Abstract
The utility model relates to a vehicle anti-electromagnetic interference shielding connecting device, wherein the cable plugging end of a terminal row is added with bus bars and shielding clips for grounding processing, skinless cables are connected with the bus bars through the shielding clips, the shielding layers of the cables are directly connected with the bus bars thereby thoroughly ensuring the reliable grounding connection of the cables. The vehicle anti-electromagnetic interference shielding connecting device comprises a terminal row mounted in a wire groove, at least one row of bus bars connected with a grounding end on the wire groove, and cables with one end plugged into the terminal row, wherein the cables are clamped together with the bus bars through the shielding clips. The bus bars connected with the grounding end provide wall mending measures for a portion of unshielded zone of the cables, i.e., provide complementally grounding connection through bus bars.
Description
Technical field
The utility model relates to a kind of anti-electromagnetic interference shielding jockey that electrical system when wiring use that on rail vehicle, carries out, and belongs to mechanical manufacturing field.
Background technology
The rail vehicle of present domestic use like motor train unit train, subway and urban light rail etc., adopts highly intelligentized electrical system and network control mode at large.
Based on the complexity of control system wire structures, higher requirement is arranged for the anti-electromagnetic interference performance of cable that transmits travel condition of vehicle data and control signal.Though existing cable is enclosed with screen, at the end sections of cable connector, still exist not shielding area of part in terminal board, be easy to formation and shield the blind area and exist safe handling hidden danger.
In view of this special present patent application that proposes.
The utility model content
The described vehicle anti-electromagnetic interference shielding of the utility model jockey; Its purpose of design is to address the above problem and has additional busbar and the shield clip that ground connection is handled at the cable connector end of terminal board; The cable of removing crust is connected with busbar through shield clip; The screen of cable directly is connected with busbar, thereby guarantees that up hill and dale cable carries out the connection of reliable ground connection.
For realizing above-mentioned purpose of design, described vehicle anti-electromagnetic interference shielding jockey mainly includes the terminal board that is installed on the wire casing, and the difference with the prior art part is:
Wire casing is provided with the busbar that at least one row is connected with earth terminal,
One end is plugged in the cable of terminal board, is held on busbar through shield clip.
Like above-mentioned basic scheme, the busbar that is connected with earth terminal to the part of cable not shielding area the measure of safe benefit wall is provided, promptly replenishing through busbar provides ground connection connection.
For stably cable clip being held in busbar, can be provided with the Spring Card that is used to tighten cable by shield clip.Spring Card both can guarantee good being electrically connected, and also can compensate to the screen mechanical deformation of cable.
For further improving the flexibility that cable connects, can on wire casing, be provided with two groups of busbars and shield clip symmetrically.
As above content, the advantage that the utility model vehicle anti-electromagnetic interference shielding jockey has is:
1, replenishes and strengthen the ground connection processing of cable connector end through shield clip, busbar, thereby improve the anti-electromagnetic interference performance of cable up hill and dale, guarantee safe, the reliable use of cable.
2, connection and clamping device are simple for structure, can guarantee that cable is clamped in busbar reliably
Description of drawings
The following accompanying drawing of existing combination is done explanation further to the utility model
Fig. 1 is the structural representation of said anti-electromagnetic interference shielding jockey;
Fig. 2 is the generalized section of Fig. 1;
As depicted in figs. 1 and 2, wire casing 1, terminal board 2, busbar 3, cable 4, shield clip 5, Spring Card 6.
Embodiment
Be installed on the terminal board 2 on the wire casing 1;
Upper and lower end at wire casing 1 is provided with 2 groups of busbars 3 respectively laterally, symmetrically, and busbar 3 is connected with earth terminal;
One end is plugged in the cable 4 of terminal board 2, is held on busbar 3 through shield clip 5;
On shield clip 5, also be provided with the Spring Card 6 that is used to tighten cable 4.
