Abstract

The utility model relates to an accumulator battery which assembles a plurality of secondary batteries into a whole. The utility model is composed of a bottom case and an upper cover, and the upper cover is provided with an input socket, an output socket and a safety device. The utility model is characterized in that the bottom case is a grating texture which is made of insulating materials, and each grid is provided with a monomer battery without a casing and a top cover; the positive and the negative electrodes of each two batteries are connected, and all monomer batteries after connected in series is connected with an input socket and an output socket of the upper cover. The utility model has the advantages of light weight, small size, low cost price, etc.

Description

Batteries

The utility model relates to a kind of batteries that a plurality of secondary cells is assembled into one.

Secondary cell because of its can the repeated multiple times charge and discharge characteristic, be often used as the power supply of electronics, electrical equipment, daily product etc., the general connected mode that adopts series connection combines cell.Common has: NI-G, ni-mh, smee cell etc. are composed in series various power supplys; for example commercially available " Sunyu " board smee cell group and " upright bright " board nickel-cadmium cell group etc.; its general configuration is: the existing storage battery group is made up of end box and loam cake; in box body, closely be arranged with a plurality of cells successively; it is together in series to satisfy the required voltage request of product, and its loam cake is provided with input socket, accessory power outlet and the safety guard etc. that link to each other with battery pack.But this batteries exists Heavy Weight, cost height, bulky deficiency.

The purpose of this utility model is a kind of new structure, the specific energy (gravimetric specific energy and volumetric specific energy) of raising power supply and reduction power supply cost of dressing up power supply with the battery strings joint group of design.

The technical scheme that realizes above-mentioned purpose is: this batteries is made up of end box and loam cake; loam cake is provided with input socket, accessory power outlet and safety guard; it is characterized in that end box is the grating texture of being made by insulating material; be placed with one in each grid not with the cell of shell and top cover; the both positive and negative polarity of per two batteries links to each other, and all do not link to each other with input socket, the accessory power outlet of loam cake with the cell series connection back of shell and top cover.

This batteries compared with prior art, its crucial part is that each cell all is not with shell and top cover, in the grid of the end box of directly packing into when making batteries.Therefore because the utility model saved the shell and the top cover of cell, thereby have in light weight, volume is little and low cost and other advantages.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the cutaway view of Fig. 1.

Fig. 4 is the structural representation of another embodiment of the utility model.

As shown in Figure 1 and Figure 2, the structure and the prior art of profile of the present utility model and loam cake 1 are basic identical, and loam cake is provided with safety air vavle 3, accessory power outlet 4, input socket 5.Difference is the structure of end box 2 and the modes of emplacement of cell.As Fig. 2, shown in Figure 3, end box is made the rectangle grating texture, the cell 7 with shell and top cover directly is not placed in the grid, battery of every lattice, the number of grid is decided on actual needs, the shape of grid also can be made the circular grid (as shown in Figure 4) that is suitable for cylindrical battery, and the both positive and negative polarity of per two batteries 7 is communicated with by lug 6, is connected with accessory power outlet 4, input socket 5 after all batteries are in series.

Owing to the structure of loam cake, loam cake all belongs to prior art with being connected of battery pack, does not repeat them here in the utility model.Convenient for processing and fabricating, end box should adopt plastics, particularly pressure-resistant plastic manufacturing.This batteries is applicable to the power supply that all secondary cells such as series connection such as NI-G, ni-mh, silver-colored zinc and lithium ion battery are assembled into, and can be widely used in the news lamp power supply, shoot with video-corder picture power supply, aircraft emergency power supply, electric vehicle power sources etc.

Claims

1, a kind of batteries; form by end box and loam cake; loam cake is provided with input socket, accessory power outlet and safety guard; it is characterized in that end box is the grating texture of being made by insulating material; be placed with one in each grid not with the cell of shell and top cover; the both positive and negative polarity of per two batteries links to each other, and all cell series connection backs link to each other with input socket, the accessory power outlet of loam cake.

2, batteries according to claim 1 is characterized in that each lattice of end box grating texture are rectangular or circular.

3,, it is characterized in that end box is to be made of plastics according to claim 1,2 described batteries.

4, batteries according to claim 1 is characterized in that not being with the cell of shell and top cover is NI-G, ni-mh, silver-colored zinc, lithium ion battery secondary cell.
