12、age 1 (From EIA Standards Proposal No. 3990, formulated under the cognizance EIA CE-2.0 Committee on National Connector Standards.) 1 Introduction 1.1 Scope This standard establishes a test method to assess the ability of a component to withstand stresses caused by repeated insertion and extraction
13、of contacts during maintenance. This test procedure applies only to connector assemblies containing removable contacts and is to be used where a connector is to be stressed in the area of contact retention and conductor sealing. 2 Test resources 2.1 Equipment 2.1.1 Test equipment shall consist ofthe
14、 insertion and removal tools specified. 2.1.2 A force gage of suitable range for the force being measured, so that the reading shall lie in the middle 50 percent of the scale, where practicable, with a nominal accuracy of 2 percent. 3 Test specimen 3.1 Description A test specimen shall consist of a
15、connector with all contacts installed and wired according to the referencing document. 3.2 Preparation All rear hardware or accessories should be loosened or removed to permit extraction and insertion of contacts. The accessories shall remain loose or removed during the test. EIA-364-24B Page2 4 Tes
16、t procedure 4.1 Unless otherwise specified, select 20% ofthe contacts, but no fewer than six, at random from each specimen for test. For connectors having six or fewer contacts, all contacts shall be used for the test. At least one contact shall be in or near the center of the connector. Unless othe
17、rwise specified, there shall be ten extraction and insertion cycles for each contact. The force required to insert and remove each contact in and from the connector shall be measured during the initial and final maintenance aging cycle in accordance with EIA-364-05. 4 .1.1 Record the following initi
18、al measurements, if specified 4 .1.1.1 Contact retention force. 4 .1.1.2 Contact insertion and extraction force. 4 .1.2 Record the following final measurements, if specified 4 .1.2.1 Contact retention force. 4.1.2.2 Contact insertion and extraction force. 4.1.2.3 Visual examination for damage to wir
19、e seals, etc. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Design or type of insertion and extraction tools see 2.1.1 5.2 Test specimen preparation see 3.1 5.3 Number of test cycles, if other than 1 0 see 4.1 5.4 Number of samples to be tested 5
