[0002] In industries relevant to industrial communication, a connector is used for data and power transmission between Internet of Things (IoT) devices. This connector must also exhibit a certain level of dust and water resistance. Relevant industries include, but are not limited to, the Ethernet and camera industries.

[0003] In the prior art, a pin-type connector is expensive. This is due to the fact that, firstly, the sealing between the components of the female and male sockets of the pin-type connector is usually achieved using sealing rings, requiring a large number of these rings and resulting in high costs; and secondly, the pin of the female and male sockets of the pin-type connector undergoes a machining process, meaning that the pin can only be gold-plated by barrel plating, which leads to high machining costs. The combination of these two factors results in high costs for both the sockets of the pin-type connector and the connector itself.

[0004] Therefore, the costs for the connector's sockets as well as for the connector itself must be reduced, based on the fact that the pin-type connector achieves the required level of dust and water resistance. Content of the invention

Detailed descriptions

[0032] To clarify the tasks, technical solutions, and advantages of the embodiments of the present application, the technical solutions in the embodiments of the present application are described below in detail, in conjunction with the accompanying drawings. Obviously, the described embodiments represent only a subset of the embodiments of the present application and do not include all embodiments. Based on the embodiments in the present application, all other embodiments that are attainable by a person skilled in the art without inventive step are intended to fall within the scope of protection of the present application. The following embodiments and features in the embodiments can be combined without conflict.

[0033] In the prior art, the female bushing is provided with annular recesses running around its circumference on the base body. Sealing rings are attached to these recesses, and the base body is then positioned on the bushing body, so that the gap between the base body and the bushing body is sealed by sealing rings. The same applies to the male bushing. The gap between the base body and the bushing body of the male bushing is sealed by sealing rings. This increases the number of sealing rings used and thus the cost of the bushings.In addition, a female pin for the female socket and a male pin for the male socket are machined, so that both female pins and male pins are completely gold-plated by barrel plating, resulting in a large gold-plated area and thus increasing the cost of the female socket and the male socket.

[0034] To overcome the disadvantages of the prior art, embodiments of the present application provide a female bushing and a male bushing. In the female bushing, the sealing connection between the first base body and the first bushing body is achieved by providing the first sealing structure on the outer wall surface of the first base body. In the male bushing, the sealing connection between the second base body and the second bushing body is achieved by providing the second sealing structure on the outer wall surface of the second base body. This reduces the number of sealing rings used for the female bushing and the male bushing, respectively, thus solving the problem of cost reduction. Furthermore, the female pin for the female bushing and the male pin for the male bushing can be applied selectively.By applying only the coupled part of the female or male pen, the applied area is reduced and costs are lowered.

[0035] The content of the present application is described in more detail below in conjunction with the attached figures, so that the person skilled in the art can recognize the content of the present application more clearly and in greater detail.

[0036] As in Fig. 1 and Fig. As shown in Figure 3, a female bushing 10 comprises a first bushing body 100, a first base body 110 and a first coupling element 120, wherein the first bushing body 100 has a receiving hole 101.

[0037] As in Fig. 1 and Fig. As shown in Figure 3, in some embodiments, a circumferential threaded structure is provided on an outer wall surface of the first bushing body 100. This threaded structure is used for connection to a nut with a corresponding internal thread. A sealing ring can be used to seal the gap between the nut and the first bushing body 100. If the female bushing 10 needs to be attached to a device or a panel of the device, the device or panel can have a bore, and the first bushing body 100, on which a sealing ring is already fitted, passes through the bore and is connected to the nut via the thread. The sealing ring then seals the gap between the device and the female bushing 10.

[0038] As in Fig. 1 and Fig. As shown in Figure 3, the female bushing 10 is designed such that an outer contour of the first base body 110 fits the receiving hole 101, with a first sealing structure 111 being provided on an outer wall surface of the first base body 110. By way of example, the first sealing structure 111 consists of several sealing protrusions arranged in a ring-like pattern around the circumference of the first base body 110. Furthermore, the first sealing structure 111 and the first base body 110 are formed as injection-molded, one-piece structures. The first base body 110 is positioned in the receiving hole 101. The first sealing structure 111 is sealedly connected to a wall of the receiving hole 101.

