Description

  The present invention relates to a seat switch for operating a power seat of a vehicle, and more particularly, to reduce the weight and cost thereof.

  Conventionally, as this type of sheet switch, for example, one described in Patent Document 1 is known. The seat switch in the same document moves the power seat back and forth or up and down by rotating the motor that drives the power seat of the vehicle forward or backward, or reclines the backrest of the power seat or returns it to its original posture. It is used when operating the power seat.

  Conventionally, the switch base constituting the seat switch as described above has a wiring line for a motor for driving a power seat, a wiring line for a power source and a ground, and further, these wiring lines are connected to a motor, a power source and a ground. A connector terminal for connection is provided. Such wiring lines and connector terminals are integrally formed as a single part from a single metal plate and installed on the switch base.

  However, according to the conventional sheet switch, the wiring line installed in the switch base is integrally formed as a single part from the same metal plate as the connector terminal as described above, and thus has the same thickness as the connector terminal. It is inevitable. Therefore, when it is necessary to make the connector terminal standard, for example, a 0.6 mm thick copper plate, the wiring line installed on the switch base is also made of a 0.6 mm thick copper plate, which is expensive and heavy copper. A large amount of material is used, which increases the overall weight of the switch and increases the cost.

Japanese Patent Laid-Open No. 10-308140

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a lightweight and low-cost seat switch.

  In order to achieve the above object, the present invention provides a switch base on a switch base for operating a power seat of a vehicle, a wiring line made of a metal plate connected to a fixed contact of the switch part, and the wiring In a sheet switch comprising a connector terminal made of a metal plate connected to a line, the wiring line is formed by punching from a metal plate that is half the thickness of the connector terminal, and the connector terminal is connected to the wiring line It is characterized by having a double structure in which an elongated plate-like member connected to the wiring line is punched from the same metal plate, and the ends of the elongated plate-like member are bent and overlapped.

  In the present invention, the connector terminal may employ a configuration in which a bent tip portion is embedded in the switch base. According to such a configuration, since the bent tip portion is embedded in the switch base, it is possible to effectively prevent a problem that the tip portion is caught on the connector side.

  In the present invention, as described above, as a specific configuration of the wiring line, the wiring line is formed by punching from a metal plate having a thickness that is half that of the connector terminal. As a configuration, the connector terminal adopts a double structure in which an elongated plate-like member connected to the wiring line is punched from the same metal plate as the wiring line, and the tip of the elongated plate-like member is bent and overlapped. did. For this reason, for example, when a thickness of 0.6 mm is required as a standard for the connector terminal, only the connector terminal has a thickness of 0.6 mm as specified, and the wiring line made of a metal plate has a thickness of 0.3 mm. Therefore, it is possible to significantly reduce the expensive and heavy metal portion in this type of seat switch, and to obtain operational effects such as reducing the weight and cost of the seat switch.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  1 is an external view of a seat switch according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the seat switch of FIG. 1, FIG. 3 is a wiring diagram of the seat switch of FIG. FIG. 5 is an explanatory view of a base constituting the seat switch of FIG. 1.

  In the present seat switch S of FIG. 1, the switch base 1 of FIG. 5 and the cover 2 of FIG. 4 fixed over the switch base 1 constitute a single casing, and the first to thru as shown in FIG. The third switch portions S1, S2, and S3 and actuators A1 and A2 that operate these switch portions are accommodated.

  The first switch portion S1 is used when the power seat reclining operation motor M1 is rotated forward and backward to recline or restore the power seat.

As a result, the front end portion of the first movable contact 5 </ b> A comes into contact with the third fixed contact 33, and the rear end portion of the first movable contact 5 </ b> A is lifted from the second fixed contact 32. At the same time, the second movable contact 5B tilts backward with the fourth fixed contact 34 as a fulcrum, and as a result, the front end portion of the second movable contact 5B is lifted from the fifth fixed contact 35, and the second movable contact 35 The rear end portion of 14B comes into contact with the sixth fixed contact 36.

  As described above, the third fixed contact 33 that is in contact with the front end portion of the first movable contact 5A and the sixth fixed contact 36 that is in contact with the front end portion of the second movable contact 5B are both. Since it is connected to the ground via the ground wiring line LG and the ground connector terminal CG, it is at the ground potential. From the third and sixth fixed contacts 33 and 36 having the ground potential to the first and second movable contacts 5A and 5B, the first and fourth fixed contacts 31 and 34, the motor wiring lines LE and LF, and Since the ground potential is applied to both terminals of the reclining operation motor M1 via the motor connector terminals CE and CF, the reclining operation motor M1 does not rotate and is stopped.

<Description of operation when the reclining knob is tilted forward>
When the reclining knob 15A in the neutral position is tilted backward as shown in FIG. 1, the first and second protrusions 14A and 14B slide backward. At this time, as shown in FIG. 10C, the first protrusion 14A moves over the fulcrum (first fixed contact 31) of the first movable contact 5A and slides backward, so that the first movable contact 5A is As a result, the front end portion of the first movable contact 5 </ b> A is lifted from the third fixed contact 33 and the rear end portion of the first movable contact 5 </ b> A is in contact with the second fixed contact 32. On the other hand, the second protrusion 14B is positioned behind the fulcrum (fourth fixed contact 34) of the second movable contact 5B from when the reclining knob 15A is in the neutral position as shown in FIG. 10B. The second movable contact 5B maintains the posture when the reclining knob 15A is in the neutral position because it only slides backward from this position. That is, the second movable contact 5B is tilted backward with the fourth fixed contact 34 as a fulcrum, the front end of the second movable contact 5B is lifted from the fifth fixed contact 35, and the rear end of the second movable contact 5B. The part is in contact with the sixth fixed contact 36.
