Abstract

PURPOSE:To apply click action to a knob operation by securing in parallel a plurality of fixed conductors serving as those of a slide switch under an insulating base with spaces therebetween. CONSTITUTION:A knob 4 is projected outward a hole 3 board in an upper plate 2 of an insulating base 1 formed in an almost U-shaped cross section. An insulative slide body 5 is movably disposed inside the recess portion of the insulating base 1. Under the slide body 5, there is provided a movable curved projecting conductor 7 projected by a spring 6. A plurality of fixed conductors 8 capable of sliding in contact across the movable projecting conductor 7 are secured in parallel under the insulating base 1 with spaces therebetween. Accordingly, a part of the movable curved projecting conductor 7 operated by the knob 4 drops with a click in the space between the fixed conductors 8 by the effect of a resilient force of the spring 6, to conduct shortcircuiting across the adjacent fixed conductors 8, thereby turning on a switch. Therefore, click action can be applied to a knob operation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slide switch, and more specifically, a movable curved conductor is used as a movable contact piece in the slide switch, and a movable curved conductor is used as a movable contact piece in the slide switch. The present invention relates to a slide switch in which a plurality of narrow conductive plates, so-called bus bars, conductor pipes, or conductor rods are directly arranged side by side and used as fixed conductors that come into sliding contact.

[Prior art] As a general slide switch, for example, the
There is one described in Japanese Patent No.-23681.

This conventional technology is a switch in which switching is performed by swinging a movable contact piece from side to side, and the ears provided at the center of both sides of the movable contact piece are half-moon-shaped or V-shaped, and the movable contact piece is placed on the switch. The movable contact piece receiver is formed of a thin elastic plate, and the left and right rising surfaces of the receiver are bent inward at an acute angle, and bent surfaces are formed in the notched portions of the left and right rising surfaces of the receiver. [Problem to be Solved by the Invention] A device for preventing falling off of a movable contact piece, which is characterized in that an inclined surface is formed on the upper part of the rising surface, and the receiving body holds the movable contact piece [Problem to be Solved by the Invention] The movable contact piece is held between conductive receivers having a square cross section to prevent the movable contact piece from coming out from the receiver. This is a slide switch that moves toward and away from a fixed contact piece by making a see-saw movement using a magnetic receptor as a fulcrum.

Therefore, there are many current paths such as the lead wire extending from one pole of the power supply → crimped terminal → conductive receiver → movable contact piece → fixed contact → swaged terminal → lead wire → load → other pole of the power supply. As a result, current flows through the contact part and the crimped terminal, and when used in a current path with a large current even at a low voltage, there is a large amount of heat generated due to Joule heat due to the contact resistance of the contact part and the crimped part of the crimped terminal, and as described above. Since many parts and caulking methods are used in the process, there are problems in that the structure is complicated, difficult to assemble, and costs are high.

In order to eliminate each of the above-mentioned problems, this invention provides a fixed conductor in a slide switch with a plurality of narrow conductive plates called bus bars, a metal pipe, a conductive rod, etc., in parallel. The movable conductor that falls across the space between the conductors is used as a switch to establish continuity between each fixed conductor, and the purpose is to eliminate the need for click action members and the need for caulking parts and lead wires. shall be.

"Means for Solving the Problems" The object of the invention described above is to make a knob protrude outside from a hole in the upper plate of an insulating base formed into a substantially Π-shaped cross section, and to install an insulating sliding body in a recess of the insulating base. A movable conductor protruding with a spring is disposed at the bottom of the sliding body, and a plurality of fixed conductors that slide over and in contact with the movable conductor of the parentheses are arranged in spaces below the insulating base. This is achieved by fixing them in parallel.

Note that a conductor ball may be used as the movable educational conductor.

Furthermore, a plurality of fixed conductors may be fixed in parallel to the lower part of the insulating base by embedded fixing grooves.

[Function] By providing a plurality of round pipe-shaped conductors, a plurality of conductor rods, or a plurality of vertically arranged conductive plates in parallel as the fixed conductors of the slide switch, the switch can be operated with a knob in the space between these fixed conductors. A part of the movable conductor snaps down due to the elasticity of the spring, straddles the fixed conductors on both sides, and short-circuits, turning on the switch.

A portion of the movable educational conductor operated by the knob elastically snaps into the space between the movable conductors, thereby imparting a click action or snap action to the operation of the knob as a slide switch.

In addition, by operating the knob, the movable conductor can be removed from the space above to turn off the switch, or by dropping part of the movable conductor into the space between other fixed conductors, single-pole, double-throw, or
It serves as a double-pole, double-throw switch.

Furthermore, the conductive pipe, conductive rod, or conductive plate used as a fixed conductor can be integrally molded into a narrow conductive plate, that is, a bus bar, so the fixed conductor can be directly connected to other electrical components or circuit patterns via the bus bar, etc. It can be connected, and there is no need for caulking or lead wires.

[Example] Examples will be described with reference to the drawings.

