Description

receptacle connector

[0001] The present invention relates to a receptacle connector, and more particularly, to a receptacle connector connected to a plug connector and having improved thinness and EMC (Electro Magnetic Compatibility) performance.

[0002] Portable electronic devices such as cell phones, laptops, PMPs, portable game consoles, MP3 players, and smartphones, which have recently become widespread, are gradually expanding in type and function.

[0003] In particular, portable electronic devices are equipped with connector devices for data communication. These connector devices are composed of a receptacle connector mounted on a printed circuit board (PCB) within the portable electronic device and a plug connector that is connected to the receptacle connector, and are used to communicate data with external devices or supply power by connecting to a power supply.

[0004] Meanwhile, the receptacle connector and plug connector are equipped with individual contacts that are mounted on a board and are connected to form an electrical contact. Through these contacts, an electrical signal flows, enabling data transmission and reception and power supply.

[0005] Meanwhile, the next-generation USB interface standard, which improves data transfer speeds by more than 10 times compared to the past, has been completed, and portable electronic devices that can support it are being released one after another.

[0006] This has resulted in high-speed signaling at unprecedented speeds. This high-speed signaling inevitably leads to increased noise that can cause interference, and electrical signals flowing through contacts arranged adjacently within a confined space inevitably affect other components.

[0007] Meanwhile, the ability to block the influence of electrical signals from other elements while preventing the electrical signals flowing through the contacts from affecting other elements is called EMC (Electro Magnetic Compatibility) performance.

[0008] To improve this EMC performance, conventional receptacle connectors have a structure including a shell, a mid-plate, and a cover.

[0009] However, as high-speed signaling is achieved at a speed incomparable to that of the past, higher EMC performance than before is required, and development of connectors to satisfy this is required.

[0010] And, as electronic devices such as mobile phones are required to have a fully waterproof function that is more enhanced than the waterproof function of everyday life, receptacle connectors with enhanced waterproof function, including waterproofing materials, are being disclosed.

[0011] Accordingly, there is a need to develop a receptacle connector that is easy to assemble, has a waterproof function, and can further improve EMC performance.

[0012] Additionally, electronic devices such as smartphones are becoming increasingly smaller and slimmer to meet the needs of current customers.

[0013] Accordingly, connector devices applied to these electronic devices are also required to be smaller and thinner than before.

[0014] The present invention is intended to solve the above problems, and an object of the present invention is to provide a receptacle connector that is easy to assemble, has a waterproof function, and can further improve EMC performance.

[0015] Additionally, it aims to provide a thinner receptacle connector.

[0016] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0017] According to one aspect of the present invention, a receptacle connector is provided.

[0018] A receptacle connector (1) may include: an insulating portion (10); a contact portion (20) that electrically connects a plug connector and a substrate, and includes a plurality of first contacts (20a) arranged on an upper surface of the insulating portion (10) and a plurality of second contacts (20b) arranged on a lower surface of the insulating portion (10); an EMC pad (100) that is coupled to surround the outer side of the insulating portion (10) and electromagnetically shields the contact portion (20); and a cover (40) that is coupled to surround the outer side of the EMC pad (100).

[0019] At this time, the EMC pad (100) may include a contact portion (110) including an upper contact portion (110a) disposed on the upper surface of the insulating portion (10) and a lower contact portion (110b) disposed on the lower surface of the insulating portion (10); a body portion (120) seamlessly connecting one end of the upper contact portion (110a) and the lower contact portion (110b); and a potting portion (130) extending from the body portion (120) in the opposite direction to the contact portion (110) to surround the outer circumferential surface of the insulating portion (10) and form a potting area (S2) therein.

[0020] According to the above configuration, the receptacle connector according to the present invention has the effect of increasing the electromagnetic shielding performance of the contact portion by including an EMC PAD and further improving the EMC performance.

[0021] In addition, the receptacle connector has the effect of reducing thickness and making it thinner by having an EMC pad, excluding the shell that wraps around the outside of the insulation.

