[0009] [Description of the embodiments of the present disclosure] The following describes exemplary embodiments of the present disclosure. The following exemplary features [1] to [6] may be combined in any combination without causing any inconsistency. [1] The connector of the present disclosure includes an outer conductor, a housing that accommodates the outer conductor, and an inner conductor that is disposed inside the outer conductor, the outer conductor having a cylindrical main body with openings at the front and rear, a back plate that is disposed so as to be displaceable from an open state that opens the rear opening of the main body to a closed state that closes the rear opening of the main body, and side plate portions that protrude from the left and right ends of the back plate, the main body having inner plate portions disposed at the left and right ends, the inner plate portions disposed so as to contact the inner surfaces of the side plate portions in the left and right direction in the closed state of the back plate, and the housing having a pressing portion that presses the side plate portions against the inner plate portions. Since the side plate portions are pressed against the inner plate portions by the pressing portions of the housing, the connection state between the side plate portions and the inner plate portions can be maintained, and the shielding performance of the outer conductor can be stabilized.

[0010] [2] In the connector described in [1] above, it is preferable that the pressing portion has a wall portion covering the outer surface of the side plate portion in the left-right direction, and a pressing main body portion protruding from the wall portion and contacting the outer surface of the side plate portion. By adjusting the forming position and forming range of the pressing main body portion on the wall portion, the connection state between the side plate portion and the inner plate portion can be more appropriately maintained.

[0011] [3] In the connector described in [2] above, it is preferable that the side plate portion has a base end portion, a locking portion, and a tip portion formed in sequence from the back plate portion side to the tip portion in the protruding direction, and the pressing body portion is configured to contact at least the outer surface of the tip portion. If the side plate portion opens outward to the left and right with the base end portion connected to the back plate portion as a fulcrum, the tip portion will be displaced outward to the left and right more than the base end portion. In contrast, the configuration of [3] above has the pressing body portion contacting the outer surface of the tip portion, so that the tip portion can be prevented from displacing outward to the left and right. As a result, the side plate portion can be effectively prevented from opening outward to the left and right, and the connection state between the side plate portion and the inner plate portion can be more properly maintained.

[0012] [4] In the connector described in [3] above, it is preferable that the pressing body has a rib shape extending in the front-rear direction sandwiching the locking portion and is configured to contact the outer surface of the base end and the outer surface of the tip end. Since the tip end and the base end can be prevented from being displaced outward to the left and right, the locking portion formed between the tip end and the base end can stably maintain a state in which it locks the inner plate portion.

[0013] [5] In the connector according to any one of [1] to [4] above, it is preferable that the main body has a cylindrical connecting portion disposed forward of the inner plate portion, and a slit formed between the cylindrical connecting portion and the inner plate portion, and the side plate portion is disposed so as to be contained within a range of the inner plate portion in the front-rear direction. According to this configuration, it is possible to realize a state in which the inner surface of the side plate portion is in contact only with the inner plate portion, so that the connection state between the side plate portion and the inner plate portion can be more appropriately maintained.

[0014] [6] In the connector according to any one of [1] to [5] above, it is preferable that the side plate has a side ground pin connected to the circuit board. With this configuration, a ground current can be passed from the side plate to the circuit board, so that the shielding performance can be improved compared to when the side plate does not have a side ground pin.

[0015] [Details of the embodiment of the present disclosure] The present disclosure will be described below with reference to the drawings. The present disclosure is not limited to these examples, but is defined by the claims, and includes all modifications within the meaning and scope of the claims.

