Description

Technical Field

[0001] This utility model belongs to the field of pin header technology, and particularly relates to pin header female terminal. Background Technology

[0002] Pin header female terminals are essential components for electrical connections between circuit boards in electronic devices, typically consisting of an insulating base and metal pins. The base is usually made of high-strength plastic materials such as PBT or nylon, while the metal pins are made of copper alloy or phosphor bronze, and are tin- or gold-plated to enhance conductivity and oxidation resistance. Pin header female terminals, used in conjunction with pin header connectors, achieve stable electrical connections and are suitable for automated assembly. However, existing pin header female terminal contact spring designs only have two springs, which can easily lead to misalignment on the other horizontal plane after mating with the male connector, and the contact resistance is not effectively reduced.

[0023] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figure 1-5 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figure 1-5As shown, a pin header female connector is provided, including a male connector 1. The lower end of the male connector 1 is connected to an extension 2. Near the upper end of the extension 2, square pins 3 are connected. These square pins 3 are primarily used to achieve electrical connections between circuit boards. These pins are made of metal and are typically plated with tin or gold to enhance conductivity and prevent oxidation. They are responsible for transmitting electrical signals and current and are the core components of the pin header female connector. In electronic devices, the pin header female connector, in conjunction with a corresponding pin header connector, achieves stable electrical connections between circuit boards, ensuring the transmission of signals and current. The back of the extension 2 is connected to solder pads 6, which mainly act as bridges, connecting different circuit sections on the circuit board to achieve the transmission of current or signals. The design of the solder pads 6 needs to consider the characteristics of the circuit board, including pin spacing, size, and lead length, to ensure the development requirements of high-density, high-speed transmission, and high-frequency directions. In addition, the solder foot 6 also has the functions of positioning, fixing and increasing the strength of the component, which helps to strengthen the connection between the connector and the PCB and avoid damage to the soldering between the terminal and the PCB due to excessive terminal stress. The upper side of the inner wall near the tail end of the extension 2 is fixed with a top spring 7 and the two sides of the inner wall near the tail end are fixed with side springs 8. The design of the three springs can effectively reduce the contact resistance of the product. The protrusion 9 is provided in the extension 2 near the protrusion 5. The protrusion 9 can effectively prevent the male and female connectors from misaligning after insertion. There are two sets of side springs 8, which are symmetrically arranged on the inner wall of the extension 2. The protrusion 9 is arc-shaped.

[0028] At least one embodiment of the present invention can achieve the following: the outer surface of the extension 2 is provided with a groove 4, and the inner wall of the groove 4 is integrally formed with a protrusion 5. The protrusion 5 is for the purpose of achieving precise fit and fixation between components, ensuring the stability and reliability of the connection, and preventing loosening or separation due to external force or other factors. The male head 1, the extension 2 and the square pin 3 are integrally stamped and formed, and the extension 2 has a bent design.

[0029] By integrally molding the male connector 1 and the square pin 3, a tighter and more stable contact between the pin and the female connector terminal is ensured. This design reduces signal transmission problems caused by poor contact, thereby improving the operational reliability of electronic equipment. The integral molding process reduces manufacturing errors, ensuring that the shape and size of each pin are consistent, thus improving the overall quality and performance of the connector. The integral molding design reduces the number of assembly steps for multiple components, simplifies the production process, lowers production costs, and helps improve production efficiency. Due to the flexibility of the integrally molded male connector and square pin design, it can be adjusted and replaced according to different application requirements, thereby improving the versatility and adaptability of the equipment. The integral molding technology solves the problems of easy bending and skewing and molding chips of square pins during the molding process, ensuring the integrity and quality of the pins.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
