As shown in these figures, the lens assembly 10 has a lens 11 mounted on a front surface thereof, and an image pickup device portion 13 provided on a rear surface thereof. Therefore, the lens assembly 10 converts an image recognized by the front lens 11 into an electrical signal through the image pickup device unit 13. In this case, a plurality of lenses (not shown) having a zoom function for enlarging or reducing an image may be further provided inside the lens assembly 10.

One or more circuit board portions 20 are disposed to contact the lens assembly 10. Each of the circuit board portions 20 is formed in a substantially rectangular plate shape, and is individually disposed on a side surface of the lens assembly 10. At this time, each of the circuit board portions 20 may be electrically connected to each other by a cable. However, in the present embodiment, three circuit board portions 20 are provided and disposed on three side surfaces of the lens assembly 10, respectively.

The first housing 30 and the second housing 40 form the exterior of the lens assembly 10 and the circuit board unit 20. In other words, the lens assembly 10 and the circuit board unit 20 are embedded in the first and second housings 30 and 40 having a substantially rectangular cross section when they are combined. To this end, each of the housings 30 and 40 is bent at a right angle at the center to be composed of first plates 30a and 40a and second plates 30b and 40b, respectively. do. At this time, the housings 30 and 40 are disposed to face each other, and are coupled through the screws 50 at positions corresponding to each other. That is, the first plate 30a of the first housing 30 and the second plate 40b of the second housing 40 contact each other, and the second plate 30b of the first housing 30 and the second housing ( The first plate 40a of 40 is contacted and engaged via the screw 60.                     

However, when the housings 30 and 40 are connected to each other to form an exterior, the housings 30 and 40 and the lens assembly 10 may be fixed to the inside of the housings 30 and 40. It is necessary to connect). Due to this need, the first housing 30 is provided with a recessed coupling part 31 and an extension coupling part 33 for coupling with the lens assembly 10.

In other words, the recess coupling portion 31 is partially cut and recessed in the first plate 30a of the first housing 30, and the through hole 31a for coupling with one side of the lens assembly 10 is formed. Is formed.

To combine. Therefore, for this purpose, a plurality of through holes 33a are formed in the extension coupling part 33. At this time, the extension coupling part 33 is a predetermined distance from the edge of the first plate 30a of the first housing 30 so as not to cause interference when the first housing 30 is connected to the second housing 40. It is bent at spaced points. The separation point is preferably formed at a point where the tangent from one side of the lens assembly 10 meets at a right angle with the first plate 30a of the first housing 30.

In addition, the coupling between the first and second housings 30 and 40 facing each other is achieved by screwing a portion of one of the housings at a right angle to each other and extending through the extended portion. In this case, the extended portion may be formed in either the first housing 30 or the second housing 40.                     

However, one surface of any one housing is equipped with a tripod 70 (see FIG. 5) for changing the direction of the camera. Therefore, it is preferable that the tripod 70 is completely in surface contact with one surface of the housing by preventing the screw 60 used for the coupling from protruding from one surface of the housing coupled to the tripod 70. In this embodiment, the tripod counterpart 71 is in surface contact with the second plate 30b of the first housing 30. Therefore, it is preferable that the coupling between the housings 30 and 40 is made such that the screw 60 or the like does not protrude from the second plate 30b of the first housing 30.

In this embodiment, a portion extending from the second board 30b is in surface contact with the circuit board 20 so that the circuit board 20 positioned on the inner surface of the second board 30b is grounded. It is designed to be.

Therefore, it is necessary to form the first step portion 35 with respect to the second plate 30b so that the circuit board portion 20 is grounded while avoiding interference when combining with the tripod 70. The first stepped part 35 is bent twice at a right angle from the second plate 30b to form a step with the second plate 30b and is in surface contact with the circuit board part 20.

Due to the configuration of the first step part 35, a second coupling part 43 is formed in the first plate 40a of the second housing 40 to be coupled with the first step part 35. The second coupling part 43 extends from the first plate 40a of the second housing 40 at a right angle to correspond to the first step part 35.

