Description

Technical Field

[0001] This utility model relates to the field of pin header connector technology, and in particular to an adjustable pin header connector with multiple pitch compatibility. Background Technology

[0002] A pin header connector is an electronic connector consisting of multiple metal pins arranged at fixed intervals and fixed to an insulating base. It is primarily used for electrical connections between circuit boards or for connections between circuit boards and cables, and is one of the most fundamental interconnect components in electronic equipment.

[0003] Traditional pin header connectors typically use a fixed-pitch design, where the position and spacing of the metal pins are fixed during manufacturing and cannot be adjusted during use, making them unsuitable for PCBs or connectors with different pitches. Utility Model Content

[0004] To address the problems mentioned above, this invention provides an adjustable pin header connector with multiple pitch compatibility, allowing users to adjust the spacing between metal pins as needed to adapt to PCBs or connectors with various pitches.

[0005] The solution adopted by this utility model to solve its technical problem is: a multi-pitch compatible adjustable pin header connector, including an insulating base and metal pins. A slide rod is fixedly connected inside the insulating base. The insulating base is provided with a limiting groove. The metal pin is slidably disposed on the slide rod and slides inside the limiting groove. The slide rod is provided with a hook. The bottom of the metal pin is provided with a locking interface. The locking interface and the hook engage with each other. A switch is provided on the side of the slide rod to control the retraction and extension of the hook inside the slide rod.

[0006] Furthermore, the switch includes a spring-loaded part located inside the slide rod and fixedly connected to the hook. The other end of the spring-loaded part is fixedly connected to a rotating shaft, which extends to the outside of the slide rod and the insulating base. The rotating shaft is an insulator. The bottom of the hook is provided with an abutting part, which abuts against the bottom surface of the card interface to prevent the spring-loaded part from popping out of the card interface.

[0007] Furthermore, a hand grip is provided on the surface of the insulating base extending from the rotating shaft.

[0008] Furthermore, the insulating base has a positioning hole on its side, and an abutment rod is inserted into the positioning hole. The abutment rod is used to abut against both sides of the grip.

[0009] Furthermore, the side of the limiting groove is provided with a scale.

[0010] Furthermore, the slide bar is embedded with several magnetic rings, which correspond to the scale lines. A soft magnetic alloy sheet is fixedly connected to the bottom of the metal needle, and the soft magnetic alloy sheet has the opposite magnetic properties to the magnetic rings.

[0011] Furthermore, the hook has an arc edge.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] (1) The metal pin is slidably connected to the slide bar. The limiting groove is used to ensure the straightness of the sliding trajectory of the metal pin. Through the above design, it is convenient for users to adjust the spacing between the metal pins, so that the pin header connector can be adapted to PCB boards or connectors with various spacings.

[0014] (2) The slide bar is designed with a hook and a locking interface is provided at the bottom of the metal needle. The hook can be locked into the locking interface. Through the above design, the mechanical locking function of the metal needle can be realized to ensure that the metal needle does not move after positioning. At the same time, the hook of this application is designed with an arc edge, which can reduce the frictional resistance when the hook is engaged and extend its service life.

[0015] (3) The attraction between the opposite poles of the soft magnetic alloy sheet and the magnetic ring facilitates the alignment of the metal needle with the scale line.

[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4 As shown, an adjustable pin header connector with multiple pitch compatibility includes an insulating base 1 and metal pins 4. The insulating base 1 is fixedly connected to a slide rod 2 by an interference fit. The insulating base 1 is provided with a limiting groove 3. The metal pins 4 are slidably disposed on the slide rod 2 and slide inside the limiting groove 3. The slide rod 2 is provided with a hook 51. The bottom of the metal pin 4 is provided with a locking interface. The locking interface and the hook 51 are locked together. A switch is provided on the side of the slide rod 2 to control the retraction and extension of the hook 51 inside the slide rod 2.

[0026] Specifically, such as Figure 1 and 2 As shown, the metal needle 4 in this embodiment is L-shaped and has a slip ring at the bottom. It is fitted onto the outside of the slide rod 2 via the slip ring. Limiting grooves 3 are provided on both the top and side surfaces of the insulating base 1. The metal needle 4 is made of L-shaped phosphor bronze and is gold-plated. Its vertical section is the main signal transmission component. It should be noted that the slip ring, hook 51, and slide rod 2 in this embodiment are all insulators. To ensure the insulation properties and rigidity of the slide rod 2, it is made of glass fiber reinforced nylon in this embodiment.

[0027] like Figure 3 As shown, the switch includes a spring-loaded part 52 located inside the slide rod 2 and fixedly connected to the hook 51. A rotating shaft 53 is fixedly connected to the other end of the spring-loaded part 52, extending to the outside of the slide rod 2 and the insulating base 1. The rotating shaft 53 is an insulator. The bottom of the hook 51 has an abutment part 54 that abuts against the bottom surface of the card interface to prevent the spring-loaded part 52 from popping out of the card interface. A hand grip part 55 extends from the surface of the insulating base 1 onto the rotating shaft 53.

[0028] like Figure 2As shown, the insulating base 1 has a positioning hole 6 on its side, and a connector 7 is inserted into the positioning hole 6. The connector 7 is used to abut against both sides of the grip part 55. In this embodiment, the connector 7 is a connector block. When the user rotates the pivot 53 to retract the hook 51 into the slide bar 2, the connector block is inserted into the positioning hole 6 to fix the state of the hook 51, thereby facilitating the user to adjust the position of the metal pin 4 to adapt it to various circuit boards. When the user removes the connector block, the hook 51 pops out, fixing the position of the metal pin 4.

[0029] In this embodiment, the limiting groove 3 has a scale 8 on its side. Specifically, to make the pin header connector applicable to more circuit boards, the scale 8 is marked with internationally recognized spacing standards, and 0.5mm subdivision scales 8 are added between the standard scales 8. In another embodiment, to enhance tactile identification, raised dots are provided at the standard spacing positions of the insulating base in this embodiment.

[0030] In another embodiment, a plurality of magnetic rings are embedded inside the slide rod 2, and the magnetic rings correspond to the scale line 8 of the standard spacing. A soft magnetic alloy sheet is fixedly connected to the bottom of the metal needle 4. In this embodiment, the magnetic rings are radially magnetized, and the direction of the magnetic poles on their outer surface is opposite to the direction of the induction magnetic poles of the soft magnetic alloy sheet. When the metal needle 4 slides to the position corresponding to the magnetic ring, it can generate a positioning attraction force of 0.8-1.5N, thereby helping the metal needle 4 to be positioned on the scale line 8 of the standard spacing.

[0031] like Figure 4 As shown, in this embodiment, the hook 51 is designed with an arc edge. The body of the hook 51 is made of wear-resistant PPS material, and the radius of curvature of its arc edge is R0.5mm. The above design can significantly reduce the wear on the hook 51.

[0032] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
