[0035] As described above, the terminal of the conventional electrical switch has no torque-to-grip prompt during the process of the operator screwing the terminal, so that the operator cannot know whether the rated torque is reached. Embodiments of the present disclosure provide an electrical switch 100 to at least partially solve the above problem. In the following, the electrical switch 100 will be described in detail with reference to the drawings. Figures 1 to 6 The principles of the present disclosure are described.

[0036] Figure 1 A partial structural schematic diagram of the electrical switch 100 according to some embodiments of the present disclosure is shown. Figure 2 A structural schematic diagram of the terminal 3, the driving member 4, and the elastic member 6 according to some embodiments of the present disclosure is shown. Figure 3 An exploded view of the terminal 3, the driving member 4, and the elastic member 6 is shown. As shown in the exploded view, the terminal 3, the driving member 4, and the elastic member 6 are arranged in the shell 1. Figure 2 An exploded view of the terminal 3, the driving member 4, and the elastic member 6 is shown. As shown in the exploded view, the terminal 3, the driving member 4, and the elastic member 6 are arranged in the shell 1. Figures 1 to 3 As shown, the electrical switch 100 described herein generally includes a shell 1, a moving member 2, a terminal 3, a driving member 4, and an elastic member 6. The moving member 2, the terminal 3, the driving member 4, and the elastic member 6 are respectively located in the shell 1.

[0037] Reference will be made to the drawings to more fully explain the above-described embodiments of the present disclosure. It should be noted that the drawings are not necessarily drawn to scale and that the embodiments can be used as built-in components, separate components, or combinations thereof. Figures 1 to 3In some embodiments, the connecting piece 3 can be connected with the moving piece 2 and include a matching groove 31 arranged on the side of the connecting piece 3 facing away from the moving piece 2. The driving piece 4 surrounds the side of the connecting piece 3 facing away from the moving piece 2 and can be screwed, and the driving piece 4 includes a matching part 41 arranged in the matching groove 31 and can be matched with the matching groove 31. Thus, in the case that the driving piece 4 is screwed, the torque applied to the driving piece 4 can be transmitted to the connecting piece 3 to drive the connecting piece 3 to rotate relative to the housing 1 with the driving piece 4. Since the connecting piece 3 is limited by the housing 1 and cannot move, and the connecting piece 3 is engaged with the moving piece 2 through threads, in the case that the connecting piece 3 rotates, the connecting piece 3 can drive the moving piece 2 to move towards the driving piece 4 to drive the wires or cables to move and be pressed on the terminal.

[0038] Figure 4 A structural schematic diagram of the driving piece 4 according to some embodiments of the present disclosure is shown. As shown, in some embodiments, the elastic piece 6 is located between the housing 1 and the side of the driving piece 4 facing away from the moving piece 2 and is in a compressed state to press the driving piece 4 on the connecting piece 3. The matching part 41 includes at least one driving slope 5. In the case that the driving piece 4 is screwed, the matching part 41 can be rotated to a position where the at least one driving slope 5 of the matching part 41 abuts against the inner surface of the matching groove 31, and the matching groove 31 can apply a force to the at least one driving slope 5, and the component of the force in the direction X of the driving piece 4 pointing to the moving piece 2 can drive the driving piece 4 to move away from the moving piece 2. Figures 1 to 4

[0039] It can be understood that before the torque applied to the connecting piece 3 reaches the rated torque, that is, before the connecting piece 3 is tightened, the component of the force is smaller than the elastic force of the elastic piece 6 on the driving piece 4, so that the driving piece 4 can be pressed on the connecting piece 3 and drive the connecting piece 3 to rotate through the matching relationship between the matching part 41 and the matching groove 31. However, when the torque applied to the connecting piece 3 reaches the rated torque, that is, when the connecting piece 3 is tightened, if the driving piece 4 is continued to be screwed, the driving piece 4 will no longer drive the connecting piece 3 to rotate, at this time the component of the force can drive the driving piece 4 to move away from the moving piece 2 and compress the elastic piece 6, and in the process of movement, the matching part 41 can be disengaged from the matching groove 31 to make the driving piece 4 and the connecting piece 3 decouple. Obviously, the distance that the component of the force compresses the elastic piece 6 should be greater than or equal to the height of the matching part 41 in the matching groove 31 to ensure that the driving piece 4 can be disengaged.

