Abstract

PROBLEM TO BE SOLVED: To increase the reliability of transmission, without causing transmission failure due to the accumulation of dust by installing a cover section covering a terminal of a modular jack. SOLUTION: An adaptor is connected to a modular jack and then a dust protective cover, having a twisted paired cable L1 passed through it, is mounted on the modular jack connected by the adaptor. The dust protective cover controls the rotation of levers 12d, 12e and, at the same time, covers a terminal 12f of a cable. Therefore, dust which has entered a box 13 from in a wall does not accumulate on the terminal 12f of the cable, and the reliability of transmission can be increased without causing transmission failures due to the accumulation of dust.

The dust-proof cover 14 is a substantially rectangular parallelepiped box, and the side facing the adapter 11 is opened to form a modular jack insertion port 14a. Further, the insertion opening 14a of the dustproof cover 14 is large enough to insert the rear part of the modular jack 12 with the adapter 12 attached. On another surface of the dustproof cover 14, a cable insertion hole 14b for inserting the twisted pair cable L1 is provided. In the present embodiment, the cable insertion hole 14b is provided on the surface 14c facing the modular jack insertion port 14a. Therefore, when the modular jack 12 to which the twisted pair cable L1 is connected is taken in and out of the dustproof cover 14, the direction of movement of the modular jack 12 is the same as the direction of movement of the twisted pair cable L1 in the cable insertion hole 12b. The arrangement of the cable L1 is easy.

The embedding box 13 is a substantially rectangular parallelepiped box having a front part opened, and the upper and lower ends of one side surface part 13a are respectively extended upward and downward.
3b and 13c. The mounting pieces 13b and 13c are provided with screw holes 13d and 13e, respectively. In addition, the upper surface portion 13f, the lower surface portion 13g, and the other side surface portion 13h each have an insertion hole 13 for inserting the twisted pair cable L1.
i, 13j, and 13k are provided. Also, extending pieces 13l and 13m are provided on the mounting frame side of the upper surface 5f and the lower surface 5g, respectively.
Are provided, and the extension pieces 131 and 13m are provided with a mounting frame 10.
Screw hole 13 at the position where it overlaps with screw holes 10c and 10d
n, 13o are provided.

The information outlet constructed as described above is mounted on a wall as follows.

First, screws 15a and 15b are screwed into screw holes 13d and 13e inside a wall provided with an opening in advance, and the embedding box 13 is screwed into the wall. next,
Insert the twisted pair cable L1 into the insertion holes 13i, 13j, 1
3k, is guided into the embedding box 13, and is inserted into the insertion hole 14b of the dustproof cover 14.

Next, with the levers 12d and 12e opened, the distal end of the twisted pair cable L1 already inserted through the dustproof cover 14 is inserted into the cable termination 12f of the modular jack 12, and the levers 12d and 12e are closed. As fixed.

Then, the adapter 11 is attached to the modular jack 12, and the dustproof cover 14 into which the twisted pair cable L1 has been inserted is attached to the modular jack 12 with the adapter 11 attached. Then, the dustproof cover 14 regulates the rotation of the levers 12d and 12e and covers the cable termination 12f.

The adapter 11 is attached to the mounting portion 10 of the mounting frame 10.
g, 10h. Then, the screw holes 10c and 10d of the mounting frame 10 and the screw holes 13 of the
n and 143o, and screws 16a and 16b are screwed into the screw holes 10c and 10d.
Then, the mounting frame 10 and the embedded box 13 are screwed.

Finally, the screw holes 9b, 9c and the screw holes 10a, 10b of the mounting frame 10 are overlapped to form screws 17a, 17b.
b is screwed into the screw holes 9b and 9c, and the cover plate 9 is screwed to the mounting frame 10. Then, the front portion 11a of the adapter 11 is exposed from the opening 9a of the cover plate 9,
The surfaces of the front portion 11a and the cover plate 9 are flush. Thus, the mounting is completed.

Therefore, when the information outlet is attached, the dustproof cover 14 covers the cable termination 12f, so that dust that has entered the inside of the box 13 from inside the wall does not accumulate on the cable termination 12f.

Further, by attaching the dustproof cover 14, since the rotation of the levers 12d and 12e in the direction away from the cable termination 12f is restricted, the levers 12d and 12e are erroneously opened. The twisted pair cable L1 does not fall off.

[0039]

Since the information outlet of the present invention is constructed as described above, according to the first aspect of the present invention, since the cover covers the terminal end of the modular jack, the inside of the box can be changed from the inside of the wall to the inside of the box. There is an effect that it is possible to provide an information outlet capable of improving the reliability of transmission without causing dust that has entered the terminal to accumulate on the termination portion or the like, thereby preventing transmission failure due to the volume of the dust.

According to the second aspect of the present invention, the first aspect is provided.
In addition to the effects of the invention described, the cover portion is a substantially rectangular parallelepiped box having a modular jack insertion opening with an open surface facing the modular jack, and the length of the modular jack insertion opening in the height direction is Since the length of the terminal portion of the modular jack when the second signal line was pressed against the second signal line by rotating the lever was substantially equal to the length in the height direction,
By mounting the cover part, the rotation of the lever can be regulated, and the lever is not accidentally opened and the twisted pair cable does not fall off, resulting in transmission failure and improving transmission reliability. This has the effect of providing an information outlet that can be used.

In the invention according to claim 3, claim 2
In addition to the effects of the described invention, since the cable insertion hole is provided on the surface facing the modular jack insertion port, when the modular jack to which the twisted pair cable is connected is inserted into and removed from the cover portion, the moving direction of the modular jack and Thus, the direction of movement of the twisted pair cable with respect to the cable insertion hole becomes the same direction, so that the twisted pair cable can be easily routed, so that an information outlet which can reduce the labor of the mounting operation can be provided.
