fig. 2 is a sectional view of the waterproof cushion of the present invention along the sectional line a-a.
Detailed Description
The technical solution of the present invention is further described below by way of examples:
the utility model provides a FPC's waterproof cushion, as shown in FIG. 1, waterproof cushion includes: the positioning frame 1 and the extension frame 2, the positioning frame 1 and the extension frame 2 are communicated, the width of the positioning frame 1 is larger than that of the extension frame 2, the length of the positioning frame 1 is smaller than that of the extension frame 2, both the positioning frame 1 and the extension frame 2 are provided with a bottom plate and a frame, and both the positioning frame 1 and the extension frame 2 are formed by foam. At the time of assembling the waterproof cushion, the chip circuit portion of the FPC is mounted in the positioning frame 1 and forms an interference fit, and the transmission circuit portion of the FPC is mounted in the extension frame 2 and forms an interference fit, thereby fixing the FPC in the waterproof cushion. Waterproof cushion can prevent effectively that moisture from getting into FPC in, avoids signal transmission to receive the influence of moisture, in addition, because positioning frame 1 all forms by the bubble cotton with extension frame 2, consequently waterproof cushion can be crooked along with FPC, can not reduce FPC's degree of freedom.
Specifically, a plurality of positioning pins 11 protrude from the inner surface of the frame of the positioning frame 1, and the positioning pins 11 extend from the frame of the positioning frame 1 to the inside. The chip circuit part of the FPC is fixed between the positioning pin 11 and the bottom plate of the positioning frame 1 to form stable positioning, and even if a worker overturns the waterproof cushion for many times, the chip circuit part of the FPC cannot fall out, so that the operation is convenient.
Specifically, as shown in fig. 2, the lower surface of the positioning frame 1 has a hardened layer 12, and the hardened layer 12 is formed of hard cotton. Since the chip circuit portion of the FPC generally has many components, providing the hardened layer 12 can effectively protect the chip circuit portion of the FPC from damage due to a collision or the like.
Specifically, the frame upper surface of the positioning frame 1 is sequentially provided with a first adhesive layer 14 and a first release film 15. The positioning frame 1 can be fixed to the circuit substrate by the first adhesive layer 14.
Specifically, with continued reference to fig. 1, the upper surface of the frame of the extension frame 2 has a cover plate 21. When the transmission circuit portion of the FPC is mounted, the cover 21 may be opened, and after the transmission circuit portion is placed in the extension frame 2, the cover 21 may be closed. The cover plate 21 is fitted to the extension frame 2, and can completely surround the transmission circuit portion, thereby improving the waterproof effect. In addition, the cover plate 21 can further fix the transmission circuit part, thereby facilitating the operation of workers.
More specifically, the extension frame 2 has two side frames and two cover plates 21, and the two cover plates 21 are disposed opposite to each other. The elastic restoring force of the two cover plates 21 is greater, providing a more stable fixing effect.
More specifically, the extension frame 2 has a groove 22 on the outer surface of the rim thereof, and the groove 22 and the cover plate 21 are parallel to each other. The provision of the groove 22 increases the amount of deformation of the frame, facilitating the opening and closing operation of the cover 21.
Specifically, with reference to fig. 2, the second adhesive layer 24 and the second release film 25 are sequentially disposed on the upper surface of the cover plate 21. The extension frame 2 can be fixed at any position of the electronic device through the second adhesive layer 24, and arrangement operation of workers is facilitated.
Therefore, the waterproof cushion with the structure can effectively prevent moisture from entering the FPC, avoids the influence of moisture on signal transmission, can be bent along with the FPC, and cannot reduce the freedom degree of the FPC.
