Description

TECHNICAL FIELD The present invention relates generally to an electrical connector and an electronic device including the electrical connector, and more particularly to suppressing crosstalk through a ground plate between two pairs of high frequency signal contact pairs arranged on the same plane. The present invention also relates to an electrical connector capable of preventing warping and bending of an internal structure, and an electronic device including the electrical connector.

Conventionally, electrical connectors are used to electrically connect electronic devices with other electronic devices. In order to obtain an electrical connection between an electronic device and another electronic device, it is mounted on a circuit board provided in the housing of the electronic device and is inserted from a through hole provided in the housing of the electronic device. Two types of electrical connectors are used in combination: a receptacle connector in which is exposed to the outside of the electronic device, and a plug connector that is inserted into the insertion port of the receptacle connector.

In addition, with the recent miniaturization of electronic devices, there is an increasing demand for miniaturization of electrical connectors. In response to the demand for miniaturization of such electrical connectors, the USB Type-C standard has been proposed. An electrical connector that conforms to the USB Type-C standard employs a vertically symmetrical design, enabling the plug connector to be inserted into the receptacle connector regardless of the vertical orientation of the connector.

A receptacle connector conforming to the USB Type-C standard includes a metal shell and an internal structure housed inside the shell. The internal structure includes a plurality of contacts that respectively contact a plurality of mating connectors (plug connectors), a ground plate, and an insulator that holds the plurality of contacts and the ground plate insulated from each other. there is

FIG. 1 shows the arrangement of a ground plate 800 and a plurality of contacts 810 included in the internal structure of a receptacle connector conforming to the USB Type-C standard. Further, FIG. 2 is a view of the ground plate 800 and the plurality of contacts 810 shown in FIG. 1 as viewed from the front (in the insertion direction of the mating connector).

As shown in FIGS. 1 and 2, a first group 810U composed of a plurality of contacts 810 arranged on the same plane is provided on the upper surface side of a planar ground plate 800 made of a metal material. A second group 810L composed of a plurality of contacts 810 arranged on the same plane is provided on the lower surface side of the ground plate 800. As shown in FIG.

Each of the first group 810U and the second group 810L is composed of two pairs of high frequency signal contacts 810A for transmitting high frequency signals to and from the mating connector inserted from the distal end side. A normal signal contact pair CP2 composed of a normal signal connector 810B for transmitting a normal frequency signal between the pair CP1 and the mating connector, and a ground contact, a power supply contact, an identification contact, and the like. and a non-signal contact 810C.

In each of the first group 810U and the second group 810L, non-signal contacts 810C are arranged on the left and right sides of each of the two pairs of high-frequency signal contact pairs CP1 and normal signal contact pairs CP2. Further, a normal signal contact pair CP2 is arranged between the two high frequency signal contact pairs CP1. Furthermore, as shown in FIG. 2, the first group 810U and the second group 810L are vertically symmetrical with the ground plate 800 interposed therebetween.

A receptacle connector conforming to the USB Type-C standard is very small, and the distance between the contacts 810 forming the first group 810U and the contacts 810 forming the second group 810L is short. Therefore, crosstalk that occurs between the high-frequency signal contact pair CP1 of the first group 810U and the high-frequency signal contact pair CP1 of the second group 810L becomes a problem. In the receptacle connector conforming to the USB Type-C standard, the ground plate 800 is arranged between the first group 810U and the second group 810L in order to suppress such crosstalk.

However, by placing the ground plate 800 close to the first group 810U and the second group 810L, crosstalk between the two high frequency signal contact pairs CP1 of the first group 810U and It has been found that crosstalk occurs between the two high frequency signal contact pairs CP1 of group 810L. When a high frequency signal flows through one of the high frequency signal contact pairs CP1 of the first group 810U or the second group 810L, the other high frequency signal contact pair CP1 flows through the one high frequency signal contact pair CP1 via the ground plate 800. Under the influence of the high frequency signal, crosstalk occurs in the other high frequency signal contact pair CP1.

