Abstract
A starting safety protection device for a starting motor is characterized in that a temperature controller and a compression spring are arranged on a binding post and between a lug plate and a compression nut, the temperature controller is composed of a bowl-shaped wiring plate and an annular elastic bag arranged in an inner cavity of the wiring plate, a thermosensitive medium with a large thermal expansion coefficient is filled in the elastic bag, and a power line is led out of the wiring plate. The utility model is arranged on an electromagnetic switch of a starting motor, under the normal state, a wiring disc is tightly attached to a wiring lug, a power line is connected, and the starting motor works to start an engine; if the starting is not successful, when the starting motor works for a long time, the temperature rises, the thermosensitive medium expands, the wiring board is pushed open, and the power supply is disconnected, so that the winding and the insulating layer are prevented from being burnt, and the starting motor is automatically protected.
Description
Technical field
The utility model relates to the power line termination of actuating motor, the safety protection device when particularly starting.
Background technique
Because the static resistance of start of motor is very big, actuating motor need be exported high pulling torque in order to overcome the static inertia of motor, drives engine rotation.At this moment the storage battery output current often reaches more than the amperes up to a hundred, and therefore, actuating motor is the performance characteristic design according to short time, big electric current, the slow-speed of revolution, high moment of torsion.The rotor coil of actuating motor is to form with thick flat type copper wire coiling, be applicable to big current work, but long-time excess current can produce high temperature, and can damage storage battery, so the engine start time was limited in 15 seconds, one push start is unsuccessful, to restart after 2～3 minutes at interval, if during continuous three fail to starts, should check and fix a breakdown.But in actual use sometimes because there are the problem of other influence starting in discharged or defective battery or motor itself; the operator who has can not be by this regular operation; but long-time continuous starting; so just easily the too high winding insulation layer that causes of actuating motor temperature rise is burnt, and the termination of existing actuating motor does not have protective action.
The model utility content
The technical problems to be solved in the utility model provides a kind of too high actuating motor start-up safety and protection device that causes the winding insulation layer to burn of actuating motor when starting temperature rise that prevents.
The technical solution of the utility model is: the actuating motor start-up safety and protection device; comprise wiring terminal support, lug plate, wiring terminal and gland nut; improvements are to be provided with temp controller and pressure spring on the wiring terminal between lug plate and gland nut; described temp controller is made of bowl-type patchboard and the ring-type elastic force capsule that is located at the patchboard inner chamber; fill the bigger thermal media of thermal expansion coefficient, extracting power supply cord on the patchboard in the elastic force capsule.
Above-mentioned thermal media is a kind of in ether, alcohol, the paraffin, preferred ether; Behind the elastic force capsule expanded by heating, the gap a of patchboard and lug plate is 0.5～1.5mm.
After loading onto the utility model on the magnetic switch of actuating motor, under the normal condition, patchboard is adjacent to by spring action and lug plate, during short-term operation, connects power switch in short-term, and actuating motor is started working, and motor is started.If fail to start, when the operator connected when repeatedly starting is promptly long by force, the accumulation of lug plate temperature was risen, and when reaching certain value, the thermal media expanded by heating makes the expansion of elastic force capsule, backs down patchboard, deenergization, the unlikely winding insulation layer that burns of protection actuating motor; After temperature descended, thermal media shrank, and patchboard resets under spring pressure again, and power line is connected automatically, and actuating motor recovers normal state.The utility model can prevent that the operator from starting and the accident of the actuating motor that is damaged by force.
Description of drawings
Structural representation when accompanying drawing is the utility model outage.
Embodiment
As figure, wiring terminal support 1, lug plate 2, wiring terminal 7 are installed on the magnetic switch of actuating motor, between lug plate and nut 6, be provided with temp controller and pressure spring 5 on the wiring terminal, temp controller is made of bowl-type patchboard 3 and the ring-shaped rubber capsule 8 that is located at the patchboard inner chamber, be full of ether 9 in the rubber bag tank, extracting power supply cord 4 on the patchboard.When working when long, temperature raises, and ether expands, and rubber bag tank backs down patchboard, and gap a is 1.0mm, and power supply disconnects.Under the normal state, patchboard and lug plate are adjacent to.
Claims (3)
1, a kind of actuating motor start-up safety and protection device; comprise wiring terminal support, lug plate, wiring terminal and gland nut; it is characterized in that between lug plate and gland nut, being provided with temp controller and pressure spring on the wiring terminal; described temp controller is made of bowl-type patchboard and the ring-type elastic force capsule that is located at the patchboard inner chamber; fill the bigger thermal media of thermal expansion coefficient, extracting power supply cord on the patchboard in the elastic force capsule.
2,, it is characterized in that described thermal media is a kind of in ether, alcohol, the paraffin by the described actuating motor start-up safety and protection device of claim 1.
3, by the described actuating motor start-up safety and protection device of claim 2, it is characterized in that elastic force capsule expanded by heating after, the gap a of patchboard and lug plate is 0.5～1.5mm.
