Description
Technical field
The utility model is related to a kind of transformer conducting wire interconnection technique more particularly to a kind of transformer conducting bar special screw threads
Casing.
Background technology
Transformer is the main equipment in electric system, has very important function；Transformer wire clamp is connection transformer
The main devices of conducting rod and conducting wire；The prior art is when connecting transformer wire clamp and conducting rod, generally on transformer wire clamp
Hole is threaded to form conducting rod mounting hole, conducting rod is threadedly coupled with conducting rod mounting hole；
Since the size of different size transformer its conducting rod is different, to meet installation requirement, it is only each ruler
The all independent custom transformer wire clamp of very little conducting rod, this transformer wire clamp do not have versatility, and producer needs according to different rulers
The transformer wire clamp of very little conducting rod production plurality of specifications, causes product category complicated, customization cost is higher；In addition, installing
When, since the screw thread in conducting rod mounting hole is formed directly on transformer wire clamp, when being connect with conducting rod, need whole turn
Transformer wire clamp can make transformer wire clamp that can not rotate if transformer phase spacing is smaller (i.e. gap is smaller between conducting rod),
The case where causing not installing.
To solve foregoing problems, a kind of settling mode in the prior art is the conducting rod mounting hole on transformer wire clamp
Side designed openings and cancel the screw thread in conducting rod mounting hole (designed openings can make conducting rod mounting hole have certain shape
Become surplus), specifically when connection, it is first threaded casing on conducting rod, there is internal thread, conducting rod and spiral shell in threaded sleeve endoporus
Line casing tube internal hole is threadedly coupled, and threaded sleeve outer wall is smooth, and conducting rod mounting hole is directly sleeved on outside threaded sleeve, then passes through spiral shell
Bolt tightens the opening of conducting rod mounting hole side, you can realizes installation；To ensure that it is various sizes of that threaded sleeve can adapt to
Conducting rod is also required to setting opening portion on threaded sleeve, so that threaded sleeve has certain deformation surplus；To ensure locking effect
Fruit need to make the opening on threaded sleeve and the opening accurate contraposition on transformer wire clamp, otherwise be difficult to lock, but due to thread bush
Lack location structure between pipe and transformer wire clamp, when in-site installation, threaded sleeve and transformer wire clamp are received easily with respect to rotation
When opening on tight transformer wire clamp, operating personnel need with it is hand steered live transformer wire clamp, working at height is especially inconvenient, and installation is imitated
Rate is relatively low, and task difficulty is larger.
Utility model content
For the problems in background technology, the utility model proposes a kind of transformer conducting bar special screw thread casing, packets
Sleeve body is included, improvement is：Described sleeve pipe ontology is the C-shaped tubular body structure in cross section, in the endoporus of sleeve body
It is provided with screw thread；The edge of opening portion both sides is each provided with a limit raised line on sleeve body outer wall.
In use, the locating slot to match with aforementioned limit raised line need to be arranged at the opening position on transformer wire clamp, lead to
It crosses limit raised line and locating slot is formed by positioning action, the opening in the opening and threaded sleeve on transformer wire clamp can be made
Portion precisely aligns, while can also prevent transformer wire clamp and threaded sleeve from relatively rotating, and when installation, operating personnel are not required to hand steered change
Depressor wire clamp, operation are more convenient；Fine adjustments are carried out if necessary to the position to transformer wire clamp, it can direct rotary transformer
Wire clamp, threaded sleeve can also synchronize turn, can so greatly improve installation effectiveness, reduce operation difficulty.In addition, connecting
When sleeve body and conducting rod, limit raised line can also increase the impetus on sleeve body surface, improve sleeve body turn operation
Convenience.
Preferably, the groove that a cross section is U-shaped is provided on the inner hole wall of described sleeve pipe ontology；The axial direction of the groove
Parallel with the axial direction of sleeve body, the both ends of groove axial direction are connected to two end faces of sleeve body respectively；The position of the groove
It sets opposite with the opening portion.After groove, the thickness of corresponding position in sleeve body can be made to reduce, further increased
The deformation surplus of big sleeve body, is easily installed and locks.
Preferably, described sleeve pipe body end is provided with chamfering.After chamfering, sleeve body can be inserted more smoothly
Enter in conducting rod mounting hole.
The advantageous effects of the utility model are：Propose a kind of transformer conducting bar special screw thread casing, the screw thread
Casing can greatly facilitate installation operation.
Description of the drawings
The dimensional structure diagram of Fig. 1, the utility model；
The end structure illustration of Fig. 2, the utility model；
Fig. 3, transformer wire clamp dimensional structure diagram；
Fig. 4, transformer wire clamp top view；
Title in figure corresponding to each label is respectively：Sleeve body 1, opening portion 1-1, limit raised line 1-2, groove 1-
3, the conducting rod mounting hole 2 on transformer wire clamp, with the matched locating slot 2-1 of limit raised line, for installation locking bolt
Bolt hole 2-2.
Specific implementation mode
A kind of transformer conducting bar special screw thread casing, including sleeve body 1, improvement are：Described sleeve pipe ontology 1 is
The C-shaped tubular body structure in cross section is provided with screw thread in the endoporus of sleeve body 1；Opening portion 1-1 on 1 outer wall of sleeve body
The edge of both sides is each provided with a limit raised line 1-2.
Further, the groove 1-3 that a cross section is U-shaped is provided on the inner hole wall of described sleeve pipe ontology 1；The groove
The axial direction of 1-3 is parallel with the axial direction of sleeve body 1, and the both ends of groove 1-3 axial directions connect with two end faces of sleeve body 1 respectively
It is logical；The position of the groove 1-3 is opposite with the opening portion 1-1.
Further, 1 end set of described sleeve pipe ontology has chamfering.
Referring to Fig. 3,4, in use, first sleeve body 1 is threadedly coupled with the conducting rod on transformer, then by transformer
Wire clamp is sleeved on outside sleeve body 1, and due to limiting the positioning action of raised line 1-2 and locating slot 2-1, sleeve body 1 is inserted in conducting rod
When mounting hole, the opening portion 1-1 in sleeve body 1 is just targeted by with the opening on transformer wire clamp naturally；Subsequently by conducting wire with
When transformer wire clamp connects, fine adjustments if desired are carried out to the direction of transformer wire clamp, can direct turn transformer wire clamp, spiral shell
Line casing can also synchronize turn, very convenient, after regulating, the bolt of transformer wire clamp opening is tightened, transformation can be made
Device wire clamp clamps sleeve body 1.
Based on the prior art it is found that described sleeve pipe ontology 1 should use high intensity, non magnetic and high conductivity metal material
It makes, meanwhile, should also protective coating be set on 1 surface of sleeve body.
After the utility model, since two limit raised line 1-2 are symmetrically dispersed in the opening portion both sides 1-1, thread bush
Installation direction problem is not present when pipe is installed, the arbitrary end of threaded sleeve faces upward or downward the opening that can make on transformer wire clamp
It is aligned with opening portion 1-1, installation operation is very convenient.
