Technical field
The utility model is specifically related to a kind of main contact pedestal of control and protective switching device.
Background technology
Control and protective switching device (being called for short CPS) is owing to being integrated with traditional circuit breaker (fuse), contactor, overload (or overcurrent, disconnected phase) protection relay, starter, the major function of isolator etc., fundamentally solve traditional employing discrete component (normally circuit breaker or fuse+contactor+overload relay) to connect and control and protection that is that cause coordinates irrational variety of problems owing to selecting unreasonable, particularly overcome due to adopt combine between the electric equipment products of different appraisal standards time, protective feature coordinates inharmonic phenomenon with control characteristic, drastically increase the operational reliability of Control and protection system and continuous runnability, from its 26S Proteasome Structure and Function, control and protective switching device is also no longer contactor or the single product such as circuit breaker or thermal relay, but a set of Control protection system.
Based on the advantage of the above-mentioned functions of control and protective switching device, rose progressively year by year to the application of this product in market in recent years, its application has related to such as industrial plants, commercialization and civilian installation, the field such as fire protection equipment and infrastructure, therefore, the range of application of control and protective switching device and the market demand are all very large, but, our company progressively finds in production management process, the housing of the main contact pedestal of the control and protective switching device on existing market is owing to being all one-time formed part, its surface structure is larger, and install dynamic in this housing, the operation more complicated of the parts such as fixed contact and arc-extinguish chamber, even as easy as rolling off a log occur installing coordinate not in place and then need the situation of reprocessing, have impact on production efficiency greatly, simultaneously, due to the feature that base housing volume is larger, not only increase to some extent in material cost, and this product also too takes up room when using and installing, extrude the assembly space of other products.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provide a kind of install simple and reliable, volume is little, the main contact pedestal of control and protective switching device that can effectively enhance productivity.
For achieving the above object, the utility model adopts a kind of main contact pedestal of control and protective switching device, comprise housing, be arranged on binding post in housing and dynamic and static contact, described housing comprises the first side plate, the first intermediate plate, the second intermediate plate and the second side plate that are mutually put together successively, wherein form the first wire connection cavity between the first side plate and the first intermediate plate, form the second wire connection cavity between first intermediate plate and the second intermediate plate, between the second intermediate plate and the second side plate, form the 3rd wire connection cavity; Described housing has the larger rectangular body of lateral separation, and two side positions that lean on of this rectangular body offer at least one fixed installation hole respectively; The bottom of described rectangular body offer guide-track groove by centre position, offer at least one fixed installation hole near the top position of this guide-track groove; The top of described housing, near the position of longitudinal centre line wherein side, there is longitudinally protruding attachment, this attachment offers at least one fixed installation hole.
Further, the wherein side of described guide-track groove is provided with the resilient clip for being fixedly mounted on guide rail.
By the above-mentioned improvement to prior art, the main contact pedestal of control and protective switching device of the present utility model reaches the beneficial effect of following three aspects: 1, because the main contact pedestal of control and protective switching device of the present utility model adopts fabricated structure, by the first side plate, first intermediate plate, second intermediate plate and the second side plate are put together successively, and then form the first wire connection cavity being used for external power supply or equipment respectively, second wire connection cavity and the 3rd wire connection cavity, therefore, not only structure is simple for main contact pedestal of the present utility model, and the assembly process simplified greatly, effectively improve your production efficiency of staff, 2, housing due to main contact pedestal of the present utility model has the larger rectangular body of lateral separation and is opened in the guide-track groove of bottom and upwards longitudinally protruding attachment, and it is aforementioned known, this housing is put together by multiple plate profile structure, analyze from amechanical angle, this housing be put together belongs to fragile region in the two ends of rectangular body and the guide-track groove position of bottom and the position of attachment, directly have influence on the reliability and stability that main contact pedestal is installed, therefore, housing of the present utility model is provided with at least one fixed installation hole fixed for bolt respectively in above-mentioned weak section, ensure that the reliable and stable performance of main contact pedestal, 3, because the wherein side at guide-track groove is provided with resilient clip, greatly facilitate installation personnel and product of the present utility model is installed on guide rail, effectively improve installation effectiveness.
