CN202514164U - A pressure-resistant circuit board - Google Patents

Abstract

The utility model relates to a pressure-resistant circuit board which comprises a board body, a circuit element and an electric contact, wherein the circuit element is mounted on the board body, and the electric contact is electrically connected with the circuit element. The circuit element and the electric contact are distributed on two sides of the board body, and rubber matrixes are connected between the circuit element and the board body and between the electric contact and the board body respectively. As the rubber matrixes are added on the circuit element and the electric contact, vibration generated by pressing is reduced, the pressure resistance of the circuit board is enhanced, and the service life of the circuit element is prolonged.

Description

A kind of withstand voltage wiring board

Technical field

The utility model relates to board structure of circuit, is specifically related to withstand voltage wiring board.

Background technology

Electronic product Development Trend such as present portable terminal are ultralights, ultra-thin, extra small, thereby the lightening of structural member in the electronic product and pcb board is Development Trend.With the portable terminal product is example, after the portable terminal product is lightening, because local strength's problem of positions such as button influences the button feel.And since the portable terminal product kick the beam, thin excessively, the pcb board that causes being positioned at the button equipotential side of depositing is damaged under the situation of repeatedly pushing easily.Therefore, be badly in need of the strong pcb board of a kind of anti-pressure ability.

The utility model content

In order to overcome the deficiency of prior art, the purpose of the utility model is to propose a kind of withstand voltage and withstand voltage wiring board that compressive resistance is strong.

In order to achieve the above object, the technical scheme that the utility model adopted is following:

A kind of withstand voltage wiring board, it comprises plate body, is installed in the circuit element on the plate body, and the electric contact that electrically connects with circuit element.Circuit element, electric contact distribute and are positioned at the both sides of plate body, are connected with colloid between circuit element and the plate body, also are connected with colloid between electric contact and the plate body.

As preferred construction, plate body is flexible plate body.

The utlity model has following beneficial effect:

Owing on circuit element and electric contact, increased colloid, reduce the vibration problem that produces because of pushing, thereby strengthened the anti-pressure ability of wiring board, prolonged the useful life of circuit element.

Description of drawings

Fig. 1 is the structural representation of the withstand voltage wiring board of the utility model preferred embodiment.

Embodiment

Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.

Like Fig. 1, a kind of withstand voltage wiring board, it comprisesplate body 1, is installed in thecircuit element 2 on theplate body 1, and the electric contact 4 that electrically connects withcircuit element 2.

Circuit element 2, electric contact 4 distribute and are positioned at the both sides ofplate body 1, are connected withcolloid 3 betweencircuit element 2 and theplate body 1, also are connected withcolloid 6 between electric contact 4 and theplate body 1.

Theplate body 1 of present embodiment is flexible plate body.

During use, be installed in the withstand voltage wiring board of present embodiment in one housing earlier, thebutton 5 on the housing is corresponding with electric contact 4.Duringpressing keys 5, the bottom ofbutton 5 can be connected with electric contact 4, realizes the function that button is corresponding.Push the pressure that produces in the process and absorbed bycolloid 3 andcolloid 6 or alleviate, improved the compressive property of wiring board.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.

Claims (2)

1. withstand voltage wiring board; Comprise plate body, be installed in the circuit element on the plate body, and the electric contact that electrically connects with circuit element; Circuit element, electric contact distribute and are positioned at the both sides of plate body; It is characterized in that, be connected with colloid between circuit element and the plate body, also be connected with colloid between electric contact and the plate body.

2. withstand voltage wiring board as claimed in claim 1 is characterized in that, plate body is flexible plate body.
