Description
Technical field
The present invention relates to cable electromangnetic spectrum field, particularly relate to a kind of quick press mounting formula cable electromagnetic armouring structure.
Background technology
Reaching its maturity of electric automobile industry is more and more higher for the integration level necessitates of its electric drive system, meanwhile as the electric machine controller of one of electric automobile three-major-items just towards the future development of high power density and high speed transmission of signals, electromagnetic compatibility (EMC) problem of thing followed control system becomes increasingly conspicuous especially.Can electromagnetic wave be received as interconnective cable itself between module each in electric-control system, again can radiated electromagnetic wave, therefore cable is the better channels of conducted interference, is again the important source of radiated interference.The electromagnetic compatibility problem how solving cable becomes the key that whole electric-control system is tested by EMC.At present, the traditional approach solving electric-control system cable EMC problem generally has the following two kinds:
1, adopt increase in the connectors shell fragment, compressing tablet, spring or other elastic constructions contact with the metal screen layer of cable after grounding, this method requires higher for the shielding properties of connector, corresponding connector cost compare is high, in addition, bad to the maintainability of cable, general cable is through after connector, and elastic construction penetrates direction by its metal screen layer along wire and blocks, once extract cable, its elastic construction can destroy the metal screen layer on cable;
2, be connected as shielded conductor feature with a separate conductors after the metal screen layer of cable peels off colligation, then by these independently shielded conductor and shell common ground, although this method can avoid the destruction of metal screen layer, the colligation of metal screen layer and the making of shielded conductor are wasted time and energy.
For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technical scheme described below produces under this background.
Summary of the invention
Technical problem to be solved by this invention: the deficiency existed for existing cable electromagnetic armouring structure and provide a kind of and avoid destroying cable metal screen layer when demolition and maintenance, reduce the stripping of cable metal screen layer and require, install simple and fast, Stability Analysis of Structures reliable quick press mounting formula cable electromagnetic armouring structure.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of quick press mounting formula cable electromagnetic armouring structure, comprise lower platen and top board, described lower platen is arranged on the shell mount pad of electric machine controller, described lower platen being arranged at intervals with along its length some is the junction block of one-to-one relationship with the entrance hole of the shell of electric machine controller, each junction block offers one for being embedded the wiring groove of cable metal screen layer, described top board is removably pressed together on lower platen and the cable metal screen layer that will be undertaken in each wiring groove of described lower platen compresses.
In a preferred embodiment of the invention, the elongated platy structure of described top board, the position that described top board corresponds to each junction block is formed with a junction block fitting portion upwards caved in, the bottom of each junction block fitting portion raises up formation one arc groove, when described top board is pressed together on described lower platen, the junction block fitting portion of described top board is fastened on the junction block of described lower platen accordingly, the close contact and the part that arc groove on described junction block fitting portion and cable metal screen layer expose described wiring groove cooperatively interacts.
In a preferred embodiment of the invention, described top board and the connected mode between lower platen be that bolt is connected, buckle connects or interference fit connect in one.
In a preferred embodiment of the invention, with boltsly between described top board and lower platen be: described lower platen offers at least one threaded bolt mounting holes respectively between its two ends and adjacent two junction blocks that the position corresponding to each bolt mounting holes of described lower platen at described top board offers a bolt hole respectively; During installation, described top board is pressed together on described lower platen, then adopts bolt to be screwed in the bolt mounting holes of described lower platen through after the bolt hole of described top board respectively.
Owing to have employed technical scheme as above, beneficial effect of the present invention is: one or more cable quick press mounting can be fixed on the shell of electric machine controller by electromagnetic armouring structure of the present invention, ensure electromagnetic compatibility, significantly can reduce the cost of connector, avoid the destruction of metal screen layer during cable demolition and maintenance.In addition owing to adopting upper and lower pressure plate structure, the stripping of the metal screen layer of cable requires greatly to reduce, and saves the Production Time of cable shielding cable feature.According to the actual conditions of the shell of electric machine controller, upper and lower pressing plate can be with bolts, and the various ways such as buckle connection and interference fit are fixed, and fixed form is versatile and flexible, and the compatibility for different electronic control module cable is good.
