In the above configuration, the plurality of shielded electric wires 21 are grounded to the ground member 25 in a procedure (one example) as described below, so that the electromagnetic wave shielding processing is achieved.

First, the first holding portion 23 is connected to the ground member 2.

The bolts 33, 33 are screwed into the screw holes 34, 3
During the screwing of the second holding portion 4, the second holding portion 24 gradually comes closer to the first holding portion 23, so that the first holding portion 23 having each portion having the spring property is as follows. Works.

That is, in FIG.
When the screwing of 33 is started, each of the electrical contact portions 36, 36, 3
A load (longitudinal load) in the direction of the arrow P is applied to the terminal contact portion 6 from the terminals 22, 22, 22 side. Further, a lateral load in the direction of arrow Q is applied to both ends of the electric contact portions 36, 36, 36. Then, when the screwing of the bolts 33, 33 proceeds,
Due to the lateral load in the direction of the arrow Q, the connecting portions 37, 37, 3

6, 36, 36 between the connecting portions 37, 37, 37,
It expands according to the amount of deflection of 37. As a result, the position of the terminal contact portion of each of the electric contact portions 36, 36, 36 moves to the flat one surface side of the ground member 25 (moves in the direction of arrow P). In the case where the connecting portions 37, 37, 37, 37 are sufficiently bent to further advance the screwing of the bolts 33, 33, the spring properties of the electric contact portions 36, 36, 36 themselves are used similarly to the conventional example.

37 ', 37'.

Each connecting portion 37 'is connected to the first holding portion 23.
Is formed in the same manner as that in which the opening portion 44 is provided for the connecting portion 37. Further, each connecting portion 37 ′ is more flexible than the connecting portion 37 of the first holding portion 23.

That is, each connecting portion 37 'is formed with the opening 4
4 and a pair of connecting portions 45, 45. The opening 44 is formed to penetrate including the position of the top of the connecting portion 37 of the first holding portion 23, and the connecting portions 4 are formed on both sides thereof.
5, 45 are arranged and formed. Connecting parts 45, 45
Is formed in a substantially inverted U-shape in the same front view as the connecting portion 37 of the first holding portion 23.

It is needless to say that even when the first holding portion 23 'having the above structure is used, it is possible to provide an electromagnetic wave shielding processing structure which enables inexpensive and stable contact (the first holding portion 23'). ′ Is the same as that of the first holding portion 23, and the description is omitted).

As shown in the graph of FIG. 5, (the range A is the use range related to the bending of the conventional example. The range B is the use range related to the bending of the first holding portion 23. The range C is the first holding portion 2.
3 ') The use range related to bending is wider when the first holding portion 23' is used.
It is more effective than the first holding portion 23.
