Description

Technical Field

[0001] This utility model relates to the field of pin header and nut header connection technology, specifically a pin header and nut header anti-misalignment structure with positioning pins. Background Technology

[0002] As electronic devices develop towards miniaturization, integration, and high reliability, pin headers and sockets, as key electrical connection components, directly affect the performance and lifespan of the equipment through the accuracy and stability of their connections.

[0003] Traditional pin headers and sockets often employ two-point positioning or no positioning design, which has many drawbacks in practical use. On the one hand, during manual insertion and removal, misalignment of the pin header and socket is very likely to occur. This can lead to signal transmission interruption and poor contact, or even short circuit failure, burn out the circuit board, cause equipment downtime, or even safety accidents. On the other hand, in complex environments with high vibration and high impact, such as automotive, aerospace, and industrial automation, traditional connectors are prone to loosening and falling off due to insufficient positioning, which seriously affects system stability. To address this, we propose a pin header and socket anti-misalignment structure with positioning posts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pin header and nut header anti-misalignment structure with positioning posts, thus solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a pin header and nut header anti-misalignment structure with positioning posts, comprising a nut header, a pin header, a clamping component, and an elastic component. The pin header is provided on the top of the nut header, and the pin header is internally connected to the nut header. The pin header has two axially symmetrically distributed side boxes on its two opposite side walls. The clamping component and the elastic component are provided inside the side boxes. The clamping component and the elastic component are surface-fitted, and the clamping component is rotatably engaged with the side boxes.

[0006] Preferably, the female connector has positioning posts at all four corners, and the positioning posts are vertically positioned. The two opposite side walls of the female connector have two clamping grooves that are symmetrically distributed and are perpendicular to the positioning posts. The bottom of the female connector has a set of equidistant pins.

[0007] Preferably, each of the four corners of the pin header is provided with a positioning sleeve, and the positioning sleeve is slidably connected to the positioning post. The side wall of the pin header is provided with a mating groove corresponding to the bottom of the side box, and the mating groove corresponds to the clamping groove.

[0008] Preferably, the side box is a hollow rectangular box structure with an inner cavity inside, where a clamping component and an elastic component are placed. A rotating rod is provided at the bottom of the side box, and a pressing port is provided at the top of the side box.

[0009] Preferably, the clamping member has a curved folding plate structure, and a rotating hole is provided in the middle of the clamping member. The rotating hole is connected to the rotating rod in a rotatable fit. A clamping block is provided on the side of the clamping member corresponding to the bottom of the side box. The clamping block passes through the mating groove, and the shaft end of the clamping block is engaged with the clamping groove. A pressing plate is provided on the side of the clamping member corresponding to the top of the side box. The pressing plate is in an inclined state and extends out from the pressing port.

[0010] Preferably, the elastic element consists of three parts: a first mating plate, a second mating plate, and a group of five springs evenly distributed. The two shaft ends of the spring group are welded to the first and second mating plates respectively. The side of the first mating plate away from the spring is in contact with the clamping element, and the side of the second mating plate away from the spring is in contact with the inside of the side box.

[0011] Compared with the prior art, this utility model provides a pin header and nut header anti-misalignment structure with positioning pins, which has the following beneficial effects: 1. This pin header and nut anti-misalignment structure with positioning pins significantly improves anti-misalignment performance. Through the interference fit design of the positioning pins and positioning sleeves, the pin header and nut are forced to achieve precise axial and radial alignment at the initial insertion stage, completely solving the problem of misinsertion caused by human operation deviation in traditional structures. At the same time, the positioning pins are made of wear-resistant alloy material, which can maintain guiding accuracy even after long-term use. It is especially suitable for scenarios with strict requirements for connection stability, such as automotive and industrial control.

[0012] 2. This pin header and nut anti-misalignment structure with positioning pins has excellent vibration resistance and mechanical locking capabilities. The dynamic locking system composed of clamping and elastic components can effectively resist external impacts. The continuous elastic force provided by the spring keeps the clamping block and clamping groove at a constant clamping force. The wedge-shaped structure design of the clamping block will generate a self-tightening effect in the vibration environment, further suppressing the loosening tendency and significantly reducing maintenance costs. It is particularly suitable for extreme environment applications such as aerospace equipment. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 A pin header and nut header anti-misalignment structure with positioning post includes a nut header 1, a pin header 2, a clamping member 3, and an elastic member 4. The pin header 2 is provided on the top of the nut header 1. The pin header 2 is inserted into the nut header 1. The pin header 2 is provided on two opposite side walls of the outside of the pin header 2 and is provided with two side boxes 10 distributed symmetrically on both sides. The clamping member 3 and the elastic member 4 are provided inside the side boxes 10. The clamping member 3 and the elastic member 4 are in contact with each other and the clamping member 3 is rotatably engaged with the side box 10.

[0017] Furthermore, each of the four corners of the female connector 1 is provided with a positioning post 6, and the positioning post 6 is in a vertical position. The two opposite side walls of the female connector 1 are provided with two locking grooves 7 that are symmetrically distributed and perpendicular to the positioning post 6. The bottom of the female connector 1 is provided with a set of pins 8 that are evenly distributed. When the pin connector 2 is connected to the female connector 1, the positioning post 6 is inserted into the positioning sleeves 9 at the four corners of the pin connector 2 to play a precise positioning role, ensuring that the pins and the female connector are accurately aligned and preventing misinsertion. The locking groove 7 cooperates with the locking block 16 on the locking component 3 to achieve mechanical locking. The pins 8 are used to solder the female connector 1 to the circuit board to achieve electrical conduction. It is a basic connection component for signal and power transmission.

