Summary of the Invention

Problems to be Solved by the Invention

[0004] In the connector of Patent Document 1, when the mating connector is fitted in an oblique posture (twisted fitting) with respect to the normal fitting direction, since the corner portion at the front end of the housing is angular, there is a risk of entering the mating housing and contacting the mating terminal (risk of twisting of the terminal). In that case, it is assumed that the mating terminal is damaged by the corner portion at the front end of the housing.

[0005] Therefore, an object of the present disclosure is to provide a connector and a connector device that can suppress twisting of a mating terminal.

Means for Solving the Problems

[0006] The connector of this disclosure comprises a housing having a rectangular tubular hood portion, wherein at least one of the four corners at the front end of the hood portion is provided with a chamfered portion. [Effects of the Invention]

[0007] According to this disclosure, it is possible to provide a connector and a connector device that can suppress twisting of the mating terminal. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The connector disclosed herein is (1) A housing having a rectangular tubular hood section, A chamfered portion is provided on at least one of the four corners at the front end of the hood portion. According to the configuration described in (1) above, when prying mating with the mating connector (mating in a position where it approaches at an oblique angle to the normal mating direction), the chamfered portion makes it difficult for the front corner of the hood portion to come into contact with the mating terminal. This makes it easier to prevent prying of the mating terminal as it approaches so that the front corner of the hood portion comes into contact with the mating terminal.

[0010] (2) In the connector described in (1) above, it is preferable that the chamfered portion has a C-shaped surface. According to the configuration of (2), even if the chamfered surface comes into contact with the mating terminal, the chamfered surface is more likely to make surface contact with the mating terminal, making it less likely to damage the mating terminal.

[0011] (3) In the connector described in (2) above, it is preferable that the C surface is connected to the front end surface of the hood portion without any step difference. According to the configuration of (3), there are no steps or other irregularities on the side of the housing into which the mating terminal is inserted, making it less likely for the mating terminal to be damaged.

[0012] (4) In the connector described in any of (1) to (3) above, it is preferable that the housing has a recess that is recessed along at least a part of the outer edge of the chamfered portion. According to the configuration of (4), the outer edge of the chamfered portion is recessed inward, making it less likely for the housing to damage the mating terminal.

[0013] (5) In the connector described in any of (1) to (4) above, it is preferable that the chamfered portion is provided on each of the four corners of the hood portion. According to the configuration of (5), chamfered edges are provided at each of the four corners, which prevents twisting of the mating terminals in accordance with various mating configurations between connectors.

[0014] (6) In the connector described in any of (1) to (5) above, it is preferable that the connector comprises a dielectric that houses an inner conductor and an outer conductor that houses the dielectric, and the housing houses the outer conductor. (6) According to the configuration, the shielding performance of the inner conductor by the outer conductor can be enhanced.

[0015] (7) A connector device including the connector according to any one of (1) to (6) above and a mating connector that fits into the connector, wherein the mating connector includes a mating shield terminal housed in a mating housing, and the mating shield terminal has a mating inner conductor, a mating dielectric that houses the mating inner conductor, and a mating outer conductor that houses the mating dielectric, and the mating outer conductor is exposed in the mating housing. (7) According to the configuration, in the configuration where the mating outer conductor is exposed in the mating housing, there is an advantage that it is easier to prevent the mating terminal from jamming by providing a chamfer portion at the corner.

[0016] [Details of Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to this exemplification, and is intended to be defined by the claims and to include all modifications within the meaning and scope equivalent to the claims.

[0017] [Embodiment 1] The connector device C (see FIG. 8) includes the connector 10 shown in FIGS. 1 and 2 and a mating connector 100 (see FIGS. 4 and 5) that fits into the connector 10. The connector 10 and the mating connector 100 are configured as shield connectors. The connector 10 is a male connector. The mating connector 100 is a female connector.

[0018] In this embodiment 1, the front-to-back direction relative to connector 10 is defined as the F direction in Figure 1. The left-to-right direction relative to connector 10 is defined as the R direction in Figure 1. The up-to-down direction relative to connector 10 is defined as the H direction. The front-to-back direction relative to the mating connector 100 is defined as the F direction in Figure 4. The left-to-right direction relative to the mating connector 100 is defined as the R direction in Figure 4. The up-to-down direction relative to the mating connector 100 is defined as the H direction in Figure 4.

