Description

Technical Field

[0001] The invention relates to an electrical connector assembly. Background Art

[0002] As connectors are becoming increasingly miniaturized, the spacing between terminals is further reduced, or crosstalk and signal interference are easily generated during implementation, making it difficult to apply them to applications with high-frequency requirements. In particular, at present, there is still no effective EMI prevention mechanism for high-frequency signal interference in flat cable connectors such as FPC, which needs to be improved or resolved.

[0003] Furthermore, under the aforementioned trend of miniaturization, the existing connectors are often combined by overlapping the connector and the flat cable. However, when installing the connector, the user will be in a blind insertion state because the user's vision is blocked by the flat cable, which makes assembly difficult and takes a long time. Summary of the invention

[0004] The invention provides an electric connector assembly, which can provide the effect of resisting signal interference and is easy to assemble.

[0005] The electrical connector assembly of the present invention comprises an electrical connector, at least one connector and at least one metal cover. The connector is disposed and electrically connected to the electrical connector. The metal cover is disposed on the electrical connector. The electrical connector is located between the connector and the metal cover, and the connector is shielded by the electrical connector.

[0006] In some embodiments, the electrical connector is a flexible printed circuit board (FPC) or a rigid printed circuit board.

[0007] In some embodiments, the electrical connector has at least one grounding portion, and the metal cover covers and is electrically connected to the grounding portion.

[0008] In some embodiments, the electrical connector assembly described above is a board-to-board connector assembly.

[0009] In some embodiments, the orthographic projection profile of the connector on the electrical connector is located inside the electrical connector.

[0010] In some embodiments, the metal cover has at least one combining structure.

[0011] In some embodiments, the metal cover further comprises a main body and a plurality of side skirts, wherein the side skirts are extended and bent from the main body.

[0012] In some embodiments, the connector is adapted to dock with another connector on a circuit board, and the metal cover is assembled on the circuit board to cover the docked connectors. The bonding structure is at least one of the side skirts. The circuit board also has a conductive structure and another grounding portion for the conductive structure to be configured. When the metal cover is assembled on the circuit board, the bonding structure is disposed on the conductive structure, and the metal cover is electrically connected to the other grounding portion through the bonding structure and the conductive structure.

[0013] In some embodiments, the above connector is suitable for docking with another connector on the circuit board, and the metal cover is assembled on the circuit board to cover the docking connectors. The above-mentioned coupling structure is a locking portion extending from the side skirt. The circuit board also has a locking hole and another grounding portion, and the other grounding portion is located in the locking hole. The locking attachment is suitable for passing through the locking portion and being coupled to the locking hole and connected to the other grounding portion, and the metal cover is electrically connected to the other grounding portion through the locking portion and the locking attachment.

[0014] In some embodiments, the electrical connection assembly further includes at least one guide member extending from the side skirt, and the guide member is placed in a guide hole defined on the circuit board.

[0015] Based on the above, the electrical connector assembly is configured by placing a metal cover on the electrical connector, and the orthographic projection of the connector on the electrical connector is located within the range of the orthographic projection of the metal cover on the electrical connector, that is, the connector is substantially fixed below the metal cover, that is, the relative position between the two is fixed. In this way, when the connector of the electrical connector assembly is to be docked with another electrical connector, the user can use the metal cover as an assembly target to avoid blind insertion. Furthermore, the metal cover can also provide a signal shielding effect for the connectors that are docked with each other, especially when performing high-speed signal transmission, it can effectively improve the interference of electromagnetic interference (EMI) or radio frequency interference (RFI).

[0042] Figure 1 is an exploded view of an electrical connector assembly according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the electrical connector assembly after assembly from another perspective. Please also refer to Figure 1 and Figure 2 In this embodiment, the electrical connector assembly 100 includes an electrical connector 110, at least one connector and at least one metal cover. A pair of connectors 114A, 114B and a pair of metal covers 120A, 120B are illustrated as examples. However, as shown in the figure, the connector 114A and the metal cover 120A on one side and the connector 114B and the metal cover 120B on the other side substantially have the same configuration structure. Therefore, the status of the other side can be known only from the connector 114A and the metal cover 120A on one side.

