Description

Technical Field

[0001] This utility model relates to the field of PIN connector technology, and in particular to a PIN connector with a small footprint. Background Technology

[0002] A PIN connector is a component used in electronic devices to achieve circuit connections, typically consisting of a pin and a header. PIN connectors play a crucial role in modern electronic devices, especially with the trend towards miniaturization and high performance, making their selection critical. Existing PIN connectors often feature flat terminals and wide solder leads, which can easily cause interference when installing plastic inserts. Utility Model Content

[0003] The purpose of this invention is to provide a PIN connector that occupies a small space, so as to at least solve the problems of the prior art mentioned above.

[0004] To achieve the above objectives, the present invention provides a space-saving PIN connector, including a base, a plastic core fixedly mounted on the upper end of the base, a terminal mounted on the surface of the plastic core, and a suction cap fixed on the upper surface of the terminal.

[0005] Alternatively, the terminal is formed by stamping.

[0006] Optionally, the terminals have an inward folding structure on both sides.

[0007] Optionally, the terminals are distributed in groups of four at equal intervals on the surface of the plastic core.

[0008] Optionally, the inner side of the suction cap is provided with a protrusion, and the suction cap is interlocked with the plastic core through the protrusion.

[0009] The space-saving PIN connector provided in this embodiment of the utility model has at least one of the following technical effects:

[0010] In this invention, by folding the terminals inward and narrowing them, the width of the solder feet is reduced during the assembly of the plastic core and terminals, saving PCB space and preventing loosening or detachment due to vibration or external force. This design effectively prevents the pins from popping out due to shaking during soldering, thereby improving the overall reliability of the product. The inward fold also increases its mechanical strength, making it more stable under equipment use and vibration. This design ensures that the pins maintain good contact performance during long-term use and reduces failures caused by mechanical stress. Attached Figure Description

[0019] 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 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

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.

[0021] 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.

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a technical solution: a space-saving PIN connector, including a base 1, with a plastic core 2 fixedly mounted on the upper end of the base 1. The main function of the core is to connect wires or cables to electronic devices, prevent short circuits between electrical devices, and ensure the accuracy and reliability of signal transmission. Terminals 3 are mounted on the surface of the plastic core 2. Terminals are important components in the connector used to achieve electrical connections, mainly responsible for the conductive transmission of electrical signals or current. A suction cap 4 is fixed on the upper surface of the terminal 3. The suction cap's main function is its automatic suction function. This function has significant advantages in improving user experience and device security. The automatic suction function of the PIN connector can achieve zero insertion force and automatic orientation, meaning that users do not need to manually align the connector for insertion and removal, thus greatly simplifying the operation process, especially suitable for hard-to-reach locations or occasions requiring frequent insertion and removal. This design not only improves ease of use but also reduces connection failures caused by improper manual operation.

[0025] Example 2

[0026] Please see Figure 1-4Terminal 3 is manufactured by stamping, and its two sides have an inward folding structure to prevent loosening or detachment due to vibration or external force. This design effectively prevents the pins from popping out due to shaking during the soldering process, thereby improving the overall reliability of the product. The inward folding also increases its mechanical strength, making it more stable when subjected to equipment use and vibration. This design ensures that the pins maintain good contact performance during long-term use and reduces failures caused by mechanical stress. Terminals 3 are evenly distributed in groups of four on the surface of the plastic core 2. The inside of the suction cover 4 is equipped with protrusions, and the suction cover 4 is interlocked with the plastic core 2 through the protrusions.

[0027] Working principle: When assembling the PIN connector, the terminal 3 first needs to be stamped, electroplated and cut. Then, the plastic core 2 is riveted to the terminal 3. Finally, the suction cap 4 is snapped together with the plastic core 2 by the protrusion, and the assembly of the PIN connector is completed.

[0028] 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.
