Abstract
AC contractor is a contractor, which mainly solves the dust-proof problem of present contractor, promotes the contractor protection grade and work reliability, and the AC contractor application scope is extended. The AC contractor comprises a shell, a protection cover and universal contact, a coil, a armature, a magnetic yoke etc. The upper and lower shell adopts L-shaped concave-convex structure assembly, the coil and magnetic yoke are completely arranged inside the shell; the two auxiliary protection covers adopt insertion type structure, coattail shaped transparent protection cover is arranged on the middle of the upper part end cover, and a arch shaped flake structure is arranged on the both sides of the upper shell middle part. Besides being used in common circuit, the AC contractor also can be used in places of heavy dust or bad environment, such as welding machine, weaving machine, cement plant and flour plant etc.
Description
Technical field
The utility model relates to a kind of contactor, specifically is a kind of A.C. contactor.
Background technology
Existing contactor construction has following defective: 1. upper and lower casing connection pattern is the plane combination, and sealing is poor, the perforate of structure many places, and dust enters easily, influences the functional reliability of magnetic system element; 2. cut open on and be Open architecture, dust very easily falls into, and diminishes the operate as normal of contact system and magnetic system, has also limited the range of application of product.
Summary of the invention
The utility model mainly solves the dustproof problem of A.C. contactor, to improve the functional reliability of product, reduces the requirement to environmental condition, widens range of application simultaneously.
The technical solution of the utility model is as follows: A.C. contactor comprises housing, contact, coil, armature, yoke, protective cover etc., housing is made up of upper shell 1 and lower house 2, the two adopts L shaped concaveconvex structure to cooperate, coil 11 and yoke 10 are contained in the lower house 2, in the groove that two protective covers 8 insert on the upper shells 1, end cap 4 is equipped with on upper shell 1 top, end cap 4 middle part tappings are equipped with top protection cover 5, the two adopts dovetail type to connect, 1 liang of middle side part lower end of upper shell inwall is shaped on arcuate recess 13, makes housing wall become the arch flake structure.
The beneficial effects of the utility model and existing A.C. contactor relatively, the new shape of this practicality has following advantage: 1. the built-in loop construction of employing, coil are packed in the lower house fully, make to expose quiet iron and be protected, and have improved the degree of protection of product; 2. adopt L shaped cooperation between upper and lower casing, increased contact-making surface, effectively stop dust to enter housing; More than two make the product magnetic system obtain good protection, improved the magnetic system functional reliability.3. the both sides protective cover adopts plug in construction, and is easy to assembly, and can stop dust to enter; 4. use the dovetail type respective outer side edges between top protection cover and the housing end plug, in conjunction with tight, it is convenient to load and unload, because the top protection cover is that transparent material is made, is convenient to observe its operating state; More than two prevented that effectively dust from entering contact system, improved the reliability of contact system.5. the housing middle part has the arch flake structure, punches thin slice and can form the interlocking contactor.
