Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically to an explosion-proof network connector. Background Technology

[0002] Network connectors are key hardware components in network communication, and their past technological development has primarily revolved around physical connections and signal transmission. Integration is currently one of the technological challenges and development trends for network connectors. While meeting the requirements of conventional physical connections and signal transmission, they also need to take into account environmental adaptability requirements such as explosion-proof and waterproof properties.

[0003] Explosion-proof connectors are key hardware components in explosion-proof electrical equipment, their technology primarily based on the integration of explosion-proof principles and connector design. They are mainly used in hazardous environments such as oil and gas, chemical, and dusty environments. Through a high-strength housing and precision flange clearance design, explosion-proof connectors allow internal explosions to occur while confining the flame and high temperature within the housing, utilizing the "flame channel asphyxiation effect" to prevent the explosion from propagating to the external environment. Typical applications include high-power equipment such as motors and switchgear. Currently, explosion-proof connectors are mainly designed for power transmission or other high-voltage, high-current applications.

[0004] In actual production, the insertion and removal of network connectors, which are low-voltage and low-current connectors, still generate electrical sparks, posing a safety hazard in flammable gas environments. Utility Model Content

[0005] The purpose of this invention is to design a new structure to achieve explosion-proof and waterproof functions for network connectors, ensuring safe insertion and removal of network connectors in flammable gas environments.

[0006] To achieve the above objectives, this application adopts the following technical solution: An explosion-proof network connector, comprising a socket and a plug, respectively: The tube body, the connecting sleeve connected to the tube body, the housing connected to the tube body inside the connecting sleeve, and the contact element inside the housing are interlocked and locked together. An explosion-proof gap surface is provided between the housing and the connecting sleeve after connection. The housing and the connecting sleeve rotate relative to each other.

[0007] In the above technical solution, the shell and the tube are connected by explosion-proof threads, and the shell and the connecting sleeve are connected by explosion-proof threads.

[0008] In the above technical solution, a sealing body is provided inside the tube, and a tightening nut is provided on the tube end corresponding to the sealing body, and the tightening nut is in contact with the sealing body.

[0009] In the above technical solution, the tightening nut can compress the sealing body by rotation.

[0010] In the above technical solution, a step is provided inside the tube, and one end of the sealing body is placed on the step. The compressed sealing body expands radially.

[0011] In the above technical solution, when the plug and socket are inserted, a sealed cavity is formed between the two sealing bodies inside the tube.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This application creates an explosion-proof, sealed space within the housing for the network plug and bidirectional network socket. All gaps around the sealed space meet the requirements of GB / T3836.2-2021, confining flames and high temperatures within the housing to prevent the ignition of flammable gases in the environment. It also creates a waterproof space for the network plug and bidirectional network socket, solving the problem that traditional network connectors cannot be waterproofed. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0016] like Figure 1As shown, the plug consists of a plug housing 1, a connecting sleeve 2, a connecting sleeve set screw 3, a straight tube 4, a sealing body 5, a tail nut 6, a pressure plate 7, a network plug 8, a sealing ring 9, an insulator 10, a straight tube set screw 11, an O-ring 12, a washer 13, a screw 14, and a pressure sleeve 18. The connecting sleeve set screw 3, the straight tube set screw 11, the washer 13, and the screw 14 are standard stainless steel parts; the O-ring 12 is a standard silicone rubber part; the network plug 8 is a standard RJ45 crystal head; the plug housing 1, the connecting sleeve 2, the straight tube 4, the tail nut 6, the pressure plate 7, and the pressure sleeve 18 are made of hard anodized aluminum alloy or passivated stainless steel; the sealing body 5 and the sealing ring 9 are made of silicone rubber; and the insulator 10 is made of PA66 nylon.

[0017] like Figure 2 As shown, the socket consists of a socket housing 15, a sealing gasket 16, a straight tube set screw 11, a straight tube 4, a wire sealing body 5, a tail nut 6, a wire clamping plate 7, a washer 13, a screw 14, a clamping sleeve 18, a two-way network socket 17, and a network plug 8. The socket housing 15, straight tube 4, tail nut 6, wire clamping plate 7, and clamping sleeve 18 are made of silicone rubber. The straight tube set screw 11, washer 13, and screw 14 are standard stainless steel parts. The two-way network socket 17 is a standard RJ45 dual-socket assembly, and the network plug 8 is a standard RJ45 crystal head.

[0018] like Figure 1 The assembly process of the plug is as follows: the outer side of the plug housing 1 has a groove, and the sealing ring 9 is inserted into the groove; the inner side of the straight tube 4 has a groove, and the O-ring 12 is inserted into the groove; the connecting sleeve 2 is inserted into the outer side of the plug housing 1, and the network plug 8 and the insulator 10 are inserted into the inner side in sequence. After the straight tube 4 is screwed in, the straight tube 4 and the plug housing 1 will clamp and fix the connecting sleeve 2, the network plug 8, and the insulator 10; a straight tube set screw 11 is installed on the straight tube 4, and a connecting sleeve set screw 3 is installed on the connecting sleeve 2; a washer 13, a sealing body 5, and a pressure sleeve 18 are inserted into the tail of the straight tube 4 in sequence, and the tail nut 6 is screwed on to clamp and fix the washer 13, the sealing body 5, and the pressure sleeve 18; a pressure plate 7 is installed on the fixing wing of the tail nut 6 and fixed with a screw 14.

[0019] As shown in Figure 2, a bidirectional network socket 17 is installed from the front of the socket housing 15 and fixed with glue; a network plug 8 is inserted from the rear of the socket housing 15 and connected with the bidirectional network socket 17; a sealing gasket 16 is installed from the rear of the socket housing 15; an O-ring 12 is installed in a groove on the inner side of the straight tube 4; a straight tube set screw 11 is installed on the straight tube 4; a gasket 13, a sealing body 5, and a pressure sleeve 18 are sequentially installed at the tail of the straight tube 4, and the tail nut 6 is screwed on to clamp and fix the gasket 13, the sealing body 5, and the pressure sleeve 18; a pressure plate 7 is installed on the fixing wing of the tail nut 6 and fixed with a screw 14.

[0020] like Figure 3 As described above, when the plug and socket are assembled, the protruding key on the plug housing 1 will preferentially engage with the concave key on the socket housing 15. After engagement, the plug housing 1 and socket housing 15 will be unable to rotate relative to each other. Next, the inner thread of the connecting sleeve 2 engages with the outer thread of the socket housing 15. By rotating the connecting sleeve 2, the plug and socket will move closer to each other. When the end face of the plug housing 1 contacts the step of the socket housing 15, the connecting sleeve 2 will be unable to continue rotating, and the plug and socket will be fully inserted. At this time, the opening of the socket housing 15 will compress the sealing ring 9, achieving the waterproof requirement between the plug and socket. Since the network plugs 8 on both the plug side and the socket side are crimped with network cables, when the connecting sleeve 2 is screwed in, the network plug 8 on the plug side will be connected to the bidirectional network socket 17 on the socket side, and thus the network cable on the plug side will also be connected to the network cable on the socket side.

[0021] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
