Abstract
The utility model is related to safety protection switch technical fields; specifically disclose a kind of waterproof position limit switch; including Switch main body, grounding reed and triple core cable; the grounding reed is inlaid on the inside of the shell of the Switch main body; described triple core cable one end is fixed in the Switch main body; ground wire in the other end is connect with the grounding reed, and in addition two cables stretch out the Switch main body.The utility model waterproof position limit switch, in the embedded dress grounding reed of switch case, it will be grounded on reed connected directly to the grounded, ground wire is set to can be achieved with grounding function without being installed on the outside of Switch main body, not only it had saved electric wire but also had improved the water resistance of switch, and realized the effect that the earthing mode of intracavitary in switch remains to keep waterproofing grade IP68.
Description
Technical field
The utility model belongs to safety protection switch technical field, specifically a kind of waterproof position limit switch.
Background technology
Travel switch, one kind of position switch (also known as limit switch), is a kind of common low current master control electrical apparatus.It utilizes
The collision of manufacturing machine moving component makes its contact action to realize connection or disjunction control circuit, reaches certain control mesh
's.In general, this kind of switch is used to position or the stroke of limit mechanical movement, keep movable machinery automatic by certain position or stroke
Stopping, counter motion, variable motion or automatic back and forth movement etc..In the prior art, the earthing mode of this trip switch is all
Using ground wire circumscribed, not only need to use a large amount of electric wire, but also the waterproofing grade switched is also relatively low.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of waterproof stroke and open
It closes, the interior intracavitary in Switch main body is arranged in ground wire, electric wire had not only been saved but also had improved the waterproofing grade of switch.
In order to solve the above technical problems, the utility model provides a kind of waterproof position limit switch, including Switch main body, ground connection
Reed and triple core cable, the grounding reed are inlaid on the inside of the shell of the Switch main body, described triple core cable one end
It is fixed in the Switch main body, the ground wire in the other end is connect with the grounding reed, and in addition two cables stretch out institute
State Switch main body.
Further, grounding reed injection molding together with the shell of the Switch main body.
Preferably, the ground wire is welded to connect with the grounding reed.
Specifically, the grounding reed is copper sheet.
The utility model has the beneficial effects that：The utility model waterproof position limit switch, in embedded attaching the spring of switch case
Piece will be grounded on reed connected directly to the grounded, and ground wire is made to can be achieved with ground connection work(without being installed on the outside of Switch main body
Can, it had not only saved electric wire but also had improved the water resistance of switch, and realized the earthing mode of intracavitary in switch and remain to keep anti-
The effect of water grade IP68.
Description of the drawings
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the structural schematic diagram of this practicality waterproof position limit switch.
In figure：1- Switch main bodies, 2- grounding reeds, 3- triple core cables, 31- ground wires.
Specific implementation mode
Below in conjunction with Figure of description, the technical scheme in the embodiment of the utility model is clearly and completely retouched
It states, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this
Embodiment in utility model, those of ordinary skill in the art are obtained all under the premise of not making creative work
Other embodiment shall fall within the protection scope of the present invention.
In specific embodiment of the utility model, as shown in Figure 1, the utility model specifically discloses a kind of waterproof strokes
Switch, including Switch main body 1, grounding reed 2 and triple core cable 3, the grounding reed 2 are inlaid in the Switch main body 1
On the inside of shell, the grounding reed 2 is copper sheet；The injection molding together with the shell of the Switch main body 1 of the grounding reed 2；
3 one end of the triple core cable is fixed in the Switch main body 1, and the ground wire 31 in the other end connects with the grounding reed 2
It connects, the ground wire 31 is welded to connect with the grounding reed 2；Other two cables stretch out the Switch main body 1.Make stroke
Ground wire 31 is set up directly in Switch main body 1 by switch while realizing three core wire functions, can still improve switch
Waterproofing grade.
The utility model has the beneficial effects that：The utility model waterproof position limit switch, in embedded attaching the spring of switch case
Piece will be grounded on reed connected directly to the grounded, and ground wire is made to can be achieved with ground connection work(without being installed on the outside of Switch main body
Can, it had not only saved electric wire but also had improved the water resistance of switch, and realized the earthing mode of intracavitary in switch and remain to keep anti-
The effect of water grade IP68.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
