[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In the field of modern electronic equipment and communications, plugs, as an important connection component, are widely used in various scenarios such as mobile phones, computers, audio and video equipment, and plugs can be used to transmit electrical energy or data. In the prior art, the shell of the plug is generally directly mounted on the core body, but whether the shell is connected to the core body by assembly or by injection molding, the shell is easily broken due to the weak connection between the shell and the core body, especially after long-term use. In addition, during the use of the plug, the user's plugging and unplugging habits, usage methods, etc. will also affect the performance of the plug. Frequent plugging and unplugging, excessive bending, etc. may cause fatigue damage to the connection of the shell, accelerate the process of shell rupture, and seriously affect product quality and user experience.

[0038] To solve the above technical problems, Figures 1 to 8 As shown, the present application provides a plug 100 , which includes a shell 110 , a core 120 and a sheet metal part 130 .

[0039] like Figure 1 , Figure 2 as well as Figure 5 As shown, the housing 110 defines a housing cavity 111, and the housing 110 is further provided with a first opening 112 and a second opening 113 respectively communicating with the housing cavity 111. The housing 110 can be configured to contain any suitable hard plastic such as polyurethane, polystyrene, polyphenylene sulfide, polycarbonate, polyamide or polyoxymethylene, so that the housing 110 can protect the core 120 and reduce the risk of damage to the internal electrical connection components of the core 120. The shape of the housing cavity 111 of the housing 110 can be set according to the actual shape, size and damage resistance requirements of the core 120.

[0040] like Figure 2 as well as Figure 5As shown, the core 120 has a first end 121 and a second end 122 arranged opposite to each other, the first end 121 has an electrical connection terminal 1211, and the second end 122 has a connecting wire 1221. The housing 110 is sleeved on the core 120, the first end 121 is provided with a first opening 112, and the second end 122 is provided with a second opening 113 along a first direction. The first end 121 is used to connect with the terminal device. According to different connection requirements, the first end 121 can be configured as a Type-A interface (Universal Serial Bus Type A interface), a Type-B interface (Universal Serial Bus Type B interface), a Type-C interface (Universal Serial Bus Type C interface), a Micro-USB interface (Micro Universal Serial Bus interface), an HDMI interface (High Definition Multimedia Interface), a VGA interface (Video Graphics Array Interface), a DVI interface (Digital Video Interface), a Lightning interface (Lightning interface) or a DisplayPort interface (Display Port interface) and any other suitable interface. The second end 122 is provided with a connecting wire 1221, and the setting of the cable can be selected according to the transmission requirements of the first end 121, which will not be repeated here. The direction in which the first end 121 passes through the first opening 112 may be parallel to the first direction or may cross the first direction. Preferably, the first end 121 and the second end 122 may be arranged opposite to each other along the first direction, and correspondingly, the first opening 112 and the second opening 113 may also be arranged opposite to each other along the first direction, and the core 120 may pass from the first opening 112 to the second opening 113 along the first direction.

