Description

Technical Field

[0001] The present invention relates to an RF plug connector, an RF receptacle connector, and an RF connector, and more particularly, to an RF connector having an EMI suppression function for high frequencies.

Background Art

[0002] The electric circuits of various electronic devices are embodied on circuit boards. An electronic device includes a plurality of circuit boards, and the circuit boards are electrically connected to each other. Connectors are used to electrically connect the electronic components and circuit boards that make up the electronic device.

[0003] A connector can be composed of a plug connector and a receptacle connector. The receptacle connector is mounted on a circuit board, the plug connector is coupled to a cable, and the plug connector is fastened to the receptacle connector so that the cable and the circuit board or the circuit boards are electrically connected to each other.

[0004] Such a connector assembly is also widely used in ultra-high-speed wireless communication devices such as 5G, and better electromagnetic wave shielding performance is required as the frequency increases. However, conventional RF connectors cannot exhibit the electromagnetic wave shielding performance required at high frequencies. In particular, when a single connector simultaneously connects a large number of cables and a circuit board, there is a problem of being vulnerable to electromagnetic wave interference between the cables and between the signal pins within the connector.

[0005] As a technology related to the present invention, a connector and a connector device disclosed in a Korean Patent Publication include a plug shield and a receptacle shield, but lack means for shielding between a plurality of plug pins or between a plurality of receptacle pins. The present invention is distinguished from both inventions in terms of having a structure for shielding between a plurality of terminals in terms of configuration and effect.

[0047] Furthermore, in describing the present invention below, detailed explanations of configurations that are deemed likely to obscure the gist of the invention, such as prior art and other known technologies, may be omitted.

[0048] Embodiments of the present invention will be described in detail below with reference to the relevant drawings. Figure 1 is an illustrative diagram of an RF connector according to one embodiment of the present invention, and Figure 2 is a drawing showing the RF plug connector 100 and the RF receptacle connector 200 of the RF connector shown in Figure 1.

[0049] Referring to Figures 1 and 2, an RF connector according to one embodiment of the present invention is depicted in a three-dimensional space represented by three axes: horizontal (X1-X2), vertical (Y1-Y2), and vertical (Z1-Z2). The RF connector is divided into multiple partitions according to rows and columns.

[0050] An RF connector may include an RF plug connector 100 and an RF receptacle connector 200. The RF plug connector 100 is a male connector, and the RF receptacle connector 200 is a female connector. Therefore, the RF plug connector 100 and the RF receptacle connector 200 are electrically and mechanically connected to and disconnected from each other.

[0051] Figure 3 is a diagram showing the RF plug connector 100. Referring to Figure 3, the RF plug connector 100 may include plug pins 110, a plug body 120, a plug shell 130, and a plug shielding wall 140.

[0052] The plug shielding wall 140 is located inside the plug shell 130. The plug body 120 is located inside the plug shielding wall 140. The plug shielding wall 140 forms multiple partitions (S1 in Figure 7), and each partition is provided with a plug pin 110. For example, the plug body 120 forms six partitions (S1), and six plug pins 110 are placed one in each partition (S1).

[0053] The plug body 120 is formed by double injection molding with the plug shielding wall 140 and plug pins 110 already in place. This allows the plug shielding wall 140 and plug pins 110 to be formed to bond with the plug body 120 during the molding process.

[0054] Figure 4 is a diagram showing the plug pin 110. Referring to Figure 4, the plug pin 110 makes electrical contact with the receptacle pin 210. The plug pin 110 is divided into a first part 111 and a second part 112. The first part 111 is the horizontal component of the plug pin 110, and the second part 112 is the vertical component of the plug pin 110, both of which include a surface that connects to the plug body 120. The second part 112 may include a first contact surface (C1) that is bent at the first part 111 and comes into contact with the receptacle pin 210.

[0055] Referring again to Figure 2, as the first contact surface (C1) of the plug pin 110 comes into contact with the receptacle pin 210, the plug pin 110 can be subjected to forces in the directions of Z2 and X1. Therefore, the inner surface of the second part 112 is in contact with and supported by the plug body 120, and at least a portion of the outer surface of the first part 111 is also in contact with and supported by the plug body 120, so that the plug pin 110 does not detach from the plug body 120. In particular, the bending portion that receives the most force may be formed inside the plug body 120.

[0056] Figure 5 is a diagram showing the plug body 120. Referring to Figure 5, the plug body 120 has a first mounting portion 121 on its upper surface on which the plug pin 110 is placed. The plug body 120 may also include a first groove (G1) formed in a concave shape on its side. The first groove (G1) is arranged along the perimeter of the plug body 120. The first groove (G1) is the place where the plug shielding wall 140 is inserted.

