Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral Up denotes an upper side, and reference numerals W1 and W2 denote a width direction. The vertical direction coincides with the gravity direction G.

Fig. 1 is a perspective view showing a vehicle interior.

An instrument panel 61 is provided in a vehicle compartment of an automobile. Various switch devices are disposed on the instrument panel 61. A laser lamp 62, an air conditioner switch 63, a shift switch 64, and a travel mode selection switch 65 are provided in the center portion of the instrument panel 61 from above.

The switch device 11 of the present embodiment can be applied to switches of a panel attached to a horizontal surface, and can be applied to the shift switch 64, the travel mode selection switch 65, the power window switch 69, and the power window switch 72.

The switch device 11 of the present embodiment can be applied to switches mounted on a panel of an inclined surface, and can be applied to the laser lamp 62, the air conditioner switch 63, and the engine switch 66.

Fig. 2 is a perspective view of the switching device 11. Fig. 3 is a side view showing the concept of the switching device 11. And fig. 4 is a sectional view taken along line IV-IV in fig. 3.

As shown in fig. 2, the switch device 11 includes an operation portion 12, a switch member 13, a housing 14, a connector portion 15, and a fixing portion 16.

The switch member 13 is disposed inside the housing 14. The fixing portions 16 are snap-fit fixing members, and are disposed on both sides of the housing 14 as shown in fig. 3. A through hole 81 is opened in the instrument panel 61, and the switch device 11 is press-fitted into the through hole 81 from the front surface side of the instrument panel 61. And the switch device 11 is fixed to the instrument panel 61 by a pair of fixing portions 16.

The switch device 11 is connected to the cable 30. The operation of the switch device 11 is transmitted to an in-vehicle device, not shown, via the cable 30.

A connector portion 15 is connected to the switch member 13. The connector portion 15 is formed integrally with the switch member 13.

In the present embodiment, the operation unit 12 is connected to the upper portion of the switch member 13, and the connector unit 15 is connected to the lower portion of the switch member 13.

The operation unit 12 may be provided on a side portion of the switch member 13, and the connector unit 15 may be provided on a lower portion of the switch member 13.

The cable 30 is connected to the connector portion 15.

The terminal 31 of the cable 30 is inserted into the connector portion 15, and the cable 30 is electrically connected to an unshown electrical contact of the switch member. The cable 30 is connected to an in-vehicle device or the like, not shown, and the operation of the switch device 11 is electrically taken out and transmitted to the in-vehicle device or the like via the cable 30.

The housing 14 covers the switch member 13 and covers a part of the connector portion 15. The opening and closing member 13 is disposed in the housing 14, and the opening and closing member 13 is integrally fixed to the housing 14. The outer peripheral portion 14a of the housing 14 surrounds the switch member 13, and surrounds the connection portion 15a of the connector portion 15 connected to the switch member 13.

The outer peripheral portion 14a has an open end 14d at a lower end. Outer peripheral portion 14a has 2 outer side surfaces 14b and 2 outer side surfaces 14 c. The outer side surface 14b is adjacent to the outer side surface 14c, and the fixing portion 16 is provided on the outer side surface 14 c. An open end 14d is formed by the lower end of the outer side surface 14b and the lower end of the outer side surface 14 c.

The housing 14 is formed such that the connector portion 15 is inserted into the opening of the opening end portion 14 d. A gap 17 is formed between the connector portion 15 and the housing 14.

At the opening end 14d, the connector portion 15 extends in the opening direction of the opening end 14 d. In the present embodiment, the opening end portion 14d is opened downward, and the connector portion 15 extends downward from the opening/closing member 13.

As shown in fig. 3 and 4, the open end 14d includes an edge 14e at the lower end of the outer surface 14b and an edge 14g of the outer surface 14 c. The edge portion 14e is provided over the entire width-directional region of the outer surface 14 b. The edge 14e is formed in an inverted V shape having a high central portion and a low side portion in the width direction. In the rim portion 14e, the highest position (1 st height position) is a position P1, and the lowest position (2 nd height position) is a position P2.

The position P2 appears on both sides of the edge 14e, at the same height. The edge 14g of the outer surface 14c is linear and has a constant height.

In the rim portion 14e, the shape between the position P1 and the position P2 is a linear shape inclined with respect to the gravitational direction G. The liquid adhering to the outer surface 14b of the housing 14 moves in the gravity direction G and is concentrated along the edge portion 14e to a position P2 provided at the side in the width direction.

