Description
Technical field
The utility model relates to the connecting elements of power capacitor press insert type insulator binding post and tin-coated copper twisted wire, is specifically related on a kind of capacitor with press insert type insulator binding post and copper stranded conductor jockey.
Background technology
The variation that requires according to electric power with the connected mode of the copper tip of press insert type insulator and copper stranded conductor on the power capacitor; At present mainly by three kinds of structures: first kind of mode is that " Xi'an innovation energy project Co., Ltd " is in " wiring construction of a kind of high-voltage power capacitor unit outlet terminal " of 2010. 07. 09 applications; Application number is 201020254294.8; As shown in Figure 1; Comprise the copper screw bolt (1) that is connected with power supply, and the binding post (2) that joins with this copper screw bolt (1) bottom, and this binding post (2) links to each other with copper hank knotting lead (7) through disc-shaped insulator insulator (6); Said copper screw bolt (1) puts interface (12) end face formation hermetically-sealed construction through the set sealing gasket (3) of metal fixed cover (4) and metal fixed cover (4) lower end of socket on it with the disc-shaped porcelain insulator; It is characterized in that: the binding post (2) that said copper screw bolt (1) bottom joins is to establish the cavity cylindrical structure in one, and is provided with the cavity that holds copper hank knotting lead (7) termination melt zone (8) in this cavity.
There is big hidden danger in this kind structure: the copper tip lower end is a cavity cylindrical structure; And the cavity inner top surface is parallel with the metallic sheath inner surface, and the degree of depth has surpassed copper tip pedestal lower plane, after the fusion of tin-coated copper twisted wire head; Insert this endoporus until the top, connect with punch ram then.There is bigger hidden danger in this structure: because this top, binding post hole has surpassed the pedestal lower plane, for being connected maximum weak spot, the tin-coated copper twisted wire is fusion in addition in cavity cylinder and junction, lower flange plane; Still have certain interval, when connecting, externally under the big pressure of punch press; Because no excessive copper sheathing secondary tightens up, deflection is big when compressing, at easy of crack of the root that connects weakness or fine crack; Fine crack is difficult for finding; In use can not each all do pull test, during in actual use through big electric current or Short-Circuit High Current test, the phenomenon that easy local pyrexia comes off or ruptures.
The second way is as shown in Figure 2, and binding post pedestal lower end is a hollow cylinder, and is a planar structure, after the fusion of tin-coated copper twisted wire head, inserts this endoporus until the top, and tin-coated copper twisted wire and binding post have certain interval, are fixed with hydraulic tongs then.This kind structure has certain hidden danger; The contact area of copper stranded conductor junction and the pressure of hydraulic tongs and area have certain relation, and compressing the back is not disc all around, and cylinder inner groovy contact-making surface is not complete whole real face under copper stranded conductor and the binding post; There is certain virtual connection to touch; Certain hidden danger is arranged on the through-current capability of electric current, and in Short-Circuit High Current test heating fracture easily, also easy heating causes power failure in running.
The third mode is as shown in Figure 3; Binding post pedestal lower end is the plane, and shrinkage pool is inner in the binding post base thread, with tin-coated copper twisted wire head with the tin fusion after; Insert the binding post endoporus; Pour into tin through heating from gap location,, guarantee that the junction is solid then from terminals rim of the mouth and the soldering once more of tin-coated copper twisted wire.This kind structure has certain hidden danger, because binding post is a brass, the tin-coated copper twisted wire is a red copper, connects through tin, has added a kind of additive in the tin, and when passing through big electric current, because contact resistance is bigger, in running, being somebody's turn to do the place can generate heat and the influence use.
More than three kinds of connected modes when power consumer carries out big short circuit current test, all occurred because the junction heating, the tin-coated copper twisted wire come off or the contact position temperature high, big electric current unpassable situation.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure; Easy to use; Guarantee that the tin-coated copper twisted wire combines with binding post closely; Do not add simultaneously external solvent yet, guarantee should place's electric current through-current capability greatly, be not easy to occur on a kind of capacitor that local pyrexia causes power failure with press insert type insulator binding post and copper stranded conductor jockey
In order to overcome the deficiency of prior art; The technical scheme of the utility model is to solve like this: a kind of press insert type binding post and twisted wire jockey that connects high-voltage power capacitor comprises binding post pedestal, copper pipe, tin-coated copper twisted wire; The special character of the utility model is that an end of said binding post pedestal is the cylinder copper screw bolt; The other end is a hollow circle binding post, and said tin-coated copper twisted wire one end connects a copper pipe, and tin-coated copper twisted wire one end of said band copper pipe inserts and is connected to hollow circle binding post bottom; Said hollow circle binding post appearance has pit through mould, punch ram, and said pit top forms extruding with copper pipe and is connected.
Said hollow circle binding post blind hole inner top be one section solid, the top of the face outside its solid section face is 60 ° a isosceles triangular structure.
Dash on the said hollow circle binding post at least four pits are arranged.
The length that said hollow circle binding post blind hole inner top is solid section is 2mm～5mm.
Said copper pipe is copper tube or brass tube.
Face of said binding post pedestal is made as the enhancing hexahedron, and another face is provided with at least two intervals and strengthens annulus.
The utility model compared with prior art has simple in structure, easy to operate; Stability is high, guarantees that the tin-coated copper twisted wire combines with binding post closely, and the tin-coated copper twisted wire of band copper pipe combines closely with the cylinder copper screw bolt; Need not add external solvent, bear the pulling force height, open circles binding post place does not ftracture; Guarantee that this place is big through the discharge capacity of electric current, be not easy to occur the characteristics that local pyrexia causes power failure.
