As shown in FIGS. 4 and 5, when the connector 100 and the mating connector 500 are mated, the covering portion 230 faces the peripheral wall portion 610 in the up-down direction. As shown in FIG. 9, the covering portion 230 has an upper end 232 in the up-down direction.

[0030] Referring to Fig. 9, the terminals 300 of this embodiment are made of metal. The terminals 300 are partially embedded and held in the holding member 200. However, the present invention is not limited to this, and it is sufficient that the terminals 300 are at least partially embedded and held in the holding member 200. As shown in Fig. 7, the terminals 300 form two terminal rows 250 spaced apart in the width direction. That is, the connector 100 has two terminal rows 250 spaced apart in the width direction, and each terminal row 250 is composed of terminals 300 lined up in the pitch direction. Referring to Figs. 4 and 5, the terminals 300 correspond to mating terminals 700, respectively.

[0032] As shown in Fig. 7, the first terminals 310 of the present embodiment correspond to the cover portions 230, respectively. The first terminals 310 of the two terminal rows 250 are arranged in a staggered manner. As shown in Fig. 10, the first terminals 310 have a first mounting portion 312 and a first main portion 318.

[0033] As shown in FIG. 10 , the first mounting portion 312 of this embodiment extends in a width direction that is perpendicular to both the up-down direction and the pitch direction. More specifically, the first mounting portion 312 does not have any bent portions and extends linearly outward in the width direction. The first mounting portion 312 extends linearly outward in the width direction from the first main portion 318. As can be seen from FIGS. 6 and 10 , the first mounting portion 312 is connected and fixed to the board 800 in a mounted state in which the connector 100 is mounted on the board 800. More specifically, the first mounting portion 312 is connected and fixed to a pad 810 on the board 800 in the mounted state.

[0034] 10, the covering portions 230 are located above the first mounting portions 312 in the vertical direction. More specifically, each covering portion 230 is located directly above the corresponding first mounting portion 312 in the vertical direction. The covering portions 230 partially cover the first mounting portions 312 from above. That is, each covering portion 230 partially covers the corresponding first mounting portion 312 from above.

[0035] As shown in FIG. 10, the first mounting portion 312 has a first carrier cut surface 314 as an end surface 3122 facing in the width direction.

[0036] 7 and 10, in any of the terminal rows 250, the first carrier cut surfaces 314 face outward in the width direction. The first carrier cut surfaces 314 are located outside the covering portions 230 in the width direction. More specifically, the first carrier cut surfaces 314 of the first terminals 310 are located outside the corresponding covering portions 230 in the width direction.

[0037] As shown in FIG. 10, the first mounting portion 312 has an upper surface 3124 .

[0038] 10, the upper surface 3124 of this embodiment faces upward in the vertical direction. The upper surface 3124 intersects with the vertical direction. That is, the upper surface 3124 is perpendicular to the vertical direction.

[0039] As shown in Fig. 10, the first main portion 318 in this embodiment extends from the first mounting portion 312. More specifically, the first main portion 318 extends upward in the up-down direction from the inner end of the first mounting portion 312 in the width direction, then bends to extend inward in the width direction, and then bends again to extend downward. The first main portion 318 has an inverted U-shaped cross section in a plane perpendicular to the pitch direction. A first contact portion 316 is provided on the first main portion 318.

[0040] 5, the first contact portion 316 of the present embodiment comes into contact with the mating terminal 700 when the connector 100 and the mating connector 500 are mated. More specifically, the first contact portion 316 comes into contact with the mating first contact portion 712 of the mating first terminal 710 in the mated state. As shown in FIG. 10, the first contact portion 316 is located above the first mounting portion 312 in the up-down direction.

[0041] As shown in FIG. 10, the first contact portion 316 is composed of an outer first contact portion 3162 and an inner first contact portion 3164 .

