Please refer to fig. 1 and fig. 2. Fig. 1 is a schematic plan view illustrating a connection structure 100 according to a first embodiment of the invention when it is not connected. Fig. 2 is a schematic plan view illustrating the connection structure 100 according to the first embodiment of the invention after connection. The connection structure 100 includes a first connector 110 and a second connector 120. The first connector 110 includes an insulating support 111, a first conductor 112, and a second conductor 113. The first conductor 112 and the second conductor 113 are disposed on opposite sides of the insulating support 111, and have a first convex curved surface 114 and a second convex curved surface 115, respectively. The first convex curved surface 114 and the second convex curved surface 115 protrude from the insulating support 111. In some embodiments, the insulating support 111 may comprise various polymeric materials, such as polyurethane, acrylate, methacrylate, epoxy, polycarbonate, polyethylene, or polystyrene, or other suitable insulating polymeric materials. In some embodiments, the first electrical conductor 112 and the second electrical conductor 113 may be a metal or alloy or a suitable material that can form a conductive function. In a preferred embodiment, the first conductor 112 and the second conductor 113 are elastically connected to the insulating support 111, so that the first conductor 112 and the second conductor 113 can be embedded in the insulating support 111. For example, the first connector 110 may further include two springs (not shown) disposed inside the insulating support 111. The first conductive body 112 (e.g., steel ball) is connected to one of the springs, and the second conductive body 113 (e.g., steel ball) is connected to the other spring, so that the first conductive body 112 and the second conductive body 113 can be elastically connected to the insulating support 111. When the first conductor 112 and the second conductor 113 are pressed by an external force, the first conductor 112 and the second conductor 113 may be buried in the insulating support 111. However, when the external force is removed, the first conductor 112 and the second conductor 113 return to the original positions due to the elastic force of the spring. In addition, the first connector 110 also includes a first wire 160 and a second wire 170 electrically connected to the first conductor 112 and the second conductor 113, respectively. In some embodiments, the first conductive line 160 and the second conductive line 170 may be made of copper metal or other metal materials with low resistance.

The second connector 120 includes a first insulating housing 121, a second insulating housing 122, a first conductive layer 123, and a second conductive layer 124. The first insulating housing 121 and the second insulating housing 122 are respectively configured to cover all or at least a part of the first conductive body 112 and all or at least a part of the second conductive body 113. The first conductive layer 123 is disposed on the inner surface of the first insulating housing 121, and the first conductive layer 123 includes a first concave curved surface 125 matching with the first convex curved surface 114 and is configured to contact the first conductive body 112. Similarly, a second conductive layer 124 is disposed on the inner surface of the second insulating housing 122, and the second conductive layer 124 includes a second concave curved surface 126 matching with the second convex curved surface 115 and configured to contact the second conductive body 113. In some embodiments, the first and second

conductive layers

123 and 124 may be made of metal or alloy or other suitable material that can form a conductive function. In some embodiments, the first insulating housing 121 and the second insulating housing 122 may be integrally formed housings, the material of which may include various polymer materials, such as polyurethane, acrylate, methacrylate, epoxy, polycarbonate, polyethylene, or polystyrene, or other suitable insulating polymer materials. In addition, the second connector 120 also includes a third conductive line 180 and a fourth conductive line 190 electrically connected to the first conductive layer 123 and the second conductive layer 124, respectively. In some embodiments, the third conductive line 180 and the fourth conductive line 180 may be made of copper metal or other metal material with low resistance.

Referring to fig. 2, when the second connector 120 is connected to the first connector 110, the first conductor 112 and the second conductor 113 are first pressed by the second connector 120 and embedded in the insulating support 111. However, when the first conductive body 112 and the second conductive body 113 are moved to the positions of the first concave curved surface 125 and the second concave curved surface 126, respectively, the first conductive body 112 and the second conductive body 113 return to the original positions and contact the first conductive layer 123 and the second conductive layer 124, respectively. In another embodiment, the first insulating housing 121 and the second insulating housing 122 may be elastic housings, so that when the second connector 120 is connected to the first connector 110, the first connector 110 can be smoothly engaged with the second connector 120, and the first conductive body 112 and the second conductive body 113 can be contacted with the first conductive layer 123 and the second conductive layer 124, respectively.

