  This security communication device is preferably made as inconspicuous as possible so that an intruder or the like in the building does not notice its presence in order to prevent destruction or alteration of the device. Therefore, it has been desired for the security communication device to reduce the size of the entire device. On the other hand, the miniaturized security communication device has a narrow interior, and it is difficult to accommodate wiring such as power supply wiring inside the device. Conventionally, when installing a security communication device, if the external wiring is drawn into the device, the length of the drawn-in wiring may remain. Since the security communication device that has been downsized cannot accommodate the excess wiring inside the device, the wiring may be left around the device. In this case, although the security communication device is downsized, there is a problem that the device becomes conspicuous as a result of excess wiring around the device. In addition, the beauty around the device was damaged.

  Accordingly, the inventors of the present invention have devised a configuration in which an intermediate bracket member capable of accommodating excess external wiring is selectively used when the main body of the security communication device is attached to a wall surface or the like. Specifically, when wiring is left around the device, an intermediate bracket member is interposed between the main body portion and the wall surface portion, and external wiring is accommodated in the intermediate bracket member, so that the communication device for security is conspicuous. I devised to eliminate. Then, attach the intermediate bracket member to the mounting bracket so that the type and number of screws used when attaching the security communication device to the wall or the like can be the same when using the intermediate bracket member and when not using it. A fixed structure was devised. By adopting this structure, the mounting operation is facilitated. However, while security communication devices are required to devise a device that can improve the mountability of the device, the security communication device must be fixed so that it does not fall off the mounting bracket when an unexpected external force is applied. There is a need for ingenuity that further enhances sex. It is an object of the present invention to provide a technique for preventing unauthorized release or unexpected dropping of a device while facilitating the mounting workability of a security communication device.

In the case of the second mounting method, the main body side case 400 is fixed to the mounting bracket 200 via the intermediate bracket member 300.

  The intermediate bracket member 300 includes a substantially rectangular bracket-side main surface portion 301 and a frame-shaped bracket-side outer peripheral surface portion 310 formed on the outer periphery of the bracket-side main surface portion 301. In the intermediate bracket member 300, a bracket side wiring housing portion WS for housing the wiring W connected to the internal device 120 is formed in a region surrounded by the bracket side outer peripheral surface portion 310. A bracket side wiring opening 340 for allowing the wiring W extending from the internal device 120 to pass through the back side of the intermediate bracket member 300 is formed in the bracket side main surface portion 301 as required (FIG. 12). The opening end formed by the bracket side outer peripheral surface portion 310 has substantially the same shape as the outer peripheral portion of the main body side main surface portion 401. The intermediate bracket member 300 supports the main body portion 100 in a state where the open end of the bracket side outer peripheral surface portion 310 is in contact with the main body side main surface portion 401 of the main body side case 400. The security communication device 10 attached by the second attachment method may connect the wiring W drawn inside to the internal device 120 through at least one of the wiring routes shown in FIGS. it can.

  For example, as shown in FIG. 10, when the wiring W having the mounting surface 20 is drawn into the security communication device 10, the security is performed via the notch CP formed in an arbitrary portion of the bracket side outer peripheral surface 310. It can be drawn into the communication device 10 for use. In FIG. 10, as an example of the position where the notch portion CP is formed, the notch portion CP is formed in the vicinity of the right end portion of the upper surface of the bracket-side outer peripheral surface portion 310. The leading end of the drawn wire W is connected to a predetermined position of the internal device 120. Further, the wiring W between the tip end portion and the notch portion CP is accommodated in the bracket side wiring accommodating portion WS. The wiring W drawn from the cutout portion CP is connected to a predetermined position of the internal device 120 through the main body side wiring opening 440 while changing the wiring direction inside the bracket side wiring housing portion WS. Note that the position where the notch CP is formed is not limited to the position shown in FIG. For example, as shown in FIG. 11, the notch CP may be formed near the right end of the lower surface of the bracket-side outer peripheral surface 310 to draw in the wiring W. As another example, cutout portions CP may be formed on the left and right side surfaces of the bracket-side outer peripheral surface portion 310. Even in these cases, the wiring drawn from the cutout portion CP is changed in the wiring direction inside the bracket-side wiring housing portion WS, and a predetermined value of the internal device 120 is set via the body-side wiring opening 440. Can be connected to a location. At this time, the excessively long wiring W can be accommodated inside the bracket-side wiring accommodating portion WS. Therefore, it is possible to suppress the wiring W having an excessive length from being conspicuous outside the security communication device 10.