[0041] like Figure 2 as well as Figure 3As shown, the sheet metal part 130 is sleeved on the second end 122 and connected to the end of the shell 110 away from the first opening 112. Along the direction perpendicular to the first direction, the end of the sheet metal part 130 close to the first opening 112 overlaps with the end of the shell 110 defining the second opening 113. In other words, the sheet metal part 130 is provided at one end of the shell 110 defining the second opening 113. The overlap of the end of the sheet metal part 130 and the end of the shell 110 can effectively improve the strength of the connection between the shell 110 and the core 120, and reduce the risk of the shell 110 breaking during use. The first direction is the axial direction of the core 120, the direction around the axis parallel to the first direction is the circumferential direction, and the direction perpendicular to the first direction is the radial direction. The sheet metal part 130 is sleeved on the core 120. Along the circumferential direction, the sheet metal part 130 can be continuous, can be a sheet metal part with an opening, or can be a plurality of sheet metal parts arranged at intervals along the circumferential direction. Preferably, along the first direction, the length of the sheet metal part 130 is not greater than the length of the shell 110, and the length of the sheet metal part 130 can be any suitable length such as 1 / 3, 1 / 4 or 1 / 5 of the length of the shell 110. The length of the sheet metal part 130 is shorter than the length of the shell 110. On the one hand, it can reduce the use of sheet metal materials and reduce the overall weight of the plug 100. On the other hand, the length of the shell 110 and the sheet metal part 130 can be substantially reasonable. The shorter length of the sheet metal part 130 can effectively reduce the risk of cracking of the shell 110 while maintaining the aesthetics and feel of the adapter. The sheet metal part 130 can be configured as any suitable metal sheet such as titanium alloy, carbon steel, stainless steel, aluminum alloy, cold-rolled steel plate, galvanized steel plate, copper or copper alloy. Preferably, the sheet metal part 130 is configured as a titanium alloy. Titanium alloy has high strength, good corrosion resistance, light weight, and is easy to process. The sheet metal part 130 is configured as a titanium alloy, which can effectively improve the reliability, durability and service life of the plug 100.

[0042] In a direction perpendicular to the first direction, the sheet metal part 130 and the housing 110 are overlapped. Specifically, to improve the connection stability between the sheet metal part 130 and the housing 110, the housing 110 may define a slot, and the sheet metal part 130 may be inserted into the slot of the housing 110, or the sheet metal part 130 may define a slot, and the housing 110 may be inserted into the slot of the sheet metal part 130. Figure 7 As shown, in some embodiments, the shell 110 has a third end 114, and the third end 114 defines a second opening 113 and a first slot 1141. The sheet metal part 130 has a first protrusion 131, and the first protrusion 131 is inserted into the first slot 1141. In a direction perpendicular to the first direction, the first slot 1141 can be connected to the second opening 113, and the shell 110 can also be provided with a plate to space the first slot 1141 from the second opening 113. In other words, the overlapping portion of the sheet metal part 130 and the shell 110 can directly abut against the core 120, or can be spaced from the core 120. Figure 8As shown, in some embodiments, the housing 110 has a third end 114, the third end 114 defines a second opening 113, the third end 114 also has a second protrusion 1142, the sheet metal 130 defines a second slot 132, and the second protrusion 1142 is inserted into the second slot 132. Similarly, along a direction perpendicular to the first direction, the second slot 132 may also be connected to or spaced from the second opening 113. In some embodiments, the housing 110 may be provided with both the first slot 1141 and the second protrusion 1142, and accordingly, the sheet metal 130 may be provided with both the second slot 132 and the first protrusion 131, so as to further improve the connection stability between the sheet metal 130 and the housing 110.

[0043] The overlapping arrangement of the ends of the sheet metal 130 and the shell 110 can improve the strength of the connection between the shell 110 and the core 120. To further improve the stability of the shell 110 and reduce the risk of separation of the shell 110 and the core 120, the shell 110 and the sheet metal 130 can be arranged in a stepped shape, with the sheet metal 130 abutting against the ends of the shell 110, and the shell 110 and the sheet metal 130 buckling, so as to reduce the risk of the shell 110 warping. Figure 5 as well as Figure 6 As shown, in some embodiments, the shell 110 has a third end 114 defining a second opening 113, the third end 114 has a first wall 1143 and a second wall 1144, the first wall 1143 defines a third slot 1145, the third slot 1145 is connected to the second opening 113, the second wall 1144 is arranged on the side of the third end 114 away from the first opening 112, the second wall 1144 intersects with the first wall 1143, the sheet metal part 130 has a fourth end 133 on the side close to the first opening 112, the fourth end 133 has a third wall 1331 and a fourth wall 1332, the third wall 1331 intersects with the fourth wall 1332, the fourth end 133 is passed through the third slot 1145, the third wall 1331 abuts against the first wall 1143, and the fourth wall 1332 abuts against the second wall 1144. When in use, external force is applied to the second end 122 or the sheet metal 130. Since the third wall 1331 abuts against the first wall 1143, the shell 110 will not be bent directly, and the risk of rupture of the shell 110 is reduced. In addition, the fourth wall 1332 abuts against the second wall 1144, and the sheet metal 130 can limit the bending, deformation and warping of the second end 122 of the shell 110, thereby further enhancing the connection stability between the sheet metal 130 and the shell 110, and further reducing the risk of rupture of the shell 110.

