Description

  The present invention relates to an electrical component, and more particularly, to an electrical component suitable for being used outdoors or installed outdoors.

  In recent years, electronic devices have been used outdoors or installed outdoors, and the environmental resistance of electronic devices, particularly water resistance against water, has been demanded. For example, water resistance to water has been demanded for electrical components that are partly exposed outside the vehicle (outdoors), such as electrical components that detect the opening and closing of automobile doors and trunks. For this reason, electrical components having a waterproof structure have become increasingly important.

  As a conventional example of an electrical component having such a waterproof structure, Patent Document 1 proposes a waterproof push switch 900 for a vehicle that is attached to the body of a door portion or a trunk lit portion of the vehicle. FIG. 27 is a longitudinal sectional view showing a conventional waterproof push switch 900 for a vehicle.

  A vehicle waterproof push switch 900 shown in FIG. 27 is fixed to a switch 901 having a pressing body 912 to be pressed on one side, a cover plate 911 formed integrally with a case 901C of the switch 901, and the cover plate 911. A negative electrode plate 902, a waterproof cap 904 that is detachably attached to the flange plate 911 and covers the upper part of the switch 901, and a screw 903 that is inserted into a hole 924h provided in the negative electrode plate 902, the flange plate 911, and the waterproof cap 904. And is composed of. The waterproof push switch 900 for a vehicle has a plus electrode plate 913 connected to another electronic device on the other side of the case 901C. When the automobile door is closed, the pressing body 912 is pressed and the screw 903 is pressed. The negative electrode plate 902 grounded to the body 950 via the positive electrode plate 913 led out to the outside from the case 901C is separated to be in an off state. On the other hand, the pressing force is released by opening the door of the automobile, and the minus electrode plate 902 and the plus electrode plate 913 come into contact with each other to be turned on.

  Further, when the waterproof push switch 900 for a vehicle is inserted into a hole of the body 950 such as a pillar and attached to the body 950, the concave portion 904r of the waterproof cap 904 is engaged with the convex portion 911b on the periphery of the flange plate 911. Therefore, the pinched portion (904n shown in FIG. 27) of the waterproof cap 904 between the convex portion 911b of the flange plate 911 and the body 950 is pressed and deformed by the screwed pressing force. Thereby, the waterproof effect of the switch 901 can be obtained.

As a result, the contact structure between the cover member and the attached portion can be made more reliable, and the waterproof function can be further enhanced.

  Moreover, the electrical component of the present invention is characterized in that an outer peripheral portion of the base portion has an umbrella portion that is formed to extend downward and to become thinner in the extending direction. Yes.

  According to this, when the electrical component is attached to the attachment portion, the attachment portion pushes the umbrella portion upward and outward and press-contacts the attachment portion. For this reason, the contact | adherence structure of a cover member and a to-be-attached part can be made still more reliable. In addition, since the tip side of the umbrella portion is thin, when the cover member is attached to the attached portion, the air between the base portion and the attached portion can be easily released, and the cover member and the attached portion The contact structure can be made even more reliable. As a result, the waterproof function can be further enhanced.

  In the electrical component of the present invention, an engagement member having an engagement protrusion that can be engaged with the attached portion is provided on the inside of the flange portion in a plan view. It is a feature.

For this reason, while being able to fix a case to a to-be-attached part reliably by an engaging protrusion, a case can be hold | maintained without inclining with respect to a to-be-attached part. Thereby, although it is a simple structure, electrical components can be mounted reliably and easily, the close contact structure between the cover member and the attached portion can be ensured, and the waterproof function can be enhanced.

  In the electrical component of the present invention, the cover member is made of an opaque material.

  According to this, it cannot be understood from the user side that the grip portion of the engaging member protrudes inside the cover member. For this reason, for example, it is difficult to understand the removal method except for a person who knows the existence of the engaging member such as a repairer, and the possibility of the user inadvertently removing it can be reduced.

  The electrical component of the present invention includes a movable contact member in which the detection means is housed in the case and can be operated integrally with the operation member, and a fixed contact that is housed in the case and is in contact with the movable contact member. And a member.

  According to this, the movable contact member and the fixed contact member function as a switch that contacts and separates as the operation member is operated. Moreover, since the detection means is housed in the case, waterproofing can be reliably performed. Accordingly, it is possible to provide an electrical component having a waterproof function and a switch function with a simple configuration.

  In the electrical component of the present invention, the fixed contact member includes a first fixed contact portion and a second fixed contact portion that are electrically insulated from each other, and the first fixed contact portion is connected to an external device. The second fixed contact portion is electrically connected to a terminal member made of a metal plate, and the side end surface of the terminal member can be in contact with the attached portion and the case. It has the exposed part exposed from the side part, and the said exposed part is located inside the said cover member, It is characterized by the above-mentioned.

  According to this, it can be made to conduct | electrically_connect from a taking-out terminal to a to-be-attached part via a 1st fixed contact part, a movable contact member, a 2nd fixed contact part, and a terminal member. For this reason, in an electrical component, the number of external terminals (extraction terminals) can be reduced to one.

  Also, the electrical component of the present invention has a first fixed contact portion and a second fixed contact portion in which the fixed contact member is electrically insulated from each other, and the first fixed contact portion is for connection with an external device. The second fixed contact portion is electrically connected to a second extraction terminal for connection to the external device, and the first extraction terminal and the second extraction terminal are electrically connected to the first extraction terminal. It is characterized by being exposed from the other side of the case.

  According to this, both the first extraction terminal and the second extraction terminal are placed in a waterproof environment. Therefore, the first extraction terminal and the second extraction terminal are less likely to rust compared to the conventional example in which one terminal (the negative electrode plate 902) is exposed to a severe environment. As a result, it is possible to provide an electrical component having a switch function capable of reducing the occurrence of poor conduction as much as possible and having a waterproof structure.

  Since the electrical component of the present invention does not require an undercut portion as in the conventional example to be provided on the cover member, the mold structure for producing the cover member can be simplified. Further, since it is not necessary to forcibly pull out the cover member from the mold, it is difficult for scraping to occur, and it is possible to prevent the occurrence of defects due to scraping. Accordingly, an electrical component having a waterproof structure can be provided with a simple configuration.

Is extended upward from the bottom surface located below the recess. Thereby, compared with the case where it extends outward from either of the outer wall parts 51w and it bends in L shape, the engaging member 71 can be arrange | positioned more inside and reduction in size can be achieved. .

  In addition, as shown in FIG. 6, the engaging members 71 are respectively provided (two) at positions facing each other across the accommodating portion K1s, and are provided inside the flange portion 11v in plan view. Yes. Thereby, including the mechanism (engagement member 71) for attaching the electrical component 100 to the attachment portion 500, the attachment hole 500h of the attachment portion 500 can be reliably covered by the cover member C6 attached to the flange portion 11v. it can.

  Further, as shown in FIGS. 6 and 9, the engaging member 71 is provided with a space inside the engaging member 71. Therefore, the accommodating portion K1s is set with the end portion 51e (upper end) of the outer wall portion 51w as a fulcrum. It can swing to the side.

  Further, as shown in FIG. 6, the engaging member 71 can come into contact with the edge portion of the mounting hole 500h (see FIG. 4A) in a side view (see FIG. 8A). In this way, it has an engaging protrusion 71k protruding to the side, and this engaging protrusion 71k is provided on the lower side (Z2 direction side shown in FIG. 6) from the upper case portion 11, and is attached It is arranged on the other side of the part 500.

  As a result, the engaging members 71 having the engaging protrusions 71k are respectively provided at positions facing each other with the accommodating portion K1s interposed therebetween, so that the engaging members 71 come into pressure contact with the attached portion 500 evenly. . For this reason, the case K1 can be reliably fixed to the attached portion 500 by the engaging protrusion 71k, and the case K1 can be held without being inclined with respect to the attached portion 500. Accordingly, the electrical component 100 can be reliably and easily mounted with a simple configuration, and the close contact structure between the cover member C6 and the attached portion 500 is ensured, and the waterproof function is enhanced. Can do.