  On the other hand, for example, as shown in FIG. 12, when the wiring W taken out from the back side of the attachment surface 20 through the opening 21 provided in the attachment surface 20 is drawn into the security communication device 10, first, The mounting bracket 200 is attached so that the opening 21 provided and the bracket-side opening 240 provided in the mounting bracket 200 communicate with each other. Then, the wiring W is taken out from the back side of the mounting surface 20 through the metal fitting side opening 240 of the mounting metal 200. The wiring W taken out from the metal fitting side opening 240 can be inserted into the bracket side wiring opening 340 and the main body side wiring opening 440 and connected to a predetermined position of the internal device 120. At this time, the wiring W with an excessive length can be accommodated in the bracket-side wiring accommodating portion WS. As described above, the security communication device 10 is the most suitable among the wiring paths illustrated in FIGS. 7 to 12 in consideration of the wiring conditions around the security communication device 10 and the size of the device itself. An inconspicuous configuration can be selected.

The groove 315 can be formed anywhere on the four bracket outer peripheral plane portions 311 to 314.

  FIG. 20 is an explanatory view illustrating the procedure for attaching the intermediate bracket member 300 to the attachment fitting 200. As shown in FIG. 20A, first, the pair of bracket-side hook portions 220, 230 are inserted into the pair of bracket-side hook engaging portions 320, 330 so that the bracket-side main surface portion 301 and the bracket-side main surface portion 201 are in contact with each other. The intermediate bracket member 300 is pushed in to the position where it does. At this time, as shown in FIG. 20B, the leaf spring portion 361 is warped by the metal fitting side engaging portion 250, and the tip end portion including the locking claw portion 362 and the lever portion 363 of the bracket side engaging portion 360 is moved. Pushed up. In this state, as shown in FIG. 20C, when the intermediate bracket member 300 is slid downward, the warp of the leaf spring portion 361 is eliminated, and the tip end portion of the bracket side engaging portion 360 returns to the original position. . As a result, the locking claw portion 362 enters the lower side of the metal fitting side engaging portion 250 and is locked to the end surface 251 of the lower end portion of the metal fitting side engaging portion 250 so that the bracket side engaging portion 360 and the metal fitting side engaging portion are engaged. 250 is engaged. In this manner, in the state where the bracket side engaging portion 360 and the metal fitting side engaging portion 250 are engaged, the locking claw portion 362 is caught by the end surface 251 at the distal end portion of the metal fitting side engaging portion 250. The upward movement of the bracket member 300 is restricted. In this state, the movement of the intermediate bracket member 300 in the front / rear / left / right direction is restricted by the engagement of the pair of bracket side hook engaging portions 320, 330 and the pair of metal fitting side hook portions 220, 230. The member 300 is fixed to the mounting bracket 200. Thus, according to the present reference example, the intermediate bracket member 300 can be easily attached to the mounting bracket 200 without using screws. Therefore, the type and number of screws used when attaching the security communication device 10 to a wall surface or the like can be kept unchanged between the case where the intermediate bracket member 300 is used and the case where the intermediate bracket member 300 is not used, thereby improving attachment workability. Can be achieved. In addition, it is possible to prevent unnecessary materials from being generated due to excessively unused screws.

