Description

Electric connector for high frequency {ELECTRIC CONNECTOR FOR RADIO FREQUENCY}

The present invention relates to electrical connectors for high frequencies. More specifically, the present invention relates to an electrical connector for high frequency that improves electromagnetic shielding performance, reduces longitudinal/width direction interference or noise between high frequency signal terminals, reduces the width of the connector, and reduces the possibility of physical damage to the terminal. will be.

In general, when boards are connected to each other, two connectors connected to each board are used by a method such as soldering, 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 socket connector. A socket connector is also called a receptacle connector. These plug connectors and socket connectors may be formed by arranging terminals in a mold unit. A plug connector and a socket connector may be mated to each other to form an electrical connector assembly.

The coupling portion of the socket terminal is easily deformed by repeated engagement and release or continued engagement, which adversely affects the strength of coupling force or durability of the connector.

In transmitting and receiving signals through the connector, the structure of the connector may vary according to the high and low frequencies of the signal. In particular, if a conventional connector is used as it is for 5th generation (5G) wireless communication, there may be cases where it does not operate properly.

A technical problem to be solved by the present invention is to improve electrical characteristics of a connector at a high frequency corresponding to 5G wireless communication. In particular, as an EMI characteristic, complete shielding of electromagnetic waves is made a subject. Interference between RF signal terminals may be interference between two or more terminals in the length direction or between two or more terminals in the width direction, both of which should be considered as important.

Another object is to reduce the size (for example, the size in the width direction) of the connector while maintaining strong coupling between the terminals.

Moreover, it is also made into a subject to prevent physical damage of a terminal.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

According to the present invention, as an electrical connector fitted with a mating connector,

mold part;

a plurality of shields disposed to surround at least a portion of an outer circumferential surface of the mold unit;

a first signal terminal disposed in the mold part and transmitting and receiving an RF signal; and

A second signal terminal disposed in the mold part and further inward than the first signal terminal in the longitudinal direction of the electrical connector.

Including,

The shield includes a longitudinal mounting part formed on an outer circumferential surface of the mold part extending in the longitudinal direction,

The first signal terminal includes a mounting portion that is mounted on a board,

The second signal terminal includes an inner mounting portion that is mounted on the board,

The inner mounting portion of the second signal terminal is disposed between the mounting portion of the first signal terminal and the mounting portion of the shield in the longitudinal direction in the width direction of the electrical connector, and in the longitudinal direction, the first signal terminal mounting portion is disposed between the first signal terminal mounting portion and the shield mounting portion. An electrical connector is provided that does not overlap the mounting portion of the terminal and the mounting portion in the longitudinal direction of the shield.

Preferably, the shield further includes a width direction mounting portion formed on an outer circumferential surface extending in the width direction of the electrical connector,

The second signal terminal further includes an outer mounting portion outside the mounting portion of the second signal terminal in the width direction of the electrical connector.

Preferably, the electrical connector is in a state before the mating connector is fitted to form an assembly,

Looking at the electrical connector from a height direction orthogonal to the longitudinal and width directions, the shield surrounds at least two surfaces of the first signal terminal.

Preferably, when the electrical connector is fitted with the mating connector to form a connector assembly, when the connector assembly is viewed in a height direction orthogonal to the longitudinal and width directions, the shield of the electrical connector and the mating connector are formed. A combination of shields surrounds four surfaces of the combination of the first signal terminal of the electrical connector and the first signal terminal of the mating connector.

Preferably, when viewing the electrical connector in a height direction orthogonal to the length direction and the width direction,

(i) based on the center point of the electrical connector, the electrical connector has a point-symmetric structure; or

(ii) With respect to a center line extending in the longitudinal direction passing through the center point of the electrical connector, the electrical connector has an axisymmetric structure.

According to embodiments of the technical idea of the present invention, at least the following effects are provided.

The shield plate 10-1a-E and the shield plate 20-1-E are effectively fitted and coupled to block signal interference or noise between RF signal terminals adjacent in the width direction.

