Example 1
As shown in fig. 1-4B, an embodiment of the present utility model provides an isolating switch, which includes:
the operation unit layer 1 and the switching unit layer 2.
An operating mechanism is provided inside the operating unit layer 1.
The switching element layer 2 includes a case having a substantially rectangular cross-sectional shape, and a central bearing region is formed in a central region of the case, the central bearing region being located substantially at a central portion of the case. On both sides of the central bearing area.
The movable contact disc 3 is rotatably arranged in the central bearing area of the switch unit layer 2, the fixed contacts 4 are respectively arranged on the periphery of the movable contact disc 3, and the on-off of the switch is realized through the connection and the separation of the movable contact disc 3 and the fixed contacts 4.
The movable contact plates 3 in each switch unit layer 2 have the same structure, and two adjacent movable contact plates 3 are in plug-in fit, and the specific structure is as follows:
the movable contact panel 3 comprises a base 31 and a cover 32, wherein the base 31 and the cover 32 are connected by a buckle, and besides, the movable contact panel is usually fixed by ultrasonic welding in the field, so long as the stable fit between the base 31 and the cover 32 can be ensured.
A rib 31a is formed on the upper surface of the cover 32, and a fitting groove 31b having a shape matching that of the rib 31a is formed on the lower surface of the base 31. The two ribs 31a and the two mating grooves 31b are arranged offset from the rotation center O of the movable contact panel 3. In such a design, the convex rib 31a of the movable contact disc 3 is inserted into the matching groove 31b of the other adjacent movable contact disc 3, so that the force arm for transmission is larger when the transmission is realized between the convex rib and the matching groove. Specifically, the ribs 31a are formed such that the ribs 31a protruding from the upper surface of the cover 32 are formed on the base 31, and the corresponding positions of the cover 32 are through holes, so that the ribs 31a penetrate the cover 32 to be formed on the upper surface of the cover 32 after the cover 32 is assembled with the base 31.
After the base 31 and the cover 32 are mated, they together form a mounting space 31c, and the mounting space 31c is used for mounting the conductive component.
The specific conductive component structure is as follows:
the contact piece 33 is substantially elongated, and two limit bosses 33a are formed on the contact piece 33 by processing, for example, one of the two contact pieces 33 is substantially identical. When the two contact pieces 33 are stacked, the two limit bosses 33a abut against each other so that the two contact pieces 33 form an initial gap at the end positions, and the distance of the initial gap is matched with the thickness of the fixed contact 4, so that the fixed contact 4 enters the gap to be matched with the two contact pieces 33. In addition, the integral contact piece 33 may be provided with a stopper boss 33a, the other contact piece 33 may not be provided with the stopper boss 33a, and the stopper boss 33a may abut against the surface of the other contact piece 33 to form an initial gap.
A guiding surface 33b is formed on a side of the contact piece 33 adjacent to the fixed contact 4, and the guiding surface 33b is a chamfer or a guiding surface, so that the fixed contact 4 can enter the initial gap. An arc striking angle 33c is formed on the other side surface of the contact piece 33, and the arc striking angle 33c extends in a direction away from the guide surface 33 b.
The elastic clip 34, which has a substantially C-shaped cross-sectional shape, includes two elastic portions 34a and a connecting portion 34b, and the two elastic portions 34a are connected by the connecting portion 34b, so that the two elastic portions 34a are disposed at intervals.
The two stacked contact pieces 33 are covered by the elastic clip 34 in a semi-surrounding manner, so that the conductive assembly is formed into a whole, specifically, one of the two elastic portions 34a abuts against the upper surface of the upper contact piece 33, the other one abuts against the lower surface of the lower contact piece 33, and the connecting portion 34b is positioned on the left side surface of the two contact pieces 33, so that the two elastic portions 34a are used for resetting the contact pieces 33 (resetting when the fixed contact 4 is separated from the initial gap), and the conductive assembly is formed into a whole.
In order to be beneficial to the overall stability of the conductive component, a first limiting structure can be further added. Specifically, for example, the first boss assemblies 33d (each boss assembly has two bosses) are disposed on the left side surfaces of the two contact pieces 33 at intervals, and the connection portion 34b is located in the first boss assembly 33d (between the two bosses) to perform limiting, so that the two contact pieces 33 can be prevented from being separated from the elastic clip 34 along the length direction X of the elastic clip 34. Besides the first limiting structure, the first groove may be used to replace the first boss component 33d, and the connecting portion 34b is located in the first groove, which may also achieve a similar effect. Besides, the first limiting structure may also be a structure in which a notch is formed in the connecting portion 34b, corresponding protrusions are formed on the two contact pieces 33, and the protrusions are inserted into the notch, so that a similar effect can be achieved. The first limiting structure of the present utility model mainly adopts such a step structure that utilizes the concave-convex fit, so as to prevent the two contact pieces 33 from being separated from the elastic clip 34 along the length direction X of the elastic clip 34.
In order to facilitate the overall stability of the conductive assembly, a second spacing structure may also be added. Specifically, for example, the second boss assemblies 33e (each boss assembly has two bosses) are disposed on the right side surfaces of the two contact pieces 33 at intervals, the bent portions 34a1 are disposed on the right sides of the two elastic portions 34a, and the bent portions 34a1 are located in the second boss assemblies 33e (between the two bosses) to limit positions, so that the two contact pieces 33 can be prevented from being separated from the elastic clip 34 along the length direction X and the width direction Y of the elastic clip 34. Besides the second limiting structure, the second groove can be used to replace the second boss component 33e, and the bending portion 34a1 is located in the second groove, which can also achieve a similar effect. In addition, the second limiting structure may also be a structure in which notches are formed in the two elastic portions 34a, corresponding protrusions are formed on the two contact pieces 33, and the protrusions are inserted into the notches, so that similar effects can be achieved. The second limiting structure of the present utility model mainly adopts such a stepped structure using a concave-convex fit, thereby preventing the two contact pieces 33 from being separated from the elastic clip 34 in the length direction X and the width direction Y of the elastic clip 34.
