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 signals, which has improved electromagnetic wave shielding performance, reduced interference or noise in the longitudinal/width directions between the terminals of the high frequency signals, reduced connector width, and reduced possibility of physical breakage of the 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.

The shield plates 10-1a-E are effectively inserted with the shield plates 20-1-E to shield signal interference or noise between the RF signal terminals adjacent in the width direction.

The shield plates 10-1a-E are effectively inserted into the shield plates 20-1-E to shield 4 surfaces of the RF signal terminals 10-3, 20-3, thereby shielding signal interference or noise between the RF signal terminals adjacent in the longitudinal and width directions, and also shielding signal interference or noise from other sources (e.g., the signal terminals 10-4, 20-4) in addition thereto.

The mounting portion 20-4-M2 of the signal terminal 20-4 is located between the mounting portion 20-1-M of the shield case 20-1 and the mounting portion 20-3-M of the RF signal terminal 20-3 in the width direction, so that the isolation (isolation) between the RF signal terminals 20-3 adjacent in the length direction is improved. Not only is the connector 20, but the connector 10 is also the same.

The RF signal terminals 10-3, 20-3 have a structure having a longitudinal direction extending portion and a width direction extending portion (that is,

A letter structure), not only can the size of the connector be reduced (in particular, the width direction size) but also stable coupling and more excellent frequency performance can be achieved, as compared with the in-line structure.

The "shield case 10-1 of the plug connector 10" and the "shield case 20-1 of the receptacle connector 20" cooperate 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", thereby shielding electromagnetic waves.

10, 20.

The combination of the shield case 10-1 and the shield case 20-1 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.

The effects of the present utility model are not limited to those exemplified above, and the present specification also includes further effects.

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, a shield 10-1 of a plug connector 10, RF signal terminals 10-3, signal terminals 10-4, and a housing (molded part) 10-5 are illustrated. The shield 10-1 may have a different shape from the shield 10-1a or the shield 10-1b on the opposite side thereof, but is not limited thereto. The main difference between the shield 10-1a and the shield 10-1b in the shield 10-1 is the presence or absence of the protruding portion (also referred to as "shield plate") 10-1a-E. That is, as an example, as shown in fig. 1a, the shield case 10-1a has a protruding portion (shield plate) 10-1a-E formed by bending approximately 90 degrees from the main body of the shield case, and the shield case 10-1b does not have the protruding portion 10-1a-E. As described below, the shield plates 10-1a-E as the protruding portions are inserted between protruding portions (shield plates 20-1-E) of the shield case 20-1 of the opposite connector, i.e., the receptacle connector 20.

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. To distinguish from the RF signal terminal 10-3, the signal terminal 10-4 may also be referred to as a normal signal terminal as needed. Of these, it is preferable to transmit a high-frequency signal to the RF signal terminal 10-3, but it is not completely excluded to transmit a high-frequency signal to the normal signal terminal 10-4. 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 shield case 10-1 (10-1 a and/or 10-1 b) 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 (molding) 10-5 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 shield case 10-1 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 Dan Heixi, 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 "shield case 10-1 of the plug connector 10" encloses the "RF signal terminal 10-3 of the plug connector 10" and the "RF signal terminal 20-3 of the receptacle connector 20" in cooperation with the "shield case 20-1 of the receptacle connector 20" described below, thereby shielding.

When viewed from the bottom, a part of the shield case 10-1 is disposed. The signal terminal 10-4 is disposed at a longitudinal middle portion of the plug connector 10.

The shield case 10-1 is disposed further outside than the signal terminals 10-4 (outside in the longitudinal direction (X direction) of the connector 10). The RF signal terminal 10-3 is present at a portion overlapping the shield case 10-1 in the longitudinal direction (X direction) of the connector 10.

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

In fig. 2a, a shield 20-1 of a receptacle connector 20, RF signal terminals 20-3, signal terminals 20-4, and a housing (molding) 20-5 are illustrated.

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 passed to the signal terminal 20-4 as needed.

