21、imensions and configurations: See figure 1. Connector mating: This connector mates with MS24266 and MS27615. The contacts shall be crimp type contacts and shall conform to SAE-AS39029 . Contacts are not assembled into the connectors, but are furnished separately in containers. The contacts shall be
22、crimped with a tool conforming to MIL-C-22520/1 crimping tool. For insert arrangements and alternate insert (keying) positions: See MIL-STD-1554. The dimensions and weight requirements shall be as specified in the tables shown on the MS drawings. Dust caps are supplied for front and back end of the
23、connectors. When the Part or Identifying Number (PIN) designates a cable support, the connector and cable support will be furnished unassembled. Materials and finishes: a. The shells shall be of stainless steel material. Type 300 series in accordance with DOD-F-24669/6 and shall be passivated in acc
24、ordance with MIL-STD-171. b. The contacts shall be of telnic bronze and shall be rhodium plated in accordance with SAE-AS39029 . c. The rigid insulation shall be of fired aluminum oxide (ceramic) material. d. Cable supports shall be of 310 stainless steel, casting alloy and shall be passivated in ac
25、cordance with MIL-STD-171. e. Contact retainers - material optional. f. Seals and grommets shall be of silicone rubber. For class K connectors: a. The connectors described herein shall meet all the environmental and electrical requirements of MIL-DTL-26500. b. In addition to the requirements of MIL-
26、DTL-26500, the connectors shall meet the following requirements. 1. Fireproof: A connector plug mated to its applicable receptacle assembly shall be mounted as used in service on a fixture fabricated in accordance with MIL-DTL-5015 and subjected to a 1,093C flame for a period of 60 minutes. The flam
27、e shall be directed at the connector, and shall completely encompass the connector. The temperature of the flame shall be measured at .250 inch, vertical distance from the rear of the connector. The flame shall be produced by using propane fuel with a high air-to-fuel mixture at a flow rate equivale
28、nt to an input of 33,000 to 37,000 BTU/HR. The assembly shall be vibrated continuously at 33 cps Hz with total excursion of .250 inch for 60 minutes. The contacts shall carry the following dc current for the first 5 minutes of the test. Provided by IHSNot for ResaleNo reproduction or networking perm

Throughout the test, there shall be
30、 no passing of Flames through the connector, nor shall there be any secondary combustion at the rear of the panel mounted connector. There shall be no adapters or extensions other than the standard cable clamp assembled to the connectors during the fireproof test. 2. Insulation resistance, fireproof
31、: After the flame test, the connectors shall be allowed to cool to room temperature, the mated connectors shall then be subjected to a test potential of 500 V dc. The insulation resistance of the connectors shall be greater than 2,000 megohms. 3. Dielectric withstanding voltage, fireproof. After exp
32、osure to the flame and insulation resistance tests, the mated connectors shall be subjected to 1500 V ac rms. Applied between adjacent contacts and the contacts closest to the shell, there shall be no evidence of breakdown or flashover. 4. Contact retention, fireproof after exposure to the flame, in
33、sulation resistance and dielectric withstanding tests, the individual contact locking mechanism shall withstand the axial loads specified in the table. Contact size Axial load (lbs.) (fireproof) 12 16 20 23 18 12 The load shall be applied to the contact as specified in MIL-DTL-26500 and shall be app
34、lied at a rate of one pound per second. All dimensions shown are in inches and are after plating dimensions. The four keys and/or keyways shall be within .004 of true position relative to the master key. The connector described in this MS drawing is classified as class K firewall connector. The shel
35、l sizes range from 12 to 28 and shall conform to the applicable portions of MIL-DTL-26500.
