[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-075315 Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure provides a connector system that is effective in achieving both reliable signal transmission and miniaturization. [Means for solving the problem]

[0005] A connector system according to one aspect of the present disclosure comprises a connector having an insulating housing, conductive contacts held in the insulating housing, and a conductive shell held in the insulating housing so as to be arranged around the contacts; a mating connector having a mating insulating housing that mates with the insulating housing along a mating direction, conductive mating contacts that are held in the mating insulating housing and come into contact with the contacts when the mating insulating housing is mated to the insulating housing, and a conductive mating shell that is held in the mating insulating housing and that cooperates with the shell to form an enclosure that surrounds the contacts and the mating contacts around an axis along the mating direction when the mating insulating housing is mated to the insulating housing, wherein, in the circumferential direction around the axis, the length of the portion where the shell forms the enclosure without overlapping with the mating shell and the length of the portion where the mating shell forms the enclosure without overlapping with the shell are each longer than the total length of the portion where the shell and the mating shell overlap to form the enclosure.

[0006] It is possible to form an enclosure that surrounds the contact and the mating contact while reducing the overlapping portion between the shell and the mating shell, which is therefore effective in achieving both reliable signal transmission and miniaturization.

[0007] The connector further has conductive second contacts held in the insulating housing so as to be aligned with the contacts along an arrangement direction perpendicular to the mating direction, and a conductive second shell held in the insulating housing so as to be arranged around the second contacts. The mating connector further has conductive mating second contacts held in the mating insulating housing so as to be aligned with the mating contacts along the arrangement direction, and which come into contact with the second contacts when the mating insulating housing is mated to the insulating housing, and a conductive mating second shell held in the mating insulating housing and which, when the mating insulating housing is mated to the insulating housing, cooperates with the second shell to form a second enclosure that surrounds the second contacts and the mating second contacts around an axis along the mating direction. In the circumferential direction around the axis, the length of each of the portion where the second shell forms the second enclosure without overlapping with the mating second shell and the portion where the mating second shell forms the second enclosure without overlapping with the second shell may be longer than the total length of the portion where the second shell and the mating second shell overlap to form the second enclosure. The second enclosure can be configured with the second contact and the mating second contact while reducing the overlapping portion between the second shell and the mating second shell, which is more effective in achieving both reliable signal transmission and compactness.

[0008] The contact and the second contact may be electrically connected to a first signal line and a second signal line on the circuit board, and the mating contact and the mating second contact may be electrically connected to a first signal conductor and a second signal conductor of one or more cables. This is effective for miniaturizing a device in which the circuit board is mounted.

[0009] The insulating housing may have a surface facing the circuit board, and the arrangement direction and the mating direction may be parallel to the surface. This is effective in reducing the size of the connector relative to the circuit board.

[0010] The shell may include a contact portion that comes into contact with the mating shell at a portion where the shell and the mating shell overlap to form an enclosure. The contact between the shell and the mating shell can further improve the reliability of signal transmission.

[0011] The enclosure may surround the contact and the mating contact without interruption. The contact between the shell and the mating shell can further improve the reliability of signal transmission.

[0012] The length of the portion of the shell that does not overlap with the mating shell and forms the enclosure, and the length of the portion of the shell that does not overlap with the mating shell and forms the enclosure, may each account for ¼ or more of the entire circumference of the enclosure, which is even more effective for miniaturization.

[0013] The portion of the shell that does not overlap with the mating shell and forms the enclosure may include a pair of side portions that face each other in an opposing direction perpendicular to the fitting direction, and a base portion that connects the pair of side portions, and the portion of the mating shell that does not overlap with the shell and forms the enclosure may also include a mating base portion that faces the base portion. This is further effective for miniaturization.

[0014] The shell may have a pair of overlapping portions connected to the pair of side portions, respectively, and the mating shell may have a pair of mating overlapping portions facing each other in the opposing direction, overlapping the pair of overlapping portions from the inside, and maintained in contact with the shell. This is even more effective in achieving both reliable signal transmission and compactness.

[0015] The shell may overlap with the mating shell along the circumferential direction around the axis, which is more effective for miniaturization.

[0016] The shell may have a wall portion with a slit formed along the mating direction, and the mating shell may have a mating wall portion that intersects the wall portion and fits into the slit, thereby maintaining contact with the shell along the circumferential direction. This is even more effective in achieving both reliable signal transmission and compactness.

[0017] The mating shell may further have a mating cross wall portion that crosses the mating wall portion, and a mating slit that extends in the mating direction may be formed in the mating cross wall portion, and the shell may have a cross wall portion that crosses the mating cross wall portion and fits into the mating slit, thereby maintaining contact with the mating shell along the circumferential direction. This is even more effective in achieving both reliable signal transmission and compactness.

[0018] A connector according to another aspect of the present disclosure is a connector that is connected to a mating connector having a mating insulating housing, conductive mating contacts held in the mating insulating housing, and a conductive mating shell held in the mating insulating housing so as to be arranged around the mating contacts, and comprises: an insulating housing that mates with the mating insulating housing along a mating direction; conductive contacts that are held in the insulating housing and come into contact with the mating contacts when the insulating housing is mated with the mating insulating housing; and a conductive shell that is held in the insulating housing and, when the insulating housing is mated with the mating insulating housing, cooperates with the mating shell to form an enclosure that surrounds the contacts and the mating contacts around an axis along the mating direction, and in the circumferential direction around the axis, the length of each of the portion where the shell forms the enclosure without overlapping with the mating shell and the portion where the mating shell forms the enclosure without overlapping with the shell is longer than the total length of the portion where the shell and the mating shell overlap to form the enclosure.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, the embodiments will be described in detail with reference to the drawings. In the description, the same elements or elements having the same functions are denoted by the same reference numerals, and redundant description will be omitted.

[0022] [Connector System] The connector system 1 shown in Figures 1 and 2 is used to connect a circuit board 10 (shown in Figure 3) to multiple cables 20 in applications requiring low-profile and low-frequency signal transmission. One example of such an application is an information processing system in which signals are transmitted on the circuit board 10 using multiple cables 20 instead of printed wiring on the circuit board 10. By using shielded cables for each of the multiple cables 20, signals can be transmitted with higher signal transmission characteristics than printed wiring. Signal transmission characteristics refer to less signal degradation during signal transmission, and high signal transmission characteristics refer to less signal degradation during signal transmission. Specific examples of signal degradation include noise contamination due to crosstalk and signal attenuation.

[0023] In order to further improve the signal transmission characteristics of the multiple cables 20, it is necessary to position the connection points between the circuit board 10 and the multiple cables 20 close to the circuit elements (e.g., processors) on the circuit board 10. To position the connection points between the circuit board 10 and the multiple cables 20 close to the circuit elements, it is necessary to avoid interference with heat sinks and the like provided on the circuit elements. For this reason, it is necessary to reduce the height of the connector system 1.

[0024] The connector system 1 includes a connector 2 and a connector 3. The connector 2 is, for example, a receptacle connector and is connected to a circuit board 10. The connector 3 is, for example, a plug connector and is connected to a plurality of cables 20. The connector 3 can be connected to the connector 2. By connecting the connector 3 to the connector 2, the plurality of cables 20 are electrically connected to the circuit board 10. The connectors 2 and 3 are mated with each other along a mating direction D12 parallel to the circuit board 10. Hereinafter, the connector 3 may be referred to as the "mating connector" for the connector 2, but this does not necessarily mean that only the connector 3 corresponds to the "mating connector," and the connector 2 is the "mating connector" for the connector 3.

