MIL-C-5015 Connectors MS-E/F/R/ER Performance and Material Specifications High Voltage Cartridges for MS-E and MS-R (HV310*E/R Series) For class E, R and F connectors, satisfactory mois- ture sealing will be obtained if AWG and MS wire sizes and insulation outside diameters are governed by this table. Test current ratings of contacts and allowable voltage drop under test conditions when assembled as in service are shown below. Maximum total current to be carried per connector is the same as the allowable in wire bundles as specified in MIL- W-5088. Pin and socket contacts are designed to resist severe vibration and repeated connection and disconnection. The average force to either engage or separate pin and socket contacts will not exceed the average values given in the latest revision of MIL-C-5015. Sizes 12 and 16 contacts, machined from matching thermocouple lead wire alloys, can be supplied in ITT Cannon connectors. These thermocouple contacs maintain continuity from thermal-sensor leads thru a bulkhead of other closures in temperature measuring applications. These contacts for matching lead wires are detailed by the standards of the Instrument Society of America (I.S.A); Since the thermocouple connector applications determines the soldering methods and materials to be used, thermocouple contacts, identified by permanent markings, are normally supplied with untinned solder pots. Thermocouple contacts are supplied only in connectors having resilient insulators. MS connectors show no evidence of breakdown when the test voltage given below is applied between the two closest contacts and between the shell and the contacts closest to the shell for a period of one minute.

Previ- ously, MS connectors involved in high voltage cir- cuitry required individual design considerations and could only be ordered as a "special." The new high voltage cartridge allows conversion of a standard connectors to one capable of handling up to 15,000 volts DC (Test Voltage - mated), operating voltage - See level 5,000 VDC or 3,500 VAC. These cartridges are molded of nylon and provide as high degree of arc-over protection between adjacent contacts or between a contact and the connector shell. Unmated, each cartridge provides a nylon isolating barrier capable of withstanding up to 10,000 volts DC (or peak). The contact within the cartridge is a 7.5 amp. size 20, crimp snap-in type with dielectric rear release clip retention. This contact is removable with the plastic CIET20 insertion/extraction tool provided the insulation is .084 (22.45) or less. The contact may be crimped with the standard MS-3191 tool and MS-3191-20A locator and hand inserted into the nylon cartridge. The cartridge body is installed in the connector at the factory. High voltage cartridges now available fit the space normally occupied by a #4 o #8 size contact in an MS-E, MS-R or MS-F type connector. Over forty-nine contact arrangements are currently available in which these high voltage cartridges may be used. Contsult factory for ordering information. |
