Abstract

This connector can be connected to a counterpart connector having a counterpart contact, and is provided with an electric current sensor function. Specifically, the connector is provided with a contact, a protective member composed of an insulating material, a core, and an electric current detection member. The contact extends along the longitudinal direction so as to have a longitudinal part that can be connected to the counterpart contact. The protective member surrounds the contact in the plane orthogonal to the longitudinal direction. The core surrounds the protective member in the plane orthogonal to the longitudinal direction. The core has a gap. The electric current detection member is at least partially disposed within the gap.

Claims

1. A connector connectable with a mating connector having a mating contact, the connector having a current sensor function and comprising:

a contact extending along a front-rear direction to have a front end portion which is connectable to the mating contact;

a protection member made of an insulating material, the protection member surrounding the contact in a plane perpendicular to the front-rear direction;

a core having a gap and surrounding the protection member in a plane perpendicular to the front-rear direction; and

a current detection member arranged, at least in part, within the gap.

2. The connector as recited in claim 1, wherein:

the connector further comprises a holder formed with a holding hole;

the core and the current detection member are held in the holding hole;

the contact pierces the holding hole along the front-rear direction; and

the protection member is received in the holding hole.

3. The connector as recited in claim 2, wherein the holder has a rectangular shape in a plane perpendicular to the front-rear direction.

4. The connector as recited in claim 2, wherein:

the connector further comprises a housing made of a metal; and

the housing holds the holder.

5. The connector as recited in claim 1, wherein the protection member protrudes rearward beyond the core in the front-rear direction.

6. The connector as recited in claim 1, wherein the contact has a rear end portion which is formed with a screw.

7. The connector as recited in claim 6, wherein:

the contact is provided with a first regulation portion which is configured to regulate a rotation of the contact around an axis in parallel to the front-rear direction; and

the first regulation portion is located forward of a part of the contact where the screw is formed.

8. The connector as recited in claim 7, wherein the connector further comprises a portion which regulates a rotation of the first regulation portion.

9. The connector as recited in claim 1, wherein:

the connector further comprises an insulator; and

the protection member is a part of the insulator.

10. The connector as recited in claim 9, wherein the insulator extends forward from the protection member to surround the contact in a plane perpendicular to the front-rear direction.

11. The connector as recited in claim 9, wherein the insulator is provided with a second regulation portion which is configured to regulate a rotation of the insulator around an axis in parallel to the front-rear direction.

12. The connector as recited in claim 11, wherein the connector further comprises a portion which regulates a rotation of the second regulation portion.

13. The connector as recited in claim 1, wherein the contact is a pin contact.

14. The connector as recited in claim 1, wherein the contact is a socket contact.

15. A connector assembly comprising two or more of the connectors as recited in claim 1, a housing made of a metal and a holder, wherein:

the holder is held by the housing;

the holder is formed with a plurality of holding holes which correspond to the contacts, respectively;

the core and the current detection member of each of the connectors are held in the corresponding one of the holding holes;

the contact of each of the connectors pierces the corresponding one of the holding holes along the front-rear direction; and

the protection member of each of the connectors is received in the corresponding one of the holding holes.
