Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The mining flameproof cable connector comprises a plug assembly 1 and a socket assembly 2 which are mutually spliced, wherein the plug assembly 1 and the socket assembly 2 are connected through a connecting bolt 3.
As shown in fig. 2 and 3, the socket assembly 2 includes a socket housing 21, a socket insulator 22 mounted inside the socket housing 21, a plurality of male pins 23 penetrating through and mounted inside the socket insulator 22, a connecting rod 24 penetrating through and fixed to the middle inside the socket insulator 22, a socket plugging ring 25 clamped between the socket insulator 22 and the inside of the socket housing 21 and made of an insulating material, a fastening screw 26 penetrating through and mounted on the middle of one end of the socket housing 21 away from the plug assembly 1 and in threaded connection with the connecting rod 24, and a conductive plug 28 in threaded connection with one end of the connecting rod 24 away from the fastening screw 26. The quick-inserting convex needle 23 is inserted from one side of the socket insulator 22 towards the socket plugging ring 25, the socket plugging ring 25 plugs the insertion port of the socket insulator 22, and the socket plugging ring 25 is hollowed out to allow the line to be inserted.
As shown in fig. 1 and 4, the socket base 21 includes a socket base 211 sleeved outside the socket insulator 22 and the socket plugging ring 25 and into which the plug assembly 1 is inserted, one end of the socket base 211 away from the plug assembly 1 is fixedly connected with a fixing base 212 tightly attached to the socket plugging ring 25, one end inner side of the fixing base 212 away from the socket base 211 is fixedly connected with a connecting ring 213, the inner side of the connecting ring 213 is fixedly connected with a connecting strip 214 radially arranged along the connecting ring and provided with a middle part for a rod part of the fastening screw 26 to pass through, a sleeve 29 sleeved outside the fastening screw 26 is clamped between the socket insulator 22 and the connecting strip 214, and a second spring washer 5 is clamped between the head of the fastening screw 26 and the connecting strip 214. The sleeve 29 limits the distance between the connection bar 214 and the socket insulator 22, preventing the trouble of the socket insulator 22 being broken due to the excessive screwing of the fastening screw 26. The outer wall in the middle of the connecting rod 24 is provided with an annular groove 241, and the inner side of the socket insulator 22 is injection molded with a limiting block 222 clamped into the annular groove 241, and the connecting rod 24 is limited by the limiting block 222 and moves together with the socket insulator 22.
As shown in fig. 1 and 4, the inner edge of the fixing base 212 is circular, and the inner diameter is equal to the inner diameter of the connecting ring 213 and smaller than the inner diameter of the socket 211, so that the socket plugging ring 25 and the socket insulator 22 need to be clamped in from the end of the socket 211 away from the connecting ring 213, and the socket plugging ring 25 abuts against the fixing base 212 and cannot pass through. After tightening the fastening screw 26, the socket insulator 22 is limited by the fastening screw 26 and cannot fall out of the socket base 21, so that the whole structure is stable and is not easy to loosen. The outer edge of the fixed seat 212 is square and protrudes relative to the sleeve seat 211, and fixing holes 2121 are formed in four corners of the fixed seat 212 in a penetrating manner, so that the socket seat body 21 can be fixed at the electric cabinet frame through bolts. The fixing base 212 is fixedly connected with two arc baffles 215 at each fixing hole 2121, and the arc baffles 215 are fixedly connected with the sleeve base 211. The two arcuate baffles 215 together form a splayed shape and have a side facing away from the nest 211 that is spaced farther apart than a side facing toward the nest 211. The two arc baffles 215 can be clamped in by the head of the bolt, so that the bolt is effectively prevented from being mechanically damaged due to the impact of external force, and coal dust and water cannot accumulate. Meanwhile, the structural strength between the fixing base 212 and the socket base 21 is improved, and the trouble of breakage of the fixing base 212 is avoided.
As shown in fig. 6 and 7, a fastening screw 27 extending into the socket body 22 is screwed to one side of the socket holder 211, and the socket body 22 is provided with a locking groove 221 into which the fastening screw 27 is locked. The end of the clamping groove 221 facing the fixing seat 212 is communicated with the outside, so that the socket insulator 22 can be directly inserted into the socket 211 and the fastening screw 27 is clamped into the clamping groove 221. The fastening screw 27 has an inner hexagonal groove 271 formed at one end of the outer side of the socket 211 and is screwed with a fastening nut 272, a first spring washer 4 is clamped between the fastening nut 272 and the socket 211, and the socket body 21 is provided with a receiving groove 2111 into which the fastening nut 272 is clamped.
