Three of the positioning holes of each positioning ring 8 are fixedly connected with first reinforcing ribs 9, and the other three positioning holes of each positioning ring 8 are fixedly connected with second reinforcing ribs 10. The first reinforcing ribs 9 and the second reinforcing ribs 10 are both located in the receiving groove 7 of the protective sleeve 3. Two groups of reinforcing grooves 11 are provided at both the front and rear ends of the protective sleeve 3. Two guiding plates 12 are fixedly connected to both the front and rear inner sides of the protective sleeve 3. A group of reinforcing shafts 13 are fixedly connected to the sides of the guiding plates 12 close to the protective sleeve 3. The reinforcing shafts 13 are all located in the reinforcing grooves 11 of the protective sleeve 3. A heat shrinkable sleeve 14 is sleeved outside the protective sleeve 3.
[0027] The two wire harness connectors 2 are symmetrically distributed front and back. There are four guiding plates 12. Both the upper and lower sides of the wire harness connectors 2 are in contact with the guiding plates 12. The wire harness connectors 2 and the guiding plates 12 are both provided with connection holes, and the connection holes of the guiding plates 12 are the same size as those of the wire harness connectors 2. The guiding plates 12 and the wire harness connectors 2 can be connected to electrical equipment together; the protective sleeve 3 is a cylindrical rubber sleeve. Grooves are provided at both the front and rear ends of the protective sleeve 3. A cut is provided at the left end of the protective sleeve 3. The engaging grooves 4 of the protective sleeve 3 are all the same shape as the engaging blocks 5. The engaging grooves 4 communicate with the positioning groove 6, and the engaging blocks 5 can be inserted into the engaging grooves 4; the multiple positioning rings 8 are equidistantly distributed in the front and rear directions. The positioning rings 8 are all rubber rings. Cuts are provided at the left ends of the positioning rings 8. Each positioning ring 8 is provided with six positioning holes penetrating through in the front and rear directions. The first reinforcing ribs 9 and the second reinforcing ribs 10 can be fixed through the positioning rings 8; the first reinforcing ribs 9 and the second reinforcing ribs 10 are both carbon steel wire shafts. There are multiple groups of the first reinforcing ribs 9 and the second reinforcing ribs 10. Each group of the first reinforcing ribs 9 and the second reinforcing ribs 10 has three.

The reinforcing shafts 13 can firmly connect the protective sleeve 3 and the guiding plates 12.
[0028] Workflow: The wire harness body 1 and the wire harness connector 2 of this wire harness are both existing components. When this wire harness is produced, first, a plurality of first reinforcing ribs 9 and second reinforcing ribs 10 are fixed on the positioning ring 8, and then the protective sleeve 3 is produced by injection molding with a mold. When the protective sleeve 3 is injection molded, the positioning ring 8, the first reinforcing rib 9, the second reinforcing rib 10, the guide plate 12, and the reinforcement shaft 13 are placed in the mold. Combining with the mold can enable the protective sleeve 3 to generate the engaging groove 4, the positioning groove 6, the accommodating groove 7, and the reinforcement groove 11, and thus the positioning ring 8, the first reinforcing rib 9, the second reinforcing rib 10, the guide plate 12, and the reinforcement shaft 13 can be fixed. The left end of the protective sleeve 3 is provided with a notch, so the protective sleeve 3 can be sleeved outside the wire harness body 1, enabling the engaging block 5 to be inserted into the engaging groove 4. Finally, the heat shrinkable sleeve 14 is sleeved outside the protective sleeve 3. The heat shrinkable sleeve 14 has heat shrinkability.
