Description
Technical field
The utility model is related to, and in particular to a kind of metal contact merges the structure of integrated moving contact with plastic part.
Background technology
The moving contact part of breaker is commonly designed two assembling parts together currently on the market, with metal contact with it is another
Plastic parts assembles.Moving contact is very important a function parts in the structure of low-voltage electrical product, it is desirable that dimensional accuracy
Height, electric property are stablized.The design of product is formed by two assembling parts currently on the market, to individual Element Design dimensional accuracy
It is required that it is high, so that part is of high cost;Size of components precision after another assembly is not high and unstable, is easy to cause the electricity of product
Gas performance cannot meet standard requirement.
Utility model content
The purpose of this utility model be to solve above-mentioned deficiency, provide a kind of metal contact merged with plastic part it is integrated
The structure of moving contact.
The purpose of this utility model is achieved through the following technical solutions:
A kind of metal contact merges the structure of integrated moving contact, including moving contact, bimetal leaf, lock with plastic part
Kinematic link, switch knob, electromagnetic assembly and energy-stored spring, moving contact lower part connect bimetal leaf, moving contact top connection lock
Kinematic link is detained, kinematic link connecting valve handle is latched, moving contact rear portion is provided with electromagnetic assembly, and moving contact top is provided with
Energy-stored spring, moving contact are made of plastic part and metal contact, and metal contact upper end is embedded in plastic part, metal contact
Lower end is arranged outside plastic part.
The lower end of plastic part is provided with plastic channel, and metal contact rear end is embedded in inside plastic channel.
Metal contact upper end is curved in being bent up.
It is provided with mounting hole in the middle part of plastic part.
The utility model has following beneficial effect:
The utility model is designed reasonably, it is easy to use, it can reliably realize that the electric property of stable high-precision size is wanted
It asks, the electric properties such as break-make connection and short circuit breaking to realize relatively reliable product;The compact structure of product simultaneously
Size saves labour cost and material cost.
