Description

Technical Field

[0001] This utility model relates to the field of pin header connector technology, specifically to an anti-detachment pin header connector. Background Technology

[0002] Although existing anti-loosening pin header connectors have been continuously innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN222320675U discloses a pin header and female header connector, which relates to the field of connector technology. To solve the problem that in the prior art, when the pin header and female header are plugged in and out, there is no other auxiliary clamping structure, which makes them prone to separation under force during use, resulting in a circuit break, the pin header has pins symmetrically arranged on both sides, and there are multiple pins. The female header has a slot on one side, and there are multiple slots arranged in two rows with intervals. The front end of the female header has a spring groove. The inside of the female header has a rod cavity along one side of the spring groove. The inside of the female header has a translation cavity symmetrically arranged above and below the rod cavity, and there are multiple translation cavities. The inside of the spring groove has a pressure plate.

[0004] The aforementioned connector uses a straight rod to drive several pressure plates to achieve auxiliary positioning of the pins. However, its overall structure is too complex, and the number of pins is generally large when the pins are arranged. Installing a positioning component for each pin would undoubtedly increase production costs significantly. At the same time, it is also difficult to install a large number of parts into the pin header, resulting in low actual production efficiency. Therefore, an anti-dislodgement pin header connector is needed to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an anti-dislodgement pin header connector to solve the problems mentioned in the background art. The connector uses a straight rod to drive several pressure plates to achieve auxiliary positioning of the pins. However, its overall structure is too complex, and the number of pins is generally large when pin header is installed. If a positioning component is installed for each pin, it will undoubtedly increase the production cost significantly. At the same time, it is also difficult to install a large number of parts into the pin header, resulting in low actual production efficiency.

[0006] This utility model provides the following technical solution: an anti-detachment pin header connector, including a connection mechanism, wherein the connection mechanism includes a pin header with insert pins and a female header with connecting rods; It also includes an anti-loosening mechanism, which includes a screw seat divided into two parts along the X-axis or Y-axis; The two parts of the screw seat are respectively connected to the pin header and the nut header. After the pin header and the nut header are inserted, the screw seat parts are aligned and attached to each other. Additionally, after the two parts of the screw seat are aligned, a nut is screwed into the surface to form a positioning.

[0007] To achieve the above technical solution, the screw seat is divided into two parts, which together form the guide diameter for the nut to screw into. This allows the nut to lock onto the two screw seat parts. Compared with the prior art, this device, through the screw seat that is locked by the nut and cannot be separated, ensures that the pin header and nut header will not accidentally come loose after insertion, thus improving the stability of the connection.

[0008] As a further improvement to this utility model, the number of screw seats is only one.

[0009] To achieve the above technical solution, the insertion orientation of the pin header and nut header is limited, thus avoiding incorrect insertion direction.

[0010] As a further improvement to this utility model, the two parts of the screw seat are respectively integrated with the pin header and the nut header as an integral component.

[0011] Implementing the above technical solution facilitates the production of pin headers and nut headers with a portion of the screw seat.

[0012] As a further improvement to this utility model, the screw seat has a frustoconical design at the screw-in port.

[0013] The above technical solution facilitates the screwing of the nut into the screw seat.

[0014] As a further improvement to this utility model, the screw seat is composed of a support area and a screw area. Anti-slip texture is provided on the surface of the support area, and the nut is screwed to be in contact with the support area of ​​the screw seat.

[0015] The above technical solution improves the anti-slip effect in the area between the nut and the screw seat support, making the nut less prone to loosening.

[0016] As a further improvement to this utility model, the two mating surfaces of the screw seat are respectively provided with protrusions and concave holes.

[0017] The above technical solution improves the stability of the screw seat after the two parts are in contact.

[0018] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a screw seat divided into two parts, which together form a guide for the nut to be screwed in, thereby allowing the nut to be locked onto the two screw seat parts.

[0019] 2. Compared with the prior art, this utility model has a screw seat that is locked by a nut and cannot be separated, which ensures that the pin header and nut will not come loose accidentally after insertion, thus improving the stability of the connection. Attached Figure Description

Nut; Detailed Implementation The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example: Referring to the accompanying drawings, this utility model provides an anti-loosening pin header connector. Through a mechanical locking structure between the screw base 210 and the nut 211, the anti-loosening connection between the pin header 110 and the nut 111 is achieved. Its core structure and usage process are as follows: In the connecting mechanism 100 The 110 pin header insulating base is made of PA66 + 30% glass fiber injection molding. Multiple sets of pins are fixed on the base. The pin spacing is adapted to the female connector. The number of pins can be set according to requirements (commonly 8 to 20 pins). The female header 111 and the male header 110 are plugged in and out. The material and size of the insulating base are matched with the male header 110. An internal connecting rod is provided, and the connecting rod corresponds one-to-one with the pin of the male header 110 to ensure stable electrical connection.

[0027] In the anti-loosening mechanism 200 The screw seat 210 is divided into two parts along the axial direction (X-axis and Y-axis), which are injection molded into the insulating base of the pin header 110 and the nut header 111 respectively (the material is the same as the base to enhance the structural strength). There is one of them (located on one edge of the connector, which does not affect the pin / connector layout). The screw seat 210 consists of a support area and a screw area. The surface of the support area has anti-slip texture to increase friction with the nut 211. At the same time, the two contact surfaces of the screw seat 210 are respectively provided with protrusions and concave holes. After insertion, the protrusions are embedded into the concave holes to achieve circumferential positioning. The screw seat 210 has a frustoconical shape at the screw-in port to guide the nut 211 to be quickly aligned and screwed in. Nut 211 is a standard hexagonal nut that is threaded into the screw area of ​​screw seat 210. When tightened, the rear end face fits tightly into the support area of ​​screw seat 210 (the axial clamping force achieves anti-loosening locking between pin 110 and nut 111).

[0028] The specific usage process is as follows: Plug-in alignment Manually align the pin header 110 and the nut header 111 to ensure that the protrusions and concave holes of the two parts of the screw seat 210 are aligned; Insert the pin of pin header 110 vertically into the connecting rod of pin header 111 until the pin is fully in place. At this time, the two parts of screw seat 210 are tightly attached (the protrusion is fully embedded in the concave hole).

[0029] Anti-loosening fixation Hold nut 211 and screw it into the screw area along the frustoconical end of screw seat 210 until nut 211 is screwed into the support area along the screw area of ​​screw seat 210 (anti-slip texture prevents slippage), so that the end face of nut 211 is completely in contact with the support area of ​​screw seat 210 (without gaps), thus completing the anti-loosening fixation.

[0030] Disassembly and separation Rotate nut 211 in the opposite direction to completely unscrew it from screw seat 210; Pull out the pin 110 along the axial direction to separate the pin from the connecting rod of the nut 111, and the protrusions and concave holes of the two parts of the screw seat 210 disengage simultaneously.
