Description

Technical Field

[0001] This utility model relates to the field of electrical components technology, and in particular to a waterproof junction box. Background Technology

[0002] A junction box is a device used for connecting cables. When the cable laying length is long or when the cable needs to bend, a junction box is used to cover the part where two cables are connected, so as to protect the cables and connect them.

[0003] Existing junction boxes have few waterproof features, poor waterproof performance, and poor protection for connected cables.

[0004] To improve the waterproof performance and ease of installation of the junction box, existing junction boxes need to be improved. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing technologies, such as poor waterproofing and inconvenient installation, and provides a waterproof junction box with good waterproofing and convenient installation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a waterproof junction box, comprising:

[0007] The bottom of the outer casing is provided with a plurality of wiring cavities, and the periphery of the bottom of the outer casing and the wiring cavities is provided with pressure grooves;

[0008] The outer casing has an upper wiring cavity corresponding to the lower wiring cavity. A pressure strip is provided around the periphery of the outer casing and the lower wiring cavity. The pressure strip engages with a pressure groove. The lower wiring cavity and the upper wiring cavity constitute a wiring cavity. A waterproof connector for securing cables is installed inside the wiring cavity. A slot is provided on the top of the outer casing.

[0009] Side buckle, which is rotatably connected to the bottom of the outer shell and engages with the slot.

[0010] The junction box includes a base and a cover. Several lower wiring cavities are located on the base, in the center of the side wall. Grooves are provided around the base and the lower wiring cavities. The cover has several upper wiring cavities, and pressure strips are provided around the cover and the lower wiring cavities. The cover and base are joined to form the junction box; in this joined state, the pressure strips are inserted into the grooves for a snap-fit ​​connection. The upper and lower wiring cavities, when joined together, form a wiring chamber. A waterproof connector is installed inside the wiring chamber to secure the cables being wired inside the junction box. A slot is provided on the top of the cover, and a side latch is installed on the base. This side latch can rotate with the base, and its flipping action engages with the slot, ensuring stable and reliable assembly. The structure is a detachable assembly structure, which makes the assembly operation simple and convenient through the snap-fit ​​of the side buckles.

[0011] Preferably, a sealing foam strip is installed inside the pressure groove, and the sealing foam strip is in contact with the pressure strip. Specifically, the sealing foam strip, which is hollow and strip-shaped, is installed inside the pressure groove. When the outer cover and the outer cover are installed and connected, the pressure strip contacts the sealing foam strip, compressing it and improving the sealing effect. This results in a better waterproof seal after the outer cover and the outer cover are joined, thus improving their overall performance.

[0012] Preferably, a retaining block is provided at the port of the lower wiring cavity and the upper wiring cavity. The waterproof connector is U-shaped and has a wire-locking hole in the middle. A limiting block is provided on the side wall of the waterproof connector, and the retaining block corresponds to the limiting block. Specifically, retaining blocks are provided at the ports of the lower wiring cavity and the upper wiring cavity. The waterproof connector installed in the lower wiring cavity has a U-shaped structure, and a limiting block is provided on the side wall of the waterproof connector. This limiting block can cooperate with the retaining block to prevent the waterproof connector from sliding out of the lower wiring cavity, facilitating the assembly of the junction box, improving the convenience of assembly operations, and enhancing the performance.

[0013] Preferably, a silicone pillar is installed inside the junction box cavity. The silicone pillar is made of elastic material and has several compression grooves on its outer side. The silicone pillar also has a transition hole, which is coaxially arranged with the wire-clamping hole. The silicone pillar contacts the waterproof connector. The silicone pillar installed inside the junction box cavity contacts the end face of the waterproof connector installed inside the junction box. The compression grooves increase the compression deformation of the silicone pillar. This structure, through the elasticity of the silicone pillar, can compress the waterproof structure, reducing gaps in the connection and improving the sealing and waterproofing effect. A transition hole is provided in the middle of the silicone pillar, which is coaxially arranged with the wire-clamping hole in the middle of the waterproof connector. This structure facilitates the entry of cables from the waterproof connector and through the silicone pillar for connection in the middle of the bottom of the outer casing. This structure improves the waterproofing effect of the cable connection, thereby improving the usability of the junction box.

[0014] Preferably, the bottom sidewall of the outer casing is provided with a clearance groove, the clearance groove is provided with a shaft groove, the side buckle is a U-shaped structure, and the bottom of the side buckle is provided with a mounting shaft, which is rotatably connected to the shaft groove. Specifically, the clearance groove on the sidewall of the bottom of the outer casing has shaft grooves on both ends. Simultaneously, the side buckle structure is U-shaped, and mounting shafts are provided at both ends of the bottom of the side buckle. These mounting shafts are inserted into the shaft grooves for connection, allowing the side buckle to be rotatably mounted on the bottom of the outer casing. Furthermore, the bottom of the outer casing and the outer casing cover can be pressed and locked together by flipping the side buckle, making the installation operation convenient, simple, and highly reliable.

[0015] Preferably, the side latch has clearance notches in the middle and at the top. These clearance notches in the middle and at the top of the side latch allow for clearance of the connecting cable when the side latch is engaged, preventing interference and improving usability.

[0016] Preferably, the top inner surface of the side buckle is provided with a locking post, and the buckle groove is provided with a locking groove, wherein the locking post engages with the locking groove. Specifically, when the side buckle is closed and locked, the locking post on the top inner surface of the side buckle is embedded into the locking groove of the buckle groove, ensuring stable locking of the side buckle, improving the engagement effect, and thus enhancing the sealing performance and waterproofness of the waterproof box.

[0017] Preferably, a lever is provided on the top outer side of the side buckle, and the lever is arranged at an angle. The lever at the top of the side buckle, with its angled arrangement, facilitates the opening and closing of the side buckle and the slot, making installation easier and improving performance.

[0018] The advantages of this utility model are: strong waterproof reliability and good effect; and convenient and simple assembly and installation. Attached Figure Description
