Abstract
The utility model discloses a kind of pigtail splices of spring touch finger structure, including coupling seat, mounting flange, pigtail splice, junction block and spring touch finger, mounting flange and coupling seat are carried out the connection that is locked by the mounting flange by the screw buckle of core aluminum pipe, it is connected between the pigtail splice and mounting flange by bayonet fittings, and pigtail splice is connected on mounting flange, the spring touch finger is mounted in junction block, the pigtail splice is also mounted in junction block, the pigtail splice and junction block are coordinated by spring touch finger compresses connection, the junction block, which is bolted on, to be equipped in the coupling seat of mounting flange and pigtail splice；The utility model is effectively alleviated because of matching problem caused by casing vibrations, and not easily to fall off, contact is good, and spring touch finger structure makes lead riser quick for installation, and contact point is more, conducts electricity very well, discharge capacity is big, effective guarantee equipment safety so that transformer station high-voltage side bus is more stable.
Description
Technical field
The utility model is related to electrical equipment technical fields, are specifically a kind of pigtail splice of spring touch finger structure.
Background technology
In recent years in Transformer, the pigtail splice of bushing shell for transformer during junction block junction with that can occur pine
It moves, come off, the situation of loose contact, security risk is caused to transformer safety operation.
Such as the pigtail splice structure that Fig. 1 is traditional type, such structure makes pigtail splice 7 be connected with junction block 6 by screw thread,
It is fixed by locknut 8, in transformer actual motion, since the long-time of transformer shakes, may result in locknut 8
Loosening with pigtail splice 7 comes off；In addition when reinstalling fixed, it is necessary to dismount pigtail splice 7, such structure exists casing
It is possible that pigtail splice 7 and locknut 8 can be caused to be slipped to inside transformer during operation, larger harm is caused.
Utility model content
The purpose of this utility model is to provide a kind of pigtail splice of spring touch finger structure, to solve the above problems.
To achieve the above object, the utility model provides following technical solution：A kind of pigtail splice of spring touch finger structure,
Including coupling seat, mounting flange, pigtail splice, junction block and spring touch finger, the mounting flange is by core by mounting flange
The connection that is locked is carried out with coupling seat, is connected between the pigtail splice and mounting flange by bayonet fittings, and lead connects
Head is connected on mounting flange, and the spring touch finger is mounted in junction block, and the pigtail splice is also mounted in junction block.
Preferably, the coupling seat, mounting flange, pigtail splice, the joint shape knot of junction block and spring touch finger
Structure matches.
Preferably, coupling seat and mounting flange lock admittedly by the mounting flange by the screw buckle of core aluminum pipe
It is fixed.
Preferably, the pigtail splice and junction block are coordinated by spring touch finger compresses connection.
It is equipped with preferably, the junction block is bolted in the coupling seat of mounting flange and pigtail splice.
Compared with prior art, the beneficial effects of the utility model are：The utility model is effectively alleviated because casing shakes institute
The matching problem brought, not easily to fall off, contact is good, and spring touch finger structure makes lead riser quick for installation, and contact point is more, leads
Good electrical property, discharge capacity is big, effective guarantee equipment safety so that transformer station high-voltage side bus is more stable.
Description of the drawings
Fig. 1 is the pigtail splice structure diagram of traditional type；
Fig. 2 is the structure diagram of the utility model.
In figure：1- coupling seats, 2- mounting flanges, 3- pigtail splices, 4- junction blocks, 5- spring touch fingers.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 2, in the utility model embodiment, a kind of pigtail splice of spring touch finger structure, including coupling seat 1,
Mounting flange 2, pigtail splice 3, junction block 4 and spring touch finger 5, mounting flange 2 is by the screw buckle of core aluminum pipe by fixation
Orchid 2 and coupling seat 1 carry out the connection that is locked, and are connected between pigtail splice 3 and mounting flange 2 by bayonet fittings, and lead
Connector 3 is connected on mounting flange 2, and spring touch finger 5 is mounted in junction block 4, and pigtail splice 3 is also mounted in junction block 4, is drawn
Wire terminal 3 and junction block 4 are coordinated by spring touch finger 5 compresses connection, and junction block 4, which is bolted on, is equipped with mounting flange
2 and pigtail splice 3 coupling seat 1 on, coupling seat 1, mounting flange 2, pigtail splice 3, junction block 4 and spring touch finger 5 connect
Place's shape matches.
The operation principle of the utility model is：It, first will be fixed by the screw buckle of core aluminum pipe by mounting flange 2 during assembling
Flange 2 and coupling seat 1 are locked, then pigtail splice 3 and mounting flange are fixed by pin, by 2 spring touch fingers 5
Lubricating grease is smeared, on request in junction block, pigtail splice 3 is injected in junction block, is connect lead by spring touch finger
First 3 and the cooperation of junction block 4 compress, finally junction block 4 is bolted on, mounting flange 2 and pigtail splice 3 is installed
In coupling seat 1, the spring touch finger structural leadthroughs connector of above-mentioned accessory composition makes pigtail splice compared with conventional wire joint structure
3 is more abundant with the electrical-contact area of junction block 4.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
