Here, the lens assembly 150 is composed of at least one lens, the number of lenses constituting the lens assembly can be arbitrarily adjusted. In this way, a plurality of lenses constituting the lens assembly are assembled such that the optical axes of each lens coincide.

The lens unit printed circuit board 155 is formed on the optical axis of the lens assembly 150 in the rotate body 140. In detail, an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) is mounted at a position corresponding to the lens assembly 150 on the lens unit printed circuit board 155, through the lens assembly 150. The incident light is converted into an electrical signal. In addition, the lens unit printed circuit board 155 converts an analog signal output from an image sensor into a digital signal and adjusts amplitude, etc., a CDS-ADC (Correlation Double Sampler and Analog-to-Digital Converter) circuit and a DSP (Digital). signal processor) may be further provided.

It will be appreciated that the present invention can be applied to any surveillance camera having an internal structure that they can interfere with.

Meanwhile, the lens unit printed circuit board 155 and the main printed circuit board 115 are connected to each other by a cable 180. In detail, the plurality of cables connected to the lens unit printed circuit board 155 may be bundled together with an adhesive tape and collected in one bundle. That is, although only two or three cables are formed in FIG. 2, the cable 180 may be assumed to be a cable bundle in which a plurality of cables are collected. The cover rear 160 and the cap rear 170 are coupled to the rear surface of the lens assembly 150 and the rotate body 140 to connect the lens unit printed circuit board 155 and the main printed circuit board 115. The cable 180 is not twisted and exposed to the outside.

In other words, the surveillance camera 100 according to an embodiment of the present invention uses a simple mechanism structure such as the cover rear 160 and the cap rear 170 to prevent the cable twisted and the problem that the cable is caught on other parts. At the same time it is characterized in that the cable is not exposed to the outside.

In detail, dome type surveillance cameras are surveillance cameras in which a camera is installed in a hemispherical dome, and has been developed to make the surveillance cameras less visible and to facilitate the installation of the surveillance cameras. In such a dome type surveillance camera, the lens assembly is located inside the hemispherical dome, and the main printed circuit board is generally provided at the base side in a form separated from the lens assembly to secure the largest area possible. to be. In this case, the lens assembly (and the lens unit printed circuit board coupled thereto) and the main printed circuit board may be connected through a cable.

However, as surveillance cameras have evolved from analog models to network models and the number of pixels in the camera has increased, the cable connecting the lens assembly and the main printed circuit board has increased in number of strands and has become generally thick. In addition, while the specifications of the surveillance cameras pursue high specifications (increasing the size of the lens assembly, increasing the thickness of the cable, increasing the size of the printed circuit board), the overall set size is tending to be the same or smaller than the conventional one to enhance the competitiveness.

Therefore, the cable is twisted or entangled inside the surveillance camera (or a problem that interferes with rotation due to other components), and the cable is exposed to the naked eye from the outside of the product. In order to solve this problem, the following methods have been developed.

First, a method was developed to use an additional structure that centers the cable to prevent it from twisting. On the other hand, the following method is used to prevent the exposure of the cable to the outside. First, a method was developed using a smoked dome that painted a dome cover dark. However, in this case, since the camera image is dark, there is a problem that can not be applied to a high-pixel surveillance camera. In addition, by installing an additional structure (ie cover dome in) to cover the cable inside, it was developed to cover the portion other than the movement trajectory of the lens to the additional structure. In this case, however, there is a problem that it is not easy to place additional parts in an increasingly smaller set, and it is not easier to add a part for preventing cable twist.

In order to solve such a problem, the surveillance camera 100 according to an embodiment of the present invention, characterized in that the cable is prevented from being exposed to the outside at the same time to prevent the cable twist by using a simple mechanism structure. . This will be described in more detail below.

3 is a rear perspective view of the cover rear of the surveillance camera of FIG. 1, FIG. 4 is a rear perspective view of a cap rear of the surveillance camera of FIG. 1, and FIG. 5 is a cover of the surveillance camera of FIG. 1. This is a perspective view showing a state in which the rear and the cap rear are combined.

3, 4 and 5, the cover rear (160) of the surveillance camera according to an embodiment of the present invention is a cover rear body 161, cable guide hole 162, coupling hole ( 163 and heat dissipation holes 164. The cap rear 170 includes a cap rear body 171, a cable receiving groove 172, and a coupling protrusion 173.

