Abstract
The utility model provides a detachable electrode sensor for a scanning electron microscope. The detachable electrode sensor comprises an electrode sensor head part, a conductive base and an electrode stem, wherein a thread cavity is formed in the electrode sensor head part, and thread bulges are arranged at the front ends of the conductive base and the electrode stem which are corresponding to the electrode sensor head; the electrode sensor head part comprises an electrode core body and an electrode jacket, and the electrode core body is packaged in the thread cavity; metal ejector pins with springs are arranged at the front ends of the conductive base and the electrode stem and connected with the electrode core body, and a binding post is arranged at the tail end of the electrode stem. The electrode head part has electrical conductivity through the conductive base with a thread so as to be observed by the scanning electron microscope. Through the thread bulges, the electrode head is conveniently dismounted, the sealing performance of an interface is improved, and the effective length of an electrode observation part is shortened, so that the electrode observation part is conveniently put in the narrow observation room of the scanning electron microscope to observe. In the premise, the conductive effect is effectively improved.
Description
Technical field
The utility model relates to a kind of electrode, relates in particular to a kind of scanning electron microscope detachable electrode sensor.
Background technology
In chemistry, biological experiment, along with improving constantly of electrode request for utilization, electrode after modification need to be used scanning electron microscope to go to characterize, and observation ward's limited space of scanning electron microscope, this has just proposed new requirement to the length of electrode, electrode length is long just cannot be put in the observation ward of scanning electron microscope and sample itself also must have electric conductivity, but electrode hermetically sealed case is corrosion resistant insulating material, after wrapping electrode core body, there is no electric conductivity, so just cannot carry out normal scanning electron microscopic observation.
Utility model content
According to above technical matters, the utility model proposes a kind of scanning electron microscope detachable electrode sensor, electrode head is dismantled by the metal threaded electrode head that facilitates of electrode stem projection, the effective length that has reduced electrode look-out station is convenient to put into the observation ward that scanning electron microscope is narrow and small and is observed, and the conductive seat with protruding metal screw thread makes the non-conductive electrode head that can not carry out scan electrode observation originally have electric conductivity, thereby can carry out scanning electron microscopic observation, and by effectively having improved again interface sealing and conductive effect under the metal threaded prerequisite facilitating electrode head dismounting, reduced resistance value, and tail wiring post is that gold-plated binding post has reduced the impact of corrosion on conductive effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows: a kind of scanning electron microscope detachable electrode sensor, comprise electrode sensor head, conductive seat and electrode stem, in described electrode sensor head, be provided with thread cavity, the described conductive seat corresponding with it and the front end of described electrode stem are all provided with thread protrusion, described electrode sensor head comprises electrode core body and electrode jacket, described electrode core body is encapsulated in described thread cavity, described conductive seat is connected with electrode core body with the metal thimble that electrode stem front end is all provided with spring, described electrode stem tail end is provided with binding post.
As preferably, described electrode stem comprises electrode jacket and inner lead.
As preferably, described binding post is gold-plated binding post, has reduced the impact of corrosion on conductive effect.
As preferably, described thread protrusion is metal threaded projection, has improved interface sealing and conductive effect, has reduced resistance value.
The utility model is dismantled by the metal threaded electrode head that facilitates of projection, the effective length that has reduced electrode look-out station is convenient to put into the observation ward that scanning electron microscope is narrow and small and is observed, screwed conductive seat makes the non-conductive electrode head that can not carry out scan electrode observation originally have electric conductivity, thereby can carry out scanning electron microscopic observation, and by effectively having improved again interface sealing and conductive effect under the metal threaded prerequisite facilitating electrode head dismounting, reduced resistance value, and tail wiring post is that gold-plated binding post has reduced the impact of corrosion on conductive effect.
