[ effects of utility model ]
According to the embodiment of the technical idea of the present invention, at least the following effects are obtained.
The shield plates 10-1a-E and the shield plates 20-1-E are efficiently inserted to shield signal interference or noise between the RF signal terminals adjacent in the width direction.
The shielding plates 10-1a-E and the shielding plates 20-1-E are efficiently inserted and combined to shield 4 surfaces of the RF signal terminals 10-3 and 20-3, thereby shielding signal interference and noise between adjacent RF signal terminals in the longitudinal direction and the width direction, and also shielding signal interference and noise from other sources (for example, the signal terminals 10-4 and 20-4).

Detailed Description
The advantages, features, and methods of attaining the above-described advantages and features of the invention will become apparent from the following detailed description of illustrative embodiments of the invention when considered in conjunction with the accompanying drawings. However, the present invention can be realized in various forms, and is not limited to the embodiments disclosed below, and the present embodiment is only provided to completely disclose the present invention and completely inform the scope of the present invention to a person having ordinary skill in the art to which the present invention belongs, and the present invention is defined only in accordance with the scope of the claims. Throughout the specification, the same reference numerals denote the same constituent elements.
Fig. 1a is a diagram showing a plug connector 10 according to the present invention.
In fig. 1a, a shield case 10-1, an RF signal terminal 10-3, a signal terminal 10-4, and a housing (molded portion) 10-5 of the plug connector 10 are illustrated. Also, the shield can 10-1 may be shaped differently like the shield can 10-1a or the shield can 10-1b on the opposite side thereof, but is not limited thereto. The main difference between the shield can 10-1a and the shield can 10-1b in the shield can 10-1 is the presence or absence of the projections (also referred to as "shield plates") 10-1 a-E. That is, as an example, as shown in fig. 1a, the shield case 10-1a has a projection (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 projection 10-1 a-E. As described below, the shield plate 10-1a-E as the projection is inserted between the projections (shield plates 20-1-E) of the shield shell 20-1 of the opposing 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 of a relatively lower frequency than the RF signal terminal 10-3. The signal terminal 10-4 may also be referred to as a normal signal terminal as necessary in order to be distinguished from the RF signal terminal 10-3. Among them, it is preferable to transmit a high frequency signal to the RF signal terminal 10-3, but it is not entirely excluded to transmit a high frequency signal to the normal signal terminal 10-4. The signal terminal 10-4 may be the following terminal: the frequency range that was processed in the existing connector before the connector corresponding to 5G is processed. The use in 5G wireless communication is an example, but not necessarily limited thereto. A current at the level of the power supply terminal may also be passed to the signal terminal 10-4 as desired. As an example, the signal terminal 10-4 may include 6 PINs (PINs) that allow a current of 0.3A, and may be a terminal that allows a current exceeding 0.3A to, for example, 5A to function as a power supply terminal. Of these, 6 PINs are an example.
The shield case 10-1(10-1a and/or 10-1b) functions to shield the RF signal terminal 10-3 that transmits and receives high-frequency signals.
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 the wall portion is formed with an RF signal terminal 10-3, an inner shield case 10-2, a signal terminal 10-4, and the like.
The housing (molded portion) 10-5 of the plug connector 10 is preferably made of a plastic material, and may be, for example, Liquid Crystal Polymer (LCP). In addition, the housing 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 the signal terminals 10-4 of the plug connector 10 are preferably made of a metal material, such as copper, or a material obtained by plating a copper alloy with gold (nickel plating), but not limited thereto.
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 a plastic, a carbon material such as graphene, or the like, or may be made of a material similar to or the same as the RF signal terminal 10-3 and the signal terminal 10-4.
The shielding structure is as follows: the "shield shell 10-1 of the plug connector 10" surrounds the "RF signal terminals 10-3 of the plug connector 10" and the "RF signal terminals 20-3 of the receptacle connector 20" in cooperation with the "shield shell 20-1 of the receptacle connector 20" described below, thereby performing shielding.
Fig. 1b is a diagram showing the plug connector 10 of the present invention, and is a diagram showing a bottom surface of the plug connector 10 of fig. 1 a.
When viewed from the bottom, a portion where the shield case 10-1 is disposed is observed. A signal terminal 10-4 is disposed at a middle portion in the longitudinal direction of the plug connector 10.
The shield case 10-1 is disposed further to the outside (outside in the longitudinal direction (X direction) of the connector 10) than the signal terminal 10-4. An 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.
Fig. 2a is a diagram showing the receptacle connector 20 of the present invention.
The receptacle connector 20 is also referred to as a receptacle connector 20.
In fig. 2a, shield case 20-1, RF signal terminal 20-3, signal terminal 20-4, and housing (mold) 20-5 of receptacle connector 20 are shown.
