[0011] (First embodiment) Hereinafter, a female connector (also simply referred to as a "connector") 10 according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the female connector 10 of this embodiment is connected to the tip of a coaxial cable 100 and is mated with a male connector 200, which is a mating connector. The male connector 200 is connected to the tip of a coaxial cable 300 and is mated with the female connector 10. This mating electrically connects the coaxial cable 100 of the female connector 10 and the coaxial cable 300 of the male connector 200. In addition, the female connector 10 and the male connector 200 have a shielding function for suppressing electromagnetic noise that enters from the outside through the coaxial cables 100 and 300. The female connector 10 and the male connector 200 function as high-frequency connectors capable of transmitting high-frequency signals, for example.

[0012] First, a description will be given of male connector 200, which is a mating connector, and coaxial cable 300, which transmits electrical signals. Male connector 200 includes male outer housing 201, male outer terminal 202, male inner housing 203, and male inner terminal 204.

[0013] The resin male outer housing 201 constitutes the exterior of the male connector 200, and has a hood portion 201a and a lock hole 201b. The hood portion 201a is a portion of the male outer housing 201 that has a slightly larger diameter, and a rectangular lock hole 201b is formed in the upper surface of the hood portion 201a. The hood portion 201a and the lock hole 201b are portions that are responsible for fitting with the female connector 10, as described below.

[0014] On the inner surface of the male outer housing 201, a male outer terminal 202, a male inner housing 203, and a male inner terminal 204 are arranged in this order from the outside to the center in a radial direction perpendicular to the longitudinal direction of the male connector 200. As described later, the metallic male outer terminal 202 serves to ground electromagnetic noise entering from the outside via the coaxial cable 300. The resin male inner housing 203 serves as an insulating member that electrically insulates the metallic male outer terminal 202 and the metallic male inner terminal 204.

[0015] The metallic male inner terminal 204 is disposed at the radial center of the male connector 200 and is attached to a core wire 301 which is the inner conductor of the coaxial cable 300. The male inner terminal 204 transmits an electrical signal from the core wire 301 to the female connector 10, as described below.

[0016] As shown in Figures 1 to 3, the female connector 10 of the first embodiment comprises a female outer housing 11, a female outer terminal (also simply referred to as an "outer terminal") 40, a female inner housing (also simply referred to as an "insulating member") 30, and a female inner terminal (also simply referred to as an "inner terminal") 20.

[0017] As shown in FIG. 1, a resin female outer housing 11 constitutes the exterior of the female connector 10 and has a lock arm 11a and a lock protrusion 11b for fitting with the male connector 200. The lock arm 11a has a cantilever shape, and the lock protrusion 11b is formed on the lock arm 11a. The user lowers the lock arm 11a while pressing the end of the lock arm 11a, and inserts the female connector 10 into the hood portion 201a of the male connector 200. After insertion, when the user returns the lock arm 11a to its original position, the lock protrusion 11b engages with the lock hole 201b, and the female connector 10 and the male connector 200 fit together.

[0018] In addition, the spacer 12 is attached to the underside of the female outer housing 11, and during the assembly process, the spacer 12 can be engaged from the underside of the female outer housing 11 to engage the female outer terminals 40 and the like inside the female outer housing 11.

[0019] FIG. 2 shows a cross section of the female connector 10 with the female outer housing 11 removed, and the assembly in this state may be called a "female connector" or a "connector". The female connector 10 is a connector that is attached to the end of a coaxial cable 100. The coaxial cable 100 is a cable having a core wire 101 that is an inner conductor, an insulator 102 that covers the core wire 101, a braid 103 that is an outer conductor that covers the insulator 102, and a sheath 104 that is the outermost layer. The braid 103 is connected to, for example, an earth wire (not shown) and functions as a ground. Note that the coaxial cable 300 in FIG. 1 also has a core wire 301, an insulator 302, a braid 303, and a sheath 304, similar to the coaxial cable 100.

[0020] The female connector 10 has the configuration shown in Fig. 2 in addition to the female outer housing 11 shown only in Fig. 1. That is, the female connector 10 has a female inner terminal 20 attached to a core wire 101 of a coaxial cable 100, a female inner housing 30 that covers the female inner terminal 20, and a female outer terminal 40 that covers the female inner housing 30. On the inner surface of the female outer housing 11, the female outer terminal 40, the female inner housing 30, and the female inner terminal 20 are arranged in this order from the outside to the center in the radial direction of the female connector 10.

[0021] The metallic female inner terminal 20 is disposed at the radial center of the female connector 10, and is connected to the male inner terminal 204 of the male connector 200 when the female connector 10 and the male connector 200 are mated. As a result, an electrical signal from the core wire 301 of the coaxial cable 300 is transmitted to the core wire 101 of the coaxial cable 100 through the male inner terminal 204 and the female inner terminal 20.