[0040] ​According to the embodiment of the present disclosure, at least one driving slope 5 of the fitting part 41 can be turned to a position abutting against the inner surface of the fitting groove 31 during the process of screwing the driving member 4, so that the fitting groove 31 can apply a force to the at least one driving slope 5. When the torque applied to the wiring member 3 reaches the rated torque, the force can drive the driving member 4 to move away from the moving member 2 and press the elastic member 6 to be disconnected from the wiring member 3. Thus, the sound produced during disconnection and the change in hand feeling can prompt the operator that the rated torque has been reached to prevent over-torque.

[0041] In addition, the electrical switch 100 of the embodiment of the present disclosure can achieve the effect of torque indication by adding the driving member 4 and the elastic member 6 at each pole, and the modification of the electrical switch 100 is small, effectively reducing the material cost and improving the installation efficiency. In addition, since the position of the wiring member 3 in the direction X in which the driving member 4 points to the moving member 2 is unchanged, the accuracy of the torque indication is improved.

[0042] Referring back to Figure 1 In some embodiments, the housing 1 can further include at least one indication hole 12, and the driving member 4 can be located at the at least one indication hole 12. Thus, the operator can observe the process of the driving member 4 being disconnected from the wiring member 3 through the at least one indication hole 12 to prompt the operator that the rated torque has been reached. Further, to increase the prompting effect, the driving member 4 can include an indication part, such as a color mark or a symbol mark, adjacent to the at least one indication hole 12. Thus, the operator can observe the change of the indication part through the at least one indication hole 12 to prompt the operator that the rated torque has been reached.

[0043] It should be noted that the numbers, values, numbers mentioned above and possibly mentioned elsewhere in the present disclosure are exemplary and are not intended to limit the scope of the present disclosure in any way. Any other appropriate numbers, values, numbers are possible. For example, according to the specific application scenario and requirements, the at least one indication hole 12 can include a pair of indication holes 12.

[0044] Referring back to Figure 2 and Figure 3 The wiring member 3 can include a head 32 and a rod body 33 connected to the head 32. The fitting groove 31 can be provided on the head 32, and the driving member 4 can be provided around the side of the head 32 away from the moving member 2. Referring back to Figures 2 to 4The driving member 4 may include a main body 42, and a mating part 41 is disposed on the main body 42. The main body 42 may include a receiving groove 421 adjacent to the moving member 2, and the mating part 41 may be located within the receiving groove 421. The head 32 is located within the receiving groove 421, and the outer side surface of the head 32 and the end face of the head 32 facing away from the moving member 2 respectively abut against the inner surface of the receiving groove 421. Thus, the mating part 41 may be located within the mating groove 31 so that the wiring member 3 mates with the driving member 4.

[0045] Figure 5 A cross-sectional view of the wiring member 3 and the drive member 4, according to some embodiments of the present disclosure, is shown along a section. Figure 6 It shows Figure 5 The diagram shows a cross-sectional view of the connector 3 and drive unit 4 taken along another section. (See diagram below.) Figures 3 to 6 As shown, in some embodiments, the mating groove 31 may include a first groove 311 and a second groove 312, which may be connected and vertically arranged along the radial direction of the rod 33. Correspondingly, the mating part 41 may include a first part 411 and a second part 412, which may be connected and vertically arranged along the radial direction. The first part 411 may be located within the first groove 311, and the second part 412 may be located within the second groove 312.

[0046] With the above configuration, when the torque applied to the connector 3 during the tightening of the drive member 4 reaches the rated torque, the force can drive the drive member 4 to move away from the moving member 2 to disengage from the connector 3. After the drive member 4 rotates 90°, the mating part 41 can fall back into the mating groove 31, and the drive member 4 can continue to disengage from the connector 3, forming a reciprocating jumping process, which helps to increase the reminder effect.

