On fitting.Compared with being adhesively fixed in the prior art by conducting resinl, the present invention is connected and fixed by dual, realizes plate
Being stably connected with for grid and tab, improves the stability between grid and tab, further having reached prevents tab from grid
The effect to fall off, to extend the service life of battery；Furthermore conductive connector is used, in fixed grid and pole
While ear, conductive transmitting between the two will not influence, to improve the whole use feeling of battery.
Further, in the step A, connector is metal.Metal has good electric conductivity, connects grid and tab
In the process, it will not influence the electric conductivity between grid and tab, enable battery normal use.
Further, the metal is one of metal mesh, metal nail and metal coating or two or more combinations.
Further, the connector is electric conductor.
Further, the electric conductor includes metal layer and conductive non-metallic layer, and metal layer is coated on nonmetallic
The outside of layer.Electric conductor is formed by metal layer and non-metallic layer, in the case where guaranteeing electric conductivity, can be reduced golden in electric conductor
On the one hand the content of category can reduce the weight of electric conductor, on the other hand can reduce input cost；Metal layer is coated on non-
The outside of metal layer prevents tab from falling off from grid convenient for electric conductor to be connected on grid, and does not have to consider when installation
The direction of electric conductor saves the time of installation, improves the efficiency of installation.
Further, the non-metallic layer includes graphite linings and the semiconductor layer that is coated on the outside of graphite linings, and semiconductor layer is
Silicon layer.Compared with prior art, part metals are replaced by conductive graphite and semiconductor, conduction can either be reached
Effect, and can reduce the weight of electric conductor, to mitigate the weight of battery.Silicon has conduction as the most common semiconductor
Performance, and it is cheap.
Further, the groove for being connected and fixed is provided on the metal layer, groove is being distributed in each face of metal layer just
On center and quadrangle.Be arranged groove, can be welded by welding in groove, complete welding after, make electric conductor with
Grid forms face contact, enhances the effect being fixedly connected, prevents electric conductor from falling off.It is configured on center and quadrangle,
Workload can only be reduced when being welded and fixed, and can be achieved the effect that fixed.
Further, connection grid and when tab, first navigates to electric conductor on grid, then groove by electric conductor with
Grid is welded and fixed；Then tab is navigated on electric conductor, then the groove between tab and electric conductor is by tab
It is welded with electric conductor；When welding, it is located at pad in groove.
Further, be provided with limiting slot on the metal layer, connector is latch closure, one end of latch closure hingedly on the metal layer,
For the other end of latch closure for being inserted into limiting slot, one end that latch closure is inserted into limiting slot is needle-shaped.It is in needle-shaped for being arranged, for the ease of ring
Button is inserted into grid or tab, and electric conductor is fixedly connected on grid or tab is fixedly connected on electric conductor, is prevented
Tab falls off from grid.
Further, when connection grid is with tab, the latch closure of electric conductor and grid contact side is first rotated, latch closure is inserted into limit
One end of position slot bypasses or passes through grid, then turns back in limiting slot and is locked, electric conductor is fixedly connected on grid；
One end of latch closure insertion limiting slot is bypassed or passes through tab, then by the then latch closure of rotation electric conductor and tab contact side
It turns back in limiting slot and is locked, finally tab is fixedly connected on electric conductor.
Detailed description of the invention
Fig. 1 is the schematic diagram of the embodiment of the present invention two.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: metal layer 1, graphite linings 2, semiconductor layer 3, groove 4.
Embodiment one:
The connection method of grid and tab, comprising the following steps:
A, conductive connector is fixed on grid, connector is metal in the present embodiment, main to select gold
Belong to one of net, metal nail and metal coating or two or more combinations.Pass through weldering if selection metal mesh and metal nail
It connects and is fixed on grid；If selecting metal coating, by molten metal solution brushing on grid, after its solidification i.e.
It can.
B, tab is fixed by welding again on metal in step, so that it is solid to form tab and grid
Fixed connection.
Embodiment two is substantially as shown in Figure 1:
The difference between this embodiment and the first embodiment lies in: using electric conductor as connector, which includes metal layer 1
With conductive non-metallic layer, metal layer 1 is coated on the outside of non-metallic layer.Non-metallic layer includes graphite linings 2 and cladding
Semiconductor layer 3 in the outside of graphite linings 2, semiconductor layer 3 is silicon layer in the present embodiment.It is provided on metal layer 1 for being connected and fixed
Groove 4, groove 4 is distributed on the center and quadrangle in each face of metal layer 1；Limiting slot, metal layer 1 are provided on metal layer 1
It is equipped with connector (not shown), connector is latch closure in the present embodiment, and one end of latch closure is hinged on metal layer 1, ring
For the other end of button for being inserted into limiting slot, one end that latch closure is inserted into limiting slot is needle-shaped.
Electric conductor is formed by metal layer 1 and non-metallic layer, in the case where guaranteeing electric conductivity, can be reduced golden in electric conductor
On the one hand the content of category can reduce the weight of electric conductor, on the other hand can reduce input cost；Metal layer 1 is coated on
The outside of non-metallic layer prevents tab from falling off from grid convenient for electric conductor to be connected on grid, and does not have to examine when installation
The direction for considering electric conductor, saves the time of installation, improves the efficiency of installation.
When connection, first rotate electric conductor and grid contact side latch closure, by latch closure insertion limiting slot one end around (or
Person passes through) grid, it then turns back in limiting slot and is locked, finally electric conductor is fixedly connected on grid.Fixed mistake
Cheng Zhong is reinforced electric conductor and grid surface by spot welding to enable electric conductor more steadily to connect with grid；
It is welded when welding with groove 4 for solder joint, on the one hand using groove 4 as pad, after completing welding, makes electric conductor and grid
Face contact is formed, gap when reducing latch closure connection between electric conductor and grid further enhances the effect being fixedly connected, prevents
Electric conductor is fallen off, and 4 butt welding of another aspect groove picks up positioning action, can be prevented welding from deviating, be influenced the entirety of battery
Shape.Similarly, in fixed tab, the latch closure of electric conductor and tab contact side is first rotated, by latch closure insertion limiting slot
One end bypasses (or passing through) tab, then turns back in limiting slot and is locked, tab is finally fixedly connected on electric conductor
On, it is then reinforced by way of spot welding again, achievees the effect that dual fixation, prevent the caducous phenomenon of tab.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.
