Abstract

This utility model discloses an electric motorcycle power connector with an assist wrench, relating to the field of electric motorcycle power connectors. In this utility model, an assist wrench is added to the line-end connector. When the line-end connector and the board-end connector are inserted, the line-end connector socket is first aligned and pre-inserted with the board-end connector socket. The sliding limit posts on both sides of the board-end connector are then inserted into the slide rail entrance of the assist wrench. The end of the assist wrench is then manually pushed, causing it to rotate around the fulcrum connecting post. As the assist wrench rotates, the sliding guide action between the slide rail and the sliding limit posts pulls the board-end connector towards the line-end connector, thus assisting in the insertion process. This allows the line-end connector to be easily inserted into the board-end connector. At this time, the assist wrench is pre-pressed onto the line-end connector, and the notch at the end of the assist wrench is precisely engaged with the fixing protrusion at the tail end of the line-end connector, enabling the assist wrench to limit and lock the line-end connector and the board-end connector.

Description

Technical Field

[0001] This utility model belongs to the field of electric motorcycle power connectors, and more specifically, it relates to an electric motorcycle power connector with an assist wrench. Background Technology

[0002] Electric motorcycle power connectors are key components used to connect the battery to the vehicle in electric motorcycles (including electric two-wheelers). During vehicle use, they provide efficient and stable current transmission, high shock resistance, high protection performance, long mating life, and convenient and labor-saving plugging and unplugging. However, existing power connectors have the following shortcomings:

[0003] 1. When connecting or disconnecting the connector wire end and board end, you should use your hands to insert or pull it out. However, when the current that the connector is designed to carry exceeds 60A, the insertion and extraction force required by the corresponding terminal also needs to be increased accordingly. Therefore, when inserting or pulling the connector, you will feel a lot of effort.

[0004] 2. Currently, most power connectors on the market use a button method to fix the male and female ends of the connector. During intense driving, severe bumps or other situations may cause the male and female ends of the connector to detach, resulting in a risk of power failure.

[0005] Therefore, this application designs an electric motorcycle connector with an assist wrench to solve the above problems. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an electric motorcycle power connector with an assist wrench to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an electric motorcycle power connector with an assist wrench, comprising a wire end connector, a plate end connector, and an assist wrench. A fulcrum connecting post is fixedly installed on the wire end connector. The assist wrench is rotatably connected to the fulcrum connecting post through a connecting hole. A slide rail is provided on the front side of the assist wrench. A sliding limit post that can slide and engage with the slide rail is fixedly installed on the plate end connector. A notch is provided at the end of the assist wrench. A fixing protrusion that can engage with the notch is fixedly installed on the wire end connector.

[0009] Furthermore, the wire end connector is also equipped with a telescopic limiting post, and the assist wrench is provided with a limiting hole that can engage with the telescopic limiting post.

[0010] Furthermore, the assist wrench has a U-shaped structure, and both sides of the assist wrench are provided with notches and slide rails. The corresponding wire end connectors are fixedly installed with fulcrum connecting posts and fixing protrusions on both sides, and the plate end connectors are fixedly installed with sliding limit posts on both sides.

[0011] Furthermore, the wire connector includes a wire connector body and a power cable. The wire connector body has a signal male pin and a power male terminal installed inside. One end of the signal male pin is soldered to a signal line. One end of the power cable is provided with a copper lug. The copper lug is installed close to one end of the power male terminal, and the copper lug and the power male terminal are locked and fixed by a Phillips screw.

[0012] Furthermore, a sealing ring is fixedly installed on the outer ring of the plug-in end of the wire connector body, and a power terminal anti-contact cap is plugged into the plug-in end of the power male terminal.

[0013] Furthermore, an inner mold with rubber coating is fitted onto one end of the connector body that connects to the power cable, and an outer mold with rubber coating is fixedly installed on the surface of the inner mold with rubber coating.

[0014] Furthermore, the board-end connector includes a board-end connector body, and a power female terminal and a signal female pin are fixedly inserted inside the board-end connector body. The power female terminal is locked and fixedly connected to the board-end connector body by screws.

