[0002] A coal mine is an area where humans extract coal resources in a coal-rich mining area. It mainly includes six major systems: coal mining system, tunneling system, electromechanical system, transportation system, ventilation system, and drainage system. The electromechanical system includes circuit layout and equipment connection. Because there is gas at the bottom of the mine, the connection of electromechanical equipment should avoid generating sparks and exposed wire connection points. The use of power strips is strictly prohibited. Therefore, wiring devices are required for wiring.

[0003] The existing wiring device has the following defects: First, when connecting to the coal mine's electromechanical equipment, the connection of the wires is not convenient enough. It is necessary to twist and connect the two exposed copper wires of the wires, and then wrap them with insulating tape for protection. The above method is cumbersome and has poor stability. Second, the sealing is poor. Impurities mixed in the coal mine can easily fall into the wiring device, causing wear on the internal structure. Summary of the Invention

The gas injected through the injection conduit can enter the air guide cavity and push the stroke block to achieve the purpose of separating the stroke block from the limiting groove.

[0011] A further feature is that the air guide cavity still exists when the inner pressure block abuts against the step.

[0012] A further feature is that an extension block is fixedly provided on the outer periphery of the copper sleeve, and when the extension block abuts against the main body of the device, the position of the travel block corresponds to that of the limiting groove.

[0015] Further configuration includes: a through slot, a first through hole, and a second through hole sequentially formed within the upper shifting block, the intermediate sealing block, and the lower contact block, creating a continuous placement groove; a conductive spring and a conductive ball are placed within the placement groove, with the conductive ball moving towards the wire hole under the elastic force of the conductive spring; a conductive groove is provided within the limiting groove for the conductive ball to partially extend into and form a conductive connection; a limiting block is fixedly installed at the opening of the placement groove to prevent the conductive ball from detaching from the placement groove; a first lead hole is provided within the upper shifting block, connecting the placement groove and the travel groove; a wire outlet is provided within the inner fixing seat, extending to the surface of the device body and sealingly housing a conductive wire, which is connected to an external control terminal; a second lead hole is also provided on the inner fixing seat, connecting the travel groove and the wire outlet; the conductive spring and the conductive wire are connected via a wire to achieve signal output.

A conductive inner base plate is fixedly mounted on the conductive outer base plate. A conductive support block connected to the copper sleeve connector is fixedly mounted at the bottom of the conductive inner base plate.

Each of the two conductive inner arms consists of a bottom bending section, a middle arc-shaped section, and a top bending section. The middle arc-shaped section is adapted to the side surface of the copper sleeve connector. Two second connecting plates are fixedly mounted on the conductive inner base plate. A conductive contact arm connected to the copper sleeve connector is fixedly mounted on each of the two second connecting plates. The two conductive contact arms have a contact bending section connected to the copper sleeve connector.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In this invention, the main body of the device is provided with two inlet terminals and two outlet terminals, both of which are used for power supply cable insertion. The wires are easily inserted into the cable passage holes by means of cylindrical copper sleeves at their ends, and the copper sleeves are limited by contact with a limiting unit. Thus, the wires only need to be inserted into the cable passage holes, and then the limiting unit limits the wires, making the fixing method convenient and providing excellent stability. The conductive base can electrically connect the wires inserted into the corresponding inlet and outlet terminals; the copper sleeve connector on the copper sleeve can contact the conductive connection unit, which can both limit the copper sleeve connector and conduct electricity. The first sealing groove and the first graphite sealing ring improve the device's sealing performance.

[0019] 2. In this invention, the travel block within the limiting unit moves towards the wire hole side under the elastic action of the inner spring, and achieves the function of limiting the wire by extending into the limiting groove on the copper sleeve; the two guide arms on the travel block guide the travel block, allowing it to move longitudinally stably, while the space between the two guide arms allows the inner spring to extend in, thus limiting the inner spring; the step prevents the travel seat from dislodging from the travel groove under the elastic action of the inner spring by abutting against the inner pressure block on the transverse pressure block; the air injection chamber, injection conduit, and first air guide pipe inject gas, which enters the air guide chamber and pushes the travel block to separate it from the limiting groove, facilitating the removal of the wire.

[0020] 3. In this invention, when the inner pressure block abuts against the step, the air guide cavity still exists, thus preventing the situation where gas cannot be injected into the air guide cavity and thus cannot push the stroke block.

[0021] 4. In this invention, an extension block is provided on the outer periphery of the copper sleeve. When the extension block abuts against the main body of the device, the position of the stroke block corresponds to that of the limiting groove, thereby facilitating the insertion of the stroke block into the limiting groove.

