  However, in the above conventional connector connection structure, since the connection portion including the connector of the hand slave device protrudes greatly forward from the wall surface, it is easy for a patient or a nurse to accidentally catch a hand, etc. There are problems such as the connection between each other being easily disconnected and the connector being easily damaged. Further, when the hand slave unit is hooked on the plate slave unit, the connection portion of the connector becomes an obstacle, and it is difficult to hook the hand slave unit on the plate slave unit, and the hand slave unit that has been hooked easily falls off.

  Therefore, the present invention is intended to provide a connector structure in a nurse call slave unit in which the connection portion including the connector of the hand slave unit does not greatly protrude forward from the wall surface and the above-described problem does not occur. is there.

In order to achieve the above object, the invention according to claim 1 of the present invention comprises a plate slave installed on an installation surface such as a wall surface and a hand slave operated by a patient or the like. This is a connector structure in a nurse call slave unit in which the hand slave unit can be electrically connected to the plate slave connector by inserting the hand connector of the slave unit into the plate connector of the plate slave unit. In the main body case, an insertion hole for inserting the hand side connector into the main body case is provided, and the plate side connector is connected to the plate side connector of the hand side connector. It is characterized by a posture that is inclined by a predetermined angle with respect to the installation surface so that the insertion direction into the installation surface does not become a direction perpendicular to the installation surface. That.
According to the first aspect of the present invention, in the main body case, the plate-side connector is placed on the installation surface so that the insertion direction of the hand-side connector into the plate-side connector is not perpendicular to the installation surface. Since it is provided in a posture inclined by a predetermined angle, the amount of protrusion of the hand side connector from the installation surface can be reduced as compared with the conventional connector structure inserted in the direction orthogonal to the installation surface.

The invention according to claim 2 is the invention according to claim 1, wherein a hook for hooking the hand slave is provided so as to cover the front of the insertion hole, and the hook covers the front of the insertion hole. It is possible to move between the position and the position where the insertion hole is exposed.
According to invention of Claim 2, while providing the hook for hooking a hand child machine so that the front of an insertion hole may be covered, the position which covers the front of an insertion hole, and an insertion hole are exposed. Compared with the conventional connector structure in which the hooks are arranged side by side vertically and horizontally so that they do not overlap the insertion hole, the plate slave unit can be further miniaturized. Can be planned. Further, when the hand side connector is inserted into the insertion hole, the hook may be moved to expose the insertion hole, so that the workability related to connector connection is not deteriorated. Furthermore, since the hook covers the front of the insertion hole, dust or the like is unlikely to enter the main body case from the insertion hole.

The invention according to claim 3 is the plate child machine according to claim 1 or 2, wherein the first board is provided on the rear side in the main body case and the second board is provided on the front side in the main body case. A part of the plate-side connector is located between the first substrate and the second substrate.
According to the invention described in claim 3, in the plate slave device in which the first substrate is provided on the rear side in the main body case and the second substrate is provided on the front side in the main body case, the first and second substrates are provided. The plate-side connector is attached using the space between the substrates so that a part of the plate-side connector is positioned between them. Therefore, the space in the main body case can be used effectively, and the plate slave unit can be further miniaturized.

  According to the present invention, compared with the conventional connector structure that is inserted in a direction orthogonal to the installation surface, the protrusion amount of the hand side connector from the installation surface is small, so that the patient or nurse accidentally hooks the hand. This is effective in that the connector is not easily disconnected, the connector is not easily damaged, and the like. In addition, when the hand slave is hooked to the plate slave, the connector connection is less likely to get in the way, so it is easy to hook the hand slave to the plate slave and the hooked hand slave is less likely to drop off. There is also.

The machines 11 and 12 are connected by connectors as will be described later.

Here, a structure for connector-connecting the plate slave unit 11 and the hand slave unit 12 in the nurse call slave unit 2, which is a main part of the present invention, will be described with reference to FIGS.
FIG. 2 is an explanatory view showing the plate slave unit 11 from the front, and FIG. 3 is an explanatory view showing the plate slave unit 11 from the side. FIG. 4 is an explanatory view showing the plate slave unit 11 with the decorative panel 13 removed from the front, and FIG. 5 is an explanatory view showing a cross section taken along line AA in FIG. FIG. 6 is an explanatory perspective view of the plate slave unit 11 in an exploded state. FIG. 7 is an explanatory view showing the plate slave unit 11 with the hook 27 in the standing posture from the front, and FIG. 8 is an explanatory diagram showing the plate slave unit 11 with the hook 27 in the standing posture from the side. . FIG. 9 is an explanatory view showing a cross section of the plate slave unit 11 in a state where the plate side connector 20 and the hand side connector 35 are connected.

