3.2.1.2 Test procedure

Put the standard gauge A on the outer contact of the connector once. This is a stable size operation and should only be used in the insulator from the connector

In the case of taking out.

Then, the standard gauge B is placed on the outer contact member in a vertical state. At this point, you should be able to maintain the standard. This test can also be taken out

Conducted on the connector of the insulator.

3.2.2.2 Test procedure

Insert the test standard gauge C into the center contact three times with an insertion depth of at least 3.17 mm (0.125 in). This is a stable size operation, and

It should only be done on the jack center contact that is removed from the connector.

Then, the standard gauge D is inserted into the center contact and kept in a vertical state. At this point, you should be able to maintain the standard. This test can also be

Performed on the connector without removing the center contact.

3.4 General requirements for module installation and panel mounting of connectors

3.4.1 Radial misalignment

Connector Insertion Radial misalignment refers to the coaxial deviation of the pin connector and the jack connector during the start of the insertion and the insertion process.

(See Figure 7).

Fixed mounting connectors and floating mounting connectors must not exceed 0.51 mm in radial misalignment at the beginning of the insertion.

Figure 7 Schematic diagram of radial misalignment of the connector

3.4.2 Axial misalignment

For fixed and floating mounting connectors, the total axial travel allowed for floating mounting is 1.52 mm (0.060 in). And

The installation plan should ensure that the axial travel is at least 0.25mm (0.010in) [better 0.76mm (0.030in)], ensuring that there is enough under working conditions.

The length of the insertion (see Figure 8).

4.1 General

The following clauses specify the recommended ratings, characteristics and test conditions to be considered when preparing a detailed specification (DS), as well as the phase

The minimum level of conformance testing, the blank detailed specification format, and the detailed specification development guidelines should be tested.

4.2 Ratings and characteristics (see Chapter 6 of GB/T 11313.1-2013)

The values specified in Table 7 are recommended for TMA type connectors and are for reference by the detail specifier. These values apply when the connector is finished

The condition when fully inserted.

Some of the tests listed do not give any recommended values and these tests are usually not required. When these tests are needed, they are formulated by the specification.

It is decided to fill in the applicable values in the detailed specification.
