Description
Technical field
The present invention relates to the interworking testing fields of machine disk and backboard, and in particular to a kind of contact of machine disk and the mutual timing of backboard
Stroke-measuring method.
Background technique
When machine disk and backboard interworking (i.e. the process of machine disk insertion backboard), the connection terminal of the connector of backboard and machine disk
(connection terminal of backboard is straight public needle, and the connection terminal of machine disk is curved female terminal), can never contact condition (Fig. 1-1, i.e. machine disk
With the connection terminal of backboard not in contact with), to starting contact condition (Fig. 1-2, i.e. machine disk start to contact with the connection terminal of backboard),
Steady contact state (Fig. 1-3, i.e. machine disk contact stabilization with the connection terminal of backboard) is arrived again, finally arrives locking state (i.e. machine disk
It is fixed with the connection terminal of backboard, machine disk and backboard are locked).The connection terminal of machine disk is opened from the corresponding position of steady contact state
Begin, terminates to the corresponding position of locking state, be exactly the contacting travel of machine disk and backboard.
If the contacting travel of machine disk and backboard is excessive (connection terminal is partially long), stronger antenna can be generated under high frequency condition
Effect, this is not suitable for high speed transmission of signals；It, can be because a variety of in practical application if contacting travel is too small (connection terminal is partially short)
Cooperation and mismachining tolerance, the problems such as causing contact reliability decline or even do not contact at all.
It follows that the contacting travel of machine disk and backboard is extremely important for the reliability of communication equipment, it is short and effective
Antenna effect of the contacting travel under high frequency condition is weak, is conducive to high speed transmission of signals, is also beneficial to reduce the volume of connector,
To reduce the volume of communication equipment and improve transmission capacity.In order to guarantee that the reliability of communication equipment, relevant criterion require letter
Number effective contacting travel of connector is not less than 0.51mm；When the contacting travel of machine disk and backboard and effective contacting travel have differences
When, need the size to machine disk connector to be adjusted.
Currently, the method for the contacting travel of test machine disk and backboard are as follows: machine disk be inserted into backboard during, when backboard with
When the connection terminal of the connector of machine disk is in steady contact state, the distance between measuring machine disk and backboard a, when backboard and machine
When the connection terminal of the connector of disk is in locking state, the distance between measuring machine disk and backboard b obtain machine disk according to a and b
With the contacting travel c, c=a-b of backboard.The condition that the contacting travel that the above method measures is consistent with traveled distance are as follows: 1, backboard
Measuring surface with machine disk is plane (just can guarantee the actual c of a-b=in this way)；2, it accurately learns that connection terminal is in be steadily contacted
The position of state.
But backboard and machine disk can cause not exclusively to be plane because there are deviations for processing and installation cooperation in practice,
And it is empirically determined (because being invisible when connection terminal contact that connection terminal, which is in the position of steady contact state,
).Therefore, in the above method and condition that traveled distance is consistent has deviation, so that the contacting travel finally measured
Resultant error is larger, not only low measurement accuracy, but also measurement request is higher, is not suitable for using the lesser high speed of contacting travel
The machine disk and backboard of signal connector.
