Abstract
The utility model relates to a device for protecting the terminal of a battery. The device has the following structure that the output of a circuit controller is connected with a sucking coil of a relay, a sampling resistor is connected with a normally-closed contact of the relay, the other end of the normally-closed contact is connected with the terminal, and the normally-closed contact is a silver contact. The device not only can protect the battery but also is free of power consumption since the silver contact is near to be zero when the battery runs, thereby being applied to equipment with heavy load current such as the electrically power assisted vehicle, the cropper, the sprayer and the like.
Description
Technical field
The utility model relates to battery, particularly a kind of battery terminal protective device.
Background technology
Before the present utility model, usually employing such as under-voltage, the overload that occurs in the circuit and the short circuit metal-oxide-semiconductor of connecting is used as guard block.But, what now often run into is the occasion that needs big electric current, as Moped Scooter, hay mover etc., obviously metal-oxide-semiconductor is owing to electric current produces meaningless loss through itself producing pressure drop, big electric current can cause misoperation, or need a plurality of metal-oxide-semiconductor parallel connections, but cause more pressure drop loss own.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, develops a kind of battery terminal protective device.
The technical solution of the utility model is:
The battery terminal protective device, sample resistance two ends connecting circuit controller, its major technique is characterised in that circuit controller output succeeds the pull-in winding of electrical equipment, sample resistance connects the normally closed interlock of relay, normally closed interlock other end connecting terminal.
Advantage of the present utility model and effect are not only can protect battery; and when battery operation because the practically negligible and no power waste of silver contact resistance; and can apply in the equipment operation of large load current very, as Moped Scooter, hay mover and sprayer etc.
Other advantage of the present utility model and effect will go on to say below.
Description of drawings
Fig. 1---the utility model structural principle schematic diagram.
Embodiment
As shown in Figure 1:
Battery 1 connects sample resistance 2, sample resistance 2 two ends connecting circuit controllers 3, and the coil 4 of electrical equipment is succeeded in circuit controller 3 outputs, and sample resistance 2 is succeeded the normally closed interlock 5 of electrical equipment, is that terminal 6 two ends and battery 1 form the loop at last.Circuit controller 3 mainly is the controller that under-voltage, overload and short circuit etc. are detected and control, and normally closed interlock 5 is silver contacts, high temperature resistant, high pressure and high electric current.Circuit controller 3 is control circuit module commonly used.
During application:
Power to terminal 6 when battery 1, because terminal 6 is the electrical equipment that Moped Scooter or hay mover or sprayer etc. need big electric current, so big electric current passes through the silver contact of the normally closed interlock 5 of relay, and because resistance is almost nil, so do not produce loss.In case really occur under-voltage or overload or short circuit; then circuit controller 3 sharply changes by the voltage of sample resistance 2, and the coil 4 of control relay is thrown off the silver contact of the normally closed interlock 5 on relay road in the same old way; protection terminal and battery, thus the scope of application and situation enlarged.
Claims (2)
1. battery terminal protective device, sample resistance two ends connecting circuit controller is characterized in that circuit controller output succeeds the pull-in winding of electrical equipment, sample resistance connects the normally closed interlock of relay, normally closed interlock other end connecting terminal.
2. battery terminal protective device according to claim 1 is characterized in that the normally closed interlock of relay adopts silver contact.