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

The housing (molding) 20-5 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 shield case 20-1 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 Dan Heixi, 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 "shield case 10-1 of the plug connector 10" and the "shield case 20-1 of the receptacle connector 20" cooperate 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", thereby shielding.

When viewed from the bottom, a portion of the shield 20-1 is observed. The signal terminals 20-4 are arranged at the middle portion in the longitudinal direction of the receptacle connector 20.

The shield case 20-1 is disposed further outside than the signal terminals 20-4 (outside in the longitudinal direction (X direction) of the connector 20). Unlike the case where the plug connector 10 includes a shield 10-1 having a different shape (that is, having a longer extending portion extending from the outside toward the inside in the longitudinal direction) like the symbols 10-1a and 10-1b in the drawings, the shield 20-1 has the same shape (the shape may be a shape that is line-symmetrical in the longitudinal direction or the width direction) in the receptacle connector 20.

The RF signal terminal 20-3 is present at a portion overlapping the shield case 20-1 in the longitudinal direction (X direction) of the connector 20.

For reference, in fig. 1a, 1b, 2a, 2b, a direction (X, Y, Z) is arbitrarily set, but this direction is not maintained when the

connectors

10, 20 are coupled to each other, and when coupling the plug connector 10 to the receptacle connector 20, it is necessary to invert one of the connectors up and down and then couple it.

The housing 10-5 (not shown) is preferably a plastic chip, not a plastic assembly, and the shield 10-1 is preferably a metal chip, not a metal assembly, but is not limited thereto. In fig. 1a, 3, 4 shields 10-1 (two 10-1a and two 10-1 b) are shown.

From fig. 3, it can be confirmed that the shield 10-1 is disposed on the outermost side in the longitudinal direction (X direction) of the connector 10, the RF signal terminal 10-3 is disposed on the inner side than the shield and at a position overlapping the shield 10-1 in the longitudinal direction, and the signal terminal 10-4 is disposed on the inner side than the shield 10-1. When the center point in the longitudinal direction and the width direction of the connector 10 is taken as a reference, each component has a substantially point-symmetrical structure. For example, as can be seen from fig. 3, the shield case 10-1a at the lower left end and the shield case 10-1a at the upper right end are in a point-symmetrical shape. As can be seen from fig. 3, the shield case 10-1b located at the upper left end and the shield case 10-1b located at the lower right end are formed in a point-symmetrical shape.

The RF signal terminal 10-3 includes mounting portions 10-3-M for a substrate and contact portions 10-3-C for the opposing connector 20 at both ends thereof. The contact portion 10-3-C may be a fixed end, but is not limited thereto.

In fig. 3, approximately 3 faces of the RF signal terminal 10-3 are surrounded by the shield 10-1.

In fig. 4, the housing 20-5 (not shown) is preferably a plastic chip, not a plastic assembly, and the shield 20-1 is preferably a metal chip, not a metal assembly, but is not limited thereto. In fig. 2a, 4 shields 20-1 are shown.

It was confirmed that the shield case 20-1 was disposed outermost in the longitudinal direction (X direction) of the connector 20, the RF signal terminal 20-3 was disposed at a position overlapping the shield case 20-1 in the longitudinal direction, and the signal terminal 20-4 was disposed further inside than the shield case 20-1.

In addition, the shield plates 10-1a-E of the shield case 10-1a as an example shown in FIG. 1a are interposed between the shield plates 20-1-E of the shield case 20-1 as an example shown in FIG. 5. The shielding plates 20-1-E have, for example, two electrical contacts C1, C2, so as to be in electrical contact with the shielding plates 10-1a-E. More specifically, as described below, the shield plates 10-1a-E are inserted between the shield plate 20-1-E of one shield case 20-1 (e.g., the shield case at the left lower end in fig. 4) and the shield plate 20-1-E of the other shield case 20-1 (e.g., the shield case at the left upper end in fig. 4), between the contact C1 of the shield case 20-1 at the left lower end and the contact C1 of the shield case 20-1 at the left upper end, and between the contact C2 of the shield case 20-1 at the left lower end and the contact C2 of the shield case 20-1 at the left upper end, the shield plates 10-1a-E are inserted, thereby being engaged with each other.

