Abstract
The utility model relates to an insulating layer-bent laminated bus marginal structure, which comprises at least one conductor layer (200) and insulating layers (100) corresponding to the conductor layer (200). The insulating layers (100) are arranged on the two sides of the conductor layer (200); and the extension ends (101) of the insulating layers (100) are bent and entangled into the space between the conductor layer (200) and the lower insulating layer. The laminated bus marginal structure provided in the utility model has insulating layers with bent edges, so as to save space and ensure more reliable insulation.
Description
Technical field
The utility model relates to a kind of stack bus bar, relates in particular to the marginal texture of this stack bus bar.
Background technology
At present a lot of electric products are brought into use the stack bus bar technology, to reduce stray inductance, obtain best electric property.Yet because the stack bus bar technology fits tightly both sides at insulating barrier with different conductor, distance between conductors is very near, so the insulation between the conductor becomes the key factor of stack bus bar design.
For the insulation of stack bus bar edge, dual mode is arranged in the prior art: first kind is to make the insulating barrier edge extend the conductor layer edge, development length be between conductor maximum creepage distance 1/2; Second kind is extended insulating barrier to be sticked with glue agent is bonding to make its sealing, and development length can be less than first kind of mode.Can not guarantee to seal completely yet stick with glue agent bonding, in case there is the space to exist, and creepage between conductor will take place when not enough in development length, causes failure of insulation, forms potential safety hazard.If will guarantee safe creepage distance, insulating barrier just must extend a quite long segment distance, is unfavorable for saving the space.
Summary of the invention
The utility model technical issues that need to address have provided a kind of stack bus bar edge structure of insulating barrier bending, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: at least the above conductor layer of one deck, with conductor layer corresponding insulation layer; Described insulating barrier is in two sides of conductor layer; Be involved between conductor layer and the following layer insulating after the elongated end bending of described insulating barrier.
Compared with prior art, the beneficial effects of the utility model are: saved the space by the mode that adopts the bending of insulating barrier edge, and can guarantee to insulate more reliably.
Description of drawings
Fig. 1 is first kind of structure at laminated bus edge in the prior art, and wherein 1 is insulating barrier, and 2 is conductor layer;
Fig. 2 is second kind of structure at laminated bus edge in the prior art, and wherein 10 is insulating barrier, and 20 is conductor layer;
Fig. 3 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 3: the utility model comprises: at least the above conductor layer 200 of one deck, with conductor layer 200 corresponding insulation layers 100; Described insulating barrier 100 is in two sides of conductor layer 200; Be involved between conductor layer 200 and the following layer insulating after elongated end 101 bendings of described insulating barrier 100.
Insulating barrier all needs to extend conductor one segment distance in the prior art, and is creepage to guarantee.Be bonded at the back side of conductor after the bending of the utility model with one 180 ° in the extended part work of insulating barrier, so just need not take the space of conductor outside, therefore the length of dogleg section just can lengthen as far as possible, even be bonded with the space, also can guarantee enough creepage distances.
