Abstract
The utility model provides an insulation end ring of a transformer coil, which comprises a laminated pad. In the technical scheme, an inner cardboard tube is arranged in the laminated pad, and an outer cardboard tube is arranged outside the laminated pad; the inner cardboard tube and the outer cardboard tube are both of a cylindrical shape; and the laminated pad is bonded with the inner cardboard tube and the outer cardboard tube through glue or fixed with the inner cardboard tube and the outer cardboard tube through insulation rivets. The insulation end ring can be tightly connected with the inner cardboard tube of the coil, thereby ensuring the size accuracy of the insulation end ring, achieving high mechanical strength, realizing good pressing effect on the transmission coil, and improving the utilization rate of the cardboard material.
Description
Technical field
The utility model belongs to the transformer mechanical field, relates in particular to a kind of transformer coil insulating end ring.
Background technology
The structure of original coil insulation end circle, normally cut making cardboard circle to width with special-purpose circle according to the diameter and the width of cloth of coil, top is according to coil cushion block position adhesive linkage pressure pad piece (seeing accompanying drawing 3 and accompanying drawing 4), the shortcoming of this structure is that the utilance of cardboard is lower when making the cardboard circle, the structure cardboard circle less to size for the width of cloth, that the cushion block height is big damages in manufacturing process easily, the sticking finished product that makes, move and use in cushion block stable bad, end encloses fragile.
Summary of the invention
The utility model provides a kind of transformer coil insulating end ring, has solved in the background technology to adopt that the cardboard circle damages easily, the unsettled shortcoming of cushion block.
The technical solution of the utility model is achieved in that a kind of transformer coil insulating end ring, comprises the lamination cushion block, establishes interior fiber core in the lamination cushion block, the outer fiber core of lamination cushion block peripheral hardware;
Interior fiber core, outer fiber core are cylindric;
Stick with glue between lamination cushion block and interior fiber core, the outer fiber core and connect or fix with insulated rivet.
The beneficial effects of the utility model are: insulating end ring engages closely with the interior fiber core of coil, guarantees the dimensional accuracy of insulating end ring, and the mechanical strength height is effective to the thrust of transmitting coil, improves the stock utilization of cardboard.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model generalized section;
Fig. 3 is the structural representation of insulating end ring before improving;
Fig. 4 is the generalized section of insulating end ring before improving.
Part explanation: 1, outer fiber core, 2, the lamination cushion block, 3, interior fiber core.
Embodiment
Be further described below in conjunction with accompanying drawing 1 and 2 pairs of the utility model of accompanying drawing: a kind of transformer coil insulating end ring, comprise lamination cushion block 2, fiber core 3 in establishing in the lamination cushion block 2, the outer fiber core 3 of lamination cushion block 2 peripheral hardwares, interior fiber core 3, outer fiber core 1 are cylindric, stick with glue between lamination cushion block 2 and interior fiber core 3, the outer fiber core 1 to connect or fix with insulated rivet.Insulating end ring engages closely with the interior fiber core of coil, guarantees the dimensional accuracy of insulating end ring, and the mechanical strength height is effective to the thrust of transmitting coil, improves the stock utilization of cardboard.
