Description

Technical Field

[0001] This utility model relates to the field of power transmission engineering technology, and in particular to a quick-connect device for power transmission engineering cables. Background Technology

[0002] During power transmission project construction, whether in the narrow alleys of urban power grid renovation, open-air work areas along highways, or high-voltage transmission line erection sites in remote mountainous areas, it is often necessary to connect copper or aluminum core cables of different specifications (such as 10mm², 25mm², etc.) to establish a complete power transmission link and achieve efficient transmission and rational distribution of power from substations to users. Currently, traditional cable connection methods mainly involve manually wrapping insulating tape or using terminal blocks; however, these methods have many problems.

[0003] Existing quick-connect devices for power transmission cables are cumbersome to install, require tools and are time-consuming, making them unsuitable for emergency repairs. They also have poor compatibility with different cable specifications, cannot flexibly adjust clamping force, and are prone to poor contact due to loose clamping or damage to cables due to excessive tightness. After connection, they lack reliable fixation and are easily loosened by external pulling. They also have insufficient insulation protection and pose a risk of leakage. Furthermore, splicing multiple devices is inconvenient and cannot meet the needs of long-distance cable connections. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems of low wiring efficiency, poor adaptability and unstable connection of existing devices, and to propose a quick-connect device for power transmission engineering cables.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-connect device for power transmission engineering cables, comprising a junction box, a wiring slot, and a quick-connect assembly. The junction box has a wiring slot in its middle. The quick-connect assembly is slidably connected to the upper and lower ends of the wiring slot. The quick-connect assembly includes pressing grooves at the upper and lower ends of the junction box. Compression springs are fixedly connected to the inner bottom walls of the four pressing grooves. Pressing blocks are fixedly connected to the tops of the compression springs. Three positioning slots are provided on each side of the pressing blocks. An arc-shaped conductive clip is fixedly connected to the bottom of the pressing blocks. Sliding cavities are provided on both sides of the inner walls of the four pressing grooves. Positioning slides are slidably connected to the inner walls of the sliding cavities. Positioning blocks are fixedly connected to one side of the eight positioning slides. The surface of the positioning blocks is engaged with the interior of the positioning slots. Limiting sliders are fixedly connected to one end of the eight positioning slides, and guide anti-slip handles are fixedly connected to the other end of the positioning slides.

[0006] Furthermore, the surfaces of the eight guide anti-slip handles are slidably connected to the junction box, and the inner sidewalls of the eight sliding cavities are provided with limiting grooves.

[0007] Furthermore, the surface of the limiting slider is slidably connected to the inner wall of the limiting groove, and magnetic plates are fixedly connected to the outer sides of the eight positioning sliders.

[0008] Furthermore, magnetic grooves are provided at both ends of the junction box, and the surface of the magnetic plate is attracted to the inner wall of the magnetic groove.

[0009] Furthermore, the inner side of the arc-shaped conductive clip is fixedly connected with an anti-slip protrusion, and the interlayer of the junction box wall is fixedly connected with an insulating filling layer.

[0010] Furthermore, the two ends of the wiring hole groove are fixedly connected to a tightening threaded arc member, and the surface of the tightening threaded arc member is connected to a retaining threaded hoop.

[0011] Furthermore, two latching strips are fixedly connected to one side of the junction box, and two latching slots are provided on the other side of the junction box. The surfaces of the two latching strips are latched to the latching slots of the other junction box.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a quick-connect component is provided. The pressing block of the quick-connect component is located in the pressing groove. After pressing, the compression spring contracts, causing the arc-shaped conductive clip to move down and clamp the cable. Wiring can be completed without additional tools, greatly improving operational efficiency and adapting to emergency repair scenarios. Multiple positioning slots on both sides of the pressing block, together with positioning blocks in the sliding cavity, allow the position of the pressing block to be adjusted according to the cable specifications, thereby changing the clamping force of the arc-shaped conductive clip and adapting to different cable specifications. This solves the problem of poor compatibility in existing devices. The positioning slider moves the positioning block, and the guide anti-slip handle facilitates operation. The limit slider slides along the limit groove to ensure that the positioning block accurately engages with the positioning slot, preventing the pressing block from slipping. The pressure block loosens, and the magnetic plate and magnetic groove adhere to each other, further fixing the positioning slide and enhancing connection stability. This prevents poor contact caused by external pulling. The anti-slip convex strip on the inner side of the arc-shaped conductive clamp increases friction with the cable, preventing cable slippage. The insulating filling layer of the junction box improves insulation performance and reduces the risk of leakage. The tightening thread arc of the wiring hole groove cooperates with the locking thread clamp to further fix the cable end and enhance connection reliability. The snap-fit ​​strip and snap-fit ​​groove engage, facilitating the splicing of multiple junction boxes and meeting the needs of long-distance cable connection. Overall, through convenient quick connection, flexible adaptation, stable fixation, and insulation protection, it meets the cable connection needs of power distribution projects, improving construction efficiency and electrical safety.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a quick-connect device for power transmission engineering cables, including a junction box 1, a wiring slot 2 and a quick-connect component 3. The junction box 1 has a wiring slot 2 in the middle, and the quick-connect component 3 is slidably connected to the upper and lower ends of the two ports of the wiring slot 2.

