[Technical field]

[0001] The present invention relates to an electrical connector, and more particularly to a connector assembly including a receptacle connector and a plug connector, and to the plug connector. [Background technology]

[0002] In many electronic devices (e.g., wired or wireless communication devices, etc.), internal circuits are embodied on a circuit board. To connect the circuit board to other electronic devices or other circuit boards, a connector assembly including a receptacle connector and a plug connector is used.

[0003] The receptacle connector is mounted on a circuit board, and the plug connector is coupled to a cable. When the plug connector is fastened to the receptacle connector, the pins of the plug connector directly and elastically contact the circuit board, electrically connecting the cable and the circuit board.

[0004] Such connector assemblies are also widely used in ultra-high-speed wireless communication devices such as 5G, and the higher the frequency, the better the electromagnetic shielding performance is required. However, conventional connector assemblies cannot exhibit the electromagnetic shielding performance required at high frequencies, and in particular, when multiple cables and circuit boards are simultaneously connected with one connector, there is a problem that they are vulnerable to electromagnetic interference between cables and pins within the connector.

[0005] In addition, when connecting the plug connector to the receptacle connector, the pins of the receptacle connector connected to the contacts of the board must come into contact with the pins of the plug connector, resulting in a complex pin structure. Furthermore, the overall structure of the connector assembly is complex and there are many parts. Summary of the Invention [Problem to be solved by the invention]

[0045] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In the following description and the accompanying drawings, substantially the same components are denoted by the same reference numerals, and duplicated description will be omitted. In addition, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may obscure the gist of the present invention, the detailed description thereof will be omitted.

[0046] In describing components of the embodiments of the present invention, terms such as first, second, A, B, etc. are used. Such terms are used to distinguish the components from other components, and are not intended to limit the essence, order, or sequence of the components.

[0047] FIG. 1 is a perspective view showing a connector assembly according to an embodiment, and FIG. 2 is a perspective view showing a receptacle connector and a plug connector shown in FIG.

[0048] In the drawings, the x-axis indicates the front-rear direction of the connector assembly, the y-axis indicates the left-right direction of the connector assembly, and the z-axis indicates the up-down direction of the connector assembly. In addition, "horizontal" in the present invention indicates a direction parallel to the xy plane.

[0049] In addition, the terms "rear surface" and "rear side" used in this specification refer to the direction facing the cable based on the front-rear direction, while the terms "front surface" and "front side" refer to the opposite direction. In addition, the terms "bottom surface" and "bottom side" used in this specification refer to the direction from the plug connector to the receptacle connector based on the top-bottom direction, while the terms "top surface" and "top side" refer to the opposite direction.

[0050] The connector assembly according to the embodiment includes a receptacle connector 100 and a plug connector 200. The plug connector 200 is connected to a cable 10 in a front-rear direction (x). In describing the embodiment, the cable 10 is described as a coaxial cable, but the cable 10 may be any of various types of cables, such as a data cable, a wire, a flexible flat cable (FFC), a flexible printed circuit (FPC), etc. The receptacle connector 100 and the plug connector 200 are coupled in a vertical direction.

[0051] FIG. 3 is an exploded view showing the receptacle connector 100 shown in FIG.

[0052] 3, the receptacle connector 100 does not include a separate pin, but serves to guide the plug connector 200 so that the plug connector 200 is directly connected to a contact (CP) of a circuit board (1 in FIG. 4).

[0053] The receptacle connector 100 may include a base 110 and an elastic part 120. The base 110 may include a first hole (H1) on the inside. The first hole (H1) penetrates the base 110 in the vertical direction (z). The first hole (H1) is divided into two spaces by a partition wall 111. The base 110 may be made of a metal material for electromagnetic shielding and grounding.

[0054] The elastic part 120 may be made of a metal or a shielding resin material and may be partially formed in a plate shape to have elasticity. The elastic part 120 is attached to the base 110. For example, the elastic part 120 is mounted on a surface of the base 110 in an area facing the shielding can and the plug shell of the plug connector 200.

[0055] The elastic portion 120 improves the shielding performance by minimizing the gap between the plug connector 200 and the base 110 when the plug connector 200 and the receptacle connector 100 are coupled. Also, the elastic portion 120 may have a number of cut elastic pieces 121. The elastic pieces 121 are disposed in portions of the plug connector 200 facing the shielding can and the plug shell. The elastic pieces 121 may increase the contact force between the plug connector 200, the elastic portion 120, and the base 110, thereby further improving the shielding performance.

[0056] FIG. 4 is a plan view of base 110 of receptacle connector 100 shown in FIG.

