Embodiment
Just combine accompanying drawing that the present invention is done further introduction below.
Like Fig. 1 a is continuity test process flow diagram of the present invention, and process is following:
Step 1A: tested cable system is connected with interconnecting device by shown in Figure 2, and wherein, cable system comprises two terminals; The whole short circuits of connector contact with one of them terminal; With test lead corresponding link to each other of the connector on another terminal with interconnecting device, said interconnecting device comprises test lead and common port, and is inner at interconnecting device; Test lead and said common port link to each other through switch is corresponding one by one, utilize switch to control being communicated with of test lead and common port.If for the complicated long cable network of satellites transmits pylon, cable network terminal connector on the pylon is used the whole short circuits of dead-short-circuit head, the n of a cable system terminal is connected to test lead on the interconnecting device under launching tower.
Step 1B: utilize the short circuit head to carry out short circuit the common port of above-mentioned interconnecting device, simultaneously will with the same signal of transmission in cable system and to connect the corresponding test lead of connector closed.
Step 1C: choose the arbitrary contact of test lead in the interconnecting device as reference point, the loop resistance value that utilizes the multimeter datum mark is as the reference point resistance.During test, multimeter is selected " automatic range " ohms range, uses the optional interconnecting device test lead of negative test pencil a bit as reference point, and the optional interconnecting device test lead of positive test pencil a bit carries out the reference point resistance as reference point loop point and measures.
Step 1D: select tested connector, the test lead contact that utilizes multimeter to measure to link to each other with tested connector and the resistance of reference point are as testing resistance.It is constant that the negative test pencil of multimeter is plugged on the above-mentioned datum of choosing, the positive test pencil of multimeter be placed on and connect in any point measurement cable system of the corresponding test lead of connector and connect the resistance of transmission signals in the connector.
Step 1E: the test resistance that obtains among the step 1D is deducted the circuit resistance of multimeter test and the actual resistance that said reference point resistance obtains tested connector signal contact, confirm the conducting state of tested connector signal according to the actual resistance of tested connector signal contact.
Fig. 1 b is an Insulation test process flow diagram of the present invention, and process is following:
Step 2A: with tested cable system by the test lead that the connector correspondence at a terminal is connected to interconnecting device shown in Figure 3.For the cable system on the launching tower, can the cable system terminal on the satellites transmits pylon be connected to the interconnecting device test lead, utilize the dead-short-circuit head to carry out short circuit the interconnecting device common port.
Step 2B: with the whole short circuits of the common port of interconnecting device, and the CS between test lead on the interconnecting device and common port is all closed, be communicated with corresponding test lead and common port.
Step 2C: utilize megohmmeter to the inspection of insulating of whole test leads.In insulation inspection, comprise the inspection of the insulation between connector and connector housings and and connect the insulation inspection between connector.Corresponding test lead is as occurring and connecing the connector contact in test process; Then the insulation of megohmmeter is designated as conducting state; Up to and interface all break off; The megohmmeter indication just can be shown as state of insulation, and connector is glutinous to be connected and off-state as in test process, occurring, and this method of testing can both be verified.Guarantee the safety and reliability of cable system.
During test, utilize megohmmeter " 250V " voltage gear, the negative test pencil of the megohmmeter public termination point of any interconnecting device of pegging graft is constant; The positive test pencil of megohmmeter is connected to and patches on the body contact in the cable system; Measure the insulativity of the whole connector contacts of cable system, observe the megohmmeter indication, be designated as " ∞ " plug shell; The expression normal phenomenon does not have signal and package case short circuit.Utilize the positive test pencil of megohmmeter to be connected on the tested contact of interconnecting device test lead, break off the corresponding signal contact simultaneously, the megohmmeter pointer is fallen after rise to " ∞ " by conducting state automatically, representes that this signal isolation is normal, and this test signal and all the other whole signals do not have short circuit phenomenon.
Traditional insulation test method can only carry out man-to-man Insulation test with the contact on the connector, measures number of times to be: (n-1)+(n-2)+... + [n-(n-1)], wherein, n is the connector number of contacts.Data volume is loaded down with trivial details; And can not embody in the cable system and connect connector and other connectors between insulativity; If a large amount of and contact connector of existence at this moment in the cable system, interface breaks off because poor insulativity causes also, and this method of testing can not be verified the also integrity of interface.Above-mentioned insulation test method adopts near-end short circuit one-to-many, many-to-one test, and near-end refers in the cable system of complicated difficult operation, can select arbitrarily that end easy to operate relatively carries out Insulation test in the end, dirigibility is good.One-to-many refers to the Insulation test of single transmission signals path and multiway transmission signal, and many-one refers to multichannel and connects signal and the Insulation test of one-channel signal.Therefore, adopt the present invention to reduce the loaded down with trivial details property of test, testing time is smaller or equal to n time, and cable system and contact are many more more complicated, tests simply more, and the measurement number of times is few more, saves time more.The cable radical is thousands of in the large scale system cable system, and the limb of compiling is complicated, and terminal interface connector number kind quantity also is various; The contact of each connector is different, for one 50 core contact entirely independently connector need carry out 1250 tests according to traditional insulation test method, and adopt insulation test method according to the invention; Only need 50 tests get final product, further, if existence and connect connector in the 50 core connectors; Measure test less than 50 times; And contact is many more, and it is few more to measure number of times, can verify and connect simultaneously connector and situation about connecing under the insulate parallelly connected integrity of inspection.
The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
