[0059] like Figures 1 to 15As shown, according to the first aspect of the embodiment of the utility model, a shielding assembly 10 is proposed, which is applied to a display device 100. The display device 100 includes a circuit board 20, and the shielding assembly 10 includes a shielding cover 11, a connector 30 and a plug connector 12. The shielding cover 11 is arranged on the circuit board 20; the shielding cover 11 includes a top wall 113 and a side wall 112 connected to each other, the top wall 113 and the side wall 112 form an installation cavity, and the end of the side wall 112 facing the circuit board 20 forms a first opening 111, the first opening 111 is a rectangular opening, and when the side wall 112 is installed on the circuit board 20, the first opening 111 is closed by the circuit board 20, and a second opening 1134 and a first matching structure are provided on the top wall 113, and the first matching structure is arranged at the second opening 1134 Along one side of the first direction, the first opening 111 and the second opening 1134 are both connected to the installation cavity; a third opening 1125 is provided on the side wall 112, and the third opening 1125 is connected to the second opening 1134; the connector 30 is arranged on the circuit board 20 and is located in the installation cavity; the plug connector 12 includes a connecting portion 121, and a second matching structure matching the first matching structure is provided on the connecting portion 121, and at least part of the connecting portion 121 is arranged in the installation cavity in a detachable manner, wherein the connecting portion 121 can be taken out from one side of the third opening 1125, and at least part of the connecting portion 121 is electrically connected to the connector 30, and the second matching structure and the first matching structure are matched in a concave-convex manner, so that at least part of the connecting portion 121 can be arranged in the installation cavity in an expected state and electrically connected to the connector 30.

[0060] It should be noted that the installation cavity here is a cavity that can play a shielding role, and the connector 30 is located in the installation cavity, which can reduce the radio frequency interference generated by the connector 30. In addition, the first matching structure and the second matching structure here are concave-convex matching, which means that the first matching structure and the second matching structure are respectively a convex and concave matching structure, which can play a matching role in the YY direction, so that the connecting portion 121 can only be led out of the installation cavity from the third opening 1125, reducing the probability of reverse insertion of the plug connector 12. Among them, the first matching structure can be a convex structure, and the second matching structure is a concave structure, or the first matching structure is a concave structure, and the second matching structure is a convex structure.

[0061] The plug connector 12 here has an expected state and an unexpected state when installed in the installation cavity, wherein the expected state is positive insertion, at this time, the connecting part 121 can be led out from the position of the third opening 1125, and the unexpected state is reverse insertion, at this time, the connecting part 121 can be led out from the position away from the third opening 1125, which can easily cause the connector 30 to be burned.

[0062] According to the shielding assembly 10 of the utility model, a first matching structure is arranged on the top wall 113, and a second matching structure matching with the first matching structure is arranged on the connecting portion 121 of the plug connector 12, wherein the second matching structure and the first matching structure can be matched in a concave-convex manner, and at least a part of the connecting portion 121 can be arranged in the installation cavity in an expected state and electrically connected to the connector 30. Then, when the plug connector 12 is placed in the installation cavity, the connecting portion 121 can only be arranged in the installation cavity in an expected state, thereby reducing the probability of the plug connector 12 being reversely inserted into the shielding cover 11, thereby reducing the probability of the connector 30 being burned.

[0063] In addition, the shielding cover 11 here is a box-shaped structure, and the end of the box-shaped structure facing the circuit board 20 forms a first opening 111. At this time, the first opening 111 is set close to the circuit board 20. The shielding cover 11 can specifically be a rectangular box-shaped structure or a circular box-shaped structure. Of course, it can also be a box-shaped structure of other shapes.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, the following description will be made based on the shielding cover 11 being a rectangular box-shaped or trapezoidal box-shaped structure. The side wall 112 includes a first wall 1121, a second wall 1122, a third wall 1123 and a fourth wall 1124 connected end to end in sequence, and the four walls enclose a mounting cavity of a trapezoidal space or a rectangular space, wherein the first wall 1121 and the third wall 1123 are arranged at intervals along the XX direction, and the second wall 1122 and the fourth wall 1124 are arranged at intervals along the second direction YY, wherein the third opening 1125 is arranged on the fourth wall 1124 and communicates with the second opening 1134, wherein the fourth wall 1124 is located on one side of the shielding cover 11 along the second direction YY. The first wall 1121, the second wall 1122, the third wall 1123 and the fourth wall 1124, one end facing the circuit board 20, enclose a first opening 111, wherein the first opening 111 is arranged in the direction of the circuit board 20. The second opening 1134 is disposed opposite to the first opening 111 , wherein the second opening 1134 is formed on the top wall 113 , and the depth direction of the third opening 1125 is the same as the second direction YY.