In detail, the cover rear main body 161 is formed so that the cross section may form an arc, and is formed in the shape of a hollow basket as a whole. In addition, a cable lead-out hole 162 may be formed at the center of the cover rear main body 161. One end of the cable 180 connected to the lens unit printed circuit board 155 through the cable lead-out hole 162 may exit the outside. In this case, the cable lead-out hole 162 is formed in a shape in which the center portion is extended in a circular shape in a rectangular shape, so that the coupling protrusion 172 of the cap rear 170 to be described later can be fitted. In this way, the cable lead-out hole 162 through which the other end of the cable 180 connected to the lens printed circuit board 155 is formed to be formed outside is formed, thereby minimizing interference between the cable 180 and other components and thus the cable ( 180) to prevent jamming or twisting caused by interference with other parts.

On the other hand, the coupling hole 163 is formed on at least one side of the end of the cover rear body 161. The cover rear 160 may be fixedly coupled to the lens assembly 150 (or the rotate body 140 to which the lens assembly 150 is coupled) through pin coupling or bolt coupling through the coupling hole 163. Accordingly, the cover rear 160 is rotated together when the lens assembly 150 (or the rotate body 140 to which the lens assembly 150 is coupled) rotates.

Meanwhile, one or more heat dissipation holes 164 may be further formed in the cover rear body 161 along the arc direction. Through such a heat dissipation hole 164, a space in which the air cooling the lens assembly 150 is discharged to the outside may be provided.

Meanwhile, the cap rear 170 includes a cap rear body 171, a cable receiving groove 172, and a coupling protrusion 173.

In detail, the cap rear body 171 may also be formed such that its cross section is arced. In addition, a cable receiving groove 172 may be formed in the central portion of the cap rear body 171. The cable 180 exiting to the outside through the cable lead-out hole 162 is fitted into the cable receiving groove 172. As the cable 180 is inserted into the cable receiving groove 172 as described above, the direction of the cable 180 is guided toward the base 110 and the main printed circuit board 115 accommodated therein. That is, if the cable 180 is formed long to smoothly rotate the rotate body 140, interference with other components may occur, and if the cable 180 is formed short to suppress such interference, the rotate body 140 may be formed. There is a problem in that the range of rotation is limited. Therefore, in the present invention, the cable receiving groove 172 is formed in the cap rear 170 to guide the extension direction of the cable 180, so that the withdrawal direction of the cable 180 is fixed even if the rotator body 140 rotates in any direction. In order to prevent the jamming of the cable 180 without limiting the rotation range of the rotate body 140.

On the other hand, the coupling protrusion 173 is formed in substantially the same shape as the cable lead-out hole 162 of the cover rear body 161 described above, the size may be the same or slightly smaller than the cable lead-out hole 162. . Therefore, the coupling protrusion 173 is fitted to the cable guide hole 162 in a snap-fit form, and once the coupling protrusion 173 is fitted to the cable guide hole 162, the coupling protrusion 173 is fixed. The coupling protrusion 173 is not detached from the cable lead-out hole 162 unless the coupling protrusion 173 is elastically deformed by a force higher than that.

In addition, when the engaging projection 173 is fitted in the snap-fit (snap-fit) form to the cable guide hole 162, the cover rear 160 and the cap rear 170 can be rotated relative to each other. Done. That is, in a state in which one side of the cover rear 160 and the cap rear 170 are fixed, the other side is rotatable.

Thus, even when the cover rear 160 rotates with the lens assembly 150 (or the rotate body 140 to which the lens assembly 150 is coupled), the cap rear 170 is not connected to the cable receiving groove 172. 180) the direction of the cable 180 to pass along the shortest connection path, as a result of the direction of its own, even if it does not rotate or rotates relatively less than the amount of rotation of the cover rear, and consequently the cable 180 This twist is prevented. Furthermore, such a cap rear 170 has a cable 180 fitted therein, while receiving the cable 180 therein so that the cable 180 is not visible from the outside, thereby preventing exposure of the cable 180. By preventing it, the aesthetics of the appearance of the surveillance camera 100 can be improved.

In the above-described embodiments of the present invention, the monitoring camera has a three-axis structure of pan, tilt, and rotate rotation, but the spirit of the present invention is not limited thereto. Those skilled in the art will appreciate that the present invention can be applied to any surveillance camera having an internal structure which may interfere with cables and other components connected to the control circuit board during rotational operation.

In the present specification, the present invention has been described with reference to limited embodiments, but various embodiments are possible within the scope of the present invention. In addition, although not described, equivalent means will also be referred to as incorporated in the present invention. Therefore, the true scope of the present invention will be defined by the claims below.
