Abstract
Abstract The invention concerns an electrical connector, in particular for use between a socket (46) and an electrical control device, for inflatable restraining systems in motor vehicles. The connector has a housing (10,12) for accommodating electrical cables (28), as well as contact springs (24) connected to said cables, the contact springs serving to accommodate contact pins (50) of the associated socket with priming cap (trigger device); spring locking arms (42a,b) on the housing for attaching the housing to the socket; and a locking element (16) which, after insertion in a corresponding housing opening (56), secures the locking arms against unintentional release and in the locking position releases a short-circuiting link (52) between the contact pins of the socket, the locking arms being coupled to flexible housing sections (38a,b) in the direction of movement of the locking arms.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
198 words
In an electrical connector, comprising: a housing for accommodating electrical cables and contact springs connected to the cables, the contact springs being arranged to engage contact pins of an associated socket when the housing is attached to the socket; spring locking arms on the housing for attaching the housing to the socket, said spring locking arms being arranged to flex is a first direction which enables them to pass into the socket during attachment of the housing to the socket; a locking element which, after insertion in a corresponding housing opening, secures the locking arms against unintentional release and, in a locking position, releases a short-circuiting link between the contact pins of the socket, the improvement wherein the locking element has a U-shape, the U-shape including locking element arms and a connecting limb, the two locking element arms being positioned adjacent the spring locking arms so as to prevent movement of the spring locking arms when in the locked position, and the connecting limb being positioned between the short-circuiting link and the contacts when the locking element is in the locked position to release the short-circuiting link after insertion of the locking element into the corresponding housing opening.
Claim 2
Dependent Claim
198 words
In an electrical connector, comprising: a housing for accommodating electrical cables and contact springs connected to the cables, the contact springs being arranged to engage contact pins of an associated socket when the housing is attached to the socket; spring locking arms on the housing for attaching the housing to the socket, said spring locking arms being arranged to flex is a first direction which enables them to pass into the socket during attachment of the housing to the socket; a locking element which, after insertion in a corresponding housing opening, secures the locking arms against unintentional release and, in a locking position, releases a short-circuiting link between the contact pins of the socket, the improvement wherein the locking element has a U-shape, the U-shape including locking element arms and a connecting limb, the two locking element arms being positioned adjacent the spring locking arms so as to prevent movement of the spring locking arms when in the locked position, and the connecting limb being positioned between the short-circuiting link and the contacts when the locking element is in the locked position to release the short-circuiting link after insertion of the locking element into the corresponding housing opening.
Claim 3
Dependent Claim
45 words
A connector as claimed in claim 1, wherein said locking element has at least one outwardly-protruding enlargement at a free end section of the connecting limb for engaging a corresponding section of the short-circuiting link, said enlargement being arranged to extend between said contact pins.
Claim 4
Dependent Claim
58 words
A connector as claimed in claim 1, wherein said short-circuiting link consists of a leaf spring, said leaf spring having one end fixedly secured in an insulating ring of the socket and a free end which interconnects the contact pins after being bent back by approximately 180° and offset by approximately 90° before insertion of the locking element.
Claim 5
Dependent Claim
26 words
A connector as claimed in claim 1, wherein said spring locking arms on the housing are offset by approximately 90° with respect to said connecting limb.
Claim 6
Dependent Claim
44 words
A connector as claimed in claim 1, where the spring locking arms depend from housing sections which are arranged to flex in said first direction to assist the spring locking arms to pass into the socket during attachment of the housing to the socket.
Claim 7
Dependent Claim
77 words
A connector as claimed in claim 5, wherein said flexible housing sections are in the form of arms, said arms having end regions connected to a remainder of said housing at corresponding end regions only such that portions of said arms are unconnected to the remainder of the housing and therefore free to move in said first direction relative to the remainder of the housing as said locking arms are inserted into said opening in said socket.
Claim 8
Dependent Claim
33 words
A connector as claimed in claim 6, wherein said arms have two ends and are connected by said end regions to a remainder of said housing at one of said two ends only.
Claim 9
Dependent Claim
27 words
A connector as claimed in claim 5, wherein said flexible housing sections extend on two sides of the housing and extend generally parallel to the electrical cables.
Claim 10
Dependent Claim
76 words
A connector as claimed in claim 1, wherein the housing comprises first, second, and third housing parts: a lower first housing part to accommodate the contact springs, an upper second housing part to cover the lower housing part and to localize the electrical cables between the upper and lower housing part, and a locking element that can be led through a corresponding opening in the upper housing part, said locking element being the third housing part.
Claim 11
Dependent Claim
35 words
A connector as claimed in claim 8, wherein the upper housing part, the locking element, or both the upper housing part and the locking element are connected to the lower housing part via flexible straps.
Claim 12
Dependent Claim
35 words
A connector as claimed in claim 8, wherein the upper housing part has a projecting section protruding toward the lower housing part and engaging an upper end of the contacts springs in an assembled position.
Claim 13
Dependent Claim
21 words
A connector as claimed in claim 8, wherein the upper housing part has at least one opening adjacent the locking element.
Claim 14
Dependent Claim
32 words
A connector as claimed in claim 8, wherein the lower first housing part is a nozzle and has at least one radially-projecting web for engagement in a correspond slot in the socket.
