Description
Technical field
The invention belongs to technical field of electronic equipment, and in particular to a kind of logic analyser sonde configuration and production side
Method.
Background technique
Logic analyser is the instrument for analyzing digital display circuit logical relation, acquires and shows from equipment under test using clock
Digital signal is mainly used for the judgement of timing.Logic probe structure is the important component of logic analyser, mainly realizes quilt
Object is surveyed to connect with the signal of logic analyser host.
Logic probe is made of the first hub, the second hub and connection-peg, and the first hub passes through flat cable
It is connect respectively with second hub, the second hub passes through more separately positioned cables and connection-peg.
It has been recognised by the inventors that existing logic probe structure has the disadvantages that
1) the upper lower casing assembly of existing first hub, the second hub is connected using screw, because shell material is quality
Softer ABS+PC, and wall thickness is partially thin, when being assembled using screw, the degree tightened is not easy to accurately hold, determine one it is suitable
There is also difficulty for torque, and that often twists tightly can cause housing distortion too big very much, tighten inadequate and easy generation screw in use
It loosens.
2) the second hub part needs for a branch of flat cable to be divided into 8 tunnels, and existing separated time guide post has to be led well
To function, but when practical set, often pliability is inadequate for cable, and when separated time finishes installation upper cover, needing to push down cable prevents it
Warpage is unsceptered, and operation has difficulties.
3) connection-peg part-structure is compact, and connector and cable are welded in printed board, and printed board passes through inside upper and lower shell
The position limiting structures positioning such as boss, the structure type that connector is closed up using fluting.In real work, connector and printed board it
Between solder joint and cable and printed board between solder joint can be stressed directly, the welding force of solder joint should be greater than external contact pin and connector
To it is slotting when contact engaging and separating force and have certain allowance.But frequently under the external factor collective effect such as plug and vibration, connection-peg part
It is easy to appear poor electric contact even solder joints to disengage.
Summary of the invention
The first object of the present invention is to provide a kind of logic analyser sonde configuration, is able to solve in existing probe connector
Assembly precision is poor between first hub and the upper housing and lower case of the second hub, is difficult to ensure the qualified problem of assembly；
It solves the problems, such as in the second hub because assembly efficiency caused by cable tilts is low；It is able to solve connection-peg and the second collection simultaneously
The poor contact and desoldering problem caused after solder joint stress in line device.
The production method that the second object of the present invention is to provide a kind of logic analyser sonde configuration, instructs logic analysis
The production of instrument sonde configuration.
A kind of logic analyser sonde configuration, including first collection the end of a thread, described first collection the end of a thread is for connecting logic point
Analyzer；It is described first collection the end of a thread in the first printed circuit board and cable-assembly one end weld, the other end of cable-assembly with
The second printed circuit board welding in second connector, the cable-assembly include multiple First Lines for being arranged side by side and being fixed to each other
Cable；Second printed circuit board is welded with one end of more second cables respectively, separately positioned between more second cables；Often
In the other end of a second cable and a connection-peg third printed circuit board welding, the other end of third printed circuit board with
Connector connection, the connector are used for connecting contact pin；The connection-peg be it is multiple, each connection-peg is with unifying second cable
It uses.
It is equipped with the first cable fixinig plate in described second collection the end of a thread, the both ends of the first cable fixinig plate are respectively with second
The shell of collection the end of a thread is fixedly connected, and the extending direction of the first cable fixinig plate is vertical with the extending direction of cable-assembly, institute
The first cable fixinig plate is stated to be fixedly connected with each of cable-assembly the first cable respectively.
In the connection-peg be equipped with the second cable fixinig plate, the both ends of the second cable fixinig plate respectively with connection-peg
Shell is fixedly connected, and the extending direction of the second cable fixinig plate is vertical with the extending direction of the second cable, second line
It is fixedly connected between cable fixinig plate and the second cable.
Being fixed to each other between the first cable and the second hub is realized using the first cable fixinig plate, using the second line
Cable fixinig plate realizes being fixed to each other between the second cable and connection-peg, and pad is only used for realizing electrical connection, plug probe
When structure, solder joint, the second cable between the first cable and the second printed board and the solder joint between third printed board do not stress,
It avoids because plugging solder joint poor contact and desoldering phenomenon caused by sonde configuration repeatedly.
Extending direction using the first cable fixinig plate is vertical with the extending direction of the first cable, the second cable fixinig plate
The extending direction mode vertical with the extending direction of the second cable.When plug probe, the first cable fixinig plate and the first cable it
Between fixed point, the fixed point uniform stressed between the second cable fixinig plate and the second cable, reduce what fixed point disengaged
Probability.