  First, the structure of the plate slave unit 11 will be described. The plate slave unit 11 includes a main body case including a storage box 14 embedded in the installation surface W, and a lid 15 assembled on the front side of the storage box 14; And a decorative panel 13 which is assembled so as to cover the peripheral edge of the lid 15. The storage box 14 is a synthetic resin box having an opening on the front surface, and a main body substrate 17 for outputting various signals to the hallway lamp 3 is provided on the rear side of the storage box 14, and the front side thereof is provided on itself. A switch board 19 mounted with a switch that is turned ON / OFF by pressing the provided button 18 is incorporated. In addition, a plate-side connector 20 for connecting the hand-side connector 35 of the hand slave unit 12 is built in the storage box 14. The plate-side connector 20 is a so-called male connector having one pin 20a, and is attached in such a posture that the pin 20a faces downward with an inclination angle of 24 ° with respect to the installation surface W. A part of the base end side of the plate-side connector 20 is located in a space sandwiched between the main body substrate 17 and the switch substrate 19 in the front-rear direction. Reference numeral 21 denotes a holding frame for attaching the plate side connector 20 or installing the switch board 19, and is fixed in the storage box 14. The holding frame 21 is provided with a guide surface 21 a for guiding the hand side connector 35 inserted into the storage box 14 to the plate side connector 20. Furthermore, 22 is a screwing plate for installing the plate slave unit 11 on the wall surface, and can be attached to a flange portion 23 provided at the front opening edge of the storage box 14.

  On the other hand, the lid 15 is a plate-like member that is assembled so as to cover the front opening of the storage box 14, and has an insertion hole 24 for inserting the hand-side connector 35 into the storage box 14 from the center to the bottom. ing. In addition, a button plate 25 is provided on the top of the lid 15, and a button 18 for stopping the blinking of the corridor lamp 3 by a pushing operation is attached so as to contact the button plate 25. Further, a bearing portion 26 is provided between the insertion hole 24 and the button plate 25, and a hook 27 for hooking the hand slave unit 12 is provided on the bearing portion 26 so as to be rotatable about the left and right direction. It has been.

  The hook 27 has a tongue piece portion 28 extending in the vertical direction, a curved piece portion 29 that protrudes forward from the lower end of the tongue piece portion 28 and then bent upward, and a shaft portion 30 at the upper end. And a frame portion 31 provided integrally with the tongue piece portion 28. The hook 27 is tilted so that the rear surface of the hook 27 comes into contact with the front surface of the lid 15 as shown in FIGS. 2 and 3, and the rear surface of the hook 27 with respect to the lid 15 as shown in FIGS. It is possible to turn between the standing postures of approximately 90 °. Further, when the hook 27 is in a tilted posture, the tongue piece portion 28 covers the front of the insertion hole 24 in front view. However, the tongue piece 28 has a bulging shape that bulges forward in an arc shape, and is formed such that the amount of bulging forward increases gradually as it goes downward, and the hook 27 is tilted. In this case, a space 32 that allows the insertion of the cable 36 of the hand-side connector 35 inserted into the insertion hole 24 is formed between the rear surface of the tongue portion 28 of the hook 27 and the front surface of the lid 15. It is like that. Note that the center of gravity of the hook 27 is in a position such that when the wall surface is installed as the installation surface W, the hook 27 is automatically tilted. Also, in the case where a projecting portion that projects forward from the wall surface is provided, when the plate slave unit 11 is installed with the top surface of the projecting portion as the installation surface W and the lid 15 facing downward, The hook 27 hangs down due to its own weight, and the rear surface of the hook 27 moves from the tilted posture to the standing posture where the rear surface of the hook 27 is approximately 60 °.