[0039] As in Fig. 1 and Fig. As shown in Figure 3, in some embodiments, the first sealing structure 111 on the outer wall surface of the first base body 110 comprises several sealing protrusions arranged in a ring-like pattern around the circumference of the first base body 110, thus achieving improved water and dust resistance between the first base body 110 and the first bushing body 100 of the female bushing 10. Furthermore, the first sealing structure 111 and the first base body 110 are designed as injection-molded, one-piece structures, which simplifies manufacturing by injection molding and allows the first sealing structure 111 itself to possess a certain degree of elasticity and deformation.

[0040] During manufacturing, the sealing ridges of the first sealing structure 111 are higher than the outer wall surface of the first base body 110. This creates a press-fit and sealing connection between the first sealing structure 111 and the bore wall of the receiving hole 101, resulting in improved sealing performance. Using the first sealing structure 111 instead of sealing rings simultaneously reduces the number of sealing rings required, thus lowering the cost of the female bushing 10.

[0041] As in Fig. 1 and Fig. As shown in Figure 3, the female socket 10 is provided with a through-hole 112 in the first base body 110 for the passage of the first coupling element 120. The first coupling element 120 passes through the through-hole 112 in the first base body 110 and is fixed relative to the first base body 110. The first coupling element 120 is configured to be electrically coupled to a second coupling element 220 on a male socket 20 that fits the female socket 10.

[0042] As in Fig. 1 and Fig. As shown in Figure 3, in some embodiments annular protrusions are provided on a redundancy area 123 of the first coupling element 120, so that the first coupling element 120 is press-fitted through the through hole 112 to the first base body 110 in order to prevent axial movement of the first coupling element 120 along the through hole 112.

[0043] The first coupling element 120 is a stamped coupling element produced using a stamping process. One end of the first coupling element 120 is a coupling end 121 with a contact hole, and the other end is a solid connecting end 127. Furthermore, both the inner and outer surfaces of the coupling end 121 are provided with an electrically conductive coating, while the connecting end 127 is not. The coupling end 121 is configured to be electrically coupled to the second coupling element 220 at the male socket 20, which fits the female socket 10.

[0044] In some embodiments, the electrically conductive coating of the first coupling element 120 is produced by gold plating. By means of stamping, the first coupling element 120 can be selectively gold-plated in mass production to control the gold plating of the inner and outer surfaces of the coupling end 121 of the first coupling element 120, while the connecting end 127 remains unplated. This reduces the gold-plated area and, consequently, the machining costs of the first coupling element 120 and, in turn, the costs of the female socket 10.

[0045] Furthermore, the first coupling element 120 is a rotary structure and has a diameter of 0.6 mm to 1 mm.

[0046] In some embodiments, the coupling end 121 of the first coupling element 120 is formed by roll bending using a stamping process in order to produce the first coupling element 120 with dimensions from 0.6 mm to 1 mm, such as 0.6 mm, 0.7 mm, 0.8 mm and 1 mm, etc. This controls the distance between the through holes 112 of two adjacent first coupling elements 120 of the first base body 110 such that the distance between two adjacent through holes 112 maintains a suitable thickness to avoid the influence of an excessively thin thickness on the fastening of the first coupling element 120 to the first base body 110.

[0047] The coupling end 121 of the first coupling element 120 is provided with a contact hole. The axial direction of the contact hole is the same as the extension direction of the first coupling element 120. In the axial direction of the contact hole, the contact hole comprises a contact area 122 and a redundancy area 123, which are connected sequentially, with the redundancy area 123 being located on a side close to the connection end 127.

[0048] As in Fig. 1 and Fig. As shown in Figure 5, in some embodiments the redundancy area 123 is located at the other end of the contact area 122 as the end for the coupling connection with the second coupling element 220 of the male socket 20. This provides redundant space for the coupled depth of the second coupling element 220 of the male socket 20, so that not only is the coupled area of ​​the first coupling element 120 with the second coupling element 220 increased, but tolerance for mounting the second coupling element 220 in the second base body 210 can also be provided.

[0049] An insulating structure 124 is arranged between the contact area 122 and the redundancy area 123, and the insulating structure 124 is used for sealing the contact area 122 from the redundancy area 123.

