Abstract
The utility model belongs to the technical field of electric power and particularly relates to an assembly electrically connected with a molded case circuit breaker, which comprises a molded case circuit breaker and a first conducting wire. The molded case circuit breaker comprises a shell and a wiring terminal. The shell is provided with an accommodating space used for mounting the wiring terminal. One end of the first conducting wire is connected with a first wiring lug. The assembly electrically connected with the molded case circuit breaker also comprises a supporting insulator, a second conducting wire and a bolt used for the fixed connection of the first conducting wire and the second conducting wire. According to the technical scheme of the utility model, the reliability of the power supply is improved, so that the occurrence of electric shock accidents is effectively avoided. Meanwhile, the burnout of electrical equipment and the occurrence of fire accidents due to the inter-phase disconnection are avoided, so that the safe operation of the power grid is ensured. In addition, the fault rates of both the molded case circuit breaker and a cable are lowered and the consumption of materials is therefore greatly reduced. The maintenance workload is lowered. The safety level of molded case circuit breaker equipment is also improved.
Description
Technical field
The utility model belongs to the power technology field, relates in particular to a kind of assembly that electrically connects with breaker of plastic casing.
Background technology
Breaker of plastic casing can cut off electric current automatically after electric current surpasses the escape set point, play the effect of Electrical Safety, moulds shell and refers to the shell that is used as breaker of plastic casing with plastic insulation, is used between the insulated conductor and the grounded metal part.Requisite meeting relates to big cable end and is connected with breaker of plastic casing in electric installation process, since big cable end with adopt aluminium to arrange after the binding post of breaker of plastic casing picks out being connected of breaker of plastic casing usually to be connected with big cable end again, because less the rocking a little of distance can cause phase fault to take place between the aluminium row, has potential safety hazard.
Summary of the invention
The purpose of this utility model is that a kind of safe and reliable assembly that electrically connects with breaker of plastic casing of being convenient to is provided at above-mentioned the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of assembly that electrically connects with breaker of plastic casing, this assembly comprises breaker of plastic casing and first lead, breaker of plastic casing comprises housing and binding post, housing is manufactured with the accommodation space that binding post is installed, first lead, one end connects the first wiring nose, it is characterized in that: the assembly that electrically connects with breaker of plastic casing also comprises supporting insulator, second lead with fixedly connected the bolt of first lead and second lead, the two ends of second lead all are shaped on the second wiring nose, the second wiring nose, one end is annulus portion, the other end of the second wiring nose is trapezoidal portion, the size in the hole of annulus portion and the binding post of breaker of plastic casing coupling, the outside size of annulus portion and the accommodation space coupling of breaker of plastic casing housing.
Preferably, second lead is selected multiply soft copper heart yearn for use.
The beneficial effects of the utility model are: the utility model has improved power supply reliability, has effectively avoided accident of human electric shock, the alternate electrical equipment that causes of opening circuit to burn out and the generation of fire incident, has guaranteed the safe operation of electrical network; Reduce the spoilage of breaker of plastic casing and lead simultaneously, thereby significantly reduced the loss of material, reduced the workload of safeguarding, improved the lsafety level of breaker of plastic casing equipment.
