[0002] Currently, many new types of switches are designed to be applied in new scenarios. For example, a fusion switch can integrate the functions of a contactor and a disconnector. For this type of switch, it must have an electric opening and closing function. For safety reasons, this type of switch must also have a manual opening and closing function. At the same time, it is also hoped that this type of switch has a higher waterproof performance, such as a higher waterproof grade (such as IP65 or even IP67).

[0003] Generally speaking, when a switch is installed on a cabinet, a rotary handle is usually attached to the switch. The rotary handle is driven to perform opening and closing operations on the switch. However, it is difficult for existing switches with rotary handles to simultaneously achieve the above expectations, that is, to achieve automatic operation functions and manual operation functions while also ensuring high waterproof performance.

[0004] Therefore, it is hoped that there will be a technical solution that can at least solve the above-mentioned existing problems. Utility Model Content

[0070] The present invention will be described in detail below by describing exemplary embodiments.

[0071] Figure 1 FIG. 1 shows a three-dimensional diagram of an out-of-cabinet operating device 1 according to the present utility model. Figure 1In the embodiment, the external operation device 1 is configured to be installed on a cabinet panel 900, and a switch 80 is installed behind the cabinet panel 900. Therefore, the operator can manually operate the external operation device 1 from outside the cabinet, and then control the switch 80, such as switching the switch 80 between automatic and manual modes, operating the switch 80 in manual mode, and performing padlocking. The switch 80 and the external operation device 1 can be part of a switch assembly, and the switch assembly can be part of an electrical device, or the external operation device 1 itself can be part of an electrical device. Figure 1 As shown, the external cabinet operating device 1 includes a housing 10 , an adapter 20 arranged on the housing 10 , and a padlock assembly 60 .

[0072] Figure 2 A perspective view of the cabinet external operating device 1 according to the present invention is shown, wherein the main body of the housing 10 is not shown, but a second sealing ring 42 provided at the periphery of the housing 10 is shown. Specifically, the housing 10 is mounted on the cabinet board 900, for example, mounted on the through hole of the cabinet board 900 to face the switch 80. Thus, the housing 10 defines a housing inner side 102 facing the inner side of the cabinet, that is, facing the switch 80, and a housing outer side 101 facing the outer side of the cabinet, so that the housing outer side 101 and the housing inner side 102 face oppositely.

[0073] like Figure 2 As shown, the adapter 20 is arranged through the housing 10, and a first sealing ring 41 is arranged between the adapter 20 and the housing 10. Therefore, at least at the position of the adapter 20, the cabinet operating device 1 has good sealing performance. The adapter 20 has a receiving hole 230, which is open to the outside of the housing to receive, for example, the rod 510 of the handle 50.

[0074] Figure 2 The padlock assembly 60 is again shown, and includes a padlock plate 600. Although Figure 2 The main body of the housing 10 is hidden, but in the embodiment according to the present invention, the padlock piece 600 itself is arranged outside the housing 10. For example, the housing 10 may have a housing recess, and the padlock piece 600 is basically arranged in the recess, as described in detail below.

[0075] Figure 2 Also shown is a handle 50 placed on the housing 10 . The handle 50 can be detached from the housing 10 so that an operator or the like can hold the handle 50 to insert its rod portion 510 into the receiving hole 230 of the adapter 20 . Figure 2 A micro switch 30 is also shown, which serves as a mode conversion device 30 for the switch 80 and is configured to be triggered by a portion of the adapter 20 to switch the switch from the automatic mode to the manual mode, and to switch the switch to the automatic mode when the portion of the adapter 20 is removed, as described in detail below.

[0076] Figures 3A-3F 1 is a cross-sectional view of the out-of-cabinet operating device 1 according to the present invention, which passes through the longitudinal axis of the substantially cylindrical adapter 20 .

[0077] Specifically, if Figure 3A As shown, the housing 10 defines an outer housing side 101 and an inner housing side 102 facing opposite directions, and includes a first through hole 110 penetrating the outer housing side 101 and the inner housing side 102 , and a first direction 111 is defined from the outer housing side 101 toward the inner housing side 102 .

[0078] Also refer to Figure 2 , the adapter 20 includes a cylindrical adapter body 200, and the adapter body 200 is arranged through the first through hole 110. Thus, the adapter 20 can be manipulated to move between the adapter first position and the adapter second position along the first through hole 110 (for example, for switching between manual mode and automatic mode) and rotate relative to the first through hole 100 (for example, operating a switch in manual mode). Among them, the adapter first position is closer to the inner side 102 of the shell than the adapter second position. A first sealing ring 41 is arranged between the outer periphery of the adapter body 200 and the first through hole 110. For example, the first sealing ring 41 can be fixed on the outer periphery of the adapter body 200, and move with the movement of the adapter 20, while ensuring the seal between the outer periphery of the adapter body 200 and the inner wall of the first through hole 110.