  FIG. 21 is an explanatory view illustrating the procedure for removing the intermediate bracket member 300 from the mounting bracket 200. As shown in FIG. 21 (a), first, the lever portion 363 is pushed up in the first direction D1, thereby releasing the engagement between the locking claw portion 362 and the distal end portion of the metal fitting side engaging portion 250. After that, as shown in FIG. 21B, the intermediate bracket member 300 is slid upward (first direction D1). Thereby, the engagement between the pair of bracket side hook engaging portions 320 and 330 and the pair of metal fitting side hook portions 220 and 230 is released, and the intermediate bracket member 300 can be detached from the metal fitting 200. Thus, since the lever portion 363 protrudes from the leaf spring portion 361 of the bracket side engaging portion 360, the intermediate bracket member 300 is engaged by pressing the lever portion 363 in the first direction D1 with a finger or the like. The engagement between the pawl portion 362 and the metal fitting side engagement portion 250 can be easily released. In this reference example, the direction in which the lever portion 363 is released and the direction in which the intermediate bracket member 300 is slid in order to release the engagement state between the intermediate bracket member 300 and the mounting bracket 200 are the same (first direction). Direction D1) (FIG. 21B). Therefore, the release of the lever portion 363 and the removal of the intermediate bracket member 300 from the mounting bracket 200 can be performed by a single operation.

  FIG. 22 is an explanatory diagram showing an example of the effect of this reference example. The description will be made assuming that the wiring W accommodated in the bracket-side wiring accommodating portion WS exists in the broken line portion in FIG. As described above, in the intermediate bracket member 300, the bracket-side wiring housing part WS is located on the side of the lever part 363 in the first direction D1. Therefore, when the wiring W accommodated in the bracket-side wiring accommodating portion WS faces the lever portion 363, the wiring W causes the lever portion 363 to move in a direction opposite to the first direction D1 (release direction) (second direction). Will be pressed in the direction D2). That is, according to this configuration, the lever portion 363 is suppressed from being pressed in the first direction D1 by the wiring W. Further, according to this configuration, the wiring W presses the lever portion 363 in the second direction D2, the locking claw portion 362 is pushed toward the mounting bracket 200, and the locking claw portion 362 and the bracket side engagement are engaged. The locked state with the part 250 becomes closer. Therefore, it is possible to make it difficult for the security communication device 10 attached to the attachment surface 20 to be detached from the attachment surface 20.

  Generally, since the security communication device 10 needs to be inconspicuous, the intermediate bracket member 300 needs to be downsized. Due to the downsizing of the intermediate bracket member 300, the bracket-side wiring housing portion WS is also reduced, so that excess wiring W is pushed into the bracket-side wiring housing portion WS. On the other hand, in order to reduce the size of the intermediate bracket member 300, it is necessary to bring the bracket side wiring housing portion WS and the lever portion 363 close to each other. For these reasons, the inventors of the present invention can accommodate the intermediate bracket member 300 in the bracket-side wiring housing portion WS when the lever portion for releasing the engagement between the intermediate bracket member 300 and the mounting bracket 200 is provided. It has been found that the lever portion is easily pressed by the formed wiring W. For example, when the security communication device 10 is attached, unintentional release of the engagement is likely to occur due to the pressing of the lever portion by the wiring W. Therefore, in this reference example, the lever portion 363 is disposed so that the bracket side wiring accommodation portion WS is positioned on the first direction D1 side of the lever portion 363, and is accommodated in the lever portion 363 and the bracket side wiring accommodation portion WS. It is comprised so that wiring may face. As a result, the lever portion 363 is suppressed from being pressed in the first direction D1 by the wiring W while the size of the intermediate bracket member 300 is reduced.

