Below technique scheme is further explained:
The curved sheet metal of described two-fold is two 90 degree bending sheet metals, and the last bending of sheet metal is last 90 degree bendings, and the following bending of sheet metal is 90 degree bendings down.
Described printed board ground wire hole link is the elasticity tuning fork structure, and the centre of described tuning fork structure is one " U " font fluting.
The end of described tuning fork structure is provided with to play the guiding role when ground strip inserts printed board ground wire hole and makes ground strip along the sliding protruding beak of guiding that inserts.
It is protruding that the protruding beak rearward end of described guiding is provided with card.
The described part that is connected and fixed is a rivet coating nut.
The end of described rivet coating nut has the anti-rotation cap in the groove of the connector metal shell of can packing into.
Described anti-rotation cap is square anti-rotation cap, and the groove of connector metal shell is a square groove.
Described rivet coating nut is provided with the chamfering of conveniently turning over riveting.
The utility model has the advantages that:
1, the device of reduction filter connector earth resistance of the present utility model, quick for installation, convenient disassembly, cost are low, and can effectively reduce earth resistance, improve the filtering performance of connector.
2, the device of reduction filter connector earth resistance of the present utility model reduces the overlap joint contact resistance, improves electric continuity.Solved in the prior art metal shell of connector contact with the printed board ground wire complicated, the problem that cost is high.
3, the device of reduction filter connector earth resistance of the present utility model is installed very conveniently, directly inserts in the hole that printed board reserves connector shell is contacted well with ground hole.When product keeps in repair, also can extract easily, have very high maintenanceability.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of ground strip of the present utility model;
Fig. 2 is the structural representation of rivet coating nut of the present utility model;
Schematic diagram when Fig. 3 is of the present utility model the use.
Wherein: 1 installing hole; 90 degree bendings on 2; 3 " U " font fluting; The protruding beak of 4 guiding; The bending of 5 times 90 degree; 6 cards are protruding; 7 locking holes; 8 square anti-rotation caps; 9 cylinders; 10 screw threads; 11 chamferings; 12 pallet stands; 13 printed boards; 14 printed board ground wire holes.
Embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of device that reduces the filter connector earth resistance, the rivet coating nut that it comprises ground strip and attaches it to the filter connector metal shell.
As shown in Figure 1, ground strip is the sheet metal of two 90 degree bendings.The last 90 degree bendings 2 of sheet metal are developed the housing mounted link for cooperating with the filter connector metal shell, and the shell link is provided with and is used to install the circular mounting hole 1 that is connected and fixed part.The cylinder 9 of rivet coating nut therefrom passes, and ground strip and connector shell are riveted together.
The following 90 degree bendings 5 of sheet metal are for inserting the printed board ground wire hole link in printed board ground wire hole 14, and printed board ground wire hole link is the elasticity tuning fork structure, and the centre of tuning fork structure is one " U " font fluting 3.The end of tuning fork structure is provided with the protruding beak 4 of guiding.The protruding beak 4 that leads plays guide effect when ground strip inserts printed board ground wire hole 14, ground strip is inserted along sliding.
