[0025] In this embodiment, a coaxial cable is used as an example of the cable 300 to be coupled to the plug connector 100. However, instead of a coaxial cable, the cable 300 may be of various other types of cable, such as a data cable, a wire, a Flexible Flat Cable (FFC), or a Flexible Printed Circuit (FPC).

[0026] Cable 300 may include a signal conductor (inner conductor) 310, an outer conductor 330 that shields signal conductor 310 from electromagnetic waves and is made of aluminum, copper, or the like, a dielectric 320 that insulates and separates signal conductor 310 and outer conductor 330, and an outer jacket 340 that protects outer conductor 330. The plug connector 100 includes first and second signal pins 110 a , 110 b , shield cans 120 , 130 , first and second insulating members 140 a , 140 b , and a plug shell 150 .

[0027] In this embodiment, two cables 300 are illustrated, but the number of cables 300 may be one or three or more. When a plurality of cables 300 are used, the cables 300 are arranged in parallel to each other. Those skilled in the art will understand that the number or structure of the first and second signal pins 110a, 110b, the shielding cans 120, 130, the first-first and first-second insulating members 140a, 140b, and the plug shell 150 may be appropriately modified depending on the number of cables 300.

[0028] The first and second signal pins 110a, 110b are provided for each cable 300, and the first and second signal pins 110a, 110b are arranged in parallel to each other, similar to the cable 300. The first and second signal pins 110a, 110b may include rear portions 111a, 111b and front portions 112a, 112b formed integrally with the rear portions 111a, 111b. The rear portions 111a, 111b are formed to be in electrical contact with the signal line 310. For example, the rear portions 111a, 111b may include an insertion portion into which the signal line 310 is inserted, or the rear portions 111a, 111b and the signal line 310 are electrically contacted by, for example, a pin or soldering. The front portions 112a, 112b are formed to elastically contact first and second clip pins 210a, 210b of the receptacle connector 200 described below. For example, the front portions 112a, 112b are approximately JPEG0007599187000001.jpg66" shape.

[0029] The shielding cans 120 and 130 surround the first and second signal pins 110a and 110b such that the front portions 112a and 112b of the first and second signal pins 110a and 110b are exposed downward, and are formed to be electrically isolated from the first and second signal pins 110a and 110b. The shielding cans 120 and 130 may be formed of a metal material for electromagnetic wave shielding. The shielding cans 120 and 130 may include a lower shielding can 120 and an upper shielding can 130. The lower shielding can 120 may have first and second lower mounting grooves 121a and 121b that form a space in which the lower portion of the cable 300 is mounted and the rear portions 111a and 111b of the first and second signal pins 110a and 110b are disposed. The upper shielding can 130 is formed to cover the lower shielding can 120, and may have first and second upper mounting grooves 131a, 131b that form a space in which an upper portion of the cable 300 is mounted and in which rear portions 111a, 111b of the first and second signal pins 110a, 110b are disposed. The upper shielding can 130 may be formed longer forward than the lower shielding can 120 to cover front portions 112a, 112b of the first and second signal pins 110a, 110b. In the present embodiment, the shielding cans 120, 130 are described as being formed by combining the lower shielding can 120 and the upper shielding can 130, but the shielding cans 120, 130 may be formed integrally.

[0030] The lower shielding can 120 may have a vertical through hole 122 disposed between the first and second lower mounting grooves 121a and 121b, and the upper shielding can 130 may have a first protrusion 132 protruding downward to be inserted into the through hole 122. The first protrusion 132 may serve to provide shielding between adjacent cables 300 and between the rear portion 111a of the first signal pin 110a and the rear portion 111b of the second signal pin 110b.

[0031] In addition, the upper shielding can 130 may include a second protrusion 133 protruding downward to be disposed between the front portion 112a of the first signal pin 110a and the front portion 112b of the second signal pin 110b. The second protrusion 133 may provide shielding between the front portion 112a of the first signal pin 110a and the front portion 112b of the second signal pin 110b. According to an embodiment, the shielding cans 120, 130 and the outer conductor 330 of the cable 300 may be coupled by soldering.

[0032] The 1-1 and 1-2 insulating members 140a, 140b are coupled to the first and second signal pins 110a, 110b to insulate the first and second signal pins 110a, 110b from the shielding cans 120, 130. The 1-1 and 1-2 insulating members 140a, 140b may have through holes through which the front portions 112a, 112b of the first and second signal pins 110a, 110b pass, and may be formed to cover the upper portions of the front portions 112a, 112b of the first and second signal pins 110a, 110b and expose the lower portions. The 1-1 and 1-2 insulating members 140a, 140b may be integrally formed by a connecting part therebetween.

[0033] The plug shell 150 is formed to surround the upper and side surfaces of the shielding cans 120 and 130, with a lower portion open so that the front portions 112a and 112b of the first and second signal pins 110a and 110b are exposed downward. The plug shell 150 may be formed of a metal material for electromagnetic shielding. The plug shell 150 may also include a surrounding portion 151 that surrounds and supports a portion of the cable 300 exposed to the outside of the shielding cans 120 and 130 from the rear side of the shielding cans 120 and 130. The surrounding portion 151 extends from the upper portion of the plug shell 150 to the rear side. The surrounding portion 151 may prevent the cable 300 from being excessively bent or detached and damaged. In addition, a plurality of protrusions 134 are formed on the upper surface of the upper shielding can 130, and through holes 152 corresponding to the protrusions 134 are formed on the upper surface of the plug shell 150, and the protrusions 134 are inserted into the through holes 152, so that the plug shell 150 and the upper shielding can 130 can be firmly coupled to each other. Depending on the embodiment, an additional shell may be provided to cover the plug shell 150 in order to improve shielding performance or increase reliability against vibration, etc. Also, although it is shown that there is a gap between the front surface and the side surface of the plug shell 150 in this embodiment, depending on the embodiment, the side surface may be extended and folded toward the front surface, and a portion of the front surface may be surrounded by the extended and folded portion.