[0022] In addition, the EMC pad has a structure in which the upper contact portion and the lower contact portion are integrally connected without a break by the body portion, so it can be assembled to the insulating portion in a single process of joining them in the longitudinal direction of the insulating portion, which has the effect of making assembly easy.

[0023] In addition, the EMC pad has the effect of enhancing waterproof performance by forming a potting area through a potting section and eliminating micro-cracks through a waterproof material filled in the potting area and implementing a waterproof function.

[0024] In addition, the EMC pad has the effect of increasing waterproof performance by including a sealing member provided on the outer surface of the body part to increase watertightness between the plug connector and the EMC pad.

[0025] In addition, the EMC pad has the effect of preventing electromagnetic interference such as short circuits by forming a gap between the contact portion and the escape groove formed in the upper contact portion and the lower contact portion.

[0026] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

Furthermore, the term "connected" to another component includes, unless otherwise specified, the cases where the components are indirectly connected as well as the cases where the components are directly connected.

[0045] The terms "X-axis", "Y-axis", and "Z-axis" used in the description will be understood with reference to the coordinate system illustrated in the drawings. In addition, although the X-axis direction is referred to as the first direction, the Y-axis direction as the second direction, and the Z-axis direction as the third direction in the description, this is only an example according to a relative viewpoint, and the first to third directions and the coordinate axes (X, Y, Z axes) are only introduced to explain the relative positions between components, and do not limit the absolute positions of each component.

[0046] In addition, in explaining the present invention, specific descriptions of related known functions or configurations will be omitted in order to avoid obscuring the gist of the present invention.

[0047] Meanwhile, the names of plug connector and receptacle connector are only names used for the purpose of explaining the present invention, and it is obvious that a plug connector in a city may be referred to as a receptacle connector and a receptacle connector may be referred to as a plug connector.

[0048]

[0049] Hereinafter, a receptacle connector (1) according to one embodiment of the present invention will be described with reference to the drawings.

[0050] A receptacle connector (1) according to one embodiment of the present invention may be coupled to a substrate (not shown) such as a printed circuit board (PCB) provided in various electronic devices for connection with a plug connector (not shown).

[0051] In addition, the receptacle connector (1) of the present invention may be a connector that satisfies the USB Type-C (Universal Serial Bus Type C) standard.

[0052] A receptacle connector (1) according to one embodiment of the present invention can be utilized to supply data communication or power together with a plug connector (not shown).

[0053] A receptacle connector (1) and a plug connector (not shown) are formed by connecting a plurality of contacts mounted on a circuit board to form an electrical contact point, and when an electrical signal flows through these contacts, data transmission and reception are possible and power supply is possible. To this end, it goes without saying that some of the plurality of contacts may function as power terminals, and others may function as signal terminals.

[0054] Meanwhile, the receptacle connector (1) according to one embodiment of the present invention has the greatest feature of further including an EMC PAD (100) so as to implement high EMC performance (shielding performance) as high-speed signaling is performed.

[0055] In addition, a receptacle connector (1) according to one embodiment of the present invention is characterized in that it is configured to reduce thickness and make it thinner.

[0056] These EMC pads (100) can play a role in blocking and shielding noise that may cause interference.

[0057] A receptacle connector (1) according to one embodiment of the present invention can be configured to include the EMC pad (100) described above. In this case, the EMC pad (100) is formed seamlessly using a drawing method and is formed so that it can be easily assembled to the insulating portion (10).

[0058]

[0059] Referring to FIGS. 1 to 13, the receptacle connector (1) including the EMC pad (100) will be examined in more detail as follows.

[0060] As illustrated, a receptacle connector (1) according to one embodiment of the present invention may largely include an insulator (10), a contact (20), a cover (40), and a mid-plate (50). In addition, a waterproofing member (70) and a sealing member (60) for waterproofing may be included. In addition, an EMC pad (100) for shielding and EMC performance enhancement may be further included.