The RF signal terminal 20-3 includes mounting portions 20-3-M for the substrate and contact portions 20-3-C for the opposing connector 10 at both ends thereof. The contact portion 20-3-C is preferably a free end, but is not limited thereto.

In fig. 4, approximately 3 faces of the RF signal terminal 20-3 are surrounded by the shield 20-1. In fig. 4, approximately 4 faces are seen to be surrounded according to the viewing angle, but it is understood that they are not completely surrounded.

Fig. 5 is a cross-sectional AA view of a case of combining the plug connector 10 of fig. 1a with the receptacle connector 20 of fig. 2 a.

Specifically, fig. 5 is an AA cross-sectional view of the plug connector 10 of fig. 1a turned upside down to be coupled to the receptacle connector 20 of fig. 2 a. That is, as can be seen from fig. 5, the direction X, Y, Z is the same as the direction X, Y, Z of fig. 2a for the receptacle connector 20, and the Z direction of fig. 1a is changed to-Z direction (due to the upside down) for the plug connector 10.

For reference, when the RF signal terminal 20-3 is combined with the RF signal terminal 10-3, the upper portion of the RF signal terminal 20-3 of fig. 5 is slightly bent inward, but in fig. 5, such bending is omitted for convenience of illustration.

Fig. 6 is a BB cross-sectional view of a case where the plug connector 10 of fig. 1a is combined with the receptacle connector 20 of fig. 2 a.

Specifically, fig. 6 is a BB cross-sectional view of the plug connector 10 of fig. 1a turned upside down to be coupled to the receptacle connector 20 of fig. 2 a. That is, as can be seen from fig. 6, the direction X, Y, Z is the same as the direction X, Y, Z of fig. 2a for the receptacle connector 20, and the Z direction of fig. 1a is changed to-Z direction (due to the upside down) for the plug connector 10.

For reference, when the signal terminal 20-4 is combined with the signal terminal 10-4, the upper portion of the signal terminal 20-4 of fig. 6 is slightly bent inward, but in fig. 6, such bending is omitted for convenience of illustration.

Fig. 7 is a CC section view of the case of combining the plug connector 10 of fig. 1a with the receptacle connector 20 of fig. 2 a.

Specifically, fig. 7 is a CC cross-sectional view of the plug connector 10 of fig. 1a turned upside down to be coupled to the receptacle connector 20 of fig. 2 a. That is, as can be seen from fig. 7, the direction X, Y, Z is the same as the direction X, Y, Z of fig. 2a for the receptacle connector 20, and the Z direction of fig. 1a is changed to-Z direction (due to the upside down) for the plug connector 10.

The shield plates 10-1a-E of the shield case 10-1a are interposed between the shield plates 20-1-E of the shield case 20-1. The shielding plates 20-1-E have, for example, two electrical contacts C1, C2 and are thus in electrical contact with the shielding plates 10-1a-E. More specifically, the shield plates 10-1a-E are inserted between the shield plate 20-1-E of one shield case 20-1 (e.g., the shield case at the left lower end in fig. 4) and the shield plate 20-1-E of the other shield case 20-1 (e.g., the shield case at the left upper end in fig. 4), between the contact C1 of the shield case 20-1 at the left lower end and the contact C1 of the shield case 20-1 at the left upper end, and between the contact C2 of the shield case 20-1 at the left lower end and the contact C2 of the shield case 20-1 at the left upper end, the shield plates 10-1a-E are inserted, thereby being engaged with each other. In fig. 7, a cross section of the following is illustrated: the shield plates 10-1a to E are inserted between the contact C2 of one shield case 20-1 and the contact C2 of the other shield case 20-1 to be joined to each other.

Fig. 8 is a view assuming that the housings 10-5, 20-5 are removed in the coupled state of fig. 5 to 7, respectively.

Fig. 8 is a top view of the plug connector 10 shown in fig. 3, which is obtained by removing the housings 10-5, 20-5 in the coupled state of fig. 5 to 7, respectively, and is also considered to be coupled to the receptacle connector 20 shown in fig. 4 by turning the plug connector 10 upside down.

