Embodiment approach 1

[0150] Embodiment 1, such as Figure 14A As shown, the distance adjustment structure 1423 includes a first installation part 1424 and a second installation part 1425 . The first installation part 1424 is connected to the first fixing part 1421 . The second installation part 1425 is connected to the second fixing part 1422 . The first installation portion 1424 defines a first installation hole 1426 . The second mounting portion 1425 defines a plurality of second mounting holes 1427 arranged at intervals. The locking member 1428 passes through the first mounting hole 1426 and the second mounting hole 1427 at different positions to adjust the distance between the first fixing portion 1421 and the second fixing portion 1422 . It can be understood that the plurality of second installation holes 1427 are arranged along the second direction. The second direction is perpendicular to the edge of the first edge region 1021 . At this time, when the locking member 1428 passes through...

Embodiment approach 2

[0152] Embodiment 2, most of the same technical content as Embodiment 1 will not be repeated: Figure 14B As shown, the distance adjustment structure 1423 is a sleeve. One end of the sleeve is connected to the first fixing part 1421 , and the other end is connected to the second fixing part 1422 . The distance between the first fixing part 1421 and the second fixing part 1422 is adjusted through the expansion and contraction of the sleeve. It can be understood that the sleeve has a plurality of sub-sleeves 1429 nested with each other. The plurality of sub-sleeves 1429 can expand and contract along the second direction. At this time, when the distance between the first fixing part 1421 and the second fixing part 1422 needs to be increased along the second direction, the innermost sub-sleeve 1429 can protrude relative to the outermost sub-sleeve 1429 . When the distance between the first fixing part 1421 and the second fixing part 1422 needs to be reduced along the second dir...

Embodiment approach 3

[0176] Embodiment 3, most of the same technical content as the previous embodiment will not be repeated: please refer to Figure 22 , Figure 22 Yes figure 1 A schematic structural diagram of yet another implementation manner of the circuit board assembly 14 of the terminal 100 is shown. The number of the first fixing part 1421 is one, and the number of the second fixing part 1422 is two. One first fixing part 1421 and two second fixing parts 1422 can be connected into an integral structure through the connecting part 104, and the structure can be T-shaped, triangular, etc. FIG.

[0177] In this embodiment, the firmness of the connection between the circuit board assembly 14 and the first structural member 12 and the second structural member 13 is increased by providing two fixing parts 1422, and the two fixing parts 1422 provided on the edge area 102 are aligned with the circuit board assembly 14. The board space of the board 141 is less affected by the arrangement of devi...

Abstract

The invention provides a circuit board component and a terminal. The circuit board component comprises a circuit board, an adaptive piece, a first fastening piece and a second fastening piece, whereinthe circuit board comprises a middle region and an edge region surrounding the middle region, and the adaptive piece is located at one side of the circuit board; the adaptive piece comprises a firstfixed part and a second fixed part connected with the first fixed part, wherein the first fixed part is located in the middle region, and the second fixed part is located in the edge region; the firstfastening piece is used for locking the first fixed part to a first structural piece, wherein the first structural piece is located at the side, facing the adaptive piece, of the circuit board; and the second fastening piece is used for locking the second fixed part and the circuit board to a second structural piece, wherein the second structural piece is located at the side, away from the adaptive piece, of the circuit board. The surface space utilization rate of the circuit board in the circuit board component is high. When the circuit board component is applied to the terminal, the space utilization rate of the terminal is high.

Description

technical field [0001] The present application relates to the technical field of electronic products, in particular to a circuit board assembly and a terminal. Background technique [0002] With the continuous improvement of mobile phone function requirements, the number of components on the circuit board in the mobile phone is increasing. At present, the circuit board in the mobile phone is usually placed between the front case and the back cover, and the circuit board is locked to the front case and the back cover at the same time through the screws penetrating the circuit board, and the front case and the back cover remain relatively fixed. However, when the front case or rear cover needs to be locked to the middle area of ​​the circuit board due to the limited shape, it is difficult to arrange components in the board area between the screw penetration position and the edge of the circuit board, resulting in wasted space on the board and the board of the circuit board Su...
