Background

The touch key has the working principle that a capacitor exists between any two conductive objects, two copper-exposed areas between the PCBs are two polar plate capacitors of the capacitor, when a finger of a human body contacts the plastic shell, the capacitance value can be changed due to the conductivity of the human body, and the touch key chip immediately detects that the capacitance value is increased and then generates an output on-off signal. The assembly of the touch key PCB and the plastic surface shell needs to be in a flat state, and the assembly and fixing mode between the touch key PCB and the plastic surface shell is extremely important.

At present, the current assembly method of the touch key PCB board and the plastic surface shell is as follows: one side of the PCB is firstly clamped in the plastic surface shell 2PCS buckle; then the other side of the PCB is pressed into the plastic surface shell 1PCS buckling position by two hands. The touch key PCB is pressed by hand to be assembled to the buckling position of the plastic face shell, which is also a fixing mode of the touch key PCB and the plastic face shell commonly used in the prior art. However, the assembly method still has some disadvantages, because the thickness of the touch key PCB is 1.2mm, the height of the corresponding buckling position on the plastic surface shell is also short, and the buckling position loses its plastic elasticity due to the limitation of height, so that the plastic buckling position is very easy to break or damage when the touch key PCB is pressed hard to buckle into the plastic buckling position, and finally the assembly of the touch key PCB is affected, and the efficiency is greatly reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the utility model discloses a fixed knot constructs including plastic face shell 3 and plastic face shell 3 complex be used for fixing PCB board 2 gland 1 on plastic face shell 3, be equipped with two in PCB board 2 installation position both sides and detain

position

31, 1 both ends of gland are equipped with and detain position 31 complex screens 11, PCB board 2 is placed behind PCB board installation position, gland 3 sets up in PCB board 2 top to screens 11 through both ends are fixed with detaining position 31 joint. For the convenience of installation, the periphery of the PCB installation position of the embodiment is provided with a limiting bone 32 for limiting the PCB 2.

As shown in fig. 4 and 5, the gland 2 of this embodiment is arranged in a central symmetry manner, the middle of the upper surface of the gland 2 is provided with a handle 12 for easy operation, and two ends of the gland 2 are respectively provided with two centrally symmetric detents 11. The blocking part 11 includes a blocking surface 111 arranged along the width direction of the gland 1, one side of the blocking surface 111 is provided with a guide inclined surface 14 arranged perpendicular to the length direction of the gland 2, and the blocking surface 111 is arranged at the top end of the guide inclined surface 14.
