[0077] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the high-speed mechanical switch of the present invention. The high-speed mechanical switch of the present invention is not limited to the descriptions in the following embodiments.

[0078] The high-speed mechanical switch of the present invention is preferably applied to hybrid solid-state circuit breakers.

[0079] The height direction, length direction, and width direction of the high-speed mechanical switch of the present invention are directions d1, d2, and d3, respectively, and directions d1, d2, and d3 are perpendicular to each other.

[0080] The high-speed mechanical switch of the present invention includes a housing 100, a stationary contact group 200, and a moving contact mechanism 500, a closing coil 300, a closing coil 400, and a steady-state mechanism, all disposed within the housing 100.

[0081] The stationary contact assembly 200 is fixedly mounted on the housing 100. At least the portion with stationary contacts is located inside the housing 100, while the remaining portion can be located inside the housing 100 or protrude outside the housing 100 as needed.

[0082] The moving contact mechanism 500 is configured to reciprocate along direction d1 and switch between a closed position and an open position to close and open with the stationary contact group 200 respectively; that is, the moving contact mechanism 500 has a closed position and an open position, and switches between the closed position and the open position by reciprocating along direction d1 to close and open with the stationary contact group 200.

[0083] The closing coil 300 is used to drive the moving contact mechanism 500 to move to the closed position. That is, when the moving contact mechanism 500 is in the open position, the closing coil 300 can drive the moving contact mechanism 500 to move from the open position to the closed position.

[0084] The tripping coil 400 is used to drive the moving contact mechanism 500 to move to the open position. That is, when the moving contact mechanism 500 is in the closed position, the tripping coil 400 can drive the moving contact mechanism 500 to move from the closed position to the open position.

[0085] The steady-state mechanism has three operating states that switch sequentially as the moving contact mechanism 500 moves. These states are, in turn, a first steady state for holding the moving contact mechanism 500 in the closed position, a critical state, and a second steady state for holding the moving contact mechanism 500 in the open position. That is, the steady-state mechanism has three operating states: a first steady state, a critical state, and a second steady state. These states can be switched sequentially in the order of first steady state → critical state → second steady state (when the moving contact mechanism 500 moves from the closed position to the open position, the steady-state mechanism...). This switching sequence switches the working state (either the second steady state → critical state → first steady state). When the moving contact mechanism 500 moves from the open position to the closed position, the steady-state mechanism switches the working state in this sequence. The working state of the steady-state mechanism changes as the moving contact mechanism 500 moves. In the first steady state, the steady-state mechanism is used to keep the moving contact mechanism 500 in the closed position. In the second steady state, the steady-state mechanism is used to keep the moving contact mechanism 500 in the open position. The critical state is a temporary unstable state, which is a transitional working state that the steady-state mechanism goes through when switching between the first and second steady states.

[0086] like Figures 1-13 The figure shown is a first embodiment of the high-speed mechanical switch of the present invention.

[0087] like Figures 1-2 As shown, the shell 100 includes a first half-shell 101 and a second half-shell 130 that are spliced ​​together to form the shell 100.

[0088] Specifically, the first half-shell 101 and the second half-shell 130 are joined together along direction d1.

[0089] like Figures 1-2 As shown, the stationary contact group 200 includes two stationary contacts, namely a first stationary contact 201 and a second stationary contact 202, one for connecting the wire on the power supply side and the other for connecting the wire on the load side; the moving contact mechanism 500 includes a moving contact 510, which moves reciprocally along direction d1 under the drive of the moving contact mechanism 500 to close and open synchronously with the two stationary contacts.

[0090] Specifically, the first stationary contact 201 and the second stationary contact 202 are arranged side by side at intervals along direction d2. One end of the first stationary contact 201 and the second stationary contact 202 is provided with a stationary contact point and this end is located inside the housing 100, while the other end serves as a wiring terminal and this end protrudes outside the housing 100. The moving contact 510 includes a moving contact bridge 501, a first moving contact 502 and a second moving contact 503. The first moving contact 502 and the second moving contact 503 are respectively arranged at both ends of the moving contact bridge 501 in direction d2 and respectively cooperate with the first stationary contact 201 and the second stationary contact 202.

[0091] like Figures 3-6 As shown, the moving contact mechanism 500 includes a moving contact 510, an insulating base 520, an overtravel component 540, and a repulsion disk 550; the overtravel component 540 includes a moving contact spring 541, which cooperates with the moving contact 510 and the insulating base 520 respectively; the moving contact 510 and the repulsion disk 550 are located at both ends of the moving contact mechanism 500 in direction d1; the opening coil 400, the moving contact 510, the repulsion disk 550, and the closing coil 300 are arranged sequentially along direction d1; the opening coil 400 drives the moving contact mechanism 510 to move towards the open position along direction d1 through the moving contact 510; the closing coil 300 drives the moving contact mechanism 510 to move towards the closed position along direction d1 through the repulsion disk 550. Furthermore, the insulating base 520 includes an insulating base main board 521; the moving contact 510, the insulating base main board 521, and the repulsion disk 550 are arranged sequentially along direction d1; the moving contact spring 541 is disposed between the moving contact 510 and the insulating base main board 521, and the two ends of the moving contact spring 541 cooperate with the moving contact 510 and the insulating base main board 521 respectively, for providing the moving contact mechanism 500 with a force to press the stationary contact group 200 when the moving contact mechanism 500 is in the closed position, and the moving contact spring 541 acts on the moving contact 510 to make it have a tendency to move away from the insulating base main board 521 along direction d1. Furthermore, the insulating base main board 521 is fixed together with the repulsion disk 550 and always remains relatively stationary; the moving contact 510 is moved relative to the insulating base 520 along direction d1; that is, the moving contact 510 contacts the stationary contact group 200 before the moving contact mechanism 500 reaches the closed position. During the process from when the moving contact 510 contacts the stationary contact group 200 until the moving contact mechanism 500 reaches the closed position, the moving contact 510 will move relative to the insulating base 520 along direction d1, thereby storing energy in the moving contact spring 541. The force exerted by the moving contact spring 541 on the moving contact 510 makes the moving contact 510 reliably close with the stationary contact group 200.

[0092] like Figure 3 , 4As shown, the overtravel assembly 540 also includes a guide connecting rod 542. One end of the guide connecting rod 542 cooperates with the moving contact 510, and the other end passes through the insulating base main board 521 and cooperates with the repulsion disk 550, connecting the moving contact 510, the insulating base 520 and the repulsion disk 550 together. The moving contact spring 542 is sleeved on the guide connecting rod 542, and its two ends cooperate with the moving contact 510 and the insulating base main board 521 respectively. Furthermore, the guide connecting rod 542 fixes the insulating base main board 521 and the repulsion disk 55 together. The guide connecting rod 542, the insulating base main board 521, and the repulsion disk 550 always remain relatively stationary. That is, during the operation of the moving contact mechanism 500, the guide connecting rod 542, the insulating base main board 521, and the repulsion disk 550 always move synchronously and do not move relative to each other. One end of the guide connecting rod 542 is slidably inserted into the moving contact 510, that is, the moving contact 510 is slidably set relative to the guide connecting rod 542. The moving contact mechanism 500, with its guide connecting rod 542, can not only connect the moving contact 510, the insulating base 520, and the repulsion disk 550, but also limit the movement of the moving contact spring 541, simplifying the structure of the moving contact mechanism 500 and ensuring its structural stability.

