Abstract

A connector includes plural terminals, a housing holding the terminals, and an inner shield. The connector is configured to be connected to a mating connector by moving toward the mating connector in a first direction relatively with respect to the mating connector. The terminals include two terminals arranged on both sides of the inner shield in a second direction perpendicular to the first direction. The inner shield includes a base extending in a third direction perpendicular to the first direction and the second direction, and an extension protruding from the base. The housing includes a shield holder holding the extension. This connector reduces noise propagation between the terminals.

First claim

What is claimed is:

1. A connector configured to be connected to a mating connector including a plurality of mating terminals, the connector comprising:
a plurality of terminals each configured to be electrically connected to a respective one of the plurality of mating terminals while the connector is connected to the mating connector;
a housing holding the plurality of terminals; and
an inner shield, wherein:
the connector is configured to be connected to the mating connector by moving toward the mating connector in a first direction relatively with respect to the mating connector,
the plurality of terminals include two terminals arranged on both sides of the inner shield in a second direction perpendicular to the first direction,
the housing includes:
a bottom wall having a surface directed in the first direction, the surface of the bottom wall facing a hollow space;
a peripheral wall protruding in the first direction from the surface of the bottom wall and surrounding the hollow space; and
a wall portion protruding in the first direction from the surface of the bottom wall and disposed in the hollow space,

the inner shield includes:
a base extending in a third direction which is perpendicular to the first direction and is different from the second direction; and
a first extension, a second extension and a third extension, which protrude in the first direction from the base to the hollow space, and

the wall portion of the housing includes:
a shield holder holding the first extension;
a first accommodation portion accommodating the second extension therein; and
a second accommodation portion accommodating the third extension therein.

2. The connector of claim 1 , wherein:
the shield holder of the wall portion of the housing includes a third accommodation portion accommodating the first extension therein, and
the first extension is held by the wall portion such that the first extension contacts the wall portion and faces the wall portion in the third direction at the third accommodation portion of the shield holder of the housing.

3. The connector of claim 1 , wherein:
the mating connector further includes a mating inner shield, and
the inner shield further includes a contacting portion configured to contact the mating inner shield of the mating connector.

4. The connector of claim 3 , wherein:
at least one of the second extension or the third extension includes an extension body protruding in the first direction from the base, and
the contacting portion protrudes from the extension body.

5. The connector of claim 3 , wherein:
the extension body has a plate shape extending in a longitudinal direction and has a surface extending in the longitudinal direction, and
the contacting portion is provided on the surface of the extension body.

6. The connector of claim 3 , wherein:
the plurality of terminals include a plurality of contact portions each configured to contact a respective one of the plurality of mating terminals, and
at least one of the plurality of contact portions of the plurality of terminals and the contacting portion are arranged in a direction perpendicular to the first direction and the third direction.

7. The connector of claim 4 , wherein:
the extension body is accommodated in an accommodation portion out of the first accommodation portion and the second accommodation portion which accommodates the at least one of the second extension and the third extension therein, and
an accommodation space of the accommodation portion accommodating the extension body therein is larger than the extension body.

8. The connector of claim 1 , further comprising an outer shield held on the peripheral wall of the housing, the outer shield surrounding the plurality of terminals and the inner shield.

9. The connector of claim 8 , wherein:
the inner shield includes two tip regions,
the outer shield includes a first end located in the first direction and a second end opposite to the first end, and
a region of the outer shield including the second end faces at least one of the two tip regions with a gap in between.

10. A connector device comprising:
the connector of claim 1 ; and
the mating connector.

11. The connector of claim 1 , wherein:
the mating connector further includes a mating inner shield,
the first extension is disposed between the second extension and the third first extension, and
the second extension is located in the third direction from at least a part of the mating inner shield while the connector is connected to the mating connector.

12. The connector of claim 11 , wherein the third extension is located in a direction opposite to the third direction from at least a part of the mating inner shield while the connector is connected to the mating connector.

13. The connector of claim 1 , wherein:
the wall portion of the housing includes:
a first wall portion extending in a direction perpendicular to the first direction and the third direction, one terminal of the plurality of terminals being disposed on the first wall portion; and
a second wall portion extending in the direction perpendicular to the first direction and the third direction, another terminal of the plurality of terminals being disposed on the second wall portion,

the second extension and the third extension are disposed on the first wall portion and the second wall portion, respectively, and
the first extension is disposed between the first wall portion and the second wall portion.

14. A connector configured to be connected to a mating connector including a plurality of mating terminals, the connector comprising:
a plurality of terminals each configured to be electrically connected to respective one of the plurality of mating terminals while the connector is connected to the mating connector;
a housing holding the plurality of terminals; and
an inner shield held by the housing, wherein:
the connector is configured to be connected to the mating connector by moving toward the mating connector in a first direction relatively with respect to the mating connector,
the plurality of terminals include two terminals arranged on both sides of the inner shield in a second direction perpendicular to the first direction,
the housing includes:
a bottom wall having a surface directed in the first direction, the surface of the bottom wall facing a hollow space;
a peripheral wall protruding in the first direction from the surface of the bottom wall and surrounding the hollow space;
a first wall portion protruding in the first direction from the surface of the bottom wall disposed in the hollow space; and
a second wall portion protruding in the first direction from the surface of the bottom wall disposed in the hollow space,

the inner shield includes:
a base extending in a third direction which is perpendicular to the first direction and is different from the second direction;
a first extension protruding in the first direction from the base; and
a second extension protruding in the first direction from the base,

one terminal and another terminal of the plurality of terminals are disposed on the first wall portion and the second wall portion, respectively,
