  Next, a procedure for attaching the intercom master A to the wall W will be described.

  First, an operation of attaching the main body module B to the wall W is performed. The main body module B is attached to the wall W by inserting and connecting a power line (not shown) connected to a commercial power source to the power terminal portion 23 of the main body module B, and a doorphone slave unit (not shown) to the signal terminal portion 25. After inserting the signal line (not shown) connected to the switch box (not shown), the rear part of the body 1 is stored in the opening on the front side of the switch box (not shown), and the box screw (not shown) is inserted. A screw hole (not shown) is provided on the front end face of the fixture fixing projection (not shown) of the switch box (not shown) through the fixing hole 3 provided on the mounting plate 2 of the vessel body 1 from the front. )). Thereby, the main body module B is fixed to the wall W after the main body module B is connected to the commercial power source (not shown) and the door phone slave unit (not shown).

  Next, a procedure for attaching the functional panel C to the main body module B and simultaneously electrically connecting the functional panel C and the main body module B will be described.

  In a state where the upper part of the functional panel C is tilted to the front side, that is, in a state where the functional panel C is inclined, each flange 4 provided on the mounting plate 2 below the main body module B is provided at the lower part of the functional panel C. The function panel C and the main body module B are coupled to each other through the hooking holes (not shown). Performing the above-described operation with the function panel C tilted makes it easy to visually check the connection point between the function panel and the body module on the rear surface of the function panel C, and between the function panel C and the wall. This is to prevent both damages due to contact and to safely perform the above-described work.

  After the functional panel C and the lower part of the main body module B are joined together, the functional panel C that has been held inclined is rotated rearward with the joint point between the hook hole (not shown) and the flange piece 4 as a fulcrum. The function panel C is brought into close contact with the main body module B. In accordance with the close contact, the rear surface of the functional panel C approaches the front surface of the main body module B, and the front end portion of the truncated conical protrusion 8 provided on the front surface of the main body module B first is the frustoconical hole 12 provided on the rear surface of the functional panel C. It enters into the circular opening 12a, and the truncated cone protrusion 8 and the truncated cone hole 12 are fitted. If the contact is further continued, the main body module side contact terminal 5 protruding to the front side from the main body module side contact terminal hole 6 provided on the front side of the main body module side and the functional panel side contact terminal hole provided on the rear surface of the functional panel C (see FIG. The function panel side contact terminals 11 projecting from the rear side to the function panel side contact terminals 11 approach, and both contact terminals are connected. By connecting the function panel side contact terminal 11 and the body module side contact terminal 5, the function panel C and the body module B can be electrically connected, and the power supply from the body module B to the function panel C and the function panel are possible. Communication between C and body module B is possible. However, at this time point, power is not yet supplied from the main module B to the function panel C. A procedure for starting power supply from the main body module B to the function panel C will be described. After the connection between the function panel side contact terminal 11 and the body module side contact terminal 5 described above, the function panel C is further brought into close contact with the body module B, and when fully contacted, the rear surface of the function panel C is provided on the upper left side of the front of the body module. The switch portion (not shown) of the power switch SW protruding from the power switch hole 7 to the front side is pressed. When the switch portion (not shown) of the power switch SW is pressed, the power switch SW shifts from the OFF state to the ON state, power is supplied to the main body module side contact terminal 5, and power is supplied to the function panel C. Will be. As a result, the electrical connection between the main body module B and the function panel C is completed, and the main body module B is connected to the hook module 4 and the hooking hole (not shown) at the lower part of the main body module B and the contact terminals are connected. The work of attaching the function panel C is completed, and the work of attaching the intercom master unit A to the wall is completed.

  By the way, in the operation of bringing the functional panel C and the main body module B into close contact with each other in the procedure for attaching the interphone master unit A to the wall W, it is assumed that the truncated cone protrusion 8 and the truncated cone hole 12 are in the opposite positions. Although the description has been given, the case where the frustoconical protrusion 8 and the frustoconical hole 12 are not in the opposing positions will be described below.

  As shown in FIG. 13, when the frustoconical protrusion 8 and the frustoconical hole 12 are at opposite positions, the main body module side contact terminal 5 and the function panel side contact terminal 11 are well connected as described above.

  When the frustoconical protrusion 8 and the frustoconical hole 12 are not in the opposite positions, the front end of the frustoconical protrusion 8 interferes with the rear surface of the functional panel C. The fact that the frustoconical protrusion 8 and the frustoconical hole 12 are not opposite each other means that the functional panel side contact terminal 11 and the main body module side contact terminal 5 are not well connected. It is necessary that the contact terminals are not connected or interfere. When the front end portion of the truncated cone protrusion 8 and the rear surface of the function panel C interfere with each other, the function panel C cannot be brought closer to the main body module B. Therefore, it is possible to prevent the functional panel side contact terminal 11 and the main body module side contact terminal 5 from interfering with each other or making a connection having a possibility of poor electrical connection.

