DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
FIG. 1 is a schematic view of a guiding structure of a connector according to an embodiment of the present invention, and FIG. 2 is a schematic view of inserting the guiding structure of the connector of FIG. 1 to a case.
Referring to FIG. 1, a guiding structure 100 of the connector includes a holder 110 and an operating element 120. The holder 110 has a board 112, two folded edges 114, and at least one connector accommodating cavity 116 (for example, two). The board 112 is, for example, elongated, such that the board 112 may be accommodated in a guideway 210, and move along guiding slots of the guideway 210. Particularly, in this embodiment, two opposite sides of the guideway 210 have, for example, two guiding slots 212, and a vertical section of the guiding slot is, for example, in a similar shape of C. The board 112 is accommodated between the two guiding slots 212, and move along a linear path.
Next, two folded edges 114 are located on two opposite sides of the board 112, and a vertical section of the folded edge is, for example, in a similar shape of C. Particularly, the two folded edges 114 each have a slanting surface 114s, such that the operating element 120 may be in a slanting state. When the operating element 120 is slanted on the board 112, the operating element 120 has a bending portion 122 and a fixing portion 124 relative to the two folded edges 114. The bending portion 122 is, for example, an elastic blade having a predetermined elastic force, for abutting against the board 112, and the bending portion 122 is pressed in the two folded edges 114 of the board 112 in a normal state, such that the operating element 120 is normally kept on the position as shown in FIG. 1 through the elastic force. In addition, the fixing portion 124 is, for example, a board part located on left and right sides of the bending portion 122, extends from an upper part of the board 112 to a lower part of the board 112, and has a first fastening part P1 extending toward the guideway 210. Under a fastening state (not shown), the first fastening part P1 (for example, a hook) may lock with the a second fastening part P2 (for example, a slot) on a predetermined position of the guideway 210, so as to fix the guiding structure 100 of the connector on the guideway 210, thereby preventing loosing. When the user intends to disassemble the guiding structure of the connector 100, the user only needs to apply a force downwards on the operating element 120 to neutralize the elastic force of the bending portion 122, and the fixing portion 124 will move upwards relative to the board 112, such that the first fastening part P1 is separated from the second fastening part P2. At this time, when the user holds a handle portion 118 on the end of the board 112 to pull backwards, the guiding structure of the connector 100 may be moved out of the guideway 210 through the above operation.
In other not shown embodiments, the operating element 120 is not limited to be disposed on the board 112 in the above manner, and the relative position of the bending portion 122 and the fixing portion 124 of the operating element 120 is not limited to the above manner. At the same time, in an embodiment of the present invention, the hook of the operating element 120 locks with the slot of the guideway 210, and it is not used to limit the present invention. In other embodiments, the operating element 120 may be lock with the guideway 210 by using different fastening structures. In addition, in the not shown embodiments, the operating element 120 is not limited to use the two folded edges 114 as a stopping portion of elastic deformation, and it is also possible to limit the position of the operating element 120 by using other stopping structure, for example, a hole (not shown) is formed on the handle portion 118, so as to place an end portion of the operating element 120 and limit the position of the operating element.
Next, referring to the connector accommodating cavity 116 and connectors 220 and 222 of FIGS. 1 and 2, the connectors 220 and 222 are, for example, a cable connector and a power source connector each having a plurality of signal lines, for respectively connecting signals and power sources among different elements and circuit boards. The cable connector includes, for example, a USB interface connector, an IEEE1394 interface connector, an IDE interface connector, and an SATA interface connector etc. In this embodiment, the connector accommodating cavity 116 is disposed on one end (front end) of the board 112, such that the connectors 220 and 222 are guided to predetermined positions in the case 200 with the board 112, and it is convenient for the user to assemble the connectors 220 and 222. As shown in FIG. 2, when the board 112 enters the case 200 through an inserting hole 202 of the case 200, the front end of the board 112 extends toward connector slots 204 and 206 (for example, fixed on a circuit board 230, and spaced from the inserting hole 202 by a predetermined distance), such that ports of the connectors 220 and 222 are corresponding to the connector slots 204 and 206, so as to be connected to each other, thereby transmitting the signals or the power sources.
FIG. 3 is a schematic view of the connector accommodating cavity of FIG. 1. Particularly, the connector accommodating cavity 116 has at least one accommodating chamber 116c, and the accommodating chamber 116c has, for example, an inlet 116a and an outlet 116b. When the connector 220 enters the accommodating chamber 116c through the inlet 116a, the port of the connector 220 is exposed in the outlet 116b and faces the direction of the connector slot 204. In this embodiment, the connector accommodating cavity has two accommodating chambers 116c and 116d, for respectively accommodating the connectors 220 and 222 with different functions, for example, the cable connector and the power source connector.
Next, referring to FIGS. 1 and 3, in this embodiment, the connector accommodating cavity 116 has, for example, an embedding portion 116e and a buckling portion 116f (for example, hook), respectively located on two opposite sides of the accommodating chamber 116c. Therefore, when the connector 220 enters the accommodating chamber 116c, the buckling portion 116f may fix the connector 220 in the accommodating chamber 116c, such that it is not easy to result in shaking or falling. In addition, FIG. 4 is a schematic bottom view of the board and the connector accommodating cavity of FIG. 1. In FIG. 4, the embedding portion 116e is adapted to penetrate a groove 112s of the board 112 and is exposed on a bottom surface 112b of the board 112, and a hook 116g locks with a slot of the bottom surface 112b, so as to fix the connector accommodating cavity 116 on a top surface 112a of the board 112. Therefore, the connector accommodating cavity 116 and the board 112 may be combined as a whole by simply operating the embedding portion 116e, and during the assembling and the disassembling processes, tools is not required for locking or unlocking, thereby achieving a tool-free operation.
To sum up, the guiding structure of the connector of the present invention has a lengthened board, such that it is convenient to guide the connector to a predetermined position in the case with the board. Therefore, in the narrow space of the case of the server, the serial connection of the main board to another main board (or an adapting board) may be achieved through the guiding structure of the present invention, the connector is made to abut against and electrically connect to the connector slot without any special tools or disassembling the case, such that it is convenient for the operating personnel to insert and extract the connector.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
