Description

Technical Field

[0001] This utility model relates to the field of ignition coil technology, and more specifically, to a quick connector device for automotive ignition coils. Background Technology

[0002] As the global automotive industry rapidly advances towards intelligence, electrification, and connectivity, the integration and complexity of automotive electronic systems are constantly increasing. As a core component of the engine, the ignition system faces higher demands for ignition accuracy, response speed, and stability. Traditional ignition coil connector connection methods and structural designs are no longer sufficient to meet the high-speed, precise signal transmission requirements of modern automotive electronic systems. Furthermore, the increasing scale and automation of automobile production present new challenges to the ease of component installation and production efficiency. The development of quick-connect coupling equipment helps meet the assembly needs of large-scale automobile production.

[0003] There are many existing technologies for ignition coil connectors, such as:

[0004] According to Chinese patent application number CN202022875517.9, specifically an automotive ignition coil connector, relating to the field of ignition coil technology, this automotive ignition coil connector includes an ignition coil body. A power connector is provided at the head of the ignition coil body. The power connector includes a socket and a metal core disposed within the socket. A guide strip is provided within the socket, located in the middle of the metal core. An extension plate is provided on the outer side of the socket. The socket is mounted to the central axis of a limiting wheel via the extension plate. The limiting wheel is horizontally positioned, with its side near the socket penetrating the side panel of the socket and extending into the socket, and located outside the metal core. The rotation of the limiting wheel is locked by a locking component. This utility model, by setting the guide strip, limiting wheel, and locking component, achieves a tight connection and easy removal, solving the problem that it is difficult to remove the automotive ignition coil head after connecting to the automotive power connector, and that the wire is easily broken or damaged.

[0005] Traditional automotive ignition coil connectors often use threaded or snap-fit ​​connections, which have many drawbacks. In terms of connection efficiency, threaded connections require manual tightening one turn at a time, which is time-consuming and prone to being too tight or too loose. While snap-fit ​​connections are relatively simple to operate, they are prone to fatigue damage due to vibration and other factors during long-term use, leading to loosening of the connection. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a quick connector device for automotive ignition coils. It solves the problems of low connection efficiency of ignition coil connectors in traditional technology and the easy fatigue damage of the clips due to vibration and other factors during long-term use, which leads to loose connections.

[0007] To achieve the above objectives, this utility model provides a quick connector device for automotive ignition coils, including a mounting base. A connector is fixedly connected to one end of the top of the mounting base. A connecting seat is provided on the top of the connector. A locking component is provided inside the connector. The locking component includes a sliding block. A sliding groove is symmetrically arranged inside the connector. The connecting seat is slidably connected to the sliding groove through a snap-fit ​​plate. The locking block is symmetrically arranged inside the connector. When the sliding block slides downward, its inclined structure pushes the locking block to move inward into the sliding groove, thereby locking the position of the snap-fit ​​plate.

[0008] The beneficial effects of this utility model are:

[0009] 1. When connecting the connector and the joint, the sliding block moves up and down, pushing the locking block to move inward into the sliding groove. One end of the locking block locks the snap-fit ​​plate, achieving "one-click locking". Through the mechanical engagement of the locking block and the snap-fit ​​plate, the vibration and impact resistance of the connector and the joint are significantly improved. At the same time, the "one-click sliding" operation achieves quick locking, greatly improving assembly efficiency.

[0010] 2. During long-term use, the position of the locking block is locked by the sliding block to ensure that the locking block always presses against the snap plate, avoiding accidental unlocking due to external force collision and reducing the failure rate.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, a plug is fixedly connected to the bottom of the connector, the plug is snapped into the inside of the connector, a metal core is fixedly connected to one side of the inside of the connector, and the inside of the plug and the metal core are snapped together.

[0013] The advantages of adopting the above-mentioned further solution are that it can quickly and accurately locate the installation position of the connector, reduce installation errors, and at the same time ensure that the conductive contacts are in close contact, with a large contact area and uniform pressure, reduce contact resistance, improve signal transmission stability, and achieve effective protection of the contacts to avoid component damage.

[0014] Preferably, the connector has symmetrical mounting grooves at both ends, the locking block slides left and right inside the mounting grooves, and limit plates are symmetrically fixedly connected to both sides of the locking block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the limiting plate limits the sliding direction and position of the locking block as it slides left and right inside the mounting groove, ensuring the accuracy of the moving direction of the locking block and effectively guaranteeing the locking effect between the locking block and the snap-fit ​​plate.