As shown in fig. 8, the RF signal terminal 10-3 is combined with the RF signal terminal 20-3. The shield case 20-1 is coupled to the shield case 10-1 to cover the "coupled body of the RF signal terminal 10-3 and the RF signal terminal 20-3" in a surrounding manner.

In particular, in fig. 8, the shield plates 10-1a to E and the shield plates 20-1 to E are present between the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" at the upper left end and the "combination of the RF signal terminal 10-3 and the RF signal terminal 20-3" at the lower left end, and therefore the shielding effect therebetween can be further improved.

On the other hand, as is clear from fig. 8 in which the connector 10 is coupled to the connector 20, approximately 4 surfaces of the "coupling body of the RF signal terminal 10-3 and the RF signal terminal 20-3" are surrounded by the "coupling body of the shield case 10-1 and the shield case 20-1". With this structure, the electric signals of the RF signal terminals 10-3, 20-3 can be shielded efficiently.

In contrast to fig. 8, approximately 3 faces of the RF signal terminal 10-3 are surrounded by the shield case 10-1 in fig. 3, and approximately 3 faces (or 4 faces slightly opened) of the RF signal terminal 20-3 are surrounded by the shield case 20-1 in fig. 4. That is, fig. 3 and 4 show the

connectors

10 and 20 before being coupled, and fig. 8 shows the

connectors

10 and 20 after being coupled.

As shown in fig. 9, the shield plates 10-1a-E of the shield case 10-1a are interposed between the shield plates 20-1-E of the two shield cases 20-1. At the time of insertion, the shield plates 10-1a-E are engaged between the two opposing contacts C1, and further, the other portion of the shield plates 10-1a-E is engaged between the two opposing contacts C2. With this structure, the fastening between the shields can be easily and firmly achieved, and the shielding effect between the adjacent RF signal terminals can be also exhibited.

As shown in the right side of fig. 9, a joint body (large square block) of the RF signal terminal exists between the shield contact portion (small square block on the left) and the other shield contact portion (small square block on the right) in the X direction, which is the longitudinal direction of the connector.

For example, if the RF signal terminal 20-3 arranged at the lower right end in fig. 4 is enlarged, as in fig. 10.

In fig. 10, in order to reduce the overall size of the connector 20, the contact portions 20-3-C are arranged in the RF signal terminal 20-3 in a direction 90 degrees with respect to the mounting portion 20-3-M.

As is clear from fig. 10, the contact portion 20-3-C of the RF signal terminal 20-3 may be formed in the width direction (Y direction), but is not limited thereto. As is clear from fig. 9, the contact portion of the RF signal terminal 20-3 is coupled to the contact portion of the RF signal terminal 10-3 formed in the width direction as well.

The contact portion 20-3-C shown in FIG. 10 is an elastic portion and is a free end. On the other hand, the opposite portion that is coupled to the contact portion 20-3-C of the RF signal terminal 20-3 of the receptacle connector 20 (i.e., the contact portion 10-3-C of the RF signal terminal 10-3 of the plug connector 10) may not be a free end, but is not limited thereto.

For reference, in fig. 10, the mounting portion 20-3-M is located in the-Y direction and the contact portion 20-3-C is located in the-X direction, however, if the mounting portion 20-3-M is located in the-Y direction and the contact portion 20-3-C is located in the +y direction (i.e., if the RF signal terminals 10-3, 20-3 are in a straight configuration, not

Word or->

A zigzag structure), the overall width of the connector 20 becomes large.

In addition, as shown in FIG. 10, the structure in which the mounting portion 20-3-M is 90 degrees from the contact portion 20-3-C further improves the high frequency performance. That is, the RF signal terminal 20-3 of the structure of FIG. 10 can cope with higher frequencies than the structure (i.e., the in-line structure) in which the mounting portion 20-3-M is located in the-Y direction and the contact portion 20-3-C is located in the +Y direction.

