Abstract
The utility model discloses an improved earphone plug which comprises a top end conduction conical surface, a first conduction cylindrical surface, a second conduction cylindrical surface and a third conduction cylindrical surface, wherein radii of middle parts of the first conduction cylindrical surface, the second conduction cylindrical surface and the third conduction cylindrical surface are smaller than the radii of two ends of the respective cylindrical surface, and thus a space for buffer pressure is provided for the conduction of the conduction cylindrical surfaces of the earphone plug and earphone socket contact mechanisms, and an effect of protecting the earphone socket is achieved.
Description
Technical field
The utility model relates to a kind of headset plug, relates in particular to a kind of headset plug that can protect earphone socket.
Background technology
At present, the headset plug circulated on market, the radius of its conducting cylinder each several part is identical, it can produce comparatively strong pressure to the contact mechanism of earphone socket after injecting earphone socket, after long-time the use, certain expendable distortion can occur in the contact mechanism of earphone socket.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of headset plug with buffering earphone socket contact deformation is provided, and reaches the purpose of protection earphone socket.
The utility model solves the problems of the technologies described above the technical scheme adopted: this headset plug comprises the top conducting conical surface (1), the first conducting cylinder, the second conducting cylinder and the 3rd conducting cylinder, the radius at these conducting cylinder middle parts is less than the radius at its two ends, forms the level and smooth annular indent that a degree of depth is not more than 1 millimeter.The transient mode that described conduction column radius surface changes is smooth manner.
Compared with prior art, the beneficial effects of the utility model are: the annular indent that conducting cylinder middle part forms, for the contact mechanism of conducting cylinder and earphone socket connects the space that a compensator or trimmer pressure is provided, had both kept connecting, and had also protected earphone socket.
The accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure: the top conducting conical surface 1; The first conducting cylinder 2; The second conducting cylinder 3; The 3rd conducting cylinder 4
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
In accompanying drawing, the top conducting conical surface 1, the first conducting cylinder 2, the second conducting cylinder 3 and the 3rd conducting cylinder 4 are separated by with insulating tape, each conducting cylinder middle part radius is less than the two ends radius, the mode of radius change is smooth excessiveness, with this its middle part, form an annular indent, its two ends and whole cylinder are consistent.After the utility model plugged earphone socket; each conducting cylinder middle part forms and contacts with the contact mechanism of earphone socket; the annular female parts of utilizing conducting cylinder middle part to form provides an elastic buffer space; both maintained normal connection effect; also avoid earphone socket contact mechanism be subject to strong pressure and occur to be out of shape slowly, thereby reached the purpose of protection earphone socket.
Claims (3)
1. improve headset plug for one kind, comprise the top conducting conical surface (1), the first conducting cylinder (2), the second conducting cylinder (3) and the 3rd conducting cylinder (4), it is characterized in that: the radius at described the first conducting cylinder (2), the second conducting cylinder (3) and the 3rd conducting cylinder (4) middle part is less than the radius at its two ends.
2. headset plug according to claim 1 is characterized in that: the transient mode that described conduction column radius surface changes is smooth manner.
3. headset plug according to claim 1 is characterized in that: the difference of described conducting cylinder two ends radius and its middle part radius is not more than 1 millimeter.
