IEC 62196-1 Vehicle Connectors Withdrawal Force Latching Device Test Apparatus
Product information:
This test equipment conforms to IEC 62196-1:2020 clause 14.1.5, 14.1.6, fig13, fig14, IEC 62196-1:2014 clause 17.2. It is used to check the maximum force required when the test plug is withdrawn from the socket-outlet or vehicle connector and the minimum force required when the single-stage pin is pulled out of the socket. It is also used to verify the design of contact tubes can ensure adequate contact continuity before and after a number of operations corresponding to their operational life.
Maximum withdrawal force test:
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:
Table 1
| Sample type (AC A) | Withdrawal N | Principal weight N | Supplementary weight N |
| 6-40 | 165 | 148.5 | 16.5 |
| 41-80 | 300 | 270 | 30 |
| 81-150 | 440 | 396 | 44 |
| 151-250 | 660 | 396+148.5+49.5 | 66 |
| Sample type (DC A) | | | |
| Any | 750 | 396+148.5+49.5+15 | 75 |
| Clause 17.2 A | | | |
| <59 | 150 | 135 | 15 |
| 60-99 | 275 | 247.5 | 27.5 |
| 100-125 | 400 | 270+90 | 40 |
| Note: The principal weight already contains the test plug and hook weight |
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.
Table 2
| Nominal pin diameter mm | Diameter of gauge mm +0 -0.01 | Minimum total force N |
| 5 | 4.80 | 2.5 |
| 6 | 5.80 | 5 |
| 7 | 6.80 | 5 |
| 8 | 7.80 | 10 |
| 10 | 9.80 | 15 |
| 12 | 11.80 | 20 |
| Note: The minimum withdrawal force already includes the weight of the gauge |
Verification of the latching device:
The switched socket-outlet or vehicle connector with interlock is fixed to the support of an apparatus so that the axis of separation is horizontal. With the latching devices holding the plug into the socket-outlet or vehicle connector in the engaged position, an axial pull is applied to the cable attached at an appropriate plug inserted in the switched socket-outlet or vehicle connector with interlock.
