Embodiment
[0037] As Figures 1-13 shown, an embodiment of the present utility model is a rotary disconnect switch, and this disconnect switch has an indicating structure. This rotary disconnect switch includes an operating unit layer 100 and a switch unit layer 200. The switch unit layer 200 is located below the operating unit layer 100 and is stacked in sequence along the first direction S1. Here, the first direction S1 can also be understood as the height direction of the product. The operating unit layer 100 is located at the topmost, and the remaining switch unit layers 200 are stacked below it in sequence. The operating unit layer 100 has an operating mechanism, and the switch unit layer 200 has a moving contact disc 300 and static contacts. By operating the operating mechanism, the rotation of the moving contact disc 300 can be realized, so as to realize the connection and disconnection of the switch unit layer 200. The moving contact discs 300 between adjacent two layers are in driving connection by means of insertion.
[0038] On the side walls 201d of the housing 201 of all the switch unit layers 200, four first mounting bosses 2010 are provided. Four second mounting bosses 1010 are provided on the outer shell of the operation unit layer 100. The first mounting bosses 2010 and the second mounting bosses 1010 here are in a one-to-one correspondence relationship, and each first mounting boss 2010 and the second mounting boss 1010 are fastened by a set of first fastening components B1.
[0039] There are many ways of the first fastening component B1 here.
[0040] As one of the ways, as Figure 3 shown, the first fastening component B1 is a bolt B10 and a nut B20. Here, the nut B20 is placed on the second mounting boss 1010, and then the bolt B10 passes through all the first mounting bosses 2010, the second mounting bosses 1010 and the nut B20 for fastening. Of course, the nut B20 in this way can also be placed on the first mounting boss 2010 of the last layer, and then the passing direction of the bolt B10 can be changed adaptively.
[0041] As another way, as Figure 4 shown, the first fastening components B1 are all two screws B30 and a fixing rod B40. Screw holes are opened at both ends of the fixing rod B40. The fixing rod B40 is passed through all the first mounting bosses 2010 and the second mounting bosses 1010, and the screws B30 are fastened at both ends of the fixing rod B40.
[0042] The above-mentioned first mounting bosses 2010 and second mounting bosses 1010 are not limited to the form of four, and can also be set to 3 or more than 4.
[0043] The specific indication structure of the disconnecting switch is as follows:
[0044] A groove 201a is opened at the bottom 201c of the last switch unit layer 200, and an exposed hole 201b is opened at the bottom of the groove 201a, so that at least a part of the moving contact disc 300 of the last switch unit layer 200 is exposed. Here, the size of the groove 201a is larger than the size of the exposed hole 201b.
[0045] The size of the transparent shielding member 400 is adapted to the size of the groove 201a. The transparent shielding member 400 can completely shield the exposed hole 201b, so as to prevent the electric arc from spraying out of the exposed hole 201b. The material of the transparent shielding member 400 here is selected as an insulating material, such as plastic, etc.
[0046] A second mark BS1 is provided on the moving contact disc 300, and the second mark BS1 is also exposed in the exposed hole 201b.
[0047] There is also a first identifier BS2 around the exposed hole 201b. There are many positions where the first identifier BS2 is set. For example, as Figure 6 shown, it can be set on the bottom of the groove 201a. For example, as Figure 8 shown, it can also be set on the transparent shielding member 400.
[0048] Since one of the first identifier BS1 and the second identifier BS2 is an indication identifier and the other is a status identifier, the indication identifier indicates the corresponding status identifier by the rotation of the moving contact disk 300, thereby realizing status indication.
[0049] Here, the icon of the indication identifier can be patterns such as arrows, pointers, gestures, etc. There are also many ways to form it. For example, through pad printing, laser marking, stickers, groove structures formed on corresponding components, convex structures formed on corresponding components, and other forms.
[0050] Here, the status identifier includes a closing status identifier and a tripping status identifier. There is an angular difference between the closing status identifier and the tripping status identifier in the circumferential direction. This angular difference means that the moving contact disk 300 rotates a certain angle from the position indicating the closing status to reach the position of the tripping status identifier, and vice versa. This angular difference is actually consistent with the angle of switch connection and disconnection, so that the status indication can truly reflect the connection and disconnection of the switch. There are many choices for this angular difference. In this embodiment, 90° is adopted. In addition, it can also be 60°, 120°, etc., as long as it is between 60° - 120°.
[0051] Here, whether it is the closing status identifier or the tripping status identifier, its icon can be words, letters, patterns, etc. For example, "open" and "close", "ON" and "OFF", "o" and "-", etc., as long as one can represent connection and the other can represent disconnection. For the formation of the closing status identifier and the tripping status identifier, it can be through forms such as pad printing, laser marking, stickers, groove structures formed on corresponding components, convex structures formed on corresponding components, and other forms.
[0052] Here, the first identifier BS2 is the status identifier and the second identifier BS1 is the indication identifier. The first identifier BS2 is set on the bottom of the groove. Here, in addition to the bottom of the groove, it can also be set on the transparent shielding member 400.
