1. Field of the Invention
The present invention relates to a guideway device, and particularly to a guideway device for server casings.
2. Description of Related Art
Generally, server casings include the server casing of the MTCA (micro telecom computing architecture) specification and the server casing of the ATCA (advanced telecom computing architecture) specification. The server casing of the MTCA specification has the height corresponding to that of electronic cards, so a plurality of guideway devices lies flat on upper inner side walls and lower inner side walls of the server casing of the MTCA specification to be locked thereon and users can respectively connect electronic cards slidably between guideway devices opposite to each other up and down so that each electronic card is inserted in a corresponding electrical connector in the server casings of the MTCA specification.
For the server casing of the ATCA specification, since the server casing of the ATCA specification are much higher than electronic cards, electronic cards are connected with electrical connectors disposed in the server casing of the ATCA specification by an adapter interface for electronic cards. The adapter interface for electronic cards includes an upper board, a circuit substrate and a plurality of guideway devices of another kind of specification which is locked between the upper board and the circuit substrate. A plurality of electronic card connectors and an adapter connector are disposed on one side face of the circuit substrate, facing the upper board. Each electronic card is slidably connected between adjacent guideway devices and inserted in a corresponding electronic card connector. After users turn the adapter interface for electronic cards 90 degrees, the height of the adapter interface just corresponds to that of the server casing of the ATCA specification. And then, the adapter interface for electronic cards is inserted into the server casing of the ATCA specification and the adapter connector located on the adapter interface for electronic cards is electrically connected with an electrical connector disposed in the server casing of the ATCA specification.
The above mentioned guideway devices for server casings of the two kinds of specifications all have combining holes and guiding grooves for being passed through by screws. For the guideway devices fixed in the server casing of the MTCA specification, their combing holes and guiding grooves are located in the same side face; for the guideway devices fixed in the adapter interfaces for electronic cards, their combing holes and guiding grooves are located in different side faces. Since the guideway devices for server casings of the two kinds of specifications have different structures, manufacturers must develop two sets of molds, which brings cost burden.
Hence, the inventors of the present invention believe that the shortcomings described above are able to be improved and finally suggest the present invention which is of a reasonable design and is an effective improvement based on deep research and thought.
A main object of the present invention is to provide a guideway device for server casings which can reduce manufacture costs greatly.
To achieve the above-mentioned object, a guideway device for server casings in accordance with the present invention is provided. The guideway device for server casings includes: a fixing board which includes a first casing connecting end face, a second casing connecting end face, a third casing connecting end face and a fourth casing connecting end face, the first casing connecting end face and the second casing connecting end face located on two opposite sides of the fixing board and the third casing connecting end face and the fourth casing connecting end face located on the other two opposite sides of the fixing board, wherein the first casing connecting end face and the second casing connecting end face respectively have at least one first combining hole and at least one second combining hole, the fixing board further has a plurality of through-holes extending therethrough each of which has two ends respectively located on the third casing connecting end face and the fourth casing connecting end face; and a pair of guiding grooves concavely formed in the third casing connecting end face and the fourth casing connecting end face.
The efficacy of the present invention is as follows: the guideway device for server casings of the present invention can be adapted for the server casing of the ATCA (advanced telecom computing architecture) specification and the server casing of the MTCA (micro telecom computing architecture) specification, thereby manufacturers needn't manufacture two kinds of guideway devices for server casings of the two kinds of specifications, respectively. Accordingly, manufacture costs can be reduced greatly and market competition capability is intensified.

Further, the first casing connecting end face 11, the second casing connecting end face 12, the third casing connecting end face 13 and the fourth casing connecting end face 14 respectively have a plurality of first positioning poles 113, a second positioning pole 122, a plurality of third positioning poles 131 and a plurality of fourth positioning poles 141 protruding therefrom. There is one concave portion 111 between each two positioning poles 113. Some third positioning poles 131 and fourth positioning poles 141 are adjacent to the through-holes 15, other third positioning poles 131 and fourth positioning poles 141 are adjacent to the guiding grooves 2.

The guideway device 10 further includes an integral metal elastic piece 3. The metal elastic piece 3 includes a first fixed portion 31, two second fixed portions 32, a pair of fixed reverse hooks 33, a contacting portion 34 and a bent portion 35. The two second fixed portions 32 are connected to two opposite sides of the first fixed portion 31. The pair of fixed reverse hooks 33 is connected with the ends of the pair of second fixed portions 32, which are far away from the first fixed portion 31. The contacting portion 34 is slantways connected to one side of the second fixed portions 32. The bent portion 35 is connected with the end of the contacting portion 34, which is far away from the second fixed portions 32.

The circuit substrate 42 has a plurality of spaced guideway fixing holes 423, and the second combing holes 121 formed in the bottoms of the guiding devices 10 are located corresponding to the guideway fixing holes 423 of the circuit substrate 42. Screws pass through the guideway fixing holes 423 of the circuit substrate 42 from bottom to top and are connected with the second combining holes 121 of the guideway devices 10, so that the bottoms of the guideway devices 10 are fixed on the circuit substrate 42.
The upper fixing frame 41 has a plurality of spaced guideway fixing holes 411, corresponding to the first combining holes 112 of the guideway devices 10. In the same way, the tops of the guideway devices 10 are fixed on the upper fixing frame 41 via screws.

The third casing connecting end faces 13 and the fourth casing connecting end faces 14 abut against the upper fixing board 61 and the lower fixing board 62. The positions of the through-holes 15 align with the positions of the upper fixing holes 611 and the lower fixing holes 621. The third positioning poles 131 and the fourth positioning poles 141 are inserted into the upper positioning holes 612 and the lower positioning holes 622. Furthermore, a plurality of screws pass through the through-holes 15, the upper fixing holes 611 and the lower fixing holes 612. The thread pitch of the screws is similar to the thickness of the upper fixing board 61 and the thickness of the lower fixing board 62. Accordingly, based on the screws, the guideway devices 10 are fixed on the upper fixing board 61 and the lower fixing board 62.