The shield plate 10-1a-E and the shield plate 20-1-E are efficiently fit together to shield the four surfaces of the RF signal terminals 10-3 and 20-3 in the longitudinal and width directions. Thus, signal interference or noise between adjacent RF signal terminals is blocked, and signal interference or noise from other sources (eg, signal terminals 10-4 and 20-4) is also blocked.

In the width direction, between the mounting portion 20-1-M of the shield 20-1 and the mounting portion 20-3-M of the RF signal terminal 20-3, the signal terminal 20-4 Since the mounting portion 20-4-M2 is located, isolation between adjacent RF signal terminals 20-3 in the longitudinal direction is improved. This is true for the connector 10 as well as the connector 20 .

In addition, since the RF signal terminals 10-3 and 20-3 have a structure having a lengthwise extension part and a widthwise extension part (ie, L-shaped or L-shaped structure), the size of the connector (in particular, the size in the width direction) is reduced compared to the straight structure. While reducing, stable coupling and higher frequency performance can be achieved.

The 'shield 10-1 of the plug connector 10' and the 'shield 20-1 of the socket connector 20' cooperate to form the 'RF signal terminal 10-3 of the plug connector 10' and ' By enclosing the RF signal terminal 20-3' of the socket connector 20, electromagnetic wave shielding is performed.

In order to shield the RF signal terminals 10-3 and 20-3 well, overall, the structure after coupling of the shield 10-1 and the shield 20-1 is in the longitudinal and width directions of the connectors 10 and 20 surrounds the RF signal terminals 10-3 and 20-3.

The combination of the shield 10-1 and the shield 20-1 serves to shield electromagnetic waves from the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3, and at the same time provides physical force. It can also be seen as protecting the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3.

Advantages and features of the present invention, and methods of achieving them, will become clear with reference to the detailed description of the following embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, only these embodiments make the disclosure of the present invention complete, and common knowledge in the art to which the present invention belongs. It is provided to fully inform the holder of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numbers designate like elements throughout the specification.

1A is a diagram showing a plug connector 10 according to the present invention.

1A shows a shield 10-1, an RF signal terminal 10-3, a signal terminal 10-4, and a housing 10-5 (molded part) of the plug connector 10. And, although not limited thereto, the shield 10-1 may have a different shape, such as the shield 10-1a or the opposite shield 10-1b. Among the shields 10-1, the main difference between the shield 10-1a and the shield 10-1b is the presence or absence of protrusions 10-1a-E (also referred to as 'shield plate'). That is, the shield 10-1a has a protrusion 10-1a-E (shield plate) formed by being bent at approximately 90 degrees from the main body of the shield as shown in FIG. 1A as an example, and the shield 10-1b has a protrusion. (10-1a-E) is absent. As will be described later, the shield plate 10-1a-E, which is the protrusion, is sandwiched between the shield plates 20-1-E, which is the protrusion of the shield 20-1 of the socket connector 20, which is the mating connector.

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 for transmitting and receiving a signal of a relatively lower frequency than the RF signal terminal 10-3. The signal terminal 10-4 may be referred to as a general signal terminal as needed to distinguish it from the RF signal terminal 10-3. However, although it is preferable to send a high frequency signal to the RF signal terminal 10-3, sending a high frequency signal to the general signal terminal 10-4 is not completely excluded. The signal terminal 10 - 4 may be a terminal that handles a frequency range that was handled in an existing connector prior to the 5G compatible connector. Being used for 5G wireless communication is an example, and is not necessarily limited thereto. If necessary, a current at the level of the power supply terminal may flow through the signal terminal 10-4. As an example, the signal terminal 10-4 may consist of 6 PINs that allow a current of 0.3A, or may be a terminal that allows a current of more than 0.3A, for example, up to 5A to function as a power terminal. . However, it is an example that the number of PINs is six.

The shield 10-1 (10-1a and/or 10-1b) serves to shield the RF signal terminal 10-3 that transmits and receives a high-frequency signal.

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

The housing 10 - 5 (mold part) 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 resin and epoxy, but is not limited thereto. The RF signal terminal 10-3 and the signal terminal 10-4 of the plug connector 10 are preferably made of metal, but are not limited thereto. under layer).

