Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a flashlight switching component. Background Technology

[0002] Both circuit breakers and three-position disconnect switches are equipped with manual switching components. Taking the circuit breaker as an example, a microswitch is installed on the side of the corresponding grounding operating shaft and closing operating shaft on the frame, respectively. A transmission component is installed between the grounding operating shaft and the closing operating shaft and the corresponding microswitch. This transmission component consists of at least a moving rod and a spring. When the handle is inserted into the grounding operating shaft or the closing operating shaft, the handle pushes the moving rod, compresses the spring, and simultaneously causes the drive plate on the microswitch to press down the switch (button). The microswitch provides a manual operation signal, and the electric operating mechanism is de-energized. When the handle is pulled out and disengaged from the grounding operating shaft or the closing operating shaft, the spring releases energy, pushes the moving rod back to its original position, and the microswitch provides an electric operation signal, energizing the electric operating mechanism. In this structure, since the transmission component requires at least 2 to 3 parts, it is not only costly in mass production but also time-consuming to assemble. Therefore, it is necessary to improve this structure. Utility Model Content

[0003] The purpose of this invention is to provide a flashlight switching component. This invention has a simpler structure and fewer parts, which can significantly reduce production costs and assembly time, and bring good economic benefits to enterprises.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flashlight switching assembly, installed on the side of the operating shaft of a mechanism, used to disconnect the electrical connection of the electric operating mechanism when the handle is inserted; it includes a bracket and a micro switch, the bracket being connected to the frame of the mechanism, the micro switch being installed on the bracket, the micro switch including a housing, a drive plate disposed outside the housing, and a switch element passing through the side of the housing for cooperating with the drive plate, the drive plate having a guide plate at the end away from the housing, the guide plate being inclined, and the plane of the guide plate forming an acute angle with the insertion direction of the handle.

[0005] By adopting the above technical solution, a set of manual switching components is set on the side of the operating shafts (grounding operating shaft and closing operating shaft) of the mechanism. When the handle is inserted into the manual operating shaft, the handle first pushes the guide plate on the micro switch (the inner end of the handle cooperates with the inclined plane of the guide plate), causing the drive plate to press down the switch. The micro switch provides an electric operating signal, the electric operating mechanism is de-energized, and the operating shaft can be manually operated by inserting the handle again. When the handle is pulled out, the micro switch resets, and the electric operating mechanism is energized. This eliminates at least 2 to 3 parts of the original transmission assembly. By using the micro switch's own structure in conjunction with the handle, the structure is simpler, with fewer parts, which can significantly reduce production costs and assembly time, bringing good economic benefits to enterprises.

[0006] The present invention is further configured such that the guide plate and the drive plate are an integral structure.

[0007] By adopting the above technical solution, the guide plate is made by bending the drive plate, which is convenient to process and has high structural strength.

[0008] The present invention is further configured such that the drive plate includes a T-shaped connecting part, a first straight extension section, an inclined buffer section and a second straight extension section connected in sequence, the T-shaped connecting part is connected to the outer shell, the first straight extension section, the inclined buffer section and the second straight extension section are disposed at the outer end of the T-shaped connecting part, and the guide plate is disposed on the side of the second straight extension section.

[0009] By adopting the above technical solution, an inclined buffer section is set between the first linear extension section and the second linear extension section to relieve stress. This can prevent stress concentration at the connection between the drive plate and the housing when the handle is in use, thereby improving the service life of the micro switch.

[0010] The present invention is further configured such that the bracket is provided with a protective stop for limiting the insertion of the handle, and the end of the protective stop is located in front of the end of the guide plate away from the drive plate.

[0011] By adopting the above technical solution, since the drive board of the micro switch is very fragile, when the insertion direction of the handle is deviated by a large amount, the protective block can limit the handle, preventing it from being pushed against the guide plate. This avoids the handle directly pushing the end of the guide plate in the forward direction, causing the guide plate to lose its guiding function and causing the drive board to bend and be damaged.

[0012] The present invention is further configured such that the bracket includes a connecting base plate, a height extension plate and a mounting plate in an integral structure, the mounting plate is arranged parallel to the connecting base plate, the connecting base plate is connected to the frame by screws, and the housing of the micro switch is connected to the mounting plate by screws.

[0013] By adopting the above technical solution, the bracket has a simple and reliable structure, and it is easy to accurately install the micro switch.

[0014] The present invention is further configured such that the protective block is L-shaped and is formed by bending a mounting plate.

[0015] By adopting the above technical solution, its structure is simple and reliable, easy to process, and has high strength.

