Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of circuit board end socket assembly, and in particular to a fixing structure without a snap-on socket at a circuit board end and a vehicle-mounted ceiling TV. Background Art

[0002] In the design and use of products, for example, in car ceiling TVs, the particularity of USB and HDMI signal transmission is used to transmit signals, especially for the transmission of high-resolution videos. In related products, there are strict special requirements for the selection of terminals, requiring buckles (that is, the male and female sockets can withstand vibrations and cannot be disconnected after being matched). However, such sockets with buckles are generally larger in size and much more expensive than ordinary sockets. Moreover, due to the particularity of the product, such sockets are generally directly exposed and plugged into USB or HDMI. Even if they are not exposed, they must be connected through a wire adapter with a male end socket to achieve the function. This socket with a buckle is inconvenient for connecting with the socket on the PCB board set inside the car ceiling TV. Therefore, it is necessary to design a socket that does not require a buckle for the socket on the PCB board end to save design costs. Utility Model Content

[0011] As a preferred solution, the end of the first socket away from the board-end socket is also connected to an external socket via a wire. In a car-mounted ceiling TV, the circuit board is generally arranged inside it. In order to facilitate the connection with an external USB or HDMI, the first socket is connected to the external socket via a wire, and the external socket is used to connect to the USB or HDMI, thereby realizing signal transmission. In some solutions, the structure formed by the connection of the first socket, the wire, and the external socket is a USB data cable or an HDMI data cable.