[0050] As in Fig. 3 and Fig. As shown in Figure 5, in some embodiments, the first bushing body 100 has a hollow chamber at its rear end, i.e., in the direction of the connecting end 127 of the first coupling element 120. The hollow chamber is filled by an adhesive casting process, and the rear end of the female bushing 10 is completely sealed, thus enabling the female bushing 10 to achieve improved dust and water resistance.An insulating structure 124 is thus arranged between the contact area 122 and the redundancy area 123 in order to prevent the adhesive from flowing through the gap between the first coupling element 120 and the first base body 110 and through a central bore formed by roll bending the coupling end 121 of the first coupling element 120 to the contact area 122 of the first coupling element 120 during the adhesive casting process, and thus affecting the electrical coupling property of the second coupling element 220 of the male socket 20.

[0051] The insulating structure 124 comprises at least two insulating plates 125, wherein the at least two insulating plates 125 are arranged spaced apart from each other in the axial direction of the contact hole between the contact area 122 and the redundancy area 123.

[0052] As in Fig. As shown in Figure 3, in some embodiments the insulating structure 124 comprises at least two insulating plates 125. This is to prevent a gap between the individual insulating plates 125 and the first coupling element 120 caused by machining defects. The at least two insulating plates 125 can serve such a function that one is used for operation and the other acts as a backup. This completely isolates the adhesive outside the contact area 122 during the adhesive casting process, thus completely preventing the influence of the adhesive flow to the contact area 122 on the electrical coupling with the second coupling element 220 of the male socket 20.

[0053] Between the coupling end 121 and the connecting end 127 of the first coupling element 120 there is a bypass recess 126.

[0054] As in Fig. 3 and Fig. As shown in Figure 5, in some embodiments the first coupling element 120 can be machined by profile punching. This means that the coupling end 121 and the connecting end 127 of the first coupling element 120 can be machined from materials of different thicknesses. The clearance recess 126 is arranged between the coupling end 121 and the connecting end 127 to prevent the materials for the coupling end 121 and the connecting end 127 from interfering with each other during the punching process.

[0055] A first positioning structure 1271 is provided on an outer wall surface of the connection end 127 of the first coupling element 120, wherein the first positioning structure 1271 is used for mutual positioning with a second positioning structure on a printed circuit board in order to position the connection end 127 and the printed circuit board. The first positioning structure 1271 is, by way of example, a positioning stage.

[0056] As in Fig. 3 and Fig. As shown in Figure 5, in some embodiments the first positioning structure 1271 is arranged at the connection end 127 and the second positioning structure is located on the printed circuit board. The second positioning structure can be a circular hole, a square hole, or the like, formed in the printed circuit board, which fits the connection end 127 and its positioning stage of the first coupling element 120 in order to insert the connection end 127 of the first coupling element 120 into a hole formed in the circuit, so that the first positioning structure 1271 rests against the edge of the hole in the printed circuit board and clamps the first coupling element 120, thus preventing the first coupling element 120 from being inserted further and thus positioning the first positioning structure 1271 and the printed circuit board relative to each other.

[0057] As in Fig. 3 and Fig. As shown in Figure 5, in some embodiments the first positioning structure 1271 is a positioning step, wherein the positioning step rests on the edge of the bore in the printed circuit board, so that the first coupling element 120 is clamped and thus the mutual positioning of the first coupling element 120 and the printed circuit board is achieved.

[0058] Furthermore, the coupling end 121 of the first coupling element 120 is a twisted structure, and the connecting end 127 is a plate-shaped structure. Alternatively, both the coupling end 121 and the connecting end 127 are twisted structures.

[0059] In some embodiments, the female socket 10 is connected to another component or device via the connecting end 127 of the first coupling element 120. For example, the female socket is soldered to a printed circuit board. Both the coupling end 121 and the connecting end 127 of the first coupling element 120 can be rotary structures. The female socket can also be soldered to a wire. The coupling end 121 of the first coupling element 120 can be a rotary structure. The connecting end 127 can be either a flat structure or a rotary structure.

[0060] The end part of the connecting end 127 of the first coupling element 120 is provided with at least one of a recess and a bending structure, wherein at least one of a contour surface of the recess and a contour surface of the bending structure is formed as the solder cup structure 1272.

[0061] As in Fig. As shown in Figure 6, in some embodiments the coupling end 121 of the first coupling element 120 is a rotary structure and the connecting end 127 is a plate-shaped structure. The end part of the connecting end 127 of the first coupling element 120 is provided with a solder cup structure 1272 formed by a bending structure. The solder cup structure 1272 is designed for soldering to a conductor. The solder cup structure increases the contact area between the connecting end 127 of the first coupling element 120 and the conductor, thus increasing the reliability of the soldering.