[0057] 4, the first hole (H1) of the base 110 is partitioned into two spaces aligned in the left-right direction by a partition wall 111. The receptacle connector 100 is mounted on the circuit board 1 so that the contacts (CP) of the circuit board 1 are located in these two spaces, respectively.

[0058] The base 110 is mounted on the circuit board 1 by a surface mount device (SMD / surface mount technology, SMT) method, a through-hole method such as a single in-line package (SIP), a dual in-line package (DIP), or a quad in-line package (QIP), or by a combination of the surface mount method and the through-hole method. Depending on the embodiment, the receptacle connector 100 may be formed integrally with the circuit board 1, rather than being a separate component.

[0059] FIG. 5 is an exploded view of the plug connector 200 shown in FIG.

[0060] 5, a cable 10 may include a signal conductor 11, a cable dielectric 12 disposed on the outside of the signal conductor 11, an outer conductor 13 disposed on the outside of the cable dielectric 12, and an outer jacket 14 disposed on the outside of the outer conductor 13. The cable dielectric 12 insulates and separates the signal conductor 11 from the outer conductor 13. The outer conductor 13 serves to shield the signal conductor 11 from electromagnetic waves. The outer conductor 13 may be made of a metal such as aluminum or copper. And, the outer jacket 14 serves to protect the outer conductor 13.

[0061] The plug connector 200 is directly and electrically connected to the circuit board 1 through the guide of the receptacle connector 100. In addition, the plug connector 200 has a structure that provides double electromagnetic wave shielding.

[0062] Such a plug connector 200 may include pins 210, a dielectric 220, and a shield can 230.

[0063] One side of the pin 210 is electrically connected to the cable 10. The pin 210 may correspond to one cable 10. Therefore, the number of the pins 210 is the same as the number of the cables 10. A plurality of the cables 10 are arranged in parallel in the left-right direction (y), and a corresponding plurality of the pins 210 are arranged in parallel in the left-right direction (y). In the embodiment, the number of the cables 10 is described as two, but the number of the cables 10 may be one, or three or more.

[0064] The signal line 11 of the cable 10 and the pin 210 are connected by forming a structure in which the signal line 11 is inserted into one side of the pin 210, or one side of the pin 210 is shortened or soldered to be electrically connected to the signal line 11 of the cable 10.

[0065] The dielectric 220 fixes the other side of the pin 210 to ensure the rigidity of the pin 210 and serves to guide the movement of the pin 210. The size of the dielectric 220 in the left-right direction (y) can be set to be different depending on the number of the pins 210.

[0066] The shielding can 230 is a member that blocks electromagnetic waves generated from the cable 10. The shielding can 230 may be made of a metal material. The shielding can 230 has a shape that surrounds the connection portion between the cable 10 and the pin 210 as a whole. The shielding can 230 covers the pin 210 such that the front end of the pin 210 is exposed downward. The shielding can 230 and the pin 210 are arranged at a distance from each other.

[0067] The shielding can 230 may include an upper shielding can 231 and a lower shielding can 232. The upper shielding can 231 covers the upper side of the cable 10 and the pin 210. The lower shielding can 232 covers the lower side of the connection portion between the cable 10 and the pin 210. The upper shielding can 231 may be formed longer forward than the lower shielding can 232 so as to cover the front end of the pin 210. The upper shielding can 231 and the lower shielding can 232 may be combined with each other. Although the shielding can 230 has been exemplified as a combination of the upper shielding can 231 and the lower shielding can 232 which are separate items, the present invention is not limited thereto, and the shielding can 230 may be a single member.

[0068] In some embodiments, the shielding can 230 and the outer conductor 13 of the cable 10 may be coupled through soldering.

[0069] When the plug connector 200 is coupled to the receptacle connector 100, the pins 210 directly contact the contacts (CP) of the circuit board 1. When the pins 210 are pressed against the contacts (CP) of the circuit board 1, in order to maintain contact between the pins 210 and the contacts (CP) of the circuit board 1, the pins 210 must have a structure that can be deformed to ensure elasticity.

[0070] FIG. 6 is a side view of the pin 210 shown in FIG.

[0071] 6, the pin 210 may include a contact portion 211, a first region 212, and a second region 213. The contact portion 211, the first region 212, and the second region 213 are only separated for the purpose of describing the function and shape, and are a single member connected to each other.

[0072] The contact portion 211 is a region that comes into contact with a contact point (CP) of the circuit board 1. The contact portion 211 is arranged horizontally. The first region 212 may be formed by being banded from the contact portion 211 in a first direction (for example, counterclockwise in FIG. 6). The first region 212 is arranged along the up-down direction (z) as a whole. And the second region 213 may be formed by being banded from the first region 212 in the first direction. An end of the second region 213 is connected to the cable 10. The second region 213 is arranged parallel to or oblique to the contact portion 211.

