Description

Technical Field

[0001] This utility model belongs to the field of engine wiring harness connector technology, specifically a hinged variable angle wiring harness connector. Background Technology

[0002] As a key component in the engine electrical system for realizing the electrical connection between the wiring harness and electrical components, the wiring harness connector has a significant impact on the rationality of the engine wiring harness layout.

[0003] Currently, the standard practice in the industry for assembling wiring harnesses and connectors is that after the wiring harness is connected, it is usually arranged coaxially with the connector, meaning the wiring harness runs in the same direction as the connector. However, the internal space of an engine is complex and confined. To accommodate the installation positions of different electrical components and avoid other mechanical structures such as the engine block and pipelines, the wiring harness routing often needs to be adjusted to change its axial angle with the connector in actual installation.

[0004] Existing adjustment methods mostly rely on cable ties for binding and fixing. This method not only fails to accurately control the direction of the wiring harness, but also adds extra steps to the operation, causing significant inconvenience to the overall layout of the engine wiring harness and making it difficult to meet the requirements for precision and convenience in engine wiring harness layout. Summary of the Invention

[0005] To address the problems existing in the background technology, this utility model provides a hinged variable angle wire harness connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hinged variable angle wire harness connector, comprising a sub-end fixed sub-assembly, a sub-end turntable sub-assembly, a central shaft conductive copper disk, a central shaft conductive copper sleeve, a rotating conductive copper disk, a rotating disk terminal block, a central disk terminal block, a steering locking wheel outer ring, a steering locking wheel inner ring, two sub-end and female end connection holes, two sub-end current output terminals, multiple rotating contact springs, and multiple pressure plate contact springs; The sub-end fixing sub-assembly has an annular groove and a central groove at one end, with the central groove located within the annular groove. The other end of the sub-end fixing sub-assembly has two sub-end and female connection holes, which communicate with the corresponding annular groove or central groove, respectively. The central shaft conductive copper disk is installed in the central groove, and a central disk terminal is fixed to one end face of the central shaft conductive copper disk. The central disk terminal is connected to the corresponding sub-end and female connection hole via a wire. The central shaft conductive copper sleeve is pressed into the inner wall of the central groove and pressed tightly against the other end face of the central shaft conductive copper disk. The rotating conductive copper disk is installed in the annular groove, and a rotating disk terminal is provided on the rotating conductive copper disk. The rotating disk terminal is connected to the corresponding sub-end and female connection hole via a wire. The outer wall of the sub-end fixing sub-assembly has... The inner ring of the steering locking wheel and the outer ring of the steering locking wheel are provided on the inner wall of the sub-end turntable sub-assembly. The outer ring of the steering locking wheel and the inner ring of the steering locking wheel are configured to be interference-fitted. The bottom surface of the sub-end turntable sub-assembly is provided with a protruding shaft, which is inserted into the central groove of the sub-end fixing sub-assembly. Multiple pressure plate contact springs are evenly distributed circumferentially on the outer wall of the protruding shaft. The multiple pressure plate contact springs are all in contact with the inner wall of the central shaft conductive copper sleeve. The sub-end turntable sub-assembly is provided with two sub-end current output terminals. The multiple pressure plate contact springs are all connected to the corresponding sub-end current output terminals. The bottom surface of the sub-end turntable sub-assembly is evenly distributed with multiple rotating contact springs. The multiple rotating contact springs are all in contact with one end face of the rotating conductive copper disk and are connected to the corresponding sub-end current output terminals.

[0007] The outer ring of the steering locking wheel is an annular base structure. The inner wall of the annular base is evenly distributed with several prisms along the circumference. The annular base of the steering locking wheel outer ring is fixed to the inner wall of the sub-end turntable sub-assembly. The inner ring of the steering locking wheel is an annular base structure adapted to the outer ring of the steering locking wheel. The outer wall of the annular base is evenly distributed with several prisms or grooves that are adapted to the prisms of the inner wall of the steering locking wheel outer ring along the circumference. The annular base of the steering locking wheel inner ring is fixed to the outer wall of the sub-end fixing sub-assembly. The prisms of the inner wall of the steering locking wheel outer ring and the prisms or grooves of the outer wall of the steering locking wheel inner ring are inserted and engaged. The steering locking wheel outer ring and the steering locking wheel inner ring are interference fit.

[0008] Of the two female and male connector holes, one is connected to the central slot and connected to the central disk terminal via a wire, and the other is connected to the annular slot and connected to the rotating disk terminal via a wire.

[0009] As the sub-end turntable assembly rotates, the multiple pressure plate contact springs are always in contact with the inner wall of the central shaft conductive copper sleeve, and the multiple rotating contact springs are always in contact with one end face of the rotating conductive copper disk as the sub-end turntable assembly rotates.