[0016] The following section will explain the specific settings and functions of its quick-connect component 3.

[0017] In this embodiment: the quick-connect assembly 3 includes pressing grooves 31 at the top and bottom ends of the junction box 1. Compression springs 32 are fixedly connected to the inner bottom walls of the four pressing grooves 31. Pressing blocks 33 are fixedly connected to the top of the compression springs 32. Three positioning slots 34 are opened on each side of the pressing blocks 33. An arc-shaped conductive clip 35 is fixedly connected to the bottom of the pressing blocks 33. Sliding cavities 36 are opened on both sides of the inner walls of the four pressing grooves 31. Positioning slides 37 are slidably connected to the inner walls of the sliding cavities 36. Positioning blocks 38 are fixedly connected to one side of the eight positioning slides 37. The surface of the positioning blocks 38 is engaged with the inside of the positioning slots 34. Limiting sliders 39 are fixedly connected to one end of the eight positioning slides 37. Guide anti-slip handles 310 are fixedly connected to the other end of the positioning slides 37.

[0018] The effects achieved by the above components are as follows: By setting the pressing groove 31 of the quick-connect component 3 to provide installation space for the compression spring 32 and the pressing block 33, pressing the pressing block 33 causes the compression spring 32 to contract, which drives the arc-shaped conductive clip 35 to move down and clamp the cable, so that wiring can be completed without additional tools, improving operation efficiency; the positioning slots 34 on both sides of the pressing block 33 cooperate with the positioning blocks 38 in the sliding cavity 36, so that the position of the pressing block 33 can be adjusted according to the cable specifications, and the clamping force of the arc-shaped conductive clip 35 can be changed to adapt to different specifications of cables; the positioning slide 37 drives the positioning block 38 to move, the guide anti-slip handle 310 facilitates the operation of the staff, and the limiting slider 39 limits the movement range of the positioning slide 37 to ensure that the positioning block 38 is accurately engaged in the positioning slot 34 and prevents the pressing block 33 from loosening.

[0019] Please see Figure 5 Specifically, the surfaces of the eight guide anti-slip handles 310 are slidably connected to the junction box 1, and the inner sidewalls of the eight sliding cavities 36 are provided with limiting grooves 4.

[0020] The effects achieved by the above components are as follows: by setting the guide anti-slip handle 310 to slide along the junction box 1, it ensures that the positioning slide 37 does not deviate when it moves, making it convenient for staff to apply force for adjustment; the limiting slide groove 4 on the inner side wall of the slide cavity 36 provides a sliding track for the limiting slider 39, further standardizing the movement path of the positioning slide 37 and preventing the positioning slide 37 from getting stuck or misaligned in the slide cavity 36.

[0021] Please see Figure 3-5 Specifically, the surface of the limiting slider 39 is slidably connected to the inner wall of the limiting groove 4, and magnetic plates 5 are fixedly connected to the outer sides of the eight positioning sliders 37.

[0022] The effects achieved by the above components are as follows: by setting the limit slider 39 to slide along the limit slide groove 4, the frictional resistance between the positioning slider 37 and the slide cavity 36 is reduced, making the positioning slider 37 move more smoothly; the magnetic plate 5 on the outside of the positioning slider 37 can be attracted to the corresponding structure of the junction box 1, providing additional fixing force for the positioning slider 37 and preventing the positioning slider 37 from moving in the non-operating state.

