Connector inserts and connector receptacles that have a small form factor, readily mate when brought into proximity to each other, and disconnect when subjected to a non-axial force.
US10355400B2 Connector device
The connector device includes a first connector in which a first conductive member is housed in a first housing chamber, a second connector including a second housing chamber, and a cover, wherein the second housing chamber has a first housed position of the holding member of when an energization circuit is in an energized state, and a second housed position of the holding member of when the energization circuit is in a broken state, the holding member includes a non-contact portion that does not come into contact with a protruded body of the cover in a case of the first attachment state, and a pushed portion pushed by the protruded body to the second housed position in a case of the first housed position and in a case where the cover is attached in the second attachment state to the second opening.
US10355399B2 Cable connector having a shielding sleeve and method for producing the same
The invention relates to a cable connector (6). It has a shielding sleeve (2) having a first portion with a first opening and having a second portion with a second opening which is angled relative to the first portion. The first portion furthermore has a third opening which is opposite the first opening on the longitudinal axis of the first portion. The second portion has a slot-shaped opening which connects the second opening to the third opening. A cable (3) is guided through the first opening and through the second opening of the shielding sleeve (2). The cable connector (6) can be produced by a first end of the cable (3) being introduced through the third opening into the first portion of the shielding sleeve (2) and then being guided out of this portion again through the first opening. The cable (3) is finally bent such that a part of the cable (3) is moved through the slot-shaped opening into the second portion of the shielding sleeve (2) and a second end of the cable (3) projects out of the second opening of the shielding sleeve (2).
US10355397B2 Rubber plug and waterproof connector
A rubber plug (10) includes a mat-like rubber plug body (12) with sealing holes (11) for receiving a wire with terminal (95) in a liquid-tight manner. Rounded corner parts (13) protruding out on the rubber plug body (12). Outer peripheral lips (18) are provided circumferentially on an outer periphery of the rubber plug body (12) and inner peripheral lips (19) are provided circumferentially on inner peripheries of the sealing holes (11). Lightening portions (21) are provided for the outer peripheral lips (18) in base end parts of the outer peripheral lips (18) and parts facing the inner peripheral lips (19) of the sealing holes (11) near the corner parts (13) of the rubber plug body (12). The lightening portions (21) are recessed more inward than regions (22) adjacent in a circumferential direction.
US10355392B2 Connector with a housing, an array of terminals and protection walls projecting from body at opposite ends of the array of terminals
A connector (10) has a housing (20) including a body (21). A work hole (23) long in a lateral direction penetrates through the body (21). Terminals (30) are held in the housing (20) and are arranged side by side in the lateral direction in the work hole (23). Each terminal (30) includes an embedded portion (31) embedded in the housing (20), an internal connecting portion (32) connected to the embedded portion (31) and disposed inside the work hole (23) and an external connecting portion (33) connected to the internal connecting portion (32) and disposed outside the work hole (23). Protection walls (22) project from the body (21) at both sides of a terminals (30). Tip parts of the protection walls (22) are more distant from the body (21) than the external connecting portions (33) in a penetration direction of the work hole (23).
US10355389B2 High-current electrical terminal
An electrical-terminal includes a planar blade-shaped isolator and a conductor. The planar blade-shaped isolator is formed of a dielectric material having a spine, a tip, and a web. The spine extends along a longitudinal-axis. The tip extends along a lateral-axis, and the web extends from the spine and terminates at the tip. The web defines a slot extending in the lateral direction from and normal to the spine. The conductor has a first-side that overlays a second-side and defines a U-shaped bend and a gap between the first-side and the second side. The U-shaped bend is aligned parallel to and opposite the spine. The conductor includes a conductive stand-off located intermediate the first side and the second side of the conductor. The conductive stand-off is disposed within the slot of the web such that the first-side and the second-side are in further electrical contact through the conductive stand-off.
