Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the utility model is used, and are only for convenience of describing the present invention or simplifying the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed or operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the connection may be direct or indirect via an intermediate medium, and may be a communication between the two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1-4, the utility model relates to a car wiring harness connects uses double-deck pyrocondensation pipe, including inlayer plastic pipe 3 and outer pyrocondensation pipe 2, the outer wall middle part of outer pyrocondensation pipe is equipped with round arch 4, corresponds on the inner wall of outer pyrocondensation pipe the arch is equipped with round indent annular a5, corresponds on the inner wall of inlayer plastic pipe the arch is equipped with round indent annular b 6.
Further, in this embodiment, the transverse cross-sections of the protrusion, the concave ring groove a, and the concave ring groove b are all trapezoidal structures.
Furthermore, in this embodiment, the lengths of the ends at both ends of the outer heat shrinkable tube are greater than the lengths of the ends of the corresponding inner plastic tube.
Further, in this embodiment, the two ends of the outer heat shrinkable tube are both conical structures 1.
Further, in this embodiment, the inner plastic pipe and the outer heat shrinkable pipe are formed by hot extrusion and compounding.
The positions of the product bulge, the inner concave ring groove a and the inner concave ring groove b in the embodiment are all corresponding and are positioned on an upper line and a lower line.
The utility model discloses a double-deck pyrocondensation pipe, in the use, specifically be so operated: firstly the utility model discloses wiring harness joint position is aimed at to indent annular b in the product, because the joint position common diameter of pencil is a little bigger, consequently just block in indent annular b, carry out heat treatment to outer layer pyrocondensation pipe again, make it be heated the shrink, and arch and indent annular a are because the part is convex form, the local shrink of being heated here is bigger, consequently the cladding parcel that here connects to the pencil can be bigger tighter more closely, sealed effect can be better, safe use to car electrical component has played fine guarantee effect.
The utility model discloses a carry out local institutional advancement to traditional car pencil pyrocondensation pipe for the connection cladding at pencil joint position reaches the sealed effect of best, and this uses safely for car pencil provides the powerful guarantee, has fine in-service use and spreading value.