[0043] In this embodiment, the electrical connector 110 is, for example, a flexible printed circuit (FPC), and the connectors 114A and 114B are respectively disposed on opposite sides of the electrical connector 110, and a plurality of lines 112a are electrically connected between the connectors 114A and 114B, so that the electrical connector assembly 100 is regarded as a board-to-board connector assembly, so that the user can use it as an electrical connection interface between two different electronic devices (for example, two different circuit boards). In another embodiment not shown, the electrical connector can also be a hard circuit board (for example, a multi-layer printed circuit board).

[0044] Please refer to Figure 1 The electrical connector 110 also has at least one grounding portion (herein, multiple grounding portions 112b are used as an example), which is located on the upper surface of the carrier 112 and is electrically connected to the grounding of the circuit 112a. When the metal covers 120A and 120B are arranged and covered on the upper surface of the carrier 112 of the electrical connector 110, the metal covers 120A and 120B will cover and electrically connect these grounding portions 112b. In other words, the multiple groundings of the circuit 112a can be electrically connected to the metal covers 120A and 120B, thereby achieving the effect of uniform grounding potential.

[0045] The connection relationship between the metal covers 120A, 120B and the carrier 120 of the electrical connector 110 is not limited here. They are fixed together by, for example, conductive adhesive bonding, tin welding or laser welding, and the grounding portion 112b and the metal covers 120A, 120B can also achieve electrical conduction through the above-mentioned connection means.

[0046] As mentioned above, in order to meet the trend of miniaturization, Figure 1 , Figure 2 As shown, the carrier 112 of the electrical connector 110 forms an eave structure at its two opposite ends, and the connectors 114A and 114B are arranged under the eave structure. However, since the sight is blocked during assembly, the metal covers 120A and 120B are required as replacement targets. Figure 3 This is a schematic diagram of the connection between a portion of an electrical connector assembly and another connector. Figure 2 and Figure 3 When the metal covers 120A, 120B are combined with the electrical connector 110, the electrical connector 110 is substantially located between the connector 114A or 114B and the metal cover 120A or 120B, and the orthographic projection of the connector 114A or 114B on the electrical connector 110 is within the range of the orthographic projection of the metal cover 120A or 120B on the electrical connector 110. In other words, although the connector 114A or 114B will be shielded by the metal cover 120A, 120B and the connector 114A, 114B cannot be directly seen during assembly, this also enables the present embodiment to use the metal cover 120A, 120B as the assembly target. The reason for this is that after being combined with the electrical connector 110, the metal cover 120A, 120B will have a fixed relative position with the corresponding connector 114A, 114B, allowing the user to complete the docking action directly through the metal cover 120A, 120B when docking the connectors.

[0047] For more details, please refer to Figure 3 , here taking the docking of the connector 114A and the connector 230 on the circuit board 200A as an example, in this embodiment, the metal cover 120A has a main body 122 and a plurality of side skirts 124a, 124b, and the side skirts 124a, 124b are extended and bent from the main body 122. Furthermore, the metal cover 120A also has a guide member 123 and a coupling structure, so that when the metal cover 120A is assembled on the circuit board 200A, the guide member 123 and the circuit board 200A can be aligned with each other, and the coupling structure can be used to fix the circuit board 200A together. In this embodiment, the guide member 123 extends from the side skirt 124b, and the coupling structure is a locking portion 121 extending from the side skirt 124a, and Figure 3The side skirt portion on the other side (opposite to the side skirt portion 124b) is not shown due to the viewing angle, but it also has the same guide member 123. In contrast, the circuit board 200A has guide holes 220A, 220B and a locking hole 210, which surround the connector 230 and correspond to the aforementioned guide member 123 and the locking portion 121. Accordingly, the metal cover 120A can be smoothly positioned on the circuit board 200A by matching the guide member 123 and the guide holes 220A, 220B. At the same time, the metal cover 120A can be fixed on the circuit board 200A by assembling the locking member 300 to the locking hole 210 through the locking portion 121. The assembled metal cover 120A and the circuit board 200A substantially form a closed space, and the connectors 114A and 230 that are connected to each other are located in the closed space and covered by the metal cover 120A. In this way, the required shielding effect can be provided to reduce EMI interference or RFI interference and other problems during signal transmission. At the same time, when the locking member 300 passes through the locking portion 121 and is locked into the locking hole 210, the locking member 300 is also connected to the grounding portion 240A located in the locking hole 210, and therefore the metal cover 120A is electrically connected to the grounding portion 240A of the circuit board 200A through its locking portion 121 through the locking member 300, thereby providing the required grounding effect.

