Abstract

The utility model relates to an automatic resetting bundling reed type plum blossom contact, which comprises a connecting rod whose moving contact conducts electricity, a touch sheet which is matched with the connecting rod of the conducting wire and is arranged in the annular groove of the connecting rod of the conducting wire, an annular supporting frame which is arranged in the inner side of the tough sheet of the moving contact, a tension spring which is bundles on the outer side of the tough sheet of the moving contact, and a static contact which is matched with the moving contact and is arranged on the end of the tough sheet of the moving contact. The contact point of the tough sheet of the moving contact and the annular groove of the electric conduction connecting rod of the moving contact is double circular arc-shaped. The outer part of the contact point is high and the inner part of the contact point is low. The utility model has the advantages that after the static contact is drawn out, the double circuit arcs with a high inner part and a low outer part of the touch sheet of the moving contact are simultaneously appressed in the annular groove of the electric conduction connecting rod of the moving contact, realizes automatic reset, and ensures the safe operation of a handcart type high voltage switch cabinet.

Description

The bundling reed type Mume flower contact automatically resets

The utility model belongs to the high-voltage electrical equipment field, is related to the particularly supporting bundling reed type Mume flower contact that automatically resets of middle high-tension switch cabinet of handcart type high-voltage switch cabinet.

The bundling reed type Mume flower contact, be by cylindrical fixed contact (1), ringwise the assembling moving contact contact (2), the conductive attachment bar (4) of moving contact contact annular brace support (3), moving contact band cannelure, the bundle spring (5) form.Wherein, the way of contact of the cannelure of moving contact contact (2) and moving contact conductive attachment bar (4) is contour Gothic contact, shown in figure seven.This way of contact, after fixed contact (1) is extracted, contact on the moving contact contact (2) can not contact fully with the cannelure of moving contact conductive attachment bar (4) and produce the gap, moving contact contact (2), the moving contact head that moving contact contact annular brace support (3), bundle spring (5) are formed is sagging because of deadweight produces, and can not reset.Because the handcart type high-voltage switch cabinet error can occur in manufacturing and assembling process, moving contact conductive attachment bar (4) and fixed contact (1) be not often on same axis, when error was excessive, moving contact head sagging crossed conference and causes and close car and misplug fault, is an impediment to the safe operation of high-tension switch cabinet.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and existing bundling reed type Mume flower contact is improved, and solves irreducible problem, and a kind of bundling reed type Mume flower contact that automatically resets is provided.

The utility model is achieved in that

It has the moving contact conductive attachment bar of a band cannelure, in the cannelure of this conductive attachment bar, contacted with it moving contact contact is arranged, in moving contact contact inboard one annular brace support is arranged, bundle has tension spring (bundle spring) in the moving contact contact outside, and a fixed contact with matching is arranged in the end of moving contact.The contact position of the cannelure of described moving contact contact and moving contact conductive attachment bar is outer high, interior low not contour Gothic.

The utility model has following advantage compared with the prior art:

1, outer high, interior low not contour Gothic is adopted in the cannelure contact position of moving contact contact and moving contact conductive attachment bar.After fixed contact is extracted, the outer height of moving contact contact, interior low not contour pair circular arc are under the effect of bundle spring, can be close in the cannelure of conductive attachment bar simultaneously, moving contact contact, moving contact contact annular brace support, the moving contact head of bundle spring composition and the axiality of moving contact conductive attachment bar have been guaranteed, overcome the moving contact nose drop, thereby realized automatically reseting.When the journal offset of moving contact conductive attachment bar and fixed contact≤4mm, can guarantee that still plug is reliable, avoid mispluging fault.

2, rational in infrastructure, manufacture craft is simple, is convenient to implement, and only needs to change the shape of moving contact contact and moving contact conductive attachment bar cannelure contact position, can reach automatically reset purpose, guarantees the security of operation of handcart type high-voltage switch cabinet.

Description of drawings:

Figure one is a structural representation of the present utility model;

Figure two is figure one view after fixed contact is extracted;

Figure three is that the utility model inserts view when being offset on fixed contact;

Figure four is the utility model view after skew on the fixed contact is extracted;

Figure five is that the utility model inserts view when being offset under fixed contact;

Figure six is that the utility model is offset the view after extracting under fixed contact;

Figure seven is structural representations of contour pair of circular arc in the prior art.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Shown in figure one, the utility model has a moving contact conductive attachment bar (4), contacted with it moving contact contact (2) is arranged in the cannelure of this conductive attachment bar, in moving contact contact (2) inboard one annular brace support (3) is arranged, bundle has tension spring (bundle spring) (2) in moving contact contact (2) outside, in the end of moving contact contact (2) fixed contact with matching (1) is arranged.The contact of described moving contact (2) is outer high, interior low not contour Gothic with the contact position of the cannelure of moving contact conductive attachment bar, be that outer arc shape contact point is higher than inner arc shape contact point, the center line of two circular arc summit lines and moving contact conductive attachment bar has an angle X.Like this, after just can extracting in fixed contact (1), guarantee moving contact contact (2) under the effect of bundle spring (5), outer height, interior low not contour pair circular arc are close in the cannelure of conductive attachment bar simultaneously, realize automatically reseting, shown in figure two.

When skew in fixed contact (1) appearance or down during skew, still can keep good the contact between the cannelure of moving contact contact of the present utility model (2) and moving contact conductive attachment bar (4) and the fixed contact (1), shown in figure three, five; After fixed contact (1) was extracted, moving contact contact (2) can automatically reset under the effect of bundle spring (5), shown in figure four, six.

Claims