[0047] It should be understood that in other embodiments, the mating part 41 and the mating groove 31 can be assembled using any other suitable structure, and this disclosure is not limited thereto. For example, in some other embodiments, the mating groove 31 may only include a first groove body 311, which may be arranged along the radial direction of the rod body 33. Correspondingly, the mating part 41 may only include a first portion 411, which may be arranged along the radial direction. The first portion 411 may be located within the first groove body 311. Thus, after the screw drive 4 rotates 180°, the mating part 41 can fall back into the mating groove 31, and the drive 4 can continue to disengage from the connector 3 to form a reciprocating jumping process to enhance the prompting effect.

[0048] Hereinafter, the electrical switch 100 of the present disclosure will be exemplarily described mainly in the case that the mating groove 31 comprises the vertically arranged first groove body 311 and the second groove body 312, and the mating part 41 comprises the vertically arranged first part 411 and the second part 412. Similar to the above-mentioned other cases, the present disclosure will not be described here again.

[0049] With reference to Figures 3 to 6 In some embodiments, the at least one driving slope 5 can comprise a first slope 51, a second slope 52, a third slope 53 and a fourth slope 54. The first slope 51 can be located on one side of the first part 411, and the second slope 52 can be located on the opposite side of the first part 411. The third slope 53 can be located on one side of the second part 412 and connected with the first slope 51 and the second slope 52 respectively. The fourth slope 54 can be located on the opposite side of the second part 412 and connected with the first slope 51 and the second slope 52 respectively. Thus, in the case that the driving member 4 is screwed, the mating groove 31 can abut against the first slope 51, the second slope 52, the third slope 53 and the fourth slope 54, and since the four contact positions of the mating groove 31 and the driving member 4 are uniformly distributed, the wiring member 3 rotates more smoothly in the process of being driven by the driving member 4, and the driving member 4 can also smoothly disengage from the wiring member 3 to avoid the problem of being stuck. In addition, the force acting on multiple parts can share the force acting on a single part, thereby greatly reducing the force acting on a single part, so as to avoid the breakage of the mating part 41 and improve the service life of the product.

[0050] With reference to Figures 3 to 6 In some embodiments, the distance between the first slope 51 and the second slope 52 gradually decreases along the direction X of the driving member 4 pointing to the moving member 2, and the distance between the third slope 53 and the fourth slope 54 gradually decreases. Thus, in the case that the driving member 4 is screwed, each slope can abut against the inner surface of the mating groove 31, the mating groove 31 can apply a oblique force to each slope, and the component of the oblique force in the direction X of the driving member 4 pointing to the moving member 2 can drive the driving member 4 to move away from the moving member 2, so that the driving member 4 can be disengaged from the wiring member 3.

[0051] In order to enable the at least one driving slope 5 of the mating part 41 to abut against the inner surface of the mating groove 31, with reference to Figures 3 to 6In some embodiments, the distance between the portion of the first inclined surface 51 facing away from the moving member 2 and the portion of the second inclined surface 52 facing away from the moving member 2 is smaller than the width of the first groove body 311, and the distance between the portion of the third inclined surface 53 facing away from the moving member 2 and the portion of the fourth inclined surface 54 facing away from the moving member 2 is smaller than the width of the second groove body 312, in the case where the outer side surface of the head 32 and the end surface of the head 32 facing away from the moving member 2 respectively abut against the inner surface of the accommodation groove 421. Thus, as shown in the example, Figure 5 the fitting portion 41 is located within the fitting groove 31 and spaced apart from the fitting groove 31, and the fitting portion 41 first rotates within the fitting groove 31 to a position in contact with the fitting groove 31 and then interacts with the fitting groove 31 during the process of the driving member 4 being screwed.

[0052] It should be understood that, in other embodiments, the fitting portion 41 and the fitting groove 31 can be assembled in any other suitable connection manner to enable at least one driving inclined surface 5 of the fitting portion 41 to abut against the inner surface of the fitting groove 31. For example, in some other embodiments, the distance between the portion of the first inclined surface 51 facing away from the moving member 2 and the portion of the second inclined surface 52 facing away from the moving member 2 is greater than the width of the first groove body 311, and the distance between the portion of the third inclined surface 53 facing away from the moving member 2 and the portion of the fourth inclined surface 54 facing away from the moving member 2 is greater than the width of the second groove body 312. That is, a portion of the fitting portion 41 is located within the fitting groove 31. Thus, the fitting portion 41 can interact with the fitting groove 31 at the same time as the driving member 4 is just being screwed.