By providing the opening end portion 14d with a portion for collecting the liquid adhering to the housing 14 in this way, the path of the liquid when the switch device 11 is in contact with water can be easily predicted, and measures against the liquid adhering to the switch device 11 can be easily taken.

As shown in fig. 4, a thickened portion 20 is formed at the opening end 14d of the housing 14. The thickened portion 20 is a shape of a lower end portion of the housing 14, and is a shape expanding outward of the housing 14 in the direction of gravity G. Thickened portion 20 is formed by the shape in thickness direction D of case 14. The open end 14d of the housing 14 extends in the gravitational direction G from the inside of the housing 14 toward the outside of the housing 14. The slope determined by the shape between the position P1 and the position P2 extends from the inside to the outside in the thickness direction of the case 14 and toward the opening direction of the case 14.

As shown in fig. 4, the edge 14e is located outside the lower end of the outer surface 14b, and an edge 14f is formed inside the lower end of the outer surface 14 b. An end face 21 is formed between the edge portions 14e and 14 f. The end surface 21 is a surface inclined with respect to the gravitational direction G. In the side cross-sectional shape of the outer surface 14b, the lower end outer edge 14e is located below the lower end inner edge 14f in the gravity direction G. Here, the side cross section of the outer side surface 14b is a cross section along the thickness direction D and the gravitational direction G of the outer side surface 14 b. Thus, the end face 21 is formed with a slope so that the liquid moves away from the connector portion 15 as it goes toward the gravitational direction G.

When the liquid adheres to the outer surface 14b, the liquid is collected to the outer edge 14e while descending by gravity due to the shape of the end surface 21.

As shown in fig. 2, an end surface 22 inclined with respect to the gravity direction G is also formed on the outer side surface 14 c. The end surface 22 is formed at the lower end of the outer side surface 14 c. The end surface 22 is formed between the lower end outer edge 14g of the outer surface 14c and the lower end inner edge 14j of the outer surface 14 c.

In the side cross-sectional shape of the outer surface 14c, the lower end outer edge 14G is located closer to the gravitational direction G than the lower end inner edge 14 j. The side cross section of the outer side surface 14c is a cross section along the thickness direction D and the gravitational direction G of the outer side surface 14 c. The end face 22 is beveled to allow liquid to exit the connector portion 15 as it moves in the direction of gravity G.

In the case 14, an end face 21 is connected to an end face 22, and a thickened portion 20 is formed at an opening end portion 14 d. Thus, the thickened portion 20 has a slope from the inside toward the outside in the thickness direction of the housing 14 and toward the opening direction of the opening end portion 14 d.

Due to the shape of the thickened portion 20, the liquid adhering to the housing 14 is concentrated on the opening end portion 14d and the rim portion 14 e. The liquid collected in the edge portion 14e is collected in the edge portion 14g along the edge portion 14 e. The end surfaces 21 and 22 may be curved surfaces that are separated from the connector portion 15 as they face the direction of gravity G.

When the end surfaces 21 and 22 are formed in a curved surface, the liquid adhering to the case 14 is also hard to move to the inside of the case 14.

When the switch device 11 attached to the instrument panel 61 encounters water, the liquid attached to the outer side surface 14b moves along the outer side surface 14b in the direction indicated by the arrow a4 by gravity. When the liquid reaches the edge portion 14e, the liquid moves downward by gravity.

The edge 14g of the outer surface 14c is connected to the edge 14e, and the liquid reaching the edge 14e accumulates in the edge 14g and falls downward by gravity.

As shown in fig. 4, when the liquid enters between the opening/closing member 13 and the housing 14, the liquid is concentrated on the outside of the housing 14 by the shape of the thickened portion 20.

The lower end of the opening/closing member 13 is formed horizontally, and the housing 14 extends downward from the opening/closing member 13. The liquid that has entered between the opening and closing member 13 and the housing 14 moves downward along the housing 14 by gravity. The liquid moves in the direction indicated by the arrow a5 due to the shape of the thickened portion 20, and is concentrated on the outside of the housing 14. The liquid collected outside the casing 14 is accumulated along the edge 14e in the edge 14 g.

In this way, the edge portion 14e of the outer surface 14b is recessed upward in side view, whereby the liquid adhering to the outer surface 14b can be collected in the width direction. Since the path of the liquid adhering to the switching device 11 is concentrated on a part of the housing 14, the liquid adhering to the switching device 11 can be easily handled. For example, by disposing the wire 30 so as to avoid the lower side of the edge portion 14g, the influence of the droplets on the wire 30 can be reduced. Further, since the path for discharging the liquid only needs to be provided below the edge portion 14g, the number of drainage members for draining water can be reduced.

