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.

As shown in FIG. 1 , a test adapter board includes a connector 100 and an output module 200. The output module 200 includes a plurality of signal output terminals 220 and a plurality of alternate signal output terminals 240. Each signal input pin 120 of the device 100 is connected to a signal output terminal 220. When testing the printed circuit board, a tester is usually connected to the connector 100 through a connector, and the test pin of the printed circuit board is correspondingly connected to the signal output terminal 220, and the tester is turned on. The printed circuit board can then be tested.

If a certain connection line in the adapter board is broken, it is common practice to find another connection line and solder one end thereof to the signal input pin 120 of the connector 100 connected to the damaged connection line. Then, the other end of the connection line is connected to the standby signal output terminal 240, and then the standby signal output terminal 240 is connected to the corresponding test pin of the printed circuit board to be tested again. However, this type of maintenance requires a re-welding step, which wastes time and may cause a transfer due to a welding error. The board is damaged and very inconvenient.

In view of the above, it is necessary to provide an interposer that facilitates the connection of the pins of the connector connected to the breakage connection line to the alternate signal output terminal.

An adapter board includes a plurality of signal input pins, an output module, a sliding plate and a plurality of sliding blocks slidably mounted on the sliding plate, the output module comprising a plurality of signal output terminals and at least one standby signal output Each of the sliding blocks is provided with an electrical contact, and each of the electrical contacts is electrically connected to a corresponding signal input pin, and the sliding plate is provided with a plurality of electrical terminals corresponding to the electrical contacts. The electrical terminals are electrically connected to the signal output terminals and the standby signal output terminals, and the electrical contacts are selectively electrically connected to the electrical terminals through the sliding of the sliding blocks.

Compared with the prior art, when the connecting board is damaged, the sliding line of the corresponding sliding board can be selectively replaced by the sliding signal to be connected to the standby signal output terminal without using the re The welding method is replaced, which saves time and prevents the damage of the adapter plate due to welding errors, and the operation is also very convenient.

Referring to FIG. 2 to FIG. 5 , a preferred embodiment of the adapter board of the present invention includes a connector 10 , an output module 20 , and a switching module 30 . The connector 10 includes nine signal input pins. The output module 20 includes nine signal output terminals 22 and two alternate signal output terminals 24 . The adapter module 30 includes a sliding plate 32 and nine sliding blocks 34 . The number of the signal input pin 12, the signal output terminal 22, the standby signal output terminal 24, and the sliding block 34 of the connector 10 can be increased or decreased according to actual design requirements, and is not limited to the number listed in the embodiment. The connector 10 is used for conveniently connecting to the tester, and can also be deleted, and the signal input pin 12 can be directly disposed at an appropriate position on the transfer board.

The sliding blocks 34 are slidably mounted on the sliding plate 32. Each sliding block 34 can slide on the sliding plate 32. In the embodiment, the sliding plate 32 slides through the dovetail structure and the sliding blocks 34. Connected (as shown in FIG. 5), it can also be slidably connected to the sliding blocks 34 through other structures having the same function.

Each of the sliding blocks 34 is provided with an electrical contact A, and each of the electrical contacts A is connected to a corresponding signal input pin 12 of the connector 10 through the interior of the corresponding sliding block 34. There are eleven electrical terminals a on the right side of the 32, and the eleven electrical terminals a are electrically connected to the nine signal output terminals 22 and the two standby signal output terminals 24, respectively. When the sliding block 34 slides on the sliding plate 32, the electrical contacts A can be electrically contacted with the electrical terminals a to realize the signal input pins connected to the electrical contacts A. 12 is electrically connected to the signal output terminal 22 or the alternate signal output terminal 24 connected to the electrical terminals a. Wherein, the electrical contact between the electrical contact A and the electrical terminal a can also be connected by using a male/female electrical connector, such as The electrical contacts A can be male electrical connectors, and the electrical terminals a can be corresponding female electrical connectors to make electrical contact between the two better, and can also pass other functions having the same function. The structure is implemented.

In this embodiment, a plurality of positioning holes 36 are correspondingly disposed on the sliding plate 32. When the sliding blocks 34 are moved to a certain position, the corresponding positioning holes 36 are inserted into the positioning pins 38 to position the sliding blocks 34. On the sliding plate 32. The sliding plate 32 and the sliding blocks 34 can also be connected by an interference fit without using the positioning holes 36 and the positioning pins 38, and can also be realized by other structures having the same function.

When the connecting board is not damaged, the sliding blocks 34 are in an initial position (as shown in FIG. 2), and the electrical contacts A on the sliding blocks 34 are respectively input and the signals are input. The electrical terminal a connected to the pin 12 is electrically connected. At this time, the electrical terminal a connected to the standby signal output terminal 24 is in an empty state, and the adapter plate can be used normally.

When a certain connecting line in the adapter board (such as the connecting line connected to the second signal output terminal 22) is damaged, a corresponding sliding block 34 is slid on the sliding plate 32 (as shown in FIG. 4). The electrical contact A is electrically connected to the electrical terminal A connected to the connecting line adjacent to the damaged connecting line. At this time, the adapter plate can be used normally. If other cables are also damaged, the same method can be used for replacement, and will not be described again. The application of the adapter plate of the invention can avoid the step of re-welding when the connection line is damaged, and also saves time and improves efficiency.
