Silicone USB dust cap dust cover for cell phone/computer/memory

A silicone USB dust cap can be customized for a cell phone, computer, or USB memory product. The intended interface must be identified precisely because covering a device port and covering an exposed connector require different engaging shapes. The finished cap should follow the selected product rather than be assumed to suit every USB application.

For a memory product, include the connector projection and the surrounding body in the fit assessment. For a phone or computer, include the housing recess and access for removal. In either case, the cover should not place unwanted force on the electrical contact area. The exposed face can be sized and colored to coordinate with the product.

Storage conditions also affect care. Keep the inner contact area of a removed cap away from loose dirt so it is ready for refitting. Inspect for damage before using a cap that has been carried separately. A correctly matched version should seat in its normal orientation without stretching or bending to make up for a different connector shape.
