Abstract
The utility model discloses an organic composite cross arm insulator which is composed of a core rod, an umbrella cover and accessories of end part. The core rod is a compression molding element and is a conical rod shape, a wire-hanging terminal and the core rod are fixedly connected with each other by the compression molding of the core rod, and a metal cap and the core rod are fixedly connected with each other by adopting a back taper platform shape. The utility model has the advantages that the simple and reasonable structure is realized, the finish machining of the accessories of the end part of the utility model are not needed, the low production cost is realized, the bearing strength is relatively large, the shedding phenomenon and the jackknifing phenomenon can not be generated while the utility model is used, etc. The utility model is relatively ideal composite cross arm insulator.
Description
The utility model belongs to the insulator technology that the electric power system high-tension line uses, and is specifically related to have plug, the organic compound cross arm insulator of assembled of umbrella cover and end accessory etc.
The organic compound cross arm insulator of existing this class, all adopt the disclosed name of similar Chinese patent to be called " high-pressure synthetic isolator ", application number is the syndeton form of 95210329.X, its plug system adopts the isometrical rod of FRP fiberglass pulling, being connected between plug and the end accessory metal cap, slipping into the termination by plug and realize by interior key.In actual applications, the organic compound cross arm insulator of this class, ubiquity plug because attaching and must cut open and cause its intensity impaired adds unreasonable structure, often comes off and the jackknifing phenomenon; Metal end accessory structure relative complex designs unreasonablely, and the metal parts requirement on machining accuracy is higher, and even the more high deficiency of production cost.
The purpose of this utility model is that the deficiency to prior art makes improvements, and provide a kind of plug tapered and attaching needn't cut open, end accessory structure is simplified, substantially need not be accurately machined, can not come off in actual applications and the organic compound cross arm insulator of jackknifing phenomenon.
Realize that the purpose of this utility model takes following technical scheme: it is still by galss fiber reinforced resin plug, silicon rubber umbrella cover and comprise that the end accessory of metal hanging wire terminal and metal cap is formed, and said plug is compression molding and to be circular cone bar-shaped, in the hope of under the prerequisite of equivalent material, obtain maximum carrying resistance to bending; Being connected between hanging wire terminal and plug, being that the hanging wire terminal is inserted in the mould of plug mold pressing as inserts, and forming fixedly connected via the plug compression molding; Being connected between metal cap and the plug, then become the inversed taper platform shape fixedly connected.
Preferred metal cap is fixedlyed connected one of scheme and is with the inversed taper platform shape between the plug, big outer little inversed taper platform shape was inserted metal cap in the mould of plug mold pressing as inserts in the endoporus of metal cap was, and it is fixedly connected to form the inversed taper platform shape via the plug compression molding.
Preferred metal cap is fixedlyed connected two of scheme and is with the inversed taper platform shape between the plug, big outer little inversed taper platform shape in the endoporus of metal cap is, plug and metal cap attaching slip into the head be that the A section is isometrical rod, in the territory, chamber between the isometrical place of A section of the inversed taper platform shape inner hole wall of metal cap and plug, filling is provided with the enhancing resin piece, and makes metal cap become the inversed taper platform shape fixedly connected with plug.
Preferred metal cap is fixedlyed connected three of scheme and is with the inversed taper platform shape between the plug, it also has external screw thread and the tapered metal end cover of endoporus, and metal cap is provided with internal thread, become the inversed taper platform shape fixedly connected by the metal end cover with cone-shaped inner hole with plug, metal cap then becomes to be threaded with the metal end cover.
The equal series cast steel spares of end accessory such as the metal cap of being mentioned in the above description of the utility model, metal hanging wire terminal.
The utility model compared with the prior art has simple and reasonablely, and the attached parts of metal end needn't be processed, use can not come off and characteristics such as jackknifing phenomenon, and be conspicuous.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model;
Fig. 3 is another structural representation of the present utility model.
One of the utility model embodiment, see also Fig. 1, the utility model is by galss fiber reinforced resin plug (1), silicon rubber umbrella cover (2) and comprise metal hanging wire terminal (3) and the end accessory of metal cap (4) is formed, and said plug (1) is compression molding and to be circular cone bar-shaped; Metal hanging wire terminal (3) forms via plug (1) compression molding with plug (1) fixedlys connected.When actual fabrication, can slip into the surface of the part of plug (1) in hanging wire terminal (3), default such as hole, pit, spin slot etc. when casting, to strengthen the curable grip between plug (1) and the metal hanging wire terminal (3).Big outer little inversed taper platform shape in the endoporus of metal cap (4) is, and with metal cap (4) as inserts, and it is fixedly connected to form the inversed taper platform shape via plug (1) compression molding.
Two of the utility model embodiment, see also Fig. 2, big outer little inversed taper platform shape in the endoporus of metal cap (4) is, the A section of plug (1) is isometrical rod, in the territory, chamber between the isometrical place of A section of the inversed taper platform shape inner hole wall of metal cap (4) and plug (1), strengthen resin such as epoxy resin by perfusion, strengthen resin piece (5) and be provided with, thereby make metal cap (4) become the inversed taper platform shape fixedly connected with plug (1).Other is all as one of embodiment.
Three of the utility model embodiment sees also Fig. 3, and it also has external screw thread and the tapered metal end cover (6) of endoporus, and metal cap (4) is provided with internal thread.Plug (1) is pressed into from the larger diameter end of the endoporus of metal end cover (6) and installs, thereby makes metal end cover (6) become the inversed taper platform shape fixedly connected with plug (1), and then, metal cap (4) links into an integrated entity by screw thread with metal end cover (6).Other is all as one of embodiment.
The equal series cast steel spare of metal cap (4), metal hanging wire terminal (3) and metal end cover (6) that the utility model is related.