The shielding structure is specifically defined by the cooperation of the 'shield 10-1 of the plug connector 10' and the 'shield 20-1 of the socket connector 20', which will be described later, in cooperation with the 'RF signal of the plug connector 10'. Shielding is performed by surrounding the terminal 10-3 and the RF signal terminal 20-3 of the socket connector 20.

Figure 1b shows a plug connector 10 according to the present invention, and is a view showing the bottom of the plug connector 10 of Figure 1a.

When viewed from the bottom, a part of the shield 10-1 is seen to be disposed. A signal terminal 10-4 is disposed at the center of the plug connector 10 in the longitudinal direction.

A shield 10-1 is disposed outside the signal terminal 10-4 (outside in the longitudinal direction (X direction) of the connector 10). An RF signal terminal 10-3 exists at a portion overlapping the shield 10-1 in the longitudinal direction (X direction) of the connector 10.

The receptacle connector 20 is also called a socket connector 20.

2A shows a shield 20-1, an RF signal terminal 20-3, a signal terminal 20-4, and a housing 20-5 (molding part) of the socket 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 for transmitting and receiving a signal of a relatively lower frequency than the RF signal terminal 20-3. If necessary, a current of the level of the power supply terminal may flow through the signal terminal 20-4.

The shield 20-1 serves to shield the RF signal terminal 20-3 that transmits and receives a high-frequency signal.

The housing 20 - 5 (mold part) of the receptacle connector 20 is preferably made of a plastic material, and may be, for example, liquid crystal polymer (LCP). The RF signal terminal 20 - 3 and the signal terminal 20 - 4 of the receptacle connector 20 are preferably made of metal, and may be, for example, copper alloy plated with gold (nickel under layer). The shield 20-1 may be any material that shields electromagnetic waves, and may be, for example, a metal such as aluminum, a polymer composite material, a metal coated or sprayed on plastic, a carbon material such as graphene, or the like, and an RF signal terminal (20-1). 3), it may be made of the same or similar material as the signal terminal 20-4.

The structure of the shield is specifically, the 'shield 10-1 of the plug connector 10' and the 'shield 20-1 of the socket connector 20' cooperate to 'RF signal of the plug connector 10' Shielding is performed by surrounding the terminal 10-3 and the RF signal terminal 20-3 of the socket connector 20.

Figure 2b shows the receptacle connector 20 according to the present invention, and is a view showing the bottom of the receptacle connector 20 of Figure 2a.

When viewed from the bottom, part of the shield 20-1 is visible. A signal terminal 20-4 is disposed at a central portion of the receptacle connector 20 in the longitudinal direction.

A shield 20-1 is disposed outside the signal terminal 20-4 (outside in the longitudinal direction (X direction) of the connector 20). However, in the plug connector 10, unlike the mixed shields 10-1 having different shapes (ie, the presence or absence of a long extension from the outside to the inside in the longitudinal direction) as shown in reference numerals 10-1a and 10-1b. , In the socket connector 20, the shield 20-1 has the same shape (however, it may have an axisymmetric shape in the longitudinal direction or the width direction).

An RF signal terminal 20-3 exists at a portion overlapping the shield 20-1 in the longitudinal direction (X direction) of the connector 20.

For reference, although directions (X, Y, Z) are arbitrarily set in FIGS. Of course, when trying to couple to the socket connector 20, it must be coupled after inverting any one connector upside down.

FIG. 3 shows a state in which the housing 10-5 is removed from the plug connector 10 of FIG. 1A.

Although not limited thereto, it is preferable that the housing 10-5 (not shown) is a plastic assembly rather than a plastic assembly, and the shield 10-1 is a metal assembly rather than a metal assembly. It is preferable to be a piece. 1a, 3 it can be seen that four shields 10-1 (two 10-1a and two 10-1b) are shown.

Roughly, each component has a point-symmetric structure when viewed from the center point of the longitudinal direction and the width direction of the connector 10 as a standard. For example, it can be seen from FIG. 3 that the shield 10-1a at the lower left has a point-symmetrical shape with the shield 10-1a at the upper right. In addition, it can be seen from FIG. 3 that the shield 10-1b at the upper left has a point-symmetrical shape with the shield 10-1b at the lower right.

