Description

Technical Field

[0001] This utility model relates to the field of circuit connection protection technology, specifically to a protective component for automotive headlight circuit connections. Background Technology

[0002] Automotive headlight wiring connection protection components are a series of parts used to protect the connection points of headlight wiring and ensure their safe and stable operation. The wiring harness sealing sleeve is a key protective component, usually made of thermoplastic materials or rubber compounds. Its main function is to allow the wires to pass through the outside of the headlight housing and into the inside, while forming a reliable sealing barrier. Depending on the material and structure, wire harness sealing sleeves can be divided into rigid sealing sleeves and flexible sealing sleeves. The former is generally made of thermoplastic material through injection molding and is suitable for vehicle lamp interfaces that need to maintain sealing performance for a long time. The latter is mostly made of rubber compounds and can adapt to irregular wire hole shapes. It is often used in dynamic parts where vehicle lamps are connected to the vehicle body. Automotive headlight wiring harnesses typically use lip-sealed sleeves to form multiple seals around the wiring holes. Once the sleeve has wrapped the wiring harness, if a short circuit or open circuit occurs inside, the sleeve must be removed before the wiring can be inspected due to its protective properties. During repairs, not only must the operator be careful to avoid damaging the wiring harness and surrounding components, but more time and effort must also be spent separating the different layers of the sleeve, which greatly extends the repair time and increases the difficulty and cost of the repair work. Therefore, a protective component for automotive headlight wiring connections is proposed to address the above-mentioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a protective component for automotive headlight wiring connections, in order to solve the problem that due to the protective characteristics of the sealing sleeve, maintenance personnel must first remove the sealing sleeve before they can carry out wiring inspection. During maintenance, not only must they operate carefully to avoid damaging the wiring harness and surrounding components, but they also need to spend more time and effort to separate the various layers of the sealing sleeve, which increases the difficulty and cost of maintenance work.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A protective assembly for automotive headlight wiring connections includes a connecting end, a protective tube, and arc-shaped slots. One end of the connecting end is fixedly connected to the protective tube. Two symmetrically arranged arc-shaped slots are formed on the outer side of the protective tube. A limit block is fixedly connected to the inner side of one end of the connecting end. A wire insertion end is installed on one end of the connecting end. A self-locking mechanism is slidably connected to the outer side of the wire insertion end, and an unlocking device is slidably connected to the inner side of the self-locking mechanism. The self-locking mechanism includes a main body with two annular grooves on its inner side. Three elastic rings are slidably connected to the outer side of the annular grooves. Fixed rings are fixedly connected to the outer sides of both ends of the annular grooves. Triangular blocks are fixedly connected to the outer sides of the elastic rings. A second spring is fixedly connected to the outer side of the elastic rings. A sliding groove is formed at one-third of the outer side of the main body of the self-locking mechanism, and an unlocking device is slidably connected inside the sliding groove.

[0005] As a further optimization of this utility model, the unlocking device includes a sliding button, a friction post fixedly connected to the upper end of the sliding button, a connector fixedly connected to the lower end of the sliding button, a limit ring fixedly connected to one end of the connector, and a first spring fixedly connected to one side of the limit ring.

[0006] As a further optimization of this utility model, the self-locking mechanism body is sleeve-shaped, and two annular grooves are provided on the inner side of the self-locking mechanism body at intervals along the axial direction of the self-locking mechanism body. The center of the annular grooves coincides with the center of the self-locking mechanism body, the cross-section of the annular grooves is rectangular, and the two annular grooves have the same size.

[0007] As a further optimization of this utility model, the fixing ring and the annular groove are coaxially arranged, the inner side of the elastic ring contacts the outer side wall of the insertion end, the elastic ring is sleeved in the annular groove, and the outer side of the elastic ring is tightly fitted with the inner side wall of the annular groove.

[0008] As a further optimization of this utility model, the triangular block is a triangular prism structure, and two triangular blocks are fixedly connected to the outside of each elastic ring. The two triangular blocks are symmetrically distributed with the center of the elastic ring as the center. One side of the triangular block is fixed to the outer wall of the elastic ring, and the other two sides of the triangular block are inclined surfaces.

