Description
Technical field
The utility model relates to a kind of binding post, relates in particular to a kind of connecting terminal components that is used for a winding of current transformer.
Background technology
The binding post of a winding of common current instrument transformer generally is to adopt inserts plug formula or binding post integral structure.Plug formula structure is with in the copper insert embedded hole, and the end line joint of winding or ampere wires joint and copper insert plug formula are connected, and fragile copper insert of this mode and wire terminal reduce useful life, cause work reliable inadequately, and make trouble; The binding post integral structure will be used thicker copper coin in order to reach the dark end of screw thread, expends more copper material, causes cost to raise, and the market competitiveness reduces.
Notification number mainly is a kind of instrument check binding post socket for the utility model patent of CN2886834 provides a kind of plug formula instrument check terminal block, and corresponding electric energy meter and the low-voltage current mutual inductor splicing ear of intending inserting uses.It is characterized in that all jacks are ordered in the rectangular bakelite body shell, in each jack elastic conducting strip are housed, this elastic conducting strip connects with the corresponding wiring of checking table by the crimping screw.As the terminal block of electrical energy meter calibration, its jack is 7～15, and as the terminal block of low-voltage current mutual inductor verification, its jack is 2.The key property of this utility model is to use conveniently, during with verification one inserted and one pulled out taking out stitches of another contact of contact after the wiring that replaces an original contact of a contact of elder generation and the verification, alleviate labour intensity greatly and improved verification efficient, and can avoid contingency to take place.
Notification number provides a kind of binding post box of bushing shell for transformer formula current transformer for the utility model patent of CN201011631, comprise box body, lid and terminal board, lid and terminal board lay respectively at the box body two ends, the screw rod of a band handle is threaded with terminal board from the circle center hole insertion at lid top, with lid, box body, terminal board links together, the box body circle wall is provided with entrance hole, be embedded with the copper nut sleeve that several are used for wiring on the terminal board, the screwed hole at the two ends of the described copper nut sleeve that is used for wiring is not connected blind hole.This utility model makes wiring fastening easy, and connection bolt can not become flexible, thereby guarantees that the current transformer outlet is connected with the reliable of nut sleeve of binding post.
Summary of the invention
The purpose of this utility model provides a kind of reliable operation, long service life, manufacturing is simple, cost is low winding connection terminal assemblies of current transformer.
The utility model is provided with primary connection terminal and steel embedded nut; The primary connection terminal is provided with at least 1 tapped through hole, the steel embedded nut is arranged in tapped through hole, the steel embedded nut is provided with outer surface thread and inner bolt hole, the outer surface thread of steel embedded nut is threaded with tapped through hole on the primary connection terminal, and the thread rotary orientation of steel embedded nut outer surface is opposite with the thread rotary orientation of steel embedded nut internal thread hole.
The thread rotary orientation of the tapped through hole on the primary connection terminal is preferably left-handed, and the thread rotary orientation of steel embedded nut outer surface also is left-handed.The internal thread hole of steel embedded nut is preferably blind hole.The bottom nozzle of the tapped through hole on the primary connection terminal preferably is provided with deep gouge.
The steel embedded nut preferably is the T font, and the perpendicular arm of T Zee bar steel Z embedded nut is positioned at the tapped through hole on the primary connection terminal, and the transverse arm of T Zee bar steel Z embedded nut is close on the bottom surface of primary connection terminal.
Because the utility model adopts said structure, therefore manufacturing of the present utility model and assembling are very simple.During using, the steel embedded nut, do not relate to electric action only for connecting.The steel embedded nut adopts the steel manufacturing, has saved a large amount of copper materials, and has increased bonding strength, and is reliable with being connected of tapped through hole on the primary connection terminal.But the operation of double thread hole secondary brush plating behind the instrument transformer moulding by casting has been saved in the surface nickel plating of steel embedded nut.When the utility model uses, the joint that need be connected with the utility model (as the end line joint or the ampere wires joint of winding) can correspondingly be made the joint that can be threaded with the internal thread hole of steel embedded nut, because the thread rotary orientation of steel embedded nut outer surface is opposite with the thread rotary orientation of steel embedded nut internal thread hole, therefore in the process of joint screw-in steel embedded nut internal thread hole, can revolve tighter and tighter, can eliminate the situation of matching loose fully, even use through permanent, also can not lose efficacy.This shows outstanding advantage such as the utlity model has reliable operation, long service life, manufacturing is simple, cost is low.
