Description

Technical Field

[0001] The utility model belongs to the field of stage lights, and particularly relates to a wire harness guiding device for a zoom stage light. Background Art

[0002] As an important light source for stage lights, the LED light source is widely used in stage lights due to its many advantages such as high luminous efficiency, good combined rendering effect, energy conservation and environmental protection, and long service life. Many LED stage lights maximize the addition of LED auxiliary combined light sources near the light outlet of the lamp. Especially for zoom stage lights, the LED auxiliary combined light source moves with the movement of the zoom component, and different combined effects can be achieved to meet the needs of the stage or performance. However, during the zooming process of the zoom stage light, the wire harness (multiple cables) of the auxiliary light source needs to move back and forth frequently with the zoom component. To avoid the zoom component pulling on the wire harness, the wire harness needs to reserve a relatively long length. However, when the zoom component is at the nearest end, the reserved wire harness will bend and gather. When the zoom component moves back and forth frequently, the cables in the wire harness are easily damaged.

[0003] In the prior art, such as the patent document with the publication number CN216281190U, a zoom system for a stage light lens is disclosed. By setting an O-ring at the connection between the focusing nut and the lens bracket, the problem of jamming caused by asynchronous movement between multiple focusing nuts is avoided. However, when the zoom nut is at the nearest end, the wire harness will still bend and gather, and when the zoom nut moves back and forth frequently, the cables in the wire harness are easily damaged due to interference with other components. Summary of the Invention

[0004] Aiming at the problems in the prior art, the utility model provides a wire harness guiding device for a zoom stage light. By fixing part of the cables with a downward-extending zoom cable protector, the bendable length of the cables is shortened, and the deformed cables are driven by the zoom cable protector to swing up and down, preventing the cables from being damaged due to excessive bending and interference with other components.

[0005] The utility model is realized as follows: A wire harness guiding device for a zoom stage light, the zoom stage light includes a reciprocatingly moving lamp auxiliary light source module. The wire harness guiding device is installed on the auxiliary light source module and includes an auxiliary light source, a substrate, and a wire guiding component. The auxiliary light source is installed on the substrate. The wire guiding component includes a cable. One end of the cable is connected to an external power supply, and the other end is connected to the auxiliary light source. It further includes a zoom cable protector installed on the substrate and extending downward. The zoom cable protector is used to fix part of the cables, shortening the bendable and deformable length of the cables. At the same time, it also reduces the highest point after the cables are straightened, reduces the movement space required for the cables to bend and deform, and reduces the risk of interference caused by the bending and deformation of the cables.

[0006] The cable includes a first fixing part, a second fixing part, and a movable part that are connected end to end in sequence. The first fixing part is fixedly connected to the substrate, the second fixing part is fixedly connected to the zoom cable protector, and one end of the movable part connected to the second fixing part swings up and down as the second fixing part moves up and down. The movable part has a margin for the cable to move. When the zoom cable protector rises, it drives one end of the movable part connected to the second fixing part to swing upward, and at the same time, the other end moves toward the direction of the zoom cable protector, preventing the movable part from being pulled during the swinging process; when the zoom cable protector descends, it drives one end of the movable part connected to the second fixing part to swing downward, and at the same time, the other end moves away from the direction of the zoom cable protector, preventing the cable from being bent and deformed, thereby causing interference and damage to the cable and other components, and improving the safety of the cable.

[0007] Preferably, the zoom cable protector is L-shaped and includes a cable protection part and a mounting part that are perpendicular to each other. Elastic units are respectively sleeved in the cable slot grooves provided on the circumferences of both ends of the cable protection part. The mounting part is used to fix the zoom cable protector so that the zoom cable protector moves with the substrate. The elastic unit is used to fix the second fixing part to the cable protection part. At the same time, the elastic unit can undergo elastic deformation and can be compatible with cables of different specifications, improving the compatibility of the cable protection part.

[0008] Specifically, the zoom cable protector is an injection molded part and is integrally formed by injection molding, which can reduce the cost of the zoom cable protector; both sides of the zoom cable protector extend in the extending direction of the mounting part to form a guiding groove adapted to the cable, and the guiding groove is used to assist in fixing the second fixing part, making the fixing of the second fixing part more reliable.

[0009] Alternatively, the zoom cable protector is a sheet metal part and is integrally formed by bending.

