Description

High-frequency electric connector

Technical Field

The utility model relates to a high-frequency electric connector. More particularly, the present utility model relates to an electrical connector for high frequency use that improves shielding performance against electromagnetic waves and reduces the possibility of physical breakage of terminals.

Background

Generally, in the case where substrates are connected to each other, two connectors connected to each substrate by a method such as soldering (welding) are used, and the two connectors may be connected to each other. Here, one of the two connectors is a plug connector, and the other is a receptacle connector. The receptacle connector is also referred to as a receptacle (receptacle) connector. Such a plug connector and a receptacle connector may be formed by arranging terminals in a molded part. The plug connector and the receptacle connector may be secured to each other to form an electrical connector assembly.

The coupling portion of the receptacle terminal is easily deformed by repeated coupling and uncoupling or a continuous coupling state, and such deformation adversely affects the strength of the coupling force, the durability of the connector, and the like.

When signals are transmitted and received through the connector, the structure of the connector can be changed according to the frequency of the corresponding signals. In particular, if the conventional connector is directly used for 5 th generation (5G) wireless communication, there is a case where the operation cannot be performed properly.

Detailed Description

The advantages, features, and methods of achieving the advantages and features of the present utility model will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings. However, the present utility model may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed in breadth and scope in accordance with the appended claims. Throughout the specification, the same reference numerals denote the same constituent elements.

In fig. 1a, an outer shield 10-1 (outer shield), an inner shield 10-2 (inner shield), an RF signal terminal 10-3, a signal terminal 10-4, and a housing 10-5 (molded part) of a plug connector 10 are illustrated.

The RF signal terminal 10-3 is a terminal for transmitting and receiving a high-frequency signal (for example, a frequency signal of about 50 GHz). The signal terminal 10-4 is a terminal that transmits and receives a signal having a frequency relatively lower than that of the RF signal terminal 10-3. The signal terminals 10-4 may be the following terminals: the frequency range that was processed in the existing connector before the connector corresponding to 5G is processed. The method is used for 5G wireless communication, for example, and is not necessarily limited thereto. A current of the power terminal class may also be passed to the signal terminal 10-4 as needed. As an example, the signal terminal 10-4 may include 6 PINs (PINs) that allow a current of 0.3A, and may be terminals that allow a current of, for example, 5A in excess of 0.3A to function as a power supply terminal. Of these, 6 PINs are an example.

The outer shield 10-1 serves to shield the RF signal terminal 10-3 for transmitting and receiving a high frequency signal. The inner shield 10-2 also serves to shield the RF signal terminal 10-3 for transmitting and receiving a high frequency signal.

The housing 10-5 has a base portion. The housing 10-5 has a wall portion protruding from the upper surface of the base portion, and RF signal terminals 10-3, inner shield 10-2, signal terminals 10-4, and the like are formed in the wall portion.

The housing 10-5 (molding) of the plug connector 10 is preferably of a plastic material, such as a liquid crystal polymer (Liquid Crystal Polymer, LCP). In addition, the case 10-5 may be formed of an insulator including a resin, an epoxy resin, and the like, but is not limited thereto. The RF signal terminals 10-3 and 10-4 of the plug connector 10 are preferably made of metal, for example, copper or gold plating (nickel underlayer) of copper alloy.

The outer shield 10-1 and the inner shield 10-2 may be made of a material for shielding electromagnetic waves, for example, a metal such as aluminum, a polymer composite material, a material obtained by coating or spraying a metal on plastic, a carbon material such as graphene, or the like, and may be made of the same or similar material as the RF signal terminal 10-3 and the signal terminal 10-4.

The shielding structure is specifically as follows: the "outer shield 10-1 and inner shield 10-2 of the plug connector 10" cooperate with the "outer shield 20-1 and inner shield 20-2 of the receptacle connector 20" described below to enclose the "RF signal terminal 10-3 of the plug connector 10" and the "RF signal terminal 20-3 of the receptacle connector 20" and thereby shield them.

The portion exhibiting the largest area when viewed from the bottom surface is the outer shield 10-1. A signal terminal 10-4 is disposed in the middle portion of the plug connector 10.