[0022] 5. In this invention, a second sealing groove and a second graphite sealing ring are provided for further sealing, and the transverse pressure block can compress the second graphite sealing ring.

[0023] 6. In this invention, the travel block is composed of an upper displacement block, an intermediate sealing block, and a lower contact block fixed in sequence. An auxiliary groove is provided between the upper displacement block and the intermediate sealing block. An auxiliary push block and an auxiliary spring are provided in the auxiliary groove. The auxiliary groove is inclined, and the auxiliary push block can slide obliquely along the auxiliary groove. The auxiliary spring can provide a force for the auxiliary push block to move towards the intermediate sealing block. The intermediate sealing block is made of rubber, so that the intermediate sealing block can better contact the limiting groove under the push of the auxiliary push block to improve the sealing performance. The intermediate sealing block and the lower contact block are both inclined on the side near the surface of the device body, and respectively form a first inclined surface and a second inclined surface. This allows the wire to contact the first inclined surface and the second inclined surface during the insertion into the wire hole, and gradually push the travel block open for smooth insertion.

[0024] 7. In this invention, a conductive spring and a conductive ball are provided in the placement groove. The conductive ball moves toward the wire hole side under the elastic force of the conductive spring and extends into the conductive groove to form a conductive connection. The arrangement of the first lead hole, the outlet hole, the conductive outlet, the second lead hole, and the wire allows the electrical signal generated after the conductive ball contacts the conductive groove to be transmitted to the external control terminal to realize signal output, which is used to determine whether the wire is stably extended into the wire hole.

[0025] 8. In this invention, the conductive outer base plate in the conductive connection unit is fixed on the conductive base. The first connecting plate is used to connect the conductive outer plate. The conductive outer plate can contact the conductive inner arm to improve conductivity and also play a limiting role. The conductive inner base plate is fixed on the conductive outer base plate. The conductive support block on the conductive inner base plate can contact and support the copper sleeve connector. A conductive cavity is formed between the two conductive inner arms for the copper sleeve connector to pass through. The middle arc section on the conductive inner arm is adapted to the side surface of the copper sleeve connector to expand the contact area. The second connecting plate is used to connect the conductive contact arm. The contact bending section on the conductive contact arm can better connect with the copper sleeve connector.

[0047] The working principle of this embodiment is as follows:

[0048] During installation, the wire is inserted into the corresponding inlet 12 or outlet 13. The copper sleeve 21 on the wire extends into the wire passage hole 32 of the inner fixing seat 31. The first graphite sealing ring 342 contacts the copper sleeve 21 for a first seal. As the copper sleeve 21 gradually extends into the wire passage hole 32, it contacts the first inclined surface 571 and the second inclined surface 572 on the intermediate sealing block 52 and the lower contact block 53, and pushes the travel block aside. Then it steadily and continuously extends into the wire passage hole 32. The first graphite sealing ring 342 contacts the copper sleeve 21 for a second seal. Until the extension block 23 abuts against the main body 11 of the device, at this time, the travel block and the limiting groove 211 are in the same position. Under the elastic action of the inner spring 44, the travel block extends into the limiting groove 211 to achieve the function of limiting the wire. The fixing method is convenient and the fixing stability is good. Meanwhile, the intermediate sealing block 52 can better contact the limiting groove 211 under the elastic force of the auxiliary spring 56, thereby improving the sealing performance. At the same time, the copper sleeve connector 22 will also extend into the conductive cavity between the two conductive inner arms in the conductive connection unit. The lower end of the copper sleeve connector 22 is supported by the conductive support block 75, the two sides are in contact with the middle arc section 762, and the end is in contact with the conductive contact arm 78. Then, the copper sleeve connector 22 contacts the conductive base 33, and the conductive base 33 is used to conductively connect the wires inserted into the corresponding inlet end 12 and outlet end 13. In addition, the conductive ball 63 placed in the slot 61 moves toward the wire hole 32 under the elastic force of the conductive spring 62 and extends into the conductive slot 64 to form a conductive connection. The arrangement of the first lead hole 651, the outlet hole 652, the conductive outlet, the second lead hole 653 and the wire allows the electrical signal generated after the conductive ball 63 contacts the conductive slot 64 to be transmitted to the external control terminal to realize signal output. The control terminal can determine that the wire is stably extended into the wire hole 32 at this time.

[0049] During disassembly, gas is injected through an injection conduit. The injected gas passes through the gas injection chamber 47 and the first gas guide tube 48 in sequence into the gas guide chamber 462, and then pushes the stroke block to separate the stroke block from the limit groove 211, so as to facilitate the removal of the wire.
