[0002] In industrial sectors such as petroleum, chemical, metallurgy, and municipal engineering, as well as in special operations involving confined spaces, hot work, and blind flange installation / removal, workers carry various gas detection and video monitoring devices. These devices typically come with fixed-length cables. However, the complex on-site environment makes these fixed-length cables unsuitable for long distances and high altitudes, and they cannot be customized to different environments. Furthermore, the fixed-length cables are integrated with the equipment, making them inseparable and inconvenient to carry, thus increasing the burden on operators. General cable connectors often fail to meet the explosion-proof performance requirements of explosion-proof environments, especially in Class IIC locations involving the leakage of hazardous gases such as hydrogen and acetylene.

[0003] Currently, explosion-proof connectors on the market are generally large in size, inconvenient to carry, and belong to the non-sparking explosion-proof type. They have complex wiring and high cost, and have a small number of built-in cable cores, and the number of cores cannot be customized. They are only suitable for connecting instrument and meter circuits with thin wire diameters. Utility Model Content

The socket housing 1 and the pin housing 11 are made of aluminum alloy.

[0028] This embodiment is as follows: The explosion-proof multi-core quick-connect device mainly includes a socket component and a plug component. The socket component includes a socket housing 1, a first locking connector 2, a first rubber plug 3, a socket pin 4, and a socket screw ring 7. The socket pin 4 is threaded inside the socket housing 1, and its metal core 5 is connected to the first cable 9. The first rubber plug 3 on the outside of the first cable 9 is located inside the socket housing 1. The socket housing 1 is threadedly connected to the first locking connector 2. The first locking connector 2 presses the first rubber plug 3 to hold the first cable 9 tightly, achieving sealing and explosion-proof functions. A socket screw ring 7 is provided on the outside of the socket housing 1, and a socket protective cover 16 is connected to the socket housing 1. The two are threadedly connected, and the thread length meets the requirements of the explosion-proof thread surface. A second rubber gasket 17 is provided between the socket housing 1 and the socket protective cover 16. At the same time, the socket protective cover 16 is connected to the first locking connector 2 through a first hanging chain 18. The first hanging chain 18 is fixed to the socket protective cover 16 with a first screw 19 and to the first locking connector 2 with a second screw 20.

[0029] The plug assembly includes a pin housing 11, a second locking connector 12, a second rubber plug 13, and a plug pin 14. The plug pin 14 is threadedly installed inside the pin housing 11. The plug pin metal core 15 is connected to the second cable 10. The second rubber plug 13, located outside the second cable 10, is inside the pin housing 11. The pin housing 11 is threadedly connected to the second locking connector 12, which presses against the second rubber plug 13 to secure the second cable 10. A plug protective cover 21 is connected to the pin housing 11 via a threaded connection. A third rubber gasket 22 is placed between the pin housing 11 and the plug protective cover 21. The plug protective cover 21 is connected to the second locking connector 12 via a second chain 23. The second chain 23 is secured to the plug protective cover 21 with a third screw 24 and to the second locking connector 12 with a fourth screw 25.

[0030] When the socket component and plug component are mated, the socket housing 1 and the pin housing 11 are connected by the stop mating surface 8. The socket pin 4 and the plug pin 14 are connected to achieve electrical contact. The socket screw ring 7 is screwed to the pin housing 11 and presses the first rubber gasket 6 to ensure a reliable connection between the plug and socket, meeting the IP66 protection requirements. At the same time, the explosion-proof requirements are met through the stop mating surface 8 and the threaded connection. The socket housing 1 and the pin housing 11 are made of aluminum alloy, which has the advantage of being lightweight. The socket screw ring 7 and the surface of the socket and plug protective cover are designed with a mesh texture for easy manual tightening and disassembly.

[0031] In use, firstly, the number of cores in the socket pins 4 and plug pins 14 is customized according to actual needs to meet different circuit and signal transmission combinations. Then, after removing the sheath of the first cable 9, its internal wires are precisely soldered to the metal core 5 of the socket pin, ensuring a firm solder joint without any issues such as poor soldering or short circuits. Similarly, the sheath of the second cable 10 is removed and soldered to the metal core 15 of the plug pin. Next, the socket pins 4 are screwed into the socket housing 1 to secure them, while the plug pins 14 are screwed into the pin housing 11. Next, the first rubber plug 3 is placed inside the socket housing 1, allowing the first cable 9 to pass through the first rubber plug 3. Then, the socket housing 1 is threadedly connected to the first locking connector 2, and the first locking connector 2 is rotated until it presses against the first rubber plug 3, thereby holding the first cable 9 tightly to achieve a sealing and explosion-proof effect. For the plug component, the second rubber plug 13 is placed inside the pin housing 11, allowing the second cable 10 to pass through the second rubber plug 13. Then, the pin housing 11 is threadedly connected to the second locking connector 12, and the second locking connector 12 is rotated to press against the second rubber plug 13 to hold the second cable 10 tightly.

[0032] When connecting cables or equipment, first open the socket protective cover 16 and the plug protective cover 21 respectively, and accurately align the socket housing 1 with the pin housing 11, ensuring that the socket pin 4 and the plug pin 14 are fully inserted to achieve electrical continuity. Then, rotate the socket screw ring 7 to screw it into the pin housing 11. During the screwing process, the socket screw ring 7 gradually presses against the first rubber gasket 6 to ensure a tight connection between the plug and the socket, preventing loosening and meeting the IP66 protection level requirements. This also ensures that the entire connection device meets relevant standards for explosion protection and can be used in locations with Class IIC or higher hazardous gas leaks. During use, since the socket protective cover 16 and the plug protective cover 21 are connected to the corresponding locking connectors via chains, the protective covers will not be lost when not in use, facilitating future use.

Many modifications and variations can be made based on the content of this specification.