  According to the security communication device 10 of the present reference example described above, the security communication device 10 can be made inconspicuous so that an intruder or the like in the building does not notice its presence. Specifically, when external wiring is drawn into the security communication device, if there is not enough wiring around the device, or if the length is inconspicuous, FIGS. As shown in FIGS. 7 to 9, the main body 100 of the security communication device 10 can be directly fixed to the mounting surface 20 without using the intermediate bracket member 300. Therefore, the size of the security communication device 10 can be suppressed. On the other hand, when the external wiring is drawn into the security communication device, if the length of the wiring is conspicuous around the device, as shown in FIGS. 4 to 6 and FIGS. By using 300, it is possible to change the wiring direction in the bracket side wiring housing part WS inside the intermediate bracket member 300 and connect to the main body part 100. As a result, the security communication device 10 is suppressed from being noticeable by the wiring W around the security communication device 10. Moreover, according to this structure, since the main-body part 100 of the security communication apparatus 10 can be selectively fixed to the attachment surface 20 using the intermediate | middle bracket member 300, it is not conspicuous according to the condition of an attachment place. A configuration can be selected.

  Further, according to the security communication device 10 of the present reference example, the attachment method for directly attaching the main body side case 400 to the mounting bracket 200 and the attachment for mounting the main body side case 400 to the mounting bracket 200 via the intermediate bracket member 300. The method can be similar. Moreover, the number of screws used for attachment can be made the same. Specifically, when the main body side case 400 is directly attached to the mounting bracket 200, unlike the case where the intermediate bracket member 300 is mounted to the mounting bracket 200, the main body side insertion hole 450 is used without using the bracket side engaging portion 250. The screw inserted through is screwed into the metal fitting side female thread portion 211 and fixed. On the other hand, when the main body side case 400 is attached to the mounting bracket 200 via the intermediate bracket member 300, the screws inserted through the main body side insertion hole 450 and the bracket side insertion hole 350 are screwed into the bracket side female thread portion 211. And fix. Thus, the method of directly attaching the main body side case 400 to the mounting bracket 200 is different from the method of mounting the intermediate bracket member 300 to the mounting bracket 200, and the main body side case 400 is attached to the mounting bracket 200 via the intermediate bracket member 300. By using the same mounting method as that attached to the bracket, the number of screws used can be the same when the intermediate bracket member 300 is used and when not used, and generation of unnecessary screws can be suppressed. Further, since the attachment method for directly attaching the main body side case 400 to the attachment metal fitting 200 is the same as the attachment method for attaching the main body side case 400 to the attachment metal fitting 200 via the intermediate bracket member 300, the workability of attachment is improved. Can be achieved.

B. Embodiment:
The security communication device according to the embodiment of the present invention will be described with reference to FIGS. In FIG. 23 to FIG. 29, the same reference numerals are given to the components common to the above-described reference example. Moreover, the code | symbol which attached | subjected the alphabet to the end of the code | symbol attached | subjected to the component part in the said reference example is attached | subjected to the component part corresponding to the component part in said reference example.

  23A to 23E are respectively a schematic front view, a schematic top view, a schematic bottom view, a schematic right side view, and a schematic left side view of the intermediate bracket member 300A in the present embodiment. FIG. 24 is a schematic perspective view showing the vicinity of the bracket-side engagement portion 360A in the present embodiment, and is a view when the intermediate bracket member 300A is viewed from the front side. FIG. 25 is a schematic cross-sectional view of the bracket side engaging portion 360A in the BB cut of FIG. The details of the tip 361c of the leaf spring 361 of the bracket side engaging portion 360A are shown enlarged in each of the two balloons in FIG.

  The security communication device of the present embodiment has substantially the same configuration as the security communication device 10 of the reference example except that the configuration of the intermediate bracket member 300A is different. Further, the intermediate bracket member 300A in the present embodiment has substantially the same configuration as the intermediate bracket member 300 in the reference example except that the configuration of the bracket side engaging portion 360A is different.

  The intermediate bracket member 300 </ b> A (FIG. 23) in the present embodiment is held by engagement with the mounting bracket 200 arranged on the back side and the main body portion on the front side, like the intermediate bracket member 300 of the reference example. Hold 100. The attachment of the mounting bracket 200 and the main body 100 to the intermediate bracket member 300A will be described later.

