Abstract
A computer input/output (I/O) cable plug retaining seat comprises a retaining cover and a base. The seat can be connected to a computer I/O plug, such as a well-known CENTRONICS cable plug. Four screws are used to secure the cable plug between the retaining cover and the base. A pair of fixing screws secure the retaining seat with cable plug to the rear cover of an equipment shelf so that when a channel unit slides from the card guide of the equipment shelf, the channel unit connector will be led into the guide holes by means of guide pins so that the channel unit connector is precisely aligned with the cable plug. When a user wishes to remove the channel unit from the equipment shelf, the channel unit is extracted directly without having to disconnect the cable. Thus, the objective of rapid assembly and disassembly is achieved.

Description
Field of the Invention
[0002] The present invention relates to a computer input/output (I/O) cable plug retaining seat for use in a computer equipment shelf system. When a channel unit of a shelf is to be changed, the channel unit can be pulled out without needing to detach the cable plug.
Background of the Invention
[0003] In the connection of a computer I/O cable such as the well-known parallel CENTRONICS cable, a channel unit connector is pushed along the card guide of an equipment shelf and the connector of the channel unit protrudes from a slot on the rear cover of the equipment shelf so the external cable plug is directly coupled to the connector of the channel unit. Then, the screws adjacent to the cable plug are used to fix the two together so as to avoid separation. However, this prior technology has the following disadvantages:
[0004] 1. When the channel unit is to be pulled out from the shelf, the screw at the backside of the shelf must be released. If it is necessary for the channel unit to be pulled out and inserted frequently, the operation is inconvenient.
[0005] 2. When the connector of the cable is to be separated from the connector of the channel unit, the cable plug is not attached and is placed anywhere. When it is desired to connect the channel unit with the cable plug again, the polarities, positions and order must be identified again. The efficiency of this operation is very poor.
Summary of the Invention
[0006] Accordingly, the primary object of the present invention is to provide a computer I/O cable plug retaining seat, wherein as a channel unit of an equipment shelf is desired to be updated, the channel unit can be pulled out directly, the operation of loosening or locking the screws of the cable plug is unnecessary. The operation is convenient and time is saved.
[0007] Another object of the present invention is to provide a computer I/O cable plug retaining seat wherein, by the guide holes and guide pins, the male and female connectors can be combined precisely.
[0008] To achieve the above objects, the present invention provides a computer I/O cable plug retaining seat comprising:
[0009] a retaining cover having an inverted channel shape and having an opening in a middle section thereof; an upper side thereof having four screw holes for engaging with screws; the retaining cover is used to surround a cable plug and being then locked to a base;
[0010] a base having a channel shape and having a bottom containing a square opening; an upper side thereof having two fixing screws, four spacers, and two positioning holes; the two fixing screws serving to fix the base to the rear cover of an equipment shelf; the four spacers serving for being passed through by screws so as to fix the base and retaining cover; the two guide holes serving to position the cable plug correctly when connecting the retaining cover to the base and for positioning the plug over the guide pins; and
[0011] two guide pins being installed on a channel unit connector; the guide pins being inserted into the guide holes of the base so that the channel unit connector is precisely aligned with the cable plug on the retaining seat.
[0012] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings.
Brief Description of the Drawings
[0013] FIG. 1 is an exploded view of the computer I/O cable plug retaining seat according to the present invention.
[0014] FIG. 2 is a perspective view of the computer I/O cable plug retaining seat of the present invention.
[0015] FIG. 3 is a schematic view of the computer I/O cable plug retaining seat of the present invention.
Detailed Description of the Preferred Embodiments
[0016] Referring to FIG. 1, a computer I/O plug, such as the commonly known CENTRONICS cable plug combined with the retaining seat of the present invention is illustrated. The computer I/O cable plug retaining seat includes the following components:
[0017] A retaining cover 11 has an inverted channel shape and has an opening at a middle section thereof. An upper side thereof has four threaded screw holes 111 for engaging with four screws. Thus, the retaining cover 11 can be placed over the cable end of cable plug 2 and then locked to base 12.
[0018] A base 12 has a channel shape and has a bottom having a square opening. An upper side thereof has two fixing screws 121, four spacers 122, and two guide holes 123. The two fixing screws 121 serve for attaching the base 12 to the rear cover 31 of an equipment shelf. The four spacers 122 are passed through by screws 4 when attaching the base 12 and retaining cover 11. The two guide holes 123 serve to position cable plug 2 correctly when connecting the retaining cover 11 to the base 12 and for positioning the plug over the guide pins 511.
[0019] Two guide pins 511 are installed to a channel unit connector 51. The guide pins 511 are inserted into the guide holes 123 of the base 12 so that the channel unit connector 51 is precisely aligned with the cable plug 2 on the retaining seat.
[0020] Referring to FIG. 2, a perspective view of the computer I/O cable plug retaining seat of the present invention is illustrated. It is appreciated from the drawing that in the retaining seat 1 of the present invention, the cable plug 2 is enclosed and fixed and then is locked to the rear cover 31 of the shelf. The guide pins adjacent to the channel unit connector pass through the guide holes 123 of the base 12 and the screw holes 21 at two sides of the cable plug 2 so that the channel unit connector 51 is precisely aligned with the cable plug 2.
[0021] With reference to FIG. 3, a schematic view for realizing the computer I/O cable plug retaining seat of the present invention is illustrated. A plurality of cable plugs 2 can be fixed to the rear cover 31 of an equipment shelf. When channel unit 5 slides from the card guide 32 of the shelf 3, the channel unit connector 51 will guide into the guide holes 123 by the guide pins 511 so that the channel unit connector 51 may be precisely aligned with the cable plug 2. When the user desires to remove the channel unit 5 from the shelf 3, it is only necessary to extract the channel unit 5 directly.
[0022] The computer I/O cable plug retaining seat of the present invention has the following advantages over the prior technology:
[0023] 1. In the computer I/O cable plug retaining seat of the present invention, when it is desired to update the channel unit of a shelf, the channel unit can be pulled out directly, the operation of loosening or locking the screws of the cable plug is unnecessary. The operation is convenient and time is saved.
[0024] 2. In the computer I/O cable plug retaining seat of the present invention, by the guide holes and guide pins, the male and female connectors can be precisely aligned.
[0025] The present invention thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the technology are intended to be included within the scope of the appended claims.
