The distance between the central piece 15a 'and the central piece 15a' is increased as the distance between the central piece 15a 'and the central piece 15a' increases. That is, as shown in FIG.
A bent portion X in a direction facing the central piece 15a 'of 5c',
Since the distances A and B between the bent portion Y in the direction away from the central piece 15a 'and the central piece 15a' have a relationship of A <B, a large force is required to bend the pressing piece 15c '. The range of the applicable electric wire (the range of the diameter of the connectable core wire 101) has been narrowed due to the strength of the conductive material forming the lock spring 15 '. Also, since the force required to bend the pressing piece 15c 'is large, even if a core wire made of a stranded wire is inserted, the pressing wire 15c' does not bend and the core wire is separated and the stranded wire may be connected. could not.

撚り線の結線も可能となる。According to a first aspect of the present invention, in order to achieve the above object, a terminal plate and a core wire of an electric wire inserted from a side of the terminal plate are brought into contact with the terminal plate and the core wire is inverted. A lock spring for preventing the insertion in the insertion direction, wherein the lock spring is formed by bending an elastic conductive plate so that the center piece is disposed opposite to the terminal plate, and a leading edge is formed from a connection portion with the center piece. A lock piece that is inclined toward the terminal plate toward the terminal plate and whose leading edge bites into the core wire to prevent it from falling off, extends from the connection portion with the central piece toward the terminal plate, and the tip end is connected to the terminal plate toward the terminal plate. A pressing piece that elastically holds the core wire between the pressing piece and the terminal plate is formed, and the pressing piece has the narrowest space between the pressing piece and the center piece on the distal end side than the connection portion with the center piece. It is characterized by being bent to become a lock spring compared to the conventional It is possible to lengthen the size of to the tip while suppressing the size increase of the body from the connecting portion of the central piece of the pressing piece. For this reason, the force required to deflect the pressing piece is reduced, so that the range of applicable electric wires can be expanded and stranded wires can be connected.

とができる。By the way, in the switch of the present embodiment, a lighting display section 52 having a neon lamp 53 for lighting up when the one-side contact type contact section 8 is turned off to indicate the installation position of the switch is incorporated in the reversing handle 30. A neon lamp 53 is inserted into an opening 34 formed in the front of the reversing handle 30.
Is facing. An elongated hole 54 that penetrates the operation handle 38 is formed in a portion corresponding to the opening 34 of the operation handle 38. The prism 55 made of a light guide member has an elongated convex portion 56 having a rounded end which is inserted into the hole 54 and whose tip projects from the front surface of the operation handle 38. Is fixed to the operation handle 38 with the projection 56 inserted therein. Thus, when the operation handle 38 is attached to the reversing handle 30, the incident surface 57 of the prism 55 is arranged to face the neon lamp 53. Further, since the tip of the convex portion 56 of the prism 55 protrudes from the front surface of the operation handle 38, the position of the operation handle 38 pressed when the contact portion 8 is turned on by the convex portion 56 can be easily determined. it can.

不良を防ぐことができる。By the way, in the conventional example, FIG.
As shown in FIG. 7, since the distance between the leading edge of the locking piece 15b 'of the lock spring 15' and the leading end of the pressing piece 15c 'is large, the leading edge of the locking piece 15b' first passes when the core wire 101 is inserted. Then, there is a resistance when the pressing piece 15c 'is bent by contacting the tip of the pressing piece 15c'. For this reason, as shown in FIG. 4A, two peaks occur in the insertion force of the core wire 101, and the insertion feeling of the core wire 101 when the electric wire 100 is connected is not good. On the other hand, in the present embodiment, since the distal end of the pressing piece 15c that comes into contact with the core wire 101 is arranged near the distal end edge of the locking piece 15b, the contact piece 1 between the locking piece 15b and the terminal plates 11, 12 is provided.
3c and 14c, the core wire 101 is inserted,
As shown in (b), the distal end portion of the lock piece 15b bent away from the contact pieces 13c and 14c comes into contact with the distal end portion of the pressing piece 15c to bend the pressing piece 15c. For this reason, as shown in FIG. 4B, only one peak occurs in the insertion force of the core wire 101, and the insertion feeling of the core wire 101 at the time of connection of the electric wire 100 is improved, so that the insertion failure of the core wire 101 can be prevented. .

なるという利点がある。When the distal end of the pressing piece 15c that comes into contact with the core wire 101 is disposed near the distal end edge of the lock piece 15b as described above, when the release button 18 is operated to bend the lock piece 15b. If the locking piece 15b and the pressing piece 15c interfere with each other, the release operation becomes difficult. Therefore, in the present embodiment, as shown in FIG. 5, the portion Z of the pressing piece 15c facing the locking piece 15b is curved in a direction away from the locking piece 15b. There is an advantage that the locking piece 15b can be prevented from interfering with the pressing piece 15c when the 15b is bent, and the release button 17 can be easily released.

Thus, the lock spring 15 is formed. That is, for the distance L1 between the contact pieces 13c, 14c and the contact pieces 13c, 14c in the U-shaped portions 13, 14 of the terminal plates 11, 12, the tip of the central piece 15a and the tip of the lock piece 15b in the lock spring 15 is provided. The distance L2 from the edge is narrowed (L1
> L2). In this manner, the end edge of the lock piece 15b and the terminal plate 1
By providing a gap between the first and second contact pieces 13c and 14c, there is an advantage that a core wire made of a stranded wire can be easily inserted.

There is a possibility that it cannot be stabilized. Therefore, in the present embodiment, as shown in FIG.
A plurality of Rs protruding in a direction to contact with 1 are provided. For this reason, according to the diameter of the core wire 101,
The contact position between the lock spring 15 and the pressing piece 15c changes.
