Description

Technical Field

[0001] The utility model relates to the technical field of female connectors, in particular to a double-layer positioning female connector. Background Art

[0002] In the field of connection between electronic equipment and circuit boards, the female header connector plays a vital role. It is a commonly used electronic connector to achieve electrical connection between board and board or line and board. The female header connector mainly consists of two parts: the socket (female header) and the corresponding pin. The advantage of this connector design is that it can provide stable and reliable multi-point connection, and it has the flexibility of disassembly and reuse, which greatly facilitates the maintenance and upgrade of electronic products.

[0003] In actual applications, in order to ensure the accuracy of electrical connection and efficient signal transmission, the pins and the headers are usually required to fit very precisely. The pins are usually thinner, and the corresponding sockets are smaller in size. This design helps to achieve a compact connection layout and improve space utilization efficiency. However, due to the fine size of the pins and sockets, as well as the high positioning requirements during manual or automatic plugging, it is very easy for the pin position to deviate during plugging. In particular, when the pins and sockets are not precisely aligned, the applied insertion force may cause the pins to slightly deviate or bend. Once the pins are bent, it will not only affect the stability of the connection and the integrity of the signal, but may also cause damage to the connecting components, further increasing the difficulty and cost of repair and replacement.

[0004] Therefore, those skilled in the art have proposed a double-layer positioning female connector. Utility Model Content

[0010] As a preferred embodiment, the guide connection mechanism further includes a clamping block, a wedge block and an inclined surface;

[0012] Through the above technical means, the clamping plate can be aligned through the inclined surface, and then the wedge block can be engaged with the clamping block, so as to achieve limiting.

[0013] As a preferred embodiment, the bottom of the sub-row is symmetrically fixedly connected with two upper fixing plates, and fixing screws are arranged inside the upper fixing plates. The top of the busbar is symmetrically fixedly connected with two lower fixing plates, and the fixing screws are threadedly connected with the lower fixing plates.

[0014] Through the above technical means, by turning the fixing screws, the fixing screws are connected to the lower fixing plate, thereby fixing the sub-row and the busbar.

[0015] As a preferred implementation, jacks are equidistantly provided inside the busbar, and pins are equidistantly fixedly connected to the bottom of the sub-bar, and the pins are used in conjunction with the jacks.
