Description
Technical field
The utility model relates to ear phone technology fields, and in particular to one kind is anti-to pull apart earphone.
Background technique
In present life, everywhere it can be seen that the figure of earphone, takes an examination at home, in outdoor, various English Listening Comprehension
Etc., it all can't do without earphone.Till now from invention, the progress also with people's science and technology develops earphone constantly.With when
Between development, earphone products hang over from two earliest small speakers and have gradually moved to maturity in one's ear.Whether the type of earphone
Or wearing mode, or even to the pronunciation unit of core, there is many changes, but have on earphone and often earphone cable is pulled
Break, especially the junction of earphone cable and plug.
Utility model content
In view of the above shortcomings of the prior art, the utility model provide it is a kind of anti-pull apart earphone, in earphone cable and plug
Junction setting is anti-to pull apart portion, and the conducting wire at this is made to be not easy to be torn.
To achieve the above objectives, the present invention adopts the following technical solutions:
One kind is anti-to pull apart earphone, including plug, earphone cable, earplug, further includes the junction for being set to plug and earphone cable
It is anti-pull apart portion, the anti-portion of pulling apart includes shell, and earphone cable right-to-left passes through shell, and the right end and plug of the shell connect
It connects；The left side of the shell is equipped with the through-hole that passes through for earphone cable, in shell the upper and lower sides of the through-hole be respectively equipped with outside
The vertical guide rod in the left side of shell, limit plate is connected between two guide rods, and the upper and lower side of limit plate is respectively equipped with for upper
The through-hole that lower two guide rods pass through, limit plate can vertically two guide rods move left and right；The right end of the guide rod is equipped with
Block prevents limit plate to be detached from guide rod；The earphone cable passes through limit plate, and fixes with limit plate；The limit plate and insert
The straight length of earphone cable between head is longer than the maximum distance between limit plate and plug.
Further, spring, the spring are equipped between the inner wall of the left side of the left side and shell of the limit plate
It is sheathed on guide rod, left and right ends are individually fixed in the inner wall of the left side of shell and the left side of limit plate；Spring not by
When power, limit plate is located at the right end of guide rod.
The utility model has the advantages that when earphone cable left end is pulled by external force, earphone cable is moved downward along through-hole, and then earphone cable band
Dynamic limit plate movement, limit plate move downward inside the shell along guide rod, are depressed into limit position when limit plate moves to spring
When setting, spring prevents limit plate from continuing to move, and then the earphone cable between limit plate and plug is in redundant state, to avoid
The junction stress of earphone cable and plug, achievees the purpose that anti-dropout with this, solve original earphone lack it is anti-pull apart function,
Earphone cable and plug junction crack conditions, reliability poor problem are easy to appear when being pulled by external force.Simultaneously as spring
A part of external force is consumed, the stress of earphone cable Yu limit plate junction is alleviated.
Detailed description of the invention
Fig. 1 is the anti-structural schematic diagram for pulling apart portion；
Fig. 2 is the structural schematic diagram of earphone；
Figure label: 1, earphone cable；2, spring；3, plug；4, shell；5, guide rod；6, limit plate；7, earplug.
Specific embodiment
The utility model is described further below with reference to embodiment.
The utility model increases on the basis of existing earphone to be prevented pulling apart portion, to the original mode of connection of existing earphone, function
Energy, material are without any change.The anti-outer casing for pulling apart portion can be integrally designed with plug, and appearance seems that only size is slightly
Change.
As shown in Figure 1, the anti-portion of pulling apart includes shell 4, the right end connection plug 3 of shell 4, left side is equipped with for earphone cable 1
The through-hole passed through.It is equipped with upper and lower two guide rods 5 in shell 4, is located above and below through-hole.It is provided on limit plate 6
Upper and lower two through-holes, upper and lower two guide rods 5 are each passed through two through-holes, limit plate 6 up and down and can move along guide rod 5 or so
It is dynamic.The right end of guide rod 5 is equipped with block, and limit plate 6 is prevented to be detached from guide rod 5.Earphone cable 1 pass through limit plate 6, and with limit
Plate 6 is fixed.The straight length of earphone cable 1 between limit plate 6 and plug 3 be longer than between limit plate 6 and plug 3 it is maximum away from
From.Spring 8 is equipped between the inner wall of the left side of the left side and shell 4 of limit plate 6, spring 8 is sheathed on guide rod 5, left
Right both ends are individually fixed in the inner wall of the left side of shell 4 and the left side of limit plate 6.When spring 8 does not stress, limit plate 6
In the right end of guide rod 5.
Shell 4, guide rod 5, limit plate 6 material can be metal or rigid plastics.The anti-specific structure size for pulling apart portion
It can customize as needed.
When 1 left end of earphone cable is pulled by external force, earphone cable 1 is moved downward along the through-hole of 4 left side of shell, Jin Erer
Machine line 1 drives limit plate 6 to move, and limit plate 6 moves downward in shell 4 along guide rod 5, when limit plate 6 moves to spring
2 when being depressed into extreme position, and spring 2 prevents limit plate 6 from continuing to move, and then at the earphone cable 1 between limit plate 6 and plug 3
In redundant state, to avoid the junction stress of earphone cable 1 Yu plug 3.After external force disappears, spring 2 restores to the original state, and drives limit
Position plate 6 is restored to origin-location.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not limited to this hair the foregoing is merely a specific embodiment of the invention
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