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 of a relatively lower frequency than the RF signal terminal 20-3. The current at the power supply terminal level may also be passed to the signal terminal 20-4 as desired.
The shield case 20-1 serves to shield the RF signal terminal 20-3 that transmits and receives a high-frequency signal.
The housing (molded part) 20-5 of the receptacle connector 20 is preferably made of plastic, such as LCP (liquid Crystal Polymer). The RF signal terminals 20-3 and the signal terminals 20-4 of the receptacle connector 20 are preferably made of a metal material, for example, a copper alloy plated with gold (nickel base). 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 a plastic, a carbon material such as graphene, or the like, or may be made of a material similar to or the same as the RF signal terminal 20-3 and the signal terminal 20-4.
The shielding structure is as follows: the "shield shell 10-1 of the plug connector 10" and the "shield shell 20-1 of the receptacle connector 20" cooperate to surround the "RF signal terminal 10-3 of the plug connector 10" and the "RF signal terminal 20-3 of the receptacle connector 20" to thereby perform shielding.
Fig. 2b is a diagram showing the receptacle connector 20 according to the present invention, and is a diagram showing a bottom surface of the receptacle connector 20 of fig. 2 a.
When viewed from the bottom, a portion of the shield can 20-1 is observed. A signal terminal 20-4 is disposed in an intermediate portion in the longitudinal direction of the receptacle connector 20.
The shield shell 20-1 is disposed further to the outside (outside in the longitudinal direction (X direction) of the connector 20) than the signal terminal 20-4. In contrast to the plug connector 10 in which the shielding shells 10-1 having different shapes (i.e., the longer extension portions from the outer side to the inner side in the longitudinal direction) are mixed with the plug connector 10 as shown by reference numerals 10-1a and 10-1b, the shielding shells 20-1 have the same shape (in which they may be line-symmetrical in the longitudinal direction or the width direction) in the receptacle connector 20.
An 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, a direction (X, Y, Z) is arbitrarily set in fig. 1a, 1b, 2a, and 2b, but this direction is not maintained when the connectors 10 and 20 are coupled to each other, and when the plug connector 10 is coupled to the receptacle connector 20, it is necessary to turn over one of the connectors upside down and then perform the coupling.
Fig. 3 is a view showing a case where the housing 10-5 is removed in the plug connector 10 of fig. 1 a.
The housing 10-5 (not shown) is preferably a plastic fragment rather than a plastic assembly, and the shield case 10-1 is preferably a metal fragment rather than a metal assembly, but not limited thereto. In FIGS. 1a and 3, 4 shield cans 10-1 (two 10-1a and two 10-1b) are shown.
As shown in fig. 3, it can be seen that the shield case 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 of the shield case and at a position overlapping the shield case 10-1 in the longitudinal direction, and the signal terminal 10-4 is disposed on the inner side of the shield case 10-1. Each component is substantially in a point-symmetric configuration with reference to the center point in the longitudinal direction and the width direction of the connector 10. For example, as can be seen from fig. 3, the shield case 10-1a at the lower end of the left side and the shield case 10-1a at the upper end of the right side have 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 point-symmetric.
The RF signal terminal 10-3 includes a mounting portion 10-3-M for a substrate and a contact portion 10-3-C for the opposite 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 case 10-1.
Fig. 4 is a view showing a state where the housing 20-5 is removed from the receptacle connector 20 of fig. 2 a.
In fig. 4, the housing 20-5 (not shown) is preferably a plastic fragment rather than a plastic assembly, and the shield case 20-1 is preferably a metal fragment rather than a metal assembly, but not limited thereto. In fig. 2a, 4 shield cans 20-1 are shown.
It is confirmed that the shield shell 20-1 is disposed on the outermost side in the longitudinal direction (X direction) of the connector 20, the RF signal terminal 20-3 is disposed at a position overlapping the shield shell 20-1 in the longitudinal direction, and the signal terminal 20-4 is disposed inside the shield shell 20-1.
Further, the shield plates 10-1a-E of the shield case 10-1a as an example shown in FIG. 1a are inserted between the shield plates 20-1-E of the shield case 20-1 as an example shown in FIG. 5. The shield plates 20-1-E have, for example, two electrical contacts C1, C2, making electrical contact with the shield plates 10-1 a-E. As described below, 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 lower left 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 upper left end in fig. 4), the shield plates 10-1a-E are inserted between the contact C1 of the shield case 20-1 at the lower left end and the contact C1 of the shield case 20-1 at the upper left end, and between the contact C2 of the shield case 20-1 at the lower left end and the contact C2 of the shield case 20-1 at the upper left end, thereby being engaged with each other.
The RF signal terminal 20-3 includes a mounting portion 20-3-M for a substrate and a contact portion 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 case 20-1. In fig. 4, it can be seen that approximately 4 faces are enclosed from the perspective, but it is not known that the faces are completely enclosed.