[0016] [Embodiment 1] As shown in Figs. 1 and 2, the connector 10 includes a housing 20, an outer conductor 30, a dielectric 50, and an inner conductor 60. The housing 20 can be fitted to a mating housing (not shown). In the first embodiment, the width direction of the connector 10 is the left-right direction, and the fitting direction of the housing 20 and the mating housing is the front-rear direction. The height direction of the connector 10 is synonymous with the up-down direction. In Figs. 2 and 4-9, "front side" is represented by "F", in Figs. 1-4, 7 and 8, "upper side" is represented by "U", and in Figs. 1, 3-6 and 9, "right side" is represented by "R". The directional references are for convenience and do not necessarily coincide with the directional references when the connector 10 is mounted on a vehicle (not shown) or the like. In the following description, the "inner side" refers to the side facing the center of the connector 10, and the "inner side" refers to the "inner" surface. For example, the inner side in the left-right direction is the side facing the center of the connector 10 in the left-right direction, and the inner side in the left-right direction is the surface facing the center of the connector 10 in the left-right direction. The "outer side" refers to the side away from the center of the connector 10, and the "outer surface" refers to the "outside" surface. For example, the outer side in the left-right direction is the side away from the center of the connector 10 in the left-right direction, and the outer surface in the left-right direction is the surface facing the side away from the center of the connector 10 in the left-right direction.

[0017] The outer conductor 30 is formed, for example, by bending a conductive metal plate. As shown in Figs. 7 and 8, the outer conductor 30 has a square tube-shaped main body 31 extending in the front-rear direction. The front and rear surfaces of the main body 31 are open to the front and rear, respectively. The main body 31 is formed by a bottom 33 forming the lower side of the square tube, a top 35 forming the upper side, a pair of side portions 37 forming both sides, and a pair of inner plate portions 39 extending downward from both side surfaces at the rear end sides of the pair of side portions 37. The inner plate portion 39 has a thickness in the left-right direction and is plate-shaped. The inner plate portion 39 has a pair of locking receiving portions 41 that protrude downward at both front and rear ends. A space portion 43 that has a rectangular recess shape when viewed from the side is formed between the pair of locking receiving portions 41. The main body 31 has a cylindrical connecting portion 32 in front of the inner plate portion 39. A slit 45 extending in the up-down direction is formed between the front lock receiving portion 41 of the inner plate portion 39 and the tubular connecting portion 32. The tubular connecting portion 32 can be easily bent into a square tube shape by interposing the slit 45 between it and the flat inner plate portion 39. The slits 45 are formed in pairs at both left and right ends of the rear end portion of the tubular connecting portion 32.

[0018] The outer conductor 30 has a back plate portion 47 that is displaceable from an open state (see FIG. 8) that opens the opening on the rear surface of the main body portion 31 to a closed state (see FIG. 7) that closes the opening on the rear surface of the main body portion 31 with respect to the main body portion 31. In addition, as shown in FIG. 8, the outer conductor 30 has a flexible bent portion 49 that connects the back plate portion 47 and the top portion 35. The bent portion 49 is formed between the back plate portion 47 and the top portion 35 along the left-right direction. For example, the bent portion 49 extends linearly in the front-rear direction, so that the back plate portion 47 can be disposed horizontally in the open state. The bent portion 49 is bent in a circular manner, so that the back plate portion 47 can be disposed vertically in the closed state. In this manner, the back plate portion 47 can be rotated between the open state and the closed state with respect to the main body portion 31 via the bent portion 49. As shown in FIG. 8 and FIG. 9, when the back plate portion 47 is in the closed state, the outer conductor 30 forms an opening 36 having a rectangular opening shape in a bottom view between the back plate portion 47, each of the inner plate portions 39, and the bottom portion 33. The dielectric 50 is drawn out from the opening 36 downward (to the side where a circuit board 90 described later is located).

[0019] The outer conductor 30 has a pair of side plate portions 51 protruding from both left and right ends of the back plate portion 47. The pair of side plate portions 51 are plate-shaped and are arranged with their plate surfaces facing the left and right direction. In the open state, each side plate portion 51 protrudes downward from both left and right ends of the back plate portion 47. In the closed state, each side plate portion 51 protrudes forward from both left and right ends of the back plate portion 47. In the closed state, the back plate portion 47 has a pair of rear ground pins 54 extending downward from both left and right ends of the lower edge of the main body portion. Each rear ground pin 54 is fixed by soldering to a through hole formed in the circuit board 90.

