It is relevant etc. factor.Contact resistance and contact are in inverse relationship, and contact is to contraction protein value and surface electric resistance value
Influence is maximum.
Disconnecting link contact force on existing market, the main bayonet lock using stationary contact in itself, the deformation within elastic limit,
To increase its pressure.For high current disconnecting link, generally require to increase its stationary contact dot thickness, reduce its folder spring bending arc length or extra
Rivet welding presss from both sides spring.This allows for material cost, processing cost and risen.
Utility model content
In view of the shortcomings of the prior art, the utility model proposes a kind of connect-disconnect structure of high current, wedge-shaped inner chamber is used
Structure, is promoted using the stroke of movable contact, makes sound contact combination pressure sufficiently large, so as to reduce the resistance of contact point.
To realize above-mentioned technical proposal, the utility model provides a kind of connect-disconnect structure of high current, including：Movable contact is inserted
Piece, wedge mount, stationary contact hook switch and fixed seat, the movable contact inserted sheet are fixed on wedge mount, and the wedge mount lower end is symmetrical
Two projections are provided with, the projection inwall is gradually tapered up upwards, the relative inner side of described two projections is formed gradually receives upwards
The conical cavity of contracting, movable contact inserted sheet runs through the center of the conical cavity, and the stationary contact hook switch is fixed in fixed seat, described quiet
Contact hook switch includes cavity kink, resilient clamp portion and folding ear, and the cavity bending part is in the lower end of stationary contact hook switch
And be connected with fixed seat, resilient clamp portion is located above cavity kink, and folding ear is located at resilient clamp portion top, and movable contact is inserted
The resilient clamp portion that piece can be inserted into stationary contact hook switch, folding ear contacts with projection inwall.
In the above-mentioned technical solutions, using this connect-disconnect structure, the elastic clip that movable contact inserted sheet is inserted in stationary contact hook switch
When holding portion, wedge mount is moved downwardly together with movable contact inserted sheet, in the projection for rolling over ear and wedge mount in stationary contact hook switch
Wall is contacted, and because projection inwall is gradually tapered up upwards, as the distance that wedge mount is moved downward is bigger, projection inwall will roll over ear
That inwardly compresses is tighter, so drive that resilient clamp portion clamp to movable contact inserted sheet it is tighter so that reduce movable contact inserted sheet and
Resistance between stationary contact hook switch, is easy to electric current to pass through.Simultaneously as be taper-face contact between wedge mount and stationary contact hook switch,
Therefore when wedge mount is extracted upwards, stationary contact hook switch will not cause resistance to the extraction of wedge mount, facilitate wedge mount and dynamic tactile
The extraction of point inserted sheet.
It is preferred that, the movable contact inserted sheet and stationary contact hook switch are copper material, and the resistance of copper material is low, and during bending
Elasticity and rigidity it is preferable, be especially suitable for make this connect-disconnect structure in movable contact inserted sheet and stationary contact hook switch.
It is preferred that, the wedge mount is plastics or quality of rubber materials, the low easy processing of plastic material price, good, the rubber of rigidity
The insulating properties of material are high.
A kind of beneficial effect of the connect-disconnect structure for high current that the utility model is provided is：The connect-disconnect structure of this high current
Ingenious in design, making is easy, simple in construction, by the conical cavity on wedge mount resilient clamp portion can be caused to movable contact inserted sheet
What is clamped is tighter, so that the resistance between movable contact inserted sheet and stationary contact hook switch is reduced, while nor affecting on movable contact inserted sheet
Extract.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.The every other embodiment that this area ordinary person is obtained under the premise of creative work is not made, is belonged to
Protection domain of the present utility model.
Embodiment：A kind of connect-disconnect structure of high current.
It is shown referring to Figures 1 and 2, a kind of connect-disconnect structure of high current, including：Movable contact inserted sheet 10, wedge mount 20, stationary contact
Point hook switch 30 and fixed seat 40, the movable contact inserted sheet 10 are fixed on wedge mount 20, and the lower end of wedge mount 20 is symmetrical arranged
There are two projections 22, the inwall of projection 22 is gradually tapered up upwards, the relative inner side of described two projections 22 is formed upwards gradually
The conical cavity 21 of contraction, movable contact inserted sheet 10 runs through the center of the conical cavity 21, and the stationary contact hook switch 30 is fixed on fixation
On seat 40, the stationary contact hook switch 30 includes cavity kink 31, resilient clamp portion 32 and folding ear 33, the cavity kink
31 are located at the lower end of stationary contact hook switch 30 and are connected with fixed seat 40, and resilient clamp portion 32 is located at the top of cavity kink 31, folding
Ear 33 is located at the top of resilient clamp portion 32, the resilient clamp portion 32 that movable contact inserted sheet 10 can be inserted into stationary contact hook switch 30, folding
Ear 33 contacts with the inwall of projection 22.
Operation principle of the present utility model is：Using this connect-disconnect structure, movable contact inserted sheet 10 is inserted into stationary contact hook switch 30
In resilient clamp portion 32 when, wedge mount 20 is moved downwardly together with movable contact inserted sheet 10, the folding ear in stationary contact hook switch 30
Portion 33 is contacted with the inwall of projection 22 of wedge mount 20, because the inwall of projection 22 is gradually tapered up upwards, as wedge mount 20 is transported downwards
Dynamic distance is bigger, and the inwall of projection 22 is tighter by roll over that ear 33 inwardly compresses, and then drives resilient clamp portion 32 to movable contact
It is tighter that inserted sheet 10 is clamped, so as to reduce the resistance between movable contact inserted sheet 10 and stationary contact hook switch 30, is easy to electric current to pass through.Together
When, due to being taper-face contact between wedge mount 20 and stationary contact hook switch 30, therefore when wedge mount 20 is extracted upwards, stationary contact fork
Spring 30 will not cause resistance to the extraction of wedge mount 20, facilitate the extraction of wedge mount 20 and movable contact inserted sheet 10.
In the present embodiment, the movable contact inserted sheet 10 and stationary contact hook switch 30 are copper material, and the resistance of copper material is low, and
And the elasticity and rigidity during bending are preferable, are especially suitable for making the movable contact inserted sheet 10 and stationary contact hook switch in this connect-disconnect structure
30。
In the present embodiment, the wedge mount 20 is plastic material, the low easy processing of plastic material price, good, the insulating properties of rigidity
Can be high.
It is described above be preferred embodiment of the present utility model, but the utility model should not be limited to the embodiment and
Accompanying drawing disclosure of that, so every do not depart from the lower equivalent or modification completed of spirit disclosed in the utility model, all falls