In order to address such a problem, Patent Document 1 discloses dividing the ground plate 800 into a plurality of ground plate pieces 800A, 800B, and 800C along the insertion direction of the mating connector, as shown in FIG. ing. The ground plate piece 800A facing one high frequency signal contact pair CP1 of the first group 810U and the second group 810L is separated from the ground plate piece 800C facing the other high frequency signal contact pair CP1. Therefore, the occurrence of crosstalk between the two high-frequency signal contact pairs CP1 of the first group 810U or the second group 810L via the ground plate 800 can be suppressed.

However, when the ground plate 800 is divided into a plurality of ground plate pieces 800A, 800B, and 800C along the insertion direction of the mating connector as shown in FIG. A space S in which the ground plate 800 does not exist is generated between the ground plate piece 800B and between the ground plate piece 800C and the ground plate piece 800B. Since the ground plate 800 bears the bending stress in the plane direction of the internal structure, the bending stress in the plane direction of the internal structure is significantly reduced in the portion where the space S is located. As a result, there is a problem that warpage and bending of the internal structure are likely to occur in the portion where the space S is located.

If the internal structure warps or bends, poor contact between the contacts of the mating connector and the contacts 810 of the receptacle connector is more likely to occur. Therefore, the generation of crosstalk between the two pairs of high-frequency signal contact pairs CP1 of the first group 810U or the second group 810L via the ground plate 800 is suppressed, and the warping and bending of the internal structure is prevented. There is a need to.

A first group 31U and a second group 31L are arranged to face each other via a first ground plate 32L and a second ground plate 32R. The first group 31U and the second group 31L are vertically symmetrically arranged via the first ground plate 32L and the second ground plate 32R. That is, the high frequency signal contacts 31A of the second group 31L face the high frequency signal contacts 31A of the first group 31U, and the normal signal contacts 31B of the second group 31L face the normal signal contacts of the first group 31U. Opposing the contacts 31B, the non-signaling contacts 31C of the second group 31L oppose the non-signaling contacts 31C of the first group 31U.

The number and arrangement of the plurality of high-frequency signal contacts 31A, the plurality of normal signal contacts 31B, and the plurality of non-signal contacts 31C in the first group 31U and the second group 31L are not particularly limited. It is appropriately set according to the standard of the connector.

Each of the first ground plate 32</b>L and the second ground plate 32</b>R is a plate-shaped member made of a metal material embedded in the tongue-shaped portion 332 of the insulator 33 . Each of the first ground plate 32L and the second ground plate 32R includes a flat body portion 321 and a board connection portion 322 extending downward from the base end of the body portion 321 and exposed to the outside of the insulator 33. and have.

The first ground plate 32L and the second ground plate 32R are configured such that the body portions 321 of the first ground plate 32L and the second ground plate 32R are positioned on the ground plane in the insertion direction (Z-axis direction) of the mating connector 100. ) are symmetrical with respect to the center axis of the electrical connector 1 in the width direction (X-axis direction) of the electrical connector 1 . Specifically, as shown in FIG. 11, the first ground plate 32L is arranged on the ground plane in a region in the positive direction of the X-axis from the central axis of the electrical connector 1 in the X-axis direction of the electrical connector 1. The second ground plate 32R is arranged on the ground plane in a region in the negative direction of the X-axis from the center axis of the electrical connector 1 in the X-axis direction.

As shown in FIG. 11, the first ground plate 32L and the second ground plate 32R are spaced apart from each other on the ground plane. Also, the gap between the first ground plate 32L and the second ground plate 32R is filled with an insulator 33 made of an insulating material. Therefore, the first ground plate 32L and the second ground plate 32R are held by the insulator 33 while being insulated from each other.

In addition, in a state where the first ground plate 32L and the second ground plate 32R are held by the insulator 33, a portion of the first ground plate 32L and the second ground plate 32R is the tongue-shaped portion 332 of the insulator 33. It is exposed to the outside through an opening 334 of .

FIG. 12 shows the positional relationship between the first ground plate 32L, the second ground plate 32R, and the plurality of contacts 31. As shown in FIG. 12, in order to clearly show the positional relationship between the first ground plate 32L and the second ground plate 32R and the plurality of contacts 31, the first group 31U composed of the plurality of contacts 31 is omitted. However, as described above, the first group 31U is vertically symmetrically arranged with the second group 31L via the first ground plate 32L and the second ground plate 32R.

As is clear from FIG. 12, on the upper side of the first ground plate 32L, one of the two high-frequency signal contact pairs CP1 of the first group 31U of the plurality of contacts 31 and the one high-frequency signal contact pair CP1 are provided. are located on the left and right sides of the non-signal contacts 31C. On the other hand, on the upper side of the second ground plate 32R, the other of the two pairs of high-frequency signal contact pairs CP1 of the first group 31U of the plurality of contacts 31 and the left and right of the other high-frequency signal contact pair CP1 are arranged. A non-signal contact 31C is located. Similarly, on the lower side of the first ground plate 32L, one of the two pairs of high-frequency signal contact pairs CP1 of the second group 31L of the plurality of contacts 31 and left and right of the one high-frequency signal contact pair CP1 are arranged. A non-signal contact 31C is located. On the other hand, under the second ground plate 32R, the other of the two pairs of high-frequency signal contact pairs CP1 of the second group 31L of the plurality of contacts 31 and the left and right of the other high-frequency signal contact pair CP1 are arranged. A non-signal contact 31C is located.

Thus, in the electrical connector 1 of the present invention, one of the two pairs of high-frequency signal contact pairs CP1 of each of the first group 31U and the second group 31L faces the first ground plate 32L and the two pairs of The second ground plate 32R facing the other of the high-frequency signal contact pair CP1 is spaced apart from each other. Therefore, when a high-frequency signal flows through one of the two pairs of high-frequency signal contact pairs CP1, the other of the two high-frequency signal contact pairs CP1 passes through the first and second ground plates 32L and 32R. It is not affected by the high frequency signal flowing through one of the two high frequency signal contact pairs CP1. Therefore, it is possible to suppress the occurrence of crosstalk between the high-frequency signal contact pairs CP1 of the first group 31U and the second group 31L.

In addition, when the insulator 33 holds the ground plane apart from each other, the first ground plate 32L and the second ground plate 32R at the point where the first ground plate 32L and the second ground plate 32R come closest to each other. The separation distance from the plate 32R is the first ground plate 32L and the second ground plate 32R at the point where the first ground plate 32L and the second ground plate 32R and the plurality of contacts 31 are closest to each other. It is equal to or greater than the separation distance from each of the plurality of contacts 31 . The separation distance between the first ground plate 32L and the second ground plate 32R at the point where the first ground plate 32L and the second ground plate 32R come closest is the distance between the first ground plate 32L and the second ground plate 32R. If the distance between the first ground plate 32L and the second ground plate 32R and each of the plurality of contacts 31 is shorter than the distance at which the ground plate 32R and each of the plurality of contacts 31 are closest to each other, the first ground A pseudo electric circuit may be formed between the plate 32L and the second ground plate 32R, and the crosstalk suppression effect described above may not be obtained.

Next, specific configurations of the first ground plate 32L and the second ground plate 32R will be described in detail. The body portion 321 of each of the first ground plate 32L and the second ground plate 32R has a plane (an upper contact arrangement plane and a lower contact arrangement plane) on which a plurality of contacts 31 are arranged on a tongue-shaped portion 332 of the insulator 33. It is buried so as to be parallel to the plane). Insulators 33 are attached to the body portions 321 of the first ground plate 32L and the second ground plate 32R so as to hold the contacts 31, the first ground plate 32L, and the second ground plate 32R.

