Preferably, the insulation sleeve is flexible rubber insulation sleeve, and electricity is fixed in one end of the rubber insulation sleeve
Pole root, when no pressure acts on, the length of the rubber insulation sleeve is more than the length of electrode column.
Further, when no pressure acts on, there are gaps between the rubber insulation sleeve and electrode column.Since rubber is exhausted
There are gaps between edge set and electrode column, then when being inserted into electrode column, the frictional force very little between rubber insulation sleeve and electrode column,
Electrode column can be easily inserted in jack.After electrode column is extracted from jack, due to rubbing between rubber insulation sleeve and electrode column
It is smaller to wipe power, so that rubber insulation sleeve is more successfully resetted rapidly, and then wrap up electrode column again.
Further, the spring for being used to help rubber insulation sleeve rebound is provided on the inside of the rubber insulation sleeve.Pass through
The spring is set, rubber insulation sleeve can be helped more quickly to spring back, when experiment operator extracts electrode column from jack
When, the rubber insulation sleeve of moment rebound wraps up electrode column, more support personnel's safety.
Second of the utility model is designed to provide a kind of Experiments of Electricity conducting wire, by the Experiments of Electricity conducting wire application
In electrophysics experiment, the security risk of wire short-circuiting can be eliminated, ensures experiment and the safety of personnel.
To achieve the goals above, the utility model provides following technical scheme.A kind of Experiments of Electricity conducting wire, feature exist
In, including conducting line segment and two plugs at conducting line segment both ends are set, the plug is any description above plug.
Compared with prior art, the utility model is around electrode column by being arranged insulation sleeve, when being intended to the electrode column
When being inserted into jack, jack edge forms pressure to insulation sleeve, and insulation sleeve is made to retreat, and the electrode column of exposing is inserted into jack, and with
Connecting terminal contact conducting in jack.After extracting the electrode column, jack edge disappears to the pressure of insulation sleeve, and insulation sleeve is multiple
Simultaneously wrap up electrode column in position.So even if electrode column in the case where charging and being not inserted into jack, due to there are the protection of insulation sleeve,
It will not cause short circuit.
The plug is also applied to Experiments of Electricity conducting wire by the utility model, by the Experiments of Electricity conducting wire including the plug
In being tested applied to electrophysics, it is not easy short circuit safely, can ensure experiment and the safety of personnel.

Specific implementation mode
Below in conjunction with attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu completely describes.It should be appreciated that specific embodiment described herein is used only for explaining the utility model, it is not used to limit
Determine the utility model.Based on the embodiments of the present invention, those skilled in the art are in no creative work under the premise of institute
The every other embodiment obtained, belongs to the scope of protection of the utility model.
Embodiment 1：
It please refers to Fig.1 to Fig.4, present embodiments provides a kind of plug, the plug includes electrode column 10, the electrode column
10 be cylindrical-shaped structure or cuboid piece column structure (but not limited to this).It is provided with and is used for around the electrode column 10
Wrap up the insulation sleeve of the electrode column 10.The insulation sleeve retreats under pressure makes electrode column 10 expose, after pressure disappears
The insulation sleeve resets and wraps up electrode column 10.
In use, when being intended to the electrode column 10 being inserted into jack, jack edge forms pressure to insulation sleeve, makes insulation sleeve
It retreats, the electrode column 10 of exposing is inserted into jack, and contacts conducting with the connecting terminal in jack.Extract the electrode column 10
Afterwards, jack edge disappears to the pressure of insulation sleeve, and insulation sleeve resets and wraps up electrode column 10.So even if electrode column 10 is charging
And in the case of being not inserted into jack, since there are the protections of insulation sleeve, short circuit will not be caused.

It is easily inserted in jack.After electrode column 10 is extracted from jack, due to the friction between rubber insulation sleeve 20 and electrode column 10
Power is smaller, so that rubber insulation sleeve 20 is more successfully resetted rapidly, and then wrap up electrode column 10 again.
In order to further increase the rebound velocity of the rubber insulation sleeve 20, the safety of the plug is improved, in this reality
It applies in example, can the spring 30 for being used to help rubber insulation sleeve 20 and springing back be set in the inside of the rubber insulation sleeve 20.In order to
It avoids screen resilience from crossing ambassador's electrode column 10 to loosen from jack, the spring 30 selects the lower spring of coefficient of elasticity, the bullet
Spring 30 can be pasted onto the inside of the rubber insulation sleeve 20 using adhesive.By the way that the spring 30 is arranged, as experimental implementation people
When member extracts electrode column 10 from jack, the rubber insulation sleeve 20 of moment rebound wraps up electrode column, more support personnel's safety.
Fig. 3 and Fig. 4 are please referred to, in the present embodiment, the plug is also provided with for hand-held insulation shell 40, is made
To illustrate, the insulation shell 40 is cylindrical structure.The electrode column 10 is set to the front end of the insulation shell 40, and with insulation
Electric wire connection inside shell 40.The rear end of the insulation shell 40 is provided with the circular hole 50 for being inserted into for other plug electrode columns,
After other plug electrode columns are inserted into circular hole 50, other plug electrode columns are connected with the electric wire in this plug insulation shell 40.
The plug is applied to Experiments of Electricity conducting wire, the plug is arranged in the both ends of Experiments of Electricity conducting wire, when the spacing of experimental facilities
From farther out and when the curtailment of solid conductor, several Experiments of Electricity conducting wires head and the tail can be connected, experiment can not only be met
It needs, and safety is not easy short circuit.
