Abstract

PURPOSE:To form a part, which is related to a sliding control member such as a select lever, compact and light in weight at a low cost by fitting a turning rod in a long hole of a slider, and inclining the direction of the long hole to the direction, in which the turning rod is inclined for operation. CONSTITUTION:A long hole 4 is formed in a slider 2, and fitted to a fitting point P of a turning rod 5. A supporting point O of the turning rod 5 is set in a printed circuit board 1 near the movement line of the slider 2, and the direction of the long hole 4 is inclined in the direction, in which the turning rod 5 is inclined for operation when the slider 2 is moved. With this structure, the slider 2 of a sliding control unit such as a slide switch part, which is formed with a printed circuit, can be moved at an amplitude larger than the amplitude of the turning rod 5 even in the case where a short turning rod 5, which is turned around of the supporting point O at a short distance, is used. Consequently, an associated part of a select lever of an automatic transmission automatic or the like can be formed compact and light in weight.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for rotating a slider by a rotating rod in order to improve the operability of a slide control member such as a slide switch or a slide volume formed into a printed circuit.

[0002]

2. Description of the Related Art Conventionally, as a rotary operation device for a slide switch, there is a device as shown in FIG. 6, for example. In this conventional technique, a plurality of conductive patterns 1a fixed on an insulating substrate 1 of the slide switch are fixed. Slider along the point contact
2 is a slide switch for sliding the movable contact piece 2a together with the movable contact piece 2a, and a fulcrum O of a rotating rod 5 which is partially engaged with an upright elongated hole 4 or an elongated groove formed in the slider 2 at an engaging point P is a body. This is a rotation operating device for a slide control member, which is provided so as to be separated from the lower portion by a distance d and is formed so that the elongated hole 4 or the elongated groove is orthogonal to the moving direction of the slider 2.

[0003]

According to the above-mentioned conventional technique, the slider 2 can be slid by the rotating force of the pivoting rod 5 having a fixed fulcrum, so that the slider 2 can be securely held at hand.
Although it has the advantage that it can be moved finely or greatly even with one hand, the long hole 4 or long groove of the slider 2 is provided orthogonally to the sliding trajectory of the slider 2, so the sliding distance (swing The width) is equal to the moving width of the engagement point P.

Therefore, when this one is used in association with a recent automatic vehicle select lever,
In order to ensure reliable and stable operation of a large-current type slide switch with multiple poles and multiple contacts, it is necessary to secure the contact distance, so the long pivoting rod that separates the fulcrum of the select lever from the slide switch itself by a distance and dimension d. Therefore, there is a problem that it is necessary to increase the slider movement width, and all the parts related to the select lever are large and heavy, and the structure is complicated and expensive.

In order to eliminate the above-mentioned problems, the present invention rotates a movable contact piece of a slide control member such as a slide switch formed of a conductive pattern formed on a printed circuit board so as to rotate at a fulcrum close to the slider. Even if a rod is used, the object is to make the portion related to the sliding control member such as around the select lever small, lightweight and inexpensive by amplifying the swing and moving it.

[0006]

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is to form an operating device for sliding a movable contact piece elastically in contact with a plurality of conductive patterns formed on a printed circuit board with a slider. The printed circuit board is pivotally supported at a pivot point of a pin or the like on the printed circuit board or the chassis on which the circuit is attached by engaging the elongated hole or slot formed at the engaging point at the engaging point. Alternatively, it can be achieved by inclining the direction of the long groove in the inclination direction of the rotating rod with respect to the movement path of the slider.

[0007]

The fulcrum of the rotary rod is set at the pivotal support portion arranged in the penetrating direction of the elongated hole or in the depth direction of the elongated groove, and the direction of the elongated hole or the elongated groove is set as the fulcrum with respect to the movement trajectory of the slider. Since the slider is tilted in the tilting direction of the line connecting the engagement point, that is, in the tilting direction of the operation of the rotary rod,
2 can be slid in the arrangement direction of the fixed contacts of the insulating substrate 1 by the turning force of the rotating rod 5 which is engaged with the long hole 4 or the long groove 4a at the engagement point P such as a pin. The conduction between them can be controlled by the movable contact piece.

Then, the direction line of the long hole 4 or the long groove 4a,
Let θ be the angle between the slider 2 and the moving direction line, and
When the horizontal movement width of the engagement point P due to the rotation of the slider is W, the slider sliding width WS is WS = W / Sin θ (1) Therefore, when θ = 45 °, WS = 1.4142
It is 1356 × W, and exhibits an amplification effect of about 1.4 times.

[0009]

For example, it is tilted to the right in the direction of tilt when operating 5.

It should be noted that instead of the long hole 4 in the above embodiment, the long groove 4a may be formed in the slider 2 and the pin of the rotary rod 5 may be engaged with the same effect. In FIG. 2, a symbol S indicates a spring for elastically contacting the movable contact piece 2a with the conductive pattern 1a, and a symbol 1c indicates a printed circuit pattern extended from the plurality of conductive patterns 1a, 1a. .

The structure of the present invention is as described above. Next, an example of its use will be described in detail. In this invention, the rotating rod 5
As shown in FIG. 2, the fulcrum O is set at the pivotal support portion 6 such as a pin protruding from the printed circuit board 1 near the movement line of the slider 2, and the direction of the long hole 4 or the long groove 4a is set as shown in FIGS. As described above, the slider 2 is tilted in the direction in which the line connecting the fulcrum O and the engagement point P is tilted more than in the direction orthogonal to the moving direction, that is, in the tilting direction when the rotating rod 5 is operated.
As shown by the chain line in FIGS. 1 and 3, the slider 2 is arranged in the arrangement direction of the fixed contacts of the insulating substrate 1 by the turning force of the rotary rod 5 which is engaged with the elongated hole 4 or the elongated groove 4a at the engaging point P such as a pin.

Since the line connecting the fulcrum O and the engagement point P is tilted with respect to the locus, the slider 2 of the sliding control unit such as a slide switch unit in the form of a printed circuit can be rotated at the fulcrum O near it. Even if the paddle pivoting rod 5 is used, it can be moved by amplifying it more than the swing width, and the portion related to the so-called sliding control member around the so-called automatic vehicle select lever can be made small, lightweight and inexpensive. .

Further, according to the present invention, the sliding control portion of the printed circuit board 1 is not greatly protruded by an obstacle such as a slider operation piece, so that there is an effect that the degree of freedom of partial arrangement around the sliding control portion is improved.