[0061] First, the insulating member (10) may have a width in the first direction, a length in the second direction, and a thickness in the third direction that are already set, and may have a plate shape in which the width and length are greater than the thickness.

[0062] This insulating portion (10) can be formed by injecting an insulating material, for example, a plastic resin, using an insert molding method, and can be formed integrally by insert molding together with the components constituting the receptacle connector (1). In one embodiment of the present invention, the insulating portion (10) is formed by insert molding, including the contact portion (20) and the midplate (50).

[0063] Meanwhile, the insulating part (10) may include a first insulating part (10a) and a second insulating part (10b).

[0064] The first insulating portion (10a) is a portion that provides a region in which contact portions (20) are arranged for electrical connection with an inserted plug connector, and can be broadly divided into a contact block (11) in which contact portions (20) are arranged and a stopper block (12) that limits the insertion distance of the plug connector.

[0065] The contact block (11) is a part in which contact portions (20) are arranged with a set pitch to form a contact point with the plug connector to be inserted, and when the plug connector and the receptacle connector (1) are coupled, the contact portions (20) can be formed to be exposed to the outside for contact.

[0066] Meanwhile, the stopper block (12) is connected to the contact block (11) in the second direction and is an extended portion, and has a size and shape that can come into contact with the inner surface of the potting portion (130) of the EMC pad (100) to be described later.

[0067] In other words, the stopper block (12) may have a shape that protrudes to the rear of the second direction of the contact block (11), and may have a width in the first direction of the setting, a length in the second direction, and a thickness in the third direction.

[0068] Compared to the contact block (11), this stopper block (12) has a shorter overall length (r1, Fig. 7a) and a larger overall width and thickness (see Fig. 2).

[0069] Accordingly, when the plug connector is inserted, the plug connector may form a contact with the contact block (11) and may be blocked by the longitudinal (second direction) front of the stopper block (12), thereby preventing further insertion. In other words, the stopper block (12) may limit the insertion distance so that the plug connector is not inserted beyond the contact block (11).

[0070] These contact blocks (11) and stopper blocks (12) are formed as one piece during molding and can form the first insulating portion (10a).

[0071] Meanwhile, the stopper block (12) can further form a joining hole (13) on both sides in the first direction so that the joining wing (43) of the upper cover (40a) can penetrate and join when the upper cover (40a) and the lower cover (40b) of the cover (40) are joined.

[0072] Through this, the cover (40) can be stably connected to the EMC pad (100) and the insulation (10) while wrapping around the EMC pad (100) including the insulation (10). In addition, the coupling wing (43) of the cover (40) can penetrate the stopper block (12) and the protruding portion can be mounted on the substrate and grounded.

[0073] By combining these covers (40), the EMC pad (100) can be more stably combined with the insulating part (10) and the bonding strength can be increased.

[0074] Meanwhile, the second insulating portion (10b) is connected to the stopper block (12) and can provide an exposed area so that the contact portion (20) can be mounted on the substrate and connected.

[0075] The receptacle connector (1) can be installed on the substrate as described above, and can transmit an electrical signal or power received from the plug connector to the substrate, or transmit an electrical signal or power received from the substrate through the plug connector. To this end, the receptacle connector (1) needs to be connected to the substrate, and at this time, it can be connected to the substrate through the second insulating portion (10b).

[0076] Meanwhile, as will be described later, the contact portion (20) may be exposed to the outside in the space between the stopper block (12) of the first insulating portion (10a) and the second insulating portion (10b). In this way, the space between the contact portions (20) where they are exposed may be filled with a waterproofing member (70) through a potting process as shown in FIGS. 7(a)(b) to prevent water from penetrating. The shape of the waterproofing member (70) may be determined according to the shape of the potting area (S2) of the potting portion (130) of the EMC pad (100).

[0077] Next, the contact portion (20) electrically connects the plug connector and the substrate, and may include a plurality of first contacts (20a) arranged on the upper surface of the third direction of the insulating portion (10), and a plurality of second contacts (20b) arranged on the lower surface of the third direction of the insulating portion (10).

