[Means for Solving the Problems] In order to achieve the above object, the present invention provides a base plate to be attached to a mounting location such as a ceiling, a mounting plate to which a CCTV camera is mounted, and a structure formed on the base plate and the mounting plate. and a plug and a socket that are selectively attached to the base plate and the mounting plate, are connected to each other at the same time as the engagement of the engagement means, and electrically connect the external device and the CCTV camera. It is something that

[0007] The engagement means includes hook-shaped engagement pieces protruding from a plurality of locations on the mounting plate, and is formed so that the engagement pieces can be inserted through a plurality of locations on the base plate. a hole, a groove formed in the circumferential direction following the hole and allowing movement of the base of the engagement piece, and formed on the side of the groove,
It is possible to provide an engagement protrusion that is irreversibly engaged when the engagement portion on the distal end side of the engagement piece that moves along the groove forcibly overcomes the groove.

[0008]

[Operation] Therefore, according to the present invention, the CCTV camera can be mounted on the ceiling etc. by engaging the mounting plate on which the CCTV camera is attached with the base plate mounted on the ceiling etc. using the engagement means. At the same time, the plug and socket can be combined to electrically connect external equipment to the CCTV camera.

is formed into a disk shape, with a central portion 2 protruding upward and a recessed portion 3 formed on the lower side. A plurality of upward protrusions 4 are formed on the outer periphery of the base plate 1 (in the illustrated example, two on each side, four in total), and a screw mounting hole 5 is provided in the center of each protrusion 4. It is formed. A hole 6 is formed in the center of the base plate 1, a part of a plug 7 is inserted into the hole 6, and the plug 7 is fixed to the base plate 1 with screws 8. The plug 7 has a core wire 9 built therein, and has a grounding portion 10 on its outer peripheral surface. One end of a connecting wire 11 is connected to the core wire 9, and the other end of the connecting wire 11 is connected to the base plate 1 with a screw 12.
It is connected to the.

As shown in FIGS. 1 and 5, the mounting plate 13
is formed into a disk shape, and a socket 15 is inserted into a hole 14 formed in the center and fixed. The socket 15 has a core wire 16 built therein, and has a grounding portion 17 on its inner peripheral surface. A CCTV camera 18 is fixedly attached to the lower surface of the mounting plate 13 with screws (not shown) using screw mounting holes 19. One end of a connection line 20 is connected to the socket 15, and the other end of the connection line 20 is connected to a printed circuit board (not shown) built into the CCTV camera 18.

[0013] The mounting plate 13 and the base plate 1 are provided with engagement means. As an example, as is particularly clear from FIG. 5, the mounting plate 13 has a plurality of engagement pieces 21 formed at approximately equal intervals around the central axis (in the illustrated example, three at approximately 120 degree intervals). ing. Each engagement piece 21 is attached to the mounting plate 13
It is cut and raised from above, and is formed into a hook shape with spring properties, and consists of a base part perpendicular to the mounting plate 13, and an engaging part perpendicular to the base part and substantially parallel to the mounting plate 13. . On the other hand, the base plate 1 is particularly
As is clear from FIG. 4, there are two engaging pieces 2 at three locations approximately equally spaced around the central axis, corresponding to each engaging piece 21.
A groove 23 is formed in the circumferential direction following each hole 22 to allow movement of the base of the engagement piece 21. An engaging protrusion 24 is provided on the side of the middle portion of the groove 23 by cutting and raising it. Each engagement protrusion 24 has sloped surfaces on both sides that gradually become higher in the circumferential direction and gradually lower in the circumferential direction from the apex, and the apex is slightly higher than the protrusion 4 of the base plate 1, as is clear from FIG. It is set to be low.

As shown in FIG. 1, the center portion 2 of the base plate 1 is inserted into a hole 26 formed at a desired mounting location such as the ceiling 25, and each protruding portion 4 is brought into contact with the lower surface of the ceiling 25. The screw 27 is screwed into the ceiling 25 through the screw attachment hole 5 and fixed, and in this state, the tip of the engagement piece 21 of the mounting plate 13 is engaged between the ceiling 25 and the apex of the engagement protrusion 24. A gap is formed through which the parts can pass. Base plate 1 has external equipment (
All signal lines 28 for video, audio, and power from (not shown)
is connected, and the external device and the plug 7 are connected via the signal line 28, the connection line 11, etc. As shown in Figures 2 and 3,
Each engagement piece 21 of the mounting plate 13 to which the CCTV camera 18 is attached is inserted into each hole 22 of the base plate 1, and the mounting plate 13, C
The CTV camera 18 and the like are forcibly rotated in the horizontal direction, and the base of each engagement piece 21 is moved along the groove 23. During this time, first, the engaging part of each engaging piece 21 uses its own elasticity to get over the engaging protrusion 24, and then the engaging part of each engaging piece 21 restores itself and cannot return to the engaging protrusion 24. , and engages in the rattling prevention state, and attaches the CCTV camera 18 to the mounting base 1.
3. It can be attached to the ceiling 25 etc. via the base plate 1 etc. During this installation, the socket 15 is fitted into the plug 7, the core wire 16 and the ground section 17 of the socket 15 are connected to the core wire 9 and the ground section 10 of the plug 7, and the external device and CC
All the video, audio, and power signal lines are connected to the TV camera 18 to enable the CCTV camera 18 to operate.

Note that the base plate 1 side may be a socket and the mounting plate 13 side may be a plug.

[0016]

As explained above, according to the present invention, by engaging the mounting plate on which the CCTV camera is attached to the base plate attached to the ceiling etc. using the engagement means,
A CCTV camera can be installed on the ceiling, etc., and at the same time, the plug and socket can be connected to connect external equipment to the CCT.
