After the high-voltage cable terminal connector 3 is manufactured, the high-voltage cable terminal connector 3 and the conductor 2 of the A, B and C phases need to be connected naturally and reliably without forced external force.
As shown in fig. 2, the conductor 2 is fixed to a support insulator 6, the support insulator 6 is fixed to the inner wall of the high-voltage cable chamber 1, and the conductor 2 is securely connected to the high-voltage cable terminal 3 of the high-voltage cable 5 by a fixing bolt 7 and a nut 4. That is, one end of the fixing bolt 7 passes through the holes of the conductor 2 and the high-voltage cable terminal connector 3 in sequence and is fastened and connected through the nut 4.
But because the high tension cable room space is narrow and small, and the high tension cable reservation size holds inaccurately, and the high tension cable cross-section is great, difficult installation, and force the installation can make the high tension cable atress great, consequently, present structure, when conductor 2 of A, B, C three-phase is connected rather than the high tension cable terminal joint 3 that corresponds separately, can make the high tension cable atress great, unable reliable connection naturally.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in a narrow and small closed space, how to enable the installation and connection of the high-voltage cable terminal connector and ensure the reliable operation of equipment.
In order to solve the technical problem, the technical scheme of the utility model is to provide a high-voltage cable closed space installation connecting structure, which comprises a supporting insulator fixed on the inner wall of a high-voltage cable chamber, and a conductor fixed on the supporting insulator, and is characterized in that the conductor is provided with a connecting strip capable of moving along the length direction of the conductor; when the connecting strip is moved to a desired position on the conductor, one end of the connecting strip and one end of the conductor are fastened together by a fastener.
Preferably, the conductor and the connecting strip are both provided with a plurality of connecting holes, and the connecting holes on the conductor correspond to the connecting holes on the connecting strip in position.
Preferably, the fastener is a fixing bolt and a nut, and one end of the fixing bolt sequentially penetrates through the connecting holes in the conductor and the connecting strip and is fastened and connected through the nut.
Preferably, the size and the dimension of the connecting holes on the conductor and the connecting strip are the same as those of the holes on the high-voltage cable joint.
Preferably, the conductor and the connecting strip are made of the same material and have the same width.
Preferably, the length of the connecting strip is less than 30cm.
The utility model discloses a structure installs vertically movable's connecting strip additional in high tension cable is indoor, combines high tension cable terminal to connect and fixes the installation distance at the indoor conductor of high tension cable, adjusts the position of connecting strip for high tension cable is reliable with being connected of conductor, and high tension cable terminal connects and does not receive to move under the force external force condition simultaneously.
The utility model has the advantages of simple structure, use convenient operation, safe and reliable, the indoor high tension cable's of all kinds of high tension cable erection joint of being convenient for can satisfy the requirement of safe operation. Through the utility model discloses a structure for the erection joint of high tension cable terminal joint in narrow and small airtight space, and can guarantee that the operation of equipment is reliable.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.
The utility model provides a high tension cable airtight space installation connection structure, as shown in fig. 3, fig. 4, it is fixed with conductor 2 on the support insulator 6 including fixing the support insulator 6 on 1 inner wall of high tension cable room, is equipped with connecting strip 9 on the conductor 2, and connecting strip 9 can remove along conductor 2's length direction. When the connecting bar 9 is adjusted to a desired position on the conductor 2, one end of the connecting bar 9 and one end of the conductor 2 are fastened together by a fastener.
In this embodiment, the conductor 2 and the connecting bar 9 are both provided with a plurality of connecting holes 8, and the connecting holes 8 on the conductor 2 correspond to the connecting holes 8 on the connecting bar 9 in position. The fasteners are fixing bolts 7 and nuts 4, one ends of the fixing bolts 7 sequentially penetrate through connecting holes 8 in the conductors 2 and the connecting strips 9 and are tightly connected through the nuts 4.
The sizes of the connecting holes 8 on the conductor 2 and the connecting strip 9 and the holes on the high-voltage cable joint 3 are the same.
