Description

Coiling disc type overlength p-wire

Technical field

The utility model belongs to electric measurement, Power System and its Automation field, particularly relates to a kind of coiling disc type overlength p-wire.

Background technology

Existing p-wire group generally adopts many, ready-made, proprietary, special single core p-wire, parallel arranged, suitable distance and position is fixed with thermal shrinkable sleeve etc., be particular about the p-wire group of a bit, its outside is surrounded by flat insulating cover, the whole similar flat cable of p-wire, existing p-wire has following shortcoming: when using shorter p-wire group, when testing farther equipment, just testing tool need be moved, and testing tool is heavier or more sometimes, move testing tool very inconvenient, this can make troubles to test job, if and use longer p-wire group, although some p-wire group outside is surrounded by flat insulation sleeve, but due to the protection insufficient strength of its crust, when placing on the ground, easily should be subject to various physical disturbance (as people tramples) and damage, simultaneously because line is oversize, easily played by people, thus may test plug be pullled, the words that power of pullling is large also can damage test plug and socket, in addition, some longer p-wire group, though have the disc cassette of a similar tape measure to receive it, but its structure and size have been doomed, and it can not be received very long p-wire and (can not receive very long p-wire, its most important reason is in storage process, the inwall of p-wire crust and disc cassette produces sliding friction, because the flat crust of p-wire group adopts rubber like material, during the interior wall friction of itself and disc cassette, very large friction force can be produced, p-wire is longer, the friction force produced is larger, this just hinders the storage of p-wire further), generally can not more than 15 meters, and storage is extremely required great effort.As notification number: CN 102866270 A, " test wire for electrical test ", the test wire for electrical test of this patent adopts disc cassette storage p-wire, the p-wire of storage is shorter, storage effort, if pull p-wire because of carelessness when using this p-wire, the joint of p-wire may will come off, and even may damage joint and socket.

Summary of the invention

The utility model need move testing tool for prior art short-and-medium p-wire measurement equipment far away, long p-wire receives inconvenience, joint holds flimsy drawback; a kind of coiling disc type overlength p-wire is provided; have employed prolongation cable and can test equipment far away; extend cable drum outside wire spool; solve the problem of p-wire storage length; at prolongation cable, one end of banana plug is provided with magnet simultaneously, banana plug during test, can be protected not pullled to.

Goal of the invention of the present utility model is achieved through the following technical solutions:

A kind of coiling disc type overlength p-wire, comprise bracing frame, wire spool and p-wire, wire spool is connected on bracing frame by rotating shaft, the side panel face of wire spool is provided with banana bin, one end connecting test line of banana bin, the other end of banana bin is connected with prolongation cable, extends cable drum around on wire spool, the outer end extending cable is connected with banana plug A, extends on cable and is also provided with for locating the magnetic patch extending cable.Described p-wire two ends are all provided with banana plug B.

As preferably, described magnetic patch is near the outer end, the distance banana plug A50 ~ 100cm that extend cable.

When testing remote equipment, the banana plug B of p-wire one end inserts on the banana bin on the side panel face of wire spool, the banana plug of the p-wire other end inserts testing tool, the one end pulling prolongation cable to be provided with banana plug A just can launch to extend cable, thus can to testing equipment at a distance, when banana plug A is inserted equipment, the magnetic patch extended on cable can be adsorbed on irony fixture place on Devices to test or neighbouring, for preventing or reducing the possibility of pulling out banana plug A just in testing because of unexpected External Force Acting.When testing near field communication devices, only p-wire need be adopted to test.

The wire spool adopted has following features: relatively do not move between each element of its rotating part, and rotating part is integrally contacted with the stationary part of wire spool by two middle circular holes.When folding and unfolding extends cable, there is not sliding friction between rotating part and prolongation cable, friction force is very little, thus can around very long prolongation cable on wire spool, such as 50 meters, 100 meters.Be the sliding friction that surface of contact is very little between rotating part and rotating shaft, if be necessary, can also bearing be installed additional.Because surface of contact is little, so friction force is also very little comparatively speaking.

As preferably, the side panel face of wire spool is provided with the cable-clamping device for fixing prolongation cable.

As preferably, described cable-clamping device is U-shaped spring chuck.

As preferably, described U-shaped spring chuck is binder clip.The setting of binder clip is for the root of banana plug A being fixed on wire spool after prolongation cable housing is good, makes it moving and vertically to fall down not with wire spool.

As preferably, wire spool side panel face is provided with turning handle.When receiving prolongation cable, need to rotate wire spool, and the setting of turning handle, make rotation wire spool more convenient.

As preferably, described prolongation cable is RVV soft rubber cable, RVV soft rubber cable comprises some cable cores, cable core adopts some strands of soft copper silks to be entwined, soft rubber insulation course A is all coated with outside each root cable core, be provided with braid outside cable core, be provided with talcum powder layer outside organization level, talcum bisque peripheral hardware has soft rubber insulation course B.The setting of braid improves the tensile strength extending cable, adopts soft copper silk as the setting of cable core and soft rubber insulation course A and soft rubber insulation course B, makes to extend whole cable softer, is applicable to wire spool storage.

As preferably, the quantity of cable core, banana bin and banana plug A three is equal.Each root cable core two ends is all connected to a banana bin and a banana plug A.

Compared with prior art, the utility model has following beneficial effect: use the utility model, when needs test remote equipment, without the need to moving testing tool, as long as pull-out extends cable one end with banana plug A to equipment under test.Arranging of wire spool can make the prolongation cable of storage more lengthen, and can test farther equipment, and the resistance of wire spool is little, and the folding and unfolding extending cable becomes simple, laborsaving.Because employ RVV soft rubber cable as prolongation cable, the ability that the part resistance to mechanical that prolongation cable is placed on ground is destroyed is stronger.The use of binder clip, makes test the end of a thread to be fixed on wire spool easily, can not fall down carelessly along with moving of wire spool.The use of magnet, makes in test process, greatly reduces the possibility of pulling out banana plug A just in testing because of unexpected External Force Acting, and from an another angle, the socket also protected on the banana plug A of test and equipment is not destroyed.