[0019] (Connector configuration) As shown in Figure 3, the connector 10 is constructed by assembling a first terminal module 20, a second terminal module 30, an outer conductor 40, a housing 50, and a connecting member 60.

[0020] As shown in Figure 3, the first terminal module 20 is configured to include an L-shaped first inner conductor 21 and an L-shaped first dielectric 22 that houses the first inner conductor 21. The first inner conductor 21 corresponds to the "inner conductor" in this disclosure. The first dielectric 22 corresponds to the "dielectric" in this disclosure. The first dielectric 22 has a first mounting-side surrounding portion 23 that extends in the vertical direction and a first mating-side surrounding portion 24 that protrudes forward from the upper end of the first mounting-side surrounding portion 23. The second terminal module 30 is configured to include an L-shaped second inner conductor 31 and an L-shaped second dielectric 32 that houses the second inner conductor 31. The second inner conductor 31 corresponds to the "inner conductor" in this disclosure. The second dielectric 32 corresponds to the "dielectric" in this disclosure. The second dielectric 32 has a second mounting-side surrounding portion 33 that extends in the vertical direction, and a second fitting-side surrounding portion 34 that protrudes forward from the upper end of the second mounting-side surrounding portion 33.

[0021] The outer conductor 40 is constructed by assembling an upper case 70 and a lower case 80. The upper case 70 is a single metal part formed by forging or casting. The upper case 70 has a box-shaped housing section 71, a first cylindrical section 72, and a second cylindrical section 73. The box-shaped housing section 71 is a rectangular shape with its rear and bottom surfaces open. A protrusion 74 is formed in the rectangular area of ​​the front surface of the box-shaped housing section 71, excluding the upper edge and both left and right side edges. The area of ​​the front surface of the box-shaped housing section 71 that sandwiches the protrusion 74 from both the left and right sides functions as a receiving surface 75.

[0022] The front surface of the projection 74 functions as a rear opposing surface 76, which is a plane parallel to the receiving surface 75. The first cylindrical portion 72 has its axis oriented in the front-rear direction and is a portion that protrudes forward from the rear opposing surface 76. The second cylindrical portion 73 has its axis oriented parallel to the first cylindrical portion 72 and is a portion that protrudes forward from the rear opposing surface 76 below the first cylindrical portion 72. The lower end of the first cylindrical portion 72 and the upper end of the second cylindrical portion 73 are connected via a connecting portion 77 along the entire length from the front end to the rear end. The first cylindrical portion 72, the second cylindrical portion 73, and the connecting portion 77 form a figure-eight shape in a front view.

[0023] As shown in Figure 3, the connecting portion 77 is narrower than the first cylindrical portion 72 and the second cylindrical portion 73, so a pair of constricted portions 78 are formed between the first cylindrical portion 72 and the second cylindrical portion 73.

[0024] The lower case 80 is a single metal part formed by forging or casting. As shown in Figure 3, the lower case 80 has a bottom wall portion 81, a closing portion 82, and a pair of left and right retaining portions 83. The bottom wall portion 81 has a first through hole 84 and a second through hole 85 that penetrate the bottom wall portion 81 in the vertical direction. The second through hole 85 is located in front of the first through hole 84. The closing portion 82 has a shape that protrudes upward in a wall-like manner from the rear end of the bottom wall portion 81. The pair of retaining portions 83 have a shape that protrudes upward from the front end of the bottom wall portion 81.

[0025] The housing 50 is made of synthetic resin and is a single box-shaped component that forms a rectangular prism overall. The housing 50 has a rear wall portion 51 (see Figure 2) whose thickness direction is oriented in the front-rear direction, a hood portion 52 that protrudes forward in a rectangular tube shape from the outer peripheral edge of the rear wall portion 51, a pair of symmetrical rib-shaped fitting portions 53, and a holding portion 54. The rear wall portion 51 has a fitting hole (not shown) that penetrates the rear wall portion 51 in the front-rear direction. The pair of rib-shaped fitting portions 53 are formed to extend elongated vertically along the left and right side edges of the rear wall portion 51. The plan view shape of the housing 50 when viewed from above is an L-shape, with a portion protruding rearward from the rear surface of the rear wall portion 51 and protruding inward in the width direction from its protruding end.

