Abstract
The utility model relates to an approach switch, which comprises a cylindrical shell, a magnetic core arranged in the shell, a circuit board, and a coil wound on the magnetic core, wherein one end surface of the sell is an induction surface. The approach switch further comprises an output cable connected with the circuit board and an indicator lamp, wherein the coil is connected with the circuit board, the side wall of the shell is provided with external threads, the side wall of the shell is sheathed with two positioning nuts, and the two positioning nuts are matched with the external threads on the side wall of the shell. The utility model provides the approach switch adopting the above technical scheme. The approach switch is convenient to install, and the installation fastness of the approach switch can be ensured after the approach switch is used for a long time.
Description
Technical field
The utility model relates to a kind of near switch.
Background technology
Near switch is a kind ofly need not carry out Mechanical Contact and manipulable position switch with moving component; When object near the sensitive surface of switch during to operating distance; Do not need Mechanical Contact and apply any pressure to make its switch motion, exchange or dc electric apparatus thereby drive.
At present, existing a kind of near switch, generally comprise shell cylindraceous, in the enclosure magnetic core, circuit board, the coil of winding on magnetic core are set; Shell one end face is a sensitive surface, also includes the output cable and the indicator light that are connected with circuit board, and coil is connected with circuit board; With this structure be installed on the electrical equipment near switch the time, earlier on electrical equipment, offer through hole, will be fixedly connected with through-hole wall near the switch sidewall through fixing glue again; But; If long-time the use, the stickiness of fixing glue descends, thereby feasible fixing not firm near switch.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of prior art, it is a kind of near switch that the utility model provides, and it is easy for installation, the long-time use, and it is firm still to guarantee to install near switch.
The technical scheme of the utility model: a kind of near switch; Include shell cylindraceous, in the enclosure magnetic core, circuit board, the coil of winding on magnetic core are set, shell one end face is a sensitive surface, also includes the output cable and the indicator light that are connected with circuit board; Coil is connected with circuit board; It is characterized in that: described side wall of outer shell is provided with external screw thread, is arranged with two setscrew nuts on the described side wall of outer shell, and the external screw thread on described two setscrew nuts and the side wall of outer shell is complementary.
Adopt technique scheme, when installing, only need and to pass the through hole on the electrical equipment near switch one end near switch; Two setscrew nuts lay respectively at the both ends of the surface of through hole; Then two setscrew nuts are tightened each other, this structure near switch, it is easy for installation; The long-time use, it is firm still to guarantee to install near switch.
The further setting of the utility model: also be provided with the ring-type locating shim between described two setscrew nuts.
Adopt above-mentioned further setting, the ring-type locating shim is set can be so that more firm near the switch installation.
Further being provided with again of the utility model: described ring-type locating shim is provided with two; The inner ring of described two ring-type locating shims some tongue pieces that extended internally; Described tongue piece is the arcuation setting; Described tongue piece inner face aligns with two ring-type locating shim opposing end faces, and the outer face of tongue piece extends to outside the opposing end face of two ring-type locating shims.
Adopt above-mentioned further setting again; The corresponding two setscrew nut settings respectively of two ring-type locating shims; Two ring-type locating shims lay respectively on the both ends of the surface of through hole, because tongue piece is the arcuation setting, when two setscrew nuts are tightened; Tongue piece can prevent that two setscrew nuts from skidding, thereby has further improved the fixing of installing near switch.
