  As shown in FIG. 6, the engagement member 71 can come into contact with the edge of the mounting hole 500h (see FIG. 4A) when viewed from the side (see FIG. 8A). As described above, the engaging projection 71k is provided on the lower side (Z2 direction side shown in FIG. 6) from the upper case 11 and is attached to the mounting projection 71k. It is arranged on the other side of the part 500.

  Accordingly, since the engaging members 71 having the engaging protrusions 71k are provided at positions opposing each other with the housing portion K1s interposed therebetween, the engaging members 71 come into pressure contact with the mounted portion 500 evenly. . Therefore, the case K1 can be securely fixed to the attached portion 500 by the engaging projection 71k, and the case K1 can be held without being inclined with respect to the attached portion 500. This makes it possible to securely and easily mount the electric component 100 while having a simple configuration, to secure the close contact structure between the cover member C6 and the mounted portion 500, and to enhance the waterproof function. Can be.

  As shown in FIG. 9, the engagement protrusion 71 k of the engagement member 71 includes an abutting surface 71 t provided to face the attached portion 500 and an outer wall of the lower case portion 51 as going upward from below. And a guide surface 71g formed so as to be gradually separated from the portion 51w.

  Thus, when the case K1 is inserted into the mounting portion 500, the guide surface 71g smoothly slides along the edge of the mounting hole 500h of the mounting portion 500, and the engaging member 71 moves in the swing direction. It will swing toward the direction. Then, when all of the engaging protrusions 71k are inserted into the mounting holes 500h, the engaging members 71 swing outward in the swing direction, and the contact surface 71t faces the attached portion 500. Become like In this way, when the electric component 100 is attached to the attachment portion 500, as shown in FIGS. 5B, 6, 8A, and 9, the engagement member 71 is attached. The electric component 100 is fixed to the mounted part 500 by engaging with the mounting part 500. That is, so-called snap-in engagement is easily performed.

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

  Thus, as described above, the two engaging protrusions 71k come into pressure contact with the mounted portion 500 evenly. Therefore, the case K1 can be securely fixed to the mounted portion 500, and the case K1 can be held without being inclined with respect to the mounted portion 500. In the first embodiment of the present invention, two engaging members 71 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 this case, it is preferable that the plurality of engaging members 71 be disposed in a well-balanced position on the same circumference and equally dividing the circumference when viewed in a plan view (when viewed from above). In other words, needless to say, for example, when the number of the engaging protrusions 71k is three, the position is divided into 120 °, and when the number of the engaging protrusions 71k is four, the position is divided into 90 °. You. As described above, the electric component 100 can be easily mounted with a simple configuration.

  Next, the operation member S3 and the detection means M5 of the electric 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 unit M5, and FIG. 11B is a front view of FIG. 11A as viewed from the Y2 side. FIG. 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 electric component 100 is manufactured by injection molding using a synthetic resin such as an ABS resin (ABS, acrylonitrile butadiene styrene copolymer) or a polyacetal resin (POM, polyoxymethylene). The base 13 has a box-like base 13 having an open bottom, and a columnar operation unit 53 extending upward from the upper surface of the base 13. Then, when the electric component 100 is assembled, as shown in FIGS. 6 and 7, the upper side of the base 13 of the operation member S3 and the operation section 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 inside of the cover member C6 (specifically, the inside of a presser portion 56p provided on the top of the lid portion 56 described later), the cover member is provided. When the pressing operation is performed on C6, the operation member S3 operates downward. As shown in FIGS. 6 and 7, one side of a biasing member F4 (specifically, a coil spring in the first embodiment of the present invention) is housed inside the base portion 13. The operating member S3 is urged to one side (the top side of the cover member C6) by the urging member F4. Thus, when the pressing operation on the cover member C6 is released after the operation member S3 is operated downward against the repulsive force of the urging member F4, the operation member S3 operates upward. become.

  The operation member S3 can be smoothly moved in the vertical direction because of the concave groove portion 13r (see FIG. 11) formed in the side wall of the base portion 13 of the operation member S3 in the vertical direction, and the housing portion K1s of the case K1. Is engaged with the projection K1t (see FIGS. 1 and 7) provided on the inner wall facing the. On the side wall of the base portion 13 of the operation member S3, a claw portion 13m (see FIG. 11) protruding laterally is formed, and although not shown in detail, the claw portion 13m is formed of the case K1. And restricts excessive upward movement of the operation member S3.

  Next, the detection unit M5 of the electric component 100 will be described. As shown in FIG. 1, the detection means M5 includes a movable contact member 5A operable integrally with the operation member S3, and two fixed contact members 5B capable of contacting the movable contact member 5A. I have. The movable contact member 5A and the fixed contact member 5B are made of a metal plate, and are manufactured by performing a cutting process, a bending process, and the like. In the first embodiment of the present invention, the two fixed contact members 5B include 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 detecting means M5 are housed in the case K1.

  When the electric component 100 is assembled, as shown in FIG. 12A, the movable contact member 5A is fixed to the side wall of the base 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 comes into contact with the first fixed contact portion B15 and the second fixed contact portion B25 (in FIG. 12 (b), the second fixed contact portion). Only B25 is shown). Thus, 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 the operation member S3 is pressed downward via the cover member C6, the slider of the movable contact member 5A separates from the first fixed contact portion B15 and the second fixed contact portion B25. I will do it. Thus, the first fixed contact portion B15 and the second fixed contact portion B25 are electrically disconnected, that is, a so-called open state.

  As described above, in the first embodiment of the present invention, the movable contact members 5A and 5A 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 detection 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 resulting from the operation of the operation member S3, and functions as a switch device that can switch between an open state and a closed state. Moreover, since the detection means M5 is housed in the case K1, the detection means M5 can be reliably waterproofed by the cover member C6.

