なり、端子機能を損ねることになる。The conventional example has the following problems. (1) In the conventional example, the insertion depth of the driver is determined by the intuition of the operator, and may be too deep. However, if it is too deep, the locking spring portion of the terminal spring is plastically deformed, so that the electric wire does not come into contact with the terminal fitting and the terminal function is impaired.

A problem arises in sex.

Therefore, when electric wires having different wire diameters are inserted into the pair of spring plates, the pressure contact force of the thin electric wire is weakened by the bending of the spring plate by the adjacent thick electric wire. This is because the interference of the adjacent spring plate is because the bending of the spring plate by the thick electric wire extends to the bottom of the spring plate and causes the adjacent spring plate to bend in the same direction via the connecting portion.

Is bent by the pressing force of the electric wire 25, and is displaced from the state shown by the solid line to the state shown by the chain line.
The lock spring portion 13 and the pressing spring portion 14 connect the electric wire 25 to a terminal fitting.
7 and the terminal fitting 7 also connects the electric wire 25 to the terminal bar.
And press it. That is, the horizontally long projection 8b of the terminal fitting 7 is inserted.
The left and right electric wires 25 are pressed against the terminal spring 11.

Is provided with the rigidity reinforcing means 20, the deformation force of one lock spring portion 13 is not transmitted to the other lock spring portion 13 via the bottom portion 12. Therefore, since the pair of lock spring portions 13 does not interfere with each other, the insertion of the electric wire 25 into one of the lock spring portions 13 affects the pressing force of the other lock spring portion 13 on the electric wire. I will not receive it.

Since the rigidity is increased by the rigidity reinforcing means 8, there is no bending. Therefore, the contact pressure of the left and right electric wires 25 to the terminal fitting 7 becomes uniform, and the conduction reliability of the left and right electric wires 25 can be improved.

c acts as a guide groove when the electric wire 25 is inserted.
c is deeper on the side of the horizontally long convex portion 8b. For this reason, the groove portion facing the locking spring portion 13 is deep, and there is room in the insertion space, so that the electric wire 25 can be easily inserted. Also, groove 8
In (c), the portion of the groove on the terminal side facing the pressing spring portion 14 is shallow. Therefore, the electric wire 2
5, the pressing force acts strongly, and the conduction reliability increases. Further, the inserted electric wire 25 and the terminal fitting 7 are in contact with each other at two points, that is, the top and the end edge of the horizontally long convex portion 8b near the tip of the terminal fitting 7. Therefore, the contact force with the electric wire 25 is
The continuity is stabilized because it is concentrated at two places. In the above example, the groove 8c is an inclined groove, but it may be a parallel groove whose depth is not changed.

バネ部を押圧しても該バネ部を押し過ぎることはない。
そのため、鎖錠バネ部は弾性限界内で変形するので、塑
性変形の発生を防止できる。The present invention has been configured as described above.
It has the following remarkable effects. (1) Since the driver stopper is provided in the movement locus of the driver, even if the driver is inserted from the driver insertion hole and the locking spring is pressed, the spring is not overpressed.
Therefore, the locking spring portion is deformed within the elastic limit, so that it is possible to prevent the plastic deformation from occurring.
【0033】(2)端子金具が剛性補強手段を備えてい
るので、端子金具のたわみが無くなって均等な接触圧を
保つことができる。そのため、従来例に比べ、左右の電
線の導通信頼性を向上させることができる。(2) Since the terminal fittings are provided with the rigidity reinforcing means, the terminal fittings can be prevented from being bent and uniform contact pressure can be maintained. Therefore, the conduction reliability of the left and right electric wires can be improved as compared with the conventional example.
【0034】(3)鎖錠バネ部の折曲基部に剛性補強手
段を設けたので、一方の鎖錠バネ部の変形力が底部を介
して他の鎖錠バネ部に伝達されることはない。従って、
各鎖錠バネ部は互いに干渉することなく独自に変形する
ので、一方の鎖錠バネ部の電線による変形が他方の鎖錠
バネ部の電線への圧接力を弱めることはない。(3) Since the rigidity reinforcing means is provided at the bent base portion of the lock spring portion, the deformation force of one lock spring portion is not transmitted to the other lock spring portion via the bottom portion. . Therefore,
Since each lock spring portion deforms independently without interfering with each other, the deformation of one lock spring portion by the electric wire does not weaken the pressing force of the other lock spring portion to the electric wire.
