Background technology
The patent No. is that the Chinese utility model patent of ZL00243308.7 discloses the break assembly in a kind of goat, comprise contact strip, reinforcing chip, break piece and connecting element, wherein, six contact strips and corresponding reinforcing chip are fastened in the mounting groove of non-conductive break piece by connecting element, in the middle of two mounting grooves is the long isolating bar of a projection, this long isolating bar is provided with an inside recess at the end away from contact strip and reinforcing chip fixed part, the opposite side of corresponding mounting groove is provided with a protuberance, reinforcing chip is fitted on the contact strip, the turn of bilge of the corresponding contact strip of its arc flex point, reinforcing chip be shorter in length than contact strip, be provided with the short isolating bar of projection between the described connecting element.
But the problem that this break assembly exists is that reinforcing chip is shorter than contact strip, insert in the break component process at the contact heel ring, the contact heel ring is when contacting with contact strip termination bending arc and rolling slips into downwards, friction force between itself and the contact strip is increasing, cause the wearing and tearing of break assembly to increase like this, reduce service life.And be one of important indicator of break assembly service life.
Therefore, the life-span of how to improve the break assembly just becomes the technical barrier that this technical field faces.Its another one shortcoming is that mounting groove may descend ponding at weather such as rain, snow, mists, causes between sheet (referring between two break sheets or two reinforcing chips) short circuit.Therefore solve that short circuit also is a technical matters that faces between sheet.
Summary of the invention
The purpose of this utility model is to provide a kind of by reducing between contact heel ring and the contact strip frictional loss and then improving the break assembly in service life.
For achieving the above object, the utility model is taked following technical scheme:
Break assembly in a kind of goat of high life, comprise contact strip, reinforcing chip, break piece and connecting element, wherein, contact strip and corresponding reinforcing chip are fastened in the mounting groove of non-conductive break piece by connecting element, described contact strip is positioned at the inboard, described reinforcing chip is positioned at the outside, in the middle of two mounting grooves is the long isolating bar of a projection, this long isolating bar is provided with an inside recess at the end away from contact strip and reinforcing chip fixed part, the opposite side of the corresponding mounting groove of described break piece is provided with a protuberance, reinforcing chip is fitted on the contact strip, being provided with the short isolating bar of projection between the described connecting element, it is characterized in that: fits in the bottom of the bending arc on described reinforcing chip and described contact strip top.
A kind of optimal technical scheme is characterized in that: the termination of described reinforcing chip and the termination of described contact strip are flush.
A kind of optimal technical scheme is characterized in that: described bending arc is made up of the geometric configuration that inside and outside tangent circular arc line combines with straight line.
A kind of optimal technical scheme is characterized in that: be provided with flame diversion trough in the described mounting groove.
Beneficial effect:
The utility model has the advantages that:
Switching machine of the present utility model is under the energising running condition, when the contact heel ring insertion break assembly of contact heel group surpasses the specialized range of 4mm, have only the bottom of the bending arc on described reinforcing chip and described contact strip top to fit, just can reach needed pressure between contact strip and the contact heel ring, and reduce the frictional loss between contact heel ring and the contact strip, the service life of having improved the break assembly.Flame diversion trough can be avoided short circuited generation between sheet.
Below in conjunction with the drawings and specific embodiments the utility model is further specified, but and do not mean that restriction the utility model protection domain.
Description of drawings
Fig. 1 is the structural representation of break assembly in the goat of the present utility model;
Fig. 2 is the cutaway view of break assembly in the goat of the present utility model.
The specific embodiment
Embodiment 1
As shown in Figure 1, 2, be the cutaway view of break assembly in the structural representation of break assembly in the goat of the present utility model and the goat of the present utility model respectively.The break assembly comprises contact strip 1 in the goat of the present utility model, reinforcing chip 2, break piece 3 reaches by nut, spring chair, the connecting element that bolt is formed, wherein, contact strip 1 and corresponding reinforcing chip 2 are fastened in the mounting groove 4 of non-conductive break piece 3 by connecting element, in the middle of mounting groove 4 is the long isolating bar 5 of a projection, this long isolating bar 5 in the end away from contact strip 1 and reinforcing chip 2 fixed parts is provided with to a recess 6, relative, the other end of mounting groove 4 is provided with a protuberance 7, reinforcing chip 2 is fitted on the contact strip 1, fit in the bottom of the bending arc on the bending arc on reinforcing chip 2 tops and contact strip 1 top, be provided with the short isolating bar (not shown) of projection between the described connecting element, described long isolating bar 5 both sides are provided with flame diversion trough 8.
The termination of the termination of described reinforcing chip 2 and described contact strip 1 is flush.The bending arc of described contact strip 1 and contact heel loop contacts is made up of the geometric configuration that inside and outside tangent slick and sly camber line combines with straight line.
During installation, contact strip 1 and reinforcing chip 2 are fit together, after inserting mounting groove 4, use nut, spring chair, bolted are on basal plane, and the arc column face of the protuberance 7 of vertical its baseplane contacts on the cambered surface of reinforcing chip 2 and the break piece 3, and a circular arc cylinder and a Plane intersects with the corresponding recess 6 of circular arc cylinder of protuberance is arranged on the plane of break piece 3, form two and contact perpendicular to the supporting-line on the long isolating bar 5 of baseplane and the face of contact strip.The circular arc cylinder of described recess 6 also can be other concave panels.Stable and the vertical bottom face because of the supporting-line on the long isolating bar 5, and make contact strip 1 operation pressure stable, improved this reliability of products.Be the circular arc cylinder of recess 6 because of the circular arc cylinder of protuberance 7 is corresponding again,, this product life be further improved so when contact strip 1 is in running order, can improve the strained condition at the supporting-line place of contact strip 1 on long isolating bar 5.In addition, the major axis of contact strip 1 and corresponding reinforcing chip 2 and its attachment face have an angle, guaranteeing that break component feature space position dimension is constant like this, promptly have under the condition of interchangeability, make that to carry the attachment face of spot film 1 on break piece 3 parallel with its baseplane, to increase the distance of baseplane and fastener and bottom surface, promptly increase leakage length, bolt, spring chair, nut are fixed on the break piece made from insulating material 3, external wire can be connected on the bolt with nut, by the prolate stepped hole on the break piece 3, can be fixed on the break assembly on the support.