[0093] Specifically, the guide connecting rod 542 includes a cap 543 and a rod body 544. The outer diameter of the cap 543 is larger than the outer diameter of the rod body 544. One end of the rod body 544 is connected to the cap 543, and the other end passes through the moving contact 510 and the insulating base main board 521 in sequence to be fixedly connected to the repulsion disk 550. The moving contact spring 541 is sleeved on the rod body 544, and the cap 543 is in a limiting fit with the moving contact 510. Further, the moving contact bridge 501 of the moving contact 510 is provided with a moving contact hole 504 through which the rod body 544 of the guide connecting rod 542 passes. The moving contact hole 504 includes an upper section 505 and a lower section 506 of the moving contact hole arranged sequentially and connected along the direction d1. The diameter of the upper section 505 is larger than the diameter of the lower section 506. A first step 507 is formed at the connection between the upper section 505 and the lower section 506 of the moving contact hole. 543 is limited and engaged with the first step 507; the diameter of the upper section 505 of the moving contact hole is adapted to the outer diameter of the cap 543 and allows the cap 543 to slide within it; the main board 521 of the insulating base is provided with an insulating base connecting hole 536 through which the rod body 544 of the guide connecting rod 542 passes, the insulating base connecting hole 536 includes an upper section 566 and a lower section 567 of the insulating base connecting hole arranged sequentially and connected along the direction d1, the upper section 566 of the insulating base connecting hole 566... The aperture of 66 is larger than the aperture of the lower section 567 of the insulating seat connection hole, and a second step 568 is formed at the connection between the upper section 566 and the lower section 567 of the insulating seat connection hole; the repulsion disk 550 is provided with a repulsion disk connection hole 552; the rod body 544 includes an upper section 545 and a lower section 546 connected sequentially along direction d1, and the cap 543, the upper section 545, and the lower section 546 are connected sequentially; the upper section 545 is respectively connected to... The lower section 506 of the moving contact hole and the upper section 566 of the insulating seat connection hole are adapted to each other, and the outer diameter of the lower section 546 of the rod body is adapted to the lower section 567 of the insulating seat connection hole. The end of the upper section 545 of the rod body connected to the lower section 546 of the rod body is limited and fitted with the second step 568. After the lower section 546 of the rod body passes through the lower section 567 of the insulating seat connection hole, it is inserted into the repulsion disk connection hole 552 and threadedly connected thereto, thereby fixing the insulating seat 520 and the repulsion disk 550 together. Furthermore, a connecting washer is provided between the upper section 545 of the rod body and the second step 568.

[0094] Specifically, the insulating base 520 further includes a spring limiting part 523 disposed on the insulating base main board 521. One end of the moving contact spring 541 is limited and engaged with the spring limiting part 532, and the other end is engaged with the moving contact 510. The spring limiting part 523 protrudes towards the side where the moving contact 510 is located. The spring limiting part 523 includes a coaxial inner wall 535 and an outer wall 533 arranged sequentially from the inside to the outside, forming an annular spring limiting hole 534 between the inner wall 535 and the outer wall 533. One end of the moving contact spring 541 is inserted into the spring limiting hole 534 and sleeved on the inner wall 535. The guide connecting rod 542 passes through the middle of the inner wall 535. Further, the inner wall 535 is provided with an insulating base connecting hole 536 coaxially disposed therewith. It should be noted that the spring limiting part 523 may also only have an inner wall 535 without an outer wall 533, that is, the moving contact spring 541 is sleeved on the outside of the inner wall 535 of the limiting part. The moving contact mechanism 500 has four sets of overtravel components 540. Correspondingly, the insulating seat 520 has four sets of spring limiting parts 523 and four sets of insulating seat connecting holes 536, the moving contact 510 has four sets of moving contact holes 504, and the repulsion disk 550 has four sets of repulsion disk connecting holes 552. The projection direction of the moving contact mechanism 500 is the orthogonal projection of direction d1. The four sets of spring limiting parts 523 are located at the four vertices of a square, the four sets of moving contact holes 504 are located at the four vertices of a square, and the four sets of repulsion disk connecting holes 552 are located at the four vertices of a positive direction.

[0095] As another embodiment of the spring limiting part 523, the spring limiting part 523 is an annular groove provided on the insulating base main board 521, which is coaxially arranged with the insulating base connecting hole 536.

[0096] like Figures 3-5As shown, the insulating base 520 also includes insulating base connecting arms 522. Two sets of insulating base connecting arms 522 are arranged opposite each other along direction d2 and are respectively connected to both ends of the insulating base main board 521. The two sets of insulating base connecting arms 522 respectively limit the two ends of the moving contact 510, and are used to pre-assemble the moving contact 510, the insulating base 520, and the moving contact spring 541 together and limit the maximum distance between the moving contact 510 and the insulating base main board 521. The moving contact 510 has the degree of freedom to move towards the insulating base main board 521 along direction d1, that is, the moving contact 510 can move towards the insulating base main board 521 along direction d1. The insulating base connecting arms 522 realize the pre-assembly of the moving contact 510, the insulating base 520 and the moving contact spring 541, reduce the assembly difficulty of the moving contact mechanism 500 and improve the assembly efficiency. The moving contact 510 is also slidably engaged with two sets of insulating base connecting arms 522 at both ends, which improves the stability and reliability of the moving contact 510 when it moves relative to the insulating base 520 in the direction d1.

[0097] Specifically, the moving contact spring 541 causes the moving contact 510 to be in a limiting engagement with the insulating base connecting arm 522. When the moving contact spring 541 is in a tensioned state, the moving contact 510 has a tendency to move away from the insulating base main board 521 along the direction d1. The limiting engagement between the insulating base connecting arm 522 and the moving contact 510 limits the maximum distance between the moving contact 510 and the insulating base main board 521. When the moving contact 510 is subjected to external force, it can move towards the insulating base main board 521 along the direction d1. Furthermore, the insulating base connecting arm 522 is provided with a connecting claw 532, and the connecting claw 532 is provided with a hook 538; the moving contact 510 is provided with a pre-installed step 508; under the action of the moving contact spring 541, the moving contact 510 causes the pre-installed step 508 to abut and limit the connecting claw 532 along direction d1, thereby pre-installing the moving contact 510, the insulating base 520 and the moving contact spring 541 together and limiting the maximum distance between the moving contact 510 and the insulating base main board 521. Furthermore, the moving contact 510 is provided with four pre-installed steps 508, which are located at the four vertices of a rectangle on the orthogonal projection of the moving contact mechanism 500 in direction d1; each insulating base connecting arm 522 is provided with two sets of connecting claws 532, which are arranged side by side and spaced apart along direction d3; the pre-installed steps 508 and the connecting claws 532 are matched one-to-one. Furthermore, each end of the moving contact 510 in direction d2 is a square-headed structure, and the two pre-installed steps 508 at each end are located at the two corners of that end. Furthermore, the moving contact 510 also has a moving contact guide groove 509 that corresponds to and cooperates with the pre-installed steps 508. The pre-installed steps 508 are formed at one end of the moving contact guide groove 509 in direction d1; the hook 538 is slidably disposed within the corresponding moving contact guide groove 509 (the hook 538 preferably engages with the side wall of the corresponding moving contact guide groove 509 to limit its movement, so that the moving contact 510 can only move along direction d1). Furthermore, the moving contact 510 is also provided with a guide slope 511, which corresponds to and cooperates with the pre-installed step 507. The guide slope 511 is configured to cooperate with the hook 538 before the pre-installed step 508 when the moving contact 510 is pre-installed with the insulating base 520, so as to guide the hook 538 into the moving contact guide groove 509 and cooperate with the pre-installed step 508. The moving contact guide groove 509, the pre-installed step 508 and the guide slope 511 are arranged sequentially along the direction d1. Furthermore, the insulating base connecting arm 522 also includes a connecting arm main board 530. One end of the connecting arm main board 530 is connected to the insulating base main board 521, and the other end is provided with a connecting claw 532. The connecting claw 532 also includes a connecting rib 539. In the direction d3, the width of the connecting rib 539 is smaller than the width of the connecting arm main board 530. One end of the connecting rib 539 is connected to the connecting arm main board 530, and the other end is provided with a hook 538, thereby improving the deformation capability of the connecting claw 532 and facilitating the assembly of the connecting claw 532 and the moving contact 510.