The edge portion 14e is formed across the connector portion 15 in a side view. The edge portion 14e is formed in a direction away from the connector portion 15 along the gravitational direction G. Therefore, the liquid moves in the direction away from the connector portion 15 along the edge portion 14e, and the influence of the liquid on the connector portion 15 can be reduced.

In the above-described switchgear 11, the shape of the lower end of the outer side surface 14c may be the same as the shape of the lower end of the outer side surface 14 b. In this case, the liquid adhering to the casing 14 is concentrated at the 2 nd height position P2 of the outer side surface 14 b. The liquid adhering to the housing 14 is concentrated at 4 of the housing 14, and the liquid adhering to the housing 14 is easily handled.

Next, a modified example of the switching device will be described.

Fig. 5 is a diagram showing a switching device 11a according to modification 1. The same portions as those in fig. 3 are denoted by the same reference numerals, and the description thereof will be omitted.

As compared with fig. 3, the shape of the outer surface 14b of the switch device 11a on which the rim 14e is provided is different. The housing 14 includes an outer surface 41 and an outer surface 14 c.

The edge 14g of the outer surface 14c is continuous with the edge 41a of the outer surface 41, and forms an opening end 14d surrounding the connector 15.

In the edge portion 41a, a shape between the position (1 st height position) P3 and the position (2 nd height position) P4 is a curved surface shape inclined with respect to the gravitational direction G. The edge 41a is formed to descend from the position P3 toward the position P4. Therefore, the lower end surface of the edge portion 41a is formed as a curved surface inclined with respect to the gravity direction G. The liquid adhering to the outer surface 41 is collected along the edge 41a to the position P4 while moving in the gravity direction G. A curved surface determined by the shape between the position P3 and the position P4 extends from the inside to the outside in the thickness direction of the case 14 and in the opening direction of the case 14.

By making the edge 41a of the outer surface 41 concave upward in a side view, the liquid adhering to the outer surface 14b can be collected in the width direction.

By concentrating the path of the liquid adhering to the switch device 11 to a part of the housing 14, the liquid adhering to the switch device 11a can be easily dealt with. By providing a portion that concentrates the liquid adhering to the housing 14 so as to surround the opening end portion 14d of the connector portion 15 in this way, the path of the liquid can be easily predicted when the switch device 11a encounters water, and measures against the liquid adhering to the switch device 11a can be easily taken.

Fig. 6 is a diagram showing a switching device 11b according to modification 2.

The shape of the outer surface 14b of the switch device 11b of modification 2 on which the rim portion 14e is provided is different. The housing 14 is composed of an outer surface 42 and an outer surface 14 c.

A rim 42a is provided at the lower end of the outer surface 42. The edge 42a is formed in a V-shape having a lower central portion and a higher side portion in the width direction. That is, the lower end portion of the outer side surface 42 is formed so that the center portion in the width direction protrudes downward.

In the switch device 11b, the opening end portion 14d surrounding the connector portion 15 is formed by the edge portion 14g of the outer surface 14c and the edge portion 42a of the outer surface 42.

In the edge portion 42a, the lowest position (height 2) of the widthwise central portion is a position P5. The position highest at the end in the width direction (the 1 st height position) is a position P6, and is located at both ends in the width direction of the edge portion 41 a. Position P5 is below position P6. The edge portion 42a is connected to the edge portion 14g of the outer side surface 14c at a position P6.

In the edge portion 42a, a shape between the position P5 and the position P6 is formed in a straight line shape inclined with respect to the gravitational direction G. The edge 42a is formed to continuously descend from the position P6 toward the position P5. The liquid adhering to the outer surface 42 moves in the gravity direction G and is collected at the position P5 along the edge 42 a. The curved surface between the position P5 and the position P6 extends from the inside to the outside in the thickness direction of the case 14 and in the opening direction of the case 14.

By providing a portion for concentrating the liquid attached to the housing 14 by surrounding the opening end portion 14d of the connector portion 15, the path of the liquid when the switch device 11b encounters water can be easily predicted, and measures against the liquid attached to the switch device 11b can be easily taken.

The lower end of the outer surface 42 may be inclined outward of the housing 14 in the thickness direction as it goes toward the gravity direction G. The liquid that has entered the inside of the outer surface 42 moves in the thickness direction of the outer surface 42 in a direction away from the connector portion 15. The connector portion 15 and the terminals 31 are protected from the liquid.

