The output unit is connected to the indicator panel and the display control unit, and the clamp of the body of the monitored product is connected to the control unit.

The drawing shows a structural electrical diagram of the device.

The device contains a control unit 1, registers-counters 2 and 3, a comparison element 4, an output block 5, memory elements 6 and 7, an analysis block 8, a memory block 9, a unit 10 for setting types and numbers of monitored connectors, an indicator board 11, a block 12 printing, simulator 13 connections, display control unit 14, contact selection block 15, output 16 and input 17 control connectors, remote control 18, output 19 and input 20 connectors, output 21 and input 22 adapter cables. The monitored product 23 has connectors 24i, ...., 24p and 25 of its enclosure.

The device works as follows.

Pressing the Reset button stops the device to its original state. The output 21 and input 22 adapter cables are connected to the first pair of connectors of the monitored product 23.

The control unit 1 periodically, with a certain frequency, feeds and removes the distinctive sign from the clamp of the body of the tested product, and using the register-counter 2 - removes and feeds the distinctive signs simultaneously all the contacts of the output connector 19. At the same time, between the contacts of the connectors 24i and 242 products 23 have at least one connection, then at the time of supplying the distinctive features to all the contacts of the output connector 19 and, respectively, to remove the distinguishing sign from the terminal 25 in the memory block 9 using the block 1 Regents of those contacts stored input terminal 20, which are of distinctive features. During the removal of the distinctive features, simultaneously with all the contacts of the output connector 19 and, accordingly, the supply of the distinctive characteristic to the clamp 25, they are reset to the initial state using the control unit 1, the memory elements of the memory block 9 connected to the contacts of the input connector 20 having adapter cable 22 and connector 242 connecting to the housing of the product 23; as a result, distinctive features appear on them. During this cycle, in memory block 9, only those memory elements that correspond to connector pins 242, which are connected to pins 24i and not connected to product housing 23, remain in the memory state. As a result, control unit 1 detects that one memory element of memory block 9 in the Memory status, issues a command to light up the lamp on the connection of the indicator board 11. The operator, when this lamp lights up, gives a start signal for the start of indicacin and printing of the contact connections of the 24i connectors 242, which may be fed or by pressing the "Start, or if necessary to display and print numbers of those connectors and their addresses

contacts with accepted symbols, -

automatically after installation

types and numbers of the controlled pair

connectors using block 10.

After each filing and withdrawal period

The control unit 1 sets the memory unit 9 to the initial state.

Thus, the operator can recognize if there is at least one connection between the contacts 23 of any pair of connectors 24b, ..., 24 that are not closed on the body of the product 23. light of the corresponding lamp of the display panel And when you connect these connectors to the output 21 and input

22 transitional cables, and without the need to press the Start button or the installation of numbers and types of monitored connectors. When a start signal arrives, block 1

control, after memory in memory 9 of all contacts of input connector 20, having a connection through product 23 with contacts of output connector 19 and the body of the product, stops feeding and removing the distinctive features from clip 25 and simultaneously from all contacts of output connector 19, then registers counters 2 and 3 begin to receive counting pulses.

During each state of the register counter 2, the contact of the output connector 19 corresponding to this state is given a distinctive feature which, if there is a connection of this contact with

other contacts of the connected pair of monitored connectors are supplied to these contacts. Each successive counting pulse to the register-counter 2 hits or after the end of two switching cycles

register-counter 3 or after switching register-counter 3 during its every first switching cycle to the state corresponding to that pin of output connector 19, which has a connection

through the controlled product 23 with the contact register selected by the 2 contact of the same connector and preceded by it in the order of consecutive numbering of contacts. The latter allows you to eliminate the repetition of the output on the display and print earlier

proven connections between contacts of a controlled pair of connectors.

The analysis unit 8 during each regenstructor 3 during its first switching cycles determines, through the control unit 1, the presence of a distinctive sign on the contact of the output connector 19 corresponding to this level of the register counter 3, and during its each state during the second switching cycles, it determines the presence of a distinctive sign on the pin of the input connector 20 corresponding to the given state. Upon detection of these distinctive features, analysis block 8 generates signals of a connection, according to which control block 1 generates commands for displaying and printing information from counter registers 2, 3 and block 10 for setting types and numbers of connectors. During the first switching cycles of the register-counter 3, the memory element 6, which is set to the “Signal output from the output of the element 4, compares the coincidence of the register-counters 2 and 3 during these switching cycles, allows displaying and printing only those connections of the contacts of the output connector 19, for which the contact of the output connector 19 selected by the meter register 2 precedes the found contact of the connection. Otherwise, control unit 1 sets register-counter 3 to initial state, memory element 6 and feeds the following counting pulses to register-counters 2 and 3, skipping the found connection as previously checked.

During the second switching cycles of the register-counter 3, the memory element 6, which is set to the Memory in the first switching cycles of the register-counter 3, allows printing of any found connections between the contacts of the monitored pair of product connectors. In addition, during the first switching cycles of the register-counter 3, the signal from the comparison element 4 in the absence of a distinctive feature on the clamp 25 prohibits the display and printing of the contact of the output connector 19 when the states of the counter-registers 2 and 3 coincide.

If there is a connection selected by the register-counter 2 contact of the output connector 19 with the housing of the product 23, a distinctive sign is supplied to the control unit 1, which at the end of the first switching cycle of the register-counter 3 issues a command for indication and printing of the short circuit to the housing and prohibits the second cycle switching, transfer register counter 2 to the next state. This prohibits the repetition of the display output and the printing of contacts closed on the body of that connector of the product 23, which is connected to the input connector 20.

