Ball bearing switch and its making method

Abstract

The invention provides a ball switch and a method for manufacturing the same, comprising a first insulation outer shell, a second insulation outer shell, an insulation central arrangement body, two metal sheets and a ball, wherein the insulation central arrangement body is provided with a first connection surface and a second connection surface which are opposite in direction; the first connection surface is used to be connected with the first insulation outer shell, and the second connection surface is used to be connected with the second insulation outer shell; the two metal sheets are arranged respectively between the first insulation outer shell and the insulation central arrangement body and between the second insulation outer shell and the insulation central arrangement body; the combination of the first insulation outer shell, the second insulation outer shell, the insulation central arrangement body and the metal sheets can limit a receiving space for receiving the ball, and the ball can move between a conduction connection position and a non-conduction connection position, thereby the ball switch has the advantages of relatively simple assembly and good action stability.

Description

technical field [0001] The invention relates to a ball switch, in particular to a ball switch with easy assembly and a manufacturing method thereof. Background technique [0002] Such as figure 1 , figure 2 As shown, the inventor previously designed and approved the ball vibration switch 10 of Taiwan No. 155965 patent, which includes an insulating sleeve 11, a ball 12 installed in the insulating sleeve 11, four metal terminals 13 and an insulating plug Block 14. [0003] The sleeve 11 is a rectangular columnar plastic tank with an opening 111 and two embedding protrusions 112 adjacent to the opening 111 and protruding from the inner ring surface. [0004] Each branch terminal 13 respectively has an inner taper portion 131 and an outer taper portion 132 in opposite directions. [0005] The insulating block 14 has four through holes 141 through which the terminals 13 pass, and two embedding recesses 142 provided on the outer ring surface for interfitting and combining wit...

Problems solved by technology

[0009] 1. In order to improve the quality of use, the ball 12 must have the same contact angle with each built-in taper 131, that is, each built-in taper 131 must be equal in height, but because the aforementioned terminal 13 is designed as an independent component, To respectively insert the aforementioned terminals 13 into the aforementioned through holes 141 and make each built-in tapered portion 131 flush so as to have the same abutment angle with the ball 12 actually has the disadvantages of complicated and time-consuming assembly steps.

[0010] Two, such as image 3 As shown, when the aforementioned built-in tapered portion 131 is uneven and there is a height difference I, the abutment angles of the ball 12 and the aforementioned built-in tapered portion 131 will be different, so that the ball 12 will be subject to side external force and roll. The action of the built-in taper 131 is not consistent with the aforementioned, and relatively has the disadvantage of poor action stability
