Description

Technical Field

[0001] This utility model mainly relates to the technical field of electrical circuit connection, specifically a junction box that is easy to inspect and maintain. Background Technology

[0002] Junction boxes, as key components for wiring connections, are widely used in building, industrial, and civil electrical systems. Traditional junction boxes typically consist of a base and a cover, with internal wiring connections directly exposed inside the base, lacking effective protection and securing structures.

[0003] This design has the following drawbacks: 1. Difficult maintenance: The wire connectors are messy and disorganized, requiring each wire to be disassembled one by one during maintenance, which is inefficient and prone to accidentally touching other wires; 2. Poor contact: The wire connectors lack a fixed structure, and after long-term use, they are prone to loosening due to vibration or external force, leading to poor contact or even short circuits; 3. Insufficient protection: The connectors are directly exposed inside the box, making them susceptible to environmental factors such as dust and moisture, which reduces their service life and safety.

[0004] Although some junction boxes with protective structures have appeared in the existing technology, they are usually designed as a whole and cannot provide independent protection and quick maintenance for individual line connectors, thus failing to effectively solve the above problems. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a junction box that is easy to maintain, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A junction box that is easy to maintain includes a base box, wherein the bottom inner wall of the base box is provided with multiple connector protection boxes, and multiple wire holes are provided on the side walls at both ends of the base box; The connector protection box includes a base disposed on the inner wall of the bottom of the base box, a pressure cover hinged to one end of the base, a support block disposed on the top of the base, and a pressure block disposed on the bottom of the pressure cover.

[0007] Preferably, the top of the bottom box is hinged to a lid, and the lid is connected to one side of the bottom box by a fastener, which is connected by screws.

[0008] Preferably, the bottom of the base box is provided with connecting side plates on both sides, and the top of the connecting side plates is provided with at least one through hole.

[0009] Preferably, one end of the base is provided with a first through groove, and the other end of the base is provided with a second through groove.

[0010] Preferably, one end of the pressure cap is provided with a side block, and the side block is connected to one end of the base by screws.

[0011] Preferably, the top of the support block is made of pure copper and has an arc-shaped groove.

[0012] Preferably, the bottom of the pressure block is made of pure copper, and the two ends of the pressure block are also provided with side baffles, and the bottom of the pressure block is also provided with an arc-shaped groove.

[0013] In summary, this technical solution has the following main advantages: In this utility model, the modularly designed connector protection box enables independent protection and quick disassembly of individual line connectors, preventing accidental contact with other lines during maintenance. The hinged structure of the cover and base, combined with pure copper support blocks and pressure blocks, along with the arc-shaped wire groove design, ensures the secure fixing of the line connectors and prevents loosening.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figures 1 to 3 As shown, a junction box that is easy to maintain includes a bottom box 10, a plurality of connector protection boxes 20 are provided on the bottom inner wall of the bottom box 10, and a plurality of wire holes 11 are provided on the side walls at both ends of the bottom box 10. The connector protection box 20 includes a base 21 disposed on the inner wall of the bottom of the base box 10, a pressure cover 22 hinged to one end of the base 21, a support block 23 disposed on the top of the base 21, and a pressure block 24 disposed on the bottom of the pressure cover 22.

[0018] It should be noted that in this embodiment, the top of the bottom box 10 is hinged with a cover 12, and the cover 12 and the bottom box 10 are provided with a connecting buckle 121. The connecting buckle 121 is connected by screws. The cover 12 serves as a protective layer for the connector protection box 20 inside the bottom box 10 and is connected by screws, which makes it easy to disassemble and carry out construction when the connector needs to be repaired or replaced.

[0019] The bottom of the base box 10 is provided with connecting side plates 101 on both sides. At least one through hole 102 is provided on the top of the connecting side plate 101. Both the connecting side plate 101 and the through hole 102 are used to fix the base box 10 with screws, maintain the stability of the base box 10 and better play a protective role.

[0020] The base 21 has a first through groove 211 at one end, which is used to fit the wire hole 11 near its side to insert the wire end. The base 21 has a second through groove 212 at the other end, which is based on the same principle as the first through groove 211 and is used to fit the wire end near the wire hole 11 near its side to insert.

[0021] The pressure cap 22 has a side block 221 at one end, which is used to connect to one end of the base 21 by screws.

[0022] The top of the support block 23 is made of pure copper, and the bottom of the pressure block 24 is made of pure copper. This facilitates the application of force to protect the wire ends, while also improving flame retardancy and effectively preventing direct contact with plastic, which is flammable and could affect other undamaged connectors inside the junction box.

[0023] The top of the support block 23 has an arc-shaped wire groove 231, and the bottom of the pressure block 24 also has an arc-shaped wire groove 231, providing reserved space for the wire ends placed inside.

[0024] The pressure block 24 is also provided with side baffles 241 at both ends, which play a certain role in blocking the first through groove 211 and the second through groove 212, and help protect the internal wire ends from external interference.

[0025] The working principle of this utility model is as follows: In actual use, the bottom box 10 is fixed in a pre-prepared position by connecting the side plate 101 and the through hole 102 with screws. Then, one wire end is passed through the wire hole 11 and the first through groove 211 on one side in sequence. Based on the same operation, the other wire end is passed through the wire hole 11 and the second through groove 212 on one side in sequence. After the two wire ends are connected by winding, they are wrapped with protective insulating tape and placed on top of the support block 23. The pressure cover 22 is then covered and fixed to one end of the base 21 by screws through the side block 221. Finally, the box cover 12 is fixed.

[0026] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
