Problems solved by technology

[0003] However, in the assembly process of the mobile phone, the process of screw fixing is usually carried out at the last stage. If it falls during the screw connection process, it will be left on the main board or circuit board due to reasons such as difficulty in taking it out or not being aware of it. This can easily cause a short circuit of other electronic devices and cause a safety accident of the whole machine

Abstract

The invention provides electronic equipment and a circuit board assembly thereof. The circuit board assembly comprises a circuit board, a BTB connector and a pressure plate assembly. The BTB connectoris fixedly arranged on the circuit board. The pressure plate assembly comprises a main pressure plate and a first auxiliary pressure plate. The main pressure plate is provided with a gap; the first auxiliary pressure plate is provided with an opening corresponding to the gap; and an accommodation clearance is arranged between the gap and the opening. According to the circuit board assembly, by arranging the opening in a raised portion of the first auxiliary pressure plate, stress condition of a clamp connection portion can be improved, thereby ensuring uniform stress of a second side wall andallowing clamping and separating operation of the clamp connection portion and the auxiliary pressure plate to become simpler and labor saving.

Description

technical field [0001] The invention relates to the technical field of a board-to-board connector fixing structure of an electronic device, in particular to an electronic device and a circuit board assembly thereof. Background technique [0002] Terminal electronic devices such as mobile phones and tablet computers usually need to connect two or more circuit boards through BTB (Board To Board, board-to-board) connectors. For example, in the mobile phone structure, the sub-circuit board carrying or connected with functional components is usually electrically connected to the main board through the BTB connector. However, the BTB connector often has the problem of instability, which makes the circuit board and the main board easily disconnected. The commonly used method in the prior art is to directly screw the BTB connector to the motherboard through screws, and share the screw pressure to the BTB connector, thereby enhancing the stability of the BTB connector; or cover the B...