  The bracket side engaging portion 360A in the present embodiment includes a leaf spring portion 361, a locking claw portion 362A, and a lever portion 363A (FIGS. 24 and 25). As described in the above reference example, the leaf spring portion 361 is a plate-like portion that extends in the vertical direction and can be elastically deformed in the thickness direction. A base end portion 361 b above the leaf spring portion 361 is connected to the bracket side main surface portion 301. The distal end portion 361c below the leaf spring portion 361 is elastically rotated around the fulcrum on the proximal end side.

  The locking claw portion 362A protrudes toward the back side to which the mounting bracket 200 is attached at the tip portion 361c of the leaf spring portion 361 (FIG. 25). Similarly to the locking claw 362 described in the above reference example, the locking claw 362A comes into contact with the end surface 251 at the distal end portion of the metal fitting side engaging portion 250 on the locking surface 362s facing upward. It is locked to the metal fitting side engaging portion 250 (details will be described later).

  A curved surface portion 390 is formed at a corner portion where the locking claw portion 362A and the leaf spring portion 361 intersect (within the balloon in FIG. 25). The curved surface portion 390 is a surface having a rounded corner portion between the locking claw portion 362A and the leaf spring portion 361, and forms a curved surface that protrudes from the tip of the locking claw portion 362A toward the corner portion. ing. By forming the curved surface portion 390, the concentration of stress at the base end portion of the locking claw portion 362A is suppressed, and the strength of the bracket side engaging portion 360A is increased.

  The locking surface 362s of the locking claw portion 362A is slightly inclined downward toward the direction in which the locking claw portion 362A protrudes, that is, in the direction from the base end portion to the distal end portion of the locking claw portion 362A. ing. Thus, the external force applied to release the engagement state between the locking claw portion 362A and the metal fitting side engagement portion 250 can be reduced, and the detachability of the intermediate bracket member 300A from the attachment metal fitting 200 can be reduced. Has been enhanced. Further, since the locking surface 362s is inclined downward, it is easy to remove the mold used when the intermediate bracket member 300A is injection molded.

  The lever portion 363A (FIGS. 24 and 25) protrudes in the direction opposite to the locking claw portion 362A at the tip portion 361c of the leaf spring portion 361. The lever portion 363 </ b> A is an operation portion to which an external force in the first direction D <b> 1 is applied when the locking claw portion 362 </ b> A is released from the locking state with respect to the metal fitting side engaging portion 250, as described in the above reference example. As a function. In the present embodiment, the lever portion 363 </ b> A is close to the back surface of the main body side main surface portion 401 of the main body side case 400 when the main body portion 100 is normally attached to the intermediate bracket member 300 </ b> A as prescribed. It extends to the position to do. Thus, even when an unexpected external force in the first direction D1 is applied to the security communication device, the intermediate bracket member 300A is prevented from falling off the mounting bracket 200. (Details will be described later). The lever portion 363A corresponds to a subordinate concept of the protruding portion in the present invention.

  In the present embodiment, the lever portion 363A is provided at a position offset to the fulcrum side of the leaf spring portion 361 with respect to the locking claw portion 362A in the direction in which the leaf spring portion 361 extends. Thus, when an external force in the first direction D1 is applied to the lever portion 363A, the distal end portion 361c of the leaf spring portion 361 is easily rotated from the back side toward the front side. Accordingly, the engagement state between the bracket side engaging portion 360A and the metal fitting side engaging portion 250 through the operation of the lever portion 363A is facilitated, and the intermediate bracket member 300A can be detached from the attachment metal fitting 200. Has been enhanced.

  In the present embodiment, the lever portion 363A is provided with a pair of upper rib portions 391a and 391b and a pair of lower rib portions 392a and 392b (FIGS. 24 and 25). The pair of upper rib portions 391a and 391b are formed so as to protrude upward on the upper surface of the lever portion 363A, that is, the fulcrum side surface of the leaf spring portion 361. In the lever portion 363A, the first upper rib portion 391a is formed at the left end portion, and the second upper rib portion 391b is formed at the right end portion. The pair of upper rib portions 391a and 391b corresponds to a subordinate concept of the rib portion and the fulcrum side rib portion in the present invention.

