Description
Technical field
The present invention relates to a kind of ball switch, particularly relate to a kind of ball switch and manufacture method thereof of simple and convenient assembly.
Background technology
As shown in Figure 1 and Figure 2, the inventor had before designed and had got permission the ball vibroswitch 10 of No. 155965 patent in Taiwan, comprised an insulating sleeve 11, one and was installed in the ball 12 in this insulating sleeve 11, four metal terminals 13 and insulation chocks 14.
This sleeve 11 is square type column plastic cement cell bodies, has an opening 111, two interlocking protuberances 112 that reach contiguous this opening 111 and be convexly equipped with from the inner ring surface correspondence.
Each terminal 13 has respectively and is a rightabout built-in tapering 131 and an external tapering 132.
This insulation chock 14 has four through holes 141 that pass for aforementioned terminal 13, and is arranged on outer ring surface and uses for setting two interlocking recesses 142 that combine mutually with aforementioned interlocking protuberance 112.In addition, the periphery of aforementioned terminal 13 directly is slightly larger than the aperture of aforementioned through-hole 141, and then can produce the tight fit effect.
During assembling, be earlier this ball 12 to be dropped in this sleeve 11, then, aforementioned terminal 13 is inserted aforementioned through-hole 141 respectively, the chock 14 that then will insulate is sealed in the opening 111 of this sleeve 11, so that being limited in by this sleeve 11, this ball 12 cooperated in the bearing space 15 that forms with this insulation chock 14, this ball 12 can contact or not contact with the built-in tapering 131 of aforementioned terminal 13 simultaneously, at last, this opening 111 recharge epoxy resin 114 to finish assembling in the remaining space 113.
It is (not shown that this ball vibroswitch 10 can be used for vertical electric equipment products, electric heater for example), deserve electric equipment products when being in normal operating condition, can contact aforementioned built-in taperings 131 so that the power supply of these electric equipment products is held open by this ball 12, when these electric equipment products run into external force and topple over, can roll by this ball 12 and not contact aforementioned built-in tapering 131, and then improve safe in utilization so that the power supply of these electric equipment products is closed automatically.
Though this ball vibroswitch 10 has above-mentioned function of use, but still there is following shortcoming:
One, in order to improve using character, must make this ball 12 all identical with the butt angle in each built-in tapering 131, just must make each built-in tapering 131 contour concordant, but because aforementioned terminal 13 is the individual member design, aforementioned terminal 13 to be inserted aforementioned through-hole 141 respectively and make each built-in tapering 131 concordant, and then identical with the butt angle of this ball 12, in fact there is the shortcoming that number of assembling steps is more complicated, assembling is more time-consuming.
Two, as shown in Figure 3, when aforementioned built-in tapering 131 not concordant and when having difference in height I, the butt angle in this ball 12 and aforementioned built-in tapering 131 is with inequality, so, can make this ball 12 be subjected to side external force and then roll from the action in aforementioned built-in tapering 131 inconsistently, relatively have the relatively poor shortcoming of action stability.
Summary of the invention
The objective of the invention is in the ball switch and the manufacture method thereof that a kind of simple and convenient assembly is provided, saves time, action stability is good.
Ball switch of the present invention comprises one first insulation crust, second insulation crust, insulation centerbody, two sheet metals and a ball, it is characterized in that:
