Description

Electrical connector for high frequency

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

In general, when substrates are interconnected, two connectors connected to each substrate by a method such as soldering 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 socket connector. A socket connector is also called a receptacle connector. Such a plug connector and a socket connector may be formed by disposing terminals in a mold part. A plug connector and a socket connector may be engaged with each other to form an electrical connector assembly.

The mating portion of the socket terminal is liable to be deformed by repeated mating and disengagement or continuation of the coupled state, which adversely affects the strength of the coupling force or durability of the connector.

When sending and receiving a signal through the connector, the structure of the connector may vary according to the high and low frequencies of the signal. In particular, if the conventional connector is used as it is for 5G (5G) wireless communication, it may not operate properly.

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

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

In addition, it is also a problem to prevent physical damage to the terminals.

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 following description.

At least two of the plurality of second shields, at one end in the longitudinal direction of the electrical connector, each second shield plate is adjacent to each other in the width direction of the electrical connector,

When the first connector and the second connector are fitted to form a combined body, the first shield plate is positioned between two adjacently opposed second shield plates so that the first shield and the second shield are in contact with each other. An electrical connector to be electrically connected is provided.

Preferably, the second shield plate has at least two electrical contacts protruding in the width direction of the electrical connector,

When the first connector and the second connector are fitted to form a connector assembly, in the longitudinal direction of the electrical connector, the second connector is disposed between the at least two electrical contacts of the first shield plate and the second shield plate. A combination of the first signal terminal and the third signal terminal is disposed.

Preferably, between said at least two electrical contacts there is another electrical contact.

Preferably, in a state before the first connector and the second connector are fitted to form a connector assembly,

When the first connector is viewed from a height direction perpendicular to the length direction and the width direction, the first shield surrounds at least two surfaces of the first signal terminal,

When the second connector is viewed in a height direction perpendicular to the length direction and the width direction, the second shield surrounds at least two surfaces of the third signal terminal.

In the width direction, a signal terminal 20-4 is disposed 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. Since the mounting portion 20-4-M2 is positioned, isolation between the RF signal terminals 20-3 adjacent in the longitudinal direction is improved. This is also true for the connector 20 as well as the connector 10 .

In addition, since the RF signal terminals 10-3 and 20-3 have a structure having a longitudinal extension part and a width direction extension part (that is, a L-shape or a L-shaped structure), the size of the connector (in particular, the width direction size) 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 surrounding 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, in general, the structure after coupling of the shield 10-1 and the shield 20-1 is in the longitudinal direction and the width direction 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 functions 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, a physical force It can be seen that the combination of the RF signal terminal 10-3 and the RF signal terminal 20-3 is also protected from the above.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail 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, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention belongs It is provided to fully inform the possessor of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

1A shows a shield 10-1, an RF signal terminal 10-3, a signal terminal 10-4, and a housing 10-5 (mold portion) of the plug connector 10 . And, although not limited thereto, the shield 10 - 1 may have a different shape from that of the shield 10 - 1a or the shield 10 - 1b opposite thereto. 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 a 'shield plate'). That is, the shield 10-1a has projections 10-1a-E (shield plate) formed by bending approximately 90 degrees from the body of the shield as shown in FIG. 1A as an example, and the shield 10-1b has the projections. (10-1a-E) is absent. As will be described later, the shield plate 10-1a-E, which is the projection, is sandwiched between the shield plate 20-1-E, which is the projection 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 sending and receiving a high-frequency signal (eg, a frequency signal of about 50 GHz). The signal terminal 10 - 4 is a terminal for sending 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 necessary 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 for processing a frequency range processed by an existing connector before a 5G-compatible connector. Being used for 5G wireless communication is an example, and not necessarily limited thereto. If necessary, a current at the level of the power terminal may flow through the signal terminal 10 - 4 .

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 a resin and epoxy, but is not limited thereto.

