Abstract
The utility model discloses a miniature circuit breaker which comprises a shell, an electromagnetic system, an arc extinguish chamber, a wiring terminal, an arc striking wafer and a magnet yoke, wherein the electromagnetic system comprises an iron core, a coil skeleton and a coil, the coil skeleton is sleeved on the iron core, the coil is wound on the coil skeleton, the inner wall of the shell is provided with a positioning clamp slot, and the coil skeleton is directly arranged on the positioning clamp slot. According to the miniature circuit breaker disclosed by the utility model, a bracket of a circuit breaker in the relative background technologies of the circuit breaker disclosed by the utility model is omitted, and when the miniature circuit breaker is installed, a process of riveting the iron core and the bracket is omitted, so that the cost of the miniature circuit breaker is low; and because the bracket and the shell are integrated, the miniature circuit breaker is firmer in structure and more stable in application performance.
Description
Technical field
The utility model relates to a kind of miniature circuit breaker.
Background technology
Circuit breaker is a kind of existing hand switch effect, can transship automatically again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; Do not start asynchronous motor continually; Power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally need not change parts, obtained to use widely.
Existing miniature circuit breaker; Comprise housing, electromagnetic system, striking sheet; Said electromagnetic system comprises iron core, is sleeved on the coil rack of iron core and is wrapped in the coil on the coil rack; Need iron core be riveted on the support, coil rack on the iron core overcoat finally is fixed on iron core and coil rack on the housing through support again.Existing miniature circuit breaker, this project organization is complicated, and trouble is installed, and cost is higher, and structure is insecure, in process is jolted in transportation, damages easily.
The utility model content
The problem that the utility model will solve is to improve the complex structure and insecure, the cost problem of higher of the middle-size and small-size circuit breaker of background technology.
In order to overcome the above problems; The utility model provides a kind of miniature circuit breaker; Comprise housing, electromagnetic system, arc control device, binding post, striking sheet, yoke; Said electromagnetic system comprises iron core, is sleeved on the coil rack of iron core and is wrapped in the coil on the coil rack, and described inner walls is provided with locating groove, and said coil rack is directly installed on the locating groove.
Said electromagnetic system is positioned at directly over the arc control device, is provided with first yoke and the first striking sheet between said electromagnetic system to the arc control device successively, and an end of first yoke is connected in the end that binding post and the other end are butted on the first striking sheet mutually.
Said first yoke comprises yoke body section and yoke striking section; The first striking sheet comprises striking sheet body section and striking sheet bending section; Said yoke body section and striking sheet body section are parallel to each other, and the downward bending of yoke striking section is butted on the upwards striking sheet bending section of bending mutually.
Said yoke striking section is butted on the side towards fixed contact of striking sheet bending section mutually.
The described miniature circuit breaker of the utility model, described inner walls is provided with the locating groove with its one, and said coil rack is directly installed on the locating groove; Make the circuit breaker in the relative background technology of circuit breaker of the utility model omit support; And save the operation that iron core and support are riveted when installing, make cost lower, in addition locating groove and housing one; So structure is more firm, serviceability is more stable.
Description of drawings
Accompanying drawing 2 is the local enlarged diagrams at the B place of Fig. 1;
Accompanying drawing 3 is the local enlarged diagrams at the A place of Fig. 1;
Accompanying drawing 4 is structural representations of described first yoke of the utility model and the first striking sheet.
Marginal data: 1, housing; 2, iron core; 3, locating groove; 4, coil rack; 5, coil; 7, first yoke; 71, yoke body section; 72, yoke striking section; 8, the first striking sheet; 81, arc sheet body section; 82, striking sheet bending section.
Embodiment
Below in conjunction with accompanying drawing a kind of miniature circuit breaker of the utility model is described further.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4; The miniature circuit breaker of present embodiment; Comprise housing 1, electromagnetic system, arc control device, binding post, striking sheet, yoke; Electromagnetic system comprises iron core 2, is sleeved on the coil rack 4 of iron core 2 and is wrapped in the coil 5 on the coil rack 4, housing 1 inwall be provided with locating groove 3, coil rack 4 is directly installed on the locating groove 3.The described miniature circuit breaker of the utility model is through the design of present embodiment; Make the circuit breaker in the relative background technology of circuit breaker of the utility model omit support; And save the operation that iron core 2 and support are riveted when installing, make cost lower, in addition support and housing one; So structure is more firm, serviceability is more stable.
Said electromagnetic system is positioned at directly over the arc control device, and an end that is provided with first yoke 7 and the first striking sheet, 8, the first yokes 7 between electromagnetic system to the arc control device successively is connected in the end that binding post and the other end are butted on the first striking sheet 8 mutually.Said first yoke 7 comprises yoke body section 71 and yoke striking section 72; The first striking sheet 8 comprises striking sheet body section 81 and striking sheet bending section 82; Yoke body section 71 and striking sheet body section 81 are parallel to each other, and the 72 downward bendings of yoke striking section are butted on the upwards striking sheet bending section 82 of bending mutually.Because first yoke 7 needs to connect binding post, also need guide to arc control device simultaneously, so its structure need bend repeatedly, if the one design, its difficulty of processing is bigger, and processing cost is high.Through designing with 8 splits of the first striking sheet, make that its processing is simple, cost reduces.
Said yoke striking section 72 is butted on the side towards fixed contact of striking sheet bending section 82 mutually.This design makes to win and does not intercept between yoke 7 and the arc control device, and first yoke 7 imports to arc control device with electric arc more easily when striking, reach better arc quenching effect, and interrupting performance improves.
The utility model is not limited to above embodiment and conversion.
