Abstract

A surface-insulated touch key spring structure comprises a touch key spring, wherein the touch key spring is arranged on a PCB (printed Circuit Board), and the surface of the touch key spring is coated with a layer of insulating paint; a touch pad plate is arranged at the top of the touch key spring, and a touch glass panel is arranged on the upper surface of the touch pad plate; according to the surface-insulated touch key spring structure, the insulating paint is plated on the surface of the spring, so that the touch key cannot be normally used due to signal interference generated by the spring when in use.

Description

Surface-insulated touch button spring structure

Technical Field

The utility model belongs to the technical field of the PCB leaf spring, concretely relates to surface insulation's touch button spring structure.

Background

The spring is assembled on the PCB, which is a common process in the electronic manufacturing industry, the spring is assembled by the traditional household appliance touch control PCB, and the spring is contacted with the spring of the traditional touch control key by adopting a layer of insulating film for ensuring that the spring does not generate signal interference, but the method has great defects, the installation is more complicated, the manufacturing cost is relatively high, meanwhile, the touch control key is unstable in use, and the unstable condition of sensitivity can often occur.

Therefore, it is necessary to design a surface-insulated touch key spring structure to solve the above technical problems.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model aims to provide a surface insulation's touch button spring structure.

In order to achieve the above objects and other related objects, the present invention provides a technical solution: a surface-insulated touch key spring structure comprises a touch key spring, wherein the touch key spring is arranged on a PCB (printed Circuit Board), and the surface of the touch key spring is coated with a layer of insulating paint; a touch pad plate is installed at the top of the touch key spring, and a touch panel is installed on the upper surface of the touch pad plate.

Preferably, the bottom of the touch key spring is fixed with the PCB through solder paste.

Preferably, pins are arranged at the bottom of the touch key spring, mounting holes are formed in the surface of the PCB, and the pins at the bottom of the touch key spring are inserted into the mounting holes of the PCB.

Preferably, the surface of the touch button spring adopts a mode of electroplating insulating paint.

Because of the application of the technical scheme, compared with the prior art, the utility model the advantage that has as follows:

according to the surface-insulated touch key spring structure, the insulating paint is plated on the surface of the spring, so that the touch key cannot be normally used due to signal interference generated by the spring when in use; compared with the traditional scheme that a layer of insulating film is added between the spring and the touch panel, the scheme is simpler in structure and lower in cost, meanwhile, the touch spring can be guaranteed to be more stable in use, and the condition that the key sensitivity is unstable can not occur.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the product of the present invention is usually placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, a surface-insulated touch key spring 2 structure includes a touch key spring 2, the touch key spring 2 is mounted on a PCB board 1, and a layer of insulating paint is coated on the surface of the touch key spring 2; a touch pad plate 3 is arranged at the top of the touch key spring 2, and a touch panel 4 is arranged on the upper surface of the touch pad plate 3; according to the structure of the touch key spring 2 with the insulated surface, the insulated paint is plated on the surface of the spring, so that the touch key cannot be normally used due to signal interference generated by the spring when in use; compared with the traditional scheme that a layer of insulating film is added between the spring and the touch panel, the scheme is simpler in structure and lower in cost, and meanwhile, the touch spring can be more stable in use, and the condition of key failure cannot occur.

The preferred embodiment is as follows:

the bottom of the touch button spring 2 is fixed with the PCB 1 through solder paste.

The bottom of the touch key spring 2 is provided with a pin 5, the surface of the PCB board 1 is provided with a mounting hole, and the pin 5 at the bottom of the touch key spring 2 is inserted into the mounting hole of the PCB board 1.

The springs are of two types with and without pins 5, and the two different types of springs are different from the mounting structure of the PCB, one through solder paste and the other through pins 5.

The surface of the touch button spring 2 adopts a mode of electroplating insulating paint.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
