Abstract
The utility model provides an underwater travel switch, which comprises a microswitch, a hollow shell with one end being provided with an opening and a side wall being provided with a notch, a cover covering on the opening, and a cable, wherein the microswitch comprises a main case, a contact movement system arranged in the main case, an electrical connection end and a push rod; the hollow shell is provided with an inner cavity; the microswitch is put in the inner cavity; the push rod is partially exposed out of the shell; one end of the cable penetrates through the notch and is connected with the electrical connection end; a seal ring is arranged on a connecting part of the push rod and the shell; and glue is filled in the inner cavity and is used for covering a connecting part of the cable and the electrical connection end. The glue is filled in the inner cavity is used for covering the connecting part of the cable and the electrical connection end, so that the microswitch is effectively prevented from water leakage, and the reliability of underwater operation of the travel switch is improved; and simultaneously, water-proof devices are simplified, and the cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of Underwater limit switch.
Background technology
The travel switch that mechanical transmission mechanism in the underwater work system is used requires water proof type or submerged type.National patent number is a kind of Underwater limit switch of 93242474, the hollow housing that comprise sensitive switch, have an end opening, sidewall is provided with breach, with lid and cable that opening makes up, sensitive switch comprises the body casing; Be arranged at the contact kinematic system in the body casing, electrical connection terminal and push rod, hollow housing has inner chamber; Sensitive switch is positioned in the inner chamber; Pusher section is exposed to outside the housing, is provided with sealing ring in indentation, there, is connected with guide pin bushing at push rod arranged outside bellows.Though this Underwater limit switch has had certain water resistance, its structure is comparatively complicated, and cost is higher.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of good airproof performance is provided, the Underwater limit switch that reliability is high.
Be to realize above-mentioned purpose, the utility model adopts a kind of like this Underwater limit switch, the hollow housing that comprise sensitive switch, have an end opening, sidewall is provided with breach, the lid and the cable that make up with described opening; Described sensitive switch comprises the body casing, is arranged at the contact kinematic system in the described body casing, electrical connection terminal and push rod; Described hollow housing has inner chamber; Described sensitive switch is positioned in the described inner chamber, and described pusher section is exposed to outside the described housing, and an end of described cable passes described breach; Be connected with described electrical connection terminal; Described push rod and described housing intersection are provided with sealing ring, potting compound in described inner chamber, and described glue is covered the junction of described cable and described electrical connection terminal.
Especially, described push rod is provided with sheath outward, and described sheath and described housing intersection are provided with sealing ring.
The difference of the utility model and prior art is: through the junction that encapsulating in inner chamber is covered cable and electrical connection terminal, prevent that effectively sensitive switch from leaking, improved the reliability that travel switch is worked under water; Simultaneously also simplified the waterproof device, reduced cost greatly.