[0026] The retaining portion 54 has a long, narrow shape that extends in the left-right direction. Both left and right ends of the retaining portion 54 are connected to the upper ends of both rib-shaped fitting portions 53. The retaining portion 54 is positioned opposite the rear surface of the rear wall portion 51 with a gap between them. As shown in Figure 7, a long, narrow slit (not shown) is formed between the rear surface of the rear wall portion 51 and the front surface of the retaining portion 54, with openings on both the upper and lower surfaces.

[0027] The housing 50 has a cylindrical restricting cylinder portion 56 that protrudes forward from the rear wall portion 51 within the hood portion 52. The restricting cylinder portion 56 is a cylindrical portion that restricts the posture of the first cylindrical portion 72 and the second cylindrical portion 73. The rear end of the restricting cylinder portion 56 is connected to a fitting hole (not shown). The restricting cylinder portion 56 has a pair of cylindrical portions 56A that are arranged vertically. A slit is formed on a part of the outer circumference of the cylindrical portion 56A, but this is not essential. The inner circumferential surface of the cylindrical portion 56A is formed as a circumferential surface having an inner diameter corresponding to the outer diameters of the first cylindrical portion 72 and the second cylindrical portion 73.

[0028] The upper cylindrical portion 56A has an upper tip edge 56B that is located further forward (towards the front) than the tip of the first cylindrical portion 72. In other words, the upper tip edge 56B is an annular portion that extends beyond the tip of the first cylindrical portion 72 and towards the front. The lower cylindrical portion 56A has a lower tip edge 56B that is located further forward (towards the front) than the tip of the second cylindrical portion 73. In other words, the lower tip edge 56B is an annular portion that extends beyond the tip of the second cylindrical portion 73 and towards the front.

[0029] The upper tip edge 56B has a tapered upper guide surface 56C that extends inward into the first cylindrical portion 72. The guide surface 56C is the part that guides the mating shield terminal 150 (mating outer conductor 130) of the mating connector 100. More specifically, the guide surface 56C is an annular surface located on the inner circumference side of the upper tip edge 56B, in front of the upper cylindrical portion 56A. The upper guide surface 56C is formed in a tapered shape that gradually decreases in diameter towards the rear. When viewed along the central axis direction of the upper cylindrical portion 56A, it is preferable that the outer circumference edge of the upper guide surface 56C is located at the same position as or on the outer circumference side of the outer circumference surface of the first cylindrical portion 72. The lower tip edge 56B has the same configuration as the upper tip edge 56B.

[0030] The inner walls 55 of the regulating cylinder portion 56 and the hood portion 52 are spaced apart so that the hood portion 142 of the mating housing 140, which will be described later, can fit inside.

[0031] The connecting member 60 is a single component formed by bending a metal sheet material that has been punched into a predetermined shape. Therefore, all of the outer surfaces within the plate thickness range along the outer edge of the connecting member 60 are fracture surfaces.

[0032] The connecting member 60 has a base portion 61, a plurality of spring pieces 62, and an arm portion 63. The base portion 61 has a rectangular, flat horizontal plate portion 64 with its thickness direction oriented vertically, and a rectangular, flat vertical plate portion 65 extending downward from the rear end edge of the horizontal plate portion 64. In a side view of the connecting member 60, the base portion 61 is L-shaped. The plurality (three in this embodiment 1) of spring pieces 62 are cantilevered, extending diagonally upward and backward from the front end edge of the horizontal plate portion 64, and are arranged in a line in the width direction. The spring pieces 62 can elastically deform vertically, with the spring pieces 62 and the front end edge of the horizontal plate portion 64 as fulcrums.