An inner shield 10-2 is disposed further outside than the signal terminals 10-4 (outside in the longitudinal direction (X direction) of the plug connector 10). In the longitudinal direction (X direction) of the plug connector 10, an RF signal terminal 10-3 is present between the outer shield 10-1 and the inner shield 10-2.

The receptacle connector 20 is also referred to as a receptacle connector 20.

In fig. 2a, there are illustrated an outer shield 20-1, an inner shield 20-2, RF signal terminals 20-3, signal terminals 20-4, and a housing 20-5 (molded part) of the receptacle connector 20.

The RF signal terminal 20-3 is a terminal for transmitting and receiving a high frequency signal. The signal terminal 20-4 is a terminal that transmits and receives a signal having a relatively lower frequency than the RF signal terminal 20-3. A current of the power terminal class may also be circulated to the signal terminal 20-4 as needed.

The outer shield 20-1 serves to shield the RF signal terminal 20-3 for transmitting and receiving a high-frequency signal. The inner shield 20-2 also serves to shield the RF signal terminal 20-3 for transmitting and receiving a high-frequency signal.

The housing 20-5 (molded part) of the receptacle connector 20 is preferably of a plastic material, such as LCP (Liquid Crystal Polymer). The RF signal terminals 20-3 and 20-4 of the receptacle connector 20 are preferably made of metal, for example, gold (nickel-plated) copper alloy. The outer shield 20-1 and the inner shield 20-2 may be made of a material for shielding electromagnetic waves, for example, a metal such as aluminum, a polymer composite material, a material obtained by coating or spraying a metal on plastic, a carbon material such as graphene, or the like, and may be made of the same or similar material as the RF signal terminal 20-3 and the signal terminal 20-4.

The shielding structure is specifically as follows: the "outer shield 10-1 and inner shield 10-2 of the plug connector 10" cooperate with the "outer shield 20-1 and inner shield 20-2 of the receptacle connector 20" to enclose the "RF signal terminal 10-3 of the plug connector 10" and the "RF signal terminal 20-3 of the receptacle connector 20" and thereby shield them.

The portion exhibiting the largest area when viewed from the bottom surface is the outer shield 20-1. A signal terminal 20-4 is arranged at the middle portion of the receptacle connector 20.

An inner shield 20-2 is disposed further outside than the signal terminals 20-4 (outside in the longitudinal direction (X direction) of the receptacle connector 20). In the longitudinal direction (X direction) of the receptacle connector 20, there is an RF signal terminal 20-3 between the outer shield 20-1 and the inner shield 20-2.

Fig. 3 is a further enlarged view of the plug connector 10 of fig. 1a, 1 b.

Fig. 3 (a) is a diagram showing the plug connector 10 shown in fig. 1a at other angles. The outer case 10-5 is preferably a plastic chip, not a plastic assembly, and the outer shield 10-1 is preferably a metal chip, not a metal assembly, but is not limited thereto.

Fig. 3 (b) is a view showing the case where the outer shield 10-1 and the housing 10-5 are removed in fig. 3 (a). It was confirmed that the RF signal terminal 10-3 was disposed outermost in the longitudinal direction (X direction) of the plug connector 10, the inner shield 10-2 was disposed further inside than the RF signal terminal, and the signal terminal 10-4 was disposed further inside than the RF signal terminal.

Fig. 4 (a) is a diagram showing the receptacle connector 20 shown in fig. 2a at other angles. The outer housing 20-5 is preferably a plastic piece, not a plastic assembly, and the outer shield 20-1 is preferably a metal piece, not a metal assembly, but is not limited thereto.

Fig. 4 (b) is a view showing the case where the outer shield 20-1 and the housing 20-5 are removed in fig. 4 (a). It was confirmed that the RF signal terminal 20-3 was disposed outermost in the longitudinal direction (X direction) of the receptacle connector 20, the inner shield 20-2 was disposed inside the RF signal terminal, and the signal terminal 20-4 was disposed inside the RF signal terminal. Although the inner shield 20-2 is described as being disposed further inward (in the X direction) than the RF signal terminal 20-3, it is understood from the figure that it may be overlapped in a part of the range in the X direction.

Fig. 5 shows a section along line AA in a state in which the plug connector 10 of fig. 1a, 3 is turned upside down to be fastened to the receptacle connector 20 of fig. 2a, 4.

