Description

  The present invention relates to an electronic device such as an interphone.

  As an electronic device, for example, a plurality of connection lines such as a line to a telephone, a line to a modular terminal such as a wall surface, a power line (power cable), and a control signal line for transmitting and receiving an alarm signal are connected to the apparatus casing. Interphone is known.

  Such an interphone is generally attached to a wall surface or a pillar. For example, as shown in FIG. 6A, the mounting bracket 101 is fixed to the switch box 103 of the wall surface 102 using screws 104, and the engagement claw portion 101a of the mounting bracket 101 is engaged with the rear portion of the equipment casing 105. A fitting hole (not shown) is hooked and attached, or as shown in FIG. 6B, the mounting bracket 101 is fixed to the wall surface 102 (or column), and the device casing 105 is attached to the locking claw portion 101a of the mounting bracket 101. It is attached by hooking a hole to be engaged on the back surface.

  There is a demand for using such an interphone in a horizontal place such as on a desk instead of being attached to a wall or a pillar. In such a case, it is necessary to provide a support stand in order to stably place it on a horizontal place.

  It is conceivable that such a support stand is provided so as to be housed inside the equipment casing, and is used by projecting the support stand so as to be in a support state only when necessary (when placed in a horizontal place). A wiring board on which electronic components are mounted is provided, and there is a demand for compactness.

  In addition, since the intercom is often attached to a wall or a pillar, it is manufactured on the assumption that it can be attached to a wall or a pillar. By simply placing, a plurality of connection lines connected to the device casing (such as the above-mentioned line to the telephone, the line to the modular terminal such as the wall surface, the power line, the control signal line, etc.) It looks bad. Therefore, there is a demand for orderly fixing the plurality of connection lines.

By the way, a groove having a fixed cross-sectional shape for positioning the wiring is provided on the outer surface side of the housing, and a pair of gaps are formed at opposite edges of the grooves, and the inner surface of the housing is formed along the longitudinal direction of the pair of gaps. In the structure in which a pair of clamping walls is provided and a wiring is fixed in the groove by fitting a fitting to the clamping wall, the top of the clamping wall has a height along the longitudinal direction of the gap. It is known to use different inclined surfaces and fix the wiring by fitting a fitting tool at a position where the height of the holding wall is high or low depending on the diameter of the wiring (for example, see Patent Document 1).
Utility Model Registration No. 3011442 (see 0010 to 0014 and FIG. 1)

  However, in such a thing, since it is necessary to provide a space | gap or to provide a clamping wall in an inner surface side, the structure of a housing | casing (equipment casing) becomes complicated. In particular, when the number of connection lines connected to the back surface portion of the device casing is large as in the interphone described above, it becomes complicated and troublesome.

  Further, the connection lines connected to the interphone are not limited to fixed shapes with a fixed cross-sectional shape, and the number of connection lines cannot be specified. Therefore, if it is going to apply the technique of patent document 1, it needs to manufacture considering that it can respond to various aspects, and the structure of the back part of an apparatus casing becomes still more complicated.

  In addition, the intercom is usually attached to a wall surface or a pillar, and it is considered that the frequency of using the support stand in a horizontal place is very low. Considering the above, it is disadvantageous in terms of cost to make the structure of the back surface portion of the equipment casing complicated.

  On the other hand, when the interphone is attached to the wall surface, the line to the telephone and the line to the modular terminal are led out from the lower part of the equipment casing, and the signal line and the power line are wired inside the wall. In addition, when the interphone is attached to the wall surface, the above-described connection lines come up and down. Therefore, when it is attached to a wall surface or a pillar, it is only necessary to satisfy the requirement of orderly fixing a plurality of connection lines without using a good appearance and only when the support stand is used and placed on a horizontal place.

  Since it is sufficient that the support stand as described above can be used only when necessary (when placed on a horizontal place), it is conceivable that the support stand is a separate body. In this way, since it is not necessary to consider the weight reduction of the support stand, the support stand is superior in stability and easy to process compared to the case where it is lightweight and the support is unstable. It is.

