For the technical scheme making those of ordinary skill in the art be more fully understood that in this utility model, and
Above-mentioned purpose of the present utility model, feature and advantage are enable to become apparent from understandable, the most right
Technical scheme in each embodiment of the present utility model elaborates further.
Referring to Fig. 1, in one embodiment, a kind of signal connects and transmitting device 100, and it is applied to bag
Containing the external equipment of multiple pins, such as, it can be applied to photographic head module, it is also possible to is applied to refer to
Stricture of vagina identification module.
This signal connects and transmitting device 100 includes a test board 110, and test board is provided with multiple input
Pin 150, multiple output pin 170 and and multiple input pin 150, output pin 170 phase respectively
Multiple adapters 130 even.
More preferably, test board 110 is pcb board, input pin 150, output pin 170 on pcb board
Method of attachment with adapter 130 can use joint welding of the prior art, boxing, spot welding etc., at this
Repeat no more.
Wherein, multiple adapters 130 formation one line-column matrix arranged in rows in a row, input pin 150 He
Output pin 170 lays respectively at the adjacent edge of line-column matrix.By any one in short circuit line-column matrix
Intersection point so that the signal of external equipment input can be via the input of arbitrary input pin and via arbitrary output
Pin exports.
As in figure 2 it is shown, line-column matrix includes adapter 231 that lateral separation arranges and longitudinally spaced row
The adapter 233 of row, then input pin 250 can be connected with the adapter 231 of lateral separation arrangement,
Output pin 270 can be connected with the adapter 233 of longitudinally spaced arrangement, and the company of lateral separation arrangement
The adapter 235 connecing device 231 public with the adapter 233 of longitudinally spaced arrangement is in line-column matrix
One intersection point.
By arranging as above in test board, pin defines the letter that different each external equipments is inputted
Number can be by any input and output of the line-column matrix in test board, it is only necessary to the difference in short circuit line-column matrix
Intersection point, without changing test board, thus substantially increases testing efficiency, and significantly reduces
Testing cost, is particularly suited for producing manufacture test board in enormous quantities.
According to different application scenarios, the signal of external equipment input can derive from photographic head module or
Fingerprint recognition module, this utility model is not limited thereto.Hereafter deriving from photographic head module with signal is
Example, connects signal and transmitting device is explained.
In one embodiment, multiple input pins and output pin are divided into two input and output pin groups, and first
Input and output pin group is corresponding to one of them photographic head of photographic head module, the second input and output pin group
Another photographic head corresponding to photographic head module.
In the present embodiment, comprising two photographic head in photographic head module, such as, one of them photographic head can
For shooting human eye scene in one's power, another photographic head can be used for autodyning.
After multiple input pins and output pin are divided into two input and output pin groups, the first input and output
Pin set comprises multiple input pin and output pin, in order to transmit the letter of one of them photographic head output
Number；Second input and output pin group comprises remaining multiple input pin and output pin, another in order to transmit
The signal of one photographic head output.
It should be noted that the quantity often distributing input pin and the output pin obtained in group is taken the photograph from different
As defined in head, pin number matches.
Such as, comprising photographic head A and photographic head B in photographic head module, photographic head A defines 10
Pin, photographic head B defines 15 pins, then corresponding to first input and output pin of photographic head A
Group comprises 10 input pins and 10 output pins, corresponding to second input and output of photographic head B
Pin set comprises 15 input pins and 15 output pins.
It is to say, test board is respectively arranged at least 25 input pins and output pin, by row
Those input pins and output pin are interconnected by the adapter of column matrix, and then make photographic head A and shooting
The signal of head B output can by corresponding arbitrary input pin output and be drawn by corresponding arbitrary output simultaneously
Foot exports, and without carrying out the replacing of test board, is effectively improved the testing efficiency of photographic head module.
Further, referring to Fig. 3, in one embodiment, device 300 as above also includes one
Handover module 390, in order to draw in the first input and output pin group and the second input and output according to switching signal
Switch between foot group so that in photographic head module, the signal of only one of which photographic head output can be via switching
Module 390 exports to external test facility 410.
Wherein, switching signal can directly be inputted by external test facility 410, it is also possible to is as above
Described device 300 is generated by the trigger action of response test personnel.
Such as, as shown in Figure 4, device 300 as above is provided with and electrically connects with handover module 390
The switching switch 391 connect, when tester operates switching switch 391, and switching switch 391 will be to switching mould
Block 390 sends the switching signal corresponding with this operation so that handover module 390 enters according to this switching signal
The switching behavior that row is corresponding with this switching signal.
More preferably, handover module 390 is MIPI switch chip.This MIPI switch chip includes multiple
One pin and multiple second pin, the first pin interconnects with output pin, and the second pin sets with external testing
Standby connected.
It is known that owing to MIPI interface has more low-power consumption, higher data transmission rate and less PCB
Take up room, existing photographic head generally uses MIPI interface, be beneficial to carry shooting head mould
Communication between optimization and those smart machines of the smart machine of group connects.If in photographic head module
There are two photographic head, so that the MIPI signal of only one of which photographic head output in photographic head module
Can export to external test facility, need the clock pins of MIPI interface and data pin and connect,
And using the signal of the RST pin of MIPI interface or the output of PWDN pin as switching signal.
This kind of the prior art arranges the two-way that two photographic head inputs may be caused to handover module 310
MIPI signal impedance does not mates or interferes, thus affects the parallel transmission of two-way MIPI signal,
Make photographic head module test instability, and then cause external test facility 330 can not get normal shadow
Picture.
By test board is arranged as above, the two-way MIPI letter of two photographic head outputs will be made
Number can input independently of each other to handover module 390 without interfering, then by handover module 390
Wherein a road MIPI signal switching will export to external test facility 410, thus be effectively improved shooting
The reliability of head mould group test.Simultaneously, additionally it is possible to support all photographic head with two MIPI interfaces
Module, without changing test board, reduces testing cost, improves testing efficiency.
Foregoing, preferred embodiment the most of the present utility model, it is not intended that and this utility model is protected
The restriction of scope.Any made within spirit of the present utility model and principle amendment, equivalent and
Improve, within should be included in protection domain of the present utility model.