[0079] like Figure 3A As shown, the adapter 20 includes a first operating portion 210 located on the inner side 102 of the housing. In the embodiment according to the present invention, the first operating portion 210 is a flange (at the Figures 3A-3F , the adapter body 200 includes the left half of the adapter 20 with sparse hatching lines and the right half of the adapter 20 with dense hatching lines). Wherein, when the adapter 20 is in the first adapter position, the first operating part 210 triggers the mode conversion device 30 (such as a micro switch 30) to switch the switch 80 to the manual mode, and when the adapter 20 is in the second adapter position, the first operating part 210 moves with the adapter 20 toward the outer side 101 of the housing and separates from the mode conversion device 30 to switch the switch 80 to the automatic mode. It should be noted that since the first operating part 210 is a flange extending radially outward around the cylinder (also refer to Figure 4 ), therefore, no matter what angle position the adapter 20 is in, the first operating portion 210 can trigger or leave the mode conversion device 30.

[0080] Figure 3AAlso shown is a second operating portion 220 of the adapter 20, which is a non-cylindrical column fixed to the adapter body 200 and extending from the adapter body 200 toward the inner side 102 of the housing. Thus, the rotation of the adapter 20 can drive the rotation of the second operating portion 220, and the second operating portion 220 can thus operate the switch 80, for example in the form of a spline fit. Also refer to Figure 4 , Figure 4 The second operating portion 220 is shown to be cylindrical, and its cross section perpendicular to the longitudinal axis is square.

[0081] Figure 3A A handle 50 is also shown ready for operating the adapter 20. The handle 50 includes a rod 510, which is configured to be inserted into a receiving hole 230 provided in the center of the adapter 20 to drive the movement of the adapter 20. The end of the handle 50 opposite to the rod 510 can be used for holding, and may also have a structure different from that shown in the drawings. According to an embodiment of the utility model, the main body of the rod 510 is a column with a square cross section, and the end of the rod 510 is provided with a driving flange 515, and the radial dimension of the driving flange 515 is greater than the radial dimension of the main body of the rod 510, for example, the driving flange 515 is a larger square, that is, has a square cross section. On the other hand, the cross section of the receiving hole 230 perpendicular to the longitudinal axis can be a square that matches the square shape of the driving flange 515, and the receiving hole 230 ends inside the adapter 20 to form a blind hole. Thus, when the rod 510 is partially located in the receiving hole 230 (the driving flange 515 is already located in the receiving hole 230), the rod 510 can move along the longitudinal axis of the receiving hole 230, and if the rod 510 is rotated by the operator, the driving flange 515 drives the adapter 20 to rotate. Of course, the main body of the rod 510, the driving flange 515 and the receiving hole 230 can have other corresponding non-circular shapes.

[0082] Further, if Figure 3A As shown, the cabinet operating device 1 includes a pin 250. The pin 250 is arranged in a pin through hole 240 extending radially from the receiving hole 230 to the outer periphery of the adapter body 200, and can move between a first pin position and a second pin position. Figure 3A ), the pin protrudes from the outer wall of the adapter body 200 but not from the inner wall of the receiving hole 230. In the second position of the pin (e.g. Figure 3C ), the pin protrudes from the inner wall of the receiving hole 230 but not from the outer wall of the adapter body 200.

[0083] Still see Figure 3A, the housing 10 is provided with a step portion 115 at the end of the first through hole 110 located on the outer side 101 of the housing. Thus, the step portion 115 includes a radial inner wall of the first through hole 110 at the end and a surface extending radially outward from the end. As will be described in detail below, the step portion 115 and the aforementioned drive flange 515 are configured to drive the pin 250 to move between the pin first position and the pin second position. At the same time, the end of the pin 250 configured to be able to protrude from the outer periphery of the adapter body 200 has an arc-shaped surface, and the end of the pin 250 configured to be able to protrude into the receiving hole 230 also has an arc-shaped surface, which enables the aforementioned drive to be achieved.

[0084] Next, refer to Figures 3A-3F , introducing the process of inserting the handle 50 into the receiving hole 230 and removing it from the receiving hole 230.

[0085] exist Figure 3A In the embodiment, the rod 510 of the handle 50 has not yet been inserted into the receiving hole 230 , the adapter 20 is in the second adapter position close to the outside of the shell, and the pin 250 is in the first pin position protruding from the periphery of the adapter body 200 .

[0086] exist Figure 3B In the embodiment, the rod 510 begins to be inserted into the receiving hole 230. Since the pin 250 is in the first pin position, the driving flange 515 moves through the pin through hole 240 without hindrance until it abuts against the end wall of the receiving hole 230. Afterwards, the movement of the rod 510 toward the inner side 102 of the housing can drive the adapter 20 to move toward the inner side 102 of the housing.

[0087] It should be noted that when the pin through hole 240 on the adapter 20 drives the pin 250 to move toward the inside of the housing, the end of the pin 250 protruding from the outer periphery of the adapter body 200 will contact the step portion 115. Due to the arc-shaped end shape of the pin 250, the step portion 115 applies a thrust to the pin 250 in the direction of the receiving hole 230 during the movement of the pin 250 toward the inside of the housing, thereby pushing the pin 250 from the first pin position to the second pin position.

