Referring to fig. 1 to 3, the present embodiment provides a circuit board structure of a load test lamp panel, including a circuit board body 1 and a power interface 2, where the power interface is disposed on the circuit board body, a plurality of load resistors 3 are disposed on a front inner region of the circuit board body, a plurality of sockets 4 for connecting an external controller are disposed on a front side edge region of the circuit board body, two pins of the load resistors penetrate through the circuit board body and are welded on a back surface of the circuit board, a plurality of pins of the sockets penetrate through the circuit board body and are welded on the back surface of the circuit board, and a plurality of driving LED lamps 5 for indicating are disposed on the back surface of the circuit board body. The power interface is connected with the power pins of the socket through the leads on the circuit board body, as shown in fig. 3, the power interface P101 is connected with the power pins (24V and GND) of the socket P201. The lead on the circuit board body is a copper foil lead on the printed circuit board, and the connection of different elements is realized. The driving pin (such as pin 10 of P201 in fig. 3) of the socket is connected with the driving LED lamp (such as LED201 in fig. 3) through a lead on the circuit board body, the driving LED lamp is connected to the power interface through a lead on the circuit board body, and the load resistor (such as R203 in fig. 3) is connected in parallel with the driving LED lamp.
The utility model discloses when testing, at first insert the transmission controller on the socket. Meanwhile, an external direct current power supply (such as a 24V direct current power supply) is connected to the power interface of the utility model. Can realize external power source's access through power source, through the socket, can realize being connected of circuit and derailleur controller, the derailleur controller can arrive signal transmission like this the utility model discloses a lamp plate circuit is last. By driving the LED lamp, the control condition of the transmission controller can be intuitively seen, such as whether the control is normal or not. The analog load module can realize the analog load output of the controller. Meanwhile, the areas of the circuit boards are fully utilized by respectively arranging the load resistors on the front side and the back side of the circuit board and driving the LED lamps, and the aging test of a plurality of controller interfaces can be realized on one circuit board by arranging a plurality of sockets. The test condition of the controller can be conveniently seen through the load resistor and the driving LED lamp.
For different output conditions of the external transmission controller, high-side driving and low-side driving are included. The socket to which it is connected includes a high level output pin and a low level output pin. To enable testing of these two different pins, the pins should be connected to the driving LED lamp differently. Specifically, the driving pin of the socket includes a high-level output pin (e.g., pin 10 of socket P201 in fig. 3), the high-level output pin is connected to a positive electrode of a driving LED lamp (e.g., LED201 in fig. 3) through a lead on the circuit board body, and a negative electrode of the driving LED lamp is connected to a negative electrode of the power interface through a lead on the circuit board body. Therefore, the corresponding driving LED lamp can be lightened when high-level output is carried out. In another case, the driving pin of the socket includes a low-level output pin (e.g., pin 26 of socket P201 in fig. 3), the low-level output pin is connected to the cathode of the driving LED lamp (e.g., LED226 in fig. 3) through a lead on the circuit board body, and the anode of the driving LED lamp is connected to the anode of the power interface through a lead on the circuit board body.

Specifically, the driving pins of the socket include more than two high-level output pins (such as the 14 pin and the 16 pin of the socket P201 in fig. 3), each high-level output pin is separately connected with an anode of a diode (such as the 14 pin connected with a diode D204, such as the 16 pin connected with a diode D205), cathodes of all the diodes are connected with one end of a load resistor (such as R203 in fig. 3), and the other end of the load resistor is connected with a cathode of the power interface, and the diodes are arranged on the back of the circuit board body. When the high-level pin outputs, current can flow through the load resistor after passing through the diode, and load driving of the high-level pin is achieved. In another case, the driving pins of the socket include more than two low-level output pins (such as pins 26 and 28 of the socket P201 in fig. 3), each low-level output pin is separately connected with the cathode of a diode (such as pin 26 connected with the diode D219, and such as pin 28 connected with the diode D221), the anodes of all the diodes are connected with one end of a load resistor (such as R285 in fig. 3), the other end of the load resistor is connected with the anode of the power interface, and the diodes are arranged on the back of the circuit board body. Therefore, when the low-level pin outputs, current can flow through the diode after passing through the load resistor, and load driving of the low-level pin is achieved.
In order to realize the current limiting of the circuit and avoid the circuit from being burnt by excessive current, the positive electrode of the power interface is connected with the positive electrode of the power pin of the socket through a fuse 6 (such as F209 in fig. 3) arranged on the front surface of the circuit board body.
