Abstract
The utility model discloses data in a kind of GPS device to draw shielded cable, cable contains 5 connecting lines, 5 connecting line one end are connected with the data being fixed on an apparatus casing draw socket, three in 5 connecting lines connect a data pin for data wire, data pin is used to connect control circuit board, other two in 5 connecting lines are power outlet, draw socket to the length of data pin is 140 to 150mm, and two power outlet terminations to the length of draw socket are 130 to 140mm；Three data lines are separately each arranged side by side with two power outlets, are cased with magnet ring respectively before and after three data lines and two power outlets each every single line of same position, the spacing of front and rear magnet ring is 10mm；Of the present utility model simple in construction, the electromagnetic compatibility parameter of the structual shield cable can meet FCC authentication requesting.
Description
Technical field
It the utility model is related in a kind of GPS device data and draw shielded cable, especially for GPS handsets from control
Making sheet draws shielded cable to the data of Instrument shell.
Background technology
Need the data of measurement being drawn out to the socket of housing in GPS handsets, in order to the reading of other equipment, such as
Socket directly can be welded to connect by fruit with common practice with control panel, can so reduce the interference of circuit, but such a
Way limits the circuit design of wiring board, has also limited to the installation site of wiring board in the housing, it is therefore desirable to a cable
On the plug for setting data guiding on housing from wiring board, but magnetic field or other signals how are controlled to do cable
It is a kind of selection to disturb just pendulum practical shielding line with radome in face of designer, but is not can have preferable shielding
Line is selected quite well to application person, therefore whether has the jamproof screen method of another leader cable.
The content of the invention
The purpose of this utility model is to propose that data draw shielded cable in a kind of GPS device, by being covered in cable
Magnet ring, and magnet ring are reasonably laid out the anti-interference shielding for realizing leader cable.
To achieve these goals, the technical solution of the utility model is：Data draw shielding electricity in a kind of GPS device
Cable, cable contain 5 connecting lines, and 5 connecting line one end are connected with the data being fixed on an apparatus casing draw socket, and 5
Three in root connecting line connect a data pin for data wire, and data pin is used to connect control circuit board, 5 connecting lines
In other two be power outlet, the length of draw socket to data pin is 140 to 150mm, two power outlets
Termination to the length of draw socket is 130 to 140mm；Three data lines are separately each set side by side with two power outlets
Put, magnet ring is cased with respectively before and after three data lines and two power outlets each every single line of same position, it is front and rear
The spacing of magnet ring is 10mm.
Scheme is further：The ferrite bead that the magnet ring is a diameter of 2.39mm, length is 7.5mm.
Scheme is further：Three data lines are pricked three data lines using binding between front and rear magnet ring side by side
It is together that front and rear magnet ring is stable separately.
The beneficial effects of the utility model are：Simple in construction, the electromagnetic compatibility parameter of the structual shield cable can meet
FCC authentication requesting.
The utility model is described in detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Data draw shielded cable in a kind of GPS device, and as described in Figure 1, the cable contains 5 connecting lines, 5 connections
Line one end is connected with a data draw socket 1 for being used to be fixed on apparatus casing, and 5 connecting line tip positions pass through binding
2 positioning are fixed, and three in 5 connecting lines connect a data pin 4 for data wire 3, and data pin is used to connect control line
Road plate, other two in 5 connecting lines are power outlet 5, and the length of draw socket to data pin is 140 to 150mm,
Two power outlet terminations to the length of draw socket is 130 to 140mm；Three data lines and two power outlets
Separate and be each arranged side by side, distinguish before and after three data lines and two power outlets each every single line of same position
Magnet ring 6 is cased with, the spacing of front and rear magnet ring is 10mm.
In embodiment：The magnet ring is diameter（External diameter）The ferrite bead for being 7.5mm for 2.39mm, length,
Inductance value during 300MHz is 1240mh.
In embodiment：Three data lines are pricked three data lines one using binding 2 between front and rear magnet ring side by side
Rise front and rear magnet ring is stable separately.
The electromagnetic compatibility parameter of the present embodiment structual shield cable can meet FCC certification.
