Connectors for electronic equipment - Tests and measurements - Part 16-18: Mechanical tests on contacts and terminations - Test 16r: Deflection of contacts, simulation

IEC 60512-16-18:2008 details a standard test method to measure the deflection of a simulated contact in its cavity or housing. Although this test method is intended for cylindrical male contacts, and is particularly applicable to those where the contacts fit into an insert, which may have some elasticity, its use for contacts with other geometries and housing details, is not excluded.

Connecteurs pour équipements électroniques - Essais et mesures - Partie 16-18: Essais mécaniques des contacts et des sorties - Essai 16r: Débattement des contacts, simulation

La CEI 60512-16-18:2008 détaille une méthode d'essai normalisée pour mesurer le débattement d'un contact simulé dans son alvéole ou son capot. Bien que cette méthode d'essai soit destinée à des contacts mâles cylindriques et soit particulièrement applicable à ceux où les contacts s'adaptent dans un isolant, qui peut avoir une certaine élasticité, son utilisation pour des contacts avec d'autres géométries et détails de capot n'est pas exclue.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60512-16-18 has been prepared by subcommittee 48B:

Connectors, of IEC technical committee 48: Electromechanical components and mechanical

structures for electronic equipment.

This standard cancels and replaces test 16r of IEC 60512-8, issued in 1993. This standard is

to be read in conjunction with IEC 60512-1 and IEC 60512-1-100 which explains the structure

of the IEC 60512 series.

Part 16-18: Mechanical tests on contacts and terminations –
Test 16r: Deflection of contacts, simulation
1 Scope and object

This part of IEC 60512, when required by the detail specification, is used for testing

electomechanical components within the scope of technical committee 48. It may also be

used for similar devices when specified in a detail specification.

The object of this part of IEC 60512 is to detail a standard test method to measure the

deflection of a simulated contact in its cavity or housing.

Although this test method is intended for cylindrical male contacts, and is particularly

applicable to those where the contacts fit into an insert, which may have some elasticity, its

use for contacts with other geometries and housing details, is not excluded. In which case,

the detail specification should contain sufficient detail, given under Clause 5, to enable the

test to be done.
2 Normative references

The following referenced documents are indispensable for the application of this document.

For dated references, only the edition cited applies. For undated references, the latest edition

of the referenced document (including any amendments) applies.

IEC 60512-1-1, Connectors for electronic equipment – Tests and measurements – Part 1-1:

General examination – Test 1a: Visual examination
3 Preparations
3.1 Preparation of specimen

The specimen shall consist of a housing, with an insert or other contact-receiving connector

body or device. Any preconditioning given in the component detail specification shall be

applied. Five such specimens shall be prepared.
3.2 Equipment

A test pin (gauge pin) shall be provided, the design of which shall replicate those parts of the

contact normally fitted into the cavity that have relevance to this test.

A universal testing machine suitable for the test procedure detailed in Clause 4 shall be

required, equipped with all relevant test fixtures needed to hold the specimen under test.

3.3 Mounting

If mounting of the specimen is appropriate, it shall be as specified in the component detail

specification.
The specimen shall not be mated to its corresponding, or other, component.

or housing. For inserts or housings having 3 or less cavities, all shall be tested. A specified

force shall be applied in a manner as, or similar to, that shown in Figure 1 (which is an

example). The force shall be applied a
