When C1) is exposed, it is located at the same height as the peripheral edge of the notch (BH). The wire insertion groove (C4) provided on the overhang (C3) is configured so that the rear end faces the notch (BH), and the action piece (C) is provided on one side of the body so that it does not overhang. The stopper (C5) is molded, and these are molded by an insulating material, and the operating piece (C) is provided as a pair.

The spring (S) is formed of a metal having a high spring property into a plane S shape and curved surfaces (S1) (S2) are formed in an arc shape on both sides. A straight surface (S3) having an angle of about 30 ° with the center line of the spring (S) is extension-molded at the tip of one curved surface (S2). Two springs (S) are prepared.

The odd-shaped terminals (E) and (F) are formed of a conductive metal, and one terminal (E) is substantially Y-shaped and has a centrally extended shape. This extension piece serves as a connection piece (E1), and The two pieces are the contact surfaces (E2) and (E3) of the spring (S).

The other terminal (F) has a substantially cross shape in a plan view, one end in the vertical direction is a connecting piece (F1), the other end is extended to be a monitor terminal (F2), and the horizontal surface is a spring (S). ) Contact surfaces (F3) and (F4), which are respectively formed of conductive metal.

It is arranged in pressure contact.

The cover plate (B1) on the upper surface of the holder (A) projects the monitor terminal (F2) of the terminal (F) from the hole (H1) and cuts out the push button (C1) of the operating piece (C) (BH). It should be installed more exposed.

The shape of the monitor terminal (F2) is a U-shaped side surface or an S-shaped bent shape as shown in FIGS. 10 to 13, and the surface is knurled. Prepare a hole with a circular hole in it and configure it so that it is suitable for connecting the tester.

Although the structure of the holder has been designed to be implemented as described above, it is possible to make the holder easier to assemble depending on the method of molding removal.

[0018]

[Action]

 Since the present invention is configured as described above, the method of connecting and withdrawing the electric wire is the same as the conventional method. When the electric wire (L) is inserted through the electric wire guide groove (C4), the electric wire is moved to the straight surface (S3) of the spring (S). It is pushed and pinched between the tapered surfaces (C2) that are in pressure contact, and when the push button (C1) is pushed down into the holder when pulling out the wire, the tapered surface (C2) is in pressure contact with the spring. It is pushed downward from the straight surface (S3) of (S), and the contact area between the two becomes small, so the resistance of the wire (L) decreases, and the wire can be easily pulled out. (C) is for returning to the old position by the spring pressure of the spring (S).

The relationship between the spring (S) housed in the holder (A) and the locking projections (A2) (A3) that lock the spring (S) is that in the conventional device, each locking projection is a straight line of the spring (S). Since it was located at the connection point between the curved surface (S2) on the surface (S3) side and the other curved surface (S1), that is, at the center of the spring (the base of the curved surface (S2)), insert a thick line. In this case, the spring (S) acts in a seesaw motion, and the play becomes large, so that even a thick wire can connect the wires comfortably without requiring force at the time of insertion.

As shown in the explanatory view of FIG. 14, this wire connecting device has a structure in which when the connecting pieces (E1) and (F1) are inserted and connected to the socket of the protector (T), the protector (T) is not connected. Since four plug-type single wire connection devices can be easily installed in the wiring, the tester should be connected to each monitor terminal (F2) when testing the protector. Can be done easily.

[0021]

[Effect of the device]

 Since the present invention is constructed as described above, it has the following effects. First, since the wire connecting device has a form of one part, that is, it is a plug type single item, it is economical because only the wire connecting part can be replaced without discarding the entire main body as in the past. is there.

Secondly, since the electric wire can be connected and pulled out with one touch, the work efficiency can be improved.

Thirdly, since the monitor terminals are exposed, the tester can be easily connected. The function check of the terminal block and the protector body, the line check test, the wire number symmetry check, the encounter test (Confirmation on site), etc. can be carried out easily and the work efficiency of construction can be improved.

Fourth, it can be applied to telephone wiring having a core wire of 0.4 mm to 0.9 mm.

Fifth, it can be connected to a multi, and can be connected to a plurality of mounting tools (terminal devices etc.).
