In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0021] The preferred embodiments of the present invention are now further described in conjunction with the accompanying drawings. Figure 1 and Figure 2As shown, a male connector comprises a metal shell 10 and an insulating body 20 wrapped by the metal shell 10, a terminal assembly 30 is installed in the insulating body 20, a housing cavity 21 is arranged in the insulating body 20, a connecting port 22 is formed on one side of the insulating body 20, the connecting port 22 is used to insert other connector sockets, shielding sheets 100 are respectively arranged on the top and bottom of the housing cavity 21, the shielding sheet 100 comprises a shielding portion 110, the shielding portion 110 respectively covers the top and bottom of the housing cavity 21, snap arms 120 are respectively extended along the side walls between the top and bottom of the housing cavity 21 on both sides of the shielding portion 110 near one end of the connecting port 22, a bending portion 130 is formed between the snap arms 120 and the shielding portion 110, the snap arms 120 are staggered with each other and snap-fitted in a direction parallel to the side walls of the housing cavity 21.

[0022] When assembling this embodiment, the shielding sheet 100 is first installed on the top and bottom of the accommodating cavity 21, and the snap arms 120 on both sides of the shielding sheet 100 are respectively inserted tightly along the side walls between the top and bottom of the accommodating cavity 21, so that they are staggered and snap-fixed in a direction parallel to the side walls of the accommodating cavity 21. In this process, the shielding part 110 also covers the top and bottom of the accommodating cavity 21, thereby forming an electromagnetic shielding layer for the accommodating cavity 21, isolating the interior from the external environment, effectively reducing the leakage of electromagnetic radiation generated by the Type-C interface and its connecting lines, reducing interference with other surrounding electronic devices, and preventing effects on wireless communication, radio and television signals.

[0023] Compared with the prior art, the bending portion 130 described in the present application does not need to be elastic, and the shielding spring sheet 100 and the insulating body 20 do not need interference fit. When assembling the shielding sheet 100 and the insulating body 20, it is only necessary to insert the snap arms 120 on both sides of the shielding sheet 100 tightly along the side walls between the top and the bottom of the accommodating cavity 21, so that they are staggered and snap-fixed in a direction parallel to the side walls of the accommodating cavity 21. In this way, whether the shielding sheet 100 and the insulating body 20 are firmly fixed or not has nothing to do with the material of the shielding sheet 100 itself, and the shielding sheet 100 and the insulating body 20 will not be separated due to damage or aging of the insulating body material, thereby greatly improving the electromagnetic shielding performance and reliability of the present application.

[0024] On the basis of the above embodiment, as Figure 2As shown, when the snap arms 120 are intertwined with each other on the side walls of the accommodating cavity 21, the ends of the snap arms 120 away from the bending portion 130 are bent outwards toward each other to form snap portions 121, and snap fixation is formed between the snap portions 121. When the snap arms 120 move outwards along the side walls of the accommodating cavity 21, the snap portions 121 will abut against each other on the side walls of the accommodating cavity 21 to form a snap form, thereby ensuring that the shielding sheet 100 and the insulating body 20 will not detach from each other.

[0025] In some embodiments, Figure 2 As shown, an inclined surface 121a is provided at the end of the buckle portion 121, and the inclined surfaces 121a are parallel to each other. Since the buckle arms 120 are fixed by interlaced buckling, during the assembly process, when the buckle arms 120 move toward each other along the side walls of the accommodating cavity 21, the buckle arms 120 will first contact each other and deflect in the opposite direction. The inclined surface 121a can help the buckle portion 121 to reduce the deflection angle during the contact process, thereby preventing the buckle arms 120 from being deflected too much during the assembly process, thereby preventing the buckle arms 120 from being broken due to the risk of breaking.

[0026] In some embodiments, Figure 2 As shown, a groove 121b is provided on the side of the buckle arm 120 away from the buckle portion 121. Even if a slope 121a is provided at the end of the buckle portion 121, the buckle arm 120 will still deflect during the assembly process. The groove 121b is provided on the side of the buckle arm 120 away from the buckle portion 121, which can increase the buckle arm 120's ability to withstand deflection, thereby further improving the safety of assembly.

[0027] On the basis of the above embodiments, Figure 2 and Figure 3As shown, a protrusion 121c is arranged on the end face of the snap arm 120 facing outward, and an abutment portion 23 is arranged on the insulating body 20 opposite to the protrusion 121c. When the snap arm 120 moves toward each other along the side wall of the accommodating cavity 21, the abutment portion 23 compresses the protrusion 121c, so that the snap arm 120 can squeeze the two sides of the accommodating cavity 21. In this way, after the snap arm 120 is snap-fastened in the parallel direction of the side wall of the accommodating cavity 21, the abutment portion 23 compresses the protrusion 121c, so that the snap arm 120 also clamps the insulating body 20 in the vertical direction of the side wall of the accommodating cavity 21, thereby making the fixing between the shielding sheet 100 and the insulating body 20 more secure. Preferably, there is a first redundant space 122 between the snap parts 121, so that under normal conditions, the snap parts 121 do not contact each other. Preferably, the snap arms 120 also clamp the insulating body 20 in the vertical direction of the side wall of the accommodating cavity 21 to ensure the fixation between the shielding sheet 100 and the insulating body 20. When the shielding sheet 100 encounters an external force parallel to the side wall of the accommodating cavity 21, the snap parts 121 thereof contact each other to form a snap fixation, thereby providing a second guarantee for the fixation between the shielding sheet 100 and the insulating body 20.