[0016] Preferably, guide rods are fixedly connected to the four corners inside the joint, and springs are provided on the outside of the guide rods. The sliding block slides on the outside of the guide rods, and the upper and lower ends of the springs are fixedly connected to the bottom of the sliding block and the joint, respectively.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the guide rod limits the movement direction of the sliding block, ensuring the accuracy of the movement direction of the sliding block and ensuring the limiting effect of the sliding block on the locking block. The spring provides a continuous upward preload to the sliding block, ensuring that the locking block always presses against the snap-fit ​​plate and avoids loosening due to long-term vibration.

[0018] Preferably, the ignition coil body is fixedly connected to the bottom of the mounting base.

[0019] The advantages of adopting the above-mentioned further solution are that the mounting base, connector and ignition coil body are integrated into a compact design, occupy little space, and are compatible with the ignition coil layout of various vehicle models.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] During the connection process between the connector and the fitting, the plug at the bottom of the connector engages with the inside of the fitting. Simultaneously, the locking plate at the bottom of the connector slides into the sliding groove. As the sliding block moves up and down, its inclined side contacts the locking block, pushing it inward into the sliding groove. One end of the locking block engages the locking plate, achieving a "one-click locking" effect. This resists vibration and external impact, preventing fatigue damage caused by external vibrations and other factors that could lead to loosening of the connection. Compared to traditional threaded connections, this improves the convenience and efficiency of the connection. Attached Figure Description

[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] Please see Figures 1-4 As shown, this embodiment provides a quick connector device for automotive ignition coils, including a mounting base 1. A connector 11 is fixedly connected to one end of the top of the mounting base 1, and a connecting seat 13 is provided on the top of the connector 11. Considering that the connection efficiency of ignition coil connectors in traditional technology is low and that the buckle is prone to fatigue damage due to vibration and other factors during long-term use, resulting in loosening of the connection, a locking component 2 is provided inside the connector 11. The locking component 2 includes a sliding block 21. A sliding groove 22 is symmetrically arranged inside the connector 11. The connecting seat 13 is slidably connected to the sliding groove 22 through a snap-fit ​​plate 23. A locking block 25 is symmetrically arranged inside the connector 11. When the sliding block 21 slides downward, its inclined structure pushes the locking block 25 to move inward to the sliding groove 22, thereby locking the position of the snap-fit ​​plate 23 and forming a mechanical lock for the engagement of the connecting seat 13 and the connector 11, resisting the influence of vibration and external force impact on the engagement connection and ensuring the stability of the connection.

[0032] In summary, the improvement of this embodiment lies in:

[0033] On the one hand, the connector 13 and the connector 11 are connected by a snap-fit ​​mechanism, which effectively ensures the connection efficiency and ease of operation of the connector. On the other hand, the position of the locking block 25 is limited or unlocked by the sliding block 21 sliding up and down, so that the locking block 25 can quickly lock the snap-fit ​​plate 23 at the bottom of the connector 13 firmly in the sliding groove 22. When the connector 11 is connected or separated, the locking or unlocking can be completed quickly by simply pushing the sliding block 21 up and down, which greatly shortens the installation time and improves the convenience and efficiency of connector connection.

[0034] Based on the above, other structures also need to be disclosed in detail, such as:

[0035] To achieve rapid positioning when connecting the plug and socket, and to ensure accurate connection position and avoid positional deviations that could affect subsequent locking, a plug 14 is fixedly connected to the bottom of the connector 13. The plug 14 is snapped into the interior of the connector 11, and a metal ferrule 12 is fixedly connected to one side of the interior of the connector 11. The inner side of the plug 14 and the metal ferrule 12 are snapped together. Through the snapping of the plug 14 with the connector 11 and the metal ferrule 12, the installation position of the connector 13 can be quickly and accurately positioned, reducing installation errors. At the same time, it ensures tight contact of the conductive contacts, a large contact area and uniform pressure, reduces contact resistance, and improves signal transmission stability. Furthermore, the metal ferrule 12 snaps into the interior of the plug 14, effectively protecting the contacts and preventing component damage.