  Each upper rib portion 391a, 391b is formed from the distal end portion of the lever portion 363A to the proximal end portion, and is connected to the leaf spring portion 361 at the proximal end portion. By forming the upper rib portions 391a and 391b, the lever portion 363A is prevented from being broken between the proximal end portion and the distal end portion. Further, the strength of the connecting portion between the lever portion 363A and the leaf spring portion 361 is increased.

  In the present embodiment, corners where the upper rib portions 391a, 391b and the leaf spring portions 361 intersect are rounded to form a curved surface that is convex in the direction from the tip of the lever portion 363A toward the corner portion. A curved surface portion 391s is formed (in the balloon of FIG. 25). Thereby, when an external force in the second direction D2 is applied to the lever portion 363A, stress concentration is suppressed from occurring in the connecting portion between the lever portion 363A and the leaf spring portion 361.

  The pair of lower rib portions 392a and 392b protrude downward on the lower surface of the lever portion 363A, that is, on the surface opposite to the fulcrum of the leaf spring portion 361 (FIG. 25). In the lever portion 363A, the first lower rib portion 392a is formed at the left end portion, and the second lower rib portion 392b is formed at the right end portion.

  Each of the lower rib portions 392a and 392b is formed only on the base end portion side of the lever portion 363A, and is not formed on the distal end side. Each lower rib portion 392a, 392b is connected to a leaf spring portion 361. As a result, the strength of the connecting portion between the lever portion 363A and the leaf spring portion 361 is increased.

  Further, in the lever portion 363A, since the lower rib portions 392a and 392b do not extend to the distal end side, the user's finger pressing the lever portion 363A is prevented from coming into contact with the lower rib portions 392a and 392b. ing. Therefore, the user is prevented from feeling uncomfortable, and the operability of the lever portion 363A is enhanced. The pair of lower rib portions 392a and 392b corresponds to a subordinate concept of the rib portion and the anti-fulcrum side rib portion in the present invention.

  In the present embodiment, a curved surface portion 393 is formed at a corner portion where the lower surface of the lever portion 363A and the leaf spring portion 361 intersect (FIG. 25). The curved surface portion 393 is formed by rounding a corner portion between the lower surface of the lever portion 363A and the leaf spring portion 361, and upwards, that is, the leaf spring portion 361 or the lever portion 363. A convex curved surface is formed toward the base end. In the present embodiment, the curved surface portion 393 is formed between the pair of lower rib portions 392a and 392b.

  Since the curved surface portion 393 is formed at the base end portion of the lever portion 363A, when an external force is applied to the lever portion 363A, stress concentration occurs in the connecting portion between the lever portion 363A and the leaf spring portion 361. It is suppressed. Therefore, the breakage that causes the lever portion 363A to drop off from the leaf spring portion 361 is suppressed.

  FIG. 26 is a schematic diagram illustrating a method of attaching the mounting bracket 200 and the main body 100 to the intermediate bracket member 300 </ b> A when the security communication device of the present embodiment is attached to the mounting surface 20. FIGS. 26A to 26C illustrate steps of attaching the mounting bracket 200 and the main body 100 to the intermediate bracket member 300A in the order of steps. In FIG. 26, only the main body side case 400 is shown in the main body 100 for convenience. The cross sections of the mounting bracket 200, the intermediate bracket member 300A, and the main body side case 400 illustrated in FIGS. 26A to 26C are cut positions corresponding to the BB cut in FIG. It is in.

  When the security communication device of this embodiment is attached to the attachment surface 20, first, the attachment metal fitting 200 is fixed to the attachment surface 20 (FIG. 26A). Then, the intermediate bracket member 300A is attached by the same procedure as described with reference to FIG. 20 in the reference example (FIG. 26B). At this time, the locking claw portion 362A of the bracket side engaging portion 360A is locked to the tip end portion of the metal fitting side engaging portion 250 of the mounting bracket 200. After the intermediate bracket member 300A is attached and held on the mounting bracket 200, the main body side case 400 of the main body 100 is attached to the intermediate bracket member 300A (FIG. 26C).

