Abstract

A connector includes a holding member, a contact, a shell and a ground member. The holding member is made of insulator defining a connection space. The contact has a contact point. The contact is held by the holding member. The contact point is located inside the connection space. The ground member is electrically connected to the shell. The ground member has a base portion, a ground spring portion and a ground contact point portion. The base portion is located between the holding member and the shell. The base portion is provided with a regulated portion sandwiched between the shell and the holding member. The ground spring portion extends from the base portion. The ground contact point portion is supported by the ground spring portion and protrudes into the connection space. In the front-rear direction, a position of the ground spring portion does not overlap with a position of the contact.

First claim

The invention claimed is:

1. A connector mateable with a mating connector, which has a mating ground portion, in a front-rear direction, wherein:
the connector comprises a holding member, a contact, a shell and a ground member;
the holding member is made of insulator defining a connection space;
the contact has a contact point;
the contact is held by the holding member;
the contact point is located inside the connection space;
the shell covers the holding member at least in part;
the ground member is electrically connected to the shell;
the ground member has a base portion, a ground spring portion and a ground contact point portion;
the base portion is located between the holding member and the shell;
the base portion is provided with a regulated portion sandwiched between the shell and the holding member, movement of the regulated portion being regulated;
the ground spring portion extends from the base portion;
the ground spring portion has a first spring portion, a second spring portion and a third spring portion;
the first spring portion extends rearward in the front-rear direction;
the second spring portion extends from a rear end of the first spring portion in a lateral direction perpendicular to the front-rear direction;
the third spring portion extends forward in the front-rear direction from the second spring portion;
the ground contact point portion is connected to the mating ground portion when the connector is mated with the mating connector;
the ground contact point portion is supported by the third spring portion and protrudes into the connection space; and
a position of the ground spring portion does not overlap with a position of the contact in the front-rear direction.

2. The connector as recited in claim 1 , wherein a position of the ground member does not overlap with the position of the contact in the front-rear direction.

3. The connector as recited in claim 1 , wherein:
a ground accommodation portion is formed between the shell and the holding member; and
the ground accommodation portion accommodates at least the first spring portion, the second spring portion and the base portion.

4. The connector as recited in claim 3 , wherein:
the holding member is formed with a partition wall and an aperture;
the partition wall separates the ground accommodation portion and the connection space from each other;
the aperture penetrates the partition wall; and
the third spring portion and the ground contact point portion are arranged corresponding to the aperture.

5. The connector as recited in claim 4 , wherein:
the partition wall has a first regulating portion, which regulates movement of the first spring portion, and a second regulating portion, which regulates movement of the second spring portion; and
the first regulating portion extends diagonally to be directed inward in an up-down direction perpendicular to both of the front-rear direction and the lateral direction and to be directed rearward in the front-rear direction.

6. The connector as recited in claim 1 , wherein the ground member is further provided with a spring piece which is pressed against the shell.

7. The connector as recited in claim 6 , wherein:
the base portion extends in the front-rear direction; and
the spring piece has an L-shape and extends from the base portion in the lateral direction.

8. The connector as recited in claim 1 , wherein:
the ground spring portion further comprises an additional spring portion extending from the base portion in the lateral direction; and
the first spring portion extends rearward in the front-rear direction from the additional spring portion.

9. The connector as recited in claim 8 , wherein:
the additional spring portion has a first front end portion, a second front end portion and a coupling portion;
the first front end portion is located forward of the ground contact point portion in the front-rear direction and located at a position overlapping with the ground contact point portion in the lateral direction;
the second front end portion is located rearward of the first front end portion in the front-rear direction and located apart from the first front end portion in the lateral direction;
the coupling portion couples the first front end portion and the second front end portion to each other; and
the first spring portion extends from the second front end portion.

10. The connector as recited in claim 8 , wherein:
the ground member comprises two of the base portions, two of the first spring portions, three of the third spring portions and three of the ground contact point portions;
the two base portions are located apart from each other in the lateral direction;
the additional spring portion connects the two base portions together in the lateral direction;
the two first spring portions are located inward of the two base portions in the lateral direction;
one of the three third spring portions is located inward of the two first spring portions in the lateral direction while remaining two are located outward of the two first spring portions in the lateral direction; and
the three ground contact point portions are held by the three third spring portions, respectively.

11. The connector as recited in claim 1 , wherein the second spring portion is located between a front end of the first spring portion and the ground contact point portion in an up-down direction perpendicular to both of the front-rear direction and the lateral direction.
