The embodiment of the present application provides a kind of contact material corrosion test tool, solves that there is presently no one kind to make
Contact material is the reliable and stable test instrument being in again under high current by clamping force, the skill for causing test to be difficult to carry out
Art problem.The embodiment of the present application also provides a kind of contact material corrosion test systems.
Below with reference to Fig. 1 to 2, a kind of contact material corrosion test tool provided by the embodiments of the present application is illustrated.
The contact of disconnecting switch generally includes moving contact and static contact.In disconnecting switch closure, moving contact and static contact
Between would generally be in close contact in the effect of the clamp systems such as spring, have very big clamping force between dynamic/static contact.And for touching
When the corrosion test of head material, the stress condition of contact material sample 8 can impact corrosion test, more to be there is reference
The test data of value needs to be in contact material sample 8 under similar clamping force effect.In addition it is also necessary to guaranteeing to pacify
In the case where complete, contact material sample 8 is made to bear high current.
Contact material corrosion test tool provided by the embodiments of the present application includes the first cleat insulator and the second insulating blanked clamper
Plate.Two pieces of cleat insulators are oppositely arranged, and therebetween for clamping contact material sample 8, certainly, are also used for clamp assay power supply 0
Contact (i.e. the first contact 9 and the second contact 7).
It, can be in such a way that screw rod 1 and tightening nut 2 cooperate when realizing the clamping between two pieces of cleat insulators.Specifically
, the through-hole passed through for screw rod 1 can be set on the first cleat insulator, and the second cleat insulator should also be as at same position
Through-hole is set, is consistent with the first cleat insulator.In this way, screw rod 1 can be each passed through the through-hole on the first cleat insulator with
And the second through-hole on cleat insulator corresponding position, form the frame of clamping structure.
Matched tightening nut 2 should be also arranged in the both ends of screw rod 1, and tightening can also set between nut 2 and cleat insulator
Set spring shim 5.
The quantity of screw rod 1 should be consistent with the quantity of through-hole on the first cleat insulator or the second cleat insulator, specific real
Now, two screw rods 1 can be set, three or four screw rods 1 also can be set, as long as the quantity of screw rod 1 is greater than or equal to two
Item is feasible.Certainly, correspondingly, through-hole will also match with the quantity of screw rod 1 on the first cleat insulator or the second cleat insulator
Set.
For example, through-hole can be set in the two sides of the first cleat insulator if the clamping structure of two screw rods 1 of setting, in this way,
For through-hole after penetrating screw rod 1, the space between two parallel screws 1 can be used for clamping contact material sample 8.And for contact material
Expect sample 8, stress can be adjusted by being symmetricly set on the screw rod 1 of two sides, so that stress be avoided to deviate, realize stress
It is balanced.
Similar, the number of openings no matter being arranged on the first cleat insulator or the second cleat insulator is how many, to guarantee
First cleat insulator and the second cleat insulator are supplied to the clamping force of the contact material sample 8 face contact material sample on direction
8 (i.e. vertical two pieces of cleat insulators), the through-hole being arranged on the first cleat insulator or the second cleat insulator should form isosceles three
The symmetrical shape such as angular, rectangle.
In the embodiment of the present application, clamping structure includes three screw rods 1 parallel to each other.Specifically, can be first
Three through-holes are set on cleat insulator, and three through-holes constitute isosceles triangle, the second cleat insulator and the first insulation in position
The identical setting of clamping plate, three screw rods 1 pass through the through-hole on two pieces of cleat insulators and form clamping structure.Three screw rods 1 and two pieces are absolutely
The triangular prism space that edge clamping plate is formed can be used for being arranged contact material sample 8, and three screw rods 1 will not be to contact material sample 8
It is formed and is hindered.
Further, insulating support rod 6 can also be set, the isosceles triangle formed between the through-hole of the first cleat insulator
Interior, setting and the matched supported hole of insulating support rod 6, the second cleat insulator are equally arranged.In this way, in test, insulating supporting
Bar 6 can sequentially pass through the first cleat insulator, the first contact 9 of experiment power supply 0, multiple contact material samples stacked together
8, the second contact 7 and the second cleat insulator of experiment power supply 0 realizes positioning and the contact material sample of contact material sample 8
Contraposition between product 8 keeps the contact area between contact material sample 8 as identical as possible.
It is appreciated that insulating support rod 6 is when in use, the first contact 9 and the second contact 7, contact material of experiment power supply 0
Sample 8 should all open up corresponding hole location, so that insulating support rod 6 passes through.
It is preferably disposed at the center in isosceles triangle with the matched supported hole of insulating support rod 6, it is of course also possible to set
Set non-central position in isosceles triangle.But when centrally disposed, the axis of clamping structure is arranged in insulating support rod 6,
More convenient when test instrument and contact material sample 8 assemble, the contraposition effect between contact material sample 8 is also more preferable.
Insulating support rod 6 can select the material of epoxy glass laminate, have enough intensity, while can also block electricity
Stream, cannot pass through electric current, does not influence the corrosion kinetics of etching system.
Further, it is contemplated that often rigidity is inadequate for insulating materials, when screw rod 1 is tightened, the first cleat insulator and second
The stress of cleat insulator is very big, is easily damaged.Therefore, cleat insulator can be arranged to double-layer structure, including insulating layer 3 with by
The inside of clamping structure is arranged in two layers of power layer 4, the insulating layer 3 for playing insulating effect, and the stress layer 4 for playing transmitting pressure is arranged
On the outside, it is directly contacted with tightening nut 2, to cleverly be enhanced under the premise of not influencing cleat insulator insulation performance absolutely
The intensity of edge clamping plate.
The daughter board specifically, insulating layer 3 can be insulated with PVC, stress layer 4 can be stainless steel substrates.
The clamping force that contact material sample 8 is subject to is just or slightly to deviate, and mainly observes by the naked eye tightening nut 2
Position judge, it is clear that the judgement of naked eyes is not accurate enough.Therefore, first pressure sensor and the second pressure can be set
Force snesor.
First pressure sensor and second pressure sensor should be arranged in the first cleat insulator and the second cleat insulator it
Between, it is parallel with each screw rod 1.The contact point of first pressure sensor and the first cleat insulator can be known as first contact point, the
The contact point of two pressure sensors and the first cleat insulator is known as the second contact point.Then first contact point can be made to contact with second
Point on the symmetry axis of isosceles triangle, also, two contact points should with respect to the central symmetry of isosceles triangle, so as to
To judge what contact material sample 8 was subject to by comparing the pressure value between first pressure sensor and second pressure sensor
It is symmetrical at left and right sides of clamping force.
