Description

Technical Field

[0001] This utility model relates to the field of wire harness connector protection, and in particular to a quick-release automotive wire harness connector protective shell. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals crimped to wires and cables, then covered with a molded insulator or an outer metal casing, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. During installation, protective housings are required to protect the wiring harness connectors.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In the existing technology, wire harness connector protective shells are usually fixed by bolt connection. This fixing method is inconvenient to disassemble and assemble. In addition, the existing technology usually only fixes the wire harness connector part. Under long-term use or pulling, the wire harness and connector contact point are prone to damage and breakage, affecting normal use.

[0005] Therefore, those skilled in the art have provided a quick-release automotive wiring harness connector protective housing to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a quick-release automotive wiring harness connector protective shell that can fix the wiring harness and facilitate quick disassembly and maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A quick-release automotive wiring harness connector protective shell includes an outer shell, a top plate movably disposed on the upper end face of the outer wall of the outer shell, five wire-fixing grooves opened at the center of the interior of the outer shell, sliding grooves opened on both sides of the interior of the outer shell, quick-release mechanisms are provided in two of the sliding grooves, each quick-release mechanism includes two sliding plates and a sliding rod, and telescopic rods are hinged to the upper center of the opposite side of two sliding plates located in the same sliding groove among the four sliding plates, a No. 1 spring is movably sleeved on the outer wall of each of the four telescopic rods, and an outer sleeve is slidably sleeved on the outer wall of each of the two sliding rods;

[0009] A connector fixing mechanism is provided at the upper end of both sides of the front end of the inner wall of the outer shell. The connector fixing mechanism includes a fixing plate and a clamping block. A threaded rod is rotatably provided at the center of both sides of the lower end face of the fixing plate. A wire harness fixing mechanism is provided at the rear end of the bottom end face of the inner wall of the outer shell. The wire harness fixing mechanism includes multiple clamping blocks and connecting rods. Five No. 2 springs are movably sleeved on the outer wall of the connecting rods.

[0010] Furthermore, the two threaded rods are threaded through the center of both sides of the upper end face of the card block and are respectively rotatably disposed on both sides of the front end of the bottom end face of the inner wall of the outer casing.

[0011] Furthermore, one end of each of the four telescopic rods is hinged to the lower ends of the front and rear ends of the outer walls of the two outer sleeves, and the upper ends of the two outer sleeves are fixedly connected to the lower end face of the top plate.

[0012] Furthermore, the lower end of the connecting rod is fixedly connected to the lower end of two clamping blocks located on opposite sides of the multiple clamping blocks and slides through the lower end of one side of the remaining multiple clamping blocks. The two ends of the five second springs are fixedly connected to two clamping blocks located at the rear end of the same wire groove of the multiple clamping blocks.

[0013] Furthermore, two of the four sliding plates located at the same end have handles fixedly installed at the lower end of the side away from the telescopic rod.

[0014] Furthermore, five grooves are provided at the center of the lower end face of the card block and the front end of the bottom end face of the inner wall of the outer shell.

[0015] Furthermore, the two ends of the four No. 1 springs are respectively fixedly connected to the two ends of the four telescopic rods.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a quick-release automotive wiring harness connector protective shell. Pulling the handles to both sides causes two sliding plates located at each end to move along two sliding grooves to one end away from each other, thereby pulling four telescopic rods to extend and causing four No. 1 springs to be in a stretched state. When the telescopic rods are stretched to their limit length, continuing to pull the handles causes the outer sleeve to push the top plate upward. After releasing the handles, the telescopic rods and No. 1 springs retract under the action of the four No. 1 springs, pulling two sliding plates inside the same sliding groove to move in opposite directions and close the top plate, thereby achieving the effect of facilitating quick disassembly and maintenance of the wiring harness.

[0018] 2. This utility model proposes a quick-release automotive wiring harness connector protective shell. The wiring harness connector is placed under the clamping block along the wire fixing groove. Then, the two threaded rods are rotated to move the clamping block downward and squeeze and fix the wiring harness connector. Then, the two clamping blocks located at the rear end of the same wire fixing groove are moved to both sides. Next, the wiring harness part is passed between the two clamping blocks and the clamping blocks are released. Under the action of the second spring, the two clamping blocks move in opposite directions to clamp and fix the wiring harness part, preventing damage or breakage at the connection between the wiring harness and the connector during long-term use or pulling, which would affect its use.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 4 One embodiment provided by this utility model:

[0027] A quick-release automotive wiring harness connector protective shell includes an outer shell 1. A top plate 3 is movably disposed on the upper end face of the outer wall of the outer shell 1. Five wire fixing grooves 6 are opened at the center of the interior of the outer shell 1. Sliding grooves 7 are opened on both sides of the interior of the outer shell 1. A quick-release mechanism 5 is provided inside each of the two sliding grooves 7. Each of the two quick-release mechanisms 5 includes two sliding plates 501 and a sliding rod 505. A telescopic rod 502 is hinged at the center of the upper end of the opposite side of the two sliding plates 501 located in the same sliding groove 7. A first spring 503 is movably sleeved on the outer wall of each of the four telescopic rods 502. An outer sleeve 504 is slidably sleeved on the outer wall of each of the two sliding rods 505.

