The second contact 2b may be formed to overlap the first insulating body 30a and the second insulating body 30b based on the second axial direction (Y-axis direction). The third contact 2c may be coupled to the second insulating body 30b and connected to the third card C3. The third contact 2c may be formed to overlap only the second insulating body 30b with respect to the second axial direction (Y-axis direction).

The first contact 2a may be connected to the first card C1 positioned in the lower direction (DD arrow direction) of the cards C stacked along the third axis direction (Z-axis direction). will be.

That is, according to a comparative example in which the cards C are inserted into the coupling groove 31 on the same plane so that the contacts 2 are respectively connected to the cards C, the cards C are accommodated in the tray 10. As the number of the cards C increases, the card connector 1 needs to provide a space into which the tray 10 can be inserted, thereby increasing its area. Accordingly, the card connector 1 according to the present invention may allow the contacts 2 and the substrates to electrically connect the cards C and the substrate 100 respectively accommodated in the tray 10 at different heights.

By being formed to overlap, length increase in the second axial direction (Y-axis direction) can be reduced. For example, according to a comparative example in which the second contact 2b is formed to overlap only the first insulating body 30a or the second insulating body 30b, the first insulating body 30a or the second insulating body 30b. Since 30b must be formed to have a length that can accommodate the second contact 2b, there is a limit in reducing the length in the second axial direction (Y-axis direction).

One side of the first inclined member 23b may be coupled to the fixing member 21b, and the other side thereof 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 second insulating body 30b and the connection member 22b can be connected to the second card C2. It may be formed to be inclined to. For example, the first inclined member 23b may be formed to be inclined so as to increase in height from the fixing member 21b toward the connection member 22b. Accordingly, the connection member 22b can be elastically moved depending on whether or not the connection member 22b is connected to the card (C).

The second inclined member 24b is positioned between the connecting member 22b and the limiting member 25b. One side of the second inclined member 24b may be coupled to the connection member 22b, and the other side thereof may be coupled to the limiting member 25b. The second inclined member 24b may be coupled to the connection member 22b in a direction opposite to the direction in which the first inclined member 23b is coupled to the connection member 22b. For example, when the first inclined member 23b is located in the first direction (FD arrow direction) with respect to the connecting member 22b, the second inclined member 24b is in relation to the connecting member 22b. It may be coupled to the connection member 22b in the second direction (SD arrow direction). The second inclined member 24b may be formed to be inclined so as to decrease in height toward the connecting member 22b from the fixing member 21b.

The limiting member 25b is connected to the support contact 2e as the connection member 22b is connected to the card C, thereby moving the connection member 22b in the downward direction (DD arrow direction). You can limit the distance. As shown in FIG. 9, the support contact 2e is located below the fixing member 21b to limit the distance that the connection member 22b moves in the downward direction (DD arrow direction). .

The included angle θ2 between the second inclined member 24b and the substrate 100 may be greater than the included angle θ1 between the first inclined member 23b and the substrate 100. . Accordingly, the card connector 1 according to the present invention can reduce the length increase in the second axis direction (Y-axis direction).

As described above, in the card connector 1 according to the present invention, one side of the second contact 2b is coupled to the second insulating body 30b and the other side extends toward the second direction (SD arrow direction). And overlap the first insulating body 30a and are coupled to the second card C2 at the same height as the third contact 2c coupled to the second insulating body 30b. As described above, in order for the second contact 2b to be coupled to the second card C2 at the same height as the third contact 2c, the connection member 22b is lowered by the limiting member 25b. The distance traveled in the direction (DD arrow direction) should be limited. At this time, the comparative angle θ2 between the second inclined member 24b and the substrate 100 is smaller than or equal to the included angle θ1 between the first inclined member 23b and the substrate 100. According to the second axial direction (2) of the second inclined member (24b) by forming the second inclined member (24b) to a length that can be connected to the support contact (2e) Y-axis direction) there is a limit to reduce the length.

Accordingly, in the card connector 1 according to the present invention, the included angle θ2 between the second inclined member 24b and the substrate 100 is between the first inclined member 23b and the substrate 100. Since it is formed to have a value larger than (θ1), the increase in the length of the second inclined member 23b in the second axial direction (Y-axis direction) is reduced, and the second axial direction (Y-axis direction) is used as a reference. To reduce the overall length.

