Abstract

Apparatus and methods are described, including apparatus that includes a male-connector body comprising at least one mating surface, and shaped to define a hollow core. A plurality of electrically-conductive male-connector terminals are coupled to the mating surface of the male-connector body. A longitudinal insert is configured to, by moving inside the hollow core, push the male-connector terminals radially outward. Other embodiments are also described.

First claim

What is claimed is:

1. A method for establishing an electrical connection between a male connector and a female connector, comprising:
providing a male connector comprising a male connector body having a male mating surface comprising a plurality of electrically-conductive male-connector terminals and defining a hollow male connector core;
providing a longitudinal insert configured for inserting into the hollow male connector core;
providing a female connector configured to matingly receive the male-connector body and having a female mating surface comprising a plurality of electrically-conductive female-connector terminals defining a recess;
inserting the longitudinal insert at least partially into the male connector core;
second inserting the male connector body into the female connector, wherein each male-connector terminal is not in contact with a respective female-connector terminal; and
bringing each male-connector terminal into contact with a respective female-connector terminal.

2. The method of claim 1 , wherein the longitudinal insert has an insert surface defining an insert hollow core, and the female connector comprises a longitudinal protrusion disposed in the recess.

3. The method of claim 2 , wherein after second inserting at least a portion of a length of the longitudinal protrusion is seated in the insert core.

4. The method of claim 3 , wherein inserting comprises fully inserting the longitudinal insert into the male connector core.

5. The method of claim 1 , wherein the longitudinal insert has a shape complementary to a shape of the hollow male connector core.

6. The method of claim 1 , wherein the plurality of electrically-conductive male-connector terminals and the plurality of electrically-conductive female-connector terminals are arranged both longitudinally and circumferentially.

7. The method of claim 2 , wherein the longitudinal protrusion does not contact the female mating surface.

8. The method of claim 7 , wherein the longitudinal protrusion is not located at the transverse center of the female connector.

9. The method of claim 1 , wherein inserting comprises fully inserting the longitudinal insert into the male connector core.

10. The method of claim 9 , wherein the male connector has a polygonal cross-section and a substantially uniform diameter.

11. The method of claim 10 , wherein after second inserting the male connector is fully inserted into the female connector and there is a gap of at least 1 mm between each male-connector terminal and a respective female-connector terminal, and an entire length of the longitudinal protrusion is seated in the insert core.

12. The method of claim 11 , wherein bringing each male-connector terminal into contact with a respective female-connector terminal comprises rotating the longitudinal insert relative to the male connector body whereby the male-connector terminals are pushed radially outward such that each male-connector terminal is brought into contact with a respective female-connector terminal.

13. The method of claim 1 , wherein a diameter of a distal end of the male connector core is narrower than a diameter of a proximal end of the male connector core.

14. The method of claim 13 , wherein a diameter of a distal end of the longitudinal insert is narrower than a diameter of a proximal end of the longitudinal insert.

15. The method of claim 14 , wherein the longitudinal insert has a greater diameter relative to the male connector core.

16. The method of claim 15 , wherein inserting comprises partially inserting the longitudinal insert into the hollow male connector core.

17. The method of claim 16 , wherein second inserting comprises fully inserting the male connector into the female connector.

18. The method of claim 17 , wherein bringing each male-connector terminal into contact with a respective female-connector terminal comprises fully inserting the longitudinal insert into the male connector core such that an entire length of the longitudinal protrusion is seated in the insert core, whereby the male-connector terminals are pushed radially outward such that each male-connector terminal is brought into contact with a respective female-connector terminal.

19. A method for establishing an electrical connection between a male connector and a female connector, comprising:
providing a male connector comprising a plurality of electrically-conductive terminals in a first circumferential and longitudinal arrangement;
providing a female connector configured to matingly receive the male and comprising a plurality of electrically-conductive terminals in a second circumferential and longitudinal arrangement;
inserting the male connector into the female connector such that each of the electrically-conductive terminals of the male connector are not in contact with the electrically-conductive terminals of the female connector; and
bringing each electrically-conductive terminals of the male connector into contact with a one of the electrically-conductive terminals of the female-connector by pushing the electrically-conductive terminals of the male connector outwards without compressing the male connector.

20. A method for establishing an electrical connection between a male connector and a female connector, comprising:
arranging an electrically-insulative sheath between a male connector and female connector, said electrically-insulative sheath comprising a plurality of radially displaceable electrical conductors, said male connector comprising a plurality of electrically-conductive terminals in a first circumferential and longitudinal arrangement, said female connector comprising a plurality of electrically-conductive terminals in a second circumferential and longitudinal arrangement;
displacing the radially displaceable electrical conductors outwards by partially inserting the male connector into the female connector; and
bringing the radially displaceable electrical conductors into contact with the electrically-conductive terminals of the male connectors and the electrically-conductive terminals of the female connector by fully inserting the male connector into the female connector.