[0078] In other words, the contact portion (20) can electrically connect the plug connector and the substrate by being connected to the plug connector inserted into the interior of the electronic device while the receptacle connector (1) is mounted on the substrate. Preferably, the contact portion (20) can be formed of a conductive material.

[0079] A plurality of first contacts (20a) and a plurality of second contacts (20b) constituting the contact portion (20) can be arranged at a predetermined pitch, and when the contact portion (10) described above is insert-molded, the plurality of contacts (20a, 20b) can be prevented from physical contact by the insulating material of the insulating portion (10). Preferably, the contact portion (20) can be arranged at a pitch that satisfies the pin specifications of USB type-C.

[0080] This contact portion (20) can be electrically connected by making contact with the plug contact portion (not shown) of the plug connector (not shown) that is inserted into the receptacle connector (1), and through this, the contact portion (20) can transmit and receive data and supply power while allowing an electric signal to flow.

[0081] Meanwhile, it is obvious that some of the first contact (20a) and second contact (20b) constituting the contact portion (20) can serve as power terminals, and others can serve as signal terminals.

[0082] In addition, the EMC pad (100) is combined to surround a portion of the outer side of the insulating portion (10) described above, and can perform the role of electromagnetically shielding the contact portion (20) while protecting the insulating portion (10).

[0083] These EMC pads (100) can be formed of a metal material and can be formed integrally without any seams.

[0084] Meanwhile, the EMC pad (100) forms a potting zone (S2) inside the second direction rearward, and this potting zone (S2) is a zone formed rearward in the second direction with the stopper block (12) of the first insulating portion (10a) as a partition wall, and can be formed between the stopper block (12) and the second insulating portion (10b). A potting liquid such as silicone can be applied to this potting zone (S2) to form a waterproof member (70) that completely surrounds the exposed contact portion (20).

[0085] This EMC pad (100) includes a contact portion (110), a body portion (120), and a potting portion (130), and a specific embodiment thereof will be described in more detail later.

[0086] Meanwhile, the EMC pad (100) may include a sealing member (60) along the outer circumferential surface on the front side in the second direction.

[0087] The sealing member (60) can seal the space between the plug connector inserted into the receptacle connector (1) and the EMC pad (100). That is, when the plug connector is inserted, the sealing member (60) is compressed by the plug connector and can perform a waterproof function to prevent water from penetrating.

[0088] This sealing member (60) can be formed to surround the outer surface of the body portion (120) of the EMC pad (100), specifically, the cylindrical first body (120a) having a length (b1) set in the second direction.

[0089] Meanwhile, the cover (40) has a structure that wraps around the outer side of the rear portion of the second direction of the EMC pad (100) described above and is coupled to the EMC pad (100) and the insulating portion (10).

[0090] This cover (40) is intended to protect the EMC pad (100) and the insulation (10), and may have a shape that can cover and wrap the outer surface of the rear side of the EMC pad (100). At this time, the EMC pad (100) is positioned on the inner side of the cover (40) and is combined with the cover (40).

[0091] Additionally, the cover (40) can be mounted on the substrate and fixedly joined.

[0092] Additionally, the cover (40) can be partially welded to the EMC pad (100) and grounded.

[0093] Specifically, referring to FIGS. 1 and 2, the cover (40) may include an upper cover (40a) and a lower cover (40b).

[0094] The upper cover (40a) can protect the potting portion (130) and the second insulating portion (10b) of the EMC pad (100) by covering the upper surface in the third direction of the EMC pad (100), and the lower cover (40b) can protect the potting portion (130) of the EMC pad (100) by covering the lower surface in the third direction.

[0095] Meanwhile, the upper surface of the EMC pad (100) means a surface opposite to the surface on which the receptacle connector (1) according to one embodiment of the present invention is coupled to the substrate, and the lower surface of the EMC pad (100) may mean the other surface on which the receptacle connector (1) is coupled to the substrate, but is not limited thereto.

