2. Description of the Related Art Conventionally, a plurality of operation terminals and control terminals are connected to a signal line by a time division multiplex connection method, and operation data generated by operating a switch in an operation terminal equipped with a switch. There is provided a remote monitoring control system in which the control data is created based on the above, and the control data is transmitted to the control terminal device to which the load is connected so that the operating state of the load corresponds to the operation of the switch. .

FIG. 38 shows a remote monitoring control system.
It is configured as shown in. That is, the central processing unit 81

Individual addresses are set in the operation terminal 82 and the control terminal 83, and the central processing unit 81 uses the addresses to operate the operation terminal 82 and the control terminal 8 respectively.
Recognize 3 individually.

The central processing unit 81 uses the signal line Ls
The transmission signal Vs having the format shown in FIGS. 39 (a) and 39 (b) is transmitted. That is, the transmission signal Vs is a start pulse ST indicating the start of signal transmission, a mode data signal MD indicating the signal mode, and an address data signal for transmitting address data for individually calling the operation terminal 82 and the control terminal 83. A time slot for receiving AD, a control data signal CD for transmitting control data for controlling the load L, a checksum data signal CS for detecting a transmission error, and a return signal from the operation terminal 82 or the control terminal 83. Is a bipolar (± 24 V) time-division multiplexed signal having a signal return period WT, and data is transmitted by pulse width modulation.

In each operation terminal 82 and each control terminal 83, when the address data transmitted by the transmission signal Vs received through the signal line Ls matches the preset address data, the transmission signal Vs The control data is taken in from and the return data is returned as a current mode signal (a signal sent by short-circuiting the signal line Ls via an appropriate low impedance) in synchronization with the signal return period WT of the transmission signal Vs.

Further, the central processing unit 81 is provided with dummy signal transmitting means and interrupt signal processing means. The dummy signal transmitting means sets the mode data signal MD to the dummy mode and sets each operation terminal 82 and control terminal 83.
A dummy transmission signal having an empty address that is not set as the address data is constantly transmitted. Further, when the interrupt signal processing means receives the interrupt signal Vi generated by any of the operation terminals 82 as shown in FIG. 39C, after detecting the operation terminal 82 that generated the interrupt signal. , The operation terminal 82 is accessed to return the reply data. That is, the dummy signal transmitting means always sends the dummy signal to the signal line Ls, and the interrupt signal Vi generated from the operation terminal 82 in accordance with the operation of the switch SW is synchronized with the start pulse signal ST of the dummy transmission signal. When detected, the central processing unit 81 sends out the transmission signal Vs in which the mode data signal MD is set to the address confirmation mode by the interrupt processing means. In the address confirmation mode, the operation terminals 82 having a part of the common address are grouped, and the transmission signal Vs is collectively applied to each group. When the mode data signal MD receives the transmission signal Vs in the address confirmation mode, the operation terminal 82 that has generated the interrupt signal Vi is synchronized with the signal return period WT of the transmission signal Vs, and the operation terminal 8 is operated.
The address data set to 2 is returned as reply data. In this way, the central processing unit 81 acquires the address of the operation terminal device 82 that has generated the interrupt signal Vi, and accesses the operation terminal device 82 using the acquired address to connect to the operation terminal device 82. The operation data corresponding to the operation state of the operated switch SW is received as reply data.

In the central processing unit 81, the operation terminal 82
Based on the operation data returned from the control data, the control data to be transmitted to the control terminal device 83 to which the load L having the corresponding relationship with the switch SW is connected is created, and the transmission signal Vs including the control data is generated. The load L is controlled by sending it to the signal line Ls and transmitting the control data to the corresponding control terminal device 83.

The operation terminal 82 can connect up to four switches SW independent of each other, and the control terminal 83 can connect up to four loads L independent of each other. It is configured. That is, the operation terminal 8 in which the same address data is set
The load number data of 2 bits is set for each of the 2 and the control terminal device 83 so that the switch SW and the load L can be identified up to a maximum of four.

It has a well-known shape in which an electric wire is inserted between the contact piece 57a and the terminal frame 56a to secure an electrical contact state, and the electric wire is provided with a tip edge of the locking piece 57b. It is designed to prevent the electric wire from coming off by being cut into it. Further, the release button 58 is formed in a shape in which push projections 58b that come into contact with the locking pieces 57b are provided on both side surfaces of the main plate 58a arranged between the pair of terminal frames 56a provided on the terminal plate 56. An operation button 58c is provided on the rear edge of 58a (the lower edge of FIG. 24). Therefore, when the operation button 58c is pressed forward, a pressing force can be exerted on the locking piece 57b via the pressing protrusion 58b, and the locking piece 57b bends away from the electric wire to easily pull out the electric wire. Can be done. The operation of this type of quick connection terminal 53 is well known.

