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.

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, 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 anodal hole and negative pole hole, the positive terminal of described plain battery is near anodal hole, the lower end of described columnar stays frame is near the negative pole hole, the negative pole end of described plain battery is connected with the upper end spot welding of described columnar stays frame by nickel strap.
Be provided with the insulation interlayer between described the first battery cavities and described the second battery cavities, can prevent the short circuit of plain battery.
A side of described columnar stays frame is the cambered surface sidewall, and the columnar stays frame is flat sidewall towards the one side of insulation interlayer, and the inwall of described cambered surface sidewall and the second battery cavities is close to, and described flat sidewall and described insulation interlayer 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 interconnects for the side by three support plates the triangular prism that forms, the structure of upper backup pad and lower supporting plate is identical, described upper backup pad comprises most of arc limit and a straight flange, the inwall of described arc limit and the second battery cavities is close to, and described straight flange and described insulation interlayer are close to.Prevent plastic casing indent or distortion under external force.
Described plastic casing comprises tubular plastic housing and vinyl cover, passes through the ultrasonic drilling machine welding between described tubular plastic housing and described vinyl cover.The assembling of lithium battery is convenient.
Plain battery and the component weight in the second battery cavities in described 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 the columnar stays frame substitutes traditional cell, prevents plastic casing indent or generation deformation under external force.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.
