Description
Technical field
The present invention relates to current transformer technical field, more particularly to a kind of red copper band connection bending structure.
Background technology
Current transformer principle is according to made of electromagnetic induction principle.Current transformer is the iron core and winding by closing
Composition.Its first side winding number of turn is seldom, goes here and there in the circuit for the electric current for needing to measure, therefore it often has the whole of circuit
Electric current flows through, and secondary side winding turn ratio is more, is serially connected in measuring instrumentss and protective loop, current transformer at work,
Its secondary side circuit is to close all the time, therefore measuring instrumentss and the impedance very little of protective loop series coil, Current Mutual Inductance
The close short circuit of the working condition of device.Current transformer is that primary side high current is converted into secondary side low current to measure, secondary
Side can not open a way.
At present, using the current transformer first winding of copper belt coiling, starting needs 180 ° of turnover to outside, due to not
Easy processing shapes, and in the case of especially big in section, bending is difficult, during copper strips it is pliable not in place or crack.It is more
Material easy fracture tired out after secondary bending.And the layer insulation easily displacement between copper belt, cause interlayer to puncture.
The content of the invention
The technical problem to be solved in the present invention is：A kind of red copper band connection bending structure is provided；The red copper band connection bending
Structure can possess the mechanical strength of terminal junction, and and can prevents the situations such as bending or the expansion of side of sidewall portion, shortens connection
Length, the width at place and make first winding size as far as possible small.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
A kind of red copper band connection bending structure, is comprised at least：
The first bending section (1), the second bending section (2), the 3rd bending section (3) of string configuration；Wherein：
First bending section (1) and the 3rd bending section (3) are set parallel to each other；One end of second bending section (2) and the
One end of one bending section (1) is fixedly connected, and one end of the other end and the 3rd bending section (3) of second bending section (2) is fixed
Connection；Second bending section (2) and the first bending section (1) are perpendicular, second bending section (2) and the 3rd bending section (3)
It is perpendicular.
Preferably, the present invention additionally uses following technical scheme：
Further：First bending section (1), the second bending section (2), the 3rd bending section (3) are formed in one structure.
The present invention has the advantages and positive effects of：
By using above-mentioned technical proposal, a wire termination welding Z-type or L-type connection sheet, connection sheet 90-degree bent, make
End is folded to outside.It can be well matched with the shape of wire, can possess the mechanical strength of terminal junction, and and can is prevented
The only bending of side of sidewall portion or the situation such as expansion, shorten the length of junction, width and make first winding size as far as possible small.
Technique operation has reliability, reduces the difficulty of processing, avoids disconnecting caused by repeatedly folding,
And make once to run in long time stability state, there is good long-time contact resistance.Make product that there is good matter
Measure stability.The flexible nature of copper belt in itself, improves the buffer capacity of winding, and winding volume is small, saves space.

Embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following examples, and coordinate accompanying drawing
Describe in detail as follows：
Refer to Fig. 1 to Fig. 4, a kind of red copper band connection bending structure, including：
The first bending section 1, the second bending section 2, the 3rd bending section 3 of string configuration；Wherein：
First bending section 1 and the 3rd bending section 3 are set parallel to each other；One end of second bending section 2 and the first bending
One end of section 1 is fixedly connected, and the other end of second bending section 2 is fixedly connected with one end of the 3rd bending section 3；Described second
Bending section 2 and the first bending section 1 are perpendicular, and second bending section 2 and the 3rd bending section 3 are perpendicular.
Preferably, for the ease of processing：
First bending section 1, the second bending section 2, the 3rd bending section 3 are formed in one structure.Above-mentioned three sections by red copper
It is made.
In use, a wire termination welding Z-type or L-type connection sheet, connection sheet 90-degree bent, make end be folded to outside.
It can be well matched with the shape of wire, can possess the mechanical strength of terminal junction, and and can prevents the bending of side of sidewall portion
Or the situation such as expansion, shorten the length of junction, width and make first winding size as far as possible small.
First winding is made using copper belt, because the order end of coiling is on the inside of winding, outside need to be folded to, specifically
Turnover position refer to Fig. 3 and Fig. 4 in lower fold line 4, the position of upper fold line 5；By forming the first folding part 6 after folding
With the second folding part 7；Fold it is not in place can repeatedly do over again, can be plastically deformed or be broken at folding.And connected using Z-type
Contact pin, copper belt only need 90-degree bent, the change of mechanically and electrically performance will not occur, as shown in Figure 2.And the length in knee,
Width is small.
Embodiments of the invention are described in detail above, but the content is only presently preferred embodiments of the present invention,
It is not to be regarded as the practical range for limiting the present invention.Any changes and modifications in accordance with the scope of the present application,
All should still it belong within the patent covering scope of the present invention.
