Description

Technical Field

[0001] This utility model relates to electrical connector technology, and in particular to a high-density battery connector suitable for miniaturized, highly integrated electronic devices. It can realize stable transmission of multiple signals and reliable power supply of high current, and is especially suitable for portable electronic devices with stringent requirements for space occupation, plugging and unplugging experience and connection reliability. Background Technology

[0002] As consumer electronics and IoT devices evolve towards miniaturization, thinness, and high integration, the number of signals that need to be transmitted simultaneously within these devices (such as status detection and data interaction signals) and the required stable power supply capabilities have increased significantly. This places higher demands on the number of pins, structural compactness, and electrical performance of battery connectors.

[0003] In existing technologies, most mainstream battery connectors adopt a configuration of "2 power pins + 4 signal pins" or "2 power pins + 6 signal pins," which can only meet basic power supply and limited signal transmission requirements, and cannot adapt to highly integrated devices that require multi-channel signal interaction. Furthermore, existing multi-pin battery connectors also have the following key drawbacks:

[0004] Excessive size: To accommodate more pins, traditional connectors need to increase their housing volume, which causes them to occupy valuable space inside electronic devices, contradicting the product design trend of "miniaturization and thinness".

[0005] Excessive insertion and extraction force: In multi-PIN configurations, the total insertion and extraction force of traditional rigid contact terminals (such as through-hole pin headers) increases significantly (usually exceeding 12N) after the single-PIN insertion and extraction force is superimposed. This not only makes it difficult for users to operate and results in a poor experience, but also easily damages the terminals or housing due to excessive force during the insertion and extraction process.

[0006] Alignment is difficult: The densely arranged pins lack an effective guiding structure, which can easily lead to "misaligned insertion" during insertion and removal, causing the terminals to bend and deform, directly disrupting the continuity of the electrical connection and reducing the lifespan of the connector;

[0007] Poor current distribution and heat dissipation: The power pin needs to carry the large current (usually 3-5A) required for the device to work. However, the power pin and signal pin of traditional connectors are mixed or poorly arranged, resulting in excessively long current paths, low cross-sectional area utilization, and increased resistance loss. During operation, local temperature rise is prone to be too high (exceeding 40K), which affects the stability of power supply and the reliability of connector.

[0008] Therefore, there is an urgent need for a battery connector that can achieve multi-PIN integration, low insertion and extraction force operation, precise alignment, and take into account both current carrying capacity and heat dissipation within a limited space, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of existing multi-PIN battery connectors, such as "large size, high insertion and extraction force, difficult alignment, and poor current heat dissipation", and to provide a multi-PIN battery connector that achieves the effects of "compact structure, smooth insertion and extraction, reliable connection, and strong current carrying capacity" by optimizing the terminal layout, innovating the contact structure, and adding a guide and foolproof design, thus meeting the needs of miniaturized and highly integrated electronic devices.

[0010] To achieve the above and other related objectives, the technical solution provided by this utility model is: a multi-PIN battery connector, comprising:

[0011] The male connector comprises a male insulating shell, two sets of male power terminals and multiple sets of male signal terminals. The multiple sets of male signal terminals are located in the central area of ​​the insertion end of the male insulating shell and arranged in an array. The two sets of male power terminals are located in the insertion end of the male insulating shell and are situated on two opposite sides of the central area.

[0012] The female connector comprises a female insulating shell, two sets of female power terminals and multiple sets of female signal terminals. The multiple sets of female signal terminals are located in the central area of ​​the insertion end of the female insulating shell and arranged in an array. The two sets of female power terminals are located in the insertion end of the female insulating shell and are situated on two opposite sides of the central area.

[0013] The male power terminal is matched with the female power terminal, and the male signal terminal is matched with the female signal terminal. Both the male power terminal and the male signal terminal adopt a plug-in terminal structure, and both the female power terminal and the female signal terminal adopt a double spring-loaded terminal structure.

[0014] A preferred technical solution is that the installation height of the male power terminal is higher than the installation height of the male signal terminal.

[0015] A preferred technical solution is that the end of the male power terminal is chamfered.

[0016] A preferred technical solution is as follows: the central area of ​​the plug-in end of the male insulating shell is provided with a guide post, and the central area of ​​the plug-in end of the female insulating shell is provided with a guide groove, and the guide post and the guide groove are correspondingly matched.

[0017] The preferred technical solution is as follows: the plug end of the male insulating shell is configured as a foolproof plug structure, and the plug end of the female insulating shell is configured as a foolproof socket structure, wherein the foolproof plug structure and the foolproof socket structure are correspondingly matched.

[0018] The preferred technical solution is that the outer periphery of the plug-in end of the male end insulating shell is provided with an annular groove, and a sealing ring is embedded in the annular groove.

[0019] The preferred technical solution is as follows: the insert-type terminal structure includes a blade-shaped terminal body, and the double-spring-type terminal structure includes a C-shaped terminal body. The two ends of the C-shaped terminal body are bent inward to form two sets of oppositely arranged springs for abutting against the two side walls of the blade-shaped terminal body.

[0020] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0021] High-density integration solves the "large size" problem: By optimizing the terminal layout (signal terminals in the center array and power terminals symmetrically arranged on both sides), multi-pin integration is achieved within a standard-sized housing, adapting to the space requirements of miniaturized electronic devices;

[0022] Low insertion and extraction force and high holding force solve the problem of "high insertion and extraction force": The female terminal adopts a double spring-type terminal structure, which reduces the total insertion and extraction force; at the same time, the deformation tension of the elastic bending part ensures a large contact normal force, and the holding force is stable after connection, preventing loosening under vibration.

[0023] Precise alignment prevents misinsertion and solves the "alignment difficulty" problem: the guide post and guide groove achieve initial positioning, the chamfered head of the male terminal guides insertion, the foolproof structure prevents misinsertion, and the triple protection avoids terminal misalignment and bending during insertion and removal, reducing the terminal damage rate;

[0024] High current carrying capacity and low temperature rise solve the problem of "poor current heat dissipation": The power terminals adopt a large cross-section blade-shaped structure and are arranged on both sides, with a short current path, which can stably carry 5A current and has a small temperature rise during operation, significantly improving power supply stability and connector life.

[0025] Reliable sealing and adaptability to complex environments: The silicone sealing ring on the outer periphery of the housing provides dust and water resistance, making it suitable for complex usage scenarios such as humidity and dust, thus expanding the application range of the connector.