For example, in order to position the outermost non-signal contacts 31C of the first group 31U and the second group 31L composed of a plurality of contacts 31, two positioning holes 323 and tie-bar cut holes 324 are formed. Positioning pins are inserted through the tie-bar cut hole 324 and the impedance adjusting hole 325 to position the high-frequency signal contact 31A. A positioning pin is inserted through the gap between the ground plate 32L and the second ground plate 32R. The number, position, and shape of the positioning holes 323 in the main body portion 321 are not particularly limited, and are appropriately set as necessary when the insulator 33 is insert-molded.

The tie-bar cut holes 324 are formed by punching out the connection portions of the plurality of contacts 31 connected to each other through the connection portions when the insulator 33 is insert-molded, and executing the tie-bar cut for separating the plurality of contacts 31 from each other. Therefore, it is formed in the main body portion 321 . When the insulator 33 is insert-molded, the plurality of contacts 31 are positioned by the positioning pins as described above. are preferably held connected to each other at the root portion. Therefore, the plurality of contacts 31 are connected to each other by the connecting portion provided at the root portion when the insulator 33 is insert-molded. In the illustrated form, of the plurality of contacts 31 that constitute the first group 31U and the second group 31L, two high-frequency signal contacts 31A that constitute the high-frequency signal contact pair CP1 and left and right contacts of the high-frequency signal contact pair CP1. The two non-signal contacts 31C positioned are connected to each other by a connecting portion, and furthermore, two normal signal contacts 31B constituting a normal signal contact pair CP2 and two non-signal contacts 31B positioned to the left and right of the normal signal contact pair CP2. Contacts 31C are connected to each other by connecting portions. Therefore, the plurality of contacts 31 are composed of three contact parts in which four contacts 31 are connected to each other when the insulator 33 is insert-molded.

After the insulator 33 is insert-molded, the tie-bar cutting is performed to punch out the connecting portions of the four contacts 31 connected to each other of the three contact parts, and to separate the plurality of contacts 31 from each other. The number, position, and shape of the tie-bar cut holes 324 are not particularly limited, and are appropriately set as necessary when cutting the tie-bars after the insulator 33 is insert-molded.

The impedance adjustment holes 325 are formed at positions corresponding to the high-frequency signal contacts 31A of the body portion 321 in order to adjust the impedance of each of the high-frequency signal contacts 31A. The number, position and shape of the impedance adjustment holes 325 are not particularly limited, and are appropriately set according to the required impedance characteristics of the high frequency signal contact 31A.

11 and 12, both the first ground plate 32L and the second ground plate 32R have one or more extensions extending from one side to the other on the ground plane. Specifically, the first ground plate 32L includes a distal end extending portion 326A extending from the distal end side of the main body portion 321 toward the second ground plate 32R, and a mating connector insertion direction (Z-axis) of the main body portion 321. direction), a central extending portion 326B extending from the central portion toward the second ground plate 32R, and a proximal extending portion 326C extending from the proximal side of the main body portion 321 toward the second ground plate 32R. I have. Similarly, the second ground plate 32R includes a leading end extending portion 326A extending from the leading end side of the main body portion 321 toward the first ground plate 32L, and an insertion direction (Z-axis direction) of the mating connector of the main body portion 321. A central extending portion 326B extending from the central portion toward the first ground plate 32L, and a proximal extending portion 326C extending from the proximal side of the main body portion 321 toward the first ground plate 32L. there is

In this way, both the first ground plate 32L and the second ground plate 32R are provided with extending portions extending from one side to the other side on the ground plane. direction), it is possible to prevent the occurrence of an area where the first ground plate 32L or the second ground plate 32R does not exist. Since the first ground plate 32L and the second ground plate 32R bear the stress in the plane direction of the internal structure 3, such a configuration results in a region where the stress in the plane direction of the internal structure 3 is significantly reduced. can be reduced or the occurrence of such a region can be prevented. As a result, it is possible to suppress the occurrence of warping or bending of the internal structural body 3, thereby preventing poor contact between the mating connector 100 and the electrical connector 1 when the mating connector 100 is inserted into the electrical connector 1 from the distal end side. can be suppressed.

