[0016] Embodiment 1 A connector 1 according to a first embodiment of the present invention and a connector unit A including the same will be described below with reference to Figures 1 to 13. For ease of understanding, mutually orthogonal XYZ coordinates are set and referenced as appropriate. The +Y direction of the XYZ coordinates is the same direction as the mating direction D1 in which the mating connector 100 moves to mate with the connector 1, as shown in Figures 1 and 2. The X-axis direction is the same direction as the width direction of the connector 1. The Z-axis direction is a direction perpendicular to both the X-axis direction and the Y-axis direction.

[0017] The connector unit A is, for example, an in-vehicle connector unit used as an automobile part. The connector unit A includes a connector 1 and a mating connector 100 to which the connector 1 is mated. The connector unit A is used to connect a cable C drawn out from an electronic component mounted on the automobile to a board 200 that is part of the component mounted on the automobile. In the first embodiment, the cable C is a coaxial cable having an inner conductor and an outer conductor. However, the present invention is not limited to this, and the cable C may be something other than a coaxial cable.

[0018] As shown in FIGS. 2 and 3, the mating connector 100 includes a housing 110 and a mating terminal 120.

[0019] The housing 110 is made of an insulating material such as resin, and is formed into a shape that allows it to fit into the fitting hole 41 of the housing 40 of the connector 1. The housing 110 is formed with a locking portion 110a, a support arm 110b, an unlocking operation portion 110c, and a through hole 110d.

[0020] The locking portion 110a locks the mating connector 100 to the connector 1 by being locked into the locked hole 42 of the housing 40 of the connector 1. The locking portion 110a is provided to protrude from the support arm 110b in the +Z direction.

[0021] Support arm 110b extends toward the rear end (-Y direction) from the tip end portion closer to the +Y side of housing 110. Support arm 110b is provided so as to bend as mating of mating connector 100 and connector 1 progresses.

[0022] The unlocking operation portion 110c is provided on the support arm 110b. The unlocking operation portion 110c is used by an operator to remove the mating connector 100 from the connector 1. The unlocking operation portion 110c is provided so as to be movable in the Z-axis direction as the support arm 110b flexes. By moving the unlocking operation portion 110c in the -Z direction, the locking portion 110a and the locked hole 42 are released from engagement.

[0023] The through-hole 110d is a hole into which the mating terminal 120 is inserted. The through-hole 110d is formed to penetrate in the Y-axis direction.

[0024] As shown in FIG. 3, the mating terminal 120 includes a center terminal 120a, a dielectric 120b, a crimp tube 120c, and a ground terminal 120d.

[0025] The center terminal 120a is electrically connected to the inner conductor of the cable C and transmits high frequency signals.

[0026] The dielectric 120b is used to match the characteristic impedance of the transmission line and to efficiently propagate the high frequency signal at the center terminal 120a. The center terminal 120a is fitted into the dielectric 120b.

[0027] The crimp tube 120c sandwiches the outer conductor of the cable C between the crimp tube 120c and the ground terminal 120d, thereby electrically connecting the outer conductor of the cable C and the ground terminal 120d.

[0028] The ground terminal 120d is electrically connected to the outer conductor of the cable C and is used to efficiently propagate high-frequency signals at the center terminal 120a. The ground terminal 120d prevents high-frequency signals from leaking outside the cable C and the mating terminal 120, and also blocks radio waves from entering from outside. The ground terminal 120d is provided with a crimping portion 120d-1.

[0029] By crimping the crimping portion 120d-1 to the cable C, the ground terminal 120d is fixed to the cable C while being electrically connected to the outer conductor of the cable C.

[0030] As shown in Fig. 2, the connector 1 is an SMT (Surface Mount Technology) connector that is attached to a substrate 200 and into which a mating connector 100 is mated. As shown in Figs. 4 to 6, the connector 1 includes an inner conductor 10, a dielectric 20, an outer conductor 30, a housing 40, and a hold-down portion 50.

