Abstract
The invention discloses a 3V lithium battery. A battery cell is installed in a first battery cavity; a supporting frame is installed in a second battery cavity; one end of a plastic casing is provided with a positive pole hole and a negative pole hole; a positive pole terminal of the battery cell is adjacent to the positive pole hole; the position on the second battery cavity adjacent to the negative pole hole is provided with an auxiliary negative pole plate; the auxiliary negative pole plate is positioned on the lower end of the supporting frame; the auxiliary negative pole plate is connected with a negative pole terminal of the battery cell through a connecting wire; and the connecting wire penetrates through the inside of the supporting frame. The invention has the following advantages: the supporting frame is substituted for the traditional unit battery, thereby preventing the plastic casing from recess or deformation under an applied force; the auxiliary negative pole plate is used as the negative pole terminal of the second unit battery to be matched with a battery interface of an electric apparatus; and the auxiliary negative pole plate is connected with the negative pole terminal of the battery cell through the connecting wire. Under the conditions of adopting the traditional plastic casing, one CR17335 battery cell installed inside can satisfy the 3V power supply voltage of the electric apparatus.
Description
Technical field
The present invention relates to a kind of lithium battery, especially relate to a kind of 3V lithium battery.
Background technology
Lithium battery is mainly used in the electrical appliance fields that capacity required is large, the storage time is long, operating temperature range is wide such as camera, cigarette sense siren, gas meter, ammeter, water meter, the structure of traditional CR-P2 lithium battery comprises plastic casing and two batteries, and CR-P2 lithium battery voltage is 6V.Cell without the packing insulation is called " plain battery ", and the negative pole sidewall of plain battery is in naked state.Along with developing rapidly of electronic technology, each chip and the peripheral circuit of electric equipment are more and more energy-conservation, and much the supply power voltage of electric equipment newly developed reduces to present 3V by original 6V.And because the unified standard of the battery mounting interface of electric equipment is also upgraded in time, therefore present 6V CR-P2 lithium battery has been not suitable for new electric equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of overall dimension is identical with the CR-P2 lithium battery, voltage is the lithium battery of 3V.
the present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of 3V lithium battery, comprise plastic casing and a plain battery of joint, have two battery cavities in described plastic casing, be respectively the first battery cavities and the second battery cavities, the element battery is arranged in the first battery cavities, in the second battery cavities, bracing frame is installed, one end of described plastic casing is provided with anodal hole and negative pole hole, the positive terminal of element battery is near anodal hole, the place, close negative pole hole of the second battery cavities arranges auxiliary negative plate, auxiliary negative plate is positioned at the lower end of bracing frame, auxiliary negative plate is connected with the negative pole end of plain battery by connecting line, it is inner that described connecting line passes described bracing frame.
Described bracing frame is the tubular bracing frame, and the inwall of the outer wall of described tubular bracing frame and the second battery cavities is close to.Prevent plastic casing indent or distortion under external force.
Described connecting line is the hard connecting line, described hard connecting line becomes inverted L shape, the upper transverse part front end of inverted L shape hard connecting line is fixedly connected with nickel strap, the negative pole end welding of described nickel strap and plain battery, the lower end, vertical part of described inverted L shape hard connecting line and the welding of auxiliary negative plate.The hard connecting line can be strengthened the support strength in bracing frame, and the overall structure of lithium battery is strengthened.
Described plastic casing comprises cylindrical case and vinyl cover, passes through the ultrasonic drilling machine welding between described cylindrical case and described vinyl cover.The assembling of lithium battery is convenient.
The tubular bracing frame is plastic tube, can prevent the short circuit of plain battery.
Plain battery and the component weight in the second battery cavities in the first battery cavities equate, make the weight ratio of lithium battery interior more balanced, in the electric equipment use procedure, have more stable power supply performance.
Compared with prior art, advantage of the present invention is that bracing frame substitutes traditional cell, prevent plastic casing indent or generation deformation under external force, auxiliary negative plate serves as the negative pole end of the second traditional cell, be complementary with the battery interface of electric equipment, auxiliary negative plate is connected with the negative pole end of plain battery by connecting line.Adopting under traditional plastic casing condition, a joint CR17335 battery is only installed in inside, can satisfy the 3V supply power voltage of electric equipment.