  From the above examination results, the inventor holds a plurality of connection lines provided on the back side of the equipment casing as a configuration in which the support stand can be separately attached to the back side of the equipment casing. If the support stand side is provided with the function, the multiple connections are easily and neatly bundled only when placed on a horizontal place using the support stand without complicated processing on the back side of the equipment casing. The present invention has been made based on the idea that it can be held.

  The present invention provides an electronic device in which a plurality of connecting wires having different cross-sectional shapes are electrically connected to the back surface of the device casing, not only when being attached to a wall surface or a pillar, but also when being placed on a horizontal place. It is an object of the present invention to be able to perform the wiring process in a simple and attractive manner.

  According to the first aspect of the present invention, a plurality of connection wires having different cross-sectional shapes (such as a wire to a telephone, a wire to a modular terminal, a power wire, a signal wire) are electrically connected to the equipment casing and attached to a wall surface or a pillar. It is an electronic device that is used by being placed on a horizontal place such as a desk or the like, and the equipment casing is supported by a support stand when used on the horizontal place. An engaged portion is formed on the back surface, and an engaging portion that is detachably engaged with the engaged portion is formed on the support stand, and the plurality of connection lines are connected to the support stand. A holding portion for holding is formed.

  Here, holding by the holding unit is as follows: (i) when each connection line is held separately by a holder, (ii) when all connection lines are held by one holder, (iii) a plurality of connection lines In addition to the case where each group is held by a holding tool, (iv) the case where the holding stand is provided with a locking recess having a function of locking the connection line without using the holding tool is also included. . In particular, since the support stand is separate from the electronic device, the locking recess can be easily processed as in the case of (iv). Therefore, even when the number of connection lines is large, the structure is not complicated and the processing is not troublesome as in the case where such a recess is processed in the back surface portion of the equipment casing.

  In this way, the support stand is formed with a holding portion for holding a plurality of connection lines, and therefore when the support stand is used and placed on a horizontal place, the portion for holding the plurality of connection lines (for example, connection) It is not necessary to provide the device casing with a groove-like recess for storing the wire in a detachable manner. In addition, since the support stand is formed with a holding portion capable of holding the connection line, the support stand is not only applied to a wall surface or a column without special processing on the equipment casing (such as the back portion thereof). Even when placed in a horizontal place using a plurality of connecting lines, the plurality of connecting lines can be held with good appearance (by the support stand).

  The back portion of the support stand in a state in which the support stand is detachably attached to the opening forming the through-passage portion through which the connection line can be inserted or the back portion of the equipment casing. A notch part that forms a through-passage part through which the connection line can be inserted, and the through-passage part may constitute the holding part.

  In this way, since the connection line can be inserted into the through passage portion formed by the cutout portion or the opening of the support stand, when using the support stand, The process of holding the connection lines can be easily performed by allowing all the connection lines to pass through the through passage portion.

  According to a third aspect of the present invention, the support stand includes a bottom plate portion that contacts the horizontal place, and a rotating wall portion that protrudes from a peripheral edge of the bottom plate portion, and a central portion of the bottom plate portion. The holding portion that protrudes into the surrounding wall portion is provided, and an opening that forms a through-passage portion through which the connection line can be inserted with the holding portion sandwiched between the surrounding wall portion or the device casing. It is desirable to have a notch part which forms a penetration passage part which can insert the above-mentioned connecting line between the back part in the state where it was detachably attached to the back part. Here, the shape of the notch or the opening is not particularly limited, and may be a shape that can exhibit a function of bundling and holding them by inserting a plurality of connection lines into the through passage portion formed by these. That's fine.

  If it does in this way, the said penetration passage part can be formed easily and the layout which arrange | positions the said holding | maintenance part near the penetration passage part can also be implement | achieved without difficulty.

  In this case, as described in claim 4, the holding portion has a hollow box shape, and a plurality of through holes facing the through passage portion are formed, and a band-shaped member is inserted into the plurality of through holes, It is desirable that the connection line inserted through the through passage portion can be fastened and fixed to the holding portion.