The RF signal terminal 10-3 includes a mounting portion 10-3-M to the board and a contact portion 10-3-C to the mating connector 20 at both ends thereof. Although not limited thereto, the contact portion 10-3-C may be a fixed end.

In FIG. 3, the RF signal terminal 10-3 is surrounded by a shield 10-1 on approximately three sides.

FIG. 4 shows a state in which the housing 20-5 is removed from the socket connector 20 of FIG. 2A.

In FIG. 4(a), although not limited thereto, the housing 20-5 (not shown) is preferably not an assembly of plastic but a piece of plastic, and one shield 20-1 is made of metal. It is preferable that it is not an assembly of but a single piece of metal. 2a and 4, it can be seen that four shields 20-1 are shown.

Along the longitudinal direction (X direction) of the connector 20, the shield 20-1 is at the outermost side, and the RF signal terminal 20-3 and the shield 20-1 are overlapped with the shield 20-1 in the longitudinal direction. 1) It can confirm that the signal terminal 20-4 is arrange|positioned inside.

The RF signal terminal 20-3 includes a mounting portion 20-3-M to the board and a contact portion 20-3-C to the mating connector 10 at both ends thereof. Although not limited thereto, it is preferable that the contact portion 20-3-C is a free end.

In FIG. 4, the RF signal terminal 20-3 is surrounded by a shield 20-1 on approximately three sides. In FIG. 4 , depending on the point of view, it may be seen as being surrounded on approximately four sides, but it can be seen that it is not completely surrounded.

Specifically, FIG. 5 is an AA cross-sectional view of the plug connector 10 of FIG. 1A vertically reversed and coupled to the socket connector 20 of FIG. 2A. That is, in FIG. 5, the X, Y, and Z directions are the same as the X, Y, and Z directions in FIG. 2A for the socket connector 20, and the Z directions in FIG. 1A for the plug connector 10 (because they are upside down). You will notice that this has changed in the -Z direction.

For reference, when the RF signal terminal 20-3 and the RF signal terminal 10-3 are coupled, the upper portion of the RF signal terminal 20-3 in FIG. 5 will be slightly bent inward, but FIG. For convenience, such warping is omitted.

Specifically, FIG. 6 is a BB cross-sectional view of the plug connector 10 of FIG. 1A vertically reversed and coupled to the socket connector 20 of FIG. 2A. That is, in FIG. 6, the X, Y, and Z directions are the same as the X, Y, and Z directions in FIG. 2A for the socket connector 20, and the Z direction in FIG. 1A for the plug connector 10 (because they are reversed). You will notice that this has changed in the -Z direction.

For reference, when the signal terminal 20-4 and the signal terminal 10-4 are coupled, the upper portion of the signal terminal 20-4 in FIG. 6 will be slightly bent inward, but FIG. 6 is for convenience of illustration. For this reason, such warping is omitted.

That is, in FIG. 7, the X, Y, and Z directions are the same as the X, Y, and Z directions in FIG. 2A for the socket connector 20, and the Z directions in FIG. 1A for the plug connector 10 (because they are reversed). You will notice that this has changed in the -Z direction.

The shield plate 10-1a-E of the shield 10-1a is sandwiched between the shield plates 20-1-E of the shield 20-1. The shield plate 20-1-E has, for example, two electrical contact points C1 and C2 to electrically contact the shield plate 10-1a-E. More specifically, this shield plate 10-1a-E is a shield plate 20-1-E of one shield 20-1 (e.g., the shield at the lower left in Fig. 4) and another shield 20-1. ; For example, it is inserted between the shield plate 20-1-E of the upper left shield in FIG. 4, and the contact C1 of the shield 20-1 at the lower left and the shield 20-1 at the upper left Shield plates 10-1a-E are provided between the contacts C1 and between the contact C2 of the shield 20-1 at the lower left and the contact C2 of the shield 20-1 at the upper left.

FIG. 8 shows the housings 10-5 and 20-5 virtually removed in the coupled state of FIGS. 5 to 7 .

