As shown in fig. 1, the integrated female header of the integrated converter is configured to be disposed on a PCB, and a plurality of pins and sockets corresponding to the pins are disposed in the female header.

These pins include, as shown, a JTAG interface, a UART interface, and a USB interface, respectively, as well as a VCC interface for connecting an operating voltage and a GND interface for grounding.

JTAG interface, mainly used for chip internal test. Most advanced devices now support the JTAG protocol, such as DSP, FPGA devices, etc. The standard JTAG interface is 4-wire: TMS, TCK, TDI, TDO are mode selection, clock, data input and data output lines respectively, therefore for the integration mother head of the application, a plurality of interface lines of JTAG are integrated on one pin, and data communication of JTAG interfaces is realized.

UART is a universal serial data bus used for asynchronous communications. The bus is in bidirectional communication, and full duplex transmission and reception can be realized. In embedded designs, the UART is used to communicate with the PC, including communicating with a supervisory debugger and other devices, such as an EEPROM (Electrically Erasable Programmable read only memory), and the like. When an internal module which needs to perform data communication through the UART exists on the PCB, the internal module needs to be connected with an upper computer through the UART interface.

USB is a universal serial bus, which is an external bus standard used to standardize the connection and communication between computers and external devices. The USB interface is the most common daily PC interactive interface, and at present, some modules arranged on some PCBs support the USB interface, so that the USB interface is adapted to the USB interface, for example, USB interfaces are also arranged on mainboards of a router and an intelligent gateway, and a user can insert the USB interface to perform data processing.

In summary, when a functional module on a PCB is complex, there may be multiple data interfaces, and each interface is set, the wiring of the PCB needs to be adjusted, and a new space is provided to set a new interface, and the interfaces are integrated together and implemented by one interface, so that the occupied space can be greatly reduced, and the trouble of wiring is reduced.

And because the interface type that every pin corresponds is different, when setting up this integration female head to PCB board one, need aim at each pin, can not put upside down, therefore can through to 1 pin department in the integration female head prevent slow-witted design, for example 1 pin place one side design a marking line, or make a arch or breach, to show here is a pin, need connect VCC power. Therefore, when the integrated female head is assembled, the integrated female head can be loaded on a PCB in a correct direction and a correct wiring mode.

In addition, in order to guarantee that the integrated male connector can not be connected reversely when being connected, the integrated female connector is provided with a clamping groove 100, the clamping groove 100 is used for performing stable action when the integrated female connector and the integrated male connector are connected and preventing falling off, the clamping groove is arranged on two opposite sides of the integrated female connector, as shown in fig. 1, the clamping groove can be arranged on the front side and the rear side and is asymmetrically arranged for preventing staying and preventing reverse insertion of a user when the integrated male connector is connected.

Specifically, as shown in fig. 1, there may be one groove on the front side and two grooves on the back side, and in an alternative embodiment, the clamping grooves 100 may be disposed on the left and right sides, for example, one groove on the left side and two grooves on the right side. Or two on the left side and three on the right side. Or a mirror image arrangement as described above.

In an alternative embodiment, the shape of the latch recess 100 may be different, for example, the latch recess 100 disposed at the front side is square, and the latch recess 100 disposed at the rear side may be elongated, so as to prompt the user of the insertion direction of the integrated male tip.

The number, shape, style and size of the specific clamping grooves 100 may vary according to the situation, and the application is not limited thereto.

As shown in fig. 2, an integrated male head is provided for an embodiment of the present application.