[0053] It should be noted that, in the case of the driving member 4 being screwed at a certain torque, the force acting on each of the four inclined surfaces is uniform. The component of the force acting on each inclined surface in the direction X of the driving member 4 pointing towards the moving member 2 can be calculated according to the inclination angle of each inclined surface, and the magnitude and direction of the component of the force acting on each inclined surface should also be the same. The magnitude of the upward force provided by the fitting groove 31 to the fitting portion 41 is the sum of the four components, and thus the elastic force provided by the elastic member 6 when the connecting member 3 is rotated until the rated torque is reached should not be less than the sum of the four components. In the case of the amount of compression of the elastic member 6 being known, the stiffness coefficient of the elastic member 6 should not be less than the ratio of the sum of the four components to the amount of compression. It can be understood that the stiffness coefficient and the length of the elastic member 6 can be selected according to the magnitude of the torque, and the torque conversion capability can be changed by changing the inclination angle of each inclined surface, so as to select the stiffness coefficient of the elastic member 6. For example, referring to Figure 4 , the angle between each of the first inclined surface 51, the second inclined surface 52, the third inclined surface 53 and the fourth inclined surface 54 and the bottom surface of the accommodation groove 421 can be 93° to 100° to satisfy the manufacturability of the elastic member 6.

[0054] Referring back to Figure 3 andFigure 4 In some embodiments, the end of the main body 42 facing away from the moving part 2 is provided with an operation slot 422 and an annular slot 423. One end of the elastic part 6 is arranged in the annular slot 423. The annular slot 423 can be located outside the operation slot 422 to avoid interference of the elastic part 6 with a tool during screwing of the driving part 4. The annular slot 423 can be in communication with the operation slot 422, and of course the annular slot 423 can also be spaced apart from the operation slot 422, which is not limited herein.

[0055] Further, the operator can exert axial pressure during screwing, and if the elastic part 6 has a too low rigidity coefficient, it is easily affected by the axial pressure, so that the driving part 4 cannot be popped up. Although a too high rigidity coefficient of the elastic part 6 can ignore the influence of the axial pressure, it is difficult to select the material. To solve the above problems, the driving part 4 can include a hexagonal flat head nut. That is, the operation slot 422 is hexagonal. The hexagonal flat head nut can better transmit torque and reduce the possibility of the operator exerting axial force.

[0056] In addition, in order to avoid conduction between the wiring part 3 and the elastic part 6 to meet the insulation requirement, the driving part 4 can be made of an insulating material. For example, PPS (polyphenylene sulfide) or PPA (polyphthalamide) and the like. The driving part 4 made of PPS or PPA not only has good mechanical strength and rigidity, but also can withstand a large load to ensure the stability and reliability of the driving part 4; in addition, the PPS or PPA material has excellent electrical insulation performance.

[0057] Referring back to Figure 1 and Figure 3 In some embodiments, the housing 1 can also include an operation hole 11. The operation slot 422 can be located at the operation hole 11, so that the tool can extend into the operation slot 422 through the operation hole 11, facilitating screwing of the driving part 4. The other end of the elastic part 6 is connected to the part of the housing 1 adjacent to the operation hole 11, so that one end of the elastic part 6 is limited by the driving part 4 and the other end is limited by the housing 1.

[0058] The torque indication design according to the embodiments of the present disclosure can be applied to various electrical switches to at least partially solve the above problems. It should be understood that the torque indication design according to the embodiments of the present disclosure can also be applied to other electrical components, and the embodiments of the present disclosure do not limit this.

[0059] Having described above several embodiments of the disclosure, any modifications and variations that fall within the scope of the described embodiments are also contemplated. It is also contemplated that the application covered by the claims extends to any alternative embodiment, adaptations, or variations of the various embodiments described above, and to any and all equivalents.