[0044] The shell 110 is sleeved on the outside of the core 120. The core 120 generally includes a PCBA (printed circuit board assembly), connecting wires and an injection molded support. The PCBA (printed circuit board assembly) is an electrical connection terminal 1211. The PCBA (printed circuit board assembly) is connected to the injection molded support to form a first end 121, and the connecting wire is connected to the injection molded component to form a second end 122. The setting of the injection molded support can improve the stability of the electrical connection of each part in the core 120 and improve the transmission stability of information and electric energy. Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As shown, in some embodiments, the core 120 includes a first injection molded part 123 and a second injection molded part 124, the first injection molded part 123 is disposed in the accommodating cavity 111 and attached to the electrical connection terminal 1211, the second injection molded part 124 is penetrated through the accommodating cavity 111 and sleeved on the first injection molded part 123, one end of the first injection molded part 123 away from the second opening 113 is exposed to the second injection molded part 124, along a direction perpendicular to the first direction, the shell 110 is connected to the first injection molded part 123 and the side of the second injection molded part 124 away from the electrical connection terminal 1211, and the sheet metal part 130 is sleeved on the side of the second injection molded part 124 away from the first injection molded part 123. Specifically, during the manufacturing process, the PCBA (printed circuit board assembly) inside the core 120 is first arranged and set, and then the first injection molded part 123 is injection-molded and connected to the PCBA (printed circuit board assembly), and the PCBA (printed circuit board assembly) is partially exposed from the first injection molded part 123, thereby forming a first end 121 that can be connected to the terminal. Since it is necessary to position and support each part of the PCBA (printed circuit board assembly) during injection molding, holes will be left on the first injection molded part 123 after the injection molding is completed. Therefore, the second injection molded part 124 is injection-molded again on the first injection molded part 123. On the one hand, the second injection molded part 124 can fill the holes on the first injection molded part 123, and on the other hand, the radial size of the second injection molded part 124 can be reasonably controlled to facilitate the design and installation of the housing 110. The housing 110 is connected to the portion of the first injection molded part 123 exposed to the second injection molded part 124, and the side of the second injection molded part 124 away from the first injection molded part 123, thereby avoiding the housing 110 from being connected to a single component on the core 120. The connection between the housing 110 and the core 120 is highly stable and not easy to loosen. It should be noted that the sheet metal part 130 is sleeved on the second injection molded part 124, and a spacing component may be provided between the sheet metal part 130 and the second injection molded part 124, which is not limited here.

[0045] In order to facilitate the connection between the first end 121 and the terminal device and reduce the interference between the components at the connection port of the plug 100 and the terminal device, the end of the housing 110 where the first opening 112 is provided may be provided with an escape area. Figure 6As shown, in some embodiments, the housing 110 has a third end 114 and a fifth end 115, the third end 114 defines a second opening 113, the fifth end 115 defines a first opening 112, and the fifth end 115 covers an end of the first injection molded part 123 away from the second opening 113. In a direction perpendicular to the first direction, the first outer diameter a of the fifth end 115 and the second outer diameter b of the third end 114 satisfy: a<b. Specifically, the fifth end 115 of the housing 110 can be integrally formed with the third end 114. According to different avoidance requirements, the first outer diameter a can be 0.6b, 0.7b or 0.85b, which is not limited here. The outer peripheral wall of the fifth end 115 can form an avoidance groove. Preferably, each wall surface of the fifth end 115 can adopt a rounded transition to improve the strength of the fifth end 115, optimize the stress distribution at the fifth end 115, reduce the stress concentration of the fifth end 115, and improve the convenience of processing the housing 110. Since the side of the first injection molded part 123 close to the second opening 113 is covered with the second injection molded part 124, and the side of the first injection molded part 123 close to the first opening 112 is not covered with the second injection molded part 124, the shell 110 can be directly connected to the first injection molded part 123 at one end of the first injection molded part 123 close to the first opening 112, and the first injection molded part 123 is arranged in the accommodating cavity 111 of the shell 110. This makes the shell 110 still have sufficient radial thickness when the first outer diameter a of the shell 110 is smaller than the second outer diameter b, so that the shell 110 still has sufficient strength at the first end 121 to protect the core 120, thereby reducing the risk of damage to the first injection molded part 123 and the PCBA (printed circuit board assembly).