The RF signal terminal 20 - 3 is a terminal for sending and receiving a high-frequency signal. The signal terminal 20 - 4 is a terminal for sending and receiving a signal of a relatively lower frequency than the RF signal terminal 20 - 3 . If necessary, a current at the level of the power 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 a metal, for example, gold plating (nickel underlayer) on a copper alloy. The shield 20-1 may be any electromagnetic wave shielding material, for example, a metal such as aluminum, a polymer composite material, a metal coated or sprayed on plastic, a carbon material such as graphene, etc., and the RF signal terminal 20- 3), the same or similar material to the signal terminal 20-4 may be used.

The shielding structure is specifically, 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 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'.

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

The shield 20-1 is disposed outside the signal terminal 20-4 (outside in the longitudinal direction (X direction) of the connector 20). However, unlike in the plug connector 10, shields 10-1 having different shapes (that is, the presence or absence of long extensions from the outside in the longitudinal direction to the inside) were mixed as indicated by reference numerals 10-1a and 10-1b. , in the socket connector 20 , the shield 20 - 1 has the same shape (however, it may have a line symmetrical shape in the longitudinal direction or the width direction).

The RF signal terminal 20 - 3 is present in 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. 1A, 1B, 2A, and 2B, such directions are not maintained when the connectors 10 and 20 are coupled to each other, and the plug connector 10 Of course, when trying to couple to the socket connector 20, one of the connectors must be turned upside down and then coupled.

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, the housing 10 - 5 (not shown) is preferably a piece of plastic rather than an assembly of plastic, and one shield 10 - 1 is a piece of metal rather than an assembly of metal. It is preferably a piece. It can be seen that 4 shields 10-1 (two 10-1a and two 10-1b) are shown in FIGS. 1A and 3 .

When viewed from the center point in the longitudinal direction and the width direction of the connector 10, roughly, each component has a point-symmetric structure. For example, it can be seen from FIG. 3 that the shield 10-1a at the lower left has a point-symmetric shape with the shield 10-1a at the upper right. Also, in FIG. 3 , it can be seen that the shield 10-1b at the upper left has a point-symmetric shape with the shield 10-1b at the lower right.

The RF signal terminal 10-3 includes a mounting portion 10-3-M on the board and a contact portion 10-3-C on 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 substantially surrounded by the shield 10-1 on three sides.

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 the shield 20-1 on approximately three sides. In FIG. 4 , depending on the viewpoint, it can be seen that it is surrounded by approximately four sides, but it can be seen that it is not completely surrounded.

FIG. 5 is a cross-sectional view AA of a combination of the plug connector 10 of FIG. 1A and the socket connector 20 of FIG. 2A .

Specifically, FIG. 5 is an AA cross-sectional view of the plug connector 10 of FIG. 1A being vertically inverted 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 of FIG. 2A for the socket connector 20 , and the Z direction of FIG. 1A for the plug connector 10 (since it is 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 combined, the upper part of the RF signal terminal 20-3 of FIG. 5 will be slightly bent inward, but FIG. 5 shows For the sake of convenience, such bending is omitted.

FIG. 6 is a BB cross-sectional view showing a combination of the plug connector 10 of FIG. 1A and the socket connector 20 of FIG. 2A .

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

FIG. 7 is a CC sectional view showing a combination of the plug connector 10 of FIG. 1A and the socket connector 20 of FIG. 2A .

Specifically, FIG. 7 is a CC sectional view of the plug connector 10 of FIG. 1A being vertically inverted and coupled to the socket connector 20 of FIG. 2A . That is, in FIG. 7 , the X, Y, and Z directions are the same as the X, Y, and Z directions of FIG. 2A for the socket connector 20 , and the Z direction of FIG. 1A for the plug connector 10 (since they are inverted) You will notice that this has changed in the -Z direction.