  Further, as shown in FIG. 9, the engaging protrusion 71k of the engaging member 71 includes an abutment surface 71t provided to face the attached portion 500, and an outer wall of the lower case portion 51 as it goes upward from below. The guide surface 71g is formed so as to be gradually separated from the portion 51w.

  Thus, when the case K1 is inserted into the attached portion 500, the guide surface 71g smoothly slides along the edge of the attachment hole 500h of the attached portion 500, and the engaging member 71 is moved in the swinging direction. Oscillates in the direction. When the engaging protrusion 71k is inserted into the mounting hole 500h, the engaging member 71 swings outward in the swing direction, and the contact surface 71t faces the mounted portion 500. It becomes like this. Thus, when the electrical component 100 is attached to the attached portion 500, the engaging member 71 is attached as shown in FIGS. 5 (b), 6, 8 (a), and 9. The electrical component 100 is fixed to the mounted portion 500 by engaging with the mounting portion 500. That is, so-called snap-in engagement is easily performed.

  In addition, the respective engaging protrusions 71k provided on the two engaging members 71 are disposed on the same circumference and at positions that equally divide the circumference in plan view. That is, in the first embodiment of the present invention, since the two engagement protrusions 71k are provided, the two engagement protrusions 71k are provided at positions where the circumference is divided in half (opposite positions).

  Thereby, as above-mentioned, the two engaging protrusions 71k come to press-contact with the to-be-attached part 500 equally. Therefore, the case K1 can be securely fixed to the attached portion 500, and the case K1 can be held without being inclined with respect to the attached portion 500. In the first embodiment of the present invention, the two engaging members 71 are provided at the opposing positions. However, the present invention is not limited to this, and a configuration in which three or four members are provided may be used. In that case, it is preferable that the plurality of engaging members 71 are arranged in a well-balanced position on the same circumference and equally dividing the circumference in plan view (in top view). That is, it goes without saying that, for example, when there are three engaging protrusions 71k, they are arranged at positions that are divided by 120 °, and when there are four engaging protrusions 71k, they are arranged at positions that are divided by 90 °. The As described above, it is possible to easily mount the electrical component 100 with a simple configuration.

  Next, the operation member S3 and the detection means M5 of the electrical component 100 will be described.

  First, the operation member S3 of the electric component 100 will be described. FIG. 11A is a perspective view showing the operation member S3 and the detection means M5, and FIG. 11B is a front view of FIG. 11A viewed from the Y2 side. 12A is a perspective view in which the fixed contact member 5B in FIG. 11A is omitted, and FIG. 12B is a front view in which the operation member S3 in FIG. 11B is omitted.

  The operation member S3 of the electrical component 100 is manufactured by injection molding using a synthetic resin such as ABS resin (ABS, acrylonitrile butadiene styrene copolymer) or polyacetal resin (POM, polyoxymethylene), and has a rectangular parallelepiped shape as shown in FIG. The box-shaped base portion 13 that has an external appearance and is opened on the lower side, and the columnar operation portion 53 that extends upward from the upper surface of the base portion 13 are configured. When the electrical component 100 is assembled, as shown in FIGS. 6 and 7, the upper side of the base portion 13 of the operation member S3 and the operation portion 53 are arranged so as to protrude upward from the opening K1h of the case K1. And is housed inside the cover member C6.

  Further, since the upper end portion of the operation portion 53 is disposed in contact with the inner side of the cover member C6 (specifically, the inner side of a pusher portion 56p provided on the top of the lid portion 56 described later), the cover member When a pressing operation is performed on C6, the operation member S3 moves downward. Also, as shown in FIGS. 6 and 7, one side of the biasing member F4 (specifically, the coil spring in the first embodiment of the present invention) is housed inside the base portion 13, The operation member S3 is urged to one side (the top side of the cover member C6) by the urging member F4. Thereby, after the operation member S3 is moved downward against the repulsive force of the urging member F4, when the pressing operation is released with respect to the cover member C6, the operation member S3 is moved upward. become.

  The operation member S3 can be smoothly moved up and down in the vertical direction on the side wall of the base portion 13 of the operation member S3 (see FIG. 11) and the housing portion K1s of the case K1. This is because the projection K1t (see FIGS. 1 and 7) provided on the inner wall is engaged with the projection. Further, a claw portion 13m (see FIG. 11) projecting sideways is formed on the side wall of the base portion 13 of the operation member S3. Although not shown in detail, the claw portion 13m is formed in the case K1. Is engaged with the receiving portion of the inner wall of the inner wall to restrict the excessive upward movement of the operation member S3.

  Next, the detection means M5 of the electrical component 100 will be described. As shown in FIG. 1, the detection means M5 includes a movable contact member 5A that can operate integrally with the operation member S3, and two fixed contact members 5B that can contact the movable contact member 5A. Yes. Further, the movable contact member 5A and the fixed contact member 5B use metal plates, and are manufactured by cutting or bending. In the first embodiment of the present invention, the two fixed contact members 5B are composed of a first fixed contact portion B15 and a second fixed contact portion B25 that are electrically insulated from each other. The movable contact member 5A and the two fixed contact members 5B (the first fixed contact portion B15 and the second fixed contact portion B25) of the detection means M5 are accommodated in the case K1.

  When the electrical component 100 is assembled, as shown in FIG. 12A, the movable contact member 5A is fixed to the side wall of the base portion 13 of the operation member S3, and as shown in FIG. Each of the two sliders of the movable contact member 5A is disposed at a position where it contacts the first fixed contact portion B15 and the second fixed contact portion B25 (in FIG. 12B, the second fixed contact portion. Only B25 is shown). As a result, the first fixed contact portion B15 and the second fixed contact portion B25 are electrically connected via the movable contact member 5A, that is, a so-called closed state.

  When a pressing operation is performed downward on the operation member S3 via the cover member C6, the slider of the movable contact member 5A is separated from the first fixed contact portion B15 and the second fixed contact portion B25. To come. As a result, the first fixed contact portion B15 and the second fixed contact portion B25 are electrically disconnected, so-called open state.

  In this way, in the first embodiment of the present invention, the movable contact members 5A and 2 are used by using the movable contact member 5A and the two fixed contact members 5B (the first fixed contact portion B15 and the second fixed contact portion B25). The detecting means M5 is configured by bringing the two fixed contact members 5B into and out of contact with each other. The detection means M5 detects the operation of the operation member S3 when the operation member S3 is operated, and functions as a switch device that can switch between the open state and the closed state. Moreover, since the detection means M5 is housed in the case K1, the cover member C6 can reliably waterproof the detection means M5.

  Next, the cover member C6 of the electrical component 100 will be described. FIG. 13A is an upper perspective view of the cover member C6, and FIG. 13B is a lower perspective view of the cover member C6. FIG. 14A is a front view of the cover member C6, and FIG. 14B is a longitudinal sectional view of the cover member C6. 13 and 14 show the cover member C6 in a state where it is not attached to the case K1.

  The cover member C6 of the electrical component 100 is formed by transfer molding synthetic rubber, which is a waterproof and elastic material, and has a hole 16k as shown in FIGS. The base portion 16 formed on the base portion 16, the cylindrical portion 36 extending from the inner edge of the base portion 16 facing the hole portion 16 k and elastically deformable, and the side of the cylindrical portion 36 facing the hole portion 16 k are closed. The lid portion 56 includes an outer peripheral wall portion 76 that protrudes upward from the outer edge of the base portion 16 and has a cylindrical shape. In the state where the cover member C6 is not attached to the case K1, the cylindrical portion 36 is formed in a cylindrical shape.

  As shown in FIGS. 6 and 7, the cover member C <b> 6 extends from the hole 16 k (see FIGS. 13B and 14B) to the space inside the cylindrical portion 36 and opens the case K <b> 1. The K1h side is inserted to cover the opening K1h side of the case K1 (upper case portion 11). In that case, the outer shape of the flange portion 11v of the upper case portion 11 is larger than the inner shape of the cylindrical portion 36 of the cover member C6 before the cover member C6 is attached to the case K1 (upper case portion 11). Therefore, the cylindrical portion 36 is elastically deformed along the circular outer shape of the flange portion 11v and is attached to the case K1. That is, when the electrical component 100 is attached to the attached portion 500, a part of the cylindrical portion 36 and a part of the base portion 16 are sandwiched between the attached portion 500 and the flange portion 11v. The so-called undercut portion is clearly formed in the cover member C6.

