Abstract

A socket contact is connectable with a first terminal and a second terminal at opposite ends thereof in an axial direction, respectively. The socket contact comprises a first portion, a second portion and a coupling portion. The first portion has a first end, a second end and a first spring portion. The first end includes a first contact point which is to be connected to the first terminal. The second end includes a second contact point which is to be connected to the second terminal. The first spring portion is positioned between the first contact point and the second contact point. The second portion has a third end, a fourth end and a second spring portion. The third end includes a third contact point which is to be connected to the first terminal. The fourth end includes a fourth contact point which is to be connected to the second terminal. The second spring portion is positioned between the third contact point and the fourth contact point. The coupling portion couples the first end with the fourth end.

First claim

What is claimed is:

1 . A socket contact connectable with a first terminal and a second terminal at opposite ends thereof in an axial direction, respectively, the socket contact comprising:
a first portion having a first end, a second end and a first spring portion, the first end including a first contact point which is to be connected to the first terminal, the second end including a second contact point which is to be connected to the second terminal, the first spring portion being positioned between the first contact point and the second contact point; a second portion having a third end, a fourth end and a second spring portion, the third end including a third contact point which is to be connected to the first terminal, the fourth end including a fourth contact point which is to be connected to the second terminal, the second spring portion being positioned between the third contact point and the fourth contact point; and a coupling portion coupling the first end with the fourth end.

2 . The socket contact as recited in claim 1 , wherein each of the first spring portion and the second spring portion does not have a part which is folded back in the axial direction.

3 . The socket contact as recited in claim 1 , wherein the first portion and the second portion are arranged to face each other in a perpendicular direction perpendicular to the axial direction.

4 . The socket contact as recited in claim 3 , wherein the coupling portion has a Z-like shape when projected on a predetermined plane which is defined by the axial direction and the perpendicular direction.

5 . The socket contact as recited in claim 4 , wherein the coupling portion has a base portion which extends in a direction intersecting with the axial direction in a plane parallel to the predetermined plane.

6 . An inter-connector comprising the socket contact as recited in claim 1 and a holding member which accommodates, at least in part, the socket contact to hold it.

7 . The inter-connector as recited in claim 6 , wherein:
the socket contact is formed with a lance which extends from the first end toward a side of the second end; an abutment portion is formed inside of the holding member; the lance has an end in the axial direction; and the abutment portion faces the end of the lance in the axial direction.

8 . The inter-connector as recited in claim 7 , wherein each of the first portion and the second portion is positioned between the lance and the coupling portion.

9 . The inter-connector as recited in claim 7 , wherein:
the socket contact has a first shoulder portion and a second shoulder portion; the first shoulder portion is formed on a first boundary portion between the first end and the coupling portion; the second shoulder portion is formed on a second boundary portion between the first end and the lance; the holding member is formed with a first receiving portion and a second receiving portion which are positioned inside of the holding member and are able to receive the first shoulder portion and the second shoulder portion in the axial direction, respectively; and when the first shoulder portion and the second shoulder portion are brought into contact with the first receiving portion and the second receiving portion, respectively, the end of the lance is positioned away from the abutment portion in the axial direction so that the socket contact is movable in the axial direction within the holding member.

10 . A connector device comprising the inter-connector as recited in claim 6 , a first connector and a second connector, wherein;
the first connector comprises the first terminal and a first outer conductor; the first terminal functions as a first center conductor; the first outer conductor is positioned away from the first center conductor in a radial direction perpendicular the axial direction; the second connector comprises the second terminal and a second outer conductor; the second terminal functions as a second center conductor; the second outer conductor is positioned away from the second center conductor in the radial direction; the inter-connector is to be mated with the first connector and the second connector at opposite ends thereof in the axial direction, respectively; the inter-connector further comprises an outer contact; the holding member insulates the socket contact and the outer contact from each other; the outer contact has an outer first end, an outer second end and an outer main portion; the outer first end and the outer second end are positioned away from each other in the axial direction; the outer first end and the outer second end are to be connected with the first outer conductor and the second outer conductor, respectively; the outer main portion couples the outer first end with the outer second end; the outer contact is formed with a plurality of first slits and a plurality of second slits; each of the first slits extends from the outer first end toward the outer second end while not reaching the outer second end; each of the second slits extends from the outer second end toward the outer first end while not reaching the outer first end; the first slits and the second slits are alternately arranged in a circumferential direction around the axial direction; the first slits are positioned at first positions, respectively, in the axial direction; the second slits are positioned at second positions, respectively, in the axial direction; and each of the first positions and each of the second positions overlap with each other.

11 . The connector device as recited in claim 10 , wherein the first slits is equal in number to the second slits.

12 . The connector device as recited in claim 10 , wherein:
the outer contact is provided with a first stopper and a second stopper; the first stopper is positioned between the first slits and the outer second end; the second stopper is positioned between the second slits and the outer first end; the holding member is formed with at least one first protrusion and at least one second protrusion; the at least one first protrusion is received in at least one of the first slits; the at least one second protrusion is received in at least one of the second slits; the first protrusion has a first facing surface which faces the first stopper in the axial direction; and the second protrusion has a second facing surface which faces the second stopper in the axial direction.

13 . The connector device as recited in claim 12 , wherein:
the first protrusion further has a first slope which obliquely intersects with the axial direction; the first facing surface is positioned between the first slope and the first stopper in the axial direction; the second protrusion further has a second slope which obliquely intersects with the axial direction; and the second facing surface is positioned between the second slope and the second stopper in the axial direction.

14 . The connector device as recited in claim 12 , wherein:
only the second outer conductor among the first outer conductor and the second outer conductor is formed with a lock portion which locks the outer second end; the lock portion locks the outer second end so that the inter-connector is held by the second connector; and when the first connector is removed from the inter-connector, the second stopper and the second facing surface are brought into abutment with each other so that the holding member is prevented from being removed from the outer contact.

15 . The connector device as recited in claim 10 , wherein the outer main portion of the out
