As the configuration includes a terminal plate 8 to which the wire 30 is connected, the dew condensation sensor can be fixed by pressing the terminal side provided on the dew condensation sensor toward the mounting member, and the operation of attaching the dew condensation sensor to the mounting member is possible. This method eliminates the above-mentioned drawbacks by making it possible to perform the steps with a single touch, and will be explained in detail below using examples.

1 to 4 are simplified configuration diagrams showing an embodiment of a dew condensation sensor mounting device according to the present invention,
In the figure, a dew condensation sensor S attached to a mounting member F such as a windshield has a transparent substrate 3, a linear electrode 1 provided on the surface side of this substrate 3 by means such as vapor deposition, and an end of this electrode 1. The terminals 2 are located opposite to both ends of the substrate 3. 4, 4 are mounting frames that hold both ends of this dew condensation sensor S, and these mounting frames 4, 4 are provided on the upper plate 5 located above the terminals 2, 2, and on the sides of this upper plate 5. It is composed of a side plate 6 and a bottom plate 7, and has a box shape that covers the top and side sides at both ends of the dew condensation sensor S. On the inner side of the bottom plate 7, a terminal plate 8 is vertically arranged. At the upper end of this terminal plate 8, a protrusion 9 is provided which protrudes horizontally from the bottom plate 7 side along the inner surface of the upper plate 5.
The opposite side of the terminal plate 8 from the protruding portion 9 protrudes outward from the bottom plate 7, and a lead wire 30 or the like is connected to this protruding portion by caulking, soldering, or the like. A notch 10 that opens toward the center of the dew condensation sensor S is provided at a location corresponding to the terminal 2 on the upper plate 5.
A rotary lid plate 11 that can freely rotate in the vertical direction is attached to the. This rotating cover plate 11 is located on the bottom plate 7 side, and is provided with a shaft 12 bridging the notch 10.
1 rotates in the vertical direction using this shaft 12 as a fulcrum. A convex portion 14 is provided on the side wall of the rotary cover plate 11, and this convex portion 14 fits into a recess 13 formed on the side wall side of the notch 10 to lock the cover plate 11 in the horizontal direction. constitute the department. On the surface of the cover plate 11 that faces the terminal 2 from the shaft 12 side, there is a curved portion 15 that extends in the terminal 2 direction and then deforms and curves in the opposite direction, and a curved portion 15 extending in the rear direction from the rear end side of the upper plate 5. An elastic contact piece 16 made of phosphor bronze or the like comprising a protruding convex portion 17 is attached by means such as a screw (not shown), and the curved portion 1 of this contact piece 16
As shown in FIG. 3, when the cover plate 11 is horizontally locked by the convex portion 14 as a locking portion, the upper side of the terminal 2 is pressed and contacted to fix the dew condensation sensor S and the convex portion 17 comes into contact with the lower surface of the protruding portion 9 of the terminal board 8 and functions to guide the signal from the terminal 2 to the terminal board 8 side.

According to the above configuration, when the dew condensation sensor S is attached to the mounting member F side such as a windshield, the mounting frame 4 is attached in advance to a predetermined position using adhesive or double-sided tape, and in this state, the rotating cover plate is attached. 11 is rotated upward to unfold it, and after positioning the dew condensation sensor S on the mounting member F through the notch 10, the rotary cover plate 11 is rotated downward and locked in the horizontal direction. As a result, the curved portion 1 of the contact piece 16
5 is in pressure contact with the surface side of terminal 2, so the condensation sensor S
Both ends are pressed against the mounting member F and fixed.
Further, a signal from the terminal 2 can be guided toward the terminal plate 8 via the contact piece 16, and the signal can be detected from the terminal plate 8 via the lead wire 30. Further, when replacing the dew condensation sensor S, the rotary cover plate 11 may be rotated to take it out and attach it.

According to this embodiment, since the dew condensation sensor S can be easily set by operating the rotary cover plate 11, installation is simple and replacement can be performed smoothly.Furthermore, the mounting frame 4 itself is formed of an opaque material. If this is done, the adhesive for bonding the mounting frame 4 to the mounting member F will not be visible, and the appearance can be improved.

In addition, in the embodiment, the mounting frames 4, 4
Although described as being independent from each other, at least the side plate 6 side may be integrated with each other. Alternatively, ventilation holes may be provided in this integrated side plate 6. Further, the contact piece 16 may be made of conductive rubber or the like instead of using a material such as phosphor bronze.

As explained above, according to the present invention, a mounting frame is provided which is located at least on the upper side of the end of the dew condensation sensor, a lid plate that rotates vertically with respect to the mounting frame is provided, and the lid plate is provided with the dew condensation sensor. Since the pressing member that presses against the side is provided, the dew condensation sensor can be easily attached and replaced. Further, since there is no need to attach the dew condensation sensor using adhesive or the like, the appearance can be improved.