  Next, the cover member C6 of the electric 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 the cover member C6 is not attached to the case K1.

  The cover member C6 of the electric component 100 is formed by transfer molding synthetic rubber which is a material having waterproofness and elasticity, and has a plate-like shape having a hole 16k as shown in FIGS. , A cylindrical portion 36 extending from the inner edge of the base portion 16 facing the hole 16k and elastically deformable, and closing the side of the cylindrical portion 36 facing the hole 16k. It has a lid portion 56 and a cylindrical outer peripheral wall portion 76 that protrudes upward from the outer edge of the base portion 16 and is formed in a cylindrical shape. In a state where the cover member C6 is not mounted on the case K1, the tubular portion 36 is formed in a cylindrical shape.

  Then, as shown in FIGS. 6 and 7, the cover member C6 extends from the hole 16k (see FIGS. 13B and 14B) to the space inside the cylindrical portion 36 to open the case K1. The K1h side is inserted, and covers the opening K1h side of the case K1 (upper case portion 11). At that time, before the cover member C6 is attached to the case K1 (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 tubular portion 36 of the cover member C6. 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 electric component 100 is mounted on the mounting portion 500, a part of the tubular portion 36 and a part of the base portion 16 are sandwiched between the mounting portion 500 and the flange portion 11v. Thus, a so-called undercut portion is clearly formed on the cover member C6.

  Thus, it is not necessary to provide an undercut portion in the cover member C6 in advance as in the conventional example, and the cover member C6 can be used as a waterproof member. Thereby, the mold structure for producing the cover member C6 can be simplified, and when the cover member C6 is formed, the cover member C6 can be removed from the mold without excessive pulling. Therefore, shavings are less likely to occur, and it is possible to prevent problems caused by shavings.

  When the electric component 100 is mounted on the mounting portion 500, as shown in FIGS. 6 and 7, the cover member C6 covers the mounting hole 500h, and as shown in FIGS. A portion of the cylindrical portion 36 deformed along the outer shape of the portion 11v and a portion of the base portion 16 are pressed and held between the flange portion 11v and the attached portion 500. For this reason, 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 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 16 of the cover member C6 is formed in a ring shape having a cylindrical hole 16k, and the electric component 100 is attached thereto. When attached to the part 500, as shown in FIGS. 6 and 7, it comes into contact with one surface of the attached part 500. The hole 16k referred to here indicates a space of a portion located inside the base 16 having a ring shape.

  On the side (lower side) of the base portion 16 where the cylindrical portion 36 is not provided, as shown in FIG. And a protruding portion 16t protruding from the front end. Thus, when the electric component 100 is mounted on the mounting portion 500, the protruding portion 16t is urged by the mounting portion 500 preferentially and pressed against the mounting portion 500.

  Further, at least a part of the protruding portion 16t overlaps with the flange portion 11v in a plan view (see FIGS. 9 and 10). Therefore, 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 lowered via the cylindrical portion 36. , And the protruding portion 16t is urged by the attached portion 500 to be surely pressed. Thereby, the contact structure between the cover member C6 and the mounted portion 500 can be made more reliable, and the waterproof function can be further enhanced. In the first embodiment of the present invention, since the projecting portion 16t overlaps the entire circumference of the flange portion 11v in a plan view, the close contact structure between the cover member C6 and the mounted portion 500 is provided. Is more certain.

  As shown in FIG. 14 (b), the outer peripheral portion of the outer lower end of the base portion 16 extends downward and outward in the longitudinal direction, and extends in the extending direction (downward outward direction). An umbrella portion 16a having a small thickness is provided over the entire circumference. Thereby, when the electric component 100 is mounted on the mounting portion 500, the umbrella portion 16a is pushed upward and outward (to the side) by the upper surface of the mounting portion 500, and the mounting portion 500 is spread. (See FIGS. 14B and 10). Therefore, the structure of the close contact between the cover member C6 and the mounted portion 500 can be further ensured. Moreover, since the front end side of the umbrella portion 16a is thin, when the cover member C6 is mounted on the mounted portion 500, air between the base portion 16 and the mounted portion 500 can be easily released, and the cover The structure of the close contact between the member C6 and the mounted portion 500 can be further ensured. With these, 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 of the base portion 16 facing the hole portion 16k. It is formed so that it is thinner than that and can be elastically deformed sufficiently. Although not shown in detail, in a state where the cover member C6 is not attached to the case K1, the outer shape (outer diameter) of the tubular portion 36 is viewed from above the lid portion 56 in a plan view, and the case K1 ( The outer case (outer diameter) of the flange 11v of the upper case 11) is configured to be smaller. Therefore, as shown in FIGS. 6 and 7, when the case K1 (upper case portion 11) is inserted into the hole 16k of the cover member C6 and the space inside the cylindrical portion 36, the cylindrical portion 36 Is stretched (elastically deformed), and is mounted along the outer shape of the flange portion 11v.

  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 tubular portion 36 is formed by the flange portion 11v. It is located between the outer peripheral portion and the outer peripheral wall portion 76. Thus, the outer peripheral wall portion 76 protects the cylindrical portion 36 located on the outer peripheral side of the flange portion 11v (extending direction side of the flange portion 11v) from external factors, for example, physical impact. it can.

  Next, as shown in FIGS. 13 and 14, the lid portion 56 of the cover member C6 is formed so as to close the side of the tubular portion 36 facing the hole 16k, and is continuously formed from the tubular portion 36. It is mainly composed of the formed dome-shaped dome portion 56d and a cylindrical presser portion 56p provided on the top of the dome portion 56d.

