IEC 60320-1 Figure 2 Device For Checking Non-Solid Pins For Plug
Pins Testing VDE Type
Product information:
The appliance is checked by the test of IEC60884-1:2022 clause
14.2, figure 17, for pins which are not solid, by the following
test which is made after the test of clause 21. A force of 100 N is
exerted on the pin, which is supported as shown in IEC60884-1,
IEC60884-1, figure 14, for 1 min in a direction perpendicular to
the axis of the pin, by means of a steel rod having a diameter of
4,8 mm, the axis of which is also perpendicular to the axis of the
pin. During the application of the force, the reduction of the
dimension of the pin at the point where the force is applied shall
not exceed 0,15 mm. After removal of the rod, the dimensions of the
pin shall not have changed by more than 0,06 mm in any direction.
Features:
When it comes to checking non-solid pins, such as hollow or tubular
pins, a specialized device known as a pin gauge or pin micrometer
can be used. A pin gauge is a precision measuring instrument
designed to verify the diameter and dimensional accuracy of
non-solid pins. Here's an overview of how a pin gauge works and its
key features:
Design and Construction: A pin gauge consists of a set of
cylindrical pins, each with a specific diameter. These pins are
typically made of hardened steel and are arranged in a stepped or
progressive order. The pins are securely held in a handle or
holder, which provides stability during the measurement process.
Diameter Ranges: Pin gauges are available in various diameter
ranges to accommodate different pin sizes. Each pin in the set has
a specific diameter, which is typically marked on the pin or its
holder for easy identification.
Measurement Process: To check the diameter of a non-solid pin, the
appropriate pin gauge is selected based on the expected pin size.
The pin is inserted into the hollow or tubular section of the pin
being measured. The operator then assesses the fit of the pin gauge
in the pin. If the pin gauge slides in smoothly without any
noticeable play or excessive resistance, it indicates that the
pin's diameter matches the diameter of the pin gauge.
Accuracy and Tolerance: Pin gauges are manufactured with high
precision to ensure accurate measurements. They are typically
calibrated to known standards and have a specified tolerance, which
indicates the acceptable range of variation in the measured
diameter.
Application: Pin gauges are commonly used in industries such as
manufacturing, engineering, and quality control to verify the
dimensions of non-solid pins. They are especially useful for
checking the compliance of pins used in various applications, such
as fasteners, connectors, and precision instruments.
It is important to handle pin gauges with care to avoid damage to
the pins or the measuring surfaces. Regular calibration and
maintenance of pin gauges are crucial to ensure their accuracy and
reliability.
Technical parameters:
| No.: | Specifications |
| Load weight | 100N |
| Steel rod | Φ4.8mm |
| Time for force application | 1 minute |
| Equipment material | Stainless steel |
Operation Steps:
1. Before using it for the first time, the operator needs to be
familiar with the relevant standards in order to use the test
device more effectively and correctly and complete the test.
2. Put the plug and pin on the bracket according to the standard
requirements, and then use the handle to lifting the weight. At
this time, apply a pressure of 100N to the plug. After 1 minute,
lower the lifting device and release the weight pressure. The
direction of force is against the central axis of the pin, and the
force is applied to the central axis of the pin through a steel rod
of Φ4.8mm.
3. During the force application, the size of the position where the
pin is stressed may be reduced, but the reduction value cannot
exceed 0.15mm.
4. After the steel rod is removed, the dimensions of the pins
should not change by more than 0.06mm.
