DETAILED DESCRIPTION OF THE INVENTION

[0010] 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.

[0011] [Connector System] The connector system 1 shown in FIG. 1 is a system that electrically connects a pair of connection objects to each other. The pair of connection objects may be a cable and a circuit board, two circuit boards, or two cables. The connector system 1 includes a plug connector 100 and a receptacle connector 200 that mate with each other along a mating direction D1. The receptacle connector 200 is a "mating connector" for the plug connector 100, and the plug connector 100 is a "mating connector" for the receptacle connector 200. As an example, the receptacle connector 200 is connected to a circuit board, and the plug connector 100 is connected to multiple cables. When the plug connector 100 is connected to the receptacle connector 200, the multiple cables are electrically connected to the circuit board. The mating direction D1 is parallel to the circuit board.

[0012] The plug connector 100 has a plurality of contacts 110 and a housing 140. The plurality of contacts 110 are arranged in an arrangement direction D2 perpendicular to the mating direction D1. Each of the plurality of contacts 110 is conductive and extends along the mating direction D1. In the illustration, the plug connector 100 has six contacts 110, but the number of contacts 110 can be changed. The plurality of contacts 110 are connected to the center conductors 11 of the plurality of cables 10 arranged along the mating direction D1, respectively. The housing 140 has insulating properties and holds the plurality of contacts 110 in a state in which they are insulated from one another.

[0013] The multiple contacts 110 include a pair of contacts 110A, 110B located at both ends in the arrangement direction D2 (both ends of the arrangement of the multiple contacts 110). The pair of contacts 110A, 110B each have a pair of guide surfaces GS1, GS2 exposed in opposite directions from the housing 140 in the arrangement direction D2. For example, the guide surface GS1 of the contact 110A is exposed from the housing 140 in a direction away from the contact 110B, and the guide surface GS2 of the contact 110B is exposed from the housing 140 in a direction away from the contact 110A.

[0014] The receptacle connector 200 has a plurality of contacts 240, 250 and a pair of guide surfaces GS11, GS12. The plurality of contacts 240, 250 are conductive and come into contact with the plurality of contacts 110, respectively. The pair of guide surfaces GS11, GS12 come into contact with a pair of guide surfaces GS1, GS2 of the plug connector 100, respectively, to restrict displacement of the plug connector 100 in the arrangement direction D2.

[0015] 2 is a cross-sectional view of the plug connector 100 and the receptacle connector 200 during the mating process along the mating direction D1. As shown in FIG. 2, guide surface GS11 faces guide surface GS1, and guide surface GS12 faces guide surface GS2. When guide surface GS1 contacts guide surface GS11, displacement of the plug connector 100 in one direction in the arrangement direction D2 is restricted. Similarly, when guide surface GS2 contacts guide surface GS12, displacement of the plug connector 100 in the other direction in the arrangement direction D2 is restricted.

[0016] In this way, by providing a pair of guide surfaces GS1, GS2 on the pair of contacts 110A, 110B, respectively, and providing a pair of guide surfaces GS11, GS12 that contact the pair of guide surfaces GS1, GS2, respectively, on the receptacle connector 200, the pair of contacts 110A, 110B can be used both for electrical connection and as a guide for mating. Therefore, the connector system 1 is effective in achieving both ease of mating and miniaturization.

[0017] The housing 140 may have a pair of side walls 147A, 147B. The pair of side walls 147A, 147B sandwich the plurality of contacts 110 in the arrangement direction D2. The pair of contacts 110A, 110B may have a pair of protrusions 117A, 117B. The pair of contacts 110A, 110B protrude to the outer surfaces of the pair of side walls 147A, 147B along the arrangement direction D2. For example, the contact 110A protrudes to the outer surface of the side wall 147A (the surface facing away from the side wall 147B). The contact 110B protrudes to the outer surface of the side wall 147B (the surface facing away from the side wall 147A). Protruding to the outer surface includes protruding further from the outer surface. For example, the end face of contact 110A may be flush with the outer surface of side wall 147A or may protrude beyond the outer surface of side wall 147A. Similarly, the end face of contact 110B may be flush with the outer surface of side wall 147B or may protrude beyond the outer surface of side wall 147B.

