That is, in order to shield the electromagnetic wave radiated from the second contact 220, the outer shield wall 233 may be formed to cover the second contacts 220. In this case, as shown in FIGS. 12 to 14, the outer shield wall 233 may be positioned to be spaced apart from the substrate connection portion C2 in the width direction X by a second set interval D2 or more. That is, when comparing the length (DC) of one end to which the second contact 220 is exposed and the distance DD between the second contact 220 and the outer shield wall 231, the outer shield wall 233 This may be formed to be further spaced apart by at least the second set interval D2.

The bridge 233A may be connected from the outer wall protection portions 232A and 232B, and may extend in the width direction X. Here, the length of the bridge 233A may be determined according to the size of a counterpart into which the plug connector 200 is inserted. However, the length of the bridge 233A is determined so that the shield wall portion 233B connected to the bridge 233A is spaced apart from the substrate connection portion C2 of the second contact 220 in the width direction by at least the second set distance D2.

In addition, according to an exemplary embodiment, the flat body connected to the bridge 233A is bent in the direction of the body part 211, and the shield wall part 233B may have an inverted U-shaped cross section. Here, when the cross section of the shield wall portion 233B is implemented in an inverted U shape, it is possible to increase the fastening strength when combined with the substrate, and to increase the effect of the electromagnetic shielding function.

Additionally, the shape of the inverted U-shaped shield wall portion 233B can prevent damage to the outer shield wall 233 that may occur when fastening with the receptacle connector 100, as shown in FIG. 16. For example, even when the plug connector 200 is forcibly inserted into the receptacle connector 100 in a misaligned state, the plug connector 200 may be guided by the inverted U shape of the shield wall portion 233B. . Therefore, even during abnormal fastening, it is self-aligned by an inverted U-shape, so that it can be accurately fastened.

Depending on the embodiment, it is also possible to implement the thickness of the flat body thinner than the thickness of the bridge (233A).

Additionally, the second set height H2 of the shield wall portion 233B may be set to be less than or equal to the height HA of the second contacts 220 as shown in FIG. 14. If, when the second set height H2 of the shield wall part 233B is higher, excessively strong pressure may be applied to the shield wall 233B during abnormal fastening, resulting in damage to the outer shield wall 233. Such problems may occur. Therefore, by setting the second set height H2 of the shield wall part 233B to be less than or equal to the height HA of the second contact 220, the contact parts 120 and 220 of each connector when combined with the receptacle connector 200 You can make them contact first. That is, by distributing the pressure applied during insertion to each of the contact portions 120 and 220, a load that may be applied to the outer shield wall 233 can be minimized.

Meanwhile, the shield wall portion 231B may include a plurality of openings A2 penetrating the shield wall portion 231B in the width direction X.

In addition, the shield wall portion 233B may include a plurality of protrusions B2 separated by an opening A2, as shown in FIGS. 10 to 12, wherein each protrusion B2 is grounded on the substrate. Can be connected. That is, since the point connected to the ground can be increased, the electric shielding effect by the outer shield wall 230 can be increased.

Additionally, the shield wall portion 231B may further include a fixing portion L bent in an L-shape at an end portion in the longitudinal direction (Y). Here, since the fixing part L is implemented in an L-shape, it is possible to sufficiently secure an area for soldering. Accordingly, by fixing the fixing portion L on the substrate by soldering, it is possible to enhance the fastening strength of the shield wall portion 231B to the substrate. In particular, the fixing part L may reinforce a fastening force corresponding to an external force in the longitudinal direction Y.

That is, each of the contact protection portions 134 and the shield wall portion 233B is in the width direction (x-axis). Direction) apart from each other, it is possible to reduce the width size of the combined connector modules compared to the case where they do not overlap.

In addition, the first set height H1 of the contact protection part 134 and the second set height H2 of the shield wall part 233B may be divided from a preset total fastening height. That is, the sum of the first set height H1, the second set height H2, and the buffer height (not shown) may be set to be the total fastening height. In this case, it is possible to minimize the length in the thickness direction despite the overlapping of the contact protection part 134 and the shield wall part 233B.

Additionally, the receptacle connector 100 and the plug connector 200 according to an embodiment of the present invention may further include a structure for enhancing fastening force. Specifically, as shown in FIGS. 16 and 17, the inner wall protection portion 131 or the outer wall protection portion 133 of the receptacle connector 100 may include a protrusion P, and the plug connector 200 Each insertion groove (Q) may be included in a position corresponding to the protrusion (P). That is, the protrusion P of the receptacle connector 100 is inserted into the insertion groove Q, so that the fastening force between the plug connector 200 and the receptacle connector 100 can be increased. Here, the insertion groove (Q) may be formed through coining or the like.

18 is an EMI (Electro Magnetic Interference) shielding performance according to the presence or absence of the receptacle shield unit 130 and the plug shield unit 230 with respect to the receptacle connector 100 and the plug connector 200 according to an embodiment of the present invention. It is a schematic diagram showing the experimental results of each experiment.

18(a) is an experiment result showing the EMI shielding performance when the receptacle shield part 130 and the plug shield part 230 are provided. When the receptacle connector 100 and the plug connector 200 are coupled, dark blue portions on both sides indicate that the electric field is low, indicating that electromagnetic wave blocking is well performed.

On the other hand, FIG. 18(b) is a comparative example, and corresponds to a case where the receptacle shield part 130 and the plug shield part 230 are not provided in the receptacle connector 100 and the plug connector 200, respectively. Here, when the receptacle connector 100 and the plug connector 200 are coupled, both sides are shown in light blue, which means that the electric field is relatively high compared to dark blue. That is, when the receptacle connector 100 and the plug connector 200 are not provided with the receptacle shield unit 130 and the plug shield unit 230, respectively, it indicates that electromagnetic wave blocking is not well performed.

The present invention is not limited by the above-described embodiments and the accompanying drawings. It will be apparent to those of ordinary skill in the art to which the present invention pertains, that components according to the present invention can be substituted, modified, and changed within the scope of the technical spirit of the present invention.