  As shown in FIGS. 9 and 10, a lower portion 56t of the dome portion 56d of the lid portion 56 on the cylindrical portion 36 side is formed so as to protrude downward from a position connected to the lid portion 56. Have been. When the cover member C6 is mounted on the case K1 (upper case portion 11), the lower portion 56t is opposed to the step portion 11d of the flange portion 11v of the upper case portion 11, that is, the first regulating portion 11z. And a position opposing the step portion 11d in the lower portion 56t is used as a second restricting portion 56z. Therefore, when the cover member C6 is mounted on the case K1, the first restricting portion 11z and the second restricting portion 56z come into engagement.

  Accordingly, when the cylindrical portion 36 elastically deforms along the outer shape of the flange portion 11v to cover the flange portion 11v, the lid portion 56 is prevented from being deformed by being pulled toward the extension direction side of the flange portion 11v. be able to. That is, since only the tubular portion 36 is further pulled, the tubular portion 36 is extended and attached so as to be more closely attached to the flange portion 11v. Thus, the gap generated between the tubular portion 36 and the flange 11v can be reduced, and the tubular portion 36 can be more closely attached to the flange 11v. Further, when the cover member C6 is attached to the case K1 or when the operation member S3 is operated, it is possible to prevent the cover portion 56 from undesirably expanding and deforming.

  Also, as shown in FIG. 14B, a concave recess 56r is provided on the inner surface of the pressing portion 56p of the lid portion 56 on the side of the cylindrical portion 36, and when the electric component 100 is assembled. As shown in FIGS. 6 and 7, the operation section 53 of the operation member S3 is housed in the recess 56r. Thereby, when a pressing operation or an operation release is performed on the cover member C6, the operation of the operation member S3 in the vertical direction can be stably performed.

  Lastly, 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 (in the Z1 direction shown in FIGS. 13 and 14). ), And is formed in a cylindrical shape so as to surround the cylindrical portion 36. Further, the outer peripheral wall portion 76 is configured to be thicker than the cylindrical portion 36, as shown in FIG. Accordingly, protection of the tubular portion 36 located outside the flange portion 11v from an external factor can be reliably performed. Thus, for example, the occurrence of breakage of the tubular portion 36 can be prevented, and the durability of the cover member C6 can be improved.

  Further, when the electric component 100 is mounted on the mounting portion 500, the protruding end 76e of the outer peripheral wall portion 76 in the protruding direction (upward), as shown in FIG. 6 and FIG. It is located above the upper surface of the flange 11v. Thus, the cylindrical portion 36 located on the upper surface side (the protruding direction side of the outer peripheral wall portion 76) of the flange portion 11v can be protected from external factors.

  Further, the protruding end 76e of the outer peripheral wall portion 76 in the protruding direction is located above the case K1 (upper case portion 11) in a longitudinal sectional view as shown in FIGS. As a result, even if the operation stroke becomes longer than usual due to some external factor, the outer peripheral wall portion 76 functions as a stopper, and an excessive impact is applied to the inside of the case K1 via the operation member S3. Can be protected from being added. Thus, the durability of the electric component 100 can be further improved.

  Finally, the connector housing H8 and the extraction terminal TA9 of the electric 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 at the same time as the case K1, and is formed into a box shape 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.

  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 connected to the connector housing H8. It is exposed to the space inside the connector housing H8 toward the opening side of H8.

  Next, as shown in FIG. 1, the extraction terminal TA9 of the electric component 100 includes the first extraction terminal 19 electrically connected to the first fixed contact portion B15 of the detection means M5, and the second fixed contact portion B25 of the detection means M5. And a second extraction terminal 29 that is electrically connected to the external housing. A mating connector (not shown) is inserted into the connector housing H8, and electrical connection with an external device is performed. The first mounting terminal 19 is formed integrally with the first fixed contact portion B15. Similarly, the second mounting 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 arranged so as to be exposed from the other side of the case K1 (the lower case portion 51), the electric component 100 is attached to the attachment portion 500. When the cover member C6 is pressed, the cover member C6 is located on the opposite side of the mounted portion 500. As a result, both the first extraction terminal 19 and the second extraction terminal 29 are placed in a waterproof environment, and compared with a conventional example in which one terminal (the negative electrode plate 902) is exposed to a severe environment. The first extraction terminal 19 and the second extraction terminal 29 are less likely to rust. As a result, occurrence of conduction failure can be reduced 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 surface of the extraction terminal TA9 is plated with silver for 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 electric component 100 according to the first embodiment of the present invention configured as described above will be described below.

  In the electric component 100 of the present invention, the cover member C6 includes the base portion 16 formed in a plate shape having the hole portion 16k, and the cylindrical portion 36 extending from the inner edge of the hole portion 16k and elastically deformable. And a cover portion 56 for closing the side of the tubular portion 36 facing the hole 16k, and the tubular portion 36 of the cover member C6 is attached by being elastically deformed along the outer shape of the flange portion 11v. Configuration. For this reason, it is not necessary to provide an undercut portion in the cover member C6 in advance as in the conventional example. As a result, the mold structure for manufacturing the cover member C6 can be simplified, and unnecessary removal when removing the cover member C6 from the mold does not occur. And it is possible to prevent the occurrence of problems due to shavings. Therefore, it is possible to provide the electric component 100 having the waterproof structure while having a simple configuration.

  Also, a part of the cylindrical portion 36 and a part of the base portion 16 deformed along the outer shape of the flange portion 11v are pressed and held by the flange portion 11v and the attached portion 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. For this reason, it is possible to reliably perform waterproofing with a simple configuration in which an undercut-shaped portion is not provided on the cover member C6 as in the conventional example.

  When the cover member C6 is mounted on the case K1, the first restricting portion 11z provided on the flange portion 11v of the case K1 and the second restricting portion 56z provided on the lid portion 56 of the cover member C6 engage. Therefore, when the cylindrical portion 36 elastically deforms 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 extension direction side of the flange portion 11v. be able to. For this reason, the gap generated between the cylindrical portion 36 and the flange portion 11v can be reduced, and the cylindrical portion 36 can be more closely attached to the flange portion 11v. Thereby, the waterproof function can be further enhanced. In addition, 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.

