Description

Technical Field

Background

The switch in the low-voltage electric field is used for controlling the opening and closing of a circuit, and the switch is rapidly opened and closed so as to minimize the influence of an electric arc. At present, the switch operating mechanism is driven by external force applied by a handle and the like, so that the switch moving contact is driven to act, and the switching of the switch state is realized. Due to limitations of the cabinet or mounting location, users sometimes need to operate the switch from different directions, such as front or side. When the side operation is performed, in order to realize the quick switching of the switch, an idle stroke is generally designed in a transmission stroke between the side operation device and the switch operation mechanism, so that a main spring in the operation mechanism can drive a moving contact to quickly act without being interfered by the side operation device after passing through a dead point. However, due to the idle stroke, the lateral operation device cannot be stabilized at two positions corresponding to the switch-on position and the switch-off position, and the lateral operation device may deviate from the two positions during the switch operation, so that indication is ambiguous and safety of the switch operation is seriously affected. In addition, the lateral operation device and the operation mechanism in the current market are in linkage fit by adopting two groups of bevel gears, so that the transmission efficiency is low, and the installation and transmission space required by bevel gear transmission is large, so that the external dimension of the corresponding switch is large, and the processing cost and the manufacturing difficulty of the switch are also increased.

The operation principle of the switch will be described below:

when the initial position of the switch is at the opening position, the first gear plate limiting surface 11212 abuts against the left side surface of the third limiting boss 1010 of the operating mechanism base 100 under the action of the spring force of the spring mechanisms 113 at both sides of the driving plate 112, as shown in fig. 35a. The tooth slot slide plate 15 and the driving slide plate 14 are positioned at the leftmost side of the slide plate slide groove 1002, and the signal switch is in a trigger state at the moment and outputs a brake separating signal to the outside. The right end of the elongated limit groove 152 of the tooth slot slide plate 15 abuts against the limit section 133 of the forward operating shaft 13, as shown in fig. 37. The first driving surface 143 on the driving slide plate 14 abuts against the transmission boss 1321 on the transmission disc 132 of the forward operating shaft 13, so as to limit the forward operating shaft 13 to rotate clockwise, and the transmission disc limiting boss 1322 on the transmission disc 132 abuts against one pair of the fourth limiting bosses 1006 on the operating mechanism base 100, as shown in fig. 35b, so as to limit the forward operating shaft 13 to rotate anticlockwise, so that the forward operating shaft 13 is limited to the opening position. The lateral operation shaft 31 in the lateral operation device 3 is located at a second position corresponding to the switch-off position under the clamping action of the elastic member 32, as shown in fig. 3, the linkage end limiting boss 3132 on the linkage end 313 of the lateral operation shaft 31 abuts against the second limiting surface group 333 on the side cover 33, so as to limit the lateral operation shaft 31 from rotating counterclockwise.