[0073] The pin 210 having this configuration has the advantage that a sufficient restoring force can be ensured when the contact portion 211 comes into contact with the contact point (CP) of the circuit board 1.

[0074] The first region 212 is divided into a 1-1 region 212a and a 1-2 region 212b. The 1-1 region 212a is a region that is bent in a counterclockwise direction from the contact portion 211, and the 1-2 region 212b is a region that is bent in a counterclockwise direction from the 1-1 region 212a and connected to the second region 213. Therefore, a part of the first region 212 may have a shape that protrudes forward from the second region 213. This is to increase the restoring force of the pin 210 and to separate the 1-1 region 212a from the dielectric 220 rearward in order to induce elastic deformation of the pin 210 near the contact portion 211.

[0075] 7 is a perspective view of the dielectric 220 shown in FIG. 5, and FIG. 8 is a side cross-sectional view of the dielectric 220 taken along the line DD in FIG.

[0076] 7 and 8, the dielectric 220 fixes the pin 210 to ensure the rigidity of the pin 210. The dielectric 220 also has a feature that the pin 210 is fixed so as to be elastically deformable. The dielectric 220 can guide the movement of the pin 210.

[0077] The dielectric 220 may include a second hole (H2) in which the pin 210 is disposed, and a first groove (G1) and a second groove (G2) communicating with the second hole (H2).

[0078] The second hole (H2) is divided into a 2-1 hole (H21) and a 2-2 hole (H22). The first groove (G1) is disposed between the 2-1 hole (H21) and the 2-2 hole (H22) and communicates with the 2-1 hole (H21) and the 2-2 hole (H22). The first groove (G1) is disposed near the edge between the upper surface and the front surface of the dielectric 220. The second groove (G2) communicates with the 2-2 hole (H22). The second groove (G2) may be formed in a concave shape on the lower surface of the dielectric 220.

[0079] The 2-2 hole (H22) may be formed toward the first groove (G1) on the back surface of the dielectric 220. The 2-1 hole (H21) may be formed toward the second groove (G2) in the first groove (G1). The 2-2 hole (H22) is disposed in the front-back direction (x), and the 2-1 hole (H21) is disposed in the up-down direction (z).

[0080] The dielectric 220 may include a first protrusion (P1) that protrudes upward in a convex shape from the upper surface. The first protrusion (P1) is for coupling with the upper shielding can 231. The first protrusion (P1) is inserted into the third groove (G3 in FIG. 11) of the upper shielding can 231. A plurality of such first protrusions (P1) are arranged. For example, two first protrusions (P1) are arranged spaced apart in the left-right direction (y). However, the present invention is not limited thereto, and conversely, a configuration in which a protrusion is arranged on the upper shielding can 231 and a groove is formed in the dielectric 220 to couple with each other may also be implemented.

[0081] The dielectric 220 may include a fourth groove (G4). The fourth groove (G4) is also for coupling with the upper shielding can 231. The fourth groove (G4) may be formed in a concave shape on the upper surface of the dielectric 220. The fourth groove (G4) is disposed penetrating the rear surface and the front surface of the dielectric 220. The fourth groove (G4) is disposed in the center of the dielectric 220 in the left-right direction (y). The fourth groove (G4) is disposed between two first grooves (G1) in the left-right direction (y).

[0082] Furthermore, dielectric 220 may include a fifth groove (G5). Fifth groove (G5) is for coupling with base 110 of receptacle connector 100. Fifth groove (G5) may be formed in a concave shape on the lower surface of dielectric 220. Fifth groove (G5) is disposed penetrating through the rear surface and front surface of dielectric 220. This fifth groove (G5) is disposed in the center of dielectric 220 in the left-right direction (y).

[0083] FIG. 9 is a perspective view of the dielectric 220 to which the pin 210 is fixed, and FIG. 10 is a side cross-sectional view of the dielectric 220 taken along the line EE in FIG.

[0084] 9 and 10, the contact portion 211 of the pin 210 protrudes in the vertical direction (z) from the bottom surface of the dielectric 220. The 1-1 region 212a of the pin 210 is located in the second groove (G2) and is separated from the dielectric 220 to ensure a deformation space for the contact portion 211. The 1-2 region 212b is inserted into the 2-1 hole of the dielectric 220. The second region 213 is inserted into the 2-2 hole (H22), and the connection portion between the second region 213 and the 1-2 region 212b is exposed by the first groove (G1).

