When the connection clip 1 according to the present invention includes a plurality of connection members 10, the height of the contact portion of the connection member may be different.

A contact portion that comes into contact with the busbar is formed on the upper portion of the connecting member. When a plurality of connecting members are provided in one cover member, the height of the contact portion may be the same, but may be formed differently.

The plurality of connecting members may be formed differently for all of the plurality of connecting members.

In the plurality of connecting members, a contact portion of at least one connecting member of the connecting member may be formed different from the height of the contact portion of the remaining connecting members.

The height of the contact portion is a height formed based on the insertion direction of the busbar inserted into the connecting member and energized.

A detailed example will be described as follows.

Referring to Figure 6, in the case of a structure including four connecting members 11, 12, 13, 14, two connecting members 11, 13 and the remaining two connecting members 12 (12) ( The contact portions 12a and 14a of 14) may be formed at different heights.

Of course, the heights of the contact portions 11a, 12a, 13a, and 14a of the four connecting members 11, 12, 13, and 14 may be formed differently.

The height of the contact portions 12a and 14a of the two connecting members 12 and 14 may be formed at a lower position than the contact portions 11a and 13a of the remaining two connecting members 11 and 13.

The contact parts 11a, 12a, 13a, 14a are parts that allow contact for electric current with the busbar B to be connected when installed in the switchboard or MCC, and the connecting members 11, 12 ( 13) It has a structure formed to protrude from (14).

Since the contact portions 12a and 14a of the connecting members 12 and 14 are formed at a lower position than the contact portions 11a and 13a of the other two connecting members 11 and 13, When connecting, the busbars are first connected at the contact portions 11a and 13a of the two connecting members 11 and 13 formed at high positions, and then the connecting members 12 and 14 Connection may be made to the contact portions 12a and 14a of.

Since the connecting members of the connecting clip 1 are mutually pressed by the elastic member 50, when the busbar and the connecting clip 1 are connected, the connecting members are separated by the pressing force provided by the elastic member 50. It requires considerable force to penetrate.

In the case of a connection clip assembled with four connection members, a stronger connection force may be required.

Therefore, when connecting the connection clip (1) having a plurality of connection members (11) (12) (13) (14) with the bus bar (B), first, the bus bar (B) is two connecting members (11) It contacts the contact portions 11a, 13a of (13), and then comes into contact with the contact portions 12a, 14a of the connecting members 12, 14, so that the connection operation with the busbar is reduced with less force. Can be done.
