When the thin portion 17b is pressed against, only the thin portion 17b is punched out, and as shown in FIGS. 13 (A) and 13 (B), two wires can be passed. On the other hand, when the thick portion 17a is pressed, Since the thick portion 17a is also a thin fragile portion as compared with the other portion of the protective cover 4, the fragile portion 17 is entirely punched out,
As shown in FIGS. 14 (A) and 14 (B), it is configured so that four lines can be passed. Of course, the fragile part 17 is first
You may apply to an Example.

Next, the assembly and construction of the image pair wire type branching / distributor according to the first to third embodiments will be explained. The P plate block 2 is screwed to the rear surface of the body 1,
After that, the back cover 3 of the main body is attached to the body 1. Thereafter, as shown in FIG. 6, the body 1 side is screwed and fixed to a mounting surface 200 such as a wall or an electric board. Then, in the case of exposed wiring, as shown in FIG. 16, the electric wire B is arranged in the groove 12 for electric wire distribution, and each core wire b of the electric wire B is inserted into each quick-connect terminal 6 for one-touch operation. The wiring is completed. Further, in the case of the embedded wiring, FIGS.
As shown in FIG. 3, the core wires b of the electric wire B led out from the electric wire insertion hole 5b to the front side of the body 1 are inserted into the respective quick-connect terminals 6 to complete the one-touch connection.

Then, the case where the protective cover 4 is attached to the body 1 will be described. First, in the case of the first embodiment, when the protective cover 4 is covered and pressed from above the body 1, the first locking claw 106 on the body 1 side and the protective cover 4 side are lowered due to the lowering of the wall end of the protective cover 4. At the same time that the locking recess 107 is locked to each other, the second locking claw 103 on the body 1 side and the claw receiving hole 102 on the protective cover 4 side are locked to each other. As a result of providing the second locking claw 103 with the inclined surface 103, when the second locking claw 103 and the claw receiving hole 102 are locked, the second locking claw 103 is smoothly engaged with the claw receiving hole 102. Be stopped. As a result, the protective cover 4 is capped on the body 1, and the protective cover 4 is attached to the body 1.

On the other hand, when removing the protective cover 4 from the body 1, the handle 101 on the side of the protective cover 4 may be gripped by hand and pulled in the direction in which it is detached from the body 1 (direction X in FIG. 6). At that time, the second locking claw 103 and the claw receiving hole 102 are unlocked while the first locking claw 106 and the locking recess 107 are still locked, and the first locking claw 106 and the locking are received. The handle portion 101 side of the protective cover 4 rotates and is released from the body 1 with the engagement with the concave portion 107 as a fulcrum, and further pulling of the handle portion 101 engages with the first engagement claw 106 that has been engaged. The engagement with the recess 107 is released, and thus the protective cover 4 can be easily removed from the body 1.

As described above, the engagement between the second engaging claw 103 and the pawl receiving hole 102 is released before the engagement between the first engaging claw 106 and the engaging recess 107. The reason is that the locking strength between the second locking claw 103 and the claw receiving hole 102, the first locking claw 106 and the locking recess 107 are set.
This is because the latter is stronger than the latter. That is, as shown in FIG. 3, the second locking claw 103 has an inclined surface 103 on both sides of the locking surface with the claw receiving hole 102.
Since a and 103b are provided, when the protective cover 4 is removed from the body 1, the second locking claw 103 and the claw receiving hole 10 are provided.
Although the engagement with 2 can be easily released, the first engagement claw 10
3 has a slanting surface 107a only on one of its locking surfaces, so that the protective cover 4 can be smoothly attached to the body 1, but the other one surface 103b is not a slanting surface, and is substantially on the surface of the body 1. Since it is a vertical hooking surface 103b,
When removing the protective cover 4 from the body 1, the first locking claw 1
This is because the surface 103b of 06 is hooked on the locking recess 107. With this configuration, it is possible to easily remove the protective cover 4 from the body 1 with the branching / distributor A attached to the attachment surface 200 as shown in FIG. It is labor saving.

When the work of detaching the protective cover 4 from the body 1 is performed at hand, the holding surfaces 105 of the body 1 are held by the fingers of one hand to support the body 1 as shown in FIG. While pulling the grip portion 101 in the direction of the arrow (the direction in which the protective cover 4 is detached from the body 1) with the other hand, the work of detaching the protective cover 4 from the body 1 can be facilitated. Alternatively, as shown in FIG.
The protective cover 4 and the body 1 can be separated from each other by inserting a tool 201 such as a flat-blade screwdriver into 4 and prying it open.

