Embodiment Construction

[0019] The invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown: a six-way cascaded fast cable lead-in device, including a Unicom section 2, the Unicom section 2 guides the cable into the joint to protect the cable outside the entire joint, and can limit the explosion space to the Unicom section when it explodes , to reduce the damage to the outside. A rubber ring 6 is installed inside the Unicom joint 2, and the rubber ring 6 has a fastening effect on the connected cables, and can prevent external impurities, water and explosive gas from entering the inside of the joint; three holes are opened on the rubber ring 6, wherein There are two small holes and one large hole, and rubber rods 7 of corresponding sizes are installed in the three holes. When in use, pull out the rubber rod 7 and insert the cable; the large hole in the three holes is used as the main cable The co...

Abstract

The invention discloses a six-way cascading rapid cable entry device which comprises a link joint (2). A rubber ring (6) for fastening a cable is installed inside the link joint. Three holes are formed in the rubber ring. A steel plug board II (5) is installed at one end of the rubber ring. A steel plug board I (4) adjacent to the steel plug board II is installed inside the link joint. A steel gasket (3) is installed on one side of the steel plug board I. The steel gasket is connected with a compression nut (1) capable of extruding and fastening the rubber ring. The six-way cascading rapid cable entry device has the advantages that bolt-free quick plugging connection of at most four electrical devices with A1-type anti-explosion quick connectors can be achieved, meanwhile, the devices are in cascade connection through the anti-explosion quick connectors, the installation and maintenance efficiency of explosive-proof electrical products is improved, and labor intensity is lowered. The six-way cascading rapid cable entry device is internally provided with a high-intensity inflaming-retarding Kevlar weaving layer, the explosive gas volume inside the six-way cascading rapid cable entry device is decreased, and the anti-explosion performance of the six-way cascading rapid cable entry device is improved.

Description

technical field [0001] The invention relates to a cable lead-in device, in particular to a six-way cascade fast cable lead-in device, which belongs to the field of lead-in devices. Background technique [0002] The junction box is one of the electrical auxiliary materials. Since the wires used in the equipment have to pass through the wire tube, a junction box is used at the wire joint to solve the problems of the length of the line or the corner of the wire tube. The junction box is used as a transition device to connect with the wire tube, so that the wires in the wire tube Connect them in the box to protect the wires and connect the wires. [0003] The quick connector is an accessory for connecting products. By using the quick connector, the products can be seamlessly connected. According to the type, quick connectors can be divided into quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure...