[0034] According to the plug connector 100 according to the embodiment of the present invention, electromagnetic waves generated through the signal line 310, the outer conductor 330, and the signal pin 110 of the cable 300 are primarily shielded by the shielding cans 120 and 130, and secondarily shielded by the plug shell 150, thereby improving the electromagnetic wave shielding performance. In addition, electromagnetic waves between adjacent signal lines 310 or between adjacent first and second signal pins 110a and 110b are shielded by the first protrusions 132 and second protrusions 133 of the shielding cans 120 and 130, thereby minimizing interference between signals.

[0035] 3A and 3B are drawings showing a receptacle connector 200 according to one embodiment of the present invention, where FIG. 3A is an exploded view of the receptacle connector 200 from the rear upper side, and FIG. 3B is a view of the exploded view of FIG. 3A from the front lower side.

[0036] The receptacle connector 200 includes first and second clip pins 210a, 210b, a receptacle base 220, first and second insulating members 230a, 230b, and an elastic portion 240.

[0037] The first and second clip pins 210a, 210b are formed so that their lower surfaces are in electrical contact with signal pads (not shown) of a circuit board (designated P in FIG. 4C) through elastic contact or soldering, and their upper surfaces are in elastic contact with front portions 112a, 112b of the first and second signal pins 110a, 110b. For example, the first and second clip pins 210a, 210b are approximately JPEG0007599187000002.jpg58" shape. Depending on the embodiment, the first and second clip pins 210a and 210b may be electrically connected to the signal pads of the circuit board (P) by a surface mount (SMD / SMT) method or a through-type SIP, DIP, QIP, etc.

[0038] Receptacle base 220 is formed to be installed on the upper surface of substrate (P) and provides first and second spaces 221a, 221b to accommodate 2-1 and 2-2 insulating members 230a, 230b and first and second clip pins 210a, 210b. First and second spaces 221a, 221b may be formed to penetrate receptacle base 220 from top to bottom. Receptacle base 220 may be formed of a metal material for electromagnetic shielding and grounding.

[0039] The 2-1 and 2-2 insulating members 230a, 230b are inserted into the first and second spaces 221a, 221b of the receptacle base 220 and surround the first and second clip pins 210a, 210b from the sides to fix the first and second clip pins 210a, 210b and at the same time insulate the first and second clip pins 210a, 210b from the receptacle base 220. The 2-1 and 2-2 insulating members 230a, 230b may be integrally formed by a connecting part 231 therebetween.

[0040] The receptacle base 220 may include a shielding wall 226 disposed between the 2-1st and 2-2nd insulating members 230a, 230b while dividing the first and second spaces 221a, 221b. The shielding wall 226 may serve to shield the first and second clip pins 210a, 210b. A hole 232 may be formed in a connection part 231 between the 2-1st and 2-2nd insulating members 230a, 230b, penetrating vertically. The shielding wall 226 may include a protrusion 227 inserted into the hole 232 and having a lower surface that is approximately flush with a lower surface of the receptacle base 220. The protrusion 227 may be in electrical contact (e.g., by soldering) with a ground pad (not shown) of the circuit board (P). In this way, the shielding wall 226 is grounded, and the shielding effect between the first and second clip pins 210a, 210b is further improved.

[0041] The elastic part 240 is made of a metal or a shielding resin material and is partially formed in a plate shape to have elasticity. The elastic part 240 is attached along a portion of the surface of the receptacle base 220 facing the shielding cans 120, 130 and the plug shell 150 of the plug connector 100. The elastic part 240 improves shielding performance by minimizing a gap between the plug connector 100 and the receptacle base 220 when the plug connector 100 and the receptacle base 220 are coupled. In addition, the elastic part 240 may have a number of cut elastic pieces 241 at a portion facing the shielding cans 120, 130 and the plug shell 150 of the plug connector 100. The elastic pieces 241 may increase the contact force between the plug connector 100, the elastic part 240, and the receptacle base 220 to further improve the shielding performance.

[0042] In order to firmly connect the plug connector 100 and the receptacle connector 200, the receptacle base 220 has a plurality of fastening grooves 224, 225 on its front and side surfaces, and the plug shell 150 has elastic fastening portions 154, 155 corresponding to the fastening grooves 224, 225 on its front and side surfaces, so that the elastic fastening portions 154, 155 are elastically inserted into the fastening grooves 224, 225 when the plug connector 100 and the receptacle connector 200 are connected.

[0043] Figures 4A to 4C are drawings showing a connector assembly in which the plug connector 100 and the receptacle connector 200 are coupled together, where Figure 4A is a drawing of the connector assembly in which the plug connector 100 and the receptacle connector 200 are coupled together, viewed from the front and upper side, Figure 4B is a drawing of the connector assembly in which the plug connector 100 and the receptacle connector 200 are coupled together, viewed from the front and lower side, and Figure 4C is a cross-sectional view of the connector assembly in which the plug connector 100 and the receptacle connector 200 are coupled together.
