Abstract

The invention relates to a push button, especially for electric control devices. According to the invention, a plunger is used which comprises rolled bellows that are injection molded thereon in a two component method. As a result, a push button is produced which exhibits significantly improved features with regard to sealing against dirt and moisture.

Description

Button
Technical field
The present invention relates to as the described button of independent claims preorder and especially instruct the device button.
Background technology
The command device button is early known.This button in fact by a shell that constitutes by two parts, one in the enclosure straight line move and flexibly mounted button mast and the volume film that can be fixed on the mast constitute.
Such structure is disclosed in the prior art.
Summary of the invention
Task of the present invention provides a kind of its manufacturing and function (sealing) obtains further optimized button.
According to the present invention, on the basis of the button of the above-mentioned type, finished above-mentioned task by the feature of independent claims 1 characteristic, and dependent claims has provided favourable improvement project of the present invention.According to the present invention, like this structure of design volume film, promptly it as the thermoplastic shaping material in same mould with the mast moulding material simultaneously (time lag is extremely short) be injected in the mould and around the mast injection mo(u)lding.Here, mast material and volume membrane material are so to select, and promptly adhering to does not mutually appear in these two kinds of materials.In a particularly preferred embodiment of the present invention, Merlon is used as the mast material, and styrene-ethylene-butylene-styrene (SEBS piece) is used as the volume film.When mast is formed with sizable groove, having obtained best being rigidly connected connects as shrinking, the size of described groove is so to determine, the last volume film edge of promptly horn-like volume film condenses in mast groove zone clearly by the volume membrane material and experienced best material contracts.So the cohesion of the material of the last volume film edge that obtains advantageously than it in the high twice of volume diaphragm area.On the one hand, button of the present invention can simply and effectively be made, and on the other hand, compares with conventional push button, and it has guaranteed best dustproof and waterproof sealing.
Description of drawings
From the embodiment that describes below in conjunction with accompanying drawing, other details of the present invention and advantage have been obtained.
Fig. 1 is a possible embodiments of having drawn button of the present invention with longitudinal section.
Fig. 2 be with perspective view drawn mast shown in Figure 1 and the volume film.
Fig. 3 is with the mast shown in Figure 2 that drawn of the longitudinal section along the A-A line.
The specific embodiment
As shown in Figure 1, button of the present invention bipartitely namely has upper casing 2 Hes by one The mast 6 of traveling priority and one is on a large scale in the enclosure for the shell of lower casing 4, one Be arranged on volume film 10 on the mast 6 and that be used for capsul inside and consist of, described upper casing and lower casing can Being threaded connection or kayser connects and is connected with each other, described mast 6 can resting position with Mobile between the operating position, and bear on the contrary the elastic force of a spring 8 with its direction of operating.
Mast 6 becomes in fact hollow cylinder, and the one end becomes to be used for the circular lid of manual operation button Face 6a shape, and the other end is used for operating contact structure (not shown), and be formed with court Outer collar shape convex shoulder 6b is so that side card and being bearing on the shell. 8 one-tenth coil spring shapes of spring also And round the mast body. In this case, spring 8 is bearing in convex shoulder 6b and mast under the collar shape On the mast body between the annular bearing 6c of body. Bearing 6c advantageously is designed to annular ground Widen the form of mast body, and it has one in its outer face opposite with the shell wall that centers on The road holds the annular groove of another seal.
Volume film 10 preferably becomes horn-like. According to the present invention, mast 6 and volume film 10 are according to two compositions Injection molding technology is made, and wherein so selects to be used for the plastics of mast 6 and volume film 10, and namely mast 6 Be not bonded to each other with volume film 10. Thus one, guaranteed the best open and flat situation of volume film 10. Mast 6 has one considerably for the annular groove 12 that holds to roll up film regularly, and this is favourable . The size of groove 12 depends on the tool of production (injection mould), is so to determine, namely rolls up film 10 Material cohesion in groove 12 zones is at least than high twice in all the other zones. Thus one, bright Show and improved being connected or closure between mast 6 and the volume film 10, and and then between these two parts, obtain Got stronger sealing property. In same injection moulding process, produce these two parts also thus One they are installed simultaneously is favourable. Thereby, omitted a volume film 10 and the most accurately be positioned at Independent installation steps on the mast 6.
Fact proved, in mast-volume film compound mode, with Merlon as the mast material also It is very favorable that SEBS is used as the volume membrane material.
Fig. 2 is with perspective view drawn mast 6 and volume film 10.
In Fig. 3, can be clear that different materials distributes in the zones of different of volume film 10. Distribute by the volume membrane material of determining, realized that advantageously material is motivatedly at some volume film 10 Contraction in the zone (I, II). Thus one, improved mast 6 and volume at regional I on the one hand Sealing between the film 10 on the other hand, has further been improved open and flat in the regional II of volume film 10 Performance. Especially for open and flat performance, different mast 6 materials and volume film 10 materials of volume film It is indispensable that material does not adhere to mutually.
The present invention is not limited to above-described embodiment, has in meaning of the present invention but comprised all The embodiment of same function. Therefore, certainly also looked out the material that employing has above-mentioned performance Compound mode or mast 6 and volume film 10 are designed to the design of other geometry.
