Embodiment Construction
[0038] The core of the present invention is to provide a double-layer circuit board system. This system finds another way to optimize the structure of the plug-in assist mechanism. The light design provides reliable protection, while effectively improving the operability of plugging and unplugging operations. The present embodiment will be described in detail below in conjunction with the accompanying drawings.
[0039] Without loss of generality, this embodiment will be described in detail mainly by taking the large-sized main circuit board and the small-sized pinch board as the main body. It should be understood that the plug-in assisting mechanism formed based on the main body is also applicable to the double-layer circuit board design solutions with other size ratio relationships.
[0040] See image 3 , which is a schematic diagram of the overall structure of the double-layer circuit board system in this embodiment. The two-layer circuit board system shown in the figur...

The invention discloses a double-layer circuit board system. The double-layer circuit board system comprises a power-assisting mechanism which is used for plugging and unplugging a connecting assembly along a first direction, wherein the power-assisting mechanism comprises two handles which are hinged with a main circuit board and two connecting rods which are hinged with the two handles; a first sliding fit pair which slips along the first direction is arranged between a pinch plate and the main circuit board, and a second sliding fit pair which slips along a second direction is arranged between the pinch plate and the first handle and / or the second handle; the first sliding fit pair positioned on a plug-to-be working position is adaptive to a first position, and the second sliding fit pair is adaptive to the first position; the first handle and the second handle can respectively rotate around a first hinging point and a second hinging point respectively to a plugging working position; the first sliding fit pair positioned on the plugging working position is adaptive to a second position in a relatively sliding manner along the first direction, and the second sliding fit pair is adaptive to the second position in a relatively sliding manner along the second direction. The double-layer circuit board system has the characteristics of compact structure and good operability. On such basis, the invention further provides an electronic terminal with the system.
Description
technical field [0001] The invention relates to a double-layer circuit board assembly technology, in particular to a double-layer circuit board system and an electronic terminal using the system. Background technique [0002] In the prior art, a daughter board (sub-circuit board) is usually installed on a main circuit board to expand the capability of the circuit board or realize the application of circuit board modularization technology, wherein the main circuit board and the daughter board pass through Connectors connect power and signals. [0003] See figure 1 , which shows the traditional way of assembling the main circuit board and the daughter board. [0004] like figure 1 As shown, several supporting columns are fixedly arranged on the main circuit board, and then the sub-board is fixed on the supporting columns of the main circuit board with screws. Among them, some or all of the supporting columns adopt elastic clamping columns with a limit function to improve a...
