In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] As Figure 1 shown, there is a high-voltage connection piece signal export device for exporting the electrical signal on the high-voltage connection piece (2), including a magnetic adsorption module (3-1), a signal export module (3-2) and a test cable (3-3). The magnetic adsorption module (3-1) is arranged at both ends of the signal export module (3-2), the test cable (3-3) is connected to the signal export module (3-2), and the signal export module (3-2) is connected to the high-voltage connection piece (2).

[0034] In this embodiment, the high-voltage connection piece (2) is usually connected to the terminal in the cabinet to control the connection or disconnection of the circuit. It can be set in several groups and symmetrically installed on the mounting plate (1). The mounting plate (1) is made of a magnetically conductive plate. During testing, the mounting plate (1) is fixed on the cabinet. Each group of high-voltage connection pieces (2) includes 2 conductive posts (2-1) that are symmetrically arranged up and down. As Figures 1 - 3 shown, the 2 conductive posts (2-1) are connected or disconnected through a rotatable switching piece (2-2). When both ends of the switching piece (2-2) contact the two conductive posts (2-1) simultaneously, the high-voltage connection piece (2) is in a conducting state. As Figure 2 shown, and when the switching piece (2-2) rotates 90 degrees and separates from one of the conductive posts (2-1), the high-voltage connection piece (2) is disconnected and in a test state. As Figure 3 shown.

[0035] As Figure 6 shown, the signal export module (3-2) is the main structure of the high-voltage connection piece signal export device (3) and is used to realize the rapid export of the on-off signal between the signal export device (3) and the high-voltage connection piece (2) to be measured, including an insulating backing plate (3-2-1), a compression spring piece (3-2-2), an X-shaped spring piece (3-2-3), a U-shaped terminal (3-2-4), and a banana female head (3-2-5).

[0036] Specifically, the insulating backing plates (3-2-1) include two pieces, which are arranged symmetrically in parallel; an X-shaped spring piece (3-2-3) is arranged between the insulating backing plates (3-2-1), and the X-shaped spring piece (3-2-3) is fixed between the insulating backing plates (3-2-1) through a compression spring piece (3-2-2). The elastic deformation of the X-shaped spring piece (3-2-3) can be used to adjust the distance between the two insulating backing plates (3-2-1); a plurality of banana female connectors (3-2-5) are symmetrically arranged on the top surface of the insulating backing plates (3-2-1), and U-shaped terminals (3-2-4) matching the banana female connectors (3-2-5) are also symmetrically arranged on the bottom surface of the insulating backing plates (3-2-1). The U-shaped sockets at one end of the U-shaped terminals (3-2-4) all face outward, that is, in the direction of the high-voltage connection piece (2), and are used to be clamped on the conductive posts (2-1) of the high-voltage connection piece (2), and the other ends are fixed on the bottom surface of the insulating backing plates (3-2-1) and are connected to the banana female connectors (3-2-5) of the test cable (3-3), so that the on-off signal on the high-voltage connection piece (2) can be transmitted to the banana female connectors (3-2-5); guiding grooves (3-2-1-1) are respectively arranged at both ends of the insulating backing plates (3-2-1) for installing the magnetic adsorption module (3-1).

[0037] As Figures 4 - 5 shown, the magnetic adsorption module (3-1) is used to realize the installation between the signal export device (3) and the high-voltage connection piece to be measured, and includes a magnetic conductive plate (3-1-1), a lower magnetic block (3-1-2), a magnetic isolation plate (3-1-3), a knob seat (3-1-4), a knob (3-1-5), an upper magnetic block (3-1-6), a guiding plate (3-1-8), and a stopper (3-1-10).

[0038] Specifically, the magnetic conductive plates (3-1-1) are arranged symmetrically left and right, the magnetic isolation plates (3-1-3) are symmetrically installed in front of and behind the magnetic conductive plates (3-1-1) respectively. A lower magnetic block (3-1-2) is arranged on one side between the two magnetic conductive plates (3-1-1), and the N / S magnetic pole directions of the lower magnetic block (3-1-2) face the two magnetic conductive plates (3-1-1) respectively. A knob seat (3-1-4) is arranged on the other side of the magnetic conductive plates (3-1-1) and the magnetic isolation plates (3-1-3). A knob (3-1-5) is installed on the knob seat (3-1-4), and an upper magnetic block (3-1-6) is embedded inside the knob (3-1-5), which is arranged in parallel with the lower magnetic block (3-1-2) to ensure that the N / S magnetic pole directions of the two are opposite or the same. The knob (3-1-5) can rotate 180°, and then drive the N / S magnetic pole direction of the upper magnetic block (3-1-6) to be opposite or the same as the N / S magnetic pole direction of the lower magnetic block (3-1-2). The overall magnetic force of the magnetic adsorption module (3-1) is controlled through the cooperation of the lower magnetic block (3-1-2) and the upper magnetic block (3-1-6).