  FIG. 27 is a schematic perspective view showing the distal end portion 250 c of the metal fitting side engaging portion 250. In the present embodiment, the mounting bracket 200 is formed by a punching process in a direction from the front side to the back side as indicated by the arrow FP. An end surface 251 on the front end side of the metal fitting side engaging portion 250 is a shear surface, and is a surface that is easy to slide in a direction along the shear direction of the arrow FP. Further, a sag 253 is generated between the front surface 252 and the end surface 251 on the front end side of the metal fitting side engaging portion 250 by press punching. Also by having this sag 253, the locking claw portion 362A of the bracket-side engaging portion 360A that is locked is easily slid to the front side.

  In addition, as described above, in the present embodiment, the locking surface 362s (FIG. 27) of the locking claw portion 362A is slightly inclined downward, and the locking claw portion 362A is attached to the bracket side engagement. It has a structure that is slippery with respect to the joint. Thus, in this embodiment, both the metal fitting side engaging portion 250 and the locking claw portion 362A have a structure that is easy to slip, and the metal fitting side engaging portion 250 and the bracket side engaging portion 360A are engaged. State formation and release are facilitated.

  FIG. 28 is a schematic cross-sectional view showing an engaged state between the bracket side engaging portion 360A and the metal fitting side engaging portion 250. As described above, in the engaged state in which the bracket side engaging portion 360A and the metal fitting side engaging portion 250 are normally engaged as specified, the locking surface 362s of the locking claw portion 362A is connected to the metal fitting side engagement. The end portion 251 of the joint portion 250 is brought into contact with the end surface 251 and locked. In the engaged state, the lever portion 363 </ b> A of the present embodiment is positioned such that the tip end portion 363 c is located at a close position separated from the back surface of the main body side main surface portion 401 in the main body side case 400 by a predetermined distance Ds. It is configured. The distance Ds may be, for example, about 0.1 to 1.0 mm. Thereby, when attaching the main body part 100 to the intermediate bracket member 300A, the lever part 363A is suppressed from being sandwiched between the main body side case 400 and the metal fitting side engaging part 250 and being damaged.

  Here, the predetermined distance Ds is a value smaller than the height CH at which the locking claw portion 362A protrudes from the leaf spring portion 361. The predetermined distance Ds is the locking claw 362A when the main body 100 is normally attached to the mounting bracket 200 via the intermediate bracket member 300A (hereinafter also referred to as “normally attached state”). This corresponds to a distance in which the rotational movement is allowed. If the predetermined distance Ds is set to a value smaller than the height CH of the locking claw portion 362A, the engagement state between the bracket side engagement portion 360A and the metal fitting side engagement portion 250 is released in the normal attachment state. Thus, the rotational movement of the engaging claw portion 362A is limited.

  When an external force in the first direction D1 is applied to the security communication device, the internal bracket-side engagement portion 360A is opposite to the first direction D1, as indicated by an arrow FD. Force acts in the direction. Then, a force is generated to rotate and move the lever portion 363A and the locking claw portion 362A in the direction of the front side indicated by the arrow RD. In the security communication device according to the present embodiment, as described above, the rotational movement of the locking claw portion 362A is restricted in the normal attachment state. Therefore, even if such a force is generated and the locking surface 362s of the locking claw 362A slides with respect to the metal fitting side engaging portion 250, the engagement between the bracket side engaging portion 360A and the metal fitting side engaging portion 250 is caused. The combined state is prevented from being released.

  Further, when forcibly removing the intermediate bracket member 300A from the mounting bracket 200, the bracket outer peripheral plane portions 311 to 314 of the intermediate bracket member 300A spread outward, and the intermediate bracket member 300A is deformed in a direction of decreasing the thickness. There is a case. In this case, the distance Ds between the back surface of the main body side main surface portion 401 and the tip portion 363c of the lever portion 363A is smaller than a specified distance. Therefore, the allowable range in which the locking claw portion 362A can rotate is further reduced, and the engagement state between the locking claw portion 362A and the metal fitting side engagement portion 250 is more difficult to be released.

