Description
Technical field
The present invention relates to a kind of electrical equipments, and in particular to plug-in pigtail splice.
Background technology
In recent years in Transformer, with when junction block junction pine can occur for the pigtail splice of bushing shell for transformer
Move, fall off, poor contact the case where, to transformer safety operation cause security risk.
Such as the pigtail splice structure that Fig. 1 is traditional type, such structure makes pigtail splice 1 be connected with coupling seat 2 by screw thread,
It is fixed by locknut 6, in transformer actual motion, since the long-time of transformer shakes, may result in locknut 6
Loosening with pigtail splice 1 falls off；In addition casing needs to dismount pigtail splice 1, such structure exists when reinstalling fixed
It is possible to that pigtail splice 1 and locknut 6 can be caused to be slipped to inside transformer when operation, causes larger harm.
To solve the above-mentioned problems, a kind of novel plug-in pigtail splice or necessary is designed.
Invention content
In view of the shortcomings of the prior art, purpose of the present invention is to be to provide a kind of plug-in pigtail splice, structure
Simply, reasonable design is not easy to loosen, fall off, and contact is good, and effective guarantee equipment safety is highly practical, use easy to spread.
To achieve the goals above, the present invention is to realize by the following technical solutions：Plug-in pigtail splice, including
Pigtail splice, coupling seat, mounting flange and junction block, pigtail splice are connect by pin with mounting flange, 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 equipped with pigtail splice and mounting flange
On, the conducting rod of pigtail splice end is engaged by a plurality of electric contact piece with junction block.
Preferably, being screwed on by nut between the pigtail splice and mounting flange locks cooperation, nut is screwed in
On the shaft of pigtail splice between junction block and mounting flange, the width of nut and the width of mounting flange are consistent.
Preferably, the joint shape phase of the inner surface of the junction block and pigtail splice, mounting flange, coupling seat
Matching.
Beneficial effects of the present invention：It is effectively relieved because of matching problem caused by casing vibrations, is not easy to loosen, fall off, connect
Touch good, effective guarantee equipment safety so that transformer station high-voltage side bus is more stable.
Description of the drawings
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments；
Fig. 1 is the structural schematic diagram of background technology；
Fig. 2 is the structural schematic diagram of the present invention.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
With reference to Fig. 2, present embodiment uses following technical scheme：Plug-in pigtail splice, including pigtail splice 1,
Coupling seat 2, mounting flange 3, junction block 4 and nut 5, pigtail splice 1 are connect by pin with mounting flange 3, and mounting flange 3 is logical
It crosses 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 equipped with
It is screwed on by nut 5 in coupling seat 2, between pigtail splice 1 and mounting flange 3 and locks cooperation, the conducting rod of 1 end of pigtail splice
It is engaged by a plurality of electric contact piece and junction block 4.
It is worth noting that, the nut 5 is screwed in the shaft of the pigtail splice 1 between junction block 4 and mounting flange 3
On, the width of the width and mounting flange 3 of nut 5 is consistent.
In addition, the joint shape phase of the inner surface of the junction block 4 and pigtail splice 1, mounting flange 3, coupling seat 2
Matching, ensures the stability used.
Present embodiment assemble when, first mounting flange 3 and pigtail splice 1 are fixed by pin, then with connection
Knot seat 2 is attached fixation using bolt, ensures that mounting flange 3 is locked with pigtail splice 1 after being fixed using nut tightening, lead
Connector 1 is well contacted by a plurality of dedicated electrical contacts piece with junction block, the plug-in structural joint and tradition of above-mentioned accessory composition
Pigtail splice structure is compared, and keeps pigtail splice 1 and the electrical-contact area of junction block 4 more abundant.
Present embodiment can be effectively relieved in actual operation because of matching problem caused by casing vibrations, and will not
Generation caused by temperature change phenomena such as poor contact, having prevented conventional wire connector, existing safety is hidden in actual operation
Suffer from, and during the installation process, this structure is it is possible to prevente effectively from joint component is slipped to inside transformer, guarantee equipment safety, tool
There is wide market application prospect.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, 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.
