The fitting grooves 45 may be formed to be spaced apart from each other along the second axial direction (Y-axis direction) on each of both sides of the lower shell body 40 .

When the lower shell 4 includes the fitting groove 45 , the upper shell 5 may include a fitting member 54 (shown in FIG. 19 ).

The fitting member 54 is for fixing the upper shell body 50 to the lower shell body 40 . The fitting member 54 may be formed to protrude from the side wall 501 of the upper shell body 50 . The fitting member 54 may be formed to protrude from the sidewall 501 of the upper shell body 50 toward the downward direction (the DD arrow direction). The upper shell body 50 may be coupled to the lower shell body 40 such that the fitting member 54 is inserted into the fitting groove 45 . The fitting member 54 is inserted into the fitting groove 45 in an interference fit manner, whereby the upper shell body 50 may be fixedly coupled to the lower shell body 40 . A groove may also be formed in the substrate 100 so as to communicate with the fitting groove 45 in the region where the lower mounting member 41 is mounted so as to provide a space into which the fitting member 54 can be inserted. .

Accordingly, in the card connector 1 according to another embodiment of the present invention, the upper shell body 50 is fixedly coupled to the lower shell body 40 through the fitting member 54 . Accordingly, in the card connector 1 according to another embodiment of the present invention, the upper shell body 50 and the lower shell body 40 are firmly coupled with the insulating part 3 therebetween, thereby providing the insulation. The contact 2 coupled to the part 3 and the insulating part 3 can be stably protected, and deterioration of the bonding force to the substrate 100 due to vibration, shaking, etc. can be reduced.

Referring to FIG. 19 , the upper shell 5 may include a lower plate 502 (shown in FIG. 19 ) and a bending member 55 (shown in FIG. 21 ).

The lower plate 502 may be formed in the upper shell body 50 so as to contact the lower shell body 40 in the receiving groove 43 . The lower plate 502 is for connecting the side wall 501 of the shell body 50 and the bending member 55 . The lower plate 502 may be positioned between the side wall 501 of the shell body 50 and the bending member 55 in the first axial direction (X-axis direction). The lower plate 502 may be formed to extend from the side wall 501 of the upper shell body 50 so as to be positioned in the lower direction (DD arrow direction) with respect to the connection member 61 . Therefore, in the card connector 1 according to another embodiment of the present invention, the lower shell body 40 and the upper shell body 50 are in the lower direction (DD arrow direction) with respect to the connection member 61. By being positioned so as to be positioned, it is possible to stably support the connection member 61 in the process of inserting and withdrawing the tray 10 .

The bending member 55 may be formed to protrude from the lower plate 502 in the upward direction (UD arrow direction), and be bent to have an upper surface facing the upward direction (UD arrow direction). The fitting member 54 may be inserted into the fitting groove 45 by being formed to protrude from the upper surface of the bending member 55 in the downward direction (in the direction of the DD arrow). That is, since the fitting groove 45 is formed to pass through the lower mounting member 45 with respect to the third axis direction (Z axis direction) as described above, in order to be inserted into the fitting groove 45 , The fitting member 54 should be formed along the downward direction (DD arrow direction). Accordingly, the card connector 1 according to another embodiment of the present invention can provide a height at which the fitting member 54 can be inserted into the fitting groove 45 through the bending member 55 .

In the above, an example in which the upper shell 5 is coupled to the lower shell 4 by inserting the fitting member 54 into the fitting groove 45 has been described, but the present invention is not limited thereto. For example, referring to FIG. 19 , the lower shell 4 includes a fitting member 46 formed to protrude from the bottom surface of the lower shell body 40 toward the upward direction (UD arrow direction), and the upper shell (5) is also possible to be implemented to include a fitting groove formed to penetrate the upper shell body (50). Specifically, the fitting member 46 may be formed to protrude toward the upper direction (UD arrow direction) from the lower shell body 40 in which the receiving groove 43 is formed.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention.