[0031] The inner conductor 10 is made of, for example, a conductive material. Examples of conductive materials that can be used include copper and copper alloys. The inner conductor 10 is formed by bending a rod-shaped member into an L-shape. A center terminal 120a of a mating terminal 120 is connected to the inner conductor 10. As a result, the inner conductor 10 is electrically connected to the inner conductor of the cable C via the center terminal 120a, and transmits high-frequency signals from the inner conductor of the cable C and to the inner conductor of the cable C.

[0032] As shown in FIG. 4, the dielectric 20 is a member that covers a part of the internal conductor 10. In the present embodiment 1, the dielectric 20 is formed by insert molding the internal conductor 10. The dielectric 20 is made of an insulating material. The dielectric 20 is used to match the characteristic impedance of the cable C and efficiently propagate high-frequency signals in the internal conductor 10. The dielectric 20 has a main body portion 21 and an extension portion 22.

[0033] The main body 21 accommodates the internal conductor 10. The main body 21 is formed in a substantially cylindrical shape.

[0034] The extension portion 22 extends from the end portion of the main body portion 21 closer to the +Y direction and protrudes in the −Z direction.

[0035] The outer conductor 30 is a member that covers a part of the dielectric 20. The outer conductor 30 is formed by bending a plate made of a conductive material. Examples of the conductive plate material include copper and copper alloys. The ground terminal 120d of the mating terminal 120 is connected to the outer conductor 30. As a result, the outer conductor 30 is electrically connected to the outer conductor of the cable C via the ground terminal 120d. The outer conductor 30 prevents leakage of high-frequency signals from the inner conductor 10 to the outside of the outer conductor 30 and blocks radio waves from the outside. As shown in FIG. 7, the outer conductor 30 has a main body portion 31, a lid portion 32, a pair of locking portions 33R and 33L, a pair of extension portions 34R and 34L (see FIG. 6), and a hinge portion 35.

[0036] The main body 31 is for accommodating the dielectric 20 together with the internal conductor 10. In the present embodiment 1, the main body 31 is formed in a shape that can receive the center terminal 120a and the dielectric 120b of the mating terminal 120. Specifically, the main body 31 has openings that open in both the -Y direction and the +Y direction, and is formed in a substantially cylindrical shape with the Y-axis direction as the cylindrical axis direction.

[0037] The lid portion 32 is intended to close an opening of the main body portion 31 that opens in the +Y direction in order to cover a portion of the dielectric 20 housed in the main body portion 31. The lid portion 32 is connected to the main body portion 31 by a hinge portion 35. By being connected to the hinge portion 35, the lid portion 32 is provided so as to be bendable relative to the main body portion 31 from a position that does not close the opening of the main body portion 31 to a position that closes it, as shown by arrow Y1 in Fig. 8(A). The lid portion 32 is formed with a pair of bent portions 32a.

[0038] 8B. The bent portion 32a is provided so as to be bendable along the arrow Y2 in Fig. 8B. The bent portion 32a holds the lid portion 32 on the dielectric 20 by being bent along the arrow Y2.

[0039] As shown in FIGS. 4 and 10 , the locking portions 33R and 33L are used to fix the outer conductor 30 or the terminal B to the housing 40 by engaging with the housing 40. In the first embodiment, the locking portions 33R and 33L are formed on both the +X side and the −X side of the main body portion 31 so as to sandwich the main body portion 31. The locking portions 33R and 33L are formed to extend from the lid portion 32, which is a part of the outer conductor 30. Specifically, as shown in FIGS. 4(A) and 6 , the locking portions 33R and 33L are formed to extend from the lid portion 32 along the Y-axis direction (fitting direction D1) when the lid portion 32 is bent relative to the main body portion 31. As shown in FIGS. 6 and 9 , the locking portions 33R and 33L are formed with contact portions 33a that come into contact with the main body portion 31. As shown in FIG. 10, the locking portions 33R and 33L are formed with locking projections 33b.