[0096] The upper cover (40a) has fastening holes (41) formed on both sides for strong bonding with a substrate or electronic device, and can be fixedly bonded using a bonding member such as a bolt. In addition, it can further include a bonding wing (43) extending downward on both sides for bonding with the lower cover (40b), and the lower cover (40b) can form a bonding hole (44) so ​​that the bonding wing (43) can be fastened and inserted.

[0097] Accordingly, the upper cover (40a) and the lower cover (40b) can be joined together to wrap around the EMC pad (100) as one piece.

[0098] Next, the midplate (50) is placed on the insulating portion (10) and can perform a shielding function for the contact portion (20) while reinforcing the strength of the insulating portion (10).

[0099] The midplate (50) may be a bar shape having a length corresponding to the first contact (20a) and the second contact (20b) constituting the contact portion (20), and may connect the first insulating portion (10a) and the second insulating portion (10b).

[0100] Meanwhile, referring to FIG. 2, the midplate (50) is illustrated as two bar shapes separated into a first midplate (50a) and a second midplate (50b), but it is not limited thereto and may be a single plate shape formed integrally or a plurality of bar shapes.

[0101] However, the midplate (50) may be made of a material having greater strength than the insulating portion (10), for example, a metal material, and may be placed between the first insulating portion (10a) and the second insulating portion (10b) to reinforce the strength of the insulating portion (10).

[0102] Additionally, the midplate (50) can also perform a shielding function for the contact portion (20).

[0103] This midplate (50) can be integrated into the insulating portion (10) by insert molding as in one embodiment of the present invention, and of course, it can also be a structure that is separated and combined as needed.

[0104] Meanwhile, the midplate (50) can be formed to be positioned inside the first insulating portion (10a) and the second insulating portion (10b), and the midplate (50) can be positioned between the first contacts (20a) positioned on the upper surface of the insulating portion (10) and the second contacts (20b) positioned on the lower surface of the insulating portion (10).

[0105] Accordingly, the midplate (50) can reinforce the strength of the insulating portion (10) while also performing a shielding function for the first contact (20a) and the second contact (20b) arranged in the insulating portion (10).

[0106] In other words, the midplate (50) can cause the signal flowing through the first contact (20a) to flow to the ground rather than the second contact (20b) when the signal is emitted, thereby blocking interference between the signal flowing through the first contact (20a) and the signal flowing through the second contact (20b).

[0107] And, the midplate (50) can be completely wrapped and protected together with the first contact (20a) and the second contact (20b) constituting the contact portion (20) through a waterproofing member (70) potted in the potting area (S2) described above (see FIG. 7c).

[0108] And, the midplate (50) can be grounded by being mounted on the substrate in the second insulating portion (10b).

[0109] Meanwhile, the waterproofing material (70) potted in the potting area (S2) can implement a waterproof structure by sealing the internal space of the EMC pad (100).

[0110] This waterproofing member (70) can be formed by applying a potting liquid such as silicone to the inside of the potting area (S2) of the potting part (130) while the insulating part (10) to which the contact part (20) is combined is inserted into the EMC pad (100) and then curing it.

[0111]

[0112] Meanwhile, referring again to FIGS. 2 and 8 to 13, the EMC pad (100) provided in the receptacle connector (1) according to one embodiment of the present invention will be examined in more detail as follows.

[0113] As shown, the EMC pad (100) is coupled to the insulating portion (10) and has a structure that can protect the insulating portion (10) while improving shielding and EMC performance.

[0114] For this purpose, the EMC pad (100) may largely include a contact portion (110), a body portion (120), and a potting portion (130).

[0115] First, the contact portion (110) performs a shielding function by making contact with the plug connector and grounding it when the plug connector is inserted into the receptacle connector (1), and can be placed on the surface of the insulating portion (10).

[0116] This contact portion (110) may include an upper contact portion (110a) disposed on the upper surface of the insulating portion (10) and a lower contact portion (110b) disposed on the lower surface of the insulating portion (10).

