Description

Technical Field

[0001] This application relates to an operating mechanism for a disconnector switch. Background Technology

[0002] Currently, an increasing number of switches, especially in the photovoltaic field, are equipped with electrically operated mechanisms for remote control. These switches typically possess both manual and electrically operated functions, allowing for both manual on-site operation and remote control. To achieve the goal of adding an electrically operated mechanism to disconnect switches, the conventional approach is to superimpose the electrically operated mechanism onto the existing manual operating mechanism. Through mechanical coupling between the two mechanisms, both manual and electrically operated switching can be achieved. However, this superimposed structure directly increases the overall size of the operating mechanism, significantly increasing the overall size of the switch and affecting its installation adaptability in confined spaces (such as photovoltaic combiner boxes and distribution cabinets). Therefore, there is an urgent need for a compact disconnect switch operating mechanism that is compatible with both manual and electrically operated modes. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a disconnector switch operating mechanism.

[0004] To achieve the above objectives, the technical solution of this application is as follows: A disconnector switch operating mechanism includes: a housing with a receiving cavity inside, a drive shaft with its central axis arranged along a first direction, an electric operating mechanism and a transmission mechanism arranged sequentially along the first direction and sleeved outside the drive shaft, and an output component located on the side of the transmission mechanism away from the electric operating mechanism along the first direction; the electric operating mechanism is connected to the drive shaft for transmission so that it can drive the drive shaft to rotate around its central axis; the transmission mechanism includes a first slider, a second slider, and an energy storage spring connected between the first slider and the second slider, the first slider being confined within the housing so that it can only slide along a second direction, the second slider being confined within the housing so that it can only slide along a second direction; the energy storage spring being confined between the first slider and the second slider and can only slide along the second direction. The first slider has two first working parts located on the outer sides of both ends of the energy storage spring along the first direction, and the second slider has two second working parts located on the outer sides of both ends of the energy storage spring along the first direction. When the first slider and the second slider slide relative to each other, the energy storage spring performs compression or extension action along the second direction. The first slider is driven and linked with the drive shaft, and the second slider is driven and linked with the output component. A locking mechanism is provided in the housing to lock the second slider before the energy storage spring completes energy storage, so that it remains stationary during the energy storage process. It is also configured to release the lock on the second slider after the energy storage spring completes energy storage, so that the second slider and the first slider slide relative to each other along the second direction under the energy release action of the energy storage spring. The first direction is perpendicular to the second direction.

[0005] Furthermore, the first slider and the second slider are arranged sequentially along the first direction. The first slider is provided with a first limiting groove arranged along the second direction, and the second slider is provided with a second limiting groove arranged along the second direction. The positions of the first limiting groove and the second limiting groove along the first direction are corresponding. The two ends of the first limiting groove along the second direction constitute the first functional part, and the two ends of the second limiting groove along the second direction constitute the second functional part.

[0006] Furthermore, two energy storage springs are provided, and a first limiting groove is provided on each side of the first slider along the second direction to accommodate the two energy storage springs.

[0007] Furthermore, the transmission mechanism also includes a third slider, which is connected to the second slider by a connecting column to form a linkage and a limiting cavity between them for the first slider to slide along the second direction. The third slider is provided with a first through hole for the drive shaft to pass through and slide.

[0008] Furthermore, the first limiting groove is a through groove extending along the first direction, and the third slider is provided with a third limiting groove arranged along the second direction. The third limiting groove, the first limiting groove, and the second limiting groove are positioned in the first direction to correspond to each other, so that the three are connected to form a limiting cavity for accommodating the energy storage spring. The third slider and the second slider limit the energy storage spring at both ends along the first direction. There are two energy storage springs. The first slider is provided with a first limiting groove arranged along the second direction on each side to accommodate the two energy storage springs.

[0009] Furthermore, the locking mechanism includes two locking blocks and an unlocking cam. The locking blocks have locking portions. The two locking blocks are arranged at intervals along a second direction and are located on one side of the third slider or the second slider. The third slider or the second slider is provided with a first limiting groove and a second limiting groove. The locking blocks are pivotally supported and fitted with elastic members, and their pivot axis is set along the first direction, so that they always have a tendency to rotate towards the third slider or the second slider when no external force is applied. The unlocking cam is coaxially linked with the drive shaft. When it rotates in the forward direction and in the reverse direction, its contour surface can push the two locking blocks to overcome the elastic force of the elastic members and rotate them away from the third slider or the second slider. Before the energy storage spring completes energy storage, the locking portion of one of the locking blocks is embedded in the first slot or the second slot. After the energy storage spring completes energy storage, the locking block is pushed by the unlocking cam to make its locking portion leave the corresponding slot. After the energy storage spring completes energy release, the locking portion of the other locking block is embedded in the second slot or the first slot.