In particular, in the form shown in FIGS. 11 and 12, the central extension portion 326B of the first ground plate 32L and the central extension portion 326B of the second ground plate 32R are arranged in the insertion direction (Z-axis direction) of the mating connector, At least part of the tip side overlaps. Therefore, there is no region where the first ground plate 32L or the second ground plate 32R does not exist when viewed from the insertion direction (Z-axis direction) of the mating connector. Due to such a configuration, in the illustrated electrical connector 1, there is no region where the stress in the plane direction of the internal structure 3 is remarkably reduced. Therefore, warping and bending of the internal structure 3 can be suppressed more reliably.

In the insertion direction (Z-axis direction) of the mating connector, the width W (the width of the electrical connector 1 The length in the direction (X-axis direction) is preferably 0.25 mm or more, more preferably 0.5 mm or more. If the width W is less than the above value, the effect of preventing the stress in the plane direction of the internal structure 3 from decreasing cannot be sufficiently exhibited.

11 and 12, the points where the first ground plate 32L and the second ground plate 32R are closest to each other are the leading end extending portion 326A of the first ground plate 32L and the second ground plate. 32R, between the center extension 326B of the first ground plate 32L and the main body portion 321 of the second ground plate 32R, between the center extension 326B of the second ground plate 32R and the first ground plate 32R. or between the base end extending portion 326C of the first ground plate 32L and the base end extending portion 326C of the second ground plate 32R. The separation distance between the first ground plate 32L and the second ground plate 32R at the point where the first ground plate 32L and the second ground plate 32R are closest to each other is, as described above, the first ground plate 32L. and the separation distance between the first ground plate 32L and the second ground plate 32R and each of the plurality of contacts 31 at the point where the second ground plate 32R and each of the plurality of contacts 31 are closest to each other there is

11 and 12, both the first ground plate 32L and the second ground plate 32R are provided with extending portions extending from one side to the other side, but the present invention is not limited to this. Not limited. For example, it is within the scope of the present invention that only one of the first gland plate 32L and the second gland plate 32R has an extension extending from one to the other. For example, it is within the scope of the invention that only the first gland plate 32L includes at least one of the distal extension 326A, the central extension 326B, and the proximal extension 326C. In this case, it is impossible to completely prevent the occurrence of an area where the first ground plate 32L or the second ground plate 32R does not exist when viewed from the insertion direction (Z-axis direction) of the mating connector. Such areas can be reduced. Therefore, it is possible to reduce the region where the stress in the plane direction of the internal structure 3 is remarkably reduced, and it is possible to suppress the occurrence of warping and bending of the internal structure 3 .

The number, position, and shape of the extending portions provided in both the first ground plate 32L and the second ground plate 32R can be appropriately set according to the required stress in the plane direction of the internal structure 3 . For example, FIG. 13 shows multiple variations of the first ground plate 32L and the second ground plate 32R.

FIG. 13(a) shows one modification of the first ground plate 32L and the second ground plate 32R. Compared with the configuration shown in FIG. 11, in the modification shown in FIG. The width in the Z-axis direction of 326B is increased. In this case, in the insertion direction (Z-axis direction) of the mating connector, the center extending portion 326B of the second ground plate 32R and the distal extending portion 326A and the proximal extending portion 326C of the first ground plate 32L overlap. ing. In the modification shown in FIG. 13(a), compared with the configuration shown in FIG. 32L and the central extension 326B of the second ground plate 32R occupy an increased proportion of the linear region connecting the gap with the proximal extension 326C of the second ground plate 32R. Therefore, the gap between the leading end extending portions 326A of the first ground plate 32L and the second ground plate 32R and the gap between the base end extending portions 326C of the first ground plate 32L and the second ground plate 32R It is possible to more effectively prevent a decrease in the stress in the plane direction of the internal structure 3 in the linear region connecting the .

