And the PVC has good bondability with the glue, so that the water blocking material is filled between the sealing main body 31 and the cabinet 200 and between the sealing main body 31 and the cable 10, thereby further improving the sealing and waterproof performance of the connection harness 100. Of course, the sealing body 31 may be made of other materials than PVC, such as XL-PVC and XL-PE materials.