[0022] The resin-made hollow cylindrical female inner housing 30 is arranged to cover the female inner terminal 20 in the radial direction, and serves as an insulating member that electrically insulates the female inner terminal 20 from the outer female outer terminal 40. The metallic female outer terminal 40 is arranged to cover the entire circumference of the female inner housing 30, and is crimped to the braid 103 of the coaxial cable 100 and electrically connected to the braid 103. The female outer terminal 40 has a contact spring 41 at its tip. When the female connector 10 and the male connector 200 are mated, the contact spring 41 comes into contact with the inner surface of the male outer terminal 202 and is electrically connected to the male outer terminal 202. As a result, the braid 303 of the coaxial cable 300, the male outer terminal 202, the female outer terminal 40, and the braid 103 of the coaxial cable 100 are electrically connected to each other and function as a ground, and electromagnetic wave noise entering from the outside through the coaxial cable 300 can be blocked.

[0023] Next, the female outer terminal 40 will be described in detail. The female outer terminal 40 is formed into a substantially cylindrical shape by, for example, performing a punching process, a bending process, or the like on a metal plate. The female outer terminal 40 includes a cylindrical tubular portion 45, a braided crimping piece (also simply referred to as a "crimping piece") 43, and a sheath crimping piece 42. The tubular portion 45 includes an inner housing accommodating chamber 48 that is an accommodating chamber capable of accommodating the female inner housing 30 therein, and accommodates the female inner housing 30. The braided crimping piece 43 is a metal piece that is crimped to the braid 103 of the coaxial cable 100, and the crimping method will be described later. The sheath crimping piece 42 is a metal piece formed adjacent to the braided crimping piece 43 across a notch portion 44 in the longitudinal direction of the female outer terminal 40. The crimping method will be described later.

[0024] Moreover, the sheath 104 of the coaxial cable 100 covers the braid 103 except for the tip portion 105. A braid fold (also simply referred to as a "folded portion") 103a is formed in the coaxial cable 100 by folding back the tip portion 105 of the braid 103 onto the insulator 102, which is a part of the tip portion 105 of the braid 103. Note that the braid fold 103a is folded back onto a sleeve 106 attached to the coaxial cable 100, as will be described in the assembly method described later (see Figs. 4C to 4G).

[0025] Next, the female inner housing 30 will be described in detail. In this embodiment, the female inner housing 30 is provided with a press-fit rib 33 formed of a protrusion that contacts the inner wall of the inner housing accommodation chamber 48 when the female inner housing 30 is accommodated in the inner housing accommodation chamber 48 of the female outer terminal 40. The press-fit rib 33 extends along the longitudinal direction of the female inner housing 30 on the outer periphery of the female inner housing 30, and a plurality of ribs protruding from the outer periphery are provided at intervals from each other.

[0026] As a result, when the female inner housing 30 covering the female inner terminal 20 is accommodated in the inner housing accommodation chamber 48 of the female outer terminal 40, the press-fit rib 33 comes into contact with the inner wall of the inner housing accommodation chamber 48. This makes it possible to suppress tilting of the female inner terminal 20 and the core wire 101 in the female outer terminal 40. This makes it possible to stabilize the impedance between the female inner terminal 20 and the female outer terminal 40. The stabilization of the impedance makes it possible to improve the transmission performance of the female connector 10.

[0027] The press-fit rib 33 includes a plurality of ribs (press-fit ribs) provided on the outer periphery of the female inner housing 30 at a distance from each other.

[0028] As a result, the multiple ribs constituting the press-fit rib 33 are provided on the outer periphery of the female inner housing 30, thereby reliably suppressing tilting of the female inner terminal 20 and the core wire 101. In this example, four ribs constituting the press-fit rib 33 are provided at equal intervals on the outer periphery of the female inner housing 30. As a result, the female inner terminal 20 can be reliably held in the inner housing accommodating chamber 48, thereby further reliably suppressing tilting of the female inner terminal 20 and the core wire 101.

[0029] The inner housing accommodating chamber 48 is arranged along the central axis (the central axis in the radial direction) of the female outer terminal 40, and the press-in rib 33 is configured so that the female inner housing 30 is held within the inner housing accommodating chamber 48 along this central axis.

[0030] As a result, the press-fit rib 33 holds the female inner housing 30 along the central axis of the female outer terminal 40, making it possible to stabilize impedance without being affected by vibrations, etc., when mounted on a vehicle.

[0031] 2 and 3, the female inner terminal 20 has a fitting connection portion 21 that can be fitted with a male inner terminal 204, which is a mating terminal, and an electric wire connection portion 22 that is crimped to an insulator 102 of a coaxial cable 100. The female inner housing 30 has a first portion 31 that covers the fitting connection portion 21 and a second portion 32 that covers the electric wire connection portion 22. In this configuration, the press-fit rib 33 is provided on the outer periphery of the second portion 32.

