Abstract
The utility model relates to an integral type tuning fork changeover plug. The plug comprises a hollow tubular first direct current plug, a hollow tubular second direct current plug, an integrally formed tuning fork sheet, a negative electrode metal sheet and an insulating protection cover; wherein the tuning fork sheet has a first positive electrode slice and a second positive electrode slice which are located at two sides respectively, the first positive electrode slice is sleeved in the first direct current plug, the second positive electrode slide is sleeved in the second direct current plug, the outer wall of the first direct current plug and the outer wall of the second direct current plug are electrically connected with the negative electrode metal sheet, and the negative electrode metal sheet is located in the insulating protection cover. The integral type tuning fork changeover plug uses the integrally formed tuning fork sheet to connect the first direct current plug and the second direct current plug which act as changeover plugs at both ends, so that the process of manual welding is omitted, production cost is reduced, and the integrally formed tuning fork sheet is good in connection, quality and stability of the product are greatly improved, and production efficiency is improved to a certain degree at the same time.
Description
Technical field
The utility model relates to the changeover plug for cellular phone power supplies.
Background technology
Therefore all differences to some extent of power interface due to the various brands mobile phone utilize changeover plug to go for the interface of multiple mobile phone.
Along with the progress of science, portable power source is more and more universal, large screen mobile phone particularly, and power consumption is larger, and therefore a lot of people can use portable power source, use yet the portable power source interface can not satisfy many moneys mobile phone.Therefore use the direct current translation interface can convert easily the attaching plug that is fit to handset port to.
As shown in Figure 1, present DC changeover plug connects anodal as conduction by the tuning fork sheet 51a of two DC plug 2a, 3a, 52a position respectively by welding or caulking part 6a.Outer wall at two DC plugs adds a sheet metal 4 again, and the conduction negative pole that is used for the DC changeover plug is communicated with, and forms plastic body 1a in the middle interconnecting piece position of DC changeover plug by injection moulding at last, in order to protect internal structure.
Above-mentioned DC changeover plug is to connect conduction by two DC plugs by welding or riveted joint, however after this procedure needs artificial clip DC plug, then weld or rivet operation at the tuning fork chip part of minimum area one by one, increased production cost.
The utility model content
The purpose of this utility model is to propose a kind of integral type tuning fork changeover plug, and it can solve the high problem of production cost.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
Integral type tuning fork changeover plug, it comprises the first DC plug of hollow tubular, the second DC plug of hollow tubular, integrated tuning fork sheet, negative pole sheet metal and insulation protection shell; Described tuning fork sheet has the first electrode film, second electrode film of separation both sides; the first electrode film is socketed in the first DC plug; the second electrode film is socketed in the second DC plug; the outer wall of the outer wall of the first DC plug, the second DC plug all is electrically connected with the negative pole sheet metal, and the negative pole sheet metal is positioned at the insulation protection shell.
Preferably, described insulation protection shell is plastic casing.
The utlity model has following beneficial effect:
Utilize integrated tuning fork sheet to carry out first DC plug, second DC plug of two as changeover plug connected, therefore omit artificial this operation of welding, reduced production cost, and integrated tuning fork sheet connectivity is good, product quality and stability are improved greatly, have also improved certain production efficiency simultaneously.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As extremely shown in Figure 5 in Fig. 2, integral type tuning fork changeover plug, it comprises the first DC plug 3 of hollow tubular, the second DC plug 2 of hollow tubular, integrated tuning fork sheet 5, negative pole sheet metal 4 and insulation protection shell 1.
Described tuning fork sheet 5 has the first electrode film 51, second electrode film 52 of separation both sides; the first electrode film 51 is socketed in the first DC plug 3; the second electrode film 52 is socketed in the second DC plug 2; the outer wall of the outer wall of the first DC plug 3, the second DC plug 2 all is electrically connected with negative pole sheet metal 4, and negative pole sheet metal 4 is positioned at insulation protection shell 1.
The insulation protection shell 1 of the present embodiment is plastic casing.Insulation protection shell 1 is for the protection of the internal structure of integral type tuning fork changeover plug.
As shown in Figure 5, the assembling process of the present embodiment is as follows:
Tuning fork sheet 5 is anodal as conduction, be inserted in respectively the first DC plug 3, the second DC plug 2 after injection moulding at the first electrode film 51, the second electrode film 52, the outer wall of the first DC plug 3, the second DC plug 2 all has the layer of metal material, the outer wall of the first DC plug 3, the second DC plug 2 connects negative pole sheet metal 4, is used for as the conduction negative pole.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection range of the utility model claim within.
