外壁や軒下に取付ける構造であり、基本的に加入者線ご
とに単独で用いる構造である。The subscriber's security device for communication uses one circuit in the subscriber line 1 circuit at the lead-in position of the subscriber line so that high voltage or large current due to lightning or contact with the distribution line does not enter the home device through the communication line.
Can be installed individually. The No. 5 subscriber protector of the Nippon Telegraph and Telephone Corporation standard, which has been widely used in the past, has a structure to be mounted on, for example, the outer wall of a house or under the eaves, and is basically a structure to be used independently for each subscriber line.
一方、近年マンションなど規模の大きい共同住宅や事務

になった。On the other hand, in recent years, a large number of large-scale apartments such as condominiums and communal buildings for offices have been constructed, and it has become more and more necessary to lead many pairs of outdoor cables into a building. In such a case, it is necessary to arrange and install a large number of subscriber protectors. In such apartments and buildings, a structure is adopted in which a corridor, a hall, and other indoor walls are hollowed out as a building structure, and a large number of communication subscriber protectors are installed in the box. Came to be.

保安器取付け作業の工数が大きくなる欠点があった。However, the conventional structure of the case for mounting the subscriber protector in this protector box is a structure (for five lines) in which at most five protector units are mounted in one case,
When there are a large number of drop-in subscriber lines, the structure is such that each of the five mounted casings is individually mounted in the protector box. Therefore, when arranging a large number of housings, it is necessary to provide a space for inserting a driver or other tools for installation work or a space for routing the wiring between the housings. It is necessary to connect with a thick wire for each case. Therefore, the number of cases that can be accommodated in one protector box, that is, the number of subscriber lines that can be accommodated in one protector box is limited, and
There was a drawback that the man-hours for attaching the protector were large.

することを目的とする。The present invention is an improvement of the present invention. It is possible to mount a small number of protector units (about 5), which can be added and added as the number of subscriber lines increases. Space for wiring and wiring, and space for ground connection can be installed at high density. An object is to provide a housing structure.

Are fitted and held together. The second housing 43B has its mounting legs 21 fixed with screws. At this time, since the female portion 23 of the first housing is fixed by the mounting leg 21 in the vicinity thereof with a screw, the two housings 43A and 43B connected to each other are not loosened. Therefore, the connected second housing 43B is fixed by one screw of the mounting leg 21. Further, the common ground terminal 3B of the first housing is connected to the common ground terminal 3C of the second housing 43B and the terminal seat 24A as described above.
Insert between and and connect with screws 25. In this way, each wiring pair 44 shown in FIG.
Connect B and 45B.

There is. Further, in the present invention, if the grounding wire common to the protector unit is provided at one place in the housing, the protector unit of each pedestal can be grounded in common, so the wiring man-hours for grounding can be small and the grounding wire can be used. There is an effect that the wiring space is not occupied in the housing.
