The first contact 2a, the second contact 2b, and the third contact 2c may be supported by the base contact 2d.

The support contact 2e is connected to the second contact 2b. The support contact 2e can be connected to the second contact 2b as the second contact 2b is connected to the second card C2. Accordingly, the second contact 2b is connected to the support contact 2e, thereby limiting the distance that the second contact 2b moves in the downward direction (direction of the arrow DD).

8 and 9, the second contact 2b of the card connector 1 according to the present invention includes a fixing member 21b (shown in Fig. 9), a connecting member 22b (shown in Fig. 9) A first inclined member 23b (shown in Fig. 9), and a second inclined member 24b (shown in Fig. 9).

The fixing member 21b is intended to be coupled to the base contact 2d. The fixing member 21b may be fixed to the insulating body 30 by being coupled to the base contact 2d. The second contact 2b may be fixed to the base contact 2d as the fixing member 21b is coupled to the base contact 2d. The fixing member 21b is disposed between the base contact 2d and the first inclined member 23b.

And the connection member 22b is for being connected to one surface of the card C. [ The connection member 22b may be connected to one surface of the card C and electrically connected to the card C. [ The second contact 2b may be coupled to the insulating body 30 such that the connecting member 22b is located in the coupling groove 31. [ The second contact 2b may be coupled to the first insulating body 30a or the second insulating body 30b such that the connecting member 22b is located in the coupling groove 31. [ The connection member 22b may be formed so that a portion connected to the card C has a curved surface. In this case, the connecting member 22b may be formed to be curved through bending.

The first inclined member 23b is located between the fixing member 21b and the connecting member 22b. One end of the first inclined member 23b may be coupled to the fixing member 21b and the other end may be coupled to the connection member 22b. The first inclined member 23b is located at a position where the fixing member 21b is defective in the first insulating body 30a and the connecting member 22b can be connected to the second card C2 As shown in Fig. For example, the first inclined member 23b may be inclined so that the height of the first inclined member 23b increases from the fixing member 21b toward the connecting member 22b. Accordingly, the connecting member 22b can be elastically moved depending on whether or not it is connected to the card C.

The second inclined member 24b may be coupled to the connecting member 22b. The second inclined member 24b can be coupled to the connecting member 22b in a direction opposite to the direction in which the first inclined member 23b is coupled to the connecting member 22b. For example, when the first inclined member 23b is positioned in the second direction (SD arrow direction) with respect to the connecting member 22b, the second inclined member 24b is inclined with respect to the connecting member 22b And can be coupled to the connecting member 22b in the first direction (direction of arrow FD).

The second inclined member 24b may be inclined so that the height of the second inclined member 24b decreases from the fixing member 21b toward the connecting member 22b. Accordingly, the second inclined member 24b can limit the moving distance of the connecting member 22b. The second inclined member 24b can limit the distance that the connecting member 22b moves in the downward direction (DD arrow direction) as the connecting member 22b is connected to the card C. [ The second inclined member 24b is connected to the supporting contact 2e as the connecting member 22b is connected to the card C so that the connecting member 22b is moved in the downward direction As shown in FIG. 9, the support contact 2e is located on the upper side of the fixing member 21b, so that the distance by which the connection member 22b moves in the downward direction (direction of the arrow DD) can be limited .

The inclined angle? 1 between the first inclined member 23b and the substrate 100 may be greater than the inclined angle? 2 between the second inclined member 24b and the substrate 100 . Accordingly, the card connector 1 according to the present invention can reduce an increase in length in the second axial direction (Y-axis direction).

These effects are as follows. As described above, in the card connector 1 according to the present invention, the second contact 2b has one side joined to the first insulating body 30a and the other side extended toward the first direction (arrow direction of the FD) (Y-axis direction) of the second insulation body (30b), the second insulation body (30b) is overlapped with the second insulation body (30b) with respect to the second axis direction And is coupled to the second card C2. The first inclined member 23b is inclined upward from the fixing member 21b in the direction of the arrow UD so that the inclined angle? 1 between the first inclined member 23b and the substrate 100 Of the second inclined member 24b is less than or equal to the inclination angle? 2 between the second inclined member 24b and the substrate 100, the connection member 22b can be connected to the second card C2 There is a limit in reducing the length of the first inclined member 23b in the second axial direction (Y-axis direction) so as to be formed up to the height. Therefore, in the card connector 1 according to the present invention, the inclined angle [theta] 1 between the first inclined member 23b and the substrate 100 is smaller than the inclined angle [theta] 1 between the second inclined member 24b and the substrate 100 (Y-axis direction) of the first inclined member 23b is reduced to be larger than the second axial direction (Y-axis direction) by reducing the length of the first inclined member 23b in the second axis direction Can reduce the overall length.