[0098] It should be noted that the pre-installed step 508 and connecting claw 532 can also be arranged in other ways. For example, the moving contact 510 has a pre-installed step 508 at each end in the direction d2. The pre-installed step 508 has a certain width and is located in the middle of the corresponding end of the moving contact 510. Each of the two sets of insulating seat connecting arms 522 is provided with a hook 538 with a certain width. The pre-installed step 508 and the hook 538 are matched one-to-one so that the moving contact 510 and the insulating seat 520 can basically remain relatively stationary in the pre-assembled state. Those skilled in the art can make various modifications according to conventional technical means, which will not be listed here, and all should fall within the protection scope of this application.

[0099] like Figure 2 As shown, the insulating seat connecting arm 522 also slides with the inner side of the housing 100, improving the stability and reliability of the moving contact mechanism 500. The two sets of insulating seat connecting arms 522 slide with the first left wall 119 and the first right wall 120 of the first half-shell 101, respectively.

[0100] Specifically, the connecting arm main board 530 also provides a connecting arm sliding rib 531. The connecting arm sliding rib 531 is an elongated structure extending along direction d1, reducing the contact area between the insulating seat connecting arm 522 and the housing 100, thereby reducing the sliding resistance between the moving contact mechanism 500 and the housing 100. Furthermore, the connecting arm main board 530 provides at least two sets of connecting arm sliding ribs 531, with each set of connecting arm sliding ribs 531 arranged side-by-side at intervals along direction d3. Furthermore, the cross-section of the connecting arm sliding rib 531 perpendicular to direction d1 is a semi-circular protruding structure.

[0101] like Figure 3 , 4 As shown, the moving contact 510 also includes two sets of moving contact guide protrusions. The two sets of moving contact guide protrusions are respectively arranged at both ends of the moving contact 510 in the direction d3. The moving contact guide protrusions are used to slide and insert into the fourth groove 112 of the housing 100, which improves the operation stability and reliability of the moving contact mechanism 500.

[0102] like Figures 3-5 As shown, the insulating base main board 521 also includes two sets of insulating base guide protrusions. The two sets of insulating base guide protrusions are respectively disposed at both ends of the insulating base main board 521 in the direction d3. The free ends of the insulating base guide protrusions are used to slide into the housing third groove 107 of the housing 100, which improves the operation stability and reliability of the moving contact mechanism 500.

[0103] like Figure 3 , 4As shown in Figure 6, the repulsion disk 550 also includes a repulsion disk guide protrusion 554, which is used to slide and insert into the third groove 107 of the housing 100, thereby improving the stability and reliability of the moving contact mechanism 500.

[0104] Specifically, the moving contact 510 has an overall cross-shaped structure; the moving contact guide protrusion includes a moving contact protrusion side and a moving contact guide side 512. The moving contact guide side 512 is disposed on the free end of the moving contact guide protrusion. The two protrusion sides are arranged relatively apart along direction d2 and are respectively bent and connected to the two ends of the moving contact guide side 512. The moving contact guide side 512 is an arc-shaped surface, and the center line of the arc-shaped surface is parallel to direction d1. The moving contact protrusion side and the moving contact guide side 512 are both slidably engaged with the side wall of the fourth groove 112 of the housing. The insulating base main board 521 has an overall cross-shaped structure; the insulating base guide protrusion includes an insulating base protrusion side and an insulating base guide side 547. The insulating base guide side 547 is disposed on the free end of the insulating base guide protrusion. The two insulating base protrusion sides are arranged at intervals along direction d2 and are respectively bent and connected to the two ends of the insulating base guide side 547. The insulating base guide side 547 is an arc-shaped side, and the center line of the arc-shaped side is parallel to direction d1. Both the insulating base protrusion side and the insulating base guide side 547 are slidably engaged with the side wall of the third groove 107 of the housing. The repulsion disk 550 has an overall cross-shaped structure; the repulsion disk guide protrusion 554 includes a repulsion disk protrusion side and a repulsion disk guide side. The repulsion disk guide side is disposed on the free end of the repulsion disk guide protrusion 554. The two repulsion disk protrusion sides are arranged at intervals along direction d2 and are respectively bent and connected to the two ends of the repulsion disk guide side. The repulsion disk guide side is an arc-shaped surface, and the center line of the arc-shaped surface is parallel to direction d1. Both the repulsion disk protrusion side and the repulsion disk guide side are slidably engaged with the side wall of the third groove 107 of the housing.

[0105] like Figures 3-5 As shown in Figures 8-11, the insulating base 520 also includes an insulating base guide portion 524 disposed on the insulating base main board 521. The insulating base guide portion 524 and the moving contact 510 are respectively located on both sides of the insulating base main board 521 in the direction d1. The insulating base guide portion 524 is used to slide into the housing guide hole 104 disposed on the first bottom wall 108 of the housing 100, thereby improving the reliability and stability of the movement of the moving contact mechanism 500.

[0106] Specifically, the insulating base 520 includes two sets of insulating base guide portions 524, which are arranged side by side and spaced apart along direction d2. Further, the insulating base guide portion 524 has a cylindrical structure with a built-in buffer spring. The two ends of the buffer spring cooperate with the insulating base 520 and the housing 100 (specifically, the first bottom wall 108 of the first half-shell 101), respectively. This buffers the moving contact mechanism 500 during opening and reduces the force exerted by the closing coil on the moving contact mechanism 500 (specifically, the repulsion disk 550) during closing. This reduces the number of turns in the closing coil 300, thus reducing its size and volume, or it reduces the starting current required by the closing coil 300.

[0107] like Figures 4-6 As shown, the insulating base main board 521 also includes a positioning post 525 disposed on the insulating base main board 521. The moving contact 510 and the positioning post 525 are respectively located on both sides of the insulating base main board 521 in the direction d1. The repulsion disk 550 also includes a repulsion disk positioning hole 553. The positioning post 521 and the repulsion disk positioning hole 553 are inserted and matched to pre-assemble the repulsion disk 550 and the insulating base 520 together, so that the repulsion disk 550 and the insulating base 520 are assembled together in the correct manner, thereby improving assembly efficiency.

[0108] Specifically, the insulating base main board 521 is provided with two sets of positioning posts 525, which are arranged side by side and spaced apart along direction d3; the repulsion disk 550 is provided with two sets of repulsion disk positioning holes 553, which are arranged side by side and spaced apart along direction d3.

[0109] like Figures 4-6 As shown in Figure 11, the insulating base 520 further includes an insulating base guide hole 537 disposed on the insulating base main board 521; the repulsion disk 550 further includes a repulsion disk guide hole 551 disposed corresponding to the insulating base guide hole 537; the insulating base guide hole 537 and the repulsion disk guide hole 551 are used for the housing guide post 106 of the housing 100 to be slidably inserted therein, that is, the insulating base main board 521 and the repulsion disk 550 are slidably sleeved on the housing guide post 106 through the insulating base guide hole 537 and the repulsion disk guide hole 551 respectively, which improves the movement stability and reliability of the moving contact mechanism 500.

