Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a board end connector structure. Background Art

[0002] Connectors are also called connectors. They are also called joints and sockets in China. They generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals.

[0003] In some display fields or some communication fields, we often encounter connection methods that require signal data as the main method and current transmission as the auxiliary method. In order to achieve the simultaneous transmission of current and signal, two connectors are generally used to achieve mutual non-interference. However, this method also has some limitations. That is, when the device is small in size and has a large number of signal pins, the production cost of using two connectors is high. Therefore, a connector that integrates multi-PIN data connection and current transmission is designed according to customer needs. Utility Model Content

[0007] The female connector includes a second insulator, the second insulator is provided with an insertion groove that matches the tongue portion, the upper wall and the lower wall of the insertion groove are provided with a second signal PIN needle that matches the first signal PIN needle, and the two sides of the second insulator are provided with power pins that match the power slot portion.

[0008] In the actual design of the technical solution of the utility model, the first signal PIN needle is formed on the tongue portion, and the first signal PIN needle is bent downward and connected to the PCB board, wherein the tongue portion and the power slot portion are assembled on the first insulator as separate modules, thereby facilitating the assembly of the female plug; wherein the structure of the female plug is similar to that of the male plug, and the insertion slot portion and the power plug pin are also separately formed and then installed on the second insulator;

[0009] By placing the power supply part on both sides of the insulator, current interference can be effectively reduced. At the same time, the balance stability of plugging and unplugging can be guaranteed, and more PIN pins can be accommodated to meet different signal transmission requirements.
