[0009] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0010] For convenience of explanation, "front," "rear," "left," "right," "upper," and "lower" are defined below as shown in Figures 1 to 10. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to each other. The left-right direction corresponds to the "width direction" of the present invention.

[0011] As shown in Fig. 1, the female connector 1 includes an outer housing 2 and a female module 3. The outer housing 2 is a housing made of resin that houses the female module 3, which will be described later.

[0012] As shown in Figure 2, the female module 3 has a metal inner terminal 5 attached to the end of the twisted pair cable 4, a resin inner housing 6 that houses the inner terminal 5, and a metal outer terminal 7 that houses the inner housing 6.

[0013] The twisted pair cable 4 includes a twisted electric wire 41 formed by twisting two electric wires 411, 411 together, and an insulating sheath 42 that covers the twisted electric wire 41.

[0014] The sheath 42 at the end of the twisted pair cable 4 is removed, exposing the end of the twisted electric wire 41. The coverings 412 at the end of the two electric wires 411, 411 constituting the twisted electric wire 41 are removed, exposing the core wires 413. Two inner terminals 5 are provided. The two inner terminals 5 are electrically connected to the core wires 413 of the two electric wires 411, 411 constituting the twisted electric wire 41, respectively.

[0015] The inner terminal 5 has a terminal connecting portion 51, a core wire crimping piece 52, and a covering crimping piece 53. The terminal connecting portion 51 is connected to a terminal of a mating connector. In this embodiment, the terminal connecting portion 51 is in the shape of a box-shaped female terminal and is provided with a locking portion 511 that protrudes downward at its rear end. The locking portion 511 locks with a locking portion 612A provided on the inner housing 6, which will be described later. The core wire crimping piece 52 is provided rearward of the terminal connecting portion 51 and is crimped to the core wire 413 of the electric wire 411. The covering crimping piece 53 is provided rearward of the core wire crimping piece 52 and is crimped to the covering portion 412 of the electric wire 411. The inner terminals 5 are accommodated in the inner housing 6 aligned in the left-right direction.

[0016] 2 and 3, the inner housing 6 has a first accommodating portion 61 that accommodates the core wire crimping pieces 52 and the coating crimping pieces 53, and a second accommodating portion 62 that communicates with the first accommodating portion 61 and accommodates the terminal connecting portion 51. As shown in Fig. 2, the first accommodating portion 61 has a main body portion 611 that is provided in a gutter shape and is open downward and in the front-to-rear direction, a lid portion 612 that covers the downward opening of the main body portion 611, and a hinge portion 613 that is provided at the front end of the lid portion 612 and closes the lid portion 612 so that it can rotate freely around an axis that extends in the left-to-right direction.

[0017] The lid 612 is provided with a locking portion 612A. With the lid 612 open, the inner terminal 5 is housed in the inner housing 6, and then the lid 612 is closed. When the lid 612 is closed, the locking portion 612A is positioned rearward of the locking portion 511, and the locking portion 612A and the locking portion 511 are locked together in the front-to-rear direction. This prevents the inner terminal 5 from falling out of the inner housing 6.

[0018] As shown in FIG. 3, recesses 61A are provided on the left and right outer surfaces of the first accommodating portion 61. The recesses 61A extend to the upper end of the first accommodating portion 61. A pair of positioning ribs 61B, 61B for positioning an upper shell 71 (described later) is provided on an inner surface facing the recesses 61A in the front-rear direction. A recess 61C is provided on the left and right outer surfaces of the first accommodating portion 61. The recesses 61C extend to the lower end of the first accommodating portion 61. A pair of positioning ribs 61D, 61D for positioning a lower shell 72 (described later) is provided on an inner surface facing the recesses 61C in the front-rear direction. The recesses 61A are provided rearward and above the recesses 61C.

