Abstract
The utility model relates to a kind of voltage current transformer shell.Shell one-shot forming, the bottom of shell is the face having pin bores, has some pillars around pin bores, and shell has an opening.Coordinate with dedicated pin pin, pin pin is fixing after outer casing bottom passes from the inside to surface, and install the rear curable epoxide of inner core welding, closure of openings completes instrument transformer assembling.The utility model can reduce skeleton, reduces production cost, improves the reliability of product.
Description
Technical field
The utility model relates to a kind of voltage current transformer, particularly a kind of voltage current transformer shell.
Background technology
The voltage current transformer adopted in the market, except punching current transformer is after inner core conductor and pin pin weld, the pin bores of pin pin on shell can be passed from the inside to surface, shell can outside one-shot forming, other voltage current transformer first fixes pin pin, then weld, need skeleton to fix pin pin, shell can not one-shot forming.The one-shot forming of punching current transformer casing, bottom surface there is pin bores, the face of opening is the face with bottom surface neighboring vertical, bottom surface does not have pillar can fix pin pin and pin pin and inner core is kept certain distance, assembling first inner core conductor is wound around with metal needle to weld, again pin pin is passed shell pin bores from the inside to surface, finally inner core is put into shell, in assembly manipulation process, inner core does not have shell to protect for a long time, likely damage inner core, and inconvenient operation, easily cause inner core conductor to break; The assembling of other voltage current transformer first inner core is put into shell, metal needle is fixed in skeleton pin bores, again inner core conductor directly or by after the transition of thick lead-in wire, be wound around with the metal needle be fixed on skeleton and weld, finally skeleton is built, operating process is inconvenient, easily causes inner core conductor to break, operating process is many, and cost of labor is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly does not need skeleton, shell one-shot forming, be suitable for various voltage current transformer, the voltage current transformer shell of the low and convenient and reliable production of cost.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of voltage current transformer, comprises shell, and described shell is one-shot forming, outer casing bottom has pin bores, has some pillars around pin bores, little large below above pillar, pillar has some salient points, shell has an opening
For one-time formed cylinder blanket, this opening is exactly the open top of shell,
For one-shot forming square shell, this opening can be top as opening, also can be an adjacent surface of bottom surface as opening,
For punching current transformer casing, this opening is exactly that opening is done in a face vertical with punching current aperture.
The beneficial effects of the utility model are: shell one-shot forming is produced, and do not need skeleton, cost is low.Adopt shell of the present utility model and the supporting voltage current transformer as pin pin, inner core conductor is not that manual being wound into metal needle is welded or welded by thick lead-in wire being wound on metal needle by hand after welding slightly lead-in wire transition, then assemble, but in larger space outerpace and thick wire bonds, space is large, easy to operate, assembling easily.After pin pin is wound around welding lead or terminal compression joint wire, rear portion is thicker, and diameter is greater than pin bores, connects not worry firmly excessive when pin bores crossed by pin pin, and pin pin drops out, pin pin to pass length consistent, connect pin pin efficiency and improve, pin pin convenient fixing.Inner core directly can be put into and adopt shell of the present utility model once to weld and just complete assembling, and favourable inner core protection, improves product reliability, decrease operational sequence, reduce cost of labor.The lead-in wire thicker than the wire of inner core is adopted to weld with pin pin, or the lead-in wire of terminal compression joint and the wire bonds of inner core, inner core can be improved to the impact capacity of expanding with heat and contract with cold and vibrating of line to the follow-up assemble welding of finished product voltage transformer, effectively solve the FAQs of voltage transformer inner core broken string.Generally, shell of the present utility model, can reduce the cost of voltage current transformer, improves the reliability of product.

embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 7, for the utility model concrete utilization is at a kind of schematic diagram of punching current transformer.
Embodiment
A kind of voltage current transformer, comprises metal needle front portion 1, other one end 3, inner core 8 and the shell 6 of wire one ends wound weld metal pin part 2 and wire.First wire welds after being wound around metal needle, outwards passing from inner from the sizeable pin bores in the relevant position of shell 6 described pin pin 5, it is larger than pin bores that metal needle is wound around welding lead section diameter, it is inner that shell 6 stayed by wire one ends wound weld metal pin part and wire 3, in 2 pillars nearest around L shape pin pin pressure people pin bores, or in 2 pillars nearest around wire pressure people pin bores, fix pin pin.Inner core 8 is put into the inner relevant position of shell 6 along electric current center hole 7, interior core lead 9 is welded with other one end 4 of wire.Pour into curable epoxide, closure of openings, complete the enforcement of punching current transformer.