[0018] The pair of guide surfaces GS1, GS2 may be formed on the pair of protrusions 117A, 117B, respectively. For example, the end face of protrusion 117A is guide surface GS1, and the end face of protrusion 117B is guide surface GS2. Due to the complementary relationship in which the pair of side walls 147A, 147B reinforce the pair of contacts 110A, 110B, while the pair of protrusions 117A, 117B protect the pair of side walls 147A, 147B, respectively, it is possible to achieve both strength and miniaturization of plug connector 100.

[0019] Each of the multiple contacts 110 has a leading end FE1 extending toward the receptacle connector 200 along the mating direction D1. The pair of contacts 110A, 110B each has a pair of leading ends FE11, FE12 extending toward the receptacle connector 200 along the mating direction D1. In the mating direction D1, the pair of protrusions 117A, 117B may be located between the pair of sidewalls 147A, 147B and the pair of leading ends FE11, FE12. Peeling of the pair of sidewalls 147A, 147B due to contact with the receptacle connector 200, for example, can be prevented by the pair of protrusions 117A, 117B. In the mating direction D1, the pair of sidewalls 147A, 147B may be longer than the distance from the pair of protrusions 117A, 117B to the pair of leading ends FE11, FE12.

[0020] The receptacle connector 200 may further include an insulating housing 210 that holds a plurality of contacts 240, 250. The housing 210 may have a pair of guide surfaces GS11, GS12. Electrical contact with the pair of guide surfaces GS1, GS2 can be easily prevented.

[0021] For example, the housing 210 has a recess 214 that receives the housing 140 along the fitting direction D1. The pair of guide surfaces GS11, GS12 are formed on an inner surface 221 of the recess 214. With a simple configuration in which the recess 214 is formed in the housing 210, the pair of guide surfaces GS11, GS12 can be formed.

[0022] The configurations of the plug connector 100 and the receptacle connector 200 will be described in more detail below.

[0023] [Plug connector] As described above, the plug connector 100 is connected to a plurality of cables 10. As shown in Fig. 3, each of the plurality of cables 10 has a center conductor 11 and an insulating sheath 14. The center conductor 11 may be a solid wire made of metal such as copper, or may be a stranded wire. The center conductors 11 of the plurality of cables 10 are connected to the plurality of contacts 110, respectively, along the mating direction D1.

[0024] The multiple cables 10 are arranged in the arrangement direction D2 and include a pair of cables 10A, 10B located at both ends of the arrangement direction D2. The pair of cables 10A, 10B are coaxial cables and further include a dielectric layer 12 and an outer conductor 13. The dielectric layer 12 covers the central conductor 11. The outer conductor 13 covers the dielectric layer 12. The outer conductor 13 may be a braided wire of a metal such as copper, or may be a metal foil. A sheath 14 covers the outer conductor 13.

[0025] 4 is a perspective view illustrating the contacts 110 other than the pair of contacts 110A, 110B among the plurality of contacts 110. As shown in FIG. 4, each of the plurality of contacts 110 (hereinafter simply referred to as "contact 110") has a contact portion 111 and a connecting portion 112. The connecting portion 112 is connected to the center conductor 11 of a corresponding cable 10 among the plurality of cables 10. The contact portion 111 comes into contact with the contact 240 or the contact 250 when the plug connector 100 is mated with the receptacle connector 200.

[0026] The contacts 110 extend along the mating direction D1 and have a leading end FE1 and a base end BE1. The leading end FE1 is the end that faces the receptacle connector 200 along the mating direction D1, and the base end BE1 is the end opposite the leading end FE1. For example, the contacts 110 are formed from a plate material P1 that extends along the arrangement direction D2 and the mating direction D1. For example, the plate material P1 is a thin plate material made of metal such as copper.

