Abstract
The present invention discloses a point contact switching device of a centrifugal switch, which belongs to a switch using a centrifugal device for a motor. The centrifugal switch body is rotatablely provided with actuating rods; the inner side of the switch body is provided with a first bottom panel and a second bottom panel; each actuating rod is provided with a pin-shaped protrusion; a hook part is formed on the pin-shaped protrusion; the first bottom plane is provided with a via hole for the insertion of the pin-shaped protrusion. The present invention has a function of actuating the first and the second bottom panels at the same; the range for making is wider than that of a bottom panel on the basis of the side face of a front actuating rod as reference; thereby, the thickness of each actuating rod needs to be increased. The bottom plane of the present invention performs the function of the actuating rods; thereby, the actuating rods can be miniaturized, and the cost is reduced. In company with the reduction of the range of each actuating rod, the range of a whole outer shell together with connection points for connecting are miniaturized, which can make the products miniaturized, and the present invention has the effects of reducing cost, etc.
Description
Technical field
The invention relates in the motor switch of using centrifugal device, particularly actuating strut and the miniaturization shell that a pair of bottom panel moves rotatably is set at the centrifugal switch body, and the point that can reduce the centrifugal switch of cost connects switching device.
Background technology
Fig. 1 is the vertical profile structural representation of centrifugal switch in the conventional art, and Fig. 2 is the side-looking structural representation of actuating strut in the conventional art,
Fig. 3 is the planar structure schematic diagram of bottom panel in the conventional art.
As shown in the figure, centrifugal switch in the conventional art rotatably is provided with the actuating strut 11 that a side is inserted spring in the inside of Switch main body 10, be provided with the 1st bottom panel 13 and the 2nd bottom panel 14 in actuating strut 11 inboards, and be formed with protuberance 11a, 11b in the side of actuating strut 11, make the 1st, 2 bottom panels 13,14 move.
Actuating strut is benchmark with the side in the centrifugal switch of conventional art like this, so its bottom panel is made with the amplitude of broad, the thickness of actuating strut also must increase, therefore, along with the volume change of whole casing is big, have problems such as occupying very big space and increase expense.
Summary of the invention
The present invention proposes for the problem that solves in the above-mentioned conventional art, its objective is actuating strut and the miniaturization shell that inboard a pair of bottom panel moves that can be rotatably set in that the centrifugal switch body is provided, and reduce the point contact switching device of a kind of centrifugal switch of cost.
In order to achieve the above object, the invention provides a kind of point contact switching device of centrifugal switch, on the centrifugal switch body, rotatably be provided with actuating strut, and be provided with the 1st bottom panel and the 2nd bottom panel in the actuating strut inboard; Above-mentioned actuating strut is formed with pin type protuberance, is formed with hook portion on the protuberance, and is formed with the through hole that inserts pin type protuberance at the 1st bottom panel.
In the present invention of design like this, the vertical component that plays the effect of actuating strut contact is made into the ellipse cylinder, pars intermedia at the bottom panel of 2 bottom panels and actuating strut adjacency forms through hole, make it that certain intensity be arranged, for making contact synchronous, should regulate the height of cylinder type actuating strut during making by hierarchical structure.
She Ji the present invention like this, the operating principle of its centrifugal switch is with identical in the past, but on the side of its structure to size and cost towards favourable direction design, form in the past is to be that the side makes whole pillar with the actuating strut, and moves the 1st bottom panel and the 2nd bottom panel.Form after the improvement is the mid portion formation through hole at the 1st bottom panel, and the pin type protuberance by actuating strut is connected to the 2nd bottom panel in its hole.And be formed with hook portion at pin type protuberance, carry out the action of the 1st bottom panel or the 2nd bottom panel.
The point contact switching device of centrifugal switch of the present invention forms pin type protuberance on actuating strut, and forms hook portion on pin type protuberance, has the function that the 1st bottom panel and the 2nd bottom panel move simultaneously.And actuating strut was benchmark with the side in the past, so the thickness when making actuating strut is wideer than bottom panel, but the amplitude of bottom panel of the present invention plays the effect of actuating strut, so the actuating strut miniaturization and reduce cost.Along with the amplitude minimizing of actuating strut, also reduced the amplitude of whole casing, along with the contact miniaturization that connects, make the product of making have the effect of miniaturization and expense minimizing.

Embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Fig. 4 is the vertical profile structural representation of centrifugal switch of the present invention, and as shown in the figure, the inside of centrifugal switch body 20 rotatably is provided with the actuating strut 21 that a side is inserted spring 22, and in actuating strut 21 inboards the 1st bottom panel 23 the 2nd bottom panel 24 is set.
Fig. 5 is the side-looking structural representation of actuating strut of the present invention.The part of rising head main body contact effect is used to form pin type protuberance 21a, and is formed with hook portion 21b on pin type protuberance 21a.
Fig. 6 is the planar structure schematic diagram of bottom panel of the present invention, forms the through hole 23a that inserts above-mentioned pin type protuberance 21a at the panel body and realizes.
As mentioned above, the point contact switching device of centrifugal switch, on centrifugal switch body 20, rotatably be provided with actuating strut 21, and be provided with the 1st bottom panel 23 and the 2nd bottom panel 24 in actuating strut 21 inboards, actuating strut 21 is formed with pin type protuberance 21a, and on protuberance 21a, be formed with hook portion 21b, be formed with the through hole 23a that inserts pin type protuberance 21a at the 1st bottom panel 23.
Above-mentioned actuating strut 21 pin type protuberance 21a are formed with the cylinder type of oval section.
The present invention's actuating strut 21 and use of bottom panel 23,24 in the past is the same, but the shape difference.Bottom panel 23,24 connected on contact or cutting off equally, but is not to support the form that the pars intermedia of the 1st bottom panel 23 comes contact in the lateral support mode, thus the form simplification of actuating strut 21, and can make miniaturization to centrifugal switch.
