Abstract

A male coaxial connector adapted for receiving a female connection member. The male coaxial connector defines an axial direction along its major axis. The male coaxial connector includes a spring basket biased towards an open position which is positioned around a male connection member. The spring basket is adapted for engaging the female connection member. The male coaxial connector also includes a sleeve reciprocally positioned around the spring basket and the male connection member. The sleeve is movable in the axial direction with respect to the spring basket such that when the sleeve is in a forward position or rearward position with respect to the spring basket, the spring basket is in an open position. The female connection member can be released from or inserted into the spring basket when the spring basket is in its open position. When the sleeve is in a neutral position with respect to the spring basket, the sleeve is in engagement with the spring basket forcing the spring basket into a closed position such that the spring basket applies a radially compressive force on the female connection member. The male coaxial connector also includes a first spring positioned around the male connection member. The first spring provides an axial force on the male connection member which forces the male connection member into engagement with the female connection member.
