The first conductive line 40 and the second conductive line 50 are made of conductive material, so that the connection points formed by the contact points on the conductive lines are communicated with each other. The number of the conducting lines on the bottom plate 10 and the top plate 20 may be set as required, for example, four or five conducting lines, which is not limited in this embodiment.

Each contact in the contact array 30 is also made of a conductive material, and each contact is provided with a portion, such as a jack or the like, for connecting to a pin of a test element; the test element comprises components such as a resistor, a capacitor and the like.

After the test element is connected to the contact, the test element may be connected to the first conductive line 40 and the second conductive line 50 corresponding to the contact through the contact, so as to be connected to the test element connected to the other contact on the first conductive line 40 or the second conductive line 50. According to different arrangement relations of pins of the test elements on each conducting wire, the two test elements can form a parallel connection or series connection relation, so that wiring among the test elements can be reduced, and a test circuit is simplified.

In order to make the circuit layout of the test circuit more flexible, the directions of the conducting lines on the bottom board 10 and the top board 20 may be different, for example, the bottom board 10 may be provided with a conducting line parallel to one side, a conducting line perpendicular to the side, and a conducting line intersecting the side.

Of course, to make the circuit simpler, the directions of the conducting lines on the bottom plate 10 and the top plate 20 may be the same; that is, the first conductive lines 40 are disposed in parallel on the bottom board 10 along the first direction; the second conductive lines 50 are disposed in parallel in the second direction on the top plate 20. The first direction and the second direction can be set according to the user requirement.

In addition, in order to facilitate the arrangement of the contact array, the contacts are uniformly distributed, the operation is convenient, and the first direction and the second direction are mutually perpendicular. In a specific implementation, for each conductive line to facilitate printing, each first conductive line 40 on the bottom plate 10 is distributed in a longitudinal direction as shown in fig. 2, and each second conductive line 50 on the top plate 20 is distributed in a transverse direction as shown in fig. 3.

Referring again to fig. 2, 3 and 4, fig. 4 is a front view of a second embodiment of the bread board according to the present invention. Based on the first embodiment described above, the present invention proposes a second embodiment of a bread board.

The first connection end of the conducting member 80 is connected to the first end of the first switch 60, the second connection end of the conducting member 80 is connected to the first end of the second switch 70, the third connection end of the conducting member 80 is connected to the test element, the second end of the first switch 60 is connected to the first conducting wire 40, and the second end of the second switch 70 is connected to the second conducting wire 50.

In order to improve the convenience of the bread board in adjusting the circuit, in this embodiment, the contacts include the first switch 60, the second switch 70, and the conductive member 80. The conductive member 80 is made of conductive material, and the conductive member 80 is provided with a jack for connecting pins of the test element.

The test element is connected by inserting pins into receptacles in the pass-through 80, the test element being in communication with the first pass-through line 40 when the first switch 60 is closed; when the second switch 70 is closed, the test element communicates with the second conductive line 50. When a tester modulates the circuit route, the connection relation between the test elements can be adjusted by controlling the closing states of the first switch 60 and the second switch 70, so that the adjustment of the test elements is reduced.

In a specific implementation, the first switch 60 or the second switch 70 may be an electrically controlled switch or a manually controlled switch, and after the test element is plugged into each conducting member 80, the test personnel controls the first switch 60 or the second switch 70 to be turned on or off, so as to adjust the circuit line to a required line, and the specific configuration of the first switch 60 or the second switch 70 may be set according to the requirement, which is not limited in this embodiment.

In order to clearly describe the control of the first switch 60 or the second switch 70, the present embodiment will be described taking the first switch 60 or the second switch 70 as an electrically controlled switch as an example.

In this embodiment, the bread board further includes a control circuit, and the third terminal of the first switch 60 and the third terminal of the second switch 70 are both connected to the output terminal of the control circuit. And the control circuit is used for outputting a control signal to the first switch 60 and/or the second switch 70 so as to control the on-off of the first switch 60 and/or the second switch 70.

In a specific implementation, a processor may be disposed in the control circuit, and the processor outputs control information to the first switch 60 or the second switch 70 through a preset control program, where the control signal may be a low level signal or a high level signal. The first switch 60 or the second switch 70 may be closed when a low level signal is received, or may be closed when a high level signal is received.

For control, the first switch 60 is a MOS transistor electronic switch, a control end of the MOS transistor electronic switch is connected to an output end of the control circuit, a first connection end of the MOS transistor electronic switch is connected to a first conductive line on the bottom plate, and a second connection end of the MOS transistor electronic switch is connected to a second conductive line on the top plate.

Similarly, the second switch 70 may be a MOS transistor electronic switch. The MOS transistor electronic switch is an integrated device, and may implement physical connection between the conducting element 80 and each conducting line, where the logic control level of the closing and conducting is related to its specific model, which is not limited in this embodiment.

Referring to fig. 5, fig. 5 is a functional schematic diagram of an embodiment of a bread board control circuit according to the present invention.

As shown in fig. 5, the control circuit includes a microcontroller 90 and a plurality of displacement buffers 100, the microcontroller 90 is respectively connected to each of the displacement buffers 100, and the displacement buffers 100 are connected to the first switch 60 and/or the second switch 70. The displacement buffer 100 is configured to convert the control signal sent by the microcontroller 90 into a driving signal, and control the on/off of the first switch 60 and/or the second switch 70 according to the driving signal.

It should be noted that, the control signal and the driving signal may be current signals, and the output current of the microcontroller 90 is low, so that the control current of the first switch 60 or the second switch 70 is difficult to reach, and therefore, the displacement buffer 100 is provided to amplify the control current, so as to obtain the driving current meeting the requirement.

In addition, when the number of the first switches 60 and the second switches 70 is large, the number of control pins of the single microcontroller 90 is insufficient, and the control pins need to be extended by the displacement buffer 100, so that all the first switches 60 and the second switches 70 are controlled. The microcontroller 90 inputs the bit data to be input to the data input of the shift register 100; the shift register 100 strings in data; and then parallel output data, namely data merging, is realized according to the control sequence.

To facilitate adjustment of the control program, the control circuit further includes a communication circuit 110, the communication circuit 110 being coupled to the microcontroller 90; the microcontroller 90 is configured to generate a control signal according to the control information sent by the communication circuit 110.

It should be noted that the communication circuit 110 may employ a conventional communication interface, such as SCI (Serial Communication Interface ), SPI (Serial Peripheral Interface, serial peripheral interface), or others. The communication circuit 110 may receive the control information from the external device and forward the control information to the microcontroller 90, and the microcontroller 90 generates corresponding control information by compiling the control information.

In specific implementations, the first switch 60 or the second switch 70 may be numbered in advance, such as 01, 02, 03, or the like; and simultaneously, the control state is coded, for example, the closing state is 00, and the opening state is 01. The external device generates information of the protection switch number and the state number according to the need, and transmits the generated signals to the microcontroller 90, so that the microcontroller 90 determines the control strategy for each switch.

In the second embodiment, the contacts include the first switch 60, the second switch 70 and the conducting member 80, each of which is driven by the control circuit, and the tester can modify by changing the state of the switch when adjusting the circuit, so that the adjustment of the test element is reduced, and the test is more convenient.
