Abstract
The utility model relates to a signal converter for a mobile telephone, which comprises a converter main body, a cable wire, a signal plug, etc. A vehicle cigarette lighter provides the power supply. A signal wire of the cable wire transmits the signal. The signal is switched and played by a microphone, an amplifying circuit, a loudspeaker, etc. of the converter main body. The utility model reaches the purpose that the mobile telephone is used without holding. The utility model is characterized in that an insulating wire holding device which is used for connecting the tail end of the converter main body and the cable wire is provided with a small magnetic dust core; the dust core is composed of two semi-cylindrical magnetic dust cores which are sheathed outside the signal wire and are coated and fixed by the insulating wire holding device.
Description
This is novel to be relevant a kind of mobile telephone signal adapter, especially refer to that ring is established the tubulose filter that a bit of magnetic powder is made in a kind of gripping device of the signal connecting line at the mobile phone adapter, so that the magnetic field that is produced on the stabilization signal connecting line, abate the noise, reach its reception of enhancing, and do not influence the effectiveness of outward appearance.
The structure of general prior mobile phone adapter includes compositions such as adaptor body, cable and a Signal plug; On this adaptor body front end, have one and can insert the plug of automobile cigarette lighter, and be provided with microphone, loud speaker and amplifying circuit etc. in it; Signal plug is the terminal with a plurality of marshallings, and can be connected with the signal plug of mobile phone, in addition then has a quite long cable to be connected between above-mentioned adaptor body and Signal plug; When adaptor body is inserted on the automobile cigarette lighter, and after Signal plug inserted mobile phone, can provide power supply by automobile cigarette lighter, and nationality is by the signal wire transmits signal in the cable, and transfer and broadcast by amplifying circuit, microphone and the loud speaker etc. of adaptor body, to reach the purpose of hand-free mobile phone calling.
When using as above-mentioned existing product, because Che Neishang has some electronic equipments, and the interference of engine vibration frequency, will make the switching effect extreme difference of mobile phone, and slacken the practicality of this product; So show improved necessity is arranged again.
The design people is very easily disturbed by extraneous electric wave or seismic wave in use in view of above-mentioned existing product, and influences the various shortcoming of the utility function of this product, through studying intensively for a long time, creates a kind of brand-new mobile telephone signal adapter eventually; Its main purpose is to provide a kind of mobile telephone signal adapter, makes when using the mobile telephone holding-free receiver onboard, causes the noise of instability or external environmental interference but erasure signal line self produces magnetic field, and the user more can clearly be talked.
This novel time purpose is to provide a kind of mobile telephone signal adapter, and the filtering ferrocart core that is wherein installed additional can not influence overall appearance.
For achieving the above object, basis is novel mainly to be provided with a bit of magnetic powder core at the insulation gripping device place that the adaptor body tail end is connected with cable, this ferrocart core is to be linked in mutually outside some holding wires with the hollow magnetic powder core that two semicircular ring form, and is coated and fixed by gripping device again.
According to the above, but this novel mat is coated on the magnetic powder core in the gripping device so that reform by the electric wave at this place, reaching the magnetic field that is produced on the stabilization signal line, and the effect that abates the noise, and then audibility is strengthened, and do not influence its outward appearance.
For making to this novel unitary construction, device, feature and effect thereof, can make further understanding and understanding, the enforcement situation conjunction with figs. with this creation is described in detail as follows now:
Fig. 1 is that illustration is implemented in this novel solid combination;
Fig. 2 is this novel three-dimensional exploded view;
As shown in Figure 1 and Figure 2, comprise compositions such as adaptor body 1, cable 2 and a Signal plug 3; On this adaptor body 1 front end, have one and can insert the plug 11 of automobile cigarette lighter, and be provided with microphone 12, loud speaker 13 and amplifying circuit 14 etc. in it; The terminal of Signal plug 3 for having a plurality of marshallings can be connected with the signal plug of mobile phone; 3 of above-mentioned adaptor body 1 and Signal plugs link to each other with cable 2; When adaptor body 1 is inserted on the automobile cigarette lighter, and with behind the Signal plug 3 insertion mobile phones 4, can provide power supply by automobile cigarette lighter, and by holding wire 21 transmission signals in the cable 2, and by the microphone 12 of adaptor body 1, amplifying circuit 14, and switching such as loud speaker 13 with play, to reach the purpose of hand-free mobile phone calling.
As above-mentioned structure, this novel feature slightly is ' worker ' font at the insulation gripping device 22 that adaptor body 1 tail end is used for being connected and fixed with cable 2, and the outer rim protuberance of adaptor body 1 just can chimeric ' worker ' font the both sides recess, arbitrarily pull and damage to avoid cable 2 and holding wire 21; And when making insulation gripping device 22 in the mould molding mode, coat earlier a bit of magnetic powder core 23 on cable 2 surfaces at this place, this section magnetic powder core 23 is sleeved on mutually outside the cable 2 by two semicolumn magnetic powder cores 23 and becomes the filter configuration of a bit of tubulose; , again in above-mentioned tool magnetic powder core 23 parts in mould molding mode be made into a gripping device 22, and magnetic powder core 23 is coated and be fixed therein thereafter.When implementing, can produce a magnetic field by the above-mentioned magnetic powder core 23 of mat,, abate the noise and reach with the stable signal wave of strengthening by this segment signal line 21 that reaches according to above-mentioned structure, and the purpose that can not influence this mobile phone adapter outward appearance fully.
Embodiment as mentioned above, it only is this novel preferable enforcement situation, only this novel feature is not limited to this, any be familiar with that this technology institute can think easily and equivalence change equal originally novel spirit and creation scopes of genus.