[0046] The sheet metal part 130 is connected to the second end 122, and the second end 122 has a connecting wire 1221. In order to improve the connection stability between the connecting wire 1221 and the PCBA (printed circuit board assembly), the core 120 can be provided with a third injection molded part 125. Figure 2 , Figure 5 as well as Figure 6As shown, in some embodiments, the core 120 further has a third injection molded part 125, the third injection molded part 125 passes through the second opening 113 and is sleeved on the connecting wire 1221. In a direction perpendicular to the first direction, the end of the third injection molded part 125 close to the first opening 112 overlaps with the end of the second injection molded part 124 away from the first opening 112, and the sheet metal part 130 is sleeved on the side of the third injection molded part 125 away from the second injection molded part 124. The third injection molded part 125 extends out of the second opening 113, thereby greatly enhancing the strength of the second end 122 at the second opening 113, and the transmission stability of the connecting wire 1221 of the core 120 can be further improved. The overlapping arrangement of the end of the second injection molded part 124 and the end of the third injection molded part 125 can further improve the connection strength and connection stability between the second injection molded part 124 and the third injection molded part 125. The overlapping arrangement of the second injection molding 124 and the third injection molding 125 can be that the second injection molding 124 is provided with a slot, and the third injection molding 125 is inserted into the slot defined by the second injection molding 124, or the third injection molding 125 is provided with a slot, and the second injection molding 124 is inserted into the slot of the third injection molding 125, or the connecting ends of the second injection molding 124 and the third injection molding 125 are both configured as steps, and the two are abutted and buckled, so that the two can enhance the connection strength while also having a certain limiting effect on the movement in the first direction. For details, please refer to the connection between the sheet metal part 130 and the shell 110, which will not be repeated here. Since the connecting wire 1221 can be curled and bent, accordingly, the hardness of the third injection molding 125 can be less than the hardness of the shell 110, and the flexibility of the third injection molding 125 can be better than the flexibility of the shell 110.

[0047] In the processing of some embodiments, after PCBA (printed circuit board assembly) is assembled and injection molded to form the first injection molded part 123 and the second injection molded part 124, the housing 110 can be sleeved on the first injection molded part 123 and the second injection molded part 124, and the sheet metal part 130 is abutted against the end of the housing 110 with the second opening 113, the connecting wire 1221 passes through the second opening 113, and the mold of the third injection molded part 125 is sleeved on the connecting wire 1221, and then the injection molding material is injected into the second opening 113, so that the injection molding material fills the gap between the second injection molded part 124 and the housing 110 and the sheet metal part 130 from the second opening 113. The injection molding length outside the second opening 113 can be set according to the protection requirements of the connecting wire 1221. After the injection molding material solidifies, the third injection molded part 125 that is penetrated through the second opening 113 and connected to the second injection molded part 124 and the sheet metal part 130 can be obtained. The plug 100 can be obtained by removing the mold.