[0020] The side plate portion 51 has a base end portion 53, a locking portion 55, and a tip portion 57. As shown in FIG. 7, the locking portion 55 has a locking main body portion 59 and a notch portion 61. The locking main body portion 59 forms the front end side of the locking portion 55. As shown in FIG. 6, the locking main body portion 59 is formed so as to be curved inward toward the rear when viewed from above. As shown in FIG. 7, the outer edge of the locking main body portion 59 has a semicircular arc shape with the front curved when viewed from the side. The outer edge of the notch portion 61 has a rectangular shape extending in the up-down direction when viewed from the side, and forms the rear end side of the locking portion 55. The notch portion 61 penetrates the side plate portion 51. As shown in FIG. 6, the locking main body portion 59 is arranged in the space portion 43 of the inner plate portion 39 in the closed state. The locking main body 59 is accommodated in the space 43 by abutment between a rear end surface 59S of the locking main body 59 and a front end surface 41S of the locking receiving portion 41 that is located at the rear of the pair of locking receiving portions 41. The side plate 51 and the inner plate 39 are locked together, so that the back plate 47 can be held in a closed state relative to the main body 31. When the back plate 47 is in the closed state, the side plate 51 covers the area from the rear end of the inner plate 39 to the rear end of the slit 45 from the outside. In other words, the side plate 51 is positioned so as to be contained within the formation range of the inner plate 39 in the front-rear direction.

[0021] 7, the base end 53 is a portion located on the rear end side (back plate 47 side) of the locking portion 55. Specifically, the base end 53 is a portion of the side plate 51 between the rear end edge of the side plate 51, the rear end edge of the cutout portion 61, and the extension line T1 of the rear end edge. The tip portion 57 is a portion located on the front end side of the locking portion 55. Specifically, the tip portion 57 is a portion of the side plate 51 between the tangent line T2 to the front end of the locking main body portion 59 and the front end edge of the side plate 51.

[0022] As described above, the base end 53, the locking portion 55 and the tip end 57 are formed by dividing the rectangular main body portion of the side plate portion 51 into three portions, front and rear, as viewed from the side. The side plate portion 51 has a side ground pin 63 extending downward from the center of the front and rear at the lower edge of the main body portion. The side ground pin 63 is fixed by soldering to a through hole formed in the circuit board 90.

[0023] As shown in FIG. 7, the outer conductor 30 has a front plate portion 65 bent downward from the rear end of the bottom portion 33. The front plate portion 65 has a rectangular plate shape when viewed from the front. As shown in FIG. 9, the front plate portion 65 has a pair of front ground pins 67 extending downward from both left and right ends of the lower end edge. The pair of front ground pins 67 are fixed by soldering to through holes formed in the circuit board 90. The front ground pins 67 are arranged symmetrically with respect to the front plate portion 65. In this disclosure, the ground pin refers to the front ground pin 67, the rear ground pin 54, and the pair of side ground pins 63. Each of the ground pins (54, 63, 67) is electrically connected to a conductive portion for grounding of the circuit board 90. Each of the ground pins (54, 63, 67) is arranged so as to surround the periphery of the inner conductor 60 when viewed from below the outer conductor 30. The ground pins (54, 63, 67) are disposed symmetrically with respect to a line segment H2 that extends in the front-rear direction through the center of the distance D between the centers of the two inner conductors 60.

[0024] The inner conductor 60 is formed by bending a conductive metal plate or the like. As shown in Fig. 2, the inner conductor 60 has an overall L-shape and has a mating connection part 62 extending in the front-rear direction and a board connection part 69 extending in the up-down direction. The mating connection part 62 is electrically connected to a mating terminal fitting (not shown) of the mating connector by fitting the connector 10 with the mating connector. The board connection part 69 is fixed by soldering to a through hole formed in the circuit board 90. The board connection part 69 is electrically connected to a signal conductive part of the circuit board 90.

[0025] The dielectric 50 is made of an insulating synthetic resin material, and has a terminal accommodating chamber 52 penetrating therein in the front-rear direction, as shown in Fig. 2. An inner conductor 60 is press-fitted into the terminal accommodating chamber 52. The inner conductor 60 is held by the dielectric 50 with a mating connecting portion 62 protruding forward from the front end opening of the terminal accommodating chamber 52. The inner conductor 60 and the outer conductor 30 are kept in an insulated state by the dielectric 50.

