Abstract
The utility model relates to a float switch and belongs to switches. The float switch comprises a wire, a casing, an end cap, and a micro-switch, a lever and a steel ball which are in the casing, wherein the end cap is connected with the casing, the end cap is provided with a wiring hole, the wire penetrates through the wiring hole of the end cap and is electrically connected with the micro-switch, a part of the end cap at a left side of the wiring hole is provided with an inner chamber, the inner chamber is provided with inner thread, the inner chamber is internally provided with a locking rubber ring, a locking screw is screwed on the inner thread, the locking rubber ring and the locking screw are sleeved on the wire, a right end of the locking screw presses against on the locking rubber ring, and a right end of the locking rubber ring presses against on the end cap near the wiring hole. The float switch has advantages of relatively high assembling efficiency, relatively low cost, economical performance and environmental friendliness.
Description
Technical field:
The utility model relates to a kind of switch, is specifically the float switch that pumping for water pump work is controlled in a kind of lifting by the water surface.
Background technology:
Float switch is usually with water pump is used in conjunction with and float on the surface by buoyancy own, it generally comprises electric wire, housing, end cap and the sensitive switch that is positioned at housing, lever and steel ball, end cap is connected with housing, end cap is provided with through wires hole, electric wire is electrically connected to sensitive switch through the through wires hole of end cap, at present, sealing between electric wire and end cap normally adopts the mode of smearing epoxy glue to seal, due to epoxy glue itself, to have setting time long, the shortcomings such as not environmental protection, therefore cause the float switch efficiency of assembling low, it is long to solidify standing time, not environmental protection of assembling process, the shortcomings such as cost is higher.
The utility model content:
The technical problems to be solved in the utility model is, provides a kind of efficiency of assembling higher, and cost is lower, the float switch of economic environmental protection.
Technical solution of the present utility model is, provide a kind of float switch with following structure: comprise electric wire, housing, end cap and the sensitive switch that is positioned at housing, lever and steel ball, end cap is connected with housing, end cap is provided with through wires hole, electric wire is electrically connected to sensitive switch through the through wires hole of end cap, wherein, the end cap that is positioned at the through wires hole left side is provided with inner chamber, inner chamber is provided with internal thread, be provided with the locking rubber ring in inner chamber, be rotary with lock-screw on internal thread, locking rubber ring and lock-screw all are enclosed within on electric wire, the lock-screw right-hand member withstands on the locking rubber ring, locking rubber ring right-hand member withstands on the end cap at through wires hole place.
After adopting above structure, compared with prior art, the utility model float switch has the following advantages: from adopting the mode of smearing epoxy glue between electric wire in prior art and end cap, seal different, because the end cap of the utility model float switch is provided with inner chamber, inner chamber is provided with internal thread, be provided with the locking rubber ring in inner chamber, be rotary with lock-screw on internal thread, locking rubber ring and lock-screw all are enclosed within on electric wire, the lock-screw right-hand member withstands on the locking rubber ring, locking rubber ring right-hand member withstands on the end cap at through wires hole place, in the process of the utility model float switch assembling, only need to screw screw, distortion by the locking rubber ring just can realize the sealing between electric wire and end cap, do not need to use epoxy glue, saved solidifying standing time of epoxy glue, therefore, the utility model float switch efficiency of assembling is higher, cost is lower, economic environmental protection.
The accompanying drawing explanation:
Fig. 1 is that the master of the utility model float switch looks the sectional structure schematic diagram;
Fig. 2 is the sectional structure schematic diagram of " A-A " in Fig. 1.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model float switch is described in further detail:
As depicted in figs. 1 and 2, in this embodiment, the utility model float switch comprises electric wire 1, housing 7, end cap 4 and the sensitive switch 8 that is positioned at housing 7, lever 6 and steel ball 5, end cap 4 is connected with housing 7, end cap 4 is provided with through wires hole 12, electric wire 1 is electrically connected to sensitive switch 8 through the through wires hole 12 of end cap 4, the end cap 4 that is positioned at through wires hole 12 left sides is provided with inner chamber 11, inner chamber 11 is provided with internal thread 10, be provided with locking rubber ring 2 in inner chamber 11, be rotary with lock-screw 3 on internal thread 10, locking rubber ring 2 and lock-screw 3 all are enclosed within on electric wire 1, lock-screw 3 right-hand members withstand on locking rubber ring 2, locking rubber ring 2 right-hand members withstand on the end cap 4 at through wires hole 12 places, be provided with pad 9 between lock-screw 3 and locking rubber ring 2.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection range of the utility model claims.
