Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a pin header connector with added feet. Background Art

[0002] Pin header connectors are a common electronic component used for electrical connections between circuit boards. Traditional pin header connectors usually consist of a base and multiple pins, which are fixed through mounting holes on the base and can be docked with circuit boards or other external connectors. In order to ensure good electrical connection and mechanical stability, the design of pin header connectors needs to consider many factors, such as welding quality, anti-foolproofing design, shock absorption effect, etc.

[0003] Deficiencies of existing technology:

[0004] 1. Welding problem: When traditional pin header connectors are soldered to circuit boards, the base may directly contact the circuit board to form a tight fit, which is not conducive to the flow of solder between the pins and the circuit board, and may cause problems such as cold soldering or loose soldering.

[0005] 2. Limited vibration absorption capacity: Some existing pin header connectors are not equipped with special shock-absorbing devices. When subjected to external vibrations, the connection between the pins and the circuit board may become loose, affecting the stability and reliability of signal transmission.

[0006] 3. Lack of error-proofing design: Some pin header connectors lack effective error-proofing mechanisms (such as direction identification features), which can easily cause user errors, such as mistakenly inserting the connector into the reverse or mismatched position, thereby damaging the device.

[0007] Therefore, the existing technology has deficiencies and needs further improvement. Utility Model Content

[0008] In view of the problems existing in the prior art, the utility model provides a pin header connector with additional feet.

[0009] To achieve the above purpose, the specific solutions of the present utility model are as follows:

[0010] The utility model provides a pin header connector with additional feet, comprising:

[0014] The upper surface of the base is provided with a second foot between the two pins on the left and between the two pins on the right, and the second foot is provided along the width direction of the base;

[0015] The upper and lower ends of the pins extend out of the base, wherein the upper end of the pins is used to connect with the circuit board, and the lower end of the pins is used to connect with the external connector;

[0016] The first and second standing legs are arranged between the base and the external circuit board, so that a gap is formed between the base and the circuit board, which facilitates the flow of solder between the pins and the circuit board and avoids cold soldering.

[0017] Furthermore, the horizontal cross-section of the first foot is trapezoidal.

[0018] Furthermore, a shock-absorbing pad is provided on the lower side of the base, and the pin passes through the shock-absorbing pad;

[0019] The material of the shock-absorbing pad is silica gel.

[0020] Furthermore, an anti-fouling block is provided on the right side of the base.

[0021] Furthermore, the fool-proof block is in a convex shape.

[0022] Furthermore, a first chamfer is provided on the upper side of the mounting hole in the base.

[0029] 2. Enhanced structural support:

[0030] Adding feet to the front, back, and top surfaces of the base not only provides additional mechanical support, but also increases the rigidity of the entire connector, helping to maintain a good electrical connection and reducing the risk of deformation or damage due to external forces.

[0031] 3. Optimize shock absorption performance:

[0032] The underside of the base is equipped with a silicone shock-absorbing pad, which can effectively absorb external vibrations, reduce the impact of vibration on the connector, extend its service life and ensure the stability of signal transmission.

[0033] 4. Error-proofing design improvements:

[0034] There is a convex anti-mock block on the right side of the base to prevent users from making wrong directions during installation, ensuring the correct insertion method and reducing the potential risk of damage caused by misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Combine Figures 1-10 As shown, the utility model provides a pin header connector with an additional foot, comprising: a base 1 and a pin 2;

[0055] The base 1 is provided with two rows of parallel square mounting holes 101 extending vertically therethrough, and each mounting hole 101 is provided with a pin 2;

[0056] A first foot 102 is provided on the front and rear sides of the base 1 and on the side of each mounting hole 101;

[0057] The upper surface of the base 1 is provided with a second foot 103 between the two pins 2 on the left and between the two pins 2 on the right. The second foot 103 is provided along the width direction of the base 1.

[0058] The upper and lower ends of the pin 2 extend out of the outside of the base 1, wherein the upper end of the pin 2 is used to connect to the circuit board, and the lower end of the pin 2 is used to connect to the external connector;

[0059] The first and second legs 102, 103 are disposed between the base 1 and the external circuit board, creating a gap between the base 1 and the circuit board to facilitate solder flow between the pins 2 and the circuit board, thereby preventing cold solder joints. The horizontal cross-section of the first leg 102 is a trapezoid.

[0060] The base 1 is provided with a shock-absorbing pad 3 on the lower side, through which the pin 2 passes. The shock-absorbing pad 3 is made of silicone. The base 1 is provided with a fool-proof block 104 on the right side. The fool-proof block 104 is convex.

[0061] The mounting holes 101 in the base 1 are also provided with a first chamfer 105 on their upper sides. The upper and lower ends of the pins 2 are each provided with a second chamfer 201. The base 1 is made of an insulating material, and the pins 2 are made of a conductive material. There are ten mounting holes 101 and ten pins 2, respectively.

[0062] The principle of this utility model is as follows:

[0063] This utility model describes a pin header connector with additional footing, the main purpose of which is to improve welding quality, enhance mechanical stability and enhance shock absorption. The following is the specific working principle of the connector:

[0064] Configuration of base 1 and pin 2:

[0065] The base 1 is provided with two rows of square mounting holes 101 running through it from top to bottom, and a pin 2 is fixed in each mounting hole 101. This design ensures that the pin 2 can be firmly fixed in the base 1 and can be accurately positioned by the base 1.

[0066] The upper and lower ends of the pin 2 extend out of the base 1. The upper end is used for welding connection with the circuit board, and the lower end is used for docking with an external connector to realize the transmission of electrical signals.

[0067] The role of standing feet:

[0068] First and second support legs 102, 103 are located on the front, back, and top surfaces of the base 1. These support legs create a small gap between the base 1 and the external circuit board. This gap helps solder flow into the contact area between the pins 2 and the circuit board, improving soldering quality and reducing the likelihood of cold solder joints.

[0069] The horizontal cross-section of the first foot 102 is designed to be trapezoidal, which not only provides better support but also helps to evenly distribute pressure, further enhancing the reliability of the welding point.

[0070] Functions of shock-absorbing pad 3:

[0071] A shock-absorbing pad 3 made of silicone is installed on the underside of base 1, through which pins 2 pass. The silicone material has good elasticity and shock absorption properties, which can absorb and disperse external vibration or impact, protecting pins 2 from damage while maintaining a stable electrical connection.

[0072] Foolproof design:

[0073] A convex anti-fouling block 104 is provided on the right side of the base 1. This specific shape design prevents the user from mistakenly inserting the connector in reverse during installation, ensuring the correct installation direction and avoiding potential damage risks.

[0074] Chamfering:

[0075] Chamfers are provided on the upper side of the mounting hole 101 and on both ends of the pin 2. This treatment makes it easier to insert the pin 2 into the corresponding hole and more convenient to remove, while reducing wear on the pin 2 and the edge of the hole.

[0076] Material selection:

[0077] The base 1 is made of insulating material to prevent short circuits between different circuits, while the pins 2 are made of conductive material to ensure efficient electrical conduction. This combination ensures both safety and functional requirements.

[0078] Standardized design:

[0079] The present invention specifies a specific number of mounting holes 101 (10), thereby defining a standard specification, which is convenient for mass production and interchangeable use with other products of the same specification.

[0080] In summary, through the above-mentioned design features, this pin header connector with added feet can provide reliable electrical connection while also having excellent mechanical stability and vibration resistance, while also simplifying the user's installation process and reducing the risk of misoperation.
