Description

A socket for inserting printed circuit boards

technical field

The utility model relates to the field of printed circuit boards (PCBs), in particular to a board holder for inserting and placing PCBs.

Background technique

The PCB needs to be stored, baked, and transported in the later stage of processing. At present, the common practice is to place the PCB in a plug-in rack. Generally, the board size of the board rack can be adjusted to meet the needs of different size PCB boards. However, the biggest disadvantage of conventional board racks is that the partition slots are fixed, so the thickness range and number of PCBs that can be inserted into each board rack are also fixed. Once the thickness of the PCB is not within the range of the partition groove, the PCB will be easily displaced or dumped to cause scratches on the board surface.

Detailed ways

In order to enable those skilled in the art to better understand the solutions of the embodiments of the utility model, the embodiments of the utility model will be further described in detail below in conjunction with the drawings and implementation methods.

As shown in Figure 1, it is a perspective view of the board holder for inserting PCBs of the present invention, and Figure 2 is a top view thereof.

In this embodiment, the board rack mainly includes: a three-dimensional rectangular support frame 101, a horizontal movable adjustment rod 102, and one or more vertical partitions and bottom partitions, the first vertical partition shown in the figure To the partition 103 and the second vertical partition 104, the bottom partition 202.

Wherein, the vertical partitions are horizontally installed on opposite side surfaces of the frame body 101 and have the same height on the horizontal plane.

As shown in Figure 1, a sliding device 107 that can move horizontally along the horizontally movable adjusting rod 102 is provided on the horizontally movable adjusting rod, and the vertical partition is installed on the sliding device 107, through which The sliding device 107 can move horizontally along the horizontally movable adjusting rod, and can be taken out from the sliding device 107 .

As shown in FIG. 2 , the vertical partition can be fixed on the sliding device 107 through a locking slot 201 . The sliding device 107 and the clamping groove 201 can be integrated or assembled with each other. The clamping groove 201 fixes the horizontal position of the vertical partition 104 so that the vertical partition 104 no longer moves along the horizontal position of the adjusting rod 102. direction to move.

In practical applications, the vertical partitions are preferably two corresponding pieces, as shown in 103 and 104 in Figure 1, and only one of them can be fixed (such as the first vertical partition 103 is fixed in the horizontal movable adjustment One end of the rod 102 is adapted to the size of the PCB board only by moving the vertical partition 104 in the horizontal direction. Of course, the partition slots 103 and 104 can also be moved in the horizontal direction.

The vertical partition can be extracted and replaced through the engaging slot 201 . The bottom of the support frame 101 is provided with a groove 106 for sliding of the bottom partition 202 . The bottom partition 202 can be strip-shaped or plate-shaped (it also needs to have a certain width when it is strip-shaped, so as to ensure sufficient pressure-bearing capacity), and there can also be multiple bottom partitions, especially when it is strip-shaped, two ( or above) the bottom partition can share the weight of the PCB board it carries. Preferably, the shape and spacing of the PCB slot on the bottom partition 202 are the same as the shape and spacing of the PCB slot 204 on the side vertical partition, and the positions are corresponding (considering that the PCB board is inserted vertically or placed obliquely) Insert placement). The bottom of the support frame 101 is provided with a positioning hole 203 for fixing the bottom partition 202 .

There are two horizontal movable adjustment rods 102, which are respectively located on two opposite sides of the support frame 101 and on the same horizontal plane, and can be completely fixed (such as welded) on the four longitudinal columns of the support frame 101, as shown in Figure 1 ; It can also be relatively fixed on the positioning holes of the four longitudinal columns by bolts and nuts. In a fully fixed state, the horizontally movable adjusting rod 102 is preferably located in the middle of the longitudinal rod, so that a PCB board with a smaller width can also be used. The horizontally movable adjusting rod 102 can be a circular cylinder or a rectangular cylinder.

Preferably, the sliding device 107 is provided with a nut 105, which can fix the sliding device 107 on the horizontally movable adjusting rod 102 and prevent it from moving in the horizontal direction. On the other hand, the clamping groove 201 and the vertical partition can also be fixed to each other by bolts (not shown in the figure) in the vertical direction, so as to fix the vertical position of the vertical partition to adapt to different sizes of PCB boards. For example, when the width of the PCB board is small, when it is placed vertically on the bottom groove 106, the vertical partitions 104 and 103 can be moved down slightly, and then fixed with nuts 105, so that the sides of the PCB board can be as close as possible. There may be more contact with the vertical partitions 104 and 103 to achieve a better positioning effect.

The PCB slots on the partitions are designed in different shapes according to different board thicknesses, as shown in Figures 3-5. For example, in Figure 3, the plate thickness below 1.0mm is designed as a "V" shape, the "V" shape opening is designed to be 3mm, and the spacing is 10mm. In Figure 4, the plate thickness is 1.0-3.0mm, the "V" opening is designed to be 5mm, and the spacing is 10mm. In Figure 5, 3.0mm to 6.0mm, the trapezoidal opening design is 9mm, the bottom design is 3mm, and the spacing is 10mm. The plate thickness above 6.0mm is also designed as a trapezoid, the opening design is 15mm, the bottom design is 6mm, and the spacing is 15mm. The trapezoidal slot can also be replaced by a U shape, that is, the bottom edge is arc-shaped instead of the straight edge. Design the shape and spacing of PCB slots on different partitions according to different board thicknesses. The shape and spacing of the bottom of the board holder are the same as the PCB slots on the side partitions, but the PCB slots on the bottom partition are strip-shaped.

Preferably, the PCB slot of the vertical partition is provided with an air vent 601 to improve the hot air exchange when the plate is baked. The layout of the vents is shown in Figure 6.

With the rapid development of the electronics and communication industry, PCBs are developing in diversification, and the demand for high-end HDI boards, ordinary multi-layer boards, and backplanes is increasing. The thickness of the PCB ranges from less than 1mm to 10mm or even 15mm. The utility model is used for inserting the groove body in the board holder of the printed circuit board, which can be easily disassembled, so the groove body with different widths can be easily replaced according to the board thickness of the PCB.

The above descriptions are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