[0039] When the N / S magnetic poles of the upper magnetic block (3-1-6) and the lower magnetic block (3-1-2) are in the same direction, the magnetic forces of the two are superimposed, such as Figure 8 As shown, the magnetic adsorption module (3-1) has the greatest adsorption force on the mounting plate (1) made of a magnetic conductive plate, and when the N / S magnetic pole directions of the upper magnetic block (3-1-6) and the lower magnetic block (3-1-2) are in opposite directions, the magnetic forces of the two are offset, as shown in FIG. Figure 9 As shown, the adsorption force of the magnetic adsorption module (3-1) on the mounting plate (1) made of magnetic conductive sheet material is 0.

[0040] In addition, the magnetic isolation plate (3-1-3) on one side is connected to the guide plate (3-1-8) via a first screw (3-1-7), and the guide plate (3-1-8) is parallel to the lower magnetic block (3-1-2) and can be used to insert into the guide grooves (3-2-1-1) at both ends of the insulating pad (3-2-1). The end of the guide plate (3-1-8) is connected to the stopper (3-1-10) via a second screw 3-1-9, which plays a limiting role after the guide plate (3-1-8) is inserted.

[0041] like Figure 7 As shown, the main body of the test cable (3-3) is a multi-core cable (3-3-2), one end of the multi-core cable (3-3-2) is connected to a banana male connector (3-3-1) for connecting to a banana female connector (3-2-5), and the other end is connected to an electrical connector (3-3-3) for converging the on / off signals to be tested for subsequent testing needs.

[0042] The working process of a high-voltage connecting piece signal deriving device described in this embodiment is as follows:

[0043] (1) Adjust the switch piece (2-2):

[0044] When the on / off state of the high-voltage connecting piece (2) needs to be tested, the switching piece (2-2) is rotated to the testing state, such as Figure 3 shown.

[0045] (2) Install the signal export module (3-2):

[0046] The high-voltage connecting piece signal exporting device (3) is held in hand, the insulating pad (3-2-1) is pressed, and the X-shaped spring piece (3-2-3) is thereby compressed, so that the U-shaped terminal (3-2-4) of the signal exporting module (3-2) is located between the high-voltage connecting pieces (2), the U-shaped terminal (3-2-4) is aligned with the conductive column (2-1) to be measured, the insulating pad (3-2-1) is released, and the X-shaped spring piece (3-2-3) rebounds, so that the U-shaped terminal (3-2-4) reliably contacts the conductive column (2-1) to be measured under the action of elastic force.

[0047] (3) Install the magnetic adsorption module (3-1):

[0048] Insert the guide plate (3-1-8) of the magnetic adsorption module (3-1) into the guide grooves (3-2-1-1) at both ends of the insulating backing plate (3-2-1), and rotate the knob (3-1-5) to make the N / S magnetic pole directions of the upper magnetic block (3-1-6) and the lower magnetic block (3-1-2) the same. As Figure 8 shown, the magnetic lines of force of the lower magnetic block (3-1-2) start from the N pole, pass through the mounting plate (1), and reach the S pole of the lower magnetic block (3-1-2), so that the high-voltage connection piece signal export device (3) of this embodiment is reliably adsorbed on the mounting plate (1).

[0049] (4) Complete the signal export of the high-voltage connection piece (2):

[0050] The test signal on the high-voltage connection piece (2) is transmitted to the banana female head (3-2-5) through the U-shaped terminal (3-2-4). The banana female head (3-2-5) cooperates with the banana male head (3-3-1), and the test signal is converged to the electrical connector (3-3-3) through the multi-core cable (3-3-2) to complete the signal export of the high-voltage connection piece (2).

[0051] (5) Disassemble the entire high-voltage connection piece signal export device:

[0052] Rotate the knob (3-1-5) to make the N / S magnetic pole directions of the upper magnetic block (3-1-6) and the lower magnetic block (3-1-2) different. As Figure 9 shown, the magnetic lines of force of the upper magnetic block (3-1-6) and the lower magnetic block (3-1-2) are mutually closed-loop, and there is no magnetic force between the lower magnetic block (3-1-2) and the mounting plate (1). After disassembling the magnetic adsorption module (3-1), press the insulating backing plate (3-2-1) to compress the X-shaped spring piece (3-2-3) to separate the U-shaped terminal (3-2-4) from the conductive column to be measured (2-1), and finally disassemble the signal export module (3-2) from the high-voltage connection piece (2).

[0053] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