[0025] The connector 2 includes a plurality of contacts 200, a plurality of shells 300, and an insulating housing 100. The plurality of contacts 200 are held in the insulating housing 100 so as to be aligned along an arrangement direction D11 that is parallel to the main surface of the circuit board 10 and perpendicular to the mating direction D12. Each of the plurality of contacts 200 is electrically connected to the circuit board 10 and comes into contact with a signal contact of the mating connector (connector 3). Each of the plurality of shells 300 is held in the insulating housing 100 so as to be arranged around at least one contact 200. For example, each of the plurality of shells 300 is held in the insulating housing 100 so as to surround at least one contact 200 around an axis along the mating direction D12.

[0026] The multiple contacts 200 transmit multiple types of signals. Multiple shells 300 may be provided for each of the multiple types of signals. In this case, only one type of signal is transmitted in the area surrounded by each of the multiple shells 300, and other signals are not transmitted. As an example, each of the multiple contacts 200 may transmit one type of signal referenced to ground potential. In this case, multiple shells 300 are provided for each of the multiple contacts 200. Each of the multiple shells 300 surrounds only one contact 200 and does not surround the other contacts 200. The multiple contacts 200 may include multiple pairs of contacts 200, each transmitting multiple types of differential signals. In this case, multiple shells 300 are provided for each of the multiple pairs of contacts 200. Each of the multiple shells 300 surrounds only one pair of contacts 200 and does not surround the other contacts 200.

[0027] The insulating housing 100 integrally holds the plurality of contacts 200 and the plurality of shells 300. The insulating housing 100 keeps the plurality of contacts 200 insulated from one another, keeps the plurality of shells 300 insulated from one another, and keeps the plurality of contacts 200 and the plurality of shells 300 insulated from one another.

[0028] 1 and 10, the connector 3 includes a base unit 500 and a plurality of shells 600. The base unit 500 includes a connector base 510, a plurality of insulating housings 520, and a plurality of conductive contacts 530. The connector base 510 extends along an arrangement direction D11 (D21). The plurality of insulating housings 520 are aligned along the arrangement direction D11 and protrude in the same direction from the connector base 510 along a mating direction D12 (D22).

[0029] The contacts 530 are held in the insulating housings 520 so as to be aligned along the arrangement direction D11. Each of the contacts 530 is electrically connected to one of the cables 20 and comes into contact with a contact 200 of a mating connector (connector 2). Each of the insulating housings 520 holds at least one contact 530.

[0030] The multiple contacts 530 may transmit the multiple types of signals described above, and multiple insulating housings 520 may be provided for each of the multiple types of signals. In this case, only one type of signal is transmitted through the multiple insulating housings 520, and no other signals are transmitted. As an example, each of the multiple contacts 530 may transmit one type of signal referenced to ground potential. In this case, multiple insulating housings 520 are provided for each of the multiple contacts 530. Each of the multiple insulating housings 520 holds only one contact 530 and does not hold any other contacts 530. The multiple contacts 530 may include multiple pairs of contacts 530, each transmitting multiple types of differential signals. In this case, multiple insulating housings 520 are provided for each of the multiple pairs of contacts 530. Each of the multiple insulating housings 520 holds only one pair of contacts 530 and does not hold any other contacts 530.

[0031] The multiple shells 600 correspond to the multiple insulating housings 520, respectively. Each of the multiple shells 600 surrounds the corresponding insulating housing 520 around an axis along the fitting direction D12 (D22).

[0032] The insulating housings 520 correspond to the shells 300, respectively. As shown in FIGS. 3 and 4 , each of the insulating housings 520 is inserted into the corresponding shell 300 along the mating direction D12. Each of the shells 600 is mated with the corresponding shell 300 along the mating direction D12. Each of the contacts 530 contacts a corresponding contact 200 in the corresponding shell 300. This electrically connects the cables 20 to the circuit board 10.

[0033] According to this connector system 1, by providing individual shells 300 for the multiple contacts 200, it is possible to individually optimize the relationship between the contacts 200 and the shells 300. Furthermore, the shells 300 surround the contacts 200 around an axis along the mating direction D12 parallel to the circuit board 10. This restricts the mating direction of the connector 3 to the connector 2 to a direction parallel to the circuit board 10. This makes it possible to reduce the height of the connection formed by the connectors 2 and 3 (reducing the height relative to the surface of the circuit board 10). This is therefore effective in achieving both improved signal transmission characteristics and a reduced height.

[0034] The reduced height makes it possible to avoid interference with the heat sink 12 and place the connector 2 near the circuit element 11, as shown in Figures 3 and 4, for example, thereby further improving the signal transmission characteristics.

[0035] Each of the multiple shells 300 may complement the surrounding of the insulating housing 520 by the corresponding shell 600. For example, the shell 300 may surround a portion of the periphery of the insulating housing 520 that is not surrounded by the shell 600. This reduces the overlap between the shell 600 and the shell 300, thereby enabling a further reduction in height.

[0036] The configurations of the connectors 2 and 3 will be described in more detail below.

[0037] [First connector] In describing the connector 2, for convenience, the direction toward the surface of the circuit board will be referred to as "downward," and the direction away from the surface of the circuit board will be referred to as "upward." Fig. 5 is a perspective view of the connector 2 as seen from below, and Fig. 6 is an exploded perspective view of the connector 2 in Fig. 5. As shown in Fig. 5, the connector 2 has an insulating housing 100, a plurality of conductive contacts 200, and a plurality of conductive shells 300.

[0038] 6 and 7, the insulating housing 100 has an opposing surface 101, a recessed surface 102, and a plurality of protrusions 110. The opposing surface 101 faces the circuit board 10. The arrangement direction D11 and the fitting direction D12 are parallel to the opposing surface 101. With the opposing surface 101 facing the circuit board 10, the recessed surface 102 faces the circuit board 10 at a position separated from the circuit board 10. The plurality of protrusions 110 are aligned along the arrangement direction D11 parallel to the opposing surface 101, and each protrudes from the recessed surface 102.

[0039] The multiple protrusions 110 correspond to the multiple shells 300, respectively. Each of the multiple shells 300 is held by a corresponding protrusion 110. At least one contact 200 surrounded by each of the multiple shells 300 is also held by the protrusion 110. For example, a pair of contacts 200 surrounded by each of the multiple shells 300 are held by the protrusion 110 so as to be aligned along the arrangement direction D11. The insulating housing 100 is formed by molding a resin material or the like.

[0040] One protrusion 110, the corresponding shell 300, and a pair of contacts 200 constitute one set of signal transmission parts TP1. The connector 2 includes multiple sets of signal transmission parts TP1 corresponding to the multiple protrusions 110, respectively. The multiple sets of signal transmission parts TP1 are arranged along the arrangement direction D11 and transmit the multiple types of signals described above, respectively. Below, the configuration of the first and second sets of signal transmission parts TP1 from the left side of the figure will be illustrated in more detail as representative of the multiple sets of signal transmission parts TP1.

[0041] Although the configuration of the multiple sets of signal transmission parts TP1 is common, for ease of explanation, the convex part 110, contact 200 and shell 300 belonging to the first signal transmission part TP1 from the left in the figure will be referred to as the first convex part 110A, first contact 200A and first shell 300A, and the convex part 110, contact 200 and shell 300 belonging to the second signal transmission part TP1 from the left in the figure will be referred to as the second convex part 110B, second contact 200B and second shell 300B to distinguish them from one another.

[0042] 7 , the first contacts 200A and the second contacts 200B are held in the insulating housing 100 so as to be aligned along the arrangement direction D11. The first contacts 200A and the second contacts 200B are electrically connected to a pair of signal lines 13 on the circuit board 10. The "pairs of signal lines 13" to which the first contacts 200A and the second contacts 200B are respectively connected transmit different signals. When the first convex portion 110A includes a pair of first contacts 200A and the second convex portion 110B includes a pair of second contacts 200B, for example, the pair of first contacts 200A is held by the first convex portion 110A so as to be aligned along the arrangement direction D11, and the pair of second contacts 200B is held by the second convex portion 110B so as to be aligned along the arrangement direction D11, and the pair of first contacts 200A and the pair of second contacts 200B are aligned along the arrangement direction D11 in accordance with the arrangement of the first convex portion 110A and the second convex portion 110B.