[0042] As shown in Fig. 10, the outer first contact portion 3162 in this embodiment faces outward in the width direction. The outer first contact portion 3162 is located outward of the inner first contact portion 3164 in the width direction. With reference to Figs. 7 and 9, the outer first contact portion 3162 of the first terminal 310 in the front terminal row 250 faces forward in the front-to-rear direction. With reference to Figs. 7 and 10, the outer first contact portion 3162 of the first terminal 310 in the rear terminal row 250 faces backward in the front-to-rear direction.

[0043] As shown in Fig. 10, the inner first contact portion 3164 of this embodiment faces inward in the width direction. The inner first contact portion 3164 is located inside the outer first contact portion 3162 in the width direction. The inner first contact portion 3164 defines the inner end of the first terminal 310 in the width direction. With reference to Figs. 7 and 9, the inner first contact portion 3164 of the first terminal 310 in the front terminal row 250 faces rearward in the front-to-rear direction. With reference to Figs. 7 and 10, the inner first contact portion 3164 of the first terminal 310 in the rear terminal row 250 faces forward in the front-to-rear direction.

[0044] 8 and 9, the second terminals 320 of the present embodiment correspond to the insulating protection portions 220, respectively. Referring to Fig. 7 and 9, the second terminals 320 of the two terminal rows 250 are arranged in a staggered manner. The second terminals 320 have a second mounting portion 322, a second main portion 328, and a non-mounting portion 324.

[0045] As shown in Fig. 9, the second mounting portion 322 in this embodiment extends in the width direction. More specifically, the second mounting portion 322 does not have any bent portions and extends linearly inward in the width direction. The second mounting portion 322 extends linearly inward in the width direction from the second main portion 328. As can be seen from Figs. 6 and 9, the second mounting portion 322 is connected and fixed onto the substrate 800 in the mounted state. More specifically, the second mounting portion 322 is connected and fixed to a pad 810 on the substrate 800 in the mounted state.

[0046] As shown in FIG. 9 , the second main portion 328 in this embodiment extends from the second mounting portion 322. More specifically, the second main portion 328 extends upward in the up-down direction from the outer end of the second mounting portion 322 in the width direction, then bends to extend outward in the width direction, and then bends again to extend downward. The second main portion 328 extends from the non-mounting portion 324. The second main portion 328 has an inverted U-shaped cross section in a plane perpendicular to the pitch direction. The second main portion 328 connects the second mounting portion 322 and the non-mounting portion 324 to each other. A second contact portion 326 is provided on the second main portion 328.

[0047] As shown in Fig. 4, the second contact portion 326 of the present embodiment comes into contact with the mating terminal 700 in the mated state. More specifically, the second contact portion 326 comes into contact with the second mating contact portion 722 of the second mating terminal 720 in the mated state. As shown in Fig. 9, the second contact portion 326 is located above the second mounting portion 322 in the vertical direction. The second contact portion 326 is located above the non-mounting portion 324 in the vertical direction.

[0048] As shown in FIG. 9, the second contact portion 326 is composed of an outer second contact portion 3262 and an inner second contact portion 3264.

[0049] As shown in Fig. 9, the outer second contact portion 3262 in this embodiment faces outward in the width direction. The outer second contact portion 3262 is located outward of the inner second contact portion 3264 in the width direction. With reference to Figs. 7 and 10, the outer second contact portion 3262 of the second terminal 320 in the front terminal row 250 faces forward in the front-to-rear direction. With reference to Figs. 7 and 9, the outer second contact portion 3262 of the second terminal 320 in the rear terminal row 250 faces rearward in the front-to-rear direction.

[0050] As shown in Fig. 9, the inner second contact portion 3264 in this embodiment faces inward in the width direction. The inner second contact portion 3264 is located inside the outer second contact portion 3262 in the width direction. With reference to Figs. 7 and 10, the inner second contact portion 3264 of the second terminal 320 in the front terminal row 250 faces rearward in the front-to-rear direction. With reference to Figs. 7 and 9, the inner second contact portion 3264 of the second terminal 320 in the rear terminal row 250 faces forward in the front-to-rear direction.