The shield plates 10-1a-E of the shield 10-1a are 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 make electrical contact with the shield plate 10-1a-E. More specifically, this shield plate 10-1a-E is different from the shield plate 20-1-E of one shield 20-1 (for example, the shield at the lower left in Fig. 4) and the other shield 20-1. ; For example, in Fig. 4, it is sandwiched between the shield plate 20-1-E of the upper left shield), and the contact C1 of the lower left shield 20-1 and the left upper shield 20-1 are interposed. A shield plate 10-1a-E is formed between the contact point C1 and between the contact point C2 of the shield 20-1 at the lower left and the contact point C2 of the shield 20-1 at the upper left. They come into contact with each other by being fitted. FIG. 7 is a cross-sectional view showing a contact point C2 of one shield 20-1 and a contact point C2 of the other shield 20-1 with the shield plates 10-1a-E sandwiched therebetween. has been

8 is a view showing each of the housings 10-5 and 20-5 virtually removed in the coupled state of FIGS. 5 to 7 .

This is viewed from above by virtually removing each housing 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. 3 . It can also be thought of as being coupled to the socket connector 20 that has been used.

As shown in FIG. 8 , the RF signal terminal 10 - 3 and the RF signal terminal 20 - 3 are coupled. Then, the shield 20-1 and the shield 10-1 are combined to shield the 'combined body of the RF signal terminal 10-3 and the RF signal terminal 20-3'.

In particular, in FIG. 8 , 'a combination of the RF signal terminal 10-3 and the RF signal terminal 20-3' on the upper left and the 'RF signal terminal 10-3 and the RF signal terminal 20-3 on the lower left side of FIG. ), the shield plate (10-1a-E) and the shield plate (20-1-E) exist between the 'combination body', so that the mutual shielding effect can be further increased.

On the other hand, in FIG. 8 in which 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 -1) and the combination of the shield 20-1” can be seen. With this structure, the shielding of the electrical signals of the RF signal terminals 10-3 and 20-3 is efficiently performed.

This means that the RF signal terminal 10-3 in FIG. 3 is surrounded by the shield 10-1 on approximately three sides, and the RF signal terminal 20-3 in FIG. 4 is approximately three sides (or slightly open 4). surface) in contrast to that surrounded by the shield 20-1. That is, FIGS. 3 and 4 show before the connectors 10 and 20 are coupled with each other, and FIG. 8 shows after the connectors 10 and 20 are coupled with each other.

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

9, the shield plates 10-1a-E of the shield 10-1a are sandwiched between the respective shield plates 20-1-E of the two shields 20-1. When fitted, the shield plate 10-1a-E is in contact between the two opposing contact points c1, and another portion of the shield plate 10-1a-E is in contact between the two opposing contact points c2. touch Due to this structure, the shields can be easily and securely fastened, and the shielding effect of adjacent RF signal terminals is also exhibited.

In addition, as seen from the right side of FIG. 9, the combination of the RF signal terminal (larger square part) between the shield contact part (small square part on the left) and the other shield contact part (small square part on the right) in the X direction, which is the longitudinal direction of the connector. square) is present.

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

For example, when the RF signal terminal 20-3 disposed at the lower right in FIG. 4 is enlarged, 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, the contact portion 20-3-C in the direction of 90 degrees with respect to the mounting portion 20-3-M. is placed

And, although not limited thereto, in FIG. 10 , it can be seen that the contact portion 20-3-C of the RF signal terminal 20-3 is formed in the width direction (the Y direction). This is coupled to the contact portion of the RF signal terminal 10-3, which is also formed in the width direction, as can be seen in FIG. 9 and the like.

The contact portion 20-3-C shown in FIG. 10 is an elastic portion and a free end. On the other hand, although not limited thereto, the counterpart portion coupled to the contact portion 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 part 20-3-M is in the -Y direction and the contact part 20-3-C is in the -X direction, but if the mounting part 20-3-M is in the -Y direction direction and the contact portion 20-3-C is in the +Y direction (that is, if the RF signal terminals 10-3 and 20-3 have a straight-line structure instead of a L-shaped or L-shaped structure), There is a disadvantage of increasing the overall width.

