2、tration has authorized the use of this commercial item description (CID). Abstract. This CID covers the general requirements for a polarized shell, plug, electrical digital interface bus connector. the IEEE 488 interface standard, and require termination of a 1.27 millimeters (.O50 inch) flat cable.
3、 This connector can be used in applications that require conformance to Application. 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 Numb
4、er (PIN). The PIN for the CID shall be as shown in the following example: o1 A-A-55154 - - I I I I II CID number Dash number Salient characteristics. Desian, construction, and dimensions. figure 1 and in accordance with IEEE 488. Design, construction, and dimensions shall be as specified on Contacts
5、. The contacts shall be formed of a high conductive, high strength copper alloy with gold over 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. Termination wire ran
6、qe. Terminations shall be insulation displacement type which accommodate 1.27 milllimeters (.O50 inch) centerline flat cable conductor with wire ranges of 26-30 AWG solid or 28 AWG stranded wire. Contact rating. Termination resistance. The contact resistance shall be 22 milliohms maximum initial for
7、 mated connectors Contacts shall be rated at 1 ampere maximum at +25C. and 12 milliohms initial for unmated connectors. Dielectric withstanding voltage. 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 as
8、semblies. Mating force. Unmatinq force. Durability. Connector mating force shall not exceed 3.12 newtons (0.7 pound) maximum per contact. Connector unmating force shall not exceed .89 newton (0.20 pound) minimum per contact. Durability shall consist of 200 cycles of mating and unmating and upon comp
9、letion the termination resistance shall not exceed a change greater than 10 milliohms maximum from the initial resistance. There shall be no indication of physical damage. Operating temperature. Vibration. The operating temperature range shall be from -4OOC to +75“C. The connector, or hardware when
10、assembled to the connector, shall exhibit no evidence of breaking, cracking, or loosening of parts when subjected to vibration of 10-55-10 Hz traversed in 1 minute at 2 millimeters (.O79 inch) total excursion for 2 hours in each of three mutually perpendicular planes.