[0018] Furthermore, each of the four corners of the pin header 2 is provided with a positioning sleeve 9, and the positioning sleeve 9 is slidably connected to the positioning post 6. The side wall of the pin header 2 is provided with a mating groove 14 corresponding to the bottom of the side box 10. The mating groove 14 corresponds to the clamping groove 7. The positioning sleeve 9 and the positioning post 6 cooperate to guide the pin header 2 to be accurately fitted onto the pin header 1, ensuring that the pins of the pin header and the pin header are accurately connected and avoiding misalignment. The mating groove 14 provides an active channel for the clamping block 16 on the clamping member 3. When the clamping member 3 rotates, the clamping block 16 can pass through the mating groove 14 and engage with the clamping groove 7 of the pin header 1, so that the pin header 2 and the pin header 1 are firmly connected and prevented from falling off during use.

[0019] Furthermore, the side box 10 has an overall hollow rectangular box structure, and an inner cavity 11 is provided inside the side box 10. The clamping component 3 and the elastic component 4 are placed inside the inner cavity 11. The bottom of the side box 10 is provided with a rotating rod 12, and the top of the side box 10 is provided with a pressing port 13. The side box 10 provides installation space for the clamping component 3 and the elastic component 4. Its hollow rectangular box structure ensures a reasonable layout of internal components. The rotating rod 12 serves as the rotating shaft of the clamping component 3, allowing it to rotate flexibly. The pressing port 13 allows the operator to press the pressing plate 17 of the clamping component 3 to control the rotation of the clamping component 3, thereby realizing the clamping or loosening action, facilitating the insertion and removal of pin headers and nuts, and protecting the internal components from external interference.

[0020] Furthermore, the clamping member 3 has a curved and folded plate structure, and a rotating hole 15 is provided in the middle of the clamping member 3. The rotating hole 15 is rotatably connected to the rotating rod 12. A clamping block 16 is provided on the side of the clamping member 3 corresponding to the bottom of the side box 10. The clamping block 16 passes through the mating groove 14, and the shaft end of the clamping block 16 is engaged with the clamping groove 7. A pressing plate 17 is provided on the side of the clamping member 3 corresponding to the top of the side box 10. The pressing plate 17 is in an inclined state, and the pressing plate 17 is composed of... The pressing port 13 protrudes, and the clamping member 3 rotates around the rotating rod 12 through the rotating hole 15. After the pin header 2 and the pin header 1 are inserted into place, the operator presses the pressing plate 17 to make the clamping member 3 rotate. The clamping block 16 passes through the mating groove 14 and is inserted into the clamping groove 7 to firmly fix the pin header 2 and the pin header 1. The inclined pressing plate 17 is designed to facilitate the application of force, and when there is no external force, the elastic force of the elastic member 4 keeps the clamping member 3 in a clamped state to prevent the connection from loosening and ensure the reliability of the connection.

[0021] Furthermore, the elastic element 4 consists of three parts: a first mating plate 18, a second mating plate 19, and a set of five springs 20 evenly distributed. The two ends of the springs 20 are welded to the first mating plate 18 and the second mating plate 19 respectively. The side of the first mating plate 18 away from the springs 20 is attached to the clamping element 3, and the side of the second mating plate 19 away from the springs 20 is attached to the inside of the side box 10. The springs 20 provide elastic force, which is transmitted to the clamping element 3 through the first mating plate 18 and the second mating plate 19. This ensures that the clamping element 3 always maintains a clamping tendency when there is no external force, ensuring that the clamping block 16 is tightly engaged with the clamping groove 7. When it is necessary to separate the pin header and nut header, pressing the pressing plate 17 overcomes the spring force and causes the clamping element 3 to rotate, releasing the clamping. The elastic element 4 ensures that the clamping element 3 can repeatedly and reliably achieve clamping and releasing actions, enhancing the stability and durability of the connection structure.

High conductivity material is used to ensure low impedance transmission and enhance the structure's resistance to mechanical stress. Positioning sleeve 9: Positioning sleeve 9 is located at the four corners of the pin header 2. Its inner wall is precisely sliding with the positioning pin 6, providing dual axial and radial positioning with small error. Side box 10: The side box 10 is a hollow rectangular box structure with an inner cavity 11 to accommodate the clamping part 3 and the elastic part 4. A rotating rod 12 is provided at the bottom as a rotation fulcrum, and the pressing port 13 at the top exposes the pressing plate 17 for easy operation.

[0023] Working principle: Install the pin header and nut anti-misalignment structure with positioning posts correctly according to the diagram. This anti-misalignment structure achieves initial guiding positioning of the pin header 2 and nut 1 through the precise cooperation of the positioning posts 6 and positioning sleeves 9. Specifically, the positioning posts 6 at the four corners of the nut 1 are inserted into the positioning sleeves 9 of the pin header 2 first during insertion, forcibly limiting the relative position of the two, ensuring accurate subsequent alignment, and fundamentally avoiding the risk of misalignment. After insertion, the operator presses the pressing plate 17 protruding from the top of the side box 10, driving the clamping member 3 to rotate around the rotating rod 12, and the clamping block 16 at its end... The pin passes through the mating groove 14 of the pin header 2 and is embedded in the locking groove 7 of the pin header 1, forming a mechanical interlock. At this time, the elastic element 4 pushes the mating plate 18 against the locking element 3 through the elastic force of the spring 20, so that the locking block 16 continuously presses against the inner wall of the locking groove 7, which can prevent loosening even in a high vibration environment. When separation is required, press the pressing plate 17 again to overcome the elastic force of the spring 20, so that the locking block 16 can be released from the locking groove 7 to unlock. The synergistic effect of the positioning pin 6 and the locking element 3 not only ensures accurate guidance during insertion, but also achieves high reliability of connection through the dual mechanism of rigid positioning and elastic locking.
