Description
Technical field
The utility model is related to a kind of new audions.
Background technology
The effect of triode is that small-signal is zoomed into the larger electric signal of amplitude, is now widely used for broadcast, electricity
Depending on, communicate, the fields such as radar, calculator, self-con-tained unit, electronic instrument, household electrical appliance.
Triode possesses more pin, needs to protect three pins using various means when dispatching from the factory transport, causes to transport
Seek the increase of cost.
In addition, triode in the later stage in use, heat is higher, the heat needs at pin distribute, and general encapsulated layer dissipates
The aperture of hot hole is smaller, first, being afraid of that dust is fallen into, influences to radiate, second is that entrance afraid of water, damages chip, therefore, heat dissipation performance
It is constantly subjected to limit.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of new audions, can be stretched by setting one
The protective cover of contracting effectively solves deficiency of the prior art.
The utility model is achieved through the following technical solutions：A kind of new audion, including triode body,
Three-level tube body includes external encapsulated layer, internal chip and three pins being arranged on chip, encapsulated layer and is arranged at core
The outside of piece, three pins are exposed to the outside of encapsulated layer, the bottom of the encapsulated layer be located at pin one side set there are one with
On heat emission hole, set outside the encapsulated layer of pin one side there are one telescopic protective cover, the front end face of protective cover is close
It seals, is set at the protective cover sealed bottom there are three silica gel sheath, the silica gel sheath is tightly placed on every pin, the protection
More than one air hole is provided on cover.
As preferred technical solution, the protective cover is rubber gauffer set, and the guarantor of a closing is formed among protective cover
Protect chamber.
As preferred technical solution, the protective cover includes rubber layer and metal layer, every two pieces of rubber layers it
Between a metal layer is set, in " v " font, the metal layer is in linear type in the section of the rubber layer.
As preferred technical solution, the metal layer is heat dissipation aluminium layer, and air hole may be contained on metal layer.
The beneficial effects of the utility model are：The utility model is simple in structure, sets a protective cover that can be stretched, can
Three pins are effectively protected in transport, ensure that it is not bent over, and expand the heat emission hole on encapsulated layer, are completed in welding
A protective layer is formed using protective cover afterwards, prevents external dust from entering heat dissipating layer and plays the role of waterproof, and protective cover
It is very practical with heat sinking function.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial structural diagram of the protective cover of the utility model；
Fig. 3 is the bottom substance schematic diagram of the triode of the utility model.
Specific embodiment
All features or disclosed all methods disclosed in this specification or in the process the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and attached drawing）Disclosed in any feature, except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.I.e., unless specifically stated, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, including triode body 1, three-level tube body 1 includes external encapsulated layer, internal chip and setting
In three pins 3 on chip, encapsulated layer is arranged at the outside of chip, and three pins 3 are exposed to the outside of encapsulated layer, encapsulated layer
Bottom be located at pin one side and be provided with more than one heat emission hole 8, as shown in Figure 3.
Telescopic protective cover 2 there are one being set outside the encapsulated layer of 3 one side of pin, the front end face of protective cover 2 are close
It seals, is set at 2 sealed bottom of protective cover there are three silica gel sheath 4, silica gel sheath 4 to be tightly placed on every pin 3, be set on protective cover 2
It is equipped with more than one air hole 7.In transport, protective cover pulls out, for protecting three pins, during welding, by three
Silica gel sheath is promoted towards inner end, you can is exposed pin, is realized welding.
As shown in Fig. 2, wherein, protective cover 2 is rubber gauffer set, the protection chamber of a closing is formed among protective cover.It protects
Shield includes rubber layer 5 and metal layer 6, sets a metal layer 6 between every two pieces of rubber layers 5, the section of rubber layer 5 is in
" v " font, metal layer 6 are in linear type, and metal layer 6 is heat dissipation aluminium layer, and air hole 7 may be contained on metal layer.Metal layer is used
It is used in heat dissipation and heat absorption, after the completion of welding, can effectively help to radiate, and the heat emission hole of encapsulated layer bottom can be accomplished
Maximum by being provided with protective cover, can effectively prevent the entrance of dust and the entrance of water, add security, and solve
Heat dissipation problem.
The beneficial effects of the utility model are：The utility model is simple in structure, sets a protective cover that can be stretched, can
Three pins are effectively protected in transport, ensure that it is not bent over, and expand the heat emission hole on encapsulated layer, are completed in welding
A protective layer is formed using protective cover afterwards, prevents external dust from entering heat dissipating layer and plays the role of waterproof, and protective cover
It is very practical with heat sinking function.
The above is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
