Abstract

The utility model relates to a number detecting device for separating wires of a cable core, and is composed of a wire clamping terminal, a light emitting diode, a buzzer, a finding pen, etc. The utility model is especially suitable for the detecting number of the separating wires of the middle of a local phone cable. The utility model has the advantages of simple structure, convenient use, work program reducing, work efficiency improvement, etc., and is an ideal number detecting device for the separating wires of a cable core.

Description

Detecting device for separating wires of cable core

The utility model is a kind of instrument that the cable core separated time is checked the number that is used for.

When punishing line in the middle of the local cable, check mark is a pretty troublesome job.Heart yearn often will be done branch's (or cry roll off the production line) at the cable more than 100 pairs on interlude.After the quantity of separated time, line preface are determined, will press a pair of line of line preface elder generation's short circuit at the top of cable (distributing frame); Or a pair of heart yearn ground connection; Or on a pair of heart yearn, put buzz, and break cable cover(ing) at the cable branch place, scratch the insulation course of heart yearn with blade, test loop resistance with avometer; Or survey stake resistance; Or listen buzz, find out this to line.Like this cumbersome to line (hunting) mode working routine, the working time is long owing to destroyed the core insulation layer, lead sustains damage easily.

The purpose of this utility model is that proposition is a kind of simple in structure, easy to use, reduces working routine, increases work efficiency, and is adapted to the buzzerphone of the middle separated time of local cable especially.

The utility model is made up of two parts, and signal takes place, showing, converse holding high office is a part, and hunting pen, monophone are another part.The purpose of this utility model is achieved in that a plurality of card line terminals respectively through connecting together behind a plurality of light emitting diodes, and through buzzer circuit, the speech circuit utmost point to power supply, the draw point of another utmost point of power supply in a lead and hunting pen joins again.One pushing ram is arranged in the hunting pen is latter half of, the front end of pushing ram is a draw point, and draw point can stretch out in the front end pore of hunting pen, and the draw point of first half is outer round a back-moving spring in the hunting pen, the hunting anterior end of pen has an aperture, and aperture is other to have a heart yearn that matches with draw point to link up with.

The utility model circuit is simple, and is multiple functional, easy to use, and buzzing, demonstration are accurately, and be simple in the middle separated time place's hunting of cable, rapidly.

Provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is buzzerphone circuit, one-piece construction, user mode figure.

Fig. 2 is a hunting structural drawing.

Wherein: 1-card line terminals 2-luminotron 3-hummer

A 4-speech device 5-hunting 6-pushing ram

7-draw point 8-spring 9-heart yearn hook

Card line terminals shown in the figure is 60, can do 20～200 during actual fabrication, and is perhaps more, and the quantity of light emitting diode is identical with the quantity of card line terminals.The card line terminals can be used fish mouth folder, and power supply is 6V, and it is promptly carefully hard again that the draw point in the hunting pen will be done, and hooks heart yearn with heart yearn during use, promotes pushing ram, makes draw point thrust heart yearn and lead connection.

Principle of work and using method are:

One, checks the number: at top the heart yearn that will tell is connected on the card line end of buzzerphone, carries out hunting with the hunting pen at the cable branch place.After seeking the line that should tell, circuit is connected.Power supply "+" → potentiometer (W) → three-point switch (K) → hummer → luminotron → fish mouth folder → cable core → hunting pen → monophone → electrical cable aluminium sheath (moulding the cable screen layer), or ground connection → power supply "-".Hummer work playback this moment, the top of cable, separated time place receiver are all heard musical sound, luminotron shows that this line is to logical simultaneously.

Two conversations: heart yearn needs conversation to after logical, and the three-point switch of buzzerphone pushes communicating end, and the hummer outage stops playback, and both sides can converse.

Three huntings: the hook at the separated time place with the hunting pen tangles heart yearn, and the pushing ram of pressing behind the tail is released the draw point in the pen, punctures core insulation layer and lead and joins, and makes the circuit connection, and both sides hear musical sound.

Claims

1, a kind of cable core separated time buzzerphone, it is characterized in that: 20～200 card line terminals, respectively through connecting together behind 20～200 light emitting diodes, through buzzer circuit, the speech circuit utmost point to power supply, the interior draw point of another utmost point of power supply and hunting pen joins again.

2, cable core separated time buzzerphone according to claim 1, it is characterized in that: a pushing ram is arranged in the hunting pen is latter half of, the front end of pushing ram is a draw point, the draw point of first half is outer round a back-moving spring in the hunting pen, the front end of hunting pen has an aperture, and aperture is other to have a heart yearn that matches with draw point to link up with.
