Problems solved by technology
This structure is very prone to the problem of platinum needle loosening during use
After analysis, there are two main reasons. First: the stainless steel thin-walled tube will partially rebound after rolling, so it is not really compressed; second: the platinum material is soft and easy to deform. Plastic deformation occurs under impact, thereby loosening from the stainless steel thin-walled tube

The invention discloses a structural scheme of a pure platinum needle water electrode with high connection and sealing reliability and a manufacturing method thereof. One end of the stainless steel insert of the water electrode is an electrode terminal, and this end is extended from the end face to the inside to be provided with an electrode connection hole; the other end is a platinum needle installation end, and this end is provided with a threaded hole for pressing and fixing the platinum needle. The platinum needle is inserted into the inner hole of the stainless steel stopper, and the platinum needle is pressed together by the stopper and the installation end of the platinum needle of the stainless steel insert; the compression gasket has an inverted wedge-shaped structure after pre-installation, and it has a structure after the electrode body is overmolded. Anti-loosening effect, and can ensure reliable sealing of injection molding during lagging. The internal O-ring is on the joint surface of the stainless steel insert and the electrode body, which has the function of further improving the waterproof sealing effect; the water electrode is obtained by the method of overmolding the electrode body. The invention has the characteristics of high reliability of connection and sealing, and can ensure the excellent electrical contact performance and sealing performance of the water electrode under long-term use.
Description
Technical field[0001]The present invention relates to a structural solution and method for producing a highly linked and sealing reliability pure platinum needle, which belongs to the technical field of platinum needle water electrode.Background technique[0002]In a cooling system of some high voltage power devices, in order to clamp the potential difference of the cooling liquid, it is necessary to provide a water electrode to ensure that the coolant is equal to different positions of different positions. Metal platinum is an excellent water electrode material because it has very excellent electrochemical inertia. Typically reduce costs, stainless steel platinum plated as electrode part materials. However, for some applications with high requirements, pure platinum is still required for electrode materials for water electrodes.[0003]At present, the water electrodes of pure platinum typically processes one end tube at one end of the stainless steel electrode body, and the platinum ne...
