[0002] Cable clamps are commonly used fixing connectors in power transmission and line connection. They are mainly used to fix cables and connect them to the wiring to ensure the stable laying and normal transmission of power lines.

[0003] However, traditional cable clamps have several drawbacks in practical use, affecting power transmission and wiring stability. Traditional cable clamps mostly use bolts for fixing, which can easily damage cables and thus affect power transmission performance. Especially when additional connections are needed in the middle of the cable, a T-shaped connection is usually used, which requires precise wire winding according to specifications, making the process cumbersome. Furthermore, traditional crimp-type clamps have few contact points at the crimping point, severely impacting power transmission quality and easily leading to cable loosening and poor contact at the connection point. Therefore, it is urgent to solve these problems. Summary of the Invention

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a cable fixing clamp with anti-loosening features, which has the following advantages: 1. This cable clamp with anti-loosening mechanism, through the design of a semi-circular slide rail, a semi-circular knob, and a hot melt adhesive strip, provides a double-seal anti-loosening effect. The staggered design of the semi-circular knob and the hot melt adhesive strip enhance the sealing of the connection between the lower and upper housings during use, preventing the clamp from loosening due to external forces. This enhances the overall connection stability of the clamp and prevents it from coming loose.

[0015] 2. This type of cable clamp with anti-loosening mechanism, through the setting of conductive and fastening modules, improves cable contact stability and prevents cable damage. The ring-shaped array of spiral wedge blocks and the coordinated tightening of the clamping plate and raised strips increase the contact area between the conductive blocks and the cable during use, achieving flexible clamping and fixing of the cable. This avoids damage to the cable sheath caused by direct bolt pressing, thereby improving power transmission quality and preventing poor contact.

[0016] 3. This cable clamp with anti-loosening feature simplifies cable wiring operations through the inclusion of a solder filling module and a self-heating module. The detachable solder storage tube, combined with the self-heating of thermite powder and the extrusion block for liquid solder, eliminates the need for external heating equipment and cumbersome winding operations, enabling rapid welding and fixing of cable connections. This improves cable wiring efficiency and simplifies T-shaped wiring operations.

[0017] 4. This type of cable clamp with anti-loosening feature, through the setting of ceramic insulating pad and protective shell, has the effect of improving insulation and protection performance. Through the insulating isolation of ceramic insulating pad and the sliding protection of the fastening module by the protective shell, it can effectively isolate the conductive contact between the cable and the shell during use, and at the same time prevent the fastening module from malfunctioning due to external impact and dust corrosion. Thus, it enhances the safety and durability of the clamp and achieves the purpose of improving the overall protection capability of the clamp. Attached Figure Description

Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0023] Please see Figures 1-3 The cable clamp with anti-loosening feature provided in this embodiment has an extension tube 2 on one side of the lower housing 1, which is arranged in a T-shape. The upper housing 20 is installed on the upper surface of the lower housing 1 and the extension tube 2 and is compatible with them. The lower housing 1 has semi-circular slide rails 3 at both ends, and semi-circular knobs 4 are rotatably connected to the inner side wall of the semi-circular slide rails 3. The upper housing 20 also has semi-circular knobs 4 at both ends. When the four semi-circular knobs 4 are fastened, the contact surfaces of the four semi-circular knobs 4 are misaligned with the contact surfaces of the lower housing 1 and the upper housing 20. Hot melt adhesive strips 5 are snapped onto the inner side wall of the semi-circular knobs 4. A knob 35 is threadedly connected to one end of the extension tube 2 and one end of the upper housing 20, forming a core structure with double sealing and anti-loosening features.

[0024] Specifically, during installation, the lower housing 1 and the upper housing 20 are fastened to the outside of the cable, ensuring that the four semi-circular knobs 4 are parallel to their respective housing contact surfaces. After fastening, the semi-circular knobs 4 are rotated 90° synchronously, utilizing their arc-shaped structure to form a circumferential lock. The knobs 35 at one end of the extension tube 2 and the upper housing 20 are tightened to complete the basic fastening of the housing. Subsequently, the heat generated by the self-heating module is transferred to the hot melt adhesive strip 5, which melts and bonds the semi-circular knobs 4, the lower housing 1, the upper housing 20, and the cable sheath together. The staggered semi-circular knobs 4 avoid the risk of loosening caused by overlapping connection surfaces, and the bonding of the hot melt adhesive strip 5 further enhances the sealing and anti-loosening effect, preventing the wire clamp from loosening due to external forces.

