Abstract
The invention discloses a 3V lithium battery which is characterized by comprising a plastic casing and a battery cell, wherein two battery cavities, which are respectively a first battery cavity and a second battery cavity, are arranged in the plastic casing; the battery cell is installed in the first battery cavity; a conductive columnar supporting frame is installed in the second battery cavity; one end of the 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 lower end of the columnar supporting frame is adjacent to the negative pole hole; and a negative pole terminal of the battery cell is connected with the upper end of the columnar supporting frame through a nickel strap in a spot welding mode. The invention has the following advantages: the columnar supporting frame is substituted for the traditional unit battery, thereby preventing the plastic casing from recess or deformation under an applied force. 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 packaging 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 of electric equipment and peripheral circuit more and more energy-conservation, the supply power voltage of electric equipment much newly developed reduces to current 3V by original 6V.And also upgraded in time due to the unified standard of the battery mounting interface of electric equipment, therefore current 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 CR-P2 lithium battery, voltage is the lithium battery of 3V.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of 3V lithium battery, comprise plastic casing and the plain battery of a joint, there are in described plastic casing two battery cavities, be respectively the first battery cavities and the second battery cavities, described plain battery is arranged in the first battery cavities, conductive columnar stays frame is installed in the second battery cavities, one end of described plastic casing is provided with positive pole hole and negative pole hole, the positive terminal of described plain battery is near positive pole hole, the lower end of described columnar stays frame is near negative pole hole, the negative pole end of described plain battery connects by the upper extreme point of nickel strap and described columnar stays frame is soldered.
Be provided with interlayer insulating layer between the first described battery cavities and the second described battery cavities, the short circuit of plain battery can be prevented.
A side of described columnar stays frame is cambered surface sidewall, and columnar stays frame is flat sidewall towards the one side of interlayer insulating layer, and described cambered surface sidewall and the inwall of the second battery cavities are close to, and described flat sidewall and described interlayer insulating layer are close to.Prevent plastic casing indent or distortion under external force.
Described columnar stays frame comprises upper backup pad, lower supporting plate and pillar, described upper backup pad is connected with described lower supporting plate by pillar, described upper backup pad is arranged on the upper end of described pillar, described lower supporting plate is near described negative pole hole, described pillar is be interconnected by the side of three pieces of support plates the triangular prism formed, upper backup pad is identical with the structure of lower supporting plate, described upper backup pad comprises most of arc limit and a straight flange, described arc limit and the inwall of the second battery cavities are close to, and described straight flange and described interlayer insulating layer are close to.Prevent plastic casing indent or distortion under external force.
Described plastic casing comprises tubular plastic shell and vinyl cover, by ultrasonic drilling machine welding between described tubular plastic shell and described vinyl cover.The assembling of lithium battery is convenient.
Plain battery in the first described battery cavities is equal with the component weight in the second battery cavities, makes the weight ratio of lithium battery interior more balanced, in electric equipment use procedure, has more stable power supply performance.
Compared with prior art, advantage of the present invention is that columnar stays frame substitutes traditional cell, prevents plastic casing indent or generation deformation under external force.Adopting under traditional plastic casing condition, inner only installation one joint CR17335 battery, can meet the 3V supply power voltage of electric equipment.
