Description

Technical Field

[0001] This utility model relates to the technical field of double-layer protected quick connectors for signal lines of biomass fuel production equipment, specifically a double-layer protected quick connector for signal lines of biomass fuel production equipment. Background Technology

[0002] The double-protected quick connector for signal lines used in biomass fuel production equipment is a device specifically designed for connecting signal lines. It is mainly used to ensure the stability and security of signal transmission, while preventing external environmental interference or damage to the signal lines.

[0003] In existing technologies, industrial signals are generally low-frequency signals, but this production requires high-frequency signals, so the requirements for signal shielding are higher. Generally, in order not to damage the shielding layer, an integrated shielded cable must be selected. For this reason, a shielding interface is designed in the quick connector, and the entire connector area must be covered by an effective conductive metal thin layer. The conductive metal thin layer is connected to the shielded cable, and the connection between the shielding layers at the connector is properly made to complete a shielded and protected quick connector. Signal lines in biomass fuel production equipment are usually used to connect signal lines of sensors, controllers and other equipment to ensure the stability and accuracy of signal transmission.

[0004] However, the production environment of biomass fuel has certain unique characteristics in the existing technology. It often contains flammable and explosive substances such as dust and volatile organic compounds. Traditional signal line connectors mostly use only simple sealing structures, which are difficult to effectively isolate these external explosive factors. Their sealing materials are prone to aging and deformation during long-term use, resulting in a decline in sealing performance. This allows explosive substances to seep into the connector. Once they come into contact with an electrical spark, they can easily cause an explosion, posing a serious threat to the safety of production equipment and personnel. Utility Model Content

[0010] Preferably, the rear end of the second connector is provided with a retaining groove around its perimeter, in which a sealing ring is held, and the rear end of the slot communicates with the retaining groove.

[0011] Preferably, the front end of the plug rod has a first screw hole, and the first connector has a second screw hole at the rear end of the slot. When the plug rod is inserted into the slot, the first screw hole and the second screw hole are parallel.

[0012] Preferably, the inner perimeter of the sealing ring is provided with an arc-shaped opening, which is perpendicular to the slots provided around the first connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention proposes a double-layer protected quick connector for signal lines of biomass fuel production equipment. When connecting the first connector and the second connector, the front end of the second connector is first inserted into the shielding interface at the front end of the first connector. At this time, the connecting end of the inner end of the second connector is inserted into the insertion interface in the middle of the inner side of the first connector, connecting the first connector and the second connector. At the same time, the sealing rings around the outer rear end of the second connector are inserted into the shielding interface, and the sealing rings begin to seal the connection between the first connector and the second connector.

[0023] Please see Figures 1 to 6This utility model provides a technical solution: a first connector 1, with a shielding interface 4 in the middle of its inner side, a plug-in interface 5 in the middle of the inner side of the shielding interface 4, and an annular groove 6 around the outer circumference of the plug-in interface 5, with a plug-in rod 7 fixedly installed around the outer circumference of the annular groove 6; and a second connector 2, with a connecting end 9 in the middle of its inner side, a sealing protective ring 10 fixedly installed around the outer circumference of the connecting end 9, and a slot 11 around the outer circumference of the sealing protective ring 10; cables 3 are simultaneously connected to the middle of the rear ends of the first connector 1 and the second connector 2, and the two sets of cables 3 are respectively connected to biomass fuel production equipment and controller equipment; the connecting end 9 in the middle of the front end of the second connector 2 corresponds to the plug-in interface 5 in the middle of the shielding interface 4 in the middle of the front end of the first connector 1, and the connecting end 9 can be plugged into the shielding interface 4. In the shielding interface 4, the first connector 1 is connected to the second connector 2; the annular groove 6 on the outer ring of the inner insertion interface 5 of the shielding interface 4 corresponds to the sealing and protective ring 10 on the outer ring of the front end 9 of the second connector 2, and the slot 11 on the outer ring of the sealing and protective ring 10 corresponds to the insertion rod 7 on the outer ring of the annular groove 6; the rear end of the second connector 2 is provided with a retaining groove 12, in which the sealing ring 13 is held, and the rear end of the slot 11 communicates with the retaining groove 12; the front end of the insertion rod 7 is provided with a first screw hole 8, and the first connector 1 is provided with a second screw hole 14 on the rear end of the slot 11. When the insertion rod 7 is inserted into the slot 11, the first screw hole 8 and the second screw hole 14 are parallel; the inner side of the sealing ring 13 is provided with an arc-shaped opening 15, which is perpendicular to the slot 11 on the outer ring of the first connector 1.

[0024] In actual use, when connecting the first connector 1 and the second connector 2, first insert the front end of the second connector 2 into the shielding interface 4 at the front end of the first connector 1. At this time, the connecting end 9 at the inner end of the second connector 2 is inserted into the insertion interface 5 in the middle of the inner side of the first connector 1, connecting the first connector 1 and the second connector 2.
