Description
Technical field
The utility model is related to a kind of transformer conducting wire interconnection technique more particularly to a kind of transformations with casing limit structure
Device wire clamp.
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 is caused to need production more
The transformer wire clamp of kind specification, product category is complicated, and customization cost is higher；In addition, when mounted, due in conducting rod mounting hole
Threaded hole be formed directly on transformer wire clamp, when being connect with conducting rod, whole turn transformer wire clamp is needed, if transformer
Phase spacing is smaller (i.e. gap is smaller between conducting rod), the case where making transformer wire clamp that can not rotate, cause not installing.
For foregoing problems, those skilled in the art improve transformer wire clamp：Cancel conducting rod mounting hole
Internal thread, meanwhile, in the side of conducting rod mounting hole, open region and corresponding locking hole are set；In use, first being led in transformer
One threaded sleeve is set on electric pole, threaded sleeve outer wall is smooth, internal thread is provided in endoporus, threaded sleeve by internal thread with
Conducting rod is threadedly coupled, and then again entangles threaded sleeve with conducting rod mounting hole, clamping screw is used in combination to lock open region；This
The transformer wire clamp of kind structure is suitable for various sizes of conducting rod installation needs, and the versatility of transformer wire clamp is preferable, and
When installation, turn transformer wire clamp is not had to, the requirement to installation space is relatively low；
The problem is that：In threaded sleeve scheme above-mentioned, with setting open region principle similarly, threaded sleeve
On be also equipped with corresponding opening portion, opening portion can allow threaded sleeve to have certain deformation surplus, so can also make screw thread
Casing can be suitable for various sizes of conducting rod；But when mounted, in order to ensure locking of the transformer wire clamp to threaded sleeve
Effect needs that open region and opening portion above-mentioned is made to align, and otherwise transformer wire clamp is difficult to lock threaded sleeve, due to
Lack corresponding location structure between transformer wire clamp and threaded sleeve, when specific installation, transformer wire clamp and threaded sleeve it
Between easily with respect to rotation, operating personnel need to be buttressed transformer wire clamp with hand when carrying out locking operation, operation very not side
Just, especially working at height when, difficulty is larger.
Utility model content
For the problems in background technology, the utility model proposes a kind of transformer wire clamp with casing limit structure,

Press from both sides ontology；The limiting slot is connected to open region, and two limiting slots are located at the both sides of open region.
In aforementioned schemes, the main improvement of the utility model is that limiting slot is provided in casing connection hole, with this
The threaded sleeve that utility model is used cooperatively is also required to accordingly improve, that is, needs that phase is arranged in the opening portion both sides of threaded sleeve
The positioning strip answered (for the improvement project of threaded sleeve, applicant separately declares)；When threaded sleeve and casing connection hole are inserted
When connecing, due to the positioning action of positioning strip and limiting slot, when in threaded sleeve plug-in-sleeve connecting hole, the opening on threaded sleeve
Portion is just targeted by with the open region on transformer wire clamp naturally, meanwhile, positioning strip and limiting slot can also play position-limiting action, can be with
Threaded sleeve and transformer wire clamp is avoided to relatively rotate, operating personnel are when locking open region, it is not necessary to hand steered transformer
Wire clamp, operation convenience are preferable.
Based on the prior art it is found that the other end opposite with casing connection hole on wire clip body also needs setting to be led for connecting
The conductor connecting structure of line, in order to enable wire clip body to play preferable using effect, the utility model can also with it is following
Conductor connecting structure is combined：The wire connection hole for connecting wire, conducting wire connection are provided on the wire clip body end face
Hole and casing connection hole are located at the both ends of wire clip body；It is provided at position corresponding with wire connection hole on wire clip body
The hold-down bolt hole of radial communication wire connection hole.In use, wire termination is inserted into wire connection hole, then spiral shell is being compressed
Hold-down bolt is set in keyhole, conducting wire is pushed against on the hole wall of wire connection hole by hold-down bolt.
Further to improve using effect, existing signal wire mounting hole can be also combined with the utility model, be had
Body scheme is：It is provided with signal wire mounting hole on wire clip body end face where the wire connection hole；On wire clip body with letter
The signal wire that radial communication signal wire mounting hole is provided at number corresponding position of line mounting hole compresses screw hole.In use, will letter
Number thread end is inserted into signal wire mounting hole, is then compressed in screw hole in signal wire and housing screw is arranged, and passing through housing screw will
Signal wire is pressed in signal wire mounting hole.
In order to further increase the locking stability of wire clip body, the utility model also proposed following preferred embodiment：
There are two the threaded holes, and there are two the locking holes；Two threaded holes are located at the heteropleural of open region, two locking holes point
Not Wei Yu open region heteropleural；Locking hole and threaded hole positioned at homonymy are arranged along casing connection hole axially direction is parallel to；
Two threaded holes and two locking holes correspond.Locking hole is unthreaded hole, and when specifically used, clamping screw is inserted from locking hole side
Enter, two clamping screws are reversely inserted into, and since two threaded holes are located at the heteropleural of open region, this locking mode can change
Kind distributing homogeneity of the stress on transformer wire clamp improves locking stability.
Preferably, the wire clip body is made of aluminum alloy materials.Based on common sense in the field it is found that the aluminium alloy material
Material should select high intensity, non magnetic and high conductivity aluminum alloy materials.
Preferably, the wire clip body surface is provided with protective coating.
The advantageous effects of the utility model are：Propose a kind of transformer wire clamp with casing limit structure, the change
Depressor wire clamp can effectively improve the convenience of installation operation, reduce working at height difficulty.