[0110] Specifically, the insulating base main board 521 has only one insulating base guide hole 537; two sets of insulating base guide parts 524 are located on both sides of the insulating base guide hole 537 in direction d2; two sets of positioning posts 525 are located on both sides of the insulating base guide hole 537 in direction d3; and four sets of spring limiting parts 523 are arranged around the insulating base guide hole 537. The repulsion disk 550 has only one repulsion disk guide hole 551; four sets of repulsion disk connecting holes 552 are arranged around the repulsion disk guide hole 551; the insulating base 520 has a centrally symmetrical structure with the axis of the insulating base guide hole 537 as the axis of symmetry. Two sets of repulsion disk positioning holes 553 are located on both sides of the repulsion disk guide hole 551 in direction d3, and the two sets of repulsion disk positioning holes 553 are respectively arranged on the two sets of repulsion disk guide protrusions 554; the repulsion disk 550 has a centrally symmetrical structure with the axis of the repulsion disk guide hole 551 as the axis of symmetry. The housing 100 has only one housing guide post 106. The moving contact 510 is preferably a centrally symmetrical structure with the axis of the insulating seat guide hole 537 and the axis of the repulsion disk guide hole 551 as the axis of symmetry. The above design improves the balance of the moving contact mechanism 500 during operation.

[0111] like Figure 2 , 12 As shown, the high-speed mechanical switch of the first embodiment has four sets of steady-state mechanisms. On the orthogonal projection of the high-speed mechanical switch along direction d1, the four sets of steady-state mechanisms are located at the four vertices of a rectangle. The moving contact mechanism 500 has two sets of steady-state mechanisms on each side of direction d3, with two sets of steady-state mechanisms on the same side of the moving contact mechanism 500 arranged side-by-side and spaced apart along direction d2. Two sets of steady-state mechanisms are arranged opposite each other along direction d3, and the other two sets of steady-state mechanisms are also arranged opposite each other along direction d3. It should be noted that the number of steady-state mechanisms can be adjusted according to actual needs. The opening coil 400, the moving contact mechanism 500, and the closing coil 300 are arranged sequentially along direction d1, and the positioning component 600 is arranged side-by-side with the moving contact mechanism 500 along direction d3. This layout reduces the size of the high-speed mechanical switch.

[0112] In other embodiments, the steady-state mechanism can also be respectively arranged on both sides of the moving contact mechanism 500 in the direction d2, that is, the two sets of positioning components 600 are respectively arranged on both sides of the moving contact mechanism 500 in the direction d2, and each of the two sets of insulating seat connecting arms 522 of the insulating seat 520 is provided with a positioning part 526, which cooperates with the two sets of positioning components 600 respectively.

[0113] like Figures 2-5As shown in Figures 7-10, the steady-state mechanism includes a positioning component 600 and a positioning part 526, one of which moves synchronously with the moving contact mechanism 500 and the other is fixedly disposed; that is, the positioning component 600 is synchronously moved with the moving contact mechanism 500 and the positioning part 526 is fixedly disposed, or the positioning part 526 is synchronously moved with the moving contact mechanism 500 and the other is fixedly disposed. In the high-speed mechanical switch of the first embodiment, the positioning component 600 is fixedly disposed, and the positioning part 526 is synchronously moved with the moving contact mechanism 500.

[0114] like Figures 7-10 As shown, the positioning component 600 includes a linearly sliding positioning member 620 and a locking spring cooperating with the positioning member 620. The sliding direction of the positioning member 620 is perpendicular to direction d1. The locking spring stores and releases energy during the sliding process of the positioning member 620. The positioning member 620 and the positioning part 526 are oppositely engaged along direction d3. In this embodiment, the sliding direction of the positioning member 620 is direction d3. The locking member is configured to store energy to its maximum value when the steady-state mechanism is in the critical state, that is, the locking spring stores energy to its maximum value when the steady-state mechanism is in the critical state.

[0115] The positioning element 620 is configured as follows:

[0116] When the steady-state mechanism switches from the first steady state or the second steady state to the critical state, it is driven by the positioning part 526 to slide, so as to avoid the positioning part 526 and store energy in the locking spring; and,

[0117] When the steady-state mechanism switches from the critical state to the first steady state or the second steady state, it is driven by the released locking spring to slide, so as to establish a limiting engagement with the positioning part 526 and limit the moving contact mechanism 500 to the closed position or the open position.

[0118] That is, when the steady-state mechanism switches from the first steady state or the second steady state to the critical state, the instantaneous force of the opening coil 400 or the closing coil 300 on the moving contact mechanism 500 causes the positioning part 526 to drive the positioning member 620 to slide. The positioning member 620 avoids the positioning part 526 due to the force of the positioning part 526 and at the same time, the locking spring stores energy. When the steady-state mechanism reaches the critical state, the locking spring stores energy to its maximum value. When the steady-state mechanism switches from the critical state to the first steady state or the second steady state, the locking spring releases energy and drives the positioning member 620 to slide, thereby establishing a limiting cooperation with the positioning part 526 to limit the moving contact mechanism 500 to the closed position or the open position.

[0119] like Figures 7-10 As shown, the positioning member 620 is also rotatably configured, that is, the positioning member 620 is linearly sliding and simultaneously rotating; the sliding direction, the rotation axis direction, and direction d1 of the positioning member 620 are perpendicular to each other. In this embodiment, the rotation axis direction of the positioning member 620 is direction d2.

[0120] The positioning element 620 is further configured to rotate under the drive of the positioning part 526 when the steady-state mechanism switches its operating state; that is, when the steady-state mechanism switches its operating state—from the first steady state or the second steady state to the critical state / from the critical state to the first steady state or the second steady state—the positioning part 526 drives the positioning element 620 to rotate. This rotational configuration of the positioning element 620 reduces the contact resistance between the positioning element 620 and the positioning part 526, thereby allowing the steady-state mechanism to switch operating states more smoothly, and also reduces damage to the positioning element 620 and the positioning part 526 during operation, which helps to extend the service life of the steady-state mechanism.

[0121] Specifically, in this embodiment, the positioning element 620 is implemented by a roller.

[0122] As another embodiment of the positioning element 620, the positioning element 620 can also be implemented by ball bearings, which are rotatably disposed on the guide element 630.

[0123] Specifically, such as Figures 8-10 As shown, when the steady-state mechanism is in the first steady state or the second steady state, it simultaneously keeps the moving contact mechanism 500 in the closed position or the open position. When the instantaneous driving force of the opening coil 400 or closing coil 300 drives the moving contact mechanism 500 to move to the open or closed position, the moving contact mechanism 500 simultaneously drives the positioning part 526 to move synchronously, overcoming the limiting cooperation between the positioning part 526 and the positioning member 620. The positioning part 526 presses against the positioning member 620, causing it to slide along direction d3 and rotate simultaneously. The positioning member 620 stores energy in the locking spring. When the steady-state mechanism switches to the critical state, the locking spring stores energy to its maximum value. Then, the moving contact mechanism 500 continues to move by relying on inertia, causing the steady-state mechanism to pass through the critical state. The locking spring begins to release energy and drives the positioning member 620 to slide along direction d3. At the same time, the positioning member 620 applies a force to the moving contact mechanism 500 through the positioning part 526. This force causes the moving contact mechanism 500 to move to the open or closed position. The positioning member 620 and the positioning part 526 re-establish the limiting cooperation, thereby keeping the moving contact mechanism 500 in the open or closed position.

[0124] like Figures 7-10As shown, the positioning component 600 includes a fixedly mounted component support 601, a guide member 630 slidably mounted on the component support 601, and a positioning member main shaft 621; the locking spring is a first spring 623; the positioning member 620 is rotatably mounted on the guide member 630 via the positioning member shaft 621; the first spring 623 cooperates with the guide member 630, and the first spring 623 is used to store energy driven by the guide member 630 and to release energy to drive the guide member 630 to slide. Furthermore, the guide member 630 cooperates with the component support 601 through a first guide limiting structure, so that the guide member 630 can only slide relative to the component support 601 along direction d3.

