Description
The utility model belongs to the mining cable annex, mainly as being connected the common name cable connector between cable and cable and high-voltage switch gear.
At present domestic used such cable connector (as Xuzhou explosion-proof electric apparatus factory, Wafangdian explosion-proof electric apparatus factory co-design product) is by assembling symmetric component in the enclosure: inserted link (for self left-right symmetric), socket, insulating part, sealing ring, interior ground connection connection and connecting bolt, external ground bolt are formed.Shell comprises symmetrical mesochite, wire connection cavity, line ball chamber, platen totally eight joints.
Insulating part is cylindrical, and upward uniform six holes are identical.Chain-wales rank with the hole equal length are all arranged in the hole of lead-in cable side, cable master core and socket connection part branch can't wrappedly be increased around insulation, electrically improve and be restricted, its power frequency, impulse withstand voltage can only satisfy in the benchmark insulation level of 3～500Kv power transmission and transforming equipment, level is hanged down one grade requirement (as the 6Kv level, the specified 20kv of industrial frequency withstand voltage in short-term, the withstand voltage 40kv of specified lightning impulse), and weight is heavier.
Insulating part leans against in the screws that are mutually 120 degree on the housing and is screwed into screw and comes the adjusting center, the location.Regulate range estimation by rule of thumb, be difficult to make the insulating part position consistency in the shell of the left and right sides, may make inserted link crooked, produce internal stress, insulating part is damaged.And the some that is screwed into screw is stretched out outside the housing, and when being subjected to external force collision, insulating part has the damage possibility.
The some that interior ground connection connects with cable earth shield line is connected with bolt with the band screw metal derby that is welded in the wire connection cavity inwall.Another mode that partly links to each other with earthy inserted link is finished.Need for installing, cable connector must have wire connection cavity, line ball chamber simultaneously, and the housing joint number is many, and product weight increases, and installs inconvenient.
In use, connector often needs dismounting because of using, and inserted link, socket need plug and unplug repeatedly.Socket is easy to damage than inserted link, and the socket other end is connected with cable, installs and removes, it is very inconvenient to keep in repair, change.
For overcoming above-mentioned weak point, improve product electric durability energy, alleviate product weight, make product mounting or dismounting, maintenance, easy to use, a kind of new type mining flameproof high-voltage cable connector has been proposed.
The utility model principal character is:
1. insulating part is the insulating material pressed article with hole cylinder body, big conical tube, roundlet Taper Pipe and opening small column pipe composite structure.Key and round platform fan are arranged on insulating part cylinder cylindrical partly.
2. the connection of inner ground connection is little circular-arc with the middle part, and upper and lower faces is that a reverse level is overhanging with the middle part, and has the sheet metal in hole.Press in the opening roundlet column jecket of insulating part bottom with inserted link on its top, and its underpart is connected with the band screw grounded metal piece that is welded in the mesochite inwall with screw.
3. shell has saved wire connection cavity.Now include only symmetrical mesochite, line ball chamber, platen totally six joints.And in mesochite with insulating part on key and round platform shoulder corresponding section have keyway, shoulder, have the groove of depositing elastic scheibe with corresponding section, insulating part end.
4. using inserted link instead links to each other with cable.
5. cylinder inside, insulating part middle part is embedded with three and is mutually the sheet metal that 120 degree are made shielding usefulness, and wherein a slice links to each other with the grounded metal ring that is positioned at opening roundlet column jecket bottom.
Below in conjunction with embodiment the utility model is described in detail.
Fig. 1. the insulating part perspective view.
Fig. 2. new type mining flameproof high-voltage cable connector schematic diagram.
From Fig. 1 as seen, insulating part (1) is to have hole cylinder body (1-1), big conical tube (1-2-1), (1-2-2), the insulating material pressed article of roundlet Taper Pipe (1-3) and opening roundlet column jecket (1-4) combining structure.In the cylinder of middle part three staggered, uniform macropores, three apertures are arranged, be connected side with cable and stretch out three big conical tubes (12-1), two roundlet Taper Pipes (1-3) and an opening roundlet column jecket (1-4), and apart from the about 65 millimeters places of the mouth of pipe one chain-wales rank (1-5) are arranged in the big conical tube.Opposite side stretches out three big conical tubes (1-2-2), and the hole correspondence on the Guan Junyu middle part cylinder of both sides communicates.
On the cylinder cylindrical of insulating part middle part key (1-6) and round platform shoulder (1-7) are arranged, the keyway (2-1) of its position and mesochite shown in Figure 2 (2) inwall, shoulder (2-2) matches, and is added with ring washer (3) in the insulating part end, as insulating part circumferencial direction and axial location.
Cylinder inside, insulating part middle part is embedded with three and is mutually the sheet metal (1-8) that 120 degree are made shielding usefulness, and wherein a slice links to each other with the grounded metal ring (1-9) that is positioned at opening roundlet column jecket bottom.
Insulating part can form with low glass fiber reinforced unsaturated polyester plastic (BMC), polydiallyl phthalate glass fibre reinforced mould plastic (DAP) or epoxy glass fiber enhancing injection material (or pours) pressure injection of shrinking.
In Fig. 2, ground connection brace (4) is that the middle part is little circular-arc, and upper and lower faces is that axle is reverse, level is overhanging with the middle part, and has the sheet metal in hole.Its top is pressed in insulating part opening roundlet column jecket bottom and with grounded metal ring (1-9) with inserted link (5-1) and is linked to each other, and its underpart is connected with the band screw grounded metal piece (2-3) that is welded in the mesochite inwall with screw (6), forms the connection of inner ground connection.
