Abstract
The utility model relates to a waterproof junction box. The waterproof junction box comprises an upper box cover, a lower box cover and waterproof rubber mats. Inner side walls of two opposite sides of the lower box cover are provided with embedded grooves with upward openings, groove walls of the embedded grooves and side walls of the lower box cover are provided with U-shaped grooves, side walls of the upper box cover are provided with n-shaped grooves, and the dimensions of heights of the n-shaped grooves are greater than dimensions of distances between the groove bottom of the U-shaped grooves and the bottom of the lower box cover. After the upper box cover covers on the lower box cover, groove bottom overlapped parts of the n-shaped grooves and the U-shaped grooves form cable holes, the waterproof rubber mats are embedded in the embedded grooves, the waterproof mats are provided with waterproof through holes at positions relative to the cable hole, the diameter of each waterproof through hole is not greater than that of each cable, and an elastic knife line mouth for the corresponding line to be transversely and elastically squeezed into the corresponding waterproof through hole is cut on each waterproof through hole. The U-shaped grooves, the embedded grooves, the n-shaped grooves and the waterproof rubber mats cooperate to form a line input port and a line output port; the U-shaped grooves and the embedded grooves are disposed at the two sides of the upper box cover; and the n-shaped grooves are disposed at the two sides of two sides of the upper box cover. The waterproof rubber mats can prevent rainwater from flowing into the junction box, and safety of wiring is improved.
Description
Technical field
The utility model relates to light fixture or power engineering termination field, especially a kind of outdoor lamp waterproof junction box.
Background technology
When outdoor lamp is installed or electric wire lays, often need to plug into electric wire or cable, the common mode of connection, most of interfaces are in the mode around adhesive plaster or encapsulating, and the former socket is all outside being exposed to, poor sealing, and rainwater or other electric conductors easily enter.Latter process is loaded down with trivial details, cost is too high, be used in especially outdoor products and above motor vehicle, have very large hidden danger, at secure context, can not guarantee, easily cause a series of potential safety hazards such as electric leakage, short circuit, cause unnecessary loss, application especially out of doors, a lot of hidden danger all can correspondingly occur, to operation, brought very large inconvenience, and useful life is shorter.
Summary of the invention
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of reasonable in design is provided, safe and reliable, the waterproof junction box of good airproof performance, and make wiring operation become more simple and convenient.
Technical solutions of the utility model are achieved in that
A kind of waterproof junction box, comprise lower casing, upper box cover and waterproof pad, the madial wall of the relative both sides of described lower casing is provided with for holding the caulking groove of waterproof pad, caulking groove opening up, on caulking groove cell wall and the sidewall of the lower casing corresponding with caulking groove be provided with U-lag, the sidewall that upper box cover is corresponding is provided with downward opening n shape groove, the height dimension of the n shape groove of upper box cover is greater than the bottom land of U-lag to the distance from bottom size of lower casing, after described upper box cover covers on lower casing, also opening is towards the opposite on same vertical line for n shape groove and U-lag, the bottom land lap of n shape groove and U-lag forms a cable hole of passing for cable, described waterproof pad is embedded in caulking groove, the corresponding cable hole of waterproof pad position is provided with waterproof through hole, waterproof through-hole diameter is not more than cable diameter, on waterproof through hole, cut the elastic blade line mouth of getting into for the horizontal waist elasticity of cable for one,
After coordinating, the n shape groove that the U-lag that described lower casing both sides arrange respectively and caulking groove, upper box cover both sides arrange respectively and waterproof pad form circuit input port and circuit delivery outlet.
Further, in order to prevent that rainwater from infiltrating between lower casing and upper box cover, passes through sealant sealing between lower casing and upper box cover.
The utility model cable can elasticity be got into the elastic blade line mouth that waterproof pad is provided with and is entered into waterproof through hole, after upper box cover covers on lower casing, the bottom land lap of n shape groove and U-lag forms one can hold the cable hole that cable passes, waterproof pad can seal up wire inlet-outlet position, prevent that rainwater from flowing in terminal box, wiring operation is simple and convenient, has greatly improved the fail safe of wiring.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is the structural representation after the utility model combination.
Embodiment
As Fig. 1, shown in 2, the utility model is a kind of waterproof junction box, its structure comprises lower casing 1, upper box cover 2 and waterproof pad 3, the madial wall of lower casing 1 relative both sides is provided with for holding the caulking groove 12 of waterproof pad 3, caulking groove 12 opening up, on caulking groove 12 cell walls and the sidewall of the lower casing 1 corresponding with caulking groove 12 be provided with U-lag 11, the sidewall of upper box cover 2 correspondences is provided with downward opening n shape groove 21, the height dimension of the n shape groove 21 of upper box cover 2 is greater than the bottom land of U-lag 11 to the distance from bottom size of lower casing 1, after upper box cover 2 covers on lower casing 1, also opening is towards the opposite on same vertical line for n shape groove 21 and U-lag 11, the bottom land lap of n shape groove 21 and U-lag 11 forms a cable hole of passing for cable 4, waterproof pad 3 is embedded in caulking groove 12, the corresponding cable hole of waterproof pad 34 positions are provided with waterproof through hole 31, waterproof through hole 31 diameters are not more than cable diameter, can be slightly less than cable diameter, elastic packing is better like this, on waterproof through hole 31, cut the elastic blade line mouth 32 of getting into for the horizontal waist elasticity of cable for one, after coordinating, the n shape groove 21 that the U-lag 11 that lower casing 1 both sides arrange respectively and caulking groove 12, upper box cover 2 both sides arrange respectively and waterproof pad 3 form circuit input port and circuit delivery outlet.Between lower casing 1 and upper box cover 2, pass through sealant sealing.Lower casing 1 and upper box cover 2 are screwed or weld sealing.
