Further, the planar side surface (the side surface visible on the left side) that is visible in front of the case 15 in FIG. 2 is the front side of the switch device 1, and the opposite side surface is the rear side of the switch device 1.

  The switch device 1 is a push-type switch device for performing a start or stop operation of a motor (for example, an engine or a motor) of a vehicle. The switch device 1 includes a substrate 11, a connector 12, a rubber contact 13, a bobbin 14, a case 15, a slider 16, a knob 17, a cover 18, and a ring 19.

  The board 11 is a control board for controlling the switch device 1. The board 11 is electrically connected to one end of the connector 12, and the other end of the connector 12 is inserted into a connection port 15 </ b> A formed at the lower end of the case 15. The board 11 transmits / receives a signal to / from an external device via the connector 12 or receives power from an external power source. For example, the board 11 outputs a signal indicating the contact state of the switch device 1 via the connector 12, or a portable device for authentication of a vehicle provided with the switch device 1 (for example, a key fob). ) Input / output of signals to be transmitted / received, or output of the authentication result of the portable device. In addition, the substrate 11 performs wireless communication with the portable device via the coil antenna 21 (FIG. 6) provided on the bobbin 14 or supplies power to the coil antenna 21.

  The rubber contact 13 is provided with a movable contact (described later with reference to FIG. 5), and is attached on the surface of the substrate 11 provided with a fixed contact (described later with reference to FIG. 3). Further, a ring-shaped bobbin 14 is attached to the substrate 11 with the rubber contact 13 interposed therebetween. A coil antenna 21 is wound around the ring-shaped side surface of the bobbin 14. The coil antenna 21 is used for wireless communication with the portable device described above, and supplies power supplied from the outside via the connector 12 and the substrate 11 to the portable device in a non-contact manner.

  When a pressing operation is performed on the knob 17, the protrusions 41 a and 41 b of the rubber contact 13 are pushed in by the slider 16 integrated with the knob 17. Then, the protrusions 41a and 41b are pushed from above and deformed, whereby the protrusions 46a and 46b are inserted into the recesses 42a and 42b, respectively. Further, when the protrusions 41a and 41b are pushed in from above and the movable contacts 47a and 47b at the lower ends of the protrusions 46a and 46b reach the lower ends of the recesses 42a and 42b, the substrate disposed below the recesses 42a and 42b. 11 fixed contacts 33a and 33b. As a result, the two separated wiring patterns constituting the fixed contacts 33a and 33b are electrically connected, and the contacts are turned on.

[Assembly Method of Switch Device 1]
Next, an assembly method of the switch device 1 will be described with reference to FIGS.

  First, as shown in FIG. 7, the rubber contact 13 is attached to the surface of the substrate 11 on which fixed contacts 33 a and 33 b (not shown in FIG. 7) are provided. At this time, the protrusions 43a and 43b of the rubber contact 13 are inserted into the notches 31a and 31b of the substrate 11, respectively. The position of the rubber contact 13 is fixed in a state where the fixed contacts 33a and 33b of the substrate 11 and the movable contacts 47a and 47b (not shown in FIG. 7) of the rubber contact 13 face each other. In this way, the fixed contacts 33a and 33b and the movable contacts 47a and 47b can be aligned easily and reliably, and the occurrence of contact failure can be prevented.

  Further, as shown in FIG. 8, the fitting holes 32 a and 32 b of the substrate 11 are exposed without being covered with the rubber contact 13 by the notches 44 a and 44 b of the rubber contact 13.

  Next, the bobbin 14 is attached to the surface of the substrate 11 where the fixed contacts 33a and 33b (not shown in FIG. 8) are provided so as to sandwich the rubber contact 13 therebetween. Thereby, the board | substrate 11 (and connector 12), the rubber contact 13, and the bobbin 14 are assembled into one, and become the integrated component (henceforth the assembly component A).