[0036] In order to achieve quick locking between connector 11 and connecting seat 13, mounting grooves 24 are symmetrically arranged at both ends of the connector 11. Locking block 25 slides left and right inside the mounting groove 24. Guide rods 27 are fixedly connected at the four corners of the connector 11. Springs 28 are arranged on the outside of the guide rods 27. Sliding block 21 slides on the outside of the guide rods 27. The upper and lower ends of the springs 28 are fixedly connected to the bottom of the sliding block 21 and the connector 11, respectively. When the connector 13 is connected to the connector 11, when the snap-fit ​​plate 23 enters the sliding groove 22, the sliding block 21 is first manually slid downwards. Then, the bottom bevel of the snap-fit ​​plate 23 presses against the locking block 25, pushing the locking block 25 to move towards the sliding block 21 inside the mounting groove 24, fully opening the sliding groove 22 channel, allowing the snap-fit ​​plate 23 to enter the bottom of the sliding groove 22. After the position of the snap-fit ​​plate 23 is determined, the downward force on the sliding block 21 is released. Under the elastic force of the spring 28, the sliding block 21 is pushed upwards to reset. At this time, the bevel on one side of the sliding block 21 presses against the locking block 25, pushing the locking block 25 to move towards the sliding groove 22 inside the mounting groove 24. One end of the locking block 25 is placed inside the sliding groove 22, realizing quick locking of the lower end of the snap-fit ​​plate 23. At the same time, the sliding block 21 is locked in position by the spring 28, ensuring the stability of the connector 11 connection. Locking or unlocking can be quickly completed by simply pushing the sliding block 21 up and down, greatly shortening the installation time. During the process, the guide rod 27 limits the movement direction of the sliding block 21, ensuring the accuracy of the sliding block 21's movement direction and guaranteeing the locking effect of the sliding block 21 on the locking block 25. The spring 28 provides a continuous upward preload to the sliding block 21, ensuring that the locking block 25 always presses against the snap-fit ​​plate 23, preventing loosening due to long-term vibration. Furthermore, symmetrically fixed limit plates 26 are connected to both sides of the locking block 25, limiting the sliding direction and position of the locking block 25 as it slides left and right within the mounting groove 24. This ensures the accuracy of the locking block 25's movement direction, effectively guaranteeing the locking effect between the locking block 25 and the snap-fit ​​plate 23, while preventing the locking block 25 from moving out of the mounting groove 24, avoiding accidental unlocking due to external impact, and reducing the failure rate.

[0037] The mounting base 1 is fixedly connected to the ignition coil body 3 at the bottom. The mounting base 1, connector 11 and ignition coil body 3 are integrated into the design, which has a compact structure, occupies little space and is suitable for the ignition coil layout of various vehicle models.

[0038] In summary, the working principle of this solution is as follows:

[0039] When the connector 13 is connected to the connector 11, place the connector 13 on top of the connector 11 and slowly move it down to engage. First, manually slide the sliding block 21 downwards to compress the spring 28. Then, the plug 14 enters the connector 11 and engages with the metal ferrule 12. When the snap-fit ​​plate 23 enters the sliding groove 22, its bottom bevel presses against the locking block 25, pushing the locking block 25 towards the sliding block 21 within the mounting groove 24, fully opening the sliding groove 22 channel. This allows the snap-fit ​​plate 23 to enter the bottom of the sliding groove 22. Once the position of the snap-fit ​​plate 23 is determined... At this point, the downward force on the sliding block 21 is released, and under the elastic force of the spring 28, the sliding block 21 is pushed upward to return to its original position. At this time, the inclined surface on one side of the sliding block 21 presses against the locking block 25, pushing the locking block 25 to move from the mounting groove 24 into the sliding groove 22. One end of the locking block 25 is placed inside the sliding groove 22, achieving quick locking of the lower end of the snap-fit ​​plate 23. At the same time, the sliding block 21 locks the position of the locking block 25 under the action of the spring 28, ensuring the stability of the connector 11 connection. Locking or unlocking can be quickly completed by simply pushing the sliding block 21 up and down, greatly shortening the installation time. During the installation process, the guide rod 27 limits the movement direction of the sliding block 21, ensuring the accuracy of the movement direction of the sliding block 21 and ensuring the limiting effect of the sliding block 21 on the locking block 25. The spring 28 provides a continuous upward preload force for the sliding block 21, ensuring that the locking block 25 always presses against the snap-fit ​​plate 23, avoiding loosening due to long-term vibration. Furthermore, the locking block 25 is symmetrically fixedly connected to the limiting plates 26 on both sides, so that the limiting plates 26 limit the sliding direction and position of the locking block 25 as it slides left and right inside the mounting groove 24, ensuring the accuracy of the moving direction of the locking block 25, effectively ensuring the locking effect between the locking block 25 and the snap-fit ​​plate 23, while preventing the locking block 25 from moving out of the mounting groove 24, avoiding accidental unlocking due to external force collision, and reducing the failure rate.