[0009] As a further optimization of this utility model, the second spring is a cylindrical helical spring, and the other end of the second spring is fixedly connected to the inner wall of the annular groove. Two second springs are connected to the outer side of each elastic ring, and the two second springs are distributed in a one-to-one correspondence with the two triangular blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the self-locking mechanism, through the cooperation of an elastic ring, a triangular block, and a second spring, compresses and contracts the elastic ring during insertion. Once in place, the spring drives the triangular block to engage with the arc-shaped groove, locking evenly from the circumference, resisting vibration and pulling, preventing wire loosening, and ensuring stable circuit connection. The long sliding button of the unlocking device is easy to operate with the hand, and the first spring accurately resets, ensuring automatic return to its original position after unlocking. This greatly simplifies the maintenance process and improves repair efficiency. The elastic ring tightly fits the arc-shaped groove and the annular groove, forming a protective barrier to prevent moisture and dust from entering. Attached Figure Description

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A protective component for automotive headlight wiring connections includes a connecting end 1, a protective tube 2, and an arc-shaped groove 3. The protective tube 2 is fixedly connected to one end of the connecting end 1. Two symmetrically arranged arc-shaped grooves 3 are formed on the outer side of the protective tube 2. A limit block 4 is fixedly connected to the inner side of one end of the connecting end 1. A wire insertion end 5 is installed on one end of the connecting end 1. A self-locking mechanism 6 is slidably connected to the outer side of the wire insertion end 5. An unlocking device 7 is slidably connected to the inner side of the self-locking mechanism 6. The self-locking mechanism 6 includes a self-locking mechanism body 61. Two annular grooves 62 are formed on the inner side of the self-locking mechanism body 61. Three elastic rings 64 are slidably connected to the outer side of the annular grooves 62. Fixed rings 63 are fixedly connected to the outer sides of both ends of the annular grooves 62. Triangular blocks 65 are fixedly connected to the outer sides of the elastic rings 64. A second spring 66 is fixedly connected to the outer side of the elastic rings 64. A sliding groove 67 is formed at one-third of the outer side of the self-locking mechanism body 61. An unlocking device 7 is slidably connected inside the sliding groove 67.

[0017] As a further implementation of the above technical solution: the fixed ring 63 and the annular groove 62 are coaxially arranged, the inner side of the elastic ring 64 contacts the outer side wall of the plug end 5, the elastic ring 64 is sleeved in the annular groove 62, and the outer side of the elastic ring 64 is tightly fitted with the inner side wall of the annular groove 62, providing a clear axial limit boundary for the elastic ring 64, preventing the elastic ring 64 from moving axially under conditions such as plugging and vibration, ensuring that the triangular block 65 and the arc-shaped slot 3 are stably engaged during self-locking, and the locking reliability is higher. It can prevent moisture and dust from entering from the gap between the arc-shaped slot 3 and the self-locking mechanism 6, protect the internal circuit connection points, and improve the durability of the vehicle lamp in humid and dusty environments. As a further implementation of the above technical solution: the second spring 66 is a cylindrical helical spring, and the other end of the second spring 66 is fixedly connected to the inner wall of the annular groove 62. Two second springs 66 are connected to the outside of each elastic ring 64. The two second springs 66 are distributed one-to-one with the two triangular blocks 65. The reset force can be accurately provided according to the deformation of the elastic ring 64, to compensate for the displacement of the elastic ring 64 under different insertion depths and vibration conditions, and to always maintain the effective engagement of the triangular block 65 with the arc-shaped groove 3, thereby enhancing the adaptability of the self-locking mechanism 6. As a further implementation of the above technical solution: the sliding button 71 is a long strip structure, the outer side of the sliding button 71 is slidably connected to the outer side of the slide groove 67, the limiting ring 74 is sleeved on the inner side of the self-locking mechanism body 61, the first spring 75 is sleeved on the outer side of the connector 73, and the other end of the first spring 75 is fixed to the inner side of the self-locking mechanism body 61. The first spring 75 provides a stable restoring force. After unlocking, the sliding button 71 and the limiting ring 74 are automatically returned to their positions without manual adjustment, ensuring that the initial state of the next self-locking and unlocking cycle is consistent and improving the stability of the component for repeated use. As a further implementation of the above technical solution: the triangular blocks 65 are triangular prisms, and two triangular blocks 65 are fixedly connected to the outside of each elastic ring 64. The two triangular blocks 65 are symmetrically distributed with the center of the elastic ring 64 as the center. One side of the triangular block 65 is fixed to the outer wall of the elastic ring 64, and the other two sides of the triangular block 65 are inclined surfaces. When the connecting end 1 is inserted, the inclined surfaces can guide the elastic ring 64 to contract smoothly, reduce the insertion resistance, and facilitate quick assembly. After insertion, the inclined surfaces and the arc-shaped groove 3 of the connecting end 1 provide reverse support, which can effectively resist vibration and tension and prevent the plug end 5 from loosening. As a further implementation of the above technical solution: the unlocking device 7 includes a sliding button 71, a friction post 72 is fixedly connected to the upper end of the sliding button 71, a connector 73 is fixedly connected to the lower end of the sliding button 71, a limit ring 74 is fixedly connected to one end of the connector 73, and a first spring 75 is fixedly connected to one side of the limit ring 74. The friction post 72 increases the friction of the sliding button 71, making it less likely for maintenance personnel to slip during operation and enabling precise control of the unlocking force and stroke. As a further implementation of the above technical solution: the self-locking mechanism body 61 is sleeve-shaped, and two annular grooves 62 are distributed axially along the inner side of the self-locking mechanism body 61. The center of the annular grooves 62 coincides with the center of the self-locking mechanism body 61. The cross-section of the annular grooves 62 is rectangular, and the two annular grooves 62 are the same size. This makes the locking force on the plug end 5 more balanced, avoids deformation and poor contact of the plug end 5 due to uneven force, improves the stability of the circuit connection, and the symmetrical axial spacing distribution can adapt to the locking requirements of different lengths of the connection end 1, enhance the versatility of the components, and reduce the vehicle model adaptation development cycle.