This is a view from above by virtually removing each of the housings 10-5 and 20-5 in the coupled state of FIGS. 5 to 7, and also shown in FIG. 4 by inverting the plug connector 10 shown in FIG. It may be thought that it is coupled to the socket connector 20.

As shown in Figure 8, the RF signal terminal 10-3 and the RF signal terminal 20-3 are coupled. In addition, the shield 20-1 and the shield 10-1 are combined to shield the 'combination of the RF signal terminal 10-3 and the RF signal terminal 20-3' as if to surround it.

In particular, in FIG. 8, the 'combination of the RF signal terminal 10-3 and the RF signal terminal 20-3' at the upper left and the 'RF signal terminal 10-3 and the RF signal terminal 20-3 at the lower left Since the shield plate 10-1a-E and the shield plate 20-1-E are present between the 'combination body', mutual shielding effect can be further enhanced.

On the other hand, in FIG. 8 where the connector 10 and the connector 20 are coupled, the 'combination of the RF signal terminal 10-3 and the RF signal terminal 20-3' is approximately the 'shield 10' on four sides. -1) and the shield 20-1'. With this structure, shielding of the electric signals of the RF signal terminals 10-3 and 20-3 is performed efficiently.

3, the RF signal terminal 10-3 is surrounded by the shield 10-1 on approximately three sides, and the RF signal terminal 20-3 in FIG. side) can be contrasted with being surrounded by the shield 20-1. That is, FIGS. 3 and 4 show connectors 10 and 20 before being coupled to each other, and FIG. 8 shows connectors 10 and 20 after being coupled to each other.

FIG. 9 is a diagram for explaining the structure shown in FIG. 8 in more detail.

As shown in Fig. 9, the shield plate 10-1a-E of the shield 10-1a is sandwiched between the respective shield plates 20-1-E of the two shields 20-1. When being inserted, the shield plate 10-1a-E is in contact between the two opposing contact points c1, and the other part of the shield plate 10-1a-E is between the two opposing contact points c2. touch Due to this structure, fastening of the shields is performed easily and firmly, and the shielding effect of the adjacent RF signal terminals is also exhibited.

In addition, as shown on the right side of FIG. 9, in the X direction, which is the longitudinal direction of the connector, a combination of RF signal terminals (large square part on the left) between the shield contact part (small square part on the left) and another shield contact part (small square part on the right) square part) exists.

10 is an enlarged view of the RF signal terminal 20-3 shown in FIG. 4 and the like.

For example, an enlarged view of the RF signal terminal 20-3 disposed at the lower right in FIG. 4 is shown in FIG. 10.

10, in order to reduce the overall size of the connector 20, in the RF signal terminal 20-3, the contact portion 20-3-C is formed in a direction of 90 degrees with respect to the mounting portion 20-3-M. is placed

And, although not limited to this, it can be seen from FIG. 10 that the contact portion 20-3-C of the RF signal terminal 20-3 is formed in the width direction (Y direction). As can be seen in FIG. 9 and the like, this is combined with 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 has a free end. On the other hand, although not limited thereto, the counterpart part coupled to the contact part 20-3-C of the RF signal terminal 20-3 of the socket connector 20 (ie, the RF signal terminal of the plug connector 10) The contact portion (10-3-C) of (10-3) may be formed so as not to be a free end.

For reference, in FIG. 10, the mounting unit 20-3-M is in the -Y direction and the contact unit 20-3-C is in the -X direction, but if the mounting unit 20-3-M is in the -Y direction, direction and if the contact portion 20-3-C is in the +Y direction (ie, if the RF signal terminals 10-3 and 20-3 are not a L-shaped or L-shaped structure but a straight-shaped structure), the connector 20 The downside is that the overall width is increased.

In addition, as shown in FIG. 10, the structure in which the mounting portion 20-3-M and the contact portion 20-3-C form an angle of 90 degrees improves high frequency performance. That is, compared to the structure in which the mounting part 20-3-M is in the -Y direction and the contact part 20-3-C is in the +Y direction (ie, the straight structure), the RF signal terminal of the structure of FIG. 10 (20-3) can also respond to higher frequencies.

FIG. 11 is a diagram for explaining the structure shown in FIG. 4 in more detail.