  In this case, after wrapping one or a plurality of connection lines inserted into the through passage portion with one band-shaped member, both ends of the band-shaped member are inserted into the through holes, and the end portions are connected to each other. If they are connected together, the connecting wire can be fastened and fixed so as to press against the holding portion. Therefore, it is possible to reliably avoid the connection line from moving and varying in the through passage portion.

  Since it comprised as mentioned above, since this invention is made to hold | maintain several connection wires using a separate support stand, when placing in a horizontal place using a support stand, it is an equipment casing. A plurality of connection lines can be nicely bundled and held without any special processing (such as the back surface).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an interphone master unit (electronic device) when viewed from the front side when placed in a horizontal place according to an embodiment of the present invention, and FIG. FIG. 3 is a perspective view illustrating a procedure for attaching a support stand in the parent device.

  As shown in FIG. 1, a box-shaped device casing 2 of a base unit (electronic device) 1 of an interphone is configured by combining a front casing 2A and a rear casing 2B. Although not specifically shown, a wiring board on which various electronic components are mounted is housed inside the device casing 2.

  An antenna 3 for communication with a slave (not shown) is provided on the upper surface of the device casing 2 (see FIG. 4). On the front side, in order from the top, the liquid crystal display unit 4, the speaker unit 5, six small button units 6, one large button unit 7, and a storage recess (not shown) for storing various switches inside are opened and closed. An openable / closable lid 8 is provided to cover it. The lower surface portion is provided with a connector portion 9 having connectors 9A and 9B to which a line S1 to a telephone and a line S2 to a modular terminal such as a wall surface are connected.

  As shown in FIGS. 2 and 3, a central recess 11 having a relatively shallow depth is formed in the central portion on the back surface of the device casing 2, and a rectangular opening that opens the central recess 11 up and down on the upper and lower sides thereof. Shaped upper and lower notches 11a and 11b are formed. Further, near the upper, lower, left, and right corners, there are provided engaged holes 11c that are hooked on the locking claws 101a of the mounting bracket 101 described above. The central recess 11 has two inclined recesses 12a and 12b extending in the vertical direction and having the most depressed center, and a control signal line for transmitting and receiving an alarm signal to the most depressed portion. Connection portions 13a and 13b for connecting S3 and S4 are provided. They are partitioned by three projecting ribs 14a, 14b, 14c.

  Further, another recess 16 into which the power supply line S5 (power supply cord) and its connector S5a are inserted is formed in the lower left portion of the rear portion.

  The base unit 1 is not only used by being hung on a wall surface or a pillar, but a support stand 21 that supports the base unit 1 in an inclined state so that the front unit can be easily seen can be attached to and detached from the back side of the device casing 2. By attaching it, you can use it on a horizontal surface such as a desk.

  Specifically, in the central recess 11, engaged recesses 15 a, 15 a are formed on both the left and right sides slightly above the connection portions 13 a, 13 b. In the case where the device casing 2 is used in a horizontal place such as on a desk, it is possible to engage the engaging portions 21a, 21a of the support stand 21 so as to be detachable. A support stand 21 can be detachably attached to the back surface. The positions of the engaged recesses 15a and 15a are provided above the positions of the connector portion 9 (connectors 9A and 9B), the recess 16 and the connection portions 13a and 13b on the back surface of the device casing 2.

  In the state where the support stand 21 is attached to the back surface of the device casing 2 in the engagement relationship between the engaged recesses 15a and 15a and the engagement portions 21a and 21a, the back of the support stand 21 and the device casing 2 A through passage portion 21Cb is formed between the two portions. Then, by inserting the connecting line (line S1 to the telephone, line S2 to the modular terminal, signal line S3, S4, power line S5) from the lower side to the upper side through the through passage portion 21Cb, All the connecting lines can be bundled in the through passage portion 21Cb. When this is viewed from the front side, all connection lines are led out from the upper part of the device casing 2 and extend upward, so that the appearance is improved. In addition, since the connection lines can be led out in one direction (upward) in this way, there is an advantage that it is easy to perform connection work with other devices.

