Abstract

An electrical connection system comprises a first component carrying a pair of male connector elements releasably mated with a pair of female connector elements carried by a second connector component. A shorting clip is associated with the first component for providing an electrical short between the male connector elements. A safety latch is selectively receivable in a latch position for moving the shorting clip to a non-shorting position when the first component is mated with the second component and a lock element is arranged to be actuated by the safety latch to prevent separation of the first and second components while the safety latch is in the latch position.

Claims

1. An electrical connection including:

a) a first component carrying a first pair of electrical connector elements;

b) a second component releasably mated with the first component and carrying a second pair of electrical connector elements engaged with the first pair of electrical connector elements;

c) a shorting element for electrically shorting the first pair of electrical connector elements;

d) a safety latch element selectively receivable in a latch position for moving the shorting element to a non-shorting position when the second component is mated with the first component; and

,

e) lock means actuated by the safety latch element for preventing separation of the first and second components while the safety latch element is in the latch position.

2. An electrical connection as defined in claim 1 wherein the second component carries the lock means.

3. An electrical connection as defined in claim 2 wherein the lock means includes a lock element which is moved into locking engagement with the first component when the safety latch element is in its latch position.

4. An electrical connection as defined in claim 1 wherein the shorting element comprises a resilient clip which extends between the first pair of electrical connector elements.

5. An electrical connection as defined in claim 4 wherein the safety latch element includes means for engaging the shorting element when in said latch position and moving said shorting element out of contact with at least one of said first pair of electrical connector elements thereby electrically opening said first pair of connector elements.

6. An electrical connection as defined in claim 5 wherein the lock means includes a resilient element which is deflected into locking engagement by the safety latch element when the safety latch element is in latch position.

7. An electrical connection as defined in claim 6 wherein the resilient element extends from the second component and wherein the safety latch element when in the latch position extends through the first component.

8. An electrical connection as defined in claim 1 wherein the first component comprises a socket into which the second component extends.

9. An electrical connection as defined in claim 8 wherein the safety latch extends into the second component when in a latch position, and wherein the lock means includes a resilient element which is biased laterally into locking engagement with the socket when the safety latch is in the latch position.

10. An electrical connection including:

a) a first component carrying a male connector element;

b) a second component releasably mated with the first component and carrying a female connector element engaged with the male connector element;

c) a shorting element biased for electrically connecting the male connector element to a first electrical potential;

d) a safety latch element selectively positionable in a latch position when the second component is mated with the first component;

e) means on said safety latch element for selectively urging said shorting element against said bias and electrically disconnecting said male connector element from said first electrical potential when in said latch position; and

,

f) lock means actuated by the safety latch element for preventing separation of the first and second components while the safety latch element is in the latch position.

11. An electrical connection as defined in claim 10 wherein the second component carries the lock means.

12. An electrical connection as defined in claim 10 wherein the safety latch element includes tab portions that maintain portions of the second component in engagement with the first component.

13. An electrical connection as defined in claim 12 wherein the safety latch element extends into the second element when in the latch position.

14. An electrical connection as defined in claim 10 wherein the first component includes a socket which receives the first component.

15. An electrical connection as defined in claim 14 wherein the second component includes resilient first portions that engage in recesses formed in the socket.

16. An electrical connection as defined in claim 15 wherein the safety latch element when in the latch position prevents the resilient first portions from disengaging from the recesses in the socket.

17. An electrical connection including:

a) a first component carrying a first electrical connector element;

b) a second component releasably mounted with the first component and carrying a second electrical connector element engaged with the first electrical connector element;

c) a shorting element for electrically connecting the first electrical connector element to a first electrical potential;

d) a safety latch element selectively receivable in a latch position for moving the shorting element to disconnect the first electrical connector from the first electrical potential when the second component is mated with the first component; and

e) lock means actuated by the safety latch element for preventing separation of the first and second components while the safety latch is in the latch position.
