Abstract

A ball switch comprises a sleeve, base bodies and balls. A big ball and a small ball are arranged in a cavity of the sleeve, the base bodies are installed at the positions of openings at two ends of the sleeve, and one end of the sleeve is gradually contracted to a small mouth and forms a conical surface angle. An insulation base body is arranged in the small mouth of the sleeve, a conductive base body is arranged in the big mouth of the sleeve, a first terminal penetrates through the center of the insulation base body, and a second terminal penetrates through the center of the conductive base body. As long as an angle formed by the ball switch and the horizontal plane is less than 40 degrees, the ball switch is in an open circuit state, thereby being capable of achieving effects of safety and electricity saving.

Description

Ball switch

Technical field

The utility model relates to a kind of switch, especially relates to a kind of ball-type vibration switch.

Background technology

Vibroswitch is used quite general in electronic product, ball-type vibration switch particularly, and its adopts cartridge type housing, built-in ball; The housing two ends are provided with terminal, and when receiving when vibrating, ball rolls in endoporus; When ball contact two-terminal, this ball switch conducting, this switch manufacturing process is simple; Volume is little, and cost is low, is widely used.But when being applied to like products such as electronic pens; Need when product tilts or keeps flat to make power supply be automatic closed condition by the rolling of ball; Reach the purpose of economize on electricity; But its dump angle will be less than horizontal plane 10 degree and just can close, so with regard to its fail safe and effect property, still have some deficits, also need improve.

Summary of the invention

The purpose of the utility model is to existing deficiency, provides a kind of when the angle of inclination is spent less than 40, and power supply is a kind of ball switch of closed condition automatically.

The utility model solves the technical scheme that its technical problem adopted: a kind of ball switch, comprise sleeve pipe, base body, ball, and said sleeve pipe cavity is built-in with big ball and little ball; Base body is equipped with at sleeve pipe both ends open place, and said sleeve pipe one end is apered to a path mouth, and forms a conical surface angle; Sleeve pipe path mouth device insulating base body; Insulating base body center is penetrated with the first terminal, the big footpath of sleeve pipe mouth device conductive base body, and conductive base body center is penetrated with second terminal.

The said end face that is positioned at the first terminal of insulating base body is a circular arc.

Said sleeve pipe conical surface angle is 45 degree.

Said sleeve pipe is that metal material is processed.

Said little ball external diameter is 1/2 of a big ball external diameter.

The angle that the utility model utilizes the sleeve pipe conical surface to tilt changes the position of ball, makes power turn-on or disconnection, and when little ball is in when contacting with the end face of the first terminal and the sleeve pipe conical surface, power supply is conducting state.Little ball top is pressed with big ball, has strengthened the stability of contact point, has avoided the instability of signal transmission in the turn on process.And when the sleeve pipe angle of inclination changed, when just the ball switch angle of inclination was spent less than horizontal plane 40, ball rolled and to have broken away from and the contacting of the first terminal, and made power supply be off-state, reached the purpose of safety electricity-saving.

Fig. 1 is the structural representation of the utility model.

The structural representation of open-circuit condition when Fig. 2 is the utility model inclination.

Below in conjunction with accompanying drawing and execution mode the utility model is remake and to further describe.

Embodiment

Like Fig. 1, shown in 2; A kind of ball switch comprises sleeve pipe, base body, ball, and said sleeve pipe 1 cavity is built-in with ball; Ball comprises big ball 301 and little ball 302; Said little ball 302 external diameters are 1/2 of big ball 301 external diameters, and ball is that metal material is processed, and large and small ball skin is all silver coated.Base body is equipped with at sleeve pipe 1 both ends open place, and base body comprises insulating base body 202 and conductive base body 201, and insulating base body 202 can be made of plastic, and conductive base body 201 adopts metal stamping to form.Said sleeve pipe 1 is processed for metal material, and sleeve pipe 1 one ends are apered to a path mouth 102, and forms a conical surface 101 angles, and the said sleeve pipe conical surface 101 angle design of present embodiment are 45 degree.Sleeve pipe path mouth 102 tight plug insulating base bodies 202, insulating base body 202 centers are penetrated with the first terminal 4, and the end face 401 that is positioned at the first terminal of insulating base body is circular arc.The big footpath of sleeve pipe mouth 103 tight plug conductive base bodies 201, said conductive base body 201 centers are penetrated with second terminal 5.

When ball switch under normal operating condition, just ball switch in vertical state or ball switch angle of inclination when spending greater than 45, little ball 302 is in the end face 401 of the first terminal and contacts with the sleeve pipe conical surface 101, this moment, ball switch was a conducting state.Little ball 302 tops also are pressed with big ball 301; Strengthened the stability of contact-making surface; When the ball switch angle of inclination is spent less than 40, be benchmark with the horizontal plane, big ball 301 and little ball 302 have all broken away from and the contacting of the first terminal 4; Make ball switch be in off-state, power supply then is in open-circuit condition.

Therefore, according to said structure, ball switch is so long as constitute when spending greater than 45 with horizontal plane, and ball switch is in conducting state can normally be used.In the time of on being used in electronic pen, as long as electronic pen does not use and lies on the plane, ball switch promptly is open-circuit condition, then can reach less electricity consumption.The utility model more is applicable on the electronic product of miniaturization.
