Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact for a plug-in device such as a bus duct and a power distribution device.

[0002]

2. Description of the Related Art A conventional contact for a plug-in device comprises a contact piece arranged so as to sandwich a mating conductor from both sides, and an outer spring for pressing the contact piece from the outside. The contact piece is formed by bending a single leaf spring into an inverted U-shape, and the outer spring is composed of a single flat plate.
The outer spring assists the contact between the mating conductor and the contact piece.

[0003]

However, in the above-described structure, the contact between the mating conductor and the contact piece is surface contact, so that the contact area of the contact portion is not as large as apparent and the contact state is poor. There was a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a contact for a plug-in device capable of increasing a contact area between a mating conductor and a contact piece.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a contact for a plug-in device comprising a contact piece for contacting a mating conductor and an outer spring for pressing the contact piece from outside. A plurality of slits are provided in the insertion direction of the mating conductor of the contact piece, and a slit in the same direction as the slit is provided in the outer spring.

[0006]

The contact piece used in the contact for a plug-in device of the present invention is provided with a plurality of slits in the insertion direction of the mating conductor to which the contact piece is connected, and at a position corresponding to the slit of the contact piece of the outer spring. Since the slit is provided, the contact area between the mating conductor and the contact piece increases, and pressure is reliably applied to the contact piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. As shown in the drawing, the contact 4 for a plug-in device of the present invention comprises a contact piece 1 and an outer spring 2, and the contact piece is bent in an inverted U-shape. Five slits 5 are provided, and the outer spring 2 has two slits corresponding to the position of the long slit 5 of the contact piece 1.
A book slit 6 is provided.

[0008] A fixing hole 9 is provided below the contact piece 1 and the outer spring 2. The contact piece 1 and the outer spring 2 are fixed by a fixing member 8 so as to be sandwiched from both sides of the conductor 3.

The connection between the plug-in device contact 4 and the mating conductor 7 is performed by inserting the mating conductor 7 between the contact pieces 1. At this time, the contact surface between the mating conductor 7 and the contact piece 1 has an increased contact area due to the presence of five slits 5 in the contact piece 1, and the outer spring 2 applies pressure from the outside to assist this contact. doing. Since the outer spring 2 is also provided with the slit 6, the outer spring 2 plays a role of reliably applying pressure to the contact piece 1.

In this embodiment, the slit 5 of the contact piece 1 is used.
Is an example in which the outer spring 2 is provided with two short slits, and the outer spring 2 is provided with two short slits.
The number and length of 6 are not particularly limited and can be arbitrarily selected.

[0011]

As described above, the contact for a plug-in device according to the present invention has a plurality of slits in the insertion direction of the mating conductor to which the contact piece is connected, and the outer spring has the same direction as the slit. Since the slit is provided, the contact area between the mating conductor 7 and the contact piece increases, and pressure is reliably applied to the contact piece by the outer spring, so that the contact state is improved.