[0048] Figure 4 FIG. 1 is a schematic diagram of a portion of an electrical connector assembly according to another embodiment of the present invention being docked with another connector. Figure 3 The difference between the illustrated embodiment is that in the metal cover 120C of the present embodiment, the bonding structure is the side skirt 124a, which protrudes from the carrier 112, and the circuit board 200B further has a conductive structure 250, guide holes 220C, 220D and a grounding portion 240B, wherein the conductive structure 250 is disposed on the grounding portion 240B, so that when the metal cover 120C is bonded to the circuit board 200B, the side skirt 124a of the metal cover 120C is clamped by the conductive structure 250, so that the metal cover 120C is electrically connected to the grounding portion 240B of the circuit board 200B through the side skirt 124a and the conductive structure 250. In other words, the bonding structure for assembling the metal cover 120C with the circuit board 200B in the present embodiment is the side skirt 124a of the metal cover 120C, and the conductive structure 250 presents a clamping structure that can be used to fix the side skirt 124a. The corresponding positional relationship among the guide member 123, the guide holes 220C and 220D, the side skirts 124a and 124b, and the conductive structure 250 is not limited here. In another embodiment not shown, the conductive structure 250 may be changed to correspond to the clamping side skirt 124b, and the guide member 123 may be changed to extend from the side skirt 124a.

[0049] In addition, the circuit board 200B of this embodiment further has a grounding portion 240C, which is respectively disposed in the guide holes 220C and 220D, so that when the guide member 123 is inserted into the guide holes 220C and 220D, the metal cover 120C can also be electrically connected to the grounding portion 240C through the guide member 123. It should be noted that the grounding portion 240C of this embodiment can also be disposed Figure 3 The guide holes 220A and 220B in the embodiment are used to achieve the same grounding effect.

[0050] Figure 5 FIG. 1 is a schematic diagram of the connection between an electrical connector assembly and a connector according to another embodiment. Figure 5 ,and Figure 3 The difference between the illustrated embodiment is that the metal cover 120D only has side skirts 124a, 124b and a locking portion 121 without the aforementioned guide 123, that is, the metal cover 120D and the circuit board 200C can complete the required combination by having the locking member 300 pass through the locking portion 121 and lock into the locking hole 210. Of course, the metal cover 120D is also electrically connected to the grounding portion 240A of the circuit board 200C through its locking portion 121 and the locking member 300, thereby providing the required grounding effect.

[0051] Figure 6 FIG. 1 is a schematic diagram of the connection between an electrical connector assembly and a connector according to another embodiment. Figure 6 , in the aforementioned Figure 4 The difference between the embodiments is that the metal cover 120E does not have the aforementioned guide member 123, but its side skirt 124a directly connects with the conductive structure 250 and is clamped and fixed by the conductive structure 250. Similarly, the metal cover 120E is electrically connected to the grounding portion 240B of the circuit board 200D through the side skirt 124a and the conductive structure 250.

[0052] In summary, in the above-mentioned embodiment of the present invention, the electrical connector assembly is provided with a metal cover on the electrical connector, and the orthographic projection of the connector on the electrical connector is located within the range of the orthographic projection of the metal cover on the electrical connector, that is, the connector is substantially fixed below the metal cover, that is, the relative position between the two is fixed. In this way, when the connector of the electrical connector assembly is to be connected with another electrical connector, the user can use the metal cover as the assembly target, that is, after the metal cover is assembled to the circuit board, the connector connection action can be completed at the same time, and the blind insertion situation can be avoided.

[0053] Furthermore, the metal cover can also provide signal shielding and grounding effects for the connectors that are connected to each other, and can effectively improve EMI or RFI interference during high-speed signal transmission.
