Abstract
The utility model discloses a kind of epoxy cast dry transformer connector lug with boss structure, the front end of this connector lug is provided with boss, and boss is positioned at wiring place of cast panel-mounted; Boss exceeds casting area board plane 4-6mm, and installed surface and the brace of boss are suitable.Boss exceeds casting area board plane 5mm.Be connected to fastening bolt on boss and pad is common standard part.The installed surface of boss and brace close contact.The utility model is simple for structure, and fully ensure that the reliability of assembling, meets Production requirement.
Description
Technical field
The utility model belongs to transformer manufacture technology, relates to a kind of epoxy cast dry transformer connector lug with boss structure.
Background technology
The connector lug brace mounting structure of conventional epoxies dry-type transformer as shown in Figure 1.Brace 11 is directly installed in connector lug 12 plane, by fastening bolt 13, and the component compression fit such as pad.By adjusting the upper-lower position adjustment output voltage of brace.All the time, connector lug and casting mold all in one plane, consider the reliability of assembling, and fastening bolt and relevant pad etc. must be all full copper parts, to ensure that contact resistance reaches requirement, operationally overheatedly can not cause failure of insulation.
This structure, through Long-Time Service, proves robust.But the parts such as the required fastening bolt pad of its assembling are all full copper materials, and market does not have unified sale, all needs customized separately, and the production cycle is long, and Costco Wholesale is high; The fastening bolt plasticity of copper material is enough in addition, but rigidity is not enough, as the undue force when assembling, bolt body position will be made to break at inside connector lug, for follow-up work causes great trouble, even cause whole coil 14 to be scrapped.Along with being growing more intense of market competition, just need to research and develop a kind of brand new to substitute.
Summary of the invention
The purpose of this utility model is to provide a kind of epoxy cast dry transformer connector lug with boss structure, and this connector lug is simple for structure, and fully ensure that the reliability of assembling, meets Production requirement.
The purpose of this utility model is achieved through the following technical solutions:
There is an epoxy cast dry transformer connector lug for boss structure, it is characterized in that: the front end of this connector lug is provided with boss, and boss is positioned at wiring place of cast panel-mounted; Boss exceeds casting area board plane 4-6mm, and installed surface and the brace of boss are suitable.
In the utility model, boss exceeds casting area board plane 5mm.Be connected to fastening bolt on boss and pad is common standard part.The installed surface of boss and brace close contact.
The utility model processes a boss in cast panel-mounted connector lug position, and boss exceeds panel plane and is about about 5mm, and the coil lead after moulding by casting just forms a boss structure.During brace assembling, method is with the same above, and difference is that the parts such as all fastening bolt pads can be alternative with common standard part.Theoretical foundation is: in traditional structure, and fastening bolt pad will play compression and double effect of conducting electricity; And in the utility model, fastening bolt only plays pressuring action, because brace fully contacts with the boss installed surface of connector lug, contact resistance is enough little, meets electric property needs only to need tightened bolt presses just can ensure.
The utility model has the advantage of: the processing of panel convex platform groove only need be transformed on original mould, mould can not be caused to waste.Instead of full Copper fabrication part with common standard part, saved raw material, effectively controlled cost, improve the versatility of product.Conventional criteria part has enough rigidity, can not produce the phenomenons such as bolt fracture, cause waste of material.

Embodiment
Have an epoxy cast dry transformer connector lug for boss structure, see Fig. 4 to Fig. 7, the front end of this connector lug is provided with boss 1, and boss 1 is positioned at wiring place of cast panel-mounted; Boss 1 exceeds cast panel 2 plane 5mm, and installed surface and the brace 3 of boss are suitable.The installed surface of boss and brace close contact.
Fig. 4 adopts mounting structure schematic diagram of the present utility model, and in Fig. 4,3 are braces, 4 are coils, 5 are fastening bolts, 6 is connector lugs.Coil lead after moulding by casting forms a boss structure.During brace assembling, method is with traditional the same, and difference is that the parts such as all fastening bolt pads can be alternative with common standard part.In traditional structure, fastening bolt pad will play compression and double effect of conducting electricity; And in the utility model, fastening bolt only plays pressuring action, because brace fully contacts with the boss installed surface of connector lug, contact resistance is enough little, meets electric property needs only to need tightened bolt presses just can ensure.
This structure, in production application, never produced the quality problems such as connector lug is overheated, proved that this structure was reliable.This structure has saved a large amount of copper materials simultaneously, also meets the production economizing type of country's proposition, the requirement of energy-saving product.
