Abstract

The present invention relates to squib connectors, for instance for airbag ignition systems, which allow the electrical or electronic monitoring of the correct coupling of a squib plug connector with its corresponding counterpart. According to the invention, a squib connector has at least two terminals having corresponding signal lines. In order to allow an electrical monitoring of the correct coupling of the plug connector, the terminals are in electrical contact with each other in the uncoupled or incorrectly coupled condition of the plug connector. This electrical contact between the terminals is configured to be separated upon correct coupling to a corresponding counter-connector either automatically or by an actuating action. The disconnecting of the terminals may then be monitored by any suitable monitoring means.

Claims (22)

1. A connector for a safety restraint system, comprising:

a plug connector;

at least two terminals assigned to the plug connector having corresponding signal lines, wherein the at least two terminals are in electrical contact with each other in the uncoupled or incorrectly coupled condition of the plug connector in order to allow an electrical monitoring of the correct coupling of the plug connector; and

a connector position assurance member which is insertable into the plug connector and which upon full-insertion into the plug connector separates contact between the at least two terminals, wherein the electrical contact between the at least two terminals is established by a contact means which is provided in form of two bendable contact tongues, each tongue associated with one of the at least two terminals and being oriented essentially in plug-in direction, whereby the two contact tongues are arranged in an x-shape orientation with respect to each other and contacting each other in the uncoupled or incorrectly coupled condition of the plug connector, so that due to an x-shaped orientation of the two contact tongues upon moving the free ends of the two contact tongues towards each other the two contact tongues are moved out of contact with each other.

2. The connector according to claim 1 , wherein the electrical contact between the at least two terminals is configured so that it can be separated upon correct coupling to a corresponding counter-connector of the plug connector either automatically or by an actuating action.

3. The connector according to claim 2 , wherein the electrical contact between the at least two terminals is established by at least one contact means which in the uncoupled or incorrectly coupled condition of the plug connector is in a position to electrically connect the at least two terminals with each other and which can be disconnected from a connecting position upon correct coupling of the plug connector to the corresponding counter-connector.

4. The connector according to claim 2 , wherein the electrical contact between the at least two terminals is configured so that, upon correct coupling of the plug connector to a corresponding counter-connector, the contact between the at least two terminals is automatically separated due to a mechanical contact with a part of the counter-connector.

5. The connector according to claim 1 , wherein the electrical contact between the at least two terminals is established by at least one contact means which is provided in form of at least one bendable contact tongue, which bendable tongue is bend out of contact upon correct coupling of the plug connector to a corresponding counter-connector of the plug connector either automatically or by an actuating action.

6. The connector according to claim 1 , wherein the connector is used for an airbag ignition system.

7. The connector according to claim 2 , further comprising the counter-connector configured to cooperate with the plug connector.

8. The connector according to claim 7 , wherein the counter-connector does not comprise any shorting clip.

9. A connector for a safety restraint system, comprising:

a plug connector;

a connector position assurance member which is insertable into the plug connector and which upon full-insertion into the plug connector separates contact between the at least two terminals, wherein the electrical contact between the at least two terminals is established by a contact means which is provided in form of two bendable contact tongues being directed in plug-in direction, each tongue associated with one of the at least two terminals and at least one of the two contact tongues is provided with an S-shaped portion, the two contact tongues having each a contact portion being parallel to the respective other contact portion and a contact protrusion on at least one of said contact portions, said contact protrusion provides an electrical contact with the respective other contact portion, the connector further comprising the connector position assurance member which is insertable into the plug connector and which upon insertion into the plug connector comes into contact with the S-shaped portion and bends the contact protrusion out of contact with the respective other contact portion, thereby separating the electrical contact between the at least two terminals.

10. The connector according to claim 9 , wherein the electrical contact between the at least two terminals is configured so that it can be separated upon correct coupling to a corresponding counter-connector of the plug connector either automatically or by an actuating action.

11. The connector according to claim 10 , wherein the electrical contact between the at least two terminals is established by at least one contact means which in the uncoupled or incorrectly coupled condition of the plug connector is in a position to electrically connect the at least two terminals with each other and which can be disconnected from a connecting position upon correct coupling of the plug connector to the corresponding counter-connector.

12. The connector according to claim 10 , wherein the electrical contact between the at least two terminals is configured so that, upon correct coupling of the plug connector to a corresponding counter-connector, the contact between the at least two terminals is automatically separated due to a mechanical contact with a part of the counter-connector.

13. The connector according to claim 9 , wherein the electrical contact between the at least two terminals is established by at least one contact means which is provided in form of at least one bendable contact tongue, which bendable tongue is bend out of contact upon correct coupling of the plug connector to a corresponding counter-connector of the plug connector either automatically or by an actuating action.

14. The connector according to claim 9 , wherein the connector is used for an airbag ignition system.

15. The connector according to claim 10 , further comprising the counter-connector configured to cooperate with the plug connector.

16. The connector according to claim 15 , wherein the counter-connector does not comprise any shorting clip.