[0125] Specifically, the component support 601 has a box-shaped structure, including a first side wall 602, a second side wall 604, a bottom side wall 606, and a top side wall 608. Two sets of second side walls 604 are spaced apart along direction d2 and are bent and connected to a pair of sides of the first side wall 602, respectively. The bottom side wall 606 and the top side wall 608 are spaced apart along direction d1 and are bent and connected to the other pair of sides of the first side wall 602, respectively. The first side wall 602 is provided with support holes 603. 3 is used for a portion of the positioning member 620 to pass through and cooperate with the positioning part 526, that is, a portion of the positioning member 620 protrudes outside the component bracket 601 through the bracket hole 603 for cooperation with the positioning part 526; the guide member 630 is slidably placed inside the component bracket 601 along the direction d3; the first spring 623 acts on the guide member 630 to make it tend to slide towards the first side wall 602 of the bracket, that is, when the steady-state mechanism switches from the critical state to the first steady state or the second steady state, the first spring 623 drives the guide member 630 to slide towards the first side wall 602.

[0126] Specifically, the guide member 630 includes a positioning member mounting groove 631 and a positioning member shaft groove 632 disposed on one side thereon, with the two positioning member shaft grooves 632 respectively disposed on both sides of the positioning member mounting groove 631 in the direction d2. A portion of the positioning member 620 is located within the positioning member mounting groove 631. The two ends of the positioning member shaft 621 are rotatably positioned within the two positioning member shaft grooves 632.

[0127] Specifically, the first guide limiting structure includes a positioning member shaft 621 and a bracket guide groove 605 disposed on the second side wall 604 of the bracket, the bracket guide groove 605 extending along direction d3; the two ends of the positioning member shaft 621 are respectively slidably disposed within the bracket guide grooves 605 of the two sets of bracket second side walls 604, thereby improving the stability and reliability of the sliding of the guide member 630. Further, the first guide limiting structure also includes guide bosses 633 disposed on the guide member 630, two sets of guide bosses 633 respectively disposed on a pair of side surfaces of the guide member 630, the guide bosses 633 protruding along direction d2, the two sets of guide bosses 633 respectively slidably disposed within the bracket guide grooves 605 of the two sets of bracket second side walls 604, thereby further improving the stability and reliability of the sliding of the guide member 630. Furthermore, the first guide limiting structure also includes a guide shaft 622, which is inserted into the guide member 630 and protrudes from both ends of the guide member 630. The two ends of the guide shaft 622 are slidably disposed within the bracket guide grooves 605 of the second sidewalls 604 of the two sets of brackets, thereby further improving the stability and reliability of the sliding of the guide member 630. Furthermore, the positioning member pivot 621, guide boss 633, and guide shaft 622 are arranged sequentially along the i.e., direction d3.

[0128] Specifically, the first spring 623 is a compression spring, with one end cooperating with the guide member 630 and the other end cooperating with the housing 100. Furthermore, the guide member 630 also includes a guide spring groove 635 disposed on one side therein, and one end of the first spring 623 is inserted into the guide spring groove 635. Furthermore, the two sets of first springs 623 are arranged side-by-side at intervals along direction d1, thereby ensuring the balance of the force exerted by the first springs 623 on the guide member 630.

[0129] Specifically, the component bracket 601 is fixedly connected to the housing 100. Further, the bottom sidewall 606 of the bracket is provided with a bracket connection hole 607; the housing 100 (specifically the first half-shell 101) is provided with a first connection hole 109 corresponding to and engaging with the bracket connection hole 607; the component fixing screw passes through the first connection hole 109 and is threadedly connected to the bracket connection hole 607, thereby fixing the positioning component 600 to the housing 100 together. Further, the guide member 630 is also provided with a guide member clearance groove 634, which is disposed on the end of the guide member 630 facing the bottom sidewall 606 of the bracket, for clearance of the component fixing screw.

[0130] like Figure 4 , 5As shown in Figures 8-10, the positioning part 526 includes a first surface 527 and a second surface 529, both of which are planar and parallel to direction d2. On a cross-section of the positioning part 526 perpendicular to direction d2, that is, on a cross-section of the positioning part 526 perpendicular to direction d2 (while this cross-section is parallel to directions d1 and d3), the first surface 527 and the second surface 529 are arranged in a V-shape. The opening of the V-shaped structure formed by the first surface 527 and the second surface 529 faces away from the positioning assembly 600.

[0131] The first surface 527 is used to limit and cooperate with the positioning member 620 to hold the moving contact mechanism 500 in the closed position, and is also used to drive the positioning member 620 when the steady-state mechanism switches between the first steady state and the critical state; that is, when the steady-state mechanism is in the first steady state, the first surface 527 is limited and cooperates with the positioning member 620 to hold the moving contact mechanism 500 in the closed position; when the steady-state mechanism switches from the first steady state to the critical state, the first surface 527 and the positioning member 620 are driven through contact, and the positioning member 620 is subjected to The first surface 527 is driven to slide and rotate simultaneously; when the steady-state mechanism switches from the critical state to the first steady state, the first surface 527 and the positioning member 620 are in contact and driven to cooperate. The positioning member 620 slides under the drive of the locking spring. At the same time, the positioning member 620 applies a force to the moving contact mechanism 500 through the first surface 527, causing it to move towards the closed position along the direction d1. This force causes the moving contact mechanism 500 to accelerate along the direction d1, thereby increasing the closing speed. The positioning member 620 also rotates under the drive of the first surface 527.

[0132] The second surface 529 is used to limit and engage with the positioning member 620 to hold the moving contact mechanism 500 in the open position, and is also used to drive the positioning member 620 when the steady-state mechanism switches between the second steady state and the critical state; when the steady-state mechanism is in the second steady state, the second surface 529 is limited and engaged with the positioning member 620 to hold the moving contact mechanism 500 in the open position; when the steady-state mechanism switches from the second steady state to the critical state, the second surface 529 and the positioning member 620 are driven through contact, and the positioning member 620 is subjected to the second... The second surface 529 is driven to slide and rotate simultaneously; when the steady-state mechanism switches from the critical state to the second steady state, the second surface 529 and the positioning member 620 are in contact and driven to cooperate. The positioning member 620 slides under the drive of the locking spring. At the same time, the positioning member 620 applies a force to the moving contact mechanism 500 through the second surface 529, causing it to move towards the disconnected position along the direction d1. This force causes the moving contact mechanism 500 to accelerate along the direction d1, thereby increasing the opening speed. The positioning member 620 also rotates under the drive of the second surface 529.

[0133] like Figure 5As shown, the positioning part 526 further includes a transition surface 528, which is an arc-shaped surface; the first surface 527, the transition surface 528, and the second surface 529 are connected sequentially. The center line of the transition surface 528 is parallel to direction d2 and perpendicular to directions d1 and d3. In the critical state, the transition surface 528 abuts against the positioning member 620, and the center line of the transition surface 528 is coplanar with the rotation axis of the positioning member 620. This plane is parallel to directions d2 and d3 and perpendicular to direction d1. The structure of the positioning part 526 makes the process of switching working states of the stable mechanism smoother and more fluid. Of course, the positioning part 526 may also omit the transition surface 528, and the first surface 527 and the second surface 529 may be directly bent and connected.