[0019] Further, on the left and right outer surfaces of the first accommodating portion 61, there are provided locking recesses 61E that lock onto the upper shell 71 and locking protrusions 61F that lock onto the lower shell 72. The locking recesses 61E are provided forward of the recesses 61A and rearward of the recesses 61C. The locking protrusions 61F are provided forward of the recesses 61C.

[0020] The second accommodating section 62 is formed in a rectangular tubular shape. The width of the second accommodating section 62 in the left-right direction (= the intersecting direction intersecting with the longitudinal direction (= the front-rear direction) of the twisted pair cable 4) is set to be shorter than the width of the first accommodating section 61 in the left-right direction.

[0021] 2 and 4, the outer terminal 7 has an upper shell 71 (first terminal portion) and a lower shell 72 (second terminal portion) that are divided in the vertical direction. The upper shell 71 and the lower shell 72 are formed by punching and pressing a single metal plate. In this embodiment, the thickness of the lower shell 72 is made thicker than the thickness of the upper shell 71. As shown in FIGS. 4 and 5, the upper shell 71 has a shell main body 711 that covers the inner housing 6 and a cable crimping piece 712 that is crimped to the twisted pair cable 4.

[0022] 5, the shell main body 711 has a bottom plate 713 and a pair of standing plates 714, 714 extending downward from both left-right (width) sides of the bottom plate 713. The left-right width of the portion of the bottom plate 713 that covers the second housing section 62 is shorter than the left-right width of the portion that covers the first housing section 61. Each of the pair of standing plates 714, 714 has a first standing plate portion 714A on the rear side of the portion that covers the second housing section 62, a second standing plate portion 714B on the front side, and a third standing plate portion 714C that covers the first housing section 61. The standing plates 714 are arranged so that their heights increase in the order of the third standing plate portion 714C, the first standing plate portion 714A, and the second standing plate portion 714B.

[0023] A positioning protrusion 715 is provided on the inner surface of the first upright portion 714A. The positioning protrusion 715 is provided by pressing the first upright portion 714A inward. The positioning protrusion 715 is provided with inclined surfaces S1 on side surfaces facing each other in the front-rear direction, the protruding height of which increases as the positions approach each other. As shown in FIG. 7, when the upper shell 71 is attached from above the inner housing 6, the positioning protrusion 715 is inserted into the recess 61A, and the inclined surfaces S1 are pressed by the positioning rib 61B, thereby positioning the upper shell 71 in the front-rear direction.

[0024] As shown in Fig. 5, the inner surface of the first upright portion 714A is provided with a locking protrusion 716 that is locked in the locking recess 61E in the vertical direction. The locking protrusion 716 is formed by pressing the first upright portion 714A inward. The locking protrusion 716 is provided forward of the positioning protrusion 715. As shown in Fig. 8, when the upper shell 71 is attached from above the inner housing 6, the locking protrusion 716 is inserted into the locking recess 61E, and the locking recess 61E and the locking protrusion 716 are locked in the vertical direction.

[0025] 5 and 8, a first inclined surface S31 is provided on the inner surface of the tip of the pair of first upright plate portions 714A, 714A, and the thickness becomes thinner as it approaches the lower shell 72. As shown in Fig. 10, an inclined surface is provided at the tip of the pair of third upright plate portions 714C, 714C to remove the corners, but basically the thickness is constant from the bottom plate 713 to the tip.

[0026] 4 and 6, the lower shell 72 has a shell main body 721 that covers the inner housing 6, and a cable crimping piece 722 that is crimped to the twisted pair cable 4. Note that in FIG. 6, the cable crimping piece 722 is shown in a simplified form, showing the shape after crimping.

[0027] 6, the shell main body 721 has a bottom plate 723 and a pair of upright plates 724, 724 standing upward from both left and right (width) sides of the bottom plate 723. The left and right width of the bottom plate 723 is the same for both the portion covering the first housing section 61 and the portion covering the second housing section 62. The pair of upright plates 724, 724 has a first upright plate portion 724A on the rear side of the portion covering the first housing section 61, a second upright plate portion 724B on the front side, and a third upright plate portion 724C covering the second housing section 62. The third upright plate portion 724C, the second upright plate portion 724B, and the first upright plate portion 724A are arranged in increasing height order.

