Description
Technical field
The present invention relates to a kind of connecting component of electrical equipment, especially a kind of connecting terminal block.
Background technique
Widespread need is using bridging or bridge-set in electrical equipment, or needs electric lead carrying out contact connection.One
It is screw terminal that kind, which is typically used for the connecting terminal that electric lead contact flexible is connected,.Traditional screw terminal attached bag
One is included for clamping the screw of electric lead flexible, the screw is rotatable to be connected in corresponding screw hole, will need to connect
The electric lead flexible connect is clamped between the head of screw and connecting component, so that electric lead flexible and contact site are pressed from both sides
Tightly carry out contact connection.To avoid the Flare of electric lead rope-lay strand (being often used thin copper wire) flexible from opening, and in order to
Ensure well contacting between conducting wire and target contact site, end is generally terminated using metallic conduction attachment.Traditional screw
Screw must be fixed on to clamp electric lead flexible in threaded hole by connecting terminal, once and screw loosen, electric lead is just
It is easy to loosen, and it is cumbersome that it, which is clampingly operated,.
Connecting terminal known to another kind is clamped with elastic force.As Chinese invention patent CN102842785A is disclosed
A kind of connecting terminal structure-improved a, comprising: box body, be integrally formed part and including a upper wall, two side walls, a lower wall, a hole
Hole and an elastic slice, the upper wall, two side walls and lower wall are opened in the upper wall and are connected to the space and are somebody's turn to do around a space, the hole is gone out
Box portion outside, the elastic slice are upwardly extended in the space by the lower wall and are extended with an end, which convexedly stretches in the hole；And
One plug connector, including a plug division and a clamping part, the clamping part include holding shrapnel and once holding shrapnel on corresponding one；
The plug division penetrates the space and is plugged in the box body, and the end contact of the elastic slice is in the plug division, and the plug division pushes
In end to the space of the elastic slice.It is designed with this, there is the present invention and increase overall structural strength and improve elastic slice clamping
The effect of power can be such that transmission line is more firmly clamped by elastic slice when elastic slice is when clamping transmission line.But the middle connecting terminal is still
It is so combined using various parts, still inevitably occurs generating showing for insufficient clamping force since part cooperates in use process
As.
In addition, in connecting terminal block, in order to which the connecting terminal block of different units to be shorted, shorting pin is commonly used to will not
Connecting terminal block with unit is shorted.And elastic slice is easy to fall off damage during grafting repeatedly, so that wiring
Terminal block loses connection function.
Summary of the invention
Based on this, a technical problems to be solved of the invention are the elastic slice and metal plate for improving connecting terminal block
The Joint Properties of ontology, to extend the service life of connecting terminal block.
Another technical problems to be solved of the invention are that be further reduced structure of the elastic slice on clamping direction wide
Degree, to further reduce the overall dimensions of connecting terminal block.
The present invention provides a kind of connecting terminal block,
The present invention provides a kind of connecting terminal block, has metal plate main structure (10) and elastic slice (40), the metal plate
Main structure (10) be rectangular hexahedron, be provided at least one concave part (30), in order to the elastic slice (40) elasticity
Engagement has the elasticity being at least located remotely from each other between the first arm (12) and the second arm (14) of the elastic slice (40)；, special
Sign is: the side wall (20) inconsistent with the first arm (12) of the elastic slice and the second arm (14) in the concave part (30)
Corner be formed as it is symmetrical repeatedly into stairstepping.
Preferably, it is described it is symmetrical repeatedly into stairstepping corner between form tool there are three different sizes
The clearance space of L1, L2 and L3, wherein L1 < L2 < L3 < metal plate main structure (10) lateral dimension.