[0085] Such a dielectric 220 fixes the second region 213 in the up-down direction (z) through the 2-2 hole (H22) of the pin 210, and fixes the 1-2 region 212b in the front-to-back direction (x) through the 2-1 hole (H21), thereby fixing the pin 210 not only in the up-down direction (z) but also in the front-to-back direction (x) in accordance with the shape of the pin 210, thereby ensuring the rigidity of the pin 210.

[0086] FIG. 11 is a bottom view of the upper shielding can 231.

[0087] 7 and 11, the upper shielding can 231 may include a second protrusion (P2) protruding from a surface facing the dielectric 220. The second protrusion (P2) is inserted into a fourth groove (G4) of the dielectric 220. The second protrusion (P2) serves to fix the dielectric 220 and to improve the ease of assembly between the dielectric 220 and the shielding can 230. In particular, the second protrusion (P2) is disposed between the front ends of two adjacent pins 210, and thus can prevent signal interference between the adjacent pins 210.

[0088] Meanwhile, the upper shielding can 231 may include a third groove (G3). The first protrusion (P1) of the dielectric 220 is inserted into the third groove (G3). However, the present invention is not limited thereto, and conversely, the upper shielding can 231 may have a protrusion and the dielectric 220 may have a groove formed therein to be coupled to each other.

[0089] FIG. 12 is a cross-sectional view of the connector assembly taken along line AA in FIG.

[0090] 12, when the plug connector 200 is coupled to the receptacle connector 100, the receptacle connector 100 serves to guide the dielectric 220 so that the pins 210 come into contact with the circuit board 1. The front and both sides of the dielectric 220 are disposed facing the inner walls of the first hole (H1), respectively. Therefore, when the plug connector 200 is coupled to the receptacle connector 100, the dielectric 220 is inserted on the inner walls of the first hole (H1), so that the front and both sides of the dielectric 220 can be used as guide surfaces for coupling the receptacle connector 100 and the plug connector 200.

[0091] FIG. 13 is a cross-sectional view of the connector assembly taken along line BB in FIG.

[0092] 13, with plug connector 200 coupled to receptacle connector 100, bulkhead 111 disposed on base 110 of receptacle connector 100 is inserted into fifth groove (G5) of dielectric 220, thereby ensuring assembly between dielectric 220 and base 110 of receptacle connector 100. In addition, as bulkhead 111 moves along fifth groove (G5), the positions of pins 210 and contacts (CP) of circuit board 1 are aligned.

[0093] 14 is a cross-sectional view of the connector assembly taken along the line CC in FIG. 1, and FIG. 15 is an exploded view of the plug connector 200 as viewed from below.

[0094] 14 and 15, the upper shielding can 231 may include an upper mounting groove 231a. The upper mounting groove 231a is disposed on an inner surface of the upper shielding can 231 facing the cable 10, and an upper side of the cable 10 is mounted in the upper mounting groove 231a. The lower shielding can 232 may include a lower mounting groove 232a. The lower mounting groove 232a is disposed on an inner surface of the lower shielding can 232, and a lower side of the cable 10 is mounted in the lower mounting groove 232a.

[0095] The upper shielding can 231 may include a third protrusion P3 protruding from a surface facing the cable 10. The third protrusion P3 is inserted into the through hole 232b of the lower shielding can 232. The third protrusion P3 is disposed between two adjacent cables 10 to shield the space between the adjacent cables 10, and is disposed between rear ends of adjacent pins 210 to shield the space between the rear ends of the adjacent pins 210. In addition, the third protrusion P3 serves to connect the upper shielding can 231 and the lower shielding can 232 by being inserted into the through hole 232b.

[0096] FIG. 16 is a perspective view showing the receptacle connector 100. As shown in FIG.

[0097] 15 and 16, the plug connector 200 may include a plug shell 240. The plug shell 240 is disposed outside the shielding can 230.

[0098] The plug shell 240 is open at the bottom so that the front end of the pin 210 is exposed downward, and is formed to surround the top and side surfaces of the shielding can 230. The plug shell 240 may be made of a metal material for electromagnetic shielding. The plug shell 240 may also include a surrounding part 241 that surrounds and supports a part of the cable 10 exposed outside the shielding can 230 at the rear side of the shielding can 230. The surrounding part 241 extends from the top of the plug shell 240 to the rear side. The surrounding part 241 may prevent the cable 10 from being excessively bent or detached and damaged.

[0099] The plug shell 240 may include elastic fastening portions 242, 243 disposed on a front surface and both sides. The receptacle base 110 may include a plurality of fastening grooves 112, 113 to which the elastic fastening portions 242, 243 are fastened on a front surface and both sides.
