Description
Technical field
The present invention relates to the break group of goat, the break particularly to be swung with die cavity fixed contact piece
Group.
Background technology
The design of existing break group be the punch forming of 0.5-0.6 millimeter sheet coppers is socketed in for left and right static contact fingers it is quiet
On the fixing bolt of contact group, the elasticity and auxiliary reinforcing chip itself bullet of left and right contact strip made of sheet copper punching press itself are utilized
Property complete clamping to movable contact ring, carry out switching on and off for holding circuit, such left and right contact strip is in the more numbers of movable contact ring
After squeezing into extraction, left and right contact strip produces metal fatigue breakage phenomenon and chucking power declines phenomenon, is influenceing goat circuit just
There is flash phenomenon in often conducting, disconnection, control and indication circuit, and Railway Site signal worker will periodically irregular artificial tune
Whole left and right contact strip is to the chucking power of movable contact ring, the time consuming normal operation for taking material and influenceing railway.
The content of the invention
It is an object of the invention to provide a kind of break group to be swung with die cavity fixed contact piece.
The present invention technical solution be：A kind of break group to be swung with die cavity fixed contact piece, including bottom
Seat (1), upper cover plate (2), left and right static contact fingers (3), base (1) middle part are provided with R types cavity (4), and R types cavity (4) section is top
Portion's fulcrum block (4-1) and bottom sector or triangular cavity (4-2) form, and are provided with R types cavity (4) and R types cavity (4) coordinates
Corresponding left and right static contact fingers (3), left and right static contact fingers (3) top fulcrum section coordinate with R type cavity tops fulcrum block, left and right
Static contact fingers (3) bottom section is rectangle, and R types cavity (4) top fulcrum block is matched somebody with somebody with left and right static contact fingers (3) top branch crawl
Close, R types cavity (4) bottom is more than the bottom of left and right static contact fingers (3), and left and right static contact fingers (3) can be medium and small in R types cavity (4)
Distance swings, and left and right static contact fingers (3) both sides are provided with spring (5), and base (1) top bolt is provided with binding post (6), connect
Line terminals (6) are connected with left and right static contact fingers (3) by wire (7), and base (1) is provided with upper cover plate (2).
The cross sectional shape of R types cavity (4) is the intersecting garden die cavity (4- that top circular intersects with bottom sector or triangle
4), the top circular and tangent tangent circle die cavity (4-5) of bottom sector or triangle, linear top shape and bottom sector or triangle
Die cavity (4-7), the top cross that the L-type die cavity (4-6) of shape connection, linear top shape are connected with bottom sector or triangle
Cross die cavity (4-8), the top M shape that shape is connected with bottom sector or triangle are connected with bottom sector or triangle
Rice font die cavity, left and right static contact fingers (3) top shape are corresponding with the cooperation of R types cavity (4) top shape.
The present invention abandons the mode that old type tube break group fixes left and right contact strip with binding post bolt, using upper cover plate
Left and right contact strip is fixed with die cavity, the segmentation of fixing bolt link terminal is fixed, and then reconnects the mode being integrated.This
Sample or so contact strip can design to be widened to both sides displacement, and the distance between left and right contact strip is not limited by fixing bolt position,
Thus greatly improve the insulating properties between the contact strip of left and right and reduce creepage phenomenon.The fixation of the present invention
Bolt binding post need not fix left and right contact strip, not limited by left and right contact strip, can be by fixing bolt binding post bottom
Design shifts up 5-7 millimeters, uses present 5x30 millimeter brass bolts instead 5x25 millimeter brass bolts, that is, saves material and increase again
The ground clearance 5-7 millimeters of stud base reach 11-12 millimeters, and (the fixing bolt bottom of existing break seat is because being designed
Ground clearance highest is limited also with regard to 5 millimeters) while also increase insulating properties.Break group of the present invention saves copper material consumption
50%, save phenolic glass fiber 10-15%.It is equal to movable contact ring that left and right contact strip can be achieved using the break group of the present invention
Permanent contact, left and right contact strip can be achieved to the linear contact lay of movable contact ring, make break group it is non-maintaining during service life,
Without periodically irregular adjustment left and right contact strip to the pressure of movable contact ring.Artificial, Master Cost has been saved, has improved society's effect
Benefit and production efficiency.
