Description

Technical Field

[0001] The present invention relates to the technical field of electrical wiring, in particular to an electrical safety wiring device. Background Art

[0002] The existing referenceable electrical junction box with the grant announcement number CN108631238B includes a box body and a box cover, the upper end surface of the box body and the two sides along the width direction of the box body are provided with a groove that is wide at the top and narrow at the bottom, the longitudinal section of the groove is a right-angled trapezoid, and the side close to the center of the box body is a right-angled surface, the side away from the center of the box body is an inclined surface, and the inclined surface is at an angle of 100-140 degrees to the bottom surface of the groove; the lower end surface of the box cover is provided with a convex strip that is interference-fitted with the groove on the box body, the bottom surface of the groove is provided with a threaded hole connected to the box cover by a bolt, and the front end surface of the box body is provided with a groove extending along the length direction of the groove and located in the groove. The water receiving groove just below the groove has a plurality of evenly arranged water holes connected to the water receiving groove on the bottom surface of the groove, and the bottom surface of the water receiving groove is a slanted surface with a higher inner side and a lower outer side. After the box cover is closed with the box body, if rainwater penetrates into the gap between the box cover and the box body, it will flow along the inclined surface into the bottom surface of the groove and cannot continue to flow into the inside of the box body. It flows through the water holes on the bottom surface of the groove into the water receiving groove below the groove, and then flows towards the water outlet of the water receiving groove and finally enters the water receiving box, effectively preventing rainwater from penetrating into the inside of the box body from the connecting gap between the box body and the box cover, so that the junction box achieves high-efficiency waterproof performance.
