[0032] Combine Figures 1 to 5 As shown, a switch adjustment control box for a test device provided by the present invention includes a switch 1 , a power supply 2 , a device under test 3 and a series block 4 .

[0033] Combine Figures 1 to 5 As shown, the switch 1 is connected in series between the power supply 2 and the device under test 3; four series interfaces are provided on the series block 4, and multiple series blocks 4 are slidably assembled on the switch 1; a circuit is provided in the switch 1, and one series block 4 is connected in series in the circuit, and multiple series blocks 4 are slidably switched and connected in series in the circuit, and two series interfaces on the same side of the series block 4 are connected to the power supply 2, and the other two series interfaces are connected to the device under test 3; during use, the four series interfaces on multiple series blocks 4 are connected in series in at least two ways.

[0034] In this embodiment, the series block 4 is connected in series between the power supply 2 and the device under test 3. Different wiring methods on the multiple series blocks 4 correspond to different measurement schemes. The multiple series blocks 4 are connected in series in the circuit by sliding on the switch 1 to switch different series blocks 4, thereby realizing simple and fast switching of the circuit.

[0035] In some embodiments, combined Figure 1 As shown, the two series interfaces on the same side of the series block 4 are simultaneously connected in series with the positive and negative poles of the power supply 2, and the outer two series interfaces are connected to the positive and negative poles of the device under test 3. The two series interfaces on the same side are respectively connected to the other two series interfaces. This is the first connection method of the switch 1. Each series block 4 corresponds to a wiring method, and the circuit switching is achieved by replacing the entire series block 4.

[0036] In some embodiments, combined Figure 1 、 Figure 2As shown, the switch 1 is cylindrical, and an annular groove is provided on the cylindrical surface of the switch 1. Multiple series blocks 4 are slidably assembled in the annular groove. The series blocks 4 together form a ring. Compared with the parallel series blocks 4 slidingly assembled in the horizontal groove, the process of switching the series blocks 4 is smoother.

[0037] In some embodiments, combined Figure 3 As shown, the two series interfaces on the same side of the series block 4 are connected in series with the other two series interfaces through two wires 41, and the two wires 41 are parallel. This is a wiring method of the series interfaces on the series block 4, and the circuit is conductive and the positive and negative directions of the circuit remain unchanged.

[0038] In some embodiments, combined Figure 4 As shown, the two series interfaces on the same side of the series block 4 are connected in series with the other two series interfaces through two wires 41, and the two wires 41 cross. This is the second wiring method of the series interfaces on the series block 4. The circuit is conductive and the positive and negative poles of the circuit are interchanged.

[0039] In some embodiments, combined Figure 2 As shown, the two serial interfaces on the same side of the serial block 4 are disconnected from the other two serial interfaces through two wires 41 . This is the third wiring method of the serial interfaces on the serial block 4 , and the circuit is disconnected.

[0040] In some embodiments, combined Figure 5 As shown, there are two switches 1, and the two switches 1 are respectively connected in series between the positive and negative poles of the power supply 2 and the positive and negative poles of the device under test 3. A series block 4 is slidably assembled on one switch 1. The four series interfaces on the series block 4 are divided into two pairs. The two pairs of series interfaces are connected in two ways. Sliding and switching a pair of series interfaces are connected in series between the power supply 2 and the device under test 3. This is the second connection method of the switch 1. The two pairs of series interfaces on each series block 4 correspond to two wiring methods. A series block 4 switches the two pairs of series interfaces by sliding, which can realize the change of a single line and connect other components in series in the line.

[0041] In some embodiments, combined Figure 5 As shown, a pair of the series interfaces on the series block 4 are connected in series via a wire 41, and the other pair of the series interfaces are disconnected. This is one of the wiring methods that can switch a single line between on and off.

[0042] In some embodiments, combined Figure 5As shown, the switch adjustment control box of the test device also includes an external adjustment element 5, which is connected in series between a pair of the series interfaces, and another pair of the series interfaces are connected in series through a wire 41. The external adjustment element 5 can be an electronic component such as an ammeter and a second power supply. The ammeter can measure the circuit current through the series connection, and the second power supply can change the circuit voltage through the series connection to realize the test process; this wiring method can realize the switching of the series state of the external adjustment element 5.

[0043] In some embodiments, combined Figure 6 As shown, the power supply 2 is a three-phase power supply, and the number of series interfaces on the series block 4 is six. The three-phase power supply has three live wires, which is different from the common circuit. However, when the number of lines changes, the number of series interfaces on the series block 4 must also be changed synchronously to adapt to the new circuit.

[0044] Working process: The switch 1 is connected in series between the power supply 2 and the device under test 3, and the series block 4 is connected in series in the internal circuit of the switch 1. Multiple series blocks 4 are slidably assembled on the switch 1. By sliding, one series block 4 can be selected to be connected in series in the circuit. The wiring methods between the series interfaces on the multiple series blocks 4 are different, but when the series block 4 is switched, the circuit between the power supply 2 and the device under test 3 changes.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