[0051] As shown in FIG. 9 , the non-mounting portion 324 of this embodiment extends in the width direction. More specifically, the non-mounting portion 324 does not have any bent portions and extends linearly outward in the width direction. The non-mounting portion 324 is located away from the second mounting portion 322 in the width direction. The non-mounting portion 324 is closer to the first mounting portion 312 than the second mounting portion 322. In other words, the distance between the first mounting portion 312 and the non-mounting portion 324 is shorter than the distance between the first mounting portion 312 and the second mounting portion 322. The insulating protection portion 220 is located below the non-mounting portion 324 in the up-down direction. More specifically, each insulating protection portion 220 is located directly below the non-mounting portion 324 of the corresponding second terminal 320 in the up-down direction. As shown in FIG. 7 , the non-mounting portion 324 is partially surrounded by the covering portion 230 in a plane perpendicular to the up-down direction. Two cover portions 230 are located on both sides of the non-mounting portion 324 in the pitch direction.

[0052] 9, the non-mounting portion 324 is located above the first mounting portion 312 in the up-down direction. That is, a large insulation distance is ensured from the first mounting portion 312 of the first terminal 310 to the non-mounting portion 324 of the adjacent second terminal 320. This prevents a short circuit between the first terminal 310 and the second terminal 320 due to the solder connecting the first mounting portion 312 and the pad 810 when the first mounting portion 312 is soldered to the pad 810 of the substrate 800 (see FIG. 6).

[0053] As shown in FIG. 9, the non-mounting portion 324 has an upper surface 3244 and a lower end 3246 .

[0054] As shown in Fig. 9, the upper surface 3244 of this embodiment faces upward in the vertical direction. As shown in Fig. 8, the upper end 232 of the covering portion 230 is In the vertical direction 7, upper end 232 of covering portion 230 may be located below upper surface 3244 of non-mounting portion 324. As shown in FIG. 7, upper surface 3244 is exposed to the outside of holding member 200. As a result, in connector 100 of the present embodiment, the size in the vertical direction of the portions near first mounting portion 312 and non-mounting portion 324 is reduced compared to when upper surface 3244 of non-mounting portion 324 is covered by holding member 200.

[0055] 4 and 9 , in the mated state, the peripheral wall 610 of the mating connector 500 faces the upper surface 3244 in the vertical direction. When the upper surface 3244 of the non-mounting portion 324 is covered by the holding member 200, the peripheral wall 610 faces a portion of the holding member 200 that covers the upper surface 3244 in the vertical direction in the mated state. That is, an assembly including a connector in which the upper surface 3244 of the non-mounting portion 324 is covered by the holding member 200 has a larger vertical size in the mated state than the assembly 10 of the present embodiment. In other words, the assembly 10 of the present embodiment has a smaller vertical size in the mated state than when the upper surface 3244 of the non-mounting portion 324 is covered by the holding member 200. This allows the distance between the board 800 on which the connector 100 is mounted and the board on which the mating connector 500 is mounted to be reduced, thereby enabling the miniaturization of a device including the assembly 10.

[0056] 8, the upper surface 3124 of the first mounting portion 312 and the lower end 3246 of the non-mounting portion 324 are located at the same position in the up-down direction. The lower end 3246 of the non-mounting portion 324 is partially covered by the insulating protection portion 220. This more reliably prevents short circuits between adjacent terminals 300 in the connector 100 of this embodiment. However, the present invention is not limited to this, and it is sufficient that the lower end 3246 of the non-mounting portion 324 is at least partially covered by the insulating protection portion 220. This more reliably prevents short circuits between adjacent terminals 300.

[0057] As shown in FIG. 9, the non-mounting portion 324 has a second carrier cut surface 325 as an end surface 3242 facing in the width direction.

