A vehicle electrical connector includes an outer shell, an inner shell, and a conductive assembly. The outer shell includes a groove and assembling channels. The assembling channel extends from an opening on an outer side of the groove toward an inner tubular wall surface of the groove. The inner shell is in the outer shell and includes a base and a casing. The casing extends outward from one side of the base. The inner shell includes buckle blocks outside the casing. The buckle block is guided in the assembling channel through a path of the assembling channel, so that the buckle block is positioned in the assembling channel. Hence, after the inner shell is axially inserted into the outer shell and then rotated into a predetermined position, the inner shell and the outer shell can be stably held with each other.

A coaxial connector includes a plug and a receptacle that are electrically connectable to each other. The plug includes a first contact, a holder, a first tubular shell, and a shield member. The receptacle includes a second contact, a case, and a second tubular shell. The second contact includes a bottom portion, a pair of standing portions, and an extension. The pair of standing portions include respective contact portions having a wide shape and can clamp an end portion of the first contact. The extension includes a tip portion that is to be fixed to a substrate, a hold that is held by the case, and an elastic portion that is elastically deformable. The elastic portion can undergo elastic deformation in a direction orthogonal to a direction in which the contact portions extend.

A coaxial connector is provided. The coaxial connector includes a shell, a core body, and a fixing member. The shell has a central passage. The shell includes a first annular portion, a second annular portion, an annular engaging portion, and an annular abutting portion. The fixing member has a thru-hole. The fixing member includes a first portion, a second portion, and an engaging portion. The core body fixedly penetrates through the thru-hole of the fixing member. An inner diameter of the annular engaging portion gradually increases from one end of the shell to another end of the shell. The annular engaging portion has a first annular inclined surface, and the fixing member has a second annular inclined surface. The fixing member is engaged in the central passage, and the first annular inclined surface and the second annular inclined surface abut against each other.

A coaxial connector is provided. The coaxial connector includes a shell, a first fixing member, a second fixing member, and a core body. The first fixing member and the second fixing member are disposed in a fixing thru-hole of the shell. One end of the first fixing member abuts against one end of the second fixing member. One portion of the core body is disposed in the first fixing member and the second fixing member. An inner diameter of a first inner engaging portion of the first fixing member changes with a length thereof, and an inner diameter of a second inner engaging portion of the second fixing member is uniform. An outer diameter of an engaging portion of the core body changes with a length thereof, and an outer diameter of an auxiliary engaging portion of the core body is uniform.

A diagnosis plug-in connection comprising an electrical plug connector and a mating electrical plug connector. The electrical plug connector comprises a diagnosis module with an oaten conductor contact and an inner conductor contact within the outer conductor contact. The mating plug connector comprises a diagnosis head with an electrically conductive spring cage, which is designed for electrical and mechanical connection to the outer conductor contact of the diagnosis module of the plug connector. The spring cage electrically and mechanically contacts the inner conductor contact of the diagnosis module of the plug connector when the plug connector is plugged together with the mating, plug connector.

It is aimed to provide a connector device excellent in the reliability of a connecting operation. A connector device (A) is provided with a second housing (21) to be mounted on a second circuit board (C), a plurality of fixed terminal units (28) to be mounted in the second housing (21) and connected to the second circuit board (C), a plurality of movable terminal units (35) individually rockable with the plurality of fixed terminal units (28) as fulcrums and to be being individually connected to a plurality of first terminal units (16), and a coupling member 50 including a hooking portion (51) to be hooked to the plurality of movable terminal units (35), the coupling member 50 integrally rocking the plurality of movable terminal units (35).

The present invention relates to a fixed connector including a body fixedly inserted into a substrate, a signal pin having one side inserted into the body and the other side extending from the one side to be disposed on the substrate, and a dielectric coupling the signal pin and the body, wherein a portion of the signal pin has an L shape to be in contact with the substrate, and the portion of the signal pin is exposed to an outside of the body.

A connector includes: a cylindrical terminal; an internal terminal; and a housing. The cylindrical terminal has an engagement portion of its one edge portion and its opposite other edge portion. The one edge portion has a first reduced thickness portion at its circumferential end portion. The first reduced thickness portion has a first protrusion protruding inwardly in a radial direction and extending in an axial direction. The other edge portion has a second reduced thickness portion. The second reduced thickness portion has a second protrusion protruding outwardly in the radial direction and extending in the axial direction. The engagement portion is configured by overlapping the first reduced thickness portion and the second reduced thickness portion and further by locating the first protrusion and the second protrusion to face each other in the circumferential direction to allow an engagement between them in the circumferential direction.