  Thereby, it is not necessary to previously provide an undercut shape portion as in the conventional example in the cover member C6, and the cover member C6 can be used as a waterproof member. As a result, the mold structure for producing the cover member C6 can be simplified, and when the cover member C6 is formed, it is not necessary to pull out the cover member C6 when the cover member C6 is removed from the mold. Therefore, it is difficult for scraps to be generated, and it is possible to prevent occurrence of defects due to scraps.

  Further, when the electrical component 100 is attached to the attached portion 500, the cover member C6 covers the attachment hole 500h as shown in FIGS. 6 and 7, and as shown in FIGS. A part of the cylindrical part 36 deformed along the outer shape of the part 11v and a part of the base part 16 are pressed and clamped by the flange part 11v and the attached part 500. For this reason, the opening K1h side of the case K1 can be waterproofed by the cover member C6 covering the attachment hole 500h of the attached portion 500 into which the other side of the case K1 is inserted.

  Next, each component of the cover member C6 will be described in detail.

  First, as shown in FIGS. 13B and 14B, the base portion 16 of the cover member C6 is formed in a ring shape having a cylindrical hole portion 16k, and the electric component 100 is attached. When attached to the part 500, as shown in FIG. 6 and FIG. The hole portion 16k referred to here indicates a space of a portion located inside the base portion 16 having a ring shape.

  Further, on the side (lower side) where the cylindrical portion 36 of the base portion 16 is not provided (as shown in FIG. 13B), it is provided annularly along the entire circumference of the hole portion 16k, and is downward from the lower surface of the base portion 16. It has a projecting portion 16t projecting from the top. Thus, when the electrical component 100 is attached to the attached portion 500, the projecting portion 16t is preferentially urged and brought into pressure contact with the attached portion 500.

  Furthermore, at least a part of the protruding portion 16t overlaps with the flange portion 11v in plan view (see FIGS. 9 and 10). For this reason, as shown in FIGS. 9 and 10, when the electric component 100 is attached to the attached portion 500 and the flange portion 11v is pressed downward, the base portion 16 is moved downward via the tubular portion 36. The projecting portion 16t is urged by the attached portion 500 to be surely pressed. As a result, the contact structure between the cover member C6 and the attached portion 500 can be made more reliable, and the waterproof function can be further enhanced. In the first embodiment of the present invention, the projecting portion 16t is configured to overlap with the flange portion 11v over the entire circumference in plan view, so that the close contact structure between the cover member C6 and the attached portion 500 is provided. Is more certain.

  Further, as shown in FIG. 14 (b), the outer peripheral portion of the outer lower end of the base portion 16 extends downward and outwards in the longitudinal direction as viewed in the longitudinal direction (lower outward direction). An umbrella portion 16a formed so as to be thin is provided over the entire circumference. As a result, when the electrical component 100 is attached to the attached portion 500, the umbrella portion 16a is pushed upward and outward (side) by the upper surface of the attached portion 500, and the attached portion 500. (Refer to FIG. 14B and FIG. 10). For this reason, the contact | adherence structure of the cover member C6 and the to-be-attached part 500 can be made still more reliable. Moreover, since the tip side of the umbrella portion 16a is thin, when the cover member C6 is attached to the attached portion 500, air between the base portion 16 and the attached portion 500 can be easily released, and the cover The contact structure between the member C6 and the attached portion 500 can be further ensured. As a result, the waterproof function can be further enhanced.

  Next, as shown in FIG. 14B, the cylindrical portion 36 of the cover member C6 is formed to extend from the upper surface of the inner edge portion of the base portion 16 facing the hole portion 16k. It is formed so that it can be sufficiently elastically deformed. Although not shown in detail, in the state where the cover member C6 is not attached to the case K1, the outer shape (outer diameter) of the cylindrical portion 36 is viewed in plan from the lid portion 56 side, and the case K1 ( It is configured to be smaller than the outer shape (outer diameter) of the flange portion 11v of the upper case portion 11). For this reason, as shown in FIGS. 6 and 7, when the case K1 (upper case portion 11) is inserted over the hole 16k of the cover member C6 and the space inside the cylindrical portion 36, the cylindrical portion 36 is inserted. Is stretched (elastically deformed) and attached along the outer shape of the flange portion 11v.

  Further, when the cover member C6 is attached to the case K1 (upper case portion 11), as shown in FIGS. 6, 7, 9, and 10, a part of the cylindrical portion 36 is the flange portion 11v. It comes to be located between an outer peripheral part and the outer peripheral wall part 76. FIG. Thus, the outer peripheral wall portion 76 protects the cylindrical portion 36 located on the outer peripheral portion side (the extending direction side of the flange portion 11v) of the flange portion 11v from external factors such as physical impact. it can.

  Next, as shown in FIGS. 13 and 14, the cover portion 56 of the cover member C <b> 6 is formed so as to close the side facing the hole 16 k in the tubular portion 36, and continues from the tubular portion 36. The dome-shaped dome portion 56d formed and a columnar pusher portion 56p provided on the top of the dome portion 56d are mainly configured.

  Further, as shown in FIGS. 9 and 10, the lower side portion 56 t on the tubular portion 36 side of the dome portion 56 d of the lid portion 56 is formed so as to protrude downward from a position connected to the lid portion 56. Has been. When the cover member C6 is attached to the case K1 (upper case portion 11), the position where the lower side portion 56t faces the step portion 11d of the flange portion 11v of the upper case portion 11, that is, the first restricting portion 11z. The position of the lower side portion 56t facing the step portion 11d is used as the second restricting portion 56z. For this reason, when the cover member C6 is attached to the case K1, the first restricting portion 11z and the second restricting portion 56z are engaged.

  Thereby, when the cylindrical part 36 elastically deforms along the external shape of the collar part 11v and covers the collar part 11v, it prevents that the cover part 56 is pulled and deform | transformed to the extension direction side of the collar part 11v. be able to. That is, since only the tubular portion 36 is pulled more, the tubular portion 36 is extended and attached so as to be more closely attached to the flange portion 11v. As a result, a gap generated between the tubular portion 36 and the flange portion 11v can be reduced, and the tubular portion 36 can be more closely attached to the flange portion 11v. Furthermore, when the cover member C6 is attached to the case K1 or when the operation member S3 is operated, the lid portion 56 can be prevented from undesirably spreading and deforming.

  Further, as shown in FIG. 14B, a concave hollow portion 56r is provided on the inner surface of the pusher portion 56p of the lid portion 56 on the cylindrical portion 36 side, and the electric component 100 is assembled. As shown in FIGS. 6 and 7, the operation portion 53 of the operation member S3 is accommodated in the recess portion 56r. Thereby, when pressing operation and operation cancellation are performed with respect to the cover member C6, operation | movement to the up-down direction of operation member S3 can be performed stably.

  Finally, as shown in FIGS. 13A and 14B, the outer peripheral wall portion 76 of the cover member C6 is located above the upper surface of the outer edge of the base portion 16 (Z1 direction shown in FIGS. 13 and 14). ) And projecting toward the outer periphery of the cylindrical portion 36 so as to surround the cylindrical portion 36. Further, as shown in FIG. 14B, the outer peripheral wall portion 76 is configured to be thicker than the cylindrical portion 36. Thereby, protection from the external factor in the cylindrical part 36 located in the outer side of the collar part 11v mentioned above can be performed reliably. Accordingly, for example, the tubular portion 36 can be prevented from being broken and the durability of the cover member C6 can be improved.

  Further, when the electric component 100 is attached to the attached portion 500, the protruding end 76e in the protruding direction (upward) of the outer peripheral wall 76 is viewed in a longitudinal section as shown in FIGS. It is located above the upper surface of the flange portion 11v. Thereby, the cylindrical part 36 located in the upper surface side (projection direction side of the outer peripheral wall part 76) of the collar part 11v can be protected from an external factor.

