問題がある。[Problems to be Solved by the Invention] However, in the conventional example described above, if the guide piece 4 is too long, it interferes with the partition of the body 6 as shown in FIG. In order to prevent this, the guide piece 4 is shortened to prevent the terminal 2 from being inserted.
If the guide width is reduced and the blade receiving spring 3 is eccentrically arranged in the body 6 due to poor bending accuracy or the like, the terminal 2 hits the foremost corner of the guide piece 4 as shown in FIG. There is a problem that the terminal 2 cannot be inserted smoothly.

In this case, the guide piece 5 is provided with an inclined portion 6 which becomes thinner as it goes to the foremost side of the guide piece 5 formed by digging in the front surface of the guide piece 5. Even if the length is the same, the length from the base of the guide piece 5 to the corner at the forefront can be longer than that of the guide piece 5 having the same thickness. You can now take longer.

端子接触部４間に差し込むことができるものである。As shown in FIG. 1, a blade receiving spring 3 is provided in a cavity 7 of a body 6 such as a socket. The blade receiving spring 3 is formed by bending a single metal plate, and the terminal portions of the blade receiving pieces 1 having elasticity slightly closer to the front end portions thereof are brought closer to each other to form a terminal contact portion 4. . The tip of the opposing blade receiving piece 1 beyond the terminal contact portion 4 is a guide piece 5, and the opposing guide piece 5 is designed to be wider as the distance between the two is further away from the terminal contact portion 4. The guiding pieces 5 are arranged in an inverted C shape. The front surface of the guide piece 5 is formed as an inclined portion 6 that is soaked in the thickness and becomes thinner toward the leading end of the guide piece 5. That is,
In FIG. 2, the portion indicated by the imaginary line has been cut off.
Here, in the conventional example shown in FIG.
Is the terminal guiding length length indicated by T 1, part of the length indicated by T 2 are those that have a terminal guiding length. Here T 2 are the tcosθ when the thickness of the blade receiving piece 1 and t.
On the other hand, in the present invention shown in FIG. 2, the portion indicated by T 3 is the terminal attraction length, and T 4 is smaller than the conventional example shown in FIG.
Only the terminal invitation length can be shortened. This T 4
Is (t−Δt) cos θ. Therefore, when the terminal 2 is inserted from the insertion opening 9 of the body 6, the terminal 2 is guided to the leading edge of the guide piece 5 because the terminal guide length of the guide piece 5 is long.
Thus, the terminal 2 can be smoothly guided and inserted between the terminal contact portions 4 by preventing collision.

The rear is also soaked. Thus the rear face also can be shortened portion without a guiding function of only the guide piece 5 length indicated by T 5 in FIG. 3 when stealing meat ,, As a result, as described above by steal meat front portion The length of the guide piece 5 itself can be made as short as possible while preventing the partition wall of the body 6 from interfering with each other while increasing the terminal guiding length.

止してスムーズにガイドすることができるものである。[Effects of the Invention] In the present invention, as described above, the portions slightly short of the front end portions of the opposed blade receiving pieces are brought close to each other to form a terminal contact portion. The guide pieces are arranged in an inverted C-shape so that the distance between the opposed guide pieces increases toward the side away from the terminal contact portion, and the front face of the guide piece is formed so that the front portion of the guide piece is sunk. Since the slope is made thinner toward the tip of the guide piece, the length from the base of the guide piece to the corner of the tip can be longer than that of the same guide piece. As a result, it is possible to increase the terminal guiding length on the front surface of the guide piece, to prevent the terminal from colliding with the foremost corner of the guide piece, and to smoothly guide the terminal.