[0023] Please see Figure 4 Specifically, magnetic grooves 6 are provided at both ends of the junction box 1, and the surface of the magnetic plate 5 is attracted to the inner wall of the magnetic groove 6.

[0024] The effect achieved by the above components is as follows: by setting the magnetic groove 6 of the junction box 1 to attract the magnetic plate 5 of the positioning slide 37, the position of the positioning slide 37 is further fixed, ensuring that the positioning block 38 is stably engaged in the positioning slot 34, avoiding displacement of the positioning slide 37 due to external force vibration, and enhancing the stability of the arc-shaped conductive clamp 35.

[0025] Please see Figure 4-5Specifically, the inner side of the arc-shaped conductive clip 35 is fixedly connected with an anti-slip protrusion 7, and the box wall interlayer of the junction box 1 is fixedly connected with an insulating filling layer 8.

[0026] The effects achieved by the above components are as follows: by setting the anti-slip protrusions 7 on the inner side of the arc-shaped conductive clamp 35, the friction between the cable and the cable is increased, preventing the cable from sliding during clamping, ensuring stable contact between the cable and the arc-shaped conductive clamp 35, and avoiding poor contact; the insulating filling layer 8 of the junction box 1 wall interlayer improves the overall insulation performance of the device, isolates the external conductive environment, reduces the risk of leakage, and ensures construction and use safety.

[0027] Please see Figure 1-2 Specifically, the two ends of the wiring hole groove 2 are fixedly connected to a tightening threaded arc member 9, and the surface of the tightening threaded arc member 9 is connected to a retaining threaded clamp 10.

[0028] The effect achieved by the above components is as follows: by setting the tightening threaded arc 9 at the port of the wiring hole slot 2 and cooperating with the locking threaded clamp 10, tightening the locking threaded clamp 10 can cause the tightening threaded arc 9 to shrink, further fixing the end of the cable, preventing the cable from shaking in the junction box 1 or shifting when pulled by external force, and enhancing the reliability of the cable connection.

[0029] Please see Figure 1-2 Specifically, two clip strips 11 are fixedly connected to one side of junction box 1, and two clip grooves 12 are opened on the other side of junction box 1. The surfaces of the two clip strips 11 are clipped to the clip grooves 12 of the other junction box 1.

[0030] The effect achieved by the above components is that by setting the buckle strip 11 on one side of the junction box 1 to cooperate with the buckle groove 12 on the other side, multiple junction boxes 1 can be quickly spliced ​​together to meet the needs of long-distance cable connection or simultaneous connection of multiple groups of cables without the need for additional splicing components, thereby improving the flexibility of the device and construction efficiency.

[0031] Working principle: By setting up quick-connect component 3, the pressing block 33 of quick-connect component 3 is in the pressing groove 31. After pressing, the compression spring 32 contracts, which drives the arc-shaped conductive clamp 35 to move down and clamp the cable. The wiring can be completed without additional tools, which greatly improves the operation efficiency and is suitable for emergency repair scenarios. Multiple positioning slots 34 on both sides of the pressing block 33, together with the positioning block 38 in the sliding cavity 36, can adjust the position of the pressing block 33 according to the cable specification, thereby changing the clamping force of the arc-shaped conductive clamp 35, adapting to different specifications of cables and solving the problem of poor compatibility of existing devices. The positioning slide 37 drives the positioning block 38 to move, the guide anti-slip handle 310 facilitates operation, and the limit slider 39 slides along the limit slide groove 4 to ensure that the positioning block 38 is accurately engaged in the positioning slot. The groove 34 prevents the pressing block 33 from loosening. The magnetic plate 5 and the magnetic groove 6 are attracted to each other, further fixing the positioning slide 37, enhancing connection stability, and avoiding poor contact caused by external pulling. The anti-slip convex strip 7 on the inner side of the arc-shaped conductive clip 35 increases the friction with the cable and prevents the cable from sliding. The insulating filling layer 8 of the junction box 1 improves the insulation performance and reduces the risk of leakage. The tightening thread arc 9 of the wiring hole groove 2 cooperates with the locking thread clamp 10 to further fix the cable end and enhance the connection reliability. The buckle strip 11 and the buckle groove 12 engage to facilitate the splicing of multiple junction boxes 1 and meet the needs of long-distance cable connection. The whole system is convenient and quick to connect, flexible to adapt, stable to fix and insulated, suitable for the cable connection needs of power distribution projects, and improves construction efficiency and power safety.
