Abstract

A connector includes a housing and a terminal held in the housing and to be mounted on a mounting member disposed outside the housing. The terminal includes a main body part inserted into a space formed in the housing, a leg part extending from the main body part toward a mounting surface of the mounting member in a state where the terminal is mounted on the mounting member, and a mounting part provided continuously from the leg part and to be mounted on the mounting member. The connector further includes a leg part holder connected to the housing and to hold the leg part.

First claim

The invention claimed is:

1. A connector, comprising:
a housing;
a terminal held in the housing and to be mounted on a mounting member disposed outside the housing, wherein the terminal includes
a main body part extending along a first direction and inserted into a space formed in the housing,
a leg part extending along a second direction different from the first direction, and
a mounting part provided continuously from the leg part and to be mounted on the mounting member and

a groove formed in a wall of the space, wherein the leg part is held by the groove when the main body part is inserted into the space.

2. The connector according to claim 1 , wherein
the leg part is formed into a plate shape, and
in a state where the main body part is inserted into the space and the mounting part is mounted on the mounting member, a plate thickness direction of the leg part corresponds to a direction intersecting with an insertion direction of the main body part into the space and with a direction normal to the mounting surface.

3. The connector according to claim 1 , wherein
the housing has a receiving part to receive the mounting member in a wall on one side in a housing thickness direction, and
the leg part extends in the housing thickness direction from the main body part.

4. The connector according to claim 1 , wherein
the groove is integrally formed with the housing.

5. The connector according to claim 1 , wherein
the space includes
a first space formed in the housing and
a second space formed at a position further away from the mounting surface than the first space in the housing in a state where the main body part is inserted into the space and the mounting part is mounted on the mounting member,

the terminal includes
a first terminal having a first main body part inserted into the first space, a first leg part extending from the first main body part toward the mounting surface in a state where the terminal is mounted on the mounting member, and a first mounting part provided continuously from the first leg part and to be mounted on the mounting member, and
a second terminal having a second main body part inserted into the second space, a second leg part extending from the second main body part toward the mounting surface in a state where the terminal is mounted on the mounting member, and a second mounting part provided continuously from the second leg part and to be mounted on the mounting member, and

at least either one of the first and second leg parts is held by the leg part holder groove.

6. The connector according to claim 5 , wherein
the first space and the second space overlap with each other when the housing is viewed along the direction normal to the mounting surface in a state where the terminal is held by the housing and mounted on the mounting member.

7. The connector according to claim 6 , wherein
a first insertion opening of the first space is divided into two regions by the second leg part when the housing is viewed along the insertion direction of the main body part into the space in a state where the main body part is inserted into the space, and
the second leg part is held by the leg part holder at two spots across the first insertion opening.

8. The connector according to claim 5 , wherein
the first mounting part is provided continuously from the first leg part so as to protrude toward one side in the insertion direction of the main body part into the space, and
the second mounting part is provided continuously from the second leg part so as to protrude toward the other side in the insertion direction of the main body part into the space.

9. The connector according to claim 8 , wherein
either one of the first and second mounting parts overlaps with the housing when the housing is viewed along the direction normal to the mounting surface in a state where the terminal is held by the housing and mounted on the mounting member.

10. The connector according to claim 1 , comprising:
a plurality of the terminals,
wherein the mounting parts are arranged in a staggered pattern in a state where the plurality of terminals are held by the housing.

11. The connector according to claim 1 , wherein
the main body part includes a bottom wall and a side wall provided continuously from the bottom wall,
a tip of the side wall is inserted into the groove such that the groove guides insertion of the main body part into the space,
the space includes an insertion opening opened toward the outside of the housing and an insertion main cavity which communicates with the insertion opening and in which to house the main body part of the terminal, and
the groove is formed in the insertion main cavity.

12. The connector according to claim 11 , wherein
a length of the groove in an insertion direction is not shorter than a distance by which the main body part moves between the start and end of insertion of the tip of the side wall.

13. The connector according to claim 11 , wherein
the groove extends beyond the center of the space to an inner side of the space in the insertion direction.

14. The connector according to claim 11 , wherein
the insertion opening has a second groove formed therein to guide insertion of the main body part into the space, and
the second groove communicates with the groove.

15. The connector according to claim 11 , wherein
the side walls are provided continuously from both ends of the bottom wall in the width direction, and
one of the side walls has an extension wall formed therein, which protrudes, more than the other side wall, in the insertion direction of the main body part into the space.

16. A connector terminal used in the connector according to claim 15 .

17. A connector comprising:
a plurality of terminals to which an electric wire is connected respectively;
a housing having a plurality of spaces formed therein, into which the terminal is inserted respectively; and
a retainer attached to the housing, and to restrict fall-off of the terminals from the housing,
wherein the terminals each include
a terminal main body part having a peripheral wall extending in an insertion direction of the terminal into the space,
a contact part provided continuously from one side, in the insertion direction, of the terminal main body part, and
an electric wire connector part provided continuously from the other side, in the insertion direction, of the terminal main body part, and to have the electric wire connected thereto,

wherein a first insertion hole is formed in the peripheral wall,
wherein a second insertion hole, facing the first insertion hole, is formed in the peripheral wall,
wherein the contact part is formed at a position off the center of the electric wire extending in the insertion direction, when viewed along the insertion direction,
wherein a distance between the first insertion hole and the contact part is larger than a distance between the second insertion hole and the contact part,
wherein the spaces include a first space and a second space,
wherein the retainer includes
a third space formed therein, and
