Description

Technical Field

[0001] The utility model relates to the technical field of circuit board accessories, and particularly relates to a circuit board connector. Background Art

[0002] In the field of electronic technology, we often stack two printed circuit boards for installation. This installation method has two major advantages: one is that it can save space, and the other is that it has good replaceability. The stacked installation between the upper and lower layer PCB boards is usually completed through a connector. A common connection method of existing printed circuit board connectors is to use pin headers in cooperation with female headers to achieve electrical connection. For example, a printed circuit board connector disclosed in a Chinese patent with the authorized publication number of CN102347544B includes pin headers fixed on the first PCB board and female headers fixed on the second PCB board. The pin headers are arranged in two parallel rows, and a pair of opposite pin headers in the first row and the second row are electrically connected; there are connection holes on the female header, and the positions of the connection holes correspond to the pin headers one by one, and a pair of opposite connection holes in the first row and the second row are electrically connected; an "L"-shaped conductive spring piece is placed on the female header, and the other end is bent and extends into the connection hole after bending. The printed circuit board connector with this structure uses paired pin headers in cooperation with female headers to transmit the same signal, ensuring the reliability of signal transmission of this pair of pin headers, and thus having high conductive reliability. However, the positions of the pin headers of the above circuit board connector are fixed and cannot be adjusted according to actual needs, so its adaptability is poor. Content of the Utility Model

[0003] The purpose of the utility model is to provide a circuit board connector aiming at the above deficiencies, which can adjust the connection position of the pin headers according to actual needs and has better adaptability.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A circuit board connector includes a pin header seat and a female header seat, a pin header sliding groove arranged on the pin header seat, a metal plate arranged in the pin header sliding groove, a plurality of pin seat sliders slidably connected in the pin header sliding groove, a pin header driving component used to drive the plurality of pin seat sliders to approach or move away from each other, a pin header slot arranged on the pin seat slider, a plurality of female header slots arranged equidistantly on the female header seat, a first metal elastic piece arranged in the female header slot, and an inserted pin header used to insert the pin header slot and the female header slot. One end of the pin header slot communicates with the metal plate, and when the inserted pin header is inserted into the pin header slot, the end of the inserted pin header abuts against the metal plate.

[0006] Further, the pin header driving component includes a lead screw rotatably connected to both ends of the pin header sliding groove, a hand wheel arranged at one end of the lead screw, and an internal thread hole is arranged on the pin seat slider opposite to the lead screw.

[0007] Further, the pin header is in a C shape, and a first transverse portion and a second transverse portion are arranged on the pin header. The first transverse portion and the second transverse portion are respectively inserted into the pin socket and the female socket.

[0008] Further, arc-shaped plugs are respectively arranged at the ends of the first transverse portion and the second transverse portion.

[0009] Further, a concave is radially arranged on the first transverse portion, and a plurality of second metal elastic pieces are arranged in the pin socket opposite to the concave.

[0010] Further, the number of the female sockets is at least twice the number of the pin sockets.

[0011] The beneficial effects of the utility model are as follows:

[0012] In practical applications, when in use, the pin base and the female base are respectively connected to two circuit boards. The pin base slider is driven by the pin driving component to slide along the pin chute, so as to adjust the distance between adjacent pin base sliders, and thus adjust the positions between adjacent pin headers. The pin headers are inserted into the pin sockets and the female sockets, so that the metal plate on the pin base is communicated with the female base. The utility model can adjust the connection positions of the pins according to actual requirements, and has better adaptability. Description of the Drawings

[0017] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, a circuit board connector includes a pin header base 1 and a female header base 2, a pin header chute 11 provided on the pin header base 1, a metal plate 3 provided in the pin header chute 11, a plurality of pin base sliders 4 slidably connected in the pin header chute 11, a pin header drive assembly 5 for driving the plurality of pin base sliders 4 to approach or move away from each other, a pin header slot 41 provided on the pin base slider 4, a plurality of female header slots 21 equidistantly provided on the female header base 2, a first metal spring piece 22 provided in the female header slot 21, a pin header 6 for plugging the pin header slot 41 and the female header slot 21. One end of the pin header slot 41 communicates with the metal plate 3. When the pin header 6 is inserted into the pin header slot 41, the end of the pin header 6 abuts against the metal plate 3.

[0018] During use, the pin header base 1 and the female header base 2 are respectively connected to two circuit boards. The pin base sliders 4 are driven by the pin header drive assembly 5 to slide along the pin header chute 11, and the distance between adjacent pin base sliders 4 is adjusted, so as to adjust the positions of adjacent pin headers 6. The pin header 6 is used to plug the pin header slot 41 and the female header slot 21, so that the metal plate 3 on the pin header base 1 is connected to the female header base 2. The utility model can adjust the connection position of the pin header according to actual needs, and has better adaptability.

[0019] As Figure 1 、 Figure 2 and Figure 3 shown, the pin header drive assembly 5 includes a lead screw 51 rotatably connected to both ends of the pin header chute 11, a handwheel 52 provided at one end of the lead screw 51, and an internal thread hole is provided on the pin base slider 4 opposite to the lead screw 51. In this embodiment, by rotating the handwheel 52, the handwheel 52 is screwed to the pin base slider 4 through the lead screw 51, driving the pin base slider 4 to slide along the pin header chute 11, so that adjacent pin base sliders 4 and pin headers 6 approach or move away from each other, and the connection position of the pin header 6 is adjusted.

A plurality of second metal elastic pieces 42 are arranged in the pin socket 41 opposite to the inner concave portion 62. In this embodiment, after the first transverse portion is inserted into the pin socket 41, the second metal elastic pieces 42 are pressed into the inner concave portion 62, effectively preventing the first transverse portion from loosening.
