Above-mentioned, upper cover 11 and lower cover 13 are the metal material, its inside cable shielding layer connecting piece that all is equipped with, be equipped with first shielding jack catch 141 in upper cover 11, be equipped with second shielding jack catch 142 in lower cover 13, when arranging this connector in to the cable, first shielding jack catch 141 and second shielding jack catch 142 realize the joint to the shielding layer braided network of inside cable, thereby do not reach the mesh of the shielding layer braided network between the different cables of intercommunication to this cable, realized again better fixed to the cable, make the cable rigidity, the installation is firm, contact failure when having avoided the butt joint and to the influence of shielding effect.

Further, the first shielding claw 141 and the second shielding claw 142 each include a plurality of claw projection units 14 a;

in the upper cover 11 and the lower cover 13, the jaw protrusion units 14a are strip-shaped jaw protrusion units 14a which are perpendicular to the length direction of the unit to be sealed and connected.

As described above, the first shielding claw 141 and the second shielding claw 142 are correspondingly disposed in the upper cover 11 and the lower cover 13, wherein the shielding claw may be a plurality of claw protrusion units 14a, for example, 3 protrusion units in this embodiment, and each protrusion unit has a certain distance therebetween, and the protrusion units spaced by a certain distance can increase the fixing effect on the cable, so that the cable is fixed more firmly.

The jaw protrusion unit 14a has a protrusion with a certain height, and particularly, the height may be a height that can achieve contact with the shielding layer mesh grid of the corresponding cable and clamping to achieve fastening of the cable. For example, after the upper and lower covers 13 are closed by the intermediate seal member, the distance between the jaw protrusion unit 14a at the upper end and the jaw protrusion unit 14a at the lower end is not greater than the outer diameter of the cable (in the present embodiment, it is preferable that the distance between the jaw protrusion unit 14a at the end and the jaw protrusion unit 14a at the lower end is smaller than the outer diameter of the cable), so that after the cable is installed, the fixation of the cable is achieved by the pressing force of the jaw protrusion unit 14a in the upper and lower covers 13 to the engagement of the cable.

Also, in order to make the fixing of the cable more firm, the jaw protrusion units 14a in this embodiment are arranged in a strip shape, and the strip direction thereof is perpendicular to the direction of the cable, i.e., parallel with respect to the cross section of the cable, and each (strip) protrusion unit is spaced apart by a certain distance, so that the more firm fixing of the cable can be realized.

Further, the present embodiment proposes a new energy vehicle in which the multidirectional sealing connector 1 as described in the present embodiment is provided.