Further, when the second connector 120 is connected to the first connector 110, the first wire 160, the first electrical conductor 112, the first conductive layer 123, and the third wire 180 form a first conductive path, and the second wire 170, the second electrical conductor 113, the second conductive layer 124, and the fourth wire 190 form a second conductive path. When the power rectifying plate R of the display 140 is electrically connected to the external power supply P, two poles of the power supply P can be respectively connected to the first conductive path and the second conductive path through the power rectifying plate R. Accordingly, the power transmitted to the display 140R is transmitted to the display 140L via the connection structure 100. In detail, one pole of the power supply P can be connected to the power rectifying board R through the conducting wire 211, and the power rectifying board R is further connected to the third conducting wire 180 of the second connector 120 through the conducting wire 221. Similarly, the other pole of the power supply P can be connected to the power rectifying board R through the conducting wire 212 and then connected to the fourth conducting wire 190 of the second connector 120 through the conducting wire 222.

It is noted that the connection structure 100 disclosed herein provides not only electrical connections, but also mechanical connections. Since the first concave curved surface 125 of the first conductive layer 123 matches with the first convex curved surface 114 of the first conductive body 112, and the second concave curved surface 126 of the second conductive layer 124 matches with the second convex curved surface 115 of the second conductive body 113, the second connector 120 and the first connector 110 can rotate relative to each other. That is, the second connector 120 is rotatably connected to the first connector 110. For example, the first convex curved surface 114 and the second convex curved surface 115 may be convex hemispheres, and the first concave curved surface 125 and the second concave curved surface 126 may be concave hemispheres, so that the second connector 120 and the first connector 110 can rotate relative to each other. In other words, the display 140R and the display 140L can rotate relative to each other due to the connection of the connection structure 100.

Please refer to fig. 3 and fig. 4. Fig. 3 is a schematic top view illustrating a connection structure 100a according to a second embodiment of the invention. Fig. 4 is a schematic cross-sectional view of the connection structure 100 a. In the second embodiment, the connection structure 100a includes a first connector 110 and a second connector 120. The first connector 110 includes an insulating support 111, a first conductor 112, and a second conductor 113. The first conductor 112 and the second conductor 113 are disposed on opposite sides of the insulating support 111. The first connector 110 of the second embodiment is different from the first embodiment in the types of the first conductor 112 and the second conductor 113. Specifically, the first electrical conductor 112 of the first connector 110 of the second embodiment includes a first rounded body 116 and a plurality of first cambered protrusions 117 protruding from the first rounded body 116. In addition, the second electrical conductor 113 includes a second rounded body 118 and a plurality of second arced protrusions 119 protruding from the second rounded body 118. Other technical features and examples of the first connector 110 of the second embodiment may be the same as any of the embodiments or examples of the first connector described above with respect to the first embodiment.

The second connector 120 of the second embodiment includes a first insulating housing 121, a second insulating housing 122, a first conductive layer 123, and a second conductive layer 124. The second connector 120 of the second embodiment is different from the first embodiment in the types of the first conductive layer 123 and the second conductive layer 124. Specifically, the first concave curved surface 125 of the first conductive layer 123 of the second embodiment includes a first rounded curved surface 127 and a plurality of first concave portions 128, and the first concave portions 128 are concave from the first rounded curved surface 127 toward the first insulating housing 121. Furthermore, the second concave curved surface 126 of the second conductive layer 124 includes a second rounded curved surface 129 and a plurality of second concave portions 130, and the second concave portions 130 are recessed from the second rounded curved surface 129 toward the second insulating housing 122. Other technical features and examples of the second connector 120 of the second embodiment may be the same as any of the embodiments or examples of the first connector described above with respect to the first embodiment.

