Abstract
An electrode for a cathodic protection device that has one or more electrode bodies formed of a conductive wire. The electrode includes a pair of films made of an insulating material which are bonded to each other while sandwiching the electrode body therebetween. Preferably at least one of the pair of films is bonded to an engine body. The electrode body is exposed to the outside through one or more through-holes formed in at least one of the films. The electrode is less susceptible to short-circuiting or wire breakage when bent and is also easier to manufacture than conventional electrodes.
Claims20
An electrode for a cathodic protection device, the electrode being configured to be immersed in water and connected to a power source, the electrode comprising:
- an electrode body formed from a conductive wire;
- and
- a pair of films made of an insulating material and bonded to each other while sandwiching the electrode body therebetween, at least one of the pair of films having at least one opening extending therethrough to expose at least a portion of the electrode body.
An electrode configured to be immersed in coolant water and connected to a power source, comprising:
- a first insulating film portion;
- a second insulating film portion, at least a part of the second insulating film portion being bonded to at least part of the first insulating film portion, the second insulating film portion having at least one opening;
- and
- at least one conductive wire disposed between the first and second insulating film portions so that at least a portion of the conductive wire is exposed through the at least one opening when the first insulating film portion is bonded to the second insulating film portion.
A marine engine comprising;
- a coolant passage configured to flow coolant;
- an electrode configured to be immersed in the coolant and connected to a power source, the electrode having a conductive wire, a first insulating portion, a second insulating portion bonded to the first insulating portion, and at least one opening;
- and
- wherein the conductive wire is disposed between the first and second portions so that at least a portion of the conductive wire is exposed through the at least one opening.
