Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
- Fig. 4 referring to fig. 2 shows a kind of 4 voltage-withstand test connector of switchgear of one preferred embodiment of the utility model,
It further include cannulated sleeve 2 including conductor 1, conductor 1 is installed in cannulated sleeve 2, and can be rotated relative to cannulated sleeve 2
Movement, one end of conductor 1 are used to connect extraneous switchgear 4, and the other end is used to connect extraneous test wire 6.In use, first will
One end of 4 voltage-withstand test connector of this switchgear is fixedly attached on the high-pressure resin insulating sleeve 7 of extraneous switchgear 4, so
Afterwards in the other end solderless wrapped connection test wire 6 of 4 voltage-withstand test connector of this switchgear, pressure test can be carried out.It is existing to solve
There is in technology the problem (referring to Fig. 1) for leading to clearance for insulation deficiency because of the attaching insulating sleeve of test wire 6, and then solves resistance to
The problems such as pressure test process middle sleeve climbs electricity, discharges shell.In addition, can be rotated relative to cannulated sleeve 2 fortune by conductor 1
Dynamic, i.e., conductor 1 can make spinning motion by rotation axis of own axes, thus when conductor 1 to be installed on switchgear 4, it can
To be rotated further by conductor 1, and conductor 1 is fixedly attached on switchgear 4, installation process letter by holding cannulated sleeve 2
Just quick, save labour.Wherein, conductor 1 can snap fit on the high-pressure resin insulating sleeve 7 of switchgear 4, for example, can be with
The snap fit of incandescent lamp Yu its lamp holder is copied, i.e., so that it is snapped fit onto the high-pressure resin insulation sleeve of switchgear 4 by rotating conductor 1
On pipe 7；In the present embodiment, one end that conductor 1 connect with extraneous switchgear 4 is equipped with screw thread 11, screw thread 11 suitable for
Extraneous switchgear 4 connects, and can be rotated relative to cannulated sleeve 2 by conductor 1, thus conductor 1 passes through its screw thread 11
It is fixedly attached on switchgear 4, the also more firm and saving set-up time.
Preferably, cannulated sleeve 2 is made of stainless steel material, due to the disconnected magnetic significant effect of stainless steel material, in reality
On the basis of existing conductor 1 is rotated relative to cannulated sleeve 2, it can reduce test process middle sleeve and climb electricity and to the general of shell electric discharge
Rate.
Further, the outer surface of cannulated sleeve 2 is socketed with Insulating heat shrink 3, to further increase this switchgear 4
The insulation effect of voltage-withstand test connector further decreases test process middle sleeve and climbs electricity and the probability to shell electric discharge.Compared with
Good, the inner wall of insulating sleeve is covered with layer of silica gel, and insulation silica gel can be further improved the insulating capacity of insulating sleeve.
In order to further decrease test process middle sleeve climb electricity and to shell electric discharge probability, the one of Insulating heat shrink 3
End has attachment cap 31, and attachment cap 31 is used to connect the high-pressure resin insulating sleeve 7 installed on extraneous switchgear 4.Also, by
In the fulcrum on the high-pressure resin insulating sleeve 7 that attachment cap 31 is socketed in switchgear 4, and as stress, more conducively this is switched
4 voltage-withstand test connector of cabinet is installed on the high-pressure resin insulating sleeve 7 of switchgear 4；It is appreciated that due to Insulating heat shrink
3 are socketed in the outer surface of cannulated sleeve 2, i.e., are difficult to relatively rotate between Insulating heat shrink 3 and cannulated sleeve 2, this is switched
When 4 voltage-withstand test connector of cabinet is installed on the high-pressure resin insulating sleeve 7 of switchgear 4, first attachment cap 31 can be put on
On the high-pressure resin insulating sleeve 7 of switchgear 4, a fulcrum force is formed, then by holding Insulating heat shrink 3,
Conductor 1 is rapidly rotated, and realizes docking for conductor 1 and the high-pressure resin insulating sleeve 7 of switchgear 4, installation process is simpler
Just quick.
It, can be with preferably, one end of conductor 1 and extraneous test wire 6 is formed with boss 12 along the axial projection of conductor 1
Convenient for installation tool is socketed on boss 12, thus by step as supporting point, manpower rotational installation tool of being more convenient for, with
Conductor 1 is installed to and is opened the light on cabinet；I.e. so that 4 voltage-withstand test connector of this switchgear install it is more simple and efficient.It is preferred that
Ground, boss 12 along its it is axially extending be formed with handle 13, handle 13 is vertically arranged with boss 12, and boss 12 and handle 13 form T
Type structure, handle 13 can be for extraneous 6 solderless wrapped connections of test wire.It is appreciated that by the way that boss 12 and handle 13 are formed T junction
Structure can directly rotate conductor 1 in order to manpower, so that further it is convenient for the installation of 4 voltage-withstand test connector of this switchgear, without
It must be assisted using installation tool, improve installation effectiveness.Moreover, T-type structure can be more conducive to the solderless wrapped connection of test wire 6, make
The firm solderless wrapped connection of test wire 6 is obtained on conductor 1.
In the present embodiment, conductor 1 is preferably made of copper material, and copper material conducts electricity very well, more conducively resistance to
Press the accuracy of test.
It what needs to be explained here is that conductor 1 can be integrally formed, seperated can also form, when integrated molding, can reduce
The manufacture difficulty of conductor 1.
The 4 voltage-withstand test connector of switchgear of the utility model, has the advantages that following significant:
1, solve the problems, such as that test wire 6 attaches Insulating heat shrink 3, so that pressure test process middle sleeve be avoided to climb
The phenomenon that electric, to shell electric discharge, so that pressure test can be normally carried out.
2,4 voltage-withstand test connector installation process of this switchgear is simple and efficient, reduces labor intensity.
3, it is suitable for the products such as power distribution cabinet, switchgear 4, it is versatile.
4, since conductor 1 has certain length, to effectively prevent the drawback of clearance for insulation deficiency.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
