Testing of crimped electric connections in on-board DC harness of spacecraft for determination of their properties

Some performances have been obtained as the result of testing of crimped electrical connections. On the basis of test results performance calculate transient electrical resistance of the new type of electric connection items implemented in on-board DC harness of modern spacecrafts. The causes of appearance of transient resistance in actual designs of crimped connection items were taken into account. The calculation results are compared to the transient resistance measurements. It is proposed to use the obtained data when building a model of crimped electrical connections ageing, applicable to new design solutions.
