With the rapid development of science and technology, the portable electronic device such as tablet PC or notebook computer (NB) has been widely used due to the advantage of portable carrying and operation simplicity. Most of the notebook computers are equipped with network connectors for connecting, for example, RJ45-type plug of network cable.
A network connector of a notebook computer is mostly disposed at a side edge of the host. To meet the developing trend of lightness and slimness, many notebook computers adopt the design of half-sectional network connectors. In the design of a half-sectional network connector, a bottom casing of a notebook computer has a notch. A part of the network connector corresponds to the notch, and a cover disposed on the bottom casing covers the notch. When the cover is expanded to expose the notch, a plug of a network cable may be plugged into the network connector. In general, the cover needs to be restored automatically by elasticity of an elastic component after being expanded. In the conventional design, the elastic component is usually fixed by the components fused to the bottom casing.

DESCRIPTION OF EMBODIMENTS
FIG. 1 is a partial perspective view of an electronic device according to one embodiment of the invention. Referring to FIG. 1, the electronic device 100 of the present embodiment is, for example, a host of a notebook computer. The electronic device 100 includes a casing 110 and a connector module 120. The casing 110 is, for example, a bottom casing of the notebook computer, having a notch 112. The connector module 120 includes a connector main body 122 and a cover 124. The connector main body 122 is, for example, a network connector. The connector main body 122 is disposed on the casing 110 and corresponds to the notch 112 of the casing 110. The cover 124 is pivoted with the casing 110, and able to cover or expose the notch 112, which will be described in detail as below.
FIG. 2 is a schematic view of the cover exposing the notch in FIG. 1. The cover 124 is adapted to rotate to a first position P1 shown in FIG. 1 to cover the notch 112, or rotate to a second position P2 shown in FIG. 2 to expose the notch 112. The connector main body 122 has an open end 122a. The open end 122a corresponds to the notch 112. When the cover 124 is located at the second position P2 to expose the notch 112, the open end 122a of the connector main body 122 and the notch 112 of the casing 110 form a socket, and an external connector 50, for example, a plug of a network cable, is adapted to be plugged into the connector main body 122 through the socket.
FIG. 3 is a perspective view of a part of the components of the electronic device in FIG. 1. FIG. 4 is a perspective view of a part of the components of the electronic device in FIG. 3. FIG. 5 is an exploded view of the electronic device in FIG. 3. The connector main body 122 in FIG. 1 and FIG. 2 are not shown in FIG. 3 to FIG. 5 for better and clearer illustration. Referring to FIG. 3 to FIG. 5, the connector module 120 of the present embodiment further includes a first position-limiting portion 126, a second position-limiting portion 127 and an elastic component 128. The first position-limiting portion 126 and the second position-limiting portion 127 are integrally formed with and connected to the casing 110. The first position-limiting portion 126 has at least one position-limiting hole 126a (two are illustrated). A gap G is formed between the first position-limiting portion 126 and the second position-limiting portion 127. The elastic component 128 is disposed at the gap G between the first position-limiting portion 126 and the second position-limiting portion 127 and partially inserted into the position-limiting hole 126a, and the cover 124 presses the elastic component 128 onto the casing 110. A user may use the external connector 50 to resist the elastic force of the elastic component 128, so as to push the cover 124 from the first position P1 shown in FIG. 1 to the second position P2 shown in FIG. 2, such that the external connector 50 can be plugged into the connector main body 122 successfully. When the external connector 50 is removed, the cover 124 is restored from the second position P2 to the first position P1 by the elastic force of the elastic component 128.
