Description
Technical field
Electronic technology field is the utility model is related to, more specifically, is related to a kind of plug.
Background technology
Headset plug has a variety of structures, wherein, after the completion of the moulding injection on the outside of contact pin, it is also necessary in moulding
Outside one external mold of injection molding, or cap bag is arranged on the outside of moulding again, cap bag can be that plastic product can also be metal
Product.In order to not affect the appearance, the external diameter of general cap bag can be less than normal, and is fixed on by glue on the outside of moulding.
Existing moulding structure is relatively simple, with after the gluing fixation of cap bag, be only capable of by glue provide bonding force, by
Limited in charging capacity of the contact pin (or moulding) between cap bag, tensile test reliability therebetween is relatively low, makes for a long time
During, the risk that cap bag comes off be present.
A kind of for this reason, it may be necessary to new type of plug, it is ensured that the tensile test between contact pin and cap bag meets product reliability requirement,
Prevent product excessive glue or come off.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of plug, and to solve, current plug reliability is low, covers
The problems such as cap easily comes off, product service life is short.
Plug provided by the utility model, including contact pin, the moulding that is moulded on the outside of contact pin, and it is set in moulding
The cap bag in outside；One end of moulding is provided with back-off structure, the storage glue being distributed in dentation is provided with the surface of moulding
Structure；Cap bag is housed in back-off structure and storage plastic structure with moulding by gluing fixation, the glue of fixed cap bag and moulding
It is interior.
Furthermore it is preferred that structure be that back-off structure includes being symmetricly set on two back-off grooves of moulding both sides, fixed cover
The glue of cap and moulding is housed in back-off groove.
Furthermore it is preferred that structure be that storage plastic structure includes spaced and regular distribution groove and bar is stupefied, fixed cap bag
It is housed in the glue of moulding in groove.
Furthermore it is preferred that structure be the rectangular cross-section structure or oat tail groove structure of groove.
Furthermore it is preferred that structure be that storage plastic structure is provided with least two groups, storage plastic structure is evenly distributed on the table of moulding
On face.
Furthermore it is preferred that structure be that cap bag is inserted on the outside of moulding from contact pin side, along the length direction of contact pin, cap bag
Size be not less than moulding size.
It was found from technical scheme above, plug of the present utility model, back-off structure is set on moulding and in dentation
The storage plastic structure of distribution, the glue of fixed cap bag and moulding are housed in back-off structure and storage plastic structure, can not only increased
Glue-spread between cap bag and moulding, additionally it is possible to increase the bonding force of glue, duplicate protection prevents cap bag from coming off, and meets product
The reliability requirement of tensile test.
Brief description of the drawings
By reference to the explanation below in conjunction with accompanying drawing, and with being more fully understood to of the present utility model, this practicality is new
The other purposes and result of type will be more apparent and should be readily appreciated that.In the accompanying drawings：
Fig. 1 is the partial structural diagram according to the plug of the utility model embodiment.
Reference therein includes：Contact pin 1, moulding 2, back-off structure 3, storage plastic structure 4, data wire 5.
Identical label indicates similar or corresponding feature or function in all of the figs.
Embodiment
For plug of the present utility model is described in detail, specific embodiment of the utility model is carried out below with reference to accompanying drawing
It is described in detail.
Fig. 1 shows the plug partial structurtes according to the utility model embodiment.
As shown in figure 1, the plug of the utility model embodiment, including contact pin 1, the moulding 2 for being moulded in the outside of contact pin 1,
And it is set in the cap bag (not shown) in the outside of moulding 2；To improve the adhesion between cap bag and moulding 2, noting
One end of plastic 2 is provided with back-off structure 3, be provided with the surface of moulding 2 in dentation be distributed storage plastic structure 4, cap bag with
Moulding 2 is housed in back-off structure 3 and storage plastic structure 4 by gluing fixation, the glue of fixed cap bag and moulding 2.
Specifically, back-off structure 3 includes two back-off grooves for being symmetricly set on the both sides of moulding 2, fixed cap bag and injection
The glue of part 2 is housed in back-off groove, and the setting of back-off groove can increase glue-spread, additionally it is possible to increases glue and moulding 2
Contact area, prevent cap bag from departing from moulding 2.Wherein, back-off groove is it can also be provided that multiple circular mouldings are set
Glue groove or hold glue ledge structure, can house glue, increase the bonded area of moulding and glue.
Further, it is stupefied including spaced and regular distribution some grooves and bar to store up plastic structure 4, it is whole to store up plastic structure 4
In the structure of similar " washboard ", the glue of fixed cap bag and moulding 2 be housed in bar it is stupefied between groove in.Wherein, groove
Setting number or spacing distance can be adjusted according to the size and product requirement of moulding, the groove can be provided with
The structure of similar back-off groove, it can also be provided that more dry the strip structure of regular distribution or the groove of laciniation
Deng.
In an embodiment of the present utility model, the rectangular cross-section structure or oat tail groove structure of groove,
The glue being housed in groove forms a mutually spacing structural relation with groove, and coordinating back-off structure 3 to be formed prevents cap bag
The double shield to come off.
It should be noted that to ensure the stress equalization between cap bag and moulding 2, storage plastic structure 4 is provided with least two
Group, storage plastic structure 4 are evenly distributed on the surface of moulding 2.In the assembling process of contact pin 1, cap bag is inserted in note from the side of contact pin 1
The outside of plastic 2, along the length direction of contact pin 1, the size of cap bag is not less than the size of moulding 2, so as to which the entirety of moulding 2 be wrapped
It is rolled in cap bag, it is ensured that plug overall appearance, prevent that internal core is exposed.
In another embodiment of the present utility model, also set up in one end of contact pin 1 of the moulding away from flat
Have a data wire 5, one end of data wire 5 is connected conducting with contact pin 1, the other end of data wire 5 can set earphone, interface or its
His terminal device etc..
Plug provided by the utility model can be seen that by above-mentioned embodiment, on the one hand by storing up plastic structure increase
The contact area of moulding and glue, cohesive force of the increase glue to moulding；On the other hand back-off knot is increased in moulding
Structure, it can not only prevent contact pin from being come off from cap bag, additionally it is possible to can play dual guarantor after glue and moulding bonding failure
Shield, prevents cap bag from coming off.
Described in an illustrative manner above with reference to accompanying drawing according to the utility model proposes plug.But this area skill
Art personnel should be appreciated that the plug proposed for above-mentioned the utility model, can also not depart from the utility model content
On the basis of make various improvement.Therefore, the scope of protection of the utility model should be determined by the content of appended claims.