[0065] Alternatively, if Figure 1 , Figure 2 and Figure 3As shown, the top wall 113 further includes a first reinforcing rib 1131 and a second reinforcing rib 1132, the first reinforcing rib 1131 and the second reinforcing rib 1132 are respectively arranged at both ends of the top wall 113 along the first direction, and a second opening 1134 is formed between the first reinforcing rib 1131 and the second reinforcing rib 1132, wherein at least one of the first reinforcing rib 1131 and the second reinforcing rib 1132 is provided with a first matching structure; wherein the first direction is intersected with the depth direction of the third opening 1125, wherein the first direction is Figure 1 XX direction in the.

[0066] It should be noted that the first matching structure here can be one, or two or more. When the first matching structure is one, it can be set on the first reinforcing rib 1131 or on the second reinforcing rib 1132. When the first matching structure is two or more, the first matching structure is set on both the first reinforcing rib 1131 and the second reinforcing rib 1132.

[0067] The utility model provides a first matching structure on at least one of the first reinforcing rib 1131 and the second reinforcing rib 1132. Therefore, when the connecting portion 121 of the plug connector 12 is placed into the installation cavity through the second opening 1134, a fool-proof design can be formed through the concave-convex matching of the first matching structure and the second matching structure, thereby reducing the probability of the connecting portion 121 being reversely inserted, thereby reducing the situation in which the connector 30 is burned due to electrical connection with the connector 30 after the connecting portion 121 is reversely inserted.

[0068] Continue to refer to Figures 1 to 6 As shown, a first matching structure is provided on the first reinforcing rib 1131 or the second reinforcing rib 1132, and a second matching structure matching the first matching structure is correspondingly provided on the connecting portion 121. Figure 3 In the embodiment, the first matching structure is a notch structure, and the number of the first matching structure is one, which is formed on the first reinforcing rib 1131. Of course, the first matching structure here can also be formed on the second reinforcing rib 1132, which will not be described here.

[0069] It should be noted that the number of the first matching structure and the number of the second matching structure are both one, which can facilitate the installation of the connecting part 121 in the installation cavity and can serve as a fool-proof design. It can not only facilitate the operator to identify the direction, but also prevent the connecting part 121 from contacting the connector 30 when it is reversely inserted, thereby reducing the probability of electrical connection between the connecting part 121 and the connector 30.

[0070] The connector 30 here may be a double-row connector 30 or a single-row connector 30 , and a conventional connector 30 may be used.

[0071] In addition, it should be noted that a plurality of connection terminals are provided on the surface of the connection portion 121 facing the connector 30 , and the connection of the circuit is achieved through the electrical connection between the connection terminals and the connector 30 .

[0072] Continue to refer to Figures 1 to 6 As shown, the connecting portion 121 is a rectangular plate-shaped structure, and the second matching structure is disposed at one end of the connecting portion 121 along the first direction XX, and the second matching structure is flush with the connecting portion 121 or the second matching structure is spaced apart from the end of the connecting portion 121 facing the shielding cover 11. Figure 1 In the figure, the second matching structure is flush with the connecting portion 121, and the gap between the second matching structure and the end of the connecting portion 121 facing the shielding cover 11 is zero. Of course, the second matching structure and the end of the connecting portion 121 facing the shielding cover 11 may also have a gap. In this case, the position of the first matching structure can be adjusted accordingly.

[0073] Specifically, the end of the connection part 121 facing the shielding cover 11, that is, the end of the connection part 121 close to the shielding cover 11 along the second direction YY, the second matching structure here can be flush with the end of the connection part 121 close to the shielding cover 11, or it can be in a non-flush state with the end of the connection part 121 close to the shielding cover 11, with a gap. Figure 7 As shown, the second matching structure on the left is flush with the end of the connecting portion 121 close to the shielding cover 11 , and the second matching structure on the right is spaced apart from the end of the connecting portion 121 close to the shielding cover 11 .

[0074] In some embodiments of the present invention, the second matching structure is a rectangular plate structure. Of course, the second matching structure here can also be a circular plate structure or a plate structure of other shapes, which can form a concave-convex match with the first matching structure.

[0075] Among them, Figure 1 As shown, the second matching structure is a rectangular protrusion structure, the dimension of the second matching structure along the XX direction is L2, the dimension along the YY direction is H, and the dimension of the second reinforcing rib 1132 along the XX direction is L1, wherein the conventional dimension of L1 is about 2.1 mm, the dimension of L2 is about 1.38 mm, and H is about 5.1 mm. Of course, the dimensions here can also be changed according to the size of the installation cavity.

[0076] In the present invention, the second matching structure is configured as a rectangular plate-shaped structure, which can facilitate processing and increase the connection strength with the connecting portion 121 .

[0077] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the top wall 113 also includes a first interference portion 1133, the first interference portion 1133 is connected to the side wall 112, and the two ends of the first interference portion 1133 along the first direction are respectively connected to the first reinforcement rib 1131 and the second reinforcement rib 1132; the second matching structure is a convex structure, the first matching structure is a concave structure, and at least part of the second matching structure can be accommodated in the first matching structure.