On the rear surface of the connector body 51, as shown in FIG. 26, an electric wire insertion hole 59 corresponding to each locking spring 57 is formed.

As shown in FIG. 36, the contactor 54 has a roof-shaped contact portion 54b at one end of a main body 54a having a substantially U-shaped cross section, and a positioning portion at the other end of the main body 54a. The folded portion 54c is formed and the main body 5
It is formed in a shape in which a fixing piece 54d is cut and raised at one place of 4a. The folded-back portion 54c is formed in a shape in which a substantially triangular portion that bulges away from the side surface of the main body 54a and a portion that is substantially parallel to the side surface of the main body 54a are continuous. As shown in FIG. 29, the contactor 54 includes a main body 54a, a folded portion 54c, and a fixing piece 54d.

The contactor 54 can also be positioned by abutting against.

The contact portion 54b of the contactor 54 projects through the lead-out hole 52c formed in the connector cover 52, and is introduced into the case 1 through the connecting hole 18 of the case 1 when the connector 50 is coupled to the case 1. It contacts the conductive pattern formed on the circuit board 2. Therefore, by connecting an electric wire to be the signal line Ls to the quick-connect terminal 53 of the connector 50 and bringing the contact 54 of the connector 50 into contact with the circuit board 2, the signal line Ls, which is an external electric wire, is passed through the connector 50 to the case. It can be connected to the circuit in 1. The conductive pattern of the circuit board 2 that contacts the contactor 54 is connected to the lead plate 3. That is, the pair of left and right lead plates 3 of the case 1 are connected to the signal lines Ls, respectively.

According to the above-mentioned structure, since the back surface of the case 1 is located in front of the back surface of the mounting frame 60, when the mounting frame 60 is attached by abutting against the construction surface, the case 1
Since it is not necessary to form a hole for inserting the rear part on the construction surface, the construction work becomes easy. Moreover, if the connector 50 is connected to one case 1, the signal line Ls can be sent and wired between the cases 1 through the conductive piece 74 attached to the mounting frame 60. If only one is used, it is possible to attach a plurality of cases 1 to the construction surface. In addition, the embedded box 4 for the construction surface
The mounting frame 60 may be directly mounted without using the connector, and in that case, a hole large enough to accommodate the connector 50 may be formed on the construction surface. Construction becomes even easier.

In the above structure, the body 10 has vertical and horizontal dimensions of about three of the standardized unit size of the wiring device, so that the body 10 has a relatively large storage space even though it is thin. Since it can be formed in the case 1, a relatively large number of parts can be housed in the case 1. Further, in the above embodiment, the two cases 1 are attached to the attachment frame 60, but the attachment frame 60 is formed so that only one case 1 is attached, or three cases 1 are attached.
The mounting frame 60 may be formed so that one or more cases 1 can be attached.

As described above, according to the present invention, the case is attached to the mounting frame which is mounted so as to abut the construction surface, and the rear surface of the case is located at the same position as or at the front of the rear surface of the mounting frame. Since there is no need to form a hole to embed the rear part of the case on the construction surface, there is an advantage that it can be constructed without using an embedded box if the mounting frame is directly attached to the construction surface. . Further, since the connecting portion for detachably coupling the connector connected to the end portion of the signal line is provided on the back surface of the case, it is not necessary to provide a terminal portion for directly connecting the signal line to the case, and the case can be attached. There is an advantage that it can be formed to be thin, and moreover, by connecting the signal line to the connector, the electrical connection for the signal line can be made reliable. In short, it suffices to secure a hole in the construction surface in which the connector can be embedded, and it is not always necessary to use an embedding box, and it is possible to construct easily and when forming the construction surface. Since the signal line can be pre-wired in the construction surface, there is an advantage that the signal line can be constructed without being exposed to the outside and the appearance can be made beautiful.

Further, a pair of lead plates electrically exposed to the signal lines through the connecting portions to which the connectors are connected facing the back surface of the case are exposed on each side surface of the case, and a plurality of them are attached to the mounting frame. Since a conductive piece that can contact the lead plate exposed from the case is provided between the adjacent mounting windows, the mounting window of The signal line can be sent and wired through the lead plate and the conductive piece. As a result, even if a plurality of cases are provided, it is sufficient to provide one connector, and if the embedded box is not used, a hole having the size of one connector is formed on the construction surface. Even if the embedding box is used, it is sufficient to form a hole having the size of one embedding box on the construction surface, which is advantageous in that the construction becomes very easy.

Further, a mounting frame is formed so that it can be attached to an embedding box that is standardized for embedding type wiring equipment,
In addition, with the configuration that the decorative plate used for the embedded wiring device can be attached to the mounting frame, it becomes possible to perform the installation using the embedded box and the decorative plate that have been provided so far, which is required for the construction. It is possible to use a member for wiring equipment as a member, and it is possible to suppress an increase in manufacturing cost.