[0018] Workflow: First, connect the connector 1 to the fixed wiring terminal inside the headlight. The protective tube 2 provides physical protection for the wiring harness. The connector 1 is pre-positioned at the opening of the connector 1, ready to be inserted into the plug terminal 5 to achieve circuit connection. At this time, the self-locking mechanism 6 is sleeved on the outside of the plug terminal 5, and the unlocking device 7 is pre-installed in the slide groove 67 of the self-locking mechanism 6. Push the connector 1 into the plug terminal 5. When the inner side of the plug terminal 5 contacts the limiting block 4 on the inner side of the connector 1, it reaches the preset insertion depth to ensure stable circuit connection. At the same time, the plug terminal 5 squeezes the elastic ring 64 inside the self-locking mechanism 6 to prepare for self-locking. During the insertion of the plug end 5, its outer wall compresses the elastic ring 64. After being compressed, the elastic ring 64 contracts inward toward the annular groove 62, causing the outer triangular block 65 to move synchronously. The second spring 66 is stretched and stores energy. When the plug end 5 is fully inserted and the elastic ring 64 passes the preset groove on the outside of the connecting end 1, the second spring 66 returns to its original position, pulling the elastic ring 64 to rebound and expand. The triangular block 65 is then engaged in the arc-shaped groove 3 of the connecting end 1. The three elastic rings 64 are evenly distributed along the annular groove 62 and engage synchronously, locking the relative position of the plug end 5 and the connecting end 1 circumferentially, achieving self-locking and preventing the plug end 5 from falling off due to vibration or external pulling. When the wire end 5 is connected to the connecting end 1, operate the sliding button 71. Press the friction post 72 at the upper end of the sliding button 71 with your finger to push the sliding button 71 to slide along the slide groove 67, which drives the connecting piece 73 at the lower end to move synchronously. The limiting ring 74 moves with the connecting piece 73, compressing the first spring 75 to store energy. When the connecting piece 73 moves, it drives the limiting ring 74 to squeeze the elastic ring 64. The limiting ring 74 is a ring structure and is fitted inside the self-locking mechanism body 61. During its movement, it squeezes the elastic ring 64 from the inside towards the annular groove 62, forcing the elastic ring 64 to contract towards the inside of the annular groove 62. The triangular block 65 then disengages from the arc-shaped slot 3 of the connecting end 1, releasing the circumferential lock.
