Abstract
The utility model relates to a mobile phone maintenance wire with field strength display, which is characterized in that an indicating circuit of the field strength of radio signals of a mobile phone is connected among the input ends of a regulated power supply in parallel. When the utility model is used, a user does not need to use other instruments or take the mobile phone in repair to an ear part to conduct hearing judgment to exactly judge whether the mobile phone can normally work with convenience and visualization.
Description
The utility model relates to a kind of mobile phone maintenance tool, particularly a kind of mobile phone maintenance thread.
Usually, maintenance thread is the one group of lead that contains input that connects stabilized voltage power supply and the interface line end that is connected mobile phone, in when maintenance, plays connection additional power source effect maintenance personal at maintenance process, needs often to check that can mobile phone work.Normally rely on frequency meter or instrument such as special-purpose field strength meter or ammeter to detect this mode and increased many inconvenience to the maintenance personal.In order to address this problem.The designer studies, and existing maintenance thread is improved.Technical solutions of the utility model have been proposed
The purpose of this utility model is to provide a kind of can detect the mobile phone maintenance thread that band field intensity that can the mobile phone that be keeped in repair operate as normal shows.
The utility model considers that maintenance person is when maintenance, all attempt to make mobile phone to receive or the transmission signal, if mobile phone function work, the field intensity that the radio signal generation of mobile phone is then just arranged around mobile phone, by detecting the situation of field intensity around the mobile phone, just can judge that can mobile phone work.For this reason, the utility model takes following technical proposals to realize:
The mobile phone maintenance thread that the band field intensity shows comprises the input that connects stabilized voltage power supply, with the interface line end that is connected mobile phone.Mobile phone radio field strength signal indicating circuit in parallel between the input that connects stabilized voltage power supply.
Use the utility model, maintenance person need not also need not be taken mobile phone Under Repair and carry out sense of hearing judgement in one's ear by Other Instruments, just can judge accurately that can mobile phone operate as normal.Very convenient directly perceived.

With reference to accompanying drawing the utility model is described
(with reference to Fig. 1)
The utility model is on original maintenance thread basis, mobile phone radio field strength signal indicating circuit is parallel to the interface line end two ends that connect mobile phone forms.The main effect of maintenance thread is for the mobile phone that is keeped in repair provides supply voltage, thereby the interface line end of connection mobile phone is and the mobile phone Interface Matching that will keep in repair.The interface line end difference of various types is the interface line end that is applicable to Nokia's mobile phone as Fig. 2, when it provides supply voltage to mobile phone, also need provide reference voltage, and in the necessary hook-type of port, could work.
