Description

A kind of electro-chemical test fixture
Technical field
This utility model relates to a kind of electro-chemical test experimental provision, concretely relates to a kind of electro-chemical test fixture.
Background technology
At present, electrochemistry experiment sample mainly passes through at test piece back side welding lead, and uses epoxy resin or other electrically non-conductive material that the region being not intended to expose is carried out covering sealing.There is following problem in this method: 1. the heat of wire welding may produce impact to sample.2. rustless steel is not easy soldering.3. use resin seal to need solidification, take time and effort.4. easily produce gap between resin and sample, cause solution to enter.5. the distance between sample and electrode is not fixed.
The patent No. 201520236495.8 discloses a kind of electro-chemical test specimen holder, but there is following problem: 1. fixture and sample are without sealing ring, fixture is relied on to realize sealing with the extruding of specimen surface, in installation process, sample groove is susceptible to deformation, cause outer surface can not fit tightly with sample groove, it is easily caused liquid to enter, makes the test area of sample change, and then affect experimental result.2. wire relies on to threaded with sample and extrudes laminating, is susceptible to loose contact during use.3. the requirement on machining accuracy of pair fixture is high.4. do not consider the relative position between sample with electrode.
Utility model content
Based on above-mentioned technical problem, this utility model provides a kind of electro-chemical test fixture.
The technical solution that this utility model is used is:
A kind of electro-chemical test fixture, including wire, insulating bar and electrode, mesopore is offered at the center of insulating bar, described wire passes from the mesopore of insulating bar, one end of wire connects spring thimble, one end of insulating bar connects base, base is provided with the groove for placing sample, one end of base is provided with gland, and after base is connected with gland, sample is pressed in groove by gland, now spring thimble is in close contact with sample, offering circular hole on gland, test medium is each attached on fixation clamp through circular hole and sample contacts, insulating bar and electrode.
Preferably, described insulating bar is connected with whorl of base, and base is threadeded with gland, is provided with sealing ring between sample and base and between sample and gland.
Preferably, described insulating bar and electrode are the most vertically fixed on fixation clamp, and the lower horizontal bending of insulating bar, described base is connected to the bottom of insulating bar, and the bottom of electrode connects Luggin capillary.
Advantageous Effects of the present utility model is:
This utility model electro-chemical test fixture has sample and installs simple and fast, it is not necessary to welding lead and resin seal, seals off and be conductively connected reliable, the advantages such as efficiency is high, cost-effective.And can the mounting distance of fixed electrode and sample, decrease interference factor, the comparability of experimental result is higher.
Accompanying drawing explanation
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
In figure: 1. wire, 2. insulating bar, 3. base, 4. gland, 5. spring thimble, 6. sample, 7. fixation clamp, 8. electrode, 9-Luggin capillary.
Detailed description of the invention
In order to improve electrochemistry experiment efficiency, saving sample cost, improve stability and repeatability, this utility model provides a kind of electro-chemical test fixture, and this fixture can realize the most fixing, communication conductive wire and the isolation test medium of sample.The operations such as the welding lead and the resin seal that eliminate sample.Specifically: this utility model realizes wire and outside insulation by insulant, conduction quickly it is connected by what spring thimble realized sample and wire.Realized the connection of each several part by screw thread, realized the control of sample exposed area by the perforate on gland, realize sealing by compressing sealing ring so that the internal isolation with external agency.It is described in detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of electro-chemical test fixture, including wire 1, insulating bar 2 and electrode 8, offering mesopore at the center of insulating bar 2, described wire 1 passes from the mesopore of insulating bar.One end of wire 1 connects spring thimble 5, one end of insulating bar 2 connects base 3, it is provided with the groove for placing sample on the base 3, one end of base 3 is provided with gland 4, after base 3 is connected with gland 4, sample is pressed in groove by gland 4, and now spring thimble 5 is in close contact with sample under the effect of elastic force.Offering circular hole on gland 4, test medium, through circular hole and sample contacts, realizes the control of sample exposed area by the big I of the circular hole on gland.Insulating bar 2 and electrode 8 are each attached on fixation clamp 7.Distance between fixation clamp 7 adjustable, insulating bar 2 and electrode 8.
As to further design of the present utility model, described insulating bar 2 is threaded connection with base 3, and base 3 is threaded connection with gland 4, is provided with sealing ring between sample 6 and base 3 and between sample 6 and gland 4.
Further, described insulating bar 2 and electrode 8 are the most vertically fixed on fixation clamp 7.The lower horizontal bending of insulating bar 2, described base 3 is connected to the bottom of insulating bar 2, and the bottom of electrode 8 connects Luggin capillary 9.
The installation of this utility model electro-chemical test fixture and use approximately as:
