14、A REV A PAGE 7 Figure 1. Dimensions and configuration Continued. SCOPE This is an extended environment-resisting hybrid construction (metal and nonmetallic inner shell components, nonmetallic coupling nut) backshell. Metallic components are finished with olive drab cadmium plate over a suitable unde

15、rplate. Nonmetallic components are uncoated for corrosion resistance. REQUIREMENTS Backshells shall meet the requirements of MIL-C-85049, category 3C, class W with the following exceptions and additions. Dimensions and configuration: See figure 1 for interface dimensions that shall confirm to MIL-DT

16、L-38999, series III. Salt spray (corrosion): The backshells shall meet the dynamics salt spray requirements of MIL-C-85049, with the following exceptions and additions. The backshells shall be tested 2000 hours. Hydrolytic stability: The backshell shall be subjected to the following tests: a. Measur

17、e backshell weight. b. Boil in distilled water until no further weight gain is observed. c. Backshell may be dried with filtered compressed air. d. When backshell weight has stabilized, measured percent total weight gain, mating dimensions and length. e. Backshell shall be tested in accordance with

18、the thread strength of MIL-C-85049, category, 3C. e. Inspection of the backshell for damage. The backshell shall be without defects detrimental to mechanical performance. Total weight gain shall be less than 0.75 percent. When subjected to coupling thread strength specified in MIL-C-85049, there sha

19、ll be no evidence of cracking, breaking, or loosening of parts. Lighting strike: Backshells mated with matched construction connectors shall be subjected to a simulated lighting current pulse exposure. The current pulse shall be applied by a suitable high current generator and the current Provided b

21、ope. The test pulse shall be a damped sinusoid with a basic frequency of 21 kHz and an amplitude decay time of 140 microseconds to 37 percent of its peak value. Pulse amplitude decay time of 140 microseconds to 37 percent of its peak value. Pulse amplitude shall be 60 kA. The receptacle connector sh

22、all be mounted on a simulated panel, using its normal mounting provisions. The simulated current pulse shall be applied between the plug accessory and the receptacle mounting panel. Upon completion of the pulse application, and without disturbing the test sample, the shell-to shell conductivity test

23、 of MIL-DTL-38999 shall be performed. When the electrical measurements have been completed, the sample shall be inspected in both the mated and unmated condition for evidence of damage from the simulated lighting current pulse. Part or Identifying Number (PIN): The PIN shall be in accordance with th

24、e following example: 89110- 11 E 1 Drawing number Shell size Cable entry size code Length code Marking: Marking shall be in accordance with MIL-C-85049 except the PIN shall be as stated above. Application guidance: To obtain full extended performance as specified above, this backshell must be assemb

25、led with the application hybrid connector, as specified on drawing 89090, 89093, and 89094. QUALIFICATION Qualification inspection: Qualification inspection for the backshells specified herein shall not be required. Qualification conformance inspection: Shall be in accordance with MIL-C-85049, unles

26、s otherwise specified. Inspection of packaging: Shall be in accordance with MIL-C-85049, unless otherwise specified. Methods of inspection: Shall be in accordance with MIL-C-85049, unless otherwise specified. Approved sources of supply. Approved sources are listed herein. Additional sources will be
