Description
Technical field
The utility model relates to charging pile field, in particular to a kind of PDU copper busbar fixed structure.
Background technique
Currently, charging pile power distributing unit PDU is using more and more, but the electric current of PDU is bigger, leads to copper busbar
It is bigger, and connection bolt reaches M10-M12, and the copper bar on PCB is connected on PCB by soldering, due to weld strength and PCB
The characteristic of material, prevent copper bar is from bearing biggish stress, and copper bar when wiring since bolt is larger, bolt fastening
When very big torsion be easy to so that copper bar deformation causes copper bar to fall off pad or damage pcb board, while big cable meeting
Cause biggish stress, if being not fixed copper bar, long-term affected by force is influenced life of product by pcb board.Portioned product in order to
The stress for reducing copper bar, can only be using high-cost flexible copper bar when wiring, and difficulty of processing at high cost is big.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of PDU copper busbar fixed structures, have high intensity,
The frame mode of high-bearing capacity allows copper bar to bear biggish stress in wiring, at low cost, and assembly is simple, reliability
It is good, it can effectively solve the problem that deficiency in the prior art.
The utility model is achieved through the following technical solutions: a kind of PDU copper busbar fixed structure, including casing
Lower cover, casing upper cover, copper bar fixation kit and pcb board, increase by first fixing piece on the pcb board, and pcb board was by should
First fixing piece, which is screwed, to be installed under casing on lid, the copper bar fixation kit include the first copper bar, the second copper bar,
The opposite face of second fixing piece and third fixing piece, second fixing piece and third fixing piece opens up a copper bar card
Slot, the first, second copper bar two sides are respectively charged into copper bar card slot and are locked by second, third fixing piece of two sides, described
Become the casing structure of an entirety between casing lower cover and casing upper cover by the locking of long foot bolt.
Casing lower cover bottom is provided with a bending edges as a preferred technical solution, and bending edges are formed with casing upper cover
One closed casing.
The position for facing long foot bolt on second, third described fixing piece as a preferred technical solution, opens up one
A corresponding screw hole location, the long foot bolt pass through the screw hole location on second, third fixing piece and fix entire copper bar
Component locking is installed between casing.
First fixing piece, the second fixing piece and third fixing piece are all made of insulation as a preferred technical solution,
Material is made.
The beneficial effects of the utility model are: the utility model has high intensity, the frame mode of high-bearing capacity, so that copper
Biggish stress can be born when coming wiring, at low cost, assembly is simple, good reliability.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Description of symbols:
1, casing lower cover；2, the first copper bar；3, the second fixing piece；4, the second copper bar；5, third fixing piece；6, first is fixed
Part；7, casing upper cover；8, pcb board；9, screw；10, long foot bolt.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, including casing lower cover 1, casing upper cover 7, copper bar fixation kit and pcb board 8, increase on pcb board 8
One the first fixing piece 6, pcb board 8 are fixedly installed on casing lower cover 1 by first fixing piece 6 by screw 9；
Copper bar fixation kit includes the first copper bar 1, the second copper bar 4, the second fixing piece 3 and third fixing piece 5, and second is solid
The opposite face for determining part 3 and third fixing piece 5 opens up a copper bar card slot, and the first, second copper bar two sides are respectively charged into copper bar
It is locked in card slot and by second, third fixing piece of two sides, passes through long foot bolt between casing lower cover 1 and casing upper cover 7
10 lockings become the casing structure of an entirety.
In the present embodiment, 1 bottom of casing lower cover is provided with a bending edges, and bending edges and casing upper cover form a closing
Casing.Since casing lower cover increases a bending edges and casing upper cover one closed casing of formation, enhance entire
The rigidity of system.
The position that long foot bolt is faced on second, third fixing piece 3,5 opens up a corresponding screw hole location, described
Long foot bolt pass through second, third fixing piece on screw hole location and by entire copper bar fixation kit locking be installed on casing it
Between.Due to being all limited up and down for copper bar, so that copper bar does not have displacement, copper bar and casing become an entirety, by
Power situation is greatly improved.
In the present embodiment, the first fixing piece, the second fixing piece and third fixing piece are all made of insulating materials and are made.
The beneficial effects of the utility model are: the utility model has high intensity, the frame mode of high-bearing capacity, so that copper
Biggish stress can be born when coming wiring, at low cost, assembly is simple, good reliability.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
