A kind of anti-violence plugging and unplugging electrical equipment junction box

Abstract

The invention discloses an electrical equipment wiring box capable of preventing violent plugging and pulling. The electrical equipment wiring box comprises a sealing bottom box, an opening box and acover plate which are sequentially overlapped and arranged, wherein the upper side and the lower side of the opening box are of an opening structure, and the two sides of the opening box are providedwith a lead-in wire outlet and at least one lead-out wire outlet hole respectively, and the number of the lead-out line holes is set according to actual use conditions; two symmetric sliding rods arearranged on the inner wall of the length direction of the opening box, and a wiring board which is in sliding connection with the two sliding rods is arranged between the two sliding rods; the wiringboard which is connected with the opening box is arranged in a sliding mode, so that the ordered arrangement of the multi-strand combined wire harnesses in the device is facilitated, and meanwhile, awire binding device with an elastic sheet is arranged on the wiring board, and after the installation is completed, the elastic sheet is in contact with a wire harness pipe; and when violent pulling occurs, the wire harness can be quickly inserted into the wire harness tube, and continuous outward pulling of the wire harness can be stopped immediately, so that damage caused by violent pulling is avoided, and loss caused by instantaneous power failure can be avoided to a certain extent when violent events occur.

Description

technical field [0001] The invention relates to electrical engineering technology, in particular to a junction box for electrical equipment that prevents violent insertion and extraction. Background technique [0002] The junction box is an important tool for switching electrical lines for electrical systems and electrical equipment. It is an interface device that provides convenience for wiring and checking lines. There are two main types of junction boxes. One is to use internal terminal blocks. The other is a simple junction box with a circuit board that can realize certain control functions, and the simple junction box mentioned above is the most common tool in the electrical system. [0003] The current junction box has multiple fixed terminals inside. Most of the terminals use winding or extruding methods to fix and connect the wire harness. When the lead-in wire is violently pulled, no matter what the connection method is, it will cause damage to the copper wire and ...

Problems solved by technology

[0003] The current junction box has multiple fixed terminals inside. Most of the terminals use winding or extruding methods to fix and connect the wire harness. When the lead-in wire is violently pulled, no matter what the connection method is, it will cause damage to the copper wire and the overall prolapse of the wire harness

[0004] Chinese Patent Publication No. CN207664244U discloses "a terminal block for quick plugging and unplugging of electrical equipment", which utilizes a pull rod structure to realize fast plugging and unplugging and provide pressure fixed connection, but it still cannot guarantee the fixing effect of the wire harness when it is pulled vigorously by external force , the safety of the electrical system cannot be effectively guaranteed

[0005] At the same time, most of the existing junction boxes use the double-housing splicing method. Since the junction box needs to be fixed after the wiring is completed, during the later maintenance, the operator's operation will be limited when opening a casing for maintenance, which is very inconvenient to operate. After the whole is disassembled, the disassembly and maintenance will cause new problems in the fixed position in the later stage.
