Abstract

An electric connector includes a first connector 2 and a second connector 22 . The first connector includes a first contact 4 , a second contact 6 , a plate like ground plate 8 arranged between the first and second contacts, and a first housing that holds the first contact, the second contact, and the ground plate. The second connector includes a third contact 30 connected to the first contact, a fourth contact 32 connected to the second contact, and a ground metal part arranged at both ends of the third and fourth contacts in a contact array direction and configured to be in contact with the ground plate, and a second housing that holds the third and fourth contacts and the ground metal part. The ground plate includes a projecting portion formed on both side surfaces in the contact array direction and come in contact with the ground metal part.

First claim

The invention claimed is:

1. An electric connector, comprising:
a first connector; and
a second connector, wherein
the first connector includes
a first contact,
a second contact,
a planar ground plate arranged between the first contact and the second contact, and
a first housing configured to hold the first contact, the second contact, and the ground plate,

the second connector includes
a third contact connected to the first contact,
a fourth contact connected to the second contact,
a ground metal part arranged on both ends of the third contact and the fourth contact in a contact array direction and configured to be in contact with the ground plate, and
a second housing configured to hold the third contact, the fourth contact, and the ground metal part,

wherein the ground plate includes a projecting portion formed on both side surfaces of the ground plate in the contact array direction and configured to be in contact with the ground metal part,
the ground metal part includes a coupling portion at a rear end of the ground metal part to couple a plurality of ground metal parts and a planar plate portion arranged between the third contact and the fourth contact,
wherein the plate portion extends from the coupling portion toward a first connector side and does not couple the ground metal parts, and
the ground metal part is configured to be in contact with a side surface of the projecting portion in the contact array direction.

2. The electric connector according to claim 1 , wherein the first connector or the second connector is able to be fitted upside down.

3. An electric connector configured to be a second connector to which a first connector is connected, wherein
the first connector includes
a first contact,
a second contact,
a planar ground plate arranged between the first contact and the second contact, and
a first housing configured to hold the first contact, the second contact, and the ground plate,

the second connector includes
a third contact connected to the first contact,
a fourth contact connected to the second contact,
a ground metal part arranged on both ends of the third contact and the fourth contact in a contact array direction and configured to be in contact with the ground plate, and
a second housing configured to hold the third contact, the fourth contact, and the ground metal part,

wherein the ground plate includes a projecting portion formed on both side surfaces of the ground plate in the contact array direction and configured to be in contact with the ground metal part,
the ground metal part includes a coupling portion at a rear end of the ground metal part to couple a plurality of ground metal parts and a planar plate portion arranged between the third contact and the fourth contact,
the plate portion extends from the coupling portion toward a first connector side and does not couple the ground metal parts, and
the ground metal part is configured to be in contact with a side surface of the projecting portion in the contact array direction.

4. The electric connector according to claim 3 , wherein
the first connector includes a first shell configured to cover the outer circumference of the first housing,
the second connector includes a second shell configured to cover the outer circumference of the second housing, and
the second shell includes a flexible contactor configured to be in contact with the inner wall of the first shell.

5. The electric connector according to claim 3 , wherein
the second housing is divided into a receiving unit, a third contact holding unit, and a fourth contact holding unit,
the receiving unit receiving a tip end of the third contact, a tip end of the fourth contact, and the ground metal part,
the third contact holding unit holding the third contact, and
the fourth contact holding unit holding the fourth contact.

6. An electric connector configured to be a first connector to which a second connector is connected, wherein
the first connector includes
a first contact,
a second contact different from the first contact,
a planar ground plate arranged between the first contact and the second contact, and
a first housing configured to hold the first contact, the second contact, and the ground plate,

the second connector includes
a third contact connected to the first contact,
a fourth contact connected to the second contact,
a ground metal part arranged on both ends of the third contact and the fourth contact in a contact array direction and configured to be in contact with the ground plate, and
a second housing configured to hold the third contact, the fourth contact, and the ground metal part,

wherein at least one of the first contact, the second contact, and the ground plate is formed by insert-molding,
within a fitting area in which the first connector fits to the second connector, the first connector includes an overlapping portion where the first contact and the second contact are overlapped vertically and a plurality of non-overlapping portions where the first contact and the second contact are not overlapped vertically,
the ground plate includes a projecting portion formed on both side surfaces of the ground plate in the contact array direction and configured to be in contact with the ground metal part, and
the ground metal part is configured to be in contact with a side surface of the projecting portion in the contact array direction.

7. The electric connector according to claim 6 , wherein the projecting portion includes
a locking portion configured to engage with a tip end of the ground metal part and prevent removal of the second connector from the first connector, and
a contact portion configured to be in contact with the tip end of the ground metal part.

8. The electric connector according to claim 6 , wherein
the projecting portion includes a locking portion configured to engage with a tip end of the ground metal part and prevent removal of the second connector from the first connector, and
the side surface of the projecting portion in the contact array direction is in contact with a portion of the ground metal part located away from the tip end of the ground metal part in a removal direction side of the second connector.

9. The electric connector according to claim 6 , wherein
the ground plate includes an opening through which a metal mold part protrudes during insert-molding at a position corresponding to at least one of the non-overlapping portions.
