In addition, a portion of the plug connector 200 is inserted into the receptacle shield 150 and the receptacle socket 110 coupled to the receptacle shield support portion 140, so that the plug connector 200 and the receptacle connector 100 are connected to each other. A second plug receiving space 134 that is coupled can be formed.

The second plug receiving space 134 has an opening opposite to the extended portion of the receptacle base 130, and a portion of the plug connector 200 can be accommodated through the opened portion to be coupled or removed.

The receptacle shield 150 may be combined with the receptacle insulator 102 to reinforce the rigidity of the receptacle insulator 102. Additionally, the receptacle shield 150 is coupled to the module substrate (not shown) while being coupled to the receptacle insulator 102 to increase the coupling force between the receptacle connector 100 and the module substrate (not shown).

The receptacle shield 150 is mounted on the PCB pattern of the board and shields the radiation of the receptacle RF contact 180 signal received inside the connector to the outside, and shields noise or various signals coming from the outside, thereby preventing the RF signal from being transmitted. Blocks unnecessary external radiation or unnecessary external signal inflow to ensure that RF signals are transmitted and received normally.

The receptacle shield 150 can be formed by bending according to the shape of the receptacle insulator 102, and as shown in FIG. 3, it is formed according to the shape of the receptacle shield support portion 140 of the receptacle insulator 102. It is formed as an integrated piece and can be covered. The receptacle shield portion is formed by a deep drawing method, die casting, MIM (Metal Injection Molding) method, CNC (Computer Numerical Control) processing, MCT (Machining Center Tool) processing, or bending and forming a plate. It can be formed by doing so. The receptacle shield 150 may cover the entire inner, outer, and upper surfaces of the receptacle shield supporter 140 as one piece without any disconnected areas.

The receptacle shield 150 may be made of a metal material such as copper (Cu) or an alloy containing it, and may function to guide the plug connector 200 when combined with the plug connector 200. . That is, since the receptacle shield 150 is formed through a deep drawing method, the edges of the inner or outer surface of the receptacle shield 150 may be gently inclined. Accordingly, when the plug connector 200 is coupled, the plug connector 200 can be naturally guided on the surface of the receptacle shield 150.

In addition, in the case of the receptacle insulator 102, since it is made of a material with relatively weak strength such as plastic, there is a risk of damage due to impact applied when connecting the plug connector 200. To prevent such damage, a metal material is used. The receptacle shield 150 can be assembled to surround the edge of the receptacle insulator 102.

The side of the receptacle shield 150 includes a first receptacle shield side wall 151 and a second receptacle shield side wall 156 extending in the X direction, and a third receptacle shield side wall 153 and a fourth receptacle shield extending in the Y direction.

That is, by protecting the receptacle insulator 102 using the receptacle shield 150 made of a high-strength metal material, damage to the receptacle insulator 102 can be prevented and the strength of the receptacle connector 100 can be strengthened.

In addition, since the receptacle shield 150 surrounds the outer edge of the receptacle connector 100 as a whole without any disconnected areas, it can efficiently shield electromagnetic waves generated from the receptacle contact. When the receptacle shield 150 is mounted on a PCB board, etc., it can be grounded by being mounted on a pattern of the PCB board by soldering, etc.

Unlike general signals, the extent to which RF signal transmission transmitted by the receptacle connector 100 prevents deterioration of communication quality such as signal loss is important. EMI shielding is important because if RF signals leak to the outside, it can cause malfunctions between electronic device chips. If external noise enters the RF contact, it causes signal loss and signal errors, so it is important to prevent RF signals from leaking to the outside. Shielding is important. In addition, the RF signal shielding performance improves as the area in contact with the counterpart plug shield 250 to which the receptacle shield 150 is coupled increases, so the contact area between the receptacle shield 150 and the plug shield 250 is increased. It is important to secure and ground it.

Of course, the receptacle soldering inspection window may be formed not only around the receptacle signal contact 170 but also around the receptacle RF contact 180 and may be used to inspect the mounting state of the receptacle RF contact 180.

5 and 6 are diagrams showing the plug connector 200 of this embodiment. In the following description, it may have a length in the X-axis direction, a width in the Y-axis direction, and a height in the Z-axis direction. The plug connector 200 may include a plug insulator 202, a plug shield 250, and a plug contact 260.

The plug insulator 202 forms the outer shape of the plug connector 200 and is combined with other components of the plug connector 200 to support it. The plug insulator 202 is made of an electrically insulating material such as plastic, so that random conduction of electricity between components coupled to the plug insulator 202 can be prevented.