[0032] As a result, the female inner housing 30 has a press-fit rib 33 on the outer periphery of the second part 32 that covers the wire connection portion 22 of the female inner terminal 20, thereby preventing deformation of the wire connection portion 22, which is easily deformed, and making the impedance more stable.

[0033] Furthermore, the female inner housing 30 has at least a pair of flexible pieces 34 that sandwich the insulator 102 of the coaxial cable 100. The flexible pieces 34 are provided at the rear end of the female inner housing 30, behind a locking protrusion for locking the female inner housing 30 to the inner wall of the outer terminal 40. In this example, the female inner housing 30 has two pairs of flexible pieces 34. The flexible pieces 34 have a shape obtained by dividing an annular member into four equal parts in the circumferential direction. The flexible pieces 34 sandwich the insulator 102, thereby correcting the core wire 101 so that the female inner terminal 20 is disposed at the center of the female inner housing 30. Therefore, the insulator layer and the air layer of the female inner housing 30 and the coaxial cable 100 become uniform all around, so that the dielectric constant is stabilized and the impedance is adjusted.

[0034] Next, a method of assembling female connector 10 will be described. Figures 4A to 4J show first to tenth steps of the assembly method. In the first step of Figure 4A, coaxial cable 100 is cut to a predetermined length. In the second step of Figure 4B, sheath 104 is stripped to expose braid 103. In the third step of Figure 4C, sleeve 106 is placed over braid 103, and sleeve 106 is crimped to braid 103.

[0035] 4D, the tip of the braid 103 is folded back onto the sleeve 106 and covered with the sleeve 106. The part covered with the sleeve 106 becomes the braid fold back 103a. After folding back, a part of the exposed insulator 102 is removed to expose the core wire 101.

[0036] In the fifth step of FIG. 4E, the female inner terminal 20 is attached (crimped) to the core wire 101. In the sixth step of FIG. 4F, the female inner terminal 20 is inserted into the female inner housing 30. At this time, the pair of flexible pieces 34 of the female inner housing 30 sandwich the insulator 102 of the coaxial cable 100, thereby correcting the core wire 101 so that the female inner terminal 20 is disposed at the center of the female inner housing 30. The female inner terminal 20 has a locking protrusion on its outer circumferential surface, and is positioned relative to the female inner housing 30 by engaging the locking protrusion with a recess provided on the inner periphery of the female inner housing 30. Therefore, the female inner terminal 20 is accommodated in the female inner housing 30 with the inclination of the core wire 101 corrected.

[0037] 4G, the female inner housing 30 and the female inner terminal 20 therein are inserted into the inner housing accommodating chamber 48 of the female outer terminal 40. At this time, the press-fit rib 33 of the female inner housing 30 contacts the inner wall of the inner housing accommodating chamber 48. Therefore, the inclination of the female inner terminal 20 and the core wire 101 in the female outer terminal 40 can be suppressed.

[0038] In an eighth step in Fig. 4H, the sheath crimping piece 42 and the braid crimping piece 43 are crimped to the coaxial cable 100, thereby achieving the state in Fig. 2. In a ninth step in Fig. 4I, the assembly (female connector 10) assembled up to Fig. 4H is inserted into the female outer housing 11. This assembly is held in the female outer housing 11 by a lance provided in the female outer housing 11 being engaged with the cylindrical portion 45 of the female outer terminal 40. In a tenth step in Fig. 4J, a spacer 12 is attached from the underside of the female outer housing 11, thereby preventing the lance from being displaced, and the female connector 10 is completed.

[0039] Second embodiment 5 to 7 show the female connector 10 of the second embodiment, and FIG. 5 corresponds to FIG. 1 of the first embodiment, FIG. 6 corresponds to FIG. 2, and FIG. 7 corresponds to FIG. 3. In this embodiment, the above-mentioned flexible piece 34 is not provided on the female inner housing 30. Even in this embodiment, when the female inner housing 30 covering the female inner terminal 20 is accommodated in the inner housing accommodation chamber 48 of the female outer terminal 40, the press-fit rib 33 contacts the inner wall of the inner housing accommodation chamber 48. Therefore, the inclination of the female inner terminal 20 and the core wire 101 in the female outer terminal 40 can be suppressed. Therefore, the impedance between the female inner terminal 20 and the female outer terminal 40 can be stabilized. The stabilization of the impedance can improve the transmission performance of the female connector 10.

[0040] The first to fifth steps of the method for assembling the female connector 10 of the second embodiment are common to the first embodiment (FIGS. 4A to 4E). FIGS. 8A to 8E show the sixth to tenth steps of the method for assembling the second embodiment. These steps are also almost common to the first embodiment, but in the sixth step of FIG. 8A, unlike FIG. 4F, the insulator 102 is not sandwiched by the flexible pieces 34. The other steps are common to the first embodiment.

[0041] The present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and appropriate modifications, improvements, etc. are possible. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited. For example, in the above-described embodiments, the press-fit rib 33 is provided on the female inner housing 30, but the press-fit rib may be provided on the male inner housing.