  Further, as shown in FIGS. 6 and 7, the protruding end 76 e in the protruding direction of the outer peripheral wall portion 76 is positioned above the case K <b> 1 (upper case portion 11) in the longitudinal section. As a result, even if the operation stroke becomes longer than usual due to some external factor, the outer peripheral wall 76 serves as a stopper, and excessive shock is applied to the inside of the case K1 via the operation member S3. Can be protected from being added. Thereby, the durability of the electrical component 100 can be further improved.

  Finally, the connector housing H8 and the extraction terminal TA9 of the electrical component 100 according to the first embodiment of the present invention will be described.

  First, the connector housing H8 of the electrical component 100 is injection-molded simultaneously with the case K1, and is formed into a box shape and formed integrally with the case K1, as shown in FIGS. The connector housing H8 is formed in a size that can be inserted into the mounting hole 500h of the mounted portion 500.

  Further, an extraction terminal TA9 for electrical connection with an external device is embedded and fixed in the connector housing H8. As shown in FIG. 3B, a part of the extraction terminal TA9 is part of the connector housing. It is exposed to the space inside the connector housing H8 toward the opening side of the H8.

  Next, as shown in FIG. 1, the takeout terminal TA9 of the electrical component 100 includes a first takeout terminal 19 that is electrically connected to the first fixed contact B15 of the detection means M5, and a second fixed contact B25 of the detection means M5. The mating connector (not shown) is inserted into the connector housing H8, and is electrically connected to an external device. The first attachment terminal 19 is formed integrally with the first fixed contact portion B15. Similarly, the second attachment terminal 29 is formed integrally with the second fixed contact portion B25.

  Since the first extraction terminal 19 and the second extraction terminal 29 are disposed so as to be exposed from the other side of the case K1 (lower case portion 51), the electric component 100 is attached to the attachment portion 500. When this is done, it comes to be located on the opposite side of the cover member C6 with the attached portion 500 interposed therebetween. Thereby, both the first extraction terminal 19 and the second extraction terminal 29 are placed in a waterproof environment, and compared with the conventional example in which one terminal (negative electrode plate 902) is exposed to a severe environment, The 1st extraction terminal 19 and the 2nd extraction terminal 29 become difficult to rust. This can reduce the occurrence of poor conduction as much as possible.

  Further, the extraction terminal TA9 is manufactured integrally with the fixed contact member 5B, and is insert-molded when the case K1 and the connector housing H8 are injection-molded. The lead terminal TA9 is silver-plated on the surface for the stability of electrical connection. The attachment terminal TA9 and the fixed contact member 5B may be attached to the case K1 having the connector housing H8 by press fitting.

  The effects of the electrical component 100 according to the first embodiment of the present invention configured as described above will be collectively described below.

  The electric component 100 according to the present invention includes a base portion 16 in which a cover member C6 has a hole portion 16k and is formed in a plate shape, and a cylindrical portion 36 that extends from an inner edge portion of the hole portion 16k and is elastically deformable. The lid portion 56 closes the side of the tubular portion 36 that faces the hole 16k, and the tubular portion 36 of the cover member C6 is elastically deformed and attached along the outer shape of the flange portion 11v. The configuration. For this reason, it is not necessary to previously provide the undercut-shaped part like the conventional example in the cover member C6. As a result, the mold structure for producing the cover member C6 can be simplified, and it is not necessary to forcibly remove the cover member C6 from the mold. It is difficult to prevent the occurrence of defects due to scraps. Therefore, it is possible to provide the electrical component 100 having a waterproof structure with a simple configuration.

  Further, a part of the cylindrical part 36 and a part of the base part 16 which are deformed along the outer shape of the flange part 11v are pressed and clamped by the flange part 11v and the attached part 500, so that the other side of the case K1 is inserted. The opening K1h side of the case K1 can be waterproofed by the cover member C6 that covers the mounting hole 500h of the mounted portion 500 that has been mounted. For this reason, although it is a simple structure which does not provide an undercut shape part in the cover member C6 like a prior art example, waterproofing can be performed reliably.

  Further, when the cover member C6 is attached to the case K1, the first restriction portion 11z provided in the flange portion 11v of the case K1 and the second restriction portion 56z provided in the lid portion 56 of the cover member C6 are engaged. Therefore, when the cylindrical portion 36 is elastically deformed along the outer shape of the flange portion 11v and covers the flange portion 11v, the lid portion 56 is prevented from being deformed by being pulled toward the extending direction side of the flange portion 11v. be able to. For this reason, the clearance gap produced between the cylindrical part 36 and the collar part 11v can be made small, and the cylindrical part 36 can be closely_contact | adhered to the collar part 11v more. By this, a waterproof function can be improved more. Further, since the deformation of the lid portion 56 is prevented, the operability when the operation member S3 is operated via the cover member C6 is not adversely affected.

  Moreover, since a part of the cylindrical part 36 is located between the outer peripheral wall part 76 thicker than the cylindrical part 36 and the flange part 11v of the case K1, the outer peripheral part side of the flange part 11v (the extension of the flange part 11v) It is possible to protect the cylindrical portion 36 located on the outgoing side) from external factors such as physical impact. Accordingly, for example, the tubular portion 36 can be prevented from being broken and the durability of the cover member C6 can be improved.

  Further, since the protruding end 76e in the protruding direction of the outer peripheral wall portion 76 is positioned above the upper surface of the flange portion 11v in a vertical cross-sectional view, on the upper surface side (the protruding direction side of the outer peripheral wall portion 76) of the flange portion 11v. The positioned cylindrical portion 36 can be protected from external factors. As a result, for example, the tubular portion 36 can be prevented from being broken, and the durability of the cover member C6 can be further improved.

  Further, since the protruding end 76e in the protruding direction of the outer peripheral wall portion 76 is located above the case K1 in a longitudinal section, the operation stroke may be longer than usual due to some external factor. Even if it does, the outer peripheral wall part 76 will play the role of a stopper, and it can protect so that an excessive impact may not be added to the inside of the case K1 via the operation member S3. Thereby, the durability of the electrical component 100 can be further improved.

  Further, since at least a part of the annular projecting portion 16t provided on the side where the cylindrical portion 36 of the base portion 16 is not provided (on the attached portion 500 side) overlaps with the flange portion 11v in plan view, When the electrical component 100 is attached to the attached portion 500, the projecting portion 16t is preferentially urged and brought into pressure contact with the attached portion 500. As a result, the contact structure between the cover member C6 and the attached portion 500 can be made more reliable, and the waterproof function can be further enhanced.

  In addition, since the outer peripheral portion of the base portion 16 includes the umbrella portion 16a that extends downward and outward and becomes thinner in the extending direction, the electric component 100 is attached to the attached portion 500. When attached, the umbrella portion 16a is pushed upward and outward by the attached portion 500 and is pressed against the attached portion 500. For this reason, the contact | adherence structure of the cover member C6 and the to-be-attached part 500 can be made still more reliable. Moreover, since the tip end side of the umbrella portion 16a is thin, when the cover member C6 is attached to the attached portion 500, the air between the base portion 16 and the attached portion 500 can be easily released, and the cover member C6. And the attached portion 500 can be made more reliable. As a result, the waterproof function can be further enhanced.

  Further, since the engaging member 71 having the engaging protrusion 71k that can be engaged with the attached portion 500 is disposed inside the flange portion 11v, a mechanism (engaging member) for attaching the electric component 100 to the attached portion 500. 71) and the cover member C6 attached to the flange portion 11v can reliably cover the attachment hole 500h of the attached portion 500. Thereby, the waterproof performance of the electrical component 100 can be further improved.

  In addition, since the detection means M5 has the movable contact member 5A that can operate integrally with the operation member S3 and the fixed contact member 5B that can contact the movable contact member 5A, the operation member S3 is operated. The movable contact member 5A and the fixed contact member 5B function as a switch for contacting and separating. In addition, since the detection means M5 is accommodated in the case K1, waterproofing can be reliably performed. Accordingly, it is possible to provide the electrical component 100 having a waterproof function and a switch function with a simple configuration.