The plug insulator 202 is coupled to the plug shield 250, and the plug insulator 202 is partially surrounded by the plug shield 250.

The plug contact pin 260 is coupled to the plug insulator 202. The plug contacts 260 may be provided in plural numbers, and may be arranged to be spaced apart from each other and coupled to the plug insulator 202. The plug insulator 202 may support a plurality of plug contacts 260.

The plug insulator 202 may include a plug socket 210, a plug base 230, and a plug shield support portion 240.

The plug base 230 is formed to form the bottom surface of the plug insulator 202, and the plug socket 210 protrudes upward from the plug base 230.

At this time, an island receiving portion 218 into which the receptacle island 120 of the receptacle insulator 102 is inserted may be formed by being recessed in the central portion of the plug socket 210.

That is, the receptacle island 120 of the receptacle connector 100 is inserted into the island receiving portion 218 of the plug connector 200 so that the receptacle connector 100 and the plug connector 200 are electrically connected. It can be.

That is, the plug socket 210 may be formed to continuously protrude around the island receiving portion 218.

As shown in Figures 5 and 6, the plug socket 210 includes a pair of plug first socket walls 212 extending in the X direction and arranged to face each other, and plugs extending in the Y direction and arranged to face each other. A second socket wall 214 and the plug are formed between the first socket wall 212 and the plug second socket wall 214 to form the plug first socket wall 212 and the plug second socket wall 214. It may include a plurality of plug connection walls 215 that continuously connect the.

At this time, the plug connection wall 215 has an outer surface forming an inclined surface inclined at an obtuse angle with the plug first socket wall 212 and the plug second socket wall 214, and the plug first socket wall 212 ) and the second plug socket wall 214 can form a plug socket 210.

Additionally, the plug second socket wall 214 may be formed to have a shorter length than the plug first socket wall 212.

The first plug socket wall 212 may be arranged along the X direction, and the second plug socket wall 214 may be arranged along the Y direction.

Additionally, the plug connection wall 215 may include a first connection surface 215a, a second connection surface 215b, and a chamfer surface 215c.

In Figure 6, for convenience of understanding, the boundary between each of the first connection surface 215a, the second connection surface 215b, and the chamfer surface 215c and the first connection surface 215a are shown on the plug first socket wall ( 212) and the boundary with the second plug socket wall 214 are indicated by a dotted line.

The first connection surface 215a is continuously connected to the plug first socket wall 212 and may be formed to have an outer surface parallel to the outer surface of the plug first socket wall 212. Here, the outer surface may refer to a surface facing the outside of the island receiving portion 218 of the plug socket 210.

The second connection surface 215b is continuously connected to the plug second socket wall 214 and may be formed to have an outer surface parallel to the outer surface of the plug second socket wall 214.

The chamfer surface 215c is formed between the first connection surface 215a and the second connection surface 215b, and connects the first connection surface 215a and the second connection surface 215b with a straight line. , portions connected to the first connection surface 215a and the second connection surface 215b may each form an obtuse angle.

Therefore, by forming the corners of the plug socket 210 at an obtuse angle rather than a right angle, excessive stress can be prevented from being concentrated on the corners of the plug socket 210, thereby improving durability.

A plug shield support portion 240 may be formed on the outside of the plug socket 210 to couple with the plug shield 250.

The plug shield support portion 240 may be formed by extending each corner of the plug socket 210.

That is, the plug base 230 at the corner of the plug socket 210 where the first plug socket wall 212 and the second plug socket wall 214 intersect extends outward, and the plug base 230 The plug shield support portion 240 is formed to protrude at a position extending outward from the plug socket 210.

At this time, the plug shield support portions 240 at each corner may be formed continuously with each other or may be formed spaced apart from each other so that they are not continuously connected.

As described above, the plug shield support portion 240 may be coupled to the plug shield 250. In addition, a portion of the receptacle connector 100 is inserted into the plug shield 250 and the plug socket 210 coupled to the plug shield support portion 240, so that the plug connector 200 and the receptacle connector 100 are connected to each other. A receptacle receiving portion 244 that is physically coupled may be formed.

That is, the receptacle socket 110 of the receptacle connector 100 is inserted into the receptacle receiving portion 244, so that the plug connector 200 and the receptacle connector 100 are physically coupled.

