Connector

A connector for interconnecting or mutually isolating two or more electrical circuits, comprising first and second inter-engageable connector parts, the first part comprising a spigot extending along an axis and at least one first contact for connection to a respective electrical circuit, the second connector part comprising a socket into which the spigot is to be inserted and at least one second contact for connection to a respective electrical circuit, the second part supporting at least one member projecting radially into the socket, the first part defining at least one groove for receipt of the member, a first contact holder of electrically insulating material carrying the at least one first contact and a second contact holder of electrically insulating material carrying the at least one second contact, wherein the first contact holder has a first shroud disposed around the at least one first contact, the first shroud extending axially beyond the at least one first contact, and the second contact holder has a second shroud disposed around the at least one second contact, the second shroud extending axially beyond the at least one second contact, the contact holders being arranged such that when the spigot is received in the socket, the connector parts are moveable between a first axial position in which one of the first and second shrouds is received within the other of the first and second shrouds but the first and second contacts are axially separated and a second axial position in which one of the first and second shrouds is received within the other and the first and second contacts are engaged.