[0033] The arm portion 63 is a flat plate oriented with its thickness direction in the front-rear direction. The arm portion 63 has a base end portion 66 and a pair of symmetrical movement restricting portions 67. The base end portion 66 is narrower than the vertical plate portion 65. The pair of movement restricting portions 67 extend downward in a cantilevered manner from the lower edge of the base end portion 66. The lower edge of the base end portion 66 and the inner edges of both left and right movement restricting portions 67 form a restricting edge portion 68 that has an arc shape when viewed from the front. The restricting edge portion 68 is interrupted at its lower end. The inner diameter of the restricting edge portion 68 is the same as the outer diameter of the first cylindrical portion 72. The widthwise distance between the lowest ends of the pair of movement restricting portions 67 is the same as the width dimension of the connecting portion 77.

[0034] Next, the assembly procedure for the connector 10 will be described. With the upper case 70 and lower case 80 separated, the first terminal module 20 and the second terminal module 30 are inserted into the box-shaped housing 71 from the rear of the upper case 70. The first mating side surrounding portion 24 is fitted into the first cylindrical portion 72 and housed there, and the second mating side surrounding portion 34 is fitted into the second cylindrical portion 73 and housed there.

[0035] In the housing 50, the connecting member 60 is attached to the holding portion 54. The base portion 61 is positioned with the horizontal plate portion 64 in contact with the upper rear end of the hood portion 52 and the vertical plate portion 65 in contact with the upper rear end of the rear wall portion 51. The arm portion 63 is inserted into the slit (not shown) of the holding portion 54 from above the housing 50. Within the slit (not shown), the base end portion 66 of the arm portion 63 is held in a state where its movement in the front-rear and left-right directions is restricted. The movement restricting portion 67 is positioned along the rear surface of the rear wall portion 51, extending downwards from the slit (not shown) and the holding portion 54.

[0036] Next, the upper case 70 is assembled to the housing 50 from the rear. At this time, the first cylindrical portion 72, the second cylindrical portion 73, and the connecting portion 77 are pressed into the fitting holes (not shown) of the rear wall portion 51 and are positioned to protrude forward from the rear wall portion 51 within the hood portion 52. By fitting the first cylindrical portion 72 and the connecting portion 77 into the restricting edge portion 68, the connecting member 60 is restricted from relative displacement in the vertical and horizontal directions with respect to the upper case 70 (outer conductor 40 and housing 50).

[0037] Next, the lower case 80 is assembled by press-fitting it into the upper case 70 from below. The first mounting-side surrounding portion 23 is accommodated in the first through-hole 84, and the second mounting-side surrounding portion 33 is accommodated in the second through-hole 85. The rib-shaped fitting portion 53 is sandwiched in the front-rear direction between the pair of retaining portions 83 and the receiving surface 75, thereby restricting the separation of the upper case 70 and the housing 50 in the front-rear direction. With this, the assembly of the connector 10 is completed.

[0038] The pair of movement restricting parts 67 of the arm part 63 come into contact with the first cylindrical part 72, thereby electrically connecting the connecting member 60 and the outer conductor 40 (upper case 70).

[0039] The assembled connector 10 is mounted on the mounting surface of the circuit board P with the connector 10 housed inside the outer ground member 11 (see Figure 2). When the connector 10 is mounted on the circuit board P, the spring piece 62 of the connecting member 60 elastically contacts the upper plate portion 12 of the ground member 11, and the outer conductor 40 and the ground member 11 are electrically connected.

[0040] (Configuration of the other connector) As shown in Figures 4 and 5, the mating connector 100 comprises a pair of mating inner conductors 110, a pair of mating dielectrics 120, a pair of mating outer conductors 130, and a mating housing 140. The mating shield terminal 150 is formed by the mating inner conductors 110, the mating dielectrics 120, and the mating outer conductors 130. The mating inner conductors 110 and the mating outer conductors 130 are made of conductive metal material. The mating dielectrics 120 and the mating housing 140 are made of synthetic resin material.