Fig. 5 shows a case where the outer shield 10-1 of the plug connector 10 is coupled to the outer shield 20-1 of the receptacle connector 20, and also shows a case where the RF signal terminal 10-3 of the plug connector 10 is coupled to the RF signal terminal 20-3 of the receptacle connector 20.

When the cross section (i.e., YZ plane) of fig. 5 is viewed, the combination of the outer shield case 10-1 and the outer shield case 20-1 has a shape that covers the combination of the RF signal terminals 10-3 and the RF signal terminals 20-3 in the Y direction (the width direction of the connectors 10, 20).

For reference, when the outer shield case 10-1 is combined with the outer shield case 20-1, elastic deformation occurs, but such elastic deformation is omitted in fig. 5 and only the combination is conceptually shown. Likewise, when the RF signal terminal 10-3 is coupled to the RF signal terminal 20-3, elastic deformation occurs, but such elastic deformation is omitted in fig. 5 and only the coupling is conceptually shown. Therefore, there is also a case where a part of the positions where elastic deformation is required are illustrated as overlapping only.

Fig. 6 shows a section along line BB in a state in which the plug connector 10 of fig. 1a, 3 is turned upside down and fastened to the receptacle connector 20 of fig. 2a, 4.

Fig. 6 shows a case where the outer shield 10-1 of the plug connector 10 is coupled to the outer shield 20-1 of the receptacle connector 20, and a case where the signal terminal 10-4 of the plug connector 10 is coupled to the signal terminal 20-4 of the receptacle connector 20.

When the cross section (i.e., YZ plane) of fig. 6 is viewed, the combination of the outer shield case 10-1 and the outer shield case 20-1 has a shape that covers the combination of the signal terminals 10-4 and the signal terminals 20-4 in the Y direction (the width direction of the connectors 10, 20).

For reference, when the outer shield case 10-1 is bonded to the outer shield case 20-1, elastic deformation occurs, but such elastic deformation is omitted in fig. 6 and only the mutual bonding is conceptually represented. Similarly, when the signal terminal 10-4 is bonded to the signal terminal 20-4, elastic deformation occurs, but such elastic deformation is omitted in fig. 6 and only the mutual bonding is conceptually represented. Therefore, there is also a case where a part of the positions where elastic deformation is required are illustrated as overlapping only.

Fig. 7 is a bottom view of the plug connector 10 of fig. 1a and 3, with the housing 10-5 removed.

If the housing 10-5 is not present, the inner shield 10-2, the RF signal terminals 10-3, and the signal terminals 10-4 cannot be located in the home position, but fig. 7 is a view assuming that the housing 10-5 is removed and the remaining components are located in the home position. At this time, the coupling between the components (in particular, the coupling with the opposite connector, i.e., the receptacle connector 20) can be confirmed more easily.

If the housing 20-5 is not present, the inner shield 20-2, the RF signal terminals 20-3, and the signal terminals 20-4 cannot be located in the home position, but fig. 8 is a view assuming that the housing 20-5 is removed and the remaining components are located in the home position. At this time, the coupling between the members (in particular, the coupling with the plug connector 10, which is the opposite connector) can be confirmed more easily.

Fig. 9 shows the state in which the plug connector 10 and the receptacle connector 20 are fastened in a state in which the housings 10-5, 20-5 are assumed to be removed, as in fig. 7 and 8. In fig. 9, the plug connector 10 is located in the +z direction and the receptacle connector 20 is located in the-Z direction.

As can be seen from fig. 9, the RF signal terminal 10-3 of the plug connector 10 and the RF signal terminal 20-3 of the receptacle connector 20 are coupled (fastened) to each other. The inner shield 10-2 and the inner shield 20-2 are coupled to each other, and the outer shield 10-1 and the outer shield 20-1 are coupled to each other.

It is also known that the "combination of RF signal terminal 10-3 and RF signal terminal 20-3" is located between the "combination of outer shield 10-1 and outer shield 20-1" and the "combination of inner shield 10-2 and inner shield 20-2" in the longitudinal direction (X direction) of

connectors

10, 20.

It is also known that the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" is located between the "combination of the outer shield 10-1 and the outer shield 20-1" in the width direction (Y direction) of the

connectors

10, 20. It is also known that at least a part of the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" is located between the "combination of the inner shield 10-2 and the inner shield 20-2" in the width direction (Y direction) of the

connectors

10, 20.

