Embodiment 1

[0028] The tail cover for plastic sealing of the present invention will be further described in detail below in conjunction with the above-mentioned accompanying drawings:

[0029] The tail cover for plastic packaging is designed with 1.1-anti-decoupling, 1.2-anti-slip groove on the outer wall, 1.3-anti-slip groove on the inner wall, and 1.4-shielding groove.

[0030] The anti-decoupling 1.1 is a barb structure. After plastic sealing, the barb structure is embedded in the plastic sealing rubber to hang the plastic sealing rubber. The anti-skid groove 1.2 on the outer wall is a two-groove structure. The tensile strength of the plastic sealant; the anti-slip groove 1.3 on the inner wall is a groove structure, which improves the bonding strength between the potting glue in the tail cover and the tail cover, and protects the solder joints and the base of the connector; the shielding groove 1.4 is a groove structure, through welding and The shielding layer 1.7 realizes 360° shell c...

Embodiment 2

[0032] Embodiment 2: as figure 1 : The tail cover is composed of a large diameter section, a gradual transition section and a small diameter section. An inner wall anti-slip groove 1.3 is provided on the inner wall of the tail cover, an anti-detachment hook 1.1 and an outer wall anti-slip groove 1.2 are provided on the outer wall of the large diameter section of the tail cover, and a shielding groove 1.4 is provided on the small diameter section of the tail cover. There are three anti-skid grooves 1.3 on the inner wall, and two anti-skid grooves 1.2 on the outer wall.

[0033] Install the cable 1.9 in the outlet of the small-diameter section of the tail cover for plastic packaging. First, the shielding layer of the cable 1.9 is turned out and extended to the shielding slot 1.4, and then wound with silver-plated copper wire and tinned with high-temperature solder to achieve 360° shielding. ° Connect the shell. The diameter of the outlet of the tail cover is designed according...

Abstract

The invention discloses a tail cover for plastic package, the inner wall surface of the tail cover is provided with an inner wall antiskid groove 1.3, the outer wall surface of the large-diameter section of the tail cover is provided with an anti-falling hook 1.1 and an outer wall antiskid groove 1.2, and the small-diameter section of the tail cover is provided with a shielding groove 1.4. The structure is a universal structure, the thread end can be designed according to thread matching of a matched connector, and the diameter of the wire outlet end is designed according to the diameter of a selected cable. When a user plugs and pulls the connector in the using process, the plastic package part serves as a stress part, the tail cover can increase the bonding area of the connector and plastic package rubber, and the bonding performance of the plastic package rubber and the connector is improved through the design of the mousing hook and the anti-skid groove.

Description

technical field [0001] The invention belongs to the technical field of cable plastic sealing, and in particular relates to a tail cover for plastic sealing and a corresponding plastic sealing structure. Background technique [0002] The so-called plastic-encapsulated cable refers to the use of injection molding to wrap the connecting part of the cable and the connector with a plastic sealing material, and to ensure that the plastic sealing part has a certain degree of flexibility. The plastic sealing process is usually carried out under the conditions of high pressure and high temperature (30MPa~50MPa, 170℃~190℃). For some special connectors, the high temperature and high pressure during the plastic sealing process will damage the connector, and usually the structure of the connector limits the plastic sealing. When the available plastic cover is small, the adhesion between the plastic sealant and the connector is poor, and the plastic seal will fall off under a large pullin...
