Description

Technical Field

[0001] The present invention relates to the field of connectors, and more particularly to a male connector. Background Art

[0002] A shielding shrapnel is installed outside the insulating body of a Type-C connector. The shielding shrapnel, also known as an EMI shielding sheet, functions to form an electromagnetic shielding layer to isolate the internal circuit from the external environment, effectively reducing the electromagnetic radiation leakage generated by the Type-C interface and its connection lines, reducing interference with other surrounding electronic devices, preventing the impact on signals such as wireless communication and radio and television, and enabling the device to meet relevant electromagnetic compatibility standards.

[0003] Existing shielding shrapnels usually have shielding parts covering the top and bottom of the insulating body and pins for plugging on both sides of the insulating body. A bending part is formed between the shielding part and the pins. Whether the fixing method between the shielding shrapnel and the insulating body is by interference fit or by clamping the insulating body on both sides with the pins, it is an interference fit between the metal shielding shrapnel and the insulating body, which is likely to cause damage to the relatively soft plastic, resulting in the failure of the buckle position, thus affecting the function, production cost and production efficiency of the product. Summary of the Invention

[0004] To solve the above problems, the present invention provides a male connector, including a metal shell and an insulating body wrapped by the metal shell. A terminal assembly is installed in the insulating body. A receiving cavity is provided in the insulating body. A connection port is formed on one side of the insulating body for the receiving cavity. Shielding sheets are respectively provided at the top and bottom of the receiving cavity. The shielding sheet includes a shielding part. The shielding parts are respectively provided at the top and bottom of the receiving cavity. On both sides of the shielding part near one end of the connection port, buckle arms extend along the side wall between the top and bottom of the receiving cavity. A bending part is formed between the buckle arm and the shielding part. The buckle arms are interlaced with each other and form a buckle fixation in the direction parallel to the side wall of the receiving cavity.

[0005] Furthermore, when the buckle arms are interlaced with each other on the side wall of the receiving cavity, the ends of the buckle arms away from the bending part are respectively bent outward and oppositely to form buckle parts, and a buckle fixation is formed between the buckle parts.

[0006] Furthermore, inclined surfaces are provided at the ends of the buckle parts, and the inclined surfaces are parallel to each other.

[0007] Furthermore, grooves are provided on the side of the buckle arm away from the buckle part.

[0008] Furthermore, a convex portion is provided on the end face of the buckle arm facing outward, and an abutting portion corresponding to the position of the convex portion is provided on the insulating body. When the buckle arms move toward each other along the side wall of the receiving cavity, the abutting portion presses on the convex portion, enabling the buckle arms to squeeze both sides of the receiving cavity, and a first redundant space is formed between the buckle portions.

[0009] Furthermore, the terminal assembly includes an upper terminal group and a lower terminal group. Both the upper terminal group and the lower terminal group include an elastic connecting portion, a main body portion, and a welding portion arranged in sequence, and the elastic connecting portion is disposed in the receiving cavity.

[0010] Furthermore, a plurality of receiving grooves are respectively provided at the top and bottom of the receiving cavity. The receiving grooves penetrate through the top and bottom of the receiving cavity in the vertical direction. The number of the receiving grooves is the same as the number of terminals in the upper terminal group and the lower terminal group, and the positions of the receiving grooves correspond to the elastic connecting portions up and down.

[0011] Furthermore, a plurality of first elastic portions are provided on the side of the shielding portion close to the connection port, and the first elastic portions bend toward the receiving cavity.

[0012] Furthermore, a through groove is provided on one side of the first elastic portion, and an insulating shielding plate is covered on the through groove. The insulating shielding plate covers the outside of the receiving groove. Second elastic portions are provided at both ends of the insulating shielding plate, and the second elastic portions bend toward the outside of the receiving cavity. The second elastic portions then form a second redundant space between the metal shell and the insulating body.

[0013] Furthermore, the insulating shielding plate includes a covering end. A slot is provided at one end of the covering end, a first inclined portion is provided at the top of the slot, a plug board is provided inside the through groove, and a second inclined portion is provided at the top of the plug board. When the insulating shielding plate covers the through groove, the plug board is inserted into the slot, and the first inclined portion and the second inclined portion are in contact with each other. The thickness of the covering end is between 0.08 and 0.12 millimeters.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the present application, the bent portion does not need to be elastic, and there is no need for interference fit between the shielding elastic piece and the insulating body. When assembling the shielding piece and the insulating body, it is only necessary to insert the buckle arms on both sides of the shielding piece tightly along the side wall between the top and bottom of the accommodating cavity respectively, so that they are staggered and buckled and fixed in the direction parallel to the side wall of the accommodating cavity. In this way, whether the fixing between the shielding piece and the insulating body is firm or not has nothing to do with the material of the shielding piece itself, and the detachment between the shielding piece and the insulating body will not occur due to damage or aging of the insulating body material, thus greatly improving the electromagnetic shielding performance and reliability of the present application.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] Now, with reference to the accompanying drawings, a further description will be made of the preferred embodiments of the present invention. Figure 1 and Figure 2 As shown, a male connector includes a metal housing 10 and an insulating body 20 wrapped by the metal housing 10. A terminal assembly 30 is installed in the insulating body 20. A receiving cavity 21 is provided in the insulating body 20. A connection port 22 is formed on one side of the insulating body 20 for inserting other female connectors. Shielding sheets 100 are respectively provided at the top and bottom of the receiving cavity 21. The shielding sheet 100 includes a shielding portion 110 which respectively covers the top and bottom of the receiving cavity 21. At both sides of the shielding portion 110 near one end of the connection port 22, buckle arms 120 extend towards the side wall between the top and bottom of the receiving cavity 21. A bending portion 130 is formed between the buckle arms 120 and the shielding portion 110. The buckle arms 120 are staggered with each other and form a buckle fixation in the direction parallel to the side wall of the receiving cavity 21.

