The checking tool for the connection of the multicore flat cables, provided by the utility model, has the advantages of simple structure, portability, simple detecting operation, capability of detecting if the multicore flat cables before being used are perfectly connected, capability of ensuring the correct connection of the flat cables and the socket terminals, and convenience in use.
Description
Technical field
The utility model belongs to electronic circuit field, is specifically related to a kind of multicore winding displacement and connects checking tool.
Background technology
In electronic circuit, the use of multicore winding displacement is very extensively tested the very necessary of change to the multicore winding displacement accurately and rapidly.
In the use of winding displacement, there is not special testing tool at present.Because multicore winding displacement jointing structure is more airtight, in case the connection of used winding displacement goes wrong, detect the comparison difficulty, and because operation inconvenience, testing result might not be accurate.Common one group of winding displacement comprises the multicore fine rule, and one one test is relatively lost time.
The utility model content
The purpose of the utility model provides a kind of multicore winding displacement and connects checking tool, to solve the existing unhandy problem of detection method.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of multicore winding displacement connects checking tool; The gang socket of multicore winding displacement and power supply branch road and one group of light indication branch road of comprising a pair of multicore winding displacement two-terminal to be measured that is used to peg graft; Said power supply props up the route power supply and a CS composes in series; The quantity of said light indication branch road identical with the contact element number of one of them multicore winding displacement gang socket and with its corresponding connection; The other end of each light indication branch road links together and links to each other with an end of power supply branch road, and each contact element of another multicore winding displacement gang socket interconnects and links to each other with the other end of power supply branch road.
Said each light indication branch road is composed in series by a LED light and a current-limiting resistance respectively.
The gang socket of said multicore winding displacement, power supply, CS and LED light and current-limiting resistance are located on the wiring board, connect through the printed board line.
The gang socket of said multicore winding displacement is 40 pins, 20 pins, 16 pins, 14 pins or 10 needle sockets.
The multicore winding displacement of the utility model connects checking tool and forms an open loop circuit by a pair of multicore gang socket, power supply, CS and LED light; Form closed loop after connecting winding displacement; Through the LED indication on the indication testing tool, it is intact to judge accurately, fast whether the multicore winding displacement all connects.Whether this tool construction is simple, and is easy to carry, and detecting operation is simple, can detect winding displacement and connect intactly before use, guarantees that the connection of winding displacement and female terminal is errorless, convenient to use.
Description of drawings
Fig. 1 is the schematic diagram that the utility model multicore winding displacement connects checking tool.
Embodiment
Be illustrated in figure 1 as the schematic diagram that the utility model multicore winding displacement connects checking tool; Can know by figure; This instrument comprises the gang socket of multicore winding displacement and power supply branch road and one group of light indication branch road of a pair of multicore winding displacement two-terminal to be measured that is used to peg graft; Said power supply props up the route power supply and a CS composes in series; The quantity of light indication branch road identical with the contact element number of one of them multicore winding displacement gang socket and with its corresponding connection; The other end of each light indication branch road links together and links to each other with an end of power supply branch road, and each contact element of another multicore winding displacement gang socket interconnects and links to each other with the other end of power supply branch road.Each light indication branch road is composed in series by a LED light and a current-limiting resistance respectively.
The gang socket of multicore winding displacement, power supply, CS and the LED light of present embodiment and current-limiting resistance constitute an open loop circuit; Be located on the wiring board; Connect through the printed board line; With the winding displacement that will test form a current return, through the luminous quality of indicating winding displacement of LED.
Above-mentioned this gang socket comprises models such as 40 pins, 20 pins, 16 pins, 14 pins and 10 pins respectively to the multicore winding displacement, more than the plug of various models all occur with paired form: one of them be A-n, and another is B-n, and n is the type figure of correspondence.In the present embodiment, A-n is connected with the LED lamp anode, the corresponding LED lamp of each pin line, and B-n is connected with said detection CS K.CS one end is connected with the B-n of said multicore winding displacement gang socket, and the other end is connected with the anode of power supply P, CS K control loop current switching; The negative electrode of power supply P is connected with current-limiting resistance R1～Rn; Current-limiting resistance one end is connected with power cathode; The negative electrode of the corresponding LED light L1 with each of the other end～Ln connects, and current-limiting resistance carries out current limliting to the loop after being mainly used in the loop conducting, and power supply is that the loop provides voltage.
In the present embodiment, LED light can be selected 40 for use, and the pin of the winding displacement gang socket of different model is connected with the negative electrode of the LED light of reference numeral respectively.
In Fig. 1, Ln can be respectively L40, L20, L16, L14, reach L10, and the socket of corresponding different number of pin connects, and this testing tool can be tested the winding displacement of 40 cores, 20 cores, 16 cores, 14 cores and 10 heart yearns respectively.
After connecting winding displacement, the whole open loop of multicore winding displacement connection checking tool forms closed loop circuit; During test; Be inserted into multicore winding displacement to be measured two ends respectively in the multicore winding displacement gang socket of corresponding line number the CS that closes, circuit turn-on; If the LED light of corresponding pin numbering is bright entirely, then this winding displacement is normal; If there is the LED light of corresponding pin numbering not work, then this multicore winding displacement connects the correspondence position poor flow.
The utility model can adopt multi-form multicore winding displacement gang socket according to the difference of multicore winding displacement joint form, can adapt to different core numbers, and the multicore winding displacement of different joint forms connects.
