Abstract
The utility model discloses a kind of anti-short-circuiting bar, including, the cutting ferrule of two connections arranged side by side and be separately positioned on the screw in described cutting ferrule, each described card puts the card trepanning being provided with a described screw of restriction, one end of each described screw is provided with a plastic cap, the other end is provided with screw thread, the mid portion of described screw is shiny surface, the shiny surface of described screw can be the most movable in card trepanning, and described anti-short-circuiting bar all includes basic unit, copper plate, tin coating except the other parts of plastic cap.The anti-short-circuiting bar of this product has that electric conductivity is strong, the advantage of anti-corrosion.
Description
Technical field
This utility model relates to electrical connections field, is specifically related to a kind of anti-short-circuiting bar.
Background technology
Cutting ferrule and the screw of the anti-short-circuiting bar of prior art are typically separate, carry out group again during installing
Dress, owing to the volume of cutting ferrule and screw is the least, so is easy to fall screw in insertion cutting ferrule during work
Falling to the ground, be so inconvenient to work, also the screw of supporting specific model generally wanted by the cutting ferrule of every kind of model, but each
The production of single screw all can difference, thus there will be screw and the unmatched phenomenon of cutting ferrule；Prior art
Anti-short-circuiting bar usually by corrosion, can reduce serviceability and the service life of anti-short-circuiting bar.
Utility model content
This utility model provides a kind of anti-short-circuiting bar, to solve the problems referred to above.
This utility model embodiment provides a kind of anti-short-circuiting bar, including the cutting ferrule of, two connections arranged side by side and be separately positioned on
Screw in described cutting ferrule, each described card puts the card trepanning being provided with a described screw of restriction, each described screw
One end of nail is provided with a plastic cap, and the other end is provided with screw thread, and the mid portion of described screw is shiny surface, described spiral shell
The shiny surface of silk nail can be the most movable in card trepanning, and described anti-short-circuiting bar all includes basic unit, plating except the other parts of plastic cap
Layers of copper, tin coating.
Preferably, the thickness of described copper plate is 2.5～4.0 μm.
Preferably, the thickness of described tin coating is 3.0～6.0 μm.
Compared with prior art this utility model has the advantage that
1, the card trepanning of the cutting ferrule of anti-short-circuiting bar of the present utility model can control the smooth part of screw in card trepanning
Move freely, thus do not have screw come off difficult target-seeking situation occur；
2, the appearance of the metal part of anti-short-circuiting bar of the present utility model carries out copper facing and tin plating process successively, so plates
Layers of copper, tin coating can increase the electric conductivity of anti-short-circuiting bar, and can prevent anti-short-circuiting bar generation corrosion.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of anti-short-circuiting bar of the present utility model.
Fig. 2 is the structural representation of the cutting ferrule of anti-short-circuiting bar of the present utility model.
Reference:
1, cutting ferrule；
2, screw；
3, plastic cap；
4, card trepanning.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The all other embodiments obtained, broadly fall into the scope of this utility model protection.
Embodiment:
As shown in Figure 1 and Figure 2, this utility model embodiment provides a kind of anti-short-circuiting bar, including, the card of two connections arranged side by side
Overlap 1 and be separately positioned on the screw 2 in described cutting ferrule 1, the upper surface of described cutting ferrule 1 is provided with the card trepanning of a circle
4, the mid portion of described screw 4 is placed in card trepanning 4 and freely up and down can move along card trepanning 4.
The upper end of described screw 2 is provided with a plastic cap 3, and the other end of described screw 2 is provided with screw thread, described
The interlude of screw 2 is shiny surface, and the interlude of described screw 2 can move up and down in card trepanning 4, but screw 2
Plastic cap 3 sections and thread segment cannot pass through card trepanning 4, and so, screw 2 would not drop from cutting ferrule 1, it is possible to achieve specific
Cutting ferrule 1 purpose supporting with fixing screw 2.
Described anti-short-circuiting bar other parts in addition to plastic cap 3 all have metal material to make, described metal material include from
In be followed successively by basic unit, copper plate, tin coating to outward, described basic unit is preferably alloy material.Described copper plate, tin coating are not only
The effect with enhancing electric conductivity also has anti-corrosion, etch-proof effect, so can ensure that the electrical property of anti-short-circuiting bar
Can also strengthen the service life of anti-short-circuiting bar.
Preferably, the thickness of described copper plate is 2.5～4.0 μm, and the thickness of described tin coating is 3.0～6.0 μm.Described
Copper plate, tin coating can strengthen the electric conductivity of connection strap, and have effect antirust, erosion-resisting.
The anti-short-circuiting bar of one provided this utility model embodiment above is described in detail, used herein
Principle of the present utility model and embodiment are set forth by specific case, and the explanation of above example is only intended to help reason
Solve core concept of the present utility model；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model and side
Method, the most all will change, and in sum, it is right that this specification content should not be construed as
Restriction of the present utility model.
