Unless otherwise specified, tolerance is + .016 inch (0.41 mm) and + on angles. 4. Seven contact cavities equally
5、spaced throughout 270 of arc, and each cavity located within of true position, shall be established along the pin circle. 5. Each contact tab shall have either: a. 1 wire hole of .040 inch (1.02 mm) minimum width and .125 inch (3.18 mm) minimum length. b. Two holes of .040 inch (1.02 mm) minimum wid
6、th and .075 inch (1.91 mm) minimum length. The contact tab hole, or holes shall lie on the longitudinal centerline of the contact tab within + .008 inch (0.20 mm). 6. The design of bosses and the shape of barrier, when use, are optional. When present, barriers shall have a maximum height of .062 inc
7、h (1.57 mm). 7. Clearance between the cavity wall and the contact, with the contact in any position, shall be no greater than .018 inch (0.46 mm). 8. Marking shall be at any convenient visible location. 9. Material thickness of mounting flange shall be measured in an area where burring or dishing of
8、 the mounting hole is not present. FIGURE 1. Socket configuration Continued. REQUIREMENTS: Dimensions and configurations: See figure 1 and table I. Insulating material: Ceramic, Diallyl Ortho-Phthalate in accordance with ASTM PS 15 type, SDG-F, GDI-30F, or mineral-filled Phenolic resin in accordance
9、 with ASTM D5948 type MFE, see table I. Contact cavities: One shape only; D-shaped or circular, at option of the manufacturer. Float: With a pin of .041 inch (1.04 mm) diameter and .271 inch (6.88 mm) minimum length fully inserted in a socket contact, the contact shall be capable of free movement (f
10、loat) within the contact cavity. Saddle: The method of attaching the saddle to the insulator body, and the shape of the saddle where attachment is effected, are optional.

Test pin diameter .040 + .001 inch (1.02 + .03 mm). High altitude: Test voltage: 660 volts ms. Test pin dia
12、meter: .040 + .001 inch (1.02 + .03 mm). Contact resistance: Average for all contacts: 0.015 ohm maximum. Individual contacts: 0.03 ohm maximum. Continuity test circuit: With the header test-gage(s) inserted into the socket(s) under test, the pins of the test-gage(s) and the contacts of the socket(s
13、) under test, shall result in a series circuit. The header shall be the one used for electron tube 6AU6WB. Mechanical: Insertion and withdrawal force: Initial insertion force: 15 pounds (67 newton) maximum. Average insertion force: 12 pounds (53 newton) maximum. Initial withdrawal force: 4 pounds (1
14、8 newton) minimum, 12 pounds (53 newton) maximum. Vibration: The test gage shall be an approved electron-tube type 6AU6WB, in accordance with MIL-E-1/952. Durability: After the durability test, the withdrawal force shall be 2 pounds (9 newton) minimum. Static load: 40 pounds (178 newton). The part s
