Abstract

A connection structure connects a plate-like terminal main body (11) on the ground terminal fitting (10) in surface contact with a grounding member (20) that has female screw holes (41, 42) and a receiving portion (23). A wire connecting portion (12) on the ground terminal fitting (10) is connected to a wire (60). A lock (13) on the terminal main body (11) engages the receiving portion (23) and is on an axis line extension (70) of the wire (60). Mounting holes (151, 152) formed on the terminal main body (11) and aligned with the female screw holes (41, 42) by locking the lock (13) to the receiving portion (23). The ground terminal fitting (10) is connected to the grounding member (20) by screwing bolts (51, 52) inserted through the mounting holes (151, 152) into the female screw holes (41, 42).

Claims

1. A connection structure for connecting a plate-like terminal main body (11) provided on a ground terminal fitting (10) in surface contact with a grounding member (20), comprising:

a first female screw hole (41) formed on the grounding member (20);

a receiving portion (23) formed on the grounding member (20);

a wire connecting portion (12) formed on the ground terminal fitting (10) and connected to a wire (60);

a lock (13) formed on the terminal main body (11) to be able to be locked to the receiving portion (23) and arranged on an axis line extension line (70) of the wire (60) connected to the wire connecting portion (12); and

a first mounting hole (151) formed on the terminal main body (11) and to be aligned with the first female screw hole (41) by locking the lock (13) to the receiving portion;

the ground terminal fitting (10) being connected to the grounding member (20) by screwing a first bolt (51) inserted through the first mounting hole (151) into the first female screw hole (41).

2. The connection structure of claim 1, wherein a locking direction of the lock (13) to the receiving portion (23) is substantially parallel to an axial direction of the wire (60).

3. The connection structure of claim 2, wherein the lock (13) and the receiving portion (23) are capable of coming into contact with each other to prevent following rotation of the terminal main body (11) when the first bolt (51) is tightened.

4. The connection structure of claim 1, wherein:

the grounding member (20) further has a second female screw hole (42);

the terminal main body (11) is formed with a second mounting hole (152) corresponding to the second female screw hole (42); and

a difference between inner diameters of the second female screw hole (42) and the second mounting hole (152) exceeds a difference between inner diameters of the first female screw hole (41) and the first mounting hole (151).

5. The connection structure of claim 4, wherein:

the lock (13) and the receiving portion (23) contact each other to prevent following rotation of the terminal main body (11) when the first bolt (51) is tightened; and

a distance from the receiving portion (23) to the first female screw hole (41) exceeds a distance from the receiving portion (23) to the second female screw hole (42).