[0058] As shown in Fig. 9, the second carrier cut surface 325 in this embodiment is located outside the insulating protection portion 220 in the width direction. Referring to Figs. 7 and 9, in any terminal row 250, the second carrier cut surface 325 faces outward in the width direction. The first carrier cut surface 314 and the second carrier cut surface 325 face in the same direction in the width direction. In the non-mounting portion 324, the second carrier cut surface 325 and its vicinity are exposed to the outside of the holding member 200.

[0059] 9, the first carrier cut surface 314 is farther from the second mounting portion 322 in the width direction than the second carrier cut surface 325. That is, the first mounting portion 312 extends outward in the width direction further than the non-mounting portion 324. This makes it easy to check the soldering state of the first mounting portion 312 when the first mounting portion 312 is soldered to the pad 810 of the substrate 800 in the connector 100 of this embodiment.

[0060] (Connector manufacturing method) An example of a method for manufacturing the connector 100 of this embodiment will be described in detail below.

[0061] 16 , a metal plate is punched and bent to prepare two first terminal intermediates 410. Each of the first terminal intermediates 410 is composed of a plurality of first terminal blanks 411 and a first carrier 412. The first terminal blank 411 has a portion 4112 that extends linearly outward in the width direction without being bent, and the outer end of the portion 4112 in the width direction is connected to the first carrier 412 by a first connecting portion 4122.

[0062] 16 , two second terminal intermediates 420 are prepared by punching and bending a metal plate. Each of the second terminal intermediates 420 includes a plurality of second terminal blanks 421 and a second carrier 422. The second terminal blanks 421 each have a portion 4212 that extends linearly outward in the width direction without bending, and the outer end of the portion 4212 in the width direction is connected to the second carrier 422 by a second connecting portion 4222. The first terminal intermediate 410 and the second terminal intermediate 420 together form two sets of terminal intermediates 400.

[0063] Next, in each set of terminal intermediate bodies 400, the second carrier 422 is placed directly on the first carrier 412 so that the first terminal blank 411 and the second terminal blank 421 are at the same position in the width direction. This brings the terminal intermediate bodies 400 into the state shown in Fig. 15. In each set of terminal intermediate bodies 400, the first terminal blanks 411 and the second terminal blanks 421 are arranged alternately in the pitch direction.

[0064] Thereafter, the first terminal blank 411 and the second terminal blank 421 are set in a mold (not shown) so that the two sets of terminal intermediates 400 face each other in the width direction, and resin is poured into the mold to mold the resin. This forms the holding member 200 and causes the holding member 200 to hold the first terminal blank 411 and the second terminal blank 421. That is, referring to Fig. 12, an intermediate 100A including an insert-molded intermediate 150A is manufactured.

[0065] 13 and 14, the first connecting portion 4122 and the second connecting portion 4222 are cut. As a result, the first terminal blank 411 becomes the first terminal 310, the cut surface of the first connecting portion 4122 becomes the first carrier cut surface 314, and the portion 4112 becomes the first mounting portion 312. Similarly, the second terminal blank 421 becomes the second terminal 320, the cut surface of the second connecting portion 4222 becomes the second carrier cut surface 325, and the portion 4212 becomes the non-mounting portion 324. In other words, the insert molding intermediate 150A becomes the insert molding body 150, and the connector 100 of the present embodiment is manufactured.

[0066] The above-described manufacturing method makes it possible to manufacture, in a single molding process, connector 100 of the present embodiment, which has two terminal rows 250. In connector 100 manufactured by the above-described manufacturing method, first carrier cut surface 314 and second carrier cut surface 325 face outward in the width direction in both terminal rows 250.

[0067] In the above-described manufacturing method, the portion 4112 that becomes the first mounting portion 312 and the portion 4212 that becomes the non-mounting portion 324 both extend linearly outward in the width direction without bending. Furthermore, in the above-described manufacturing method, the second carrier 422 to which the portion 4212 that becomes the non-mounting portion 324 is connected is placed directly on the first carrier 412 to which the portion 4112 that becomes the first mounting portion 312 is connected. As a result, in the connector 100 manufactured by the above-described manufacturing method, the upper surface 3124 of the first mounting portion 312 and the lower end 3246 of the non-mounting portion 324 are at the same position in the up-down direction.