[0026] 2 and 4, the housing 20 is made of synthetic resin and has a base wall portion 21 arranged with its wall surface facing in the front-rear direction, a square cylindrical hood portion 23 protruding forward from the outer periphery of the base wall portion 21, and a pair of side wall portions 24 protruding rearward from both left and right ends of the base wall portion 21. The pair of side wall portions 24 have a pair of walls 28 at their lower ends which are formed to be thinner than their upper ends.

[0027] 2, the hood portion 23 has a housing lock portion 26 on the inner surface of the upper wall. A mating connector is fitted into the hood portion 23. The housing lock portion 26 has the role of engaging the mating connector inside the hood portion 23 with a lock arm (not shown) to hold the two connectors in a fitted state.

[0028] As shown in Figs. 1 and 2, the base wall 21 has an attachment hole 27 penetrating in the front-rear direction (wall thickness direction of the base wall 21). A part of the main body 31 of the outer conductor 30 is inserted and held in the attachment hole 27 of the base wall 21. A front part of the tubular connection part 32 protrudes into the hood part 23. The housing 20 has an accommodation space 22 that is open to the rear, behind the base wall 21 and between the side walls 24. A part of the outer conductor 30 that protrudes rearward from the attachment hole 27 (hereinafter referred to as "the rear part of the outer conductor 30") is disposed in the accommodation space 22, and is covered and protected on both the left and right sides by the side walls 24. When the outer conductor 30 is accommodated in the housing 20, the front end surface of the inner plate part 39 is disposed so as to be able to abut against the rear surface of the base wall 21, and defines the position of the outer conductor 30 in the front direction.

[0029] The inner surface of each wall portion 28 faces the accommodating space 22. The inner surface of each wall portion 28 is a vertical surface along the front-rear and up-down directions. With the rear portion of the outer conductor 30 disposed in the accommodating space 22, the inner surface of each wall portion 28 is disposed so as to face the outer surface of each side plate portion 51 of the outer conductor 30. The outer surface of each side plate portion 51 is covered by each wall portion 28. Each side plate portion 51 can be pressed inward, where the inner plate portion 39 is located, by a pressing portion 40 provided on each wall portion 28. The pressing portion 40 is formed by each wall portion 28 and a plurality of pressing main bodies 70 protruding from the inner surface of each wall portion 28. Each pressing main body 70 is shaped like a rib extending in the front-rear direction. The cross-sectional shape of each pressing main body 70 is curved. The curved apex of each pressing main body 70 contacts the outer surface of each side plate portion 51. The portion where each pressing main body 70 contacts the outer surface of each side plate portion 51 becomes the pressing portion of the pressing portion 40 against each side plate portion 51.

[0030] The front end of each pressing main body 70 is integrally connected to the rear surface of the base wall portion 21. The rear end of each pressing main body 70 is disposed forward of the rear end of each wall portion 28. The rear end of each pressing main body 70 forms a tapered portion 73, which is a surface that tapers inwardly as it approaches the front. During the process of assembling the outer conductor 30, each side plate portion 51 moves along the tapered portion 73 of each pressing main body 70, and is smoothly accommodated in the accommodation space 22 between each wall portion 28. The pressing main bodies 70 are arranged in pairs in the vertical direction on each wall portion 28. The pressing main bodies 70 that form a pair in the vertical direction are arranged at height positions corresponding to the locking portions 55 of the side plate portions 51. Of the pressing main bodies 70 that form a pair in the vertical direction, the pressing main body that is arranged at the top is configured as an upper rib 71 that can come into contact with the upper end portion of the outer surface of the side plate portion 51. Of the pressing main bodies 70 that form a pair in the vertical direction, the pressing main body that is arranged at the bottom is configured as a lower rib 72 that can come into contact with the upper and lower middle portions of the outer surface of the side plate portion 51.

