Abstract
The utility model relates to a movable contact of a circuit breaker, mainly solving the problems that a conductive strip is inconvenient to assemble and the assembly efficiency is low during assembly of the existing contact. The movable contact of the circuit breaker is characterized in that the inner part of a contact cover (3) has a hollow structure; and at least one side on the conducting strip (2) is provided with a positioning boss (5). The contact cover and the conductive strip of the movable contact of the circuit breaker are improved so that the assembly of the conducting strip is convenient and rapid during the assembly of the movable contact, and the assembly efficiency is improved.
Description
Technical field
The utility model relates to the parts on the circuit breaker, is specifically related to a kind of moving contact of circuit breaker.
Background technology
Moving contact is the vitals in the circuit breaker, existing moving contact mainly is made up of contact base, conducting strip and Contact Cover, a plurality of conducting strips stack and are connected on the contact base by the bearing pin that passes conducting strip, Contact Cover is provided with the grid sheet, the adjacent conductive sheet is separated by the grid sheet, promptly adopts the grid sheet on the Contact Cover that conducting strip is located.There is following defective in this moving contact: because conducting strip is between the grid sheet on the Contact Cover, need each conducting strip is corresponding with the space of grid sheet on the Contact Cover respectively when assembling, and to install inconveniently, efficiency of assembling is low.
The utility model content
Conducting strip inconvenience, deficiency that efficiency of assembling is low are installed when overcoming the assembling of existing moving contact, the utility model provides a kind of moving contact of circuit breaker, the moving contact of this circuit breaker improves Contact Cover and conducting strip, make moving contact when assembling, conducting strip is installed easily and fast, improved efficiency of assembling.
The technical solution of the utility model is: a kind of moving contact of circuit breaker comprises contact base, conducting strip and Contact Cover, a plurality of conducting strips stack and are passed by bearing pin, the two ends of bearing pin are installed on the contact base, the both sides side plate of Contact Cover is provided with installing hole, the inside of Contact Cover is hollow structure, and at least one side is provided with positioning boss on the conducting strip.
Described boss is at least 2.
Pack into the end of contact base of described conducting strip is provided with groove.
The utlity model has following beneficial effect: owing to take such scheme, cancelled the grid sheet of Contact Cover inside, simplified the structure of Contact Cover, make Contact Cover easy to process, penetrating bearing pin after when assembling stacks each conducting strip buckles well Contact Cover again and gets final product, do not need again conducting strip is correspondingly with Contact Cover, easy to assembly, improved efficiency of assembling.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, Fig. 3, shown in Figure 4, a kind of moving contact of circuit breaker comprises contact base 1, conducting strip 2 and Contact Cover 3, a plurality of conducting strips 2 stack and are passed by bearing pin 4, the two ends of bearing pin 4 are installed on the contact base 1, the both sides side plate of Contact Cover 3 is provided with installing hole 6, the inside of Contact Cover 3 is hollow structure, and at least one side is provided with positioning boss 5 on the conducting strip 2.Owing to cancelled the grid sheet of Contact Cover 3 inside, simplify the structure, make Contact Cover 3 be convenient to processing, raw material have been saved, penetrating bearing pin 4 after when assembling stacks each conducting strip 2 buckles well Contact Cover 3 again and gets final product, do not need again conducting strip 2 is correspondingly with Contact Cover 3, easy to assembly, improved efficiency of assembling.
By shown in Figure 4, described boss 5 is at least 2.Boss 5 is by the punching press one-shot forming, and boss 5 plays the role of positioning, and can guarantee between each conducting strip 2 to keep to be parallel to each other and guarantees relative position between each conducting strip 2.
By shown in Figure 4, pack into the end of contact base 1 of described conducting strip 2 is provided with groove 7.In groove 7, connect pigtail lines, avoid pigtail lines to clamp-on between the adjacent conductive sheet 2.
Claims (3)
1. the moving contact of a circuit breaker, comprise contact base (1), conducting strip (2) and Contact Cover (3), a plurality of conducting strips (2) stack and are passed by bearing pin (4), the two ends of bearing pin (4) are installed on the contact base (1), the both sides side plate of Contact Cover (3) is provided with installing hole (6), it is characterized in that: the inside of Contact Cover (3) is hollow structure, and conducting strip (2) is gone up at least one side and is provided with positioning boss (5).
2. the moving contact of a kind of circuit breaker according to claim 1, it is characterized in that: described boss (5) is at least 2.