  As described above, in the security communication device according to the present embodiment, even when the locking claw portion 362A rotates and moves in the direction away from the metal fitting side engagement portion 250 in the normal attachment state, the lever portion 363A is not mounted on the main body side. Abutting on the case 400, its rotational movement is limited. Accordingly, the formation and release of the engagement state between the locking claw portion 362A and the metal fitting side engagement portion 250 is facilitated, while the bracket side engagement portion 360A and the metal fitting are in the normal attachment state. It is possible to prevent the engagement state with the side engagement portion 250 from being released by an unexpected external force or an unauthorized removal operation.

  Here, the distance Ds between the distal end portion 363c of the lever portion 363A and the main body side main surface portion 401 of the main body side case 400 when in the normal attachment state is smaller than the thickness MT of the metal fitting side engaging portion 250. It may be. Even if the distance Ds is such a value, the lever portion 363A rotates and moves so that the engagement state between the bracket side engagement portion 360A and the metal fitting side engagement portion 250 is released in the normal attachment state. This is suppressed.

  Further, when in the normal attachment state, it is desirable that the locking claw portion 362A protrudes in the direction from the front side to the back side rather than the back surface 254 at the distal end portion of the metal fitting side engaging portion 250. The length CL of the locking claw portion 362A protruding from the back surface 254 is preferably larger than the distance Ds. Accordingly, even if the lever portion 363A rotates and contacts the main body side case 400, the locking claw portion 362A can be positioned at a position where it is locked to the tip end portion of the metal fitting side engaging portion 250. . Therefore, the engagement state between the bracket side engaging portion 360A and the metal fitting side engaging portion 250 is suppressed from being released.

  In the present embodiment, when in the normal attachment state, the lever portion 363A is surrounded by the step portion 405 and the main body side outer peripheral surface portion 410 in the main body side main surface portion 401 of the main body side case 400, and the strength is increased. Opposite the local surface region 406. Therefore, even if the lever portion 363A rotates and contacts, the main body side case 400 is prevented from being damaged.

  FIG. 29 is a schematic diagram illustrating an example of a state when the main body side case 400 is attached to the intermediate bracket member 300A. In FIG. 29, the intermediate bracket member 300 is not normally attached to the attachment fitting 200, and the main body side case 400 is attached with the bracket side engagement portion 250 being pushed up by the bracket side engagement portion 250. The state which is going to be done is illustrated. In this state, the lever portion 363A protrudes toward the main body side case 400 more than in the normal attachment state. Therefore, attachment of the intermediate bracket member 300A is hindered by the lever portion 363A. Thus, with the intermediate bracket member 300A of the present embodiment, it is possible to prevent the intermediate bracket member 300A and the main body portion 100 from being attached to the mounting bracket 200 in an incorrect state.

  As described above, according to the security communication device of the present embodiment, as described in the reference example, by using the intermediate bracket member 300A, the extra wiring W remains exposed to the outside. It is suppressed. Moreover, the screw used for fixation can be made the same in the case where the intermediate bracket member 300A is used and the case where the intermediate bracket member 300A is not used, and the attachment workability to the attachment surface 20 of the security communication device is enhanced. Furthermore, while the engagement state between the locking claw portion 362A and the metal fitting side engagement portion 250 is easily formed and released, an unexpected external force is applied to the security communication device in the normal attachment state. Even if it is the case, it is suppressed that the latching state of the latching claw part 362A and the metal fitting side engaging part 250 is cancelled | released by the lever part 363A. Therefore, the main body 100 is prevented from falling off the mounting bracket 200. In addition, according to the security communication device of the present embodiment, various functions and effects described in the reference example and the present embodiment can be achieved.
