Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, and in particular to a quick connection device for cable branch boxes. Background Technology

[0002] In power transmission systems, cable distribution boxes are crucial devices for cable splicing and branching. With the continuous growth of electricity demand, higher requirements are placed on the wiring efficiency and reliability of cable distribution boxes. Traditional cable distribution box wiring devices have several shortcomings, such as complex wiring operations that are time-consuming and affect construction progress; poor connection structure stability, easily leading to cable loosening due to vibration, external forces, etc., causing poor contact, overheating, or even malfunctions, affecting normal power transmission; and unreasonable structural design in some devices, making maintenance and repair inconvenient and increasing operation and maintenance costs and difficulty. Therefore, there is an urgent need for a fast wiring device for cable distribution boxes that enables rapid wiring, reliable connections, and is easy to operate and maintain. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0004] Design a quick-connection device for a cable branch box, including a box body, a circuit board fixedly installed on the rear wall of the box body, a branch cable connected to the circuit board, a support plate fixedly installed on the inner walls of both sides of the box body below the circuit board, a plurality of tapping components fixed on the upper surface of the support plate, and a crimping component provided above each tapping component.

[0005] The tap assembly includes a tap box fixed on a support plate and a conductor block embedded in the tap box. The crimping assembly includes a crimping protrusion crimped to the top of the tap box and a pressure plate connected to the top of each crimping protrusion. A lifting mechanism is provided on the top of the pressure plate.

[0006] Preferably, the lifting mechanism includes a threaded column rotatably connected to the middle position of the top of the pressure plate and a sleeve threadedly engaged with the threaded column, the top of the sleeve rotatably extending above the housing; guide rods are respectively provided at both ends of the pressure plate inside the housing.

[0007] Preferably, the sleeve is T-shaped, and the lower part of the sleeve is provided with an internal thread that engages with the threaded post, and the upper part of the sleeve is provided with a limiting block that is connected to the top of the threaded post. The limiting block is movably disposed in the upper part of the sleeve.

[0008] Preferably, arc-shaped grooves are provided at the upper and lower ends of the conductor block, the bottom of the pressing protrusion, and the bottom of the junction box, and anti-slip textures are provided on the inner wall of the arc-shaped grooves.

[0009] Preferably, a rotating ring is fixedly fitted onto the upper end of the sleeve, and anti-slip texture is provided on the outer wall of the rotating ring.

[0010] This invention uses a combination of a tap assembly and a crimping assembly. The crimping protrusion presses down to make the main cable and the conductor block make tight contact, thus achieving a reliable electrical connection between the main cable and the branch cable. The arc-shaped grooves of the conductor block, crimping protrusion, and tap box increase the contact area, reduce contact resistance and heat generation, and the anti-slip texture prevents the cable from sliding and avoids poor connection.

[0011] The lifting mechanism employs a threaded engagement between a threaded post and a sleeve. The lifting of the pressing protrusion is controlled by rotating the sleeve, simplifying operation. The upper rotating ring and anti-slip texture on the outer wall of the sleeve increase friction, facilitating force application and rotation, thus improving ease of operation and efficiency. The self-locking nature of the threaded drive ensures stable positioning after pressing; the guide rod ensures the pressing protrusion is pressed vertically and evenly; the T-shaped sleeve's internal limit block prevents the threaded post from disengaging, ensuring the lifting mechanism's safety and reliability. All components work together to ensure stable operation of the device.

[0012] The components within the device have clearly defined functions and a reasonable structural layout, enabling rapid identification and handling of problems during installation, maintenance, and repair, thereby reducing maintenance costs and difficulties. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0016] A quick-connection device for a cable branch box, such as Figure 1 As shown, the device includes a housing 1, a circuit board 5 fixedly installed on the rear wall inside the housing 1, a branch cable 8 connected to the circuit board 5, a support plate 3 fixedly installed on the inner walls of both sides of the housing 1 below the circuit board 5, a plurality of tapping components fixed on the upper surface of the support plate 3, and a crimping component provided above each tapping component.

[0017] The tap assembly includes a tap box 4 fixed on a support plate 3 and a conductor block 11 embedded in the tap box 4. The crimping assembly includes crimping protrusions 9 crimped to the top of each tap box 4 and a pressure plate 6 connected to the top of each crimping protrusion 9. A lifting mechanism is provided on the top of the pressure plate 6.

[0018] Branch cables 8 are connected via a circuit board 5 inside the housing 1, and a tap changer assembly is fixed using a support plate 3. A crimping assembly is positioned above the tap changer assembly. The tap changer assembly holds the main cable 10, and the crimping assembly is pressed down under external operation to ensure tight contact between the main cable 10 and the conductor block 11 inside the tap changer assembly, thus achieving an electrical connection between the main cable 10 and the branch cable 8. This structural layout is reasonable, and the tap changer assembly and crimping assembly work together to achieve a fast and reliable cable connection. The clear division of labor among the components facilitates installation, maintenance, and repair.

