Equipment Overview
This device is a special test instrument used to detect whether the
force required to pull the plug out of the socket and the force
required to insert the plug into the socket are within the
specified range. It is an indispensable device for electrical
accessories, household appliance manufacturers, quality inspection
departments and scientific research institutions to detect daily
electrical appliances.
Structural features:
This device mainly consists of charging load test and plug-in force
test devices. The pull-out force device consists of the
installation fixture and the clamping device below, the main
weight, additional weights, and test plugs and sockets; the
insertion force device consists of the main weight, additional
weights, mounting seats, and test plugs and sockets. Based on the
experience, the pull clamp is changed to a counterweight, the
weight hook is directly connected to the test plug, a clamp is
configured to hold the sample, and a lift is used to lift the
weight or the main weight of the insertion force to avoid the
inconvenience of manual transportation. , improve work efficiency
and reduce labor costs,
Technical Parameters
1. The charging load test should meet the requirements.
The total mass of the test power supply plug or test vehicle plug,
clamping device, load-bearing device, main weight, and additional
weights shall exert a pull-out force that complies with the
provisions of Table 1. The mass of the additional weight should be
such that it exerts a force equal to one-tenth of the pullout
force. Hang the main weight on the test plug without shaking, and
then drop the additional weight onto the main weight from a height
of 5cm.
| Rated current or continuous maximum operating current | Force |
| AC, DC | 6＜I≤40 | 165 |
| 40＜I≤80 | 300 |
| AC | 80＜I≤150 | 440 |
| 150＜I≤250 | 660 |
| DC | I>80 | 750 |
| When the test object is an AC power supply socket or a vehicle
socket, the test load is 300N; when the test object is a DC vehicle
socket, the test load is 750N. |
Chart 1 Gravity load with different rated currents
Weight selection
According to chart 1, select an appropriate weight according to the
current and conduct the test. For example 165N=148.5+16.5
300N=270+30
440N=396+44
660N=396+44+154+66
750N=396+154+44+66+15+75
Among them, 148.5N, 270N, and 396N are the main weights with hooks.
The shape and size are as shown in the attached picture.
Shown in SN1013C-10. 16.5N, 30N, 44N, 154N, 66N, 15N, 75
The shape and size of additional weights with through holes are
shown in the attached figure SN1013C-13. Other size weights
The code can be customized later.
2. The charging plug pull-out force test should meet the
requirements.
Before testing, wipe off the oil on the pin. Pull out the test
power supply plug or test vehicle plug insertion box from the power
supply socket or out of the socket for 10 cycles. Then clamp it on
the fixture with a plug and do the test again. The charging plug
does not need to move at a uniform speed when pulling out or
plugging in, and the insertion force and pullout force are equal to
the gravity of the weight and the plug and are vertically downward.
3. Test standard plug
The test plug shall consist of finely ground contacts made of
hardened steel with a surface roughness not exceeding 0.8 μm over
its working length and spaced at a nominal distance with a
tolerance of ±0.5 mm. For other types of pins, The dimensions of
the pins or the distance between the surfaces of the pins shall
comply with the minimum dimensions given by the relevant standards.
