Product Overview
A silicone micro USB cover closes the opening around a small connector when the port is not in use. Its shape needs to suit the enclosure recess as well as the connector position, because the protective interface is formed where the cover meets the housing. A cap that presses against the connector before seating can leave the surrounding opening incompletely closed.
For a custom design, allow space to lift the cover without pulling on the socket or levering against a thin housing edge. Check the open position with the intended cable attached: the cover should not push the plug sideways or prevent full insertion. If a retaining feature is included, its location must accommodate that movement without repeated sharp bending.
Water exclusion depends on the finished enclosure, mating surfaces, and cover fit, so assess it on the complete product under its intended exposure conditions. Before closing the port, remove trapped debris and allow any moisture to clear. A damaged seating edge or cover that no longer stays fully engaged should be corrected before the opening is relied on for protection.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Check the open position with the intended cable attached: the cover should not push the plug sideways or prevent full insertion.
- Custom geometry
- A cap that presses against the connector before seating can leave the surrounding opening incompletely closed.
- Fit evaluation
- A damaged seating edge or cover that no longer stays fully engaged should be corrected before the opening is relied on for protection.
- Color & OEM
- Custom colors; identification clear of connectors and removal features.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
