Abstract
The utility model discloses a special plug used for connecting a temporary power supply, comprising two alligator clips provided with insulating shells, two insulating fixing bases, and cylindrical power supply double pins, wherein the two pins are respectively arranged on the two insulating fixing bases, side surfaces of the two pins are provided with arc-shaped conductive spring strips which are contacted with the pins, a splicing device which is convenient for disconnecting and connecting the two insulating fixing bases is provided between the two insulating fixing bases, and the pins are either fixedly connected with leads or detachably connected with the leads. The special plug of the utility model has the advantages that: the combination and the separation between the two pins of the plug can be selected freely according to the type of the connecting power supply at the testing site; the special plug can be connected with the power supply flexibly and conveniently either in a live way or a power failure way, thus the special plug has the advantages of safety and reliability; when a power line is not long enough, the special plug and the power supply also can be buttedly connected conveniently; and the special plug also can avoid trivial things caused by changing the power plug temporarily, thus the special plug of the utility model has flexible applications, and can raise working reliability and working efficiency of safety production.
Description
Technical field
The utility model relates to a kind of plug special, particularly a kind ofly accesses interim power supply plug special.
Background technology
Usually the work about electric power personnel are carrying out in the high voltage test process high voltage electric equipment, and the test apparatus of the overwhelming majority is the AC power that needs external 220V, before test, will access experiment power supply earlier.Because experiment work is on-the-spot different, have in the city and the field, have in transformer station, the type that accesses power supply point is also different, has plenty of supply socket, has plenty of distribution box, also has plenty of special-purpose maintenance power supply box.When particularly on charged distribution box, accessing experiment power supply; Need double plug be removed; Be wrapped in power line then and access power supply on the clip, exist the habituation of arbitrarily twining overlap joint violating the regulations, the personnel that cause easily get an electric shock or unsafe factor such as phase fault; Power supply accesses also very inconvenience simultaneously, and operating efficiency is low.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of being useful in to access on the types such as maintenance power supply box, distribution box and supply socket, can chargedly access the plug special of interim trial power supply again.
A kind ofly access interim power supply plug special; Its structural feature is: comprise two crocodile clips that have insulation shell, two insulation holders, the two pins of columniform power supply; Two pins are arranged at respectively on the two insulation holders; Also be provided with the conduction spring with the contacted arc of pin in the side of two pins, be provided with the convenient splicing apparatus that two insulation holders are taken apart and connected between two insulation holders, described pin or be connected with lead fixed; Or removably connect with the lead activity, an end of crocodile clip is provided with the hole that can insert cylindrical pin.
In use,, can two insulation holders of two pins be combined, be equivalent to a common attaching plug if the working site accesses power supply point when being socket; If it is the maintenance power supply box that the working site accesses power supply point, can two insulation holders of two pins be taken apart, only get wherein a pin and directly be connected on sky and open the below; If the working site accesses power supply point when being charged distribution box, can two insulation holders of two pins be taken apart, only get a wherein pin, the crocodile clip of tape insulation is inserted pin, utilize the crocodile clip of tape insulation to access power supply.Be provided with the steel shape spring of arc in the side of cylindrical pin, can make cylindrical pin and crocodile clip make it fastening when inserting.
Described conduction spring is the rigidity spring.
The other end of described lead links to each other with socket.
Stiff end at two pins also is provided with the axially extended blind hole along pin.
Stiff end at two pins is provided with the axially extended blind hole along pin, can supply same attaching plug to dock with it easily, to access interim power supply.
Splicing apparatus between the described two insulation holders is for being connected through T type groove.
Described two insulation holders are that light-duty insulating material constitutes.
Described cylindrical pin, its material is a steel material.
In sum, the utility model is compared the following advantage of prior art:
This power supply two pins can make up and fractionation, can access the power supply point type according to the testing ground and carry out freely selecting, and live conveniently no matter charged still power failure accesses Turin, and are safe and reliable.When power line falls short of, can dock easily.Also avoided cumbersome thing, embodied this attaching plug flexible Application, improved safety in production reliability and operating efficiency because of the Iterim Change attaching plug.Mentality of designing has novelty, and practicality is good, availability is strong; Input cost is low, and application prospect is extensive.This power supply two plugs can also be promoted the plug that accesses the construction power supply in the other industry job site.

Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind ofly shown in Fig. 1-8, access interim power supply plug special; Comprise two 1, two insulation holders 2 of crocodile clip that have insulation shell, the two pins 3 of columniform power supply; Two pins are arranged at respectively on the two insulation holders; Also be provided with in the side of two pins and be provided with the convenient splicing apparatus 21 that two insulation holders are taken apart and connected between 4, two the insulation holders of rigidity spring with the contacted arc of pin, described pin is fixedly connected with lead 5.The other end of lead links to each other with socket.Stiff end at two pins also is provided with the axially extended blind hole 31 along pin.One end of crocodile clip is provided with the hole 11 that can insert cylindrical pin.Splicing apparatus between the described two insulation holders is for being connected through T type groove.Described two insulation holders are that light-duty insulating material constitutes.Described cylindrical pin, its material is a steel material.
It is identical with prior art that present embodiment is not stated part.
