Bl, which are provided in the printed circuit board side B.  In the state in which the fixing shield plate 23c is connected to the electrically conductive grounding passages B1 via the ground connection portions 23e in the manner described above, ground circuits are formed in the vicinity of the position in which the electromagnetic shielding (shielding) is effected by the fixing shield plate 23c.  The electrically conductive bonnet element 15, which is provided at a correspondence retaining element later described (correspondence actuating lever) 14 in the plug connector side (first connector) 1, is configured to come into contact with the fixing shield plate 23c in this manner.  [0054] [Correspondence retaining element] More specifically, the state of mutual correspondence of the two electrical connectors 1 and 2 in the case in which the plug connector (first connector) 1 is in correspondence with the receptacle connector 3035273 26 (second connector) 2 as the corresponding connector in correspondence in the manner described above is configured to be held by the retaining force of the correspondence holding member (correspondence actuating lever 5) 14, which is provided in plug connector 1.  It should be noted that when the plug connector 1 in correspondence with the receptacle connector 2 is to be removed from the receptacle connector 2, a state in which the two electrical connectors 1 and 2 can be removed from one of the another is obtained by performing an operation of opening the correspondence retaining element 14.  In more detail, as shown in FIG. 6, the correspondence retaining member 15 (correspondence actuating lever) 14 is rotatably attached to the first shielding case member 13 of the the plug connector described above (first connector) 1, and rotational axis portions 14a and 14a, which are provided at portions at both ends in the longitudinal connector direction of the correspondence holding member 14, are rotatably inserted into a loose correspondence state in bearing portions 13d and 13d, which are provided at portions at both ends in the longitudinal connector direction of the rear end portion of the first shielding casing 13.  The pair of rotation axis portions 14a and 14a, which are provided in the correspondence holding member (correspondence operating lever) 14, is formed to form approximately circular shapes as shapes. cross-sectionally and extend in the longitudinal connector direction and have unequal portions in the radial direction (offset-axis portions) at intermediate portions in the

vicinity of the "shielded position (matched working position)" once the two electrical connectors 1 and 2 are mutually matched, the arm portions of the Coupling 14b, which are provided in the correspondence retaining element 14, move over the outwardly bulging portions of the locking portions 23f of the receptacle connector 2 side described above, are then displaced. so as to be resiliently displaced to the connector inner side, and are released to the lower side of the locking portions 23f, thereby causing the two to be in a engaged state; and as a result, the entirety of the correspondence retaining element 14 is resiliently held in the "shielded position (matching working position)".  When the correspondence retaining element (correspondence actuating lever) 14 is rotated from the "unshielded position (correspondence position released) to the" shielded position (working position in correspondence) " in the state in which the plug connector (first connector) 1 is in correspondence with the receptacle connector (second connector) 2 in this manner, the two electrical connectors 1 and 2 are maintained in the mutual correspondence state without to be separated

members) 22.  Since the upper surface shielding cap 15a of the electrically conductive bonnet member 15 is in an arrangement relation in which it faces the rear end portions including the card connecting leg portions 22a of In this manner, the electrically conductive contacts 3035273 31 overlap with the upper side in this manner, the electromagnetic shielding (shielding) in the up-down direction perpendicular to the surface of the printed circuit B is realized.  In addition, the side portion fixing plates 15b of the electrically conductive bonnet member 15 are provided to protrude

resistance of the matching retainer 14 is sufficiently maintained.  As an embodiment which exerts a similar effect, the correspondence holding member may be formed by a rod-shaped member which forms a rectangular cross-section.  [0079] Here, with regard to the correspondence retaining element (correspondence actuating lever) 14, the locking parts 23f, which hold the correspondence retaining element 14 in the "shielded position" (position matching) ", are provided in the receptacle connector (second connector) 2.  Therefore, the state of mutual correspondence of the two electrical connectors 1 and 2 is well maintained by the locking portions 23f.  On the other hand, in the present embodiment, the resilient spring members (elastic spring members) 15g, which are shaped to extend into cantilevered shapes on the electrically conductive bonnet member 15, are bent at extended and extended intermediate positions, and the contact point portions provided on the elastic spring members 15g

sufficient extension lengths of the elastic spring members 15g are provided, and a necessary elasticity of the resilient spring members 15g can be maintained.  Here, the attachment shielding plate 23c of the second shielding case member 23 as an associated member in which the resilient spring members (resilient spring members) 15g are in contact are provided with the 23g housing contact, which comprises the folded portion of the attachment shield plate 23c.  Therefore, the resilient spring members 15g are configured to be in good contact relation with respect to the housing contact piece 23g so that the electrical connectivity of the ground circuit is improved.  [0082] Above, the invention made by the present inventors has been described in detail based on the embodiments.  However, the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without departing from the essentials thereof.  For example,