[0010] Preferably, a transfer board that is electrically connected to both the cable and the auxiliary light source is provided on the substrate, and the auxiliary light source is installed on the top of the transfer board; a transfer interface corresponding to the cable is also provided on the circumference of the transfer board, and a transfer joint adapted to the transfer interface is provided at one end of the cable connected to the transfer board, and the transfer joint is inserted into the transfer interface. The transfer board and the transfer joint form a detachable plug-in mechanism between the cable and the auxiliary light source. On the one hand, the cable and the auxiliary light source can be installed separately, improving the installation convenience of the cable and the auxiliary light source; on the other hand, it is convenient to replace and maintain the auxiliary light source or the cable when they are damaged, improving the maintenance convenience of the cable and the auxiliary light source.

[0011] Specifically, through holes corresponding to the adapter are provided on the substrate, and the cable passes through the through holes from bottom to top in front of the adapter. Since the light-emitting surface of the auxiliary light source cannot be blocked, the auxiliary light source is installed on the top of the substrate, and the cable is located inside the zoom stage light. The cable needs to pass through or bypass the substrate to be connected to the auxiliary light source. The through holes provide an effective way for the cable to pass through the substrate, avoiding the increase in the cable length caused by the cable bypassing the substrate, thereby reducing the risk of interference between the cable and other components.

[0012] Specifically, a fixing plate adapted to the cable is further provided at the through hole, and the cable located at the through hole is fixed on the fixing plate. The fixing plate is used to fix the cable at the through hole, preventing the cable in the through hole from shaking when the substrate moves in a zoom manner and rubbing against the edge of the through hole, resulting in damage to the cable, and improving the safety of the cable.

[0013] Preferably, a plurality of support columns are provided between the adapter plate and the substrate. One end of each support column abuts against the substrate, and the other end abuts against the adapter plate. The support columns form an installation space between the adapter plate and the substrate. When the adapter is inserted into the adapter plate, there is a gap between the adapter and the substrate, preventing the plug from being stuck due to dimensional errors during insertion.

[0014] Preferably, a protective layer is sleeved outside the cable. The protective layer is a soft sleeve or a flannel tape, which is used to protect the cable and increase the hardness of the cable, preventing the cable from bending and deforming when the zoom cable protection member descends.

[0015] Preferably, the swing angle range of the movable part is 0 - 60°. The swing angle is used to limit the highest point of the upward swing of the movable part, further reducing the required movement space when the cable swings, and further reducing the risk of interference between the cable and other components.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] Embodiment 1

[0029] As Figures 1-6As shown, a wire harness device for a zoom stage light. The zoom stage light 1 includes an auxiliary light source module that reciprocates. The wire harness device 11 is installed on the auxiliary light source module and includes an auxiliary light source, a substrate 111, and a wire assembly 112. The auxiliary light source is installed on the substrate 111. The wire assembly 112 includes a cable. One end of the cable is connected to an external power supply, and the other end is connected to the auxiliary light source.

[0030] In this embodiment, a transfer board 113 that is electrically connected to both the cable and the auxiliary light source is provided on the substrate 111. The auxiliary light source is installed on the top of the transfer board 113. A transfer interface corresponding to the cable is also provided on the periphery of the transfer board 113. One end of the cable connected to the transfer board 113 is provided with a connector 1126 that is adapted to the transfer interface. The connector 1126 is inserted into the transfer interface. The transfer board 113 and the connector 1126 form a detachable plug-in mechanism between the cable and the auxiliary light source. On the one hand, the cable and the auxiliary light source can be installed separately, improving the installation convenience of the cable and the auxiliary light source. On the other hand, it is convenient to replace and maintain the auxiliary light source or the cable when they are damaged, improving the maintenance convenience of the cable and the auxiliary light source.

[0031] Specifically, a through hole 1111 corresponding to the connector 1126 is provided on the substrate 111. The cable in front of the connector 1126 passes through the through hole 1111 from bottom to top. Since the light-emitting surface of the auxiliary light source cannot be blocked, the auxiliary light source is installed on the top of the substrate 111, and the cable is located inside the zoom stage light 1. The cable needs to pass through or bypass the substrate 111 to be connected to the auxiliary light source. The through hole 1111 provides an effective way for the cable to pass through the substrate 111, avoiding the risk of increasing the cable length to bypass the substrate 111 and thus increasing the interference risk between the cable and other components.