According to this structure, the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" can be electrically shielded (electromagnetic wave shielded) by the "combination of the outer shield 10-1 and the outer shield 20-1" and the "combination of the inner shield 10-2 and the inner shield 20-2".

Fig. 10 is a view showing a CC section of fig. 9.

As is clear from the CC section of fig. 10, the outer shield 10-1 (plug outer shield) of the plug connector 10 is brought into contact with the outer shield 20-1 (jack outer shield) of the jack connector 20 and the inner shield 20-2 (jack inner shield) of the jack connector 20 by the insertion (fitting) fastening. Thus, the components 20-1, 10-1, 20-2 are electrically connected. The inner shield 20-2 of the receptacle connector is also in contact with the inner shield 10-1 of the plug connector. However, as shown in fig. 10, 7, etc., the inside end 10-2IE of the inside shield 10-2 of the plug connector is not in contact with each other.

For example, one of the main configurations for well shielding the RF signal terminals 10-3, 20-3 is configured such that the outer shield 10-1 of the plug connector electrically connects the outer shield 20-1 of the receptacle connector to the inner shield 20-2 of the receptacle connector like a bridge.

In addition, the structure in which the outer shields 10-1, 20-1 are coupled to the inner shields 10-2, 20-2 surrounds the RF signal terminals 10-3, 20-3 in the longitudinal and width directions of the

connectors

10, 20 as a whole.

In the example of the drawings, the outer shield 10-1 of the plug connector electrically connects the outer shield 20-1 of the receptacle connector with the inner shield 20-2 of the receptacle connector, but this is an example, and in general, the outer shield of the electrical connector may electrically connect the outer shield of the opposite connector with the inner shield. If the electrical connector is a plug connector 10, the opposite connector is a receptacle connector 20, in contrast to the plug connector 10 if the electrical connector is a receptacle connector 20.

In addition, in the example of the drawings, the outer shield 10-1 of the plug connector is one piece, and the outer shield 20-1 of the receptacle connector is also one piece. However, the outer shield 10-1 or the bridge-like 20-1 may be arranged so as to cover the 4 surfaces of the connector 10 or the connector 20, and may be one piece as in the drawings, but may be a plurality of pieces (for example, two pieces).

As shown in fig. 7 and 9, the inner shield 10-2 is present between the RF signal terminal 10-3 and the signal terminal 10-4 in the longitudinal direction (X direction) of the plug connector 10. Of course, there may be sections slightly overlapping in the longitudinal direction, if necessary. The RF signal terminals 10-3, 20-3 are better covered when overlapped, so the electromagnetic wave shielding effect is large.

As shown in fig. 8 and 9, the inner shield 20-2 is located between the RF signal terminal 20-3 and the signal terminal 20-4 in the longitudinal direction (X direction) of the receptacle connector 20. Of course, as shown in the figure, there may be a slight overlap in the longitudinal direction (for example, the RF signal terminal 20-3 overlaps with a part of the section of the inner shield 20-2 in the longitudinal direction (X direction)).

In other words, the inner shields 10-2, 20-2 may also be disposed on both sides in the longitudinal direction (X direction) of the signal terminals 10-4, 20-4.

On the other hand, the mounting portions 10-1M, 10-2MI, 10-2MO, 20-1M, 20-2MO, 20-2MI are shown in FIG. 10. The mounting portion is a portion where each of the components 10-1, 10-2 of the plug connector 10 is mounted (e.g., soldered, etc.) to a substrate, and is a portion where each of the components 20-1, 20-2 of the receptacle connector 20 is mounted to a substrate (another substrate).

Specifically, the outer shield 10-1 (first outer shield, for example) has a mounting portion 10-1M for a substrate below the height direction of the plug connector 10 (electrical connector, for example) in the-Z direction in fig. 3 and 7, and in the +z direction in fig. 10 where the plug connector 10 is turned upside down and coupled, and has a bent portion extending from the mounting portion 10-1M to the upper side of the height direction of the plug connector 10 (electrical connector, for example) in the +z direction in fig. 3 and 7, and in the-Z direction in fig. 10 where the plug connector 10 is turned upside down and coupled, at least a part of the bent portion contacts at least a part of the outer shield 20-1 of the receptacle connector 20 (for example, opposite connector) when the plug connector 10 (for example) is inserted into the receptacle connector 20 (for example).

