5 Description

5.1 Materials/Features

The relay base assembly consists of:

 socket body: the material shall be a thermoplast, non-flammable, according to EN 2349-100 and this specification;

 sealing rubber: the material shall be silicon rubber, non-flammable, according to EN 2349-100 and this specification The sealing rubber shall seal wires with external diameters as shown in the product standard;

 crimp contacts: in accordance with EN 3155-017 The crimp contacts shall be selected to accommodate cables as defined in 4.3 The finish of the crimp contacts shall be: gold-plated — Thickness: 1,27 µm min

5.2 Interface seal

The relay and base interface shall be sealed by a silicon rubber The rubber prevents any environmental influence such as fluids between:

 relay and base;

 base and wiring

The rubber shall provide an additional electrical isolation between relay terminals and housing

The hardness of the rubber shall not cause any damage or mechanical deformations when tightening the relay

on its base

The silicon rubber shall be a part of the plug-in relays in accordance with EN 2548-001

5.3 Polarizing holes

5.3.1 Two-pole bases

The relay bases shall be provided with polarizing holes to accept the polarizing pins used on the two-pole relays only The shape of the polarizing holes shall accept the polarizing pins used on the 28 V d.c and

115 V a.c coil relays of EN 2548-001

The purpose of the polarizing pins and holes is to prevent installation of 28 V d.c or 115 V a.c coil relays into the non-mating relay base

The polarizing pin shall ensure the correct installation of the relay to its base

5.3.2 Four-pole bases

The keying of the four-pole d.c and a.c coil relay bases shall be provided by different coil terminal positions They shall also ensure installation of relay on its base in one position only

On a four-pole version this fool proofing shall be ensured by the contact pins position

6 Definition drawings and mass

For the dimensions and mechanical characteristics, reference is made to the product standards

7 Qualification tests

The relay bases shall meet the applicable requirements of EN 2349-100 as shown in Table 1 The qualification test shall be performed together with the mating relay

The test samples shall be series production units, selected by random from a batch All test results shall be recorded

8.2.2 Test sequence

The qualification test samples shall be in accordance with Table 5, considering the requirements as per Table 1

In case one sample fails to meet the requirements, it shall be replaced by a new test sample and the whole test sequence related to the failed unit to be repeated

In case two or more samples fail to meet the requirement, the qualification test is to be suspended The qualification authority shall be informed accordingly

The failed units shall be investigated and the necessary corrective actions introduced

The complete qualification program has to be repeated with modified test samples