[0117] And, the body part (120) connects the upper contact part (110a) and the lower contact part (110b) so that it can be easily assembled to the insulation part (10), and one end of the upper contact part (110a) and the lower contact part (110b), and in the case of the second direction, the rear end thereof, is seamlessly connected and can have the shape of a closed curve.

[0118] This body part (120) may have a plate shape corresponding to the front of the stopper block (12) of the insulating part (10), and as it is made of a material stronger than the insulating part (10), it may reinforce the stopper block (12) and perform a stopper function that limits the insertion distance of the plug connector together with the stopper block (12).

[0119] Additionally, the body part (120) may have a cylindrical shape with a sealing member (60) provided on the outer surface while surrounding the insulating part (10).

[0120] In a specific embodiment, the body portion (120) may include a cylindrical first body (120a) that seamlessly connects the ends of the upper contact portion (110a) and the lower contact portion (110b) and has a length (b1, FIG. 8) set in the second direction, and a plate-shaped second body (120b) that extends from the first body (120a) and covers one surface of the stopper block (12).

[0121] At this time, a sealing member (60) may be further included along the outer surface of the first body (120a) (see FIG. 1 and FIG. 7(a)(b)).

[0122] At this time, the second body (120b) can further form a sealing member groove (121) in which the sealing member (60) described above is seated along the shape of the first body (120a) (see Fig. 8). This sealing member groove (121) has a closed curve shape and can prevent the seated sealing member (60) from being detached due to external force.

[0123] Next, the potting portion (130) can extend in the opposite direction from the contact portion (110) in the body portion (120) to surround the outer surface of the stopper block (12) of the insulating portion (10) and form a potting area (S2) therein.

[0124] Specifically, the potting portion (130) may have a cylindrical shape having a length (r2) longer than the length (r1) in the second direction of the stopper block (12), and the stopper block (12) may be accommodated therein.

[0125] And, the potting section (130) can form a potting area (S2) in a space of length (a, Fig. 7a) excluding the length (r1) of the stopper block (12) in the second direction rearward of the stopper block (12).

[0126] This potting zone (S2) may be a space between the stopper block (12) and the second insulating portion (10b), as confirmed in Fig. 7(a), and through a potting process, a potting liquid such as silicone may be injected into the potting zone (S2) and hardened to fill the waterproofing member (70).

[0127] Meanwhile, the EMC pad (100) can be formed by seamlessly connecting the contact portion (110), the body portion (120), and the potting portion (130) through a drawing method, and the rear end (131, Fig. 7a) of the potting portion (130) in the second direction can be formed in a shape that is bent outward by the forming process.

[0128] At this time, the cover (40) covering the EMC pad (100) can further form an end groove (45) on one side of the inner surface into which the rear end (131) described above is fitted or received.

[0129] This end groove (45) can prevent scratches on the cover (40) caused by the rear end (131) when the cover (40) is combined, and can play a role in guiding the cover (40) to be stably combined in the correct position when the EMC pad (100) and the cover (40) are combined.

[0130] And, the EMC pad (100) can be assembled and joined to the insulating portion (10) in the second direction in the longitudinal direction as shown in FIGS. 12 and 13. However, it is not limited thereto, and it goes without saying that the insulating portion (10) and the EMC pad (100) can be insert molded as needed.

[0131] Preferably, the EMC pad (100) can be formed of a metal material having a higher strength than the insulating portion (10).

[0132] Meanwhile, the contact portion (110) constituting the EMC pad (100) may be disposed on the insulating portion (10) with a gap spaced apart from the first contact (20a) and the second contact (20b) exposed to the outside so as to prevent interference with the first contact (20a) and the second contact (20b) disposed on the insulating portion (10) (see FIG. 13).

[0133] Referring to FIG. 10 and FIG. 13, as an example, the upper contact portion (110a) and the lower contact portion (110b) of the contact portion (110) constituting the EMC pad (100) have a plate shape and are placed on the insulating portion (10).