In addition, the length L1 of the first inclined member 23b may be formed to have a length 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 for the second contact 2b by reducing the plastic deformation occurring in the first inclined member 23b, thereby increasing the elastic displacement. Through this, the connection force between the connection member 22b and the card C may be further increased.

Looking at these effects in detail as follows. The length of the first inclined member 23b and the length of the second inclined member 24b are summed so as to reduce the length of the second contact 2b based on the second axial direction (Y-axis direction). The value should be designed not to exceed a predetermined value. Meanwhile, according to a comparative example in which the length L1 of the first inclined member 23b is less than or equal to the length L2 of the second inclined member 24b, the connection member 22b and the card C are formed. ), The service life of the second contact (2b) is shortened by the plastic deformation occurring in the first inclined member (23b) as the connection between the two. Therefore, the board connector 1 according to the present invention is formed by the first inclined member 23b has a longer length than the second inclined member 24b, thereby preventing plastic deformation occurring in the first inclined member 23b. It can reduce and increase elastic displacement.

The lower surface of the lower support member 40a may be positioned toward the lower direction (DD arrow direction) with respect to the lower surface 102 of the substrate 100 based on the third axis direction (Z-axis direction). Accordingly, the card connector 1 according to the present invention has the contact on the upper side of the lower support member 40a positioned at a height at which at least one of the cards C of the tray 10 overlaps the substrate 100. Since it is implemented to be connected to any one of (2), it is possible to reduce the height protruding from the upper surface 101 of the substrate 100.

The side wall 45 is for connecting the lower support member 40a and the lower mounting member 41. The side wall 45 may be located between the lower support member 40a and the lower mounting member 41 with respect to the third axial direction (Z-axis direction).

10 and 11, the side wall 45 may include a left wall 45a and a right wall 45b.

Can be. The left wall 45a and the right wall 45b are disposed to be spaced apart from each other based on the first axis direction (X-axis direction). The lower support member 40a is positioned between the left wall 45a and the right wall 45b with respect to the first axial direction (X-axis direction). The left side wall 45a and the right side wall 45b may each be formed in a rectangular parallelepiped shape. In the card connector 1 according to the present invention, the lower support member 40a is connected to the lower surface DD of the substrate 100 through the left side wall 45a and the right side wall 45b. And the lower mounting member 41 may be mounted on the substrate 100 on the upper surface 101 of the substrate 100. Accordingly, in the card connector 1 according to the present invention, the lower shell body 40 may be more firmly supported against external forces such as vibration and shaking.

The lower mounting member 41 may be coupled to at least one of the left side wall 45a and the right side wall 45b to be mounted on the substrate 100. When the lower mounting members 41 are formed to be spaced apart from each other along the first axial direction (X-axis direction), the lower mounting members 41 are respectively formed on the left side wall 45a and the right side wall 45b. Can be combined. When the lower mounting members 41 are formed to be spaced apart from each other along the second axial direction (Y-axis direction), the lower mounting members 41 may be any one of the left side wall 45a and the right side wall 45b. All can be combined in one. 10 and 11, the card connector 1 according to the embodiment of the present invention is spaced apart from each other along the first axial direction (X-axis direction) and the second axial direction (Y-axis direction). By including four lower mounting members 41 disposed, the lower shell 4 may be stably coupled to the substrate 100. However, the present invention is not limited thereto and may include five or more lower mounting members 41.

The front wall 45c and the rear wall 45d may protrude from the lower support member 40a toward the upper direction (UD arrow direction). The front wall 45c and the rear wall 45d are formed to protrude from the edge parallel to the first axial direction (X-axis direction) of the lower support member 40a toward the upper direction (UD arrow direction). Can be. The front side wall 45c and the rear side wall 45d are disposed to be spaced apart from each other based on the second axial direction (Y-axis direction). The lower support member 40a is positioned between the front side wall 45c and the rear side wall 45d with respect to the second axial direction (Y-axis direction). The front side wall 45c and the rear side wall 45d may each be formed in a rectangular parallelepiped shape. The card connector 1 according to the present invention reinforces the bending strength of the lower support member 40a through the front side wall 45c and the rear side wall 45d so that the lower support member 40a is the third shaft. It can prevent bending in the direction (Z-axis direction). Accordingly, the card connector 1 according to the present invention can improve the connection reliability between the cards (C) accommodated in the tray 10 and the contacts (2).

