Embodiment
In order to make object of the present invention, technical scheme and Advantageous Effects thereof more clear, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.Should be understood that, the embodiment described in this specification is only used to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1 to Fig. 4, in drawout cubicle of the present invention, the secondary connected structure of drawer unit comprises fixed contact mounting panel 10, fixed contact body 12, moving contact base 20, moving contact body 22, drawer backboard 30 and guider.Wherein, fixed contact body 12 is by clamping or be spirally connected and be fixed on the fixed contact mounting panel 10 of drawout cubicle, and moving contact body 22 is by clamping or be spirally connected and be fixed on moving contact base 20, and moving contact base 20 floats and is arranged on drawer backboard 30; Guider is arranged between fixed contact mounting panel 10 and moving contact base 20, leads to the grafting of moving contact body 22 and fixed contact body 12.
Guider comprises the guide finger 40 and lead 42 that are in alignment with each other.Guide finger 40 adopts high strength steel material to make, and its surface is through wear-resisting, corrosion treatment; The diameter of guide finger 40 is greater than 5mm, and its stiff end is fixed on fixed contact mounting panel 10, and inserted terminal 400 is processed into taper shape.Lead 42, for being arranged on the projection on moving contact base 20, offers the jack 420 suitable with guide finger 40 in it, the inserted terminal of jack 420 is tubaeform; Lead 42 is one-body molded with moving contact base 20, and its material is PC+ glass, and the pure PC of strength ratio is better, is therefore more conducive to avoiding wounding.
The centre of moving contact base 20 offers two large square holes of modularization, and it can clamping moving contact body 22, also can clamping two moving contact bodies 22.
The mounting means of moving contact base 20 on drawer backboard 30 is as follows: on moving contact base 20 and drawer backboard 30, correspondence offers multiple circular hole respectively, and circular hole on moving contact base 20 is more bigger than the circular hole on drawer backboard 30; By bolt 50 successively through moving contact base 20, ripple pad 52 and drawer backboard 30, then use nut check, can by moving contact base 20 floating connection on drawer backboard 30,52, ripple pad is between moving contact base 20 and drawer backboard 30.Ripple pad 52 can make moving contact base 20 have certain flying ability when being subject to External Force Acting, without during External Force Acting keep inactive state, therefore, in drawer backboard 30 swapping process, if there is error in the docking of guide finger 40 and lead 42, moving contact base 20 can do appropriate displacement under the drive of lead 42, thus when not damaging any element, makes moving contact body 22 and fixed contact body 12 aim at grafting.
It should be noted that, although in the shown embodiment, guide finger 40 is fixed on fixed contact mounting panel 10, lead 42 is arranged on moving contact base 20, but in other interchangeable execution modes, installation/the shaping position of guide finger 40 and lead 42 also can exchange, and this does not affect the guide effect of guider.
Known by describing above, in drawout cubicle of the present invention, the secondary connected structure of drawer unit at least has following beneficial effect:
1) inserted terminal of guide finger 40 is conical, and the inserted terminal of lead 42 is tubaeform, the error within the 2mm existed in either direction when the two cooperation can eliminate moving contact body 22 and 22 grafting of fixed contact body substantially;
2) guide finger 40 adopts metal material, and lead 42 adopts the engineering plastics of high strength to make, and therefore guider is high-strength structure, not easily breaks and is out of shape;
3) bolt 50 and ripple pad 52 is utilized by moving contact base 20 floating connection on drawer backboard 30, moving contact body 22 is made to have certain activity surplus when being subject to External Force Acting, thus displacement can be carried out, to guarantee that moving contact body 22 and fixed contact body 12 can aim at grafting according to needing of regulating of leading.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the present invention is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the present invention.