[0134] Specifically, the positioning part 526 is disposed on the insulating base 520. Further, the positioning part 526 and the insulating base main board 521 are an integral structure. Further, the insulating base main board 521 has two sets of positioning parts 526 on one side edge and two sets of positioning parts 526 on the other side edge in direction d3; in the first embodiment, the projection direction of the high-speed mechanical switch is the orthogonal projection of direction d1, and the four sets of positioning parts 526 are distributed at the four vertices of a rectangle, respectively cooperating with four sets of positioning components 600. Further, in direction d2, a set of positioning parts 526 is provided on each side of the insulating base guide protrusion of the insulating base main board 521.

[0135] In another embodiment of the positioning component 600 and the positioning part 526, the positioning element 620 of the positioning component 600 is a roller, and the positioning part 526 is an arc-shaped surface, with the roller abutting against the arc-shaped surface; in this embodiment, the projection direction of the high-speed mechanical switch is the orthogonal projection of direction d1, and in the first or second steady state of the steady-state mechanism, the distance between the rotation axis of the roller and the center line of the arc-shaped surface is less than the sum of the radius of the roller and the radius of the arc-shaped surface.

[0136] In another embodiment of the positioning component 600 and the positioning part 526, the positioning element 620 of the positioning component 600 is a roller, and the positioning part 526 is implemented by a roller, with the two rollers abutting each other; in this embodiment, the projection direction of the high-speed mechanical switch is on the orthogonal projection of direction d1, and in the first steady state or the second steady state of the steady-state mechanism, the distance between the rotation axes of the two rollers is less than the sum of the radii of the two rollers.

[0137] In another embodiment of the positioning assembly 600 and the positioning part 526, the positioning member 620 of the positioning assembly 600 adopts a structure similar to that of the positioning part 526. That is, the positioning member 620 has two inclined surfaces, namely a third surface and a fourth surface, which are connected by a transition surface and are also arranged in a V-shape. The V-shaped structure of the positioning member 620 protrudes towards the V-shaped structure of the positioning part 526. In the first stable state, the third surface of the stabilizing mechanism abuts against the first surface 527. In the second stable state, the fourth surface of the stabilizing mechanism abuts against the second surface 529. In the critical state, the transition surface of the positioning member 620 abuts against the transition surface 528 of the positioning part 526.

[0138] As another embodiment of the positioning component 600 and the positioning part 526, the positioning component 600 includes a first surface 527, a transition surface 528 and a second surface 529, and the positioning part 526 includes a positioning member 620 rotatably disposed on the insulating base 520.

[0139] like Figure 2 and 11 As shown, the high-speed mechanical switch of the first embodiment further includes a buffer pad assembly 700. The buffer pad assembly 700 includes at least a first sub-pad 701 disposed between the repulsion disk 500 and the closing coil 300 to reduce the impact of the moving contact mechanism 500 on the closing coil 300 and prevent the closing coil 300 from being damaged by the impact of the moving contact mechanism 500. Furthermore, the buffer pad assembly 700 also includes a second sub-pad 702 disposed between the insulating base 520 and the first bottom wall 108 of the housing 100 to reduce the impact of the moving contact mechanism 500 on the housing 100 and prevent the housing 100 from being damaged by the impact of the moving contact mechanism 500.

[0140] Specifically, the first sub-pad 701 is an annular pad, which is sleeved on the housing guide post 106 of the housing 100; the first sub-pad 701 is stacked on the closing coil 300.

[0141] Specifically, the second sub-pad 702 has a second sub-pad hole through which the insulating seat guide portion 524 of the insulating seat 520 passes. Further, the housing 100 has a second sub-pad groove, which is located radially outside the entrance of the housing guide hole 104, for the second sub-pad 702 to be placed therein; the side of the second sub-pad 702 that mates with the insulating seat 520 is higher than the entrance of the housing guide hole 104.

[0142] It should be noted that the buffer pad assembly 700 and the buffer spring disposed in the insulating seat guide portion 524 of the insulating seat 520 can be provided simultaneously or selectively.

[0143] like Figures 12-13 The image shows one embodiment of the housing 100.

[0144] like Figure 12 As shown, the first half-shell 101 includes a first front wall 117 and a first rear wall 118 arranged opposite each other along direction d3, a first left wall 119 and a first right wall 120 arranged opposite each other along direction d2, and a first bottom wall 108. The first front wall 117, the first left wall 119, the first rear wall 118, and the first right wall 120 are connected end to end in sequence, and one end of each is connected to the first bottom wall 108, forming a box-shaped structure with one open end. The first front wall 117 and the first rear wall 118 are each provided with a second housing groove 103 for accommodating the corresponding positioning component 600, and the first bottom wall 108 is provided with a first connecting hole 109 corresponding to each second housing groove 103. The first left wall 119 and the second right wall 120 are each provided with a first housing groove 102 for accommodating the corresponding insulating seat connecting arm 522. The first bottom wall 108 is provided with a closing coil groove 105 for accommodating the closing coil 300, and a housing guide post 106 is provided in the middle of the closing coil groove 105. Preferably, the first bottom wall 108 is further provided with a first wiring groove 111, which communicates with the closing coil groove 105. The first front wall 117 is provided with a first connection port 110, which is used for the wire connected to the closing coil 300 to enter and connect to the closing coil 300, or for the lead wire of the closing coil 300 to extend out. One end of the first wiring groove 111 is connected to the first connection port 110, and the first wiring groove 111 is used to arrange the wire connected to the closing coil 300 or to arrange the lead wire of the closing coil 300. The first bottom wall 108 is provided with a housing guide hole 104. The first front wall 117 and the first rear wall 118 are both provided with a third groove 107 and a fourth groove 112. The third groove 107 is used to cooperate with the insulating seat guide protrusion of the insulating seat 520 and the repulsion disk guide protrusion 554 of the repulsion disk 550. The fourth groove 112 is used to cooperate with the moving contact guide protrusion of the moving contact 510.

[0145] Specifically, the first half-shell 101, except for the first wiring groove 111 and the first connection port 110, has a centrally symmetrical structure with the axis of the shell guide post 106 as the axis of symmetry.

[0146] like Figure 13As shown, the second half-shell 130 includes two stationary contact mounting slots, a trip coil slot 133, and a second wiring port 134. The two stationary contact mounting slots, respectively, are used to accommodate the ends of the first stationary contact 201 and the second stationary contact 202 that have stationary contact points. These are the first stationary contact mounting slot 131 and the second stationary contact mounting slot 132. The two stationary contact mounting slots are respectively located at both ends of the second half-shell 130 in direction d2 and are both located on the side of the second half-shell 130 facing the first half-shell 101 in direction d1. The second wiring port 134 is located on the front sidewall of the second half-shell 130 and is used for the entry of wires connected to the trip coil 400 for connection to the trip coil 400, or for the extension of the leads of the trip coil 400. The trip coil slot 133 is located on the side of the second half-shell 130 facing the first half-shell 101 and communicates with the second wiring port 134. Furthermore, the second half-shell 130 also includes a second wiring groove 135 disposed on the bottom wall of the trip coil groove 133. The second wiring groove 135 communicates with the trip coil groove 133 and one end is connected to the second terminal 134, for arranging the wires connected to the trip coil 400 or the leads of the trip coil 400. The second half-shell 130 is fixedly connected to the first half-shell 101 by a connecting screw.

[0147] like Figures 14-25 The figure shows a second embodiment of the high-speed mechanical switch of the present invention.

[0148] like Figure 15 , 16 As shown in Figures 19 and 21-23, a key difference between the high-speed mechanical switch of the second embodiment and the high-speed mechanical switch of the first embodiment lies in the different arrangement and structure of their steady-state mechanisms. In the high-speed mechanical switch of the second embodiment, the positioning part 526 is fixedly arranged, and the positioning component 600 is configured to move synchronously with the moving contact mechanism 500.