[0010] Furthermore, a limiting wall is provided on the inner side of the housing. The limiting wall and the inner wall on the opposite side of the housing form a limiting sliding cavity that is adapted to the shape of the third slider and the second slider. The limiting wall forms a mounting groove on one side of the third slider, and both locking blocks can be pivotally supported in the mounting groove.

[0011] Furthermore, the locking block has a pushing part located on the side of the third slider along the first direction. When the locking block is pushed away from the first limiting groove by the unlocking cam, the pushing part remains on the side of the third slider along the first direction.

[0012] Furthermore, the first slider has a mating groove on the side near the third slider, and a second transmission gear and a rack extending in the second direction are provided in the mating groove. The second transmission gear is sleeved on the outside of the drive shaft and rotates synchronously with the drive shaft. The rack meshes with the second transmission gear and is linked to the first slider.

[0013] Furthermore, the output component is pivotally supported between the housing and the transmission mechanism, and its pivot center axis is set along the first direction. It has a protrusion on the side near the transmission mechanism that is a certain distance away from its pivot center axis and protrudes towards the transmission mechanism. The second slider has a drive groove for the protrusion to be inserted into, so that it can slide linearly along the second direction to drive the output component to rotate.

[0014] Furthermore, the output component is a cam structure, and a tripping detection switch and a closing detection switch are fixed between the housing and the transmission mechanism. The two switches correspond to the two extreme positions of the cam profile of the output component, respectively.

[0015] The beneficial effects of this application are as follows: The disconnector operating mechanism of this application optimizes the structural space layout through structural improvements to the transmission mechanism, avoiding the problem of increased overall volume caused by the superimposed structure in the prior art, making the mechanism structure more compact and improving its installation adaptability in confined spaces; the energy storage spring in the transmission mechanism cooperates with the locking mechanism to realize the energy storage and release action during operation, ensuring the reliability of the opening and closing operation; at the same time, the mechanism design is compatible with both manual and electric dual-mode operation, meeting the opening and closing requirements of on-site manual drive and remote electric control, and is applicable to a wide range of scenarios.

The appearance of the above words in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0039] To address the problems in related technologies, embodiments of this application provide a disconnector switch operating mechanism, such as... Figure 1 As shown, it includes a housing 100, a drive shaft 200, an electric operating mechanism 300, a transmission mechanism 400, and an output component 500. The housing 100 has a receiving cavity for mounting the drive shaft 200, the electric operating mechanism 300, the transmission mechanism 400, and the output component 500. The drive shaft 200 is a central axis extending along a first direction and is used to input driving force. The electric operating mechanism 300 and the transmission mechanism 400 are sleeved around the drive shaft 200 and arranged sequentially along the first direction. The output component 500 is located on the side of the transmission mechanism 400 away from the electric operating mechanism along the first direction.

[0040] The electric operating mechanism 300 can employ a geared motor assembly as used in the prior art, which is connected to the drive shaft 200 to drive the drive shaft 200 to rotate around its central axis, allowing the drive shaft 200 to be driven manually or electrically. Specifically, the two can be coupled by a gear transmission.