Fig. 5 is an AA sectional view of the combination of the plug connector 10 of fig. 1a and the receptacle connector 20 of fig. 2 a.
Specifically, fig. 5 is an AA sectional view in the case where the plug connector 10 of fig. 1a is turned upside down and 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 the-Z direction (due to the upside down) for the plug connector 10.
For reference, the upper portion of the RF signal terminal 20-3 of fig. 5 is slightly bent inward when the RF signal terminal 20-3 is coupled with the RF signal terminal 10-3, but such bending is omitted in fig. 5 for convenience of illustration.
Fig. 6 is a BB cross-sectional view of the case of combining the plug connector 10 of fig. 1a with the receptacle connector 20 of fig. 2 a.
Specifically, fig. 6 is a BB cross-sectional view in the case where the plug connector 10 of fig. 1a is flipped up and down and 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 the-Z direction (due to the upside down) for the plug connector 10.
For reference, the upper portion of the signal terminal 20-4 of fig. 6 is slightly bent inward when the signal terminal 20-4 is coupled with the signal terminal 10-4, but such bending is omitted in fig. 6 for convenience of illustration.
Fig. 7 is a cross-sectional view CC 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 sectional view of the case where the plug connector 10 of fig. 1a is turned upside down and coupled to the receptacle connector 20 of fig. 2 a. That is, as can be seen from fig. 7, the direction X, Y, Z for the receptacle connector 20 is the same as the direction X, Y, Z of fig. 2a, and the Z-direction of fig. 1a is changed to the-Z-direction (due to the upside-down orientation) for the plug connector 10.
The shield plates 10-1a-E of the shield case 10-1a are inserted between the shield plates 20-1-E of the shield case 20-1. The shield plates 20-1-E have, for example, two electrical contacts C1, C2, and are thus in electrical contact with the shield plates 10-1 a-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 lower left 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 upper left end in fig. 4), and the shield plates 10-1a-E are inserted between the contact C1 of the shield case 20-1 at the lower left end and the contact C1 of the shield case 20-1 at the upper left end, and between the contact C2 of the shield case 20-1 at the lower left end and the contact C2 of the shield case 20-1 at the upper left end, thereby being engaged with each other. In fig. 7, a cross section is illustrated in the following case: the shield plates 10-1a-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 engaged with each other.
Fig. 8 is a view assuming that the housings 10-5, 20-5 are removed, respectively, in the coupled state of fig. 5 to 7.
Fig. 8 is a plan view of the coupled state of fig. 5 to 7 with the housings 10-5 and 20-5 removed, respectively, and may be considered as a view in which the plug connector 10 shown in fig. 3 is turned upside down and coupled to the receptacle connector 20 shown in fig. 4.
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 shield the "coupled body of the RF signal terminal 10-3 and the RF signal terminal 20-3" from surrounding.
In particular, in fig. 8, the shielding plates 10-1a-E and 20-1-E are provided 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, so that the shielding effect between them can be further improved.
On the other hand, as is clear from fig. 8 in which the connector 10 and the connector 20 are coupled to each other, approximately 4 surfaces of the "coupled body of the RF signal terminal 10-3 and the RF signal terminal 20-3" are surrounded by the "coupled body of the shield case 10-1 and the shield case 20-1". According to this structure, the electric signals of the RF signal terminals 10-3, 20-3 can be efficiently shielded.
In contrast to fig. 8, in fig. 3, approximately 3 faces of the RF signal terminal 10-3 are surrounded by the shield case 10-1, and in fig. 4, approximately 3 faces (or slightly open 4 faces) of the RF signal terminal 20-3 are surrounded by the shield case 20-1. 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.
Fig. 9 is a diagram for explaining the structure shown in fig. 8 in more detail.
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 joined between the two opposing contacts C1, and further, another portion of the shield plates 10-1a-E is joined between the two opposing contacts C2. With this configuration, the shield covers can be easily and firmly fastened to each other, and the shielding effect between the adjacent RF signal terminals can be exhibited.
As shown on the right side of fig. 9, a connected body (large square portion) of the RF signal terminal is present between the shield contact portion (left small square portion) and the other shield contact portion (right small square portion) in the X direction which is the longitudinal direction of the connector.
Fig. 10 is an enlarged view of the RF signal terminal 20-3 shown in fig. 4 and the like.
For example, if the RF signal terminal 20-3 arranged at the lower right end in fig. 4 is enlarged, it is as shown in fig. 10.
In fig. 10, in order to reduce the overall size of the connector 20, in the RF signal terminal 20-3, a contact portion 20-3-C is arranged in a direction of 90 degrees with respect to the mounting portion 20-3-M.
As is apparent 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 can be seen from fig. 9 and the like, the contact portion of the RF signal terminal 20-3 is coupled to the contact portion of the RF signal terminal 10-3 which is also formed in the width direction.
