Abstract
The invention discloses a switch with a drawing structure. The switch comprises a hard conductive rod, a spherical contact body, a sliding pipe and a conductive sleeve, wherein the hard conductive rod, the spherical contact body and the conductive sleeve are conductors; the sliding pipe is an insulator; the spherical contact body is fixed on the hard conductive rod; a groove of which the shape and size are matched with those of the conductive sleeve is formed on the inner wall of the sliding pipe; the conductive sleeve is embedded into the groove; the length of the conductive sleeve is smaller than that of the sliding pipe; the diameter of the spherical contact body is greater than or equal to the inner diameter of the conductive sleeve; the outer diameter of the hard conductive rod is smaller than the inner diameter of the conductive sleeve; and the spherical contact body is arranged in the sliding pipe. The switch with the drawing structure provided by the invention is simple in structure and convenient to use and can be turned on or turned off in a certain travel range.
Description
Technical field
The present invention relates to a kind of mechanical type contactor, relate in particular to a kind of switch of drawing structure.
Background technology
Switch is the components and parts of control circuit conducting or disconnection, and mechanical switch commonly used is push-button switch or knob switch, and the contact position of switch is fixed, and has limited the switch application Products Development.Such as desk lamp bulb position is fixing etc.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of switch of drawing structure, and it can guarantee the conducting state or the off-state of switch in certain travel range.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of switch of drawing structure comprises hard contact rod, spherical contact, slip pipe and conductive sleeve, and wherein hard contact rod, spherical contact and conductive sleeve are conductor, and slip pipe is an insulator; Spherical contact is fixed on the hard contact rod, and the inwall of slip pipe is provided with and conductive sleeve shape, the suitable groove of size, and conductive sleeve is embedded in the groove; The length of conductive sleeve is less than the length of slip pipe, and the diameter of spherical contact is more than or equal to the internal diameter of conductive sleeve, and the external diameter of hard contact rod is less than the internal diameter of conductive sleeve; Spherical contact places in the slip pipe.
The switch of said structure; During use with conductive sleeve and hard contact rod respectively with after the both positive and negative polarity of power supply is connected, through regulating the position of spherical contact in slip pipe, can realize switch control; When spherical contact contacts with conductive sleeve; Circuit turn-on, when spherical contact contacts with slip pipe, not conducting of circuit; In order to guarantee that spherical contact contacts with the effective of conductive sleeve, require the diameter of spherical contact to equal or be slightly larger than the internal diameter of conductive sleeve; In order to prevent contacting of hard contact rod and conductive sleeve, require the internal diameter of the external diameter of hard contact rod less than conductive sleeve; Because conductive sleeve has certain length, thereby this switch can guarantee in certain stroke, to keep conducting state.
As a kind of project organization, the number of said slip pipe is one, and the number of conductive sleeve is more than one, and all conductive sleeve length sums are less than the length of slip pipe, and has the gap between conductive sleeve; Like this, when force spherical contact in slip pipe along a direction when moving, just can intermittent realization conducting.
Preferably, said slip pipe is an elastic material, so just can be so that spherical contact can effectively be positioned at the relevant position in the slip pipe.
Beneficial effect: the switch of drawing structure provided by the invention, simple in structure, easy to use, it can stay open or off state in certain travel range.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Be illustrated in figure 1 as a kind of switch of drawing structure, comprise hard contact rod 1, spherical contact 2, a slip pipe 4 and a conductive sleeve 3, wherein hard contact rod 1, spherical contact 2 and conductive sleeve 3 are conductor, and slip pipe 4 is an elastic insulator; Spherical contact 2 is fixed on the hard contact rod 1, and the inwall of slip pipe 4 is provided with and conductive sleeve 3 shapes, the suitable groove of size, and conductive sleeve 3 is embedded in the groove; The length of conductive sleeve 3 is less than the length of slip pipe 4, and the diameter of spherical contact 2 is more than or equal to the internal diameter of conductive sleeve 3, and the external diameter of hard contact rod 1 is less than the internal diameter of conductive sleeve 3; Spherical contact 2 places in the slip pipe 4.
Said structure is a basic structure, and the number that can also design slip pipe 4 is one, and the number of conductive sleeve 3 is two or more, but requires the length of all conductive sleeve 3 length sums less than slip pipe 4, and there is the gap in conductive sleeve 3 spacings.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