  As described above, a plurality of connection lines (line S1 to the telephone, line S2, to the modular terminal S2, signal lines S3, S4, and power line S5) having different cross-sectional shapes are electrically connected to the interphone base unit 1. The base unit 1 can be used by being attached to a wall surface or a pillar, or placed on a horizontal place such as a desk using the support stand 21 according to the user's selection.

  Next, the structure of the support stand 21 will be described in detail.

  The support stand 21 includes a bottom plate portion 21A that comes into contact with a horizontal plane in a horizontal place where the base unit 1 is placed. The bottom plate portion 21A includes a rectangular plate-shaped first portion 21Aa having the same width as the central recess 11 and two small rectangular plate-shaped second portions connected to both sides of the upper portion of the first portion 21Aa. (In FIG. 2, the boundary between the first portion 21Aa and the second portion 21Ab is indicated by a one-dot chain line).

  Further, a circular plate-like rubber material 22 for preventing slipping is attached to the second portion 21Ab. In the central portion of the bottom plate portion 21A, a hollow box-shaped holding portion 21B is protruded and formed integrally with the central portion of the first portion 21Aa (downward in FIGS. 2 and 3). In addition, by forming the hollow box-shaped holding portion 21B in the first portion 21Aa, a rectangular opening is formed in the first portion 21Aa. A plurality of elongate through holes 21Ba are regularly formed at equal intervals in the vertical direction on the bottom surface of the holding portion 21B, and a band-shaped member 31 (holding tool) is inserted into the plurality of through holes 21Ba as will be described later. Thus, the connection lines can be fixed to the holding portion 21B.

  A circumferential wall portion 21C that protrudes and extends in the same direction as the protruding direction of the holding portion 21B is integrally provided at the periphery of the bottom plate portion 21A (first and second portions 21Aa, 21Ab). The upper and lower portions 21Ce and 21Cf corresponding to the upper and lower surfaces of the device casing 2 in the circumferential wall 21C are formed with cutout portions 21Ca and 21Cb having a width corresponding to (the width of) the holding portion 21B. The portions 21Ca and 21Cb are located with the holding portion 21B interposed therebetween. Thereby, in a state where the support stand 21 is attached to the back surface portion of the device casing 2, the connection line can be inserted between the support stand 21 and the back surface portion of the device casing 2 by the cutout portions 21Ca and 21Cb. A through passage portion 23 is formed (see FIG. 2).

  The portions on both sides of the lower notch portion 21Ca are positioning piece portions 21Cc and 21Cc for positioning in the left-right direction by contacting the inner surface (vertical wall surface) of the central recess 11. The positioning piece 21Cc protrudes from the other part by a length corresponding to the depth of the central recess 11.

  Two slits 21Cd and 21Cd are formed in parallel to the left and right sides of the circumferential wall portion 21C in the lower portion of the first portion 21Aa (in the protruding direction of the holding portion 21b), and the slits 21Cd and 21Cd are formed. In between, the engaging part 21a which has flexibility and protrudes further than the positioning piece parts 21Cc and 21Cc is provided. In addition, the front-end | tip part of this engaging part 21a is a huge part so that it may latch elastically to the to-be-engaged recessed part 15a.

  Further, the circumferential wall portion 21C between the left and right sides of the lower cutout portion 21Cb to the slit 21Cd also protrudes by the same amount as the positioning piece portion 21Cc. Therefore, the part of the surrounding wall part 21 </ b> C and the tip part of the positioning piece part 21 </ b> Cc during this time come into contact with the bottom surface of the central recess 11 in a state where the support stand 21 is attached to the back surface part of the device casing 2.

  When the support stand 21 is attached to the back surface of the device casing 2 when used in a horizontal place such as on a desk, the various connection lines described above can be processed as follows. .