[0062] In some other embodiments, the coupling end 121 and the connecting end 127 of the first coupling element 120 are both turned structures. Thus, the connecting end 127 is designed with an arc-shaped recess to form the solder cup structure 1272 and thereby increase the contact area between the connecting end 127 of the first coupling element 120 and the conductor.

[0063] To prevent the rotation of the first coupling element 120 in the first base body 110, a through-hole 112 is provided in the first base body 110 for the passage of the first coupling element 120. A first limiting structure 1121 is provided on one wall of the through-hole 112, and a second limiting structure 1273 is provided on the outer wall surface of the first coupling element 120. When the first coupling element 120 is arranged continuously in the through-hole 112, the first limiting structure 1121 fits the second limiting structure 1273 to restrict the rotation of the first coupling element 120 about its own axis. The first limiting structure 1121 consists of a limiting depression and a limiting protrusion, and the second limiting structure 1273 consists of the other limiting depression and the limiting protrusion.

[0064] As in Fig. As shown in Figure 9, in some embodiments the connecting end 127 of the first coupling element 120 is a plate-shaped structure. A first limiting structure 1121, i.e., two axial limiting grooves, is provided in the inner wall surface of the through-hole 112 of the first base body 110, and a second limiting structure 1273, i.e., two limiting protrusions, is provided at the connecting end 127 of the first coupling element 120. The two axial grooves and the two protrusions align with each other to limit the rotation of the first coupling element 120 in the through-hole 112 of the first base body 110. Furthermore, the opening direction of the solder cup structure 1272 can be limited so that it is oriented towards the outer wall surface of the female socket 10.

[0065] In some other embodiments, the first limiting structure 1121 may be a limiting projection and the second limiting structure 1273 may be a limiting groove that fits the limiting projection in order to limit the rotation of the first coupling element 120 in the through-hole 112 of the first base body 110 and to control the alignment of the solder cup structure 1272.

[0066] In some embodiments, the connecting end 127 of the first coupling element 120 of the female socket 10 is provided to be a bent structure, wherein the bending angle is in the range of 90° to 180°, such as 90°, 120°, 150° or similar, so that the female socket 10 and the male socket 20 have several possibilities for their plug connection directions and thus broader application scenarios.

[0067] As in Fig. 2 and Fig. As shown in Figure 4, the male socket 20 comprises a second socket body 200, a second base body 210 and a second coupling element 220, wherein the second socket body 200 has a receiving chamber 201.

[0068] As in Fig. 2 and Fig. As shown in Figure 4, in some embodiments, a circumferential threaded structure is provided on an outer wall surface of the second bushing body 200. This threaded structure is used for connection to a nut with a corresponding internal thread. A sealing ring can be used to seal the connection between the nut and the second bushing body 200. If the male bushing 20 needs to be attached to a device or a panel of the device, the device or panel can have a bore, and the second bushing body 200, which already has a sealing ring fitted to it, passes through the bore and is connected to the nut via the thread. The sealing ring then seals the gap between the device and the male bushing 20.

[0069] As in Fig. 2 and Fig. As shown in Figure 4, the male bushing 20 is designed such that an outer contour of the second base body 210 fits the receiving chamber 201, with a second sealing structure 211 being provided on an outer wall surface of the second base body 210. By way of example, the second sealing structure 211 consists of several sealing projections arranged in a ring-like pattern around the circumference of the second base body 210. The second sealing structure 211 and the second base body 210 are designed as a single-piece structure. The second base body 210 is arranged in the receiving chamber 201. The second sealing structure 211 is sealed to a chamber wall of the receiving chamber 201.

[0070] As in Fig. 2 and Fig. As shown in Figure 4, in some embodiments, the second sealing structure 211 on the outer wall surface of the second base body 210 comprises several sealing projections arranged annularly around the circumference of the second base body 210, thus achieving improved water and dust resistance between the second base body 210 and the second bushing body 200 of the male bushing 20. Furthermore, the second sealing structure 211 and the second base body 210 are formed as injection-molded, one-piece structures, which simplifies manufacturing by injection molding and allows the second sealing structure 211 to possess a degree of elasticity and deformation. During manufacturing, the sealing projections of the second sealing structure 211 are higher than the outer wall surface of the second base body 210.This creates a press-fit and sealing connection between the second sealing structure 211 and the bore wall of the receiving chamber 201, thus achieving a better sealing effect. By using the second sealing structure 211 instead of sealing rings, the number of sealing rings used is simultaneously reduced, thereby lowering the cost of the male bushing 20.

