IEC62196 EV Switch Socket Interlock Withdraw Force Test Apparatus
Complied Standards & Clauses for Switch Socket Interlock Withdraw Force Test Apparatus
IEC 62196-1:2020 clause 14.1.5, 14.1.6, fig13, fig14. IEC 62196-1:2014 clause 17.2.
Equipment Overview for Switch Socket Interlock Withdraw Force Test Apparatus
Test purpose: The structure of the charging interface should allow the charging gun to be easily inserted and pulled out, and should prevent the charging gun from falling out of the socket during normal use. Verify that the maximum force required to pull the charging cable out of the appliance socket is within the range specified in the standard.
Test Principle: Maximum pull-out force of the socket: Apply the maximum pull-out force specified in the standard (the total force of the main weight, additional weight, hook (clamping device), and test plug) to the test plug, and the plug should come out of the socket.
Structure: This device is composed of the clamping device
installed under the top plate A, the main weight F, the additional
weight G and the test plug C. The device frame is compatible with
GB/T20234.1 Figure 5 and GB11918.4 Figure 102, including mechanical
load test of horizontal horizontal charging interface, locking
device test and insertion force test.
Technical Parameters for Switch Socket Interlock Withdraw Force Test Apparatus
A Maximum withdrawal force The maximum withdrawal force of the socket-outlet shall meet the requirements of Table 1. Apply the maximum withdrawal force specified in the standard (total force of the principal weight, supplementary weight, hook (clamping device) to the test plug, when the supplementary weight is dropped from a height of 50mm, the plug should come out of the socket. User should select an appropriate weight for the test according to the following table:
B Minimum withdrawal force Insert the gauge with the minimum withdrawal force specified in the standard (that is, the test pin (single pin) that meets the requirements of this standard, the total mass of the pin should be equal to the value specified in the table) into each individual socket in the socket-outlet. The gauge must not be removed from the socket within 30 seconds.
C Structure features This device is mainly composed of the installation fixture, the clamping device, principal weight, supplementary weight and the test plug. Based on experience, the pull clamp is changed to a counterweight, the weight hook is directly connected to the test plug, and the fixture for holding the sample is configured. The specific shape is shown in figure 1.
D Test plug The test plug, according to the relevant standard sheets, shall have finely ground contacts of hardened steel, having a surface roughness not exceeding 0,8 µm over their active length and spaced at the nominal distances, with a tolerance of ±0,05 mm. The dimension of the plug contacts or the distance between contact surfaces for other types of plug contacts shall be in accordance with the minimum dimension(s) given in the relevant standard sheets, with a tolerance of +0,010mm The test plugs are not included in this test apparatus, please use those test plugs that client already ordered separately as following:
E Test pins The test pins are not included in this test apparatus, please use those test pins that client already ordered separately as following:
