The performance of limit switch moistureproof and waterproof.
Technical solution of the present utility model is：
A kind of waterproof sealing structure of contact limit switch, wherein, it includes a limit switch, and the limit switch is set
There is a switch housing, the switch housing is provided with switch cover, and the side of the switch housing is provided with threading opening, in the threading opening
It is equipped with pre-fabricated electric cables, the pre-fabricated electric cables in the limit switch with binding post in being connected；The switch housing and switch cover
Fluid sealant is filled with the cavity of formation.
The waterproof sealing structure of contact limit switch as described above, wherein, opened in the limit switch provided with fine motion
Contact is closed, the fluid sealant corresponds to the microswitch contact and is provided with resigning hole.
The waterproof sealing structure of contact limit switch as described above, wherein, the 4* of a length of 500mm of pre-fabricated electric cables
1.0 computer cable.
The waterproof sealing structure of contact limit switch as described above, wherein, the switch cover and the switch housing
Between be provided with fluid sealant.
The waterproof sealing structure of contact limit switch as described above, wherein, the fluid sealant is 5871 flat seals
Glue.
Learnt by described above, the utility model compared with prior art, can reach the effect of following really：
The waterproof sealing structure of contact limit switch of the present utility model, by wearing pre-fabricated electric cables in limit switch
Afterwards, fluid sealant is filled with inside threading opening and limit switch, so as to reach the performance of lifting limit switch for vertical moistureproof and waterproof.It can reach
To following effect：1st, operating method is simple, and improvement cost is low；2nd, the waterproof and dampproof performance and switch of limit switch are substantially increased
Reliability of Microprocessor；3rd, used in the environment of moist easily immersion, improved limit switch service life is at least prolonged before relatively transforming
It is long 3 years.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Main element label declaration：
The utility model：
1：Microswitch 2：Switch housing 3：Switch cover
4：Binding post 5：The threading opening of pre-fabricated electric cables 6

Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, now control illustrates
Specific embodiment of the present utility model.
The waterproof sealing structure of contact limit switch of the present utility model, in its preferred embodiment, refer to Fig. 1 institutes
Show, pass through the fixation and sealing of fluid sealant 7 and pre-fabricated electric cables 5 so that threading opening 6 is difficult to make moist into water, improves limit switch
Moistureproof and waterproof ability.A kind of waterproof sealing structure of contact limit switch of the present utility model, it includes a limit switch,
The limit switch is provided with switch housing 2, and the switch housing 2 is provided with switch cover 3, and the side of the switch housing 2 is provided with
Threading opening 6, is equipped with pre-fabricated electric cables 5 in the threading opening 6, and the pre-fabricated electric cables 5 in the limit switch with binding post 4 in connecting
Connect；Fluid sealant 7 is filled with the cavity that the switch housing 2 and switch cover 3 are formed.Wherein, first pre-fabricated electric cables 5 are fed through
Line mouth 6, pre-fabricated electric cables 5 are connected with binding post 4, by the way that fluid sealant 7 is injected into inside threading opening 6 and limit switch, and it is complete
The gap of full closure threading opening 6.
The waterproof sealing structure of contact limit switch of the present utility model as described above, in its preferred embodiment,
The contact of microswitch 1 is provided with the limit switch, the corresponding contact of microswitch 1 of the fluid sealant 7 is provided with resigning hole.When

The waterproof sealing structure of contact limit switch of the present utility model as described above, in its preferred embodiment
In, fluid sealant 7 is provided between the switch cover 3 and the switch housing 2.Using fluid sealant 7 by switch cover 3 and switch housing 2
It is connected and sealed, further improves the sealing effectiveness of limit switch.
The waterproof sealing structure of contact limit switch of the present utility model as described above, in its preferred embodiment,
The fluid sealant 7 is 5871 flat sealants.
The waterproof sealing structure of contact limit switch of the present utility model, by wearing pre-fabricated electric cables 5 in limit switch
Afterwards, fluid sealant is filled with inside threading opening 6 and limit switch, so as to reach the performance of lifting limit switch for vertical moistureproof and waterproof.Energy
Reach following effect：1st, operating method is simple, and improvement cost is low；2nd, substantially increase the waterproof and dampproof performance of limit switch and open
Close Reliability of Microprocessor；3rd, used in the environment of moist easily immersion, before the relatively transformation of improved limit switch service life at least