[0031] As shown in FIG. 8, the rear end of the main body 31 has a pair of main body side locking holes 75 (only one shown) that are rectangular and open in the left-right direction and are long in the up-down direction, at the center of the pair of side parts 37 in the up-down direction. The main body side locking hole 75 is disposed rearward of the slit 45. The main body 31 has a pair of outer locking parts 77 in front of each main body side locking hole 75. The main body 31 has a pair of inner locking parts 79 in rear of each main body side locking hole 75. The outer locking parts 77 are formed by bending the side parts 37 of the main body 31 outward in the left-right direction through the main body side locking hole 75, and are formed in a generally triangular claw shape in side view. Each outer locking part 77 locks the base wall part 21, so that the outer conductor 30 that has passed through the mounting hole 27 is held and fixed to the housing 20. Each inner locking portion 79 is formed by bending inward in the left-right direction through a body side locking hole 75 in the side portion 37 of the body portion 31, and is formed in a generally triangular claw shape in side view. The inner locking portion 79 is slightly smaller in shape than the outer locking portion 77. Both inner locking portions 79 lock the dielectric 50, so that the dielectric 50 is held and fixed inside the body portion 31.

[0032] As shown in Fig. 4, a pair of fixing metal fittings 80 are press-fitted into the outer surfaces of the left and right sides of the hood portion 23. The fixing metal fittings 80 have press-fit projections 83 that protrude in the front-rear direction at their upper ends. The press-fit projections 83 are inserted into and locked in the press-fit recesses 25 of the housing 20. The fixing metal fittings 80 have board connection pins 81 that extend downward at their lower ends. The board connection pins 81 are fixed by soldering into fixing holes formed in the circuit board 90.

[0033] [Effects of Connector 10] Next, an example of a procedure for assembling the connector 10 of the first embodiment will be described. When the back plate portion 47 is in the open state, the dielectric 50 with the inner conductor 60 inserted therein is inserted inside the outer conductor 30. Next, the back plate portion 47 is rotated and displaced from the open state to the closed state via the bent portion 49. In the process of displacing the back plate portion 47 to the closed state, the locking main body portions 59 of the locking portions 55 on the pair of side portions 37 interfere with the corresponding locking receiving portions 41, and the pair of side plate portions 51 are expanded and deformed (elastically deformed) outward with the connection portions with the back plate portion 47 as fulcrums.

[0034] When the back plate portion 47 reaches the closed state, the rear opening of the main body portion 31 is closed by the back plate portion 47, and the pair of side plate portions 51 that have returned to their original elastic state cover from the outside the entire lock receiving portion 41 of the corresponding inner plate portion 39. The front end surface 41S of the lock receiving portion 41 arranged on the rear side and the rear end surface 59S of the lock main body portion 59 are arranged to be able to abut against each other in an opposed manner. This prevents the back plate portion 47 from returning to the open state and being displaced, and the box shape of the outer conductor 30 is maintained.

[0035] Next, the main body 31 of the outer conductor 30 is inserted from the rear into the mounting hole 27 of the base wall 21 of the housing 20 and held therein. The rear part of the outer conductor 30 is accommodated in the accommodation space 22. The inner plate 39 and the side plate 51 are covered by the respective walls 28 of the housing 20. As shown in FIG. 3, each pressing main body 70 of the pressing part 40 abuts on the outer surface of the side plate 51 of the outer conductor 30. As a result, an inward pressing force is applied to each side plate 51, and each side plate 51 is firmly pressed against the outer surface of each inner plate 39. As a result, the inner surface of each side plate 51 and the outer surface of each inner plate 39 are in surface or point contact with each other, except for the engagement portion between the engagement portion 55 and the engagement receiving portion 41.

[0036] In the case of the first embodiment, the pressing portion of the pressing portion 40 for each side plate portion 51 is provided over the entire area or a range close to the entire area of ​​each side plate portion 51 in the front-rear direction. Specifically, the pressing portion of the pressing portion 40 for each side plate portion 51 is provided at the upper end and the vertical middle part of the tip portion 57 of each side plate portion 51, and at the upper end and the vertical middle part of the base end portion 53 of each side plate portion 51. Also, each pressing main body portion 70 is arranged so as to be able to partially contact the outer surface of the locking portion 55. In particular, the tip portion 57 of the side plate portion 51 is located far from the connecting portion between the side plate portion 51 and the back plate portion 47, and therefore is easily separated from the outer surface of the inner plate portion 39. The pressing main body portion 70 pressing from the rear end to the front end of the tip portion 57 can effectively maintain the contact state between the side plate portion 51 and the inner plate portion 39. Maintaining the contact state between the side plate portion 51 and the inner plate portion 39 is synonymous with maintaining an electrical connection state between the side plate portion 51 and the inner plate portion 39 .