  As shown in FIG. 4, a line S1 to the telephone, a line S2 to the modular terminal, two signal lines S3 and S4, and a power line S5 are formed between the support stand 21 and the back surface of the equipment casing 2. Through the through-passage 23, the insertion is made without loosening so as to pass from the lower side to the upper side (in the X direction in FIG. 4). Thereby, although each line S1-S5 which passed through the penetration channel | path part 23 is bundled through the penetration channel | path part 23, since each line S1-S5 can move independently, as shown in detail in FIG. It is also possible to fix to the holding portion 21 </ b> B of the support stand 21 by using flexible (three in this example) belt-like member 31 (holding tool). That is, the band-like member 31 is divided into lines having different cross-sectional shapes (a group of lines S1 to the telephone, a group of lines S2 to the modular terminal, a group of two signal lines S3 and S4, and a power line S5. , For each, it can be fixed to the holding portion 21 </ b> B (the inner surface side) using the belt-like member 31. Specifically, after wrapping each line or group having a different cross-sectional shape with a single band-shaped member (holding tool), both ends of the band-shaped member 31 are inserted into the through hole 21Ba and led to the upper surface side. When the derived end portions are connected and combined, the connection lines or groups can be fastened and fixed so as to press against the holding portion 21B. Since such a belt-like member 31 is used to fasten and fix each connection line or group, it can be held regardless of the cross-sectional shape of the connection line.

The embodiment described above can be modified as follows.
(i) Although the plurality of connecting lines are held by the holding portion 21B through the through passage portion 23, it is not always necessary to pass through the through passage portion. For example, as shown by a two-dot chain line in FIG. It is also possible to provide a groove-like recess 21Cg serving as a holding portion on the outer surface 21Ch of the support stand 21 and hold the connection wire by fitting the connection line into the recess 21Cg so as not to be removed by the holder 17. In this case, it is not necessary to form the through passage portion with the support stand attached, but the concave portion and the through passage portion may be used in combination. That is, a part of the connection line may be passed through the through-passage part, and the remaining connection line may be held by the recess. In this way, in particular, when the cross-sectional shape of the connection line such as the line to the telephone, the line to the modular terminal or the power supply line is known in advance, the cross-section is held until it is attached using the recess. Other connection lines whose shapes are not known can be configured to be bundled and held using the through passage portion. Even if the recess is formed in this way, and the through passage portion is further formed, since the support stand is a separate body and the degree of freedom of processing is high, it is planned to be provided on the wall surface and the pillar. Compared with the case where the above-described recess (holding portion) is provided on the back surface portion of the equipment casing in which a groove-like recess for attachment or the like is formed, the processing is easier. Moreover, the site | part which provides such a recessed part may be any part of a support stand, and is not restrict | limited in particular.
(ii) Since the support stand is attached to the back surface portion of the equipment casing, the inside of the through passage portion formed between the support stand and the back surface portion has an effect of bundling them even if only a plurality of connection lines are passed. It is also possible to make a part function as a holding part and to bundle a plurality of connecting wires by passing through the through-passage part and hold it on the support stand. In this case, in order to enhance the bundling effect, it is possible to adjust the size and shape of the through passage portion (the size of the notches 21Ca and 21Cb in the above embodiment). For example, it is possible to provide a plurality of notches having different sizes and shapes. Moreover, it is also possible to comprise a through-passage part with the opening provided in the support stand instead of a notch part.
(iii) When a plurality of connection lines are held in the holding portion 21B, it is not necessary to use a separate strip-shaped member 31 for each connection line having a different cross-sectional shape as in the above-described embodiment. All the connecting lines having different cross-sectional shapes can be bundled together and held together by the belt-like member or another holder.
(iv) It is not necessary to use all the through holes 21Ba for holding the connection lines. For example, every other through hole may be used so that unused through holes may remain. It is also possible to appropriately change the shape and the interval at which the through hole is provided according to the cross-sectional shape of the connection line.
(v) In the above-described embodiment, the sizes of the notches 21Ca and 21Cb are the same, but the opening area of the upper notch 21Cb from which the connection line is led is set to the lower side where the connection line is introduced. It is also possible to improve the appearance by making it smaller than the notch 21Ca so that the connecting wires are more bundled and held.
