[0009] [Description of embodiments of this disclosure] First, the implementation methods of this disclosure are listed and explained. The connector disclosed herein, (1) It comprises: an inner conductor connected to a wire; a dielectric body housing the inner conductor; and a conductive impedance adjustment member installed on the wire, wherein the inner conductor has a base and an insulating tube that stands from the base and is pressed against the covering portion of the wire, and the insulating tube has an inclined portion at an end edge on the side opposite to the impedance adjustment member that tilts toward the impedance adjustment member as it moves away from the base.

[0010] Based on this configuration, the amount by which the insulating cylinder can tilt toward the inclined portion towards the impedance adjustment member can expand the impedance adjustment range, thus improving the transmission performance.

[0011] (2) Preferably, the inclined portion is inclined backward as it moves upward from the base, and the wire has a portion that is inclined downward as it moves backward between the insulating tube and the impedance adjustment member.

[0012] According to this configuration, the inclined part and the impedance adjustment member can be positioned in a parallel or nearly parallel state, so the impedance variation can be reduced and the transmission performance can be improved.

[0013] [Details of the embodiments of this disclosure] The following is a reference to the appendix. Figure 1 Specific examples of embodiments of this disclosure will be described below. Furthermore, the invention is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as indicated by the claims.

[0014] Regarding the connector 10 in this embodiment, an example is a shielded connector that connects to the end of the cable 11 used for transmitting communication signals. For example... Figure 1As shown, connector 10 includes an impedance adjustment member 12, an inner conductor 13, a dielectric body 14, an outer conductor 15, an outer conductor cover 16, and a housing 17. Connector 10 engages with a counterpart connector 80. Regarding the counterpart connector 80, a shielded connector that connects to the end of cable 11 is also shown. Furthermore, in the following description, regarding the front-to-back direction, the side where connector 10 engages with counterpart connector 80 is designated as the front side. The vertical direction is based on the vertical direction of each figure.

[0015] like Figure 1 As shown, the cable 11 includes two wires 18, a braided shield 19 that covers the outer circumference of each wire 18, and an insulating sheath 21 that covers the outer circumference of the shield 19. The wires 18 are sheathed wires, consisting of conductive core wires 22 and an insulating sheath 23 that covers the outer circumference of the core wires 22.

[0016] At the end of cable 11, the sheath 21 is removed, exposing each wire 18. The end of the shield 19 is folded back from the end of the sheath 21 and exposed on the outer periphery of the sheath 21.

[0017] The wire 18 has an exposed portion 24 extending to the outside, located forward of the end of the sheath 21 (the folded-back portion of the shield 19). For example... Figure 3 , Figure 5 as well as Figure 6 As shown, the exposed portion 24 has a core wire exposed portion 25 consisting of a core wire 22 exposed at the front end by removing the covering portion 23, and a covering portion exposed portion 26 that exposes the covering portion 23 between the core wire exposed portion 25 and the impedance adjustment member 12.

[0018] <Impedance adjustment component> The impedance adjustment component 12 is formed by bending a conductive metal plate, etc. For example... Figure 4 As shown, the impedance adjustment member 12 has: two adjustment main bodies 27, which are installed on the covering part 23 of the exposed part 26 of the covering part of each wire 18; and a connecting part 28, which connects each adjustment main body 27.

[0019] Each adjustment body 27 is formed into a C-shaped cylindrical section that covers the outer peripheral surface of the covering portion 23 near the sheath 21 in the circumferential direction of the exposed covering portion 26. The length of the adjustment body 27 in the front-rear direction is shorter than the length of the exposed covering portion 26 in the front-rear direction.

[0020] The connecting portion 28 is curved in an upward bulging shape, connecting each adjustment body portion 27 in the left-right direction. The connecting portion 28 is formed such that the front portion is wider in the left-right direction compared to the rear portion. Therefore, the front portion of the impedance adjustment member 12 is wider in the left-right direction compared to the rear portion.

[0021] <Inner conductor> The inner conductor 13 is formed by bending a conductive metal plate, etc. For example... Figure 1 and Figure 5 As shown, the inner conductor 13 is a female terminal, having a square cylindrical terminal connection portion 29, an open cylindrical wire spool 31 connected to the rear of the terminal connection portion 29, and an open cylindrical insulating tube 32 connected to the rear of the wire spool 31. Figure 2 As shown, the terminal connection 29 is electrically connected to the inner conductor 84 of the counterpart connector 80 when the connector 10 and the counterpart connector 80 are engaged.

