Description
Technical field
The present invention relates to the jockey of electric equipment, specifically a kind of mine explosion-suppression multicore binding post.
Background technology
Known, must be connected with the electric equipment in intrinsic safety case Flameproof box with the binding post of flame proof at inflammable and explosive mine scene, the scene of most all adopts 9 core binding posts to connect, because core number is few, when the core number of needs exceedes 9 cores or when more, will increase the quantity of binding post, not only consume too much terminal, also cause that flameproof enclosure volume and weight increases, make flameproof enclosure become heavy and huge; And existing multicore binding post is all generally that multicore conducting rod is set in the enclosure, in the time of electrical connection, electric equipment in Flameproof box and intrinsic safety case needs to be welded on by connecting line respectively the two ends of conducting rod, not only operates inconvenience but also the solder joint reliability that also easily breaking releasing impact is electrically connected.
Summary of the invention
The object of the present invention is to provide mine explosion-suppression multicore binding post, this binding post can be realized the connection between electric equipment quickly and easily, improves reliability and the explosion insulation performance of electrical connection.
The technical solution adopted for the present invention to solve the technical problems is:
Mine explosion-suppression multicore binding post, comprise junction block and the set casing of threaded engagement, in described junction block, be provided with insulating barrier, the plate face of insulating barrier is provided with one group of through hole, in through hole, be respectively equipped with the cable that stretches out junction block top and bottom, insulating barrier is removed in the position that every cable is positioned at insulation board through hole, and the cable segment periphery of removing insulating barrier is coated with scolding tin; In junction block cavity between described cable and insulating barrier, be filled with epoxy resin.
Further, described junction block bottom is provided with rubber end socket.
Further, described set casing housing is provided with the lock-screw that prevents that set casing from sliding.
The invention has the beneficial effects as follows, give up the structure that conducting rod is set, cable is directly set in junction block, when use, the two ends of cable are connected with the terminal of electric equipment respectively, convenient and swift, difficult drop-off, has ensured the reliability being electrically connected, on cable, zinc-plated can preventing infiltrated steam between multiply heart yearn from cable, ensured explosion insulation performance.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the schematic diagram of insulating barrier in Fig. 1;
Fig. 4 is the assembling schematic diagram of cable and insulating barrier in Fig. 1.
Embodiment
As shown in Figure 1, mine explosion-suppression multicore binding post provided by the invention comprises the junction block 1 and set casing 2 of threaded engagement; Shown in Fig. 2 and Fig. 3, the interior level of junction block 1 is provided with insulating barrier 4, and the plate face of insulating barrier 4 is provided with one group of through hole 9; Shown in Fig. 4, in through hole 9, be respectively equipped with the cable 3 that stretches out junction block 1 top and bottom, when practical application, the quantity of cable can as many as 30 cores, greatly reduce the quantity of binding post, alleviate the volume and weight of flameproof enclosure, insulating barrier is removed in the position that every cable 3 is positioned at insulation board through hole 9, and the cable segment periphery of removing insulating barrier is coated with scolding tin 6; In junction block 1 cavity between described cable 3 and insulating barrier 4, be filled with epoxy resin 5; Junction block 1 bottom is provided with rubber end socket 7; The shell of described set casing 2 is provided with fixing hole, and lock-screw 8 is fixedly connected with set casing 2 by fixing hole, and is pressed on junction block 1.
When use, first junction block 1 is separated with set casing 2, and then junction block 1 is sleeved in the installing hole between Flameproof box and intrinsic safety case, afterwards set casing 2 threaded engagement are fixedly connected with junction block 1, this binding post and Flameproof box and intrinsic safety case are fixed, tighten lock-screw 8, make locking between junction block 1 and set casing 2, prevent the slip between set casing 2 and junction block 1; Then connect respectively the electric equipment in Flameproof box and intrinsic safety case by cable 3, realize electrical connection, given up the structure of conventional conductive bar, convenient and swift, difficult drop-off, has ensured the reliability being electrically connected; Epoxy resin 5 in junction block 1 will be isolated between Flameproof box and intrinsic safety case effectively, in the time that the cable of one end damages, between the multiply heart yearn in cable, can infiltrate steam, due to the effect of scolding tin 6, can isolate steam, prevent that steam from sneaking into, ensure explosion insulation performance; Rubber end socket 7 has increased insulation effect, guarantees safety.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction; Any those of ordinary skill in the art, do not departing from technical solution of the present invention scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible variations and modification to technical solution of the present invention, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, be equal to replacements, equivalence change and modify, all still belong to technical solution of the present invention protect scope in.
