Description
Technical field
The present invention relates to a kind of electrical equipment, and in particular to plug-in pigtail splice.
Background technology
In recent years in Transformer, the pigtail splice of bushing shell for transformer can occur pine with during junction block junction
Move, come off, the situation of loose contact, to transformer safety operation cause potential safety hazard.
If Fig. 1 is the pigtail splice structure of traditional type, this kind of structure makes pigtail splice 1 be connected with coupling seat 2 by screw thread,
Fixed by locknut 6, in transformer actual motion, as the long-time of transformer shakes, may result in locknut 6
Loosening with pigtail splice 1, come off；Sleeve pipe needs to dismount pigtail splice 1 when reinstalling fixed in addition, and this kind of structure exists
It is possible to cause pigtail splice 1 and locknut 6 to be slipped to inside transformer during operation, causes larger harm.
In order to solve the above problems, a kind of new plug-in pigtail splice or necessary is designed.
The content of the invention
For not enough present on prior art, the present invention seeks to be to provide a kind of plug-in pigtail splice, structure
Simply, it is reasonable in design, it is difficult to loosen, comes off, contact is good, and effective guarantee equipment safety is practical, it is easy to promote the use of.
To achieve these goals, the present invention is by the following technical solutions realizing：Plug-in pigtail splice, including
Pigtail splice, coupling seat, mounting flange and junction block, pigtail splice are connected with mounting flange by pin, and mounting flange passes through
Bolt is fixedly connected with coupling seat, and junction block is bolted on the above-mentioned coupling seat for being provided with pigtail splice and mounting flange
On, the conducting rod of pigtail splice end is engaged by a plurality of electric contact piece and junction block.
Preferably, spin to lock by nut between described pigtail splice and mounting flange coordinating, nut is screwed in
On the shaft of the pigtail splice between junction block and mounting flange, the width of nut is consistent with the width of mounting flange.
Preferably, the inner surface of described junction block and pigtail splice, mounting flange, the joint shape phase of coupling seat
Matching.
Beneficial effects of the present invention：Effectively alleviate and brought matching problem is shaken because of sleeve pipe, be difficult to loosen, come off, connect
Touch good, effective guarantee equipment safety so that transformer station high-voltage side bus are more stable.
Description of the drawings
With reference to the accompanying drawings and detailed description describing the present invention in detail；
Structural representations of the Fig. 1 for background technology；
Fig. 2 is the structural representation of the present invention.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect to make present invention realization is easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
With reference to Fig. 2, this specific embodiment is employed the following technical solutions：Plug-in pigtail splice, including pigtail splice 1,
Coupling seat 2, mounting flange 3, junction block 4 and nut 5, pigtail splice 1 are connected with mounting flange 3 by pin, and mounting flange 3 leads to
Cross bolt to be fixedly connected with coupling seat 2, junction block 4 is bolted on above-mentioned pigtail splice 1 and the mounting flange 3 of being provided with
In coupling seat 2, spinning to lock by nut 5 between pigtail splice 1 and mounting flange 3 coordinates, the conducting rod of 1 end of pigtail splice
It is engaged with junction block 4 by a plurality of electric contact piece.
It should be noted that described nut 5 is screwed in the shaft of the pigtail splice 1 between junction block 4 and mounting flange 3
On, width and the width of mounting flange 3 of nut 5 are consistent.
Additionally, the inner surface of described junction block 4 and pigtail splice 1, mounting flange 3, the joint shape phase of coupling seat 2
Matching, it is ensured that the stability for using.
This specific embodiment assemble when, first mounting flange 3 is fixed by pin with pigtail splice 1, then with connection
Knot seat 2 is attached fixation using bolt, ensures that mounting flange 3 is locked with pigtail splice 1, lead after fixing using nut
Joint 1 is by a plurality of dedicated electrical contacts piece and junction block good contact, the plug-in structural joint and tradition of above-mentioned accessory composition
Pigtail splice structure is compared, and makes pigtail splice 1 more abundant with the electrical-contact area of junction block 4.
This specific embodiment effectively can be alleviated because of the brought matching problem of sleeve pipe vibrations in actual motion, and will not
Because temperature change causes the generation of the phenomenons such as loose contact, conventional wire joint safety present in actual motion is prevented hidden
Suffer from, and in installation process, this structure can be prevented effectively from joint component and be slipped to inside transformer, ensure equipment safety, tool
There is wide market application foreground.
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 it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
