Abstract
The utility model discloses a ball switch, comprising a casing pipe, a base body and a ball, wherein the casing pipe is provided with a unidirectional opening and is cylindrical, a ball is arranged inside an inner cavity of the casing pipe, the base body is arranged at an opening part of the casing pipe, a circular groove is formed in the center on the inner side face of the base body in a manner of sinking inwards, the center of the bottom of the groove is provided with a first terminal penetrating through the base body, a conical surface which inclines and diverges outwards is formed on the peripheral wall above a groove opening, an electric conductor is embedded into the groove, the inner annular conical surface of the electric conductor is level to the conical surface above the groove opening, and a second terminal connected with the electric conductor penetrates out of the exterior of the base body. According to the utility model, as long as an included angle formed between the ball switch and the horizontal plane is smaller than 40 degrees, the ball switch is in an open circuit state, and thus, the effects of safety and electricity saving are achieved.
Description
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, when receiving when vibrating; Ball rolls in endoporus, when ball contact two-terminal, and this ball switch conducting.This switch manufacturing process is simple, and 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 is that unidirectional opening is cylindric; The sleeve pipe cavity is built-in with ball; Base body is equipped with at said ferrule openings place, and said base body medial surface center is to the circular groove that caves in, and the bottom portion of groove center is provided with the first terminal that runs through base body; Groove mouth top perisporium forms the conical surface of outward-dipping flaring; Said groove is embedded in electric conductor, and annular conical surface is equal with the conical surface of groove mouth top in the electric conductor, and second terminal that electric conductor connects passes the base body outside.
Said electric conductor is that sheet metal is stamped to form, and its top is big footpath mouth, and the bottom is the path mouth, tapered ring bodies.
The said electric conductor and second terminal are integral structure.
The said end face that is positioned at the first terminal of bottom portion of groove is a circular arc.
The annular conical surface angle is 45 degree in the said electric conductor.
The conical surface angle of said groove mouth top is 45 degree.
The utility model utilizes the angle that annular conical surface tilts in the electric conductor, changes the position of ball, makes power turn-on or disconnection; When annular conical surface contacted with two electrode terminals in ball gets into electric conductor, power supply was conducting state, and when the electric conductor angle of inclination changes; When just the ball switch angle of inclination is spent less than horizontal plane 40; Ball rolls and to have broken away from and the contacting of two electrode terminals, and makes power supply be off-state, reaches the purpose of safety electricity-saving.

Fig. 4 is the structural representation of the utility model when favouring plane and switch and being off-state.
Below in conjunction with accompanying drawing and execution mode the utility model is further described.
Embodiment
Like Fig. 1,2, shown in 3, a kind of ball switch comprises sleeve pipe 1, base body 3, ball 2; Said sleeve pipe 1 is cylindric for unidirectional opening, and sleeve pipe 1 is made of plastics, and sleeve pipe 1 cavity is built-in with ball 2; Ball 2 is a metal material, and the ball skin is a silver coating, and said sleeve pipe 1 opening part is provided with base body 3; Base body 3 is the insulating material body, and base body 3 is tightly filled in sleeve pipe 1 openend, makes ball 2 be positioned at sleeve pipe 1; The center of base body 3 is to the circular groove 301 that caves in the said sleeve pipe 1, and groove 301 bottom centre are provided with the first terminal 5 that runs through base body 3, and the end face 501 of the first terminal 5 is a circular arc; 301 mouthfuls of tops of groove perisporium forms the conical surface 302 of outward-dipping flaring, and the conical surface angle that the described groove mouth of present embodiment top perisporium forms outward-dipping flaring is designed to 45 degree, and said groove 301 is embedded in electric conductor 4; Said electric conductor 4 is for sheet metal is stamped to form, and its top is big footpath mouth 402, and the bottom is a path mouth 403; Tapered ring bodies, angle design of annular conical surface 401 is 45 degree in it, after electric conductor 4 embeds in the groove 301; Annular conical surface 401 is equal with the conical surface 302 of groove mouth top in it, and second terminal 7 is an integral structure with electric conductor 4, and second terminal 7 passes base body 3 outsides.
Like Fig. 1, shown in 4; When ball switch under normal operating condition; Just ball switch in vertical state or ball switch angle of inclination when spending greater than 45, ball 2 is in the interior annular conical surface 401 of electric conductor and contacts with the first terminal 5, ball switch is a conducting state at this moment.When the ball switch angle of inclination is spent less than 40; With horizontal plane 6 is benchmark; Ball 2 has broken away from the angle of annular conical surface 401 and contacting of the first terminal 5 in the electric conductor, and falls to lying on the recess 8 between the base body conical surface 302 and sleeve pipe 1 sidewall, and at this moment ball 2 can't touch any terminal; 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 can normally use.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, and the utility model more is applicable on the electronic product of miniaturization.