[0043] The pair of first contacts 200A are electrically connected to a pair of signal lines 13A that transmit a first differential signal on the circuit board 10. The pair of second contacts 200B are electrically connected to a pair of signal lines 13B that transmit a second differential signal different from the first differential signal on the circuit board 10.

[0044] Each of the pair of first contacts 200A has a connecting portion 201 (first connecting portion) and a contact portion 202 (first contact portion). The connecting portion 201 is electrically connected to the circuit board 10. For example, the connecting portion 201 is connected to a conductive signal terminal formed on the circuit board 10 by soldering or the like. The contact portion 202 protrudes from the connecting portion 201 along a mating direction D12 that is parallel to the opposing surface 101 and perpendicular to the arrangement direction D11. For convenience of explanation, the protruding direction of the contact portion 202 relative to the connecting portion 201 will be referred to as the "forward" direction, and the opposite direction will be referred to as the "rearward" direction. The first contact 200A is bent in a crank shape between the connecting portion 201 and the contact portion 202 so that the contact portion 202 is positioned away from the circuit board 10. The first contact 200A is formed, for example, by punching and bending a thin metal plate.

[0045] Each of the pair of second contacts 200B is configured similarly to the first contact 200A, and includes a connecting portion 201 (second connecting portion) and a contact portion 202 (second contact The connecting portion 201 of the second contact 200B is connected by soldering or the like to a conductive signal terminal formed on the circuit board 10, separate from the signal terminal to which the connecting portion 201 of the first contact 200A is connected.

[0046] The first shell 300A is held in the insulating housing 100 so as to be disposed around the pair of first contacts 200A. For example, the first shell 300A is held in the insulating housing 100 so as to surround the pair of first contacts 200A around an axis along the mating direction D12, and is electrically connected to the circuit board 10 with the opposing surface 101 facing the circuit board 10.

[0047] In the mating direction D12, the first shell 300A may partially surround the pair of first contacts 200A. For example, the first shell 300A surrounds at least the contact portions 202 of the pair of first contacts 200A.

[0048] Within the first shell 300A, no signals other than the one type of signal transmitted by at least one first contact 200A are transmitted. This one type of signal is the only signal transmitted within the first shell 300A. For example, within the first shell 300A, only the first differential signal is transmitted, and no other signals are transmitted. The first shell 300A surrounds only the pair of first contacts 200A, and does not surround the other contacts 200A.

[0049] The shape surrounding the pair of first contacts 200A is not particularly limited. The first shell 300A may surround the pair of first contacts 200A in a circular shape, or may surround the pair of first contacts 200A in a polygonal shape. As an example, the first shell 300A may surround the first contacts 200A in a rectangular shape. For example, the first shell 300A has a pair of sidewall portions 310 (first sidewall portions) and a base portion 320 (first base portion) (see FIG. 8).

[0050] The pair of side wall portions 310 face each other along the arrangement direction D11. The contact portions 202 of the pair of first contacts 200A are located between the pair of side wall portions 310. The base portion 320 extends parallel to the opposing surface 101 and connects the pair of side wall portions 310. With the opposing surface 101 facing the circuit board 10, the base portion 320 may be located between the contact portions 202 and the circuit board 10.

[0051] As shown in FIG. 6, a receiving space IS (first receiving space) is formed between the pair of sidewall portions 310. A mating first housing (one of the plurality of insulating housings 520) of a mating connector (connector 3) is inserted into the receiving space IS along the mating direction D12. A mating shell (shell 600A) of the mating connector is mated with the first shell 300A, and a mating signal contact (contact 530A) held in the mating first housing comes into contact with the contact portion 202 of the first contact 200A (see FIG. 4). For example, the pair of contacts 530A come into contact with the contact portions 202 of the pair of first contacts 200A, respectively.

[0052] 8, the first shell 300A may further have a pair of protruding portions 340 (first protruding portions) that protrude rearward from the pair of side wall portions 310. The connecting portions 201 of the pair of first contacts 200A are located between the pair of protruding portions 340.

[0053] The first shell 300A may further have a pair of shell connecting portions 341 (first shell connecting portions) formed on the pair of overhanging portions 340, respectively, so as to be electrically connected to the circuit board 10 when the opposing surface 101 faces the circuit board 10. For example, each of the pair of shell connecting portions 341 is formed on the lower edge of the corresponding overhanging portion 340, and is connected by soldering or the like to a conductive ground terminal formed on the circuit board 10 separately from the above-mentioned signal terminal. In the circuit board 10, a ground potential is applied to the ground terminal. The same applies to the ground terminals to which other portions of the shell connecting portions 341 are connected.

[0054] The first shell 300A may further include an anchor portion 350 (first anchor portion) and an intermediate connection portion 360 (first intermediate connection portion) (see FIG. 9 ). The anchor portion 350 protrudes rearward from the base portion 320 and is held by the first protrusion 110A. The intermediate connection portion 360 is formed on the base portion 320 so as to be electrically connected to the circuit board 10 when the facing surface 101 faces the circuit board 10. For example, the intermediate connection portion 360 is formed at the rear end of the anchor portion 350 and protrudes from the rear end of the anchor portion 350 in a direction away from the receding surface 102. As an example, the intermediate connection portion 360 protrudes rearward and downward from the rear end of the anchor portion 350 and is connected to a ground terminal formed on the circuit board 10 by soldering or the like.

[0055] The first shell 300A is formed by, for example, stamping and forming a metal sheet.

[0056] The second shell 300B is held in the insulating housing 100 so as to be disposed around the pair of second contacts 200B. The second shell 300B is held in the insulating housing 100 so as to surround the pair of second contacts 200B around an axis along the mating direction D12, and is electrically connected to the circuit board 10 with the opposing surface 101 facing the circuit board 10. For example, the second shell 300B surrounds the contact portions 202 of at least one pair of second contacts 200B. No signals are transmitted within the second shell 300B other than the one type of signal transmitted by at least one second contact 200B. This one type of signal is the only signal transmitted within the second shell 300B. For example, only the second differential signal is transmitted within the second shell 300B, and no other signals are transmitted within the second shell 300B. The second shell 300B surrounds only the pair of second contacts 200B, and does not surround the other contacts 200B.

[0057] The second shell 300B is configured similarly to the first shell 300A, and has a pair of side walls 310 (second side walls) and a base 320 (second base). The contact portions 202 of the pair of second contacts 200B are located between the pair of side walls 310.

[0058] A receiving space IS (second receiving space) is formed between the pair of sidewall portions 310. A mating second housing (one of the plurality of insulating housings 520) of a mating connector (connector 3) is inserted into the receiving space IS along the mating direction D12. A mating shell (shell 600B) surrounding the mating second housing is mated with the second shell 300B, and mating signal contacts (contacts 530B) held in the mating second housing come into contact with the contact portions 202 of the second contacts 200B (see FIG. 4). For example, the pair of contacts 530B each come into contact with the contact portions 202 of the pair of second contacts 200B.

[0059] Similar to the first shell 300A, the second shell 300B may further have a pair of overhanging portions 340 (second overhanging portions) and a pair of shell connecting portions 341. The connecting portions 201 of the pair of second contacts 200B are located between the pair of overhanging portions 340. Similar to the pair of shell connecting portions 341 of the first shell 300A, the pair of shell connecting portions 341 of the second shell 300B are connected to ground terminals formed on the circuit board 10 by soldering or the like.

[0060] Like the first shell 300A, the second shell 300B may further include an anchor portion 350 and an intermediate connection portion 360. The anchor portion 350 protrudes rearward from the base portion 320 and is held by the second protrusion 110B. The intermediate connection portion 360 is connected to a ground terminal formed on the circuit board 10 by soldering or the like.