In view of the above, the first rounded body 116 and the first cambered surface protrusion 117 of the connecting structure 100a in the second embodiment are configured to match the first rounded curved surface 127 and the first concave part 128, respectively. Further, the second rounded body 118 and the second cambered surface tab 119 are configured to match the second rounded curved surface 129 and the second concave portion 130, respectively. The first and

second cams

117, 119 and the first and

second recesses

128, 130 are arranged to provide positioning points for the relative rotation of the first and

second connectors

110, 120. It should be noted that the total number of the first bumps 117 and the second bumps 119 may not be equal to the total number of the first recesses 128 and the second recesses 130. For example, the total number of the first recesses 128 and the second recesses 130 may be greater than the total number of the first protrusions 117 and the second protrusions 119, so that the first recesses 128 and the second recesses 130 may provide sufficient positioning points for the first protrusions 117 and the second protrusions 119 when the second connector 120 rotates relative to the first connector 110.

Similarly, when the second connector 120 is connected to the first connector 110, the first wire 160, the first electrical conductor 112, the first conductive layer 123, and the third wire 180 form a first conductive path, and the second wire 170, the second electrical conductor 113, the second conductive layer 124, and the fourth wire 190 form a second conductive path. The first and second conductive paths are equipotentially connected to two power supply terminals of the display, respectively.

In the above embodiments shown in fig. 1 to 4, the same or similar reference numerals denote the same or similar elements, and those skilled in the art will appreciate that these same or similar elements may be substituted or combined with each other in different embodiments without specific description.

Fig. 5 is a schematic cross-sectional view illustrating a connection structure 500 according to a third embodiment of the invention. The connection structure 500 includes a core connector 510 and a shell connector 520. The core connector 510 includes a connector 511, a rounded insulating core body 512, a plurality of conductive bumps 513, and a plurality of first wires 514. A rounded insulating core body 512 is disposed at one end of the connector 511. Each conductive bump 513 protrudes from the rounded insulating core body 512. The first conductive trace 514 is connected substantially equipotentially to the conductive bump 513 from the connector 511 through the rounded insulating core body 512. In detail, each of the first conductive lines 514 is connected to only one corresponding conductive bump 513. In some embodiments, the connector 511 and the rounded insulating core body 512 may comprise various polymeric materials, such as polyurethane, acrylate, methacrylate, epoxy, polycarbonate, polyethylene, or polystyrene, or other suitable insulating polymeric materials. In some embodiments, the conductive bump 513 can be made of a metal or alloy or a suitable material that can form a conductive function. In some embodiments, the first conductive line 514 and the second conductive line 523 can be made of copper metal or other metal material with low resistance.

The shell connector 520 includes an insulative housing 521, a plurality of female conductors 522, and a plurality of second conductors 523. The insulating shell 521 is configured to cover at least a portion of the rounded insulating core body 512 and has an inner curved surface 524 and a plurality of recesses 525 formed on the inner curved surface 524. A recessed conductive element 522 is located within the recessed portion 525, and the recessed conductive element 522 has a recessed surface 526 configured to engage the conductive bump 513. The second conductive line 523 is configured to be substantially equipotential connected to the recessed conductive member 522. In detail, each of the second conductive lines 523 is electrically connected to only one corresponding concave conductive member 522. In some embodiments, the insulating housing 521 may comprise various polymer materials, such as polyurethane, acrylate, methacrylate, epoxy, polycarbonate, polyethylene, or polystyrene, or other suitable insulating polymer materials. In a preferred embodiment, the insulating shell 521 or the rounded insulating core body 512 is made of an insulating material such as epoxy, such that the rounded insulating core body 512 or the insulating shell 521 can allow the core connector 510 to be engaged with the shell connector 520 under pressure deformation. In some embodiments, the concave conductive member 522 may be made of a metal or an alloy or a suitable material capable of forming a conductive function. In some embodiments, the outermost periphery of the shell connector 520 may be coated with an insulating protective layer with a suitable thickness to protect the second conductive wires 523 and prevent the second conductive wires 523 from short-circuiting.

