Here, since the insulating coating of the electric wire 2 holds the connection piece 31 or the terminal piece 32, the electric wire 2 is not detached from the connection piece 31 or the terminal piece 32 even when tension is applied to the electric wire 2.

The body 10 includes a connection base 11 having a plurality of (five in this case) guide protrusions 13 provided on the front and bottom two rows, and a base 12 extending rearward from the lower rear surface of the connection base 11. Is continuously provided. Each connecting piece 31 has a pressure contact slit 31a between each pair of adjacent guide protrusions 13.
Are held between the pair of guide protrusions 13 in a corresponding manner. Therefore, each pair of adjacent guide protrusions 1
When the electric wire is introduced between 3, the electric wire can be connected to the connection piece 31. This connection work requires a special tool such as an impact tool.

By the way, the connection base 11 is formed to be hollow,
An insertion hole (not shown) is opened in the lower portion of the rear wall so that a part of the insert 20 can be inserted. A support base 21 for holding the connection piece 31 is projectingly provided on the front surface of the insert body 20, and a terminal block 22 is formed at the rear end portion of the insert body 20 and a terminal piece 32 is projected to the upper surface side. In addition, the support base 21 and the terminal base 22
A wall plate 23 is continuously and integrally formed with the support base 21 and the terminal base 22 in a form of partitioning.

To connect the insert 20 to the body 10,
The insert 2 is inserted into the insertion hole formed in the lower portion of the rear wall of the connection base 11.
The support base 21 provided at 0 is inserted. When the insert 20 is inserted into the body 10 to a fixed position, the wall plate 2 of the insert 20 is inserted.
The front surface of 3 abuts on the rear surface of the connection base 11, and the insert body 20 is positioned with respect to the body 10. That is, the front surface of the wall plate 23 functions as a locking surface that regulates the amount of insertion of the insert 20 into the body 10. The connection piece 31 is positioned at a fixed position with respect to the guide protrusion 13 at the position where the wall plate 23 of the insert 20 contacts the rear surface of the connection base 11.

A retaining recess 12a is formed on the upper rear surface of the base 12.
When the insert 20 is opened to the fixed position with respect to the body 10, the retaining projection (not shown) protruding from the lower surface of the terminal block 22 of the inserting body 20 is inserted into the retaining recess 12a. Positional fixing of the insert body 20 with respect to the body 10 is performed by the concave and convex engagement. Here, the retaining protrusion is formed in a wedge shape so that the protrusion amount increases toward the rear side, and does not hinder the forward movement of the insertion body 20, but moves rearward after the retaining protrusion engages with the retaining recess 12a. Is forbidden. The terminal block 22 is placed on the base 12 in a state where the insert body 20 is coupled to the body 10.

By the way, this wiring member has eight conductors 3 for connecting the twisted pair cable 3 of 4 to 8 cores.
0 is held in the insert 20. That is, the wires housed in the sheath 3 a of the twisted pair cable 3 are connected to the conductor 30 as the electric wires 2. The terminal pieces 32 provided on each conductor 30 protrude from the upper surface of the terminal block 22 and are arranged in two rows in the front and rear as described above.

In order to connect the electric wire 2 to the terminal piece 32 without using a separate tool, the aligning function of holding a plurality of electric wires 2 together and the electric wire 2 are press-fitted into the press-contact slit 32a of the terminal piece 32. A holding member 40 that also has a press-fitting function and a lever 50 that applies a force in a direction that brings the holding member 40 closer to the terminal block 22 are provided. Holding member 4
0 and the lever 50 are molded products of synthetic resin and are provided in pairs.

Each lever 50 is mounted on the housing 1 by fitting a rotary shaft 51 provided on the lever 50 to a pair of bearings 24 that are continuously and integrally projected on the upper rear surface of the wall plate 23 of the insert 20. Be pivoted. That is, the lever 50 can be undulated between the position where the terminal block 22 is covered and the position where the terminal block 22 is opened. The lever 50 is formed in a shape in which the rotary shaft 51 is continuously and integrally provided between a pair of left and right arm pieces 52 projecting from one end in the longitudinal direction. The bearing 24 is open at the lower surface side. Bearing 2 for rotating shaft 51
It is designed to fit in the No.4. That is, the lever 50 is attachable to and detachable from the insert body 20.

Each holding member 40 is placed on the terminal block 22 with the lever 50 raised. When the lever 50 is tilted, the holding member 40 is pressed by the lever 50 and moves downward as the lever 50 rotates. Here, a pressing rib 47 that abuts the lever 50 is provided on the upper surface of the holding member 40. Each holding member 40 is formed in a rectangular tube shape into which the electric wire 2 is inserted, and the inside of the tube is divided into four passages having a rectangular cross section by partition walls. The electric wire 2 is inserted into each passage one by one.

