Abstract
The utility model relates to a contact apparatus of a plastic circuit breaker draw-out type apparatus, including a support, a static contact, a moving contact and a plate spring. The support is provided with an up-and-down through hole; the static contact extends into the support and is fixedly connected with the support; the terminations of the left and right side walls of the support extend inward to form blocks; block grooves are formed between the two side upper and lower blocks and the inner wall; the plate spring and the moving contact are arranged in the left and right block grooves; the center positions of the left and right inner walls of the support are provided with projections; and the projections support the plate spring and fix the moving contact in the block groove. The contact apparatus of a plastic circuit breaker draw-out type apparatus is characterized in that the plate spring is correspondingly provided with a gap, a good communication effect is possessed, a compacter structure with a low temperature rise is provided, and a higher production efficiency and lower energy consumption are possessed.
Description
Technical field
The utility model relates to the contact system of breaker of plastic casing withdrawing device, focuses on the technology and the process modification of contact system in the withdrawing device of moulded case circuit breaker, belongs to low tension switch attachment technique field.
Background technology
In professional and complete low voltage electrical apparatus industry, the withdrawing device contact system of existing moulded case circuit breaker mainly contains petal contact system and cutter type contact system.The utility model belongs to the category of cutter type contact system.
Relatively with petal contact system, it is many that cutter type contact system has a contact point, the temperature rise that produces when helping reducing the withdrawing device operate as normal.
Traditional cutter type contact system is because component part quantity is more, and processing technology is advanced inadequately; Cause manual work, material, the waste of the energy; Therefore develop a kind of component part negligible amounts, be convenient to produce, the cutter type contact system of energy savings and material is particularly necessary.
Summary of the invention
The utility model purpose is to provide for the deficiency that overcomes prior art that a kind of to have a temperature rise that better connection effect promptly produces lower, compact structure more, higher production efficiency, the contact apparatus of the breaker of plastic casing withdrawing device of lower power consumption.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of contact apparatus of breaker of plastic casing withdrawing device includes support, fixed contact, moving contact and leaf spring; Said support is provided with the through hole that communicates up and down; Fixed contact stretches in the support and is fixing with it, and the termination of the support left and right sides sidewall formation block that extends internally forms draw-in groove between upper and lower block in both sides and the inwall; Leaf spring and moving contact are installed in the draw-in groove of the left and right sides; The center of the left and right inwall of its support is provided with projection, and projection props up leaf spring and makes it moving contact and be fixed in the draw-in groove, and correspondence offers breach on the said leaf spring.
More excellent is that said support back is offered porose.
More excellent is that said support is that aluminum alloy materials is processed.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
(1) the cutter type contact system of employing the utility model, by the dynamic and static contact and the leaf spring of drawing and forming, support is formed; It is lower on the basis of original cutter type contact system advantage, to have simultaneously the temperature rise that better connection effect promptly produces again, compact structure more, higher production efficiency, lower power consumption.
(2) to use aluminium alloy instead be the support that material is made through smart casting mode to the utility model, and in the perforate of support back, can make air form convection current, on the basis that has solved the intensity decreases problem, make contact system have better radiating effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the utility model end view;
Wherein: 1, support; 2, fixed contact; 3, moving contact; 4, leaf spring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The contact apparatus of the described a kind of breaker of plastic casing withdrawing device of the utility model shown in accompanying drawing 1, accompanying drawing 2 includes aluminum alloy materials and processes support, fixed contact, moving contact and leaf spring, and support is provided with the through hole that communicates up and down; Fixed contact stretches in the support and is fixing with it; The termination of the support left and right sides sidewall formation block that extends internally forms draw-in groove between upper and lower block in both sides and the inwall, and leaf spring and moving contact are installed in the draw-in groove of the left and right sides; The center of the left and right inwall of its support is provided with projection; Projection props up leaf spring and makes it moving contact and be fixed in the draw-in groove, and correspondence offers breach on the said leaf spring, and the support back is evenly distributed with a plurality of long lumbar holes.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
Claims (3)
1. the contact apparatus of a breaker of plastic casing withdrawing device; Include support, fixed contact, moving contact and leaf spring, said support is provided with the through hole that communicates up and down, and fixed contact stretches in the support and be fixing with it; The termination of the support left and right sides sidewall formation block that extends internally; Form draw-in groove between upper and lower block in both sides and the inwall, leaf spring and moving contact are installed in the draw-in groove of the left and right sides, the center of the left and right inwall of its support is provided with projection; Projection props up leaf spring and makes it moving contact and be fixed in the draw-in groove, and it is characterized in that: correspondence offers breach on the said leaf spring.