  In addition, since a part of the cylindrical portion 36 is located between the outer peripheral wall portion 76 having a greater thickness than the cylindrical portion 36 and the flange portion 11v of the case K1, the outer peripheral side of the flange portion 11v (the extension of the flange portion 11v). The tubular portion 36 located on the (outward side) can be protected from external factors, for example, physical impact. Thus, for example, the occurrence of breakage of the tubular portion 36 can be prevented, and the durability of the cover member C6 can be improved.

  In addition, since the protruding end 76e of the outer peripheral wall 76 in the protruding direction is located above the upper surface of the flange 11v in a longitudinal cross-sectional view, the upper end of the flange 11v (in the protruding direction of the outer peripheral wall 76) is located on the upper side. The located cylindrical portion 36 can be protected from external factors. Thereby, for example, the occurrence of breakage or the like of the tubular portion 36 can be prevented, and the durability of the cover member C6 can be further improved.

  Further, since the protruding end 76e of the outer peripheral wall portion 76 in the protruding direction is located above the case K1 in a longitudinal sectional view, the operation stroke may be longer than usual due to some external factors. Even if it does, the outer peripheral wall portion 76 functions as a stopper, and can protect the case K1 from being subjected to an excessive impact via the operation member S3. Thus, the durability of the electric component 100 can be further improved.

  Further, at least a part of the annular protruding portion 16t provided on the side of the base portion 16 where the cylindrical portion 36 is not provided (the attached portion 500 side) overlaps with the flange portion 11v in plan view, When the electric component 100 is mounted on the mounting portion 500, the projecting portion 16t is urged by the mounting portion 500 with priority and comes into pressure contact with the mounting portion 500. This makes it possible to further secure the close contact structure between the cover member C6 and the mounted portion 500, and further enhance the waterproof function.

  In addition, since the outer peripheral portion of the base portion 16 has an umbrella portion 16a that extends downward and becomes thinner in the extending direction, the electric component 100 is attached to the mounting portion 500. When the umbrella portion 16 is attached to the mounting portion 500, the umbrella portion 16a is pushed upward and outward by the attached portion 500, and is pressed against the attached portion 500. Therefore, the structure of the close contact between the cover member C6 and the mounted portion 500 can be further ensured. Moreover, since the front end side of the umbrella portion 16a is thin, when the cover member C6 is mounted on the mounted portion 500, the air between the base portion 16 and the mounted portion 500 can be easily released, and the cover member C6 can be released. The structure of the close contact between the mounting portion 500 and the mounting portion 500 can be further ensured. With these, the waterproof function can be further enhanced.

  In addition, since the engaging member 71 having the engaging protrusion 71k that can be engaged with the mounted portion 500 is disposed inside the flange portion 11v, a mechanism (an engaging member) for mounting the electric component 100 to the mounted portion 500 is provided. The cover member C6 attached to the flange portion 11v, including 71), can surely cover the attachment hole 500h of the attached portion 500. Thereby, the waterproof performance of the electric component 100 can be further improved.

  Further, since the detection means M5 has the movable contact member 5A operable integrally with the operation member S3 and the fixed contact member 5B capable of contacting 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 coming and going. Moreover, since the detection means M5 is housed in the case K1, waterproofing can be reliably performed. Accordingly, it is possible to provide the electric component 100 having a switch function and a waterproof structure with a simple configuration.

  In addition, 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. Therefore, when the electric component 100 is mounted on the mounting portion 500, the electric component 100 is located on the opposite side of the cover member C6 with the mounting 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 a conventional example in which one terminal (the negative electrode plate 902) is exposed to a severe environment. The first extraction terminal 19 and the second extraction terminal 29 are less likely to rust. Thus, it is possible to provide the electric component 100 having a switch function and a waterproof structure capable of minimizing the occurrence of conduction failure.

Note that the operation member S3, the urging member F4, and the connector housing H8 have the same configuration as in the first embodiment, and a description thereof will be omitted.

  First, the case K21 of the electric component 200 will be described. FIG. 20 is a perspective view in which the cover member C6 shown in FIG. 15 is omitted. FIG. 21 is a perspective view in which the operation member S3 and the urging member F4 shown in FIG. 20 are further omitted. FIG. 22A is a top view as viewed from the Z1 side shown in FIG. 21, and FIG. 22B is a bottom view as viewed from the Z2 side shown in FIG. FIG. 23A is a front view seen from the Y2 side shown in FIG. 21, and FIG. 23B is a side view seen from the X1 side shown in FIG. FIG. 24 is an enlarged view of the R portion shown in FIG.

  As in the first embodiment, the case K21 of the electrical component 200 is manufactured by injection molding using a synthetic resin material such as polybutylene terephthalate resin (PBT), and as shown in FIG. 21; an upper case portion 11 having an opening K1h formed in the Z1 direction; a lower case portion 51 formed on the other side (the Z2 direction side shown in FIG. 21) continuously with the upper case portion 11; And an engaging member 271 extending upward (Z1 direction shown in FIG. 21) from the portion 51.

  When the electric component 200 is mounted on the mounting portion 500, as shown in FIG. 23, the upper case portion 11 is disposed on one side of the mounting portion 500 (the Z1 direction side shown in FIG. 23). At the same time, the lower case portion 51 is inserted into the mounting hole 500h and disposed on the other side (the Z2 direction side shown in FIG. 23) of the mounted 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 injection-molded.

  In the case K21, as shown in FIGS. 18 and 21, a housing portion K1s formed by the upper case portion 11 and the lower case portion 51 is formed continuously with the opening K1h, and as shown in FIG. As described above, the operation member S3 is housed in the housing portion K1s. The case K21 supports the operation member S3 so that the operation member S3 can move in the vertical direction (the Z direction shown in FIGS. 18 and 19).