[0027] The connection portion 112 is formed at the base end of the contact 110 (base end BE1 and its vicinity), and the contact portion 111 is formed at the tip end of the contact 110 (tip FE1 and its vicinity). The connection portion 112 has a connection surface 116 exposed from the housing 140. The contact portion 111 is connected to the connection surface 116 by soldering, solid-state welding, or the like. Hereinafter, for convenience, the side facing the connection surface 116 will be referred to as "upper," but this does not mean that the connection surface 116 faces upward in actual use.

[0028] The contact portion 111 has a first contact surface 113 and a second contact surface 114 exposed from the housing 140 in opposite directions in an orthogonal direction D3 perpendicular to the mating direction D1 and the arrangement direction D2. Both the first contact surface 113 and the second contact surface 114 contact the contact 240 or the contact 250. The first contact surface 113 faces upward, and the second contact surface 114 faces downward. The contact 110 may have a second protrusion 115 protruding downward along the orthogonal direction D3, and the second contact surface 114 may be formed on the second protrusion 115. For example, the lower end surface of the second protrusion 115 is the second contact surface 114.

[0029] The second protrusion 115 may be formed by folding back the plate material P1 and partially overlapping it. This makes it easy to form the second protrusion 115. For example, the second protrusion 115 may be formed by folding back the plate material P1 at the tip FE1 around the arrangement direction D2. By folding back the plate material P1 around the arrangement direction D2, a curved surface CS1 that is curved around the arrangement direction D2 is formed at the tip FE1. In this way, by providing the tip FE1 with a rounded shape due to bending, it is possible to further improve the ease of fitting.

[0030] FIG. 5 is a perspective view illustrating a pair of contacts 110A, 110B among the multiple contacts 110. Like the other contacts 110, each of the pair of contacts 110A, 110B has a contact portion 111 and a connecting portion 112. The connecting portion 112 has a connecting surface 116 facing upward. The connecting surfaces 116 of the pair of contacts 110A, 110B are connected to the center conductors 11 of the pair of cables 10A, 10B, respectively. The contact portion 111 has a first contact surface 113 facing upward and a second contact surface 114 facing downward. Each of the pair of contacts 110A, 110B may have a second protrusion 115 protruding downward, and the second contact surface 114 may be formed on the second protrusion 115.

[0031] Each of the pair of contacts 110A, 110B may be formed from a plate material P1, similar to the other contacts 110. The second convex portion 115 may be formed by folding back the plate material P1 and partially overlapping it. For example, the second convex portion 115 may be formed by folding back the plate material P1 at the tip FE1 around the arrangement direction D2.

[0032] As described above, the pair of contacts 110A, 110B each have a pair of guide surfaces GS1, GS2. For example, the pair of contacts 110A, 110B each have a pair of protrusions 117A, 117B that protrude in opposite directions along the arrangement direction D2, and the pair of guide surfaces GS1, GS2 are respectively formed by the end surfaces of the pair of protrusions 117A, 117B. The protrusion 117A protrudes from the outer surface of the contact portion 111 (the surface facing away from the contact 110B). The width of the protrusion 117A in the mating direction D1 may gradually decrease as it protrudes. Similarly, the protrusion 117B protrudes from the outer surface of the contact portion 111 (the surface facing away from the contact 110A). The width of the protrusion 117B in the mating direction D1 may gradually decrease as it protrudes.

[0033] The protrusion 117A may be formed on each of the overlapping plate materials P1 to form the second protrusion 115 (forming the first contact surface 113 and the second contact surface 114). Similarly, the protrusion 117B may be formed on each of the overlapping plate materials P1 to form the second protrusion 115 (forming the first contact surface 113 and the second contact surface 114). This can improve the strength of the pair of protrusions 117A, 117B. The thickness t2 of the plate material P1 forming the pair of contacts 110A, 110B may be thicker than the thickness t1 (see FIG. 4) of the plate material P1 forming the other contact 110. This can further improve the strength of the pair of protrusions 117A, 117B.

