Description

Technical Field

[0001] The present invention relates to the technical field of battery connectors, and particularly to a battery connector assembly. Background Art

[0002] At present, with the rapid development of new energy technologies, batteries, as the core energy storage components, the performance of their connection components plays a crucial role in the safety, stability, and reliability of battery systems. With the rapid development of fields such as electric vehicles and energy storage devices, the requirements for battery connectors are also increasing day by day, and traditional battery connectors are gradually revealing some problems that are difficult to meet modern needs.

[0003] During the connection process of traditional battery connectors, the positioning accuracy is often insufficient, and it is easy to have deviations in the docking of plugs and sockets, resulting in unreliable electrical connections and even potential safety hazards such as poor contact and overheating. For example, some simple plug-and-play connectors rely only on the rough positioning of the outer shell, and it is difficult to maintain a stable connection state under complex working conditions such as vibration and shock, and situations such as loosening and falling off may occur, affecting the normal operation of the battery system.

[0004] In terms of connection stability, traditional connectors mostly use simple snap or plug-and-play methods for fixation, and the connection strength is limited. For scenarios that need to withstand large mechanical stresses, such as the bumps during the driving of electric vehicles, this connection method is prone to failure, which will not only affect the normal power supply of the battery but may also cause serious safety accidents. At the same time, the conductive structure design of traditional connectors is not optimized enough, the contact area of the current bridge is relatively small, and the conductive performance needs to be improved. This will result in a large resistance during high-current transmission, causing energy loss and overheating problems, and reducing the efficiency and service life of the battery system.

[0005] In addition, the structural design of traditional battery connectors is relatively simple, with single functions and a lack of effective insulation and protection measures. During long-term use, it is easily affected by the external environment, such as the intrusion of dust and moisture, resulting in corrosion of internal conductors and a decrease in insulation performance, further affecting the reliability and safety of the connectors. Moreover, the installation and maintenance processes of traditional connectors are relatively cumbersome, requiring professional tools and personnel for operation, increasing the use cost and maintenance difficulty.

[0006] In summary, traditional battery connectors have many deficiencies in terms of positioning accuracy, connection stability, conductive performance, insulation protection, and installation and maintenance, and it is difficult to meet the requirements of high reliability, high safety, and high performance for battery connection components in the modern new energy field. Therefore, there is an urgent need to design a battery connector assembly to solve the above problems and improve the overall performance of the battery system. Summary of the Invention

[0024] As Figures 1 to 3As shown, in an exemplary embodiment of the present invention, the first positioning member 11 is composed of a first positioning cylinder 111, a first positioning wing 112, and a second positioning wing 113.

The first positioning wing 112 and the second positioning wing 113 are arranged on both sides of the first positioning cylinder 111 at 180° and are used to connect the housing of the plug 1.

[0025] As Figures 1 to 3 shown, in an exemplary embodiment of the present invention, the second positioning member 21 is composed of a second positioning cylinder 211, a first connecting wing 212, and a second connecting wing 213.

[0027] As Figures 1 to 3 shown, in an exemplary embodiment of the present invention, an insulating cap 61 is formed by injection molding at the nut end of the bolt 6. A circular stepped surface is formed at the edge of the insulating cap 61. A cylindrical installation cavity is formed in the plug 1. A flanging 12 is formed on the inner ring of the end of the installation cavity. The flanging 12 and the stepped surface are correspondingly arranged; elastic pieces 13 are formed on two opposite side walls of the installation cavity.

This structure is used to facilitate the assembly of the bolt 6 and the plug 1 and prevent the bolt 6 from shaking in the plug 1 and colliding with the housing to cause damage.

[0028] As Figures 1 to 3As shown, in an exemplary embodiment of the present invention, both the current bridge one 3 and the current bridge two 5 are configured as cylindrical structures and both have annular connection surfaces formed at the electrical connection ends. This structure increases the contact area, reduces the contact resistance, and improves the conduction efficiency. This design can effectively reduce the energy loss and heat generation problems during high-current transmission, improve the working efficiency and service life of the battery system. At the same time, the precise positioning and stable connection also ensure good contact between the current bridges, further optimizing the conduction performance.

