1 Scope

This part of GB/T 17737 applies to coaxial communication cables. It specifies the test method for determining the compression resistance of a coaxial cable.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this document. For undated references, the latest version (including all amendments) applies to this document.

bles-Part 1.Generic specification-General,definitionsandrequirements)

3 Terms and definitions

The terms and definitions defined by IEC 61196-1 apply to this document.

4 test methods

4.1 Test device

The test device enables the cable to be tested to be pressed between a flat steel base plate and a movable steel plate and applied to a 100 mm long test cable

The force should be uniform.

The edge of the movable plate should be rounded with a radius of 5mm. The rounded edges are not contained within the 100mm flat section. Suitable test

The device is shown in Figure 1.

4.2 Samples

The sample should be of sufficient length for the specified test.

Except as otherwise specified in relevant sub-standards or detailed specifications, the test temperature of the tested cable shall be maintained at 15°C~35°C.

For cables with an outside diameter of less than 5mm, the tested cable can be tested in a loop. In this case, the applied force is the specified value

Twice. The radius of the ring should be large enough to not affect the transmission characteristics of the cable.

4.3 Procedures

The cable under test shall be mounted on the base plate of the test device to prevent lateral sliding. Use a rounded parallel plate to move on the test

Apply a pressure load on the cable. The load should be applied gradually or stepwise to the value (F) specified in the relevant sub-specification or detail specification. There should be no

Sudden change. The maximum load should last 2min. After removing the load, the cable under test can be restored for 2 minutes. If step loading, step load ratio

Should not exceed 1.5.1.
