Abstract
The utility model discloses a conductive connecting device of a gas-insulated metal closed switchgear. The conductive connecting device comprises a conductive riser, a contact pedestal, a spring sensing finger, a guide rod, a conductive rod and an insulated guide ring, wherein the inner hole of the contact pedestal is provided with more than one annular groove; the spring sensing finger is arranged in the annular groove; the conductive rod and the inner hole of the contact pedestal are connected by the spring sensing finger in a transition way. After the conductive rod is inserted into the inner hole of the contact pedestal, as the size of the outer diameter of the conductive rod is larger than the size of the inner diameter of the spring sensing finger, the inclined angle of the spring sensing finger can be increased; moreover, the increased inclined angle can be used to generate elasticity, so as to maintain the contact pressure and stabilize through flow; as the deformation of the inclined angle of the spring sensing finger generates elasticity and obtains contact pressure, the spring sensing finger can obtain larger deformation amount; and a larger clearance is employed to match the location precision. In addition, parts are easy to be manufactured and assembled; meanwhile, the structure can be simplified, the design can be optimized and the cost can be reduced.
Description
Technical field:
The utility model relates to a kind of Cubicle Gas-Insulated Switchgear conductive connecting device.
Background technology:
Known Cubicle Gas-Insulated Switchgear conduction connects employing Mume flower contact, watchband fingertip or spring touch finger radial compression structure, the Mume flower contact part is more, complex structure, overall dimension are big, be difficult for simplified structure, dwindle overall dimension, and contact point is few, contact stabilization is poor, is difficult to big capacity extension; The watchband fingertip effectively simplified structure, dwindle overall dimension, but require that fit clearance is little, part processing precision is high, assembling is difficult, especially when big capacity, because the increase of fingertip quantity, frictional force, damage conductive contact surfaces be will increase, conductive stability and kinematic dexterity influenced; Spring touch finger radial compression structure needs to keep in touch pressure in the little distortion of radially generation of spring, and quality of fit height, frictional force are big, and spring touch finger easily lost efficacy.
The utility model content:
The purpose of this utility model provides the steady in a long-term through-flow Cubicle Gas-Insulated Switchgear conductive connecting device of a kind of energy.
The utility model is realized its purpose by following technical scheme:
The Cubicle Gas-Insulated Switchgear conductive connecting device, comprise conduction transition block, contact base, spring touch finger, guide post, conducting rod and insulation guide ring, it is characterized in that: one and above annular groove are set on the endoporus of contact base, spring touch finger is loaded in the annular groove, and conducting rod is connected by the spring touch finger transition with the contact base endoporus.After conducting rod inserts the contact base endoporus,, realize the maintenance of contact pressure and stablize through-flow because the conducting rod outside dimension greater than the spring touch finger internal diameter size, will increase the angle of inclination of spring touch finger, and utilizes the angle of inclination that increases to produce elasticity.
Annular groove bottom shape in the described contact base is a V-arrangement, and the bottom portion of groove angle is 125 °～135 °, and recess width is 12～12.2mm.
The spring wire diameter of described spring touch finger is 1.2～1.5mm, and the ring spring diameter of spring touch finger is 11.7mm, bilateral decrement 3～3.5mm, and the angle of inclination is 45 °～60 °.
To the conductive connecting device of static connection, adopt the guide post location, location fit clearance 1～1.5mm; To the conductive connecting device that axially is dynamically connected, adopt insulation guide ring location, location fit clearance 0.2～0.5mm.
According to the difference of the specified current capacity of product, corresponding spring touch finger quantity is set.
After the Cubicle Gas-Insulated Switchgear conductive connecting device that the utility model provides adopts above-mentioned conductive connecting device, conduction overlapping part to static connection, pack into behind the conducting rod, utilize the endoporus location of guide post and conducting rod, realize the internal diameter centering location of conducting rod and spring touch finger, and make the spring touch finger compression angle that tilts produce strain, it is through-flow to keep in touch pressure stability; Obtain contact pressure owing to utilize the angle of inclination distortion of spring touch finger to produce elasticity, the desirable bigger deflection of spring touch finger, positioning accuracy cooperate is adopted bigger gap, the easy processing and fabricating of part, assembling easily, but simultaneously simplified structure, optimal design, reduce cost.To the conduction overlapping part that axially is dynamically connected, behind the conducting rod of packing into, utilize insulation guide ring internal diameter and conducting rod external diameter centering location, and make the spring touch finger compression angle generation strain that tilts, it is through-flow to keep in touch pressure stability.