Meanwhile, the plug shield 250 can be combined with the plug insulator 202 to reinforce the rigidity of the plug insulator 202. Additionally, the plug shield 250 may be coupled to a board (not shown) while being coupled to the plug insulator 202 to increase the coupling force between the plug connector 200 and the board (not shown).

The plug shield 250 may be inserted into the second plug receiving space 134 of the receptacle connector 100 when the plug connector 200 and the receptacle connector 100 are coupled.

Additionally, the plug shield 250 may be in contact with the receptacle shield 150 of the receptacle connector 100 to conduct electricity.

That is, as the plug shield 250 is inserted into the second plug receiving space 134 of the receptacle connector 100, the outer surface of the plug shield 250 and the inner surface of the receptacle shield 150 contact each other. It can be energized.

The plug shield 250 may be formed of an electrically conductive material to conduct electricity. Additionally, the plug shield 250 may be formed of a high-rigidity material. In the above embodiment, the plug shield 250 conducts electricity with the receptacle connector 100 while simultaneously increasing the rigidity of the plug insulator 202 and the coupling force between the plug connector 200 and the substrate (not shown).

The plug shield 250 can be formed by bending according to the shape of the edge of the plug insulator 202. As shown in FIG. 5, the shape of the plug shield support portion 240 of the plug insulator 202 is It can be formed integrally and cover it. The receptacle shield portion is formed by a deep drawing method, die casting, MIM (Metal Injection Molding) method, CNC (Computer Numerical Control) processing, MCT (Machining Center Tool) processing, or bending and forming a plate. It can be formed by doing so. The plug shield 250 may cover the outer and upper surfaces of the plug shield support portion 240 as one piece without any disconnected areas.

The plug shield 250 may be made of a metal material such as copper (Cu) or an alloy containing it, and may function to guide the receptacle connector 100 when combined with the receptacle connector 100. .

That is, since the plug shield 250 is formed through a deep drawing method, the edges of the inner or outer surface of the plug shield 250 can be gently inclined. Accordingly, when the receptacle connector 100 is coupled, the receptacle connector 100 can be naturally guided on the surface of the plug shield 250.

In addition, in the case of the plug insulator 202, since it is made of a material with relatively weak strength, such as plastic, there is a risk of damage due to impact applied when coupled to the receptacle connector 100. To prevent such damage, it is made of a metal material. The plug shield 250 can be assembled to surround the edge of the plug insulator 202.

The side of the plug shield 250 includes a first plug shield side wall 251 and a second plug shield side wall 252 extending in the X direction, and a third plug shield side wall 253 and a fourth plug shield extending in the Y direction. It may include a side wall 254. The plug shield first side wall 251 and the plug shield second side wall 252 are spaced apart in the Y direction and are formed parallel to each other, and the plug shield third side wall 253 and the plug shield fourth side wall 254 are They may be spaced apart in the X direction and formed parallel to each other.

Additionally, a coupling protrusion 257 may be formed on the outer surface of the plug shield 250. Additionally, the engaging protrusion 257 may be inserted into the inner surface of the receptacle shield 150, which is in contact with the outer surface of the plug shield 250, to form a coupling groove 156.

Accordingly, when the plug connector 200 and the receptacle connector 100 are coupled, the coupling protrusion 257 is inserted into the coupling groove 156 to be fixed and the coupling force can be increased.

In this embodiment, the coupling protrusion 257 is formed on the plug shield 250, and the coupling groove 156 is formed on the receptacle shield 150. However, the present invention is necessarily limited to this. It doesn't work.

For example, a coupling groove 156 may be formed on the outer surface of the plug shield 250, and a coupling protrusion 257 may be formed on the outer surface of the receptacle shield 150. Alternatively, engaging protrusions 257 that engage or engage with each other may be formed on the outer surface of the plug shield 250 and the outer surface of the receptacle shield 150.

In addition, the coupling protrusion 257 and the coupling groove 156 are in close contact with each other, so that electromagnetic interference emitted from the plug contact and the receptacle contact can be shielded.

Unlike general signals, the RF signal transmitted by the plug connector 200 is important in how much it prevents communication quality such as signal loss from being impaired. EMI shielding is important because if RF signals leak to the outside, it can cause malfunctions between electronic device chips. If external noise enters the RF contact, it causes signal loss and signal errors, so it is important to prevent RF signals from leaking to the outside. Shielding is important. In addition, the RF signal shielding performance improves as the area in contact with the counterpart receptacle shield 150 to which the plug shield 250 is coupled increases, so the contact area between the receptacle shield 150 and the plug shield 250 is increased. It is important to secure and ground it.