After the end of the display and printing of connections with the selected reg1; pgrom-counter

2-pin output connector 19 block 1 control at the end of the corresponding second cycle of the register register-counter

3 submits the command for outputting the indication of the end of the circuit and the next counting pulse to the register-counter 2.

This control process continues until

until, until the display and printing, all the connections between the connector pins of the product connected to the output connector 19 and between the contacts of this and the second of the monitored

pairs of product connectors.

During the second switching cycles of register-counter 3, when finding the contacts on the indication and printing of contacts, the signals from the control unit 1 are printed

The resetting of the memory elements of the memory block 9 corresponding to the contacts of these connections is reset. In the absence of failures of register-counters 2 and 3, at the end of the control of the pair of product MOBs, complete erasure of the information recorded in block 9 of information memory will occur. If there are failures for connecting the contacts between the monitored connectors for full erasure of the recorded information, the control unit 1 issues a command to light the malfunction lamp on the indicator board 11 and print the malfunction sign. In addition, at the end of the control, the pair of connectors of the product 23 is set to the “Memory storage element 7”, which prohibits the repetition of the display and printing of previously found connections.

between the contacts of that connector of the product that is connected to the output adapter cable 21. When the input adapter cable 22 is connected to the other product connectors, connection registration is allowed only during the second switching cycles of register-counter 3. The control end lamp lights up on the display board. All units of the device, except the memory element 7, are reset to their original state.

Using the input cable 22 c of the lamp of the presence of a connection on the display board 11, a search is carried out for another connector

a product with contacts of which there is at least one such connection of the contacts of the plug connected to the output adapter cable 21, which is not connected to the body of the product. After setting the type and number of the connector found, the connection between the new pair of product connectors is displayed and displayed.

Such operations continue until they check all pairs of product connectors, one connector of which is permanently connected to the output adapter cable 21.

After that, using the Reset button, the entire device is reset, and the entire monitoring process is repeated for the next connector of the product 23 and then in a similar way for all its other connectors until all the possible pairs have been searched, excluding the previously tested connectors from the monitoring process.

At the end of the monitoring, a table of available connections is obtained, excluding their repetition and having the designations of the contact addresses of the connections in the form in which they are accepted for the connectors in the documentation.

The device can operate without a printing unit 12. In this case, information about the connections can be seen on the indicator board II, and the transition from connection to connection when testing one pair of product connectors is carried out by means of the Start button.

By connecting the perforator output unit 5 to the table of available connections in the product, ita punched tapes or punched cards can be applied for use in mass production.

When controlling the installation of the connecting cable, it is connected directly or through the output and input adapter cables to the device's output and input ports.

After installation of the types and numbers of cable connectors, the device will work almost the same way as in the case of interconnect mounting of the electrical connections of the units. The exception is that the comparison element 4 prevents the output for ipdating and breaking the contacts under the same conditions of the register-counters 2 and 3 both during the first and second switching cycles of the register-counter 3, if the analysis block 8 determines the presence of connections these contacts, allows them to be displayed and printed in the absence of such connections, while simultaneously issuing a command to the display using the control unit 1 and printing the sign of the core breakage. In addition, if such a break is detected, the control unit 1, at the end of the corresponding second switching cycle of register-counter 3, issues a command to register-counter 2 to terminate the supply of a distinctive sign to the selected pin of output connector 19, and the connection simulator gives a command to feed this sign to the contact of the same name input connector 20, then delivers counting pulses to the register-counter 3, starting its third switching cycle, and controls the operation of the device in the same way as during the first switching cycle registraschstchpkz 3. During this cycle switching nroiskhodit output to display and print soedipeny simulator 13 compounds selected input connector pin 20 with other contacts of the same connector. Thus, during the first and third switching cycles of the register-counter 3, the display and printing of unnecessary connections — contact closures or cable cores — are performed, and during the second cycles, cable cable breaks, as well as all other connections between cable connectors contacts included in the number of pluggably connected contacts and by whose connections it is possible to track the entire chain of improperly connected contacts. The device health check is provided by the connection simulator, which for each contact of the output connector 19 selected by the register-counter 2 simulates its connection with the previous one and simultaneously with the contact of this connector and the contact of the same connector of the connector 20. After the start of checking the device health, the control unit 1 together with the register - a simulator of 13 connections with a counter 2 n, giving distinctive signs to all contacts of the input connector 20, produces a complete filling of memory block 9, and then It is usual, as in the control of inter-socket wiring of electrical connections of blocks, the search and display of the simulated connections for indication and printing. When the device is working correctly, the indication and printing successively output the addresses of the contacts of the circuits, each of which contains one contact of the input connector 20, one of the same name and one next contact of the output connector 19, and at the end of the control on the display panel 11 the malfunction lamp does not light up, which corresponds to the absence of failures of register-registers 2 and 3 and the complete erasure of information in memory block 9.

Claims (1)

Using the contact selection block 15, when the control unit 1 removes the distinctive features from the outputs of the register-counters 2 and 3, one can give distinctive signs on any two inputs of the analysis block 8, which are logically equivalent to the inputs connected to the counter-registers 2 and 3. When controlling the installation By fire on the indicator board 11 of the presence of a connection, it is possible to determine the presence or absence of a connection between the selected pins of the monitored connectors. In addition, if these connectors are disconnected from the device, you can connect any two pins of the output 19 and input 20 connectors of the device and check the correctness of the output for indication and printing of the established connection either in the control mode of the unit or in the control mode of the cable installation.