Further, in the case of the third embodiment, in order to mount the protective cover 4 on the body 1, the protective cover 4 is covered from above the body 1 and is strongly pressed.
The protrusion 13 of the body 1 is pushed inward against the elastic force by the lowering of the wall end of the body 1, and is elastically locked to the inner wall of the protective cover 4 as a result. 1, the protective cover 4 is attached to the body 1.
On the other hand, when detaching the protective cover 4 from the body 1, when the detaching protrusion 14 is pushed inward, the protrusion 13 integrally provided with the detaching protrusion 14 has its elastic force. As a result of being pushed in slightly against the inner wall of the protective cover 4, the protrusion 13 is disengaged from the inner wall of the protective cover 4, and the protective cover 4 can be smoothly removed from the body 1 (see FIG. 18).

As described above, in the video pair wire type branching / distributing device according to each of the above-mentioned embodiments, the P plate block 2 having the attenuation circuit mounted is fixedly attached not to the inside of the protective cover 4 but to the body 1 side. Body 1 side and protective cover 4
It is not necessary to connect to the side with a lead wire, etc., and the workability is significantly improved compared to the conventional one. In addition, since the P board block 2 on which the damping circuit is mounted is provided on the body 1 side and the quick-connect terminals 6 are arranged in a row on the P board block 2, the wiring can be performed with one touch. Work can be done efficiently. In addition, the electric wire can be led out of the body 1 through the electric wire insertion hole 5b, and the core wire of the electric wire B can be easily inserted into the quick-connect terminals 6 arranged on both sides in the lateral direction of the body 1 by a one-touch type insertion. Since it can be connected to, the workability in the case of embedded wiring is improved.

Furthermore, by selecting the use of the wire insertion hole 5b or the grooves 12 and 12a for wire distribution, efficient connection to the quick-connect terminal 6 can be achieved regardless of whether it is an exposed wiring or an embedded wiring. It is possible. Also, the grooves 12 and 12 for wire distribution
By providing a, the electric wire B can be stably arranged and fixed in the grooves 12 and 12a, and particularly when the electric wire B is formed with a downward slope in the longitudinal direction of the body 1 as in the groove 12a. Supportability for the electric wire B arranged and fixed in the groove 12a is improved, the electric wire B can be held without being displaced, and there is no possibility that unnecessary stress is applied to the electric wire B to cause defective connection. It is possible to suppress the floating of the electric wire B from the mounting surface 200 during the exposed wiring.

Further, since the fragile portion 17 of the protective cover 4 is provided, it can be applied regardless of whether it is punched or not, regardless of whether it is a two-passage line or a four-passage line. It has the effect of dramatically improving. In addition, since the body 1 and the protective cover 4 can be attached and detached with one touch,
There is also an effect that the workability as a whole and the inspection work after the work can be smoothly performed.

The protective cover 4 can be easily removed from the body 1 by pulling the handle 101. Therefore, the work of detaching the protective cover 4 from the body 1 can be easily performed by hand or with the branching / distributor A still attached to the mounting surface, and labor can be saved during construction and maintenance. In addition, the inclined surface 10 is attached to the second locking claw 103.
Since 3a is provided, the work of locking the second locking claw and the claw receiving portion 102 can be easily performed with a small external force, and the inclined surface 103b is also provided, so that the second locking claw and the claw receiving portion are similarly provided. The work of detaching from 102 can be easily performed with a small external force. Therefore, the work of detaching the protective cover 4 from the body 1 or the work of mounting the body 1 can be easily performed with a small amount of force, and labor can be saved during construction and maintenance. Further, the holding surface 1 of the body 1
The protective cover 4 and the body 1 can be detached by pulling the grip portion 101 with the other hand while sandwiching 05 and 105 with the fingers of one hand to support the body 1. Therefore, when the work of separating the protective cover 4 and the body 1 is performed at hand, the hand supporting the body 1 is unlikely to slip off the body 1 and the separation work is facilitated.

Further, in order to prevent the fingers from slipping from the holding surfaces 105, 105, the holding surfaces 105, 105 are used in the above embodiment.
Non-slip ribs 109, 109 are provided on the surface of 105. In this case, when the detaching work between the protective cover 4 and the body 1 is performed at hand, the fingers of the hand supporting the body 1 are caught by the anti-slip ribs 109, 109 and are not particularly slipped off, so that the detaching work is facilitated.