[0034] 6 is a perspective view illustrating the shell 130. The shell 130 is conductive and at least partially covers the housing 140 around the mating direction D1. The shell 130 may at least partially surround the contacts 110 around the mating direction D1 (see FIG. 7). For example, the shell 130 is formed from a plate material P2 that is aligned along the arrangement direction D2 and the mating direction D1. For example, the plate material P2 is a thin plate material made of metal such as copper.

[0035] The shell 130 has a base plate 131 and a pair of side plates 132A, 132B. The base plate 131 extends along the arrangement direction D2 and the mating direction D1 and faces the plurality of contacts 110 from below in the orthogonal direction D3 (see FIG. 7). The base plate 131 has a tip end FE2 and a base end BE2. The tip end FE2 is the end facing the receptacle connector 200 along the mating direction D1, and the base end BE2 is the end opposite the tip end FE2. The pair of side plates 132A, 132B are provided at the tip portion of the base plate 131 (the tip end FE2 and its vicinity). The pair of side plates 132A, 132B protrude upward from both ends of the base plate 131 in the arrangement direction D2. For example, each of the pair of side plates 132A, 132B is bent relative to the base plate 131 around the mating direction D1 and protrudes upward.

[0036] The side plate 132A extends along the orthogonal direction D3 and the mating direction D1 and faces the contact 110A from the outside in the arrangement direction D2. For example, the side plate 132A faces the portion of the contact 110A between the contact portion 111 and the connecting portion 112 (see FIG. 7). Similarly, the side plate 132B extends along the orthogonal direction D3 and the mating direction D1 and faces the contact 110B from the outside in the arrangement direction D2. For example, the side plate 132B faces the portion of the contact 110B between the contact portion 111 and the connecting portion 112 (see FIG. 7).

[0037] The base plate 131 extends further rearward (away from the receptacle connector 200) than the base ends BE1 of the contacts 110 to form a shell connecting portion 134. The shell connecting portion 134 has a connecting surface 135 exposed upward. As will be described later, the outer conductors 13 of the pair of cables 10A, 10B are connected to the connecting surface 135.

[0038] A protruding portion 133 protruding downward along the orthogonal direction D3 is formed at the base end (at the base end BE2 and its vicinity) of the base plate 131, including the shell connecting portion 134. The protruding portion 133 may be formed by folding back and partially overlapping the plate material P2. For example, the protruding portion 133 may be formed by folding back the plate material P2 at the base end BE1 around the arrangement direction D2. The shell 130 may be divided into a first shell 130A and a second shell 130B aligned along the arrangement direction D2. For example, the shell 130 may be divided into a first shell 130A having a side plate 132A and a second shell 130B having a side plate 132B by a slit that divides the base plate 131 and the protruding portion 133 from the tip end FE2 to the base end BE2.

[0039] 8 and 9, the housing 140 is formed to hold the plurality of contacts 110 and the shell 130. The housing 140 is formed of an insulating material (e.g., a resin material). For example, the housing 140 is formed by insert molding of a resin material in a state in which the plurality of contacts 110 are arranged in the arrangement direction D2 and the shell 130 is arranged to partially surround the plurality of contacts 110 around the mating direction D1 (see FIG. 7).

[0040] For example, the housing 140 has a contact support portion 141, a shell support portion 142, and a separator portion 144. The contact support portion 141 supports the plurality of contacts 110 from one side in the orthogonal direction D3. For example, the contact support portion 141 extends below the plurality of contacts 110 along the arrangement direction D2 and the mating direction D1 to support the plurality of contacts 110. A portion of the contact support portion 141 also extends between the plurality of contacts 110 and the base plate 131, keeping the plurality of contacts 110 insulated from the shell 130.

[0041] The shell support portion 142 extends below the base plate 131 along the arrangement direction D2 and the fitting direction D1, and supports the shell 130. The base plate 131 is sandwiched between the contact support portion 141 and the shell support portion 142 from above and below.

