Below in conjunction with accompanying drawing, the utility model is described in detail.

Construction of switch comprises shell, handle, cover plate, insulator foot, the bottom of shell is flexibly connected insulator foot, and cover plate is arranged on the both sides of shell, and handle is arranged on shell, prevent the unexpected landing of handle, the concrete structure of each parts in description the utility model of lower mask body.

In figure, handle 14, in block structure, handle has an open-work, connection several contact knife sheet (not shown) at the interval, bottom of handle;

The structure of described shell cross section substantially in arc-shaped, stretching out of two free end levels of circular arc, wherein each symmetry in the both sides of outer casing top surface be provided with several groove, groove interval is arranged, contact knife sheet is arranged in groove, handle strip movable touch knife sheet is movable in groove, wherein the both sides of cover top portion symmetry are also provided with a plug containing hole 12 simultaneously, plug containing hole 12 is a blind hole, plug is placed in plug containing hole 12, plug containing hole 12 is positioned at the not-go-end of handle scope of activities, when handle strip movable touch knife sheet stops at the not-go-end of handle scope of activities, the top of plug is plugged in open-work, prevent handle movable, preferred shell is split-type structural, the structure of each parts of description of lower mask body and connecting relation thereof.

In figure, shell is split-type structural, comprise left shell 1, right shell 2, and left shell, right shell are symmetrical structure, the structure of a cross section substantially in arc-shaped that what left shell, right shell were relative be joined together to form, makes the curved or ramp structure of the end face of housing, such structure is adopted to be comply with track when handle spins upside down, in the utility model, preferred shell is the structure of arc-shaped, and stretching out of two free end levels of circular arc, describes the structure of housing below for right shell.

Right shell comprises the supporting surface 3 of arc, free end wherein bottom supporting surface extend horizontally away a mounting edge 4 laterally, on the end face of supporting surface top, interval arranges several protrusion 5, simultaneously on supporting surface length direction, interval arranges several groove 6 on the support surface, groove 6 digs, and forms the space of a walking.Groove 6 extends to the position near mounting edge from the end face arranging protrusion, between each groove 6, the back side of supporting surface arranges several parallel dividing plate, dividing plate extends to the position concordant with mounting edge position from the top in curved support face, and the length direction of dividing plate and horizontal plane, Width and plane-parallel, the both sides free end of supporting surface seals and forms baffle plate 8 by the dividing plate on the most both sides of supporting surface length direction.

Mounting edge 4 is arranged the identical or different mounting groove of several shape, remaining parts can be connected by screw in mounting groove, the such as parts such as binding post, contact, the bottom installing insulating base 9 of shell, insulator foot 9 is substantially in a rectangular configuration, and on the end face of insulator foot, interval arranges several socket and installing hole, installs the parts such as binding post or contact in socket, insulator foot 9 is installed the conducting strip tilting to tilt, the degree of depth of socket is dark crosses the conducting strip tilting to tilt simultaneously.

The structure of left shell is described for left shell below again, left shell and right shell structure symmetry, unique difference be left side curved support face end face on there is several protrusion jack (not shown), protrude jack corresponding with salient position, protruding adaptive being inserted in protrudes in jack, uses and protrudes and protrude jack and two symmetrical half shells are joined together to form a complete housing.

In order to insulator foot install more firm, convenient, in the downside of every block baffle plate, mounting blocks 10 is set, the bottom of mounting blocks arranges inserted block 11, the middle part of mounting blocks 10 is provided with accommodation hole simultaneously, the parts that in accommodation hole, reeve coordinates with it, inserted block injects in the jack of the correspondence be mated simultaneously, and screw can not be used so just two parts directly can be coupled together.The insulator foot corresponding with mounting blocks 10 position is provided with contiguous block 19, and the middle part of contiguous block 19 also has accommodation hole, and contiguous block 19 also arranges the jack with inserted block adaptation, the accommodating contiguous block of accommodation hole of mounting blocks 10, inserted block inserts in jack simultaneously simultaneously.

The utility model is applied on switch usually, it is the space of the blade of knife switch activity be connected with handle 14 in groove, because the both sides of shell are arcuate structures in the utility model, and both sides are provided with the space of contact knife sheet activity, therefore handle of the present utility model can be movable back and forth in the both sides of shell, and the bottom of shell is connected with insulator foot 9.Sometimes contact knife sector-meeting is because unexpected landing, in order to avoid this is unexpected, at the middle part of shell, one blind hole is set, the position of blind hole is arranged on position when handle strip movable touch knife sheet and contact making current, lays a plug 13 in blind hole, and the open-work arranged in the middle part of handle 14 is plug through hole 15, the centre of plug through hole 15 has a slot 16, when blade of knife switch to contact with contact etc. be energized time, the upper end of plug is plugged in the slot 16 of handle, and blade of knife switch can be avoided like this to be pushed away by unexpected.

Described plug is substantially in a columned structure, and the top of plug is the ring of one and slot 16 adaptation, and the lower end of plug is placed in blind hole.

For the sake of security, the end face of mounting edge is arranged cover plate 17, prevent from getting an electric shock, entering the accidents such as dust, the bottom of cover plate arranges several inserted sheet 18, and described cover plate is plugged on mounting edge by inserted sheet, cover plate prevents dust etc. from entering in switch, also prevent from getting an electric shock and occur, more firm in order to what install, cover plate side end also arranges several inserted sheet, the inserted sheet grafting of cover plate side like this enters on shell, and the intensity of connection increases.

The bottom of described shell arranges several buckle structure, insulator foot is arranged hole clipping that is several and buckle structure adaptation, buckle is inserted in hole clipping, uses this kind of structure can avoid using the connectors such as screw, and does not need instrument just both can be arranged on one piece.

Because this structure is applied on switch, therefore base also can install the parts such as conducting strip, U-shaped folder, conducting strip one end is connected with U-shaped folder, and U-shaped folder has connecting hole, in connecting hole, locking mechanism is installed, locking mechanism can be metal wire, and metal wire links together through the two ends of connecting hole line again, and metal line materials chooses manganese steel in the switch, locking mechanism plays the effect of locking blade of knife switch, blade contacts better with conducting strip, not easily loosens, and the utility model is newly suitable for three-phase electricity.

All parts in the utility model breaker in middle are same as the prior art, structure and the syntagmatic thereof focusing on each parts of the present utility model.

These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; within all spirit in the utility model embodiment and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection range of the utility model embodiment.