[0032] Specifically, a fixing plate 1112 adapted to the cable is also provided at the through hole 1111. The cable at the through hole 1111 is fixed to the fixing plate 1112. The fixing plate 1112 is used to fix the cable at the through hole 1111, preventing the cable in the through hole 1111 from shaking when the substrate 111 moves in a zoom manner and rubbing against the edge of the through hole 1111, resulting in damage to the cable and improving the safety of the cable.

[0033] In this embodiment, a plurality of support columns 114 are provided between the adapter board 113 and the substrate 111. One end of each support column 114 abuts against the substrate 111, and the other end abuts against the adapter board 113. The support columns 114 form an installation space between the adapter board 113 and the substrate 111. When the adapter 1126 is inserted into the adapter board 113, there is a gap between the adapter 1126 and the substrate 111, preventing the plug from jamming due to dimensional errors during insertion.

[0034] It further includes a zoom cable protector 1121, which is installed on the substrate 111 and extends downward; the zoom cable protector 1121 is used to fix part of the cable, shortening the length of the cable that can be bent and deformed. At the same time, it also reduces the highest point after the cable is straightened, reduces the movement space required for the cable to bend and deform, and reduces the risk of interference caused by the cable bending and deforming.

[0035] The cable includes a first fixing portion 1123, a second fixing portion 1124, and a movable portion 1125 that are connected end to end in sequence. The first fixing portion 1123 is fixedly connected to the substrate 111, the second fixing portion 1124 is fixedly connected to the zoom cable protector 1121, and one end of the movable portion 1125 connected to the second fixing portion 1124 swings up and down as the second fixing portion 1124 moves up and down. The movable portion 1125 has a margin for the cable to move. When the zoom cable protector 1121 rises, it drives one end of the movable portion 1125 connected to the second fixing portion 1124 to swing upward, and at the same time the other end moves toward the direction of the zoom cable protector 1121, preventing the movable portion 1125 from being pulled during the swinging process; when the zoom cable protector 1121 descends, it drives one end of the movable portion 1125 connected to the second fixing portion 1124 to swing downward, and at the same time the other end moves away from the direction of the zoom cable protector 1121, preventing the cable from bending and deforming, thereby causing the cable to interfere and be damaged by other components, and improving the safety of the cable.

[0036] In this embodiment, the zoom cable protector 1121 is L-shaped, including a cable protection portion 11211 and a mounting portion 11212 that are perpendicular to each other. Elastic grooves 11213 are respectively provided on the circumferences at both ends of the cable protection portion 11211, and elastic units 1122 are sleeved in the elastic grooves 11213. The mounting portion 11212 is used to fix the zoom cable protector 1121, enabling the zoom cable protector 1121 to move with the substrate 111. The elastic units 1122 are used to fix the second fixing portion 1124 to the cable protection portion 11211. At the same time, the elastic units 1122 can undergo elastic deformation, can be compatible with cables of different specifications, and improve the compatibility of the cable protection portion 11211.

[0037] Specifically, the zoom cable protector 1121 is an injection molded part, which is integrally formed by injection molding, and can reduce the cost of the zoom cable protector 1121. The two sides of the zoom cable protector 1121 extend in the extending direction of the mounting portion 11212 to form a guiding groove 11214 adapted to the cable. The guiding groove 11214 is used to assist in fixing the second fixing portion 1124, making the fixing of the second fixing portion 1124 more reliable.

[0038] In this embodiment, a protective layer is sleeved outside the cable. The protective layer is a soft sleeve or a flannel tape, which is used to protect the cable and increase the hardness of the cable, and prevent the cable from being bent and deformed when the zoom cable protector 1121 descends.

[0039] In this embodiment, the swinging angle range of the movable portion 1125 is 0-60°. The swinging angle is used to limit the highest point of the upward swing of the movable portion 1125, further reducing the required moving space when the cable swings, and further reducing the risk of interference between the cable and other components.

For the features not explained in this embodiment, the explanations in Embodiment 1 are adopted and will not be elaborated here. The difference between this embodiment and Embodiment 1 lies in:

[0042] The zoom cable protector 1121 is a sheet metal part, which is integrally formed by bending. Compared with the injection molded part, the sheet metal part has better thermal stability on the one hand, preventing the heat generated when the auxiliary light source works from being transferred to the zoom cable protector 1121 and causing the zoom cable protector 1121 to deform due to heat; on the other hand, it has better durability and can extend the service life of the zoom cable protector 1121.