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

  Next, each component of the case K21 will be described.

  First, as shown in FIG. 23A, the upper case portion 11 of the case K21 projects from the lower case portion 51 laterally (in the X direction shown in FIG. 23A) when viewed from the side. 11t, and a flange portion 11v that protrudes further laterally than the protruding portion 11t. In other words, as shown in FIG. 22B, the protruding portion 11t is formed to protrude outward from the lower case portion 51 when viewed from the lower case portion 51 side in a plan view (bottom view), and the flange portion 11v is formed. As shown in FIG. 22A, is formed over the entire periphery, protruding outward from the outer edge of the upper case portion 11 (case K21) when viewed from the opening K1h side (top view). . Each of the protruding portion 11t and the flange portion 11v has a larger outer shape than the mounting hole 500h, and is not inserted into the mounting hole 500h of the mounted portion 500.

  In addition, as shown in FIGS. 21 and 22 (a), the upper case portion 11 is provided with two peripheral housing portions 11s which are arranged at positions surrounding the housing portion K1s as opposed to each other when viewed from above. ing. As shown in FIG. 22A, the two peripheral accommodation portions 11s penetrate a part of the protruding portion 11t, and the engagement members 271 are provided respectively.

  As shown in FIG. 23, the protruding portion 11t of the upper case portion 11 is opposed to or in contact with one surface of the mounted portion 500 at the edge of the mounting hole 500h of the mounted portion 500, and as shown in FIG. As shown in (2), it is in contact with the cover member C6 (specifically, a base portion 16 described later). In the second embodiment of the present invention, as shown in FIGS. 22B and 23, the protrusions 11t are provided only on both sides in one direction (the X direction shown in FIG. 23A). , Are not provided in a direction orthogonal to one direction (Y direction shown in FIG. 23B), but 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.

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

  Next, as shown in FIG. 23, the lower case portion 51 of the case K21 has a rectangular shape having four surfaces and a box-like shape having a housing portion K1s formed by the upper case portion 11. I have. Further, since the outer wall portion 51w forming the outer periphery of the lower case portion 51 is configured to be smaller than the opening shape of the mounting hole 500h of the mounted portion 500, the lower case portion 51 can be inserted into the mounting hole 500h. When the electric component 200 is mounted on the mounted portion 500, it is disposed on the other side of the mounted portion 500 (see FIGS. 18 and 23).

  Finally, the engagement member 271 of the case K21 can be engaged with the edge of the mounting hole 500h (see FIG. 24) of the mounted portion 500 as shown in FIG. As described above, it has an engaging projection 71k protruding to the side and a grip 271j provided at the upper end extending to above the upper case 11.

  As shown in FIG. 21, two engaging members 271 are provided at positions opposing each other with the housing portion K1s interposed therebetween. As shown in FIG. 11v is provided inside. Thereby, the cover member C6 attached to the flange portion 11v, including the mechanism (engaging member 271) for attaching the electric component 200 to the attachment portion 500, can surely cover the attachment hole 500h of the attachment portion 500. it can. Thereby, the waterproof performance of the electric component 200 can be further improved. Moreover, the electric component 200 according to the second embodiment of the present invention is more flexible in comparison with a mechanism such as a conventional waterproof push switch 900 for a vehicle, which is screwed at a position apart from a hole in the body 950. Since the fitting is performed at the edge of the mounting hole 500h of the mounting portion 500, the mounting portion 500 is securely locked to the mounted portion 500. Thereby, the waterproof performance of the electric component 200 can be further enhanced.

  As shown in FIGS. 16B and 23B, the lower end of the engaging member 271 is connected to an outer wall portion 51w forming the outer periphery of the lower case portion 51. The upper end of the upper case 11 extends upward from the end 51e (upper end) of the concave portion (step portion) of 51w and penetrates the peripheral housing portion 11s as shown in FIGS. (Z1 direction shown in FIG. 1). In particular, also in the second embodiment, as in the first embodiment, the engagement member 271 is provided on the outer wall portion 51w of the lower case portion 51 on the upper case portion 11 side as shown in FIG. The engaging member 271 extends from a bottom surface (end portion 51e) located below the concave portion. Thereby, the engaging member 271 can be disposed further inside as compared with the case where the engaging member 271 extends outward from any one of the outer wall portions 51w and is bent in an L-shape, and downsizing can be achieved. .

  As shown in FIG. 18, the engagement member 271 is formed in a state where a space is provided at a position inside the engagement member 271, and the end portion 51 e of the outer wall portion 51 w (located below the concave portion). (Part) as a fulcrum, so that it can swing toward the accommodation portion K1s while being elastically deformed. That is, it can be said that the engagement member 271 is formed by an elastic piece whose lower end is 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 projection 71k of the engaging member 271 is provided on the lower side (the Z2 direction side shown in FIG. 23) from the upper case section 11 and is arranged on the other side of the mounted part 500. It has been established. And, as described above, the engagement protrusions 71k are provided at positions facing each other with the storage portion K1s interposed therebetween.

  Thus, the engaging member 271 uniformly presses the attached portion 500 by the engaging protrusion 71k. Therefore, the case K21 can be securely fixed to the mounted portion 500 by the engaging projection 71k, and the case K21 can be held without being inclined with respect to the mounted portion 500. Accordingly, the electric component 200 can be securely and easily mounted with a simple configuration, and the tight contact structure between the cover member C6 and the mounted portion 500 is ensured, and the waterproof function is enhanced. Can be.

