Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle parts technology, specifically to a motorcycle connector structure that prevents loosening. Background Technology
[0002] In the electrical system of a motorcycle, various sensors, lights, control units, and other components are often connected via connectors to transmit signals and electrical energy.
[0003] Because motorcycles operate under harsh conditions of high speed, bumpy roads, and continuous engine vibration, traditional plug-in structures rely solely on friction between the plug and socket for connection. Under prolonged vibration, these connections are prone to loosening or even detachment, leading to unstable circuit connections, signal interruptions, or power supply failures, which seriously affect driving safety and the reliability of the electrical system.
[0004] In addition, cables are often bent frequently by vehicle movement or pulled by external forces near the plug points, which can easily cause fatigue fracture of the cable core. This problem is even more prominent in high-frequency vibration environments.
[0005] Therefore, there is an urgent need for a plug-in structure that has reliable anti-loosening capabilities, is easy to operate, and can effectively disperse cable stress in order to adapt to the harsh operating environment of motorcycles. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle connector structure for preventing loosening, comprising a connector, the connector including a protective shell, with a plug and a cable respectively fixed at both ends of the protective shell.
[0007] The side of the connector is provided with a fastening assembly, which includes two sets of rotating mechanisms symmetrically arranged on the side of the protective shell. Two functional mechanisms are symmetrically arranged on the side of the rotating mechanism: a locking mechanism for connecting with the connector shell to prevent the connector from loosening or disengaging, and a swing arm mechanism for controlling the opening and closing movement of the locking mechanism.
[0008] One end of the swing arm mechanism is equipped with a fixing mechanism for securing the cable and preventing breakage at the connection point.
[0009] Preferably, both sets of rotating mechanisms include clamps fixed to the corresponding sides of the protective shell, and rotating cylinders are movably connected inside the clamps. Both ends of the rotating cylinders are provided with spring latches, which are rotatably connected to corresponding positions inside the clamps.
[0010] Preferably, torsion springs are installed between the two ends of the rotating cylinder and the opposite surfaces inside the clamping plate.
[0011] Preferably, the locking mechanism includes a support rod fixed to one side of the rotating cylinder, and a hook is fixed to the front end of the support rod.
[0012] Preferably, the swing arm mechanism includes two arms, namely a rear arm and a front arm, which are connected by an adjusting member, and one end of the rear arm is fixed to one side of the rotating cylinder.
[0013] Preferably, a rear connecting plate is fixed to one end of the rear support arm, and a front connecting plate is fixed to one end of the front support arm.
[0014] The adjusting component includes a threaded rod fixed to the front connecting plate and an adjusting ring rotatably connected to the rear connecting plate. The threaded rod passes through the rear connecting plate and is threaded into the adjusting ring.
[0015] Preferably, the fixing mechanism includes a limiting frame fixed to one end of the front support arm, and an opening is provided on the side of the limiting frame.
[0016] Preferably, one end of the limiting frame has a hollow groove, and an extension rod is movably sleeved in the hollow groove, with one end of the extension rod passing through the opening.
[0017] Preferably, a limiting groove penetrating the inner wall of the limiting frame is provided on one side of the hollow groove, and a slider is provided on the side of the extension rod, which is slidably connected in the limiting groove.
[0018] Preferably, the limiting groove has multiple positioning recesses distributed in it, and the side of the slider has positioning beads that are engaged in the corresponding positioning recesses.
[0019] Compared with the prior art, this utility model provides a motorcycle connector structure that prevents loosening, which has the following advantages:
[0020] 1. This anti-loosening motorcycle plug-in structure, through a symmetrically arranged rotating mechanism and torsion spring reset mechanism, automatically hooks the end of the socket housing after plugging in, forming a mechanical interlock. This completely prevents the plug from coming loose due to vehicle vibration, greatly improving connection stability and safety. Furthermore, by pressing outward or moving the swing arm mechanism on both sides, the locking mechanism can be opened or retracted, achieving synchronous locking during plugging in and quick unlocking before unplugging.
[0021] 2. This anti-loosening motorcycle connector structure mechanically locks the connector to the external socket through a locking mechanism. At the same time, it uses a lever principle to make the limiting frame at the tail end of the swing arm mechanism abut against the side of the cable, effectively preventing the connector from breaking at the cable connection. Meanwhile, the adjustable extension rod and the limiting frame structure with positioning beads can accommodate cables of different diameters and firmly clamp them at the tail end of the connector, preventing the cable from bending or shaking during vibration, significantly reducing the risk of core wire breakage and extending service life.
[0022] 3. This anti-loosening motorcycle connector structure allows for quick disengagement or installation into the clamp by pressing the spring latches at both ends of the rotating cylinder. After disengagement, the connector can be used independently, further improving the flexibility of the connector structure. Attached Figure Description

Detailed Implementation
[0030] 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.
[0031] Example 1
[0032] Please see Figure 1 - Figure 4 As shown, the anti-loosening motorcycle connector structure proposed in this embodiment includes a connector 1 and a fastening assembly 2.
[0033] The connector 1 includes a protective shell 11 with a square or rectangular cross-section. The shell is made of engineering plastic and has a certain rigidity and weather resistance. A plug 12 (male or female) is fixed to the front end of the protective shell 11, while the tail end is crimped or potted to fix it to the cable 13 for transmitting electrical signals or electrical energy.
