DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the construction of a leakage detection sensor according to a first embodiment of the present invention and modifications thereof will be described in detail with reference to the drawings.

FIG. 1 is a schematic exploded perspective view of a leakage detection sensor according to a first embodiment of the present invention, and FIG. 2 is a schematic perspective view of a leakage detection sensor according to a first embodiment of the present invention.

The leakage sensor according to an embodiment of the present invention may include a base unit 100, a conductive line 200, a cover unit 300, and a double-sided adhesive tape 500.

The leakage detection sensor includes a base part 100, a conductive line 200 arranged in pairs on the upper surface of the base part 100, a cover part 300 located on the upper side of the conductive line 200, The conductive line 200 may include a coating layer applied to the surface of the conductive line 200 to prevent corrosion and malfunction.

The conductive line 200 includes a main conductive line 210 in which two lines are arranged in the longitudinal direction of the base 100 and a plurality of sub conductive lines 220 protruding from the respective main conductive lines 210, . ≪ / RTI > The conductive line 200 includes a main conductive line 210 symmetrically disposed in the longitudinal direction of the base unit 100 and two conductive lines 210 symmetrically disposed inside the two main conductive lines 210 symmetrically disposed. And a plurality of sub-conductive lines 220 protruding from the main conductive line 210. The plurality of sub-conductive lines 220 protruding from the two main conductive lines 210 may be located at intersecting positions, have.

The base portion 100 may be formed of an insulator as a layer in which a conductive line 200 to be described later is disposed.

The conductive line 200 is a conductor arranged in a pair on the upper surface of the base portion 100. When the leakage of electricity occurs when electricity flows, the conductive line 200 becomes a short-circuited line, The conductive line 200 may include a primary transfer line 210 and a secondary transfer line 220.

Two main transfer liners 210 are arranged in the longitudinal direction of the base unit 100. One ends of the two main transfer liners 210 are connected to each other by a wire or the like to allow a current to flow. For example, as can be seen from the example of FIG. 1, the main transfer liners 210 may be positioned symmetrically with respect to each other in the longitudinal direction of the base portion 100.

The secondary transfer line 220 protrudes from the main transfer line 210, and a plurality of the secondary transfer lines 220 can be disposed to more accurately and quickly detect the leakage. For example, as shown in the example of FIG. 1, the sub-line 220 may protrude to the inside of the main conductive line 210 disposed symmetrically.

The intersection pattern of the sub-conductive lines 220 narrows the interval between the pair of the conductive lines 200 so that even if there is a leak or a small amount of leakage flowing in only one of the conductive lines 200, So that accurate leak detection can be enabled. In addition, the intersection pattern of the secondary transfer line 220 can serve to more accurately recognize the position of the leaked water passing through one sensing hole 400, which will be described later.

The coating layer is applied to the surface of the conductive line 200 and can prevent erosion and malfunction of the leak sensor. If the coating line is not coated, the conductive line 200 may react to contact with humidity, metal, metallic dust, human body, etc., and may malfunction even if the leakage is not actual leakage. . In addition, the coating layer can prevent corrosion of the conductive line 200 due to leakage of water or humidity, protect the conductive line 200, and enhance the durability of the conductive line 200.

The coating layer is not applied as a layer between the base portion 100 and the cover portion 300 but is coated only on the surfaces of the main conductive phosphor 210 and the sub conductive phosphor 220 which are the conductive lines 200, can do. For example, the coating layer may include a solution containing silver and palladium (Pd), and this solution has an effect of improving the leakage sensing function and preventing oxidation of the conductive line 200.
