Connector for watertight connection

1. A connector for mating with a counter-connector, the connector comprising:

a sleeve defining a recess and adapted to receive the counter-connector at least partially, an inner surface of the sleeve being essentially smooth, the recess bounded by the inner surface of the sleeve and a base of the recess formed by a base side of a housing, the recess open to a mating direction of the connector;

one or more contact pins located in the recess and extending along the mating direction of the connector; and

a securing element located in the recess away from the inner surface of the sleeve and surrounded by the recess, the securing element:

extending from the base of the recess along the mating direction;

having first and second opposing ends, the first end attached to the base of the recess, the second end defining a notch facing the mating direction, the notch configured to engage a respective means of the counter-connector for preserving a shape of the securing element;

including inner and outer side walls that connect the first and second opposing ends, the inner side wall facing the one or more contact pins, the outer side wall facing away from the one or more contact pins and toward the inner surface of the sleeve, the outer side wall located entirely away from the inner surface of the sleeve; and

comprising securing means for securing the connector to the counter-connector.

2. The connector of claim 1 , wherein the sleeve extends farther along the mating direction of the connector than the one or more contact pins or the securing element.

3. The connector of claim 1 , wherein the one or more contact pins are encompassed by the securing element at least partially, and wherein the securing element extends farther than the one or more contact pins along the mating direction of the connector.

4. The connector of claim 1 , wherein a length of the one or more contact pins is in a range of 3.4-6.4 mm.

5. The connector of claim 1 , wherein the securing element has an essentially U-shaped cross section with two elongated members extending along the mating direction, and wherein the one or more contact pins are provided between the two elongated members of the securing element.

6. The connector of claim 1 , wherein the securing means comprise a first undercut adapted to secure the connector to the counter-connector, wherein the first undercut is located on the outer side wall of the securing element.

7. The connector of claim 6 , wherein the securing means comprise a second undercut adapted to secure the connector to the counter-connector, wherein the second undercut is located at a different position on the outer side wall of the securing element along the mating direction than the first undercut.

8. The connector of claim 1 , wherein the connector comprises a coded surface at the base of the recess, the coded surface being adapted to receive torques applied to the counter-connector when connected to the connector.

9. The connector of claim 8 , wherein the coded surface comprises one or more stepped portions.

10. A system comprising:

a connector comprising:

a sleeve defining a recess and adapted to receive a counter-connector at least partially, an inner surface of the sleeve being essentially smooth, the recess defined by the inner surface of the sleeve and a base of the recess formed by a base side of a housing of the connector;

one or more contact pins located in the recess and extending along a mating direction of the connector, the one or more contact pins adapted to mate with one or more mating contacts on the counter-connector; and

a securing element located in the recess entirely away from the inner surface of the sleeve effective to enable the connector to receive the counter-connector in the recess between the securing element and the inner surface of the sleeve, the securing element extending from the base of the recess along the mating direction, the securing element having a side wall facing away from the one or more pins and toward the inner surface of the sleeve such that the securing element is surrounded by the recess, the securing element having a tip that defines a notch facing the mating direction, the notch configured to engage a respective means of the counter-connector for preserving a shape of the securing element, the securing element comprising securing means for securing the connector to the counter-connector; and

sealing means provided in the recess at the inner surface of the sleeve for providing a watertight seal between the sleeve of the connector and a body of the counter-connector when the connector is mated with the counter-connector.

11. The system of claim 10 , wherein:

the one or more contact pins are encompassed by the securing element at least partially; and

the securing element extends farther than the one or more contact pins along the mating direction of the connector.

12. The system of claim 10 , wherein:

the securing element has an essentially U-shaped cross section with two elongated members extending along the mating direction; and

the one or more contact pins are provided between the two elongated members of the securing element.

13. The system of claim 12 , wherein the securing means further comprise a first undercut located on at least one of the two elongated members and adapted to secure the connector to the counter-connector.

14. The system of claim 13 , wherein the first undercut is located on the side wall of the securing means that faces the inner surface of the sleeve.

15. The system of claim 13 , wherein:

the securing means further comprise a second undercut adapted to secure the connector to the counter-connector; and

the second undercut is located on the at least one of the two elongated members and at a different position along the mating direction than the first undercut.

16. The system of claim 15 , wherein the first undercut is closer to a base of the recess than the second undercut.

17. The system of claim 15 , wherein the first undercut and the second undercut are each located on the side wall that faces away from the one or more contact pins and toward the inner surface of the sleeve of the connector.

18. The system of claim 10 , wherein:

the connector further comprises a coded surface at a base of the recess; and

the coded surface is adapted to receive torque forces applied to the counter-connector when connected to the connector.

19. The system of claim 18 , wherein the coded surface comprises one or more stepped portions.

20. The system of claim 19 , wherein:

the one or more stepped portions include at least first and second stepped portions adapted to define an orientation of the connector relative to the counter-connector when connected to the connector;

the first stepped portion having a first height; and

the second stepped portion having a second height that is different than the first height of the first stepped portion.
