Abstract
The utility model discloses a wire connecting terminal structure of a dry type transformer, which comprises a bolt, a branching plate and a copper lug. The branching plate and the copper lug are fixed on the bolt by nuts. The nuts are connected on the two surfaces of the copper lug in a threaded manner, and a thin nut is also connected outside the nut at the outer side of the copper lug in a threaded manner. Compared with the prior art, the wire connecting terminal structure avoids direct contact between the copper lug and the branching plate (an insulating piece); the two surfaces of the copper lug are in contact with the nuts, which enhance the lead wire connecting reliability. The wire connecting terminal structure perfects the techniques and further improves the electric performance of products.
Description
Technical field
The utility model belongs to the transformer accessory technical field, particularly a kind ofly is applicable to many group dry-type transformer binding posts.
Background technology
Original dry-type transformer connection terminal structure (as shown in Figure 2), binding post is made up of bolt 11, copper lug 12, tapping plate 13, plain cushion 14, high nut 15, insulation nut 16.Along with the expansion of occupation rate of market, technical matters is more and more ripe, in order further to strengthen the reliability that transformer lead connects, so the transformer connection terminal structure that we have proposed to improve.
Summary of the invention
The utility model provides a kind of improved connection terminal structure at the deficiency of existing dry type variable-frequency transformer connection terminal structure, strengthens the reliability that transformer connects lead-in wire by this structure, guarantees the electric property of product.
The technical solution of the utility model is, a kind of dry type variable-frequency transformer connection terminal structure comprises bolt and is fixed on tapping plate and copper lug on the bolt by nut, and nut all has been threaded on the two sides of described copper lug.
A thin nut also has been threaded outside described copper lug nut outside.
Compare with original technology, the utility model has avoided copper lug directly to contact (insulating part) with tapping plate, and the two sides is to contact with nut, has strengthened the reliability that lead-in wire connects.Technology that the utility model is perfect has further improved the electric property of product.
Description of drawings
Fig. 1 is the connection terminal structure view of existing utility model.
1 is bolt among the figure, and 2 is plain cushion, and 3 is terminal block, and 4 is the bullet pad, and 5 is copper lug, and 6 is nut, and 7 is thin nut.
Fig. 2 is original transformer connection terminal structure view.
11 is bolt among the figure, and 12 is copper lug, and 13 is terminal block, and 14 is plain cushion, and 15 is high nut, and 16 are exhausted thin nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
Embodiment 1: as shown in Figure 1, bolt 1 and plain cushion 2 pass in the terminal block 3 corresponding apertures, at the another side of terminal block 3, wear plain cushion 2, bullet pad 4 and nut 6, and then go up copper lug 5, are wearing nut 6 at the another side of copper lug 5, at last with thin nut 7 lockings.Copper lug and lead-out wire welding.