[0149] like Figures 15-19As shown in Figures 21-23, the positioning assembly 600 also includes a guide member 630, a positioning member 620, and a positioning member shaft 621. The positioning member 620 is rotatably mounted on the guide member 630 via the positioning member shaft 621. The guide member 630 is linearly slidably mounted on the moving contact mechanism 500. The locking spring cooperates with the guide member 630, storing or releasing energy under the drive of the guide member 630 to drive the guide member 630 to slide. The sliding direction of the positioning member 620 (which is also the sliding direction of the guide member 630) is direction d2, and the direction of the shaft of the positioning member 620 is direction d3. Further, the insulating base main board 521 is provided with a guide member mounting hole 560, and the guide member 630 is slidably mounted within the guide member mounting hole 560. Further, the locking spring is also mounted within the guide member mounting hole 560. Furthermore, the positioning component 600 also includes a stop 670, which is used to limit the guide 630 and prevent the guide 630 from dislodging from the guide mounting hole 560. The positioning component 600 and the moving contact mechanism 500 are assembled into an integral structure, which significantly improves the structural compactness of the high-speed mechanical switch and reduces the size of the high-speed mechanical switch.

[0150] Specifically, the guide member 630 includes a guide member body 641 and at least one set of guide member limiting parts 642. The guide member body 641 has a cylindrical structure, and each set of guide member limiting parts 642 is disposed on one radial side of the guide member body 641. The insulating base main board 521 also includes a guide member limiting groove 561, which is disposed on the side wall of the guide member mounting hole 560 and communicates with it. The guide member limiting parts 642 are slidably disposed in the guide member limiting groove 561, so that the guide member 630 can only slide along direction d2 and cannot rotate around the axis of the guide member body 641. The positioning member 620 is rotatably disposed on one axial end of the guide member body 641 through a positioning member pivot 621, and the other axial end of the guide member body 641 cooperates with a locking spring. Further, the guide member 630 is provided with two sets of guide member limiting parts 642, which are respectively disposed on the radial sides of the guide member body 641. Furthermore, the cross-section of the guide limiting part 642 perpendicular to the axial direction of the guide 630 is a square boss structure, and the shape of the corresponding guide limiting groove 561 is adapted to the shape of the guide limiting part 642, that is, the cross-section of the guide limiting groove 561 perpendicular to the axial direction of the guide 630 is a square groove structure. Furthermore, in the guide 630, one end of each of the two sets of guide limiting parts 642 extends to both sides of the corresponding positioning part 620 to form two positioning part mounting arms 644. The two mounting part positioning arms 644 are used for inserting the two ends of the corresponding positioning part rotating shaft 621 onto them.

[0151] It should be noted that the guide limiting part 642 is not limited to the above-described implementation. For example, the guide limiting part 642 can be a plate-like structure disposed on the guide body 641, and the guide limiting groove 561 can be a narrow groove; or, the guide body 641 can be a polygonal column structure, and the guide mounting hole 560 can be a polygonal hole, and the two together can prevent the guide body 641 from rotating. Those skilled in the art can also make various modifications based on conventional technical means, which will not be listed here. All modifications should fall within the protection scope of this application.

[0152] Specifically, the insulating base main board 521 also includes a stop mounting groove 563, which is connected to the guide limiting groove 561; the stop 670 is inserted into the stop mounting groove 563; the stop limiting part 642 is provided with a guide limiting step 643, which abuts and limits the stop 670 along the direction d2. Furthermore, the stop 670 has an overall U-shaped structure, including a stop beam 671 and stop legs 672. The two ends of the stop beam 671 are bent and connected to two sets of stop legs 672, which are arranged opposite to each other. After the stop 670 is installed in the stop mounting groove 563, the two sets of stop legs 672 are respectively positioned on both sides of the corresponding two sets of guide limiting parts 642 on the radial direction (specifically, direction d3) of the guide body 641, respectively, and are respectively limited and cooperated with the guide limiting steps 643 of the corresponding two sets of guide limiting parts 642, improving the reliability of the stop 670 in limiting the guide 630. Furthermore, the side wall of the stop mounting groove 563 is provided with a stop slot 564; the stop leg 672 is provided with a stop hook 673; the stop hook 673 is used to engage in the stop slot 564, preventing the stop 670 from dislodging from the stop mounting groove 563.

[0153] Specifically, the direction in which the stop 670 is inserted into the stop mounting groove 563 is perpendicular to the sliding direction of the guide 630. Further, the direction in which the stop 670 is inserted into the stop mounting groove 563 is direction d1, that is, during assembly, the stop 670 is inserted into the stop mounting groove 563 along direction d1.

[0154] Specifically, the stop beam 671 is provided with a beam groove 674, which is located on the side of the stop beam 671 facing the guide member 630. The beam groove 674 is an arc-shaped groove that is adapted to the outer diameter of the guide member body 641.

[0155] It should be noted that the stop 670 is not limited to the above-described implementation. For example, the stop pin 670 can also be a limiting pin, and the guide body 641 of the guide 630 is provided with an oblong hole for the limiting pin to pass through. The two ends of the limiting pin are respectively fixed on the insulating base main board 521. Those skilled in the art can make various other modifications using conventional techniques, which will not be listed here. All modifications should fall within the protection scope of this application.

[0156] like Figure 16 , 17 As shown, a pair of sidewalls at the entrance end of the guide mounting hole 560 are provided with shaft guide grooves 562; the two ends of the positioning shaft 621 are respectively slidably disposed in the corresponding two sets of shaft guide grooves 562, which further improves the reliability and stability of the sliding of the guide 630.

[0157] like Figure 16 , 19 As shown in Figures 21-23, the high-speed mechanical switch of the second embodiment includes two sets of steady-state mechanisms. The positioning components 600 of the two sets of steady-state mechanisms are a left positioning component 640 and a right positioning component 660, respectively. The guide members 630 of the left positioning component 640 and the right positioning component 660 are arranged sequentially along direction d2. The locking spring is a second spring 650, which cooperates with the two sets of guide members 630 respectively. The two guide members 630 are slidably inserted into the two ends of the guide member mounting hole 560.

[0158] Specifically, the second spring 650 is a linear compression spring; the guide body 641 is provided with guide spring holes 645; the two ends of the second spring 650 are respectively inserted into the two guide spring holes 645, and the two guides 630 are spaced apart. When the steady-state mechanism switches from the first steady state or the second steady state to the critical state, the two guides 630 slide towards each other, compressing the second spring 650 to store energy; when the steady-state mechanism switches from the critical state to the first steady state or the second steady state, the second compression spring 650 releases energy and drives the two guides 630 to slide in opposite directions.

[0159] Specifically, the two sets of positioning components 600 have the same structure, which reduces the types of parts and lowers manufacturing costs.

[0160] like Figures 16-18 As shown, the insulating base 520 also includes an insulating base sliding portion 565. Each insulating base connecting arm 522 has an insulating base sliding portion 565 on one side. The insulating base sliding portion 565 has an arc-shaped protrusion structure for sliding cooperation with the housing 100, which helps to reduce the contact resistance between the insulating base 520 and the housing 100 and ensures the reliability and stability of the moving contact mechanism 500. The insulating base connecting arm 522 does not have the connecting arm sliding rib 531 of the high-speed mechanical switch in the first embodiment.

[0161] Specifically, each of the insulating seat connecting arms 522 is provided with two insulating seat sliding parts 565, which are arranged side by side at intervals along direction d3 and located on both sides of the corresponding positioning component 600.

