Abstract
Description
Technical Field
[0001] This utility model relates to the field of bioelectric signal measurement technology, specifically a silver-silver chloride electrode with stable silver wire connection. Background Technology
[0002] Silver-silver chloride electrodes are currently the most potentically stable electrodes used in electrochemical measurements and body surface electrical signal detection. However, silver chloride is also a strong oxidizing agent; when it encounters metals and electrolytes, it corrodes the metals while being reduced to silver, thus losing the excellent performance of the silver-silver chloride electrode. A silver / silver chloride reference electrode typically consists of a shell, electrolyte, silver-silver chloride electrode, lead wires, and a liquid junction. The electrolyte is usually a potassium chloride solution of a certain concentration. Since the potential is a function of the concentration of chloride ions on and around the electrode surface, when the electrolyte concentration remains constant, the concentration of chloride ions on the electrode surface remains constant, thus maintaining potential stability.
[0003] The existing silver-silver chloride electrode is prone to shaking during use due to its simple installation structure, which affects the accuracy of experimental records. Utility Model Content
[0004] The purpose of this invention is to provide a silver-silver chloride electrode with stable silver wire connection, solving the problem mentioned in the background art that existing silver-silver chloride electrodes are prone to shaking during use due to their simple installation structure, thus affecting the accuracy of experimental records. To achieve the above objective, this invention provides the following technical solution: a silver-silver chloride electrode with stable silver wire connection, comprising an insulating shell, a wire sleeved inside the insulating shell, a sealing ring fixedly connected to the bottom of the insulating shell, a connecting seat fixedly connected to one side of the sealing ring, a rubber protective sleeve fixedly connected to the bottom of the connecting seat, and a sleeve fixedly connected to the bottom of the rubber protective sleeve. The wire extends through the sleeve to the bottom of the sleeve. The sealing ring connects the insulating shell and the connecting seat. Simultaneously, the sealing ring has high wear resistance, ensuring that the electrolyte will not leak under long-term operation and high pressure, thus preventing changes in the electrode inside the shell and improving the practicality of the device.
[0005] More preferably, a connecting chamber is fixedly connected inside the insulating shell, a platinum wire is fixedly connected to the bottom of the conductor, a material layer is fixedly connected to the bottom of the connecting chamber, and the platinum wire penetrates and connects inside the material layer. By installing the connecting chamber, the electrode can be placed in the connecting chamber and connected to the electrode by the platinum wire penetrating and connecting inside the material layer. By injecting electrolyte into its interior, the stability of the electrode is ensured.
[0006] More preferably, a top cover is fixedly connected to the top of the insulating shell. The upper surface of the top cover has holes, and an anti-corrosion layer is provided on the outside of the top cover. By installing the top cover and then placing the device in the electrolyte, the electrolyte enters the interior of the device through the holes for electrode use. At the same time, the anti-corrosion layer on the outside of the top cover not only improves the device's corrosion resistance and durability, but also improves the device's efficiency and extends its service life.
[0007] More preferably, the outer wall of the insulating shell is fixedly connected to a liquid replenishment port, and a rubber cap is fixedly connected to the outer wall of the liquid replenishment port. By installing the liquid replenishment port, electrolyte can be replenished into the insulating shell through the replenishment port to prevent the electrode potential from shifting or becoming unstable due to changes in the concentration of the electrolyte, thereby ensuring the use of the electrode.
[0008] More preferably, an electrode is fixedly connected inside the insulating shell, and a wire is fixedly connected to the top of the electrode. The electrode is fixedly installed inside the connection chamber. By installing the electrode, the response of the electrode can be recorded during use, so that the changing potential in electrochemical analysis can be quickly understood.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] In this invention, a sealing ring is installed to connect the insulating shell to the connecting seat. The sealing ring is highly wear-resistant, ensuring that the electrolyte will not leak under long-term operation and high pressure, thus preventing changes in the electrodes inside the shell and improving the practicality of the device.
[0011] In this invention, by installing a top cover, the device is placed in an electrolyte solution, and the electrolyte solution enters the interior of the device through the holes for electrode use. At the same time, an anti-corrosion layer is set on the outside of the top cover, which not only improves the device's corrosion resistance and durability, but also improves the device's efficiency and extends its service life.
