[0039] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0040] Example 1

[0041] like Figure 1-Figure 5 As shown, the present invention provides an intelligent testing device for a circuit breaker, comprising:

[0042] Detector 1, which is a circuit breaker characteristic tester and is used for characteristic testing of circuit breaker 2;

The circuit breaker positioning and clamping module 3 includes a U-shaped fixing member 4 and a clamping plate 5 slidably arranged in the fixing member 4. A spring 6 is arranged between one side of the clamping plate 5 and the fixing member 4. The other side of the clamping plate 5 cooperates with an inner wall of the fixing member 4 to form a clamping structure for clamping the circuit breaker 2.

Through the cooperation of the clamping plate 5 and the fixing member 4, the circuit breakers 2 of different widths can be clamped. The guide inclined plate 7 is provided to play a guiding role when installing the circuit breaker 2. When the circuit breaker 2 is pressed on the guide inclined plate 7, the clamping plate 5 will be driven to move, so that the circuit breaker 2 can be easily installed between the clamping plate 5 and the fixing member 4. The depth adjustment plate 8 is provided for the installation and positioning of the circuit breaker 2, so as to adjust the height of the wiring hole on the circuit breaker 2 when the circuit breaker 2 is installed on the circuit breaker positioning clamping module 3.

[0044] The automatic wiring module 10 is used to wire the circuit breaker 2 so as to electrically connect the circuit breaker 2 and the detector 1. The automatic wiring module 10 is provided with two groups, which are respectively located on both sides of the circuit breaker positioning and clamping module 3. The automatic wiring module 10 specifically includes an elastic electrical connector 11 and a two-stage driving structure 12 for driving the elastic electrical connector 11. The elastic electrical connector 11 is electrically connected to the detector 1. The two-stage driving structure 12 includes a sliding plate 14 that can slide toward the circuit breaker positioning and clamping module 3 and a power component 15 for driving the sliding plate 14 to slide back and forth. The power component 15 is an electric telescopic rod. A guide sleeve 16 is installed on the sliding plate 14. A sliding rod 17 is slidably sleeved in the guide sleeve 16. A baffle 18 that can slide with the sliding rod 17 is fixedly provided at one end of the sliding rod 17 that is away from the circuit breaker positioning and clamping module 3. The sliding rod 17 moves toward the circuit breaker positioning and clamping module 3. The elastic electrical connector 11 is installed at one end of the module 3. The elastic electrical connector 11 includes an elastic member 19 with an overall U-shaped structure. The opening of the elastic member 19 is arranged toward the sliding rod 17. Both sides of the elastic member 19 are in a curved shape that is arched on the side facing away from the sliding rod 17. An electrical connecting piece 20 is fixedly provided on the outer side of the middle position of the arched part on both sides of the elastic member 19. The side of the electrical connecting piece 20 facing away from the elastic member 19 is a rough structure. A ring 21 is fixedly provided between the two sides of the opening of the elastic member 19. The ring 21 is slidably sleeved on the sliding rod 17 and the ring 21 is fitted with the guide sleeve 16 when the elastic electrical connector 11 is not deformed; a fixed stopper 22 for blocking the stopper 18 is provided on the sliding path of the stopper 18; a base 23 is fixedly connected to the fixed stopper 22, the tail end of the electric telescopic rod is rotatably connected to the base 23, and the sliding plate 14 is slidably arranged on the base 23. The elastic electrical connector 11 and the slide bar 17 are both made of conductive materials. The slide bar 17 is electrically connected to the detector 1 , thereby making the elastic electrical connector 11 electrically connected to the detector 1 .

[0045] like Figure 6 As shown, when the two-stage drive structure 12 performs the first stage drive, the power component 15 drives the sliding plate 14 to slide toward the circuit breaker positioning clamping module 3. At this time, the guide sleeve 16, the collar 21, the elastic electrical connector 11, the slide rod 17, and the baffle 18 slide together with the sliding plate 14 until the baffle 18 fits with the fixed baffle 22 and drives the elastic electrical connector 11 to extend into the wiring hole of the circuit breaker 2, so that the elastic electrical connector 11 moves into place. Figure 7As shown, when the two-stage drive structure 12 performs the second stage drive, the baffle 18 is blocked by the fixed baffle 22, and the baffle 18 will pull the slide bar 17 to stop moving together, and the sliding plate 14 will continue to drive the guide sleeve 16 to slide, and the guide sleeve 16 will push the ring 21 to move, thereby driving the elastic member 19 on the elastic electrical connector 11 to bend and deform, so that the arch of the arched part on the elastic member 19 increases, and the elastic electrical connector 11 expands toward both sides, so that the electrical connection pieces 20 on both sides of the elastic member 19 move outward and fit tightly with the terminal 24 in the wiring hole of the circuit breaker 2 to achieve electrical connection. The arrangement of the electrical connection piece 20 is to strengthen the structural strength of the middle section on both sides of the elastic member 19, so that when the elastic member 19 arches and deforms, the part where the electrical connection piece 20 is installed does not deform, and the side of the electrical connection piece 20 that contacts the terminal 24 is a rough surface, so that the electrical connection piece 20 can contact the terminal 24 in the wiring hole of the circuit breaker 2 more reliably. The automatic wiring module 10 can realize automatic wiring of the circuit breaker 2, without the need for manual wiring of the circuit breaker 2, which can improve the detection efficiency. Through the two-stage driving structure 12, the elastic electrical connector 11 is first extended into the wiring hole of the circuit breaker 2, and then the elastic electrical connector 11 is stretched to achieve a tight connection with the terminal 24 in the wiring hole of the circuit breaker 2, thereby ensuring that the connection between the elastic electrical connectors 11 of the circuit breaker 2 is stable and reliable.