When the switch is switched on from the top of the switch, that is, when the switch is switched on in a forward operation mode, the operating handle 6 is inserted into the handle operating hole 1311 of the forward operating shaft 13, and in combination with the switch position shown in fig. 33, the operating handle 6 is rotated clockwise, the driving boss 1321 on the driving disc 132 of the forward operating shaft 13 is contacted with the first driving surface 143 on the driving slide plate 14, and drives the tooth slot slide plate 15 to slide rightwards together, so that the driving disc 112 is rotated clockwise through the cooperation of the tooth slot gears, and the main springs 1131 on two sides of the driving disc 112 are driven to switch on and store energy, and when the main springs 1131 pass over dead points, the driving disc 112 is rapidly rotated clockwise under the action of the release energy of the main springs 1131, and drives the tooth slot slide plate 15 to slide rightwards rapidly until the left end face of the long-shaped limiting groove 152 on the tooth slot slide plate 15 abuts against the limiting section 133, so that the first limiting is realized; the rightmost end of the tooth slot sliding plate 15 is abutted against the rightmost limiting surface of the sliding plate sliding groove 1002, so that the second limit is realized; the second gear plate limiting surface 11212' of the driving plate 112 abuts against the right side surface of the third limiting boss 1010 of the operating mechanism base 100, so as to realize third limiting, as shown in fig. 36a. In this process, after the main spring 1131 passes the dead point, the first driving surface 143 on the driving slide 14 is separated from the transmission boss 1321, and after the driving slide 14 reaches the rightmost position of the slide chute 1002, the second driving surface 142 thereon abuts against the transmission boss 1321, so that the transmission plate limiting boss 1322 on the transmission plate 132 abuts against another pair of the fourth limiting bosses 1006 on the operating mechanism base 100, as shown in fig. 36b, so as to limit the forward operating shaft 13 to a closing corresponding position (the position differs from the position where the forward operating shaft 13 is located in the opening position by 90 °) to realize irrelevant manual operation. When the drive slide 14 reaches the rightmost position of the slide chute 1002, the pushing of the signal switch 12 is released, and the signal switch 12 switches to output the closing signal. During the closing operation of the forward operation shaft 13, when the slot slide 15 drives the driving disk 112 to move clockwise (refer to the orientation of the driving disk 112 in fig. 10), the output shaft 111 also follows to rotate clockwise. Due to the existence of the idle stroke between the driving groove 3131 on the lateral operation shaft 31 and the driving boss 1114 of the output shaft 111, the lateral operation shaft 31 is kept still, after the idle stroke of about 30 degrees is rotated, the lateral operation shaft 31 is driven to rotate clockwise, in the process, the cam section 312 on the lateral operation shaft 31 pushes the two side elastic pieces 32 to store energy, when the driving boss 1114 drives the lateral operation shaft 31 to rotate 45 degrees, the lateral operation shaft 31 rotates clockwise rapidly under the action of the elastic pieces 32, so that the linkage end limiting boss 3132 on the lateral operation shaft 31 abuts against the first limiting surface group 332 on the side cover 33, the lateral operation shaft 31 is limited to rotate clockwise continuously, and is limited to be at the first position corresponding to the switch-on position through the two side elastic pieces 32. When the switch needs to be operated in the forward direction for opening the switch, the action process is similar to that described above, and will not be repeated.

When the switch is at the opening position and the lateral operation is needed to be closed, the operating handle 6 is inserted into the lateral operation hole 314 of the lateral operation shaft 31, the operating handle 6 is rotated clockwise in the position shown in fig. 3, after the lateral operation shaft 31 rotates by 20 ° idle stroke angle, the groove wall of the driving groove 3131 of the lateral operation shaft 31 in the rotation direction contacts with the driving boss 1114 and starts to drive the output shaft 111 and the driving disc 112 to rotate clockwise (at this time, 50 ° idle stroke exists between the groove wall of the other side of the driving groove 3131 of the lateral operation shaft 31 in the rotation direction and the driving boss 1114 of the output shaft 111), thereby driving the main springs 1131 at both sides of the driving disc 112 to perform closing energy storage, and simultaneously driving the elastic members 32 at both sides of the cam section 312 of the lateral operation shaft 31 to perform energy storage, when the lateral operation shaft 31 drives the output shaft 111 to rotate by 50 °, the main spring 1131 passes over the dead point, due to the idle stroke between the lateral operation shaft 31 and the driving boss 1114, the driving plate 112 rotates clockwise rapidly under the action of the energy released by the main spring 1131, the driving boss 1114 is separated from two side walls of the driving groove 3131 in the rotating direction, the driving plate 112 rotates clockwise and reaches the closing position rapidly, irrelevant manual operation is realized, in the process, the lateral operation shaft 31 rotates by 70 degrees, passes over the dead point position of the elastic piece 32, the lateral operation shaft 31 is in the first position of the elastic piece 32, which corresponds to the closing position of the switch, and is limited at the first position under the action of the elastic piece 32, so that the limiting boss 3132 of the linkage end on the lateral operation shaft 31 abuts against the first limiting surface group 332 on the side cover 33, and the lateral operation shaft 31 is limited to rotate clockwise continuously. In the closing process of the driving disc 112, the driving slide plate 14 and the tooth slot slide plate 15 are driven to slide rightwards together through the cooperation of the tooth slots, after the idle stroke between the second driving surface 142 of the driving slide plate 14 and the transmission boss 1321 is slid, the driving slide plate 14 starts to drive the forward operating shaft 13 to rotate clockwise, and when the driving slide plate 14 reaches the rightmost position of the slide plate slide groove 1002, the second driving surface 142 drives the transmission disc limiting boss 1322 on the forward operating shaft 13 to abut against the limiting surface on the operating mechanism base 100, so that the forward operating shaft 13 is limited on the closing position. Also, when the drive slide plate 14 slides from the left position to the right position, the signal switch is released, so that the signal switch 12 is switched, and a closing signal is output. When the switch needs to be laterally operated to open, the action process is similar to the above, and will not be repeated.