[0041] like Figures 3-5 As shown, the transmission mechanism 400 includes a first slider 410, a second slider 420, and an energy storage spring 430 connected between the first slider 410 and the second slider 420. The first slider 410 is confined within the housing 100 so that it can only slide in a second direction, and the second slider 420 is confined within the housing 100 so that it can only slide in a second direction. The energy storage spring 430 is confined between the first slider 410 and the second slider 420 and can only be compressed or extended in the second direction. The first slider 410 has two first actuating portions 411 respectively located on the outer sides of both ends of the energy storage spring 430 along the first direction, and the second slider 420 has two second actuating portions respectively located on the outer sides of both ends of the energy storage spring 430 along the first direction. 421. When the first slider 410 and the second slider 420 slide relative to each other, the energy storage spring 430 performs a compression or extension action along the second direction; the first slider 410 is driven by the drive shaft 200 to form a linkage, and the second slider 420 is driven by the output component 500 to form a linkage; the locking mechanism 600, which is located in the housing 100, is used to lock the second slider 420 before the energy storage spring 430 completes energy storage so that it remains stationary during the energy storage process, and is also configured to release the lock on the second slider 420 after the energy storage spring 430 completes energy storage so that the second slider 420 and the first slider 410 slide relative to each other along the second direction under the energy release action of the energy storage spring 430; the first direction is perpendicular to the second direction. With the above structural design, when the drive shaft 200 is driven manually or electrically, the rotation of the drive shaft 200 causes the first slider 410 to slide unidirectionally along the second direction, compressing the energy storage spring 430; at this time, the locking mechanism 600 keeps the second slider 420 stationary until the energy storage spring 430 reaches the preset compression amount; then the locking mechanism 600 unlocks instantly, the energy storage spring 430 releases energy quickly, pushing the second slider 420 to slide at high speed along the second direction, driving the output component 500 to complete the opening or closing action; this process is responsive and energy transfer is efficient.

[0042] The working process is as follows: During electric operation, the electric operating mechanism 300 drives the drive shaft 200 to rotate, and the drive shaft 200 drives the first slider 410 to slide along the second direction. At this time, the locking mechanism 600 is in a locked state, and the second slider 420 remains stationary. During the sliding process of the first slider 410 relative to the second slider 420, the first action part 411 and the second action part 421 cooperate to compress the energy storage spring 430, causing the energy storage spring 430 to compress and store energy along the second direction. When the energy storage spring 430 has completed energy storage, the locking mechanism 600 releases the lock on the second slider 420, the energy storage spring 430 releases energy, and pushes the first slider 410 and the second slider 420 to slide relative to each other along the second direction. The second slider 420 drives the output component 500 to move, realizing the opening and closing operation of the disconnecting switch. During manual operation, a manual operation interface can be provided at the end of the drive shaft 200 extending out of the housing. The drive shaft 200 can be rotated by means of an external operating handle, and the subsequent transmission process is the same as that of electric operation.

[0043] This technical solution arranges the electric operating mechanism 300, the transmission mechanism 400, and the output component 500 sequentially along the first direction (the central axis direction of the drive shaft 200), and further optimizes the structure of the transmission mechanism 400 to maintain its original transmission and drive function while significantly reducing the radial space occupied, forming a compact structure with axial stacking. This greatly reduces the overall radial dimension of the operating mechanism and improves its installation adaptability in narrow spaces such as photovoltaic combiner boxes and distribution cabinets.

[0044] Optionally, in some embodiments, the first slider 410 and the second slider 420 are arranged sequentially along the first direction. The first slider 410 is provided with a first limiting groove 412 arranged along the second direction, and the second slider 420 is provided with a second limiting groove 422 arranged along the second direction. The positions of the first limiting groove 412 and the second limiting groove 422 along the first direction are corresponding. The two ends of the first limiting groove 412 along the second direction constitute a first working part 411, and the two ends of the second limiting groove 422 along the second direction constitute a second working part 421. Specifically, the energy storage spring 430 is a conventional spring with a circular cross-section. It is installed within the annular space formed by the first limiting groove 412 and the second limiting groove 422. Its two ends along the second direction abut against the first actuating part 411 of the first limiting groove 412 and the second actuating part 421 of the second limiting groove 422, respectively. This allows for precise control of the relative displacement between the first slider 410 and the second slider 420 on the length of the energy storage spring 430, thereby achieving efficient energy storage and instantaneous release. The groove structure integrates the actuating part, eliminating the need for additional actuating part components and improving assembly efficiency. Simultaneously, the groove structure ensures more uniform force distribution on the energy storage spring 430, reducing fatigue wear and extending its service life.