  In addition, the respective engaging protrusions 71k provided on the two engaging members 271 are arranged on the same circumference and at positions where the circumference is equally divided in plan view. That is, in the second embodiment of the present invention, as in the first embodiment, there are two engaging projections 71k, so the two engaging projections 71k are placed at a position where the circumference is divided in half (opposed position). The configuration was provided.

  Thus, as described above, the two engaging protrusions 71k come into pressure contact with the mounted portion 500 evenly. Therefore, the case K21 can be securely fixed to the mounted portion 500, and the case K21 can be held without being inclined with respect to the mounted portion 500. In the second embodiment of the present invention, two engagement members 271 are provided at opposing positions. However, the configuration is not limited to this, and a configuration in which three or four members are provided may be used. In this case, it is preferable that the plurality of engagement members 271 be disposed in a well-balanced position 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 projection 71k is provided with a contact surface 71t provided facing the plate-shaped attached portion 500 and an outer wall portion 51w of the lower case portion 51 as going upward from below. And a guide surface 71g formed so as to be gradually separated from the guide surface 71g.

  Thus, when the case K21 is inserted into the mounting portion 500, the guide surface 71g smoothly slides along the edge of the mounting hole 500h of the mounting portion 500, and the engagement member 271 moves in the swing direction. It will swing toward the direction. Then, when all of the engaging protrusions 71k are inserted into the mounting holes 500h, the engaging members 271 swing outward in the swing direction, and the contact surface 71t faces the attached portion 500. Become like When the electric component 200 is thus mounted on the mounting portion 500, as shown in FIGS. 18, 23 (a) and 24, the engaging member 271 engages with the mounting portion 500. As a result, the electric component 200 is fixed to the mounted portion 500. That is, so-called snap-in engagement is easily performed.

  Next, as shown in FIG. 23, since the grip portion 271j of the engagement member 271 protrudes upward from the upper case portion 11, the grip portion 271j can be gripped from outside the elastic cover member C6. When the grip portion 271j is gripped, the engagement member 271 tilts (swings) toward the storage portion K1s with the end 51e (upper end) of the lower case portion 51 as a fulcrum. Thus, the engagement member 271 (the grip portion 271j) is operable via the cover member C6.

  Accordingly, when the electric component 200 is mounted on the mounting portion 500, the engaging projection 71k is pivoted from the outside of the cover member C6 to the housing portion K1s side so that the engaging projection 71k is attached to the mounting hole 500h of the mounting portion 500. Then, by returning the swing of the grip portion 271j to the initial state, the engaging projection 71k and the mounted portion 500 can be easily engaged. On the other hand, after the electric component 200 is mounted on the mounting portion 500, the grip portion 271j is swung from the outside of the cover member C6 through the cover member C6 toward the housing portion K1s, so that the engaging protrusion 71k and the mounting portion are connected. The electric component 200 can be easily detached from the mounted portion 500 because the engagement with the electric component 200 can be easily released. Thus, the electric component 200 can be easily attached and detached with a simple configuration. In particular, in the second embodiment, since one set of the engaging members 271 is provided at positions opposing each other with the housing portion K1s interposed therebetween, the grip portions 271j of both the engaging members 271 can be simultaneously grasped, and more detachable. Workability is good.

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

  The cover member C6 of the electric component 200 is formed by transfer-molding synthetic rubber, which is a material having waterproofness and elasticity, and has a base portion 16 formed in a plate shape having a hole 16k, and a hole. An elastically deformable tubular portion 36 extending from an edge of the base portion 16 facing the portion 16k, a lid portion 56 for closing a side of the tubular portion 36 facing the hole portion 16k, and an upper portion from an outer edge of the base portion 16 And an outer peripheral wall 76 formed in a cylindrical shape so as to protrude therefrom.

  Then, the cover member C6 is inserted from the hole 16k (see FIGS. 13B and 14B) to the space inside the cylindrical portion 36, the opening K1h side of the case K21 is inserted, and the case K21 (the upper The case portion 11) covers the opening K1h side. In this 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 11v. Thus, a so-called undercut portion is clearly formed on the cover member C6.

  Accordingly, it is not necessary to provide an undercut portion in the cover member C6 in advance as in the conventional example, and the cover member C6 can be easily used as a member for waterproofing. Thereby, the mold structure for producing the cover member C6 can be simplified, and when the cover member C6 is formed, the cover member C6 can be removed from the mold without excessive pulling. Therefore, shavings are less likely to occur, and it is possible to prevent problems caused by shavings.

  When the electric component 200 is mounted on the mounting portion 500, as shown in FIGS. 18 and 19, the cover member C6 covers the mounting hole 500h, and as shown in FIG. A portion of the cylindrical portion 36 deformed along the outer shape and a portion of the base portion 16 are pressed and held between the flange portion 11v and the attached portion 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.

  Further, a synthetic rubber material made of an opaque material is used for the cover member C6, and it is not apparent from the user side that the grip portion 271j of the engaging member 271 protrudes inside the cover member C6. For this reason, for example, it is difficult for a person other than the person who knows the existence of the engagement member 271 to understand how to remove the engagement member 271, and it is possible to reduce the risk of accidental removal by the user.

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

  First, the base part 16 of the cover member C6 is formed in a ring shape having a cylindrical hole part 16k, and when the electric component 200 is mounted on the mounting part 500, the base part 16 shown in FIGS. 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 so as 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 has sufficient elastic deformation. It is formed so that it can be done.

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

  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 in contact with the outer peripheral portion of the flange portion 11v. It comes to be located between the outer peripheral wall portion 76. Thus, the outer peripheral wall portion 76 protects the cylindrical portion 36 located on the outer peripheral side of the flange portion 11v (extending direction side of the flange portion 11v) from external factors, for example, 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 facing the hole 16k, and a dome-shaped dome portion 56d formed continuously from the cylindrical portion 36 is formed. , And a cylindrical presser portion 56p provided at the top of the dome portion 56d.