Each conductive bump 513 forms a conductive path with a corresponding first conductive line 514, a corresponding female conductive member 522, and a corresponding second conductive line 523 when shell connector 520 is connected to core connector 510. In other words, the connection structure 500 may provide more than two conductive paths. In an embodiment, when the connection structure 500 replaces the connection structure 100a shown in fig. 3, each of the first conductive lines 514 may be electrically connected to a corresponding gate line or data line of the display 140L, and each of the second conductive lines 523 may be electrically connected to a corresponding gate line or data line of the display 140R. Accordingly, the gate signal or the data signal of the display 140R may be transmitted to the display 140L through the connection structure 500. It should be noted that the total number of the concave conductive members 522 may not be equal to the total number of the conductive bumps 513. For example, the total number of the female conductive elements 522 may be greater than the total number of the conductive bumps 513, such that the female conductive elements 522 may provide sufficient electrical connection points and anchor points for the conductive bumps 513 when the shell connector 520 is rotated relative to the core connector 510.

rounded recesses

614, 615, respectively, such that the first and second

conductive elements

612, 613 have substantially the same or similar profiles as the first and second

rounded recesses

614, 615, respectively. In other embodiments, the first and second

conductive members

612, 613 may be, for example, metal rings, disposed in the first and second

rounded recesses

614, 615, respectively. In addition, the first connector 610 also includes a first conductive line 630 and a second conductive line 640 electrically connecting the first conductive member 612 and the second conductive member 613, respectively. In some embodiments, the first conductive line 630 and the second conductive line 640 may be made of copper metal or other metal materials with low resistance.

The second connector 620 includes a first insulating support 621, a first electrical conductor 622, a second insulating support 623, and a second electrical conductor 624. The first conductor 622 is disposed on the first insulating support 621 and has a first rounded convex surface 625. The second insulating support 623 is disposed opposite to the first insulating support 621. The second conductor 624 is disposed on the second insulating support 623 and has a second rounded convex surface 626. First and second rounded

supports

621 and 623, respectively. When the first and second

electric conductors

622 and 624 are pressed by an external force, the first and second

electric conductors

622 and 624 may be buried in the first and second insulating

supports

621 and 623, respectively. However, when the external force is removed, the first conductor 622 and the second conductor 624 return to their original positions due to the elastic force of the spring. In another embodiment, the first insulating supporting member 621 and the second insulating supporting member 623 may also be elastic supporting members, so as to achieve the above-mentioned effects. The second connector 620 also includes a third conductive line 650 and a fourth conductive line 660 electrically connecting the first conductive body 622 and the second conductive body 624, respectively. In some embodiments, the third conductive line 180 and the fourth conductive line 180 may be made of copper metal or other metal material with low resistance.

Referring to fig. 7, when the second connector 620 is connected to the first connector 610, the first conductor 622 and the second conductor 624 are first pressed by the first connector 610 and are embedded in the first insulating support 621 and the second insulating support 623, respectively. However, when the first and

second conductors

622, 624 move to the positions of the first and second

rounded recesses

614, 615, respectively, the first and

second conductors

622, 624 return to their original positions and contact the first and

second conductors

612, 613, respectively. Further, when the second connector 620 is connected to the first connector 610, the first wire 630, the first conductor 612, the first conductor 622, and the third wire 650 form a first conductive path, and the second wire 640, the second conductor 613, the second conductor 624, and the fourth wire 660 form a second conductive path. When the power rectifying plate R of the display 140 is electrically connected to the external power supply P, two poles of the power supply P can be respectively connected to the first conductive path and the second conductive path through the power rectifying plate R. Accordingly, the power transmitted to the display 140R is transmitted to the display 140L via the connection structure 100. In detail, one pole of the power supply P can be connected to the power rectifying board R through the conductive wire 211, and the power rectifying board R is further connected to the third conductive wire 650 of the second connector 620 through the conductive wire 221. Similarly, the other pole of the power supply P can be connected to the power rectifying board R through the conducting wire 212, and then connected to the fourth conducting wire 660 of the second connector 620 through the conducting wire 222.

