Further, the material used for injection molding was a thermoplastic vulcanizate with shore hardness of 49A, the first stage temperature: at 210 ℃; temperature in the second stage: 215 ℃ of; temperature in the third stage: 220 ℃; temperature in the fourth stage: 215 ℃ is adopted. The molding pressure is 40Kg/cm at the first time ² The second pressure is 30Kg/cm ² The total pressure is 100Kg/cm ² Cooling time 3S, injection time 2S.

It should be noted that, in the second technical solution of the embodiment, the structure of the second ferrule 32 is not limited to only one guiding portion 321, one card slot 322, and one protrusion 323, and may be multiple, and when there are multiple guiding portions 321, card slots 322, and protrusions 323, the card slots 322 and the protrusions 323 with different sizes may be arranged according to actual requirements, so as to ensure that the matching relationship between the bottom wall of the card slot 322 and the preset hole meets the requirements of dust prevention and water prevention.
