12、gnizance EIA CE-2.0 Committee on National Connector Standards. 1 Introduction 1.1 Scope This test procedure establishes a test method to determine whether coupling pin strength can withstand external forces required to mate and unmated circular bayonet electrical connectors with gages or devices. 2
13、Test resources 2.1 Equipment 2.1.1 A steel test tip shall be used for application of the load on swaged pins. 2.1.2 A steel test fixture contoured to the shape of the coupling pin shall be used for application of the load on the weld or brazed pins. 3 Test specimens 3.1 Description Specimens shall b
14、e applicable to series I and II type circular connectors. When tested as specified in 4.1, bayonet coupling pins shall withstand a load of 50 pounds +5/-0 pounds without displacement or perceptible loosening of coupling pins. 3.1.1 Series I connectors General application within weapon system where a
15、 quick disconnect coupling system is required for blind mating or other mating problem areas. These connectors provide high-vibration characteristics and are suitable for Severe Wind And Moisture Problem (SWAMP) areas with proper connector accessories. 3.1.2 Series II connectors General application
16、within weapon systems which are not subjected to high vibration or (SWAMP) areas. EIA-364-57 Page 2 4 Test procedures 4.1 Load application One coupling pin in each receptacle shall be subjected to 50 pounds +5/-0 pounds load applied to the swaged end along the major axis of the coupling on swaged pi
17、ns, and perpendicular to the pin centerline on the exposed portion of welded or brazed pins. 4.1.1 Perform push-out / retention force test utilizing suitable equipment to verify the properly installed bayonet pin withstands a minimum of 50 pounds push-out force. 4.2 Pass/fail criteria 4.2.1 Microsco
18、pically inspect the surface below the bayonet pin head before and after push-out retention test using appropriate magnification. The head of the bayonet pin should remain flat, with no gaps between the bayonet pin head and the shell body. The bayonet pin head shall not be deformed in any way, and it
19、 shall be perpendicular to the shell body within 3 (not slanted to the side); see figure 1. There shall be no evidence of cracked or chipped plating (if plated) and no evidence of splitting of the staked pin on the staked surface. Figure 1 - Acceptance criteria 4.2.2 If any of these cited rejection
20、criteria are observed, do not proceed until problems have been corrected. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Part numbers 5.2 Pass/fail criteria 5.3 If applicable, connector assemblies to be included.
