Detailed Description

In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the waterproof structure of the side-out type SIM card socket in the prior art includes a face shell 11, a hardware push rod 12, and a sealing ring 13. The sealing ring 13 is sleeved in the hardware push rod 12 and then assembled in the SIM card needle jack 14 of the face shell 11, and the sealing ring and the side wall of the inner hole of the SIM card needle 15 are in interference fit movement to prevent external water vapor as shown by an arrow in fig. 2.

Foretell waterproof construction belongs to downthehole waterproof design, and in this design, five metals push rod 12 adopts CNC or lathe processing mode shaping, and sealing washer 13 adopts the oil pressure shaping mode, and two materials are assembled together to the rethread manual work. In this waterproof construction, manufacturing cost includes material cost and assembly cost, is 1.6 yuan of RMB probably, relatively speaking than higher, and the machining precision to spare part requires highly, and assembly and material require highly.

To the waterproof construction of the five metals push rod among the foretell prior art, this embodiment improves the waterproof construction of side play type SIM card needle jack, and the concrete improvement is as follows:

in this embodiment, the side-out SIM card pin jack waterproof structure shown in fig. 3 to 5 includes a face shell 21 and a silicone sealant pad 22.

The side of the face shell 21 is provided with a mounting groove 23, and a side-out type SIM card pin jack 24 is arranged in the mounting groove 23.

The shape of the silicone gasket 22 matches the collision of the mounting groove 23. The sealing silica gel pad 22 is arranged in the mounting groove 23 through a double-sided back glue 25. The thickness at the edge of the sealing silica gel pad 22 is the same as the depth of the mounting groove 23, so that the sealing silica gel pad 22 can be just clamped in the mounting groove 23.

As shown in fig. 6, the opening of the cross-shaped opening 26 is a point C, which is a point through which the SIM card needle passes, and the XY positive and negative directions are adopted at the point, which is favorable for the rebound, contraction and sealing of the silica gel. The overall width of the cross-shaped opening 26 is 1.5mm and the individual width of each side of the cross is 0.4 mm.

In addition, as shown in fig. 7, a cross-shaped opening 26 is provided on the silicone sealant pad 22 at a position corresponding to the SIM card pin insertion hole 24. The opening of the cross-shaped opening 26 is recessed inwards, the thickness of the silica gel at the lowest point of the recessed part, namely point A in figure 7, is 0.12mm, and therefore the SIM card needle can pierce the silica gel and cannot be stuck; the highest point of the depression, namely the thickness of the silica gel at the position B in the figure 7 is not less than 0.45mm, so that the integral strength of the sealing silica gel pad 22 is ensured.

As shown in fig. 8 and 9, the C point of the cross-shaped opening 26 corresponds to the position of the opening of the SIM card pin jack 24. When the SIM card pin 27 passes through the C point of the cross-shaped opening 26, the C point can utilize the high resilience and high toughness of the silicon gel and the fatigue resistance. After the SIM card needle 27 is inserted, the silica gel at the point C expands; after the SIM card needle is pulled out, the silica gel at the point C can be quickly reset to seal the SIM card needle jack 24, and external water vapor from the outside of the electronic product, as shown by an arrow in figure 9, can be blocked.

According to the side-out type SIM card socket waterproof structure in the embodiment, the effect of sealing the SIM card socket is realized by fixing the sealing silica gel pad outside the side-out type SIM card socket of the face shell through the double-sided back adhesive. In the sealing silica gel pad, a cross-shaped opening is arranged at a position corresponding to the SIM card inserting hole. The opening of the cross-shaped opening is inwards concave, the thickness of the silica gel at the lowest point of the opening is 0.12mm, and the thickness of the silica gel at the highest point is not less than 0.45 mm. The thickness design ensures that the SIM card needle can quickly penetrate through the silica gel and cannot be blocked, and the overall strength of the sealing silica gel pad is ensured. In addition, this sealing silica gel pad is through utilizing the high leakproofness fatigue resistance after the high resilience of silica gel and the resilience, and in addition the design of inside sunken cross opening can guarantee the sealed to SIM card hole. In addition, sealing silica gel pad sets up outside the face-piece, can promote after-sale maintenance yield, promotes after-sale stability and high efficiency, reduces after-sale cost.

In addition, the height of the edge of the sealing silica gel pad is the same as the depth of the mounting groove of the face shell where the SIM card jack is located, and the design can realize the waterproof and dustproof effects of the sealing silica gel pad on the whole mounting groove. In addition, in this waterproof construction, material cost and assembly cost are probably about 0.6 yuan RMB, compared with 1.6 yuan RMB among the prior art, the cost has saved 62.5%. Therefore, the waterproof structure in the embodiment can achieve the purpose of saving cost to the maximum extent on the premise of ensuring the quality and the protection capability.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their full equivalents, the present application is intended to include such modifications and variations.
