つ以上形成されていることが好ましい。By configuring the connector locking member 70 as described above, the elastic contact piece 76 presses the laminate sheet 82 against the outer peripheral surface of the connector main body 80 by its elastic force.
That is, according to the electromagnetic shield structure to which the connector locking member 70 is applied, as shown in FIG. 8, after the laminate sheet 82 covering the electric wires 2 is covered on the connector main body 80, the connector locking member 70 is , So that the lock holes 7 are fitted on the connector body 80 on the laminate sheet 82.
4a and the lock claw portion 74b are locked and cylindrically connected. In this manner, when the holding portions 72a and 72b are connected to each other, the elastic contact piece 76 is pressed by the connector body 80 and elastically deforms. That is, since an elastic force is generated in the elastic contact piece 76, the laminate sheet 82 is strongly pressed against the outer peripheral surface of the connector main body 80 by the elastic force. Therefore, even if vibration occurs in the vehicle and acts to create a gap between the connector body 80 and the connector locking member 70, the laminate sheet 82 is retained by the distal end portion 76 a of the elastic contact piece 76. Is always in stable contact. Although a plurality of elastic contact pieces 76 are formed in the circumferential direction of the connector locking member 70, at least three elastic contact pieces 76 are spaced apart at equal intervals.
Preferably, at least one is formed.

In each of the above embodiments, a pressing spring and an elastic piece are used as the elastic member, and the laminate sheet is strongly pressed against the connector body by the pressing spring and the elastic contact piece. In this embodiment, the pressing spring and the elastic contact piece are used. Instead, inexpensive elastic members are used. That is, a rubber packing 40 as an elastic member is wound around the outer peripheral portion of the laminate sheet 15 fitted to the connector main body 6. On the other hand, the connector locking member 8A
The two holding portions 2 are similar to the first and third embodiments.
It is provided in a two-part structure consisting of 1a and 21b, and the holding portions 21a and 21b are mutually connected and integrated. However, these holding portions 21a and 21b have first and third

け作業も一層簡単化できて低コスト化を図れる。As described above, according to the electromagnetic shield structure of the present invention, the elastic member for pressing the conductive sheet against the connector main body is provided, and the conductive sheet is pressed against the connector main body by the elastic force of the elastic member. be able to. Therefore, even when vibration of the vehicle or the like occurs, the conductive sheet always and stably contacts the connector main body. As a result, the shielding performance of the electromagnetic shield structure is improved, and the reliability can be improved. In addition, if the elastic member is attached to the inner peripheral portion of the connector engaging member, the elastic member can be easily attached only by assembling the connector engaging member, and no special operation for improving the shielding performance is required. Further, if the elastic member is an elastic contact piece integrally formed with the connector locking member, the number of components can be reduced, and the assembling work can be further simplified, and the cost can be reduced.