Such a configuration is formed in a similar manner to the first plate 30a of the first housing 30 and the second plate 40b of the second housing 40a. In other words, the first coupling part 37 is bent and formed at the edge of the first plate 30a of the first housing 30, and the edge of the second plate 40b of the second housing 40 is bent relative to each other. The second stepped portion 41 is formed to be recessed. The first coupling portion 37 and the second step portion 41 are in surface contact with each other and are coupled through a screw 60 or the like.

The front housing 50 may be provided at the front portion of the lens assembly 10. The front housing 50 is coupled to the first and second housings 30 and 40, respectively, to form a front appearance of the camera.

Hereinafter, the operation of the camera according to the present invention will be described in detail.

First, the process of assembling the camera according to the present invention will be described.

The circuit board unit 20 is substantially rectangular in shape and is disposed on three sides of the lens assembly 10, respectively. At this time, the circuit board 20 is coupled to the fastening boss (not shown) of the lens assembly 10 through a screw 60 or the like in contact with the lens assembly 10.

The lens assembly 10 and the circuit board unit 20 are externally formed by the first housing 30 and the second housing 40 to be mounted on the tripod 70. At this time, each of the depression coupling portion 31 and the extension coupling portion 33 formed on the first plate 30a of the first housing 30 is coupled to two adjacent side surfaces of the lens assembly 10, respectively. Their coupling is made via screws 60.

Due to the recess coupling part 31 and the extension coupling part 33, the role of the conventional sub-housing may be integrated into one housing, and the depression coupling part 31 and the extension coupling part 33 may have a lens. Since the lens assembly 10 is coupled to both sides of the assembly 10, the lens assembly 10 may be stably positioned in the housings 30 and 40. In addition, the depression coupling part 31 and the extension coupling part 33 can reduce the number of housings, thereby reducing the number of processes for screwing.

After that, the first housing 30 and the second housing 40 are connected to each other through both ends of the housings 30 and 40 in contact with each other. That is, the first coupling part 37 formed on the first plate 30a of the first housing 30 and the second step portion 41 formed on the second plate 40b of the second housing 40 are screwed together. The first step part 35 formed on the second plate 30b of the first housing 30 and the second coupling part 43 formed on the first plate 40a of the second housing 40 are screwed together. do.

Therefore, since the stepped portion is formed from the first plate 30a, 40a and the second plate 30b, 40b of the coupling portion of the first housing 30 and the second housing 40, It does not protrude onto the first plates 30a and 40a and the second plates 30b and 40b. Therefore, the tripod counterpart 71 can be completely in surface contact with the second plate 30b of the first housing 30, as shown in FIG. 5, without being affected by the screw head.

The first step part 35 is in surface contact with the circuit board part 20 disposed on the inner surface of the second plate 30b of the first housing 30. Therefore, the overcurrent generated by the circuit board unit 20 can be grounded to the ground.

When the combination of the camera is completed, the camera is installed in the tripod counterpart 71 of FIG. At this time, the second plate 30b of the first housing 30 is coupled to the tripod counterpart 71 through the screw 60. Accordingly, the tripod 70 may set the position and the direction of the camera, and enlarge or reduce a desired image by using the zoom function of the lens assembly.

The front housing 50 may be coupled to the first and second housings 30 and 40 at a point in time in which the camera is coupled, but before the first and second housings 30 and 40 are coupled to each other. Preferably, the lens assembly 10 is fitted to the front surface of the lens assembly 10. At this time, the fitting of the front housing 50 is made by inserting the lens assembly 10 into the through hole formed in the front housing 50.

In the present invention as described above, the tripod counterpart 71 is illustrated to be coupled to the second plate 30b of the first housing 30, but is not limited thereto.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

In the camera according to the present invention as described in detail above, the following effects can be expected.

That is, by depressing and extending one surface of the housing to be coupled to both surfaces of the lens assembly, the number of housings as well as the number of screw couplings can be reduced. Therefore, according to the present invention, the workability is improved and the assembly time of the camera is shortened.                     

In addition, since the screws for coupling between the housings do not protrude to the outer surface of the housing, there is an advantage that the camera can be stably driven on the tripod by being coupled in surface contact with the tripod counterpart.

In addition, the stepped portion for coupling between the housing is formed in the recessed surface contact with the circuit board portion has the effect that the grounding of the circuit board portion more secure.