To be more specific, in the present embodiment, the elastic component 128 is, for example, a torsion spring and includes at least one spring body 128a (two are illustrated), at least one first spring arm 128b (two are illustrated) and a second spring arm 128c. The elastic component 128 is connected between the first spring arms 128b and the second spring arm 128c, and located at the gap G between the first position-limiting portion 126 and the second position-limiting portion 127. The first spring arm 128b is inserted into the position-limiting hole 126a, and the cover 124 leans against the second spring arm 128c. With the disposition, the first position-limiting portion 126 and the second position-limiting portion 127 restrain the moving range of the elastic component 128 along a first direction Y (illustrated in FIG. 3). The position-limiting hole 126a restrains the moving ranges of the elastic component 128 along a second direction X (illustrated in FIG. 3) and a third direction Z (illustrated in FIG. 3). The cover 124 presses the elastic component 128 onto the casing 110 along the third direction Z. Herein, the first direction Y is perpendicular to the second direction X, and the third direction Z is perpendicular to the first direction Y and the second direction Z. Thereby, the elastic component 128 is disposed on the casing 110 by the structural interference of the first position-limiting portion 126, the second position-limiting portion 127 and the cover 124. Thus, no fusion process is needed to perform the assembly thereof, such that the connector module 120 is easy to be assembled and disassembled.
Referring to FIG. 3 to FIG. 5, in the present embodiment, the connector module 120 further includes a first pivoting portion 121 and a second pivoting portion 123. The first pivoting portion 121 and the second pivoting portion 126 are integrally formed with and connected to the casing 110 and have a first pivoting hole 121a and a second pivoting hole 123a respectively. A back end 124a of the cover 124 has a first axial portion 124b and a second axial portion 124c opposite to each other. The back end 124a of the cover 124 is located between the first pivoting portion 121 and the second pivoting portion 123, and the first axial portion 124b and the second axial portion 124c are pivoted with the first pivoting hole 121a and the second pivoting hole 123a respectively, such that the cover 124 can rotate about the first axial portion 124b and the second axial portion 124c. The first pivoting portion 121 of the present embodiment has a slot 121b. The slot 121b is connected to the first pivoting hole 121a. The first pivoting hole 121a opens at a side edge of the first pivoting portion 121 through the slot 121b, such that the first pivoting portion 121 is in an open-circle formation for the first axial portion 124b to pass through the slot 121b to be moved into the first pivoting hole 121a. In addition, the second pivoting portion 126 does not have a slot and is in a close-circle formation, so as to avoid the second axial portion 124c being separated from the second pivoting portion 123.
Referring to FIG. 1 and FIG. 2, the cover 124 is adapted to rotate from the first position P1 to the second position P2 along a first rotating direction R1, and is adapted to rotate from the second position P2 to the first position P1 along a second rotating direction R2. FIG. 6 is a partial view of the electronic device in FIG. 2. Referring to FIG. 3 and FIG. 6, the cover 124 of the present embodiment has at least one protrusion 124a (two are illustrated). When the cover 124 is located at the second position P2 as shown in FIG. 2 and FIG. 6, the protrusion 124d and the casing 110 are structurally interfered with each other as shown in FIG. 6 to stop the cover 124 from rotating along the first rotating direction R1. In the present embodiment, the connector module 120 further includes two position-limiting blocks 129, the two position-limiting blocks 129 correspond to the two protrusions 124d of the cover 124 respectively, so as to further ensure the cover 124 not wobbling along the second direction X.
Referring to FIG. 3 to FIG. 5, the connector module 120 of the present embodiment further includes a locking hook 125. The locking hook 125 is integrally formed with and connected to the casing 110. When the cover 124 is located at the first position P1 as shown in FIG. 1 and FIG. 3, the cover 124 and the locking hook 125 are structurally interfered with each other to stop the cover 124 from rotating along the second rotating direction R2. In the present embodiment, the cover 124 has an opening 124e and a pin 124f. The pin 124f is located in the opening 124e. The locking hook 125 is adapted to be inserted into the opening 124e and locked with the pin 124f, so as to be structurally interfered with the cover 124.
The assembly method of the elastic component 128 and the cover 124 of the present embodiment are provided as follows to illustrate in detail respectively with figures. FIG. 7A and FIG. 7B are schematic views of the assembly method of the connector module in FIG. 3. First of all, the first spring arms 128b of the elastic component 128 is inserted into the position-limiting hole 126a of the first position-limiting portion 126 along the direction of the arrow shown in FIG. 7A to change to the state shown in FIG. 4. At the time, the elastic component 128 is fixed to the casing 110 by the first position-limiting portion 126 and the second position-limiting portion 127. Next, the second axial portion 124c of the cover 124 is inserted into the second pivoting hole 123a of the second pivoting portion 123, as shown in FIG. 7B. When the second axial portion 124c is located in the second pivoting hole 123a, the first axial portion 124b passes through the slot 121b of the first pivoting portion 121 to be moved into the first pivoting hole 121a. Then, the cover 124 is pressed from the state shown in FIG. 7B down to the state shown in FIG. 3B by resisting the elastic force of the elastic component. Meanwhile, the cover 124 is locked by the locking hook 125 and presses the elastic component 128 onto the casing 110, so as to finish the assembly of the elastic component 128 and the cover 124.
