Embodiment
The wire harness sealing piece by an embodiment, the utility model being provided below with reference to Fig. 2 is described in detail, it is the utility model one optional embodiment, can think that those skilled in the art can modify and polish it in the scope that does not change the utility model spirit and content.
Please refer to Fig. 2, the present embodiment provides a kind of wire harness sealing piece, be installed on fire compartment wall, comprise seal body 100, described seal body 100 has at least comprised the rubber parts 101 passing for wire harness, this wire harness sealing piece also comprises the plastic base 104 that is fixed at described seal body 100 peripheries, described plastic base 104 is provided with elastic packing frame 105, described plastic base 104 contacts with described fire compartment wall by described elastic packing frame 105, in the time of bolt tightening, described elastic packing frame 105 is clipped between described fire compartment wall and plastic base 104.
Curve form and the described fire compartment wall surface of the side surface contacting with described fire compartment wall of described elastic packing frame 105 match.In the present embodiment, shape and the fire compartment wall surface of uper side surface as shown in Figure 2 match, and elastic packing frame 105 can be fitted completely with fire compartment wall, play best sealing effectiveness.
In the present embodiment, the material of described elastic packing frame 105 is polyurethanes (PU).The wire harness sealing piece of the present embodiment has adopted polyurethanes (PU) material for one week what fit with fire compartment wall, match with the curved surface of fire compartment wall laminating, utilize the elasticity of polyurethanes (PU) material, sealing after locking by construction bolt between realization and fire compartment wall, and in prior art, be that the region contacting with fire compartment wall at rubber parts adopts groove design, need when mounted groove to snap in set bolt again in fire prevention porthole, this design, the scheme of the present embodiment has been simplified the processing technology of rubber parts itself, also while having saved installation, groove snaps in the operating procedure of fire prevention porthole simultaneously, reduce man-hour, save cost.
In the present embodiment, on described plastic base 104, be also fixed with plastics bulge-structure 106, the shape of described plastics bulge-structure and position all with described fire compartment wall on panel beating breach match, the described elastic packing of correspondence position is set up on described plastics bulge-structure 106.Typically, the shape of the shape of described elastic packing frame 105 and described seal body 100 peripheries matches, but in the present embodiment due to the existence of plastics bulge-structure 106, elastic packing folder 105 only partial shape and described seal body 100 matches, but from the present embodiment, those skilled in the art can realize the structure that the shape of elastic packing frame 105 and the shape of described seal body 100 peripheries match completely.
In the present embodiment, described plastic base 104 is provided with three bolts hole 103.Described three bolts hole 103 are arranged around described seal body 100, thereby provide enough supports for whole wire harness sealing piece.The aperture of described bolt hole 103 matches with the size that is contained in advance the bolt on described fire compartment wall.And four bolts hole of available technology adopting, two are located on rubber parts, and two are located on fire compartment wall, that is the bolt arrangement of design is conventionally on both direction, make must overturn coaming plate before fire compartment wall of operator just can complete the installation of 4 bolts, increase working hour.Compare, the bolt hole 103 in the present embodiment not only quantity has lacked, and simultaneously because three bolts are in same direction, the disposable fitting operation of handled easily workman, meets ergonomics more.
Described seal body 100 also comprises the boss 102 that is positioned at described rubber parts 101 1 sides.No matter the quantity of boss 102 is several, all, in protection range of the present utility model, when the effect of boss 102 is subsequent modification or increases wire harness, can pass from this boss 102, and its material and rubber parts 101 are same.It is worth mentioning that, plastic base 104 is located at the periphery of seal body 100, i.e. the periphery of rubber parts 101 and boss 102 entirety, and the not periphery of rubber parts 101, same reason is also applicable to the shape of elastic packing frame 105.
In sum, the utility model has been introduced the plastic base of plastic material on the one hand, has both guaranteed the intensity of seal, meets the needs of construction bolt, has saved again the metallic support part in common design, and weight reduces greatly, has saved material cost simultaneously; On the other hand, the utility model has adopted elastic packing frame, utilizes its elasticity, can, by the sealing between locking realization and the fire compartment wall of bolt, avoid this complicated process means of in prior art, rubber parts itself being processed, has effectively reduced man-hour.The utility model, by improving structural design, adopting new material, simplifies the structure on the basis that meets its sealing property, has reduced cost, has improved the convenience of fitting operation.