[0041] The mating inner conductor 110 is connected to the end of the shielded wire 160. The shielded wire 160 is composed of a core wire, an inner sheath, a shield section made of braided wire, and an outer sheath, arranged in order from the radial center outwards. At the end of the shielded wire 160, the outer sheath is cut off, and the core wire, inner sheath, and shield section are sequentially exposed. The core wire of the shielded wire 160 is connected to the rear end of the mating inner conductor 110 by crimping.

[0042] The opposing dielectric 120 accommodates the opposing inner conductor 110 and is positioned between the opposing inner conductor 110 and the opposing outer conductor 130. The opposing inner conductor 110 and the opposing outer conductor 130 are kept in an insulated state via the opposing dielectric 120.

[0043] The mating outer conductor 130 has a cylindrical shape that surrounds and accommodates the outer circumference of the mating dielectric 120. The mating outer conductor 130 has a plurality of spring portions 131 and a protective portion 132. The spring portions 131 are parts that can be elastically deformed to be displaced in the radial direction. The protective portion 132 is a cylindrical part that constitutes the front end of the mating outer conductor 130. In a front view of the mating outer conductor 130 viewed from the front, the protective portion 132 is circular.

[0044] The mating housing 140 houses the mating outer conductor 130 (i.e., the mating shield terminal 150) together with the mating inner conductor 110 and the mating dielectric 120. The front end of the mating shield terminal 150 is exposed within the hood portion 142. The pair of mating outer conductors 130 are spaced apart in the vertical direction. The mating housing 140 has a rear wall portion 141 (see Figure 5) and a hood portion 142 that protrudes from the rear wall portion 141 in a rectangular tube shape. The shield wire 160 is pulled out from the mating housing 140 towards the rear. An elastically deformable lock arm 143 is formed on the upper surface of the mating housing 140. The lock arm 143 can be locked into the lock portion 59 (see Figure 2) of the housing 50.

[0045] Between the pair of mating outer conductors 130 and the hood portion 142, a space (forming an eight-shape in a front view) is formed into which the restricting cylindrical portion 56 of the housing 50 of the connector 10 fits. The distance between the mating outer conductors 130 and the hood portion 142 is equal to or greater than the wall thickness of the first cylindrical portion 72 or the sum of the wall thickness of the second cylindrical portion 73 and the wall thickness of the restricting cylindrical portion 56.

[0046] When connector 10 (housing 50) and mating connector 100 (mating housing 140) are mated, the mating shield terminal 150 (mating outer conductor 130) of the mating connector 100 is guided into the guide surface 56C. The upper mating outer conductor 130 is fitted inside the first cylindrical portion 72 of the outer conductor 40, and the spring portion 131 contacts the inner surface of the first cylindrical portion 72 in an elastically deformed state. The lower mating outer conductor 130 is fitted inside the second cylindrical portion 73 of the outer conductor 40, and the spring portion 131 contacts the inner surface of the second cylindrical portion 73 in an elastically deformed state. The first inner conductor 21 and the upper mating inner conductor 110 are electrically connected, and the second inner conductor 31 and the lower mating inner conductor 110 are electrically connected.

[0047] (Characteristic configuration of the connector) As shown in Figures 6 and 7, in the housing 50 of the connector 10, a chamfered portion 91 is provided on at least one of the four corners 90 (four corners 90 in this embodiment 1) at the front end of the hood portion 52. The chamfered portion 91 is the portion that is exposed by removing the tetrahedron portion from the corner at the front end of the angular rectangular tubular shape. In the following description, we will focus on the upper right corner 90 at the front end of the hood portion 52, but the other corners 90 have a similar configuration.

[0048] The chamfered portion 91 has a chamfered surface 92. The chamfered surface 92 is a triangular (more specifically, equilateral triangle) flat surface. The chamfered surface 92 is an inclined surface that becomes outward (outward in both the vertical and horizontal directions) as it approaches the rear. The front edge 92A of the chamfered surface 92 is perpendicular to the front-to-back direction. The vertically outward edge 92B of the chamfered surface 92 is perpendicular to the vertical direction. The horizontally outward edge 92C of the chamfered surface 92 is perpendicular to the horizontal direction.

