Description
Technical Field
[0001] This utility model relates to the field of power clip technology, and more specifically to an automotive emergency jump starter clip. Background Technology
[0002] Existing car jump starter products mainly consist of a power clip and wiring components, used to provide emergency starting power to car batteries. However, existing technologies have several problems; for example, insufficient waterproof and dustproof performance. Traditional power clips have a simple connection between the upper shell and lower cover, and the sealing structure is imperfect, making the internal circuitry susceptible to moisture damage in rain or dusty environments, affecting their safe service life. Wiring is also not safe enough; most products lack effective protection for the clips and terminals, making it easy for users to accidentally touch live parts, posing a risk of electric shock. Furthermore, the distinction between red and black wires is not clear or standardized, increasing the possibility of misoperation. Additionally, the internal PCB layout of existing power clips often uses relays arranged side-by-side, occupying a large space and resulting in a bulky overall size, making it inconvenient for users to hold and difficult to plug and unplug. Therefore, there is an urgent need for a compact, waterproof, safe, and easy-to-handle car jump starter clip to improve safety and convenience. Utility Model Content
[0003] In view of this, the present invention provides an emergency jump starter clip for automobiles.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A car emergency jump starter clip includes a clip body and a first wire and a second wire extending from the clip body. The ends of the first and second wires are respectively provided with clamps. The clip body includes an upper shell and a lower cover. The lower cover has a sealing groove on its outer side, and a sealing ring is provided within the sealing groove. The upper shell has a sealing rib corresponding to the sealing groove. During installation, the sealing rib is embedded in the sealing groove and presses against the sealing ring, thereby achieving a waterproof seal. A connecting terminal is provided at the end of the clip body away from the wires. The connecting terminal is fitted with sealing silicone to achieve a waterproof seal when inserted into a power interface. A PCB board is provided inside the clip body. The PCB board connects the connecting terminal to the first and second wires. Two relays are provided on the PCB board, arranged linearly along the wire extension direction, thereby reducing the space occupied by the PCB board and reducing the size of the clip body.
[0006] In a preferred embodiment, the bottom of the lower cover is provided with multiple threaded holes, and a sealing ring is provided in the threaded holes. The upper shell and the lower cover are connected and fixed by screws to achieve overall sealing and waterproofing.
[0007] In a preferred embodiment, the outer side of the connecting terminal is provided with multiple layers of protruding tabs, and the corresponding positions of the upper shell and the lower cover are provided with slots that match the tabs. The connecting terminal is embedded in the slots through the tabs and is fixed by the upper shell and the lower cover when they are closed.
[0008] In a preferred embodiment, the connecting terminal is covered with a sealing silicone sealant. When the connecting terminal is inserted into the power interface, the sealing silicone sealant adheres to the power interface to achieve a sealed and waterproof seal.
[0009] In a preferred embodiment, the connecting terminal has multiple protrusions on its outer side, and the sealing silicone has fixing holes that match the protrusions. After the sealing silicone is fitted into the connecting terminal, it engages with the protrusions through the fixing holes to form a locking mechanism, thus preventing the sealing silicone from falling off.
[0010] In a preferred embodiment, the two relays are electrically connected to the first wiring terminal and the second wiring terminal respectively, and are used to control the conduction and disconnection of the first wiring terminal and the second wiring terminal.
[0011] In a preferred embodiment, the relays are arranged in a straight line along the wiring direction, rather than side by side, to reduce the lateral space occupied by the PCB board.
[0012] In the preferred technical solution, the PCB board size is reduced by arranging the relays in a straight line, thereby reducing the size of the power clamp body and making it easier for users to hold and plug and unplug.
[0013] In a preferred embodiment, the upper shell and lower cover are fixed using a combination of snap-fit and screw engagement to improve assembly firmness and sealing performance.
[0014] In a preferred embodiment, the upper shell and lower cover of the power clamp body are made of insulating material, and a gripping part is provided on the outer surface to improve safety and comfort of use.
[0015] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:
[0016] The power clamp employs a multi-layered sealing structure, combining an upper shell and lower cover with sealing grooves, sealing rings, sealing ribs, and sealing silicone, to protect the power clamp body and connecting terminals from rain and dust, effectively improving circuit reliability and lifespan. The clamps at the ends of the first and second terminals are made of insulating material and feature grips for safe operation and reduced risk of accidental contact. Relays on the PCB are arranged linearly along the wiring direction, minimizing lateral space occupation and reducing the overall size of the power clamp body, making it easier for users to hold and plug / unplug. Two relays control the conduction and disconnection of the first and second terminals respectively, achieving effective on / off control while ensuring circuit safety and reliability during high-current discharge or continuous use. The upper shell and lower cover are fixed together with screws and clips, resulting in a simple, robust, and reliable structure that facilitates production and assembly while ensuring overall sealing performance.