[0022] Additionally, the inner conductor 13 has a strip-shaped base 33 extending along its entire length in the front-to-back direction. The bobbin 31 has a pair of bobbin sheets 34 rising from the left and right sides of the front-to-back center of the base 33. (Example...) Figure 5 As shown, each coil spool 34 is wound around the exposed core portion 25 of the wire 18. Thus, the coil 31 is crimped and electrically connected to the exposed core portion 25. Similarly, the insulating cylinder 32 has a pair of insulating coils 35 standing upright on the left and right sides of the rear end portion of the base 33. Each insulating coil 35 is wound around the exposed sheath portion 26 of the wire 18. The insulating cylinder 32 is crimped and mechanically connected to the exposed sheath portion 26.

[0023] The bottom surface 55 of the insulating cylinder 32 is the bottom surface of the rear end of the base 33, such as Figure 6 As shown, in the crimped state, it is located at a position lower than the bottom surface 56 of the spool 31 and is arranged along the front-to-back direction.

[0024] like Figure 5 As shown, each insulating cylindrical sheet 35 has a straight edge 36 and a tapered edge 37 on its opposing edges in a crimped state. The straight edges 36 of each insulating cylindrical sheet 35 are arranged parallel to each other in the front-rear direction in the crimped state. The tapered edges 37 of each insulating cylindrical sheet 35 are arranged obliquely, expanding from the straight edges 36 in the left-right direction towards the front. Furthermore, as... Figure 6 As shown, the portion of the front of the insulating tube sheet 35 with a tapered edge 37 becomes a thickness reduction portion 57 that faces forward to reduce the thickness of the plate when viewed from the side in the crimped state.

[0025] In addition, such as Figure 6As shown, each insulating tube 35 has an inclined portion 39 at its rear edge that slopes backward as it moves upward in the crimped state. Specifically, in the side view of the crimped state, the inclined portion 39 slopes backward at an angle α of 20 to 40 degrees, preferably 30 degrees, relative to the vertical direction from the rear end of the bottom surface 55 to the rear end of the upper surface of the insulating tube 35. The inclined portion 39 is formed by deformation with a crimping die (not shown) during crimping to the wire 18, or by a metal sheet stamping process during the formation of the inner conductor 13. Except for the portion with the tapered edge 37 (upper end), the insulating tube 35 is shaped to widen in the vertical direction as it moves upward, thanks to the inclined portion 39. Furthermore, two inner conductors 13 are provided in the connector 10 corresponding to the two wires 18.

[0026] <Dielectric> The dielectric 14 is formed into a rectangular parallelepiped shape, elongated in the front-to-back direction, using an insulating synthetic resin material. For example... Figure 1 As shown, the dielectric 14 is formed by combining the lower member 41 and the upper member 42 in the vertical direction. The two inner conductors 13, in connection with the wire 18, are housed in the dielectric 14 in the horizontal direction.

[0027] <External Conductor> The outer conductor 15 is formed by bending or other processes on a conductive metal plate. For example... Figure 1 As shown, the outer conductor 15 has a rectangular fitting tube portion 43 that is long in the front-to-back direction and a shielding connection portion 44 that is connected to the shielding body 19 of the cable 11.

[0028] The dielectric 14 is inserted from the rear into the fitting sleeve portion 43. When the dielectric 14 is housed in the fitting sleeve portion 43, the inner conductor 13 is electrically insulated from the fitting sleeve portion 43 by the dielectric 14. An elastic contact portion 45 that can elastically deform is formed in the fitting sleeve portion 43, which can contact the outer conductor 86 of the other connector 80 (described later).

[0029] The shielding connection portion 44 is formed in the shape of a plate extending rearward from the lower rear edge of the fitting cylinder portion 43. For example... Figure 2 As shown, the shielding connection part 44 is disposed below the shielding body 19 and is connected to the shielding body 19 by the pressing force of the outer conductor cover 16.

[0030] <Outer Conductor Cover> The outer conductor cover 16 is formed by bending a conductive metal plate, etc. For example... Figure 2 As shown, the rear part of the fitting cylinder 43 is positioned inside the front part of the outer conductor cover 16. (As indicated...) Figure 1 As shown, a square opening 46 and a housing locking portion 47 protruding upward from the front edge of the opening 46 are formed on the upper wall of the front part of the outer conductor cover 16.

[0031] A shielding cylinder portion 48 is formed at the rear of the outer conductor cover 16. For example... Figure 2 As shown, the shielding cylinder portion 48 has a shielding connection portion 44 for the outer conductor 15 disposed on its inner side, and is crimped to the shielding body 19 of the cable 11. Furthermore, Figure 1 For convenience, the shielding cylinder portion 48 shown is depicted in its deformed form after being crimped with the shielding body 19 of the cable 11. In fact, the shielding cylinder portion 48 is formed as an open cylinder before deformation.