As described above, if the plug connector is referred to as an electrical connector, the receptacle connector is an opposing connector. Of course, without being limited thereto, if the jack connector is referred to as an electrical connector, the plug connector is an opposing connector.

The inner shield 10-2 (e.g., first inner shield) of the plug connector 10 has a mounting portion 10-2MO (e.g., first mounting portion) for a substrate below the height direction of the plug connector 10 (e.g., electrical connector) (in fig. 3 and 7, in the +z direction in fig. 10 to be combined by turning up and down the plug connector 10), has a bending portion extending from the mounting portion 10-2MO to the upper side of the height direction of the plug connector (e.g., electrical connector) (in fig. 3 and 7, in the +z direction in fig. 10 to be combined by turning up and down the plug connector 10), and has a mounting portion 10-2MI (e.g., second mounting portion) for a substrate extending from the bending portion to the lower side of the height direction of the plug connector 10 (e.g., electrical connector) (in fig. 3 and 7, in the +z direction in fig. 10 to be combined by turning up and down the plug connector 10).

Also here, as described above, if the plug connector is referred to as an electrical connector, the receptacle connector is an opposing connector. Of course, without being limited thereto, if the jack connector is referred to as an electrical connector, the plug connector is an opposing connector.

Fig. 11 is a view showing an AA cross section of fig. 4 (a).

In the receptacle connector 20, the uppermost end of the inner shield 20-2 has a height higher than that of the uppermost end of the RF signal terminal 20-3. In fig. 11, the height direction indicates the Z direction, the upper side of the height direction is the +z direction, and the lower side of the height direction indicates the-Z direction.

According to this structure, even if an external force (pressurizing force) is applied when the plug connector 10 is coupled to the receptacle connector 20, most of the force is received by the inner shield case 20-2, and the pressurizing force is not transmitted to the RF signal terminal 20-3, so that the RF signal terminal 20-3 is prevented from being broken.

That is, the inner shield 20-2 not only functions to shield electromagnetic waves from the RF signal terminal 20-3, but also protects the RF signal terminal 20-3 from physical forces.

While fig. 11 only illustrates the receptacle connector 20, it is apparent from fig. 3 that the height of the uppermost end of the inner shield 10-2 is also higher than the height of the uppermost end of the RF signal terminal 10-3 in the receptacle connector. In fig. 4, the height direction indicates the Z direction, the upper side of the height direction is the +z direction, and the lower side of the height direction indicates the-Z direction.

According to this structure, even if an external force (pressurizing force) is applied when the plug connector 10 is coupled to the receptacle connector 20, most of the force is received by the inner shield case 10-2, and the pressurizing force is not transmitted to the RF signal terminal 10-3, so that the RF signal terminal 10-3 is prevented from being broken.

That is, the inner shield 10-2 not only functions to shield electromagnetic waves from the RF signal terminal 10-3, but also protects the RF signal terminal 10-3 from physical forces.

More precisely, the combination of the inner shield 10-2 and the inner shield 20-2 not only functions to shield electromagnetic waves from the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3, but also protects the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3 from physical forces.

3 holes 10-H1, 10-H2, and 10-H3 are shown, and these holes are structures for impedance matching, and are described in detail in FIGS. 13 and 14.

Fig. 14 is also a diagram showing a state in which the plug connector 10 is inserted in a downward (-Z direction) direction and the receptacle connector 20 is inserted in an upward (+z direction) direction, in which the viewing direction is slightly different from that of fig. 13.

First, the first hole 10-H1 is the following hole: in the width direction (Y direction) of the plug connector 10, a portion of the housing 10-5 is formed between two contact points formed by the contact of the RF signal terminal 10-3 of the plug connector 10 with the RF signal terminal 20-3 of the receptacle connector 20. The first hole 10-H1 is used for impedance matching.

In addition, the second hole 10-H2 and the third hole 10-H3 are the following holes: portions of the housing 10-5 that are respectively formed below two contact points formed by the contact of the RF signal terminal 10-3 of the plug connector 10 with the RF signal terminal 20-3 of the receptacle connector 20 in the fitting direction (height direction, Z direction) of the plug connector 10 and the receptacle connector 20. The holes 10-H2, 10-H3 are also used to achieve impedance matching.