[0045] Optionally, in some embodiments, a third slider 440 is further included. The third slider 440 and the second slider 420 are connected by a connecting post 423 to form a linkage engagement, and a limiting cavity is formed between them for the first slider 410 to slide along the second direction. The third slider 440 is provided with a first through hole 443 for the drive shaft 200 to pass through and slide. Specifically, the first through hole 443 is an elongated through hole extending along the second direction, and its width is adapted to the outer diameter of the drive shaft 200, so that the drive shaft 200 can pass through the first through hole 443 and engage with the first slider 410 for transmission. Its length is at least greater than the sliding stroke of the third slider 440 along the second direction, ensuring that the drive shaft 200 does not interfere with the sliding of the third slider 440 during the entire movement. Preferably, the connecting post 423 is a stud, which realizes a detachable connection and facilitates later maintenance and component replacement. The limiting cavity formed by the third slider 440 and the second slider 420 plays a precise guiding and limiting role for the first slider 410, ensuring that the first slider 410 always slides smoothly along the second direction, avoiding its deviation and transmission jamming, and improving the motion reliability of the transmission mechanism.

[0046] Optionally, in some embodiments, the first limiting groove 412 is a through groove extending along the first direction, and the third slider 440 is provided with a third limiting groove 442 arranged along the second direction. The third limiting groove 442 corresponds to the positions of the first limiting groove 412 and the second limiting groove 422 along the first direction, so that the three are connected to form a limiting cavity for accommodating the energy storage spring 430, and the third slider 440 and the second slider 420 limit the energy storage spring 430 at both ends along the first direction. The energy storage spring 430 is installed in the limiting cavity, and its two ends contact the walls of the third limiting groove 442 and the second limiting groove 422 respectively, thereby achieving limitation at both ends along the first direction. With the above structure, the overall thickness of the transmission mechanism 400 can be reduced in the first direction, further achieving a compact layout.

[0047] Optionally, in some embodiments, two energy storage springs 430 are provided. A first limiting groove 412, arranged along a second direction, is provided on each side of the first slider 410 to accommodate the two energy storage springs 430. The two energy storage springs 430 are symmetrically arranged on both sides of the first slider 410. Correspondingly, two limiting grooves are also provided on the second slider 420 and the third slider 440, ensuring that the two energy storage springs 430 compress and extend synchronously. The symmetrical arrangement of the two energy storage springs 430 makes the force between the first slider 410 and the second slider 420 more balanced, reducing deformation caused by excessive force on a single spring, and improving the service life and motion stability of the transmission mechanism. Furthermore, for the same opening and closing driving force design requirements, the dual-spring configuration can reduce the elasticity requirement of a single spring, thereby reducing the spring volume and installation space, conforming to the development trend of lightweight and miniaturized overall machine.

[0048] Alternatively, in some embodiments, such as Figures 8-11 As shown, the locking mechanism 600 includes two locking blocks 610 and an unlocking cam 620. The locking blocks 610 have a locking part 611. The two locking blocks 610 are arranged at intervals along a second direction and are located on one side of the third slider 440 or the second slider 420. The third slider 440 or the second slider 420 is provided with a first slot 631 and a second slot 632. The locking blocks 610 are pivotally supported and are engaged with an elastic member 640, and their pivot axis is set along the first direction, so that they always have a tendency to rotate in the direction closer to the third slider 440 or the second slider 420 when no external force is applied. The unlocking cam 620 is coaxially linked with the drive shaft 200. When it rotates in the forward direction and in the reverse direction, its contour surface can push the two locking blocks 610 to overcome the elastic force of the elastic member 640, so that they rotate in the direction away from the third slider 440 or the second slider 420.

[0049] Specifically, in one embodiment, when the drive shaft 200 rotates in the forward direction, before the energy storage spring 430 completes energy storage, the locking part 611 of one locking block 610 is inserted into the corresponding first slot 631; after the energy storage spring 430 completes energy storage, the locking block 610 is pushed by the unlocking cam 620 to disengage its locking part 611 from the first slot 631; after the energy storage spring 430 completes energy release, the locking part 611 of the other locking block 610 is inserted into the second slot 632 of the other. Conversely, the actions are performed in the opposite order.