[0040] The contact portion 33a is provided so as to come into contact with the main body 31 of the outer conductor 30 by pressing forces P1 and P2 from the mating connector 100 when the connector 1 is mated with the mating connector 100. When the connector 1 is not mated with the mating connector 100, the contact portion 33a is provided slightly spaced apart from the main body 31 of the outer conductor 30. In the first embodiment, the contact portion 33a is formed at the extended tip (the tip closer to the -Y direction) of the locking portions 33R and 33L. Specifically, the extended tip of the pair of locking portions 33R and 33L is curved inward (closer to the main body 31). The contact portion 33a is formed at the tip of the locking portions 33R and 33L that is curved inward. Furthermore, the contact portion 33a of the locking portion 33R is formed to protrude from the locking portion 33R in the −X direction, and the contact portion 33a of the locking portion 33L is formed to protrude from the locking portion 33L in the +X direction.

[0041] The extensions 34R, 34L are formed to extend further from the tips of the locking portions 33R, 33L. Specifically, the extensions 34R, 34L are formed to be curved outward (away from the main body 31) from the extended tips of the locking portions 33R, 33L, and are further curved inward (toward the main body 31) from the extended tips. The curved shapes of the extensions 34R, 34L result in a generally arch-like shape that convex outward. The extensions 34R, 34L are formed with guide portions 34a that, upon contact with the mating connector 100, move the contact portions 33a inward (toward the main body 31) and assist the contact of the contact portions 33a with the main body 31. The guide portions 34a are provided at the apex of the arch shape constituting the extensions 34R, 34L. Furthermore, guide portion 34a of extension portion 34R is formed to protrude in the +X direction, which is the direction opposite to the protruding direction (-X direction) of contact portion 33a of locking portion 33R. Similarly, guide portion 34a of extension portion 34L is formed to protrude in the -X direction, which is the direction opposite to the protruding direction (+X direction) of contact portion 33a of locking portion 33L.

[0042] 6, the tip of extension portion 34R extending from the tip of locking portion 33R closer to the -Y direction is formed as a free end when connector 1 is not mated with mating connector 100. Similarly, the tip of extension portion 34L extending from the tip of locking portion 33L closer to the -Y direction is formed as a free end when connector 1 is not mated with mating connector 100.

[0043] The inner conductor 10, the dielectric 20, and the outer conductor 30 formed as above are assembled together to form a terminal B to which a mating terminal 120 is connected, as shown in FIG.

[0044] As shown in Fig. 2, the housing 40 is a generally box-shaped member that opens in the -Y direction and has a mating hole 41 formed therein, into which the mating connector 100 is fitted. The housing 40 is made of an insulating material such as resin. As shown in Fig. 4, a portion of the outer conductor 30 is press-fitted into the housing 40 together with a portion of the inner conductor 10 and a portion of the dielectric 20. The housing 40 is formed with a locking hole 42, protective side walls 43R and 43L, and a press-fit hole 44.

[0045] The locking hole 42 is formed penetrating in the Z-axis direction from the outside of the housing 40 to the inside of the fitting hole 41. In the first embodiment, the locking hole 42 is a hole penetrating in the Z-axis direction. However, this is not limited to this. The locking hole 42 may also be a blind hole.

[0046] The protective side walls 43R and 43L are formed to protrude from the rear end surface of the housing 40 closer to the +Y side. The protective side walls 43R and 43L are formed to protect the exposed portion of the outer conductor 30 or the terminal B attached to the housing 40.

[0047] The press-fit hole 44 is a hole formed for press-fitting the outer conductor 30 into the housing 40 along the press-fit direction D2. As shown in FIG. 10 , the press-fit hole 44 is formed penetrating from the inside of the fitting hole 41 to the outside of the housing 40 in the Y-axis direction. The outer conductor 30 or the terminal B is press-fitted into the press-fit hole 44 along the press-fit direction D2. The press-fit hole 44 has grooves 44a formed along the Y-axis direction (press-fit direction D2) in which the locking portions 33R, 33L of the outer conductor 30 are disposed. The outer conductor 30 press-fitted into the press-fit hole 44 is fixed to the housing 40 by the locking protrusions 33b formed on the locking portions 33R, 33L biting into the inner surfaces of the grooves 44a. Consequently, the terminal B including the outer conductor 30 is fixed to the housing 40 while being prevented from slipping out of the press-fit hole 44.

