When the distribution box is specifically arranged, as shown in fig. 1 and 5, the heat dissipation plates 170 are arranged on two sides of the distribution box assembly 10, the dustproof nets 171 are arranged on the inner sides of the heat dissipation plates 170, the heat dissipation plates 170 are provided with heat dissipation ports, the heat dissipation ports of the heat dissipation plates 170 are inclined downwards, the probability that foreign matters fall into the heat dissipation plates 170 is reduced, and through the arrangement of the dustproof nets 171, objects such as dust and winged insects are prevented from entering the box body 110 to influence the operation of the distribution box.

Referring to fig. 2 and 4, the safety assembly 100 includes a mounting plate 140 and an indicator lamp 180, the mounting plate 140 is mounted inside the case 110 by screws, the electric components 130 are mounted on a side wall of the mounting plate 140, and the indicator lamp 180 is mounted on a side wall of the door 120. Through the arrangement of the mounting plate 140, when the distribution box is maintained, the screws can be turned off, and the mounting plate 140 and the electric element 130 can be taken out of the box body 110, so that the maintenance is more convenient; through the setting of pilot lamp 180, can understand the behavior of block terminal more directly perceived.

Meanwhile, the side wall of the box door 120 is provided with the observation window 111, the observation net 111 is arranged to be a toughened transparent anti-theft window, the camera 270 is installed in the middle of the electrical element 130, the position, adjacent to the observation window 111, of the middle of the electrical element 130, the lens of the camera 270 corresponds to the observation window 111, if an abnormal condition occurs, the camera 270 shoots the field condition through the transparent observation window 111, and the camera 270 is arranged inside the box body 110, so that the safety of the camera 270 is improved.

Referring to fig. 3, 4 and 6, the anti-theft assembly 200 includes a screw 210, two bearing blocks 220, two nut connecting blocks 230, a stop block 240, a first door lock 250 and a second door lock 260, the two bearing blocks 220 are respectively installed on the top wall and the bottom wall of the box body 110, the screw 210 is rotatably installed between the bearing blocks 220, the nut connecting block 230 is threadedly installed in the middle of the screw 210, the nut connecting block 230 is welded on the side portion of the box door 120, the nut connecting block 230 is integrally installed with the box door 120, the stop block 240 is welded on the side portion of the screw 210, the first door lock 250 is installed on the right side of the outer wall of the box door 120, and the second door lock 260 is installed on the side portion of the box body 110 adjacent to the box door 120.

The second door lock 260 is a safety rotating tongue lock, a blocking piece 261 is rotatably connected to the end of the second door lock 260, and the blocking piece 261 is attached to the stop block 240 after rotation. The screw rod 210 is used as a rotating shaft of the door 120, the screw rod 210 can rotate through the arrangement of the bearing seat 220, the door 120 is connected with the screw rod 210 through the nut connecting block 230 in an installing manner, when the door 120 is normally rotated, the nut connecting block 230 rotates on the screw rod 210, and simultaneously the nut connecting block 230 can slide up and down on the screw rod 210, but because the screw rod 210 is arranged inside the box body 110, the height of the door 120 is fixed, therefore, the nut connecting block 230 cannot rotate independently, if the door 120 is desired to rotate, only the screw rod 210 can rotate and rotate, when the door 120 is pulled, the brake block 240 needs to rotate clockwise, because when the second door lock 260 is in a closed state, the blocking piece 261 is horizontal, so that the brake block 240 is blocked by the blocking piece 261, the screw rod 210 is blocked, the door 120 cannot rotate, therefore, if only the first door lock 250 is opened, the second door lock 260 is closed, the box still cannot be opened.

With the above arrangement, referring to fig. 1 and 4, the sliding groove 160 is embedded in the side wall of the box door 120, the pressure sensor 280 is installed on the inner wall of the sliding plate of the sliding groove 160, and the alarm 290 is installed on the inner wall of the box body 110. If the thief does not know the function of the second door lock 260, even if the first door lock 250 is pried open, the door 120 still cannot be opened, and at this time, if the thief pulls the pull groove 160 to open the door 120, due to the arrangement of the pressure sensor 280, the pressure sensor 280 senses a pulling force exceeding a normal pulling force range, and a signal is generated to the alarm 290, so that the alarm 290 gives an alarm.

Specifically, this thief-proof formula prepayment formula low voltage distribution box's theory of operation: during the use, open first lock 250 and second lock 260, when second lock 260 was opened, separation blade 261 truns into vertically for brake pads 240 is not blocked, and pulling kerve 160 this moment, chamber door 120 drive nut connecting block 230 and rotate, because chamber door 120 is highly fixed, nut connecting block 230 can't rotate on lead screw 210, and then drives lead screw 210 whole rotation, and then opens chamber door 120 smoothly. According to the scheme, the second door lock 260 is arranged to hide the distribution box, the screw rod 210 is used as a rotating shaft of the box door 120, and the rotation of the box door 120 is limited by the matching of the brake block 240 and the blocking piece 261 according to the characteristic of the rotation principle of the screw rod 210. And through the cooperation of pull groove 160, pressure sensor 280 and siren 290, judge and warn abnormal conditions, improved the theftproof performance of block terminal.

It should be noted that: the model specifications of the indicator light 180, the camera 270, the pressure sensor 280 and the alarm 290 need to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art, so detailed description is omitted.

The power supply of the indicator light 180, the camera 270, the pressure sensor 280 and the alarm 290 and their principles will be clear to the skilled person and will not be described in detail here.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
