Abstract
An electrical connector includes a plug connector having a plug shell formed with a flange and a receptacle connector having a receptacle shell provided on its outer circumference with a fitting device. The electrical connector further includes a coupling ring surrounding the plug shell and rotatable and holding the flange of the plug shell. The coupling ring has on its inner circumference a fitting device fitted with the first mentioned fitting device and a flange urging portion for urging the flange. The electrical connector includes at least one wave-shaped annular spring interposed between the flange and the flange urging portion and rotatable together with the coupling ring. The wave-shaped annular ring and the flange are formed in their opposed surfaces with at least one protrusion and at least one recess, respectively, which are detachably fitted with each other, thereby forming a click lock device for causing the protrusion to fall into the recesses to produce click sound when the plug connector and the receptacle connector have been fitted. In an alternate embodiment, the electrical connector has some contacts connected to earth circuits which comprise earth lugs. The connector has a cylindrical shell, an insulator arranged in the cylindrical shell, and at least one contact detachably inserted in a piercing aperture formed in the insulator and connected to an electrical wire. The earth lug includes a first contacting portion contacting the cylindrical shell and a second contacting portion positioned in the piercing aperture and contacting the contact.