  Further, the first extraction terminal 19 integrally connected to the first fixed contact portion B15 and the second extraction terminal 29 integrally connected to the second fixed contact portion B25 are exposed from the other side of the case K1. Thus, when the electric component 100 is attached to the attached portion 500, the electric component 100 is positioned on the opposite side of the cover member C6 with the attached portion 500 interposed therebetween. For this reason, both the first extraction terminal 19 and the second extraction terminal 29 are placed in a waterproof environment, and compared with the conventional example in which one terminal (the negative electrode plate 902) is exposed to a severe environment, The 1st extraction terminal 19 and the 2nd extraction terminal 29 become difficult to rust. As a result, it is possible to provide the electrical component 100 having a switch function that can reduce the occurrence of poor conduction as much as possible and having a waterproof structure.

In addition, the lower case portion 51 is inserted into the attachment hole 500h and disposed on the other side (the Z2 direction side shown in FIG. 23) of the attached portion 500. In the second embodiment of the present invention, at the same time as the case K21, the connector housing H8 that holds the extraction terminal TA29 is also integrally formed by injection molding.

  Further, as shown in FIGS. 18 and 21, the case K21 is formed with an accommodation portion K1s formed by the upper case portion 11 and the lower case portion 51 so as to be continuous with the opening K1h, as shown in FIG. As described above, the operation member S3 is accommodated in the accommodation portion K1s. The case K21 supports the operation member S3 so that the operation member S3 can move in the vertical direction (Z direction shown in FIGS. 18 and 19).

  Further, as shown in FIG. 17, a U-shaped groove K1u formed across the upper case portion 11 and the lower case portion 51 is formed on the side surface portion of the case K21. ), The concave groove K1u is provided at two positions at opposite positions. This position is substantially orthogonal to a position where an engagement member 271 described later is provided in plan view (top view). That is, the two concave grooves K1u and the two engaging members 271 are disposed at positions shifted by approximately 90 °.

  Next, each component of case K21 is demonstrated.

  First, as shown in FIG. 23A, the upper case portion 11 of the case K21 has a protruding portion that protrudes to the side (the X direction shown in FIG. 23A) from the lower case portion 51 in a side view. 11t and a flange portion 11v protruding further to the side than the protruding portion 11t. In other words, as shown in FIG. 22B, the protruding portion 11t is formed so as to protrude outward from the lower case portion 51 in a plan view (viewed from the bottom) from the lower case portion 51 side. As shown in FIG. 22 (a), it is formed so as to protrude outward from the outer edge of the upper case portion 11 (case K21) in plan view (upper surface see-through) from the opening K1h side. . Both the projecting portion 11t and the flange portion 11v are formed so as to have an outer shape larger than the mounting hole 500h and are not inserted into the mounting hole 500h of the mounted portion 500.

  Further, as shown in FIG. 21 and FIG. 22A, the upper case portion 11 is provided with two peripheral housing portions 11s disposed at a position surrounding the housing portion K1s as viewed from above. ing. As shown in FIG. 22A, the two peripheral housing portions 11s pass through a part of the projecting portion 11t, and an engagement member 271 is disposed respectively.

  As shown in FIG. 23, the protruding portion 11t of the upper case portion 11 is opposed to or in contact with the surface on one side of the mounted portion 500 at the edge of the mounting hole 500h of the mounted portion 500. As shown in FIG. 2, the cover member C6 (specifically, a base portion 16 described later) is in contact with the cover member C6. In the second embodiment of the present invention, the protruding portion 11t is provided only on both sides in one direction (the X direction shown in FIG. 23 (a)) as shown in FIGS. 22 (b) and 23. Although not provided in the orthogonal direction (Y direction shown in FIG. 23B) orthogonal to one direction, the present invention is not limited to this. For example, it may be provided so as to protrude in all directions, or may be provided over the entire circumference.

  Further, as shown in FIG. 24, a stepped portion 11d extending upward (in the Z1 direction shown in FIG. 24) is formed on the upper surface of the flange portion 11v of the upper case portion 11, and this stepped portion is formed. A position facing the cover member C6 in 11d (specifically, the second restricting portion 56z in the dome portion 56d of the lid portion 56) is used as the first restricting portion 11z. The first restricting portion 11z is formed on the inner peripheral side of the upper surface of the flange portion 11v. As shown in FIGS. 20 and 21, the step portion 11d is formed over the entire circumference of the flange portion 11v. However, the present invention is not limited to this. For example, even if a part of the step portion 11d is notched. good.

  Next, as shown in FIG. 23, the lower case portion 51 of the case K21 has a rectangular shape having four faces, and has a box shape having an accommodating portion K1s configured with the upper case portion 11. Yes. Moreover, since the outer wall part 51w which forms the outer periphery of the lower case part 51 is comprised smaller than the opening shape of the attachment hole 500h of the to-be-attached part 500, the lower case part 51 can be inserted in the attachment hole 500h. When the electric component 200 is attached to the attached portion 500, it is disposed on the other side of the attached portion 500 (see FIGS. 18 and 23).

  Finally, the engagement member 271 of the case K21 can be engaged with the edge portion of the attachment hole 500h (see FIG. 24) of the attached portion 500 as shown in FIG. In this way, it has an engaging protrusion 71k protruding to the side and a gripping portion 271j provided at the upper end portion extending to the upper side of the upper case portion 11.

  As shown in FIG. 21, two engaging members 271 are arranged at positions facing each other with the accommodating portion K1s interposed therebetween. As shown in FIG. 11v inside. Thereby, including the mechanism (engagement member 271) for attaching the electrical component 200 to the attachment portion 500, the attachment hole 500h of the attachment portion 500 is surely covered by the cover member C6 attached to the flange portion 11v. it can. Thereby, the waterproof performance of the electric component 200 can be further improved. Moreover, compared with a mechanism for screwing at one position away from the hole of the body 950, such as the conventional waterproof push switch 900 for a vehicle, the electrical component 200 of the second embodiment of the present invention is Since it is engaged at the edge portion of the mounting hole 500h of the mounting portion 500, it is surely locked to the mounted portion 500. Thereby, the waterproof performance of the electrical component 200 can be further enhanced.

  Further, as shown in FIGS. 16 (b) and 23 (b), the engaging member 271 is provided with a lower end portion connected to an outer wall portion 51 w that forms the outer periphery of the lower case portion 51, and this outer wall portion. As shown in FIGS. 20 and 21, it extends upward from the end 51e (upper end) of the 51w concave portion (stepped portion) and passes through the peripheral housing portion 11s (see FIG. 20). Projecting in the Z1 direction). Particularly in the second embodiment, as in the first embodiment, the engaging member 271 is located on the upper case portion 11 side of the outer wall portion 51w of the lower case portion 51, as shown in FIG. The engaging member 271 extends from the bottom surface (end 51e) located below the recess. Thereby, compared with the case where it extends outward from either of the outer wall parts 51w and it bends in L shape, the engaging member 271 can be arrange | positioned more inside, and size reduction can be achieved. .

  Further, as shown in FIG. 18, the engaging member 271 is formed in a state where a space is provided at a position inside the engaging member 271, and is located at the end 51e of the outer wall 51w (below the recess). With the portion) as a fulcrum, it can swing toward the housing portion K1s while being elastically deformed. That is, it can be said that the engaging member 271 is formed of an elastic piece having a lower end portion connected to the lower case portion 51.

  Next, the engagement protrusion 71k and the grip 271j of the engagement member 271 will be described in more detail.

  First, as shown in FIG. 23, the engaging protrusion 71k of the engaging member 271 is provided on the lower side (Z2 direction side shown in FIG. 23) from the upper case portion 11, and is arranged on the other side of the attached portion 500. It is set up. As described above, the engaging protrusions 71k are provided at positions facing each other with the accommodating portion K1s interposed therebetween.