[0134] Meanwhile, as described above, the contact portions (20) arranged on the upper and lower surfaces of the insulating portion (10) may have a structure in which some portions function as signal terminals and others function as power terminals, as needed.

[0135] In addition, as described above, the receptacle connector (1) of the present invention has a waterproof function through the waterproof member (70), but water may penetrate from the outside through the exposed space to the contact block (11) side of the insulating portion (10).

[0136] At this time, if the distance between the contact part (20) that acts as the power terminal and the contact part (110) is close, the movement path may be short and a short circuit may occur.

[0137] Additionally, a short circuit may occur when a high current is applied to the receptacle connector (1).

[0138] To prevent this, the contact portion (110) of the EMC pad (100) may further include a concave escape groove (115) formed toward the body portion (120) to form a gap (d1, Fig. 10) further apart from the contact portion (20) that serves as a power terminal.

[0139] Specifically, referring to FIG. 10, the contact portion (110) may include a main plate (111) having a width in a first direction and a length in a second direction and arranged to be in contact with the insulating portion (10), a first protrusion (112) and a second protrusion (113) extending from both sides of the main plate (111) toward the contact portion (20) exposed externally to make contact with the plug connector, and a third protrusion (114) extending from the main plate (111) toward the contact portion (20) exposed externally to make contact with the plug connector, with a gap from the first protrusion (112) and the second protrusion (113).

[0140] The first protrusion (112), the second protrusion (113), and the third protrusion (114) are in contact with a shielding member (not shown) of the plug connector, and the contact portion (110) including the main plate (111) can block and shield noise so as not to interfere with the signaling of the contact portion (20).

[0141] And, the escape groove (115) described above can be formed between the first protrusion (112) and the third protrusion (114) and between the second protrusion (113) and the third protrusion (114).

[0142] Meanwhile, in the city, the escape groove (115) is shown as being formed in two between each of the first protrusion (112), the second protrusion (113), and the third protrusion (114), but it is not limited thereto, and the position of the escape groove (115) can be formed to avoid the contacts (20a, 20b) that serve as power terminals, as far as possible outside the area where the contact portion (20) makes contact when the plug connector and the receptacle connector are coupled. Accordingly, the escape groove (115) can be formed in multiple numbers, or it can be formed in the form of a single groove.

[0143] In addition, the shape of this escape home (115) is not limited, and it can have various shapes as needed, such as a semicircle, an ellipse, or a polygon.

[0144] In addition, in FIG. 10, the second protrusion (113) is shown to have a length d2 shorter than the first protrusion (112) and the third protrusion (114), but this is only one embodiment, and the first protrusion (112), the second protrusion (113), and the third protrusion (114) may have the same length or different lengths as long as interference with the contact portion (20) can be prevented while EMC performance can be improved.

[0145] Meanwhile, the upper contact portion (110a) and the lower contact portion (110b) forming the contact portion (110) can form a round surface (R, Fig. 11) at the end on the second direction side, in the direction in which the plug connector is inserted.

[0146] Accordingly, when the plug connector is inserted into the receptacle connector (1), the plug connector can be prevented from being damaged or broken by being scratched by a collision.

[0147] Meanwhile, the upper contact portion (110a) and the lower contact portion (110b) forming the contact portion (110) may preferably be formed to have the same size and shape. However, this is not limited to this, and it goes without saying that the shapes may have different sizes and shapes as needed.

[0148] Next, the body part (120) of the EMC pad (100) may have a closed curve shape by seamlessly connecting one end of the upper contact part (110a) and the lower contact part (110b).

[0149] In one embodiment, the body portion (120) may include a cylindrical first body (120a) that seamlessly connects the ends of the upper contact portion (110a) and the lower contact portion (110b) and has a length (b1) set in the second direction, and a plate-shaped second body (120b) that extends from the first body (120a) and covers one surface of the stopper block (12).