  As shown in FIG. 24, the lower portion 56 t of the dome portion 56 d of the lid portion 56 on the cylindrical portion 36 side 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 lower portion 56t faces the step portion 11d of the flange portion 11v of the upper case portion 11, that is, the first regulating portion 11z. And a position opposing the step portion 11d in the lower portion 56t is used as a second restricting portion 56z. Therefore, when the cover member C6 is mounted on the case K21, the first restricting portion 11z and the second restricting portion 56z come into engagement.

  Accordingly, when the cylindrical portion 36 elastically deforms along the outer shape of the flange portion 11v to cover the flange portion 11v, the lid portion 56 is prevented from being deformed by being pulled toward the extension direction side of the flange portion 11v. be able to. That is, since only the tubular portion 36 is further pulled, the tubular portion 36 is extended and attached so as to be more closely attached to the flange portion 11v. Thus, the gap generated between the tubular portion 36 and the flange 11v can be reduced, and the tubular portion 36 can be more closely attached to the flange 11v. Further, when the cover member C6 is attached to the case K21 or when the operation member S3 is operated, it is possible to prevent the cover portion 56 from undesirably expanding and deforming.

  Lastly, 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 (in the Z1 direction shown in FIGS. 13 and 14). ), And is formed in a cylindrical shape so as to surround the cylindrical portion 36. Further, the outer peripheral wall portion 76 is configured to be thicker than the cylindrical portion 36, as shown in FIG. Accordingly, protection of the tubular portion 36 located outside the flange portion 11v from an external factor can be reliably performed. Thus, for example, the occurrence of breakage of the tubular portion 36 can be prevented, and the durability of the cover member C6 can be improved.

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

  FIG. 25 is a view for explaining the detection means M25, the terminal member T7, and the extraction terminal TA29 according to the second embodiment of the present invention. FIG. 25 (a) is a view from the middle of X1 and Y2 shown in FIG. FIG. 25 (b) is an upper perspective view seen from the opposite side to FIG. 25 (a). 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 electric component 200 includes a movable contact member 5A operable integrally with the operation member S3 and two fixed contact members 5C capable of contacting the movable contact member 5A. It is configured to have. The movable contact member 5A and the fixed contact member 5C are made of a metal plate, and are manufactured by performing a cutting process, a bending process, and the like. In the second embodiment of the present invention, the two fixed contact members 5C include 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 detecting means M25 are housed in the case K21.

  Then, when the electric component 200 is assembled, the movable contact member 5A is fixed to the side wall of the base 13 of the operation member S3, and as shown in FIG. Each of the children (a total of four sliders) is disposed at a position where it comes into contact with the first fixed contact portion C15 and the second fixed contact portion C25. As a result, a state where 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 is established.

  When the operation member S3 is pressed downward via the cover member C6, the slider of the movable contact member 5A separates from the first fixed contact portion C15 and the second fixed contact portion C25. I will do it. Thus, the first fixed contact portion C15 and the second fixed contact portion C25 are electrically disconnected, that is, a 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.

  In this manner, in the second embodiment of the present invention, the movable contact members 5A and 5C 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 detection means M25 is configured by bringing the two fixed contact members 5C into and out of contact with each other. The detection means M25 detects the operation of the operation member S3 associated with the operation of the operation member S3, and functions as a switch device that can switch between an open state and a closed state. In addition, since the detection means M25 is housed in the case K21, the cover member C6 can reliably perform waterproofing.

  Next, the terminal member T7 of the electric component 200 includes a board portion T7d formed in a plate shape and a semi-ring shape, and a side end portion T7e extending (pending) substantially vertically from both ends of the semi-ring shape. , Is composed of. Note that the terminal member T7 uses a metal plate, as in the case of 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 disposed so as to be embedded 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. The exposed portion is located on the inner side (the accommodation portion K1s side) of the step portion 11d of the flange portion 11v.

  Further, as shown in FIG. 25A, the board portion T7d is connected to the second fixed contact portion C25 by welding, caulking, or the like, and is in conduction. 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, and as shown in FIGS. 21, 22A and 23A, a case K21. Are respectively accommodated in U-shaped concave grooves K1u formed on the side surface portions of. At this time, the concave end of the side end T7e is exposed to the outside of the case K21.

  Then, when the electric component 200 is mounted on the mounting portion 500, as shown in FIG. 26, the concave edge of the side end portion T7e is configured to contact the mounting portion 500. Note that a portion that can be brought into contact with the mounted portion 500 is an exposed portion T7r of the terminal member T7. That is, the exposed portion T7r is provided on each of the side surface portions of the case K21 opposed to each other with the housing portion K1s interposed therebetween.

  Thus, when the electric component 200 is mounted on the mounting portion 500, the second fixed contact portion C25 is electrically connected to the mounting portion 500 via the terminal member T7. Since the side end portion T7e is formed in a U-shape, the side end portion T7e comes in contact with the attached portion 500 at two places (four places when both sides are combined), and connection stability is further improved.

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

  Thus, 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. Thus, the connection between the terminal member T7 and the mounted portion 500 can be performed by the plurality of exposed portions T7r and the mounted 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 engaging member 271 can be gripped by using the exposed portion T7r as a mark, and when the worker performs the work of detachment, the work is performed. It will be easier.

  Lastly, as shown in FIG. 25, the extraction terminal TA29 of the electric component 200 is formed integrally with the first fixed contact portion C15 of the detection means M25, and as shown in FIGS. 18, 22 (b) and 23 (b). As shown in ()), it is disposed in the connector housing H8. 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 together with the fixed contact member 5C and the terminal member T7 when the case K21 and the connector housing H8 are injection-molded. The surface of the extraction terminal TA29 is plated with silver for 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 configuration described above, the electrical component 200 can have one external terminal (extraction terminal TA29), and from the extraction terminal TA29, the first fixed contact portion C15, the movable contact member 5A, and the second fixed contact. Through the portion C25 and the terminal member T7, conduction can be made to the mounted portion 500 (becoming a ground).

