Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera dynamic line. Background Art

[0002] The main function of the camera dynamic cable is to transmit the images or video data captured by the camera to the corresponding equipment, such as video recorders, computers, monitors, etc., so that users can view the monitoring screen. It is used to transmit the signals for controlling the camera, such as the pan / tilt control signal, to realize the camera's up and down, left and right rotation, zoom, focus and other operations. In some cases, the cable can also provide power support for the camera, especially for some cameras that require external power supply, such as PoE cameras. The same cable transmits both data and power, simplifying the wiring.

[0003] In the prior art, the camera dynamic line is a separate data transmission line that directly connects the camera to the external receiving device. When transporting the camera dynamic line, the camera dynamic line is wound on a reel for transportation.

[0004] There are some problems. There are no effective protection measures for the camera dynamic line. When the use scene shakes, the shaking will directly act on the data transmission line, and the data transmission line will inevitably be damaged. When transporting the camera dynamic line, the external road is often not always flat. When passing through bumpy sections, the joints of the camera dynamic line are prone to collision with the outside, causing damage to the joints of the camera dynamic line. For this reason, we propose a camera dynamic line. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a camera dynamic line, which can indirectly improve the resistance of the camera dynamic line by isolating external shaking to avoid its direct effect on the wiring harness, and at the same time prevent the joints of the camera dynamic line from being damaged by external collisions during transportation, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a camera dynamic line, comprising a wire harness, wherein both the front and rear ends of the wire harness are equipped with connectors, and further comprising a tensile mechanism;

[0007] Anti-tensile mechanism: It includes an anti-tensile joint, an installation head, an anti-tensile cable and an insulating sleeve. The anti-tensile joints are equipped with installation heads on the opposite outer sides. A anti-tensile cable is provided between the two anti-tensile joints. An insulating sleeve is provided between the two anti-tensile joints. The anti-tensile cable and the insulating sleeve are installed in cooperation. The wiring harness is arranged inside the insulating sleeve. By isolating the external shaking so that it does not directly act on the wiring harness, the dynamic line resistance performance of the camera is indirectly improved, and the joint is prevented from being damaged by external collision during the transportation of the dynamic line of the camera.

[0008] Furthermore, the insulating sleeve includes an outer layer and an inner layer, and the outer layer and the inner layer are both arranged between the outer arc surfaces of the relative inner ends of the two tensile joints. The tensile cable is located between the outer layer and the inner layer. When shaking occurs, the main force is transmitted to the tensile cable.

[0009] Furthermore, the outer arc surface of the wiring harness is wrapped with an insulating layer to facilitate insulation.

[0010] Furthermore, the tensile mechanism also includes a sliding barrel and a sliding plate. Sliding barrels are provided at both ends of the inner arc surface of the inner layer, and sliding plates are provided at both ends of the outer arc surface of the insulating layer. The sliding plates are slidably connected to the front and rear adjacent sliding barrels to prevent damage to the wiring harness caused by large external shaking.

[0011] Furthermore, the tensile mechanism also includes a mounting ring, a rubber strip and a plug. The middle part of the outer arc surface of the mounting head is provided with a mounting ring, the right end of the outer arc surface of the mounting ring is provided with a rubber strip, and the right end of the rubber strip is provided with a plug to prevent the joint of the dynamic line of this camera from being damaged during transportation.

[0012] Furthermore, through holes are provided in the middle of the tensile joint and the mounting head to facilitate joint connection.

[0013] Furthermore, the plugs are all rubber plugs, and the diameters of the two plugs' opposite outer ends are equal to the diameter of the through hole in the middle of the adjacent mounting head on the left, and the diameters of the opposite inner ends of the plugs are twice the diameter of the through hole in the middle of the adjacent mounting head on the left. Due to the ductility of rubber, the plugs fit tightly against the through hole in the middle of the mounting head.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the camera dynamic line has the following advantages:

[0015] 1. Through the cooperation of the insulating sleeve and the tensile cable, when the working scene shakes, the high elasticity of the polyurethane material of the insulating sleeve can provide better protection during stretching and reduce damage to the internal conductor. At the same time, the internal steel wire of the tensile cable resists tension, and the external shaking does not directly act on the wiring harness, which indirectly improves the dynamic line resistance performance of the camera.