[0050] Locking block 610 is pivotally mounted on housing 100, as follows: Figure 10As shown, the locking block 610 has a pivot hole 613 for a pivot to pass through. The axis of the pivot is set along a first direction, allowing the locking block 610 to rotate about the pivot in a plane perpendicular to the first direction. The locking part 611 is a pointed corner of the end of the locking block 610, which is adapted to the shape of the first slot 631 and the second slot 632. The unlocking cam 620 is connected to the drive shaft 200 by a key and rotates synchronously with the drive shaft 200. Its profile is a non-circular structure with two protrusions, corresponding to the two locking blocks 610 respectively. When the drive shaft 200 rotates forward to drive the energy storage spring 430 to store energy, one of the pushing parts of the unlocking cam 620 gradually approaches the corresponding locking block 610. When energy storage is complete, it pushes the locking block 610 to rotate, causing its locking part 611 to disengage from the first slot 631. When the energy storage spring 430 releases energy and drives the second slider 420 and the third slider 440 to slide to their limit positions, the locking part 611 of the other locking block 610 is engaged in the second slot 632 under the action of the elastic member 640, thus achieving locking. The combination structure of two locking blocks 610 and the unlocking cam 620 achieves bidirectional locking during the energy storage process and after the energy release is completed, improving the working reliability of the operating mechanism. The unlocking cam 620 is coaxially linked with the drive shaft 200, eliminating the need for additional drive components, simplifying the structure of the locking mechanism and reducing costs.

[0051] Alternatively, in some embodiments, such as Figure 9As shown, a limiting wall 110 is provided on the inner side of the housing 100. The limiting wall 110 and the inner wall on the opposite side of the housing 100 form a limiting sliding cavity that is adapted to the shape of the third slider 440 and the second slider 420. The limiting wall 110 forms a mounting groove 111 on one side of the third slider 440, and both locking blocks 610 can be pivotally supported in the mounting groove 111. Specifically, the limiting wall 110 is an integrally formed inner wall of the housing 100, extending along the first direction. The distance between it and the inner wall on the other side of the housing 100 is adapted to the width of the third slider 440 and the second slider 420 along the perpendicular direction, forming a limiting sliding cavity. This sliding cavity can limit the lateral displacement of the third slider 440 and the second slider 420, ensuring that they slide only along the second direction. The mounting groove 111 is a recessed groove formed by the inward indentation of the upper end of the limiting wall 110. The pivot of the locking block 610 is mounted on the two side walls of the mounting groove 111, so that most of the structure of the locking block 610 is located within the mounting groove 111, avoiding interference with other components. As an alternative embodiment, those skilled in the art can also set the limiting wall 110 as a detachable baffle structure, which is fixed to the housing 100 by bolts. The limiting sliding cavity formed by the limiting wall 110 further improves the stability of the sliding of the third slider 440 and the second slider 420, preventing them from shifting laterally and causing transmission jamming. The mounting groove 111 provides a dedicated mounting space for the locking block 610, making the layout of the locking mechanism 600 and the transmission mechanism 400 more compact, making full use of the internal space of the housing 100, and further reducing the overall volume of the operating mechanism.

[0052] Optionally, in some embodiments, the elastic member 640 is a compression spring, the mounting groove 111 is provided with a first elastic member limiting groove 112, and the bottom of the locking block 610 is provided with a second elastic member limiting groove 614, the two together forming a limiting cavity to accommodate the elastic member 640. As an alternative embodiment, a torsion spring can also be used.

[0053] Optionally, in some embodiments, the locking block 610 has a pushing portion 612 located on the side of the third slider 440 along the first direction, which is used to cooperate with the unlocking cam 620. When the locking block 610 is pushed away from the first slot 631 by the unlocking cam 620, the pushing portion 612 remains on the side of the third slider 440 along the first direction. Figure 10 As shown, the pushing part 612 is a protruding structure extending from the locking block 610, located on one side of the locking part 611. Its projection along the first direction covers the edge area of ​​the third slider 440 along the first direction. When the locking block 610 rotates about the pivot, the pushing part 612 is always located on the side of the third slider 440 along the first direction, and will not leave the limiting range of the third slider 440 along the first direction, ensuring engagement with the unlocking cam 620.

[0054] Optionally, in some embodiments, the first slider 410 has a mating groove 413 on the side near the third slider 440, and a second transmission gear 210 and a rack 414 extending in the second direction are provided in the mating groove 413. The second transmission gear 210 is sleeved on the drive shaft 200 and rotates synchronously with the drive shaft 200. The rack 414 meshes with the second transmission gear 210 and is linked to the first slider 410. Specifically, as shown... Figure 7 As shown, the mating groove 413 is a rectangular groove formed by recesses on the first slider 410. Its depth is sufficient to accommodate the second transmission gear 210 and the rack 414 without affecting the relative sliding between the first slider 410 and the third slider 440. The second transmission gear 210 is integrally formed on the drive shaft 200 and rotates synchronously with the drive shaft 200. The rack 414 is integrally formed and fixed on the inner wall of the mating groove 413, its length extending along the second direction, with its tooth surface facing the second transmission gear 210 and meshing with it. When the drive shaft 200 drives the second transmission gear 210 to rotate, the meshing transmission between the gear and the rack 414 converts the rotational motion into linear motion, driving the first slider 410 to slide along the second direction. Through the meshing transmission of the second transmission gear 210 and the rack 414, the smooth conversion of the rotational motion of the drive shaft 200 to the linear motion of the first slider 410 is realized, with high transmission efficiency and low noise. The setting of the groove 413 provides a dedicated installation space for the transmission gear and the rack, so that the transmission structure and the slider structure are compactly combined, further reducing the overall volume of the operating mechanism.

