Description

Technical Field

[0001] The invention belongs to the technical field of junction boxes, and in particular relates to a junction box for an outdoor power system. Background Art

[0002] Street lamps are widely used in modern life. When installing street lamps, the lamp poles are hoisted onto the pre-buried flanges, bolted and then fixed with cement. The cable is connected from the middle of the flange to the junction box through the inside of the lamp pole, and the cable connected to the light source on the lamp stand is connected to the junction box through the inside of the lamp pole. When manufacturing street lamps, due to cost and line requirements, hollow lamp poles are generally used. In order to ensure the strength of the lamp pole, the hole opened on the side wall of the lamp pole for placing the junction box is usually small. This phenomenon is more obvious when the lamp pole is longer. As a result, when subsequent staff connect the wires, they need to open the outer end protective cover of the junction box on the lamp pole first, hold a small tool to operate the junction box through the small hole opened on the lamp pole, or pull the cables connected to the junction box from the upper and lower parts of the lamp pole to the outside of the lamp pole, and then plug it back into the lamp pole and fix the junction box again. This is very inconvenient; this problem will also continue to the later circuit maintenance, reducing work efficiency.

[0003] In Chinese patent literature, there is a patent document with publication number CN 215119991 U, entitled "Portable Junction Box for Outdoor Street Lights". The utility model provides a portable junction box for outdoor street lights, including: a lamp pole, which is hollow and has a placement hole connecting the inside and the outside; a bearing mechanism, which is installed in the lamp pole and used to bear the junction box; a blocking mechanism, which is installed in the lamp pole and used to block the placement hole; a driving mechanism, which is installed in the lamp pole and is respectively connected to the bearing mechanism and the blocking mechanism; wherein the driving mechanism drives the blocking mechanism to release the blocking of the placement hole and drives part of the bearing mechanism to extend from the placement hole. In the technology of the utility model, the driving mechanism drives the blocking mechanism and the bearing mechanism at the same time to realize the contact blocking of the blocking mechanism at the placement hole, and the operation of the junction box extending from the placement hole is realized. The staff can operate the junction box on the extended bearing mechanism, and after completion, the device is reversed, and the junction box returns to the lamp pole, which greatly improves the convenience and efficiency.

[0004] However, the junction box in the above patent document has a complex structure and high cost. The junction box itself has low strength, poor heat protection and ventilation, and its safety cannot be guaranteed. This is a technical problem that we urgently need to solve.

[0025] Combination Figure 1-Figure 3, is a schematic diagram of the principle structure of an embodiment of a junction box for an outdoor power system of the present invention, the junction box for an outdoor power system comprises a body 1, the body 1 is formed by bending a plate to form a rear plate 7 with upper and lower end surfaces in a U shape and a three-sided connection body of left and right plates, the rear plate 7 is provided with a mounting hole 12, and the rear plate 7 is fixed to a vertical or horizontal fixed body by screws, the upper and lower end surfaces of the body 1 are connected with upper and lower plates 3, in order to facilitate the folding during production and ventilation during use, the upper and lower plates 3 are provided with a notch 8 near the rear side and the corner of the body 1, the U-shaped mouth body 1 is provided with vertical folding edges 10 on both sides, the middle of the folding edge 10 is provided with a screw hole 11, the screw hole 11 is screwed with a covering screw 5, the folding edge 10 is buckled with a movable front cover plate 2, preferably, the front cover plate 2 is provided with a covering hole 4 that cooperates with the covering screw 5, The cover hole 4 is in the shape of a table tennis racket, the handle of the upper table tennis racket is tightly matched with the threaded part of the cover screw 5, and the plate of the lower table tennis racket is loosely matched with the nut of the cover screw 5; the body 1 and the upper and lower plates 3 are provided with a KO hole 6, the KO hole 6 is a circular ring protruding to one side, and the circular ring is provided with a circular tail 9 connected to the inner and outer sides, and the upper and lower plates 3 and the left and right plates are provided with two KO holes 6 arranged side by side, the circular ring protrudes outward, the circular tail 9 is provided with a pair of facing inward and outward near the front side, and the circular tail 9 is provided with an outward one near the rear side; the rear plate 7 is provided with a KO hole 6 arranged in the middle of the entire surface, and the circular ring protrudes inward; during installation, according to the outer diameter of the connecting line, the inner ring or convex ring on the KO hole 6 is pried open and flushed from the circular tail to minimize unnecessary gaps and prevent mosquitoes or small animals from entering the junction box.

[0026] The above-mentioned junction box for outdoor power system is made of galvanized sheet. In order to improve the bonding strength of the joint, the upper and lower plates 3 are connected to the body 1 by single-point welding.

[0027] In order to improve the anti-static effect, the surface of the junction box for the outdoor power system is sprayed with an ANSI gray polyester powder anti-static layer, which also improves the anti-rust and anti-corrosion performance of the junction box.

[0028] When installing and using, first lift the front cover plate 2 upwards, align the cover hole 4 with the nut of the cover screw 5 along the cover screw 5 on the folded edge 10 of the body 1, and remove the front cover plate 2; according to the outer diameter of the on-site wiring, if necessary, the wiring is also covered with a sheath, and the KO holes 6 on the upper and lower left and right sides of the wiring box for the outdoor power system that need to pass the line are flushed along the round tail 9. When the outer diameter of the wiring including the sheath is smaller than the middle circle of the KO hole 6, only the inner middle circle is flushed out. When the wiring including the sheath is larger than the middle circle, the middle circle is flushed out together with the ring. A trade-off is needed to prevent the gap from being too large after the wiring is passed, so that mosquitoes or small animals can drill into the gap. Then, pre-drill fastening screw holes on the horizontal or vertical mounting body, fix the screw holes 11 of the rear plate 7 of the junction box to the mounting body with screws, and then connect the connecting wires in the junction box according to the prefabrication requirements. Then, align the covering hole 4 on the front cover 2 with the covering screw 5 and insert it. Then, pull the front cover 2 downward slightly to make the covering hole 4 of the front cover 2 fit tightly with the covering screw 5. If the gap between the covering screw 5 and the front cover 2 is large, tighten the covering screw 5 until it is clamped.
