DESCRIPTION OF EMBODIMENTS
FIG. 1A is a schematic view of a connector according to an exemplary embodiment of the disclosure. FIG. 1B is a schematic view of an electronic device in which the connector of FIG. 1A is employed. FIG. 2A is an exploded view of the shaft depicted in FIG. 1A. Referring to FIG. 1 A through FIG. 2A, in the embodiment, the connector 100 is used for electrically connecting to a plurality of substrates 10 and includes a plurality of bases 110 and a shaft 120. The bases 110 are individually disposed on the substrates 10, and include a plurality of terminals 112 which are embedded in the bases 110. Each terminal 112 has a fixing end 111 electrically connected to the corresponding substrate 10 and a contact end 113 corresponding to the fixing end 111. The shaft 120 is pivoted to the bases 110 and includes a first element 122, a second element 124 and a plurality of conductive rings 126. The first element 122 and the second element 124 are stacked to each other, wherein the two ends of the second element 124 includes a plurality of first conductive circuits 123 and a plurality of second conductive circuits 125. The first conductive circuits 123 are electrically connected to the second conductive circuits 125 correspondingly. Each of the first conductive circuits 123 and each of the second conductive circuits 125 individually have a first pad 124a and a second pad 124b on a surface of the second element 124. The conductive rings 126 are disposed around the two ends of the shaft 120 and electrically connected to the corresponding first pads 124a and the corresponding second pads 124b individually. When the shaft 120 is rotatably assembled to the bases 110, the first pads 124a and the second pads 124b are electrically connected to the terminals 112 via the conductive rings 126, and the conductive rings 126 are capable to continuously contact with the contact ends 113 during the shaft 120 being rotated relative to the bases 110.
In the embodiment, the connector 100 can be a transmission circuit located between the bodies which are pivoted to each other in an electronic device 1. For example, the electronic device 1 can be a note book computer and includes a screen 1a, a linkage 1b and a host 1c. The connector 100 can be applied between the screen 1a and the linkage 1b or between the linkage 1b and the host 1c. The bases 110 are individually disposed on the substrates 10 of the different bodies, and the shaft 120 is pivoted to the bases 110. The first conductive circuits 123 and the second conductive circuits 125 of the two ends of the shaft 120 are conducted with each other, and each conductive circuit 123, 125 can be conducted with the conductive rings 126 via the pads 124a, 124b and contact with the terminals 112 of the corresponding base 110 via the conductive rings 126. In the embodiment, when the shaft 120 is rotated relative to the bases 110, the conductive rings 126 can continuously contact with the terminals 112 and conduct with the corresponding conductive circuits 123, 125. Therefore, if the electronic device 1 uses the connector 100 for connecting to the transmission circuit between the screen 1a and the linkage 1b or between the linkage 1b and the host 1c, the screen 1a of the electronic device 1 can continuously rotate in the same rotating direction and no need to rotate in a reverse direction to be repositioned, and thus it enhances the convenience for users in operation.
FIG. 2B is a schematic view illustrating the second element depicted in FIG. 2A from another view angle. FIG. 2C is a schematic partially enlarged view of FIG. 2B. Referring to FIG. 2A through FIG. 2C, in the embodiment, the first conductive circuits 123 are electrically connected to the second conductive circuits 125 correspondingly. Each of the first conductive circuits 123 and each of the second conductive circuits 125 individually have a first pad 124a and a second pad 124b on a surface of the second element 125. In more detailed, as shown in FIG. 2B, the second element 124 further includes a plurality of connecting circuits 121. The first conductive circuits 123, the second conductive circuits 125 and the connecting circuits 121 are disposed on an inner surface 124c of the second element 124 which faces the first element 122. The connecting circuits 121 correspondingly connect the first conductive circuits 123 and the second conductive circuits 125, so that the first conductive circuits 123 are electrically connected to the second conductive circuits 125 correspondingly.