[0016] The present invention is further provided that an insulating partition is sandwiched between the housing of the micro switch and the mounting plate.

[0017] By adopting the above technical solution, the micro switch can be prevented from being accidentally electrically connected due to the influence of other electrical appliances, thus avoiding safety accidents. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: As attached Figures 1-4The flashlight switching assembly shown is installed on the side of the operating shaft 2 of the mechanism and is used to disconnect the electrical connection of the electric operating mechanism when the handle is inserted. It includes a bracket 4 and a micro switch 5. The bracket 4 is connected to the frame 1 of the mechanism, and the micro switch 5 is installed on the bracket 4. The micro switch 5 includes a housing 6, a drive plate 7 disposed outside the housing 6, and a switch element 8 passing through the side of the housing 6 for cooperating with the drive plate 7. The drive plate 7 has a guide plate 9 at the end away from the housing 6. The guide plate 9 is inclined and the plane of the guide plate 9 forms an acute angle with the insertion direction of the handle (that is, a conical surface with a smaller inner diameter and a larger outer diameter). A set of manual switching components is installed on the side of the operating shaft 2 (grounding operating shaft and closing operating shaft) of the mechanism. When the handle is inserted into the manual operating shaft 2, the handle first pushes the guide plate 9 on the micro switch 5 (the inner end of the handle is in contact with the inclined plane of the guide plate 9), causing the drive plate 7 to press down the switch 8. The micro switch 5 provides an electric operating signal, the electric operating mechanism is de-energized, and the operating shaft 2 can be manually operated by inserting the handle again. When the handle is pulled out, the micro switch 5 resets, and the electric operating mechanism is energized. This eliminates at least 2 to 3 parts of the original transmission assembly. By using the micro switch 5's own structure in conjunction with the handle, the structure is simpler, with fewer parts, which can significantly reduce production costs and assembly time, bringing good economic benefits to enterprises.

[0025] The guide plate 9 and the drive plate 7 are an integral structure. That is, the guide plate 9 is formed by bending the drive plate 7, which is convenient to process and has high structural strength.

[0026] As attached Figure 2 and attached Figure 3 As shown, the drive plate 7 includes a T-shaped connecting portion 10, a first straight extension section 11, an inclined buffer section 12, and a second straight extension section 13 connected in sequence. The T-shaped connecting portion 10 is connected to the housing 6, and the two can be plugged into each other. The first straight extension section 11, the inclined buffer section 12, and the second straight extension section 13 are disposed at the outer end of the T-shaped connecting portion 10. The center lines of the first straight extension section 11 and the second straight extension section 13 are parallel to each other. The guide plate 9 is disposed on the side of the second straight extension section 13. The first straight extension section 11, the inclined buffer section 12, and the second straight extension section 13 are on the same plane. The above structure is one embodiment of the drive plate and is not limited to this one embodiment. The inclined buffer section 12 is provided between the first straight extension section 11 and the second straight extension section 13 to relieve stress and prevent stress concentration at the connection between the drive plate 7 and the housing 6 when the handle is turned, thereby improving the service life of the micro switch 5.

[0027] As attached Figure 2 and attached Figure 4As shown, the bracket 4 is provided with a protective stop 14 to limit the insertion of the handle. The end of the protective stop 14 is located directly in front of the end of the guide plate 9 away from the drive plate 7. Since the drive plate 7 of the micro switch 5 is very fragile, if the insertion direction of the handle is significantly deviated, the protective stop 14 can limit the handle, preventing it from pushing against the guide plate 9. This avoids the handle directly pushing against the end of the guide plate 9, causing the guide plate 9 to lose its guiding function and causing the drive plate 7 to bend and be damaged.

[0028] As attached Figure 4 As shown, the bracket 4 includes a one-piece connecting base plate 15, a height extension plate 16, and a mounting plate 17. The mounting plate 17 is arranged parallel to the connecting base plate 15. The connecting base plate 15 is connected to the frame 1 by screws. The housing 6 of the micro switch 5 is connected to the mounting plate 17 by screws. The bracket 4 has a simple and reliable structure and facilitates the accurate installation of the micro switch 5.

[0029] The protective stop 14 is L-shaped and is formed by bending the mounting plate 17. Alternatively, the protective stop 14 can be C-shaped or inclined, as long as it can block the deflected handle. Its structure is simple and reliable, easy to manufacture, and has high strength.

[0030] As attached Figure 2 As shown, an insulating partition 18 is sandwiched between the housing 6 and the mounting plate 17 of the micro switch 5. This design prevents the micro switch 5 from being accidentally electrically connected due to interference from other electrical appliances, thus avoiding safety accidents.