In fig. 11, the portions indicated by 5 small squares are mounting portions for a substrate. Fig. 11 is a top view of the receptacle connector 20, assuming that the housing 20-5 is removed, the mounting portion may be fixed to a substrate (not shown) located therebelow by soldering or the like.

At this time, in the width direction, a mounting portion (also referred to as "inner mounting portion") 20-4-M2 of the signal terminal 20-4 is arranged between a mounting portion (also referred to as "RF mounting portion") 20-3-M of the RF signal terminal 20-3 and a mounting portion (also referred to as "shield mounting portion") 20-1-M of the shield case 20-1. If configured in this way, the isolation (isolation) between the RF signal terminals 20-3 in the length direction is improved, so that signal interference, noise between the RF terminals, or the like is reduced. In addition, resonance between RF terminals is also reduced.

That is, in the example of fig. 11, the isolation between the RF signal terminal 20-3 at the lower left end and the RF signal terminal 20-3 at the lower right end is improved. Likewise, the isolation of the RF signal terminal 20-3 at the upper left end from the RF signal terminal 20-3 at the upper right end increases.

The inner mounting portion 20-4-M2 is exposed to the bottom surface and is fixed to a substrate (not shown). This exposed state can also be confirmed in fig. 2b and 6.

In addition, the signal terminal 20-4 has another mounting portion (also referred to as "front end mounting portion") 20-4-M1 on the outside. Similarly, the exposed state can be confirmed in fig. 2b and 6.

Fig. 12 is a plug connector showing other embodiments.

As can be seen from fig. 12, the plug connector 10 'may also have more (e.g., 8) RF signal terminals 10-3' than the RF signal terminals in fig. 1 a. In the example of fig. 12, the number of RF signal terminals 10-3' is 8, and a normal signal terminal (e.g., signal terminal 10-4 in fig. 1a, etc.) is not present, but is not limited thereto. However, the distinction between the RF signal terminal and the normal signal terminal is not absolute, and the "RF signal terminal" means that the RF signal terminal is suitable for transmitting and receiving a high frequency signal, but does not mean that a signal of a lower frequency cannot be transmitted and received, and thus the plug connector 10 of fig. 1a can also sufficiently operate in the configuration of fig. 12 (the number difference of the signal terminals 10-4 is not discussed). In fig. 12, the number of the shields 10-1' is 4, and is divided into two types. Namely, it is divided into two shields 10-1a ' having shielding plates 10-1a ' -E and two shields 10-1b ' having no shielding plates. This is also the case as described in fig. 1 a.

Fig. 13 is a diagram showing a receptacle connector of another embodiment.

The receptacle connector (jack connector) 20 'of fig. 13 is combined with the plug connector 10' of fig. 12.

If the connectors 10', 20' are coupled, the shields 10-1', 20-1', and the metal pieces 20-11, 20-12 are coupled to each other. At this time, in the examples of fig. 12, 13, 8 shielding blocks are formed, whereby 8 "the combination of the RF signal terminals 10-3 'and the RF signal terminals 20-3' are electrically shielded with respect to each other, respectively. In fig. 13, 6 pieces of metal 20-11, 20-12 are illustrated, which may be part of the shield 20-1' or may be separate entities. The number of shielding blocks, whether part or separate, is likewise 8 when connector 10 'is combined with connector 20'. For example, it is known that shield 10-1' connects shield 20-1' to metal piece 20-11, and that shield 20-1' connects metal piece 20-12.

For example, in the claims of this application, the first signal terminal is denoted by symbol 10-3 in FIG. 1a, the second signal terminal is denoted by symbol 10-4 in FIG. 1a, or the first signal terminal is denoted by the left and right two of the 8 symbols 10-3 'in FIG. 12, and the second signal terminal is denoted by the middle 4 of the 8 symbols 10-3' in FIG. 12.

Of course, in the claims of this application, the first signal terminal is denoted by symbol 20-3 in fig. 2a, the second signal terminal is denoted by symbol 20-4 in fig. 2a, or the first signal terminal is denoted by left and right two of the 8 symbols 20-3 'of fig. 13, and the second signal terminal is denoted by middle 4 of the 8 symbols 20-3' of fig. 13.
