Abstract
The utility model relates to a be applied to protection device on change over switch, change over switch includes casing and circuit board, the casing is the rectangle casing, be equipped with four closed angle limits on the rectangle casing, the closed angle edge is equipped with a plurality of protection device, protection device through a connecting piece swing joint on the closed angle limit, protection device is the rubber protective sheath, the shape of rubber protective sheath and closed angle limit looks adaptation. Protection device protects four closed angles that have sharp -pointed angle on the rectangle casing, and protection closed angle that can be fine is not damaged, can prevent in addition that the closed angle from damaging the other part, and protection device sets up to the rubber protective sheath, has both reached the technological effect of protection closed angle, and the volume of protective sheath is less in addition, can not increase too many volume for change over switch.
Description
Technical field
The utility model relates to a kind of device of the change over switch be applied on circuit, and especially a kind of structure is simple, can protect the protective device of the housing on change over switch.
Background technology
Change over switch be a kind of for two-way or two-way with the device for switching of power source or load transfer.Change over switch is formed by more piece contact combinations, in the electrical apparatus, is used for non-frequently and connects and point deenergizing, switch on power and load, the rotating of measurement three-phase voltage and control low capacity asynchronous motor and star delta starting etc.These parts are fastened by bolts as a whole.Existing change over switch generally includes housing and wiring board, housing is by carrying out clamping with the shackle member on wiring board, but switch is in transport and installation process, due to housing employing is rectangular box, so, the sharp corner of housing just easily suffers damage or damages miscellaneous part, and make in use, the useful life of change over switch will reduce.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of device of the change over switch be applied on circuit, and especially a kind of structure is simple, can protect the protective device of the housing on change over switch.
For solving the problems of the technologies described above; the utility model comprises housing and wiring board; described housing is rectangular housing; described rectangular housing is provided with four wedge angle limits; described wedge angle limit is provided with several protective devices; described protective device is movably connected on wedge angle limit by a connection piece, and described protective device is rubber protecting jacket, and shape and the wedge angle limit of described rubber protecting jacket are suitable.
After have employed said structure; four wedge angles with sharp angles in rectangular housing protected by protective device; wedge angle can well be protected not damaged; and can prevent wedge angle from damaging miscellaneous part; and protective device is set to rubber protecting jacket; both the technique effect of protection wedge angle had been reached, and the small volume of protective sleeve, too many volume can not be increased to change over switch.
As further improvement of the utility model, described housing side is provided with protective sleeve mounting groove near two ends, wedge angle limit, and protective sleeve mounting groove and the wedge angle limit at described two ends form protective sleeve shallow storage space jointly, and connector is located in this protective sleeve shallow storage space.
After have employed said structure, protective sleeve can well be arranged on this mounting groove by the setting of protective sleeve mounting groove, so both can not increase this body length of housing, also serve the position-limiting action to protective sleeve.
As further improvement of the utility model; described connector is be fixedly arranged on the slipmat on the protective sleeve mounting groove of both sides respectively; shape and the protective sleeve mounting groove of described slipmat are suitable; described slipmat and rubber protecting jacket are worked in coordination, and described rubber protecting jacket can be close in slipmat.
After have employed said structure; connector is the slipmat be fixedly arranged on mounting groove; link has in the past been abandoned in such setting; such as clamping and being threaded; and protective sleeve is elastomeric material; can well be resisted against in slipmat, play the technique effect of difficult drop-off, nor volume own can be increased.
Accompanying drawing explanation
figure 1 shows that protective device is arranged at the front view in change over switch;
figure 2 shows that protective device internal structure schematic diagram.
Embodiment
As shown in Figure 1; for solving the problems of the technologies described above; switch comprises housing 1 and wiring board 2; described housing 1 is rectangular housing; described rectangular housing is provided with four wedge angle limits, and described wedge angle limit is provided with several protective devices 3, and described protective device 3 is movably connected on wedge angle limit by a connection piece; described protective device 3 is rubber protecting jacket, and shape and the wedge angle limit of described rubber protecting jacket are suitable.Four wedge angles with sharp angles in rectangular housing protected by protective device 3; wedge angle can well be protected not damaged; and can prevent wedge angle from damaging miscellaneous part; and protective device is set to rubber protecting jacket; both the technique effect of protection wedge angle had been reached; and the small volume of protective sleeve, too many volume can not be increased to change over switch.
As shown in Figure 2, described housing side is provided with protective sleeve mounting groove 4 near two ends, wedge angle limit, and protective sleeve mounting groove 4 and the wedge angle limit at described two ends form protective sleeve shallow storage space jointly, and connector is located in this protective sleeve shallow storage space.Protective sleeve can well be arranged on this mounting groove by the setting of protective sleeve mounting groove 4, so both can not increase this body length of housing, also serve the position-limiting action to protective sleeve.Described connector is be fixedly arranged on the slipmat 5 on the protective sleeve mounting groove of both sides respectively, and shape and the mounting groove 4 of described slipmat 5 are suitable, and described slipmat 5 is worked in coordination with rubber protecting jacket, and described rubber protecting jacket can be close in slipmat 5.Connector is the slipmat 5 be fixedly arranged on mounting groove, arranges like this and has abandoned link in the past, such as clamping and being threaded; and protective sleeve is elastomeric material; can well be resisted against in slipmat 5, play the technique effect of difficult drop-off, nor can this health be increased.