[0048] The injection length of the third injection molded part 125 from the second opening 113 to the first opening 112 along the first direction can be set according to the connection requirements of the second injection molded part 124, the shell 110 and the sheet metal part 130. The third injection molded part 125 can improve the strength of the plug 100, improve the connection stability between the various components of the plug 100, and reduce the risk of separation and damage of the shell 110, the sheet metal part 130 and the second injection molded part 124. Figure 3 As shown, in some embodiments, the third injection molded part 125 has a first end wall 1251 on a side close to the first opening 112, the sheet metal part 130 has a second end wall 134 on a side close to the first opening 112, and the first end wall 1251 is located on a side of the second end wall 134 close to the first opening 112. That is, the third injection molded part 125 extends from the second opening 113 to a side of the sheet metal part 130 and the housing 110 that are close to the first opening 112, and the first end wall 1251 is located on a side of the second end wall 134 that are close to the first opening 112, thereby avoiding the overlap of the boundary between the third injection molded part 125 and the second injection molded part 124 and the boundary between the sheet metal part 130 and the housing 110, greatly reducing the risk of the sheet metal part 130 and the housing 110 being separated and the risk of the third injection molded part 125 and the second injection molded part 124 being separated, thereby improving the connection stability of the various parts of the plug 100. In some embodiments, the third injection molded part 125 can space the sheet metal part 130 and the second injection molded part 124 to avoid direct contact between the sheet metal part 130 and the second injection molded part 124. The third injection molded part 125 has high wear resistance and good flexibility, and thus has good buffering and protective effects, reducing the wear of the sheet metal part 130 on the second injection molded part 124.

[0049] The sheet metal part 130 is connected to the third injection molded part 125. In order to improve the connection stability between the sheet metal part 130 and the third injection molded part 125 and reduce the risk of the sheet metal part 130 being dislocated due to the bending of the third injection molded part 125, the sheet metal part 130 can be clamped to the third injection molded part 125. Specifically, the sheet metal part 130 can have a protrusion for clamping and the third injection molded part 125 can have a corresponding groove, or the third injection molded part 125 can have a protrusion for clamping and the sheet metal part 130 can have a corresponding groove. Preferably, the protrusion and the groove can be arranged along the circumferential direction. Figure 3 as well as Figure 6As shown, in some embodiments, the third injection molded part 125 has a sixth end 1252 and a seventh end 1253, the sixth end 1252 is sleeved on the second injection molded part 124, the sheet metal part 130 is sleeved on the sixth end 1252, the seventh end 1253 is sleeved on the connecting wire 1221, and the outer peripheral wall of the sixth end 1252 close to the seventh end 1253 also has a third protrusion 1254, and the sheet metal part 130 is connected to the third protrusion 1254; wherein, the third protrusion 1254 has a third end wall 1255 on the side close to the first opening 112, and the third end wall 1255 intersects with the first direction, and the sheet metal part 130 has a fourth end wall 135 intersecting with the first direction, and the third end wall 1255 abuts against the fourth end wall 135. That is, the third injection molded part 125 is provided with a third protrusion 1254 , and the corresponding third protrusion 1254 is disposed in the slot of the sheet metal part 130 , so that the connection stability between the sheet metal part 130 and the third injection molded part 125 is further improved.

[0050] Since the third injection molded part 125 will be bent, the sheet metal part 130 is connected to the third injection molded part 125. If the end of the sheet metal part 130 directly contacts the bent area of ​​the third injection molded part 125, the stress concentration and wear of the bent area will be aggravated to a certain extent. Therefore, in order to reduce the stress concentration and wear of the bent area of ​​the third injection molded part 125, the connection between the sixth end 1252 and the seventh end 1253 can have different outer diameters, such as Figure 3 As shown, in some embodiments, the third protrusion 1254 has a fifth end wall 1256 on the side facing away from the first opening 112, and the fifth end wall 1256 intersects with the first direction, and the sheet metal part 130 has a sixth end 1252 surface on the end facing away from the first opening 112; the sixth end 1252 surface coincides with the fifth end 115 surface, or the sixth end 1252 surface is arranged on the side of the fifth end 115 surface close to the first opening 112. When in use, the third injection molded part 125 is bent at the connection between the sixth end 1252 and the seventh end 1253, and the sheet metal part 130 cannot rub against the peripheral wall of the seventh end 1253, thereby effectively reducing the wear of the third injection molded part 125 and extending the life of the plug 100.
