Patent number: 10931056Abstract: A connector has parts that can be used in common as much as possible in different specifications to reduce cost and to facilitate parts management. In a first specification having a high shielding function, a terminal fitting (20) connected to a shielded electric wire (15) is accommodated in a dielectric (23). The dielectric (23) is surrounded by an outer conductor (40) that is connected to a braided wire (18). The second specification requires no shielding function, and thus the outer conductor (40) is not used. Rather, a sub-housing (70) having the same shape and size as the outer conductor (40) of the first specification is used. The sub-housing (70) is configured to accommodate and retain the terminal fitting (20) and is locked in a same retained state as in the first specification when accommodated in a common housing (10) used in both specifications.Type: GrantFiled: October 23, 2019Date of Patent: February 23, 2021Inventors: Hajime Matsui, Yasuo Omori, Hiroyoshi Maesoba, Toshifumi Ichio, Kimiyasu Okumura, Masaaki Tabata, Ryutaro Yamazaki, Hiroshi Kobayashi, Motoya Hara

Patent number: 10819071Abstract: A connector is capable of replacing an STP cable (10B) and a UTP cable (10A) without a large structural change. UTP connection terminals (21A) are accommodated in accommodating portions (26) of a UTP dielectric (22A) that are close to each other in a width direction. Thus, elastic contact pieces (32) thereof are located inside and close to each other in the width direction, while receiving portions (31) are located outside and spaced from each other in the width direction. STP connection terminals (21B) are accommodated in accommodating portions (26) of an STP dielectric (22B) that are spaced more apart in the width direction than those of the UTP dielectric (22A). Thus, elastic contact pieces (32) thereof are located outside and are spaced from each other in the width direction, while receiving portions (31) thereof are located inside so as to be close to each other in the width direction.Type: GrantFiled: September 21, 2017Date of Patent: October 27, 2020Inventors: Hiroyoshi Maesoba, Toshifumi Ichio, Kimiyasu Okumura, Hiroshi Kobayashi, Motoya Hara, Ryutaro Yamazaki

Patent number: 10763600Abstract: The connector structure selectively uses either a UTP connector or an STP connector. The UTP connector includes UTP connection terminals connected to respective electric wires of a UTP cable and a UTP dielectric having a pair of housing portions in which the UTP connection terminals are housed. The STB connector includes STP connection terminals connected to respective electric wires of an STP cable and an STP dielectric having a pair of housing portions in which the STP connection terminals are housed. In the UTP dielectric, at least a partition wall for partitioning the pair of housing portions is made of a material having a relatively high dielectric constant. In the STP dielectric, at least a partition wall for partitioning the pair of housing portions is made of a material having a relatively low dielectric constant.Type: GrantFiled: April 23, 2019Date of Patent: September 1, 2020Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Hiroyoshi Maesoba, Toshifumi Ichio, Kimiyasu Okumura, Hiroshi Kobayashi, Motoya Hara, Ryutaro Yamazaki

Patent number: 10734748Abstract: A male internal conductor and a female internal conductor are reliably connected. When female-side and male-side dielectric bodies (16, 41) approach each other in an opposing positional relationship, a tab (32) of a male internal conductor (30) is inserted into a female-side dielectric body (41) and connected to a female internal conductor (42). The female-side dielectric body (41) has an opposing surface (41S) facing the male-side dielectric body (16) and formed with a female-side positioning portion (47). The male-side dielectric body (16) has an opposing surface (22S) facing the female-side dielectric body (41) and formed with a male-side positioning portion (25) which is disposed ahead of the tab (32) and which can be fitted with the female-side positioning portion (47) in a state where the tab (32) is not in contact with the female-side dielectric body (41).Type: GrantFiled: December 25, 2017Date of Patent: August 4, 2020Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Tetsuya Miyamura, Masaaki Tabata, Yasuo Omori, Kimiyasu Okumura, Hiroshi Kobayashi, Ryutaro Yamazaki

Patent number: 10622747Abstract: A connector includes a housing (10) having a terminal accommodation chamber (11) formed therein, and a first terminal fitting (12) can be inserted into the terminal accommodation chamber (11). A retainer (20) can be assembled to the housing (10) at a temporary locking position and at a final locking position, and a terminal holding member (30) can be assembled to the housing (10). A second terminal fitting (40) is attached to the terminal holding member (30). Interference parts (24, 26) are formed in the retainer (20) and the terminal holding member (30), respectively. The interference parts do not interfere with each other when the retainer (20) is in the final locking position. However, the interference parts interfere with each other to prevent the terminal holding member (30) from being assembled to the housing (10) when the retainer (20) is in the temporary locking position.Type: GrantFiled: September 20, 2017Date of Patent: April 14, 2020Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuya Miyamura, Masaaki Tabata, Yasuo Omori, Hajime Matsui, Hiroshi Kobayashi, Motoya Hara, Ryutaro Yamazaki