[0061] As shown in FIG. 7 , the first protrusion 110A protrudes from the recessed surface 102 and is positioned between a pair of overhanging portions 340 of the first shell 300A to hold the pair of first contacts 200A and the first shell 300A. For example, the first protrusion 110A has a pair of contact-holding holes 111 (positioned above the first protrusion 110A) and an anchor hole 112. The pair of contact-holding holes 111 are aligned along the arrangement direction D11 and each penetrates the first protrusion 110A along the mating direction D12. The contact portions 202 of the pair of first contacts 200A are inserted into the pair of contact-holding holes 111 from the rear. Ends of the contact portions 202 of the pair of first contacts 200A protrude forward from the first protrusion 110A and are surrounded by the first shell 300A. The anchor hole 112 is positioned below the pair of contact-holding holes 111 and penetrates the first protrusion 110A along the mating direction D12. The anchor portion 350 of the first shell 300A is inserted into the anchor hole 112 from the front.

[0062] The first protrusion 110A may have a slit 113 (first slit) formed therein. The slit 113 allows displacement of the intermediate connector 360 along the fitting direction D12. For example, the slit 113 is formed along the fitting direction D12 over the entire length of the lower part of the anchor hole 112, and the intermediate connector 360 is disposed within the slit 113. Because the slit 113 extends along the fitting direction D12, displacement of the intermediate connector 360 along the fitting direction D12 is allowed.

[0063] The insulating housing 100 may further include a first support portion 114A. The first support portion 114A protrudes forward from the first protrusion 110A and is located between the contact portion 202 and the base portion 320. For example, the first support portion 114A protrudes forward from the first protrusion 110A between the pair of contact holding holes 111 and the anchor hole 112.

[0064] The second protrusion 110B protrudes from the receding surface 102 and is positioned between a pair of overhanging portions 340 of the second shell 300B to hold the pair of second contacts 200B and the second shell 300B. For example, similar to the first protrusion 110A, the second protrusion 110B has a pair of contact holding holes 111 (positioned above the second protrusion 110B) and an anchor hole 112. The contact portions 202 of the pair of second contacts 200B are inserted into the pair of contact holding holes 111 from the rear, respectively. Ends of the contact portions 202 of the pair of second contacts 200B protrude forward from the second protrusion 110B and are surrounded by the second shell 300B. The anchor portion 350 of the second shell 300B is inserted into the anchor hole 112 from the front. Similar to the first protrusion 110A, the second protrusion 110B may have a slit 113 (second slit). In the slit 113, the intermediate connection portion 360 of the second shell 300B is disposed.

[0065] The insulating housing 100 may further include a second support portion 114B similar to the first support portion 114A. The second support portion 114B protrudes forward from the second protrusion 110B and is located between the contact portion 202 and the base portion 320. For example, the second support portion 114B protrudes forward from the second protrusion 110B between the pair of contact holding holes 111 and the anchor hole 112.

[0066] 5 and 6, the connector 2 may further include a conductive outer shell 400. The insulating housing 100 has a rear surface 103 of the opposing surface 101, and the outer shell 400 covers the rear surface 103.

[0067] For example, the outer shell 400 has a main plate portion 410, a pair of outer side walls 420, and a pair of anchor portions 430, and is formed by punching and bending a thin metal plate material. The main plate portion 410 extends so as to cover at least a portion of the rear surface 103. The pair of outer side walls 420 are provided at both ends of the main plate portion 410 in the arrangement direction D11. For example, the pair of outer side walls 420 are bent downward with respect to the main plate portion 410 at both ends of the main plate portion 410 and face each other along the arrangement direction D11. The pair of anchor portions 430 are also provided at both ends of the main plate portion 410 in the arrangement direction D11 and are located rearward of the pair of outer side walls 420. For example, the pair of anchor portions 430 are bent downward with respect to the main plate portion 410 at both ends of the main plate portion 410 and face each other along the arrangement direction D11. When viewed from the front, the multiple shells 300 are positioned between the pair of outer side wall portions 420 and also between the pair of anchor portions 430 .

[0068] The pair of anchor portions 430 are held by the insulating housing 100. For example, the insulating housing 100 further has a pair of outer retaining holes 121 that respectively correspond to the pair of anchor portions 430. Each of the pair of outer retaining holes 121 passes through the insulating housing 100 from above. The pair of anchor portions 430 are inserted into the pair of outer retaining holes 121 from above.

[0069] The pair of outer side walls 420 may protrude forward beyond the front surface of the insulating housing 100. This allows the connector 3 to be smoothly guided along the mating direction D12.

[0070] A pair of protruding portions 412 that protrude forward beyond the front surface of the insulating housing 100 are formed on both ends of the main plate portion 410, and a pair of locking openings 411 are formed in each of the pair of protruding portions 412. When viewed from below, each of the pair of locking openings 411 is located between the multiple shells 300 and the pair of outer side walls 420. A pair of locking claws 814 of the connector 3, which will be described later, engage with the pair of locking openings 411, respectively.

[0071] The outer shell 400 may further include a pair of outer connection portions 421. The pair of outer connection portions 421 are formed on the pair of outer side wall portions 420, respectively, so as to be electrically connected to the circuit board 10 with the opposing surfaces 101 facing the circuit board 10. For example, each of the pair of outer connection portions 421 is formed on the lower edge of the corresponding outer side wall portion 420, and is connected to a ground terminal formed on the circuit board 10 by soldering or the like.

[0072] [Second connector] As described above, the connector 3 is connected to a plurality of cables 20. As shown in FIG. 11 in particular, each of the plurality of cables 20 has at least one signal conductor 24. One cable 20 transmits one type of signal. For example, the cable 20 transmits one type of differential signal. For example, one cable 20 has a pair of electric wires 21, an outer conductor 22, and an insulating outer sheath 23. Each of the pair of electric wires 21 has one signal conductor 24 and an insulating inner sheath 25 that covers the signal conductor 24. Hereinafter, the signal conductors 24 of the pair of electric wires 21 will be referred to as the pair of signal conductors 24. The above-mentioned differential signal is transmitted by the pair of signal conductors 24. The outer conductor 22 surrounds the pair of electric wires 21, and the outer sheath 23 covers the outer conductor 22.

[0073] Fig. 10 is an exploded perspective view of the connector 3, and Fig. 11 is a partially enlarged view of Fig. 10. As shown in Fig. 10, the connector 3 has a base unit 500 and a plurality of shells 600. As shown in Fig. 11, the base unit 500 has a connector base 510, a plurality of insulating housings 520, and a plurality of conductive contacts 530.

[0074] The connector base 510 has an opposing surface 511. The opposing surface 511 faces the outer peripheries of the ends of the multiple cables 20 arranged along the arrangement direction D21. The multiple insulating housings 520 correspond to the multiple cables 20, respectively. The multiple insulating housings 520 are lined up along the arrangement direction D21 and each protrudes away from the end of the corresponding cable 20 along a mating direction D22 that is parallel to the opposing surface 511 and perpendicular to the arrangement direction D21. The multiple insulating housings 520 are mated with the insulating housing 100 along the arrangement direction D11 and the mating direction D22, with the mating direction D12 and the mating direction D22 coinciding. For example, the multiple insulating housings 520 are respectively fitted into the spaces between the multiple protrusions 110 and the receding surface 102.

[0075] Hereinafter, for convenience of explanation, the direction in which the opposing surface 511 faces will be referred to as "upward," and the opposite direction will be referred to as "downward." Furthermore, the direction in which the multiple insulating housings 520 protrude from the connector base 510 will be referred to as "forward," and the opposite direction will be referred to as "rearward." According to this definition, the multiple cables 20 extend rearward from the connector base 510. When the connector 3 is mated with the connector 2, the up and down in the description of the connector 2 will coincide with the up and down in the description of the connector 3. Furthermore, the front in the description of the connector 3 corresponds to the rear in the description of the connector 2, and the rear in the description of the connector 3 corresponds to the front in the description of the connector 2.