[0034] The fastening assembly 2 is located on the side of the protective shell 11. It includes two sets of symmetrically arranged rotating mechanisms 21. Each set of rotating mechanisms includes a U-shaped clamping plate 211 fixed to the side of the protective shell 11 by screws. The opening of the clamping plate 211 faces outward horizontally, and round holes are provided at the top and bottom. A rotating cylinder 212 is movably connected inside the clamping plate 211. The rotating cylinder 212 is engaged in the round holes provided at both ends by spring latches 2121, so that the rotating cylinder 212 can rotate inside the clamping plate 211 with the spring latches 2121 as the axis, while preventing the rotating cylinder 212 from falling off the clamping plate 211.
[0035] It should be further explained that by simultaneously pressing the spring latches 2121 at both ends of the rotating cylinder 212, the rotating cylinder 212 can be quickly detached from the connector 1.
[0036] Meanwhile, torsion springs 213 are installed between the two ends of the rotating cylinder 212 and the inner opposite surfaces of the clamping plate 211, so that when the external force on the rotating cylinder 212 is released, it tends to return to the initial position.
[0037] A locking mechanism 22 is fixed on one side of the rotating cylinder 212. The mechanism includes a support rod 221 fixed to the rotating cylinder 212. A hook 222 perpendicular to the support rod 221 is fixed at the front end of the support rod 221. When the plug 1 is plugged into the external connector, the torque of the torsion spring 213 on the rotating cylinder 212 causes the hook 222 to engage with the outer wall of the tail end of the external connector housing, thereby preventing the plug 1 from loosening due to vibration.
[0038] On the other side of the rotating cylinder 212, and symmetrically positioned with the locking mechanism 22, a swing arm mechanism 23 is provided. This mechanism includes a rear support arm 231 and a front support arm 232, which are connected by an adjusting member 233. At the same time, one end of the rear support arm 231 is fixed to the side wall of the rotating cylinder 212 by welding.
[0039] More specifically, a rear connecting plate 2311 is vertically fixed to the end of the rear control arm 231, and a front connecting plate 2321 is vertically fixed to the end of the front control arm 232.
[0040] The adjusting member 233 includes a threaded rod 2331 fixed on the front connecting plate 2321 and an adjusting ring 2332 rotatably connected to the rear connecting plate 2311 via a bearing. The threaded rod 2331 passes through the front connecting plate 2321 and is screwed into the adjusting ring 2332. By rotating the adjusting ring 2332, the extension length of the front support arm 232 relative to the rear support arm 231 can be changed, thereby fixing the end-mounted mechanism (hereinafter referred to as the fixing mechanism) at the appropriate position of the cable.
[0041] A fixing mechanism 24 is installed at the end of the front support arm 232 away from the rotating cylinder 212. This mechanism is used to clamp and fix the cable 13 led out from the connector to prevent the core wire from breaking due to bending or shaking near the connection point. The mechanism includes a limiting frame 241 fixed to the end of the front support arm 232. The limiting frame 241 is generally rectangular or an inverted O-shape, and has an opening 2411 at the top for inserting the cable.
[0042] Inside one end of the limiting frame 241, there is an arc-shaped hollow groove 242 along its path. An arc-shaped extension rod 243 with a diameter matching the inner diameter of the groove is movably sleeved inside the hollow groove 242. One end of the extension rod 243 can pass through the opening 2411 and extend into the inner cavity of the limiting frame 241 to press the cable 13 placed therein.
[0043] In addition, a limiting slide groove 244 is provided on one side of the hollow groove 242, which penetrates the side wall of the limiting frame 241. At the same time, a slider 245 is fixed on the side of the tail end of the extension rod 243. The slider 245 is nested in the limiting slide groove 244 and can slide along it to control the length of the extension rod 243 extending outward.
[0044] The groove wall of the limiting slide 244 has a plurality of spaced positioning recesses 246. The side of the slider 245 is equipped with a spring-loaded positioning bead 247. When the sliding extension rod 243 is moved to the appropriate position, the positioning bead 247 is engaged in the corresponding positioning recess 246 under the action of the spring, thereby positioning the extension rod 243 and thus adapting to the fixing of cables of different diameters.
[0045] The working principle of the anti-loosening motorcycle plug structure proposed in this embodiment is as follows: When in use, first insert the plug 12 into the corresponding socket. At the same time, pinch the front support arm 232 of the two swing arm mechanisms 23 with your fingers and press it inward. The pressing action causes the rotating cylinder 212 to rotate against the torque of the torsion spring 213. The rotation of the rotating cylinder 212 will synchronously drive the locking mechanism 22 fixed to it to open outward until the plug 12 is fully inserted into the corresponding socket. Then release the swing arm mechanism 23. At this time, the torque of the torsion spring 213 is released, and the rotating cylinder 212 rotates in the opposite direction to the initial position, causing the hook 222 at the front end of the support rod 221 to swing inward and hook onto the wall at the rear end of the socket housing to complete the mechanical locking and prevent it from disengaging. At this time, the swing arm mechanism 23 itself is in a retracted state and does not occupy too much space.
[0046] Next, the cable 13 is inserted into the U-shaped cavity of the limiting frame 241 through the opening 2411. The extension rod 243 is slid according to the cable diameter so that the end of the extension rod 243 presses against the cable. The position is fixed by the cooperation of the positioning bead 247 and the positioning recess 246, thereby clamping and fixing the cable and eliminating the stress at the connection.
[0047] When you need to unplug the plug, first slide the extension rod 243 to loosen the cable, then move the front support arm 232 of the two swing arm mechanisms 23 outward. The swing arm mechanism 23 drives the rotating cylinder 212 to rotate in the opposite direction, so that the hook 222 is disengaged from the socket housing and the lock is released. At this time, you can unplug the plug smoothly.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
