28、s and for receptacles and connectors of single-rated Pin and Sleeve devices of the IEC 309-2 type, Series II. The dimensions shown defi ne the features which enable proper mating and mating of devices only with the same service, voltage, and amperage. The plug (or inlet) shroud shall have an externa
29、l key which mates with a keyway in the receptacle (or connector) cavity. The key/keyway is shown at the bottom of each confi guration. The ground contact is located from this point in 30 increments to provide discrete and predetermined contact patterns. The position of the female ground contact, whe
30、n viewed with the keyway at the 6 oclock position, is referred to as the clock position. There is a designated clock position for each voltage and service. These drawings do not show locking, sealing cord grip, or envelope clearance dimensions. a) The main view is shown with the grounding tube or pi
31、n at the 6 oclock position for reference only. See the rating confi guration for the required positions. b) Holes or recesses in the frontal face, if any, other than those for contact tubes, shall not have a depth of more than 0.394 inch (10 mm). See below. c) The dimension described in (b) shall no
32、t exceed the specifi ed limit at any point over the entire depth, and shall be within the specifi ed limits over a minimum depth of 0.236 inch (6 mm) with the exception of a maximum of: 1) three cut-outs for receptacles or outlets provided with 2 poles plus ground, 2) four cut-outs for receptacles o
33、r outlets provided with three poles plus ground, or 3) fi ve cut-outs for devices provided with three poles plus neutral plus ground, spaced around the circumference. There shall not be more than one cut-out between adjacent holes for the contact tubes and each shall not have a width exceeding 0.590
34、 inch (15 mm) including any radii. Holes deeper than 0.394 inch (1 mm) in the area are allowed, d) Pin detail dimensions refer to pin diameters. The contact tubes provide contact pressure and need not be cylindrical. e) The bevelling of the contact tubes may be rounded off toward the internal cylind
35、rical surface within a distance of 1-1/2 times the maximum dimension. f) Collars shall be provided for plugs or inlet devices having rated operating voltages exceeding 500 V. g) The ends of pins may be rounded off toward the external cylindrical surface within a distance of 1-1/2 times the maximum d