Fig. 7 is a diagram showing a switching device 11c according to modification 3.

The switch device 11c of modification 3 has different shapes of the outer surface 14b provided with the edge portion 14 e. The housing 14 is composed of an outer surface 43 and an outer surface 14 c. An edge 43a is provided at the lower end of the outer surface 43. The edge 43a is provided over the entire width of the outer surface 43. The edge 43a is formed in an arc shape having a lower central portion and a higher side portion in the width direction. The lower end of the outer surface 43 is formed so that the center in the width direction protrudes downward.

In the switch device 11c, the opening end portion 14d surrounding the connector portion 15 is formed by the edge portion 14g of the outer surface 14c and the edge portion 43a of the outer surface 43.

In the edge portion 43a, the lowest position (height 2) of the widthwise central portion is a position P7. And, in the edge portion 43a, the position (1 st height position) highest at the end in the width direction is the position P8, located at both ends in the width direction of the edge portion 43 a.

Position P7 is below position P8. The edge 43a is connected to the edge 14g of the outer surface 14c at a position P8.

In the edge portion 43a, a shape between the position P7 and the position P8 is formed into a curved surface shape that always descends toward the position P7 with respect to the gravitational direction G. The edge 43a is formed to continuously descend from the position P7 toward the position P8. The lower end surface of the edge portion 43a is formed as a curved surface inclined with respect to the gravity direction G. The liquid adhering to the outer surface 43 moves in the gravity direction G and is collected at the position P7 along the edge 43 a.

The curved surface formed between the position P7 and the position P8 extends from the inside to the outside in the thickness direction of the case 14 and in the opening direction of the case 14.

By making the edge portion 43a of the outer side surface 43 convex downward in side view, the liquid adhering to the outer side surface 43 can be concentrated at the position P7 at the widthwise center of the outer side surface 43. By concentrating the path of the liquid adhering to the switch device 11c to a part of the housing 14, it is possible to facilitate measures against the liquid adhering to the switch device 11 c.

By providing a portion for concentrating the liquid attached to the housing 14 by surrounding the opening end portion 14d of the connector portion 15, the path of the liquid when the switch device 11c encounters water can be easily predicted, and measures against the liquid attached to the switch device 11c can be easily taken.

Similarly to the switchgear 11 described above, the thickened portion 20 may be formed at the opening end 14d of the housing 14. The lower end of the outer surface 43 may be inclined toward the outer surface of the housing 14 in the thickness direction as it goes toward the gravity direction G. The lower end surface of the edge portion 43a is formed as a curved surface extending outward with respect to the gravity direction G. The liquid that has entered the inside of the outer surface 43 moves in the thickness direction of the outer surface 43 in a direction away from the connector portion 15. And the connector portion 15 and the terminals 31 are protected from the liquid.

In the present embodiment, the opening end portion 14d of the outer peripheral portion 14a of the case 14 of the switchgear 11 has the end surface 21 formed as an inclined slope or the edge portion 41a formed as an inclined curved surface, and therefore the liquid adhering to the outer peripheral portion 14a of the switchgear 11 flows along the end surface 21 or the edge portion 41 a. Therefore, the path of the liquid flow can be restricted, and the path of the liquid can be determined to be in a fixed range. This allows the cable 30 connected to the switch device 11 to be disposed at a position not affected by the liquid.

Further, since the switching device 11 has the end surface 21 or the curved surface from the 1 st height position P1 to the 2 nd height position P2 lower than the first height position P1, the liquid adhering to the switching device 11 moves along the edge portion 14e and flows along the end surface 21 or the edge portion 41 a. Therefore, between the 1 st height position P1 and the 2 nd height position P2, the liquid flows along the edge 41a without falling from the switch device 11. This restricts the path of the liquid, and the path of the liquid flow can be determined to be within a fixed range.

The above embodiments are merely one embodiment of the present invention, and specific embodiments of the present invention and the application range of the present invention are not limited to the above embodiments. In the above embodiment, the edge portion 14e, the edge portion 41a, the edge portion 42a, and the edge portion 43a are provided on the outer side surfaces of the case 14 facing each other. However, the edge portion 14e, the edge portion 41a, the edge portion 42a, or the edge portion 43a may be provided on 1 to 4 outer side surfaces of the case 14. The housing 14 may be formed by combining outer surfaces on which the edge portions 14e, 41a, 42a, and 43a are provided.
