Abstract
The utility model discloses a self-protecting temperature and current protector for a chargeable battery, which includes a shell body; an active contact leaf, a static contact leaf, and an insulated isolation bracket which are arranged in the shell; and a lead which is led out from the outer end of the shell body. A port at one end of the metal shell body is obturated by insulating material. Corresponding contact points are respectively arranged on the active contact leaf and the static contact leaf, and the active contact leaf and the static contact leaf contact each other by the contact points, and a heat generator is directly or indirectly arranged between the active contact leaf and the static contact leaf. When the charger is electrified, the active contact leaf jumps, the current flows through the heat generator arranged between the active and the static contact leaves to cause that the active and the static contact leaves keep opened. Only when the plug of the power supply is pulled out and the power supply is broken completely, along with the decline of the temperature, the active and the static contact leaves can contact each other. The self-protecting temperature and current protector improves the safety of the protected electric appliance greatly.
Description
Technical field
The utility model relates to a kind of rechargeable battery self-insurance's temperature current protector.
Background technology
The original temperature current protector is connected in the circuit of protected electrical equipment, and in the charging circuit as rechargeable battery, electric current is exported by lead through lead, movable contact spring, contact, static contact again.When ambient temperature reaches the specified take-off temperature value of movable contact spring or the electric current by protector and makes the temperature of movable contact spring be increased to specified take-off temperature value; the movable contact spring take-off is cut off the electricity supply, and shielded electrical equipment is no longer worked; avoid damaging, play the purpose of protection electrical equipment because of continuing to heat up.When the controller ambient temperature dropped to predetermined temperature value, movable contact spring resetted, automatically energized.
The original temperature current protector comprises housing; be provided with the insulation isolation mount in the housing; the rack body center offers the movable contact spring jack; prop up top of the trellis and be provided with the static contact mounting groove; movable contact spring and static contact are fixedly mounted in the housing by support, and active and static contact disconnects the back along with temperature reduction meeting resets very soon.
The utility model content
The utility model technical issues that need to address just are to overcome original rechargeable battery temperature current protector and have the defective that resets very soon after the disconnection; a kind of rechargeable battery self-insurance's temperature current protector is provided, and it installs a heater between movable contact spring and static contact.When energized, the sound sheet is by contacting, and heater does not almost have electric current to pass through, and heater does not generate heat.Make the movable contact spring take-off when the battery charge abundance makes the overheated or unexpected big electric current of battery, the sound contact is disconnected, at this moment electric current just generates heat by heater, and makes the sound sheet keep off-state continuously.Have only power supply pulled out (deenergization) after, the sound sheet resets owing to temperature descends, and connects by contact, can continue to use again.This self-insurance's battery temperature protector has self-insurance to continue break function after disconnection; have only after power supply pulls out and just can reset; when being caused danger at the excessive or overheated overcurrent of electrical appliance of charging, battery keeps continuing to cut off electric current; until pulling out power supply (deenergization); more safer than original protector, improved the fail safe of rechargeable battery with the temperature current protector.
For addressing the above problem, the technical solution of the utility model is:
The utility model self-insurance temperature current protector; comprise housing; be arranged on the movable contact spring in the housing; static contact; the insulation isolation mount and draw the housing outer end and movable contact spring; the lead that static contact connects; metal shell is drawn the port insulating material sealing of lead one end; described insulation isolation mount body center offers the movable contact spring jack; movable contact spring fixedly is inserted in the movable contact spring jack; prop up top of the trellis and be provided with the static contact mounting groove; static contact is fixedly mounted in the static contact mounting groove; movable contact spring; be respectively arranged with the contact of mutual correspondence on the static contact; movable contact spring touches mutually by constant temperature point with the static contact contact and closes; directly be provided with a heater between described movable contact spring and the static contact, or by the housing metal medium heater be set between active and static contact indirectly.
Arching upward in the static contact described in the utility model forms a spill cambered surface, makes static contact and movable contact spring keep balance like this.So in use, after variations in temperature, owing to being parallel surface between two sheet metals, the contact contact-making surface is parallel, and the deviation of final mean annual increment movement is minimum, has improved the stability of temperature current protector.
For fixed support stably, make active and static contact and housing keeping parallelism, install on two relative sides with support at housing and be symmetrical arranged a groove that caves inward respectively, movable contact spring just can not be oblique and contact housing like this.Can not install simultaneously yet and excessively enter the possibility that the back takes place to contact with the housing top.
The utility model is by directly or indirectly installing a heater between still and moving plate, when the charger energized, battery begins charging, overcharges after the battery abundance to generate heat, and makes the movable contact spring take-off, disconnect charging current, at this moment electric current makes dynamic and static contact continue to keep off-state by the heater heating that is installed between the dynamic and static contact, has only when pulling out attaching plug, all behind the deenergization, along with temperature descends, movable contact spring and static contact just can be run into together.Improved the fail safe of temperature current protector greatly.And slightly inwardly the static contact of arch keeps the plan-parallel structure between movable contact spring and the static contact; in practical process, be parallel surface between two sheet metals like this, the contact contact-making surface is also parallel; minimum because of the offset deviation of variations in temperature, improved temperature current protector stability.
The utility model is by being arranged on two corresponding grooves of housing both sides, be used for fixing the insulation isolation mount that stretches in the housing, the installation site that guarantees the insulation isolation mount is fixed, moving plate and housing keeping parallelism and guarantee to make moving plate and housing short circuit just in case isolation mount is offset.Especially can not be to the housing bottom displacement, moving plate and still and housing bottom have kept certain clearance like this, cause short circuit at the bottom of the anti-locking plate contact shell.Reach the purpose of safe handling.