[0010] The output direction of the sub-terminal current output terminal forms a 90-degree angle with the axis of the sub-terminal fixed sub-assembly, and the sub-terminal current output terminal rotates with the sub-terminal turntable sub-assembly around the axis of the sub-terminal fixed sub-assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Precise adjustment of wiring harness routing to adapt to complex engine layout requirements: This connector features a 90-degree angle between the current output terminal and the fixed sub-assembly, combined with the 360-degree rotation function of the sub-end turntable sub-assembly around the fixed sub-assembly. This allows the wiring harness, which was originally arranged along the connector's axis, to be precisely turned 90 degrees and then rotated around the axis to any target direction without relying on cable ties or other auxiliary parts for fixation. This completely solves the problem of inaccurate control of the routing of traditional wiring harnesses after connection, which causes inconvenience for engine wiring harness layout. It can flexibly adapt to complex wiring harness layout scenarios in the confined space inside the engine.

[0012] 2. Ensure stable transmission of two current paths and avoid the risk of operational interruption: This connector achieves continuous and stable transmission of two current paths from the male and female terminals to the male current output terminal through the tight fit of the central shaft conductive copper disk, the central shaft conductive copper sleeve and the pressure plate contact spring, as well as the tight fit of the rotating conductive copper disk and the rotating contact spring. Both types of springs remain in contact as the male terminal turntable sub-assembly rotates, ensuring that the current transmission is not interrupted by the rotation of the male terminal turntable sub-assembly or slight vibrations during engine operation, thus ensuring the stable operation of the engine's related electrical systems.

[0013] 3. Achieve self-locking at any angle, avoiding harness wear and angle deviation: This connector uses an interference fit design between the outer and inner rings of the steering lock wheel. After manually rotating the sub-end turntable assembly to the target angle, the prisms of the inner and outer rings of the lock wheel can achieve a tight fit through elastic recovery. The friction generated by the fit can effectively prevent relative rotation between the two, keeping the current output terminal of the sub-end stable at the target angle. This minimizes the risk of harness friction with surrounding components or connector angle deviation caused by vibration during engine operation, thus extending the service life of the harness.

[0014] 4. Compact and reasonable structure, contributing to the compact design of the entire engine: This connector integrates the central shaft conductive copper disk and the rotating conductive copper disk into the central groove and annular groove of the sub-end fixed sub-assembly, respectively. The sub-end turntable sub-assembly is adapted and assembled with the sub-end fixed sub-assembly through a protruding shaft. The overall structure is highly integrated, without occupying too much internal engine space. At the same time, its design that eliminates the need for cable ties to fix the wiring harness further reduces space waste, meeting the engine's requirement for "improved compact design" and helping the engine achieve the goal of miniaturization and compact design.

[0015] 5. Convenient and efficient operation, reducing installation and maintenance costs: The angle adjustment of this connector can be achieved simply by manually applying rotational force to the sub-end turntable sub-assembly, without the need for professional tools, making operation simple and convenient; during engine maintenance, the wiring harness routing can be flexibly adjusted according to maintenance needs, avoiding time-consuming disassembly and installation problems caused by complex wiring harness fixing methods, reducing the difficulty and time cost of maintenance operations, and reducing the risk of accidentally damaging the wiring harness or connector during maintenance.

[0016] In summary, this utility model, through precise structural design, solves the problems of difficult routing control, insufficient current transmission stability, and large space occupation of traditional wiring harness connectors. It further achieves convenient operation and reliable operation, which can not only meet the functional requirements of engine wiring harness layout, but also help to improve the compact design and maintenance efficiency of the engine, and has significant practical value and application advantages.

The inner wall of the sub-end turntable sub-assembly 2 is provided with a steering locking wheel outer ring 11. The steering locking wheel outer ring 11 and the steering locking wheel inner ring 12 are configured to mesh with an interference fit. The bottom surface of the sub-end turntable sub-assembly 2 is provided with a protruding shaft. The protruding shaft is inserted into the central groove of the sub-end fixing sub-assembly 1. Multiple pressure plate contact springs 7 are evenly distributed circumferentially on the outer wall of the protruding shaft. The multiple pressure plate contact springs 7 are all in contact with the inner wall of the central shaft conductive copper sleeve 4. The sub-end turntable sub-assembly 2 is provided with two sub-end current output terminals 13.

The multiple rotating contact springs 6 are all in contact with one end face of the rotating conductive copper disk 5. The multiple rotating contact springs 6 are all connected to the corresponding sub-end current output terminals 13.

