the travel distance.
g) From the starting point of the displacement to the end point (7.5 mm 0.3 mm), then,
back to the starting point is one cycle (that is, one cycle is equal to two separate
bending and normalizing movements).

5.4 After normally inserting the direct plug-in equipment into the socket-outlet, use the steel
probe shown in Figure 10 of GB/T 2099.1-2021 to apply a force of 1 N to the root of the pin,
and use an electrical indicator with a voltage between 40 V ~ 50 V to display the contact status
of relevant components.
5.5 Use 3 new samples to carry out the roller drop test in 24.3 of GB/T 2099.1-2021 in
accordance with the normal use conditions. If the direct plug-in equipment is equipped with a
flexible cable, then, the free length of the flexible cable extending from the direct plug-in
equipment is approximately 100 mm.
The number of drops is:
---100 times: if the weight of the specimen without the flexible cable does not exceed 100
g;
---50 times: if the weight of the specimen without the flexible cable exceeds 100 g, but
does not exceed 200 g;

NOTE: as long as the contact gauge touches the live plug bush, it is deemed to satisfy the
requirements.
---the socket-outlet non-contact gauge shall not come into contact with the live plug bush
of the socket-outlet.
When using measuring gauges, if the socket-outlet has a protective door, it shall be disabled to
avoid affecting the test.
