Abstract
The utility model discloses a switch of a drawing structure, comprising a hard conducting rod, a spherical contact body, a slide pipe and a conductive sleeve. The hard conducting rod, the spherical contact body and the conductive sleeve are conductors, and the slide pipe is an insulator. The spherical contact body is fixedly arranged on the hard conducting rod; the inner wall of the slide pipe is provided with a groove with a shape and a dimension coupled to the shape and dimension of the conductive sleeve, and the conductive sleeve is embedded in the groove; the length of the conductive sleeve is less than the length of the slide pipe; the diameter of the spherical contact body is not less than the internal diameter of the conductive sleeve; the external diameter of the hard conducting rod is less than the internal diameter of the conductive sleeve; and the spherical contact body is disposed in the slide pipe. According to the switch of a drawing structure provided in the utility model, the structure is simple, usage is convenient, and an open or break state can be maintained in a certain travel scope.
Description
Technical field
The utility model relates to a kind of mechanical circuit switch, relates 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 exploitation of switch application product.Such as the desk lamp bulb position is fixing etc.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of switch of drawing structure, and it can guarantee conducting state or the off-state of switch in certain stroke range.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model 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 insulator; Spherical contact is fixed on the hard contact rod, is provided with the groove suitable with conductive sleeve shape, size at the inwall of slip pipe, 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 conductive sleeve is connected with the hard contact rod with after the both positive and negative polarity of power supply is connected, by 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 external diameter of hard contact rod less than the internal diameter of conductive sleeve; Because conductive sleeve has certain length, thereby this switch can guarantee to keep conducting state in certain stroke.
As a kind of project organization, the number of described 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 forcing spherical contact in slip pipe, to move along a direction, just can intermittent realization conducting.
Preferably, described slip pipe is elastic material, so just can be so that spherical contact can the relevant position of effective location in slip pipe.
Beneficial effect: the switch of the drawing structure that the utility model provides, simple in structure, easy to use, it can stay open or off state in certain stroke range.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
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 elastic insulator; Spherical contact 2 is fixed on the hard contact rod 1, is provided with the groove suitable with conductive sleeve 3 shapes, size at the inwall of slip pipe 4, 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 all conductive sleeve 3 length sums less than the length of slip pipe 4, and there is the gap in conductive sleeve 3 spacings.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