FIG. 8 is a schematic view of the first pivoting portion and the first axial portion in FIG. 3. FIG. 9 is a schematic view of the first pivoting portion and the first axial portion in FIG. 7B. Referring to FIG. 8 and FIG. 9, the first axial portion 124b of the present embodiment has at least one side S (two are illustrated). An outer diameter D1 of the first axial portion 124b along a direction perpendicular to the side S is smaller than an inner diameter D2 of the slot 121b of the first pivoting portion 121, and an outer diameter of the first axial portion 124b along any directions other than the direction perpendicular to the side S is greater than the inner diameter D2 of the slot 121b. With the design described above, when the side S of the first axial portion 124b, as shown in FIG. 9, is parallel to an extension direction E of the slot 121b, the first axial portion 124b can pass through the slot 121b to be moved into or moved out of the first pivoting hole 121a, such that the cover 124 is easy to be assembled and disassembled. When the first axial portion 124b is located within the first pivoting hole 121a and the cover 124 is pressed from the state shown in FIG. 7B down to the state shown in FIG. 3, the side S, as shown in FIG. 8, is not parallel to the extension direction E of the slot 121b. Meanwhile, the first axial portion 124b can not pass through the slot 121b and is restrained in the first pivoting hole 121a. 
In the present embodiment, after the cover 124 is assembled, the rotating range of the cover 124 is restrained between the first position P1 shown in FIG. 1 and the second position P2 shown in FIG. 2. When the cover 124 is located within the rotating range described above, the side 0 of the first axial portion 124b is not parallel to the extension direction E of the slot 121b because the cover 124 does not rotate to the states shown in FIG. 7B and FIG. 9, so as to ensure the first axial portion 124b restrained in the first pivoting hole 121a and keep the first axial portion 124b from shedding.
The disassembly method of the elastic component 128 and the cover 124 will be described in detail as follow. First of all, a force is applied on the cover shown in FIG. 3, such that the cover 124 is separated from the locking hook 125. Next, the cover 124 is lifted up to the state shown in FIG. 7B, such that the first axial portion 124b rotates to the state shown in FIG. 9. Meanwhile, the side S of the first axial portion 124b is parallel to the extension direction E of the slot 121b, such that the first axial portion 124b can pass through the slot 121b via the smaller outer diameter D1 thereof to be moved out of the first pivoting hole 121a. After the first axial portion 124b is moved out of the first pivoting hole 121a, the second axial portion 124c is moved out of the second pivoting hole 123a, so as to finish the disassembly of the cover 124. When the cover 124 is moved away to expose the elastic component 128 as shown in FIG. 4, the elastic component 128 is no longer pressed by the cover 124, and able to be disassembled from the casing 110. The cover 124 and the elastic component 128 can be easily disassembled since the connector module 120 is not assembled by fusion process, so as to avoid putting a whole bottom casing of a notebook computer to total waste due to defect or damage of the cover 124 and the elastic component.
In sum, in the connector module of the present invention, the spring body of the elastic component is disposed at the gap between the first position-limiting portion and the second position-limiting portion and is partially inserted into the position-limiting hole of the first position-limiting portion by the first spring arm thereof. The cover is disposed by the first pivoting portion, the second pivoting portion and the locking hook on the casing, and leans against the second spring arm of the elastic component to press the elastic component onto the casing. Thereby, the cover is disposed at the casing by the structural interference of the first pivoting portion, the second pivoting portion and the locking hook, and the elastic component is disposed at the casing by the structural interference of the first position-limiting portion, the second position-limiting portion and the cover. Thus, no fusion process is needed to perform the assembly thereof, such that the connector module is easy to be assembled and disassembled.