[0029] As Figures 1 to 3 shown, in an exemplary embodiment of the present invention, on the peripheral wall of the base of the insertion end of the plug 1, there are multiple groups of positioning protrusions 14 arranged at equal angles, and at the end of the insertion end of the socket 2, there are multiple groups of positioning grooves 22 arranged at equal angles. The positioning protrusions 14 and the positioning grooves 22 are correspondingly and matchingly arranged.

[0030] As Figures 1 to 3 shown, in an exemplary embodiment of the present invention, on the outer periphery of the positioning protrusion 14, there is a first retaining groove 141, and on the outer periphery of the insertion end of the socket 2, there is a second retaining groove 23. The first retaining groove 141 and the second retaining groove 23 correspondingly and matchingly form an annular groove; further included is an annular buckle 8, and the annular buckle 8 is configured to be able to be buckled into the annular groove.

[0031] The novel battery connector assembly provided by the present invention has many significant beneficial effects, effectively solving many problems existing in traditional connectors, and significantly improving the reliability, stability, and safety of battery connection.

[0032] In terms of positioning accuracy, through the ingenious design of the first positioning member and the second positioning member, precise insertion positioning of the plug and the socket at a specific angle is achieved. The positioning cylinder one, positioning wings one and two of the first positioning member cooperate with the positioning cylinder two, positioning grooves one to four, etc. of the second positioning member to form a multiple positioning mechanism. This precise positioning design ensures that the current bridge one and the current bridge two can be accurately aligned, avoiding the problem of poor electrical connection caused by docking deviation, and ensuring the accuracy and stability of the connection even in a complex working condition environment.

[0033] The connection stability has been greatly improved. The setting of the bolt fastening assembly provides a strong mechanical fastening force for the plug and the socket. The bolt is screwed into the nut, making the two closely connected as a whole, and can withstand greater mechanical stress and vibration impact. At the same time, the cooperation of the positioning protrusions and grooves of the male end and the female end and the annular buckle further enhances the connection stability, effectively preventing the connector from loosening, falling off, etc. during use, and ensuring the reliable operation of the battery system under various working conditions.

[0034] In terms of electrical conductivity, both current bridge one and current bridge two adopt a cylindrical structure and form a ring-shaped connection surface at the electrical connection end, greatly increasing the contact area, reducing the contact resistance, and improving the electrical conductivity efficiency. This design can effectively reduce the energy loss and heat generation problems during large-current transmission, improving the working efficiency and service life of the battery system. At the same time, the precise positioning and stable connection also ensure good contact between the current bridges, further optimizing the electrical conductivity performance.

[0035] The insulation and protection performance are effectively guaranteed. The insulating cap formed by injection molding at the nut end of the bolt can not only prevent operators from accidentally contacting live parts, improving the safety of use, but also its cooperation with the flanging, elastic piece, and snap of the plug installation cavity ensures the stable installation of the insulating cap. In addition, the optimized design of the overall structure reduces the influence of the external environment on the internal conductor, improving the anti-corrosion and anti-interference capabilities of the connector.

[0036] In terms of installation and maintenance, the structure of this component is reasonably designed, and the positioning and fastening processes are easy to operate. Installation and disassembly can be completed without professional tools, reducing the use cost and maintenance difficulty. At the same time, the modular design of each component facilitates replacement and repair, improving the maintenance efficiency.

[0037] In summary, this new type of battery connector component comprehensively improves the battery connection performance through precise positioning, stable connection, optimized electrical conductivity structure, good insulation protection, and convenient installation and maintenance design. It has significant economic and social benefits and is applicable to battery connection scenarios in various new energy fields such as electric vehicles and energy storage devices.

[0038] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
