Detailed Description

For further illustration of the various embodiments, the utility model is provided with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present utility model. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

The utility model will now be further described with reference to the drawings and detailed description.

Referring to fig. 1 to 4, the present embodiment provides a side-operated disconnecting switch, which includes a housing 10, an operating mechanism 20 disposed in the housing 10, and a contact system, wherein the contact system includes a sliding beam 31 with a moving contact group and contact blades 32 symmetrically distributed on both sides of the sliding beam 31, and the operating mechanism 20 is in driving connection with the sliding beam 31; specifically, the structure, connection and switching-on/off transmission modes of the operating mechanism 20 and the contact system all adopt the prior art, for example, the operating mechanism 20 is an energy storage operating mechanism with a driving shaft 21 in the prior art, and the like. The specific structure and the opening and closing transmission action are not described in detail. More specifically, the housing 10 includes an upper shell 11 and a lower shell 12, the upper shell 11 and the lower shell 12 are covered to form an inner cavity, and the operating mechanism 20 and the contact system are disposed in the inner cavity.

The same side end (such as the front side end) of the shell 10 is provided with a handle 40 and an auxiliary switch 60, and the handle 40 is in transmission connection with the operating mechanism 20; the triggering end 61 of the auxiliary switch 60 extends into the housing 10, the housing 10 is further provided with a push plate 71 and an elastic member 72, the elastic member 72 and the triggering end 71 of the auxiliary switch 60 are located on the same side of the push plate 71 and simultaneously abut against the push plate 71, one side of the push plate 71, which is away from the elastic member 72 and the triggering end 61 of the auxiliary switch 60, is provided with an extension part 711 corresponding to the sliding beam 31, the extension part 711 is located between a first position of the push plate 71 abutting against the elastic member 72 and a second position abutting against the triggering end 61 of the auxiliary switch 60, i.e. a position of the push plate 71 for abutting against the elastic member 72 is defined as a first position, a position for abutting against the triggering end 61 of the auxiliary switch 60 is defined as a second position, and the extension part 711 is located between the first position and the second position.

When the opening and closing operation is carried out, the handle 40 is rotated, the handle 40 rotates to drive the operating mechanism 20 to act, and then the sliding beam 31 is driven to slide to realize the opening and closing of the isolating switch, so that the lateral operation of the handle 40 is realized; meanwhile, when the sliding beam 31 slides to close the switch near the front side end, the sliding beam 31 will abut against the extension part 711 of the push plate 71 and push the push plate 71 to move forward together, and in the process of moving the push plate 71 forward, the elastic piece 72 and the elastic piece of the triggering end 61 of the auxiliary switch 60 will be pushed at the same time, the push plate 71 is buffered and stably translated, and finally the auxiliary switch 60 is triggered; meanwhile, if the stroke of pushing the push plate 71 by the sliding beam 31 is too large (i.e. the push plate 71 has a forward moving stroke after completing the triggering of the auxiliary switch 60), the push plate 71 can continuously compress the elastic member 72, so that the elastic member 72 absorbs the excessive displacement, thereby protecting the auxiliary switch 60 and ensuring the stable triggering of the auxiliary switch 60. When the slide beam 31 slides backward, the push plate 71 loses the acting force exerted by the slide beam 31 and resets under the action of the elastic member 72 and the elastic piece of the triggering end 61 of the auxiliary switch 60, and the auxiliary switch 60 is released from triggering and waits for the next closing trigger. The triggering structure of the auxiliary switch is simple and ingenious in design. The lateral arrangement of the handle 40 allows for the provision of upper and lower surface positions for the stacking of a plurality of switches.

Further, in this embodiment, a limiting groove 101 is further formed in the housing 10, the limiting groove 101 is provided with a yielding gap 102, the push plate 71 is disposed in the limiting groove 101, and the extension portion 711 extends out of the limiting groove 101 through the yielding gap 102 to correspond to the sliding beam 31. By the arrangement, the push plate 71 can be well limited, the push plate 71 is prevented from shifting, and stable triggering of the auxiliary switch 60 is better ensured.

Specifically, the elastic member 72 is a spring, a blind hole is formed in the inner wall of the housing 10, one end of the spring is assembled in the blind hole, and the other end of the spring abuts against the push plate 71. The stable assembly of the spring is realized. Of course, in other embodiments, the elastic member 72 may be replaced by elastic members such as elastic sheets.

Specifically, the auxiliary switch 60 is embedded in the side wall of the housing 10 and is flush with the outer surface of the side wall, so that the rotary operation of the handle 40 is not affected by the auxiliary switch 60, and the appearance is more concise and attractive.

The handle 40 is in driving connection with the drive shaft 21 of the operating mechanism 20 via a gear assembly 50. Specifically, the gear transmission assembly 50 includes a connecting shaft 51, a first bevel gear 52 and a second bevel gear 53, the connecting shaft 51 is rotatably assembled on a side wall of the housing 10, the handle 40 is assembled at an outer end of the connecting shaft 51, the first bevel gear 52 is sleeved at an inner end of the connecting shaft 51, the second bevel gear 52 is sleeved on the driving rotating shaft 21 and meshed with the first bevel gear 51, and the cooperation of the first bevel gear 51 and the second bevel gear 52 realizes reversing transmission. When the handle 40 is rotated, the connecting shaft 51 and the first bevel gear 52 rotate together, so that the second bevel gear 53 drives the driving rotating shaft 21 of the operating mechanism 20 to rotate, the operating mechanism 20 is driven to act, the structural design is simple, and the transmission is stable.

Furthermore, the first bevel gear 52 and the second bevel gear 53 are all bevel gears with incomplete teeth, so that the teeth which do not participate in transmission are reduced, the layout space is not excessively occupied, and the isolating switch can be designed to be more compact and smaller in size.

Specifically, in this embodiment, the upper and lower surfaces of the housing 10 are fixed with mounting brackets 80, and the mounting brackets 80 are used for fixedly connecting with an external bracket, so that the upper and lower surfaces of the isolating switch can be mounted and fixed.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
