Description

A kind of secondary lithium battery end component

Technical field

The utility model relates to a kind of battery component, in particular to a kind of secondary lithium battery end component.

Background technique

With the development of secondary cell technology, the performance of secondary cell has a quick promotion, while its cost is also substantially Degree decline, especially the secondary cell high-energy density having, the characteristics of can be recycled, thus obtained more and more extensive Using.Such as the rechargeable lithium ion batteries in secondary cell, have become mobile phone, laptop, camera mainly for Battery, and in traditional application field such as remote controler, flashlight, toy etc. of many one-shot batteries, secondary cell also by Step is substituted by one-shot battery.

But secondary cell still has inconvenience compared with one-shot battery in use.One-shot battery does not need to fill Electricity, and secondary cell needs to be charged with dedicated charger, while in order to keep normal performance, often secondary cell needs Charging process and electric discharge use process are managed and are protected.Under normal conditions, secondary cell substitution one-shot battery carries out It uses, it is necessary first to secondary cell be packed, charging and discharging protection device, voltage management dress are set in secondary cell shell It sets, to form the product for being able to satisfy one-shot battery equipment requirement, there are technology of the package complexity, cost for this way The problems such as high, battery packages product final shape is difficult to control, while there is also secondary lithium battery after packaging outer The problem of shape size is unsatisfactory for requirements of the national standard；In addition, to meet the needs of secondary lithium battery charging, configuration is independent Charger for lithium ion battery, will thus increase its application cost, while the storage of charger needs space, this will be serious Secondary cell is constrained to use in the popularization of numerous application fields of one-shot battery and substitution.

Therefore, how by the requirement of the performance characteristics combination one-shot battery of secondary cell, by secondary cell battery pipe Reason, one-shot battery contour structures, one-shot battery use demand plan as a whole optimization, take into account cost and efficiency, propose a new battery Structure member solution, is just very necessary.

Utility model content

The utility model is intended to provide the secondary lithium battery end component that a kind of structure is simple, easy for installation.

The utility model is realized by following scheme:

A kind of secondary lithium battery end component, including bung, cap head and deck, the bottom of the cap head are provided with bullet Piece, edge of the cap head bottom in addition to elastic slice position are provided with skirt, and the deck is integrally in cylindrical structure, institute State and offer the perforation of cap head elastic slice at the top of deck, the bottom of the deck offers USB perforation, cap head elastic slice perforation with USB perforation, which is interconnected, forms USB placement space, and the side vertical hanging that the top of the deck is located at the perforation of cap head elastic slice is set It is equipped with the elastic slice accommodating groove of through slot structure, it is spaced apart between the elastic slice accommodating groove and USB placement space inner wall, it is described The top of elastic slice accommodating groove is provided with baffle on bottom position, opens up fluted, institute respectively on the outside of the two sides of the deck It states and is vertically installed with raised fixture block on bottom portion of groove, the protrusion fixture block is vertically installed on the end position on the lower of one side outwardly First raised rib block, the bung generally inner hollow, bottom opening cylindrical structure, offer at the top of the bung Cap head is perforated, and is respectively perpendicular on the inner wall of the bung two sides and is provided with raised through slot, and the protrusion of the protrusion through slot and deck is blocked Block complements one another, and the protrusion through slot bottom is vertically installed with the second raised rib block, the described second raised rib on end position on the lower The raised rib block mutual dislocation of the first of the raised fixture block of block and deck is fastened togather, and the described second raised rib block plays limit, branch Support and locking action, the mating set of cap head is on deck and the elastic slice of cap head is placed in the elastic slice accommodating groove of deck, elastic slice Baffle on accommodating groove blocks elastic slice lower end, and the deck is mating to be fastened in bung and cap head passes through the cap head of bung and wears Simultaneously part is exposed in hole.When actual fabrication, the spacing distance between the elastic slice accommodating groove on deck and USB placement space inner wall can root According to needing to be adjusted, covers easy to operate when on elastic slice accommodating groove and be not easy to drop out i.e. to meet the USB in corresponding battery It can.Raised fixture block can be selected as needed in the setting position of bottom portion of groove, and generally raised fixture block is arranged in groove-bottom On the middle position in portion, it is stronger to may make that deck is fixed to each other with bung.

Further, end position is bent to form boss, the high card release of projection section to the elastic slice of the cap head outwardly on the lower The elastic slice accommodating groove end face of seat.The boss of the elastic slice is arc-shaped, to guarantee that elastic slice contacts well with USB.

Further, the two sides at the top of the bung offer through-hole, the top phase of the through-hole and raised through slot respectively It is logical.The setting of bung through-hole can facilitate deck to dismantle away the through-hole that two sides open up at the top of bung, most important work out of bung With being simplified mould structure, mold is facilitated to process, mold is designed using upper and lower mould conjoint structure, oblique top that thus it goes without doing demoulding , and because this product diameter is very small, the stroke of oblique top is inadequate, and it is best using conjoint structure design effect, it secondly can Increase the aesthetics of product.

Further, the bottom of the deck is provided with several magnet mounting grooves, peace in each magnet mounting groove Equipped with strong magnets.

Further, the two sides of the elastic slice accommodating groove of the deck are respectively arranged with rectangular support column, the support It is fixed at the top of column on the top of deck, i.e., support column is linked together with deck.Reinforcement of the support column as elastic slice accommodating groove Muscle cooperates the design of elastic slice accommodating groove, can be very good wanting for the USB close contact for meeting cap head elastic slice and corresponding battery It asks, while there is good intensity, can avoid that serious deformation occurs, guarantee that cap head part is straight, to guarantee cap head and outer Equipment contact in portion's is good.

Under normal circumstances, bung, deck are made of plastic material, and cap head is made of hardware material.

A kind of secondary lithium battery end component of the utility model, has the advantage that

1, structure is simple, easy for installation, it is only necessary to be fastened in cap head is mating on deck and cap head elastic slice is mounted on card In the elastic slice accommodating groove of seat, then it is fastened in bung is mating on deck；