[0015] Furthermore, one end of the board connector body is laterally plugged in and has a terminal fixing bracket extending to the position of the power female terminal, and the outer wall of the power female terminal is provided with a limiting plane that can be tightly attached to the terminal fixing bracket.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, an assist wrench is added to the wire-end connector. When the wire-end connector and the board-end connector are inserted, the wire-end connector socket is first aligned with the board-end connector socket for pre-insertion, and the sliding limit posts on both sides of the board-end connector are inserted into the slide rail inlet of the assist wrench. Then, the end of the assist wrench is pushed by hand, causing the assist wrench to rotate around the fulcrum connecting post. When the assist wrench rotates, the sliding guide action between the slide rail and the sliding limit post pulls the board-end connector towards the wire-end connector, thereby assisting the insertion effect and allowing the wire-end connector to be easily inserted into the board-end connector. Similarly, when the wire-end connector is pulled out, the end of the assist wrench is pushed in the opposite direction by hand, causing the assist wrench to reverse. At this time, the assist wrench pushes the board-end connector away from the wire-end connector through the sliding guide action between the slide rail and the sliding limit post, making it easier and less strenuous to pull out the wire-end connector.

[0018] 2. In this utility model, when the wire-end connector is inserted into the board-end connector through the assist wrench, the assist wrench is pre-pressed onto the wire-end connector, and the notch at the end of the assist wrench is just engaged with the fixing protrusion at the tail end of the wire-end connector. In this state, the sliding limit posts on both sides of the board-end connector are tightly locked in the slide rail of the assist wrench and cannot be disengaged. The combination of the notch at the end of the assist wrench and the fixing protrusion at the tail end of the wire-end connector serves as a secondary lock. Thus, through the connection and limitation of the assist wrench, the fixing protrusion, and the sliding limit posts, the connection between the wire-end connector and the board-end connector is reinforced and locked, improving the stability of the connection between the wire-end connector and the board-end connector and preventing the wire-end connector and the board-end connector from loosening during the bumpy ride of the electric motorcycle.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-5 As shown, this utility model is an electric motorcycle power connector with an assist wrench, including a wire end connector, a board end connector, and an assist wrench 3. A fulcrum connecting post 4 is fixedly installed on the wire end connector. The assist wrench 3 is rotatably connected to the fulcrum connecting post 4 through a connecting hole. A slide rail 8 is provided on the front side of the assist wrench 3. A sliding limit post 9 that can slide and engage with the slide rail 8 is fixedly installed on the board end connector. A notch 5 is provided at the end of the assist wrench 3. A fixing protrusion 7 that can engage with the notch 5 is fixedly installed on the wire end connector.

[0030] The power-assisted wrench 3 has a U-shaped structure, with recesses 5 and slide rails 8 on both sides. Correspondingly, the wire connector has fulcrum connecting posts 4 and fixing protrusions 7 fixedly installed on both sides, and the board connector has sliding limiting posts 9 fixedly installed on both sides. The slide rails 8 are arc-shaped tracks. When connecting the wire connector and the board connector, first align the wire connector socket with the board connector socket for pre-connection, and then allow the sliding limiting posts 9 on both sides of the board connector to enter the slide rail 8 entrance on the power-assisted wrench 3. Then, manually push the end of the power-assisted wrench 3 (from left to right) to make the power-assisted wrench 3... The fulcrum connecting post 4 rotates at the fulcrum, while the assist wrench 3, when rotating, pulls the board end connector towards the wire end connector through the sliding guide action between the slide rail 8 and the sliding limit post 9, thereby assisting in the insertion effect and allowing the wire end connector to be easily inserted into the board end connector. Similarly, when pulling out the wire end connector, push the end of the assist wrench 3 in the opposite direction (from right to left) by hand, causing the assist wrench 3 to reverse. At this time, the assist wrench 3, through the sliding guide action between the slide rail 8 and the sliding limit post 9, pushes the board end connector away from the wire end connector, making it easier and less strenuous to pull out the wire end connector.