It is noted that the connection structure 600 disclosed herein provides not only electrical connections, but also mechanical connections. Because the first rounded recess 614 mates with the first rounded convex surface 625 of the first electrical conductor 622 and the second rounded recess 615 mates with the second rounded convex surface 626 of the second electrical conductor 624, the second connector 620 and the first connector 610 are rotatable relative to one another. That is, the second connector 620 is rotatably connected to the first connector 610. For example, the first rounded convex surface 625 and the second rounded convex surface 626 may be convex hemispheres, and the first rounded recess 614 and the second rounded recess 615 may be concave hemispheres, such that the second connector 620 and the first connector 610 may rotate relative to each other. In other words, the display 140R and the display 140L can rotate relatively due to the connection of the connection structure 600.

Referring to fig. 8, a cross-sectional view of a connection structure 600a according to a fifth embodiment of the invention is shown, wherein the connection structure 600a includes a first connector 610 and a second connector 620. The first connector 610 includes an insulating support 611, a first conductive member 612, and a second conductive member 613. The insulating support 611 has a first rounded recess 614 and a second rounded recess 615 at opposite sides of the insulating support 611, respectively. First and second

conductive elements

612, 613 are located in first and second

rounded recesses

614, 615, respectively. The first connector 610 of the fifth embodiment is different from the fourth embodiment in the pattern of the first rounded recess 614 and the second rounded recess 615. Specifically, the first rounded recess 614 of the first connector 610 of the fifth embodiment has a plurality of first recesses 701, and each first recess 701 is recessed toward the insulating support 611. Furthermore, the second rounded recess 615 has a plurality of second recesses 702, and each second recess 130 is recessed toward the insulating support 611. Other technical features and examples of the second connector 620 of the fifth embodiment may be the same as any of the embodiments or examples of the first connector described above with respect to the fourth embodiment.

The second connector 620 of the fifth embodiment comprises a first insulating support 621, a first conductor 622, a second insulating support 623 and a second conductor 624. The first conductor 622 is disposed on the first insulating support 621 and has a first rounded convex surface 625. The second insulating support 623 is disposed opposite to the first insulating support 621. The second conductor 624 is disposed on the second insulating support 623 and has a second rounded convex surface 626. First and second rounded

convex surfaces

625 and 626 are configured to engage first and second

rounded recesses

614 and 615, respectively, and to contact first and

second conductors

612 and 613, respectively. The second connector 620 of the fifth embodiment differs from the fourth embodiment in the type of the first conductors 622 and the second conductors 624. Specifically, the first conductor 622 of the second connector 620 of the fifth embodiment includes a plurality of first cambered protrusions 703 protruding from a first rounded convex surface 625. In addition, the second electrical conductor 624 includes a plurality of second cambered protrusions 704 protruding from a second rounded convex surface 626. Other technical features and examples of the second connector 620 of the fifth embodiment may be the same as any of the embodiments or examples of the second connector described above with respect to the fourth embodiment.

In light of the above, the first rounded convex 625 and the first cambered surface bump 703 of the connecting structure 600a in the fifth embodiment are configured to match the first rounded concave 614 and the first concave 701, respectively. Again, the second rounded convex surface 626 and the second arc-shaped protrusion 704 are configured to match the second rounded recess 615 and the second recess 702, respectively. The first and

second protrusions

703, 704 and the first and

second recesses

701, 702 are configured to provide positioning points for the first connector 610 and the second connector 620 to rotate relative to each other. It should be noted that the total number of the first bumps 703 and the second bumps 704 may not be equal to the total number of the first recesses 701 and the second recesses 702. For example, the total number of first recesses 701 and second recesses 702 may be greater than the total number of first bumps 703 and second bumps 704, so that the first recesses 701 and the second recesses 702 may provide sufficient positioning points for the first bumps 703 and the second bumps 704 when the second connector 620 rotates relative to the first connector 610.

When the second connector 620 is connected to the first connector 610, the first wire 630, the first conductor 612, the first electrical conductor 622, and the third wire 650 form a first conductive path, and the second wire 640, the second conductor 613, the second electrical conductor 624, and the fourth wire 660 form a second conductive path. The first and second conductive paths are equipotentially connected to two power supply terminals of the display, respectively.

In the above embodiments shown in fig. 6 to 8, the same or similar reference numerals denote the same or similar elements, and those skilled in the art will appreciate that these same or similar elements may be substituted or combined with each other in different embodiments without specific description.