[0025] Please see Figures 4-7The lower housing 1 with anti-loosening cable clamp has a ceramic insulating pad 6 installed on its inner wall. A conductive module is movably installed on the inner wall of the ceramic insulating pad 6. The conductive module includes a conductive post 7, a terminal post 8, a conductive block 9, and silver contacts 36. The conductive post 7 is movably installed on the inner wall of the ceramic insulating pad 6. The terminal post 8 is fixedly connected to the upper surface of the conductive post 7. The conductive block 9 is integrally set with the conductive post 7 and movably installed on the inner wall of the lower housing 1. The silver contacts 36 are spirally arranged, with several evenly distributed in a ring array on the upper surface of the conductive block 9. A crimped cable connector 19 is detachably connected to the upper surface of the conductive post 7, located outside the terminal post 8, through a nut and the terminal post 8. The lower surface of the housing 1 is provided with a fastening module, which includes a wedge block 10, a pressure plate 11, a protruding strip 12, a groove 13, and a tightening bolt 14. The wedge block 10 is slidably connected to the inner bottom wall of the lower housing 1. The lower surface of the conductive block 9 is provided with an inclined surface that matches the wedge block 10. The pressure plate 11 is rotatably connected to the lower inner side wall of the lower housing 1 via a rotating shaft. The protruding strip 12 is fixedly installed on the left side of the upper surface of the pressure plate 11, and its outer surface abuts against the right side of the wedge block 10. The groove 13 is opened on the lower right side surface of the protruding strip 12. The upper end of the tightening bolt 14 passes through the groove 13 and is threadedly connected to the lower surface of the ceramic insulating pad 6, forming a key structure to improve contact stability and prevent cable damage.

[0026] Specifically, when fixing the cable, the end of the external cable is fixed to the terminal 8 by crimping the cable connector 19. The protective shell 15 is pushed to the right to release the clamp and rotated downward to open. Tighten the loosening bolt 14 to drive the clamping plate 11 to rotate around the pivot. The protruding strip 12 pushes the wedge block 10 to the left to slide along the inner bottom wall of the lower shell 1. The wedge block 10 lifts the conductive block 9 through the inclined surface. The spiral silver contacts 36 on the conductive block 9 are tightly attached to the gap of the cable bundle. The circular array of silver contacts 36 increases the contact area between the conductive block 9 and the cable, realizing flexible clamping and fixing, avoiding damage to the cable sheath caused by traditional bolt direct crimping. After clamping, the protective shell 15 is snapped upward and pushed to the left, so that the protruding block 16 is re-clamped with the inner wall of the protective shell 15, ensuring contact stability and improving the quality of power transmission.

[0027] Please see Figures 1-3 , Figures 8-11The upper housing 20 with anti-loosening cable clamps has a groove 21 on its upper surface, and a through groove 22 in the middle of the groove 21. A solder filling module and a self-heating module are detachably connected inside the groove 21. The solder filling module includes a solder storage tube 23, a spiral knob 25, an extrusion block 26, and a sealing film 28. The solder storage tube 23 is detachably connected to the inner wall of the groove 21 via a first slider 24 on its outer surface. The spiral knob 25 is threaded to the inner wall of the upper surface of the solder storage tube 23. The extrusion block 26 is slidably connected to the lower surface of the inner wall of the solder storage tube 23 in an arc shape that fits the inner cavity of the upper housing 20. The inner wall of the solder storage tube 23 is filled with liquid solder 27 mixed with flux. The sealing film 28 is adhered to the lower surface of the solder storage tube 23; the self-heating module includes a self-heating shell 29, a second slider 30, an opening 31, a mica sheet 32, and aluminothermic powder 33. The self-heating shell 29 is detachably connected to the inner wall of the slide groove 21 via the second slider 30. The opening 31 is opened on the lower right side of the self-heating shell 29, and the right side is adapted to the outer surface of the lower shell 1 and the upper shell 20. The mica sheet 32 ​​is adhered to the inner wall of the self-heating shell 29 and located inside the opening 31. The aluminothermic powder 33, which contains aluminum and copper oxide powder in a mass ratio of 3:2, is filled inside the self-heating shell 29. A raised top block 34 is installed on the left side of the lower shell 1 corresponding to the opening 31, forming a core structure that simplifies wiring operations.

[0028] Specifically, during wiring, there is no need for cumbersome wire winding. The solder storage tube 23 is inserted into the slide groove 21 via the first slider 24. The screw knob 25 is rotated to push the extrusion block 26 downward. Liquid solder 27 breaks through the sealing film 28 and flows into the inner cavity of the housing through the through groove 22, filling the contact gap between the cable and the conductive block 9 and the silver contact 36. Tighten the screw knob 25 to embed the extrusion block 26 into the through groove 22 to form a blockage. Slide the solder storage tube 23 to the left to remove it. Insert the self-heating outer shell 29 into the slide groove 21 via the second slider 30, so that its right side is tightly attached to the outer surface of the housing. During the installation process, the protruding top block 34 breaks through the mica sheet 32 ​​and squeezes the thermite powder 33, triggering the thermite reaction and releasing heat. The heat is transferred to the liquid solder 27 to melt it, welding the cable to the conductive block 9 and the silver contact 36 into one piece. No external heating equipment is required, and the wiring and fixing are completed quickly.