[0053] The moving contact disc 300 has a first boss 301a. The first boss 301a penetrates into the exposed hole 201b. The first boss 301a is rotatably arranged relative to the exposed hole 201b. Here, the second identifier BS1 is arranged in the recess 301b of the first boss 301a. Here, in addition to adopting such a method, the first boss 301a can also penetrate into the exposed hole 201b (without exceeding the exposed hole 201b). Similarly, the first boss 301a can also be not provided with the recess 301b, and the second identifier BS1 can be directly arranged on the first boss 301a. Here, there are many choices for the shape of the exposed hole 201b, such as hexagon, polygon, triangle, etc. It only needs to have a large gap between the first boss 301a and its wall, without hindering the normal movement of the moving contact disc 300, and can achieve normal indication. As a relatively preferred method, the shape of the exposed hole 201b is circular, that is, the cross-sectional shape of the exposed hole 201b is circular, and the outer peripheral wall of the cross-sectional shape of the first boss 301a is also circular. In this way, the first boss 301a can rotate along the hole wall of the exposed hole 201b, which is beneficial to the rotational arrangement of the moving contact disc 300.
[0054] Regardless of which form it is, the transparent shielding member 400 covers both the first identifier BS1 and the second identifier BS2. Even for the case where the first identifier BS2 is arranged on the transparent shielding member 400, it is also covered by the transparent shielding member 400.
[0055] For the fixing method of the transparent shielding member 400, there are many setting forms, such as screw fastening, snap fixing, welding fixing (ultrasonic welding), bonding fixing and so on.
[0056] The following introduces several specific fixing methods of the transparent shielding member 400:
[0057] Such as Figure 9As shown, the transparent shielding member 400 is fastened by screws BT1. In this embodiment, the housing 201 of the last layer of switch unit layer 200 includes two side walls 201d, and these two side walls 201d are opposite to each other (two diametrically opposite side walls 201d). Here, the groove 201a includes an indication covering area 201a1 and two communication areas 201a2. Both sides of the indication covering area 201a1 are respectively connected to the side wall 201d through a communication area 201a2. The transparent shielding member 400 includes an indication shielding portion 401 and two side branches 402. The indication shielding portion 401 fills the indication covering area 201a1, and the side branches 402 fill the corresponding communication areas 201a2. The end portions of the two side branches 402 respectively extend to the corresponding side walls 201d, and then the end portions are fastened to the side walls 201d by screws BT1. Of course, in this way, when the wall thickness permits, the two side branches 402 can also be directly fastened to the bottom 201c of the housing 201 by screws BT1.
[0058] As Figures 6-7 , as shown in FIG. 10, the transparent shielding member 400 is fastened by a snap connection. In this embodiment, the housing 201 of the last layer of switch unit layer 200 includes two side walls 201d, and these two side walls 201d are opposite to each other (two diametrically opposite side walls 201d). Here, the groove 201a includes an indication covering area 201a1 and two communication areas 201a2. Both sides of the indication covering area 201a1 are respectively connected to the side wall 201d through a communication area 201a2. The transparent shielding member 400 includes an indication shielding portion 401 and two side branches 402. The indication shielding portion 401 fills the indication covering area 201a1, and the side branches 402 fill the corresponding communication areas 201a2. The end portions of the two side branches 402 respectively extend to the corresponding side walls 201d. Snap protrusions 201d1 are provided on both side walls 201d, and bayonet openings 4021 are provided on the end portions of the two side branches 402. The end portions of the two side branches 402 respectively form a snap connection with the two snap protrusions 201d1.
[0059] In this way, in order to further improve the fastening effect, a limiting member 500 is further provided on the side wall 201d. A screw hole is provided on the snap protrusion 201d1, and the limiting member 500 is fastened to the snap protrusion 201d1 by a screw BT1. The limiting member 500 is exactly located at the snap connection position, and the limiting member 500 at least blocks a part of the end portion of the side branch 402, so as to limit the side branch 402 from disengaging from the snap protrusion 201d1.
[0060] Here, the limiting member 500 can be a component that only has a limiting function, such as Figure 11 shown, or other components on the disconnect switch, such asFigure 12 As shown in Figure 12 As shown in Figure 12 , the limiting member 500 is one end of the rigid bracket 500', and the other end of the rigid bracket 500' is fastened to the housing of the operation unit layer 100 by a second fastener 501, and the second fastener 501 here is a screw. After the rigid bracket 500' completes the fastening function, it can also play a limiting effect.
[0061] As Figure 13 shown in Figure 13 , for the groove 201a and the transparent shielding member 400, it is not limited to the above-mentioned situation where there must be an indication coverage area 201a1, a communication area 201a2, an indication shielding portion 401, and a side branch portion 402. It is also possible to have no communication area 201a2 and side branch portion 402. In this way, the transparent shielding member 400 can also be fixed by the above-mentioned methods such as screw fastening, adhesive fastening, welding fixation, and snap fixation.
