Induction device

Abstract

The invention discloses an induction device comprising a carrier seat, a first terminal unit and a second terminal unit inserted-arranged on the carrier seat respectively and separating from each other, two shared terminal units inserted-arranged on the carrier seat respectively and between said terminal units, a ball bearing rolling-arranged on the shared terminal units and limited by the first terminal unit and the second terminal unit, and a lid covering the assemblies. When the ball bearing is positioned on the shared terminal units and contactless with first and second terminal units, theinduction device is in a non-turned-on state, when the induction device is inclined so that the ball bearing is rolled towards the first terminal unit or the second terminal unit and simultaneously contacted with the first terminal unit and the shared terminal units, or simultaneously contacted with the second terminal unit and the shared terminal units, the induction device is in a turned-on state, in this way, the invention has characteristics of good turning-on effect and ensuring using quality.

Description

technical field [0001] The invention relates to a switch, in particular to an induction device for electronic products. Background technique [0002] refer to figure 1 , 2 , an existing ball switch 100 has an outer cover 101, a ball 102, four terminals 103 and a plug 104. [0003] When assembling, the ball 102 is put into the outer cover 101, and the block 104 is used to block the opening of the outer cover 101 to block the ball 102, and then the aforementioned terminal 103 is connected by a jig (not shown). Insert the four through holes 1041 of the block 104 until each tapered portion 1031 protrudes into the outer cover 101 to complete the assembly. [0004] Although the ball switch 100 can achieve conduction by the ball 102 contacting the aforementioned taper portion 1031, but since the aforementioned terminal 103 is in a suspended state when inserted into the outer cover 101, the precision of the jig operation must be very high. , so that the aforesaid taper 1031 can ...

[0004] Although the ball switch 100 can achieve conduction by the ball 102 contacting the aforementioned taper portion 1031, since the aforementioned terminal 103 is in a suspended state when inserted into the outer cover 101, the precision of the jig operation must be very high. , so that the aforementioned taper 1031 can be flushed to generate the switching action, as long as there is a slight difference in position, it will lose its function. In addition, the aforementioned terminal 103 can only be positioned by inserting into the aforementioned through hole 1041, which is not stable enough and is easily caused by external force factors. Shaking further affects the sensing sensitivity of the ball switch 100

[0005] In addition to the ball switch 100 can be used as figure 2 The shown vertical installation on a circuit board 105 is used for the use mode of the normally open state, and it can also be used as image 3 As shown, first bend the aforementioned terminal 103 and then install it on the circuit substrate 105, so that there is an angle θ between the outer cover 101 and the circuit substrate 105 for the use mode of the normally closed state, because the outer cover 101 is easily suspended Because external factors change the included angle θ, the ball switch 100 loses its function and relatively affects the quality of use.
