Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to an outdoor waterproof junction box. Background Art

[0002] Junction boxes are devices used to connect, distribute and protect electrical circuits. They are usually used in electrical systems. Different types of junction boxes can be selected according to different uses and occasions, such as outdoor waterproof junction boxes, low-voltage junction boxes, high-voltage junction boxes, etc.

[0003] In the prior art, such as Chinese patent publication number: CN216851197U, discloses "an outdoor waterproof junction box", which includes a bottom cover and an upper cover, wherein insulating partitions are evenly fixedly installed on the lower end of the inner wall of the bottom cover, and conductive copper sheets are fixedly installed between the insulating partitions. A glue pouring hose is provided on the upper end of the upper cover to facilitate glue pouring, and mounting plates are fixedly installed on both sides of the upper end of the inner wall of the upper cover, and wire clamping grooves are evenly opened on the surface of the mounting plates.

[0004] However, in the prior art, during the use of the outdoor waterproof junction box, after the wires are connected to the junction box, glue is used for sealing and waterproofing, which can easily cause the bottom cover and the upper cover of the junction box to stick to each other, and at the same time cause the wires to stick to the junction box. When the junction box ages after long-term use in an outdoor environment and needs to be replaced, the sealing glue will cause the junction box to be unable to be opened smoothly, and the wires and the junction box are difficult to separate. At the same time, in some outdoor operations, when the junction box needs to be used for short-term connection and protection of the wires, the existing junction box cannot form effective waterproof protection for the wires without glue injection. Based on this, the utility model designs an outdoor waterproof junction box to solve the above problems. Utility Model Content
