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.
Note: The adjustable clamp is adopted, which can be switched
vertically and horizontally, and can clamp various products; the D
clamp is replaced by a ring, which is more convenient to operate
and use; the main weight is directly counterweighted without a
bracket.
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:
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 |

| <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 |
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.
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 |
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
