Referring to fig. 1-5, a junction box of a mining electrical device comprises a junction box body 1, a sliding groove 2 is formed in the front face of the junction box body 1, a movable groove 4 is formed in the bottom of an inner cavity of the junction box body 1, a wiring bar 3 is slidably mounted on the inner side face of the movable groove 4, a pressing plate 6 is fixedly mounted on the top of the wiring bar 3, a spring 19 is fixedly connected to the bottom of the wiring bar 3 and connected with the bottom of the junction box body 1, a box cover 9 matched with the sliding groove 2 is movably mounted on the top of the junction box body 1, a rubber sealing gasket matched with the sliding groove 2 is bonded to the bottom of the side face of the box cover 9, a tension spring 8 is fixedly connected to the right side face of the inner cavity of the sliding groove 2, and a connecting plate 10 connected with the other end of the tension spring 8 is fixedly connected to the bottom of the inner side of the box cover 9.

The inside fixed mounting of terminal block 3 has electric connection contact board 20, and the bottom fixed mounting of terminal box body 1 inner chamber has with electric connection contact board 20 matched with to lead electrical pillar 21, leads the contact between electrical pillar 21 and the electric connection contact board 20 and be the flat contact, makes the area of contact between the two great like this, and then reduces the resistance between the two to make the conductivity of equipment not influenced.

The bottom of the inner chamber of lid 9 has been seted up communicating groove 11, the inside movable mounting in communicating groove 11 has sliding block 12, the bottom fixedly connected with main connection rope 14 of sliding block 12, the lateral wall of terminal box body 1 has been seted up and has been run through chamber 15, the inside movable mounting that runs through chamber 15 has and main connection rope 14 matched with gyro wheel 16, the vice rope 17 of connecting of side fixedly connected with of main connection rope 14, the bottom movable mounting of terminal box body 1 inner chamber has with 3 side matched with elasticity cards 18 of line of connection, the other end of vice connection rope 17 extends to the inside of terminal box body 1 and is connected with the side of elasticity card 18, the quantity of elasticity card 18 is two, two elasticity cards 18 are located the both sides of line of connection 3, the other end of main connection rope 14 extends to the inside of terminal box body 1 and is connected with the side of another elasticity card 18.

An S-pole magnet 7 is fixedly installed on the side face of the box cover 9, an N-pole magnet 13 matched with the S-pole magnet 7 is fixedly installed on the left side face of the box cover body 1, a sealing plate 5 is fixedly connected to the bottom of the right side of the box cover 9 and is used for sealing, the attraction force between the S-pole magnet 7 and the N-pole magnet 13 is smaller than the tension force generated after the tension spring 8 deforms, so that when the box cover 9 is opened, the residual action force of the tension force between the tension spring 8 and the magnet is overcome by the transverse action force of the main connecting rope 14 on the tension force of the sliding block 12, and the box cover 9 can be kept in an opened state, and it needs to be noted that a manual support rod matched with the wiring bar 3 is installed inside the box cover body 1 and is not shown in the figure, and the manual support rod can prevent the wiring bar 3 from returning to the original position due to the pressing force of a screwdriver when the wiring bar 3 is connected, the case cover 9 is automatically closed, after the connection is completed, the manual support rod can be taken away, when people manually push the case cover 9, the right side surface of the communication groove 11 drives the sliding block 12 to move at the moment, the main connection rope 14 and the auxiliary connection rope 17 are driven to pull, the elastic clamp 18 is separated from the connection row 3, the electric connection contact plate 20 is separated from the conductive column 21, the electric power supply and the electric equipment are disconnected when people overhaul, the N-pole magnet 13 and the S-pole magnet 7 are mutually attracted, the case cover 9 is ensured to be in an open state, a mechanical contact switch can be arranged between the case cover 9 and the sliding groove 2, and an indicator light is connected to the other end of the switch, therefore, under the condition that the box cover 9 is not closed, the indicating lamp is in a normally-on state, and people are reminded to press the pressing plate 6.

Set up extension spring 8, press the clamp plate 6, make people after the maintenance is accomplished, press the clamp plate 6, make electric connection contact plate 20 and lead electrical pillar 21 to connect, make elasticity card 18 block line bank 3 simultaneously, and then make main connection rope 14 and vice connection rope 17 return to the normal position, and then make sliding block 12 produce power to the lid 9 rightwards, thereby overcome the appeal of N utmost point magnet 13 and S utmost point magnet 7 with the power of extension spring 8, under extension spring 8' S effect, make lid 9 carry out self-closing, prevent that people from forgetting to close lid 9 and lead to when gas enters into the terminal box inside, lead to the condition of explosion when appearing the short circuit condition.

Set up activity groove 4, electric connection contact plate 20, lead electrical pillar 21 for people are after the maintenance is accomplished, if forget to press according to the time of pressing board 6, guarantee that the row of connecting 3 can't be connected electrically, and then make the power supply can not supply power for electrical equipment, make the condition that the short circuit can not appear even not closing of lid 9.

The working principle is that when people need to overhaul the electrical equipment of the mine, the box cover 9 is manually pushed, at the moment, the tension spring 8 is deformed, at the moment, in the moving process of the box cover 9, the right side of the communicating groove 11 is clamped with the sliding block 12, the sliding block 12 moves towards the left side until the N pole magnet 13 and the S pole magnet are contacted and attracted with each other, the sliding block 12 pulls the main connecting rope 14 at the moment, the elastic card 18 at the right side is inclined, the elastic card 18 at the right side is separated from the clamping groove at the wiring row 3, the auxiliary connecting rope 17 is pulled at the same time, the elastic card 18 at the left side is separated from the clamping groove at the wiring row 3, at the moment, the elastic card 18 is clamped at the side of the wiring row 3, meanwhile, the elastic force of the spring 19 acts on the wiring row 3, the electric connecting contact plate 20 is separated from the conductive column 21, after the overhaul is finished, people need to press the wiring row 3 through the press plate 6, so that electric connection contact plate 20 contacts with leading electrical pillar 21, simultaneously, elasticity card 18 will block in the draw-in groove department of row of connecting 3, and main connection rope 14 is in the lax state this moment, and then makes sliding block 12 originally disappear to the power of right side effect on lid 9 to make the effort of extension spring 8 department be greater than the power between N utmost point magnet 13 and the S utmost point magnet 7, and then make lid 9 close under the effect of extension spring 8.