[0048] 2, hold-down portion 50 is a member that is fixed to housing 40 and also fixed to the surface of substrate 200. Hold-down portion 50 is made of, for example, a relatively rigid metal. This hold-down portion 50 firmly fixes housing 40 and substrate 200 together.

[0049] A method of fitting the connector 1 of the connector unit A configured as described above to the mating connector 100 will be described with reference to the drawings.

[0050] 2 and 11, first, an operator inserts the mating connector 100 into the mating hole 41 of the connector 1 along the mating direction D1. As the mating connector 100 is inserted into the mating hole 41 of the connector 1, as shown in Fig. 12, the tip (the tip closer to the +Y direction) of the housing 110 of the mating connector 100 eventually comes into contact with the outer conductor 30 of the connector 1. Then, the extension portions 34R, 34L of the outer conductor 30 are guided by the opening of the through hole 110d of the housing 110 or the inner circumferential surface near the opening, as shown by arrow Y3, and bend toward the main body portion 31 of the outer conductor 30.

[0051] Furthermore, as the mating connector 100 is inserted into the mating hole 41 of the connector 1, the guide portions 34a of the extension portions 34R, 34L come into contact with the inner circumferential surface of the through hole 110d of the housing 110, as shown in FIG. 9. The contact of the guide portions 34a with the inner circumferential surface of the through hole 110d generates pressing forces P1, P2 from the housing 110 of the mating connector 100, and the extension portions 34R, 34L are pressed toward the main body portion 31 of the outer conductor 30. As the extension portions 34R, 34L are pressed toward the main body portion 31, the distal ends (proximal ends closer to the -Y direction) of the locking portions 33R, 33L relative to the locking protrusions 33b (see FIG. 10) also bend toward the main body portion 31. As a result, the contact portions 33a of the locking portions 33R, 33L come into contact with the main body portion 31 of the outer conductor 30. The locking portions 33R and 33L are connected to the main body portion 31 via the contact portion 33a, and are capable of transmitting high frequency signals.

[0052] With the above, the mating of the connector 1 of the connector unit A and the mating connector 100 is completed.

[0053] 6 and 9, in the connector 1 according to the first embodiment, the locking portions 33R, 33L have contact portions 33a, which contact portions 33a come into contact with the main body 31. This allows the connector 1 to suppress deterioration of high-frequency characteristics caused by the locking portions 33R, 33L.

[0054] For example, in the connector 1A according to the comparative example shown in FIG. 13, the locking portions 33R and 33L are not in contact with the main body 31, and the ends of the locking portions 33R and 33L are configured as free ends. In this case, in the connector 1A, high-frequency signals are reflected by the extended ends of the locking portions 33R and 33L. As a result, there is a risk that the high-frequency characteristics of the connector 1A will deteriorate.

[0055] 6 and 9, in the connector 1 according to the first embodiment, the contact portions 33a of the locking portions 33R, 33L contact the main body 31. Therefore, the high-frequency signal propagated from the cover 32 to the locking portions 33R, 33L propagates from the locking portions 33R, 33L to the main body 31 via the contact portions 33a. This prevents the extended ends of the locking portions 33R, 33L from functioning as antennas, and can prevent deterioration of high-frequency characteristics caused by reflection of the high-frequency signal at the locking portions 33R, 33L.

[0056] Furthermore, in the connector 1 according to the first embodiment, the contact portion 33a is arranged to come into contact with the main body 31 of the outer conductor 30 by pressing forces P1 and P2 from the mating connector 100 when the connector 1 and the mating connector 100 are mated. Therefore, in the first embodiment, the contact portion 33a can be brought into contact with the main body 31. This allows the connector 1 to further enhance the effect of suppressing deterioration of high-frequency characteristics caused by reflection of high-frequency signals at the locking portions 33R and 33L.

