Embodiment five：
The present invention also provides a kind of battery modules (not shown).The battery modules include battery (in figure
It is not shown) and described lead frame assembly 102.The connector 20 of the lead frame assembly 102 and institute
State battery electrical connection setting.Technology of the specification, parameter of the battery all known by those skilled in the art
And be not emphasis of the present invention, it will not be repeated here.In the present embodiment, the battery is electronic for driving
The battery of automobile.In order to save space so that compact overall structure, the battery is arranged on described for battery
The lower section of the chassis body 11 of the lead frame 101 of module and with the setting unit 12 just to set.
It should be noted that the present invention can mentioned in " on " with " under ", " upper end " and " lower end ", " on
Side " is relative concept with " lower section ".Specifically, the chassis body 11 is arranged on described set in the present invention
Put " lower end " that " upper end " in portion 12, the base 13 are arranged on the setting unit 12.
Compared with prior art, the present invention for the chassis body 11 of the lead frame 101 of battery modules along setting
Put the edge of portion 12 to be extended, so that chassis body 11 can only set connector 20, and by circuit
Plate 30 is arranged in the setting unit 12.Due to needing to set corresponding electronic component 66 on circuit board 30,
So as to be provided with larger thickness or height, and in requisition for the larger space of occupancy.Circuit board 30 is set
In the setting unit 12 so that chassis body 11 has larger space can on thickness or short transverse
Battery is installed.Thus, the lead frame 101 improves space availability ratio, and is made by rational deployment
Obtaining battery has bigger installing space, so that battery modules can have the ability for exporting bigger electric power.
Preferably, the installation portion for installation connecting element 20 of the lead frame 101 for battery modules
111, which are set to holding part, is not only convenient for dismounting, and further reduces on the thickness direction of chassis body occupancy
Space.The bottom of the holding part offers the connection that through hole 113 is not only convenient for connector 20 and battery, and
And be conducive to quick heat radiating.In addition, the chassis body 11 also includes terminal guide portion 116, can not only
It is easy to arrange the connection terminal of connector, and will not occurs with other components, wire etc. because contacing by mistake
Caused short circuit, without the short-circuit protection of additional designs such as fuse etc.The connector 20
All connection terminals 28 along the side of the setting unit 12 close to (or perpendicular to) described lead frame 101
To being extended to be connected on same circuit board 30, so that in the direction along the close setting unit 12
When above there is at least two connectors 20, it is not necessary to more than one piece of circuit board 30 is set and not need other
Lead frame assembly part 102 is converged the electric signal of various boards 30 or other processing.Along close
Or on the direction of the setting unit 12 perpendicular to the lead frame 101, the setting unit 12 is shifted to install,
So that battery accordingly can shift to install to make full use of space.Along adjacent or perpendicular to described
On the direction of the setting unit 12 of lead frame, between the different terminal guide portions 116 of the chassis body 11
Setting can be connected, so as to not only save space, and the signal of different batteries that will be collected is adapted to
Or the requirement that electric current, the voltage of output are converged.
Preferred embodiments of the present invention are these are only, are not used to limit to protection scope of the present invention, Ren He
Modification, equivalent substitution or improvement in spirit of the invention etc., all cover in scope of the presently claimed invention.
