Definitions
- the present invention relates to an electrical connector can be used in particular in a device pyrotechnic ignition of a protective airbag a driver or passenger of a motor vehicle.
- one of the privileged contact pins 3 (ground pin) has a length higher than that of other contact pins 3.
- the longer spindle 3 reaches first on body of housing 1 and establishes the first connection electric with corresponding socket element 4 the housing 1, the length of this element forming a socket being of course also greater than the length of the other elements forming a socket 4.
- the housing comprising the elements forming sockets comprises a front part, of preferably beak-shaped, allowing to lift simultaneously the flexible fingers except that associated with the preferred pin to disengage them from their respective pins when the pin finger privileged is in contact with the element forming the socket corresponding.
- the housing comprising the elements forming sockets is arranged to disengage the prominent shape of the element forming a socket and interrupting the electrical connection temporary between the preferred spindle and the element forming a socket when the two housings are one position at which the pins come into contact electric with their elements forming sockets correspondents.
- the two housings include guide means mutual when plugged in and, preferably, these means comprise a part forming a slide integrated into one of the cases and a piece forming a slide secured to the other housing.
- the electrical connector advantageously applies to pyrotechnic ignition devices for the inflatable protective bags occupants of a motor vehicle.
- Figure 1 shows a longitudinal sectional view an electrical connector of the prior art, the two boxes are separated from each other.
- FIG. 2 represents a view in longitudinal section of the electrical connector of the invention, both of which housings are separated from each other.
- Figure 3 is a sectional view along line III-III in Figure 2.
- Figure 4 is a sectional view along line IV-IV in Figure 2.
- Figure 5 is a sectional view similar to that of the Figure 3, but showing the two boxes of the connector in fully depressed position one in the other.
- Figure 6 is a sectional view similar to that of the Figure 4, but representing the two boxes of the connector in fully depressed position one in the other.
- Figure 7 is a sectional view along line VII-VII in Figure 2.
- the connector electric includes two boxes 1, 2 in material insulating, pluggable into each other so that pins 3, of the same length, housed parallel in the case 2, engage in electrical contact respectively in elements forming sockets 4 housed in the housing 1 so as to make connections electrical or phases in which can circulate relatively large currents.
- the electrical connector can be applied to ensure the supply of a pyrotechnic igniter for bags vehicle protection airbags automobiles, but it is understood that it can apply to any other device to be powered by particularly large currents.
- the contact pins 3 are electrically connected to conducting wires 5, while the elements forming sockets are connected to conductive wires 6.
- the electrical connector has three pairs of pins 3 and elements forming sockets 4, of which one located below in relation to Figure 2 constitutes a so-called “privileged” phase, in particular mass, to protect staff against charges electrostatic when handling the connector.
- the electrical connector comprises in addition to arranged means of early connection to ensure an electrical connection first preferably the preferred pin 3 to the corresponding socket element 4 and then interrupt the temporary electrical connection when all pins 3 come into electrical contact with their respective socket elements 4.
- a shunt comprising several flexible conductive fingers 7, in this case at number of three, housed in the pin holder 2 and interconnected by a common conductive strip 8 extending transversely to pins 3 and integral of a part of the internal wall of the housing 2 delimiting the receiving opening of the housing 1.
- Each finger flexible 7 has a convex front part 7a starting from the conductive strip 8 and ending in a convex free end 7b held elastically in contact on a corresponding pin 3 when the pin holder 2 is separated from case 1 as shown in Figures 3 and 4.
- Figure 3 shows that the front part 7a of finger 7 associated with the pin privileged 3 is more strongly convex than the parts anterior of the other fingers so as to form a prominent part that can come directly into contact with the corresponding socket member 4 before pins 3 are in contact with their elements forming respective sockets during operation for plugging in the two boxes 1, 2.
- the housing 1 has a front part in the shape of a beak the made at the end of the upper wall 1b secured of the housing 1 and delimiting with the lower wall 1c secured to this case the specific housing of the corresponding socket element 4.
- This part frontal 1a allows the fingers to be lifted simultaneously flexible 7, except the one associated with the preferred spindle 3, to disengage them from their respective pins 3 when the finger 7 of the preferred pin 3 is in contact with the corresponding socket element 4.
- the upper wall integral with the housing 1 delimiting the housing of the element forming a socket 4 associated with preferred pin 3 does not have upper front part as shown in figure 3 or, according to a variant, this upper front part is extremely small, so that the finger 7 associated with the preferred pin 3 maintains the electrical contact between this pin and the element forming corresponding socket over a distance predetermined insertion of the housing 1 into the housing 2.
- the upper walls 1b delimiting the housings of bushing elements 4 each include a lug 1d penetrating into an opening 4a of the forming element corresponding socket 4 so as to retain the latter in his home.
- the lower wall lc of each housing of a socket element 4 comprises a lug-shaped front part which, together with the the beak-shaped front, also allows the maintenance of the bushing element 4 in its housing.
- one 2 of the housings has a part forming slide 9 integrated in the housing 2 and in which can slide a piece forming a slide 10 secured to the housing 1.
- connection of the two boxes 1, 2 of the connector is carried out by inserting the housing 1 into the housing 2, whose relative movements are precisely guided by the part forming slide 10 and the part forming slide 9.
- the connection of the two boxes 1, 2 is first translated by establishing a first electrical contact between the prominent shape 7a of the finger 7 of the preferred pin 3 and the element forming the socket corresponding 4, this primary electrical connection thus ensuring immediately the flow of charges of static electricity.
- the front part la associated with each socket element 4 causes the lifting the corresponding flexible finger 7 so as to disengage its free end 7b from the spindle corresponding 3 and thus interrupt the connection electric with this pin.
- the electrical connector of the invention thus makes it possible to make a connection at the time of connection temporary on the phase to be connected first, then on all phases, the usual connections, ensuring thus effective protection of personnel performing connector connection.