[0076] The plurality of contacts 530 includes a plurality of pairs of contacts 530 respectively corresponding to the plurality of insulating housings 520. Each of the plurality of pairs of contacts 530 is held in the corresponding insulating housing 520, and comes into contact with each of the plurality of pairs of contacts 200 when the insulating housing 520 is fitted into the insulating housing 100. Each of the plurality of pairs of contacts 530 is connected to the pair of signal conductors 24 described above.

[0077] The multiple shells 600 correspond to the multiple insulating housings 520, respectively. Each of the multiple shells 600 is held by the insulating housing 520, and when the insulating housing 520 is mated with the insulating housing 100, the multiple shells 600 cooperate with the shell 300 to form an enclosure that surrounds the contacts 200 and 530 around an axis along the mating directions D12 and D22. The enclosure will be described in more detail below.

[0078] The connector 3 includes multiple sets of signal transmission parts TP2 corresponding to the multiple insulating housings 520, respectively. The multiple sets of signal transmission parts TP2 are arranged along the arrangement direction D21 and transmit the multiple types of signals described above, respectively. Below, the configuration of two sets of signal transmission parts TP2, the first and second from the right in the illustration (illustrated in FIGS. 10 and 11), will be illustrated in more detail as representative of the multiple sets of signal transmission parts TP2. The first signal transmission part TP2 from the right in the illustration corresponds to the first signal transmission part TP1 from the left in FIG. 7. The second signal transmission part TP2 from the right in the illustration corresponds to the second signal transmission part TP2 from the left in FIG. 7.

[0079] 11, the insulating housing 520, contacts 530, and shell 600 belonging to the first signal transmission portion TP2 from the right are referred to as a first insulating housing 520A, first contacts 530A, and first shell 600A, and the insulating housing 520, contacts 530, and shell 600 belonging to the second signal transmission portion TP2 from the right are referred to as a second insulating housing 520B, second contacts 530B, and second shell 600B. In addition, the cable 20 corresponding to the first signal transmission portion TP2 from the right is referred to as a first cable 20A, and the cable 20 belonging to the second signal transmission portion TP2 from the right is referred to as a second cable 20B.

[0080] The first insulating housing 520A and the second insulating housing 520B are aligned along the arrangement direction D21 and protrude forward from the connector base 510 along the fitting direction D22.

[0081] 11 , the first contact 530A and the second contact 530B are electrically connected to a pair of electric wires 21. For example, the first contact 530A is electrically connected to the signal conductor 24 of the electric wire 21 of the first cable 20A, and the second contact 530B is electrically connected to the signal conductor 24 of the electric wire 21 of the second cable 20B. The pair of first contacts 530A are held in the first insulating housing 520A, and are respectively connected to the signal conductors 24 of the pair of electric wires 21 of the first cable 20A. Each of the pair of first contacts 530A has a connecting portion 531 (first connecting portion) and a contact portion 532 (first contacting portion) that are aligned in order toward the front.

[0082] First insulating housing 520A holds a pair of first contacts 530A such that connecting portion 531 is exposed upward and contacting portion 532 is exposed downward (see FIG. 3). This allows signal conductor 24 to be connected to connecting portion 531 from above, and contacting portion 532 can come into contact with first contact 200A of a mating connector (connector 2) from above (see FIG. 4).

[0083] At the tip of the first cable 20A, in a portion corresponding to the connection portion 531, the outer sheath 23, the outer conductor 22, and the inner sheath 25 are removed, and a pair of exposed signal conductors 24 are connected to the connection portion 531, respectively.

[0084] The first contact 530A is formed by, for example, stamping and bending a thin metal plate material.

[0085] The pair of second contacts 530B are held in the second insulating housing 520B so as to be aligned with the pair of first contacts 530A along the arrangement direction D21, and are respectively connected to the signal conductors 24 of the pair of electric wires 21 of the second cable 20B. Each of the pair of second contacts 530B has a connecting portion 531 (second connecting portion) and a contact portion 532 (second contact portion), similar to the first insulating housing 520A.

[0086] The second insulating housing 520B holds a pair of second contacts 530B such that the connecting portions 531 are exposed upward and the contacting portions 532 are exposed downward (see FIG. 3). This allows the signal conductor 24 to be connected to the connecting portions 531 from above, and the contacting portions 532 can come into contact with the second contacts 200B of the mating connector (connector 2) from above (see FIG. 4).

[0087] At the tip of the second cable 20B, in a portion corresponding to the connection portion 531, the outer sheath 23, the outer conductor 22, and the inner sheath 25 are removed, and a pair of exposed signal conductors 24 are connected to the connection portion 531, respectively.

[0088] The first shell 600A is fixed to the connector base 510 so as to surround the first insulating housing 520A around an axis along the mating direction D22. For example, the first shell 600A has a cable holding portion 610 (first cable holding portion) and a mating portion 620 (first mating portion).

[0089] The cable holding portion 610 surrounds the first cable 20A and is fixed to the connector base 510. The outer sheath 23 is removed from the tip of the first cable 20A at a portion corresponding to the cable holding portion 610. The cable holding portion 610 surrounds the outer conductor 22 exposed by removing the outer sheath 23. The shape of the outer conductor 22 is not particularly limited. The cable holding portion 610 may surround the outer conductor 22 in a circular or polygonal shape. As an example, the cable holding portion 610 may surround the outer conductor 22 in a rectangular shape. For example, the cable holding portion 610 has a pair of side walls 611 (first base side walls) and a base 612 (first base). The pair of side walls 611 face each other along the arrangement direction D21. The outer conductor 22 of the first cable 20A is located between the pair of side walls 611 of the first shell 600A. The base portion 612 extends parallel to the opposing surface 511 and connects the pair of side wall portions 611 together.

[0090] The fitting portion 620 extends forward from the cable holding portion 610 along the fitting direction D22 to surround the first insulating housing 520A. There are no particular limitations on the shape surrounding the first insulating housing 520A. The fitting portion 620 may surround the first insulating housing 520A in a circular shape or in a polygonal shape. As an example, the fitting portion 620 may surround the first insulating housing 520A in a rectangular shape. For example, the fitting portion 620 has a pair of side walls 621 (first side walls) and a base portion 622 (first base portion). The pair of side walls 621 are continuous with the pair of side walls 611. The base portion 622 is continuous with the base portion 612 and connects the pair of side walls 621.

[0091] A gap 623 between the pair of base portions 622 is smaller than a gap 614 between the pair of side wall portions 611 (see FIG. 12 ). The outer conductor 22 of the first cable 20A is present inside the cable holding portion 610, whereas the outer conductor 22 of the first cable 20A is not present inside the fitting portion 620. By making the gap 623 at the position where the outer conductor 22 is not present smaller than the gap 614 at the position where the outer conductor 22 is present, it is possible to improve the uniformity of the positional relationship between the pair of signal conductors 24 and the metal body at ground potential that surrounds the pair of signal conductors 24, and further improve the signal transmission characteristics.

[0092] Returning to FIG. 11 , the fitting portion 620A fits into the upper portion of the first shell 300A. For example, the pair of side wall portions 621 overlap the inner surfaces of the pair of side wall portions 310 of the first shell 300A, respectively. When the fitting portion 620A fits into the first shell 300A in this manner, the first shell 300A complements the surrounding of the first insulating housing 520A by the fitting portion 620A. For example, the lower portion of the first insulating housing 520A that is not surrounded by the fitting portion 620A is surrounded by the first shell 300A.