[0028] A connector fixing mechanism 4 is provided on the upper part of both sides of the inner wall of the outer shell 1. The connector fixing mechanism 4 includes a fixing plate 401 and a clamping block 402. Threaded rods 403 are rotatably provided at the center of both sides of the lower end face of the fixing plate 401. A wire harness fixing mechanism 8 is provided at the rear end of the bottom end face of the inner wall of the outer shell 1. The wire harness fixing mechanism 8 includes multiple clamping blocks 801 and connecting rods 802. Five No. 2 springs 803 are movably sleeved on the outer wall of the connecting rods 802.

[0029] Specifically, the design of the wire fixing groove 6 can accommodate the wire harness and allow the wire harness connector to slide through the wire fixing groove 6 to the lower end of the clamping block 402 and be squeezed and fixed by the connector fixing mechanism 4. At the same time, the wire harness can be clamped and fixed by the wire harness fixing mechanism 8 located at the rear end, which can prevent the wire harness from breaking at the connection between the connector during long-term use or pulling. Furthermore, by pulling the two sliding plates 501 on the same side, the top plate 3 can be lifted by the quick release mechanism 5, which makes it easy to remove the wire harness and its connector from the inside of the outer shell 1 through the gap between the top plate 3 and the outer shell 1.

[0030] Reference Figure 1 , Figure 3 Two threaded rods 403 are threaded through the center of both sides of the upper end face of the locking block 402 and are respectively rotatably set on both sides of the front end of the bottom end of the inner wall of the outer casing 1.

[0031] Specifically, rotating the two threaded rods 403 simultaneously can drive the locking block 402 to move up and down, thereby achieving the effect of quick release and fixation of the wire harness connector.

[0032] Reference Figures 1 to 4 One end of each of the four telescopic rods 502 is hinged to the lower ends of the front and rear ends of the outer walls of the two outer sleeves 504, and the upper ends of the two outer sleeves 504 are fixedly connected to the lower end face of the top plate 3.

[0033] Specifically, when the telescopic rod 502 is at its maximum extension distance, continuing to pull the telescopic rod 502 can drive the outer sleeve 504 to move upward along the slide rod 505, thereby pushing the top plate 3 to move upward and separate from the upper surface of the outer shell 1.

[0034] Reference Figure 2 , Figure 3 , Figure 4 The lower end of the connecting rod 802 is fixedly connected to the lower end of the opposite side of two clamping blocks 801 located on both sides of the multiple clamping blocks 801, and slides through the lower end of one side of the remaining multiple clamping blocks 801. The two ends of the five No. 2 springs 803 are fixedly connected to the two clamping blocks 801 located at the rear end of the same wire groove 6 of the multiple clamping blocks 801.

[0035] Specifically, the elastic force of the second spring 803 can pull the two clamps 801 located at the rear end of the same wire fixing groove 6 closer together, thereby achieving the function of fixing the wire harness.

[0036] Reference Figures 1 to 4 Handles 2 are fixedly installed at the lower end of the side of the two sliding plates 501 located at the same end away from the telescopic rod 502.

[0037] Specifically, pulling handle 2 can cause two sliding plates 501 located at the same end to move simultaneously, thereby adjusting the extension length of telescopic rod 502 and spring 503.

[0038] Reference Figure 1 Five grooves are provided at the center of the lower end face of the card block 402 and the front end of the bottom wall of the outer shell 1.

[0039] Specifically, the grooves opened at the center of the lower end face of the locking block 402 and the front end of the bottom end of the inner wall of the outer shell 1 can achieve the effect of locking and fixing the wire harness connector.

[0040] Reference Figure 2 , Figure 3 , Figure 4 The two ends of the four No. 1 springs 503 are respectively fixedly connected to the two ends of the four telescopic rods 502.

[0041] Specifically, when the lower end of the outer sleeve 504 is located at the bottom surface of the sliding groove 7, the four No. 1 springs 503 and the four telescopic rods 502 are still in a stretched state, so as to provide a certain resistance to the movement when the top plate 3 is directly pulled upward, thereby achieving the locking effect of the top plate 3.

[0042] Working principle: Pulling the two handles 2 at the front and rear ends respectively causes the two sliding plates 501 at the same end and the two sliding plates 501 on the other side to slide in opposite directions, which in turn causes the first spring 503 and the telescopic rod 502 to extend. When the telescopic rod 502 extends to its maximum length, pulling the handle 2 will move it upward along the slide rod 505 through the telescopic rods 502 at both ends of the same outer sleeve 504. This causes the top plate 3 to move upward through the outer sleeve 504, creating a gap between the top plate 3 and the outer casing 1. Then, the two clamping blocks 801 located at the rear end of the same wire fixing groove 6 are moved to both sides, stretching the second spring 803 between them. Then, the wire harness connector slides through the wire fixing groove 6 into the groove at the lower end of the fixing plate 401. Finally, the two clamping blocks 801 are released, allowing it to... Under the action of spring 803, the wire harness moves in opposite directions to clamp and fix it. Then, the two threaded rods 403 are rotated to move the locking block 402 downward to squeeze and fix the wire harness connector. The two handles 2 are released so that the two springs 503 in the same sliding groove 7 can pull the two telescopic rods 502 to retract, thereby pulling the two sliding plates 501 in the same sliding groove 7 to move in opposite directions. Then, the outer sleeve 504 slides down along the sliding rod 505 and its lower end contacts the bottom surface of the sliding groove 7. At this time, the telescopic rod 502 and the spring 503 are still in a stretched state, so as to provide a certain resistance when directly pulling the top plate 3, thereby locking the top plate 3 and achieving the effect of quick disassembly and fixation of the wire harness and wire harness connector.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