Meanwhile, the side surface of the plug shield 250 may include a fourth plug shield side wall 254 extending from the first plug shield side wall 251.

Additionally, engaging protrusions 257 may be formed on the first side wall 251 of the plug shield 251 to the fourth side wall 254 of the plug shield as described above. The engaging protrusion 257 may be formed along the longitudinal direction in which the first plug shield side wall 251 to the plug shield second side wall 253 extends.

As described above, when the plug connector 200 and the receptacle connector 100 are coupled, the plug shield 250 may be inserted into the second plug receiving space 134 of the receptacle connector 100.

At this time, the outer surface of the plug shield 250 is in contact with the inner surface of the receptacle shield 150. As shown in FIG. 7, the plug connector 200 is coupled to the receptacle connector 100. In the process, if the angle is slightly twisted or an inclination occurs, the plug shield second side wall 253 of the plug shield 250 may come into contact with the receptacle socket 110.

While the plug shield 250 is made of a hard metal material, the receptacle socket 110 is made of a relatively soft plastic material, so the plug shield 250 and the receptacle socket 110 are repeatedly contacted or engaged in a coupling process. If excessive force is applied, there is a risk that the receptacle socket 110, which is made of a relatively soft material, may be damaged.

Accordingly, the portions of the plug shield third side wall 253 and the plug shield fourth side wall 254 corresponding to the receptacle socket 110 are the plug shield third side wall 253 and the plug shield fourth side wall 254. A depression 255 may be formed at a lower height than the remaining portion or the first side wall 251 of the plug shield and the third side wall 252 of the plug shield 252 .

That is, a depression 255 is formed in the plug shield second side wall 253 and the plug shield fourth side wall 254, so that the plug connector 200 and the receptacle connector 100 are coupled together. Damage of the receptacle socket 110 can be prevented by preventing the plug shield third side wall 253 and the plug shield fourth side wall 254 of the shield 250 from contacting the receptacle socket 110 .

The receptacle connector 100 or the plug connector 200 is an ultra-small size product with a width of 1 cm or less, a length of 1 cm or less, and a pitch between contacts of 0.5 μm or less, so it is impossible for workers to check with the naked eye when fastening. Many city defects can occur. Therefore, when designing a connector of this ultra-small size, even the smallest details must be taken into consideration to minimize product damage.

The height of the portion of the plug shield third side wall 253 where the depression 255 is formed is the remaining portion of the plug shield third side wall 253 where the depression 255 is not formed or the first side wall of the plug shield ( 251) can be formed at a height that is 20 to 40% lower than the height of 251). Preferably, it can be formed with a height that is 30% lower.

Additionally, the width of the recessed portion 255 may be equal to or wider than the width of the receptacle socket 110 in the width direction.

Additionally, the upper end of the portion of the second side wall 253 of the plug shield 253 where the depression 255 is formed may be formed at the position where the engaging protrusion 257 of the third side wall 253 of the plug shield 253 is formed.

Meanwhile, the plug connector 200 may include a probe contact portion 259.

The probe contact portion 259 is formed to have a flat surface on the upper surface of the plug shield 250, thereby securing a space where the probe of the inspection device can be contacted during the energization test.

The size of the connector 10 is ultra-small, and the probe of the inspection device that inspects the connector 10 is also ultra-small, but it is difficult to secure a flat section that can contact the ultra-small plug shield 250 even with an ultra-small probe. , a separate space must be secured for a small-sized probe to contact the plug shield 250, and the probe contact portion 259 can secure a space for the probe of the inspection device to contact.

The probe contact portion 259 may be formed to extend a certain distance in the direction of the plug shield first side wall 251 from a corner point where the plug shield first side wall 251 and the plug shield third side wall 253 meet.

At this time, when the probe member and the receptacle connector 100 are coupled, the probe contact portion 259 is accommodated in the second plug receiving space 134, so the Y-direction length of the probe contact portion 259 is It may be formed to be shorter than the width of the second plug receiving space 134 (the distance between the inner surface of the receptacle shield 150 and the outer surface of the receptacle socket 110).

Make sure not to affect the signal contact 270. In addition, by placing plug RF contacts 280 at both ends of the connector, the plug RF contacts 280 can be spaced as much as possible to shield signal interference from each other as much as possible.