[0057] Furthermore, in the connector 1 according to the first embodiment, the main body 31 of the outer conductor 30 is formed in a cylindrical shape. The contact portion 33a is in contact with the outer peripheral surface of the main body 31, which is also formed in a cylindrical shape. This allows the connector 1 to further effectively suppress deterioration of high-frequency characteristics caused by reflection of high-frequency signals at the locking portions 33R, 33L.

[0058] Furthermore, in the connector 1 according to the first embodiment, the contact portion 33a is formed at the extended tip of the locking portions 33R, 33L. Therefore, the contact portion 33a is located at a position where it can easily come into contact with the main body portion 31 of the outer conductor 30 due to the pressing forces P1, P2 from the mating connector 100 that occur when the connector 1 is mated with the mating connector 100. This makes it easier for the contact portion 33a to come into contact with the main body portion 31 in the connector 1. Furthermore, it is possible to suppress reflection of high-frequency signals at the locking portions 33R, 33L. This allows the connector 1 to further effectively suppress deterioration of high-frequency characteristics.

[0059] Furthermore, in the connector 1 according to the first embodiment, the outer conductor 30 has extension portions 34R, 34L extending from the extended tips of the locking portions 33R, 33L. The extension portions 34R, 34L are formed with guide portions 34a. Therefore, by contacting the mating connector 100, the guide portions 34a can move the contact portions 33a toward the main body portion 31 and assist the contact of the contact portions 33a with the main body portion 31. Therefore, the connector 1 can more easily achieve contact of the contact portions 33a with the main body portion 31. This allows the connector 1 to more effectively suppress deterioration of high-frequency characteristics caused by the locking portions 33R, 33L.

[0060] In the first embodiment, the tips of the extension portions 34R and 34L are configured as free ends. In this case, there is a concern that high-frequency signals may be reflected by the extended tips of the locking portions 33R and 33L in the connector 1A. However, by shortening the length of the extension portions 34R and 34L in the Y-axis direction relative to the length of the locking portions 33R and 33L in the Y-axis direction, the frequency at which the high-frequency characteristics deteriorate can be shifted to the higher frequency side. Therefore, even if the outer conductor 30 has the extension portions 34R and 34L in the first embodiment, it is possible to sufficiently reduce the impact of deterioration of the high-frequency characteristics.

[0061] Furthermore, in the connector 1 according to the first embodiment, the guide portion 34a is formed in a shape that protrudes in a direction opposite to the protruding direction of the contact portion 33a. Therefore, by contacting the mating connector 100, the guide portion 34a moves the contact portion 33a toward the main body portion 31, thereby efficiently assisting the contact portion 33a to contact the main body portion 31. Therefore, in the connector 1, it is easier to bring the contact portion 33a into contact with the main body portion 31. This allows the connector 1 to further effectively suppress deterioration of high-frequency characteristics caused by the locking portions 33R, 33L.

[0062] Embodiment 2 In the connector 1 according to the first embodiment, as shown in FIG. 9 , the contact portion 33a of the outer conductor 30 is configured to contact the main body 31 when the connector 1 is mated with the mating connector 100 due to pressing forces P1 and P2 from the mating connector 100. That is, the contact portion 33a is not in contact with the main body 31 before the connector 1 is mated with the mating connector 100. However, this is not limited to this. The contact portion 33a does not have to contact the main body 31 due to pressing forces P1 and P2 from the mating connector 100. Hereinafter, a connector 2 according to a second embodiment, which has a different structure for the contact portion 33a, will be described, focusing on differences from the first embodiment, with reference to FIG. 14 . Other than the differences described above, the connector 2 is considered to be the same or equivalent to the first embodiment. For ease of understanding, XYZ coordinates are set and referenced as appropriate.