[0020] The outer ring 11 of the steering locking wheel is an annular base structure. The inner wall of the annular base is evenly distributed with several prisms along the circumference. The annular base of the outer ring 11 of the steering locking wheel is fixed to the inner wall of the sub-end turntable sub-assembly 2. The inner ring 12 of the steering locking wheel is an annular base structure adapted to the outer ring 11 of the steering locking wheel. The outer wall of the annular base is evenly distributed with several prisms or grooves that are adapted to the prisms of the inner wall of the outer ring 11 of the steering locking wheel. The annular base of the inner ring 12 of the steering locking wheel is fixed to the outer wall of the sub-end fixing sub-assembly 1. The prisms of the inner wall of the outer ring 11 of the steering locking wheel and the prisms or grooves of the outer wall of the inner ring 12 of the steering locking wheel are inserted and engaged. The outer ring 11 of the steering locking wheel and the inner ring 12 of the steering locking wheel are interference fit.

[0021] Of the two female and male connector holes 10, one is connected to the central groove and connected to the central disk terminal 9 via a wire, and the other is connected to the annular groove and connected to the rotating disk terminal 8 via a wire.

[0022] When the plurality of pressure plate contact springs 7 rotate with the sub-end turntable sub-assembly 2, they are always in contact with the inner wall of the central shaft conductive copper sleeve 4, and when the plurality of rotating contact springs 6 rotate with the sub-end turntable sub-assembly 2, they are always in contact with one end face of the rotating conductive copper disk 5.

[0023] The output direction of the sub-terminal current output terminal 13 is at a 90-degree angle to the axis of the sub-terminal fixed sub-assembly 1, and the sub-terminal current output terminal 13 rotates with the sub-terminal turntable sub-assembly 2 around the axis of the sub-terminal fixed sub-assembly 1.

[0024] The working principle of this hinged variable angle wire harness connector revolves around the stable transmission of two currents and the adjustable angle with a self-locking function. The specific process is as follows: When the two sub-ends and the female end of the fixed sub-assembly 1 are connected to the female end, one of the currents is input from one end of the connector 10, transmitted through the wire to the central plate terminal 9 fixed on the central shaft conductive copper plate 3, and then transmitted through the central shaft conductive copper plate 3 to its other end face. Since the central shaft conductive copper sleeve 4 has been pressed into the inner wall of the central groove of the sub-end fixed sub-assembly 1 and is pressed tightly against the central shaft conductive copper plate 3, the current is further transmitted to the central shaft conductive copper sleeve 4. Also, the multiple pressure plate contact springs 7 on the inner bottom surface of the sub-end turntable sub-assembly 2 protruding from the outer wall of the shaft are always in contact with the inner wall of the central shaft conductive copper sleeve 4, and the current is transmitted through the pressure plate contact springs 7 to the corresponding sub-end current output terminal 13 on the sub-end turntable sub-assembly 2. Another current is input from the other end of the connector 10, transmitted through the wire to the rotating disk terminal 8 fixed on the rotating conductive copper disk 5, and then conducted through the rotating conductive copper disk 5 to its end face. Multiple rotating contact springs 6 on the bottom surface of the sub-end turntable sub-assembly 2 are always in contact with the end face of the rotating conductive copper disk 5. The current is transmitted through the rotating contact springs 6 to the corresponding other sub-end current output terminal 13 on the sub-end turntable sub-assembly 2. Regardless of whether the sub-end turntable sub-assembly 2 rotates, the two types of springs remain in contact to ensure continuous current transmission. During angle adjustment and self-locking, the output direction of the current output terminal 13 of the sub-end is at a 90-degree angle to the axis of the sub-end fixed sub-assembly 1. The outer ring 11 of the steering locking wheel is a ring structure with prisms evenly distributed circumferentially on its inner wall, and the inner ring 12 of the steering locking wheel is a matching ring structure with prisms evenly distributed circumferentially on its outer wall. When a rotational force is manually applied to the sub-end turntable sub-assembly 2, the outer ring 11 of the steering locking wheel, fixed to its inner wall, rotates synchronously with the sub-end turntable sub-assembly 2 around the axis of the sub-end fixed sub-assembly 1. At this time, the prisms on the inner wall of the outer ring 11 of the steering locking wheel are aligned with the axis of the sub-end fixed sub-assembly 1. The prism on the outer wall of the inner ring 12 of the steering locking wheel, which is fixed to the outer wall of assembly 1, is elastic and can deform slightly to overcome the frictional force generated by the interference fit and maintain the plug-in engagement state. After rotating to the target angle, the applied rotational force is stopped, the prism elastically recovers, and the prism of the outer ring 11 of the steering locking wheel and the inner ring 12 of the steering locking wheel fit tightly together through the interference fit. The frictional force generated by the fit prevents the two from rotating relative to each other, so that the sub-end turntable sub-assembly 2 and the sub-end current output terminal 13 are stably maintained at the target angle, realizing self-locking to avoid engine vibration causing angle deviation.
