[0038] Please refer to Figure 1-8 , the present utility model provides a technical solution: an electrode connector for automobile battery detection, including an insulating protective shell 1 and a conductor. The lower end of the insulating protective shell 1 is an open structure, and the conductor is a tubular structure with openings at both ends. The conductor is installed in the lower opening of the insulating protective shell 1, and one opening of the conductor is opposite to the lower opening of the protective shell. A gas guide pipe 2 is connected to the top of the insulating protective shell 1, and the gas guide pipe 2 is communicated with the inside of the insulating protective shell 1.

[0039] The conductor is a tubular structure, and its inner diameter can be designed according to the electrode sizes of automobile batteries of different specifications. The insulating protective shell 1 is wrapped outside the conductor to protect the conductor. The conductor can be connected to a wire and extend outside the insulating protective shell 1 for connection to a power-consuming device, and can be used as the holding part of the operator. Among them, the top of the insulating protective shell 1 is connected to the gas guide pipe 2, and an inert gas source can be connected through the gas guide pipe 2, and inert gas can be filled into the inside of the insulating protective shell 1 through the gas guide pipe 2;

[0040] During use, first connect the inert gas source to the air duct 2 through a pipeline and turn on the gas source. The inert gas will enter the insulation protection shell 1 through the air duct 2 and flow outwards from the conductive body. Then, the operator holds the insulation protection shell 1 with the lower end of the insulation protection shell 1 facing downwards, that is, the lower end of the conductive body facing downwards, and sleuth the conductive body on the electrode of the automotive battery. Since the conductive body is located inside the insulation protection shell 1 and the inside of the conductive body is also filled with inert gas to form a low-oxygen environment, in case of arc ablation, the low-oxygen environment can effectively reduce the oxidation degree of the arc ablation point and reduce the impact of the arc ablation on the electrode of the automotive battery.

[0041] In this embodiment, the conductive body includes an inner tube body 3 and an outer tube body 4. The outer tube body 4 is fixedly connected to the insulation protection shell 1. The inner tube body 3 is arranged inside the outer tube body 4, and the outer wall of the inner tube body 3 is in contact with the inner wall of the outer tube body 4.

[0042] The outer tube body 4 serves as a fixing part connected to the insulation protection shell 1. The inner tube body 3 is arranged inside the outer tube body 4. The outer diameter of the inner tube body 3 should be the same as the inner diameter of the outer tube body 4 so that the two can be closely matched and can be detached by sliding, and they are connected in a detachable manner. The inner tube body 3 with a corresponding inner diameter can be selected according to the electrode sizes of different specifications of automotive batteries.

[0043] In this embodiment, air guide holes 5 are opened through both ends of the inner tube body 3.

[0044] The inner tube body 3 is in contact with the electrode of the automotive battery to form a closed structure. The continuous charging of inert gas will cause the air pressure inside the insulation protection shell 1 to increase. By designing the air guide holes 5, the air guide holes 5 can serve as an air guiding structure to discharge the inert gas entering the insulation protection shell 1 outwards, avoiding the increase of air pressure inside the insulation protection shell 1 due to the continuous charging of inert gas. At the same time, it can form heat exchange with the inner tube body 3 and can take away the heat generated by the inner tube body 3 due to conduction or arc burn through the flow of inert gas.

[0045] In this embodiment, a plurality of strip-shaped grooves 6 are opened on the inner wall of the inner tube body 3. Both ends of the strip-shaped grooves 6 extend towards both ends of the inner tube body 3 and extend out of both ends.

[0046] Strip-shaped grooves 6 are opened on the inner wall of the inner tube body 3. The strip-shaped grooves 6 will serve as another air guiding structure and heat conducting structure. Moreover, the inner tube body 3 can be driven to rotate by rotating the protection shell. When the inner tube body 3 rotates, the side wall of the air guiding groove can scrape the surface of the electrode of the automotive battery, which can play a certain cleaning role, improve the contact effect between the inner tube body 3 and the electrode of the automotive battery, and the sundries cleaned can enter the strip-shaped grooves 6 and then be discharged outwards due to the flow of inert gas.

