All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 5, an embodiment of the present application provides a female socket device, which is applied to a board-to-board connector and is adapted to connect with a male socket device, and electrically connect two circuit boards after connection. The embodiment of the application aims to solve the problem that an extra physical structural component is required to be adopted between a female socket device and a male socket device of the existing board-to-board connector to realize a foolproof function or an identifier is added to prompt a butting direction, and therefore, the embodiment of the application provides the female socket device which mainly comprises a first socket component 1 and a second socket component 2, wherein the first socket component 1 comprises a first ground signal pin 10 and an electric signal pin, and the second socket component 2 comprises a second ground signal pin 20 and a protection pin, wherein the first socket component 1 is used for forward connection of a plug component in a first connection state, and the second socket component 2 is used for reverse connection of the plug component in a second connection state; the electric signal pin is used for connecting an electric signal interface of the plug component, and the protection pin is used for reversely connecting the electric signal interface of the plug component in the second access state. The electric signal pin is short-circuited to the protection pin during reverse connection, so that the protection of the device on the board is realized without changing the structure of a product or increasing the silk screen.

In one embodiment illustrated in fig. 1, the electrical signal pins include a first electrical signal pin 11 and a second electrical signal pin 12, the protection pins include a first protection pin 21 and a second protection pin 22, the first electrical signal pin 11 and the second electrical signal pin 12 are both disposed on the first socket part 1, the first protection pin 21 and the second protection pin 22 are both disposed on the second socket part 2, the position of the first protection pin 21 is aligned with the position of the first electrical signal pin 11 in a reverse direction, and the position of the second protection pin 22 is aligned with the position of the second electrical signal pin 12 in a reverse direction. The term "reverse alignment" as used herein means that the plug member, which is originally connected to the first socket member 1 in a forward alignment, can be aligned with the second socket member 2 in the second reverse state, i.e. the mutual position and arrangement of the first socket member 1 and the second socket member 2 support the reverse connection, for example, as shown in fig. 1-5, the two sockets are symmetrical and identical in shape and aligned in position, and the plug member, which is matched with the sockets, is also symmetrical and identical in shape and aligned in position.

According to an embodiment of the present application, the protection pin may be selected as a ground signal pin. The first socket part 1 and the second socket part 2 are both provided with ground signal pins located at the end parts, wherein the first ground signal pins 10 are located at two ends of the first socket part 1, the first ground signal pins 10 are bilaterally symmetrical and vertically symmetrical, similarly, the second ground signal pins 20 are located at two ends of the second socket part 2, and the second ground signal pins 20 are bilaterally symmetrical and vertically symmetrical. Particularly, the female socket device provides a plug between a first connection state and a second connection state, wherein the phase difference of the socket or the plug is 180 degrees, and the plug-in mode of reverse butt joint is exactly adopted.

It should be noted that, under the condition that the socket component and the plug component on the existing female seat device and the existing male seat device do not adopt the fool-proof structure, the socket component and the socket component of the same model can realize protective butt joint even if being reversely connected, so that the power signal pin is connected to the protective pin during reverse connection, and the protection of the devices on the board is realized under the condition that the product structure is not required to be changed and the silk screen is not required to be added.

In the present embodiment, the pins of the first socket member 1 and the second socket member 2 of the female socket device are assigned, and it can be understood that the pins of the first plug member 3 and the second plug member 4 of the male socket device mated with the female socket device are also assigned accordingly. After the pins on the first socket part 1 and the second socket part 2 are distributed, at least one protection pin is positioned on the second socket part 2 at the same position as the position of the electric signal pin on the first socket part 1 under the condition that the first socket part 1 or the second socket part 2 rotates by 180 degrees, and because the first socket part 1 is provided with the first ground signal pin 10 positioned on two end parts and the second socket part 2 is also provided with the second ground signal pin 20 positioned on two end parts, the ground signal pin can be normally connected with the plug under the positive connection state or the reverse connection state.

It can be understood that, when the female socket device of the embodiment of the present application is mated with the mating male socket device and in the reverse connection state, it is equivalent to that one of the female socket device or the male socket device is connected after rotating 180 degrees on the plane where the two are located, at this time, the first socket member 1 is mated with the second plug member 4, and at this time, the distribution position of each pin on the second plug member 4 is the same as the distribution position of each pin on the second socket member 2 after rotating 180 degrees, so that when the female socket device of the embodiment of the present application is reversely connected with the mating male socket device, at least one of the first electrical signal pins 11 is connected with the first protection interface 41 on the second plug member 4, the first protection interface 41 may be a ground pin, and at least one of the first ground signal pins 10 is connected with the fourth ground signal pin 40 on the second plug member 4, so that when the first electrical signal pin 11 is short-connected to the ground, thereby avoiding the generation of large current and realizing the purpose of protecting the device on the board.

Alternatively, the second electrical signal pin 12 may be selected to be one pin located at a single side, in which case, when the first socket part 1 or the second socket part 2 is rotated by 180 degrees, the second electrical signal pin 12 is located at the same position on the first socket part 1 as the second protection pin 22 is located on the second socket part 2.