In other words, as shown in FIG. 2B, the quantity of the circuits 121 and that of the first conductive circuits 123 and the second conductive circuits 125 are the same, and each of the connecting circuits 121 corresponds to a single first conductive circuit 123 and second conductive circuit 125. On the external surface of the second element 124, each of the first conductive circuits 123 and each of the second conductive circuits 125 individually have a first pad 124a and a second pad 124b so as to contact with the conductive rings 126. In the embodiment, the two ends of the second element 124 has a plurality of grooves 124d, wherein the first pads 124a and the second pads 124b are located in the grooves 124d and the conductive rings 126 are assembled to the grooves 124d. Referring to FIG. 2C, the first pads 124a and the second pads 124b are located in the grooves 124d and fill up to the bottom and the side surface of the grooves 124d. In other words, the contact areas between the first pads 124a and the conductive rings 126, and between the second pads 124b and the conductive rings 126, are large, and thus the poor contact between the pads 124a, 124b and the conductive rings 126 and causing the contact resistance being too high can be avoided. In addition, the first element 122 also has a plurality of grooves 122b which are aligned with the grooves 124d of the second element 124.
In the embodiment, the first conductive circuits 123, the second conductive circuits 125 and the connecting circuits 121 can be manufactured by the same process. For example, a laser direct structuring (LDS) process can be used for fabricating the first conductive circuits 123, the second conductive circuits 125 and the connecting circuits 121. In detailed, after the circuit locations for the first conductive circuits 123, the second conductive circuits 125 and the connecting circuits 121 are manufactured by using laser, then by using electroplating process metal materials can be fixed to the circuit locations on the second element 124 to form the circuits. However, the method of fabricating the circuit of the invention is not limited to the above.
In the embodiment, the quantity of the bases 110 of the connector 100 is two and the bases 110 include a first base 110a and a second base 110b, and the substrates 10 correspondingly include a first substrate 10a and a second substrate 10b. Similarly, the terminals 112 include the first terminals 112a disposed on the first base 110a and the second terminals 112b disposed on the second base 110b. The first base 110a is disposed on the first substrate 10a, and the second base 110b is disposed on the second substrate 10b. The first conductive circuits 123 correspond to the first terminals 112a disposed on the first base 110a and the second conductive circuits 125 correspond to the second terminals 112b disposed on the second base 110b. In other words, in the embodiment, the first base 110a is disposed at the screen 1a of the electronic device 1, and the second base 110b is disposed at the linkage 1b of the electronic device 1. The shaft 120 is pivoted to the first base 110a and the second base 110b and connects the screen 1a and the linkage 1b, or connects the linkage 1b and the host 1c, via the first and second conductive circuits 123, 125 located at the two ends of the second element 124. However, the present invention is not intended to limit the shaft 120 to be pivoted to the first base 110a and the second base 110b. In other embodiments not shown in the figures of the disclosure, the shaft can be disposed to three or more bases as required, and regarding the shaft, third conductive circuits or other conductive circuits can also be increased to the shaft according to the quantity of the bases, so that the connector can be applied to different electronic devices.
As shown in FIG. 2A, the first base 110a and the second base 110b individually have a first opening 110c and a second opening 110d. The terminals 112 of the first base 110a and the second base 110b are disposed on at least one side of the first opening 110c and the second opening 110d. In other words, through the first opening 110c and the second opening 110d disposed on the first base 110a and the second base 110b, the height in which the terminals 112 are embedded in the bases 110 can be reduced. When the shaft 120 is assembled to the bases 110, the shaft 120 can be closer to the substrates 10, so as to reduce the height of the connector 100. In addition, in the embodiment, the first terminals 112a of the first base 110a are disposed on two opposite sides of the first opening 110c, and the second terminals 112b of the second base 110b are disposed on two opposite sides of the second opening 110d. The first terminals 112a and the second terminals 112b located at the two sides of the first opening 110c and the second opening 110d are alternately arranged, so as to reduce the length of each opening.
In FIG. 2A, the shaft 120 further includes a supporting member 128, and the supporting member 128 is disposed between the first element 122 and the second element 124. The supporting member 128 is used for relatively pushing outward the first element 122 and the second element 124, so that the conductive rings 126 can be firmly locked in the grooves 124d of the second element 124 and firmly propped against the first pads 124a and the second pads 124b. The material of the supporting member 128 is plastic, for example. However, the present invention is not limited thereto. A buckling method can be used in fixing the supporting member 128 to the first element 122 and the second element 124. For example, an end of the supporting member 128 has a first support positioning portion 128a and a second support positioning portion 128b, wherein an end of the first element 122 correspondingly has a first positioning portion 122a, and an end of the second element 124 correspondingly has a second positioning portion 124e. When the first element 122, the supporting member 128 and the second element 124 construct the shaft 120, the first support positioning portion 128a and the first positioning portion 122a are positioned to each other, and the second support positioning portion 128b and the second positioning portion 124e are positioned to each other. In detailed, as shown in FIG. 2A and FIG. 2B, the first positioning portion 122a and the second positioning portion 124e are recesses, and the first support positioning portion 128a and the second support positioning portion 128b are protrusions. Taking the first support positioning portion 128a as an example, the first support positioning portion 128a includes an elastic arm 128d and a ball portion 128c. When the supporting member 128 is assembled between the first element 122 and the second element 124, the ball portion 128c interferes with the inner surface of the recess, so that the elastic arm 128d deforms and the ball portion 128c is assembled to the recess of the first positioning portion 122a. Similarly, the second support positioning portion 128b can also be assembled to the second positioning portion 124e, and it is not repeated herein.