  At this time, the fitting claws 51a and 51b protruding downward from the left and right inner side surfaces of the bobbin 14 are fitted into the fitting holes 32a and 32b of the board 11, and the board 11, the rubber contact 13, and the bobbin. 14 are fixed to each other. That is, the bobbin 14 is firmly fixed on the substrate 11 without being detached from the substrate 11 or rattling. Moreover, by fixing the board | substrate 11 and the bobbin 14, the rubber contact 13 pinched | interposed between both is also fixed firmly, without removing from the board | substrate 11 and rattling. Therefore, it is possible to prevent the rubber contact 13 from being misaligned during use of the switch device 1 and causing a contact failure. Further, the bobbin 14 can be easily attached to the substrate 11.

  Furthermore, as shown in FIG. 9, in the state where the substrate 11, the rubber contact 13, and the bobbin 14 are integrated, the upper ends of the protrusions 41a and 41b of the rubber contact 13 are the upper ends of the bobbin 14 (opposite to the substrate 11). Projecting above the edge of the side). Accordingly, when the knob 17 is pushed in, the protrusions 41a and 41b can be pushed in by the slider 16 integrated with the knob 17.

  Next, the assembly part A in which the board 11 (and the connector 12), the rubber contact 13, and the bobbin 14 are integrated is inserted from the open end of the case 15 and attached in the case 15. At this time, the fitting claws 52a to 52d formed so as to extend downward from the four corners of the upper surface of the bobbin 14 are horizontally long fitting recesses 61a to 61d formed at the upper four corners of the inner side surface of the case 15. 61d is fitted. In FIG. 9, the fitting claw 52c, the fitting recess 61a, the fitting recess 61b, and the fitting recess 61d are not shown.

  Thereby, the assembly part A is firmly fixed in the case 15 without detaching from the case 15 or rattling. Moreover, since the board | substrate 11, the connector 12, the rubber contact 13, and the bobbin 14 are accommodated in the case 15 in the integrated state, attachment becomes very easy.

  Next, as shown in FIG. 10, the upper end portion (open end side) of the case 15 is inserted into a component (hereinafter referred to as an assembly component B) in which the slider 16, the knob 17 and the cover 18 are integrated. In addition, the slider 16 and the knob 17 are attached in the cover 18 so that it can slide to an up-down direction (pressing direction).

  At this time, the horizontally long fitting claws 62a to 62e formed at the four corners of the outer side surface of the case 15 and the upper part of the rear side are fitted into the fitting holes formed at the four corners of the cover 18 and the lower part of the side surface of the rear side. It fits in 81a thru | or 81e. In FIG. 10, the fitting claws 62a, the fitting claws 62b, and the fitting claws 62e are not shown.

  Thereby, the cover 18 is firmly fixed to the upper part of the case 15 without being detached from the case 15 or rattling. Further, the cover 18 can be easily attached to the case 15. Furthermore, a combination of the slider 16 and the knob 17 can slide in the direction (vertical direction) perpendicular to the surface of the substrate 11 toward the open end of the case 15 in the space formed by the case 15 and the cover 18. Attached to.

  Finally, as shown in FIG. 11, the ring 19 is put on the cover 18. At this time, fitting claws 82a to 82d (but fitting claws 82b to 82d are not shown) formed so as to protrude downward from the four corners of the upper end of the cover 18 are directed downward from the four corners of the ring 19. The ring 19 is fixed to the cover 18 by fitting into fitting holes 91 a to 91 d (where fitting holes 91 b and 91 d are not shown) formed so as to protrude.

  As described above, by assembling the substrate 11 (and the connector 12), the rubber contact 13, and the bobbin 14 in the case 15 in an integrated state, the assembly of the switch device 1 is simplified. Further, by sandwiching the rubber contact 13 between the substrate 11 and the bobbin 14 and fixing them firmly, the positional deviation between the fixed contacts 33a, 33b and the movable contacts 47a, 47b can be prevented, and the occurrence of contact failure can be prevented.

<2. Modification>
