members are fastened together the second terminus 16 extending from the interface side 22 of the second connector 12 is inserted into the bore 24 in the first connector from the interface side 20 of the first connector and penetrates the alignment sleeve 36 through the open end 63 of the alignment sleeve 37 as shown in fig2 the alignment sleeve ensures that the two contact probes 26 40 from the two termini are properly aligned so as to properly align the fiber optic wires 25 39 within the probes the two contact probes contact each other at their distal tips 60 62 causing the contact probe 40 of the second terminus to move distally and thereby compress the belleville washers 18 between the sleeve 46 and the stop washer 50 which engages the second terminus expanding sleeve 48 consequently the compressed belleville washers 18 exert a force against the sleeve 46 forcing the second terminus probe 40 to maintain contact with the first terminus probe 26 simultaneously the sleeve 34 of the first terminus engages the expanding sleeve 36 of the first terminus as a result a desired distal biasing force is created by the spring action of the belleville washers when the connector is mated to a corresponding connector and a terminus abuts a corresponding terminus of the mating connector as the stop washer 50 and the sleeve 34 engage their corresponding expanding sleeves 48 and 36 they cause the expanding sleeves to expand and wedge in their corresponding bores 38 and 24 fixing the position of the termini relative to their corresponding connectors by.