[0093] Each of the pair of side wall portions 621 may have a resilient contact portion 624 (first resilient contact portion) (see FIGS. 12 and 13). The resilient contact portion 624 approaches the first insulating housing 520A when an external force is applied, and moves away from the first insulating housing 520A when the external force is removed. The resilient contact portions 624 of the pair of side wall portions 621 respectively contact the inner surfaces of the pair of side wall portions 310 of the first shell 300A. This allows the first shell 300A to further firmly complement the surrounding of the first insulating housing 520A by the fitting portion 620A.

[0094] The second shell 600B is fixed to the connector base 510 so as to surround the second insulating housing 520B around an axis along the mating direction D22. For example, the second shell 600B has a cable holding portion 610 (second Cable Retention and a fitting portion 620 (second end portion).

[0095] The cable holding portion 610 surrounds the second cable 20B and is fixed to the connector base 510. Similar to the cable holding portion 610 of the first shell 600A, the cable holding portion 610 of the second shell 600B includes a pair of side walls 611 (second base side walls) and a base portion 612 (second Nibe The outer sheath 23 is removed from a portion of the tip of the second cable 20B that corresponds to the cable holding portion 610. The cable holding portion 610 surrounds the outer conductor 22 that is exposed by removing the outer sheath 23.

[0096] The fitting portion 620 extends forward from the cable holding portion 610 along the fitting direction D22 and surrounds the second insulating housing 520B. Similar to the cable holding portion 610 of the first shell 600A, the fitting portion 620 of the second shell 600B has a pair of side walls 621 (second end side walls) and a base portion 622 (second end base).

[0097] The fitting portion 620B fits into an upper portion of the second shell 300B. For example, the pair of side wall portions 621 overlap the inner surfaces of the pair of side wall portions 310 of the second shell 300B, respectively. In this manner, when the fitting portion 620B fits into the second shell 300B, the surrounding of the second insulating housing 520B by the fitting portion 620B is complemented by the second shell 300B. For example, the lower portion of the second insulating housing 520B that is not surrounded by the fitting portion 620B is surrounded by the second shell 300B.

[0098] Like the pair of side walls 621 of the first shell 600A, each of the pair of side walls 621 of the second shell 600B may have a resilient contact portion 624 (second resilient contact portion).

[0099] The connector base 510 may have a conductive base plate 512 and an insulating base housing 513. The base plate 512 extends along the opposing surface and supports the multiple cables 20 from below. The base housing 513 holds the base plate 512, a first insulating housing 520A, and a second insulating housing 520B. The base unit 500 is formed by molding the base housing 513 and the multiple insulating housings 520 with a resin material by insert molding, with the base plate 512 and the multiple contacts 530 in place.

[0100] The cable holding portion 610 of the first shell 600A surrounds the outer conductor 22 of the first cable 20A with a pair of side walls 611, a base portion 612, and a base plate 512, and is fixed to the base plate 512. The cable holding portion 610 of the second shell 600B surrounds the outer conductor 22 of the second cable 20B with a pair of side walls 611, a base portion 612, and a base plate 512, and is fixed to the base plate 512. The base plate 512 electrically connects the cable holding portion 610 of the first shell 600A to the cable holding portion 610 of the second shell 600B.

[0101] In the cable holding portion 610 of the first shell 600A, the outer conductor 22 of the first cable 20A is electrically connected to the base plate 512. For example, the outer conductor 22 is fixed to the base plate 512 by soldering or the like. In the cable holding portion 610 of the second shell 600B, the outer conductor 22 of the second cable 20B is electrically connected to the base plate 512. For example, the outer conductor 22 is fixed to the base plate 512 by soldering or the like.

[0102] The base plate 512 may have a plurality of fixing holes 514 corresponding to the plurality of cables 20, respectively. The plurality of fixing holes 514 are aligned along the arrangement direction D11 and penetrate the base plate 512 in the up-down direction perpendicular to the facing surface 511. Each of the plurality of fixing holes 514 exposes the outer conductor 22 of the corresponding cable 20 downward.

[0103] The multiple fixing holes 514 include a first fixing hole 514A corresponding to the first cable 20A and a second fixing hole 514B corresponding to the second cable 20B. The first fixing hole 514A exposes the outer conductor 22 of the first cable 20A downward, and the second fixing hole 514B exposes the outer conductor 22 of the second cable 20B downward.

[0104] As described above for the first shell 600A and the second shell 600B, each of the multiple shells 600 has a pair of side wall portions 611, so the connector 3 has multiple pairs of side wall portions 611 aligned along the arrangement direction D21. In contrast, the base plate 512 may have multiple pairs of shell fixing holes 515 corresponding to the multiple pairs of side wall portions 611, respectively.

[0105] The multiple fixing holes 514 and the multiple pairs of shell fixing holes 515 are aligned in a row along the arrangement direction D21. In this arrangement, one fixing hole 514 is disposed between each of the multiple pairs of shell fixing holes 515. Each of the multiple pairs of shell fixing holes 515 penetrates the base plate 512 in the up-down direction, exposing a corresponding pair of side wall portions 611 downward. As a result, the multiple pairs of side wall portions 611 and the outer conductors 22 of the multiple cables 20 are exposed downward while aligned in a row. Therefore, the multiple pairs of side wall portions 611 and the outer conductors 22 of the multiple cables 20 can be fixed to the base plate 512 from below together by soldering or the like.

[0106] The multiple pairs of shell fixing holes 515 include a pair of first shell fixing holes 515A respectively corresponding to a pair of side wall portions 611 of the first shell 600A, and a pair of second shell fixing holes 515B respectively corresponding to a pair of side wall portions 611 of the second shell 600B. The first fixing hole 514A is located between the pair of first shell fixing holes 515A, and the second fixing hole 514B is located between the pair of second shell fixing holes 515B.

[0107] Each of the pairs of side wall portions 611 may have a fixing piece 613 inserted into the corresponding shell fixing hole 515. For example, each of the pair of side wall portions 611 of the first shell 600A may have a fixing piece 613 (first fixing piece) inserted into the corresponding first shell fixing hole 515A. Each of the pair of side wall portions 611 of the second shell 600B may have a fixing piece 613 (second fixing piece) inserted into the corresponding second shell fixing hole 515B. This allows the multiple shells 600 to be positioned and temporarily fixed to the base plate 512 before fixing by soldering or the like, thereby improving the workability when fixing the multiple pairs of side wall portions 611 and the outer conductors 22 of the multiple cables 20 to the base plate 512. The fixing piece 613 is fixed to the base plate 512 by soldering or the like while inserted into the corresponding shell fixing hole 515.

[0108] Returning to FIG. 10 , the connector 3 may further include an insulating outer housing 700. The outer housing 700 accommodates a connector base 510 to which multiple shells 600, including a first shell 600A and a second shell 600B, are fixed. The outer housing 700 may have a front wall 710 perpendicular to the mating direction D22. The front wall 710 may have multiple openings 711 corresponding to the multiple insulating housings 520, respectively. Each of the multiple insulating housings 520 protrudes forward from the outer housing 700 through the corresponding opening 711 while being surrounded by the shell 600.

[0109] The multiple openings 711 include a first opening 711A corresponding to the first insulating housing 520A and a second opening 711B corresponding to the second insulating housing 520B. The first insulating housing 520A is surrounded by the first shell 600A and protrudes forward from the outer housing 700 through the first opening 711A. The second insulating housing 520B is surrounded by the second shell 600B and protrudes forward from the outer housing 700 through the second opening 711B.

[0110] The connector 3 may further include an insulating separator 730 fixed to the outer housing 700 and regulating the spacing between the multiple cables 20, including the spacing between the first cable 20A and the second cable 20B. The separator 730 holds the multiple cables 20 from outside the outer sheath 23, behind the connector base 510. The connector base 510 is disposed between the front wall 710 and the separator 730. The separator 730 has multiple openings 731 corresponding to the multiple cables 20 (see FIGS. 2 and 3). The multiple openings 731 are aligned along the arrangement direction D21. Each of the multiple openings 731 penetrates the separator 730 along the mating direction D22. Each of the multiple cables 20 is held in its corresponding opening 731. The separator 730 maintains an appropriate distance between the cables 20, further improving signal transmission characteristics. The separator 730 also increases the strength with which the multiple cables 20 are fixed to the connector 3.

