Abstract
The invention relates to a short-tail headset plug, solving the problem of an overlong tail part of the existing headset plug. The short-tail headset plug comprises a first annular sheet metal, a second annular sheet metal to an Nth annular sheet metal which are coaxially arranged from interior to exterior, and an insulation joint board which is fixed on an annular body of the Nth sheet metal, wherein the plane of the insulation joint board is vertical to the central axis of the annular body of the Nth sheet metal, N-1 bonding pads which are mutually insulated are fixed on the insulation joint board, and the N-1 bonding pads are respectively correspondingly connected to the first sheet metal, the second sheet metal to the N-1th sheet metal through leads. According to the headset plug, the connection strength of each sheet metal and each headset lead is enhanced through adding the insulation joint board. In comparison with the tail part of the existing headset plug, the tail part of the headset plug can be reduced by 5-7 mm so as to be convenient for storage; a front part and a back part of the headset plug are uniformly forced, so that the headset plug and a plug connector are difficult to damage, and thus the service life is prolonged.
Description
Technical field
The invention belongs to earphone field, be specifically related to a kind of headset plug of short-tail.
Background technology
Existing headset plug, comprises the sheet metal of several annulars of coaxial arrangement, is separated between sheet metal by insulating material; For three grades of headset plugs, the quantity of sheet metal is three, is the first sheet metal, the second sheet metal and the 3rd sheet metal from the inside to the outside successively; For the headset plug of level Four, the quantity of sheet metal is four, is the first sheet metal, the second sheet metal, the 3rd sheet metal and the 4th sheet metal from the inside to the outside successively.As Fig. 1, for the headset plug of level Four, the middle part of the 4th sheet metal is generally provided with ledge structure, and the afterbody of the 3rd sheet metal stretches out the afterbody of the 4th sheet metal, the afterbody of the second sheet metal stretches out the afterbody of the 3rd sheet metal, and the afterbody of the first sheet metal stretches out the afterbody of the second sheet metal.Therefore, the total length (length of the first sheet metal) of the headset plug of level Four is longer, anterior (length before ledge structure front end) is 14.2mm, its total length (length of the first sheet metal) is about 24.2mm, and long headset plug makes earphone overall volume larger, not easily contained, and due to headset plug afterbody longer, cause headset plug anterior stressed excessive, easily damage headset plug and pin connector thereof.
Summary of the invention
The present invention, in order to solve the problem in background technology, provides a kind of headset plug of short-tail.
Technical solution of the present invention is:
A kind of short-tail headset plug, to the first sheet metal of the annular of outer coaxial arrangement in comprising, second sheet metal ... and N sheet metal, N be greater than 2 natural number, separated by insulating material between the ring body of each sheet metal, its special character is: described short-tail headset plug also comprises insulation connecting plate, affiliated insulation connecting plate is fixed on the ring body of N sheet metal, the central axis upright of the ring body of insulation connecting plate place plane and N sheet metal, insulation connecting plate is fixed with the bonding pad of N-1 mutual insulating, N-1 bonding pad is respectively at the first sheet metal, second sheet metal ... and N-1 sheet metal is connected one to one by wire, the afterbody of N-1 sheet metal stretches out the afterbody 0.5mm-1.5mm of N sheet metal, the afterbody of N-2 sheet metal stretches out the afterbody 0.5mm-1.5mm of N-1 sheet metal, the afterbody of the second sheet metal stretches out the afterbody 0.5mm-1.5mm of the first sheet metal.
Above-mentioned N sheet metal is fixedly connected with N bonding pad.
Above-mentioned insulation connecting plate is also fixed with the N bonding pad be connected by wire with N sheet metal, and N bonding pad and remaining bonding pad insulate.
Each sheet metal is connected formed bond pad locations to be circumferentially uniformly distributed with wire.
The shape of above-mentioned insulation connecting plate is rectangle, insulation connecting plate on each bonding pad be distributed in insulation connecting plate or be distributed in insulation connecting plate any number of limits on.
Advantage of the present invention is: headset plug of the present invention, by increasing insulation connecting plate, strengthens the bonding strength of each sheet metal and earphone cord.Headset plug afterbody can reduce 5-7mm compared with existing headset plug afterbody, is convenient to storage; Headset plug front and rear part uniform force, not fragile headset plug and pin connector, increase the service life.
Accompanying drawing explanation
Fig. 1 is existing level Four headset plug structural representation;
Fig. 2 is the level Four headset plug structural representation that the present invention improves;
Fig. 3 is bonding pad distribution schematic diagram on connecting plate of the present invention.
Wherein: 1-first sheet metal; 2-second sheet metal; 3-the 3rd sheet metal; 4-the 4th sheet metal; 41-ledge structure; 5-insulate connecting plate; 6-bonding pad; 7-the 4th bonding pad.
Embodiment
The short-tail headset plug of level Four, comprise the first sheet metal of the annular of coaxial arrangement from the inside to the outside, the second sheet metal, the 3rd sheet metal and the 4th sheet metal, separated by insulating material between each sheet metal, first sheet metal, the second sheet metal, the 3rd sheet metal and the 4th sheet metal include ring body, the afterbody of the 3rd sheet metal stretches out the afterbody 0.5mm-1.5mm of the 4th sheet metal, the afterbody of the second sheet metal stretches out the afterbody 0.5mm-1.5mm of the 3rd sheet metal, and the afterbody of the first sheet metal stretches out the afterbody 0.5mm-1.5mm of the second sheet metal.This short-tail headset plug also comprises insulation connecting plate, affiliated insulation connecting plate is fixed on the ring body of the 4th sheet metal, the central axis upright of the ring body of insulation connecting plate place plane and the 4th sheet metal, insulation connecting plate is fixed with the bonding pad of three mutual insulatings, three bonding pads are connected one to one by wire respectively at the first sheet metal, the second sheet metal and the first sheet metal.
The afterbody of the ring body of the 4th sheet metal is provided with ledge structure, ledge structure is provided with the 4th bonding pad, and the 4th bonding pad is used for welding lead, as shown in Figure 2.Prior art is that the middle part of ring body is provided with ledge structure, and the afterbody of ring body, as welding position, causes the 4th sheet metal length of existing headset plug long, present invention saves the length of the afterbody of ring body, saves length 5-7mm.Or insulation connecting plate is also fixed with the 4th bonding pad be connected by wire with the 4th sheet metal, the 4th bonding pad and remaining bonding pad insulate, as Fig. 3.