Specifically, the insulator which supports the contacts 2 as the tray 10 is inserted into the coupling groove 31 so that the cards C of the tray 10 are connected to the contacts 2. The pressure is generated at (3), and the pressure is also transmitted to the lower shell (4) supporting the insulator (3). Accordingly, pressure is applied to the lower support member 40a toward the lower direction (DD arrow direction), thereby causing a full stomach phenomenon toward the lower direction (DD arrow direction).

Accordingly, the card connector 1 according to the present invention has the front wall 45c formed in the first axial direction (X-axis direction) perpendicular to the third axial direction (Z-axis direction) in which a full stomach phenomenon occurs. By reinforcing the bending strength of the lower support member 40a through the rear wall 45d), it is possible to prevent the lower support member 40a from bending in the lower direction (DD arrow direction).

On the other hand, the tray 10 is inserted into the coupling groove 31 so that the card C of the tray 10 is connected to the contacts 2 to support the contacts 2. When pressure is generated in 3), the pressure is also transmitted to the upper shell 5 located on the upper side (UD arrow direction) side of the insulator 3. Accordingly, pressure is applied to the upper shell 5 toward the upper direction (UD arrow direction), so that a phenomenon of filling may occur toward the upper direction (UD arrow direction).

The upper shell 5 may include the upper mounting member 51 formed in a greater number than the lower mounting member 41 so as to prevent such a full stomach phenomenon. Specifically, since the upper shell 5 should be able to be coupled to both the first insulating body 30a and the second insulating body 30b, the lower shell (only coupled to the first insulating body 30a) 4) It can be formed with a larger area. Accordingly, the card connector 1 according to the present invention allows the upper mounting member 51 to be formed in a greater number than the lower mounting member 41, so that the area mounted on the substrate 100 is broadly provided. It is possible to prevent the upper shell 5 from bending in the upward direction (UD arrow direction).

The front side wall 45c may have a length shorter than the bottom surface 300 (shown in FIG. 6) of the first insulating body 30a based on the third axis direction (Z-axis direction). The front wall 45c may protrude from the lower support member 40a to a height lower than a height at which the bottom surface 300 of the first insulating body 30a is formed. As the height of the front side wall 45c is formed to be lower than the height of the bottom surface 300 of the first insulating body 30a, the board connector 1 according to the present invention is the tray 10 is the coupling groove ( 31 may be prevented from being disturbed by the front wall 45c during insertion. The rear side wall 45d may have the same length as the front side wall 45c with respect to the third axial direction (Z-axis direction). The rear side wall 45d may be formed to have a longer length than the front side wall 45c with respect to the third axial direction (Z-axis direction). For example, the rear side wall 45d may protrude from the lower support member 40a to a height higher than the height at which the bottom surface 300 of the first insulating body 30a is formed. That is, since the rear wall 45d does not interfere with the tray 10 inserted into the coupling groove 31, the rear wall 45d is formed to have a length longer than that of the front wall 45c, so that the bending strength of the lower support member 40a is increased. The improvement effect can be increased.

As shown in FIG. 10, the left side wall 45a, the right side wall 45b, the front side wall 45c, and the rear side wall 45d are bent plate materials including the lower support member 40a.

Accordingly, the card connector 1 according to the present invention may allow the contacts 2 and the substrates to electrically connect the cards C and the substrate 100 respectively accommodated in the tray 10 at different heights. By implementing the insulating part 3, miniaturization can be implemented and thus can be applied to miniaturized electronic devices.

Second, the card connector 1 according to the present invention is implemented so that the lower shell body 40 is protruded to the lower side of the substrate 100 through the cutting groove (S) formed in the substrate (100) It is possible to implement a low magnification by reducing the height formed on the upper side of 100). That is, according to a comparative example in which all the cards C are inserted into the card connector while the cards C are disposed along the third axis direction (Z-axis direction), the card connector may include the card connector. The upper shell 5 is formed at a height close to twice the height 5H protruding from the upper surface 101 of the substrate 100. Therefore, the card connector 1 according to the present invention is implemented so as to protrude to the lower side of the substrate 100 while the lower shell 4 is inserted into the cutting groove (S), the upper and lower sides of the substrate 100 This can reduce the overall height projecting.
