Abstract
The utility model discloses a kind of diodes; including diode body; and it is arranged at the pin of diode body both sides; the diode body includes outer packaging layer and the chip being arranged inside outer packaging layer; the pin is arranged at the both ends of chip, and the outer packaging layer both sides are each provided with a protective cover, and one end of the protective cover is pasted with outer packaging layer to be connected; the other end is provided with a silica gel sheath, and the silica gel sheath is closely installed on the pin of both sides.The diode of the utility model; two protective covers that can be stretched are provided in outer packaging layer both sides; pin can be effectively so protected in transport, and can prevent secured power of the pin in bending, the situation for preventing pin from twisting at all with chip and damaging.
Description
Technical field
The utility model is related to a kind of diodes.
Background technology
In current electronic component, diode is as the most common accessory of electronic component, since diode is with whole
Function is flowed, therefore, is widely used on various electronic components, there are many current existing diode species, the most frequently used
Diode be that main including chip and to be coated on the shell of chip exterior, being equipped with PN in chip ties, and shell is noted by plastic cement
It moulds, the pin being connected with chip is equipped at the both ends of shell.
Existing diode, in packaging, due to existing diode, shell is mostly cylindric, and diode is being packaged
Shi Rongyi is rolled, it is therefore desirable to the transport of diode is adjusted, often set various knots to diode
Structure, very trouble.Furthermore the pin of diode needs bending in welding, during bending, if pin bending angle
Greatly, it is the damage for be easy to causeing very much chip or external protection such as along root bending.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of diode, using the telescopic protection in both sides two
Cover, efficiently solves deficiency of the prior art.
The utility model is achieved through the following technical solutions：A kind of diode, including diode body, Yi Jishe
The pin of diode body both sides is placed in, the diode body includes outer packaging layer and the core being arranged inside outer packaging layer
Piece, the pin are arranged at the both ends of chip, and the outer packaging layer both sides are each provided with a protective cover, one end of the protective cover
It pastes and connects with outer packaging layer, the other end is provided with a silica gel sheath, and the silica gel sheath is closely installed on the pin of both sides.
As preferred technical solution, the protective cover is telescopic gauffer set, and electro-insulating rubber is used to be made.
As preferred technical solution, one end of the protective cover is both provided with a changeover portion, the tapered shape of the changeover portion.
As preferred technical solution, one end of the silica gel sheath is fixedly connected with outer packaging layer, and other end part is stretched out
In the outside of protective cover.
The beneficial effects of the utility model are：The diode of the utility model, can there is provided two in outer packaging layer both sides
With flexible protective cover, pin can be effectively so protected in transport, and can prevent secured power of the pin in bending,
The situation for preventing pin from twisting at all with chip and damaging.
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.
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 diode body 4 and it is arranged at the pins 1 of 4 both sides of diode body, diode body
2 are arranged at the both ends of chip, outer packaging layer both sides including outer packaging layer and the chip being arranged inside outer packaging layer, pin 1
A protective cover 3 is each provided with, one end of protective cover is pasted with outer packaging layer to be connected, and the other end is provided with a silica gel sheath 2, silica gel sheath
2 are closely installed on the pin 1 of both sides.
Wherein, protective cover 3 is telescopic gauffer set, and electro-insulating rubber is used to be made.One end of protective cover is both provided with
One changeover portion 5, the tapered shape of the changeover portion.One end of silica gel sheath is fixedly connected with outer packaging layer, and other end part stretches out in guarantor
The outside of shield.
In transport, the silica gel sheath of protective cover outboard end is pulled out, wraps up pin as far as possible, is made for protection pin
With.In welding, silica gel sheath is pushed back, making protective cover, the setting of silica gel sheath can effectively be prevented close proximity to intermediate external protection
The only transition bending of pin protects internal chip.
The beneficial effects of the utility model are：The diode of the utility model, can there is provided two in outer packaging layer both sides
With flexible protective cover, pin can be effectively so protected in transport, and can prevent secured power of the pin in bending,
The situation for preventing pin from twisting at all with chip and damaging.
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.