[0150] As already described above, the first body (120a) may be provided with a sealing member (60) on the outer surface, and the second body (120b) may cover the stopper block (12) by covering the front surface in the second direction.

[0151] In other words, the second body (120b) may have a plate shape and may have a shape corresponding to one side of the stopper block (12) placed on the front side in the second direction in the direction in which the plug connector is inserted.

[0152] The EMC pad (100) is formed seamlessly and has rigidity through a drawing method using a metal material. The second body (120b) of the body portion (120) may be placed on the front of the stopper block (12) to prevent damage to the insulation portion (10) due to impact when the plug connector is inserted and coupled.

[0153] In addition, the body part (120) can, of course, serve as a stopper to limit the insertion distance of the plug connector together with the stopper block (12).

[0154] Next, the potting portion (130) of the EMC pad (100) may be a cylindrical shape that extends from the body portion (120) in a direction opposite to the contact portion (110) as described above and surrounds the outer surface of the stopper block (12) of the insulating portion (10), specifically the first insulating portion (10a).

[0155] This potting section (130) may preferably have a cylindrical shape having a length (r2, FIG. 7a) longer in the second direction by a than the length (r1) of the stopper block (12) in the second direction, and the stopper block (12) may be accommodated therein and a potting area (S2) may be formed at the rear of the stopper block (12) in the second direction.

[0156] Meanwhile, as described above, the potting zone (S2) may be a space between the stopper block (12) of the insulating section (10) and the second insulating section (10b), and the potting zone (S2) is filled with potting liquid to form a waterproof member (70).

[0157] In this way, the EMC pad (100) including the contact portion (110), the body portion (120), and the potting portion (130) can be combined in a manner of being assembled to the insulating portion (10) as shown in FIGS. 12 and 13.

[0158] And, the EMC pad (100) applied to the receptacle connector (1) according to one embodiment of the present invention has a structure that is grounded.

[0159] For this purpose, the EMC pad (100) can be connected to the cover (40) through welding and grounded.

[0160] And, as confirmed through FIGS. 1 to 13, the receptacle connector (1) according to one embodiment of the present invention has a structure including an insulating portion (10) equipped with a contact portion (20), an EMC pad (100), and a cover (40), and can protect the insulating portion (10) and maintain the outer shape by using the EMC pad (100) for electromagnetic shielding and EMC performance improvement, thereby minimizing the thickness (h, FIG. 6) in the third direction and implementing thinning.

[0161] In other words, a thinner structure can be achieved by removing a separate component, such as a shell, that wraps and protects the conventional insulating part (10).

[0162]

[0163] As described above, the receptacle connector (1) according to one embodiment of the present invention can improve the electromagnetic shielding performance of the contact portion (20) by including an EMC PAD (100) and further enhance the EMC performance.

[0164] In addition, the receptacle connector (1) can be made thinner and thinner by being provided with an EMC pad (100) excluding the conventional shell (not shown) that surrounds the outside of the insulating portion (10).

[0165] In addition, the EMC pad (100) has a structure in which the upper contact portion (110a) and the lower contact portion (110b) are integrally connected without a break by the body portion (120), so that it can be assembled to the insulating portion (10) in a single process of joining them in the longitudinal direction of the insulating portion (10), making assembly easy.

[0166] In addition, the EMC pad (100) has a potting area (S2) formed inside through a potting portion (130) having a length in the second direction and having an extended cylindrical shape, and the waterproofing performance can be improved by eliminating micro-cracks and implementing a waterproofing function through a waterproofing member (70) filled in the potting area (S2).

[0167] In addition, the EMC pad (100) can increase waterproof performance by including a sealing member (60) provided on the outer surface of the first body (120a) of the body portion (120) to increase watertightness between the plug connector and the EMC pad (100).

[0168] In addition, the EMC pad (100) can prevent electromagnetic interference such as short circuits by forming a gap between the contact portion (20) and the escape groove (115) formed in the upper contact portion (110a) and the lower contact portion (110b).

[0169] Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
