Abstract

An electrical connector includes a female connector removably connectable with a male connector. The female connector includes an outer ring shield, and first and second ring insulator. The first ring insulator is spaced inwardly of the outer ring shield to define a first recess with a first female electrical contact provided in the first recess. The second ring insulator is spaced inwardly of the first ring insulator to define a second recess with a second female electrical contact provided in the second recess. The male connector includes first and second. When the male and female connectors are electrically connected, the first and second male electrical contacts are received in the first and second recesses respectively.

Claims

1. An electrical connector comprising:

a) a female connector comprising;

i) an outer ring shield, wherein the outer ring shield comprises an outer ring shield outer surface and an outer ring shield inner surface that are both free of electrical contacts;

ii) a first ring insulator spaced inwardly of the outer ring shield to define a first recess between the outer ring shield and the first ring insulator with a first female connector electrical contact provided in the first recess;

iii) a second ring insulator spaced inwardly of the first ring insulator to define a second recess between the first and second ring insulators with a second female connector electrical contact provided in the second recess, and,

b) a male connector removably connectable with the female connector, the male connector comprising at least one first male connector electrical contact and at least one second male connector electrical contact,

wherein when the male and female connectors are electrically connected together, the first male connector electrical contact is received in the first recess and the second male connector electrical contact is received in the second recess, and

wherein the first ring insulator has a first ring insulator outer surface, and the first female connector electrical contact is a sleeve contact that at least substantially lines the first ring insulator outer surface.

2. The electrical connector of claim 1, wherein the second ring insulator has an inner cavity defining a third recess with a third female connector electrical contact provided in the third recess and the male connector comprises at least one third male connector electrical contact, wherein when the male and female connectors are electrically connected together, the third male connector electrical contact is received in the third recess.

3. The electrical connector of claim 2, wherein the second ring insulator has a second ring insulator inner surface, and the third female connector electrical contact is a sleeve contact that at least substantially lines the second ring insulator inner surface.

4. The electrical connector of claim 2, wherein the third male connector electrical contact is a pin contact.

5. The electrical connector of claim 2, wherein the third female connector electrical contact is a pin contact.

6. The electrical connector of claim 2, wherein the third male connector electrical contact is a sleeve contact.

7. The electrical connector of claim 2, wherein the male connector further comprises a body having the first, second and third male connector electrical contacts provided at one end and one of a plug or a socket provided at a longitudinally spaced apart second end of the body.

8. The electrical connector of claim 7, wherein the plug or socket is an AC plug or socket comprising a hot contact, a neutral contact, and a ground contact, and each contact is electrically connected to a different one of the first, second and third male connector electrical contacts respectively.

9. The electrical connector of claim 2, wherein the female connector further comprises a body having the outer ring shield and the first and second ring insulators provided at one end and one of a plug or a socket provided at a longitudinally spaced apart second end of the body.

10. The electrical connector of claim 9, wherein the plug or socket is an AC plug or socket comprising a hot contact, a neutral contact, and a ground contact, and each contact is electrically connected to a different one of the first, second and third female connector electrical contacts respectively.

11. The electrical connector of claim 9, wherein the male connector further comprises a male body having the first, second and third male connector electrical contacts provided at one end and the other of a plug or a socket provided at a longitudinally spaced apart second end of the male body.

12. The electrical connector of claim 2, wherein the first female connector electrical contact comprises a ground.

13. The electrical connector of claim 1, wherein the first and second ring recesses are concentric annular recesses.

14. The electrical connector of claim 1, wherein the first ring insulator has a first ring insulator inner surface, the second ring insulator has a second ring insulator outer surface, and the second female connector electrical contact is a sleeve contact that at least substantially lines at least one of the first ring insulator inner surface and the first ring insulator outer surface.

15. The electrical connector of claim 1, wherein the male and female connectors are secured together by a press fit.

16. The electrical connector of claim 1, wherein the male connector comprises a male connector outer ring shield that surrounds the first and second male connector electrical contacts, wherein the male connector outer ring shield has an outer surface that is free of electrical contacts.

17. An electrical connector comprising:

a) a female connector comprising;

i) an outer ring shield, wherein the outer ring shield comprises an outer ring shield outer surface and an outer ring shield inner surface that are both free of electrical contacts;

ii) a first ring insulator spaced inwardly of the outer ring shield to define a first recess between the outer ring shield and the first ring insulator with a first female connector electrical contact provided in the first recess;

iii) a second ring insulator spaced inwardly of the first ring insulator to define a second recess between the first and second ring insulators with a second female connector electrical contact provided in the second recess, and,

b) a male connector removably connectable with the female connector, the male connector comprising at least one first male connector electrical contact and at least one second male connector electrical contact,

wherein when the male and female connectors are electrically connected together, the first male connector electrical contact is received in the first recess and the second male connector electrical contact is received in the second recess,

wherein the male connector comprises a male connector outer ring shield that surrounds the first and second male connector electrical contacts, wherein the male connector outer ring shield has an outer surface that is free of electrical contacts, and

wherein the male connector outer ring shield is received in the first recess when the male and female connectors are electrically connected together.