[0071] As in Fig. 2 and Fig. As shown in Figure 4, the second coupling element 220 is arranged in the extension direction of the receiving chamber 201. The second coupling element 220 passes through the second base body 210 and is fixed relative to the second base body 210. The second coupling element 220 is configured to be electrically coupled to the first coupling element 120 at the female socket 10, which fits the male socket 20. The second coupling element 220 and the second base body 210 are formed as a single-piece structure.

[0072] In some embodiments, the second coupling element 220 is provided with annular protrusions to prevent axial movement of the second coupling element 220 in the second base body 210. As in Fig. 4 and Fig. As shown in Figure 7, an embossing structure can also be provided on the second coupling element 220 to prevent rotation of the second coupling element 220 in the second base body 210.

[0073] As in Fig. As shown in Figure 2, in some embodiments the products of the second coupling element 220 and the second base body 210 are formed as a one-piece structure by means of insert injection molding, so that steps for assembling the second coupling element 220 to the second base body 210 are reduced, the assembly processes are reduced and time costs are saved.

[0074] One end of the second coupling element 220 is an electrically conductive coupling end 221, and the other end is a fastening end 222, wherein one surface of the electrically conductive coupling end 221 is provided with an electrically conductive coating, and one surface of the fastening end 222 is not provided with an electrically conductive coating. The electrically conductive coupling end 221 is configured to be plugged into and electrically coupled to the coupling end 121 of the first coupling element 120 at the female socket 10, which fits the male socket 20.

[0075] In some embodiments, the second coupling element 220 can be manufactured either by stamping or by machining. By means of insert injection molding, the products of the second coupling element 220 and the second base body 210 are then formed as a single-piece structure. The embossed structure of the second coupling element 220 can also be machined. Furthermore, the second coupling element 220 produced by machining can also be applied in sections.

[0076] In some embodiments, the electrically conductive coating of the second coupling element 220 is produced by gold plating. The second coupling element 220 can be selectively gold-plated in mass production to control the coating of the inner and outer surfaces of the electrically conductive coupling end 221 of the second coupling element 220, while the mounting end 222 remains unplated. This reduces the gold-plated area and thus the machining costs of the second coupling element 220, and consequently the costs of the male socket 20.

[0077] In some other embodiments, the second base body 210 and the second coupling element 220 of the male socket 20 are designed as separate components, and the products do not form a one-piece structure. As in Fig. As shown in Figure 8, the electrically conductive coupling end 221 of the second coupling element 220 is a rotary structure, and the fastening end 222 is a plate-shaped structure. As shown in Fig. As shown in Figure 7, the electrically conductive coupling end 221 of the second coupling element 220 is alternatively a rotary structure and the fastening end 222 is also a rotary structure.

[0078] In some embodiments, the electrically conductive coupling end 221 of the second coupling element 220 is a turned structure. The electrically conductive coupling end 221 of the second coupling element 220 is formed by roll bending using a stamping process to enable the production of the second coupling element 220 with dimensions ranging from 0.6 mm to 1 mm, such as 0.6 mm, 0.7 mm, 0.8 mm, and 1 mm, etc. This controls the distance between two adjacent second coupling elements 220 of the second base body 210 in such a way as to avoid any influence on the fastening of the second coupling element 220 to the second base body 210.