[0037] The tapered portion 73 formed at the rear end of the pressing body 70 allows the side plate portion 51 of the outer conductor 30 to be smoothly inserted into the accommodating space 22 of the housing 20 without rattling. The tapered portion 73 is formed only at the rear end of the pressing body 70, so it does not prevent pressing against the front end 57. As shown in FIG. 3, the upper rib 71 presses the upper side of the side plate portion 51. As shown in FIG. 5, the upper rib 71 presses the smooth upper end of the side plate portion 51 from the rear end to the front end in the front-rear direction without any gaps. The upper rib 71 maintains stable contact between the side plate portion 51 and the inner plate portion 39.

[0038] As shown in FIG. 6, the lower rib 72 presses from the base end 53 to the tip end 57 in the front-rear direction. The lower rib 72 also presses the vertical center of the locking body 59 and the notch 61 in the front-rear direction. The lower rib 72 protrudes inward from the inner surface of the wall 28. The portion where the locking body 59 and the notch 61 are formed is the portion where the side plate 51 and the inner plate 39 are locked. The lower rib 72 presses the above portion, so that the locking body 59 is reliably fixed in the space 43 of the inner plate 39. As shown in FIG. 7, the side plate 51 contacts the inner plate 39 in the range from the rear edge of the inner plate 39 to the rear edge of the slit 45. This makes it possible to prevent the current flowing from the body 31 of the outer conductor 30 to each ground pin (54, 63, 67) from detouring.

[0039] The upper rib 71 and the lower rib 72 both press against the tip 57 of the side plate portion 51. The tip 57 of the side plate portion 51 is a location that is particularly likely to separate from the inner plate portion 39 due to vibration or the like. By pressing the tip 57 of the side plate portion 51, the side plate portion 51 can be effectively prevented from separating from the inner plate portion 39.

[0040] After the outer conductor 30 is inserted into the housing 20, the connector 10 is placed on the surface of the circuit board 90. Specifically, the board connection pin 81 of the fixing bracket 80 press-fitted into the housing 20 is fixed to the through hole of the circuit board 90 by soldering. The board connection portion 69 of the inner conductor 60 is conductively connected to the through hole of the circuit board 90 by soldering. The tip of each ground pin (54, 63, 67) is conductively connected to a ground circuit formed on the surface of the circuit board. Here, each ground pin (54, 63, 67) is arranged so as to surround the board connection portion 69. As shown in FIG. 9, each ground pin (54, 63, 67) is arranged symmetrically with respect to a line segment H2 that extends in the front-rear direction through the center of the width direction of the outer conductor 30. The line segment H2 passes through the center of the gap D formed between the board connection portions 69. The inner conductor 60 and each ground pin (54, 63, 67) extend in parallel in the vertical direction toward the circuit board side.

[0041] In the connector 10 of the first embodiment, the outside of the inner plate portion 39 and the inside of the side plate portion 51 are in contact with each other without any gaps in the front-rear direction by the pressing of the pressing body portion 70. As a result, the current path of the current flowing from the outer conductor to each ground pin (54, 63, 67) does not detour. The current that does not detour along the current path prevents electric field leakage of the signal line generated by the inner conductor 60. Therefore, the connector 10 can improve the shielding performance of the signal line conducted to the inner conductor 60 by the current flowing from the outer conductor to each ground pin (54, 63, 67). In addition, each ground pin (54, 63, 67) is arranged symmetrically with respect to the inner conductor 60. Specifically, each ground pin (54, 63, 67) is arranged symmetrically with respect to the line segment H2. Compared to the case where each ground pin (54, 63, 67) is arranged asymmetrically with respect to the inner conductor 60, the electric field leakage of the signal line conducting to the inner conductor 60 is effectively suppressed by the current flowing through the ground pins (54, 63, 67), thereby improving the shielding performance for the signal line.