The length L1 of the first inclined member 23b may be longer than the length L2 of the second inclined member 24b. Accordingly, the card connector 1 according to the present invention can extend the service life of the second contact 2b by reducing the plastic deformation occurring in the first inclined member 23b, The connecting force between the connecting member 22b and the card C can be further increased.

These effects are as follows. The length of the first inclined member 23b and the length of the second inclined member 24b may be adjusted so that the length of the second contact 2b relative to the second axis direction (Y axis direction) The value should be designed not to exceed a predetermined value. On the other hand, according to the comparative example in which the length L1 of the first inclined member 23b is less than the length L2 of the second inclined member 24b, the connection member 22b and the card C , The service life of the second contact 2b is shortened due to the plastic deformation occurring in the first inclined member 23b. Therefore, the board connector 1 according to the present invention is configured such that the first inclined member 23b is formed to be longer than the second inclined member 24b so that plastic deformation occurring in the first inclined member 23b And the elastic displacement can be increased.

Although not shown, the first contact 2a and the third contact 2c may have the same structure as that of the second contact 2b, but the present invention is not limited thereto, The first contact 2a and the third contact 2c may be formed in a structure different from the second contact 2b.

The receiving groove 43 may be located between the first lower mounting member 41a and the first upper mounting member 51a. One of the first lower mounting members 41a and one of the first upper mounting members 51a are arranged to be spaced apart from each other with the receiving groove 43 therebetween and the first lower mounting member 41a And the rest of the first upper mounting members 51a may be disposed at the same position with respect to the first axial direction (X-axis direction).

The first upper mounting member 51a disposed to be spaced apart from one of the first lower mounting members 41a with the receiving groove 43 therebetween may be coupled to the lower shell body 40. [ The first upper mounting member 51a may be coupled to the lower shell body 40 through welding. Therefore, the card connector 1 according to the present invention can maintain a more stable coupling force by direct coupling of the lower shell body 40 and the upper shell body 50. [ However, since the present invention is not limited to this, the lower shell body 40 and the upper shell body 50 may be coupled in a coupling manner other than welding.

The upper end shell body 50 can be fixedly coupled to the lower shell body 40 by being inserted into the fitting recess 45 in an interference fit manner. A groove may also be formed in the substrate 100 so as to communicate with the fitting groove 45 in an area where the lower mounting member 41 is mounted so as to provide a space into which the shim member 54 can be inserted .

Accordingly, the card connector 1 according to another embodiment of the present invention is fixedly coupled to the lower shell body 40 via the fitting member 54. [0053] 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 to each other with the insulating portion 3 interposed therebetween, It is possible to stably protect the contacts 3 and the contacts 2 coupled to the insulation part 3 and reduce the deterioration of the bonding force with respect to the substrate 100 due to vibration,

Accordingly, the card connector 1 according to another embodiment of the present invention is configured such that the lower shell main body 40 and the upper shell main body 50 are positioned in the downward direction (DD arrow direction) with respect to the connecting member 61 The connection member 61 can be stably supported 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 (the direction of the arrow UD), and may be bent to have an upper surface facing the upper direction (the direction of the arrow U). The fitting member 54 may be inserted into the fitting groove 45 by protruding from the upper surface of the bending member 55 in the downward direction (direction of the arrow DD). That is, since the fitting groove 45 is formed to penetrate through the lower mounting member 45 with reference to the third axial direction (Z-axis direction) as described above, in order to be inserted into the fitting groove 45 The shim member 54 should be formed along the lower direction (DD arrow direction). Accordingly, the card connector 1 according to another embodiment of the present invention can provide a height at which the shim member 54 can be inserted into the fitting groove 45 through the bending member 55.
