The composite pin insulator effectively solves the problem that time and labor are wasted when the lead is fixed in a traditional mode. The composite pin insulator has the advantages of simple and reliable structure, convenience in use, high reliability and the like.

Description

Compound needle type insulator

Technical field

The utility model relates to insulator field, specifically a kind of compound needle type insulator.

Background technology

Chinese patent CN102709005A discloses a kind of " exempting from binding insulator ", compares with traditional compound needle type insulator, and the method for its fixing cord saves time, laborsaving.But the upper gold utensil of its fixing cord has 13～15 parts, fabrication schedule is complicated, technological requirement is high.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of background technology, provide a kind of simple in structure, be convenient to manufacture, fixing cord more saves time, labour-saving compound needle type insulator, does not need to utilize binding or bolt during fixing cord.

The utility model adopts the design reduced insulator number of spare parts, thus the processing cost of greatly reducing and improved the convenience that insulator is used.

The technical solution adopted in the utility model is: a kind of compound needle type insulator, comprise gold utensil, lower gold utensil, plug and full skirt, it is characterized in that described upper gold utensil consists of wire constrainer and pedestal, described wire constrainer is ladder constrainer or sawtooth constrainer or П type constrainer; Described pedestal has constrained port and pin-and-hole, the built-in spring pin of described pin-and-hole, and spring pin is fixed on wire constrainer in constrained port.

Described ladder constrainer takes the shape of the letter U, and main body is made of cylindrical metal material, and two end ring are carved some cascade groove.

Described sawtooth constrainer two ends one side is carved with saw-tooth grooves.

Described П type constrainer comprises shank and spring leaf, and described shank two end ring are carved some cascade groove, and spring film trap is carved with in centre.

Described spring pin one end is spring, and the other end has circular-arc breach.

The beneficial effects of the utility model are, simple in structure, easy to process, the upper gold utensil of fixing cord only has 4～5 parts, free-hand during fixing cord wire constrainer are pressed into constrained port, save time, laborsaving.