[0047] In this embodiment, the strip-shaped grooves 6 are spiral-shaped extending along the inner wall.

[0048] The spiral structure can increase the length of the strip groove 6, extend the flow channel of the inert gas, so as to prolong the action time between the inert gas and the inner tube body 3 and the electrodes of the automotive battery, and improve the heat exchange and cooling effect.

[0049] In this embodiment, a plurality of first limiting grooves 7 extending axially are formed on the inner wall of the outer tube body 4, and first limiting ridges 8 matching with the plurality of first limiting grooves 7 are formed on the outer wall of the inner tube body 3.

[0050] The first limiting grooves 7 and the first limiting ridges 8 cooperate with each other to serve as a rotational limiting structure between the outer tube body 4 and the inner tube body 3.

[0051] In this embodiment, a partition 9 is arranged inside the insulating protective shell 1 and transversely cuts off between the air guide pipe 2 and the lower opening;

[0052] A plurality of through holes 10 communicating with both sides of the partition 9 are formed on the partition 9;

[0053] A sealing plate 17 is arranged on one side of the partition 9 close to the air guide pipe 2, the sealing plate 17 covers the plurality of through holes 10, and a gap is formed between the edge of the partition 9 and the inner wall of the insulating protective shell 1. A push rod 11 penetrating downward and protruding from the bottom surface of the partition 9 is arranged at the center of the sealing plate 17.

[0054] The sealing plate 17 can maintain the fitting state with the partition 9 under the action of its own gravity, that is, maintain the covering state of the through holes 10 to make the through holes 10 in a closed state. After being connected to the electrodes of the automotive battery, the push rod 11 will push the sealing plate 17 away from the partition 9 on the top surface of the electrodes of the automotive battery, that is, make the through holes 10 in a communicating state. In this state, the inert gas can be discharged outward from the through holes 10 through the gap between the side of the sealing plate 17 and the inner wall of the insulating protective shell 1 above the sealing plate 17. After being separated from the electrodes of the automotive battery, the sealing plate 17 will return to the fitting state with the partition 9 under the action of its own gravity and close the through holes 10;

[0055] Using the above structural principle, the gas source can be kept filling the insulating protective shell 1 with inert gas, and the through holes 10 can be closed under the dual action of air pressure and the self - gravity of the sealing plate 17, which can reduce the steps of separately opening the gas source and reduce the operation amount to a certain extent.

[0056] In this embodiment, a flexible sealing sheet 12 is connected to the bottom surface of the sealing plate 17, and the bottom surface of the flexible sealing sheet 12 protrudes from the bottom surface of the sealing plate 17.

[0057] Then, the flexible sealing sheet 12 is used as a sealing structure. The flexible sealing sheet 12 can be made of flexible silica gel or flexible rubber, which can effectively improve the sealing effect.

[0058] In this embodiment, spherical grooves 13 are formed at the upper ends of several through holes 10, and spherical protrusions 14 that face the several through holes 10 and protrude downward are provided on the bottom surface of the flexible sealing sheet 12.

[0059] The spherical groove 13 and the spherical protrusion 14 form a sealing structure for blocking the upper end of the through hole 10. The two extend through spherical contact as the contact surface between the flexible sealing sheet 12 and the partition plate 9, increasing the contact area between the two and improving the sealing effect.

[0060] In this embodiment, several second limiting grooves 15 are formed at the edge of the sealing plate 17, and second limiting ribs 16 that cooperate with the several second limiting grooves 15 are provided on the inner wall of the insulating protective shell 1.

[0061] The sealing plate 17 has a fixed track during sliding, so that the spherical groove 13 and the spherical protrusion 14 can maintain a relatively cooperative state, improving the structural stability.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
