Description

The wire size pick-up unit of 20 core plug sockets

Technical field

The utility model belongs to the line maintenance technical field, relates generally to a kind of wire size pick-up unit of 20 core plug sockets.

Background technology

In the operation circuit maintenance, a most important procedure detects wire size exactly.Because the length of a branch of pilot is long and be coiled in mutually together, therefore, an end of the line that is difficult to distinguish one from the other and which point of plug, socket are corresponding.

At present, the method that operating personnel adopt is by simple examination lamp device distinguish one from the other an end and corresponding of plug, socket of line, testing process is: at first, make a simple examination lamp device, examination lamp device is made up of discarded pilot lamp, two section leads on two joint dry cells, the locomotive; Wherein, an end of every section lead all is suppressed with contact pin, and on the some position of examination lamp device two section lead end attachment plugs or socket, another section lead end connects loose wire one end, and lamp is luminous just to prove that wire size is correct if try, otherwise wire size is just incorrect.

The simple examination lamp device that operating personnel adopted has the characteristics of simple and flexible, but also has following drawback:

(1) above-mentioned examination lamp device often needs two operating personnel's complete operations, and operating personnel are used for fixing plug and socket at plug and socket one end, and another operating personnel constantly put loose wire at the loose wire end, and put wire size.When the 3rd operating personnel go the operation of a some loose wire,, cause the duplicate detection single line owing to do not know it is the corresponding corresponding point of any root line position; If a point of every detection position, 20 lines all will be put examination one by one, increase the time of detecting greatly.

(2) above-mentioned examination lamp device is if people operation, and method of operating is: if test plug, then be that the lock pin with above-mentioned examination lamp device one end is inserted on certain some position of plug, so just fixed an end, save operating personnel, then, go the end operation of a loose wire again; If test socket then is inserted on the socket with contact pin, but in this case, loose wire end and plug or socket need be put together, need before the operation with circuit dish row neatly be convenient to one man operation; But, inconsistent when the model of the contact pin of the model of the contact pin of examination lamp device or lock pin and plug, socket or lock pin, make troubles to steady job, need operating personnel to note extraordinarily at this moment, more increased labor intensity of operating personnel.

Summary of the invention

The purpose of this utility model is the wire size pick-up unit that proposes a kind of 20 core plug sockets, makes it can reduce labor intensity of operating personnel, improves detection efficiency.

The utility model is finished the technical scheme that its invention task taked:

A kind of wire size pick-up unit of 20 core plug sockets, operation circuit one end of required detection wire size is 20 core plugs or socket, the other end is 20 leads; Detect promptly the corresponding light emitting diode that 20 tape labels are set of 20 leads to its numbering identification with need, 20 light emitting diodes are arranged on the housing and pass through bolt; Be provided with in the wire size pick-up unit and 20 core socket or the plugs that need to detect operation circuit one end, 20 core plugs or socket coupling, 20 leads of described 20 core sockets or plug link to each other with the negative pole of one of them light emitting diode respectively, and on 20 leads the mark with the identical label of corresponding diode; The positive pole of each light emitting diode links to each other with the positive pole of direct supply; The negative pole of described direct supply is connected with a lead and is connected with to detect at an end of lead uses contact pin.

Described wire size pick-up unit is two groups, and the light emitting diode of two groups of wire size pick-up units adopts different colors.

The wire size pick-up unit of a kind of 20 core plug sockets that the utility model proposes can reduce labor intensity of operating personnel during detection, can carry out single simultaneously or two people operation, has improved detection efficiency.

Among the figure: 1, housing, 2, bolt, 3, light emitting diode, 4,20 core sockets, 5, direct supply, 6, lead, 7,20 core plugs.

Embodiment

With embodiment the utility model is further specified in conjunction with the accompanying drawings:

As shown in Figure 1, a kind of wire size pick-up unit of 20 core plug sockets, operation circuit one end of required detection wire size is 20 core plugs 7, the other end is 20 leads; Detecting corresponding 3,20 light emitting diodes 3 of light emitting diode that 20 tape labels are set of 20 leads of promptly its numbering being discerned with need is arranged on the housing 1 also fixing by bolt 2; Be provided with in the wire size pick-up unit and the 20 core sockets 4 that need to detect operation circuit one end 20 core plugs 7 couplings, 20 leads of described 20 core sockets 4 link to each other with the negative pole of one of them light emitting diode respectively, and on 20 leads the mark with the identical label of corresponding diode; The positive pole of each light emitting diode links to each other with the positive pole of direct supply 5; Described direct supply 5 adopts two joint 1.5V dry cells; The negative pole of described direct supply 5 is connected with a lead 6 and is connected with to detect at an end of lead uses contact pin.During detection, use the contact pin that is communicated with dc power cathode to click 20 leads that are connected with 20 core plugs 7 respectively, certain root lead in the main points, pairing light emitting diode is just bright, and the label of respective leds puts corresponding label to this root line then.

Fig. 2 provides the structural representation of embodiment 2, and the wire size pick-up unit described in this embodiment is two groups, and the agent structure of every group of wire size pick-up unit is with embodiment 1; The light emitting diode of two groups of wire size pick-up units adopts different colors, can operate the detection of finishing two detection lines by two people simultaneously.During detection, each testing staff holds the wherein contact pin of a set detecting device, clicks 20 leads that this group is connected with 20 core plugs or socket respectively, and the color difference of every group of light emitting diode is convenient to testing staff's identification.
