Technical field

The present invention relates to a kind of housing and a kind of audiphone or hearing aids that is used for audiphone or hearing aids.

Background technology

Audiphone or hearing aids have the housing or the housing outer cover of a sealing when work usually.Because receive a series of environmental impact during these instrument work, be under situation about constituting, also must be sealed shut by a plurality of parts so these housings had both made.So only received the personnel of training just can open these housings by means of special instrument and through corresponding.

If but during operation or under the situation that the short time interrupts when working, interfere with the inside of housing and when not needing to open the housing outer cover fully, just must on the housing outer cover, design some closed perforates.This situation possibly be for example must make an electrical plug-in connection that connects that is connected to an external instrument.

In known audiphone, for example in having the audiphone that is worn over the ear back of electronics amplifying technique, designed some corresponding perforates, these perforates can be bearing in the closed with covers on the housing pivotally.The metal shaft that this lid for example passes said lid by means of one and passes the guiding of said housing is fixed.

Though this audiphone has showed a kind of stable interconnection technique, have very high space requirement and because many members and different materials former thereby cause very high manufacturing expense.

In another modification, lid can import in the perforate from the outside, and wherein, lid is equipped with the hinge components in some corresponding recesses that flexibly are engaged to housing.Therefore though cover design is a part, also has this danger, promptly lid is because the operation of infraction of regulations comes off out in the groove and so lose or be damaged.

Another known modification is, can each perforate be closed by means of a lid of for example being processed by rubber of forming through an elastic hinge and elastomeric material.The shortcoming of this modification is, because the elasticity and the elastic characteristic of hinge fraction were automatically shut suddenly or closed automatically before carrying out the interference of having a mind to through said perforate through regular meeting after lid is opened.

Summary of the invention

The objective of the invention is to, invent a kind of housing with lid, said housing does not need very high manufacturing expense and said lid to prevent reliably to remove unintentionally.

According to the present invention; This purpose realizes through a kind of housing that is used for audiphone or hearing aids; This housing has amplify element and at least one design perforate and lid that can cover said perforate on hull outside of the enclosure interior of being located at, and wherein, lid is made up of a part; This part has the pin of outside sensing; And in housing, have the groove that is provided with block, make pin to import to from the inboard of housing in the groove, then be in the backstop state over there through said block towards the outside.

Said lid is a rounding in the zone of pin, preferably has the cylindrical shape in a kind of subregion at least.

Said pin designs on an axle on the lid and preferably has circular cross section.

At a kind of housing that is used for audiphone or hearing aids, have the element that amplifies, at least one design perforate and lid that can cover perforate on the outside of the enclosure interior of being located at.According to the present invention, in this housing, cover design is a part with pin of directed outwards.In addition, have the groove that some are provided with block in the housing, make said pin can import to from the inboard of housing in the said groove, then be in the backstop state over there through said block towards the outside.Therefore this lid can not directly extract from housing or remove forward, therefore stops lid by mistake or independently to get loose reliably.However, it can also be very simple that lid is installed on the housing, for example also can be from installed in front.For this reason, lid must be pushed in the perforate of housing from the front portion under rotation status with its end that is provided with pin, and and then rotation like this, up to the inboard and there unlimited groove entering engagement of said pin from housing.Then, lid can be by pull to its rotary position in housing, normally against the backstop of said groove, and seals said perforate there or through around the gyration of bearing pin opening being opened basically by purpose.Advantageously, lid and pin are made up of an independent part, and therefore can make on simple and inexpensive ground, are for example made economically in enormous quantities by plastics.

Advantageously, lid is a rounding in the zone of pin, and preferably has the cylindrical shape in a kind of subregion at least.Therefore, this zone of lid gets into the backstop state with the wall district of a respective design of housing and supports above that there, and this has caused very high mechanical strength.

Advantageously, the pin design is on an axle on the lid.Therefore, this root axle has also constituted the gyroaxis of lid simultaneously under installment state.The cross section that this preferred pin is had a circle.Therefore, pin also can import in the groove simply and in groove, be pushed into the terminal location of lid.

Advantageously, on housing, arrange at least one flexible connecting plate, said connecting plate under installment state at least subregion and lid preferably in the zone of pin in the entering elastic bolster guide, and the part of the swing hinge of formation lid.Through the elastic construction of this connecting plate, lid can be engaged on the terminal location of regulation and be fixed on then on this position.Simultaneously, lid with the part of connecting plate contact and connecting plate and the pin that in groove, guides together, advantageously constituted a swing hinge jointly.Therefore having constituted one reliably can rotating lid, and it neither can by mistake can independently not come off from its terminal location housing yet.

Advantageously, connecting plate is designed to the part of housing.Connecting plate advantageously directly constitutes one by the part of processing with the housing identical materials, and therefore can be integrated in the version of housing.

Advantageously, housing is made up of the housing outer cover of two mutual removable connections at least, and preferably is made of plastics.Therefore both having made in production in enormous quantities also can be worthwhile and simply make housing.Because housing is to be made up of a plurality of parts, can install simply or assemble so need be arranged on the element and the module of enclosure interior.

According to the present invention, also advised a kind of audiphone or hearing aids in addition with one according to housing of the present invention.
