ABSTRACT:
A waterproof ring for a connector housing of the threaded connection type, comprising spring members mounted integrally in a seal ring of a soft rubber material having an insertion hole for passing a tightening bolt therethrough; each of the spring members having a generally U-shaped pressure-receiving bent portion directed in a direction of an axis of the bolt, and inner and outer pressing portions provided respectively on opposite sides of said pressure-receiving bent portion. Therefore, the single seal ring can achieve not only the sealing effect but also the bolt-urging operation when tightening the bolt, thus providing advantages such as an improved sealing effect over the prior art, and an easier connection.