[0042] The separator 144 fills the gap between the side plates 132A and 132B above the multiple contacts 110. The multiple contacts 110 are sandwiched from above and below by the separator 144 and the contact support 141. The separator 144 separates the first contact surface 113 of the contact portion 111 from the connection surface 116 of the connection portion 112. The portion of the contact support 141 that protrudes from the separator 144 toward the tip FE1 of the multiple contacts 110 includes the pair of side wall portions 147A, 147B described above. The pair of side wall portions 147A, 147B each protrude from the separator 144 toward the tip FE1 so as to sandwich the multiple contacts 110 in the arrangement direction D2.

[0043] The pair of protrusions 117A, 117B of the pair of contacts 110A, 110B protrude to the outer surfaces of the pair of side wall portions 147A, 147B, respectively. The end faces of the pair of protrusions 117A, 117B are exposed outward from the pair of side wall portions 147A, 147B to form the pair of guide surfaces GS1, GS2, respectively. The length by which the pair of side wall portions 147A, 147B protrude from the separator portion 144 is longer than the length from the pair of protrusions 117A, 117B to the tips FE11, FE12.

[0044] As shown in FIG. 9, the second protrusion 115 of the contact 110 protrudes to the outer surface (lower surface) of the contact support portion 141, and the second contact surface 114 is exposed downward from the contact support portion 141. The protrusion 133 of the shell 130 protrudes to the outer surface (lower surface) of the shell support portion 142. As shown in FIG. 10, a plurality of cables 10 are connected to the plug connector 100. For example, the ends of the plurality of cables 10 arranged in the arrangement direction D2 have portions where the center conductors 11 are exposed. Furthermore, the pair of cables 10A and 10B have portions where the outer conductors 13 are exposed. The center conductors 11 of the plurality of cables 10 are connected to the connection surfaces 116 of the plurality of contacts 110, respectively. The outer conductors 13 of the pair of cables 10A and 10B are connected to the connection surface 135 of the shell 130 via the ground bar 150.

[0045] When the shell 130 is divided into a first shell 130A and a second shell 130B, the outer conductors 13 of the pair of cables 10A, 10B are connected to the connection surfaces 135 of the first shell 130A and the second shell 130B while being insulated from each other. For example, as shown in Fig. 11, the outer conductors 13 of the pair of cables 10A, 10B are connected to the connection surfaces 135 of the first shell 130A and the second shell 130B via a first ground bar 150A and a second ground bar 150B that are spaced apart from each other in the arrangement direction D2. For example, the outer conductor 13 of the cable 10A is connected to the first ground bar 150A from above by soldering or the like, and the first ground bar 150A is connected to the connection surface 135 of the first shell 130A by soldering or the like. Similarly, the outer conductor 13 of the cable 10B is connected from above by soldering or the like to the second ground bar 150B, and the second ground bar 150B is connected to the connection surface 135 of the second shell 130B by soldering or the like.

[0046] [Receptacle connector] As shown in FIG. 12, the receptacle connector 200 includes a housing 210, a plurality of contacts 240, 250, and a shell 260. The housing 210 is formed by injection molding or the like using a resin material and has insulating properties. As shown in FIGS. 13 and 14, the housing 210 includes a main body 211 and a recess 212. The main body 211 extends along the arrangement direction D2 and the mating direction D1. The main body 211 has a rectangular parallelepiped shape. For example, the main body 211 has a pair of end faces 216A, 216B facing opposite each other in the mating direction D1, a pair of side faces 217A, 217B facing opposite each other in the arrangement direction D2, and a pair of flat faces 215A, 215B facing opposite each other in the orthogonal direction D3.

[0067] FIG. 17 is a perspective view illustrating the shell 260. The shell 260 is formed of a thin metal plate, such as copper, and is conductive. The shell 260 at least partially covers the housing 210 in the mating direction D1. The shell 260 may at least partially surround the contacts 240, 250 in the mating direction D1. As shown in FIG. 17, the shell 260 includes a cover plate 261, side plates 262A, 262B, a pair of front plates 263A, 263B, a pair of contact pieces 264A, 264B, a pair of back plates 265A, 265B, and a pair of insert pieces 266A, 266B. The cover plate 261 extends along the arrangement direction D2 and the mating direction D1 and at least partially covers the housing 210 from above. The cover plate 261 is rectangular and has a pair of opposite edges 261A and 261B in the fitting direction D1 and a pair of opposite side edges 261C and 261D in the arrangement direction D2. The edge 261A faces forward, and the edge 261B faces rearward.

