[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1, reference Figures 1 to 4, is the first embodiment of the present invention, which provides a wire clamp device for a test moving contact of a center-mounted high-voltage circuit breaker, comprising a test clamp 100, which is designed as a large clamp, so that it can conveniently clamp the test contact 501 of the circuit breaker 500, and at the same time, it can avoid the small clamp on the annular spring 502 outside the test contact 501, which will affect the spring over a long period of time, so the test contact 501 is clamped with a large clamp to protect the annular spring 502. In addition, if the annular spring 502 is broken by the small clamp, the test contact 501 will be scattered, which will cause a greater safety hazard;

[0044] A heat dissipation hole 101 is provided on the outer side of the test clamp 100. A plurality of heat dissipation holes 101 are provided on the outer side of the test clamp 100, so that the part in contact with the test clamp 100 during the test of the circuit breaker 500 can dissipate heat better, and thus the thermal performance of the circuit breaker 500 during the test will not be affected.

[0045] The experimental clamp 100 is provided with a receiving cavity 102, an output slot 103 is provided on the side of the experimental clamp 100, and a movable slot 104 communicating with the receiving cavity 102 is provided in the output slot 103 of the experimental clamp 100. The output component 200 includes an arc rod 201 slidably connected to the output slot 103, a lever 202 is fixedly connected to the end of the arc rod 201, and the lever 202 extends to a side away from the movable slot 104, a connecting rod 203 is fixedly connected to the position of the arc rod 201 corresponding to the movable slot 104, and an end of the connecting rod 203 located in the receiving cavity 102 is fixedly connected to an inclined block 204. An accommodating cavity 102 is provided inside the experimental clamp 100, and the accommodating cavity 102 cooperates with the heat dissipation hole 101 to increase the heat dissipation efficiency of the experimental contact 501 during the experiment. An output groove 103 is provided on the side of the experimental clamp 100, and the arc rod 201 is slidably connected in the output groove 103. The experimental clamp 100 is provided with a movable groove 104 at a position corresponding to the experimental contact 501 on the inner wall of the output groove 103, and the position of the arc rod 201 corresponding to the movable groove 104 is fixedly connected with a connecting rod 203, and the end of the connecting rod 203 passes through the movable groove 104, extends to the accommodating cavity 102, and is fixedly connected with a bevel block 204.

[0046] The experimental clamp 100 is provided with a sliding groove 105 penetrating therethrough. The experimental clamp 100 is located in the sliding groove 105 and is fixedly connected with an inclined block 106. The fastening component 300 includes a resistance component 301 movably installed in the experimental clamp 100, a support component 302 arranged at the inner side of the experimental clamp 100, and a connecting component 303 arranged between the resistance component 301 and the connecting component 303; the output component 200 slides along the output groove 103 to push the fastening component 300 to slide upward. Under the resistance of the sliding groove 105, the resistance component 301 and the connecting component 303 will drive the supporting component 302 to unfold. A sliding groove 105 is provided on the outer side of the clip 100 at the position corresponding to the experimental contact 501, and the sliding groove 105 is arranged in a through shape, so that the abutment component 301 can make the support component 302 unfold through the connection component 303 to support the inner wall of the experimental contact 501, thereby the experimental contact 501 will not be deformed in a local area due to the long-term clamping of the experimental contact 501 by the experimental clip 100. In addition, the experimental clip 100 cooperates with the support component 302. In this case, when a force is applied to the experimental contact 501 from both inside and outside at the same time, the stability between the experimental clip 100 and the experimental contact 501 can also be increased.

