Induction device

Abstract

An induction device includes a seat, a first terminal unit and a second terminal unit respectively installed in the seat and spaced apart from each other, a ball, and an outer cover for closing the seat. The first terminal unit includes a first connection block, and two first terminals extending from the first connection block, each of the first terminals has a main body, and one extends from the main body and passes through the support. The terminal portion outside the seat, and an extension portion extending from an inner side surface of the main body portion and provided with a supporting surface. The second terminal unit includes a second connecting block and two second terminals extending from the second connecting block, each second terminal has a main body and a terminal extending from the main body. When the ball is on the bearing surface and does not touch the second terminal unit, the sensing device is in a non-conductive state; when the ball is on the bearing surface and contacts the second terminal unit, the sensing device is in a state of conduction state.

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 a sleeve 101, a ball 102, four terminals 103 and a plug 104. [0003] When assembling, the ball 102 is put into the sleeve 101, and the block 104 is used to block the opening of the sleeve 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 sleeve 101 to complete the assembly. [0004] Although the ball switch 100 can achieve conduction through the ball 102 contacting the aforesaid taper portion 1031, since the aforesaid terminal 103 is in a suspended state when inserted into the sleeve 101, the precision of the fixture operation must be very high. Only by making the aforesaid taper 1031 flush to generate switching ac...

Problems solved by technology

[0004] Although the ball switch 100 can achieve conduction through the ball 102 contacting the aforesaid taper portion 1031, since the aforesaid terminal 103 is in a suspended state when inserted into the sleeve 101, the precision of the fixture operation must be very high. Only by making the aforesaid taper 1031 flush to generate switching action, as long as there is a slight difference in position, it will lose its function. In addition, the aforesaid terminal 103 is only positioned by inserting the aforesaid through hole 1041, which is not stable enough, and it is very easy to shake due to external factors. affect the inductive 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 sleeve 101 and the circuit substrate 105 for the use mode of the normally closed state, because the sleeve 101 is easy to hang in the air Because external factors change the included angle θ, the ball switch 100 loses its function