[0068] The pair of side plates 262A, 262B protrude downward from the pair of side edges 261C, 261D, respectively, and cover the pair of side surfaces 217A, 217B of the housing 210. For example, the side plate 262A is bent downward around the fitting direction D1 with respect to the housing 210, and expands along the orthogonal direction D3 and the fitting direction D1. Similarly, the side plate 262B is bent downward around the fitting direction D1 with respect to the housing 210, and expands along the orthogonal direction D3 and the fitting direction D1.

[0069] Each of the pair of side plates 262A, 262B has a connecting portion 271 at an end. The connecting portion 271 is connected to a ground pattern of the circuit board by soldering or the like. The connecting portion 271 is bent outward (away from the side plate 262B) around the mating direction D1 relative to the side plate 262A. Similarly, the connecting portion 271 is bent outward (away from the side plate 262A) around the mating direction D1 relative to the side plate 262B.

[0070] The pair of front plates 263A, 263B are aligned in the arrangement direction D2 and each protrude downward from the edge 261A. The pair of front plates 263A, 263B respectively cover the pair of blocks 220A, 220B of the housing 210 from the front. Each of the pair of front plates 263A, 263B is bent downward around the arrangement direction D2 with respect to the housing 210 and expands along the orthogonal direction D3 and the arrangement direction D2.

[0071] Each of the pair of front plates 263A, 263B has a connecting portion 272 at an end thereof. The connecting portion 272 is connected to a ground pattern of the circuit board by soldering or the like. The connecting portion 272 is bent forward around the arrangement direction D2 relative to each of the pair of front plates 263A, 263B.

[0072] The pair of contact pieces 264A, 264B are connected to the pair of front plates 263A, 263B, respectively, and come into contact with the pair of side plates 132A, 132B of the plug connector 100. For example, the pair of contact pieces 264A, 264B are connected to the inner edges of the pair of front plates 263A, 263B, respectively. The inner edge of the front plate 263A represents the edge facing the front plate 263B, and the inner edge of the front plate 263B represents the edge facing the front plate 263A.

[0073] For example, the contact piece 264A is bent inward (toward the inside of the second contact surface 114) around the orthogonal direction D3 relative to the front plate 263A. Similarly, the contact piece 264B is bent inward around the orthogonal direction D3 relative to the front plate 263B. The distance between the pair of contact pieces 264A, 264B in the arrangement direction D2 gradually decreases as the distance increases from the pair of front plates 263A, 263B. Each of the pair of contact pieces 264A, 264B has a contact portion 273 at its end. The contact portion 273 of the contact piece 264A contacts the side plate 132A, and the contact portion 273 of the contact piece 264B contacts the side plate 132B. The shell 130 may be configured so that the pair of side plates 132A, 132B come into contact with the contact portions 273 of the pair of contact pieces 264A, 264B, respectively, after the pair of guide surfaces GS1, GS2 enter between the pair of guide surfaces GS11, GS12. For example, the shell 130 is configured so that the contact portions 273 of the pair of contact pieces 264A, 264B do not come into contact with the pair of side plates 132A, 132B until the plug connector 100 is further pushed into the receptacle connector 200 after the pair of guide surfaces GS1, GS2 enter between the pair of guide surfaces GS11, GS12.

[0074] The pair of back plates 265A, 265B are aligned in the arrangement direction D2 and each protrude downward from the edge 261B. The pair of back plates 265A, 265B cover the main body 211 of the housing 210 from the rear. Each of the pair of back plates 265A, 265B is bent downward around the arrangement direction D2 with respect to the housing 210 and expands along the orthogonal direction D3 and the arrangement direction D2.

[0075] Each of the pair of back plates 265A, 265B has a connecting portion 274 at an end thereof. The connecting portion 274 is connected to a ground pattern of the circuit board by soldering or the like. The connecting portion 274 is bent backward around the arrangement direction D2 relative to each of the pair of back plates 265A, 265B.