First, as shown in FIGS. 1 and 2, the basic structure of the present invention is that a rectangular hole is formed approximately in the center of an upper plate 2 of an insulating base 1 made of plastic or the like and having an approximately Π-shaped cross section as shown in FIG. 3
As shown in FIGS. 3 and 7, an insulating sliding body 5 made of plastic or the like is movably provided in the recess 1a of the insulating base 1 with a knob 4 protruding outward.

A movable educational conductor 7, such as a metal conductor ball, protruded by a spring 6 is arranged at the lower part of the sliding body 5 so as to move together with the knob 4, and a fourth As shown in FIGS. 5 and 6, a plurality of fixed conductors 8.8 that are in sliding contact are fixed in parallel to the lower part of the insulating base 1.

Further, as the movable educational conductor 7, a conductor ball may be used as shown in each figure, and furthermore, an inverted Ω-shaped or U-shaped conductive piece may be used.

Further, the plurality of fixed conductors 8 can be fixed to the lower part of the insulating substrate 1 by being firmly clicked into the embedded fixing grooves 9 as shown in each figure, but they may also be fixed in parallel using a pressing plate 11.

In addition, when the fixed conductors 8, 8 are round pipe-shaped as in the illustrated example, by inserting a so-called girder-shaped plug-in connection protrusion into the hole, it is possible to wire to other components via the lead wire etc. can do.

Next, the assembly procedure of this slide switch will be explained.

First, among the parts shown in FIGS. 1, 3, and 7, a spring is inserted into the recess 4a of the knob 4 provided approximately in the center of the hollow rectangular parallelepiped sliding body 5 made of plastic. The movable conductor 7 is inserted into the recess 4a with the spring 6 interposed therebetween, and the knob 4 is inserted into the hole 3 provided in the upper plate 2 of the recess 1a of the insulating base 1, so that the movable conductor 7 is connected to the spring 6. The fixed conductor 8 is attached to the lower part of the insulating base 1 as shown in FIGS. 3 and 7 while turning it upside down to prevent it from coming off due to the elasticity of the conductor.

For this installation, screws 12.
Then, the holding plate 11 is screwed onto the insulating base 1 as shown in FIG.

That is, the sliding body 5 is first inserted into the recess 1a of the insulating base 1 as shown in FIGS. 3 and 7, and the knob 4 is inserted through the hole 3.
protrude to the outside.

As shown in FIGS. 1 and 2, the fixed conductor 8 is fitted into the embedded fixing groove 9 of the insulating base 1 against the elasticity of the spring 6, and attached to the bottom surface of the insulating base 1 with a locking piece or a not shown. The slide switch according to the present invention is completed by attaching it using the set screw 12 or the like.

Next, the operation of this slide switch will be explained.

First, as shown in FIG. 3, by moving the movable electrical conductor 7 to the right via the knob 4, conduction can be established across the plurality of fixed conductors 8, 8 through the movable electrical conductor 7.

Next, as shown in FIG. 5, if the knob 4 is moved to the center after passing through the state shown in FIG. When the knob 4 is further moved to the left, one of the movable conductors 7 comes into contact with the protrusion Ila of the holding plate 11, so that all the fixed conductors 8,
If the continuity between the two is broken, the switch can be turned off.

The shape of the fixed conductor 8 is not limited to the above-mentioned round pipe shape, but as shown in FIG. Alternatively, as shown in FIG. 9, bus bars may be fixed in parallel in the vertical direction.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

As the fixed conductor of a slide switch, a plurality of strip-shaped narrow conductive plates called busbars are arranged vertically in parallel, or conductive pipes or conductive rods are arranged in parallel, so that a knob can be inserted into the space between these fixed conductors. A part of the movable educational conductor that is operated can elastically snap down to short-circuit the fixed conductors on both sides and turn on the switch.

Then, a part of the movable curved conductor operated by the above-mentioned knob elastically snaps into the space between the fixed conductors, giving a click action or snap action to the knob operation as a slide switch, which was previously unnecessary. The first effect is that crisp knob operation is possible without using the snap action imparting member, and controllability as a switch is improved.

In addition, by operating the knob, the movable conductor can be removed from the space above to turn off the switch, or by dropping a part of the movable conductor into the space between the other fixed conductors, single-pole, double-throw, or double-pole The second effect is that it has a wide range of applications because it functions as a double-throw changeover switch.

Furthermore, the conductive pipe, conductive rod, or conductive plate used as a fixed conductor can be integrally molded into a narrow conductive plate, that is, a bus bar, so the fixed conductor can be directly connected to other electrical components or circuit patterns via the bus bar, etc. Since it can be connected and does not require caulking or lead wires, it saves resources, dramatically improves the ease of assembly as an electrical product, and minimizes the electrical resistance and contact resistance between the circuits used. The third effect is that unnecessary heat generation and fire accidents caused by this heat generation can be prevented.

According to the second aspect, in addition to the above-mentioned effects, the movable conductor 7 is made of a conductive ball such as a steel ball, so that the knob can move smoothly and the switch can be operated smoothly.

In claim 3, since the fixed conductor 8 is properly housed in the groove 9 by the pressing plate II, the switch contact part can be hermetically protected, and the parallel positions of the plurality of fixed conductors 8 are firmly fixed, making it possible to use the switch for a long period of time. As a result, the stability of operation is further guaranteed.