  Thereby, the engaging member 271 comes to press-contact the to-be-attached part 500 equally by the engaging protrusion 71k. For this reason, the case K21 can be reliably fixed to the attached portion 500 by the engaging protrusion 71k, and the case K21 can be held without being inclined with respect to the attached portion 500. Accordingly, the electric component 200 can be reliably and easily mounted with a simple configuration, and the close contact structure between the cover member C6 and the attached portion 500 is ensured, and the waterproof function is enhanced. Can do.

  In addition, the respective engaging protrusions 71k provided on the two engaging members 271 are disposed on the same circumference and at positions that equally divide the circumference in plan view. That is, in the second embodiment of the present invention, since the two engagement protrusions 71k are the same as in the first embodiment, the two engagement protrusions 71k are arranged at positions where the circumference is divided in half (opposite positions). It was set as the structure provided.

  Thereby, as above-mentioned, the two engaging protrusions 71k come to press-contact with the to-be-attached part 500 equally. For this reason, the case K21 can be securely fixed to the attached portion 500, and the case K21 can be held without being inclined with respect to the attached portion 500. In the second embodiment of the present invention, the two engaging members 271 are provided at opposing positions. However, the present invention is not limited to this, and a configuration in which three or four members are provided may be used. In that case, it is preferable that the plurality of engaging members 271 are arranged in a balanced manner at positions on the same circumference and equally dividing the circumference in plan view (in top view). As described above, the electric component 200 can be easily mounted with a simple configuration.

  Further, as shown in FIG. 24, the engaging protrusion 71k includes an abutting surface 71t provided to face the plate-like attached portion 500, and an outer wall portion 51w of the lower case portion 51 from the lower side to the upper side. The guide surface 71g is formed so as to be gradually separated from the guide surface.

  As a result, when the case K21 is inserted into the mounted portion 500, the guide surface 71g smoothly slides along the edge of the mounting hole 500h of the mounted portion 500, and the engaging member 271 moves in the swinging direction. Oscillates in the direction. When the engaging protrusion 71k is completely inserted into the mounting hole 500h, the engaging member 271 swings outward in the swinging direction, and the contact surface 71t faces the mounted portion 500. It becomes like this. Thus, when the electrical component 200 is attached to the attached portion 500, the engaging member 271 engages with the attached portion 500 as shown in FIGS. 18, 23 (a), and 24. Thus, the electric component 200 is fixed to the attached portion 500. That is, so-called snap-in engagement is easily performed.

  Next, as shown in FIG. 23, the grip portion 271j of the engagement member 271 protrudes upward from the upper case portion 11, so that it can be gripped from the outside of the cover member C6 having elasticity. When the grip portion 271j is gripped, the engagement member 271 tilts (swings) toward the accommodation portion K1s with the end portion 51e (upper end) of the lower case portion 51 as a fulcrum. Thus, the engaging member 271 (gripping part 271j) can be operated via the cover member C6.

  Thus, when the electric component 200 is attached to the attached portion 500, the engaging protrusion 71k is moved from the outside of the cover member C6 toward the accommodating portion K1s while the engaging protrusion 71k is attached to the attachment hole 500h of the attached portion 500. After that, the engaging protrusion 71k and the attached portion 500 can be easily engaged with each other by returning the swing of the grip portion 271j to the initial state. On the other hand, after the electric component 200 is attached to the attached portion 500, the engaging protrusion 71k and the attached portion are moved by swinging the grip portion 271j toward the accommodating portion K1s from the outside of the cover member C6 through the cover member C6. The engagement with 500 can be easily removed, and the electric component 200 can be easily removed from the attached portion 500. For these reasons, the electric component 200 can be easily detached while having a simple configuration. In particular, in the second embodiment, a set of engaging members 271 are provided at positions opposed to each other with the accommodating portion K1s interposed therebetween, so that the gripping portions 271j of both engaging members 271 can be grasped at the same time, and more detachable Good workability.

  Next, the cover member C6 of the electric component 200 will be described. The cover member C6 has the same configuration as that of the first embodiment, like the operation member S3, the urging member F4, and the connector housing H8. Explain.

  The cover member C6 of the electric component 200 is formed by transfer molding synthetic rubber, which is a waterproof and elastic material, and includes a base portion 16 formed in a plate shape with a hole portion 16k, and a hole. A cylindrical portion 36 that extends from the edge of the base portion 16 facing the portion 16k and is elastically deformable, a lid portion 56 that covers the side of the cylindrical portion 36 that faces the hole 16k, and an upper side from the outer edge of the base portion 16 And an outer peripheral wall 76 that is formed in a cylindrical shape.

  The cover member C6 has an opening K1h side of the case K21 inserted from the hole 16k (see FIGS. 13 (b) and 14 (b)) to the space inside the cylindrical portion 36, and the case K21 (upper It covers the opening K1h side of the case portion 11). In that case, before the cover member C6 is attached to the case K21 (upper case portion 11), the outer shape of the flange portion 11v of the upper case portion 11 is larger than the inner shape of the cylindrical portion 36 of the cover member C6. Therefore, the cylindrical portion 36 is elastically deformed along the outer shape of the flange portion 11v and is attached to the case K21. That is, when the electric component 200 is attached to the attached portion 500, a part of the tubular portion 36 and a part of the base portion 16 are sandwiched between the attached portion 500 and the flange portion 11v. The so-called undercut portion is clearly formed in the cover member C6.

  Thereby, it is not necessary to previously provide an undercut shape portion as in the conventional example in the cover member C6, and the cover member C6 can be easily used as a waterproof member. As a result, the mold structure for producing the cover member C6 can be simplified, and when the cover member C6 is formed, it is not necessary to pull out the cover member C6 when the cover member C6 is removed from the mold. Therefore, it is difficult for scraps to be generated, and it is possible to prevent occurrence of defects due to scraps.

  Further, when the electrical component 200 is attached to the attached portion 500, the cover member C6 covers the attachment hole 500h as shown in FIGS. 18 and 19, and as shown in FIG. A part of the cylindrical part 36 and a part of the base part 16 which are deformed along the outer shape are pressed and clamped by the flange part 11v and the attached part 500. For this reason, the opening K1h side of the case K21 can be waterproofed by the cover member C6 that covers the mounting hole 500h of the mounted portion 500 into which the other side of the case K21 is inserted.

  The cover member C6 is made of a synthetic rubber material made of an opaque material. From the user side, it cannot be seen that the grip portion 271j of the engagement member 271 protrudes inside the cover member C6. For this reason, for example, it is difficult for a person other than a person who knows the existence of the engaging member 271 like a repairer to understand how to remove it, and the possibility that the user may inadvertently remove it can be reduced.

  Next, each component of the cover member C6 will be described in detail.

  First, the base portion 16 of the cover member C6 is formed in a ring shape having a cylindrical hole portion 16k, and when the electric component 200 is attached to the attached portion 500, FIG. 18 and FIG. As shown, it comes into contact with the surface on one side of the mounted portion 500.

  Next, the cylindrical portion 36 of the cover member C6 is formed to extend from the upper surface of the inner edge portion of the base portion 16 facing the hole portion 16k, and is thinner than the base portion 16 and sufficiently elastically deformed. It is formed to be able to.

  Although not shown in detail, when the cover member C6 is not attached to the case K21, the outer shape (outer diameter) of the cylindrical portion 36 is viewed from the lid portion 56 side in a plan view, and the case K21 ( It is configured to be smaller than the outer shape (outer diameter) of the flange portion 11v of the upper case portion 11). For this reason, as shown in FIGS. 18 and 19, when the case K21 (upper case portion 11) is inserted over the hole 16k of the cover member C6 and the space inside the cylindrical portion 36, the cylindrical portion 36 is inserted. Is stretched (elastically deformed) and attached along the outer shape of the flange portion 11v.

  Further, when the cover member C6 is attached to the case K21 (upper case portion 11), as shown in FIGS. 18, 19, and 24, a part of the cylindrical portion 36 is connected to the outer peripheral portion of the flange portion 11v. It comes to be located between the outer peripheral wall portions 76. Thus, the outer peripheral wall portion 76 protects the cylindrical portion 36 located on the outer peripheral portion side (the extending direction side of the flange portion 11v) of the flange portion 11v from external factors such as physical impact. it can.