[0055] Alternatively, in some embodiments, such as Figure 12As shown, the output component 500 is pivotally supported between the housing 100 and the transmission mechanism 400, with its pivot axis positioned along a first direction. A protrusion 510, located a certain distance from its pivot axis and protruding towards the transmission mechanism 400, is provided on the side near the transmission mechanism 400. A drive groove 424 is provided on the second slider 420 for the protrusion 510 to be inserted, allowing it to slide linearly along a second direction and drive the output component 500 to rotate. The protrusion 510 is inserted into the drive groove 424 with a clearance fit, ensuring smooth sliding of the protrusion 510 within the drive groove 424. When the second slider 420 slides linearly along the second direction, the inner wall of the drive groove 424 pushes the protrusion 510, causing the output component 500 to rotate around its pivot axis, thereby driving the moving contact of the disconnecting switch to operate, achieving opening and closing of the circuit breaker. Specifically, a mounting plate 120 is fixed inside the housing 100, forming a lower space between the housing 100 and the mounting plate 120. The output component 500 is located in the lower space, and the transmission mechanism 400 is mounted above the mounting plate 120. The mounting plate 120 has an arc-shaped through hole for the protrusion 510 to pass through and move, making the overall structure compact. As an alternative embodiment, those skilled in the art can also set the protrusion 510 on the second slider 420 and the drive groove 424 on the output component 500, which can also realize the conversion from linear motion to rotary motion. Through the cooperation of the protrusion 510 and the drive groove 424, a simple and reliable conversion from the linear motion of the second slider 420 to the rotary motion of the output component 500 is achieved, without the need for complex transmission components, simplifying the structure and reducing costs; the clearance fit design ensures the smoothness of motion conversion and reduces the risk of jamming.

[0056] Optionally, in some embodiments, the output component 500 is a cam structure, and a tripping detection switch 710 and a closing detection switch 720 are fixed between the housing 100 and the transmission mechanism 400, respectively corresponding to the two extreme positions of the cam profile of the output component 500. Specifically, the cam profile of the output component 500 is designed according to the rotation angle and stroke required for tripping, and has two extreme protrusion positions, corresponding to the tripping and closing states, respectively. Both the tripping detection switch 710 and the closing detection switch 720 are microswitches in the prior art, fixed to the mounting plate 120 by bolts, with their trigger ends facing the cam profile of the output component 500. When the output component 500 rotates to the tripping extreme position, the corresponding protrusion of the cam profile triggers the tripping detection switch 710, sending a tripping signal; when it rotates to the closing extreme position, the other protrusion triggers the closing detection switch 720, sending a closing signal. The signal output ends of the detection switches can be connected to the control system to realize real-time monitoring and feedback of the tripping and closing states, especially for use with electric operating mechanisms. As an alternative embodiment, those skilled in the art can also use a proximity switch instead of a micro switch, and achieve position detection by detecting the sensing protrusion on the output component 500, thus avoiding mechanical contact wear.

[0057] Alternatively, in some embodiments, such as Figure 2 As shown, the housing 100 is provided with buffer pads 130 on both sides of the transmission mechanism 400 along its sliding direction. The buffer pads 130 are used to buffer the transmission mechanism 400 when it moves to its limit position, preventing direct impact on the housing 100. In particular, the second slider 420 moves under the drive of the energy storage spring 430. If the elasticity of the energy storage spring 430 is set too high, the impact force generated by the second slider 420 will be too large, potentially damaging the insulating plastic housing 100. Specifically, the buffer pads 130 can be directly fixed to the inner wall of the housing 100, or... Figure 14 As shown, it is fixed by a bracket that is fixedly connected to the housing 100.