[0057] On the other hand, the plug body 120 may include a first protrusion 122 and a first recess 123.

[0058] The first protrusion 122 is a portion of the plug body 120 that protrudes relatively downward, and the first recess 123 is a portion of the plug body 120 that is formed to be more concave than the first protrusion 122. The first protrusion 122 and the first recess 123 are for assembly with the receptacle body 220.

[0059] Figure 6 is a perspective view of the plug shell 130. Referring to Figure 6, the plug shell 130 is manufactured separately from the plug body 120, plug pin 110, and plug shielding wall 140. The plug shell 130 may have a rectangular frame shape formed by combining vertical and horizontal walls. The plug shell 130 may include a second groove (G2) and a third groove (G3). The second groove (G2) may be formed concavely on the lower surface of the vertical wall of the plug shell 130. Multiple second grooves (G2) may be arranged. The third groove (G3) may be formed concavely on the upper surface of the horizontal wall of the plug shell 130. Such second grooves (G2) and third grooves (G3) are for coupling with the plug shielding wall 140.

[0060] Figure 7 is a perspective view showing the plug shielding wall 140, and Figure 8 is a plan view of the plug shielding wall 140 shown in Figure 7.

[0061] Referring to Figures 7 and 8, the plug shielding wall 140 may include a plurality of first vertical walls 141 and a plurality of first horizontal walls 142. The plurality of first vertical walls 141 are arranged at regular intervals. The plurality of first horizontal walls 142 are arranged at regular intervals.

[0062] The first vertical wall 141 is arranged to intersect with at least two first horizontal walls 142. The first horizontal walls 142 are arranged to intersect with at least two first vertical walls 141. The first vertical walls 141 and first horizontal walls 142 are arranged in a grid to form an inwardly closed partition (S1). The plug pin 110 is located in such a partition (S1). The first vertical walls 141 and the first horizontal walls 142 have the same thickness. The upper ends of the first vertical walls 141 and the upper ends of the first horizontal walls 142 may be located on the same plane.

[0063] The plug shielding wall 140 places the plug pin 110 inside and forms a partition (S1) surrounding the plug pin 110, thereby shielding the EMI (electromagnetic interference) generated at the plug pin 110. Specifically, when viewed from a vertical direction, the first vertical wall 141 and the first horizontal wall 142 are arranged to surround the plug pin 110 without any gaps, thereby effectively shielding the EMI generated at the plug pin 110.

[0064] The plug shielding wall 140 may include first projections (P1) protruding from the inner walls of the first vertical wall 141 and the first horizontal wall 142, respectively. The first projections (P1) are inserted into the first groove (G1) of the plug body 120 to increase the bonding force between the plug body 120 and the plug shielding wall 140. By the contact of the first projections (P1) with the first groove (G1), the contact area between the plug shielding wall 140 and the plug body 120 is increased, and the first projections (P1) catch on the first groove (G1) in the vertical direction, thereby increasing the bonding force between the plug body 120 and the plug shielding wall 140.

[0065] The plug shielding wall 140 may include a second projection (P2) and a third projection (P3). The second projection (P2) and the third projection (P3) each protrude from the outer surface of the plug shielding wall 140. The second projection (P2) protrudes from the outer surface of the first vertical wall 141, and the third projection (P3) protrudes from the outer surface of the first horizontal wall 142. Multiple second projections (P2) and third projections (P3) are arranged. The positions of the second projections (P2) and third projections (P3) in the vertical direction may differ from each other. For example, the second projection (P2) may be positioned adjacent to the lower end of the first vertical wall 141, and the third projection (P3) may be positioned adjacent to the upper end of the first horizontal wall 142.

[0066] These second projections (P2) and third projections (P3) are for coupling the plug shielding wall 140 and the plug shell 130. The second projection (P2) is positioned in the second groove (G2) of the plug shell 130, and the third projection (P3) is positioned in the third groove (G3) of the plug shell 130.

[0067] The plug shielding wall 140 is shaped to form a closed partition (S1) when viewed from a vertical direction.

[0068] The plug shielding wall 140 may include a body (BO) made of resin material and a coating layer (CT) coated on the surface of the body (BO). The coating layer (CT) may be made of metal material. Because the body (BO) is formed through molding, it is easy to realize a lattice frame shape. Because the first vertical wall 141 and the first horizontal wall 142 of the plug shielding wall 140 are integrally formed from resin material, it is possible to reduce weight, there are no joints to prevent electromagnetic (EM) leakage, and the shielding performance is not reduced by the addition of a metal coating layer.