[0019] Furthermore, the lifting mechanism includes a threaded post 12 rotatably connected to the top center of the pressure plate 6, and a sleeve 13 threadedly engaged with the threaded post 12. The top of the sleeve 13 extends rotatably above the housing 1. Guide rods 7 are respectively installed at both ends of the pressure plate 6 inside the housing 1. The lifting mechanism utilizes the threaded engagement between the threaded post 12 and the sleeve 13. By rotating the sleeve 13, the threaded post 12 moves axially, driving the pressure plate 6 to rise and fall, thereby controlling the up-and-down movement of the pressing protrusion 9 to achieve pressing and release. The guide rods 7 limit the direction of movement of the pressure plate 6, ensuring its smooth lifting and lowering. The threaded drive has self-locking properties, ensuring positional stability after pressing; the guide rods 7 ensure that the pressing protrusion 9 is pressed vertically during the pressing process, making the pressing more uniform and reliable, and improving the connection quality.

[0020] Arc-shaped grooves are provided at the upper and lower ends of the conductor block 11, the bottom of the crimping protrusion 9, and the bottom of the junction box 4, with anti-slip textures on the inner walls of the arc-shaped grooves. The arc-shaped grooves on the conductor block 11, crimping protrusion 9, and junction box 4 better conform to the circular shape of the cable, increasing the contact area; the anti-slip textures on the inner walls increase friction, preventing the cable from sliding during crimping and use, ensuring the stability of the electrical connection. These structural features increase the contact area, reduce contact resistance, and decrease heat generation; preventing cable slippage avoids poor connections caused by loosening, improving the overall reliability of the device.

[0021] A rotating ring 14 is fixedly fitted onto the upper end of the sleeve 13, and anti-slip textures are provided on the outer wall of the rotating ring 14. The rotating ring 14 is fixed to the upper end of the sleeve 13, and the sleeve 13 is driven to rotate by manually rotating the rotating ring 14. The anti-slip textures on the outer wall of the rotating ring 14 increase the friction between the hand and the rotating ring 14, facilitating the application of force and operation. The anti-slip textures allow the operator to rotate the rotating ring 14 more easily and stably, improving operational convenience and efficiency, and reducing operational difficulty. Example 2

[0022] A quick-connection device for a cable branch box differs from Embodiment 1 in that the sleeve 13 is T-shaped, with an internal thread at the lower part of the sleeve 13 that engages with the threaded post 12, and a limiting block 15 at the upper part of the sleeve 13 that connects to the top of the threaded post 12. The limiting block 15 is movably positioned in the upper part of the sleeve 13. The T-shaped sleeve 13, with its lower internal thread engaging with the threaded post 12 for transmission, and the limiting block 15 at the upper part preventing the threaded post 12 from dislodging from the sleeve 13, limits the travel range of the threaded post 12 while ensuring its normal lifting and lowering. The limiting block 15 ensures the safety and reliability of the lifting mechanism, preventing the threaded post 12 from dislodging from the sleeve 13 and causing device malfunction; the T-shaped structure facilitates connection and operation with external rotating components.

[0023] The working process of this utility model is as follows: The main cable 10 is placed in the arc-shaped groove below the conductor block 11 inside the junction box 4, and at the same time, one end of the branch cable 8 connected to the circuit board 5 is placed in the arc-shaped groove above the conductor block 11, ensuring that the cable is placed in place. Then, the rotating ring 14 at the upper end of the sleeve 13 is rotated. Since the sleeve 13 is threadedly engaged with the threaded post 12, the rotation of the rotating ring 14 drives the sleeve 13 to rotate, and the threaded post 12 makes up-and-down linear motion inside the sleeve 13 (according to the principle of thread transmission, rotational motion is converted into linear motion). The threaded post 12 drives the pressure plate 6 to move downward, and the pressure plate 6 drives the pressing protrusion 9 to move downward. The pressing protrusion 9 gradually approaches and finally presses on the branch cable 8. The arc-shaped groove at the lower end of the crimping protrusion 9 fits tightly with the branch cable 8, thereby firmly pressing the main cable 10 and the branch cable 8 into the junction box 4. The anti-slip texture on the inner wall of the arc-shaped groove increases the contact pressure and friction, thereby achieving a stable and reliable electrical connection between the main cable 10 and the conductor block 11, and the branch cable 8 (which is electrically connected to the conductor block 11 through the circuit board 5), thus completing the quick wiring operation.

[0024] During disassembly, rotate the rotating ring 14 in the opposite direction to make the sleeve 13 rotate in the opposite direction. The threaded column 12 drives the pressure plate 6 to move upward, and the pressing protrusion 9 is lifted accordingly, relieving the pressure on the main cable 10 and the branch cable 8. The main cable 10 and the branch cable 8 can then be easily removed, completing the disassembly.

[0025] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
