Abstract
The utility model relates to the field of contactor devices, in particular to a feedback contact structure for a contactor. Comprises a microswitch and a bracket matched with the microswitch for use; the micro switch is arranged above the bracket, and the bracket is fixed at the top end of a linkage rod penetrating through the moving contact through a nut; because the bracket is connected with the linkage rod, the up-and-down movement of the linkage rod can drive the bracket to move up and down, and the micro switch above the bracket is indirectly triggered by the linkage rod.
Description
Technical Field
The utility model relates to the field of contactor devices, in particular to a feedback contact structure for a contactor.
Background
The contactor is applied to electric power, power distribution and power utilization occasions. The contactor is an electric appliance which is used for controlling a load by closing a contact by utilizing a magnetic field generated by current flowing through a coil in industrial electricity;
energy storage contactor generally uses in the energy storage trade, and the energy storage contactor moving contact is inside airtight cavity, and the during operation can't monitor contact operating condition, and monitors through static contact (high pressure) both ends and has the potential safety hazard, and the current energy storage trade needs main contact operating condition's feedback structure to carry out real time monitoring.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a feedback contact structure for a contactor with contact feedback.
The technical scheme of the utility model is as follows:
the contact is with the structure of the feedback contact, including microswitch and cooperating with microswitch to use the support; the micro switch is arranged above the support, and the support is fixed at the top end of a linkage rod penetrating through the moving contact through a nut.
The support comprises a cross rod, two clamping plates are arranged on the bottom surface of the cross rod, and a touch rod is arranged at the end part of the other end of the cross rod.
An extension plate is arranged at the top end of the feeler lever.
The micro switch is arranged on the inner support cover of the contactor.
And a switch contact piece is arranged at the bottom end of the microswitch.
The utility model has the beneficial effects that: because the bracket is connected with the linkage rod, the up-and-down movement of the linkage rod can drive the bracket to move up and down, and the micro switch above the bracket is indirectly triggered by the linkage rod.
Drawings
The foregoing and other objects, features, and advantages of the utility model will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a stent structure according to the present invention;
in the attached drawing, 1 is a microswitch, 2 is a bracket, 3 is a linkage rod, 4 is a cross rod, 5 is a clamping plate, 6 is a contact rod, 7 is an extension plate, 8 is an inner support cover, and 9 is a switch contact piece.
Detailed Description
Referring to fig. 1, the feedback contact structure for the contactor comprises a micro switch and a bracket 2 matched with the micro switch 1; the micro switch is arranged above the support, and the support is fixed at the top end of a linkage rod 3 penetrating through the moving contact through a nut. Because the bracket is connected with the linkage rod, the up-and-down movement of the linkage rod can drive the bracket to move up and down, and the microswitch above the bracket is synchronously touched; when the moving contact and the static contact are closed, the moving contact and the static contact are linked with the microswitch to input a conducting signal; when the moving contact is disconnected with the static contact, the moving contact is linked with the micro switch to input a non-conducting signal.
The support comprises a cross rod 4, two clamping plates 5 are oppositely arranged on the bottom surface of the cross rod, and a touch rod 6 is arranged at the end part of the other end of the cross rod. The two limiting clamping plates are arranged at two sides of the moving contact in a clamping mode in front of and behind each other and are matched with the moving contact to be installed more firmly; a microswitch is arranged above the feeler lever, and the feeler lever moves upwards to abut against the microswitch to close the microswitch.
An extension plate 7 is arranged at the top end of the feeler lever. The extension plate increases the contact area with the micro switch, so that the micro switch is stressed more uniformly, and reliable contact is ensured.
The microswitch is arranged on an inner support cover 8 of the contactor.
And a switch contact plate 9 is arranged at the bottom end of the microswitch. One end of the switch contact piece is closed with the micro switch main body, and the other end of the switch contact piece is disconnected with the micro switch main body, so that the switch contact piece is convenient to be matched with the contact rod for use.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
Claims (5)
