3、ft storage batteries. The plug shall mate with the pins of MS3509-series receptacles to meet mechanical engagement and electrical resistance requirements. 2. Dimensions and weight. The dimensions and weight of the plug shall be as specified in 3.12.3 of MIL-PRF-18148 and 3.12.4 as modified herein an
4、d as shown on figure 1 contained herein. 3. MIL-PRF-18148 variance. The plug shall comply with MIL-PRF-18148 except as follows. 3.1 Modify the following paragraphs: 3.8.2 Electrical connections. Insert after the first sentence: “Each four-wire MS25182-2 plug shall include as its electrical connectio
5、ns four sockets with their axes horizontal and in a plane parallel to the face of the receptacle. Each plug shall be usable with four 000-gauge wires conforming to SAE-AS50861/2 for Type 2. Each plug shall include four wire entry holes on the sides, through which the wires may be brought into the so
6、ckets. Each plug shall be made so that the wires shall enter it horizontally and in a plane parallel to the face of the receptacle. Each plug shall be made so that the wire which enters the left wire entry hole, as viewed looking at the front (handle) face of the plug, can be connected to the negati
7、ve contact only, and the wire which enters the right wire entry hole can be connected to the positive contact only. “-“ and “+“ shall be marked on the front, back, bottom, or sides of the plug so as to identify the wires connected to INCH-POUND Provided by IHSNot for ResaleNo reproduction or network

Each plug shall include two setscrews for retaining the wires in the sockets that can be accessed after removing
9、 the cover of the plug. Each plug shall include two threaded terminals for retaining the wires in the sockets The axes of the threaded terminals shall be perpendicular to the face of the receptacle. Each threaded terminal shall include a hexagonal wrenching socket. Each plug shall include two wrench
10、 entry holes on the front face, and shall be made so that the threaded terminals can be operated by a wrench inserted in the wrench entry holes. No part of the electric circuit of the plug shall be exposed except through the wire, wrench, and contact entry holes.“ 3.10.1 Delete this paragraph. 3.12.
11、4 Weight. Insert after the first sentence: “The weight of each four-wire MS25182-2 plug shall be not greater than 1.10 pounds.“ VERIFICATION 1. MIL-PRF-18148 variance. The plug shall comply with MIL-PRF-18148 except as follows. 4.2 Qualification inspection. Insert after the end of the first sentence
12、 “(see table I of the specification sheet).“ 4.3 Conformance inspection. Insert after the end of the first sentence: “(see table I of the specification sheet).“ 4.5.5 Plug preparation procedure. Insert as a new first sentence: “Whenever electric connection must be made to the plug, four 000-gauge w
13、ires conforming to SAE-AS50861/2 for Type 2 shall be connected to the plug in accordance with 3.8.2 as modified by MIL-PRF-18148/2.“ 6.9 Supersession data. Delete the text and insert. “Connector plugs previously procured to MS25182 are superseded by MIL-PRF-18148/2”. 6.10 International standardizati
