Locking electrical connector

1. An electrical connector of elongate shape, which comprises:

a main body having a first end region which comprises one or more electrical contacts in use for contact with a complementary connector component and a second end region opposite said first end region and from which depends a protective guide through which, in use, a flexible conductor extends, said main body of the connector comprising a locking mechanism to enable the connector to be selectively releasably secured to a complementary connector component, and the connector comprising a release control operable to act on the locking mechanism and allow release of the connector from the complementary connector component,

wherein said release control comprises a handle operable at a position further from the first end region of the connector than said second end as considered in the direction of the length of the connector, and

the handle is supported relative to the protective guide by being connected to or formed integrally with the release control and, additional to said support provided by the release control, is supported by means of at least one formation which contacts the protective guide of the connector.

2. An electrical connector of elongate shape, which comprises:

a main body;

a first end region of the main body, which comprises one or more electrical contacts and

a second end region of the main body opposite said first end region and from which depends a protective guide through which, in use, a flexible conductor extends;

a locking mechanism of the main body, said locking mechanism enabling the connector to be selectively releasably secured to a complementary connector component; and

a release control operable to act on the locking mechanism and allow release of the connector from the complementary connector component,

wherein said release control comprises a handle operable at a position further from the first end region of the connector than said second end as considered in the direction of the length of the connector,

the handle is supported relative to the protective guide by being connected to or formed integrally with the release control and, additional to said support provided by the release control, is supported by means of at least one formation which contacts the protective guide of the connector, and

said at least one formation serves, in use, to guide the handle to move in a direction substantially parallel with the length direction of the elongate connector.

3. An electrical connector of elongate shape, which comprises:

a main body;

a first end region of the main body, which comprises one or more electrical contacts and

a second end region of the main body opposite said first end region and from which depends a protective guide through which, in use, a flexible conductor extends;

a locking mechanism of the main body, said locking mechanism enabling the connector to be selectively releasably secured to a complementary connector component; and

a release control operable to act on the locking mechanism and allow release of the connector from the complementary connector component,

wherein said release control comprises a handle operable at a position further from the first end region of the connector than said second end as considered in the direction of the length of the connector,

the handle is supported relative to the protective guide by being connected to or formed integrally with the release control and, additional to said support provided by the release control, is supported by means of at least one formation which contacts either the main body or the protective guide of the connector,

said at least one formation serves, in use, to guide the handle to move in a direction substantially parallel with the length direction of the elongate connector, and

the main body or protective guide comprises two opposite side faces each formed with one of a groove or groove engaging projection which co-operates with a respective one of two groove or groove engaging formations of the handle thereby, in use, to assist in supporting and guiding movement of the handle.

4. The connector according to claim 3 wherein the release control is operable from a position aligned with said protective guide as considered in the length direction of the connector.

5. The connector according to claim 3 wherein the handle is integral with the release control.

6. The connector according to claim 3 wherein the release control is moveable in the length direction of the connector between a first, locking position and a second, release position.

7. The connector according to claim 3 and comprising bias means whereby the release control normally resides in a first, locking position but on application of force applied to the handle in a lengthwise direction of the connector, in a direction from the first to the second end region of the connector, effects movement of the release control to the second, release position.

8. The connector according to claim 3 wherein the handle is of a cross-sectional shape no larger than the maximum cross-sectional shape of the main body, as considered in the length direction of the connector.

9. The connector according to claim 3 wherein the handle is of an open, tubular shape which extends around the protective guide.

10. The connector according to claim 3 wherein the handle is of a skeleton like form.

11. The connector according to claim 3 wherein the protective guide is semi-flexible as compared with the rigidity of the main body.

12. The connector according to claim 3 wherein the handle is spaced from the protective guide whereby in use it does not inhibit flexibility of the guide.

13. The connector according to claim 3 wherein said at least one formation serves, in use, to guide the handle to move in a direction substantially parallel with the length direction of the elongate connector.

14. The connector according to claim 3 wherein the main body or protective guide comprises two opposite side faces each formed with one of a groove or groove engaging projection which co-operates with a respective one of two groove or groove engaging formations of the handle thereby, in use, to assist in supporting and guiding movement of the handle.

15. The connector according claim 3 wherein the locking mechanism is positioned within the main body of the connector and the release control connects to the locking mechanism from a position at the surface of the main body.

16. The connector according to claim 15 wherein the release control connects to the locking mechanism from a position at the surface of the main body which is close to the second end region of the main body.

17. The connector according to claim 3 wherein the handle comprises at least one finger grip position.

18. The connector according to claim 17 wherein the handle comprises two pairs of oppositely positioned finger grip positions.

19. The connector according to claim 3 wherein the handle comprises four side faces at least one of which is apertured or comprises a recess to provide a finger grip position.

20. The connector according to claim 19 wherein each of the four side faces is apertured or comprises a recess to provide a finger grip position.
