One or two housing components 5,6 of housing 2 are especially made up of plastic material by polymeric material and at this aptly.This, housing component 5,6 can particularly simple and cost advantages ground without cutting ground manufacture.Additionally, diaphragm driver 1 has only only small weight in this case.It is to be understood, however, that metal embodiment is also possible, wherein, housing component 5,6 especially manufactures by aluminum or by high-quality steel.Also can be realized by composite.
The two housing component 5,6 is fixed to one another by means of bayonet mount 45 in an advantageous manner.In order to set up bayonet connection, they in second step can be made in the front earth's axis relative to each other to rotate to being plugged together with opening 7a, 7b facing each other the two housing component 5,6 in the first step.The direction being axially plugged together overlaps with the axial of longitudinal axis 3.Rotation axis for rotary motion is directly formed by longitudinal axis 3.
Bayonet mount 45 releasably constructs aptly.Therefore, can pass through motor process (first reversely rotating and then drawn apart from one another) in turn makes the two housing component 5,6 from unclamping each other when needed.
The built-in edge 14 of tensioning between end wall 5a, 6a of the two side of the diaphragm 13 being made up of the material with caoutchouc elasticity characteristic at least in part is responsible for the necessary axial pretightening between the two housing component 5,6 aptly.
Bayonet mount 45 has the first locking projection 46a being arranged in the first housing component 5 place and is arranged in the second locking projection 46b at the second housing component 6 place.When setting up bayonet connection, the first and second locking projection 46a, 46b are followed by mutually on the side being axially facing each other.Being particularly characterised in that of bayonet mount 45, locking projection 46a, 46b in the state fitted together of housing 2 by the two housing component 5,6 to cover from the sightless mode of each viewing angle or to hide here from the outside.Obtaining the outline of diaphragm driver in like fashion, it is less susceptible to contaminated, and it is very easy to clean and is not caused by the danger of parts that are that expose especially and that be likely to sharp rib by it.
The two housing component 5,6 axially invades one another when co-axial orientation in its engaging zones.Exemplarily, the end wall 6a of the side of this second housing component 6 its length at least some of on radially surrounded by the annular sidewall 5b of the first housing component 5 outside.Namely it can be said that the annular sidewall 5b of the first housing component 5 is in outside in engaging zones, and the annular sidewall 6b of the second housing component 6 is radially in the inside.The other explanation of bayonet mount 45 also realizes according to this situation.It is to be understood, however, that the association in turn of housing component 5,6 is also possible so that annular sidewall 5b axially invades in annular sidewall 6b.
The annular sidewall 5b of the first housing component 5 has coaxial in longitudinal axis 3, ring-type the first carrying intercept 47a.The radially inner side place of the first carrying intercept 47a it is arranged in hereinafter also referred to the first locking projection 46a of outer locking projection.Multiple first or outer locking projection 46a longitudinal axis 3 week up along first carry intercept 47a arrange with being distributed to phase mutual spacing to each other.Correspondingly, the first circumference carrying intercept 47a produces between the outer locking projection 46a that follows one another respectively, not only axially but also axially towards the gap inwardly opened wide, be called external series gap 48a below.In the first circumference carrying intercept 47a, therefore outer locking projection 46a and external series gap 48a arranges with following one another.
The annular sidewall 6b of the second housing component 6 has the second carrying intercept 47b of ring-type, and it is coaxially arranged in longitudinal axis 3 equally.It axially upwardly is stretching out to the side of the first housing component 5.Be arranged in the radial outside place of the second carrying intercept 47b of ring-type hereinafter referred to as the second locking projection 46b of interior locking projection, wherein, its quantity is corresponding to the quantity of outer locking projection 46a.Exist between interior locking projection 46b adjacent respectively in the second circumference carrying intercept 47b and be axially toward the first housing component 5 and simultaneously axially towards outwardly open gap, be called internal clearance 48b below.In like fashion, carry the multiple interior locking projection 46b and internal clearance 48b in intercept 47b place second alternately to follow one another with being distributed in the circumferential layout.
The circumference of carrying intercept 47a, 47b refers to the extension of the longitudinal axis 3 around housing 2.
First carrying intercept 47a has the first end face 52a of the axial ring-type towards the second housing component 6 orientation.Second carrying intercept 47b has the second end face 52b of the ring-type of axial orientation in its end towards the first housing 5.Outer locking projection 46a is directly coupled to the first end face 52a place aptly, and interior locking projection 46b is directly coupled to the second end face 52b place aptly.
There is channel-shaped gap 53a, 53b between the intercept put corresponding thereto at each locking projection 46a, b and associated housing component 5,6, its first housing component 5 situation central diameter upwardly toward interior and in the situation central diameter of the second housing component 6 up towards outwardly open.Channel-shaped gap 53a, 53b are transitioned in gap 48a, 48b of connection respectively in the circumference of carrying intercept 47a, 47b.
