A magnetic connector assembly has a female connector with spring-loaded conductive pins slightly protruding inside a recess or cavity in the female connector's body. A corresponding male connector has a protrusion on its body with conductive pins slightly indented into the protrusion's surface. The protrusion on the male connector is sized and shaped to fit into the cavity in the female connector such that the male connector's pins engage the pins of the female connector, allowing for electrical communication across the connector assembly. Magnets on the male and female connectors secure them in a correct orientation. A unique shape ensures proper alignment of the pins and prevents the connection of incompatible devices.

An electrical connector for charging has a connector base, a first conductive terminal, a second conductive terminal, and an insulation base. The first conductive terminal is mounted in the connector base and has an upper chamber and a lower chamber. The second conductive terminal is located in and coaxial with the first conductive terminal and is electrically isolated from the first conductive terminal. The insulation base is mounted between the first and the second conductive terminals. An end of the second conductive terminal is located in the upper chamber and another end protrudes out of a bottom of the insulation base. The insulation base has at least one first groove lower than an imaginary datum plan and at least one platform higher than the imaginary datum plane and coaxial with the first groove. By the first groove and the platform, the creepage distance is increased.

The present disclosure relates to a connecting element for electrical connecting two electrical modules arranged in a transmitter housing of a field device, into which transmitter housing the connecting element is insertable, the connecting element including: at least two essentially rod-shaped metal conductor elements, each with two opposing end sections, wherein the conductor elements are arranged in a defined separation relative to one another; and surrounding the conductor elements and electrically insulating them from one another, a multi-membered insulating body including two insulating body end segments of at least a first synthetic material and an insulating body intermediate segment of a second synthetic material different from the first synthetic material, wherein the first synthetic material has a modulus of elasticity greater than a modulus of elasticity of the second synthetic material.

Devices and methods for a sealed electrical connector are described herein. Some embodiments include a spring connecting a first PCB to a second PCB, wherein the spring includes a first end portion in contact with the first PCB, a second end portion in contact with the second PCB, and a middle portion extending between the first end portion and the second end portion, a spacer surrounding the middle portion of the spring, a first seal seated in a first groove of the spacer and in contact with the first PCB, and a second seal seated in a second groove of the spacer and in contact with the second PCB.

A floating connector and an assembly thereof are provided. The floating connector includes: a center conductive pin; an insulating seat which surrounds the center conductive pin; a mating side conductive shell which surrounds an outer periphery of the insulating seat; a movable conductive shell which is movably received in mating side conductive shell; an elastic element which elastically abuts against an upper end of the movable conductive shell; and an inner conductive shell which is interposed between the elastic element and the center conductive pin; the inner conductive shell has a fixing portion and a movable contacting portion, the fixing portion snaps on one of the mating side conductive shell and the movable conductive shell; the movable contacting portion slideably elastically abuts against the other of the mating side conductive shell and the movable conductive shell. In a vibration circumstance, a good electrical connection can be maintained and transmission quality of an electrical signal can also be promoted at the same time, which is particularly applicable to a situation of high frequency signal transmission.

According to a certain embodiment, a pin plunger includes: a first contact member; a second contact member that faces the first contact member and is apart from the first contact member; a spring arranged between the first contact member and the second contact member; and a housing that houses the first contact member, the second contact member, and the spring.