[0069] Figure 9 is a diagram showing the RF receptacle connector 200. Referring to Figure 9, the RF receptacle connector 200 may include a receptacle pin 210, a receptacle body 220, a receptacle shell 230, and a receptacle shielding wall 240.

[0070] The receptacle shielding wall 240 is located inside the receptacle shell 230. The receptacle body 220 is located inside the receptacle shielding wall 240. The receptacle body 220 forms multiple partitions (S1), and each partition (S1) is provided with a receptacle pin 210. For example, the plug body 120 forms six partitions (S1), and six receptacle pins 210 are provided one in each partition (S1).

[0071] The receptacle body 220 is formed by double injection molding with the receptacle shielding wall 240 and the receptacle pin 210 positioned together. As a result, during the molding process of the receptacle body 220, the receptacle shielding wall 240 and the receptacle pin 210 can be formed to bond with the receptacle body 220.

[0072] Figure 10 is a diagram showing the receptacle pin 210. Referring to Figure 10, the receptacle pin 210 makes electrical contact with the plug pin 110. The receptacle pin 210 is divided into a third part 211 and a fourth part 212. The third part 211 is the portion that connects to the receptacle body 220. The fourth part 212 may include a second contact surface (C2) that is bent in the third part 211 and contacts the plug pin 110. The fourth part 212 may have a curved shape so that the second contact surface (C2) contacts the first contact surface (C1) of the plug pin 110. Since the fourth part 212 deforms in the X-axis direction due to elastic force during contact with the plug pin 110, it is desirable that a space is formed around the fourth part 212 that is not filled by the receptacle body 220.

[0073] Figure 11 is a diagram showing the receptacle body 220. Referring to Figure 11, the receptacle body 220 has a second mounting portion 221 on its upper surface on which the receptacle pin 210 is placed. The receptacle body 220 may also include a fourth groove (G4) formed in a concave shape on its side. The fourth groove (G4) is located around the receptacle body 220. The fourth groove (G4) is the location where the receptacle shielding wall 240 is inserted.

[0074] On the other hand, the receptacle body 220 may include a second protrusion 222 and a second recess 223.

[0075] The second protrusion 222 is a portion of the receptacle body 220 that protrudes relatively upward, and the second recess 223 is a portion of the receptacle body 220 that is formed to be more concave than the second protrusion 222. The second protrusion 222 and the second recess 223 are for assembly with the plug body 120.

[0076] The shape of the plug body 120 or receptacle body 220 is suitable for securing the plug pin 110 and receptacle pin 210 to their respective bodies, for creating space around the fourth part 212 of the receptacle pin 210, and for enhancing the bonding force between them, exhibiting a "U" or "L" shape.

[0077] Figure 12 is a perspective view of the receptacle shell 230. Referring to Figure 12, the receptacle shell 230 is manufactured separately from the receptacle body 220, the receptacle pin 210, and the receptacle shielding wall 240. The receptacle shell 230 forms a space inside which the RF plug connector 100 is housed. The RF plug connector 100 is housed inside the receptacle shell 230.

[0078] The receptacle shell 230 may include holes 231. The holes 231 may be located on the underside of the vertical wall of the receptacle shell 230 and may be formed to penetrate the inside and outside of the receptacle shell 230. Multiple holes 231 may be provided. Such holes 231 are for connection with the receptacle shielding wall 240.

[0079] The bottom surface of the receptacle shell 230 is in contact with the receptacle shielding wall 240 and functions as a shielding wall. The bottom surface of the receptacle shell 230 may have a shape corresponding to the receptacle shielding wall 240. For example, the bottom surface of the receptacle shell 230 may be arranged to form a grid, corresponding to the receptacle shielding wall 240 which is arranged to form a grid.

[0080] Figure 13 is a diagram showing the receptacle shielding wall 240. Referring to Figure 13, the receptacle shielding wall 240 may include a plurality of second vertical walls 241 and a plurality of second horizontal walls 242. The plurality of second vertical walls 241 are arranged at regular intervals.

[0081] The second vertical wall 241 is arranged to intersect with at least two second horizontal walls 242. The second horizontal walls 242 are arranged to intersect with at least two second vertical walls 241. Such second vertical walls 241 and second horizontal walls 242 are arranged in a grid to form an inwardly closed partition (S2). The receptacle pin 210 is located in such a partition (S2). The second vertical wall 241 and the second horizontal walls 242 have the same thickness. The upper ends of the second vertical wall 241 and the upper ends of the second horizontal walls 242 may be located on the same plane.