[0028] On the basis of the above embodiment, as Figure 4 As shown, the terminal assembly 30 includes an upper terminal group 31 and a lower terminal group 32, and the upper terminal group 31 and the lower terminal group 32 each include an elastic connecting portion 31a, a main body portion 31b and a welding portion 31c which are arranged in sequence, and the elastic connecting portion 31a is arranged in the accommodating cavity 21. When inserted into other connector sockets, the elastic connecting portion 31a is used to form an electrical connection with other connector sockets, and the welding portion 31c is used to be welded to a circuit board.

[0029] On the basis of the above embodiment, as Figure 4 As shown, a plurality of accommodating grooves 21a are respectively provided at the top and bottom of the accommodating cavity 21, and the accommodating grooves 21a penetrate the top and bottom of the accommodating cavity 21 in the vertical direction. The number of the accommodating grooves 21a is consistent with the number of terminals in the upper terminal group 31 and the lower terminal group 32, and the positions of the accommodating grooves 21a correspond to the elastic connecting parts 31a in the upper and lower parts. When the elastic connecting parts 31a form an electrical connection with other connector sockets, the elastic connecting parts 31a will be tilted toward the top and bottom of the accommodating cavity 21 so as to be accommodated in the accommodating grooves 21a, thereby avoiding the elastic connecting parts 31a from being squeezed and broken when they contact with other connector sockets.

[0030] On the basis of the above embodiments, Figure 3 and Figure 5As shown, a plurality of first elastic portions 111 are provided on one side of the shielding portion 110 close to the connection port 22. The first elastic portions 111 bend toward the accommodating cavity 21. When other connector sockets form an electrical connection, the first elastic portions 111 contact with the connector sockets and bend outward, thereby avoiding a phase change of the shielding portion 110 as a whole.

[0031] On the basis of the above embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, a through groove 112 is provided on one side of the first elastic portion 111, and an insulating shielding plate 113 is covered on the through groove 112, and the insulating shielding plate 113 covers the outside of the receiving groove 21a, so that when the elastic connecting portion 31a is squeezed into the receiving groove 21a, it can be avoided that the elastic connecting portion 31a passes through the insulating body 20 and contacts the metal shell 10 to form a short circuit, and second elastic portions 114 are provided at both ends of the insulating shielding plate 113, and the second elastic portion 114 is bent toward the outside of the receiving cavity 21, so that when the metal shell The insulating body 20 is wrapped by the metal shell 10, and the second elastic part 114 forms a second redundant space 114a between the metal shell 10 and the insulating body 20. In this way, even if the elastic connecting part 31a is squeezed into the accommodating groove 21a and passes through the insulating body 20 to contact the insulating shielding plate 113, the insulating shielding plate 113 still has a part of space to move upward, thereby avoiding excessive contact between the elastic connecting part 31a and the insulating shielding plate 113, thereby causing damage to the elastic connecting part 31a and the insulating shielding plate 113.

[0032] In some embodiments, such as Figure 5 , Figure 6 and Figure 7As shown, the insulating shielding plate 113 includes a covering end 113a, a slot 113b is provided at one end of the covering end 113a, a first inclined portion 113c is provided at the top of the slot 113b, a plug plate 112a is provided inside the through slot 112, and a second inclined portion 112b is provided at the top of the plug plate 112a. When the insulating shielding plate 113 covers the through slot 112, the plug plate 112a is inserted into the slot 113b, and the first inclined portion 113c and the second inclined portion 112b are in contact, so that when the elastic connecting portion 31a is squeezed into the accommodating groove 21a and passes through the insulating body 20 to contact the insulating shielding plate 113, due to the The plug board 112a is inserted into the slot 113b, so the insulating shielding plate 113 will not be lifted up as a whole, but one end will be tilted upward, and the tilting angle depends on the angle of cooperation between the first inclined portion 113c and the second inclined portion 112b. In this way, when the elastic connecting portion 31a is not in contact with the insulating shielding plate 113, the insulating shielding plate 113 will still cover the slot 113b without moving its position. In addition, preferably, the thickness h of the covering end 113a is between 0.08 and 0.12 mm. This size can ensure the insulating shielding effect of the insulating shielding plate 113, and can also ensure that the second redundant space 114a has enough space to allow the insulating shielding plate 113 to tilt upward.

[0033] The details of the exemplary embodiments described above are not limited to the embodiments described above, and the invention may be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive in all respects, and the scope of the invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
