cable. The texture of its surface can form a better gripping effect with the cable sheath. At the same time, its soft and elastic material can act as a buffer, reducing the hard friction between the cable sheath and the clamping block 73. This prevents the cable sheath from being worn due to friction caused by vibration and other factors during the clamping process, which would affect the insulation performance and service life of the cable.

[0025] When the cable tends to detach axially from the outer end, the clamping blocks 73 on both sides will clamp the cable in the middle by rotating around the rotating frame 71 through the connecting rod 72 under the action of friction between the anti-slip pad 75 and the cable. This further restricts the axial movement of the cable, greatly enhances the effect of preventing the cable from detaching, and improves the stability of the cable fixation. This ensures that the cable always maintains the correct position during equipment operation and guarantees the reliability of the electrical connection.

[0026] To prevent moisture from entering the wiring duct 8, please refer to [link / reference needed]. Figures 1-4 Based on embodiment 1, sealing gaskets 4 are installed on the inner walls of both ends of the wiring groove 8. The sealing gaskets 4 have slots 41, which correspond to the wire groove 21. The diameter of the slots 41 is smaller than that of the wire groove 21.

[0027] Both sides of the upper cover 1 and the lower cover 2 are provided with grooves 5, and one side of each groove 5 is provided with a protrusion 6. The grooves 5 and protrusions 6 on both sides of the upper cover 1 correspond to and fit the protrusions 6 and grooves 5 on both sides of the lower cover 2.

[0028] Specifically, the sealing gaskets 4 installed on the inner walls of both ends of the wiring trough 8 can directly cover the connection between the wiring trough 8 and the wire trough 21, forming a physical barrier. When the upper cover 1 and the lower cover 2 are connected, they effectively prevent external moisture from entering the wiring trough 8 through the gap at the connection of the wire trough 21. The sealing gasket 4 itself has a certain degree of flexibility and elasticity, and the diameter of the groove 41 is smaller than that of the wire trough 21, so that when the upper cover 1 and the lower cover 2 are connected, the sealing gasket 4 can fit tightly against the surface of the cable, filling any possible tiny gaps and enhancing the sealing effect, thereby greatly reducing the possibility of moisture entering.

[0029] The grooves 5 and protrusions 6 on both sides of the upper cover 1 and the lower cover 2 correspond to and fit each other. When the upper cover 1 and the lower cover 2 are closed, the protrusions 6 can be accurately inserted into the grooves 5, forming a tight connection between the upper cover 1 and the lower cover 2. This tight fit can effectively prevent moisture from entering the wiring groove 8 from the joint, further improving the overall sealing performance. Since the grooves 5 and protrusions 6 are distributed on both sides of the upper cover 1 and the lower cover 2, they can prevent moisture from seeping into the wiring groove 8 from the side or edge, providing more comprehensive and reliable sealing protection for the inside of the wiring groove 8.

[0030] By effectively preventing moisture from entering the wiring trough 8, condensation on electrical components such as cable connectors and terminal blocks 3 can be prevented. The presence of moisture can degrade the insulation performance between electrical components, leading to safety hazards such as short circuits and leakage. Good sealing performance ensures that electrical components are always in a dry environment, maintaining their normal insulation performance, guaranteeing the reliability and safety of electrical connections, and extending the service life of electrical equipment.

[0031] Working principle: When connecting cables, the two cable segments enter through the wire grooves 21 at both ends of the lower cover 2 and are connected by the connector block 3. When fixing the cables, the two cable segments are placed in the clamping grooves 74 at both ends of the connector groove 8. Then, the upper cover 1 and the lower cover 2 are closed. As they approach each other, their respective clamping components 7 also approach each other. When fully closed, the two clamping blocks 73 corresponding to the upper cover 1 and the lower cover 2 clamp the cables. The spring 76 is compressed to generate greater elastic force, which makes the clamping blocks 73 clamp the cables and fix them firmly in the clamping grooves 74. The anti-slip pad 75 is in close contact with the cable sheath, which increases the coefficient of friction and prevents the cable from sliding axially. Its softness and elasticity can buffer the hard friction between the cable and the clamping blocks 73, avoiding wear on the sheath that affects the insulation and lifespan. If the cable tends to detach axially, the clamping blocks 73 on both sides rotate around the rotating frame 71 through the connecting rod 72 under the action of friction and clamp the cable in the middle, which enhances the anti-detachment effect and ensures the stability of the cable position and the reliability of the electrical connection.

[0032] When the upper cover 1 and the lower cover 2 are connected, the sealing gasket 4 forms a physical barrier at the connection between the wiring groove 8 and the wire groove 21. Its flexibility and elasticity allow it to fit tightly against the cable, fill the gap, and prevent moisture from entering the wiring groove 8 from the gap at the connection of the wire groove 21. At the same time, when the upper cover 1 and the lower cover 2 are closed, the protrusion 6 accurately inserts into the groove 5, and the two are tightly connected to prevent moisture from entering from the joint. Moreover, the groove 5 and the protrusion 6 are distributed on both sides, which can prevent moisture from seeping in from the side or edge, thus providing comprehensive and reliable protection for the inside of the wiring groove 8, ensuring that electrical components are dry, maintaining insulation performance, ensuring reliable and safe electrical connections, and extending the equipment life.
