Problems solved by technology

[0004] Referring to Fig. 1, in addition, for Taiwan Patent Publication No. 537484 "Ball Switch" new patent case, although the second ball 11 of the ball switch 1 has contact characteristics at all angles (360°), and is matched with a semicircular shell 12 The limiting function of the groove 121 of the terminal 13 and the semicircular groove portion 131 of a terminal 13 enables the ball switch 5 to quickly produce high sensitivity as long as it is affected by external forces at any angle such as vertical direction, horizontal direction or tilting. However, in manufacturing, in order to increase the conductive effect of the shell 11, when the metal shell 12 is subjected to electroplating treatment, the semicircular groove 121 is less likely to be electroplated, and cause inconvenience to manufacture

Embodiment 1

[0046] Referring to FIG. 2 and FIG. 3 , the first preferred embodiment of the ball switch of the present invention includes a housing 2 , four terminals 3 , a ball 4 , and an outer cover 5 .

[0047] Referring to Fig. 2, Fig. 3 and Fig. 4, the housing 2 is made of insulating material such as plastic, and has a base wall 21, and a peripheral wall 22 extending outward along the outer circumference of the base wall 21, and the two cooperate to define There is an accommodating space 24 with an opening 23, and the base wall 21 has four perforations 213 extending from an outer surface 211 to an inner surface 212 in an array to communicate with the accommodating space 24, and the center of the inner surface 212 A conical groove portion 214, two engaging protrusions 215 and two engaging recesses 216 located between the through holes 213 are formed on the position, and four oppositely located on the through holes 213 and formed on the outer surface 211 Guide recess 217.

[0048] The o...

Embodiment 2

[0056] Referring to Fig. 8, the second embodiment of the present invention comprises a housing 2, four terminals 3 (referring to Fig. 3), a ball 4, and an outer cover 5, the implementation concept of the second embodiment is the same as that of the first embodiment, The difference is that the grooves 214 , 514 (see FIG. 4 ) of the housing 2 and the outer cover 5 are changed into conical protrusions 218 , 518 .

[0057] In this way, when the ball switch is vertically fixed on an object 100, and is supported by the protrusion 218, the ball 4 usually contacts with the two terminals 3 no matter which angle it is inclined to. The ball switch is held in the ON state.

[0058] Referring to FIG. 9 , next, similar to the first embodiment, when the ball switch is affected by an external force and vibrates up and down, at this time, the ball 4 vibrating with the object 100 is subjected to a momentary jump, and will temporarily hang in the center of the terminal 3 , not in contact with a...

Embodiment 3

[0062] Referring to FIG. 10 , FIG. 11 and FIG. 12 , the third preferred embodiment of the present invention includes a housing 2 , four terminals 3 , a ball 4 , and an outer cover 5 .

[0063] 11 and 12, the housing 2 is made of insulating material such as plastic, and has a base wall 21, and a peripheral wall 22 extending outward along the outer circumference of the base wall 21. The two cooperate to define a An accommodating space 24 with an opening 23, the base wall 21 has several perforations 213 arranged in an array extending from an outer surface 211 toward an inner surface 212 to communicate with the accommodating space 24, and the central position of the inner surface 212 is formed There is a conical groove portion 214 .

[0064] Each terminal 3 is made of metal material, and extends from the outside to the inside from the through hole 213 into the accommodation space 24 of the housing 2, so that the terminals 3 are arranged in an array around the groove portion 214. ...

Abstract

A ball switch is composed of a casing consisting of a base plate with an array of several through holes and a central arc recess and a peripheral wall to define an internal space with top opening, several terminals passing through said through holes on base plate, at least one ball in said internal space and an external cover for locating said terminals and closing said top opening.

Description

technical field [0001] The invention relates to a switch, in particular to a ball switch. Background technique [0002] In order to solve the general electrical appliances (such as floor lamps, table lamps, vertical electric fans, heaters, electric heaters, mosquito lamps and other movable electrical appliances) toppled due to vibration, which may easily lead to dangers such as wires going off fire or fire, the inventors Many ball switches have been created before, such as: Taiwan Patent Publication No. 468865 "Ball Vibration Switch (3)", No. 476445 "Angle Switch (2)", and No. 537484 "Ball Switch" ... and other new patents case. [0003] In each of the above-mentioned patents, the action principle of the ball switch is to make the ball built in the hollow shell achieve the expected on / off action and use purpose by vibration or angle inclination, although the above-mentioned patent All can achieve the expected purpose of use, but, in order to ensure the actuation effect of ...