[0042] The connector 10 of the first embodiment includes an outer conductor 30, a housing 20 that accommodates the outer conductor 30, and an inner conductor 60 disposed inside the outer conductor 30. The outer conductor 30 has a cylindrical main body 31 that is open at the front and rear. The outer conductor 30 has a back plate 47 that is displaceably connected to the main body 31 from an open state that opens the rear opening of the main body 31 to a closed state that closes the rear opening of the main body 31. The outer conductor 30 has side plate portions 51 that protrude from both left and right ends of the back plate 47. The main body 31 has inner plate portions 39 that are disposed at both left and right ends. The pair of inner plate portions 39 are disposed so as to contact the inner surfaces of the pair of side plate portions 51 in the left and right direction when the back plate portion 47 is in the closed state. The housing 20 has a pressing portion 40 that presses the side plate portions 51 against the inner plate portions 39 when the back plate portion 47 is in the closed state. According to this configuration, the side plate portion 51 is pressed against the inner plate portion 39 by the pressing portion 40 of the housing 20, so that the connection between the side plate portion 51 and the inner plate portion 39 can be maintained, and the shielding performance of the outer conductor 30 can be stabilized.

[0043] In the connector 10 of the first embodiment, the pressing portion 40 has a wall portion 28 that covers the outer surface of the side plate portion 51 in the left-right direction, and a pressing main body portion 70 that protrudes from the wall portion 28 and contacts the outer surface of the side plate portion 51. By adjusting the forming position and forming range of the pressing main body portion 70 on the wall portion 28, the connection state between the side plate portion 51 and the inner plate portion 39 can be maintained more appropriately.

[0044] In the connector 10 of the first embodiment, the side plate portion 51 has a locking portion 55 that locks the inner plate portion 39. The side plate portion 51 is formed with a base end portion 53, a locking portion 55, and a tip portion 57, which are arranged in sequence from the back plate portion 47 side to the tip in the protruding direction. The locking portion 55 locks the inner plate portion 39. In the connector 10, the pair of pressing main bodies 70 are configured to contact at least the outer surface of the tip portion 57. According to this configuration, if the side plate portion 51 opens outward to the left and right with the base end portion 53 side portion connected to the back plate portion 47 as a fulcrum, the tip portion 57 will be displaced outward to the left and right more than the base end portion 53. In contrast, in this configuration, the pressing main body portion 70 contacts the outer surface of the tip portion 57, so that the tip portion 57 can be prevented from being displaced outward to the left and right. As a result, the side plate portions 51 can be effectively prevented from opening outward to the left or right, and the connection state between the side plate portions 51 and the inner plate portions 39 can be maintained more appropriately.

[0045] In the connector 10 of the first embodiment, the pressing bodies 70 are arranged at intervals in the vertical direction on the wall portion 28. According to this configuration, the pressing bodies 70 can press the side plate portion 51 at different positions at intervals in the vertical direction, so that it is possible to prevent any end portion of the side plate portion 51 in the vertical direction from being displaced in a direction away from the inner plate portion 39.

[0046] In the connector 10 of the first embodiment, the pressing body 70 has a rib shape extending in the front-rear direction sandwiching the locking portion 55, and is configured to contact the outer surface of the base end 53 and the outer surface of the tip end 57. This configuration can prevent the tip end 57 and the base end 53 from being displaced outwardly to the left or right.

[0047] In the connector 10 of the first embodiment, the main body 31 has a tubular connecting portion 32 disposed forward of the inner plate 39, and a slit 45 formed between the tubular connecting portion 32 and the inner plate 39, and it is preferable that the side plate 51 is disposed so as to be contained within the range in which the inner plate 39 is formed in the front-rear direction. According to this configuration, a state in which the inner surface of the side plate 51 is in contact only with the inner plate 39 can be realized, so that the connection state between the side plate 51 and the inner plate 39 can be more appropriately maintained.

[0048] In the connector 10 of the first embodiment, the side plate portion 51 has a lateral ground pin 63 connected to the circuit board 90. According to this configuration, a ground current can be passed from the side plate portion 51 to the circuit board 90, and therefore, compared to a case in which the side plate portion 51 does not have the lateral ground pin 63, the shielding performance can be improved.

