Description

Adapter plate

The present invention relates to an adapter plate.

Generally, after the wiring is completed or after the electronic components are assembled, in order to determine that each line can be normally turned on, it is usually necessary to test, or after each electronic component is fixed on the printed circuit board, the signal test is performed. IC chips also need to be tested on their individual pins to determine if each pin is working properly.

1 is a conventional test adapter board including an input connector 10 and an output module 20, the input connector 10 is a 24Pin DSUB (pin cable head) connector, and the output module 20 includes two groups. The signal output terminals CN1 and CN2, the two sets of signal output terminals CN1 and CN2 each include 12 signal output terminals, and each pin of the DSUB connector is respectively connected as a signal input terminal to a signal output terminal. When testing a printed circuit board, the circuit is usually connected to the 24Pin DSUB connector through a connector, and a test signal is input to the printed circuit board, and then the signals of the 24 signal output terminals are detected one by one. Know if the circuit of the printed circuit board under test is normally turned on.

If a certain connecting line in the adapter board is broken or a signal output terminal fails due to external force and other factors, the adapter board needs to be repaired or the adapter board replaced and re-wired, which is a waste of time and a waste of time. .

In view of the above, it is necessary to provide an adapter board that can easily transfer the signal of the failed signal output terminal to other normally working signal output terminals to correctly measure whether each line or each pin outputs a normal signal.

An adapter board includes a plurality of signal input terminals, a plurality of signal output terminals connected to the signal input terminals, a plurality of jumper connectors, and a standby signal output terminal, wherein each of the signal input terminals corresponds to a jump The first end of the line connector is connected, and the second end of the jumper connector is connected to the standby signal output terminal.

Compared with the prior art, the foregoing adapter board can connect the two ends of the jumper connector when a certain connection line is broken or a certain signal output terminal fails due to external forces and the like, thereby disabling the signal output terminal. The signal is transferred to the alternate signal output terminal. The adapter board only needs to add a jumper connector and a standby signal output terminal on the conventional adapter board, which is low in cost and saves time and cost.

Referring to FIG. 2 to FIG. 4 together, a preferred embodiment of the adapter board of the present invention includes an input connector 100, an output module 200, and 24 jumper connectors JP1-JP24. The input connector 100 includes 24 Signal input terminals IN1-IN24, the input connector 100 can It is considered that a 24Pin DSUB connector can also be other types of connectors. The output module 200 includes 24 signal output terminals OUT1-OUT24 and 6 alternate signal output terminals RO1-RO6, and the 24 signal output terminals OUT1-OUT24 are divided into two. Two sets of signal output terminals CN1 and CN2, wherein the two sets of signal output terminals CN1 and CN2 each include 12 signal output terminals, and the six standby signal output terminals RO1-RO6 are divided into two sets of standby signal output terminals RCN1 and RCN2, wherein The two sets of alternate signal output terminals RCN1 and RCN2 each include three alternate signal output terminals. This embodiment is described by taking only 24 signal input terminals IN1-IN24 as an example. Other adapter plates containing different numbers of signal input terminals can be designed according to this embodiment.

3 and 4 are internal circuit diagrams of Fig. 2. The adapter plate comprises two upper and lower plates, wherein FIG. 3 is an internal circuit diagram of the upper layer, and FIG. 4 is an internal circuit diagram of the lower layer.

In the upper board, the 24 signal input terminals IN1-IN24 are connected to the 24 signal output terminals OUT1-OUT24 by a connecting line in a one-to-one manner.

In the lower board, one of the 24 jumper connectors JP1-JP24 is respectively connected to the 24 signal input terminals IN1-IN24, and the first, second, third and fourth jumper connectors JP1-JP4 are respectively connected. One end is connected to the first standby signal output terminal RO1, and the other ends of the fifth, sixth, seventh and eighth jumper connectors JP5-JP8 are connected to the second standby signal output terminal RO2, and so on, that is, every four The other end of the jumper connector is connected to an alternate signal output terminal.

During the test, if the connection line between the signal input terminal IN1 and the signal output terminal OUT1 of the adapter plate is broken or the signal output terminal OUT1 is damaged, the user can directly connect the two ends of the jumper connector JP1. , making the signal input terminal IN1 The signal output terminal RO1 is connected to the standby signal output terminal RO1, so that the user does not need to repair or replace the entire adapter board, saving time and cost, and other signal input terminals. If the connection line between the signal output terminal and the signal output terminal is broken or the other signal output terminals are damaged, it can be handled in the same way.

The number of the signal input terminal, the signal output terminal, the standby signal output terminal and the jumper connector of the adapter plate can be changed according to the needs of the designer, as long as the number of the signal input terminals is satisfied, and the signal output terminal is The number and the number of jumper connectors are equal. For example, in the foregoing embodiment, only one spare signal output terminal RO1 may be used, and the first ends of the 24 jumper connectors JP1-JP24 are respectively connected to the 24 signal input terminals, and the 24 jumper connectors are connected. The second end of JP1-JP24 is connected to the standby signal output terminal RO1. At this time, only when the adapter board has only one connection line broken or only one signal output terminal fails, the replacement need not be replaced. Board to complete the test. At the same time, 24 spare signal output terminals RO1-RO24 may be used, and the first ends of the 24 jumper connectors JP1-JP24 are correspondingly connected to the 24 signal input terminals, and the second end corresponds to the 24 The alternate signal output terminals RO1-RO24 can be connected. In this case, no matter how many connection lines of the adapter board are broken or how many signal output terminals are invalid, the test can be completed without replacing the adapter board. If the designer considers the cost and the adapter board does not have multiple cable breaks at the same time or multiple signal output terminals fail, fewer spare signal output terminals can be used; instead, more spare signal output terminals can be used. .

The adapter plate can connect the two ends of the jumper connector by a jumper cap when a certain cable breakage or a certain signal output terminal fails due to external force and other factors. The signal input terminal connected to the failed signal output terminal can be connected to the standby signal output terminal, thereby transferring the signal of the failed signal output terminal to the standby signal output terminal. The adapter board of the present invention only needs to add a jumper connector and a standby signal output terminal on the conventional test adapter board, and the cost is low, and time and cost can be saved.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