[0016] 2. Use a plug to block the through hole in the middle of the mounting head to prevent the connector from being damaged by external collision during the dynamic line transportation of the camera. BRIEF DESCRIPTION OF THE DRAWINGS

It also includes a tensile mechanism 2;

[0026] Tensile mechanism 2: It includes a tensile joint 21, a mounting head 22, a tensile cable 26 and an insulating sleeve 27. The mounting head 22 is installed on the opposite outer side of the tensile joint 21 (the edges of the tensile joint 21 and the mounting head 22 are provided with evenly distributed threaded holes, and workers can firmly install the tensile joint 21 and the mounting head 22 with bolts). A through hole is provided in the middle of the tensile joint 21 and the mounting head 22. A tensile cable 26 is provided between the two tensile joints 21 (the tensile cable 26 is a steel wire tensile cable). An insulating sleeve 27 is provided between the two tensile joints 21. The tensile cable 26 and the insulating sleeve 27 are installed together. The wiring harness 1 is arranged inside the insulating sleeve 27. The insulating sleeve 27 includes an outer layer 271 and an inner layer 272. The outer layer 271 and the inner layer 27 2 are both sleeved between the outer arc surfaces of the opposite inner ends of the two tensile joints 21 (the outer layer 271 and the inner layer 272 of the insulating sleeve 27 are both polyurethane layers), the tensile cable 26 is located between the outer layer 271 and the inner layer 272, the tensile mechanism 2 also includes a slide barrel 28 and a slide plate 29, the inner arc surface of the inner layer 272 is provided with a slide barrel 28 at both ends, the outer arc surface of the insulating layer 4 is provided with a slide plate 29 at both ends, the slide plate 29 is slidably connected to the front and rear adjacent slide barrels 28, the tensile mechanism 2 also includes a mounting ring 23, a rubber strip 24 and a plug 25, the middle part of the outer arc surface of the mounting head 22 is sleeved with a mounting ring 23, the right end of the outer arc surface of the mounting ring 23 is provided with a rubber strip 24, the right end of the rubber strip 24 is provided with a plug 25, the plug 25 is a rubber plug, and the two plugs 25 are opposite to the outer The diameters of the two ends are equal to the diameter of the through hole in the middle of the adjacent mounting head 22 on the left, and the diameters of the relatively inner ends of the plug 25 are twice the diameter of the through hole in the middle of the adjacent mounting head 22 on the left. The worker removes the bolts connecting the mounting head 22 to the tensile joint 21, and then installs the mounting head 22 to the camera and the display that receives the camera image, and then firmly connects the two connectors 3 to the camera and the display. At this time, the wiring harness 1 connects the camera and the display (the insulating layer 4 provides good insulation), and then uses the external bolts to connect the tensile joint 21 to the mounting head 22. When connecting, the worker can use a sealing ring between the tensile joint 21 and the mounting head 22. At this time, if the working scene shakes, the insulating sleeve 27 is made of high elastic polyurethane material. , can provide better protection during stretching, reduce damage to the internal conductor, and at the same time, the shaking force is transmitted to the tensile cable 26. When the steel wire in the tensile cable 26 is subjected to the pulling force of shaking, the distance between the atoms inside the gas will change slightly. This change will cause the change of the binding force between atoms. Within a certain range, the attraction between atoms will increase with the increase of distance, thereby producing the effect of resisting tension. The external shaking does not directly act on the harness 1, which indirectly improves the resistance performance of the camera dynamic line. At this time, the sliding barrel 28 on the inner layer 272 slides with the sliding disc 29. In addition, during the transportation of the camera dynamic line before installation, the worker can insert the plug 25 into the inside of the through hole in the middle of the adjacent installation head 22, and fold the rubber strip 24.Place the plug 25 close to the mounting head 22, and then forcefully insert the end of the plug 25 with the same diameter as the through-hole into the through-hole. Due to the ductility of the rubber, the plug 25 fits tightly against the through-hole in the middle of the mounting head 22, preventing the connector 3 from being damaged during transportation. This improves the dynamic linear resistance performance of the camera while also preventing damage to the connector 3 during transportation.

[0027] The working principle of a camera dynamic line provided by the present invention is as follows: first, the worker removes the bolts connecting the mounting head 22 to the tensile joint 21, and then installs the mounting head 22 to the camera and the display that receives the camera shooting picture, and then firmly connects the two connectors 3 corresponding to the camera and the display. At this time, the wiring harness 1 connects the camera and the display (the insulating layer 4 provides good insulation), and then uses external bolts to connect the tensile joint 21 to the mounting head 22. When connecting, the worker can use a sealing ring to pad between the tensile joint 21 and the mounting head 22. At this time, if the working scene shakes, the high elasticity of the polyurethane material of the insulating sleeve 27 can provide better protection during stretching, reduce damage to the internal conductor, and at the same time, the shaking force is transmitted to the tensile cable 26, the tensile cable 2 When the steel wire in 6 is subjected to the pulling force of shaking, the distance between the atoms inside the gas will change slightly. This change will cause the binding force between atoms to change. Within a certain range, the attraction between atoms will increase with the increase of distance, thereby producing the effect of resisting tension. The external sliding does not directly act on the harness 1, which indirectly improves the resistance of the camera dynamic line. In addition, during the transportation of the camera dynamic line before installation, the worker can insert the plug 25 into the inside of the through hole in the middle of the adjacent installation head 22, and by folding the rubber strip 24, move the plug 25 close to the installation head 22, and then force the end of the plug 25 with the same diameter as the through hole into the through hole. Due to the ductility of the rubber, the plug 25 fits tightly with the through hole in the middle of the installation head 22 to prevent the joint 3 from being damaged during transportation.
