View Patent ↗An electrical connector including a housing having a socket shaped to at least partially receive a mating plug; a plurality of electrically conductive contact elements at least partially extending into said socket for effecting electrical connection with corresponding electrically conductive contacts of the plug; and a door element coupled to the housing, wherein the door element is mounted for slidable movement along a nonlinear path between an open position whereby the socket is laid open for engagement by the mating plug and a closed position whereby access to the socket is inhibited.
1. An electrical connector including:
(a) a housing having a socket shaped to at least partially receive a mating plug;
(b) a plurality of electrically conductive contact elements at least partially extending into said socket for effecting electrical connection with corresponding electrically conductive contacts of the plug; and
(c) a door element coupled to the housing,
wherein the door element is mounted for slidable movement along a nonlinear path between an open position whereby the socket is laid open for engagement by the mating plug and a closed position whereby access to the socket is inhibited;
wherein the door element includes guiding lugs for guiding the mating plug into the socket during insertion, wherein the guiding lugs include locking surfaces for engaging with a locking clip on the mating plug when the mating plug is inserted in the socket.
2. The electrical connector as claimed in claim 1 , wherein the door element includes a ledge to be used to effect translation of the door from the closed position to the open position.
3. The electrical connector as claimed in claim 1 , wherein the door element includes an instructional feature indicating a direction to apply a force to move the door element from the closed position to the open position.
4. The electrical connector as claimed in claim 1 , wherein an exterior side of the door element that first enters the socket is tapered.
5. The electrical connector as claimed in claim 1 , wherein the housing includes a removable insert to which the door element is coupled.
6. The electrical connector as claimed in claim 1 , wherein movement of the door element along the non-linear path from the closed position towards the open position is constrained and includes a component of movement in a direction transverse to an insertion direction of the plug into the socket and a component of movement in a direction aligned with the insertion direction.
7. The electrical connector as claimed in claim 6 , wherein during a first part of the movement of the door element along the nonlinear path from the closed position towards the open position, movement of the door element in the direction transverse to the insertion direction is greater than movement of the door element in the direction aligned with the insertion direction.
8. The electrical connector as claimed in claim 7 , wherein during a second part of the movement of the door element along the nonlinear path from the closed position towards the open position, movement of the door element in the direction transverse to the insertion direction is less than movement of the door element in the direction aligned with the insertion direction.
9. The electrical connector as claimed in claim 1 , wherein the nonlinear path is defined by two parallel guides formed in the housing.
10. The electrical connector as claimed in claim 9 , wherein the guides are slot-like and formed in opposed interior walls of the housing.
11. The electrical connector as claimed in claim 9 , further comprising two pairs of tracking lugs extending from opposite sides of the door element, each pair of tracking lugs being at least partially seated in a corresponding one of the guides.
12. The electrical connector as claimed in claim 11 , wherein the tracking lugs effect translation of the door element along the nonlinear path as the door element moves between the open position and the closed position.
13. The electrical connector as claimed in claim 9 , wherein the guides include first sections generally parallel to an insertion direction of the socket and second sections normal to the insertion direction.
14. The electrical connector as claimed in claim 13 , wherein the first sections of the guides are substantially parallel and at least partially arcuate, and the second sections of the guides are substantially parallel and at least partially arcuate.
15. The electrical connector as claimed in claim 1 , further including a resilient biasing means that applies a force tending to maintain the door element in the closed position.
16. The electrical connector claimed in claim 15 , wherein the resilient biasing means includes a torsion spring having a first leg substantially retained in the housing and a second leg substantially retained in the door element.
17. The electrical connector as claimed in claim 16 , wherein the torsion spring is one of two torsion springs, each having a first leg substantially retained in the housing and a second leg substantially retained in the door element, the springs being interconnected by a bridge portion.
18. The electrical connector as claimed in claim 17 , wherein the two torsion springs are formed as a single length of wire.
19. The electrical connector as claimed in claim 1 , wherein the door element is seated on a floor of the socket when arranged in the open position.
20. The electrical connector as claimed in claim 19 , wherein the door element is seated generally flat on the floor of the socket when arranged in the open position.
21. A door element for an electrical connector, including:
(a) a body defining a generally planar exterior surface for inhibiting access to a socket of the electrical connector;
(b) two pairs of tracking lugs extending from opposite sides of the body for at least partially extending into corresponding guides of the electrical connector; and
(c) guiding lugs arranged on an interior surface of the body,
wherein the tracking lugs facilitate translation of the door element to open the socket to receive a mating connector plug or to close the socket to inhibit access to the socket by said plug,
wherein the guiding lugs are configured to guide the mating plug into the socket during insertion, wherein the guiding lugs include locking surfaces for engaging with a locking clip on the mating plug when the mating plug is inserted.
22. The door element as claimed in claim 21 , wherein an exterior side of the door element that first enters the socket is tapered.
23. The door element as claimed in claim 21 , wherein the tracking lugs effect translation of the door element along a nonlinear path of the guides as the door element moves between an open position and a closed position.
24. The door element as claimed in claim 23 , further comprising a ledge to be used to effect translation of the door element from the closed position to the open position.
25. The door element claimed in claim 23 , wherein the door element is seated generally flat on a floor of the socket when arranged in the open position.
26. The door element as claimed in claim 23 , wherein the door element includes an instructional feature indicating a direction to apply a force to move the door element from the closed position to the open position.
27. An electrical connector including:
(a) a housing defining a socket configured to at least partially receive a mating plug;
(b) a plurality of electrically conductive contact elements at least partially extending into the socket for effecting electrical connection with corresponding electrically conductive contacts of the mating plug;
(c) a door element coupled to the housing, the door element being moveable relative to the housing along a nonlinear path between an open position and a closed position, wherein the socket is laid open for engagement with the mating plug when the door element is in the open position and wherein access to the socket is inhibited when the door element is in the closed position; and
(d) a torsion spring that applies a force biasing the door element to the closed position, the torsion spring having a first leg substantially retained in the housing and a second leg substantially retained in the door element.
28. The electrical connector as claimed in claim 27 , wherein the torsion spring is one of two torsion springs, each having a first leg substantially retained in the housing and a second leg substantially retained in the door element, the springs being interconnected by a bridge portion.
29. The electrical connector as claimed in claim 28 , wherein the two torsion springs are formed as a single length of wire.
