The present disclosure provides a connector, which relates to the technical field of electrical connection devices, so as to solve the problem of poor connection stability of connectors in existing technologies. The connector includes a mounting base and a binding post, wherein the binding post has both sides symmetrically provided with a fixed fin, the mounting base defines thereon a mounting groove for mounting the binding post, two sides of the mounting groove define a limit groove, and the fixed fin is clamped in the limit groove so as to enable the binding post to be limited to the mounting groove. The connector according to the present disclosure has good connection stability and can effectively transmit current or signal, enabling an effective cooperation between connected devices.

A connector includes a housing having a fitting part that is inserted and fitted into a counterpart fitting part, a shield shell having a shell flange part disposed opposite a wall surface of a counterpart wall body with an interval therebetween, a first watertight member between the fitting part and the counterpart fitting part, and a second watertight member that is crushed between the shell flange part and a wall surface of the counterpart wall body. The housing has a housing flange part with an outer peripheral surface thereof disposed inside an outer peripheral edge of the shell flange part and outside an inner edge of the shell flange part, and with a contact surface with an annular shape in contact with the wall surface of the counterpart wall body.

Provided is a power conversion device, including: a casing that has a front surface with an opening; an insertion component including an insertion portion; and a gasket. The casing has an inner wall surface being in contact with the gasket and a casing-side guide surface. The insertion portion has an outer peripheral surface being in contact with the gasket and an insertion component-side guide surface. When a distance in the insertion direction between the front surface and an end of the casing-side guide surface, which is closer to the front surface in the insertion direction, is represented by L1 and a distance between an inner surface of the gasket in the insertion direction and a distal end of the insertion component-side guide surface in the insertion direction is represented by L2, the distance L2 is set larger than the distance L1.

A connector includes: a terminal fitting; an electric wire connected to the terminal fitting; a housing in which the terminal fitting is stored, the housing constituting a fitting part with a counterpart connector; a shield shell disposed so as to surround an outer periphery of the housing; and a seal member made of rubber and sandwiched between the housing and the shield shell. The seal member has a rubber hardness of 30 degrees or more and 50 degrees or less. A value obtained by dividing a compressed height, which is a difference between a first height of the seal member before being sandwiched between the housing and the shield shell and a second height of the seal member when being sandwiched between the housing and the shield shell, by the first height is 0.1 or more and 0.4 or less.

There is provided a connector including a seal member that seals a gap between an opening inner wall of an opening and a peripheral edge of a cover. The seal member includes a body portion having an annular shape along the peripheral edge of the cover, an extending portion that extends from an end portion of the body portion on a side of an outside along a cover surface of the cover, and a protruding portion that protrudes in a direction of intersecting with an extending direction of the extending portion and extends from the extending portion along the cover surface. The cover includes a recessed fitting portion into which the extending portion and the protruding portion of the seal member are fitted.

A connector includes a terminal fitting that is connected to a mating terminal fitting of a mating fitting space, a housing that includes a fitting wall fitted into the mating fitting space and a terminal accommodating section that accommodates the terminal fitting and is inserted into the mating fitting space together with the fitting wall, and an annular or tubular elastically deformable sealing member that fills an annular or tubular gap between an outer peripheral surface of the fitting wall and an inner peripheral surface of the mating fitting space in a circumferential direction at a fitting completion position of the fitting wall and the mating fitting space where positions of axial centers of the fitting wall and the mating fitting space are aligned with each other.

The electric device has a first seal part, including, between a first case and a second case, a groove portion prepared at one side and a projection portion prepared at another side, where those portions are joined by sealing material; a second seal part, including, between the opening part of the first case and a peripheral part of the connector, a groove portion prepared at one side and a projection portion prepared at another side, where those portions are joined by the sealing material; and a third seal part, including, among the first case, the second case, and the peripheral part of the connector, a groove portion prepared at one side and a projection portion prepared at another side, as a combination, or a projection portion prepared at one side and a groove portion prepared at another side, as a combination, where those portions are joined by the sealing material.

There is provided a connector including: a housing including a cylindrical wall portion; and a hollow annular front holder attached to the cylindrical wall portion to surround an outer periphery thereof. The front holder includes: a pair of first locking portions and a pair of operating portions arranged that are arranged to face with each other in a radial direction of the front holder. The connecter is configured such that: in a state where the front holder is fitted externally on the cylindrical wall portion, the pair of first locking portions is engaged with the cylindrical wall portion; and in response to an operation of displacing the pair of operating portions to approach with each other in the radial direction, the pair of first locking portions is displaced to release an engagement between the front holder and the cylindrical wall portion.

A connector includes: a terminal fitting; an electric wire connected to the terminal fitting; a housing in which the terminal fitting is stored; a shield shell disposed so as to surround an outer periphery of the housing; and a waterproof cover having a tubular shape and made of an elastic material, the waterproof cover being provided so as to surround an outer periphery of the shield shell and configured to be in close contact with the outer periphery of the shield shell. The shield shell is brought into close contact with a close-contact portion of the waterproof cover. The waterproof cover includes at least one protruding strip portion provided at the close-contact portion, the at least one protruding strip portion protruding from a tubular inner surface of the waterproof cover and extending in a peripheral direction.

An electrical connection plug, an electrical connection device and an electric. The electrical connection plug includes a first fixing plate, a mounting base, an electrical connection assembly and a plurality of plug-in assemblies, the electrical connection assembly and the plurality of the plug-in assemblies are all connected to the mounting base, and the mounting base is in floating connection with the first fixing plate. The electrical connection device includes an electrical connection socket and the above electrical connection plug, the electrical connection assembly and the plurality of plug-in assemblies are all connected to the electrical connection socket. The electric vehicle includes a battery pack, a vehicle body and the above electrical connection device, the electrical connection plug is connected to the vehicle body, and the electrical connection socket is connected to the battery pack.
