Background technology

In the connection of power equipment, a kind of situation is to need transformer pile head and conductor cable being attached, this Kind situation, which is typically necessary, uses transformer pile head Wiring device.The basic structure of Wiring device is to include in the prior art Transformer pile head coupling part and wire interconnecting piece point, transformer pile head coupling part is connect with transformer pile head, conducting wire connection Part is connect with conductor cable, to realize the electric connection of transformer pile head and conductor cable.In order to protect transformer pile head Be not worn destruction during the connection process, connects again with Wiring device after a connecting cylinder can be generally worn outside transformer pile head It connects.But in order to ensure the close connection of connecting cylinder and transformer pile head coupling part, connecting cylinder and transformer pile head interconnecting piece Divide and be typically designed as being interference fitted, causes the two very laborious in assembling, increase working strength, reduce work effect Rate.

Utility model content

The purpose of the utility model is to overcome shortcomings and deficiencies in the prior art, a kind of for transformer pile crown is provided Termination, the Wiring device can strut the connection position of transformer pile head by adding an adjusting bolt part in assembling It sets, reduces working strength, it is time saving and energy saving, it improves work efficiency.

To achieve the goals above, the utility model is realized according to following technical scheme：

A kind of termination of for transformer pile crown, includes wiring ontology, which includes transformer stake Head coupling part and wire interconnecting piece point, the transformer pile head coupling part include to be arranged symmetrically with " C " type groove The first grip block and the second grip block, the one ends of two grip blocks is fixedly connected with wire interconnecting piece point respectively, the other end Formed clearance gaps and the first grip block be provided with from its outside through the grip block and with the lock of the second grip block threaded Tight bolt part, the second grip block are provided with from its outside through the grip block and contact with the first grip block inner side end contact Adjusting bolt part.

Further, the wire interconnecting piece point includes an at least wire connection hole, each wire connection hole be provided with to One is external through internal conducting wire connection bolt is stretched into from it less, and each conducting wire, which connects bolt and the end set of conductive contact, to be had Movable conducting wire pressing plate opposite with conducting wire connection bolt itself.

Further, the conducting wire connection bolt is to determine torque bolt.

Further, the transformer pile head coupling part further includes having one to be inserted into the first grip block and the second grip block Connecting cylinder in " C " type groove, the outer wall of connecting cylinder is smooth, and inner wall forms the internal thread with transformer pile head threaded.

Compared with prior art, advantage is the utility model：

The utility model can strut the connection position of transformer pile head by adding an adjusting bolt part in assembling It sets, reduces working strength, it is time saving and energy saving, effectively increase working efficiency；And be capable of effective protection conducting wire safety and Reliability.

In order to be able to apparent understanding the utility model illustrates the specific reality of the utility model below with reference to description of the drawings Apply mode.

Description of the drawings

Fig. 1 is one of structural schematic diagram of the utility model.

Fig. 2 is the second structural representation of the utility model.

Fig. 3 is the positive structure schematic of conducting wire connection bolt in Fig. 1.

Fig. 4 is the using state structure diagram of the utility model.

Specific implementation mode

As shown in Figures 1 to 3, the termination of for transformer pile crown described in the utility model includes wiring ontology, should Wiring ontology includes transformer pile head coupling part 1 and wire interconnecting piece point 2.

Above-mentioned transformer pile head coupling part 1 includes 11 He of the first grip block with " C " type groove being arranged symmetrically The one end of second grip block 12, two grip blocks 11,12 is fixedly connected with wire interconnecting piece point 2 respectively, between the other end is formed Gap notch and the first grip block 11 be provided with from its outside through the grip block and with the locking screw of the second grip block threaded Spigot 13, the second grip block 12 are provided with from its outside through the grip block and contact with the first grip block inner side end contact Adjusting bolt part 14.

Further, the transformer pile head coupling part 1 further includes having one to be inserted into the first grip block and the second grip block " C " type groove in connecting cylinder 13, the outer wall of connecting cylinder 13 is smooth, and inner wall is formed and the interior spiral shell of transformer pile head threaded Line.

Above-mentioned wire interconnecting piece point 2 includes there are two wire connection hole 21,22, and each wire connection hole 21,22 is provided with Two external through internal conducting wire connection bolt 23,24 is stretched into from it, and each conducting wire connects bolt 23,24 and conductive contact End set has movable conducting wire pressing plate opposite with conducting wire connection bolt itself 231,241.

Further, the conducting wire connection bolt 23,24 is to determine torque bolt.When determining precession during wiring of torque bolt When in place, nut portion stress can be broken, to ensure to be installed in place and will not cause the excessive pressure to conducting wire.

As shown in figure 4, the installation principle of the utility model is as described below：Connecting cylinder 13 is first screwed in transformer pile head 3 On, then by turn adjusting bolt part, the distance between the first grip block 11 and the second grip block 12 are strutted, to side Just by integral plugged " C " the type groove between grip block of transformer pile head 3 and connecting cylinder 13, reversed turn later is adjusted Bolt part discharges the jacking force between two grip blocks, later turn locking screw spigot 13 again, and two pieces of grip blocks 11,12 are locked Transformer pile head 3 and connecting cylinder 13 are held, finally inserts conductor cable 4 again, conducting wire connection bolt 23,24 is screwed, due to leading Line connect bolt end conducting wire pressing plate relatively freely activity, therefore conducting wire connect bolt turn during, conducting wire pressing plate with The position of conductor cable is relatively motionless, and when determining the precession of torque bolt in place, nut portion stress can be broken, to ensure to pacify It is attached to position and the excessive pressure to conducting wire will not be caused.

The utility model is not limited to above-mentioned specific implementation mode, if various changes or modifications to the utility model The spirit and scope of the utility model are not departed from, if these modification and variations belong to the claim of the utility model and are equal Within technical scope, then the utility model is also intended to include these modification and variations.