  When the electric component 200 is mounted on the mounting portion 500, the extraction terminal TA29 is positioned on the opposite side of the mounting member 500 from the cover member C6, and the side surface of the case K21. The exposed portion T7r that is exposed from is located 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. As a result, occurrence of conduction failure can be reduced as much as possible.

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

  In the electric component 200 according to the second embodiment of the present invention, the cover member C6 is provided with the base portion 16 formed in a plate shape having the hole 16k, 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 for closing the side of the cylindrical portion 36 facing 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 configured to be mounted. For this reason, it is not necessary to provide an undercut portion in the cover member C6 in advance as in the conventional example. As a result, the mold structure for manufacturing the cover member C6 can be simplified, and unnecessary removal when removing the cover member C6 from the mold does not occur. And it is possible to prevent the occurrence of problems due to shavings. Therefore, it is possible to provide the electric component 200 having a waterproof structure with a simple configuration.

  Also, a part of the cylindrical part 36 and a part of the base part 16 deformed along the outer shape of the flange 11v are pressed and sandwiched by the flange 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. For this reason, it is possible to reliably perform waterproofing with a simple configuration in which an undercut-shaped portion is not provided on the cover member C6 as in the conventional example.

  When attaching the cover member C6 to the case K21, the first regulating portion 11z provided on the flange portion 11v of the case K21 and the second regulating portion 56z provided on the cover portion 56 of the cover member C6 engage. Therefore, when the cylindrical portion 36 elastically deforms 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 extension direction side of the flange portion 11v. be able to. For this reason, the gap generated between the cylindrical portion 36 and the flange portion 11v can be reduced, and the cylindrical portion 36 can be more closely attached to the flange portion 11v. Thereby, the waterproof function can be further enhanced. In addition, 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.

  In addition, since a part of the cylindrical portion 36 is located between the outer peripheral wall portion 76 having a greater thickness than the cylindrical portion 36 and the flange portion 11v of the case K21, the outer peripheral side of the flange portion 11v (the extension of the flange portion 11v). The tubular portion 36 located on the (outward side) can be protected from external factors, for example, physical impact. Thus, for example, the occurrence of breakage of the tubular portion 36 can be prevented, 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 mounted portion 500 is arranged inside the flange portion 11v, a mechanism (an engaging member) for mounting the electric component 200 to the mounted portion 500 is provided. 271), the cover member C6 attached to the flange 11v can reliably cover the attachment hole 500h of the attached portion 500. Thereby, the waterproof performance of the electric component 200 can be further improved.

  Further, an engaging member 271 connected to the outer wall portion 51w of the lower case portion 51 of the case K21 and elastically deformed is provided with a grip portion 271j extending above the upper case portion 11 in a side view, as an upper end portion. 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 mounted on the mounting part 500, the engaging projection 71k is pivoted from the outside of the cover member C6 to the housing part K1s side so that the engaging projection 71k is attached to the mounting hole 500h of the mounting part 500. Then, by returning the swing of the grip portion 271j to the initial state, the engaging projection 71k and the mounted portion 500 can be easily engaged. On the other hand, after the electric component 200 is mounted on the mounting portion 500, the grip portion 271j is swung from the outside of the cover member C6 through the cover member C6 toward the housing portion K1s, so that the engaging protrusion 71k and the mounting portion are connected. The electric component 200 can be easily detached from the mounted portion 500 because the engagement with the electric component 200 can be easily released. Thus, the electric component 200 can be easily attached and detached with a simple configuration.

  In addition, since the engaging member 271 extends from the bottom surface of the concave portion provided in the outer wall portion 51w of the lower case portion 51, the engaging member 271 extends outward from any of the outer wall portions 51w and bends into an L-shape. As compared with the case, the engagement member 271 can be arranged further inside. Therefore, the engaging member 271 can be easily extended into the upper case portion 11, and the grip portion 271j can be easily housed in the cover member C6.

  In addition, since the engaging members 271 are provided at positions opposing each other with the housing portion K1s interposed therebetween, the engaging members 271 (the engaging protrusions 71k) uniformly press the mounting portion 500. Therefore, the case K21 can be securely fixed to the mounted portion 500 by the engaging projection 71k, and the case K21 can be held without being inclined with respect to the mounted portion 500. Accordingly, the electric component 200 can be securely and easily mounted with a simple configuration, and the tight contact structure between the cover member C6 and the mounted portion 500 is ensured, and the waterproof function is enhanced. Can be.

  Further, since the cover member C6 is an opaque material, it is difficult to see from the user side that the grip portion 271j of the engaging member 271 protrudes inside the cover member C6. For this reason, for example, it is difficult for a person other than the person who knows the existence of the engagement member 271 to understand how to remove the engagement member 271, and it is possible to reduce the risk of accidental removal by the user.

  Further, since the detecting means M25 has the movable contact member 5A operable integrally with the operation member S3 and the fixed contact member 5C capable of contacting 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 coming and going. Moreover, since the detection means M25 is housed in the case K21, it is possible to reliably perform waterproofing. Accordingly, it is possible to provide the electric component 200 having a switch function and a waterproof structure with a simple configuration.

  In addition, the first fixed contact portion C15 is electrically connected to the extraction terminal TA29 for electrical connection with an external device, and the second fixed contact portion C25 has an exposed portion T7r that can abut on the mounted portion 500. Since the terminal member T7 is electrically connected to the terminal member T7, the lead terminal TA29 is electrically connected to the mounting 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. Therefore, the number of external terminals (extraction terminals TA29) in the electric component 200 can be reduced to one.
