Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination switch provided near a steering handle.

[0002]

2. Description of the Related Art Generally, a combination switch and a steering lock member are separately provided on a shaft portion of a steering handle.

[0003] A lighting switch member and a wiper switch member are mounted on the combination switch. On the other hand, the steering lock member includes a key cylinder and an ignition switch in addition to the steering lock mechanism.

[0004] By the way, recently, the presence or absence of key insertion,
It is desired to provide an additional mechanism for determining whether the key is a legitimate key. For this reason, the steering lock member is provided with a key detection switch for detecting the presence or absence of a key insertion and a key determination sensor for determining whether or not the key is a legitimate key.

[0005]

However, in the prior art, the combination switch and the steering lock member are separately provided as described above, and their functions are independent from each other.
Therefore, it is necessary to use expensive harnesses and connectors for transmitting signals detected by the key detection switch and the key determination sensor. Then, a process of extending a harness or the like to a predetermined position and electrically connecting the harness is required, and workability is poor.
Reduction is desired.

Accordingly, the present invention provides a combination switch which incorporates at least a part of an additional mechanism of an ignition switch mechanism provided on a steering lock member, and which can be electrically connected with a simple configuration at a low cost. As an issue.

[0007]

According to the present invention, there is provided a combination switch in which a substrate is accommodated in a casing provided on an outer periphery of a shaft portion of a steering handle. A steering lock member having an ignition switch mechanism is attached, and at least a part of an additional mechanism of the ignition switch mechanism is provided on the substrate.

The additional mechanism provided on the substrate may include a key lighting bulb, a key detection switch, and an immobilizer antenna.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a shaft portion 2 of a steering handle 1.
2 shows a state in which the combination switch 3 and the steering lock member 4 are mounted on the outer periphery of.

As shown in FIG. 2, the combination switch 3 has a bearing 6 formed at the center of the casing 5 and located on the outer periphery of the shaft 2 of the steering handle 1. Openings 7a and 7 are provided on the lower surface and both side surfaces of the casing 5.
b and 7c are formed respectively. Side opening 7b,
7c is formed so as to open obliquely upward, and includes a lighting switch member 8 and a wiper switch member 9.
Is easy to install. The casing 5 accommodates an internal substrate 10 through a lower surface opening 7 a, and the lower surface opening 7 a is closed by a lower lid 11.

As shown in FIG. 2, the internal substrate 10 includes a first internal substrate 10a and a second internal substrate 10b disposed at a predetermined interval from the first internal substrate 10a.

The first internal substrate 10a is substantially U-shaped, and first and second contact portions 13 and 14 are formed on the insert terminals 12 at both upper ends by plating the pattern. The outer edge of the insert terminal 12
It is inclined so that it gradually approaches toward the upper end. Thereby, when the first internal substrate 10a is inserted into the casing 5 from the lower surface opening 7a and attached,
The first contact portion 13 and the second contact portion 14 are formed in the side opening 7.
b, 7c.

The second internal board 10b has a recess 15 along the outer periphery of the shaft 2 of the steering handle 1, on which various electronic components are mounted. The electronic components to be mounted include a key illumination bulb 1 conventionally provided on a steering lock member 4 as an additional mechanism for an ignition switch.
6, a key detection switch 17, an immobilizer antenna, and the like. The key illumination bulb 16 and the key detection switch 17
It protrudes toward a steering lock member 4 described later. The key illumination bulb 16 illuminates the key insertion slot at night. The key detection switch 17 is turned on by a rod 19 protruding when a key is inserted into a key cylinder 18 to be described later, and detects the presence or absence of the key. The second internal substrate 10b itself receives a signal from the key, serves as an immobilizer antenna used to determine whether the key is authentic, and is used to prevent theft. You. In addition, the second internal substrate 10b can be used for a keyless function, a safety function, and the like. Note that the keyless function refers to a function of locking or unlocking a door with a remote controller provided for a key.

The internal substrate 10 is provided with a casing 5
Is connected to a control device (not shown) via a connector 5a provided in the control unit. That is, the connector 5a
Only the first internal substrate 10a and the second internal substrate 1 incorporating a part of the additional mechanism of the steering lock member 4
0b can be transmitted and received.

The steering lock member 4 has a key cylinder 18 and is mounted adjacent to the combination switch 3. The key cylinder 18 is provided with a rod 19. When a key is inserted into the key cylinder 18, the rod 19 protrudes from the outer peripheral surface thereof, and turns on the key detection switch 17 provided on the second internal substrate 10 b. Further, an ignition switch 20 is provided at an end of the key cylinder 18, and a predetermined signal is generated by rotating a key inserted into the key cylinder 18.

[0017]

As is clear from the above description, according to the combination switch of the present invention, a part of the additional mechanism of the ignition switch mechanism is incorporated in the built-in board, so that the steering lock is different from the conventional one. Expensive harnesses and connectors required for members can be dispensed with, and mounting workability is improved.