[0049] [Another embodiment of the present disclosure] The present disclosure is not limited to the embodiments described above and shown in the drawings, but is indicated by the claims. The present disclosure includes the equivalent meaning of the claims and all modifications within the scope of the claims, including the following embodiments. (1) The connector 10 of the first embodiment has a total of six ground pins (54, 63, 67). The number of ground pins is not limited as long as they are symmetrical with respect to a center line that extends in the front-rear direction through the center of the inner conductor. (2) The ground pins (54, 63, 67) and the board connection portion 69 of the connector 10 of the first embodiment pass through through holes formed in the circuit board 90. The ends of each ground pin and the board connection portion may be of a surface mount type. (3) Although the main body 31 of the connector 10 in the first embodiment has a rectangular cylindrical shape, it may have a round cylindrical shape. (4) Although the back plate portion 47 of the outer conductor 30 in the first embodiment is connected to the main body portion 31, the back plate portion may be a separate member that is removable from the outer conductor. (5) In embodiment 1, a pair of fastening members 80 are press-fitted into the outer surfaces of both the left and right sides of the hood portion 23 of the housing 20. However, the shape of the housing is not limited thereto, and for example, a configuration may be adopted in which fastening members are not used. (6) In the first embodiment, the inner conductor 60 and the ground pins (54, 63, 67) extend parallel to the circuit board 90, but the inner conductor and the ground pins do not have to be parallel as long as they extend in the same direction side by side. For example, the ground pins may be configured to extend at an angle toward the circuit board rather than perpendicularly. (7) The locking portion 55 of the first embodiment is formed by a locking body 59 having a semicircular arc shape with a curved front when viewed from the side, and a notch 61 having an outer edge that is substantially rectangular when viewed from the side. The shape of the locking portion is not limited. For example, the shape of the locking body may be substantially rectangular, or may not have a notch. In addition, the locking portion may have a known locking configuration. (8) Although the pressing body 70 protrudes from the inner surface of the wall 28 in the first embodiment, it is not necessary to provide a pressing body. For example, the inner surface of the wall may directly press the side plate. (9) In the first embodiment, the lower rib 72 covers a portion of the engaging portion 55, but the lower rib does not necessarily have to contact the engaging portion. (10) In embodiment 1, slit 45 is shaped so that side portion 37 is cut out in a semicircular arc shape toward the inside, but the shape of the slit is not limited to this. For example, the slit may be shaped so that the side panel is cut out inward at an acute angle. (11) The pressing body 70 of embodiment 1 has an upper rib 71 that presses the upper end of the side plate 51 and a lower rib 72 that presses the locking portion 55 of the side plate 51, but a separate pressing body may be provided that presses a position spaced downward from the locking portion. (12) The pressing body 70 in the first embodiment has an inwardly bulging arc shape when viewed from the rear, and extends along the inner wall surface of the wall portion 28 from the front to the rear end, but the pressing body may be formed to be scattered on the front and rear of the inner wall surface. The pressing body may also be in the form of a rectangular column protruding inward when viewed from the rear. The pressing body may not be ribbed, but may be, for example, in the form of a boss protruding. (13) In the first embodiment, the walls 28 are formed parallel to the left-right direction of the housing 20 so as to extend perpendicular to the up-down direction, but the walls do not have to be formed so as to extend perpendicular to the up-down direction of the housing. For example, the walls may be inclined upward so as to narrow the distance between them. (14) In the first embodiment, the pressing body 70 is configured to contact the outer surface of each of the tip end 57 and the base end 53. The pressing body 70 may be configured to contact only the outer surface of the tip end. (15) In the first embodiment, the curved apex of the pressing main body 70 is in contact with the outer surface of each side plate 51 when viewed from the rear while the pressing main body 70 is inserted into the housing 20, and is deformed into a flat shape. The curved apex of the pressing main body may be deformed in any manner. Also, the side plate may be configured to deform while the pressing main body 70 is inserted into the housing. (16) The pressing main body portions 70 of the first embodiment are arranged in pairs at a distance from each other in the vertical direction on the wall portion 28. There is no limitation on the number of pressing main bodies, and one pressing main body portion may be provided for one wall portion. [Explanation of symbols]