In the modification shown in FIG. 13(b), the second ground plate 32R has two central extensions 326B extending in parallel toward the first ground plate 32L, and the direction of insertion of the mating connector (Z-axis direction), the central extension 326B of the first gland plate 32L and the two central extensions 326B of the second gland plate 32R alternate. In the modification shown in FIG. 13(b) as well, compared with the configuration shown in FIG. The proportion of the central extension 326B of the second ground plate 32R occupied in the linear region connecting the gap between the plate 32L and the proximal extension 326C of the second ground plate 32R is increased.

In the modification shown in FIG. 13(c), the tip portion of the central extension portion 326B of the first ground plate 32L is bent in the negative direction of the Z axis, and the central extension portion of the second ground plate 32R is bent toward the negative direction of the Z axis. The tip portion of 326B is bent toward the positive direction of the Z-axis. Therefore, in the modification shown in FIG. 13C, the center extending portion 326B of the first ground plate 32L and the center extending portion 326B of the second ground plate 32R are aligned in the insertion direction (Z-axis direction) of the mating connector 100. Not only that, but also in the width direction (X-axis direction) of the electrical connector 1 perpendicular to the insertion direction of the mating connector 100 . In the modification shown in FIG. 13(c) as well, compared to the configuration shown in FIG. Proportion of the center extending portion 326B of the first ground plate 32L and the second ground plate 32R in the linear region connecting the gap between the plate 32L and the base end extending portion 326C of the second ground plate 32R is increasing.

In the modification shown in FIG. 13D, the width in the X-axis direction of the proximal extension portion 326C of the first ground plate 32L is reduced, and the width in the X-axis direction of the proximal extension portion 326C of the second ground plate 32R is reduced. width is increased. Therefore, the gap between the leading end extending portions 326A of the first ground plate 32L and the second ground plate 32R and the gap between the base end extending portions 326C of the first ground plate 32L and the second ground plate 32R are Not collinear. The gap between the leading end extending portions 326A of the first ground plate 32L and the second ground plate 32R and the gap between the base end extending portions 326C of the first ground plate 32L and the second ground plate 32R are on the same straight line. If it is positioned in the shape of a straight line, the stress in the plane direction of the internal structure 3 will be reduced in the linear region. On the other hand, in the modification shown in FIG. 13(d), the gap between the leading end extending portions 326A of the first ground plate 32L and the second ground plate 32R and the gap between the first ground plate 32L and the second ground plate 32R Since the gap with respect to the base end extending portion 326C is not located on the same straight line, it is possible to prevent the occurrence of a region where the stress in the plane direction of the internal structure 3 is reduced.

The modifications shown in FIGS. 13A to 13C have the configuration shown in FIG. This is an improved configuration for increasing the ratio of the extending portions of the first ground plate 32L and the second ground plate 32R in the area of . The modification shown in FIG. 13(d) has a gap between the leading end extending portions 326A of the first gland plate 32L and the second gland plate 32R, and the base of the first gland plate 32L and the second gland plate 32R. This is an improved configuration for more effectively preventing a decrease in the stress in the plane direction of the internal structural body 3 in the linear region connecting the end extending portion 326C and the gap.

Even when the modification of the first ground plate 32L and the second ground plate 32R detailed with reference to FIG. 13 is used, when viewed from the insertion direction (Z-axis direction) of the mating connector, , the occurrence of regions where the first ground plate 32L or the second ground plate 32R does not exist can be prevented. Therefore, it is possible to prevent the occurrence of a region where the stress in the plane direction of the internal structure 3 is remarkably reduced.

At the same time, the shell contact portion 22 of the shell 2 of the electrical connector 1 is in contact with the outer periphery of the shell 110 of the mating connector 100, and the electrical connector is exposed to the outside through the opening 334 of the tongue-shaped portion 332 of the insulator 33. A part of the first ground plate 32L and the second ground plate 32R of one contact the ground terminal of the mating connector 100, so that the mating connector 100 and the electrical connector 1 have the same ground potential. Also, the tip of the shell 110 of the mating connector 100 comes into contact with the shell stopper 23 of the shell 2 of the electrical connector 1, and the insertion operation of the mating connector 100 is restricted.
