Abstract

Terminal fixing device of a kind of current transformer, including fixing device body, described fixing device body is provided with the binding face for contacting with terminal surfaces and for fixing the fixed structure of a terminal.Use a terminal fixing device of current transformer of the present utility model, because one time terminal is fixed together by fixed structure with binding face, ensure that a terminal will not deform in handling process, and due to fixed structure, terminal is pressed on smooth binding face after a winding welding, therefore the surface of a terminal can be corrected.Further, since groove limits each degree of freedom of a terminal, a terminal is made preferably to be protected in transport process and shape.Further, corresponding with relative position between a terminal due to the relative position between binding face, it is ensured that a terminal entirety to invariant position, thus is shaped by terminal in carrying phase.

Description

An a kind of terminal fixing device of current transformer

Technical field

This utility model relates to a kind of fixing device, is specifically related to the fixing dress of a terminal of a kind of current transformer Put.

Background technology

Current transformer, as one of important original paper that electrical equipment is supporting, the quality of itself electric property can be straight Connect and embody from inspection equipment, and presentation quality is the most out in the cold controlling.It includes a winding and magnetic core, a winding Most employing soft copper band compositions, it is welded with a terminal, and one time terminal is provided with screwed hole, it has screwed pyrite embedding Part.In current transformer production process, it is necessary first to a winding is carried to baking oven and carries out preliminary drying, then a winding is removed Carry out die-filling to die-filling position.

In whole operating process, owing to soft copper band has elasticity, due to vibrations and remove after welding and in handling process During fortune, the factor such as winding unbalance stress can cause soft copper band and terminal deformation thereon, although can enter after deformation Row is corrected, but due to the resilience force of soft copper band itself so that it is shape is easy to bounce-back, causes product at the front terminal of die-filling tool Deformation occurs, does not notes, it is easy to the situation of notch distortion under a terminal entirety occurs, causes phase para-position between a terminal Put change, thus cause a terminal normally not use.Meanwhile, after formed product, a terminal deformation causes cooperation table Face out-of-flatness, easily plays heat, longtime running after bus-bar and a termination contact during use, affect product service life, There is potential safety hazard.

Therefore, a kind of device or method it are badly in need of to solve in the transformer whole carrying operating process before production is die-filling Its terminal is easily deformed, and the most corrigibility problem after deformation.

Utility model content

The purpose of this utility model is that providing a kind of shapes in terminal carrying of transformer and operating process With the fixing device carrying out correcting after it deforms.

For achieving the above object, the technical scheme of the fixing device of a kind of current transformer of this utility model is: Yi Zhong electricity Terminal fixing device of current transformer, including fixing device body, described fixing device body is provided with for one The binding face of secondary terminal surfaces contact and for fixing the fixed structure of a terminal, described fixed structure is bolt hole, described Terminal fixing device of current transformer also includes for the bolt with the screw-internal thread fit of the inserts on a terminal, Also include the groove that a terminal of shape and current transformer matches and caves on described fixing device body, described groove Upper for constituting described binding face with the bottom surface that the one of current transformer time terminal matches, described fixing device body is tabular knot Structure.

The beneficial effects of the utility model are: use the fixing dress of a terminal of current transformer of the present utility model Put, because a terminal is fixed together by fixed structure with binding face, it is ensured that one time terminal will not become in handling process Shape, and due to fixed structure, terminal is pressed on smooth binding face after a winding welding, therefore can be to once holding The surface of son is corrected.

Further, since groove limits each degree of freedom of a terminal, a terminal is made to obtain more in transport process Good protection and sizing.

Further, corresponding with relative position between a terminal due to the relative position between binding face, it is ensured that one Terminal entirety to invariant position, thus is shaped by secondary terminal in carrying phase.

Detailed description of the invention

Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.

Embodiment 1:

The specific embodiment of terminal fixing device of current transformer of the present utility model, such as Fig. 1 to Fig. 3 institute Showing, fixing device includes that fixing device body 1, fixing device body 1 are provided with the fixed structure 4 for fixing a terminal 2, Fixing device body 1 is the insulation board 1 of platy structure in the present embodiment, and fixed structure 4 is bolt hole 4, on a terminal 2 originally Body is provided with the brass inserts 5 of the screwed hole inserting a terminal 2 itself, the screwed hole screw thread on brass inserts 5 and a terminal 2 Coordinate, and the screwed hole that is positioned on a terminal 2 of one end of the opening of brass inserts 5 with in the gap of bolt 3, on insulation board 1 Being additionally provided with shape match with terminal 2 and block the groove 6 of a terminal 2, the face that groove 6 contacts with terminal 2 is light Sliding binding face.

Terminal 2 fixing device of this utility model current transformer in use, first will complete welding operation One time terminal 2 is placed in groove 6, makes the surface of a terminal 2 fit tightly with the binding face in groove 6, and a terminal 2 Screwed hole substantially coaxial with the bolt hole 4 on insulation board 1, this groove 6 ensure that each degree of freedom of a terminal 2 all obtains Limit, make a terminal 2 preferably be protected and styling in handling process, the brass inserts that terminal is carried Being screwed in the screwed hole of a terminal, screw-in depth props up a terminal following table with the annular boss on brass inserts outer surface Till face, bolt 3 through described bolt hole 4 and is inserted the screwed hole on a terminal, and makes bolt 3 have screw thread one end to screw in In brass inserts endoporus, to tightening, now, the power formed between bolt 3 and brass inserts 5 is transmitted by brass inserts 5 To a terminal 2, while a terminal 2 is pressed on the binding face on insulation board 1, turn avoid bolt 3 and a terminal 2 directly contact and cause the damage to terminal 2 surface, simultaneously as a terminal 2 is bolted 3 and is pressed on insulation board 1 On smooth binding face, a terminal 2 after deformation can be corrected, before die-filling, bolt 3 is pulled down, take down insulation board 1, Die-filling production can be carried out.

Embodiment 2:

It is the another kind of embodiment of a terminal fixer as shown in Figure 4 and Figure 5, compared with Example 1, by insulation board The groove 6 of upper 1 saves, and uses baffle plate 8 fixed thereon instead, and the space that this baffle plate 8 is surrounded and a terminal 2 match, its Fixed form is same as in Example 1.

In other embodiments, described binding face also can be replaced the form of two bread clips, and corresponding insulation board 1 uses folder Terminal 2 is sandwiched wherein by plate form；Described screwed hole 4 also can be replaced buckle, is replaced with and card by bolt 3 accordingly The parts that snap fit is closed；The platy structure of described fixing device body also can be replaced and winding 7 entirety wrapped up the case entered Body structure.