[0047] Example 2, reference Figure 1 to Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, the abutment assembly 301 includes an inclined block 301a, which is movably connected in the accommodating cavity 102 and the sliding groove 105, and the side of the inclined block 301a conflicts with the side of the inclined block 1 106; a conflict block 301b, which is fixedly connected to the side of the inclined block 301a, and the side of the inclined block 301a conflicts with the inclined block 204. Corresponding to the position of each pair of experimental contacts 501, an inclined block 301a is provided, and the inclined block 301a is movably connected in the accommodating cavity 102. The inclined block 301a is triangularly arranged, and one side of its inclined surface conflicts with the side of the inclined block 204. In this way, when the inclined block 204 follows the sliding of the connecting rod 203, the inclined block 204 is in a state of being pressed against the connecting rod 203. During the process, the inclined block 204 will resist the inclined block 301a and slide upward. The position of each pair of inclined blocks 301a corresponding to the inclined block 106 outside the inclined block 301a is fixedly connected with a resistance block 301b, and the inclined surfaces between each pair of resistance blocks 301b are symmetrically arranged. At the same time, the inclined blocks 106 in each pair of sliding grooves 105 are also symmetrically arranged, and the inclined surface of the resistance block 301b resists the inclined block 106. In this way, when the resistance block 301b follows the movement of the inclined block 204, it will be resisted by the inclined block 106. At this time, the resistance block 301b will slide in the direction of the inclined block 204. At this time, each pair of resistance blocks 301b can slide to both sides in the sliding groove 105.

[0048] Furthermore, the support assembly 302 further includes a first support plate 302a and a second support plate 302b, the end of the first support plate 302a is arranged in a groove shape, the second support plate 302b is arranged in a convex shape at the end of the first support plate 302a, and the outer sides of the first support plate 302a and the second support plate 302b are both provided with a slide groove 302c; the connecting assembly 303 includes a connecting rod 303a arranged in the slide groove 302c, the end of the connecting rod 303a passes through the sliding groove 105 and is connected to the resistance block 301b; the output component 200 slides to push the resistance assembly 30 When the first support plate 302a and the second support plate 302b are sliding, the contact block 301b drives the connecting rod 303a to slide in the sliding groove 302c; when the inclined block 301a is located at the end of the sliding groove 105, the connecting rod 303a will slide to the end of the sliding groove 302c, and the first support plate 302a and the second support plate 302b will be unfolded. The connecting assembly 303 includes a shaft rod 303b, which is arranged between the first support plate 302a and the second support plate 302b; a coil spring 303c, which is sleeved on the outside of the shaft rod 303b; the coil spring 303c can apply relative force to the first support plate 302a and the second support plate 302b. For the rotational force, the first support plate 302a and the second support plate 302b are arranged at the inner wall position of the test clamp 100 corresponding to each pair of test contacts 501, the end of the first support plate 302a is arranged in a groove shape, and the end of the second support plate 302b is arranged in a convex shape, and the convexity of the end of the second support plate 302b is located in the groove of the first support plate 302a, and the convexity is rotatably connected to the shaft rod 303b on one side, and the shaft rod 303b is fixedly connected on the other side, and the outer side of the shaft rod 303b is sleeved with a coil spring 303c, and the convexity is fixed to the shaft rod 303b on the other side. The coil spring 303c outside the rotation connection shaft 303b is connected to the groove-shaped inner wall of the first support plate 302a, and the coil spring 303c connected to the outer sleeve of the protruding fixed connection shaft 303b is connected to the protrusion of the second support plate 302b, so that the first support plate 302a and the second support plate 302b can achieve a relatively rotating and combined state in the absence of external force. In this way, when the test clamp 100 clamps the test contact 501, the first support plate 302a and the second support plate 302b can enter the inner wall position of the test contact 501 from the gap between them in the combined state;

[0049] The outer walls of the first support plate 302a and the second support are both provided with a sliding groove 302c, and the sliding groove 302c is movably connected with a connecting rod 303a, and the ends of the connecting rod 303a pass through the sliding groove 105 and are connected to the abutment block 301b. Therefore, during the sliding process of the abutment block 301b, the first support plate 302a and the second support will be driven to approach the inner wall of the experimental contact 501, and when the abutment block 301b slides to both sides, the connecting rod 303a will also slide to both sides in the sliding groove 302c. At this time, the first support plate 302a and the second support The plate 302b will unfold under the action of the connecting rod 303a, and after the unfolding, it will apply an outward force to the experimental contact 501. At this time, the clamping force of the experimental clamp 100 and the outward force of the first support plate 302a and the second support plate 302b are coordinated, so as to avoid the experimental contact 501 from being deformed in a local area due to the experimental clamp 100 clamping the experimental contact 501 for a long time. In addition, when the internal and external forces are applied to the experimental contact 501 at the same time, the stability between the experimental clamp 100 and the experimental contact 501 can also be increased.

