Detailed Description

The present invention will be further explained with reference to specific examples, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications to the various equivalent forms of the invention, which may occur to those skilled in the art upon reading the present invention, fall within the scope of the appended claims.

As shown in fig. 1, a cable heating assembly includes a cable unit 4, a connection box 8, one or more connection units 1, and one or more wire-shaped cable heating units 7. The linear cable heating unit 7 comprises at least one heating body branch 9 and is electrically connected to the cable unit 4 by one or more connection units 1.

One or more of the connection units 1 comprises 4

splice connection units

11 and 1 integral connection unit 12. Each of the 4 splicing type connection units 11 includes a first connection unit 111 and a second connection unit 112, the second connection unit 112 is common to the 4 splicing type connection units 11, wherein the first connection units 111 of the 4 splicing type connection units 11 share a first connection point 2 at the same end to be electrically connected with the common second connection unit 112, and the first connection point 2 is coated with a first injection molding layer 3. As shown in fig. 2, the first injection layer 3 is coated in a specific manner that one end of the first connection unit 111 is connected to one end of the second connection unit 112 by welding or riveting to form the first connection point 2, and low-pressure injection packaging is performed outside the first connection point 2.