  Next, the lid portion 56 of the cover member C6 is formed so as to close the side of the cylindrical portion 36 that faces the hole 16k, and a dome-shaped dome portion 56d that is formed continuously from the cylindrical portion 36; The cylindrical pusher portion 56p provided at the top of the dome portion 56d is mainly configured.

  Further, as shown in FIG. 24, the lower side portion 56 t on the cylindrical portion 36 side in the dome portion 56 d of the lid portion 56 is formed so as to protrude downward from a position connected to the lid portion 56. . When the cover member C6 is attached to the case K21 (upper case portion 11), the position where the lower side portion 56t faces the step portion 11d of the flange portion 11v of the upper case portion 11, that is, the first restricting portion 11z. The position of the lower side portion 56t facing the step portion 11d is used as the second restricting portion 56z. For this reason, when attaching the cover member C6 to the case K21, the first restricting portion 11z and the second restricting portion 56z are engaged.

  Thereby, when the cylindrical part 36 elastically deforms along the external shape of the collar part 11v and covers the collar part 11v, it prevents that the cover part 56 is pulled and deform | transformed to the extension direction side of the collar part 11v. be able to. That is, since only the tubular portion 36 is pulled more, the tubular portion 36 is extended and attached so as to be more closely attached to the flange portion 11v. As a result, a gap generated between the tubular portion 36 and the flange portion 11v can be reduced, and the tubular portion 36 can be more closely attached to the flange portion 11v. Furthermore, when the cover member C6 is attached to the case K21 or when the operation member S3 is operated, the lid portion 56 can be prevented from undesirably spreading and deforming.

  Finally, as shown in FIGS. 13A and 14B, the outer peripheral wall portion 76 of the cover member C6 is located above the upper surface of the outer edge of the base portion 16 (Z1 direction shown in FIGS. 13 and 14). ) And projecting toward the outer periphery of the cylindrical portion 36 so as to surround the cylindrical portion 36. Further, as shown in FIG. 14B, the outer peripheral wall portion 76 is configured to be thicker than the cylindrical portion 36. Thereby, protection from the external factor in the cylindrical part 36 located in the outer side of the collar part 11v mentioned above can be performed reliably. Accordingly, for example, the tubular portion 36 can be prevented from being broken and the durability of the cover member C6 can be improved.

  Finally, the detection means M25, the terminal member T7, and the extraction terminal TA29 of the electrical component 200 will be described.

  FIG. 25 is a view for explaining the detecting means M25, the terminal member T7, and the takeout terminal TA29 according to the second embodiment of the present invention. FIG. 25 (a) is a view from the intermediate side between X1 and Y2 shown in FIG. FIG. 25B is an upper perspective view seen from the side opposite to FIG. 25A. FIG. 26 is an enlarged view of a portion S shown in FIG.

  First, as shown in FIG. 25, the detection means M25 of the electrical component 200 includes a movable contact member 5A that can operate integrally with the operation member S3, and two fixed contact members 5C that can contact the movable contact member 5A. It is configured. In addition, the movable contact member 5A and the fixed contact member 5C use metal plates and are manufactured by cutting or bending. In the second embodiment of the present invention, the two fixed contact members 5C are configured by a first fixed contact portion C15 and a second fixed contact portion C25 that are electrically insulated from each other. Further, the movable contact member 5A and the two fixed contact members 5C (the first fixed contact portion C15 and the second fixed contact portion C25) of the detection means M25 are accommodated in the case K21.

  When the electric component 200 is assembled, the movable contact member 5A is fixed to the side wall of the base portion 13 of the operation member S3. As shown in FIG. 25B, the two sliding contacts of the movable contact member 5A are performed. Each of the children (four sliders in total) is disposed at a position where it contacts the first fixed contact portion C15 and the second fixed contact portion C25. As a result, the first fixed contact portion C15 and the second fixed contact portion C25 are electrically connected via the movable contact member 5A, that is, a so-called closed state.

  When the pressing operation is performed downward on the operation member S3 via the cover member C6, the slider of the movable contact member 5A is separated from the first fixed contact portion C15 and the second fixed contact portion C25. Will come to do. As a result, the first fixed contact portion C15 and the second fixed contact portion C25 are electrically disconnected, so-called open state. At this time, the slider of the movable contact member 5A may be separated from at least one of the two fixed contact members 5C (for example, the first fixed contact portion C15), and the other (for example, the second fixed contact portion C25). ) May be in contact.

  As described above, in the second embodiment of the present invention, the movable contact members 5A and 2 are used by using the movable contact member 5A and the two fixed contact members 5C (the first fixed contact portion C15 and the second fixed contact portion C25). The detecting means M25 is configured by bringing the fixed contact members 5C into and out of contact with each other. The detection means M25 detects the operation of the operation member S3 when the operation member S3 is operated, and functions as a switch device that can switch between the open state and the closed state. And since this detection means M25 is accommodated in case K21, waterproofing can be reliably performed by the cover member C6.

  Next, the terminal member T7 of the electric component 200 includes a flat plate-like substrate part T7d formed in a semi-ring shape, and side end parts T7e extending substantially vertically from the both end sides of the semi-ring shape. , Is composed of. The terminal member T7 is made of a metal plate, like the movable contact member 5A and the fixed contact member 5C, and is manufactured by cutting or bending.

  The board portion T7d of the terminal member T7 is embedded and disposed in the upper case portion 11, and as shown in FIG. 21, the upper surface portion is exposed to the outside on the opening K1h side of the case K21. This exposed part is located on the inner side (accommodating part K1s side) than the step part 11d of the flange part 11v.

  Moreover, as shown to Fig.25 (a), the board | substrate part T7d is connected with the 2nd fixed contact part C25 by welding, caulking, etc., and is conducted. Although it is difficult to understand in FIG. 25, the substrate portion T7d (terminal member T7) and the first fixed contact portion C15 are separated from each other and are electrically insulated from each other.

  The side end portion T7e of the terminal member T7 has a U-shaped cross section as shown in FIG. 25. As shown in FIGS. 21, 22A and 23A, the case K21 is formed. Are respectively accommodated in U-shaped concave grooves K1u formed in the side surface portion. At that time, the concave end portion side of the side end portion T7e is exposed to the outside of the case K21.

  And when the electrical component 200 is attached to the to-be-attached part 500, as shown in FIG. 26, it is comprised so that the concave edge of the side edge part T7e may contact | abut to the to-be-attached part 500. In addition, the part which can contact | abut this to-be-attached part 500 is made into the exposed part T7r in the terminal member T7. That is, the exposed portion T7r is provided on each of the side portions of the case K21 facing each other with the accommodating portion K1s interposed therebetween.

  Thereby, when the electrical component 200 is attached to the attached portion 500, the second fixed contact portion C25 is electrically connected to the attached portion 500 via the terminal member T7. In addition, since the side end portion T7e is formed in a U-shape, it comes into contact with the attached portion 500 at two places (four places when both sides are combined), and the stability of the connection is further improved.

  The exposed portion T7r is located on a different surface from the outer wall portion 51w provided with the engaging member 271. Specifically, in the second embodiment of the present invention, the position of the concave groove K1u (exposed portion T7r) provided in the lower case portion 51 and the engaging member 271 are provided in plan view (top view). It is arranged substantially perpendicular to the position where it is placed. That is, the two exposed portions T7r and the two engaging members 271 are disposed at positions shifted by approximately 90 °.

  Accordingly, the exposed portion T7r and the engaging member 271 can be easily disposed in the case K21 without causing interference, and a plurality of exposed portions T7r can be provided. As a result, the terminal member T7 and the attached portion 500 can be connected by the plurality of exposed portions T7r and the attached portion 500, so that the reliability of the conductive connection can be improved. Further, even if the cover member C6 is made of an opaque material, the grip portion 271j of the engagement member 271 can be gripped using the exposed portion T7r as a mark, and the work is performed when the operator performs the detachment work. It becomes easy.