[0049] The C-surface 92 is connected to the front end surface 58 of the hood portion 52 at an obtuse angle. The front end surface 58 of the hood portion 52 is a surface perpendicular to the front-rear direction. When viewed from the left-right direction, the angle between the C-surface 92 and the front end surface 58 is obtuse. The C-surface 92 is connected to the front end surface 58 of the hood portion 52 without any step. The front edge 92A of the C-surface 92 is parallel to the front end surface 58 of the hood portion 52.

[0050] The housing 50 has recesses 93 that are recessed along at least a portion of the outer edge of the chamfered portion 91 (i.e., the C-face 92). The recesses 93 are provided along the sides of the C-face 92 other than the front side 92A (the vertically outward side 92B and the horizontally outward side 92C). The recesses 93 are recessed on the inside of the hood portion 52 (vertically inward and horizontally inward). The recesses 93 are provided adjacent to the C-face 92 on the vertically outward and horizontally outward sides.

[0051] The recess 93 has a first recess 94 and a second recess 95. The first recess 94 is the portion of the recess 93 that follows the vertically outer edge 92B of the C-surface 92. The first recess 94 extends rearward and outward in the left-right direction from the front end surface 58 of the hood portion 52. The first recess 94 is open forward from the front end surface 58 of the hood portion 52. The rear end of the first recess 94 is connected to the rear end of the second recess 95. The back surface 94A of the first recess 94 is perpendicular in the vertical direction. The back surface 94A of the first recess 94 is connected to the vertically outer edge 92B of the C-surface 92 without any step.

[0052] The second recess 95 is the portion of the recess 93 that follows the left-right outer edge 92C of the C-surface 92. The second recess 95 extends rearward and outward inward from the front end surface 58 of the hood portion 52. The second recess 95 is open forward from the front end surface 58 of the hood portion 52. The back surface 95A of the second recess 95 is perpendicular to the left-right direction. The back surface 95A of the second recess 95 is seamlessly connected to the left-right outer edge 92C of the C-surface 92.

[0053] As shown in Figure 2, the distance (shortest distance) L1 between the upper right chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52 is smaller than the distance (shortest distance) L2 between the lower right chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52, and smaller than the distance (shortest distance) L3 between the lower left chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52. The distance (shortest distance) L4 between the upper left chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52 is smaller than the distance (shortest distance) L2 between the lower right chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52, and smaller than the distance (shortest distance) L3 between the lower left chamfered portion 91 at the front end of the hood portion 52 and the inner wall 55 of the hood portion 52.

[0054] Connector 10 and the mating connector 100 properly mate when they approach each other in the front-to-back direction (the normal mating direction) with their fronts facing each other. However, as shown in Figure 8, mating (pry mating) can occur when connector 10 and the mating connector 100 approach each other at an angle to the normal mating direction. In the state shown in Figure 8, it is conceivable that the corner 90 of the hood portion 52 of connector 10 may enter the hood portion 142 of the mating connector 100. Furthermore, since the front end of the mating shield terminal 150 (mating inner conductor 110, mating dielectric 120, and mating outer conductor 130) is exposed within the hood portion 142, there is a concern that the corner 90 of the hood portion 52 of connector 10 may come into contact with it. However, since a chamfered portion 91 is provided on the corner 90 of connector 10, it is difficult for the front end of the mating shield terminal 150 to come into contact with the corner 90. Furthermore, even if the front end of the mating shield terminal 150 comes into contact with the corner portion 90, the contact is made by the chamfered portion 91 (C-surface 92) rather than the protruding portion, making it less likely for the mating shield terminal 150 to be damaged.

[0055] As described above, the connector 10 of this embodiment 1 includes a housing 50 having a rectangular tubular hood portion 52. A chamfered portion 91 is provided on at least one of the four corners 90 (four corners 90 in this embodiment 1) at the front end of the hood portion 52. With this configuration, when prying mating with the mating connector 100 (mating in a position where it approaches at an oblique angle to the normal mating direction), the chamfered portion 91 makes it difficult for the corner 90 at the front end of the hood portion 52 to come into contact with the mating terminal (matting shield terminal 150). This makes it easier to prevent prying of the mating terminal (matting shield terminal 150) as it approaches so that the corner 90 at the front end of the hood portion 52 comes into contact with the mating terminal (matting shield terminal 150).

