Claims
- 1. 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.
- 2. 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.
- 3. 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.degree. and offset by approximately 90.degree. before insertion of the locking element.
- 4. A connector as claimed in claim 1, wherein said spring locking arms on the housing are offset by approximately 90.degree. with respect to said connecting limb.
- 5. 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.
- 6. 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.
- 7. 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.
- 8. 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.
- 9. 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.
- 10. 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.
- 11. 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.
- 12. A connector as claimed in claim 8, wherein the upper housing part has at least one opening adjacent the locking element.
- 13. 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.