[0078] In the present invention, although the first interference portion 1133 can also play a certain foolproof design, in the case of reverse insertion of the connection portion 121, the connection portion 121 can be placed in the installation cavity and contact the connector 30, resulting in the situation of burning the connector 30. Therefore, in addition to the first interference portion 1133, the present invention also provides a first matching structure and a second matching structure, and at least part of the second matching structure can be accommodated in the first matching structure, thereby increasing the foolproof structure and reducing the probability of reverse insertion of the connection portion 121.

[0079] Alternatively, if Figures 1 to 5 As shown, the first matching structure is the first notch 1135, and the second matching structure is the first protrusion 1211, wherein the first notch 1135 is arranged on the first reinforcing rib 1131, and the first reinforcing rib 1131 includes a first plate body and a second plate body that are intersected and connected, wherein the first plate body and the second plate body form an L-shaped structure, and the first plate body and the first interference portion 1133 are connected; when the first protrusion 1211 is accommodated in the first notch 1135, there is a first interval W1 between the first protrusion 1211 and the first interference portion 1133, there is a second interval W2 between the first protrusion 1211 and the first plate body, there is a third interval W3 between the first protrusion 1211 and the second plate body, and at least two of the first interval W1, the second interval W2 and the third interval W3 are the same, wherein the first plate body extends along the YY direction, and the second plate body extends along the XX direction.

[0080] The first interval W1, the second interval W2 and the third interval W3 can be the same, such as about 0.4 mm, etc. Of course, other sizes can also be selected.

[0081] Alternatively, if Figures 7 to 15 As shown, the first reinforcing rib 1131 and the second reinforcing rib 1132 are respectively provided with a first matching structure; two second matching structures are provided on the connecting portion 121, and the two second matching structures are respectively arranged on both sides of the connecting portion 121 along the first direction, and when the connecting portion 121 is in the expected state, the two second matching structures are respectively adapted to the corresponding first matching structures.

[0082] It should be noted that the second matching structure and the corresponding first matching structure here are adapted to each other, which means that the second matching structure and the first matching structure have the same shape and are relatively close in size, so that the first matching structure and the second matching structure can form an anti-foolproof structure. For example, when the first matching structure is a rectangular hole, the second matching structure is a rectangular protrusion; conversely, if the first matching structure is a semicircular hole, the second matching structure is a semicircular protrusion. In addition, the size of the second matching structure is slightly smaller than the first matching structure, so that a concave-convex matching structure is formed between the second matching structure and the first matching structure, thereby achieving an anti-foolproof effect.

[0083] In the present invention, by providing two second matching structures and two first matching structures that match each other in a concave and convex manner, a foolproof structure can be formed from more positions, reducing the probability of reverse connection of the connection part 121. When the connection part 121 is in a reverse insertion state, the connection part 121 will not be electrically connected to the connector 30.

[0084] Optionally, the two second matching structures are respectively a first protrusion 1211 and a second protrusion 1212, wherein the first protrusion 1211 is a rectangular plate-shaped structure, and the second protrusion 1212 is a rectangular plate-shaped structure. Of course, the first protrusion 1211 here can also be set as a semicircular plate-shaped structure or other shapes, and the second protrusion 1212 can also be set as a semicircular plate-shaped structure or other shapes.

[0085] The shapes of the first protrusion 1211 and the second protrusion 1212 may be the same or different. In addition, the size of the first protrusion 1211 and the size of the second protrusion 1212 may be the same or different.

[0086] exist Figure 7 In the figure, the first protrusion 1211 and the second protrusion 1212 are arranged in an asymmetric structure on both sides of the connecting portion 121 along the XX direction, wherein the first protrusion 1211 is arranged flush with the connecting portion 121, and there is a gap between the end of the second protrusion 1212 facing the third opening 1125 and the end of the connecting portion 121 facing the third opening 1125, and accordingly, two matching first notches 1135 and second notches 1136 are respectively arranged on the first reinforcing rib 1131 and the second reinforcing rib 1132, wherein the first notch 1135 and the second notch 1136 are also arranged in an asymmetric manner.

[0087] exist Fig.10In the figure, the first protrusion 1211 and the second protrusion 1212 are arranged on both sides of the connecting portion 121 along the XX direction in an asymmetric structure, wherein the first protrusion 1211 is arranged flush with the connecting portion 121, and the second protrusion 1212 is also arranged flush with the connecting portion 121. Correspondingly, two matching first notches 1135 and second notches 1136 are respectively arranged on the first reinforcing rib 1131 and the second reinforcing rib 1132, wherein the first notch 1135 and the second notch 1136 are also arranged in an asymmetric manner.

[0088] exist Fig.13 In the figure, the first protrusion 1211 and the second protrusion 1212 are symmetrically arranged on both sides of the connecting portion 121 along the XX direction, wherein the first protrusion 1211 is flush with the connecting portion 121, and the second protrusion 1212 is also flush with the connecting portion 121. Correspondingly, two matching first notches 1135 and second notches 1136 are respectively arranged on the first reinforcing rib 1131 and the second reinforcing rib 1132, wherein the first notch 1135 and the second notch 1136 are also symmetrically arranged.