[0111] The separator 730 is formed by two-color resin molding with the base unit 500, the shells 600, and the outer housing 700 attached to the ends of the cables 20. The separator 730 may be formed by resin sealing using potting. The base unit 500, the shells 600, and the outer housing 700 may be attached to the ends of the cables 20 with a pre-molded separator 730 attached to the cables 20. In this case, the separator 730 may be molded into upper and lower members, each with the openings 731 at the center, and the upper and lower members may be combined to sandwich the cables 20. The separator 730 may be attached to the base unit 500 or may be molded integrally with the base unit 500. This further increases the fixing strength of the cables 20 to the connector 3.

[0112] The connector 3 may further include a locking member 800. The locking member 800 prevents the connector 3 from being disengaged from the connector 2. The locking member 800 has a pair of locking portions 810 and a locking knob 820. The pair of locking portions 810 are held by the outer housing 700 so as to correspond to the plurality of locking openings 411 (see FIG. 5 ) of the connector 2, respectively. The outer housing 700 further has, at both ends in the arrangement direction D11, a pair of lock accommodating portions 720 that open upward and backward, and a pair of hold bars 721 that correspond to the pair of lock accommodating portions 720, respectively. The pair of locking portions 810 are respectively accommodated in the pair of lock accommodating portions 720. Each of the pair of hold bars 721 is positioned above the rear end of the corresponding lock accommodating portion 720, and holds the locking portion 810 in the lock accommodating portion 720.

[0113] Each of the pair of locking sections 810 has a lock base 811, a lock plate 812, and an elastic connecting portion 813. The lock base 811 extends along the fitting direction D22 and contacts the bottom surface of the lock accommodating portion 720. The lock plate 812 extends along the fitting direction D22 at a position away from the bottom surface of the lock accommodating portion 720 and faces the lock base 811 in the up-down direction. A lock claw 814 that engages with the lock opening 411 of the connector 2 is formed on the upper surface of the lock plate 812. The elastic connecting portion 813 connects the front end of the lock base 811 to the front end of the lock plate 812 so as to enable elastic displacement of the lock claw 814 in the up-down direction.

[0114] The locking portion 810 can be switched between a locked state in which the locking claws 814 engage with the locking openings 411 and a released state in which the locking claws 814 do not engage with the locking openings 411. For example, when an external force is applied from above to the locking plate 812 to bring the locking plate 812 closer to the locking base 811, the locking claws 814 descend below the main plate portion 410, entering the released state. In this state, the connector 3 is mated with the connector 2, the locking claws 814 are positioned below the locking openings 411, the external force on the locking plate 812 is removed, and the locking plate 812 is elastically restored in a direction away from the locking base 811, whereby the locking claws 814 are positioned in the locking openings 411. As a result, the locking claws 814 engage with the inner periphery of the locking openings 411, and the released state is switched to the locked state. An external force is again applied from above to the lock plate 812, causing the lock plate 812 to approach the lock base 811 and lowering the lock claw 814, thereby switching the locked state back to the released state.

[0115] The lock knob 820 is an operating part for applying an external force to the lock plates 812 of the pair of locking parts 810 simultaneously to switch the locked state to the unlocked state. The lock knob 820 extends along the arrangement direction D21 to connect the lock plates 812 of the pair of locking parts 810, and protrudes rearward so as to hang over the multiple cables 20. By pressing the lock knob 820 down toward the multiple cables 20, an external force from above is applied to the lock plates 812 of the pair of locking parts 810 simultaneously, switching the locked state to the unlocked state. The locking member 800 is formed by stamping and bending a thin metal plate material, for example.

[0116] Since the pair of lock accommodating portions 720 are provided at both ends of the outer housing 700 in the arrangement direction D21, when viewed from the front, the multiple insulating housings 520 are disposed between the pair of locking portions 810. By arranging the pair of locking portions 810 in positions that do not overlap with the multiple insulating housings 520, it is possible to achieve both a reliable connection of the connector 3 to the connector 2 and a low profile of the connector system 1.

[0117] [Second connector assembly procedure] Next, as an example of a connector assembling method, an assembly procedure for the connector 3 will be illustrated. This procedure includes: orienting the outer periphery of the first cable 20A to face the facing surface 511 and connecting the signal conductor 24 of the first cable 20A to the first contact 530A; orienting the outer periphery of the second cable 20B to face the facing surface 511 and connecting the signal conductor 24 of the second cable 20B to the second contact 530B; arranging the first shell 600A to surround the first insulating housing 520A about an axis along the mating direction D22 with the signal conductor 24 of the first cable 20A connected to the first contact 530A; fixing the first shell 600A to the connector base 510; arranging the second shell 600B to surround the second insulating housing 520B about an axis along the mating direction D22 with the signal conductor 24 of the second cable 20B connected to the second contact 530B; and fixing the second shell 600B to the connector base 510.

[0118] The connection of the signal conductor 24 of the first cable 20A to the first contact 530A and the connection of the signal conductor 24 of the second cable 20B to the second contact 530B may be performed simultaneously. The fixing of the first shell 600A to the connector base 510 and the fixing of the second shell 600B to the connector base 510 may be performed simultaneously.

[0119] The assembly procedure for the connector 3 may further include housing the connector base 510, to which the first shell 600A and the second shell 600B are fixed, in an insulating outer housing 700.

[0120] Fixing the first shell 600A to the connector base 510 may include soldering the first shell 600A to the base plate 512 through the first shell fixing hole 515A and soldering the outer conductor 22 of the first cable 20A to the base plate 512 through the first fixing hole 514A, and fixing the second shell 600B to the connector base 510 may include soldering the second shell 600B to the base plate 512 through the second shell fixing hole 515B and soldering the outer conductor 22 of the second cable 20B to the base plate 512 through the second shell fixing hole 515B.

[0121] The soldering of the first shell 600A to the base plate 512, the soldering of the outer conductor 22 of the first cable 20A to the base plate 512, the soldering of the second shell 600B to the base plate 512, and the soldering of the outer conductor 22 of the second cable 20B to the base plate 512 may be performed simultaneously.

[0122] [Enclosure] 14 and 15, the shell 600 cooperates with the shell 300 to form an enclosure 900 that surrounds the contacts 200 and 530 about an axis Ax1 along the mating directions D12 and D22. For example, the first shell 600A cooperates with the first shell 300A to form a first enclosure 900A, and the second shell 600B cooperates with the second shell 300B to form a second enclosure 900B. The first enclosure 900A surrounds the first contacts 200A and 530A about a first axis Ax11 along the mating directions D12 and D22. The second enclosure 900B surrounds the second contacts 200B and 530B about a second axis Ax12 along the mating directions D12 and D22.

[0123] In the circumferential direction around the axis Ax1, the length of the portion where shell 300 forms the enclosure 900 without overlapping with shell 600 (hereinafter referred to as the "non-overlapping portion 912") and the portion where shell 600 forms the enclosure 900 without overlapping with shell 300 (hereinafter referred to as the "non-overlapping portion 913") are each longer than the total length of the portion where shell 300 and shell 600 overlap to form the enclosure 900 (hereinafter referred to as the "overlapping portion 911").

[0124] 15, the non-overlapping portion 912 includes the above-described base portion 320 and parts of the pair of side wall portions 310 (a pair of side portions 311). The pair of side portions 311 face each other in facing directions (e.g., arrangement directions D11 and D21) perpendicular to the fitting directions D12 and D22. The base portion 320 connects the pair of side portions 311. The non-overlapping portion 913 includes the above-described base portion 622. The base portion 622 faces the base portion 320.