[0029] Please see Figures 4-6 The inner wall of the lower housing 1 with anti-loosening cable fixing clamp is equipped with a ceramic insulating pad 6, which wraps the conductive post 7, conductive block 9 and other components of the conductive module. A protective shell 15 is installed on the outside of the fastening module. A protrusion 16 and a limiting shaft 17 are fixedly connected to the lower surface of the lower housing 1. The inner wall of the right side of the protective shell 15 has a slot that matches the protrusion 16, and the inner wall has a limiting groove 18 that matches the limiting shaft 17. The end of the limiting shaft 17 is slidably connected to the inside of the limiting groove 18. The protective shell 15 can slide left and right and its upper surface is in close contact with the lower surface of the lower housing 1, forming a key structure for insulation protection.

[0030] Specifically, the ceramic insulating pad 6 isolates the conductive module from the lower housing 1 and the upper housing 20, effectively preventing the cable from making conductive contact with the housing, avoiding the risk of leakage, and improving safety. The fastening bolts 14, clamping plates 11, and other components of the fastening module are wrapped by the protective shell 15. The protective shell 15 maintains a tight fit with the lower housing 1 through the snap-fit ​​of the protrusion 16 and the guidance of the limiting shaft 17, preventing external collisions from causing the fastening module to loosen. At the same time, it blocks dust and moisture corrosion, avoids component failure, and enhances the durability of the clamp. When it is necessary to adjust the fastening state, the protective shell 15 can be opened simply by sliding it to the right, which is convenient to operate and combines protection and practicality.

[0031] In summary, when using the entire device: First, peel off the outer sheath of the cable to be connected to a length that matches the spacing between the two sets of hot melt adhesive strips 5. Initially snap the lower housing 1 onto the cable to be connected position. Then, pass the end of the external cable through the knob 35. Use a crimping device to crimp the cable connector 19 onto the end of the external cable. Secure it to the upper right surface of the conductive post 7 using the nut and the terminal block 8. Before snapping the lower housing 1 and the upper housing 20 together, ensure that the semi-circular knobs 4 on the lower housing 1 and the upper housing 20 are parallel to the corresponding mating surfaces of the housings. After the housings are fully snapped together, tighten the four semi-circular knobs... Knob 4 rotates 90° synchronously, using its arc structure to form a circumferential lock. Then, knob 35 is tightened at the end of extension tube 2 to complete the basic housing fastening. Subsequently, the protective shell 15 is pushed to the right to disengage it from the protrusion 16. The protective shell 15 is rotated downward around the limiting shaft 17 to open it. Tightening the loosening bolt 14 causes the pressure plate 11 to rotate around the rotating shaft. The protrusion 12 pushes the wedge block 10 to the left. The wedge block 10 slides along the inner bottom wall of the lower housing 1 and lifts the conductive block 9 through the inclined surface, so that the spiral silver contact 36 on the conductive block 9 is tightly attached to the gap of the cable harness, and the tightness is completed. After completion, snap the protective shell 15 upwards and push it to the left, so that the protrusion 16 re-engages with the inner wall of the protective shell 15; then, insert the solder storage tube 23 into the slide groove 21 through the first slider 24, rotate the screw knob 25 to push the extrusion block 26 downwards, and squeeze out the liquid solder 27 in the solder storage tube 23. After the liquid solder 27 breaks through the sealing film 28, it flows into the inner cavity of the shell through the through groove 22, filling the contact gap between the cable and the conductive block 9 and the silver contact 36. After the screw knob 25 is tightened in place, the extrusion block 26 is embedded in the through groove 22 to form a blockage, and then slide it to the left to remove the solder storage tube 23; Then, the self-heating outer shell 29 is inserted into the slide groove 21 through the second slider 30, so that its right side is tightly attached to the outer left side of the lower shell 1 and the upper shell 20. During the installation process, the protruding top block 34 breaks the mica sheet 32 ​​and squeezes the thermite powder 33, causing it to undergo an aluminothermic reaction and release heat. The heat is transferred through the shell to the cable connection position, causing the liquid solder 27 to melt and weld the cable to the conductive block 9 and the silver contact 36 into one piece. At the same time, the heat is transferred through the cable to melt the hot melt adhesive strip 5, bonding the semi-ring knob 4, the lower shell 1, the upper shell 20 and the cable sheath into one piece, achieving sealing and secondary anti-loosening.

[0032] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