[0028] A positioning protrusion 725 is provided on the inner surface of the second upright portion 724B. The positioning protrusion 725 is provided by pressing the second upright portion 724B inward. The positioning protrusion 725 is provided with inclined surfaces S2 on side surfaces facing each other in the front-rear direction, the protruding height of which increases as the positioning protrusion 725 approaches the side surfaces. As shown in FIG. 7, when the lower shell 72 is attached from the bottom of the inner housing 6, the positioning protrusion 725 is inserted into the recess 61C, and the inclined surfaces S2 are pressed by the positioning rib 61D, thereby positioning the lower shell 72 in the front-rear direction.

[0029] As shown in Fig. 6, an inner surface of the second upright portion 724B is provided with a locking protrusion 726 that is locked with the locking protrusion 61F in the up-down direction. The locking protrusion 726 is provided forward of the positioning protrusion 725. As shown in Fig. 9, when the lower shell 72 is attached from the bottom of the inner housing 6, the locking protrusion 726 is positioned above the locking protrusion 61F, and the locking protrusion 726 and the locking protrusion 61F are locked with each other in the up-down direction.

[0030] 6 and 8, the outer surfaces of the tips of the pair of first upright plate portions 724A, 724A are provided with second inclined surfaces S32 that become thinner as they approach the upper shell 71. As shown in Fig. 10, the tips of the pair of third upright plate portions 724C, 724C are provided with inclined surfaces to remove corners, but the thickness is basically constant from the bottom plate 723 to the tips.

[0031] 8, when the upper shell 71 and the lower shell 72 are attached to the inner housing 6, the tips of the pair of first upright plate portions 714A, 714A and the tips of the pair of first upright plate portions 724A, 714A overlap in the thickness direction (left-right direction) so that the first inclined surface S31 and the second inclined surface S32 face each other. Also, as shown in Fig. 10, a portion of the pair of third upright plate portions 714C, 714C where the thickness is constant overlaps a portion of the pair of third upright plate portions 724C, 724C where the thickness is constant.

[0032] According to the embodiment described above, the tips of the pair of first upright portions 714A, 714A of the upper shell 71 and the tips of the pair of first upright portions 724A, 724A of the lower shell 72 overlap in the thickness direction so that the first inclined surface S31 and the second inclined surface S32 face each other. By overlapping the tips of the first upright portion 714A and the first upright portion 724A in the thickness direction in this way, it is possible to reduce the gap between the upper shell 71 and the lower shell 72. Furthermore, by opposing the first inclined surface S31 and the second inclined surface S32, the female connector 1 does not become larger by the thickness of the outer upper shell 71, and therefore can be made more compact.

[0033] According to the embodiment described above, the thickness of the lower shell 72 is made thicker than the thickness of the upper shell 71. This makes it possible to increase the thickness of the lower shell 72 and ensure the force with which the cable clamping pieces 722 provided on the lower shell 72 hold the twisted pair cables 4. Furthermore, by making the thickness of the upper shell 71 thinner, costs can be reduced.

[0034] According to the embodiment described above, the width of the bottom plate 713 of the upper shell 71 covering the second housing portion 62 is set to be shorter than the width of the portion covering the first housing portion 61. This makes it possible to achieve a compact size even when the portions of the third upright portions 714C, 724C with constant thicknesses are stacked in the thickness direction.

[0035] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0036] According to the embodiment described above, the thickness of the lower shell 72 is set to be thicker than the thickness of the upper shell 71, but this is not limited to this. The thicknesses of the upper shell 71 and the lower shell 72 may be set to be the same. Also, the thickness of the upper shell 71 may be set to be thicker than the thickness of the lower shell 72.