[0125] In the overlapping portion 911, portions of the pair of side wall portions 310 (a pair of overlapping portions 312 respectively connected to the pair of side portions 311) and a pair of side wall portions 621 (a pair of mating overlapping portions) overlap at two positions aligned in the arrangement direction D11. For example, the pair of side wall portions 621 face each other in the facing direction, overlap the pair of overlapping portions 312 from the inside, and are maintained in contact with the shell 300. For example, the pair of side wall portions 621 are maintained in contact with the shell 300 by contacting the overlapping portions 312 with the elastic contact portions 624 elastically displaced inward. As a result, the shell 300 includes contact portions 313 (portions in contact with the elastic contact portions 624) that contact the shell 600 in the overlapping portion 911.

[0126] The enclosure 900 may surround the contacts 200 and 530 without any gaps, but gaps may be formed in the enclosure 900 in the circumferential direction.

[0127] At two locations aligned in the arrangement direction D11, the overlapping portions 911 have lengths L1 and L2 along the circumferential direction. The non-overlapping portions 912 have lengths L3 along the circumferential direction. The non-overlapping portions 913 have lengths L4 along the circumferential direction. The length L3 is longer than the sum of the lengths L1 and L2, and the length L4 is longer than the sum of the lengths L1 and L2. As shown in the figure, the lengths L3 and L4 each extend over the entire circumference of the enclosure 900. 1 of It may occupy more than 1 / 4.

[0128] In the above, a configuration has been exemplified in which the shell 300 overlaps with the shell 600 in the arrangement directions D11 and D21 that intersect (for example, are perpendicular to) the circumferential direction. As shown in Figures 16 and 17, the shell 300 may be configured to overlap with the shell 600 along the circumferential direction.

[0129] 16 and 17 has a wall portion 371 corresponding to one of the pair of side wall portions 310, and a wall portion 372 corresponding to the base portion 320, but does not have a wall portion opposite to the wall portion 371. A slit 373 is formed in the wall portion 371 along the arrangement direction D11. The slit 373 is open toward the shell 600.

[0130] Shell 600 has a wall portion 632 corresponding to base portion 622 and a wall portion 631 continuing to wall portion 632 along the circumferential direction. Wall portion 631 is perpendicular to wall portion 632. Wall portion 631 has a slit 633 formed along arrangement direction D21. Slit 633 is open toward shell 300.

[0131] Wall portion 632 faces wall portion 372 and is fitted into slit 373 of wall portion 371, thereby maintaining contact with shell 300 along the circumferential direction. Wall portion 372 is fitted into slit 633 of wall portion 631, thereby maintaining contact with shell 300 along the circumferential direction. Shell 300 overlaps with shell 600 along the circumferential direction at the portion where wall portion 632 is fitted into slit 373 and the portion where wall portion 372 is fitted into slit 633. The portion where shell 300 and shell 600 overlap in the circumferential direction constitutes part of enclosure 900, and therefore the portion where wall portion 632 is fitted into slit 373 and the portion where wall portion 372 is fitted into slit 633 both correspond to overlapping portion 911. The length of overlapping portion 911 in the circumferential direction is substantially zero.

[0132] 16, contact protrusions 374 that protrude inward and come into contact with wall portion 632 (for example, come into contact with the outer surface of wall portion 632) may be formed on the inner edge of slit 373. Similarly, contact protrusions 634 that protrude inward and come into contact with wall portion 372 (for example, come into contact with the outer surface of wall portion 372) may be formed on the inner edge of slit 633.

[0133] 〔summary〕 The above-described exemplary embodiment includes the following configurations. (1) A connector 2 includes an insulating housing 100, conductive contacts 200 held in the insulating housing 100, and a conductive shell 300 held in the insulating housing 100 so as to surround the contacts 200; a mating insulating housing 520 that mates with the insulating housing 100 along a mating direction D12; a conductive mating contact 530 that is held in the mating insulating housing 520 and comes into contact with the contacts 200 when the mating insulating housing 520 is mated with the insulating housing 100; and a mating insulating housing 530 that is held in the mating insulating housing 520 and comes into contact with the contacts 200 when the mating insulating housing 520 is mated with the insulating housing 100. and a mating connector (3) having a conductive mating shell (600) that, when mated to the connector (100), cooperates with the shell (300) to form an enclosure (900) that surrounds the contact (200) and the mating contact (530) around an axis along the mating direction (D12), wherein, in the circumferential direction around the axis, the length of each of the portion where the shell (300) does not overlap with the mating shell (600) to form the enclosure (900) and the portion where the mating shell (600) does not overlap with the shell (300) to form the enclosure (900) is longer than the total length of the portion where the shell (300) and the mating shell (600) overlap to form the enclosure (900). It is possible to form an enclosure 900 that surrounds the contact 200 and the mating contact 530 while reducing the overlapping portion between the shell 300 and the mating shell 600. This is therefore effective in achieving both reliable signal transmission and miniaturization.

The mating connector 3 includes conductive mating second contacts 530B held in the mating insulating housing 520 so as to be aligned with the mating contacts 530 along the arrangement direction D11, and which come into contact with the second contacts 200B when the mating insulating housing 520 is mated with the insulating housing 100, and a conductive mating second shell 300B held in the mating insulating housing 520 and which, when the mating insulating housing 520 is mated with the insulating housing 100, constitutes a second enclosure 900B that cooperates with the second shell 300B to surround the second contacts 200B and the mating second contacts 530B around an axis along the mating direction D12. 600 B, and in the circumferential direction around the axis, 600 B, and the portion where the second shell 300B forms the second enclosure 900B ... 600 The length of each of the portions of the second shell 300B and the portion of the second surrounding body 900B is 600 The connector system 1 according to (1) is longer than the overall length of the portion that overlaps with B to form the second enclosure 900B. The second surrounding body 900B can be configured while reducing the overlapping portion between the second shell 300B and the mating second shell 300B for the second contact 200B and the mating second contact 530B, which is further effective in achieving both reliable signal transmission and compactness.

[0135] (3) A connector system 1 as described in (2), wherein the contact 200 and the second contact 200B are electrically connected to a first signal line and a second signal line on a circuit board, and the mating contact 530 and the mating second contact 530B are electrically connected to a first signal conductor and a second signal conductor of one or more cables.

[0139] (7) A connector system 1 described in any one of (1) to (6), wherein the length of the portion of the shell 300 that does not overlap with the mating shell 600 and forms the surrounding body 900, and the length of the portion of the shell 600 that does not overlap with the shell 300 and forms the surrounding body 900, each account for more than 1 / 4 of the entire circumference of the surrounding body 900. This is even more effective in reducing size.

[0140] (8) The portion of the shell 300 that does not overlap with the mating shell 600 and forms the enclosure 900 is a pair of side portions 311 that face each other in the facing direction perpendicular to the fitting direction D12, and a base portion that connects the pair of side portions 311. 320 The portion of the mating shell 600 that does not overlap with the shell 300 and forms the enclosure 900 is the base portion. 320 and the opposing base part 622 The connector system 1 according to (7) includes: This is even more effective in reducing size.

[0141] (9) A connector system 1 described in (8), in which the shell 300 has a pair of overlapping portions 312 respectively connected to a pair of side portions 311, and the mating shell 600 has a pair of mating overlapping portions 621 which face each other in the opposing direction, overlap the pair of overlapping portions 312 from the inside, and are maintained in contact with the shell 300.

[0144] (12) The mating shell 600 has a mating wall portion 632 Counterpart crossing wall 631 Further, the mating cross wall portion 631 The mating slit 633 is formed in the shell 300 along the mating direction D12, and the mating cross wall portion 631 The connector system (1) according to (11) has a cross wall portion (372) that is kept in contact with the mating shell (600) along the circumferential direction by crossing the mating shell (600) and fitting into a mating slit (633).
