Checking gauge for checking the position of a shorting bridge in a connector

The present concept relates to a checking gauge for checking the position

of a shorting bridge arranged inside of a Safety Restraint System connector (such as an SRS connector). SRS connectors are well known in the art, so that it is refrained herein from giving a detailed explanation thereof.

The checking gauge is in particular suitable for the automotive area. For example, in the field of SRS modules, commonly a shorting bridge comprising two contact tongues is provided as a safety means inside of the SRS connector socket, respectively inside of the retainer arranged inside of the SRS connector socket. The shorting bridge short-circuits the

15

ignition contact pins of the SRS device, so that the SRS module does not unintentionally ignite due to e.g. electrical potential differences. During and after mating with the corresponding SRS connector (i.e. the counter connector) the contact pins are still short-circuited, so that the connection process is safe for the operator. After the mating is complete,

an additional member, usually a so-called CPA (connector position assurance) member, is manually inserted or pushed into the SRS connector. Then the CPA bends the contact tongues of the shorting bridge out of contact with the contact pins, thereby releasing the short circuit, so that the SRS device is ready for use.

25

To this end, it is important that the additional member, as e.g. the CPA member safely releases the short-circuiting and that the tongues of the shorting bridge are sufficiently remote from the ignition contact pins. If the tongues are not sufficiently remote from the pins, it might happen

30

that the tongues contact from time to time the pins due to e.g. vibration, thereby establishing an undesired short circuit.

Although the different parts (i.e. connector, retainer, shorting bridge etc.) are manufactured to make sure that this does not happen, in

practice due to production tolerances some parts inevitably fall out of the specification. To detect these faulty parts, the present concept suggests a checking gauge for checking the correct position. By means of the checking gauge it is possible to detect whether in installed condition of the additional member, i.e. the CPA, the shorting bridge is sufficiently

moved or bent away from the ignition contact pins.

To this end the checking gauge is shaped in form of a "test-member" or "test-CPA", which is slightly smaller than the actual additional member, respectively the CPA. The idea is that in case that the smaller test-CPA

sufficiently releases the shorting bridge from...