Although the truncated cone protrusion 8 and the truncated cone hole 12 are not in the exact opposite positions, when the truncated cone protrusion 8 and the truncated cone hole 12 are close to each other, the fitting between the truncated cone protrusion 8 and the truncated cone hole 12 is performed. The fitting procedure in this case will be described. Even when the frustoconical protrusion 8 is out of the position opposite to the frustoconical hole 12, if the front end of the frustoconical protrusion 8 is located within the circular opening 12a of the frustoconical hole 12, the frustoconical protrusion The front end portion of 8 enters the truncated cone hole 12 and interferes with the inner wall surface 12 b of the truncated cone hole 12. Due to the interference between the front end portion of the truncated cone protrusion 8 and the inner wall surface 12b of the truncated cone-shaped hole 12, the functional panel C and the main body module B change their relative positions. The change in the relative position is that the front end portion of the truncated cone protrusion 8 slides on the inner wall surface 12b of the truncated cone hole 12, and the rotational symmetry axis of the truncated cone protrusion 8 substantially coincides with the rotational symmetry axis of the truncated cone hole 12. To be done. The rotational axis of symmetry between the truncated cone protrusion 8 and the truncated cone hole 12 is substantially the same as the position of the functional panel side contact terminal 11 relative to the body module side contact terminal 5 facing the body module side contact terminal 5. This means that the main body module side contact terminal 5 and the function panel side contact terminal 11 are well connected.

  Therefore, when the truncated cone protrusion 8 and the truncated cone hole 12 are fitted, the functional panel side contact terminal 11 and the main body module side contact terminal 5 are well connected, and the truncated cone protrusion 8 and the truncated cone hole 12 Is not fitted, the functional panel side contact terminal 11 and the main body module side contact terminal 5 do not come into contact with each other, and the operator can easily determine whether or not both contact terminals are located at opposing positions where a good connection is made. Can know. Conversely, by fitting the frustoconical protrusion 8 and the frustoconical hole 12, it can be easily known that both contact terminals are in the opposite positions where a good connection is made.

  Next, the shape of the truncated cone protrusion 8 and the truncated cone hole 12 and the installation location will be described.

  The truncated cone protrusion 8 is formed in a conical shape in order to correct the relative position between the functional panel C and the main body module B as described above, and the correction is performed in any of the vertical and horizontal directions. To get. Since the cone is a rotationally symmetric solid, there is no directionality with respect to the rotation axis, and even if the functional panel C and the main body module B are misaligned in any direction, up, down, left, or right, if they are conical projections The correction is possible regardless of the direction. Further, the reason why the front end portion is in the shape of a flat truncated cone is to avoid damage to each part of the functional panel due to the front end portion of the protrusion.

  The positional relationship between the truncated cone protrusion 8 and the main body module side contact terminal 5 and the height of the truncated cone protrusion 8 from the front surface of the body 1 are set as follows.

  In the operation of bringing the functional panel C into close contact with the main body module B, as described above, the frustoconical protrusion 8 and the frustoconical hole 12 are first fitted, and then the main body module side contact terminal 5 and Since connection with the function panel side contact terminal 11 is required to be performed, the height of the truncated cone protrusion 8 from the front surface of the body 1 and the installation position of the truncated cone protrusion 8 with respect to the body module side contact terminal 5 are Before the module side contact terminal 5 and the function panel side contact terminal 11 are connected, the truncated cone protrusion 8 and the truncated cone hole 12 are set to be fitted.

  Further, the inclination angle of the side surface of the truncated cone protrusion 8, that is, the side surface from the circular outline of the joint portion between the truncated cone protrusion 8 and the front surface of the body 1 toward the front end portion and the rotational symmetry axis of the truncated cone protrusion 8 are formed. The angle is such that the main body module side contact terminal 5 and the functional panel side contact terminal 11 make a good connection before the connection between the main body module side contact terminal 5 and the functional panel side contact terminal 11 is started. It is set to be placed. When the inclination angle is small, the distance at which the relative position between the function panel and the main body module can be corrected before the connection between the main body module side contact terminal 5 and the functional panel side contact terminal 11 is started is small, and the inclination angle is large. In this case, since the distance that can be corrected becomes large, when the front end of the frustoconical protrusion 8 enters the circular opening 12a of the frustoconical hole, if the distance in the front-rear direction between the contact terminals is small, the inclination angle is increased. There must be.

In this embodiment, as shown in FIGS. 1 and 2, the truncated cone protrusion 8 is provided on the front side of the vessel 1 and the truncated cone-shaped hole 12 is provided on the rear surface of the functional panel C. As shown in FIG. 6, the function panel C may have a truncated cone protrusion 8 on the rear surface and a truncated cone-shaped hole 12 on the front side of the body 1. In this case, the frustoconical hole 12 provided on the rear surface of the function panel C so that the frustoconical hole 12 provided on the front side of the container 1 does not interfere with the first circuit (not shown) housed inside the container 1. The position and depth of the hole are set.
(Embodiment 2)
As shown in FIGS. 3 and 4, the intercom base unit A according to the present embodiment is configured such that two truncated cone protrusions 8 are provided on the front side of the body 1 and two truncated cone holes 12 are provided on the rear surface of the function panel C. This is different from the information apparatus of the first embodiment.

On the front side of the body 1, a truncated cone protrusion 8 is provided at the upper left of the main body module side contact terminal hole 6, and a second truncated cone protrusion 8 is provided at the lower right, and the truncated cone protrusion 8 is fitted on the rear surface of the function panel C. second frustoconical bore 12, the frustoconical hole 12 to engagement mating with the second frustoconical protrusions 8 are provided.

The shape of truncated cone projections 8 in the present embodiment and the second frustoconical projection 8 is the same, as long as the shape satisfies the condition of the shape of a truncated cone projections 8 mentioned in embodiment 1, a frustoconical projection 8 a It is possible to make the shape of the two truncated cone protrusions 8 different.

Since the second truncated cone protrusion 8 is disposed below the truncated cone protrusion 8, in addition to the shape conditions for the shape of the truncated cone protrusion 8 described in the first embodiment, the second truncated cone protrusion 8 is formed from the front surface of the truncated cone protrusion 8 body 1.
