Description

Built-in threading type circuit breaker

Technical field

The utility model relates to the electrical control distribution box device, particularly a kind of miniature circuit breaker.

Background technology

Present miniature circuit breaker has series such as C65, D247, presses the distribution box that certain scheme combination becomes by the circuit breaker of different size, is widely used in fields such as dwelling house, school, office, industry.But present miniature circuit breaker inlet wire mode all is a vertically inlet wire of upper end, and each output loop all needs to be connected (see figure 7) with the lead-in circuit breaker leading-out terminal with insulated conductor in distribution box.There is following shortcoming in this connected mode: 1, the lead consumption is big; 2, need to solve the problem that multiple conducting wires is crimped onto easy loose contact in the binding post simultaneously; 3, distribution box is in the process of manufacturing, and operation is many, it is long to expend man-hour; 4, the end of incoming cables electrified body exposes, and fail safe is not high.5, binding post is loosening easily, heating.

The utility model content

For remedying above-mentioned deficiency, the utility model provides the built-in threading type circuit breaker of a kind of side threading.

The same with conventional circuit breaker, the built-in threading type circuit breaker of the utility model as required, be divided into one pole, the two poles of the earth, three grades and level Four, many groups be used in combination side by side.

The built-in threading type circuit breaker of the utility model comprises switch main body, binding post and entrance hole, and wherein: entrance hole is located at the switch main body upper side, and is through hole, the embedded concentric copper ring of through hole, and the top is provided with the line ball screw.

Described switch main body is divided into one pole, the two poles of the earth, three utmost points or four utmost points, all be provided with four described entrance holes on each switch main body in one group, be respectively A phase, B phase, C phase and N mutually, the copper ring in each phase entrance hole connects the switch static contact of corresponding switch main body respectively with annealed copper wire.

After described switch main body is organized combination more and finished, can form the entrance hole threading passage of four levels, in the hole of needs, penetrate the 2.5-16mm isometric with switches set in the side ²Copper rod, fastening successively then line ball bolt is finished connection; Inlet wire is introduced by the binding post of first group of switch main body bottom, and outlet is drawn (following inlet wire scheme) by other lead terminal of respectively organizing the bottom.Or the total input-wire switch is made of a normal circuit breaker, and total input-wire is received the regular tap upper end, by adapter unit the outlet of service entrance switch lower end is transferred to the switch upper end, adapter unit with go out wiretap and be connected (last inlet wire scheme) with copper rod.

Described line ball screw is provided with the shutoff of rubber safety.

The built-in threading type circuit breaker of the utility model, compact conformation, it is few to install and use connecting line, few when taking a lot of work, and the insulation fully of entrance hole part has improved usage safety performance.

Embodiment

Below in conjunction with embodiment the built-in threading type circuit breaker of the utility model is done more detailed explanation.

Fig. 1-Fig. 3 is respectively front view, end view, the vertical view of the built-in threading type circuit breaker of the utility model.

The built-in threading type circuit breaker of the utility model comprises switch main body 1, binding post 3 and entrance hole 2, and entrance hole 2 is located at switch main body 1 upper side, and is through hole, entrance hole 2 embedded concentric copper rings 5, and the top is provided with line ball screw 7 (see figure 4)s.

Switch main body 1 tetrad, be respectively A phase, B phase, C phase and N switch main body 1 mutually, all be provided with four entrance holes 2 on each switch main body 1 in one group, be respectively A phase, B phase, C phase and N (see figure 2) mutually, the copper ring 5 in each phase entrance hole 2 connects the switch static contact (see figure 4) of corresponding switch main body 1 respectively with annealed copper wire 9.

After switch main body is organized combination more and finished, can form the entrance hole threading passage of four levels, penetrate the 2.5-10mm isometric therein with switches set in the side ²Copper rod 6 (seeing Fig. 4, Fig. 5, Fig. 6), fastening successively then line ball bolt 7 is sealed up rubber safety shutoff 8, finishes connection; Inlet wire 10 is introduced by the binding post 3 of first group of switch main body bottom, and outlet is drawn (see figure 5) by other lead terminal 3 of respectively organizing the bottom.

Aforesaid way is lower end inlet wire mode commonly used.

As needs upper end inlet wire, then need add 12 switchings of a transition element in service entrance switch main body 1 rear end, transition element 12 width are a normal bit (18mm), and transition element 12 upper ends are identical with threading type killer switch main body 1 structure, and the lower end is identical with the normal circuit breaker construction of switch.Lead-in circuit breaker 11 adopts regular tap, and inlet wire 10 connects the upper terminal of lead-in circuit breaker 11, and its lower end terminal outlet 13 is connected with transition element 12, and transition element 12 upper end entrance holes 2 are connected with other outlet switch main body 1 usefulness copper rod 6.

The novel distribution box of built-in threading type circuit breaker and traditional distribution box performance comparison: (with common 50A, 24, the home-use distribution box of 220V is an example)

At present China's distribution box consumption is huge, the distribution box of forming by built-in threading type circuit breaker than traditional scheme have the resource of saving, manufacturing efficient height, characteristics such as cost is low, fail safe is good, have certain popularization value.
