Description

A kind of new type functional ground structure using conductive sponge

Technical field

The utility model relates to a kind of new type functional ground structures using conductive sponge.

Background technique

The machine that this department develops at present is all by earth lead connecting substrate and automatically controlled metal plate, to reach functional mostly The purpose of ground connection, specifically, needing to draw ground line from substrate, ground line being passed through to reach functional substrate ground connection Screw is fixed on metal plate, however, such structure increases the limitation on substrate cabling and metal plate tectonic sieving.

Currently, the touch screen for having a kind of special machine is to constitute electrode with the gasket (conductive sponge) of elastic force, utilize The ductility of conductive sponge realizes the function of perception human body touch, and specific configuration is as shown in Figure 1, be front comprising: touch screen Plate 1 ', cover board 2 ', conductive sponge 3 ', substrate 4 ', electrode 5 '；Its principle is: promoting conductive sponge when finger touches front panel 1 ' 3 ' bottom surface touches the electrode 5 ' on substrate 4 ', to realize the function of perception human body touch.

Utility model content

The purpose of this utility model is to provide a kind of new type functional ground structures using conductive sponge, by base Plate needs that conductive sponge is arranged at the position of functional grounding, and metal plate is pressed in the other side of conductive sponge, thus using conductive The compressibility of sponge realizes the purpose of functional grounding.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of new type functional ground structure using conductive sponge, characterized in that include:

Substrate；

Conductive sponge, one end connect the position that the substrate needs functional grounding；

It is grounded metal plate, the other end of the conductive sponge is pressed in, the conductive sponge is made to be in compressive state.

The above-mentioned new type functional ground structure using conductive sponge, in which:

The substrate is parallel with ground connection metal plate, and the conductive sponge is located between substrate and ground connection metal plate；

The entire end face connecting substrate of described conductive sponge one end needs the position of functional grounding；

The ground connection metal plate pushes down the entire end face of the conductive sponge other end.

The substrate needs the position of functional grounding to be equipped with ground connection copper foil；

One end of the conductive sponge is connect with the ground connection copper foil.

One end of the conductive sponge and the ground connection copper foil pass through welded connecting.

The conductive sponge is in the form of a column.

The cross section of the conductive sponge is round or regular polygon.

The conductive sponge is in compressive state, when the distance between both ends of the surface are less than it under natural conditions both ends of the surface it Between distance.

Compared with the prior art, the utility model has the following advantages:

1, the even distribution of conductive sponge can protective grounding copper foil, avoid using ground line when due to pull etc. external force Copper foil disrepair phenomenon caused by applying, while there is corrosion resistance, perfect medium when being long term storage；

2, the associated members such as ground line, terminal have been saved, have reached drop into effect；

3, using ground connection copper foil, so that when cabling and layout designs, for functional grounding, it is only necessary to there is one piece of large area The position of copper foil floor file can be realized, and reduce copper foil wiring problem, bring more more options to substrate wires design.

Fig. 3 is the overall structure diagram of the utility model；

Overall structure diagram when Fig. 4 is ground connection metal plate inclination in the embodiments of the present invention.

Specific embodiment

The utility model is done and is further explained by the way that a preferable specific embodiment is described in detail below in conjunction with attached drawing It states.

As shown in figure 3, the utility model proposes a kind of new type functional ground structure using conductive sponge, packet Contain: substrate 2；Conductive sponge 1, one end connect the position that the substrate 2 needs functional grounding；It is grounded metal plate 4, is pressed in described lead The other end of electric sponge 1 makes the conductive sponge 1 be in compressive state.The compressible of conductive sponge is utilized in the utility model Property realize the purpose of functional grounding, also, also a save the associated members such as ground line, terminal, reach drop into effect.

Preferably, the substrate 2 with ground connection metal plate 4 it is parallel, the conductive sponge 1 be located at substrate 2 be grounded metal plate 4 it Between；The entire end face connecting substrate 2 of described 1 one end of conductive sponge needs the position of functional grounding；The ground connection metal plate 4 is pushed down The entire end face of 1 other end of conductive sponge.Since the conductive sponge is in compressive state, as shown in Figure 2,3, The distance between both ends of the surface L1 when the distance between its both ends of the surface L2 is less than it under natural conditions.

In general, the substrate needs the position of functional grounding to be equipped with ground connection copper foil 3；In the present embodiment, in order to ensure even It connects reliably, one end of the conductive sponge 1 and the ground connection copper foil pass through welded connecting.

In some embodiments, the conductive sponge is in the form of a column, and cross section is round or regular polygon, good to ensure to have Even distribution.In practical operation, it can flow through size of current according to what is be calculated and determine 1 both ends end face institute of conductive sponge The contact area that need to reach.

As shown in figure 4, even if the utility model when being grounded metal plate inclination, can also rely on the compressibility of conductive sponge It realizes and is in close contact with ground connection metal plate, to realize good ground connection purpose.

It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended Claim limit.
