Abstract
The invention concerns a contact safety device for pin-and-socket connectors with an inserted state and a preassembled state, in which a safety mechanism is provided in the contact safety device to secure ignition contacts of the primer against interference and that safety mechanism comes into contact with a shorting bar in such a way that when/after the shorting bar is separated, the safety mechanism automatically goes into operation.
Claims13
A contact safety device for electrical pin-and-socket connectors with an inserted state and a preassembled state, which is suited for use between a primer for airbags and a control device of a motor vehicle, said contact safety device comprising:
- an isolating ring;
- a shorting bar integrated into the isolating ring configured to short out contact springs of the primer when the pin-and-socket connector is in the preassembled state, whereby the shorting bar contains two separate conducting elements relating to each other, each conducting element having a corresponding circuit element, the circuit elements cooperating in a contact position and separated spaced position, whereby at least one of the circuit elements is designed in such a way that the circuit elements change from the contact position to the separated position when the pin-and-socket connector attains its inserted state;
- and
- a contact safety member against interference, which contacts the two separate conducting elements at least in the inserted state, so that the two separate conducting elements are connected only by the contact safety member,
- the separate conducting elements being designed as protective contact springs, whereby each of the protective contact springs contact the contact springs of the primer with their protective contact spring ends, and the contact safety member produces a working connection between the protective contact springs.
A contact safety device for electrical pin-and-socket connectors with an inserted state and a preassembled state, which is suited for use between a primer for airbags and a control device of a motor vehicle, said contact safety device comprising:
- an isolating ring;
- a shorting bar integrated into the isolating ring configured to short out contact springs of the primer when the pin-and-socket connector is in the preassembled state, whereby the shorting bar contains two separate conducting elements relating to each other, the separate conducting elements being essentially mirror symmetric to each other, each conducting element having a corresponding circuit element, the circuit elements cooperating in a contact position and separated spaced position, whereby at least one of the circuit elements is designed in such a way that the circuit elements change from the contact position to the separated position when the pin-and-socket connector attains its inserted state;
- and
- a contact safety member against interference, which contacts the two separate conducting elements at least in the inserted state, so that the two separate conducting elements are connected only by the contact safety member.

- a contact safety member against interference, which contacts the two separate conducting elements at least in the inserted state, so that the two separate conducting elements are connected only by the contact safety member;
- and
- the separate conducting elements are each shaped as a U and in each case a first contact arm thereof is brought on at a right angle to the contact springs of the primer, and second arms of each conducting element are in contact with the contact safety member.

- and
- a contact safety member against interference, which permanently contacts the two separate conducting elements at least in the inserted state, so that the two separate conducting elements are connected only by the contact safety member.