[0076] The pair of insert pieces 266A, 266B are aligned between the pair of side plates 262A, 262B in the arrangement direction D2 and each protrudes downward. The side plate 262A protrudes away from the side plate 262A within an opening formed in the cover plate 261 at a position closer to the side plate 262A and is bent downward relative to the cover plate 261 around the fitting direction D1. Similarly, the side plate 262B protrudes away from the side plate 262B within an opening formed in the cover plate 261 at a position closer to the side plate 262B and is bent downward relative to the cover plate 261 around the fitting direction D1. The pair of insert pieces 266A, 266B are press-fitted into the housing 210 from above. The shell 260 is held in the housing 210 by the press-fitting of the pair of insert pieces 266A, 266B.

[0077] When the shell 130 is divided into a first shell 130A and a second shell 130B, the shell 260 may be divided into a first shell 260A and a second shell 260B corresponding to the first shell 130A and the second shell 130B, respectively. The shell 260 may be divided into the first shell 260A and the second shell 260B by a slit dividing the cover plate 261 from the edge 261A to the edge 261B. The first shell 260A has a side plate 262A, a front plate 263A, a contact piece 264A, a back plate 265A, and an insert piece 266A. The second shell 260B has a side plate 262B, a front plate 263B, a contact piece 264B, a back plate 265B, and an insert piece 266B. When shell 260 is divided into first shell 260A and second shell 260B, the ground pattern of the circuit board may also be divided into a portion corresponding to first shell 260A and a portion corresponding to second shell 260B. When shell 130 is divided into first shell 130A and second shell 130B, and shell 260 is divided into first shell 260A and second shell 260B, and the ground pattern of the circuit board is divided into the above two portions, outer conductors 13 of a pair of cables 10A and 10B are individually connected to the ground pattern of the circuit board.

By providing a pair of guide surfaces GS1 and GS2 on the pair of contacts 110A and 110B, respectively, and providing a pair of mating guide surfaces GS11 and GS12 that contact the pair of guide surfaces GS1 and GS2, respectively, on the mating connector 200, the pair of contacts 110A and 110B can be used both for electrical connection and as a guide for mating. Therefore, this connector system 1 is effective in achieving both ease of mating and miniaturization.

[0079] (2) The housing 140 has a pair of side wall portions 147A, 147B that sandwich the multiple contacts 110 in the arrangement direction D2, and the pair of contacts 110A, 110B have a pair of protrusions 117A, 117B that protrude along the arrangement direction D2 to the outer surfaces of the pair of side wall portions 147A, 147B, respectively, and the pair of guide surfaces GS1, GS2 are formed on the pair of protrusions 117A, 117B, respectively, in the connector system 1 described in (1). The pair of contacts 110A, 110B are reinforced by the pair of side wall portions 147A, 147B, while the pair of protrusions 117A, 117B protect the pair of side wall portions 147A, 147B, respectively, resulting in a complementary relationship that allows the connector 100 to be both strong and compact.

[0080] (3) A connector system 1 described in (2), in which the pair of contacts 110A, 110B have a pair of tips FE11, FE12 that extend toward the mating connector 200 along the mating direction D1, and in the mating direction D1, the pair of protrusions 117A, 117B are positioned between the pair of side wall portions 147A, 147B and the pair of tips FE11, FE12, respectively.

The ease of mating can be further improved by restricting the displacement of the connector 100 in the arrangement direction D2 with a pair of mating guide surfaces GS11, GS12, while restricting the displacement of the connector 100 in the perpendicular direction D3 with the first contact portion 245 and the second contact portion 246.

By achieving both double-sided contact by first contact surface 113 and second contact surface 114 and support of multiple contacts 110 by contact support portion 141, the strength of connector 100 can be improved.

[0083] (6) A connector system 1 described in (5), in which each of the multiple contacts 110 is formed from a plate material P1 along the arrangement direction D2 and the mating direction D1, and the second convex portion 115 is formed by folding back the plate material P1 and partially overlapping it.
