Then, the adhesive is cured to form a solid adhesive layer 20. The coating of the adhesive on the inner surface 11 of the outer sheath member 10 may be performed by applying the adhesive with a tool and then coating the adhesive on the inner surface 11 of the outer sheath member 10. In another embodiment, the step of forming the solid adhesive layer 20 on the inner surface 11 may also be spraying the adhesive on the inner surface 11 of the outer sleeve 10, and then curing the adhesive to form the solid adhesive layer 20, wherein the step of spraying the adhesive on the inner surface 11 of the outer sleeve 10 may be spraying the adhesive on the inner surface 11 of the outer sleeve 10 by using a nozzle. The adhesive can be a molten adhesive or an adhesive solution.
The step of forming the solid adhesive layer 20 on the inner surface 11 of the outer sleeve 10 further comprises: the adhesive is cooled to form the solid adhesive layer 20, i.e., the adhesive formed on the inner surface 11 of the outer sleeve 10 by coating or spraying is cooled to solidify the adhesive to form the solid adhesive layer 20. The step of cooling the adhesive to form the solid adhesive layer 20 is to first stand the outer sleeve 10 after coating or spraying the adhesive, so that the adhesive on the inner surface 11 of the outer sleeve 10 is naturally cooled and solidified to form the solid adhesive layer 20. In another embodiment, the step of cooling the adhesive to form the solid adhesive layer 20 uses a fan or the like to generate an air flow to accelerate the curing of the adhesive after cooling.

Referring back to fig. 1, after completion of step S3, the flow proceeds to step S4. In step S4, the connector body 30 and the outer sleeve 10 are bonded by the molten adhesive layer 20'. Referring to fig. 6, the molten adhesive layer 20' fills the gap between the connector body 30 and the outer sleeve 10 by its fluidity and adheres to the outer surface of the connector body 30 and the inner surface 11 of the outer sleeve 10, thereby functioning to adhere the connector body 30 and the outer sleeve 10.
After the molten adhesive layer 20' is adhered to the connector body 30 and the outer sleeve member 10, the molten adhesive layer 20 is further cooled. The step of cooling the molten adhesive layer 20 'is to stand the outer sleeve 10 and the connector body 30 to naturally cool the molten adhesive layer 20'.