[0068] In the above-described manufacturing method, the terminal intermediate 400 is composed of a first terminal intermediate 410 and a second terminal intermediate 420, and the first terminal blanks 411 of the first terminal intermediate 410 and the second terminal blanks 421 of the second terminal intermediate 420 are alternately arranged in the pitch direction. As a result, in the above-described manufacturing method, the distance between the first terminal blanks 411 and the distance between the second terminal blanks 421 can be ensured to be wider than the distance between the first terminal blanks 411 and the second terminal blanks 421. In other words, in the above-described manufacturing method, even if the distance between the first terminal blanks 411 and the second terminal blanks 421 is narrowed, a certain distance can be ensured between the first terminal blanks 411, and similarly, a certain distance can be ensured between the second terminal blanks 421. Therefore, even when manufacturing connector 100 with narrow pitch between terminals 300, it is easy to cut out and bend first terminal blank 411, which becomes first terminal 310, and to separate first terminal blank 411 from first carrier 412. Similarly, it is easy to cut out and bend second terminal blank 421, which becomes second terminal 320, and to separate second terminal blank 421 from second carrier 422. In other words, connector 100 of the present embodiment is easy to manufacture even when terminals 300 are spaced apart at a narrow pitch.

[0069] Although the present invention has been specifically described above using the embodiments, the present invention is not limited to these and various modifications are possible. Furthermore, a plurality of the above embodiments and modifications may be combined.

[0070] While the connector 100 of this embodiment has two terminal rows 250 spaced apart in the width direction, the present invention is not limited thereto, and the number of terminal rows 250 may be one. In this case, a plurality of first terminal blanks 411 connected to a first carrier 412 on one side in the width direction and a plurality of second terminal blanks 421 connected to a second carrier 422 on the same side in the width direction are set in a mold, and then the connector 100 having a single row of terminal rows 250 can be manufactured by insert molding in the same manner as the manufacturing method described above. This manufacturing method allows both the first carrier 412 and the second carrier 422 to be positioned on one side in the width direction of the mold, thereby making it possible to reduce the size of the mold used for insert molding compared to when the first carrier 412 and the second carrier 422 are positioned on both sides in the width direction of the mold. In other words, even a connector 100 having a single row of terminal rows 250 has a structure that is more suitable for insert molding. Note that, even in the connector 100 having a single terminal row 250, the first carrier cut surface 314 of the first terminal 310 and the second carrier cut surface 325 of the second terminal 320 face in the same direction in the width direction, as in the connector 100 of the present embodiment. Also, in the connector 100 having a single terminal row 250, the non-mounting portion 324 of the second terminal 320 is positioned higher than the first mounting portion 312 of the first terminal 310 in the up-down direction, as in the connector 100 of the present embodiment. This ensures a large insulation distance from the first mounting portion 312 of the first terminal 310 to the non-mounting portion 324 of the adjacent second terminal 320. As a result, even in the connector 100 having a single terminal row 250, when the first mounting portion 312 is soldered to the pad 810 of the substrate 800, a short circuit between the first terminal 310 and the second terminal 320 due to the solder connecting the first mounting portion 312 and the pad 810 is prevented.

[0071] In the terminal intermediate body 400 of the above-described embodiment, the first terminal blank 411 is connected to the first carrier 412, and the second terminal blank 421 is connected to the second carrier 422 that is separate from the first carrier 412. However, the present invention is not limited to this. The terminal intermediate body 400 may be configured so that the first terminal blank 411 and the second terminal blank 421 are connected to a common carrier. In this case, by providing a crank-shaped step when viewed from the pitch direction at the connection portion between the second terminal blank 421 and the carrier, the portion corresponding to the first carrier cut surface 314 and the portion corresponding to the second carrier cut surface 325 can be shifted up and down.
