22、1-4:1997 BSI 12 February 2002 3 1 Scope and object This section of IEC 60512-1 is to be used when referenced by the detail specification to test mechanical components overseen by the IEC subcommittee 48B. This test can also be done on similar devices when the detail specification so prescribes. The

23、object of this test is to define a standard test method to verify the ability of a connector to prevent the accidental touching of its contact by the front of the mating connector. It is primarily intended to be applied to cylindrical multi-contact connectors which are required to be scoop-proof. 2

28、 BSI 12 February 2002 4.2 Method A While attempting to mismate the free connector, fitted with female contacts to the fixed connector fitted with male contacts, at various angles and rotations as illustrated in Figure 1, any evidence of electrical continuity shall be noted. The test is then repeated

29、 on a set of connectors with the free connector fitted with male contacts and the fixed connector fitted with female contacts.

The connectors shall be subjected to the test 4a, voltage proof test, in accordance with IEC 60512-2 60512-4-1 1)at the specified test voltage. The voltage shall be applied between each group of contacts, one group consisting of all conta

31、cts in the free connector connected together, the second with all the contacts in the fixed connector connected together. 5 Requirements 5.1 Method A During the attempted mismating, there shall be no evidence of electrical continuity between the housing (metal shell) and the male contacts. 5.2 Metho

32、d B No breakdown or flashover shall be observed. 6 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) preparation of the specimen including details of the wiring; b) test voltage for method B; c) any deviation from the standar
