Assembled structure of mainboard and sub-board and terminal device

Abstract

The embodiment of the invention relates to the field of communication devices and discloses an assembled structure of a mainboard and a sub-board. An antenna bracket is arranged between the mainboardand the sub-board; the antenna bracket is provided with receiving slots for accommodating at least one elastic pin; both the mainboard and the sub-board are provided with metal contactors which correspond to the receiving slots and have the same number as the receiving slots; the elastic pins are respectively arranged in the receiving slots of the antenna bracket and respectively contact the corresponding metal contactors on the mainboard and the sub-board. In the assembled structure of the mainboard and the sub-board in the invention, the assembling process of the mainboard and the sub-boardis reduced; the cost is reduced; meanwhile, the production assembling difficulty is reduced; and the production efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication equipment, in particular to an assembly structure of a main board and a sub-board and terminal equipment. Background technique [0002] As the performance requirements of the current terminal equipment are getting higher and higher, the circuit design of its main board is also becoming more and more complicated. For example, in addition to the main board, conventional smartphones now generally have a sub-board, which also integrates various electrical components to meet different functional requirements. An antenna bracket is installed between the main board and the sub-board, and the connection is realized through FPC. [0003] However, the inventors have found that two connectors are generally required to connect the FPC between the main board and the sub-board, and the cost is high, and since the main board and the sub-board are generally located on both sides of the anten...

Problems solved by technology

[0003] However, the inventors have found that two connectors are generally required to connect the FPC between the main board and the sub-board, and the cost is high, and since the main board and the sub-board are generally located on both sides of the antenna bracket, the accuracy of the position is very demanding. High, it is often difficult to realize the installation, the assembly efficiency is very low, and it is easy to affect the production efficiency.