In addition, the structure in which the mounting part 20-3-M and the contact part 20-3-C form 90 degrees as shown in FIG. 10 improves the 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, a straight-line structure), the RF signal terminal of the structure of FIG. 10 . (20-3) can also respond to higher frequencies.

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

In FIG. 11 , all portions indicated by five small squares indicate mounting portions on the substrate. 11 is a view from above with the housing 20 - 5 virtually removed from the socket connector 20 , so the mounting part will be fixed to a board (not shown) under it by soldering or the like.

At this time, in the width direction, the mounting part 20-3-M of the RF signal terminal 20-3 and the mounting part 20-1-M of the shield 20-1 (also referred to as 'RF mounting part') and the 'shield' A mounting unit 20-4-M2 (also referred to as an 'inner 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 resonance between 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 degree of separation between the upper left RF signal terminal 20-3 and the right upper RF signal terminal 20-3 is improved.

The inner mounting portion 20-4-M2 is exposed to 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 'tip mounting part') on the outside. This exposure state can also be confirmed in FIGS. 2B and 6 .

12 is a view 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' in the plug connector 10' may be present compared to the case of FIG. 1A. Although not limited thereto, in the example of FIG. 12 , eight RF signal terminals 10-3 ′ exist, and general signal terminals (eg, the signal terminal 10-4 in FIG. 1A ) do not exist. . However, the distinction between the RF signal terminal/general signal terminal is not absolute, and the name 'RF signal terminal' means that it is appropriate for transmitting and receiving high-frequency signals, but does not mean that signals of lower frequencies cannot be transmitted/received. Even in the form of Fig. 12, the operation performed by the plug connector 10 of Fig. 1A can be sufficiently performed (a difference in the number of signal terminals 10-4 is not discussed). In Fig. 12, four shields 10-1' are provided, and they are divided into two types. That is, there are two shields 10-1a' with the shield plate 10-1a'-E and two shields 10-1b' without the shield plate. This is the same as described in FIG. 1A.

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

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

When the connectors 10' and 20' are coupled to each other, the shield 10-1', the shield 20-1', and the metal fittings 20-11 and 20-12 are all coupled to each other. This forms eight shielding compartments in the example of FIGS. 12 and 13 , and accordingly, eight 'a combination of the RF signal terminal (10-3') and the RF signal terminal (20-3') are electrically connected to each other. is shielded with In FIG. 13, six metal fittings 20-11 and 20-12 are exemplified, and these metal fittings may be a part of the shield 20-1' or may be separate pieces. Whether part or separate, when the connector 10' and the connector 20' are coupled, it is the same that there are eight shielding compartments. For example, it can be seen that the shield 10-1' connects the shield 20-1' and the metal fitting 20-11, and also connects the shield 20-1' and the metal fitting 20-12.

For example, in the claims of the present application, the first signal terminal may be denoted by reference numeral 10-3 of FIG. 1A , the second signal terminal may be designated by reference numeral 10-4 of FIG. 1A , or the first signal terminal may be denoted by reference numeral 10-4 of FIG. 12 . The left two and the right two of the eight reference numerals 10-3' may be indicated, and the second signal terminal may indicate the middle four of the eight eight reference numerals 10-3' of FIG. 12 .

Of course, in the claims of the present application, the first signal terminal may be denoted by reference numeral 20-3 of FIG. 2A, the second signal terminal may be denoted by reference numeral 20-4 of FIG. 2A, or the first signal terminal may be denoted by reference numeral 20-4 of FIG. 13 . The left two and the right two among the eight reference numerals 20-3' may be indicated, and the second signal terminal may indicate the middle four of the eight eight reference numerals 20-3' of FIG. 13 .
