【Example】

 This embodiment comprises a holder (A), a conductive plate (B), a pair of symmetrical operating pieces (C), and two S-shaped springs (D) of the same shape.

The holder (A) is made of an insulating material, has a flat and square main body, has a pair of notches (A1) on one side, and is capable of accommodating an operating piece (C) described below inside. Is molded as. Further, a notch (A2) for leading out a terminal of the conductive plate (B) described below is provided in the center of the other side.

A conductive plate (B) is housed in the holder (A), and the conductive plate (B) is entirely made of conductive metal, and a partition (B5) is formed at the center of the holder (A). When the spring (D) described below is housed in the symmetrical position, the pair of raising pieces (B1) (B2) (B3) for positioning are raised and a terminal (on one side of the conductive plate) is raised. B4) is extended and projected.

A pair of symmetrical operating pieces (C) are prepared, a push button (C1) having a knurled head is formed, and the other side has a required angle (30 ° inside / outside) with respect to the axis of the main body. A tapered surface (C2) is formed, and an overhang (C3) is formed on one side of the main body at a position located on the end surface of the notch (A1) of the holder (A), and the overhang (C3) includes an electric wire. A guide groove (C 4) is provided, and a stopper (C 5) is projected on one side of the overhang (C), and the whole is molded with an insulating material. The operating piece (C) is a cutout of the holder (A). The symmetric operating pieces (C) are housed in (A1), the push button (C1) is exposed to the outside of the holder (A) through the notch (A1), and the upper side of the overhang (C3) is notched ( Position it at the same height as the peripheral edge of A1) and expose the end of the wire guide groove (C4) to the outside of the holder (A). Abuts the holder the inner wall, to prevent the jumping of the holder (A) outside the operating piece (C). If one side of the tapered surface (C2) is cut out (C6) on the surface leading to the wire guide groove (C4) and this surface contacts the partition (B5) of the conductive plate (B), It has a structure that constitutes a groove communicating with the groove (C4).

The linear surface (D1) of the substantially S-shaped spring (D) is raised by the raising piece (B1) of the conductive plate (B), the curved surface (D2) is raised by the raising piece (B3), and the curved surface (D3) is raised. The straight surface (D4), which is pressed against each of the pieces (B2) and extends at the required angle (inside / outside of 45 °) from the straight surface (D1), is pressed against the tapered surface (C2) of the operating piece (C). The wire holding part. In this case, two springs (D) are prepared, and one of them is used in the opposite direction. Although not shown, a lid is attached to the holder (A).

[0010]

[Action]

 Since this embodiment is constructed as described above, the terminal (B4) is used by connecting it to the telephone line modular jack type equipment by soldering, and when connecting the electric wire, the holder (A When the wire (L) is inserted through the wire guide groove (C4) that appears in the notch (A1), the central partition (B5) of the conductive plate (B) and the straight line of the spring (D) that is in pressure contact with it. It is inserted and held between the surfaces (D4) against the spring pressure.

Further, when pulling out the electric wire, when the push button (C1) is pressed, the operating piece (C) is pressed down against the spring pressure, and thus the taper in contact with the straight surface (D4) of the spring (D). The surface (C2) moves, the contact area between the two becomes small, the spring pressure applied to the electric wire is reduced, and the electric wire can be easily pulled out. These actions are similar to those of the above technique.

The pulling pieces (B1) (B2) (B3) and the central partition (B5) of the conductive piece (B) holding the spring (D) hold the spring (D) in pressure contact with each surface. In addition, when inserting the electric wire, it works more smoothly than the prior art locking projection. Further, in the case of automatic assembly, these raised pieces can be inserted horizontally into the conductive plate, and therefore, unlike the prior art of the locking projection, the assembly can be automated.

[0013]

[Effect of the device]

 Since the present invention is constructed as described above, the holder and the conductive plate for holding the spring are separately constructed, so that the assembly is easy. Especially, when the spring is assembled on the conductive plate, it is locked like the prior art. Unlike the case where the spring is held by using the protrusion, the spring is held by the pulling piece, so it is possible to insert the spring horizontally into the conductive plate. is there.
