Abstract
The utility model discloses a 3V lithium battery which is characterized by comprising a plastic casing and a battery cell, wherein the plastic casing is internally provided with two cell cavities, namely a first battery cavity and a second battery cavity respectively; the battery cell is mounted in the first battery cavity; a conductive triangular-prism support bracket is mounted in the second battery cavity; a positive pole hole and a negative pole hole are formed in one end of the plastic casing; a positive pole end of the battery cell is close to the positive pole hole; and the lower end of the triangular-prism support bracket is close to the negative pole hole; and the negative pole end of the battery cell is in spot-welding connection with the upper end point of the triangular-prism support bracket through a nickel strap. The 3V lithium battery has the advantages that the traditional single cell is replaced with the triangular-prism support bracket, so that the phenomenon that the plastic casing sags or is deformed under the action of an external force is prevented. In the case of adopting the traditional plastic casing, only is one CR17335 cell mounted inside, and 3V power supply voltage of electrical equipment can be met.
Description
Technical field
The utility model relates to a kind of lithium battery, especially relates to a kind of 3V lithium battery.
Background technology
Lithium battery is mainly used in the electrical appliance fields that capacity required is big, 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 not fitted into new electric equipment.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of overall dimension is identical with the CR-P2 lithium battery, voltage is the lithium battery of 3V.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of 3V lithium battery, comprise plastic casing and the plain battery of a joint, have two battery cavities in the described plastic casing, be respectively first battery cavities and second battery cavities, described plain battery is installed in first battery cavities, conductive triangular column bracing frame is installed in 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 triangular column bracing frame is near the negative pole hole, and the negative pole end of described plain battery is connected by the upper end spot welding of nickel strap with described triangular column bracing frame.
Be provided with the insulation interlayer between described first battery cavities and described second battery cavities, can prevent the short circuit of plain battery.
Described triangular column bracing frame comprises upper backup pad, lower supporting plate and pillar, described upper backup pad links to each other 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 the triangular prism of forming for the side by three support plates, 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 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 the described vinyl cover.The assembling of lithium battery is convenient.
Plain battery and the component weight in second battery cavities in described first battery cavities equate, make the weight ratio of lithium battery interior balanced, in the electric equipment use, have more stable power supply performance.
Compared with prior art, the utility model has the advantages that triangular column bracing frame substitutes traditional cell, prevent 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.