  Finally, as shown in FIG. 25, the takeout terminal TA29 of the electrical component 200 is formed integrally with the first fixed contact C15 of the detection means M25, and FIGS. 18, 22 (b) and 23 (b). As shown in FIG. Then, a mating connector (not shown) is inserted into the connector housing H8, and electrical connection with an external device is performed. The extraction terminal TA29 is insert-molded when the case K21 and the connector housing H8 are injection-molded together with the fixed contact member 5C and the terminal member T7. Further, the surface of the lead terminal TA29 is silver-plated for the stability of electrical connection. The fixed contact member 5C and the terminal member T7 may be attached to the case K21 having the connector housing H8 by press fitting.

  With the above configuration, the electrical component 200 can have one external terminal (extraction terminal TA29), and the extraction terminal TA29 can be connected to the first fixed contact portion C15, the movable contact member 5A, and the second fixed contact. It is possible to conduct to the attached portion 500 (being a ground) through the portion C25 and the terminal member T7.

  When the electrical component 200 is attached to the attached portion 500, the extraction terminal TA29 comes to be located on the opposite side of the cover member C6 with the attached portion 500 interposed therebetween, and the side portion of the case K21. The exposed portion T7r exposed from the inside is positioned inside the cover member C6. As a result, the extraction terminal TA29 and the exposed portion T7r (the mounting hole 500h of the mounted portion 500) are placed in a waterproof environment, and one terminal (the negative electrode plate 902) is exposed to a severe environment. As compared with, the extraction terminal TA29 and the exposed portion T7r are less likely to rust. This can reduce the occurrence of poor conduction as much as possible.

  The effects of the electrical component 200 according to the second embodiment of the present invention configured as described above will be collectively described below.

  In the electrical component 200 according to the second embodiment of the present invention, the cover member C6 has a hole 16k and is formed in a plate shape, and is extended from the inner edge of the hole 16k and is elastically deformable. It has a cylindrical portion 36 and a lid portion 56 that closes the side of the cylindrical portion 36 that faces the hole 16k, and the cylindrical portion 36 of the cover member C6 is elastically deformed along the outer shape of the flange portion 11v. It was set as the structure which was attached. For this reason, it is not necessary to previously provide the undercut-shaped part like the conventional example in the cover member C6. As a result, the mold structure for producing the cover member C6 can be simplified, and it is not necessary to forcibly remove the cover member C6 from the mold. It is difficult to prevent the occurrence of defects due to scraps. Therefore, it is possible to provide the electric component 200 having a waterproof structure with a simple configuration.

  Further, a part of the cylindrical part 36 and a part of the base part 16 which are deformed along the outer shape of the flange part 11v are pressed and clamped by the flange part 11v and the attached part 500, so that the other side of the case K21 is inserted. The opening K1h side of the case K21 can be waterproofed by the cover member C6 that covers the mounting hole 500h of the mounted portion 500 that has been mounted. For this reason, although it is a simple structure which does not provide an undercut shape part in the cover member C6 like a prior art example, waterproofing can be performed reliably.

  Further, when the cover member C6 is attached to the case K21, the first restriction portion 11z provided in the flange portion 11v of the case K21 and the second restriction portion 56z provided in the lid portion 56 of the cover member C6 are engaged. Therefore, when the cylindrical portion 36 is elastically deformed along the outer shape of the flange portion 11v and covers the flange portion 11v, the lid portion 56 is prevented from being deformed by being pulled toward the extending direction side of the flange portion 11v. be able to. For this reason, the clearance gap produced between the cylindrical part 36 and the collar part 11v can be made small, and the cylindrical part 36 can be closely_contact | adhered to the collar part 11v more. By this, a waterproof function can be improved more. Further, since the deformation of the lid portion 56 is prevented, the operability when the operation member S3 is operated via the cover member C6 is not adversely affected.

  Moreover, since a part of the cylindrical part 36 is located between the outer peripheral wall part 76 thicker than the cylindrical part 36 and the collar part 11v of the case K21, the outer peripheral part side (the extension of the collar part 11v) of the collar part 11v. It is possible to protect the cylindrical portion 36 located on the outgoing side) from external factors such as physical impact. Accordingly, for example, the tubular portion 36 can be prevented from being broken and the durability of the cover member C6 can be improved.

  Further, since the engaging member 271 having the engaging protrusion 71k that can be engaged with the attached portion 500 is disposed inside the flange portion 11v, a mechanism (engaging member) for attaching the electric component 200 to the attached portion 500. 271) and the attachment hole 500h of the attached portion 500 can be reliably covered by the cover member C6 attached to the flange portion 11v. Thereby, the waterproof performance of the electric component 200 can be further improved.

  Further, the engaging member 271 connected to the outer wall portion 51w of the lower case portion 51 of the case K21 so as to be elastically deformable has a grip portion 271j extending above the upper case portion 11 as viewed from the side. Therefore, even after the cover member C6 is attached to the case K21, the grip portion 271j can be operated via the cover member C6. For this reason, when the electric component 200 is attached to the attached portion 500, the engaging protrusion 71k is moved from the outside of the cover member C6 toward the accommodating portion K1s while the engaging protrusion 71k is attached to the attachment hole 500h of the attached portion 500. After that, the engaging protrusion 71k and the attached portion 500 can be easily engaged with each other by returning the swing of the grip portion 271j to the initial state. On the other hand, after the electric component 200 is attached to the attached portion 500, the engaging protrusion 71k and the attached portion are moved by swinging the grip portion 271j toward the accommodating portion K1s from the outside of the cover member C6 through the cover member C6. The engagement with 500 can be easily removed, and the electric component 200 can be easily removed from the attached portion 500. For these reasons, the electric component 200 can be easily detached while having a simple configuration.

  Moreover, since the engaging member 271 is extended from the bottom face of the recessed part provided in the outer wall part 51w of the lower case part 51, it extends outward from either of the outer wall parts 51w, and is bent in L shape. Compared with the case, the engaging member 271 can be arranged further inside. For this reason, the engaging member 271 can be easily extended in the upper case portion 11, and the grip portion 271j can be easily accommodated in the cover member C6.

  In addition, since the engaging members 271 are provided at positions facing each other with the accommodating portion K1s interposed therebetween, the engaging members 271 (engaging protrusions 71k) are in pressure contact with the attached portion 500 evenly. For this reason, the case K21 can be reliably fixed to the attached portion 500 by the engaging protrusion 71k, and the case K21 can be held without being inclined with respect to the attached portion 500. Accordingly, the electric component 200 can be reliably and easily mounted with a simple configuration, and the close contact structure between the cover member C6 and the attached portion 500 is ensured, and the waterproof function is enhanced. Can do.

  Further, since the cover member C6 is made of an opaque material, it cannot be seen from the user side that the grip portion 271j of the engagement member 271 protrudes inside the cover member C6. For this reason, for example, it is difficult for a person other than a person who knows the existence of the engaging member 271 like a repairer to understand how to remove it, and the possibility that the user may inadvertently remove it can be reduced.

  In addition, since the detection means M25 has a movable contact member 5A that can operate integrally with the operation member S3 and a fixed contact member 5C that can contact the movable contact member 5A, the operation member S3 is operated. The movable contact member 5A and the fixed contact member 5C function as a switch for contacting and separating. Moreover, since the detection means M25 is accommodated in the case K21, waterproofing can be reliably performed. Accordingly, it is possible to provide the electrical component 200 having a switch function and a waterproof structure with a simple configuration.

  Further, the first fixed contact portion C15 is electrically connected to the take-out terminal TA29 for electrical connection with an external device, and the second fixed contact portion C25 has an exposed portion T7r that can contact the attached portion 500. Since it is electrically connected to the terminal member T7, it is electrically connected from the take-out terminal TA29 to the mounted portion 500 via the first fixed contact portion C15, the movable contact member 5A, the second fixed contact portion C25, and the terminal member T7. be able to. For this reason, the electrical component 200 can have one external terminal (extraction terminal TA29).
