Product Overview

A custom micro usb cover closes an unused connector area with a fitted silicone rubber cap. Its shape should account for the connector orientation and the surrounding recess, which can differ between devices using the same interface. The cap needs a clear seating position and enough access to be removed without probing near the contacts.

Check the fit on the assembled device rather than on the connector alone. An enclosure wall can stop the cover early or hide the intended removal area. Size, material and color can be selected around that arrangement. Insert the cap squarely and avoid forcing it past resistance from an internal feature. Keep the portion entering the opening free of lint and loose debris before replacement. After removal, inspect for a split or material missing from a small edge. If the cap repeatedly tilts in its seat, review the actual housing profile instead of pushing it deeper. A correctly matched cover should return to its intended position through normal access and storage.

Material options
Custom silicone compound; formulation and geometry developed together.
Hardness selection
Silicone options: 20–80 Shore A. Insert the cap squarely and avoid forcing it past resistance from an internal feature.
Custom geometry
Its shape should account for the connector orientation and the surrounding recess, which can differ between devices using the same interface.
Fit evaluation
Check the fit on the assembled device rather than on the connector alone.
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.