[0026] A car jump starter clip, please refer to Figure 1-4 The device includes a power clamp body 1, which consists of an upper shell 11 and a lower cover 12. The lower cover 12 has an annular sealing groove 13 on its outer side, into which a sealing ring 14 is embedded. The upper shell 11 has protruding sealing ribs 15 at positions corresponding to the lower cover 12. During installation, the sealing ribs 15 are embedded in the sealing groove 13 and the sealing ring 14 is pressed together, thus achieving a sealed and waterproof design for the power clamp body 1. The lower cover 12 has four threaded holes 18 at its bottom, each containing a sealing ring 19. The upper shell 11 and lower cover 12 are fixedly connected by screws, making the overall structure both robust and waterproof.
[0027] Furthermore, the end of the power clamp body 1 furthest from the wires 2 and 3 is provided with a connecting terminal 6 for insertion into the car starter power interface. The connecting terminal 6 is covered with a sealing silicone 9, which, when inserted into the power interface, fits tightly against the interface, achieving a waterproof seal. The outer side of the connecting terminal 6 has multiple layers of protrusions 10, and the sealing silicone 9 has fixing holes 20 that match the protrusions 10, forming a locking position after the connecting terminal 6 is inserted, preventing the sealing silicone 9 from falling off. The upper shell 11 and lower cover 12 have corresponding slots 8. After the connecting terminal 6 is inserted into the slot 8 via the locking protrusions 7, the upper and lower shells are closed and secured with screws, firmly fixing the connecting terminal 6 to the power clamp body 1.
[0028] Furthermore, a first wire 2 and a second wire 3 extend from the power clamp body 1, with their ends connected to clamps 21 respectively. Clamps 21 are used to clamp the positive and negative terminals of the car battery. Clamps 21 are covered with insulating material and have a gripping part 24 on the outside. The gripping part 24 has a recessed texture or a raised block structure to facilitate user operation and prevent accidental contact with conductive parts, thus avoiding safety accidents.
[0029] Furthermore, the power clamp body 1 contains a PCB board 16 for connecting the connecting terminal 6 to the first wiring 2 and the second wiring 3. Two relays 17 are mounted on the PCB board 16 to control the on / off state of the first wiring 2 and the second wiring 3. The relays 17 are arranged in a straight line along the wiring extension direction, rather than side-by-side, to reduce the lateral area occupied by the PCB board 16, thereby reducing the volume of the power clamp body 1 and improving user convenience. The relays 17 are electrically connected to the first wiring 2 and the second wiring 3 via PCB pads. When the relay 17 is energized, the corresponding wiring is connected; when the relay is de-energized, the wiring is disconnected. The PCB board 16 is small in size and has compact wiring, while ensuring safety and reliability when high current is passed. The soldering and wiring of the PCB board 16 and the connecting terminal 6 both use highly conductive copper foil and thick film design to ensure stable current transmission and reduce heat generation.
[0030] Furthermore, the upper shell 11 and lower cover 12 are secured with screws and clips, ensuring a robust and reliable overall structure. The upper shell 11 and lower cover 12 are made of insulating material to prevent external conductive objects from contacting the internal circuitry, thus enhancing safety. The combination of the sealing silicone 9, sealing ring 14, sealing groove 13, and sealing ring 19 enables the entire power clamp body 1 to meet IP65 waterproof and dustproof requirements, meaning it is unaffected by water or dust intrusion in typical rainy environments and during car startup.
[0031] Furthermore, during use, the user inserts the connecting terminal 6 into the car starter power interface, and the sealing silicone 9 automatically adheres to the interface to form a waterproof seal. Then, the clamp 21 clamps the positive and negative terminals of the car battery respectively. The first wiring 2 and the second wiring 3 are connected via relay 17 to enable emergency starting of the car. After use, the power to relay 17 is disconnected, the first wiring 2 and the second wiring 3 are disconnected, and the clamp 21 can be safely removed. The entire structural design ensures simple operation, safety and reliability, and easy hand-held insertion and removal. It is also waterproof and dustproof, with a small PCB size and a reasonable relay arrangement, facilitating production and maintenance. The power clamp body 1 adopts an upper shell 11 + lower cover 12 structure, combined with a sealing groove 13, sealing ring 14, sealing rib 15, and sealing ring 19 to achieve a waterproof seal. The connecting terminal 6 is fitted with sealing silicone 9, which adheres to the power interface, providing waterproof and dustproof protection.
[0032] The first connector 2 and the second connector 3 have insulated clamps 21 with gripping textures or protrusions 24 for safe and convenient operation. The PCB board 16 is compactly arranged, with relays 17 arranged in a straight line along the wiring direction to control wiring continuity and reduce size. The upper shell 11 and lower cover 12 are made of insulated material, ensuring reliable overall fixation and making them suitable for automotive emergency starting applications.
[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
