Abstract
The utility model discloses an easily assembled cam switch. The cam switch comprises one or a plurality of contact boxes (1), a front baffle (2), a rear baffle (3) and a rotation shaft (4) and is characterized in that one or a plurality of fixing devices for accommodating magnetic quenching devices are arranged in the contact boxes (1); each contact box (1) consists of a mounting hole (5) and a positioning post (6); and the positioning posts have characteristics of elastic deformation, are platy or columnar or have other shapes in which the magnetic quenching devices can be clamped. The easily assembled cam switch has the advantages that structures such as wire pressing frames, screws and springs are not required, and a male pre-insulating joint, a female pre-insulating joint or a wiring device is directly used for wiring, so that the assembly efficiency is greatly improved, and a large amount of wiring time is saved.
Description
Technical field
The utility model relates to the device for switching used in a kind of electric device, is specifically related to a kind of cam switch for electric control loop.
Background technology
Automatically control and field of power electronics in, cam switch is widely used in break-make and the switching controls of various circuit, along with the continuous lifting of electrification requirement, the modularization of cam switch, standardized requirement are more and more higher.Existing cam switch arranges magnetic-quenching arc-extinguishing device in a side of moving contact or fixed contact, to stablize effective cut-out electric current.Current magnetic-quenching arc-extinguishing device is very high to technological requirement, and required magnet and contact box require error very little, and complex installation process, the phenomenon that magnetic-quenching arc-extinguishing device comes off easily occurs, and affect the cam switch overall performance, and reliability and fail safe are all not high.
The utility model content
For above-mentioned deficiency, the utility model provides a kind of cam switch that is easy to assembling.
The utility model is to realize by such technical scheme:
A kind of cam switch that is easy to assembling, comprise one or more contact boxs 1, front apron 2, backboard 3 and rotating shaft 4, it is characterized in that: be provided with the fixture of placing magnetic-quenching arc-extinguishing device in described contact box 1.
Described fixture comprises installing hole 5 and reference column 6, and can have one or more.
Location is lived 6 and is had elastic deformation, and to live 6 can be that sheet or column or other can tighten the shape of magnetic-quenching arc-extinguishing device in location.
The beneficial effects of the utility model are: owing to having adopted said structure, be that the cam switch that is easy to assembling that the utility model provides has reduced the producting process difficulty to contact box, greatly promoted the set-up time, magnetic-quenching arc-extinguishing device difficult drop-off after installation, promoted reliability and the fail safe of the cam switch that is easy to assembling.
The accompanying drawing explanation
Fig. 1 is the overall structure figure that is easy to the cam switch of assembling in the utility model embodiment.
Fig. 2 is the contact box structure figure that is easy to the cam switch of assembling shown in Fig. 1.
Embodiment
In order more to be expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection range of the present utility model is not limited in following examples.
As depicted in figs. 1 and 2, a kind of cam switch that is easy to assembling, comprise one or more contact boxs 1, front apron 2, backboard 3 and rotating shaft 4, it is characterized in that: be provided with the fixture of placing magnetic-quenching arc-extinguishing device in described contact box 1.
As shown in Figure 2, described fixture comprises installing hole 5 and reference column 6, and can have one or more.Location is lived 6 and is had elastic deformation, and to live 6 can be that sheet or column or other can tighten the shape of magnetic-quenching arc-extinguishing device in location.
