Description

A kind of needle type ceramic insulators special-purpose steel cap

Technical field

The utility model relates to electroceramics attachmentes, are especially for the steel cap that needle type ceramic insulators use.

Background technique

With the fast development of China's electric power, electrotechnical porcelain product dosage also increasingly increases.Porcelain insulator is one of electrotechnical porcelain product, It is and to make to have between energized conductor or between conductor and the earth enough distances and absolutely for supporting and fixing bus and energized conductor The part of edge is to play a part of to support conducting wire in overhead transmission line and prevent electric current from returning ground.

Steel cap is a kind of important part of porcelain insulator product, it does not require nothing more than high mechanical strength itself, is had enough electrical Dielectric strength, moisture resistance and external force resistance (such as wind-force, vibration, pulling force) impact is good, and requires weight light.In the prior art Steel cap mostly uses nodular cast iron or malleable cast iron casting and forming, connect in order to ensure above-mentioned properties and with the mucilage binding of porcelain ontology Reliably, existing steel cap wall thickness is big and less uniform, and the material of heavier-weight, consumption is more, and material cost is higher.

Utility model content

For above-mentioned the problems of steel cap of needle type ceramic insulators in the prior art, the utility model provides one kind Not only structurally reasonable, production is simple, and shaping speed is fast, and Product Precision is high, and surface is smooth, light weight, and mechanical strength is big, matter It measures, product is light and handy, pin insulator special-purpose steel cap easy to use.

Problem to be solved in the utility model is adopted the technical scheme that: the pin insulator special-purpose steel cap passes through glue Dress is integral with the electroceramics bodily form, it includes steel cap ontology, and the steel cap body upper part is the clamping plate that both ends are arc-shaped, steel cap Body lower part is the mucilage binding pipe of cone, is provided with wiring half slot among the clamping plate, is provided in wiring half slot anti- There is side ring body, upper end and clamping plate to be integrally attached to for sliding slot, mucilage binding pipe lower end, and the mucilage binding pipe outer surface is curved surface, Be arranged at intervals with ring tooth socket on mucilage binding pipe inner surface, the mucilage binding tube wall average thickness be clamping plate thickness two/ One, the section radius of the ring tooth socket is a quarter of mucilage binding tube wall average thickness to one third, the side ring body With a thickness of 0.8-1.1 times of mucilage binding tube wall average thickness, intensive aspect, mucilage binding are provided between clamping plate and mucilage binding pipe top It manages and is provided with lower intensive aspect between side ring body, it is average that the thickness of the upper intensive aspect and lower intensive aspect is respectively less than mucilage binding tube wall Thickness.

The mucilage binding tube wall average thickness is that ring tooth socket wave crest and mucilage binding pipe outer surface be most on mucilage binding pipe internal surface The half of big distance and ring tooth socket trough and the sum of the minimum range of mucilage binding pipe outer surface.

The utility model is compact-sized, easily manufactured, and each part is matched and be provided with reinforcement by reasonable structural thickness Body reduces the wall thickness of each part of steel cap in the case where ensuring enough intensity and rigidity, reduces steel cap weight, saves raw material, reduces Cost of material；Second is that being provided with non-slip groove, it is not easy to loosen after wire clamping is fixed, electroceramics integrally not only there are enough mechanical strengths And rigidity, and there is good electrical insulation strength, moisture resistance and external force resistance impact, so that porcelain insulator can be improved Service performance.