[0046] The sliding plate 14 is provided with three guide sleeves 16, and a position adjustment mechanism 25 for adjusting the position of the guide sleeve 16 is provided between the guide sleeve 16 and the sliding plate 14. The position adjustment mechanism 25 includes a strip groove 26 provided on the sliding plate 14, and the length direction of the strip groove 26 is perpendicular to the movement direction of the slide bar 17. The guide sleeve 16 is threaded with a fastening screw (not shown in the figure) that passes through the strip groove 26 and can fix the guide sleeve 16 on the sliding plate 14. A positioning strip 28 is fixedly provided on the sliding plate 14, and the positioning strip 28 is parallel to the strip groove 26. The side of the guide sleeve 16 facing the positioning groove is a plane and the plane is in contact with the positioning strip 28. The positioning strip 28 is used for the installation and positioning of the guide sleeve 16. The position adjustment mechanism 25 is provided to adjust the lateral position of the guide sleeve 16, that is, to adjust the lateral position of the elastic electrical connector 11 on different guide sleeves 16.

[0047] A spacing adjustment mechanism 29 is installed between the two groups of automatic wiring modules 10. The spacing adjustment mechanism 29 includes a base 30. The base 23 on the automatic wiring module 10 is slidably arranged on the base 30. The sliding directions of the bases 23 on the two groups of automatic wiring modules 10 are located on the same straight line. The base 23 is screwed with a fastening bolt 31 for fixing the base 23 on the base 30. The distance between the two groups of automatic wiring modules 10 can be adjusted by the spacing adjustment mechanism 29. Since the two groups of automatic wiring modules 10 are respectively located on both sides of the circuit breaker positioning and clamping module 3, the spacing between the automatic wiring module 10 and the circuit breaker positioning and clamping module 3 can also be adjusted, thereby realizing the adjustment of the spacing between the elastic electrical connector 11 and the circuit breaker 2 on the circuit breaker positioning and clamping module 3.

[0048] In summary, the arrangement of the position adjustment mechanism 25, the spacing adjustment mechanism 29, and the depth adjustment plate 8 on the circuit breaker positioning and clamping module 3 enables the arranged elastic electrical connector 11 to be aligned with the wiring hole on the circuit breaker 2 on the circuit breaker positioning and clamping module 3 when the present invention is used to test circuit breakers 2 of different specifications and sizes, so as to facilitate accurate wiring.

[0049] The present invention also provides a method for using a circuit breaker characteristic test device, using the circuit breaker characteristic test device, comprising the following steps:

[0050] S1: Turn the adjusting bolt on the circuit breaker positioning clamping module according to the specifications of the circuit breaker, and adjust the height of the depth adjustment plate so that the wiring hole on the circuit breaker and the elastic electrical connector are at the same height after the circuit breaker is installed on the circuit breaker positioning clamping module;

[0051] S2: Install the circuit breaker on the circuit breaker positioning clamping module;

[0052] S3: Adjust the position adjustment mechanism according to the specifications and dimensions of the circuit breaker, loosen the fastening screws, move the guide sleeve along the length direction of the strip groove until the elastic electrical connector is aligned with the corresponding wiring hole on the circuit breaker, and then tighten the fastening screws;

[0053] S4: Adjust the spacing adjustment mechanism, loosen the fastening bolts, slide the base, move the elastic electrical connector close to the corresponding wiring hole on the circuit breaker, and tighten the fastening bolts;

[0054] S5: Control the two-stage drive structure to start working. The two-stage drive structure performs the first stage of driving. The power component drives the sliding plate to slide toward the circuit breaker positioning and clamping module. At this time, the guide sleeve, the ring, the elastic electrical connector, the slide rod, and the baffle slide together with the sliding plate until the baffle fits with the fixed baffle and drives the elastic electrical connector to extend into the wiring hole of the circuit breaker. The two-stage drive structure performs the second stage of driving. The power component continues to drive the sliding plate to slide toward the circuit breaker positioning and clamping module. The baffle is blocked by the fixed baffle. The baffle pulls the slide rod to stop moving. The sliding plate continues to drive the guide sleeve to slide. The guide sleeve pushes the ring to move, thereby driving the elastic part on the elastic electrical connector to bend and deform, so that the arched part on the elastic part has an increased arch, so that the elastic electrical connector expands toward both sides, so that the electrical connection pieces on both sides of the elastic part move outward and fit tightly with the wiring posts in the wiring hole of the circuit breaker to achieve electrical connection.

[0055] S6: Control the detector to test the circuit breaker.

[0056] When testing circuit breakers of the same specifications and sizes, it is only necessary to adjust the height, position adjustment mechanism and spacing adjustment mechanism of the depth adjustment plate once, and no further adjustment is required. It is only necessary to load the circuit breakers of the same specifications into the circuit breaker positioning clamping module for automatic wiring, without manual wiring, which is very convenient.

The two-stage drive structure performs the second stage of driving, the power component continues to drive the sliding plate to slide toward the circuit breaker positioning clamping module, the baffle is blocked by the fixed baffle, the baffle pulls the slide bar to stop moving, the sliding plate continues to drive the guide sleeve to slide, the guide sleeve pushes the ring to move, thereby driving the elastic member on the elastic electrical connector to bend and deform, so that the arch of the arched part on the elastic member increases, so that the elastic electrical connector expands toward both sides, so that the electrical connection pieces on both sides of the elastic member move outward and fit tightly with the terminal in the circuit breaker wiring hole, so as to achieve electrical connection; S6: Control the detector to test the circuit breaker.