[0079] In some embodiments, the second sealing structure 211 and the second base body 210 are not designed as injection-molded one-piece structures. As in Fig. As shown in Figure 8, the second bushing body 200 has a hollow chamber inside at a rear end of the second base body 210, i.e., in the direction of the fastening end 222 of the second coupling element 220. The hollow chamber is filled by an adhesive casting process, and the rear end of the male bushing 20 is completely sealed, so that the male bushing 20 can achieve better dust and water resistance.An insulating structure is thus arranged at the electrically conductive coupling end 221 to prevent the adhesive from flowing through the gap between the second coupling element 220 and the second base body 210, as well as through a central bore formed by roll bending the electrically conductive coupling end 221 of the second coupling element 220, to the electrically conductive coupling end 221 of the second coupling element 220 during the adhesive casting process. This would prevent the adhesive from affecting the electrical coupling properties of the first coupling element 120 of the female socket 10. The insulating structure comprises at least two insulating plates. These at least two insulating plates are spaced apart from each other at the electrically conductive coupling end 221 in the axial direction of the contact hole.The reason for providing at least two insulating plates is to prevent a gap between the individual insulating plates and the second coupling element 220 caused by machining errors. The at least two insulating plates can function such that one serves for operation and the other as a backup. This ensures that the adhesive is completely isolated outside the electrically conductive coupling end 221 during the adhesive casting process, thus completely preventing the influence of the adhesive flow to the electrically conductive coupling end 221 on the electrical coupling with the first coupling element 120 of the female socket 10.

[0080] A first positioning part 2221 is provided on an outer wall surface of the fastening end 222 of the second coupling element 220, wherein the first positioning part 2221 is used for mutual positioning with a second positioning part on a printed circuit board in order to position the fastening end 222 and the corresponding printed circuit board.

[0081] As in Fig. 4 and Fig. As shown in Figure 7, in some embodiments the first positioning part 2221 is arranged at the mounting end 222 and may be a positioning step, and the second positioning part is located on the circuit board and may be a circular hole, a square hole or the like formed in the circuit board, which fits the mounting end 222 and its positioning step of the second coupling element 220 in order to insert the mounting end 222 of the second coupling element 220 into a hole formed in the circuit, so that the positioning step of the first positioning part 2221 rests against the edge of the hole in the circuit board and clamps the second coupling element 220, thus preventing the second coupling element 220 from being inserted further and thus positioning the first positioning part 2221 and the circuit board relative to each other.

[0082] In some embodiments, the end part of the fastening end 222 of the second coupling element 220 is provided with at least one recess and a bending structure, wherein at least one contour surface of the recess and one contour surface of the bending structure is designed as the solder cup structure. As in Fig. As shown in Figure 8, the solder cup structure is configured for soldering with a conductor. The solder cup structure increases the contact area between the mounting end 222 of the second coupling element 220 and the conductor, thus increasing the reliability of the soldering.

[0083] In some other embodiments, the electrically conductive coupling end 221 and the fastening end 222 of the second coupling element 220 are both rotary structures. Thus, the fastening end 222 is designed with an arc-shaped recess to form the solder cup structure and thereby increase the contact area between the fastening end 222 of the second coupling element 220 and the conductor.

[0084] In some embodiments, the second sealing structure 211 and the second base body 210 are not designed as injection-molded, one-piece structures. To prevent rotation of the second coupling element 220 within the second base body 210, a first limiting structure 1121 is provided at the through-hole of the second base body 210, and a second limiting structure 1273 is provided on the outer wall surface of the second coupling element 220. When the second coupling element 220 is arranged continuously within the through-hole, the first limiting structure 1121 aligns with the second limiting structure 1273 to restrict the rotation of the second coupling element 220 about its own axis. The first limiting structure 1121 consists of a limiting depression and a limiting protrusion, and the second limiting structure 1273 consists of the other limiting depression and the limiting protrusion.

[0085] In some embodiments, the fastening end 222 of the second coupling element 220 of the male socket 20 is provided to be a bent structure, wherein the bending angle is in the range of 90° to 180°, such as 90°, 120° and 150°, so that the male socket 20 and the female socket 10 have several possibilities for their plug connection directions and thus broader application scenarios.

[0086] An embodiment of the present application further provides a connector. The connector comprises a female socket 10 and a male socket 20, wherein the female socket 10 and the male socket 20 are mated to each other.

[0087] As in Fig.As shown in Figure 3, in some embodiments the inner wall surface of an end of the first socket body 100 of the female socket 10 that is in contact with the male socket 20 can be provided with a threaded structure that fits the thread on the outer wall surface of the second socket body 200 of the male socket 20. When the female socket 10 and the male socket 20 are in a plug-in connection, a threaded connection exists between the first socket body 100 and the second socket body 200, and thus the first coupling element 120 and the second coupling element 220 are coupled to each other to achieve current supply.
