Abstract
The utility model discloses a wire rod seal structure, include the one set of seal structure who constitutes by centre form and external mold, the centre form is the bullet head structure, leave an aperture in the middle of the centre form, heart yearn skin 1.6mm in the centre form front end free accommodation wire rod, centre form rear end free accommodation wire rod outer layer line skin 2mm make the centre form forms a whole with the outer layer line skin of wire rod, the external mold is wrapping up the centre form. The utility model discloses a reserve an aperture the centre form in the middle of, when preventing that the wire rod heart yearn from moulding plastics in the mould, be stressed and the extrusion of plastics leads to the fact the short circuit, and heart yearn skin 1.6mm glues in order to seal in the centre form front end free accommodation wire rod, and the outer layer line skin 2mm of rear end free accommodation wire rod makes the outer layer line skin of centre form and wire rod form a whole, can be better prevent gas leakage.
Description
Technical field
The utility model relates to a kind of wire rod hermetically-sealed construction.
Background technology
As everyone knows, USB data line is widely used on the equipment such as mobile phone, mouse, modulator-demodulator, keyboard, MP3, digital camera and portable hard drive, can be described as modern live in the middle of indispensable product.In the production injection moulding process of data wire, heart yearn is stressed and the extruding of plastics is easy to cause short circuit, and how data wire better keeps the sealing of data wire to prevent it from leaking gas in injection moulding process, and this also will affect USB data line function and use.
In view of this, the present inventor studies and devises a kind of wire rod hermetically-sealed construction, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of wire rod hermetically-sealed construction be made up of internal mold and external mold, by reserving an aperture in the middle of the internal mold, preventing heart yearn when in-mould injection, to be stressed and the extruding of plastics causes short circuit, and there is good sealing, prevent gas leakage.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of wire rod hermetically-sealed construction, comprises a set of hermetically-sealed construction be made up of internal mold and external mold; Described internal mold is sub warhead structure, an aperture is left in the middle of described internal mold, described internal mold front end encases wire rod internal core wire skin 1.6mm, and described internal mold rear end encases the outer layer line skin 2mm of wire rod makes described internal mold and the outer layer line skin of wire rod form an entirety, and described external mold is wrapped in described internal mold.
As the optimal way of embodiment, described internal mold is that PP material is one-body molded.
As the optimal way of embodiment, described external mold is that TPE material is one-body molded.
Because a kind of wire rod of the utility model hermetically-sealed construction have employed above-mentioned technical scheme, namely comprise a set of hermetically-sealed construction be made up of internal mold and external mold; Described internal mold is sub warhead structure, an aperture is left in the middle of described internal mold, described internal mold front end encases wire rod internal core wire skin 1.6mm, and described internal mold rear end encases the outer layer line skin 2mm of wire rod makes described internal mold and the outer layer line skin of wire rod form an entirety, and described external mold is wrapped in described internal mold; Make heart yearn of the present utility model when in-mould injection, can not be stressed and plastics extruding and cause short circuit, sealing can also be facilitated and better prevent wire rod from leaking gas, good sealing effect.
Accompanying drawing explanation
Fig. 1 is the utility model cutaway view.
Fig. 2 is the utility model internal model structure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, a kind of wire rod hermetically-sealed construction, comprises a set of hermetically-sealed construction be made up of internal mold (1) and external mold (2); Described internal mold (1) is sub warhead structure, an aperture (3) is left in the middle of described internal mold (1), described internal mold (1) front end encases wire rod internal core wire skin 1.6mm (4), described internal mold (1) rear end encases the outer layer line skin 2mm (5) of wire rod makes the outer layer line skin (5) of described internal mold (1) and wire rod form an entirety, and described external mold (2) is wrapped in described internal mold (1).
As the optimal way of embodiment, described internal mold (1) for PP material one-body molded.
As the optimal way of embodiment, described external mold (2) for TPE material one-body molded.
In the present embodiment, for 2 heart yearns.The utility model by reserving an aperture in the middle of wire rod internal mold, prevent core wires when in-mould injection, to be stressed and the extruding of plastics causes short circuit, it is in order to sealing that internal mold front end encases wire rod internal core wire skin 1.6mm, rear end encases the outer layer line skin 2mm of wire rod makes internal mold and the outer layer line skin of wire rod form an entirety, can better prevent gas leakage.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
Claims (3)