[0162] like Figure 17 As shown, the insulating base main board 521 is also provided with multiple insulating base square holes, each insulating base hole is arranged sequentially along direction d2, and each insulating base hole is connected to the guide component mounting hole 560, which improves the convenience of mold demolding, reduces the undercut features of parts, reduces the difficulty of mold manufacturing, and also reduces the amount of raw materials used in the insulating base 520, saving manufacturing costs.

[0163] like Figure 16 , 17 As shown, in the high-speed mechanical switch of the second embodiment, the moving contact mechanism 500 is provided with two sets of overtravel components 540. The two sets of overtravel components 540 are arranged side by side and spaced apart along the direction d3. The two sets of overtravel components 540 are located on both sides of the positioning component 600 in the direction d3.

[0164] like Figure 16 , 17 As shown in Figures 21-24, in the high-speed mechanical switch of the second embodiment, the insulating base 520 does not have the insulating base guide portion 524 and the insulating base guide hole 537 of the high-speed mechanical switch of the first embodiment, and the corresponding housing 100 does not have the housing guide hole 104 and the housing guide post 106 of the high-speed mechanical switch of the first embodiment.

[0165] like Figure 15 , 21 As shown in Figure 25, the positioning part 526 is disposed on the housing 100, and has the same structure as the positioning part 526 of the high-speed mechanical switch in the first embodiment. Furthermore, two sets of the positioning parts 526 are respectively disposed on a pair of side walls of the housing 100.

[0166] Specifically, one end of the positioning part 526 is disposed on the first half-shell 101, and the other end extends toward the second half-shell 130 and protrudes from one side of the first half-shell 101; the second half-shell 130 is provided with a mating groove 139, and the free end of the positioning part 526 (i.e., the end of the positioning part 526 extending toward the second half-shell 130) is embedded in the mating groove 139. The positioning part 526 and the first half-shell 101 are an integral structure.

[0167] like Figure 24 , 25 As shown, another important difference between the high-speed mechanical switch of the second embodiment and the high-speed mechanical switch of the first embodiment is that the structure of the housing 100 is different.

[0168] like Figure 24 , 25As shown, in the housing 100, the first housing 101 and the second housing 103 are assembled and joined together along the direction d3, that is, the first housing 101 and the second housing 103 are assembled together along the direction d3 to form the housing 100.

[0169] like Figure 24 , 25 As shown, the housing 100 has a closing coil cavity, a moving contact mounting cavity, and a opening coil cavity arranged sequentially along direction d1. These three cavities are independent and isolated from each other. The closing coil cavity accommodates the closing coil 300, the moving contact mounting cavity accommodates the moving contact mechanism, and the opening coil cavity accommodates the opening coil 400. This arrangement of the closing coil cavity, moving contact mounting cavity, and opening coil cavity improves the insulation performance of the high-speed mechanical switch.

[0170] Specifically, the closing coil cavity includes a rear half-cavity 114 of the closing coil disposed on the first housing 101 and a front half-cavity 137 of the closing coil disposed on the second housing 130. The rear half-cavity 114 and the front half-cavity 137 of the closing coil are joined together relative to each other along direction d3 to form the closing coil cavity. The moving contact mounting cavity includes a rear half-cavity 115 of the moving contact disposed on the first housing 101 and a front half-cavity 138 of the moving contact disposed on the second housing 130. The rear half-cavity 115 and the front half-cavity 138 of the moving contact are joined together relative to each other along direction d3 to form the moving contact mounting cavity. The opening coil cavity includes a rear half-cavity 113 of the opening coil disposed on the first housing 101 and a front half-cavity 136 of the opening coil disposed on the second housing 130.

The first wiring port 110 and the second wiring port 134 are both located on the second half-shell 130. The first wiring port 110 is connected to the closing coil cavity, and the second wiring port 134 is connected to the opening coil cavity.

[0171] like Figure 24 , 25 As shown, the first stationary contact mounting groove 131 is formed by two half-grooves respectively disposed on the first half-shell 101 and the second half-shell 130, joined together along direction d3, and the first stationary contact mounting groove 131 communicates with the moving contact mounting cavity. The second stationary contact mounting groove 132 is formed by two half-grooves respectively disposed on the first half-shell 101 and the second half-shell 130, joined together along direction d3, and the second stationary contact mounting groove 132 communicates with the moving contact mounting cavity.

[0172] like Figures 26-29 The figure shown is a third embodiment of the high-speed mechanical switch of the present invention.

[0173] The main difference between the high-speed mechanical switch in the third embodiment and the high-speed mechanical switch in the second embodiment is that the two have different implementation methods for their steady-state mechanisms.

[0174] like Figures 27-29 As shown, the steady-state mechanism includes a positioning spring 800, with a fixed pivot end and a movable engagement end at its two ends. The fixed pivot end is rotatably mounted on the housing 100 (specifically, the first half-shell 101), and the movable engagement end is rotatably mounted on the moving contact mechanism 500. The positioning spring 800 rotates around the fixed pivot end as the moving contact mechanism 500 moves, thereby switching the steady-state mechanism between a first steady state, a critical state, and a second steady state. The positioning spring 800 has a first energy release position, a dead point position, and a second energy release position, corresponding to the first steady state, the critical state, and the second steady state, respectively. When the positioning spring 800 is in the dead point position, the direction of the force exerted by the positioning spring 800 on the moving contact mechanism 500 is perpendicular to direction d1. The positioning spring 800 is configured to store energy to its maximum value when the steady-state mechanism is in the critical state; that is, when the steady-state mechanism is in the critical state, the positioning spring 800 is in the dead point position and the positioning spring 800 has stored energy to its maximum value.

[0175] The positioning spring 800 is configured as follows:

[0176] When the steady-state mechanism switches from the first steady state or the second steady state to the critical state, it is driven by the moving contact mechanism 500 to rotate around the fixed pivot end and simultaneously store energy; and...

[0177] When the steady-state mechanism switches from the critical state to the first steady state or the second steady state, it releases energy around the fixed pivot end to drive the moving contact mechanism 500 to move to the closed position or the open position.

[0178] Specifically, the positioning spring 800 is located in direction d2 between the side wall of the housing 100 (specifically the first half-shell 101) and the moving contact mechanism 500. When the positioning spring 800 is in the dead position, the direction of the force exerted by the positioning spring 800 on the moving contact mechanism 500 is perpendicular to directions d1 and d3 and parallel to direction d2. The swing plane of the positioning spring 800 is perpendicular to direction d3 and parallel to directions d2 and d1. Further, the positioning spring 800 is a linear compression spring, and when the positioning spring 800 is in the dead position, the geometric axis of the positioning spring 800 is perpendicular to directions d1 and d3 and parallel to direction d2.

[0179] In another embodiment of the positioning spring 800, the positioning spring 800 is a torsion spring, with one spring arm rotatably mounted on the housing 100 and the other spring arm rotatably mounted on the moving contact mechanism 500.

[0180] Specifically, in the positioning spring 800, the fixed pivot end is rotatably mounted on the housing 100, and the movable mating end is rotatably mounted on the insulating seat sidewall 522 of the insulating seat 520. The insulating seat connecting arm 522 is provided with a spring support groove 548, and the movable mating end of the positioning spring 800 is disposed in the spring support groove 548.

[0181] Specifically, the housing 100 is provided with a spring cavity 140, in which a positioning spring 800 is oscillating.

[0182] Specifically, the high-speed mechanical switch in the third embodiment has two sets of steady-state mechanisms, which are located on both sides of the moving contact mechanism 500 in the direction d2. Furthermore, the two sets of steady-state mechanisms are symmetrically arranged.

[0183] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship conventionally placed during use.

[0184] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
