Rolling type waterproof junction box

Abstract

The invention discloses a rolling type waterproof junction box, which belongs to the field of junction boxs. According to the rolling type waterproof junction box, a transverse outer convex bag and a pressing ring are arranged outside a wiring pipe, and after wiring is completed, the transverse outer convex bag is rolled through the pressing ring, so that an attaching inner bag is attached to the surface of the wiring pipe; meanwhile, compressed air in the transverse outer convex bag intensively moves towards the expansion outer bag, so that the expansion outer bag expands transversely and outwards and wraps the outer end of the connector of the wire and the wiring pipe, the waterproof rubber ring is stressed and damaged due to the extrusion effect of the compressed air, glass cement in the waterproof rubber ring overflows, a glass cement layer is formed between the transverse outer convex bag and the electric wire, a gap between the wiring pipe and the electric wire is effectively blocked, and compared with the prior art, waterproof loopholes at the wiring pipe are effectively made up, so that potential safety hazards are reduced, and the service life of the junction box is prolonged.

Description

technical field [0001] The invention relates to the field of junction boxes, more specifically, to a rolling type waterproof junction box. Background technique [0002] In home decoration, the junction box is one of the electrical accessories, because the wires used for decoration pass through the wire tube, and the junction box is used as a transition at the joint of the wire (for example, the line is relatively long, or the wire tube needs to be cornered). Use, the wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box to protect the wires and connect the wires. This is the junction box. [0003] In the prior art, the junction box generally has a waterproof function, but its waterproof structure is generally arranged at the junction of the box body or the box cover and the box body, and is mainly used to protect the wiring terminals in the junction box from moisture, but the junction box is used for walking. The wiring...

Problems solved by technology

[0003] In the prior art, the junction box generally has a waterproof function, but its waterproof structure is generally arranged at the junction of the box body or the box cover and the box body, and is mainly used to protect the wiring terminals in the junction box from moisture, but the junction box is used for walking. The wiring tube of the wire is generally exposed outside. After wiring, when accidentally exposed to water, the water will easily seep into the box along the gap between the wire and the wiring tube, resulting in a certain loophole in the waterproof performance, which not only has a certain safety Hidden dangers, also lead to the service life of the junction box is affected