[0088] After the pin 250 has reached the second pin position, the rod 510 can continue to push the adapter 20 toward the housing interior 102, and finally the adapter 20 reaches the first adapter position. At this time, the first operating portion 210 of the adapter 20 triggers the micro switch 30, thereby switching the switch 80 from the automatic mode to the manual mode.

[0089] like Figure 3DAs shown, the rod 510 begins to be pulled toward the outer side 101 of the housing, for example, when it is desired to switch from the manual mode to the automatic mode. When the rod 510 is first pulled, the rod 510 moves toward the outer side 101 of the housing relative to the receiving hole 230, and the adapter 20 itself does not move. When the driving flange 515 of the rod 510 contacts the pin 250, the driving flange 515 pushes the pin 250 and then pushes the adapter 20 to move toward the outer side 101 of the housing, so that the adapter 20 leaves the first adapter position.

[0090] like Figure 3E As shown, when the pin through hole 240 moves through the step portion 115, for example, when the vertex of the end of the pin 250 located at the outer periphery of the adapter body 200 passes through the step portion 115, the thrust of the drive flange 515 acting on the opposite end of the pin 250 can push the pin 250 to move radially outward. Thereafter, after the drive flange 515 continues to move a certain distance, the pin 250 is pushed to the first pin position. After that, there is only friction between the rod 510 and the receiving hole 230. When the rod 510 finally leaves the adapter 20 toward the outer side 101 of the shell, the adapter 20 can move a certain distance toward the outer side 101 of the shell due to the friction, as shown in FIG. Figure 3F shown.

[0091] In summary, through the components of the external cabinet operating device 1 according to the utility model, the switch between the manual mode and the automatic mode can be realized by inserting and removing the rod 510 of the handle 50 into and out of the receiving hole 230. Moreover, in the automatic mode, no component inside the switch 80 needs to contact and drive the adapter 20, so the first sealing ring 41 does not need to move, thereby extending its life and improving the sealing effect.

[0092] Figure 5A and Figure 5B The padlock assembly 60 of the external cabinet operating device 1 according to the present invention is shown respectively. The padlock assembly 60 is configured to padlock the external cabinet operating device 1 .

[0093] The padlock assembly 60 includes a padlock plate 600 and a locking rod 610 . Figure 5A and Figure 5B The main body of the housing is not shown. In practice, the padlock piece 600 is disposed on the outer side 101 of the housing. For example, the housing 10 may be provided with a recessed portion open to the outside to arrange the padlock piece 600. In practice, the lock rod 610 passes through the second through hole 120 of the housing 10 (the position is only shown by an arrow) and is disposed between the padlock piece 600 and the switch 80. The lock rod 610 can move along the second through hole 120 to drive the padlock piece 600 to move. At the same time, a third sealing ring 43 is disposed between the lock rod 610 and the second through hole 120 to further improve the sealing of the external cabinet operating device 1. For example, the third sealing ring 43 may be circumferentially fixed on the lock rod 610.

[0094] like Figure 5A As shown, the padlock plate 600 has opposite first and second ends 601 and 602 and is rotatable about a rotation axis 603 located between the first and second ends 601 and 602 (e.g., via an axis fixed to the housing 10 at the rotation axis 603). The first end 611 of the locking bar 610 is attached to the first end 601 of the padlock plate 600, for example, via a limited length slide mechanism. The second end 602 of the padlock plate 600 may have one or more padlock holes 605. Thus, when the locking bar 610 is in the first locking bar position ( Figure 5B ) and the second position of the lock lever ( Figure 5A ) can drive the padlock piece 600 around the rotation axis 603 to move between the padlock piece first position ( Figure 5B ) and padlock second position ( Figure 5A ) and since the padlock piece 600 is disposed in a corresponding recess of the housing 10, in the first position ( Figure 5B ), the padlock hole 605 is exposed (for example, the second end 602 protrudes from the surface of the housing 10) so as to be padlockable, and in the second position ( Figure 5A ), the padlock hole 605 is hidden (for example, the second end 602 moves into the recessed portion of the housing 10, and the padlock hole 602 is blocked by the structure of the housing 10).

[0095] In addition, if Figure 5A and Figure 5B As shown, the switch 80 may include a gear 810, and the gear 810 includes a recess 811. The second end 612 of the locking rod 610 opposite to the first end 611 is arranged near the gear 810, so that in the open state of the switch, the gear 810 rotates to the first gear position ( Figure 5B ), at this time, the second end 612 of the locking rod 610 can extend into the recess 811 of the gear 810 to reach the first position of the locking rod. When the switch is closed, the gear 810 rotates to the second position of the gear ( Figure 5A ), at this time, the second end 612 of the locking rod 610 cannot extend into the recess 811 and is located at the second locking rod position. Therefore, the padlock can only be performed when the switch 80 is in the open state.
