Embodiment
Below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof, the detailed description of further indefiniteness is done to technical solutions of the utility model.
As shown in Figure 1, wire harness installation component 100 first execution mode that the utility model has an isolation comprises bolt 1, nut 2 supporting with it and a pair clip 3.The threaded shank 11 of described bolt 1 is arranged with the separator 4 of tubulose.In connection status, this separator 4 is limited between this pair clip 3, and the tube chamber of separator 4 and threaded shank 11 matched in clearance.
Clip 3 is made up of ring part 31 and line part 32, is provided with through hole 33 at line part 32, is enclosed with cushion 34 at ring part 31.During making, cushion 34 is made the endoporus shape corresponding with the cross section of ring part 31 and is enclosed within ring part 31.Cushion more than 34 adopts refractory material to make, and have certain elasticity, and material itself has larger coefficient of friction.Line part 32 comprises top 321 and bottom 322, and is increased gradually to away from side by ring part 31 side between top 321 and bottom 322.The project organization of this bottom 322 is first to downward-extension one segment distance, then extends along opposite upper parts 321 parallel direction, by this, is formed with certain angle " R ", can improves the elastic performance of clip 31 between bottom 322 and top 321, provide good pretightning force effect.This angle " R " is generally optional between 0 ° ~ 20 °.Through hole 33 runs through the surface of top 321 and bottom 322.In connection status, when nut 2 screws, clip 3 can provide stronger clamping action to wire harness.
Fig. 2 is the assembly drawing that the utility model has wire harness installation component 100 first execution mode of isolation, which show state in use, and the clip 3 that clip 3 clamps, wire harness B is in bottom that wherein wire harness A is in top clamps.Separator 4 between clip 3 to provide isolation to upper and lower clip 3.When tightening nut 2, the clip 3 on top is isolated part 4 and grips with the head 12 of bolt 1, and the clip 3 of bottom is isolated part 4 and nut 2 clamps.Be fastenedly connected on support 200.Certain isolation distance can be remained between wire harness A, B.
In addition, in a kind of update scheme preferably, for guaranteeing the stability be connected between clip 3 with bolt 1 further, between the head 12 and clip 3 of bolt 1, and the end of screw rod 11, be provided with elastic washer 5 between nut 4 and clip 3, paired setting taked by elastic washer 5, maintains the stability of connection of between the clip 3 of connection and isolation 4 further.
The described separator 4 of this execution mode execution mode can adopt metal material processing shaping, or adopts engineering plastics machine-shaping.
There is as Fig. 3 the utility model the three-dimensional exploded view of second execution mode of the wire harness installation component 100' of isolation; Comprise, bolt 1', nut 2', the first clip 3A', the second clip 3B', and the separator 4' being located at the tubulose between described first clip 3A', the second clip 3B'.Preferably, the top of separator 4' is provided with the screw 40' matched with the structure of described bolt 1', be provided with the screw rod 41' identical with the structure of described bolt 1' in the bottom of separator 4', the centre position of the first clip 3A', the second clip 3B' offers through hole (not shown).Then connection status as shown in Figure 3, the screw rod 41' being in the separator 4' on top matches with the screw 40' of the separator 4' of bottom by through hole and is connected to each other, first clip 3A', the second clip 3B' are placed between separator 4' in this way, bolt 1' is connected to the screw 40' of the separator 4' be in topmost, and nut 2' connects the screw rod 41' of separator 4' bottom and the wire harness installation component 100' this with isolation is fastenedly connected on support 200.For guaranteeing the stability connected between clamp bolt 1', nut 2' further, between bolt 1' head and the first clip 3A', and be equipped with elastic washer 5' between the end of screw rod 41' and the second clip 3B', the stability that the connection keeping the first clip 3A', the second clip 3B' and separator 4' is further set of elastic washer 5'.
The wire harness installation component 100 that the utility model has isolation also can adopt the stacking form of clip 3, as shown in Figure 4, bolt 1 " three level stack clip 3 can be connected ", two-layer clip 3 adjacent " between separator 4 is set ", at same layer, also a pair clip 3 left and rightly can be set "; by this, can realize making full use of space, connect the object of more multi-thread bundle flexibly.