[0050] The rest of the structure is the same as that of Example 1.

[0051] Example 3, reference Figure 1 to Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment, it also includes a locking component 400; it includes a sliding component 401 arranged outside the output component 200, and a limiting component 402 arranged outside the test clamp 100. During the sliding process of the above-mentioned output component 200, the sliding component 401 will be driven to resist the limit and rise. After moving to a certain distance, the limiting component 402 will fall to limit the sliding component 401, thereby locking the above-mentioned arc rod 201.

[0052] Specifically, the sliding assembly 401 includes an L-shaped locking rod 401a disposed at the end of the lever 202, and an arc spring 401c is disposed between the inner wall of the output slot 103 and the lever 202; the arc spring 401c can apply a pulling force to the output component 200 away from the fastening component 300, and the end of the lever 202 is fixedly connected to the L-shaped locking rod 401a, and the crossbar portion of the L-shaped locking rod 401a is disposed above the outside of the experimental clamp 100, and the crossbar portion of the L-shaped locking rod 401a is disposed in the shape of an arc surface 401b, so that During the movement of the L-shaped locking rod 401a, the arc surface 401b can easily limit the component 402 from being pushed open. In addition, an arc spring 401c is provided on the inner wall of the lever 202 and the output slot 103. In this way, during the sliding movement of the arc rod 201 and the lever 202, the arc spring 401c will apply a pulling force to the lever 202. At this time, after the restriction on the L-shaped locking rod 401a is released, the arc spring 401c will drive the arc rod 201, the lever 202 and the L-shaped locking rod 401a to reset.

[0053] Furthermore, the limiting assembly 402 includes a frame 402a disposed outside the test clamp 100, and the frame 402a is provided with an opening 402b at the position of the L-shaped locking rod 401a; the cross bar portion of the L-shaped locking rod 401a can enter the interior of the frame 402a through the opening 402b, and the cross bar portion of the L-shaped locking rod 401a is provided with an arc surface 401b at the position corresponding to the frame 402a; the limiting assembly 402 also includes an opening The frame 402a has a power storage groove 402c at the opening 402b, in which a limiting rod 402d is slidably connected, and an elastic member 402e is provided between the limiting rod 402d and the power storage groove 402c; the arcuate surface 401b of the L-shaped locking rod 401a can resist the limiting rod 402d to squeeze the elastic member 402e to store power, and when the L-shaped locking rod 401a enters the frame 402a, the L-shaped locking rod 401a has no The limiting assembly 402 further includes a lifting rod 402f disposed at the end of the limiting rod 402d, the lifting rod 402f is slidably connected to the force storage groove 402c of the frame 402a, and the lifting rod 402f is disposed in the middle of the elastic member 402e. Therefore, when the L-shaped locking rod 401a moves toward the frame 402a, the arc surface 401b of the cross bar portion of the L-shaped locking rod 401a will conflict with the limiting rod 402d and the lifting rod. The rod 402f slides upward, and at the same time, the resistance rod will squeeze the elastic member 402e, so that the elastic member 402e accumulates force in the force storage groove 402c. When the cross bar part of the L-shaped locking rod 401a enters the frame 402a, the elastic member 402e will push the limiting rod 402d and the lifting rod 402f to reset. At the same time, the limiting rod 402d will limit the L-shaped locking rod 401a, and the locking of the fastening component 300 is completed.