The contact portion 20-3-C shown in fig. 10 is an elastic portion and is a free end. On the other hand, the opposing portion (i.e., the contact portion 10-3-C of the RF signal terminal 10-3 of the plug connector 10) to which the contact portion 20-3-C of the RF signal terminal 20-3 of the receptacle connector 20 is coupled 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-line configuration, not in a straight-line configuration)

Character or

A zigzag structure), the entire width of the connector 20 becomes large.
In addition, as shown in FIG. 10, the 90 degree configuration of the mounting portion 20-3-M and the contact portion 20-3-C further enhances high frequency performance. That is, the RF signal terminal 20-3 of the structure of FIG. 10 can also handle higher frequencies than a 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 (i.e., a straight-line structure).
Fig. 11 is a diagram illustrating the structure shown in fig. 4 in more detail.
In fig. 11, portions indicated by 5 small squares are all mounting portions for a substrate. Fig. 11 is a plan view assuming that the housing 20-5 is removed from the receptacle connector 20, and thus the mounting portion can be fixed to a substrate (not shown) located therebelow by soldering or the like.
At this time, the mounting portion (also referred to as "inside mounting portion") 20-4-M2 of the signal terminal 20-4 is arranged between the mounting portion (also referred to as "RF mounting portion") 20-3-M of the RF signal terminal 20-3 and the mounting portion (also referred to as "shield mounting portion") 20-1-M of the shield case 20-1 in the width direction. If configured in this manner, the isolation (isolation) between the RF signal terminals 20-3 in the longitudinal direction is increased, so that signal interference, noise between the RF terminals, or the like is reduced. In addition, resonance between the RF terminals is also reduced.
That is, in the example of fig. 11, the isolation of the RF signal terminal 20-3 of the left lower end from the RF signal terminal 20-3 of the right lower end is improved. Similarly, the isolation between the RF signal terminal 20-3 at the upper end of the left side and the RF signal terminal 20-3 at the upper end of the right side is improved.
The inner attachment portion 20-4-M2 is exposed to the bottom surface and 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, such an exposed state can be confirmed in fig. 2b and 6.
Fig. 12 is a plug connector showing another embodiment.
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 the RF signal terminals 10-3' is 8, and there is no general signal terminal (for example, the signal terminal 10-4 in fig. 1a, etc.), but it is not limited thereto. However, the distinction between RF signal terminals and normal signal terminals is not absolute, and "RF signal terminals" mean that it is suitable for transmitting and receiving high frequency signals, and do not mean that it is not possible to transmit and receive signals of lower frequencies, so in the form of fig. 12, the plug connector 10 of fig. 1a can also operate sufficiently (the difference in the number of signal terminals 10-4 is not discussed). In fig. 12, the number of the shield cases 10-1' is 4, and two types are classified. Namely, two shield cans 10-1a ' having the shield plates 10-1a ' -E and two shield cans 10-1b ' having no shield plates are separated. This is also the case in figure 1 a.
Fig. 13 is a diagram showing a receptacle connector according to another embodiment.
The receptacle connector (receptacle connector) 20 'of fig. 13 is combined with the plug connector 10' of fig. 12.
If the connectors 10', 20' are coupled, the shield case 10-1', the shield case 20-1', and the metal members 20-11, 20-12 are coupled to each other. At this time, in the example of fig. 12, 13, 8 shield blocks are formed, whereby 8 pieces of the "combination of the RF signal terminal 10-3 'and the RF signal terminal 20-3', respectively" are electrically shielded with respect to each other. In fig. 13, 6 metal pieces 20-11, 20-12 are illustrated, which may be part of the shielding cage 20-1' or may be separate entities. Whether a portion or a separate body, the number of shield segments is also 8 when the connector 10 'is combined with the connector 20'. For example, the shield case 10-1' is known to connect the shield case 20-1' to the metal member 20-11, and to connect the shield case 20-1' to the metal member 20-12.
For example, in the claims of the present application, the first signal terminal represents the symbol 10-3 in fig. 1a, the second signal terminal represents the symbol 10-4 in fig. 1a, or the first signal terminal represents the left two and the right two of the 8 symbols 10-3 'of fig. 12, and the second signal terminal represents the middle 4 of the 8 symbols 10-3' of fig. 12.
Of course, in the claims of the present application, the first signal terminal represents the symbol 20-3 in fig. 2a, the second signal terminal represents the symbol 20-4 in fig. 2a, or the first signal terminal represents the left two and the right two of the 8 symbols 20-3 'of fig. 13, and the second signal terminal represents the middle 4 of the 8 symbols 20-3' of fig. 13.
The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited to the embodiments and can be manufactured in other various forms, and a person having ordinary skill in the art to which the present invention belongs will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features of the present invention. It is therefore to be understood that the above described embodiments are illustrative in all respects and not restrictive.
