Description

Technical Field

[0001] This utility model relates to the field of communication harness technology, specifically a waterproof communication harness. Background Technology

[0002] Communication harnesses are used in new energy vehicles to enable data transmission and communication between various systems within the vehicle. A communication harness is a harness that integrates multiple wires and communication lines to connect various electronic control units inside the vehicle. Communication harnesses can connect to various subsystems such as the motor control system, battery management system, charging system, and in-vehicle entertainment system.

[0003] The prior art patent document with publication number CN222281648U provides a waterproof communication harness, including a harness body, which is connected to an external device through a sleeve mechanism. The sleeve mechanism has an inner ring block inside, and a connecting mechanism is located above the inner ring block. When connecting through the sleeve mechanism, the connecting mechanism can be inserted into the device more smoothly, making the harness connection more convenient and stable. When the harness is connected, the sleeve mechanism moves to one side to insert the connecting mechanism into the device. When the sleeve mechanism moves, the limiting block will contact the limiting plate of the connecting mechanism. The sealing structure on the limiting block and the limiting plate improves the sealing between the sleeve mechanism and the connecting mechanism, effectively preventing water penetration from affecting the harness.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the stability of the sleeve mechanism is insufficient, and it is easy to loosen, which leads to a decrease in sealing performance and affects the waterproof effect; secondly, the stability of the device during use is not good enough and needs to be improved. In view of this, we propose a waterproof communication harness. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of a waterproof communication harness, including:

[0035] Please see Figures 1-5This embodiment of a waterproof communication harness includes a protective jacket 1, with the inner circumference of the protective jacket 1 covering the harness body 2. A plug 3 is fixed to one end of the harness body 2. A waterproof component 4 is fixed to the outer circumference of the protective jacket 1. The waterproof component 4 includes a fixing cylinder 401, with multiple springs 402 fixed to the inner wall of the fixing cylinder 401. A movable cylinder 403 is fixed to the other end of each spring 402. A threaded sleeve 404 is slidably connected to the outer circumference of the protective jacket 1. A first sealing ring 405 is fixed to one end of the threaded sleeve 404, and a second sealing ring 406 is fixed to the other end of the inner circumference of the threaded sleeve 404. A third sealing ring 407 is fixedly provided, and a limiting ring 408 is fixedly provided at one end of the outer circumference of the protective sleeve 1. A limiting component 5 is slidably connected to the outer circumference of the fixed cylinder 401. The threaded sleeve 404 is connected to the device by rotating it. The plug 3 is inserted into the device. The spring 402 drives the moving cylinder 403 to move, thereby causing the threaded sleeve 404 to drive the third sealing ring 407 to move and abut against the limiting ring 408, preventing water from seeping in along the outer circumference of the protective sleeve 1. The first sealing ring 405 prevents water from entering from the gap between the threaded sleeve 404 and the device. The second sealing ring 406 further enhances the sealing performance and improves the waterproof effect.

[0036] It is worth noting that, in order to prevent the fixed cylinder 401 from tipping over, the limiting component 5 specifically includes an insert plate 501. A handle 502 is fixedly provided on the outer circumference of the insert plate 501. A limiting groove 503 is opened on the side wall of the insert plate 501. A limiting block 504 is fixedly provided on the outer circumference of the fixed cylinder 401. A slot 505 is opened on the outer circumference of the moving cylinder 403. Pulling the moving cylinder 403 to move it into the fixed cylinder 401, and pushing the handle 502 to move the insert plate 501 to insert it into the slot 505, makes it easier to lock the moving cylinder 403 and improves stability. When it is necessary to connect the plug 3, pulling the handle 502 to move the insert plate 501 away from the slot 505, and limiting the limiting groove 503 by the limiting block 504 to prevent the insert plate 501 from falling off.

[0037] Next, to improve sealing performance, specifically, the first sealing ring 405, the second sealing ring 406, and the third sealing ring 407 are all made of EPDM rubber. The threads on the inner circumference of the threaded sleeve 404 are close to the end of the first sealing ring 405. EPDM rubber is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene. Its main chain is composed of chemically stable saturated hydrocarbons, and it only contains unsaturated double bonds in the side chains. Therefore, it has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance, and can be widely used in automotive parts, waterproof building materials, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals, and other fields.

[0038] Meanwhile, to prevent water from seeping in, specifically, the inner diameter of the third sealing ring 407 matches the diameter of the wire harness body 2, and the diameter of the limiting ring 408 matches the inner diameter of the threaded sleeve 404. Through the third sealing ring 407, which matches the diameter of the wire harness body 2, water is prevented from flowing in from the gap between the third sealing ring 407 and the outer circumference of the wire harness body 2, thus avoiding damage to the plug 3.

[0039] Furthermore, in order to prevent the movable cylinder 403 from swaying, specifically, the cross-section of the fixed cylinder 401 is L-shaped, and the size of the movable cylinder 403 matches the size of the inner cavity of the fixed cylinder 401. By using a movable cylinder 403 that matches the size of the inner cavity of the fixed cylinder 401, it is easier to make the movable cylinder 403 move more smoothly.

[0040] It is worth noting that, in order to improve stability, specifically, the size and position of the limiting groove 503 are matched with the size and position of the limiting block 504, and the size and position of the insert plate 501 are matched with the size and position of the slot 505. By using the insert plate 501, which is matched with the size and position of the slot 505, the threaded sleeve 404 can be made more stable.

[0041] Finally, to facilitate use by staff, the threaded sleeve 404 is specifically provided with multiple protrusions 6 on its outer circumference. The multiple protrusions 6 are arranged in a ring array, which increases friction and facilitates rotation by staff.

[0042] Combination Figures 1-5 The waterproof communication harness of this embodiment is used in the following specific way:

[0043] 1: When this device is needed for use as a waterproof communication harness, rotate the threaded sleeve 404 to connect with the device threaded connection, insert the plug 3 into the device, and the spring force of the spring 402 causes the moving cylinder 403 to move, which in turn moves the threaded sleeve 404, thereby causing the third sealing ring 407 to move and abut against the limiting ring 408, and the first sealing ring 405 to move and abut against the device.

[0044] 2: Pull the movable cylinder 403 into the fixed cylinder 401, push the insert plate 501 to move and insert it into the slot 505 to lock the movable cylinder 403. When the plug 3 needs to be connected, pull the handle 502 to move the insert plate 501 out of the slot 505.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
