Connectors covered by this CID are intended for commercial/industrial applications and may be used in military systems where individual environmental and performance requirements can be met. Part or Identifying Number (
4、PIN). The PIN for the CID shall be as shown in the following example: A-A-55155 - JI- I I I I II CID number Dash number Salient characteristics. Design, construction, and dimensions. Design, construction, and dimensions shall be as specified on figure 1 and in accordance with IEEE 488. Contacts. The
5、 contacts shall be formed of a high conductive, high strength copper alloy with gold over O nickel plating in the contact area. Connector housings. Connector housings shall be molded from self-extinguishing black thermoplastic material for high impact and dielectric strength. Connector shields. Conn
6、ector shields shall be made of die cast zinc with nickel plating. Connector hardware. Connector hardware shall be of zinc plated carbon steel. Termination wire range. Terminations shall be insulation displacement type which accommodate 1.27 mm (.O50 inch) centerline flat cable conductor with wire ra
7、nges of 26-30 AWG solid or 28 AWG stranded wire. Contact rating. Contacts shall be rated at 1 ampere maximum at +2SoC. Termination resistance. The contact resistance shall be 22 milliohms maximum initial for mated connectors and 12 milliohms initial for unmated connectors. Dielectric withstanding vo
8、ltage. There shall be no breakdown of the insulating material when subjected to 1000 V ac for 1 minute between adjacent contacts of the mated connector assemblies. Mating force. Connector mating force shall not exceed 3.12 newtons (0.7 pound) maximum per contact. Unmating force. Connector unmating f
9、orce shall not exceed .B9 newton (0.20 pound) minimum per contact. Durability. Durability shall consist of 200 cycles of mating and unmating and upon completion the termination resistance shall not exceed a change greater than 10 milliohms maximum from the initial resistance. There shall be no indic
10、ation of physical damage. Operatina temperature. The operating temperature range shall be from -4OOC to +75OC. O AMSC N/A DISTRIBUTION STATEMENT A.
