Abstract
Abstract A guide wire assembly comprising a guide wire with first and second conductors which extend along the length thereof. The guide wire also comprises a flexible cable having first and second conductors which extend along the length thereof. A connector assembly is provided for interconnecting the flexible cable to said guide wire and interconnecting the conductors carried thereby. The connector assembly includes a male connector with a sleeve and a conductive core which is mounted in the sleeve. An insulator is mounted in the sleeve and insulates the conductive core from the sleeve. A conductive band is carried by the insulator and is spaced from the sleeve. The first and second conductors are disposed within the sleeve. The first connector is connected to the conductive core and the second conductor is connected to the conductive band. The connector assembly includes a female connector that has an inner conductive grip which has a cylindrical recess for receiving the conductive core and an outer conductor grip that has a cylindrical band which engages the portion extending forwardly of the inner conductive grip. An insulator is disposed between the inner and outer conductive grips. An insulating case is mounted on the outer conductive grip. First and second conductors are disposed within the case. The first conductor is connected to the inner conductive grip. The second conductor is connected to the outer conductive grip. The female connector receives the male connector and the first conductive grip receives the conductive core in the cylindrical recess of the first conductive grip. The second conductive grip receives the conductive band of the male connector by the cylindrical band receiving portion of the outer conductive grip engaging the band.
