Description

Technical Field

[0001] This utility model relates to connector technology, and in particular to a battery connector. Background Technology

[0002] As electronic products rapidly evolve towards miniaturization and high density, the size constraints of their internal components are becoming increasingly stringent. Battery connectors, as a crucial interface for power supply and signal transmission in electronic products, face significant technical challenges as their design must simultaneously meet the dual requirements of "small size" and "high performance."

[0003] Existing battery connectors have the following prominent problems in practical applications:

[0004] The contradiction between current carrying capacity and size is prominent: the outer diameter of current micro battery connectors is mostly controlled at around 7mm to adapt to narrow spaces, but the cross-sectional area design of traditional power terminals is limited, resulting in increased resistance and excessive temperature rise. It is difficult to stably carry currents of more than 3A under this size, and it cannot meet the needs of high-performance micro devices for large current transmission of 5A and above, which seriously restricts the performance of the devices.

[0005] Insufficient anti-misinsertion design: Most small connectors adopt symmetrical or near-symmetrical mating structures, which can easily lead to reverse or incorrect insertion by users in dim environments or fast-paced operation scenarios, potentially causing safety risks such as device burnout or battery short circuit; some connectors with foolproof keys have unreasonable foolproof structure designs, which occupy extra space or increase structural complexity, thus violating the miniaturization requirements.

[0006] Poor connection reliability: The simple plug-in structure lacks an effective locking mechanism. When the equipment is subjected to vibration, impact or accidental pulling, the connector is prone to loosening, resulting in power interruption or abnormal signal transmission, which affects the normal operation of the equipment.

[0007] In view of the shortcomings of the existing technology, there is an urgent need to design a battery connector with small outer diameter, strong current transmission capability, good anti-misinsertion effect and reliable connection, so as to meet the development needs of microelectronic products. Utility Model Content

[0008] The purpose of this utility model is to overcome the defects of the prior art and provide a battery connector with a maximum outer diameter of only 7mm, which realizes the functions of "stable transmission of 5A high current under small size", "efficient prevention of mis-insertion" and "convenient and reliable connection", while integrating multiple signal transmission channels to meet the high performance requirements of micro electronic products.

[0009] To achieve the above and other related objectives, the technical solution provided by this utility model is: a battery connector, comprising:

[0010] A male connector includes a male insulating shell, a male power terminal, and a male signal terminal. The insertion end of the male insulating shell is configured as a plug structure. The end of the plug structure is provided with region one and region two. Region two extends inward to form a slot that is not centrally symmetrically arranged. The male power terminal is embedded in the plug structure corresponding to region one, and the male signal terminal is fixed in the slot corresponding to region two.

[0011] A female connector includes a female insulating shell, a female power terminal, and a female signal terminal. The insertion end of the female insulating shell is configured as a socket structure. The end of the socket structure is provided with region three and region four. Region four extends outward to form a non-centrally symmetrically arranged plug. The female power terminal is fixed in the socket structure corresponding to region three, and the female signal terminal is embedded in the plug corresponding to region four.

[0012] The plug structure is connected to the socket structure and then fixed by a snap-fit ​​connection, and the slot and the plug are matched and matched accordingly.

[0013] The preferred technical solution is as follows: the outer periphery of the plug structure is provided with two oppositely arranged buckles, and the outer periphery of the socket structure is provided with two oppositely arranged buckle holes, the buckles and the buckle holes being matched and matched accordingly.

[0014] The preferred technical solution is that a guide groove is provided on the inner wall of the frame opening of the socket structure, and the guide groove is arranged along the insertion direction and communicates with the buckle hole.

[0015] A preferred technical solution is that it further includes a sealing ring, which is embedded in the bottom of the socket structure and corresponding to the end of the plug mechanism.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0017] Highly efficient anti-misinsertion: The matching structure of the male end's non-centrally symmetrical slot and the female end's non-centrally symmetrical pin allows only one correct angle of insertion, completely avoiding the risk of reverse insertion and misinsertion, and improving the safety of equipment use;

[0018] Reliable and convenient connection: The locking structure of the buckle and buckle hole, together with the guide groove, simplifies the insertion and removal operation (providing clear engagement feedback) and effectively resists the risk of loosening caused by vibration and pulling; at the same time, the bottom sealing ring design further improves the sealing performance and environmental adaptability of the connection.

[0019] High integration: Multiple power supply terminals and multiple signal terminals are integrated within a small outer diameter space, which can take into account both high current power supply and multi-channel signal transmission, and meet the multi-functional needs of micro electronic products.

[0026] like Figures 1 to 2 As shown, according to a general technical concept of the present invention, a battery connector is provided, comprising:

[0027] The male connector includes a male insulating housing 1, a male power terminal 2, and a male signal terminal 3. The insertion end of the male insulating housing 1 is configured as a plug structure 11. The end of the plug structure 11 is provided with a first region 111 and a second region 112. The second region 112 extends inward to form a slot that is not centrally symmetrically arranged. The male power terminal 2 is embedded in the plug structure 11 corresponding to the first region 111, and the male signal terminal 3 is fixed in the slot corresponding to the second region 112.

[0028] The female connector includes a female insulating shell 4, a female power terminal 5, and a female signal terminal 6. The insertion end of the female insulating shell 4 is configured as a socket structure 41. The end of the socket structure 41 is provided with a third region 411 and a fourth region 412. The fourth region 412 extends outward to form a non-centrally symmetrically arranged plug. The female power terminal 5 is fixed in the socket structure 41 corresponding to the third region 411, and the female signal terminal 6 is embedded in the plug corresponding to the fourth region 412.

[0029] The plug and socket structures are connected and fixed by a snap-fit ​​mechanism, and the slot and plug are matched accordingly.

[0030] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the outer periphery of the plug structure 11 is provided with two oppositely arranged buckles 113, and the outer periphery of the socket structure 41 is provided with two oppositely arranged buckle holes 413, with the buckles 113 and buckle holes 413 correspondingly matched.

[0033] In addition, both the male end insulating shell 1 and the female end insulating shell 4 are injection molded from high temperature resistant PA66 plastic material, which combines lightweight and structural strength and is suitable for the internal temperature environment of electronic products.

[0034] Male power terminal 2, male signal terminal 3, female power terminal 5, and female signal terminal 6 are all made of phosphor bronze and have been tin-plated.
