Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wiring terminals, and more specifically, it relates to a UKK junction box. Background Art
[0002] The working principle of a junction box is to connect the wires in a circuit to a box-shaped outer shell to protect and manage the circuit connections, improving the reliability and flexibility of the circuit. Its main principles include the following aspects:
[0003] 1. Wire connection: The junction box usually has multiple wire terminals for connecting the wires in the circuit. These wires can be fixed to the terminals by screws or clamping mechanisms to ensure the connectability of the wires.
[0004] 2. Insulation protection: The outer shell of the junction box is usually made of insulating materials, which can effectively prevent the leakage of current in the external environment or the occurrence of short circuits. This can protect the circuit from external interference and reduce the risk of electric shock.
[0005] 3. Managing circuit connections: The junction box makes it convenient to connect and disconnect various parts of the circuit by connecting the wires to the terminals. This can facilitate the replacement or repair of components in the circuit and reduce the impact on the entire circuit.
[0006] 4. Current distribution: The junction box can connect the wires from different power sources to the same terminal, thereby distributing the current to different branch circuits. This can control the flow direction and distribution of the current to meet the requirements of different circuits.
[0007] Existing junction boxes include an insulating housing, conductive connection blocks arranged in the insulating housing, and a cover plate for covering the conductive connection blocks. The cover plate is detachably connected to the insulating housing. A plurality of jacks for inserting the ends of the wires are provided on the conductive connection blocks, and a plurality of screws for fastening the wires are screwed on the conductive connection blocks. When the junction box leaves the factory, each screw is first screwed to the bottom. During use, the screws need to be withdrawn first to vacate the jacks for inserting the wires, which increases the operation steps and is not conducive to improving the convenience of using the junction box.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model, where the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0022] Refer to Figures 1-4As shown in the figure, a UKK junction box includes a box body 1 made of insulating material, a conductive connection block 2 arranged in the box body 1, and a cover plate 3 for covering the box body 1. The box body 1 insulates and wraps the conductive connection block 2 through the cover plate 3; the box body 1 includes a cavity 11 for the conductive connection block 2 to be embedded. The cover plate 3 is detachably connected to the opening of the cavity 11. The conductive connection block 2 is provided with an insertion hole 21 for the end of the wire to be inserted and a screw hole 22 communicated with the insertion hole 21. The insertion hole 21 and the screw hole 22 are arranged crosswise, preferably vertically. The box body 1 is provided with a through hole 12 corresponding to the insertion hole 21 to facilitate the wire to be inserted into the insertion hole 21 from outside the box body 1; between the conductive connection block 2 and the cover plate 3, there is an installation plate 4 for limiting the screw 5. The installation plate 4 is provided with a through hole 41 capable of accommodating the screw 5. The through hole 41 corresponds to the screw hole 22 so that the screw 5 in the through hole 41 can be screwed into the screw hole 22. The screw 5 screwed in the screw hole 22 can fasten the wire in the insertion hole 21.
[0023] In this application, the installation plate 4 is located between the conductive connection block 2 and the cover plate 3, and the through hole 41 on it can accommodate the screw 5. When assembling the junction box, the conductive connection block 2 can be first embedded into the cavity 11, then the installation plate 4 with the screw 5 can be installed into the cavity 11, and finally the cover plate 3 can be covered to complete the assembly of the junction box. When assembling the junction box, there is no need to screw the screw 5 into the screw hole 22. The screw 5 can be limited at the entrance of the screw hole 22 through the installation plate 4. Therefore, there is no need to screw the screw 5 into the screw hole 22 first, which is beneficial to improving the assembly efficiency of the junction box. Also, when using the finished junction box, there is no need to withdraw the screw 5 first. The end of the wire can be directly inserted into the insertion hole 21, and then the screw 5 can be screwed into the screw hole 22 until the wire is clamped and limited in the insertion hole 21, greatly improving the use convenience of the junction box.
[0024] The installation plate 4 is detachably connected to the opening of the cavity 11. A clamping groove 13 is provided on the inner wall of the cavity 11 near the opening. A clamping block 42 is protruded on the outer side wall of the installation plate 4 and can be clamped in the clamping groove 13. The installation plate 4 can be detachably connected to the box body 1, so that the installation plate 4 can be fixed in the cavity 11. Thus, even if the cover plate 3 is opened during the use of the junction box, the installation plate 4 will not fall off, and at the same time, the limiting stability of the screw 5 is further improved; in addition, the clamping groove 13 can penetrate through the wall thickness of the box body 1. One side of the clamping block 42 is provided with a wedge-shaped surface, which can facilitate the disassembly and assembly of the installation plate 4 and the box body 1.
[0025] In addition, there is no need for a connection structure between the conductive connection block 2 and the box body 1. The conductive connection block 2 can be limited in the box body 1 through the installation plate 4.
[0026] The inner diameter dimension of the perforation 41 is not less than the outer diameter dimension of the screw 5, and the inner diameter dimension of the end of the perforation 41 away from the conductive connection block 2 is less than the outer diameter dimension of the screw 5. The inner diameter dimension of the perforation 41 can be slightly larger than the outer diameter dimension of the screw 5, and the screw 5 is preferably a capless set screw with a consistent outer diameter, so that the screw 5 can be conveniently filled into the perforation 41; and the inner diameter dimension of the outer end of the perforation 41 is smaller, and the screw 5 can be effectively prevented from falling out of the perforation 41 after the mounting plate 4 is installed in place, effectively improving the convenience of use.
[0027] In addition, strip-shaped convex teeth can be convexly provided on the inner wall of the perforation 41. The convex teeth are arranged along the length direction of the perforation 41, and a plurality of convex teeth are provided. Each convex tooth is evenly distributed on the inner wall of the perforation 41, which is beneficial to avoid the screw 5 from shaking in the perforation 41, and is also beneficial to keep the screw 5 coaxial with the perforation 41 through the convex teeth, and further beneficial to the coaxiality of the screw 5 and the screw hole 22.
[0028] A convex ring 43 that can prevent touching the screw 5 is convexly provided on the outer side surface of the mounting plate 4 away from the conductive connection block 2 corresponding to the perforation 41. The convex ring 43 is preferably coaxial with the perforation 41 and convexly provided on the outer side surface of the mounting plate 4, which can effectively avoid touching the live screw 5, thus being beneficial to improving safety.
[0029] Locking ears 44 are convexly provided on the outer side surface of the mounting plate 4 away from the conductive connection block 2. Avoidance grooves 31 for the locking ears 44 to pass through are provided on the cover plate 3. Lock holes 441 are provided at the ends of the locking ears 44 passing through the avoidance grooves 31, and locking rods 32 corresponding to the locking ears 44 are provided on the cover plate 3. When the cover plate 3 covers the box body 1, the ends of the locking ears 44 can pass through the avoidance holes, and the locking rope can cooperate with the locking rods 32 to lock the cover plate 3 after passing through the lock holes 441.
[0030] A buckling block 33 is detachably connected to the outer side surface of the cover plate 3, and a writable writing surface is provided on the outer side surface of the buckling block 33. The buckling block 33 can be detachably connected to the cover plate 3 by a buckling method, which is convenient for disassembling and assembling the buckling block 33. At the same time, the setting of the writing surface enables the outer side surface of the buckling block 33 to be writable, which is convenient for recording the functions of the junction box and is beneficial to improving the flexibility of use of the junction box.