[0056] In the connector 10 of this embodiment 1, the chamfered portion 91 has a chamfered surface 92. With this configuration, even if the chamfered surface 92 comes into contact with the mating terminal (mating shield terminal 150), the chamfered surface 92 is more likely to make surface contact with the mating terminal (mating shield terminal 150), making it less likely to damage the mating terminal (mating shield terminal 150).

[0057] In the connector 10 of this embodiment 1, the C-surface 92 is connected to the front end surface 58 of the hood portion 52 at an obtuse angle. With this configuration, there are no protrusions, steps, etc. on the side of the housing 50 into which the mating terminal (mating shield terminal 150) is inserted, making it less likely for the mating terminal (mating shield terminal 150) to be damaged.

[0058] In the connector 10 of this embodiment 1, the housing 50 has a recess 93 that is recessed along at least a portion of the outer edge of the chamfered portion 91 (the outer edge 92B in the vertical direction and the outer edge 92C in the horizontal direction of the C-surface 92). With this configuration, the outer edge of the chamfered portion 91 is recessed inward, making it less likely for the housing 50 to damage the mating terminal (the mating shield terminal 150).

[0059] In the connector 10 of this embodiment 1, chamfered portions 91 are provided on each of the four corners 90 of the hood portion 52. With this configuration, the chamfered portions 91 are provided on each of the four corners 90, making it even less likely for the front corners 90 of the hood portion 52 to come into contact with the mating terminal (matting shield terminal 150). This makes it even easier to prevent the mating terminal (matting shield terminal 150) from being twisted.

[0060] In the connector 10 of this embodiment 1, there is a dielectric (first dielectric 22) that houses an inner conductor (first inner conductor 21), and an outer conductor 40 (first cylindrical portion 72) that houses the dielectric (first dielectric 22). In the connector 10, there is a dielectric (second dielectric 32) that houses an inner conductor (second inner conductor 31), and an outer conductor 40 (second cylindrical portion 73) that houses the dielectric (second dielectric 32). The housing 50 houses the outer conductor 40 (first cylindrical portion 72, second cylindrical portion 73). With this configuration, the shielding performance for the inner conductors (first inner conductor 21, second inner conductor 31) can be enhanced by the outer conductor 40.

[0061] The connector device C of this embodiment 1 comprises a connector 10 and a mating connector 100 that mates with the connector 10. The mating connector 100 has a mating shield terminal 150 housed in a mating housing 140. The mating shield terminal 150 has a mating inner conductor 110, a mating dielectric 120 that houses the mating inner conductor 110, and a mating outer conductor 130 that houses the mating dielectric 120. The mating outer conductor 130 is exposed inside the mating housing 140. With this configuration, in a configuration where the mating outer conductor 130 is exposed inside the mating housing 140, the configuration in which chamfered portions 91 are provided on the corners 90 has the advantage of making it easier to prevent twisting of the mating terminal (matting shield terminal 150).

[0062] [Other embodiments of this disclosure] Embodiment 1 disclosed herein should be considered in all respects to be illustrative and not restrictive. In the above embodiment 1, chamfered portions 91 were provided at each of the four corners 90 of the hood portion 52, but it is sufficient if they are provided at at least one of the four corners 90. In the above embodiment 1, the chamfered portion 91 had a C-surface 92, but a surface of another shape may be provided instead of the C-surface 92. For example, the chamfered portion 91 may be provided with a curved surface (a curved surface that is convex outward, a curved surface that is concave inward). In the above embodiment 1, the C-surface 92 was triangular, but it may be of other shapes (other polygons, circles, rings, etc.). In the above embodiment 1, the C-surface 92 was seamlessly connected to the front end surface 58 of the hood portion 52, but a recess that is inward may be provided. Such a recess may be connected to a recess 93 and may form an annular shape along the outer edge of the chamfered portion 91 together with the recess 93. In the above embodiment 1, the recess 93 may not be provided, and the chamfered portion 91 may be connected to the outer surface of the hood portion 52 without any step difference.
