DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0029] Example 1

[0030] like Figure 1-Figure 5 As shown, the present invention provides an intelligent testing device for a circuit breaker, comprising:

[0031] A detector 1, for testing a circuit breaker 2;

[0032] The circuit breaker clamping module 3 is used to clamp the circuit breaker 2. The circuit breaker 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. A guide inclined plate 7 for guiding the installation of the circuit breaker 2 is fixed on the clamping plate 5. Through the cooperation of the clamping plate 5 and the fixing member 4, it can be used to clamp circuit breakers 2 of different widths. The guide inclined plate 7 is arranged 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;

[0033] The automatic wiring module 10 is used to wire the circuit breaker 2 so that the circuit breaker 2 and the detector 1 are electrically connected. The automatic wiring module 10 is provided with two groups, which are respectively located on both sides of the circuit breaker 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 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 facing away from the circuit breaker clamping module 3. The sliding rod 17 moves toward the circuit breaker clamping module 3. The elastic electrical connector 11 is installed at one end, and 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, and the two sides of the elastic member 19 are in a curved shape that is arched on the side facing away from the sliding rod 17, and 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, and the side of the electrical connecting piece 20 facing away from the elastic member 19 is a rough structure, and a ring 21 is fixedly provided between the two sides of the opening of the elastic member 19, and the ring 21 is slidably sleeved on the sliding rod 17 and the ring 21 is in contact 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, and 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 .

[0034] like Figure 6As 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 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 7 As 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.

[0035] 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. A fastening screw (not shown in the figure) passing through the strip groove 26 and capable of fixing the guide sleeve 16 on the sliding plate 14 is screwed on the guide sleeve 16. 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. By means of the position adjustment mechanism 25, the number of guide sleeves 16 used and the lateral position of the guide sleeves 16 can be adjusted, that is, the lateral position of the elastic electrical connectors 11 on different guide sleeves 16 can be adjusted. When it is necessary to test a circuit breaker 2 with only one wiring hole on one side, only one guide sleeve 16 and the corresponding elastic electrical connector 11 are needed. When it is necessary to test a circuit breaker 2 with two or three wiring holes on one side, a corresponding number of guide sleeves 16 and the corresponding elastic electrical connector 11 are used.

[0036] When using the present invention to test a circuit breaker 2 of a new specification and size, it is necessary to first select and use a corresponding number of guide sleeves 16 and elastic electrical connectors 11 according to the number of wiring holes of the circuit breaker 2, and then clamp the circuit breaker 2 on the circuit breaker clamping module 3. During clamping, it can be judged by human eyes to make the symmetric plane of the circuit breaker 2 coincide with the symmetric plane of the circuit breaker clamping module 3 as much as possible. In this embodiment, the lengths of the protruding parts of the two ends of the circuit breaker 2 relative to the two sides of the circuit breaker clamping module 3 are close. Then, the power component 15 on the automatic wiring module 10 is controlled to work to realize automatic wiring of the circuit breaker 2. After wiring, the detector 1 can be used to test the performance parameters of the circuit breaker 2. The detector 1 used can select different types of testers according to needs, such as a circuit breaker intelligent characteristic tester.