By the way, when connecting the electric wire 2 to the terminal piece 32, it is necessary to move the electric wire 2 along the protruding direction of the terminal piece 32 from the terminal block 22, so that the electric wire 2 is held by the holding member 40. In order to connect the electric wire 2 to the terminal block 22 in this state, it is necessary to regulate the moving direction so that the terminal block 40 moves along the protruding direction of the terminal piece 32. Therefore, a guide protrusion 43 is provided at the center of the lower surface of the holding member 40,
The terminal block 22 provided on the insert 20 has a guide hole 25 having an opening shape that matches the cross-sectional shape of the guide protrusion 43 (see FIG. 6).
(See) is formed. Since two fixtures 20 are provided for one insert 20 here, the guide hole 25
Two are also formed.

Further, guide ribs 45 are provided so as to project from the left and right ends of the front surface of the holding member 40, and the tip end surfaces of both guide ribs 45 contact the rear surface of the wall plate 23 of the insert 20. Therefore, the forward movement of the holding member 40 is restricted by the guide rib 45 slidingly contacting the wall plate 23. In this way, the guide ribs 45 and the wall plate 23 have a function of restricting the moving direction of the holding member 40, and cooperate with the guide protrusion 43 and the guide hole 25 to move the holding member 40 in the protruding direction of the terminal piece 32. Move without rattling.

To connect the twisted pair cable 3 to the above-mentioned modular jack, four electric wires 2 are inserted into each holding member 40, and the holding member 40 is inserted into the terminal block 22 and the lever 5.
Wear between 0 and. When the lever 50 is tilted in this state,
Retaining member 40 is of the wire 2 to the terminal strip 3 2 moves downward is connected. Since the holding member 40 is restricted in the moving direction in the vertical direction as described above, the electric wire 2 is connected to the terminal piece 3
2, the terminal piece 32 is not moved by the force in the thickness direction at this time, and the terminal piece 32 is not bent.

Further, a rotary shaft 51 which is a fulcrum of the lever 50.
From the fulcrum to the rear end of the lever 50 that applies a pressing force to the lever 50, as compared with the distance from the contact point to the pressing rib 47, which is the point of application of the pressing force. Therefore, each electric wire 2 can be pushed into the press contact slit 32a with a relatively small force. Moreover, 8
Since the four electric wires 2 are divided into four when connecting them, the force required for the connection is small as compared with the case where the eight electric wires 2 are simultaneously connected to the terminal piece 32, and as a result, the lever 5 is connected.
The length of 0 can be shortened. That is, it leads to miniaturization. Furthermore, by simply applying a force to the lever 50 so that the housing and the lever 50 are sandwiched,
Since each electric wire 2 can be pushed into the press contact slit 32a, no separate tool is required, and the connection work can be performed only with the modular jack.

Since the holding member 40 has a tubular shape, when the holding member 40 moves upward from the state in which the electric wire 2 is connected to the terminal piece 32, the electric wire 2 is pushed upward together with the holding member 40 and is pushed out from the terminal piece 32. Will be pulled out.
In other words, with the electric wire 2 connected to the terminal piece 32,
If a tool such as a flat-blade screwdriver is inserted between the holding member 40 and the terminal block 22 and the holding member 40 is pushed upward, the holding member 40 moves upward and the connection state of the electric wire 2 with the terminal piece 32 is increased. Can be canceled.

The wiring member described above can be used as a relay for connecting the eight electric wires 2 to each other, but a patch panel can be constructed by using a plurality of such wiring members. To construct the patch panel, a holding frame 60 as shown in FIG. 3 is used, and a plurality of housings 1 are attached to the holding frame 60. That is, the holding frame 60 includes a front plate 62 having a plurality of opening windows 61 for exposing the front surface of the housing 1, and the positioning pieces 63 are located on the left and right side edges of each opening window 61 toward the rear.
Is projected. The positioning piece 63 regulates the forward position of the housing 1 by contacting the stepped portions 11b formed on the left and right side surfaces of the connection base 11 of the body 10. Further, a mounting piece 64 is provided so as to project rearward from a lower portion of the rear surface of the front plate 62, and a movement restricting piece 65 stands up at the rear end edge of the mounting piece 64 and engages the terminal block 22 of each housing 1. A pawl piece 66 for stopping is provided. Claw 66
An inclined surface is formed on the upper surface of the claw 66, and when a downward force is applied to the inclined surface, the claw piece 66 is bent backward.

When the housing 1 is pressed against the mounting piece 64 with the front end portion of the housing 1 inserted into the opening window 61, the terminal block 22 passes over the pawl piece 66 and is engaged by the pawl piece 66. The housing 1 is stopped and the housing 1 is held by the holding frame 60. Since a plurality of housings 1 can be attached to the holding frame 60 as shown in FIG. 4,
By connecting the connection pieces 31 provided in each housing 1 with a connection cord, it can be used as a patch panel A in which the connection relationship of the twisted pair cable 3 connected to the terminal pieces 32 can be appropriately changed.
