Background technology
In the statics test of rocket type product, use in a large number 5 core cables to transmit signal between sensor and measuring junction, as conveying capacity sensor, displacement transducer signal etc.Signal transmission line road whether unobstructed directly has influence on the success of type product statics test, therefore, in statics testing regulations, specifies: before test, must check the various cable through that uses, open circuit and short-circuit conditions.
Because rocket model small product size one end large, 5 core cables has been fixed on some factors such as test factory building, the inspection work of 5 core cables is carried out in testing ground conventionally, and this just needs checking tool to have portability.Common inspection method is: multimeter is pushed to wire break-make gear, measure the break-make situation of certain root heart yearn in cable with test pencil, then take this method to check by heart yearn to cable.But this mode is slower, can not directly check out the short-circuit conditions between the each heart yearn of cable, in addition because the test pencil of multimeter is thicker, and the plug of the 5 core cables that use is less, and the contact spacing that each heart yearn is corresponding is narrow, and comparatively inconvenience operates when inspection.In the time that test is used 5 a large amount of core cables, check that workload is large, the work that only checks just consumes a large amount of time, and then has delayed the process of test.
Therefore, requiring has the instrument that a kind of portability is strong, can reduce supervision time, easy operating, intuitive display, carries out the inspection work of 5 core cables.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, provide a kind of and there is portability, can reduce the supervision time, 5 core cables through of easy operating, intuitive display, open circuit and test for short-circuit instrument, to check the state of cable according to testing regulations, reduce the time checking.
For achieving the above object, technical solution adopted in the utility model is: a kind of inspection 5 core cables through, open circuit and the portable instrument of short-circuit conditions, comprise light emitting diode group, internal battery charge port, the 5 core cable socket second groups compositions of contact button group 2,5 core cable socket first groups, instruction use; Wherein, 5 core cable socket first groups, 5 core cable socket second groups are corresponding two groups of socket groups that arrange, and all include the socket of the plug coupling of several and examine 5 core cables above; The core of each socket of 5 core cable socket first groups all connects the power supply in internal battery charge port through light emitting diode group; Accordingly, the core of each socket of 5 core cable socket second groups all connects another utmost point of power supply in internal battery charge port through contact button group, in 5 core cable socket first groups, 5 core cable socket second groups, the core of one group of corresponding socket connects the two ends of same 5 core cables.
Described 5 core cable socket first groups and 5 core cable socket second groups are symmetrical arranged up and down at portable instrument, the one side of the portable instrument between 5 core cable socket first groups, 5 core cable socket second groups is as guidance panel, and the button of corresponding contact button group and the pilot lamp of light emitting diode group are symmetrical arranged on guidance panel.
The utility model has the advantages that: (1) is used powered battery, has portability; (2) once check break-make and the short-circuit condition that only need touch successively 5 electric shock buttons and just can draw 5 core cables, easy operating and saving time; (3) use light emitting diode to indicate the on off operating mode of each heart yearn, intuitive display.At present, the utility model successfully uses in the statics test of rocket type product.
Brief description of the drawings
Fig. 1 is that routine profile schematic diagram is executed in this practicality;
Fig. 2 is the circuit theory diagrams that this practicality can be novel.
In figure, 1-5 core cable, 2-contact button group, 3-5 core cable socket first group, 4-light emitting diode group, 5-internal battery charge port, 6-5 core cable socket second group, A, B-contact.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Principle of the present utility model is: the part using 5 checked core cables as the circuit loop of design.In the time of cable root heart yearn path, press corresponding contact, circuit loop is working properly, only has corresponding light emitting diode bright; In the time that cable root heart yearn opens circuit, press corresponding contact, circuit loop work is undesired, and corresponding light emitting diode does not work; In the time of several short circuits between conductors of cable, press the wherein a certain contact that core is corresponding, the light emitting diode that these several cores of short circuit are corresponding is bright; Stagger the time when two heart yearns of cable order, press the wherein a certain contact that core is corresponding, the light emitting diode that the wrong core of order is corresponding is with it bright, and the light emitting diode of itself correspondence does not work.
According to above-mentioned principle, the utility model as shown in Figure 1, comprises that light emitting diode group 4, internal battery charge port 5, the 5 core cable socket second groups 6 of contact button group 2,5 core cable socket first groups 3, instruction use form; Wherein, 5 core cable socket first group 3,5 core cable socket second groups 6 are corresponding two groups of socket groups that arrange, and all include 3 sockets that mate with the plug of examine 5 core cables 1 above; The core of each socket of 5 core cable socket first groups 3 all connects the power supply in internal battery charge port 5 through light emitting diode group 4; Accordingly, the core of each socket of 5 core cable socket second groups 6 all connects another utmost point of internal battery charge port 5 interior power supplys through contact button group 2, in 5 core cable socket first group 3,5 core cable socket second groups 6, the core of one group of corresponding socket connects the two ends of same 5 core cables 1.
For ease of operation, 5 core cable socket first group 3,5 core cable socket second groups 6 are symmetrical arranged up and down at portable instrument, the one side of the portable instrument between 5 core cable socket first group 3,5 core cable socket second groups 6 is as guidance panel, and the button of corresponding contact button group 2 and the pilot lamp of light emitting diode group 4 are symmetrical arranged on guidance panel.
