In order to overcome the deficiencies in the prior art, the utility model provides a kind of connector notebook adapter, plug better effects if that is applied to.
The utility model solves the technical scheme that its technical problem adopts:
A kind of connector that is applied to notebook adapter, comprise header body, be positioned at the inserted link and the terminals that are positioned at header body rear end of header body front end, described inserted link has jack, wherein said jack includes null line hole product, live wire hole and earth connection hole, described inserted link is connected with header body by the plug internal frame that is positioned at header body front end, wherein said jack extends to plug internal frame rear end, described jack is built-in with plug terminal, described plug terminal includes cylindrical body and is positioned at the wiring tail end of cylindrical body rear end, the front portion of described cylindrical body is provided with interior closing waist concave arc.
As a preference, the rear end of described plug internal frame is provided with the V-type demarcation strip that can separate jack.
As a preference, the left and right end portions of described V-type demarcation strip and middle knuckle place are respectively arranged with reinforced column.
As a preference, the interior closing waist concave arc place of described cylindrical body has cannelure.
As a preference, described V-type demarcation strip is provided with to the demarcation strip concave arc of receiving in centre.
As a preference, the place of holding of described header body rear end is provided with spline-simulating protuberance.
The beneficial effects of the utility model are: this plug is by rational structural improvement; particularly match with plug terminal by the plug internal frame of header body front end; when plug terminal is inserted into after internal frame; plug terminal is not subject to the variation of injection pressure in the time of injection moulding; guarantee the stability of contact engaging and separating force; in addition the V-type partition plate structure of plug internal frame further improves the structural strength of plug internal frame; especially the structural strength of plug internal frame rear end jack position; further protection plug terminal, ensures plug quality.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1, Fig. 2 are the STRUCTURE DECOMPOSITION figure of plug internal frame in the utility model;
Fig. 3 is stereogram of the present utility model.
Embodiment
With reference to Fig. 3, a kind of connector that is applied to notebook adapter, comprise header body 1, be positioned at the inserted link 2 of header body 1 front end and be positioned at the terminals 3 of header body 1 rear end, described inserted link 2 has jack 4, wherein said jack 4 includes null line hole 41, live wire hole 42 and earth connection hole 43, and finished product word shape is arranged in null line hole 41, live wire hole 42 and earth connection hole 43.Terminals 3 have net tail and avoid power supply to damage because of bending.The place of holding of described header body 1 rear end is provided with spline-simulating protuberance 11, feel when plug is held in raising and the aesthetic feeling of plug itself.
With reference to Fig. 1, Fig. 2, described inserted link 2 is connected with header body 1 by the plug internal frame 5 that is positioned at header body 1 front end, wherein said jack 4 extends to plug internal frame 5 rear ends, described jack 4 is built-in with plug terminal 6, described plug terminal 6 includes cylindrical body 61 and is positioned at the wiring tail end 62 of cylindrical body 61 rear ends, the front portion of described cylindrical body 61 is provided with interior closing waist concave arc 63, makes the insertion force of plug more even, is not subject to the variable effect of plug injection moulding pressure.Interior closing waist concave arc 63 places of described cylindrical body 61 have cannelure 64, make the processing of interior closing waist concave arc 63 easier.
Wherein plug internal frame 5 can adopt PBT material, adopts exposed structure, being i.e. embedded in header body 1 of a part of plug internal frame 5.Both sides up and down in header body 1 are designed with pattern area 12.
The rear end of described plug internal frame 5 is provided with the V-type demarcation strip 7 that can separate jack 4, further improve the solidness of plug, minimizing is the impact on plug insertion force because plug is out of shape, and V-type demarcation strip 7 also can play the effect of separating power line in plug, the chance of minimizing short circuit.The left and right end portions of described V-type demarcation strip 7 and middle knuckle place are respectively arranged with reinforced column 71, further improve the structural strength of V-type demarcation strip 7.Described V-type demarcation strip 7 is provided with to the demarcation strip concave arc 72 of receiving in centre, and ingenious jack 4 shapes of avoiding, can save space, make plug internal frame 5 more compact structure.
In the time of actual production, its step is as follows:
1. electric wire 13, through peeling opening, carries out riveting operation with three plug terminals 6 respectively;
2. the plug terminal 6 that then riveting is good seals in respectively three jacks 4, i.e. null line hole 41, live wire hole 42 and earth connection hole 43;
3 in the time of assembling, and three cores of electric wire have V-type demarcation strip 7 to separate, and produce short circuit to prevent that three copper wires on polarity terminal from touching together.