[0063] As shown in FIG. 14, similar to the connector 1, the connector 2 includes an inner conductor 10, a dielectric 20, an outer conductor 30-2, a housing 40, and a hold-down portion 50.

[0064] The outer conductor 30-2 has a main body portion 31, a lid portion 32, a pair of locking portions 33R, 33L, a pair of extension portions 34R, 34L, and a hinge portion 35. The contact portion 33a of the outer conductor 30-2 is provided so as to come into contact with the main body portion 31 by bending the lid portion 32 relative to the main body portion 31. In other words, the contact portion 33a is provided so as to come into contact with the main body portion 31 even when the connector 1 and the mating connector 100 are not mated.

[0065] In addition, in embodiment 2, the contact portion 33a is arranged so as to come into contact even when the connector 2 and the mating connector 100 are not mated, and therefore, unlike the connector 1, the extension portions 34R and 34L do not have a guide portion 34a.

[0066] As described above, in the connector 2 according to the second embodiment, as in the first embodiment, the locking portions 33R and 33L have contact portions 33a, and the contact portions 33a come into contact with the main body portion 31. Therefore, a high-frequency signal propagated from the cover portion 32 to the locking portions 33R and 33L propagates from the locking portions 33R and 33L to the main body portion 31 via the contact portions 33a. This prevents the extended ends of the locking portions 33R and 33L from functioning as antennas, and can prevent deterioration of high-frequency characteristics caused by reflection of high-frequency signals at the locking portions 33R and 33L.

[0067] In the connector 2 according to the second embodiment, the contact portions 33a of the locking portions 33R, 33L of the outer conductor 30-2 are arranged to come into contact with the main body 31 when the cover 32 is bent. Therefore, the connector 2 can bring the contact portions 33a of the outer conductor 30-2 into contact with the main body 31, regardless of whether the connector 2 and the mating connector 100 are mated or not.

[0068] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments.

[0069] For example, in the above-described embodiment, the outer conductors 30, 30-2 have the extension portions 34R, 34L as shown in Figs. 6 and 14. However, this is not limiting. The outer conductors 30, 30-2 do not necessarily have to have the extension portions 34R, 34L. However, when the lid portion 32 is bent relative to the main body portion 31, there is a risk that the tips of the locking portions 33R, 33L may damage the main body portion 31. Therefore, it is preferable that the outer conductors 30, 30-2 have the extension portions 34R, 34L.

[0070] In the above-described embodiment, the outer conductor 30, 30-2 has a pair of locking portions 33R, 33L. However, this is not limited to this. The outer conductor 30, 30-2 may have only one locking portion 33R, 33L, or may have three locking portions 33R, 33L.

[0071] Similarly, the outer conductor 30, 30-2 has a pair of extension portions 34R, 34L. However, this is not limited to this. The outer conductor 30, 30-2 may have only one extension portion 34R, 34L, or may have three extension portions 34R, 34L.

[0072] In the above embodiment, the locking portions 33R and 33L extend from the lid portion 32. However, this is not limited to this. The locking portions 33R and 33L may extend from a part of the outer conductor 30 other than the lid portion 32. Furthermore, the outer conductor 30 does not necessarily have to have the lid portion 32.

[0073] In the above embodiment, the locking portions 33R and 33L extend from the lid portion 32, which is a part of the outer conductor 30. The extension portions 34R and 34L extend from the tips of the locking portions 33R and 33L. The locking portions 33R and 33L are formed with contact portions 33a, and the extension portions 34R and 34L are formed with guide portions 34a. Thus, the contact portions 33a and the guide portions 34a are formed in this order along the press-fitting direction D2 (-Y direction). However, this is not limiting. The guide portions 34a and the contact portions 33a may be formed in this order along the press-fitting direction D2 (-Y direction), which is the opposite of the order of the contact portions 33a and the guide portions 34a in the above embodiment.

[0074] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and are not intended to limit the scope of the present invention. [Explanation of symbols]