[0032] When assembling this embodiment, first install the shielding sheets 100 at the top and bottom of the receiving cavity 21, and insert the buckle arms 120 on both sides of the shielding sheet 100 along the side wall between the top and bottom of the receiving cavity 21 closely, so that they are staggered and form a buckle fixation in the direction parallel to the side wall of the receiving cavity 21. During this process, the shielding portion 110 also respectively covers the top and bottom of the receiving cavity 21, thereby forming an electromagnetic shielding layer for the receiving cavity 21, isolating the inside from the external environment, effectively reducing the leakage of electromagnetic radiation generated by the Type-C interface and its connection lines, reducing the interference to other surrounding electronic devices, and preventing the influence on signals such as wireless communication and radio and television.

[0033] Compared with the prior art, the bending portion 130 described in the present application does not need to be elastic, and there is no need for interference fit between the shielding elastic piece 100 and the insulating body 20. When assembling the shielding piece 100 and the insulating body 20, it is only necessary to insert the buckle arms 120 on both sides of the shielding piece 100 tightly along the side walls between the top and bottom of the accommodating cavity 21 respectively, so that they are staggered and buckled and fixed in the direction parallel to the side wall of the accommodating cavity 21. In this way, whether the fixing between the shielding piece 100 and the insulating body 20 is firm or not has nothing to do with the material of the shielding piece 100 itself, and the shielding piece 100 and the insulating body 20 will not become separated due to damage or aging of the insulating body material, thus greatly improving the electromagnetic shielding performance and reliability of the present application.

[0034] Furthermore, on the basis of the above embodiments, as Figure 2 shown, when the buckle arms 120 are staggered with each other on the side wall of the accommodating cavity 21, the ends of the buckle arms 120 far away from the bending portion 130 are respectively bent outward and oppositely to form buckle portions 121, and the buckle portions 121 are buckled and fixed with each other. When the buckle arms 120 move outward along the side wall of the accommodating cavity 21 respectively, the buckle portions 121 will abut against each other on the side wall of the accommodating cavity 21 to form a buckle form, thus ensuring that the shielding piece 100 and the insulating body 20 will not be separated from each other.

[0035] In some embodiments, as Figure 2 shown, a slope 121a is provided at the end of the buckle portion 121, and the slopes 121a are parallel to each other. Since the buckle arms 120 are buckled and fixed with each other, during the assembly process, when the buckle arms 120 move toward each other along the side wall of the accommodating cavity 21 respectively, the buckle arms 120 will first contact each other and then deflect in the reverse direction. The slope 121a can help the buckle portion 121 reduce the deflection angle during the contact process, so as to prevent the deflection angle of the buckle arm 120 from being too large during the assembly process and thus avoid the risk of fracture.

[0036] In some embodiments, as Figure 2 shown, a groove 121b is provided on the side of the buckle arm 120 away from the buckle portion 121. Since even if a slope 121a is provided at the end of the buckle portion 121, during the assembly process, the buckle arm 120 will still deflect. By providing a groove 121b on the side of the buckle arm 120 away from the buckle portion 121, the bearing capacity of the buckle arm 120 for deflection can be increased, thereby further improving the safety of the assembly.

[0037] Furthermore, on the basis of the above embodiments, in combination with 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.

[0038] 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.

[0039] 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.

[0040] On the basis of the above embodiments, Figure 3 and Figure 5As shown, several first elastic parts 111 are arranged on the side of the shielding part 110 close to the connection port 22. The first elastic parts 111 bend towards the accommodation cavity 21. When other connector female seats form electrical connection, the first elastic parts 111 contact the connector female seat and thus bend outwards, so as to avoid the overall phase change of the shielding part 110.

[0041] Furthermore, on the basis of the above embodiments, as Figure 5 , Figure 6 and Figure 7 shown, a through groove 112 is arranged on one side of the first elastic part 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 accommodation groove 21a. This can avoid that when the elastic connecting part 31a is squeezed into the accommodation groove 21a, it passes through the insulating body 20 and contacts the metal shell 10 to form a short circuit. Second elastic parts 114 are arranged at both ends of the insulating shielding plate 113. The second elastic parts 114 bend towards the outside of the accommodation cavity 21. In this way, when the insulating body 20 wrapped by the metal shell 10, the second elastic parts 114 still form a second redundant space 114a between the metal shell 10 and the insulating body 20. In this way, even when the elastic connecting part 31a is squeezed into the accommodation groove 21a and contacts the insulating shielding plate 113 when passing through the insulating body 20, the insulating shielding plate 113 still has a part of upward movement space, so as to avoid 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.

[0042] In some embodiments, as Figure 5 , Figure 6 and Figure 7As shown, the insulation 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. An insertion plate 112a is provided inside the through slot 112. A second inclined portion 112b is provided at the top of the insertion plate 112a. When the insulation shielding plate 113 covers the through slot 112, the insertion plate 112a is inserted into the slot 113b, and the first inclined portion 113c is in contact with the second inclined portion 112b. In this way, when the elastic connection portion 31a is squeezed into the receiving groove 21a and contacts the insulation shielding plate 113 through the insulation body 20, since the insertion plate 112a is inserted into the slot 113b, the insulation shielding plate 113 will not be lifted as a whole, but one end will tilt upward, and the tilting angle depends on the matching angle between the first inclined portion 113c and the second inclined portion 112b. In this way, when the elastic connection portion 31a is not in contact with the insulation shielding plate 113, the insulation 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 millimeters. This dimension can ensure the insulation shielding effect of the insulation shielding plate 113 and also ensure that there is enough space in the second redundant space 114a for the insulation shielding plate 113 to tilt upward.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