[0031] Furthermore, when the wire connector is inserted into the board connector via the power wrench 3, the power wrench 3 is pre-pressed onto the wire connector, and the notch 5 at the end of the power wrench 3 is precisely engaged with the fixing protrusion 7 at the tail end of the wire connector. In this state, the sliding limit posts 9 on both sides of the board connector are tightly locked in the slide rail 8 of the power wrench 3 and cannot be disengaged. The combination of the notch 5 at the end of the power wrench 3 and the fixing protrusion 7 at the tail end of the wire connector serves as a secondary structural lock. Thus, through the connection and limitation of the power wrench 3, the fixing protrusion 7, and the sliding limit posts 9, the connection between the wire connector and the board connector is reinforced and locked, improving the stability of the connection between the wire connector and the board connector and preventing the wire connector and the board connector from loosening during the bumpy ride of the electric motorcycle.

[0032] Specifically, the wire-end connector is also equipped with a telescopic limiting post 6, and the assist wrench 3 is provided with a limiting hole that can engage with the telescopic limiting post 6. The telescopic limiting post 6 is slidably inserted into the wire-end connector, and a return spring is installed on the inner end of the telescopic limiting post 6. When the wire-end connector is not in the docking state, the telescopic limiting post 6 is inserted into the limiting hole on the assist wrench 3, thereby cooperating with the fulcrum connecting post 4 to position the assist wrench 3 through two positioning points, preventing the assist wrench 3 from rotating or shaking on the wire-end connector. When assisted docking is required, the telescopic limiting post 6 is pressed down to contact the limiting position of the telescopic limiting post 6 on the assist wrench 3, so that the assist wrench 3 can be rotated to connect the wire-end connector and the board-end connector.

[0033] Specifically, the wire-end connector includes a wire-end connector body 1 and a power cable 18. The wire-end connector body 1 has a signal male pin 15 and a power male terminal 16 installed inside. One end of the signal male pin 15 is soldered to a signal line 19. One end of the power cable 18 is provided with a copper lug 17, which is installed close to one end of the power male terminal 16, and the copper lug 17 and the power male terminal 16 are locked and fixed by a Phillips screw 11. The board-end connector includes a board-end connector body 2. The board-end connector body 2 has a power female terminal 20 and a signal female pin 21 fixedly inserted inside. The power female terminal 20 is locked and fixed to the board-end connector body 2 by screws.

[0034] When the wire-end connector and the board-end connector are mated, the wire-end connector body 1 and the board-end connector body 2 are tightly mated, and the power male terminal 16 is inserted into the power female terminal 20, and the signal male pin 15 is inserted into the signal female pin 21, thereby realizing the signal and circuit connection between the wire-end connector and the board-end connector.

[0035] Specifically, a sealing ring 12 is fixedly installed on the outer ring of the insertion end of the wire connector body 1. When the wire connector and the board connector are mated, the sealing ring 12 is clamped between the wire connector body 1 and the board connector body 2, thereby improving the sealing performance of the connection between the wire connector body 1 and the board connector body 2, preventing rainwater from seeping into the joint between the wire connector body 1 and the board connector body 2, and improving the waterproof performance and safety of the connector.

[0036] Specifically, the power male terminal 16 is fitted with a power terminal anti-touch cap 14. The power terminal anti-touch cap 14 can isolate and protect the power male terminal 16 from electric shock risk caused by human contact. Before the line connector and board connector are connected, the power terminal anti-touch cap 14 must be removed so that the power male terminal 16 and the power female terminal 20 can be properly connected.

[0037] Specifically, the end of the connector body 1 that connects to the power cable 18 is fitted with an inner mold 10, and an outer mold 13 is fixedly mounted on the surface of the inner mold 10. The inner mold 10 is not made of flexible plastic, so that the inner mold 10 is tightly connected to the connection points of electronic components such as the signal male pin 15, the power male terminal 16, the copper lug 17, and the signal line 19, ensuring the stability of the connection. The outer mold 13 is not made of rigid plastic, and provides physical protection through the plastic shell to prevent damage to the internal electronic components from the external environment (such as vibration, humidity, and temperature changes).

[0038] Specifically, one end of the board connector body 2 is laterally inserted and installed with a terminal fixing bracket 22 extending to the position of the power female terminal 20. The outer wall of the power female terminal 20 is provided with a limiting plane that can be tightly attached to the terminal fixing bracket 22. The terminal fixing bracket 22 cooperates with the limiting plane on the outer wall of the power female terminal 20 to clamp and fix the power female terminal 20, preventing the power female terminal 20 from rotating when tightened by screws, making the tightening process of the power female terminal 20 more convenient.
