An input module comprises n single-pole double-throw switch (SPDT) and 2 single-pole n-throw switch, the fixed port docking of 2 single-pole n-throw switch, n single-pole double-throw switch (SPDT) is connected respectively with the input selection port of a single-pole n-throw switch, the input selection port of the single-pole n-throw switch that is not connected with single-pole double-throw switch (SPDT) is as the delivery outlet of input module, and n single-pole double-throw switch (SPDT) is as n input port of input module.
An output module comprises the single-pole n-throw switch that is connected with the delivery outlet of input module and the dc-dc converter that is connected with this single-pole n-throw switch fixed port, with the delivery outlet of the dc-dc converter delivery outlet as output module, select port as the input port of output module for the n of single-pole n-throw switch.
Interlock between the two states of single-pole double-throw switch (SPDT): COM-NC connection, the COM-NO connection two states, only have a kind of connected state to exist; N single-pole double-throw switch (SPDT) in each unit group interlocks in the section at one time, namely only have a single-pole double-throw switch (SPDT) to be in the COM-NO connected state, remaining is the COM-NC connected state, adopt single-pole n-throw switch to connect between input module and the output module, to same input, only have one the tunnel to be conducting, also only have one the tunnel to be conducting for same output.
Described n is 4 or 6.According to different test environments and test process, select different matrix size, realize the test that once changes the outfit to different test processs by changing the n value.
The present invention compared with prior art has following advantage and beneficial effect:
A kind of matrix switch of 1 the present invention is changed into n time change the outfit once and to be changed the outfit, and has reduced the number of times that changes the outfit, and has reduced the testing time.
A kind of matrix switch of 2 the present invention can realize that the selector switch of multi-to-multi switches arbitrarily, has reduced the wiring in traditional multi-to-multi selection mode.
A kind of matrix switch of 3 the present invention can be expanded according to demand, forms the more matrix of number of channels, satisfies more multichannel demand.

Fig. 1 is electronic devices and components connection diagram of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited to this.
Embodiment
As shown in Figure 1
Of the present invention a kind of matrix switch comprises the matrix that is made of n*n n input module and n output module, and n is 〉=2 natural number.As required, size that can the selection matrix switch, i.e. what of port number are realized the switch matrix of n*n.The n value is set to 4 in the present embodiment.
Described input module has 4 input interfaces and 4 output interfaces, and output module has 4 input interfaces and an output interface, and 4 output interfaces of an input module connect respectively at the input interface of 4 output modules.Consist of a unit group by an input module and an output module, this unit group has 4 input interfaces and an output interface.Consisted of the matrix of 4*4 by 4 input modules and 4 output modules.
An input module comprises 4 single-pole double-throw switch (SPDT)s and 2 hilted broadsword 4 throw switches, the fixed port docking of 2 hilted broadsword 4 throw switches, i.e. COM port docking; 4 single-pole double-throw switch (SPDT)s are connected respectively with the input selection port of hilted broadsword 4 throw switches, the input selection port of hilted broadsword 4 throw switches that are not connected with single-pole double-throw switch (SPDT) is as the delivery outlet of input module, and n single-pole double-throw switch (SPDT) is as n input port of input module.What be connected with single-pole double-throw switch (SPDT) is first order hilted broadsword 4 throw switches, and what be connected with output module is second level hilted broadsword 4 throw switches.
An output module comprises the single-pole n-throw switch that is connected with the delivery outlet of input module and the dc-dc converter that is connected with this single-pole n-throw switch fixed port, with the delivery outlet of the dc-dc converter delivery outlet as output module, select port as the input port of output module for the n of single-pole n-throw switch.