[0032] <Shell> The casing 17 is made of synthetic resin, such as Figure 2 As shown, the module storage section 51 extends through the front-to-back direction. A spear-shaped portion 52 is formed protruding forward on the upper surface of the rear inner wall of the module storage section 51. The spear-shaped portion 52 is elastically deformable in the up-and-down direction.

[0033] The module storage section 51 houses the module 50, which is formed by assembling the inner conductor 13, dielectric 14, outer conductor 15, and outer conductor cover 16. For example... Figure 2 As shown, the spear-shaped portion 52 is inserted into the opening hole 46 and locked with the housing locking portion 47, thereby preventing the module 50 from falling out of the module storage portion 51. In addition, a locking arm 53 is formed on the upper wall of the housing 17.

[0034] <Partner Connector> like Figure 2 As shown, the counterpart connector 80 includes a counterpart inner conductor 84 as a male terminal, a counterpart dielectric 85 housing the counterpart inner conductor 84, a counterpart outer conductor 86 surrounding the counterpart dielectric 85, and a counterpart housing 88 that can be fitted into the housing 17. The counterpart inner conductor 84 is connected to two wires 18 of the cable 11 respectively, and is insulated from the counterpart outer conductor 86 by the counterpart dielectric 85. A counterpart impedance adjustment member 87 is installed on each wire 18. The counterpart impedance adjustment member 87 has the same shape as the impedance adjustment member 12.

[0035] The inner conductor 84 has a tab 89 protruding forward. When the connector 10 and the connector 80 are engaged, the tab 89 of the inner conductor 84 is inserted into and electrically connected to the terminal connection portion 29 of the inner conductor 13. In addition, an inclined portion is also formed in the insulating sleeve of the inner conductor 84.

[0036] The outer conductor 86 of the other party is connected to the shield 19 of the cable 11. When the connector 10 and the other party connector 80 are engaged, the outer conductor 86 covers the outer periphery of the engagement sleeve 43 of the outer conductor 15, and its inner surface contacts the elastic contact portion 45.

[0037] The opposing housing 88 has a cylindrical cover 91. A locking protrusion 92 is formed on the inner surface of the upper wall of the cover 91. The housing 17 is fitted inside the cover 91 of the opposing housing 88. The housing 17 is held in a fitted state inside the cover 91 by locking the locking arm 53 with the locking protrusion 92.

[0038] <Function> like Figure 2 As shown, within module 50, the inner conductor 13 is arranged with its axis oriented in the front-to-back direction within the dielectric 14. Figure 3 As shown, the exposed portion 26 of the wire 18 is inclined downwards from the rear end of the inner conductor 13 (the inclined portion 39 of the insulating tube 35) to the end of the sheath 21 (the folded-back portion of the shield 19), becoming the inclined side of the inclined portion 39. The impedance adjustment member 12 is also inclined relative to the front-rear direction according to the inclination of the exposed portion 26. Here, compared with the existing trailing edge arranged along the vertical direction, the inclined portion 39 of the insulating tube 35 is inclined in a direction closer to the impedance adjustment member 12. Therefore, according to this embodiment, the impedance adjustment range is expanded by the inclination amount of the inclined portion 39. As a result, the impedance can be effectively reduced, and the transmission characteristics (communication characteristics) can be improved. Moreover, the impedance adjustment can be easily performed by adjusting the inclination angle α of the inclined portion 39.

[0039] Furthermore, in this embodiment, the exposed portion 26 of the wire 18's sheath also tilts downwards towards the inclined portion 39. Based on the tilt of the exposed portion 26, the impedance adjustment member 12 also tilts. Therefore, the inclined portion 39 of the insulating tube 35 and the front end of the impedance adjustment member 12 can face each other in a parallel or nearly parallel state, reducing impedance fluctuations and enabling high-speed transmission. The same relationship applies to the inclined portion of the insulating tube of the inner conductor 84 and the corresponding impedance adjustment member 87.

[0040] [Other embodiments of this disclosure] The embodiments disclosed herein should be considered illustrative in all respects, and not restrictive. In other embodiments, the inclined portion of the insulating tube is not inclined at a certain angle. For example, a step may be formed in the middle of the inclination, or it may be formed in a curved inclination. In other embodiments, the impedance adjustment member may not have a connecting part that connects the wires, or it may be a fastening ring that crimps the wires of the UTP cable.