[0082] The receptacle shielding wall 240 places the receptacle pin 210 inside and forms a partition (S2) surrounding the receptacle pin 210, thereby shielding the EMI generated by the receptacle pin 210. Specifically, when viewed from a vertical direction, the second vertical wall 241 and the second horizontal wall 242 are arranged to surround the receptacle pin 210 without any gaps, thereby effectively shielding the EMI generated by the receptacle pin 210.

[0083] The receptacle shielding wall 240 may include a plurality of fourth projections (P4) protruding from its outer surface. The fourth projections (P4) are inserted into the holes 231 of the receptacle shell 230 to enhance the bonding force between the receptacle shell 230 and the receptacle shielding wall 240.

[0084] Such a receptacle shielding wall 240 is shaped to include a grid that, when viewed from a vertical direction, forms a closed partition (S2), similar to the plug shielding wall 140.

[0085] The receptacle shielding wall 240 is formed by punching a metal plate to create a partition (S2).

[0086] Figure 14 is a side cross-sectional view of the RF connector with reference to AA in Figure 1; Figure 15 is a diagram showing the state in which the plug pin 110 and the receptacle pin 210 are in contact; Figure 16 is a diagram showing the process of assembling the plug body 120 and the receptacle body 220; and Figure 17 is a side cross-sectional view of the RF connector with reference to BB in Figure 1.

[0087] Referring to Figures 14 to 17, with the RF plug connector assembled to the RF receptacle connector 200, the partition (S2) of the RF receptacle connector 200 and the partition (S1) of the RF plug connector are aligned to form a single independent partition (S1, S2). Then, with the plug pins 110 and the receptacle pins 210 aligned, they make contact with each other in the contact area.

[0088] Once the RF plug connector is assembled to the RF receptacle connector 200, a plug body 120 and a receptacle body 220 are assembled for each independent partition (S1, S2). The first protrusion 122 of the plug body 120 is assembled to the second recess 223 of the receptacle body 220, and the second protrusion 222 of the receptacle body 220 is assembled to the first recess 123 of the plug body 120.

[0089] In this way, during the assembly process of the plug body 120 and the receptacle body 220, the first contact surface (C1) of the plug pin 110 and the second contact surface (C2) of the receptacle pin 210 come into contact at each independent partition (S1, S2), thereby electrically connecting the RF plug connector to the RF receptacle connector 200.

[0090] The plug pin 110 and the receptacle pin 210 are located inside the independent partition (S1). The independent partition (S1) is surrounded by the plug shielding wall 140 and the receptacle shielding wall 240, preventing EMI inside the independent partition (S1) from being emitted to the outside of the partition (S1). In other words, EMI is shielded within each individual partition (S1).

[0091] The thickness (t1) of the plug shielding wall 140 is relatively greater than the thickness (t2) of the receptacle shielding wall 240.

[0092] In Figure 14, L1 is a reference line indicating the contact area between the plug pin 110 and the receptacle pin 210, and L2 is a reference line indicating the contact area where the lower end of the plug shielding wall 140 and the upper end of the receptacle shielding wall 240 come into contact.

[0093] A reference line (L2) indicating the contact area where the lower end of the plug shielding wall 140 and the upper end of the receptacle shielding wall 240 abut is positioned lower than a reference line (L1) indicating the contact area between the plug pin 110 and the receptacle pin 210.

[0094] The thickness of the plug shielding wall 140 (t1 in Figure 7) is made sufficient to cover the contact area between the plug pin 110 and the receptacle pin 210. This is because the vertical positions of the contact area between the plug pin 110 and the receptacle pin 210 and the contact area where the lower end of the plug shielding wall 140 and the upper end of the receptacle shielding wall 240 abut are different, thus maximizing the prevention of EMI leakage at the point where the plug shielding wall 140 and the receptacle shielding wall 240 abut.

[0095] On the other hand, the receptacle shell 230 is positioned to cover the contact area where the lower end of the plug shielding wall 140 and the upper end of the receptacle shielding wall 240 abut. Such a receptacle shielding wall 240 can prevent EMI leakage between the lower end of the plug shielding wall 140 and the gap between the receptacle shielding wall 240.

[0096] Furthermore, the plug body 120 and the receptacle body 220 are arranged such that the receptacle shell 230 covers the contact area where the lower end of the plug shielding wall 140 and the upper end of the receptacle shielding wall 240 abut, thereby preventing EMI leakage between the lower end of the plug shielding wall 140 and the gap in the receptacle shielding wall 240.
