BACKGROUND
Field of the Invention
The present invention relates to patch panels.
2. Description of Related Art
Generally speaking, after a printed circuit board (PCB), such as a motherboard, is assembled, it needs to be tested via a patch panel and a tester.
Referring to FIG. 1, a conventional patch panel is shown. The patch panel includes a connector 100 having nine signal input terminals 120, and an output module 200 having nine signal output terminals 220 and two standby signal output terminals 240. The nine signal input terminals 120 are respectively connected to the nine signal output terminals 220. When a motherboard needs to be tested, a tester is connected to the connector 100 via the connector of the tester, and a plurality of test pins of the motherboard are respectively connected to a plurality of the signal output terminals 220, and then the tester will test the motherboard via the patch panel.
When a connecting line of the patch panel is broken, an extra connecting line is used to connect the unconnected input terminal 120 to a standby output terminal 240. However, with this method, the extra connecting line must be welded to the unconnected input terminal 120 and the standby output terminal 240, which is very inconvenient and may damage the patch panel.
What is needed is to provide a patch panel which overcomes the above problems.
SUMMARY
An embodiment of a patch panel includes a plurality of signal input terminals, an output module having a plurality of signal output terminals and at least one standby signal output terminal, and an adapter module having a slide board and a plurality of sliding blocks slidably mounted on the slide board. Each of the sliding blocks includes an electrical contact mounted thereon and connected to a corresponding signal input terminal. The slide board includes a plurality of electrical terminals mounted thereon and respectively connected to the signal output terminals of the at least one standby signal output terminal. The electrical contacts of the sliding blocks selectively electrically contact the electrical terminals of the slide board by sliding of the sliding blocks from an initial position to another position.
Other advantages and novel features of the present invention will become more apparent from the following detailed description of an embodiment when taken in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION
Referring to FIGS. 2 to 3, a patch panel in accordance with an embodiment of the present invention includes a connector 10, an output module 20, and an adapter module 30. The connector 10 includes nine signal input terminals 12. The output module 20 includes nine signal output terminals 22 and two standby signal output terminals 24a and 24b. The adapter module 30 includes a slide board 32 and nine sliding blocks 34. In other embodiments, the amount of the signal input terminals 12, the signal output terminals 22, the standby signal output terminals 24a and 24b, and the sliding blocks 34 can be changed according to need.
The sliding blocks 34 are slidably mounted on the slide board 32 side by side via a groove 33, which has a dovetail configuration (shown in FIG. 3). The right end of each slide block 34 includes an electrical contact “A” mounted thereon and connected to a corresponding signal input terminal 12 of the connector 10. The right side of the slide board 32 includes eleven electrical terminals “a” mounted thereon and respectively connected to the signal output terminals 22, and the standby signal output terminals 24a, 24b. In this embodiment, the slide board 32 defines a plurality of locating holes 36 therein. When the sliding blocks 34 are slidably moved on the slide board 32, the electrical contacts “A” of the sliding blocks 34 will electrically contact the electrical terminals “a” of the slide board 32, which can make the signal input terminal 12 electrically connect to the signal output terminals 22 or the standby signal output terminals 24a and 24b correspondingly.
In use, if all connecting lines of the patch panel are good, each of the sliding blocks 34 is located at an initial position on the slide board 32 (shown in FIG. 2). At this time, the signal input terminals 12 are respectively electrically connected to the signal output terminals 22 via the adapter module 30. And two locating posts 38 are respectively inserted into two corresponding locating holes 36 to locate the sliding blocks 34 on the slide board 32, and the patch panel works normally.
Referring also to FIG. 4, if one connecting line of the patch panel is broken, a corresponding slide block 34 is manually slid to another position to make the electrical contact “A” thereof electrically contact another electrical terminal “a” of the slide board 32 which connected to another signal output terminal 20. And the last positional block 34 of one end of the slide board 32 is slid to another position to make the electrical contact “A” thereof electrically contact another electrical terminal “a” of the slide board 32, which is connected to the standby signal output terminal 24a. And three locating posts 38 are respectively inserted into three corresponding locating holes 36 to locate the sliding blocks 34 on the slide board 32. Thereby, the patch panel can work normally again, which is very convenient.
Referring also to FIG. 5, if two connecting lines of the patch panel are broken, two corresponding sliding blocks 34 are manually slid to another position to make the electrical contacts “A” thereof electrically contact another electrical terminals “a” of the slide board 32 which connected to the another signal output terminals 20. And the last positional blocks 34 of two ends of the slide board 32 are slide to another position to make the electrical contacts “A” thereof electrically contact another electrical terminals “a” of the slide board 32 which respectively connected to the standby signal output terminals 24a and 24b. And four locating posts 38 are respectively inserted into four corresponding locating holes 36 to locate the sliding blocks 34 on the slide board 32. Thereby, the patch panel can work normally again, which is very convenient.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
