Figure 4 is a bottom view showing the pressure cover portion of the leak sensor case according to an embodiment of the present invention, and Figure 5 is an exemplary view for explaining the clamp of the leak sensor case according to an embodiment of the present invention.

Hereinafter, the description will further include FIGS. 4 and 5.

The pressing protrusion 314 may be formed to protrude from the central portion of the lower portion 313 of the cover body portion 310. When the pressure cover part 300 is coupled to the base part 100, the pressure protrusion 314 may press one end of the leak sensor 10 into which the electrode part 200 is inserted. The pressure protrusion 314 may be formed to have a width corresponding to the width of the electrode portion 200, and through this, the leak sensor 10 can effectively pressurize the area corresponding to the electrode portion 200 in the leak sensor 10. It can be prevented from falling out of the electrode unit 200.

In addition, as described above, since the cushion portion 400 is formed of an elastic material, when the pressing protrusion 314 presses one end of the leak sensor 10, the leak sensor 10 and the electrode portion 200 It can be adhered more stably.

The clamps 320 may be provided as a pair on the lower part 313 of the cover body 310. A mounting groove 316 may be formed in the lower part 313 of the cover body 310 to allow the clamp 320 to be inserted. The clamp 320 may press one end of the leak sensor 10, more specifically, the side area 16 while the leak sensor 10 is connected to the electrode unit 200. The clamp 320 may have a plurality of clamping protrusions 321 at its lower portion. Since the sensing element 15 may not be provided in the side area 16, the clamping protrusion 321 may have a sharp lower end so as to penetrate the film strap 11. Through this, the clamp 320 can press the side area 16 with a stronger force and fix the leak sensor 10 more firmly.

The clamping protrusion 321 may be formed to protrude at a height lower than the thickness of the leak sensor 10. Through this, the clamping protrusion 321 can stably pressurize the leak sensor 10 even when the pressing cover part 300 and the base part 100 are combined.

Figure 6 is an exemplary diagram for explaining another example of a clamp of a leak sensor case according to an embodiment of the present invention.

As shown in FIGS. 2 and 6, the horizontal body portion 110 may have an insertion groove 117. The insertion groove 117 may be formed in the upper part of the horizontal body 110 on both sides of the seating groove 111. The insertion groove 117 may be formed at a position corresponding to the clamp 320. The insertion groove 117 may be formed to correspond to the lower shape of the clamp 320, and when the pressure cover part 300 is coupled to the base part 100, the insertion groove 117 has a clamping protrusion 321. can be inserted.

According to this embodiment, the clamping protrusion 321 may be formed to protrude at a height higher than the thickness of the leak sensor 10. Through this, even when the pressing cover part 300 and the base part 100 are combined, the clamping protrusion 321 can stably press the leak sensor 10 and generates a greater pressing force to press the leak sensor 10. can be fixed more strongly.

And, the pressure cover part 300 may have a second inclined part 315. The second inclined portion 315 may be formed at the front end of the cover body portion 310 and may be formed to correspond to the first inclined portion 114 of the horizontal body portion 110.

When the pressure cover part 300 is coupled to the base part 100 with the electrode part 200 inserted into one end of the leak sensor 10, the second inclined part 315 presses the leak sensor 10. As a result, the leak sensor 10 can be bent downward.

Figure 7 is an exemplary diagram for comparing the shape of a leak sensor according to an embodiment of the present invention and a conventional leak sensor case.

As shown in (a) of FIG. 7, in the leak sensor case according to the present invention, the leak sensor 10 may be bent downward between the first inclined portion 114 and the second inclined portion 315. Accordingly, the portion 10a of the leak sensor 10 that exits the front end of the base portion 100 may directly contact the object 20. The object 20 may be an object to be tested for leaks, for example, a pipe through which hazardous chemicals are transported. For example, when a crack 21 occurs in the object 20 and hazardous chemicals leak through the crack 21, the portion 10a exiting the front end of the base portion 100 is directly exposed to the object 20. When contacting (20), hazardous chemicals leaking from the part where the crack (21) occurs can be directly detected by the sensing element of the leak sensor (10), and thus the leak can be detected quickly and accurately.

On the other hand, as shown in (b) of FIG. 7, in the conventional leak sensor case 30, the leak sensor 10 extends in the horizontal direction, so the portion 10a exiting the front end of the leak sensor case 30 is It is impossible to directly contact the object 20. Therefore, the leak sensor 10 connected to the conventional leak sensor case 30 may take a long time to detect hazardous chemicals leaking from the crack 21. Furthermore, when the object 20 is installed outdoors or in a windy environment where the object 20 is installed, hazardous chemicals leaking from the crack 21 are detected by the detection element 15 of the leak sensor 10. Leakage of hazardous chemicals may not be detected as contact may not occur.

Figure 8 is a cross-sectional perspective view of the pressure cover portion of the leak sensor case according to an embodiment of the present invention.

As shown in FIGS. 2 and 8, the leak sensor case may include a reinforcement portion 500. When the pressure cover part 300 has a first rigidity, the reinforcement part 500 may have a second rigidity that is greater than the first rigidity. The reinforcement part 500 may be provided inside the pressure cover part 300, and preferably may be provided entirely in the pressure cover part 300. The reinforcement part 500 can reinforce the rigidity of the pressure cover part 300. When the pressure cover part 300 is coupled to the base part 100, the fastening member 312 is coupled to the base part 100 on both sides of the pressure cover part 300, and the leak sensor 10 is inserted in the center. Therefore, if the rigidity of the pressure cover 300 is weak, the pressure cover 300 may be deformed so that the center is convex upward. And in this case, the leak sensor 10 may not be sufficiently pressurized by the pressurizing cover unit 300.

The reinforcement part 500 can prevent deformation of the pressure cover part 300 by reinforcing the rigidity of the pressure cover part 300, and through this, the leak sensor 10 is sufficiently stable by the pressure cover part 300. It can be made to be pressurized.
