On the premise that the shape and the size of the battery product are unchanged, the 9V lithium battery structure adopts the low-temperature injection-molded battery case and the whole inner space of the battery is filled with low-temperature injection-molded plastic, thereby ensuring that the connection of individual parts is more compact and the structure is more reliable and greatly improving the performance and service life of the battery.
Description
Technical field
The utility model relates to a kind of lithium battery, specifically a kind of improvement of 9V lithium battery structure.
Background technology
The 9V lithium battery is a kind of common battery kind, is widely used in many fields such as medical treatment, wireless security, security protection, music, sound equipment.
The lithium battery of general 3 3.0V of 9V quadrate lithium battery is in series, and existing 9V lithium battery housing mainly adopts metal-back or plastic casing to encapsulate.As the disclosed 9V rechargeable battery of China's No. 01234377.3 patent " 9V rechargeable battery " is to adopt metal-back, and U.S. Patent number to be the patent documentation of US134046 disclosed is to adopt the injection molded method to come the square 9V battery case of injection moulding, battery case inside is divided into three cells, per three electric cores are put into wherein, after the thermoplastic sealing three electric cores of list are connected into the 9V lithium battery.
Existing this class encapsulating structure; all be three box hat battery series connection; and with gummed paper or glue it is made up after connecting the protective circuit plate; then electric core directly is placed in the battery container of moulding in advance; this structure may cause between each parts of electric core existing big gap, cooperate not compact, defective such as bonding strength is not enough; when battery is subjected in various external force reason, be easy to generate the pad sealing-off, influence battery performance.
The utility model content
Technical problem to be solved in the utility model provides the 9V lithium battery structure of a kind of compact conformation, dependable performance.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
Design a kind of 9V lithium battery structure, comprise housing and the positive terminal, the negative terminal that are connected on the housing, include three transversely arranged 3V box hat electricity core, electric core front ends in the housing and be connected with circuit board, battery container is made by the low temperature injection moulding, and the battery container internal voids is filled with mould-injection.
Described positive terminal, the negative terminal sheet riveted and fixed that the fixed position is used during by a low temperature injection casing.The positive and negative electrode terminal of electricity core is connected by the spot welding of L type nickel strap with circuit board
For improving the fail safe of battery, technique scheme is further improved, one in parallel prevents that single electric core from overcharging the diode with reversal connection on each box hat electricity core, simultaneously at the thermistor of a short-circuit protection of circuit board series connection.
For the ease of fixing, have the block location hole on housing top.
The utility model is compared has following remarkable result:
The utility model adopts low temperature injection moulding mode to form the 9V battery container, guarantee in the time of injection moulding that the low temperature mould-injection is full of between the interior box hat electricity of the battery container core, thereby it is compacter to make that the interior each several part part of battery connects, and structure is more reliable, has promoted the performance and the useful life of battery greatly.
Description of drawings
Accompanying drawing 3 is the positive view of the utility model.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Shown in accompanying drawing 1～3, a kind of 9V lithium battery structure comprises housing 1 and the positive terminal 7, the negative terminal 8 that are connected on the housing 1.Battery container 1 is made by the low temperature injection moulding, and battery container 1 internal voids is filled with mould-injection.This battery structure both can be so that the connection of each several part part be compacter in the battery, and structure is more reliable, and can promote the performance and the useful life of battery greatly.
Include three transversely arranged 3V box hat electricity core 2, electric core 2 front ends in the battery container 1 and be connected with circuit board 3, electric core 2 front end positive and negative electrode terminals link together by L type nickel strap and circuit board 3 spot welding.In order to prevent over-charging of battery or reversal connection, diode 5 in parallel on the electric core of each in battery.Because battery can generate heat in use the short time short circuit may take place; so thermistor 6 of on circuit board 3, connecting; thermistor 6 can pass through temperature controlling resistance value size in the short circuit process, plays a protective role, and makes battery not have blast, dangerous generation such as on fire.
The inside battery parts connect finish after, whole link inserted in the mould forms battery container 1 by low temperature injection moulding mode.When the low temperature injection-moulded housing, be equipped with sheet 4 and fix the inside battery position component.Positive terminal 7, negative terminal 8 as battery current output then are fastened on the sheet 4 with rivet.
Temperature drift, is preferably in and is equipped with cooling system in the injection molding machine during low temperature injection moulding battery container 1 influence of battery in the injection moulding process in order to reduce.
