Abstract
The utility model discloses a kind of conductor attachment structure with retaining and anti-loosening function, it is related to a kind of electrical equipment.It includes junction block, pigtail splice, retaining spring and locking nut, locking nut and is threadedly coupled with pigtail splice, and retaining spring is socketed with pigtail splice, and the pigtail splice for being provided with retaining spring and locking nut is threadedly secured on junction block.The utility model can effectively avoid the loose contact phenomenon caused by loosening, and this structure member is few, cost is low, easy to operate, practical.
Description
Technical field
The present invention relates to a kind of electrical equipment, and in particular to a kind of that there is retaining to be connected with the conductor of anti-loosening function
Structure.
Background technology
Wear cable formula bushing shell for transformer lead link structure and use screw threads for fastening connected mode (such as Fig. 1) more.Such a mode is only
Locked by a locking nut, can be influenceed by electric power and other external force, it is possible to occur because of sleeve pipe in the process of running
Lock screw loose phenomenon, cause conductor loose contact, cause transformer safety hidden danger, and such thing had occurred in recent years
Therefore.
Traditional pigtail splice structure is as shown in Figure 1：Including junction block 1, pigtail splice 2 and locking nut 3, pigtail splice
2 are connected with junction block 1 by screw thread, then are fixed by locking nut 3.Sleeve pipe in the process of running, by electric power and
Other external force influence, and may result in the loosening of locking nut 3 and pigtail splice 2, cause conductor loose contact, cause transformer
Security incident.
In summary, the present invention devises a kind of conductor attachment structure with retaining and anti-loosening function.
The content of the invention
In view of the shortcomings of the prior art, the present invention seeks to be that providing one kind has retaining and anti-loosening function
Conductor attachment structure, can effectively avoid the loose contact phenomenon caused by loosening, and this structure member is few, cost is low,
It is easy to operate, practical.
To achieve these goals, the present invention is to realize by the following technical solutions：With retaining and anti-loosening work(
The conductor attachment structure of energy, including junction block, pigtail splice, retaining spring and locking nut, locking nut and pigtail splice spiral shell
Line is connected, and retaining spring is socketed with pigtail splice, and the pigtail splice for being provided with retaining spring and locking nut is threadably secured
On junction block.
Preferably, described locking nut and the bottom thread of pigtail splice spin.
Preferably, described retaining spring is socketed on pigtail splice.
The present invention makes retaining spring deformation to just arriving by the distance between adjusting lock nut and junction block contact surface
Place, reaches retaining and anti-loosening effect.
Beneficial effects of the present invention：The conductor attachment structure of the present invention is reasonable in design, can effectively avoid caused by loosening
Loose contact phenomenon, and this structure member is few, cost is low, easy to operate, practical.
Brief description of the drawings
Describe the present invention in detail with reference to the accompanying drawings and detailed description；
Fig. 1 is traditional pigtail splice structural representation of background of invention；
Fig. 2 is the conductor attachment structure schematic diagram with retaining and anti-loosening function of the present invention.
Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
Reference picture 2, present embodiment use following technical scheme：Connected with retaining with the conductor of anti-loosening function
Structure, including junction block (1), pigtail splice (2), locking nut (3) and retaining spring (4), locking nut (3) and pigtail splice
(2) it is threadedly coupled, retaining spring (4) is socketed with pigtail splice (2), is provided with the lead of retaining spring (4) and locking nut (3)
Joint (2) is threadedly secured on junction block (1).
The installation steps of the conductor attachment structure of this specific implementation：
Locking nut (3) the 1st, is screwed in the bottom of thread of pigtail splice (2)；
2nd, retaining spring (4) is enclosed on pigtail splice (2)；
3rd, the pigtail splice (2) for having installed retaining spring (4) and locking nut (3) is threadably secured to junction block
(1) on；
4th, by the distance between adjusting lock nut (3) and junction block (1) contact surface, it is deflected into retaining spring (4)
It is just right, reach retaining and anti-loosening effect.
Corresponding power is calculated by Newtonian mechanics principle in retaining spring (4) size in present embodiment structure
Square, fastened, such a structure can effectively avoid the loose contact phenomenon caused by loosening, and this structure member it is few, into
This is low, easy to operate, practical.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