For example, when signals of about 50GHz are transmitted and received through the RF signal terminals 10-3, 20-3, if these holes 10-H1, 10-H2, 10-H3 are not provided, reflection loss occurs when a circuit of a signal source and a load is connected. If the reflection loss is reduced by appropriately selecting the positions of the holes, the sensitivity (for example, the signal-to-noise ratio, the linearization of the frequency characteristics, and the like) can be improved when the component is operated.

The positions of the second holes 10-H2 and the third holes 10-H3 shown in FIG. 14 are preferred examples, but are not necessarily limited thereto. The preferred position is a position for reducing reflection loss, and thus can be changed appropriately to match impedance according to the condition of each element. For example, in FIG. 14, only the second hole 10-H2 may be present and the third hole 10-H3 may not be present. Alternatively, in FIG. 14, only the third hole 10-H3 may be present and the second hole 10-H2 may not be present. In fig. 13 and 14, only one side in the longitudinal direction of the connector is shown, but as shown in fig. 1a, the RF signal terminal 10-3 is provided on one side in the longitudinal direction of the plug connector 10 (for example, in the-X direction, the left side in fig. 1 a), the other RF signal terminal 10-3 is provided on the other side in the longitudinal direction of the plug connector 10 (for example, in the +x direction, the right side in fig. 1 a), but only one hole (one of the second hole and the third hole) is provided in the case 10-5 on the bottom surface near the left RF signal terminal 10-3, and two holes are provided in the case 10-5 on the bottom surface near the right RF signal terminal 10-3. Conversely, only one hole (one of the second hole and the third hole) may be provided in the bottom surface of the case 10-5 near the RF signal terminal 10-3 on the right side, and two holes may be provided in the bottom surface of the case 10-5 near the RF signal terminal 10-3 on the left side. Only one hole (one of the second hole and the third hole) may be provided in the bottom surface of the case 10-5 near the left RF signal terminal 10-3, and only one hole (one of the second hole and the third hole) may be provided in the bottom surface of the case 10-5 near the right RF signal terminal 10-3. In this case, the holes may be arranged in a point-symmetrical manner with respect to the center of the plug connector 10, or may be arranged in a point-symmetrical manner with respect to the center line in the longitudinal direction or the width direction. Such a configuration may be any combination capable of achieving impedance matching. In accordance with an exemplary example shown in fig. 13, 14, etc., the second hole 10-H2 and the third hole 10-H3 are also provided in the case 10-5 on the bottom surface near the RF signal terminal 10-3 on the left side (in fig. 1 a), and the second hole 10-H2 and the third hole 10-H3 are also provided in the case 10-5 on the bottom surface near the RF signal terminal 10-3 on the right side.

Referring to fig. 13 and 14, the jack connector 20 of fig. 4 is in a coupled state, or in a state in which it is present alone, the inner shield 20-2 covers at least a part of the RF signal terminals 20-3 on both sides in the width direction (Y direction) of the jack connector 20. This not only plays a role of shielding electromagnetic waves from the RF signal terminals 20-3, 10-3, but also plays a role of preventing physical breakage of the RF signal terminals 20-3, 10-3.

In general, this can be described as follows: the inner shield 10-2 or 20-2 covers at least a portion of the outer side of the RF signal terminal 10-3 or 20-3 on both sides in the width direction of the

electrical connector

10 or 20. Of course, in fig. 4 of the embodiment, the RF signal terminal 20-3 of the receptacle connector 20 is surrounded by the inner shield 20-2 in the width direction, and in fig. 3, the RF signal terminal 10-3 of the plug connector 10 is not surrounded by the inner shield 10-2 in the width direction, but this is merely an example.

That is, the following configuration may be adopted in contrast to fig. 3 and 4: the RF signal terminals 20-3 of the receptacle connector 20 are not surrounded by the inner shield 20-2 in the width direction, and the RF signal terminals 10-3 of the plug connector 10 are surrounded by the inner shield 10-2 in the width direction. Alternatively, the following forms are also possible: the RF signal terminals 20-3 of the receptacle connector 20 are surrounded by the inner shield 20-2 in the width direction, and the RF signal terminals 10-3 of the plug connector 10 are also surrounded by the inner shield 10-2 in the width direction.
