[0002] For existing electronic devices, temporary storage is often required in the processing and turnover process of unfinished products. At present, in order to achieve appropriate interval storage, corrugated cardboard or PC board is often used as a partition board.
[0003] However, corrugated cardboard is prone to chipping, which affects the cleanliness of electronic devices. PC boards have a general deformation effect, and when they are placed layer by layer, they are prone to squeezing electronic devices, especially electronic devices with pins, which are prone to deformation.
[0004] To address the above defects, foam partitions are currently used. However, foam partitions are prone to collapse and cannot be reset. After long-term use, the spacing effect will deteriorate and the defect of extrusion still exists.

[0021] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

[0026] 5BT resin layer DETAILED DESCRIPTION
[0027] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] like Figure 1 The PVC spacer sheet suitable for electronic devices includes a PVC substrate layer 1, which is different in that a flexible contact layer is distributed on the PVC substrate layer 1, which is convenient for appropriate deformation and avoids squeezing of electronic devices during spacing. Specifically, the flexible contact layer includes a plurality of flexible spacer bars 2, and a bearing bar 3 is distributed between the flexible spacer bars 2, and the heights of the flexible spacer bars 2 and the bearing bar 3 are consistent. In this way, when the flexible spacer bar 2 is deformed, the bearing bar 3 can reasonably support the entire flexible contact layer, so that it is in a suitable deformation state and will not collapse completely, so as to achieve reasonable barrier placement of electronic devices without hard squeezing. At the same time, a PVC bearing layer 4 is distributed on the flexible contact layer. In this way, the PVC substrate layer 1 can be cooperated to achieve clamping protection of the flexible contact layer, and when encountering electronic devices with pole feet, the sharp pole feet will not pierce the flexible spacer bar 2. From the perspective of the integrity of the combination, an adhesive layer (not shown in the figure) is laid between the PVC substrate layer 1, the flexible contact layer, and the PVC bearing layer 4. For some special use requirements, the bearing strip 3 can also be bonded to the PVC substrate layer 1 and the PVC bearing layer 4, so that the flexible spacer strip 2 has a larger deformation range. The adhesive layer is mainly epoxy resin, and various adhesives commonly used in the industry can be used, which will not be described here.
[0029] In view of a preferred embodiment of the utility model, the thickness of the PVC substrate layer 1 is 0.05 to 1 mm. During manufacturing, it can be preferably 0.1 mm. In this way, it has appropriate bending ductility. At the same time, in order to have a better deformation buffering effect, the flexible spacer strip 2 used is a silicone gel strip, and the load-bearing strip 3 is a rubber strip, and the thickness of the silicone gel strip and the rubber strip is 0.2 to 1.5 mm. In this way, the load-bearing strip 3 will not affect the deformation of the flexible spacer strip 2 due to being too hard, and has a seismic buffering effect. Through multiple comparative tests, it was found that the thickness of the silicone gel strip and the rubber strip is 1 mm, which can be deformed appropriately without causing excessive collapse, and will not cause stress pulling of the PVC substrate layer 1. Considering the stability of the contact, the cross-section of the flexible spacer strip 2 is rectangular, and the flexible spacer strip 2 is distributed with a number of deformation holes. In this way, during the pressure period, the stress can be absorbed by the deformation of the deformation holes to improve the buffering effect.
[0030] Further, the thickness of the PVC bearing layer 4 used in the present invention is 0.1 to 1 mm. For the isolation and placement of some thin electronic devices, the thickness may be preferably 0.6 mm. At the same time, considering the unified outer edge wrapping, the outer sides of the PVC substrate layer 1, the flexible contact layer, and the PVC bearing layer 4 are infiltrated with a BT resin layer 5.
[0031] The working principle of the utility model is as follows:
[0032] Embodiment 1: lateral spacing.
[0033] For larger electronic devices, after they are placed in the storage box, the utility model is used to vertically insert them into each other and distribute them one by one.
[0034] During transportation, possible lateral stress is absorbed by the deformation of the flexible contact layer. If the stress impact is too large, the stress transmitted by the electronic device causes the flexible contact layer to deform, thus achieving a flexible storage interval for the electronic device.
[0035] Embodiment 2: longitudinal spacing.
[0036] For some thin-sheet electronic devices with pins, they are spaced apart layer by layer with the present invention. Due to the existence of the flexible contact layer, there will be no hard extrusion. In this way, they can be stacked and stored without damage.
[0037] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:
[0038] 1. An independent flexible contact layer is provided, which can be deformed appropriately, absorb external stress, and avoid mutual squeezing of electronic components.
[0039] 2. The PVC base material layer and the PVC bearing layer provide appropriate spacing protection to prevent sharp pins from piercing the flexible contact layer.
[0040] 3. The flexible contact layer is provided with a bearing strip, which can deform appropriately without excessive collapse.
[0041] 4. The overall structure is simple, will not produce chipping, and will not pollute electronic devices.
[0042] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