In FIG. 11, all of the parts marked with five small squares indicate mounting parts on the board. 11 is a view from above after virtually removing the housing 20-5 from the socket connector 20, so that the mounting portion will be fixed to a board (not shown) below it by soldering or the like.

At this time, in the width direction, the mounting unit 20-3-M (also referred to as 'RF mounting unit') of the RF signal terminal 20-3 and the mounting unit 20-1-M of the shield 20-1; The mounting unit 20-4-M2 (also referred to as 'inside mounting unit') of the signal terminal 20-4 is disposed between the mounting units'). With this arrangement, isolation between the RF signal terminals 20-3 in the longitudinal direction is improved, and signal interference or noise between the RF terminals is reduced. It also reduces the resonance between the RF terminals.

That is, in the example of FIG. 11, the degree of separation between the lower left RF signal terminal 20-3 and the lower right RF signal terminal 20-3 is improved. Similarly, the separation between the RF signal terminal 20-3 at the upper left and the RF signal terminal 20-3 at the upper right is improved.

The inner mounting part 20-4-M2 is exposed on the bottom surface and fixed to a substrate (not shown). This exposure state can also be confirmed in FIGS. 2B and 6 .

In addition, the signal terminal 20-4 has another mounting part (20-4-M1; also referred to as a 'front end mounting part') on the outside. This exposure state can also be confirmed in FIGS. 2B and 6 as well.

12 is a diagram showing a plug connector according to another embodiment.

As can be seen in FIG. 12, a larger number (eg, 8) of RF signal terminals 10-3' may be present in the plug connector 10' than in the case of FIG. 1A. Although not limited to this, in the example of FIG. 12, there are 8 RF signal terminals 10-3', and there are no general signal terminals (e.g., signal terminal 10-4 in FIG. 1A, etc.). . However, the distinction between the RF signal terminal/general signal terminal is not absolute, and the name 'RF signal terminal' means that it is suitable for transmitting and receiving high-frequency signals, but does not mean that lower-frequency signals cannot be transmitted and received. Even in the form of FIG. 12, the operation performed by the plug connector 10 of FIG. 1A can be sufficiently performed (the difference in the number of signal terminals 10-4 is out of the question). In Fig. 12, four shields 10-1' are provided, and are divided into two types. That is, two shields 10-1a' with shield plates 10-1a'-E and two shields 10-1b' without shield plates. This is also as described in FIG. 1A.

13 is a diagram showing a receptacle connector according to another embodiment.

The socket connector (20'; receptacle connector) of FIG. 13 is combined with the plug connector 10' of FIG.

When the connectors 10' and 20' are coupled together, the shield 10-1', the shield 20-1', and the fittings 20-11 and 20-12 are all coupled to each other. 12 and 13, eight shielding partitions are formed, and accordingly, the eight 'combination of the RF signal terminal 10-3' and the RF signal terminal 20-3' are electrically connected to each other. is shielded with 13 illustrates six fittings 20-11 and 20-12, and these fittings may be part of the shield 20-1' or may be a separate body. It is the same that when the connector 10' and the connector 20' are combined, whether as a part or as a separate body, the number of shielding compartments becomes eight. For example, it can be seen that the shield 10-1' connects the shield 20-1' and the fitting 20-11, and also connects the shield 20-1' and the fitting 20-12.

For example, in the claims of the present application, the first signal terminal may be indicated by reference numeral 10-3 in FIG. 1A, and the second signal terminal may be indicated by reference numeral 10-4 in FIG. 1A, or the first signal terminal may be indicated by reference numeral 10-4 in FIG. Left two and right two of the eight reference numerals 10-3' are indicated, and the second signal terminal may also indicate the middle four of the eight reference numerals 10-3' in FIG.

Of course, in the claims of the present application, the first signal terminal may be indicated by reference numeral 20-3 in FIG. 2A, and the second signal terminal may be indicated by reference numeral 20-4 in FIG. 2A, or the first signal terminal may be indicated by reference numeral 20-4 in FIG. Left two and right two of the eight reference numerals 20-3' are indicated, and the second signal terminal may also indicate the middle four of the eight reference numerals 20-3' in FIG.