Moreover, the connector 100 of the embodiment further includes a plurality of fixing members 130, and the material of the fixing members 130 is nylon, however the present invention is not limited thereto. The fixing members 130 are disposed at the two ends of the bases 110 (in the present embodiment, the first base 110a and the second base 110b). Each of the fixing members 130 has a hole 132 and a buckling portion 134. Each fixing member 130 is fixed to each of the bases 110 through the buckling portion 134. The shaft 120 is assembled to the hole 132 of each fixing member 130 so as to rotate relative to the bases 110. In other words, at each of the two sides of the first base 110a and the second base 110b, the fixing members 130 are disposed thereto, and the bottom of each fixing member 130 has a buckling portion 134, wherein the buckling portion 134 is a locking hook, for example. Since the first base 110a and the second base 110b are arranged side by side, the fixing members 130 can be arranged along the same direction, so that the shaft 120 can be pivoted in the holes 132 of the fixing members 130. In addition, in the embodiment, a lubrication layer (not shown) is further disposed between the shaft 120 and the hole 132 of the fixing member 130, so as to reduce the friction force between the shaft 120 and the bases 110 when relatively rotated.
FIG. 3A to FIG. 3E are schematic views illustrating the process steps of the assembling of the connector depicted in FIG. 1A. Referring to FIG. 3A through FIG. 3E, in the assembling process shown in FIG. 3A through FIG. 3E, the assembling method of the connector 100 are described in FIG. 3A, first the first base 110a and the second base 110b are individually disposed on the first substrate 10a and the second substrate 10b. For example, by using a reflow process, the fixing ends 111 of the first terminals 112a and the second terminals 112b can be fixed to the first substrate 10a and the second substrate 10b. As shown in FIG. 3B, the first element 122 and the second element 124 are stacked to each other, wherein all of the first conductive circuits 123, the second conductive circuits 125 and the connecting circuits 121 of the second element 124 are covered by the first element 122.
Then, as shown in FIG. 3C, the conductive rings 126 are disposed around the recesses 124d of the element 124 and conducted to the corresponding first pads 124a and the corresponding second pads 124b individually. After the conductive rings 126 are disposed around the recesses 124d of second element 124, as shown in FIG. 3D, the supporting member 128 is assembled between the first element 122 and the second element 124, so that the first element 122 and the second element 124 are pushed outward to fix the conductive rings 126 and complete the shaft 120 assembling. Finally, as shown in FIG. 3E, the fixing members 130 are assembled to the constructed shaft 120 and then it is assembled to the first base 110a and the second base 110b of the first substrate 10a and the second substrate 10b, so as to complete the assembling process of the connector 100.
In light of the foregoing, in the connector of the disclosure, the shaft is pivoted to a plurality of bases and the bases are individually disposed on different substrates. The conductive circuits of the two ends of the second element are conducted with each other, and every end of the conductive circuits are conducted with the conductive rings via the pads to contact with the terminals of the corresponding base via the conductive rings. When the shaft is rotated relative to the bases, the conductive rings continuously contact with the terminals so that the terminals and the corresponding conductive circuits are conducted. Furthermore, the inner portion of the second element further includes connecting circuits for connecting the conductive circuits located at the two ends of the second element. The first pads and the second pads are disposed on the bottom of the grooves located on the external surface of the element, and the conductive rings are assembled to the grooves to ensure to have a good contact. Therefore, when the connector of the disclosure is applied to the transmission lines connected between different bodies of an electronic device, the connector can maintain the conductivity of the transmission lines during the rotating of the bodies, and the bodies are no need to be rotated in a reverse direction to be repositioned.
Although the present invention has been described with reference to the above embodiments, it will be apparent to one of ordinary skill in the art that modifications to the described embodiments may be made without departing from the spirit of the invention.
