28、OMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-51: Examinations and measurements Pin gauge withdrawal force for rectangular ferrule multi-fibre connectors 1 Scope This part of IEC 61300 is intended to describe the procedure required to measure the pin gauge withdrawal force for rectangular f
29、errule multi-fibre connectors. This measurement can be used as an alternative to the measurement of the pin gauge insertion force, both of which evaluate the fit of the pin gauge(s) into the guide pin hole(s) of the female-type connector. The experimental verification of interchangeability between t
30、hem is shown in Annex A. For the male-type connector, IEC 61300-3-49 is applied to evaluate how securely the guide pins are retained in the guide holes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appl

35、ement method is applied for optical connectors specified in IEC 61754-5, IEC 61754-7-1, IEC 61754-7-2, IEC 61754-10 and IEC 61754-18. Two methods using weights or a tensile testing machine are described in this standard. The optical connector is held using a fixture. For the measurement for a single
36、 guide pin hole, the pin gauge is placed in a pin gauge chuck and the weight or the tensile testing machine is connected to the pin gauge chuck. For the measurement for two guide pin holes, the plug gauge is placed in a plug gauge chuck and the weight or the tensile testing machine is connected to t
37、he plug gauge chuck. By using the plug gauge, it is possible to check not only the size of each guide pin hole but also the relative position and the relative angle between two guide pin holes. 3.2 Test conditions For a precise measurement such as design verification, the test conditions shall be co
38、ntrolled accurately as required in Table 1. Table 1 Test conditions Temperature C Relative humidity % RH 22,0 24,0 50,0 10,0 4 Apparatus 4.1 Fixture The measurement shall not be affected by the connector fixture. The position and direction of the connector during the test shall not change as the tes
39、t is repeated. The connector shall be placed in the fixture so that the front face of the connector housing is retained by the fixture as shown in Figure 3 and Figure 4. 4.2 Pin gauge chuck The pin gauge chuck shall have a pin gauge retention force much greater than the required connector pin gauge
40、withdrawal force, typically more than 200 N when using a tensile testing machine. The connection of the pin gauge to the weight or the tensile testing machine chuck shall not affect the measurement. 4.3 Plug gauge chuck The plug gauge chuck shall have a plug gauge retention force much greater than t
41、he required connector plug gauge withdrawal force, typically more than 200 N, when using a tensile testing machine. The connection of the plug gauge to the weight or the tensile testing machine chuck shall not affect the measurement. 4.4 Pin gauge Figure 1 and Table 2 show the pin gauge and dimensio
42、ns of the pin gauge. The pin gauge shall have the required dimensions as specified in IEC 61754-5.

The weight measurement is used for pass/fail tests including final inspection. 4.7 Tensile testing machine The tensile testing machine sh
46、all be able to record (and/or hold) the maximum value during the measurement. The tensile testing machine measurement is used for design verification testing. 5 Procedure 5.1 Method A: Method using the weight (Figure 3) The following steps shall be taken: a) Prepare the device under test (DUT) accor
47、ding to the manufacturers instructions and check the appearance in accordance with IEC 61300-3-1. b) Place the DUT in the fixture. c) Place the pin gauge or the plug gauge in the chuck. d) Insert the pin gauge or the plug gauge into the guide pin hole(s) of the connector by more than 5,5 mm. e) Fix
48、the weight to the chuck. Adjust the total weight of the jig and the weight to the specified value. f) Apply the weight slowly. Be sure that the force is applied along the axis of the guide pin hole(s). g) Wait for the specified duration. Record if the pin gauge or the plug gauge is withdrawn by the
49、specified force. Unless otherwise specified, the maximum duration shall be 15 s.