  Next, the usage mode of the plate slave unit 11 as described above will be described assuming that the plate slave unit 11 is installed with the wall surface as the installation surface W. The plate slave unit 11 has the wall surface in a posture with the lid 15 facing forward. The hook 27 is tilted as described above. Then, when connecting the hand slave unit 12, the hook 27 is lifted up to expose the insertion hole 24, the hand side connector 35 is inserted from the insertion hole 24, and connected to the plate side connector 20. . Thereafter, when the lifting of the hook 27 is released, the hook 27 turns to the tilting posture side by its own weight, and takes the tilting posture with the cable 36 accommodated in the space 32. When the hand slave unit 12 is not used, the hanger 37 provided in the hand slave unit 12 may be hooked on the hook 27 as shown in FIG. On the other hand, when the plate slave unit 11 is installed using the top surface as described above as the installation surface W, the hook 27 hangs down by its own weight and assumes a standing posture. Therefore, the hand-side connector 35 may be connected to the plate-side connector 20 without lifting the hook 27. Further, the hand slave unit 12 that is not used may be hung on the hook 27 in the standing posture as shown in FIG. The hand side connector 35 of the hand slave unit 12 is a so-called female connector having a receiving port 35a into which the pin 20a can be inserted.

According to the connector structure in the nurse call slave unit 2 having the above-described configuration, in the plate slave unit 11, the pin 20a faces the lower side with an inclination angle of 24 ° with respect to the installation surface W, and the plate side Since the connector 20 is attached, when the hand-side connector 35 is connected to the plate-side connector 20, the hand side from the installation surface W is compared with the conventional connector structure that is inserted in a direction orthogonal to the installation surface W. The protruding amount of the connector 35 can be reduced. Therefore, it is difficult for a patient or a nurse to accidentally catch a hand, the connection between the plate-side connector 20 and the hand-side connector 35 is difficult to disconnect, and the effect that the plate-side connector 20 or the hand-side connector 35 is hardly damaged. There is. Further, when the hand slave unit 12 is hooked on the plate slave unit 11, the connection portion between the plate side connector 20 and the hand side connector 35 is not easily obstructed, so that the hand slave unit 12 can be easily hooked on the plate slave unit 11. There is also an effect that the handset 12 that has been left is difficult to drop off.
In addition, the plate-side connector 20 is attached using the space between the main body substrate 17 and the switch substrate 19 in the storage box 14. Therefore, the space in the storage box 14 can be used effectively, and the plate slave unit 11 can be downsized.

Further, a hook 27 for hooking the hand slave unit 12 is provided so as to be rotatable at a position covering the front of the insertion hole 24. Therefore, the plate slave unit 11 can be further reduced in size as compared with the conventional connector structure in which the hook 27 and the insertion hole 24 are arranged side by side so as not to overlap each other. Furthermore, when the hand-side connector 35 is inserted into the insertion hole 24, the insertion hole 24 is exposed by rotating the hook 27, so that workability related to connector connection is not deteriorated. Furthermore, since the hook 27 in the tilted posture covers the front of the insertion hole 24, the dust or the like hardly enters the storage box 14 from the insertion hole 24.
In addition, when the plate slave unit 11 is installed with the top surface as the installation surface W, the hook 27 hangs down by its own weight and takes a standing posture. Therefore, since the hand slave unit 12 can be hooked without providing a dedicated hook or the like used in the above-described installation mode, the plate slave unit 11 is further miniaturized, which is convenient and requires fewer parts. There is also an effect that it can be achieved.

  The connector structure in the nurse call slave according to the present invention is not limited to the aspect of the above embodiment, and the entire configuration of the nurse call slave, as well as the configuration of the hook, the connector, etc. The present invention can be changed as needed without departing from the spirit of the invention.

For example, in the above embodiment, the posture of the plate-side connector 20 is such that the pin 20a faces downward with an inclination angle of 24 ° with respect to the installation surface W, but the inclination angle can be changed as appropriate. . However, the inclination angle is preferably in the range of 20 ° to 30 °.
The plate-side connector 20 can be a female connector, and the hand-side connector 35 can be a male connector.
Further, the hook 27 does not have to be rotatable or provided at a position covering the front of the insertion hole 24, and is fixed to the lid adjacent to the upper, lower, left and right of the insertion hole 24 as in the prior art. There is no problem with such a configuration.
In addition, in the above-described embodiment, a rotation mechanism is employed as a mechanism for moving the hook 27. However, a separate mechanism such as a slide mechanism may be employed instead.
