Description

A dome camera cable protection device and a dome camera

technical field

The utility model relates to a dome camera cable protection device and a dome camera, belonging to the field of camera monitoring equipment.

Background technique

The main components of the dome camera include an integrated camera, a high-speed stepping motor pan/tilt, and an integrated control chip. The camera is installed on the motor platform and can be rotated under the control of the integrated control chip to achieve the monitoring effect. In order to supply power to the camera and perform signal transmission (input of control signals and output of images), cables must be inserted into the camera.

Fig. 1 shows the schematic structural view of the cable access part, including a bracket 8, a camera 9 rotatably arranged on the bracket 8 through a rotating shaft 6, the camera 9 is fixedly connected to the rotating shaft 6, and a through hole 2 is provided on the rotating shaft 6, and the wire The cable 1 passes through the through hole 2 and is connected with the camera 9 . When the camera 9 rotates, the rotating shaft 6 rotates together with the camera 9, so as to move relative to the cable 1, causing friction between the cable 1 and the inner wall of the rotating shaft 6. Since the rotating shaft 6 is usually made of aluminum or aluminum alloy, the rotation of the rotating shaft 6 The friction coefficient is large, so the cable 1 is easily broken when the cable 1 rubs against the rotating shaft 6, so it is very necessary to install a cable protection device in order to improve the service life of the dome camera.

In the prior art, the cable 1 is protected by fixing the rubber protection member 3 on the rotating shaft 6. The rubber protection member 3 has an isolation part located in the through hole 2, and the cable 1 and the cable 1 are connected by the isolation part of the rubber protection member 3. The inner walls of the through holes 2 are isolated from each other. During use, when the camera 9 rotates, the rotating shaft 6 and the camera 9 rotate together. Since the rubber protection part 3 is fixedly arranged on the rotating shaft 6, the rubber protection part 3 will follow the rotating shaft 6 and rotate together, thereby causing friction with the cable 1 . This arrangement converts the friction between the cable 1 and the rotating shaft 6 into the friction between the cable 1 and the rubber protection member 3 . Since the friction coefficient of the rubber protection member 3 is smaller than the friction coefficient of the rotating shaft 6, the damage to the cable 1 can be reduced to a certain extent. However, in a low temperature environment (below -40°C), the cable 1 The insulation layer of the cable will become hard and brittle, and its flexibility will be reduced, and slight friction will also cause damage to the cable 1. Therefore, the cable protection device in the prior art cannot protect the cable 1 in a low temperature environment.
