Expansion Slot Cover 　Ground Wire If left for a long period without anything connected to the signal connector, dust may accumulate on the connector electrode, or rust may form on the metal surface due to condensation in winter, making it more likely that contact failure will occur when the connector is used later. We are receiving favorable reviews for our connector protection products, such as dust covers for connectors on shipped products, connectors without cables connected, preventing contact failure, and preventing the entry of insects. In addition, we are also receiving favorable reviews for preventing electrical and mechanical failures of connectors due to incorrect insertion of cables with different specifications by pre-sealing unused connector holes in business equipment. Furthermore, they are used in factories for dust prevention measures during product production and for protecting protruding connectors. They protect against dust, oil films, etc., during manufacturing and until shipment. Features: A low-cost plastic dust cap used to prevent foreign objects from entering the connector and damaging the screw parts.
