Abstract

A device connector includes a first housing (20) accommodating first terminals (30) connected to terminals of a device and a second housing (40) accommodating second terminals (55) connected to ends of wires (50) and connectable to the first housing (20). Connecting portions (31, 56) of the first and second terminals (30, 55) are placed one over the other and bolted as the housings (20, 40) are connected. The first housing (20) has a work hole (34) for bolting the connecting portions (31, 56) of the terminals (30, 55) together. A metal shield shell (60) covers the connected housings (20, 40) and is bolted to a case (10) at three mounting portions (65, 66) and (97) arranged on an outer part of the shield shell (60) to form a triangle having substantially equal sides.

Claims

1. A device connector to be connected to at least one terminal of a device housed in a conductive case, comprising a first housing (20) accommodating at least one first terminal (30) to be connected to the terminal of the device and a second housing (40) accommodating at least one second terminal (55) to be connected to an end of a wire (50) and connectable to the first housing (20), wherein:

connecting portions (31, 56) of the corresponding first and second terminals (30, 55) being placed one over the other and bolted as the two housings (20, 40) are connected, the first housing (20) having at least one work hole (34) used to bolt the connecting portions (31, 56) of the terminals (30, 55) together; and

a shield shell (60) made of conductive material and arranged to at least partly cover the connected housings (20, 40), three mounting portions (65, 66, 97) being arranged on the shield shell (60) for fixing the shield shell (60) to the case by bolting.

2. The device connector of claim 1, wherein the three mounting portions (65, 66, 97) are arranged on an outer edge part of the shield shell (60) to form a triangle, a ratio of a longest side to a shortest side of the triangle being about 1.8 or less.

3. The device connector of claim 2, wherein the triangle has substantially equal sides.

4. The device connector of claim 1, wherein the shield shell (60) has a shell main body (61) for covering connected parts of the two housings (20, 40) and a shell cover (85) for covering the work hole (34) while partly overlapping the shell main body (61).

5. The device connector of claim 4, wherein the shell main body (61) and the shell cover (85) are joined by bolting.

6. The device connector of claim 4, wherein the shell main body (61) has two of the mounting portions (65, 66) and the shell cover (85) has one (97) of the mounting portions (65, 66, 97).

7. The device connector of claim 4, further comprising convex/concave engaged positioning portions (72;

92) provided between the shell main body (61) and the shell cover (85) for positioning the shell main body (61) and the shell cover (85) and preventing the shell main body (61) and the shell cover (85) from rotating or displacing when bolting.

8. The device connector of claim 4, wherein the shell cover (61) is made of a metal plate and formed by integrally joining the cover main body (86) and mounting portion (95) by welding, the cover main body (86) being made of a thinner material than the mounting portion (95).

9. The device connector of claim 8, wherein the mounting portion (95) is reinforced by at least one side wall (95A) and at least one raised portion (98A).
