An electrical contact for use with an electrical connector includes a conducting part and a supporting part wherein the conducting part has a better conduction characteristic than the supporting part while the supporting part has a better resiliency/strength characteristic than the conducting part. The conducting part includes a main body, an upper contacting arm extending upwardly from the main body and a lower contacting arm extending downwardly from the main body. The supporting part includes a secondary body, an upper supporting arm upwardly extending from the secondary body and a lower supporting arm downwardly extend from the secondary body. The main body and the secondary body are engaged together securely. The end of the upper contacting arm and that of the upper supporting arm are coupled together and the end of the lower contacting arm and that of the lower supporting arm are coupled together.

A battery connection device for connecting to a vehicle battery includes a top member, a bottom member having a side wall and a bottom wall. The side wall, top member, and bottom member form a box-like enclosure. The bottom wall includes a through-hole with a circumferential face, an adapter member arranged inside the box-like enclosure extends at least partially through the through-hole for connection with the battery. A dimension of the adapter member is smaller than a dimension of the through-hole to form a gap between an outer face of the adapter member facing the circumferential face and the circumferential face, and flexible connection member connected to the adapter member and to the bottom member and closing the gap between the outer face and the circumferential face. The flexible connection member includes an electromagnetic shield for shielding electromagnetic radiation and a seal for sealing the gap against dust and/or moisture.

It is aimed to provide a connector capable of stably holding terminal fittings in a housing. A connector is provided with a housing and terminal fittings to be held in the housing. The housing includes a plurality of holes arranged in a lateral direction, the terminal fittings being arranged inside the holes, an upper wall surface and a lower wall surface constituting upper and lower regions above and below the plurality of holes arranged in the lateral direction on a rear surface of the housing, and interpolar walls partitioning between the holes adjacent in the lateral direction. Rear surfaces of the interpolar walls are located forward of the upper wall surface and the lower wall surface. The housing includes recesses, the rear surfaces of the interpolar walls serving as back surfaces of the recesses.

It is aimed to reduce friction resistance generated in a resilient contact portion. A shield connector is provided with a dielectric for accommodating an inner conductor, a tubular outer conductor for surrounding the dielectric, a resilient contact portion formed in the outer conductor, and a cut portion formed in the outer conductor and enabling a supporting portion supporting the resilient contact portion, out of the outer conductor, to be resiliently deformed. If the resilient contact portion contacts a mating outer conductor and is resiliently deformed, the supporting portion supporting the resilient contact portion is resiliently deformed by a reaction force from the mating outer conductor. Since a resilient deformation amount of the resilient contact portion is reduced by as much as the supporting portion is resiliently deformed, friction resistance generated in the resilient contact portion is reduced.

In a connector, a contact includes: a first connection portion and a second connection portion that are retained between a first insulator and a second insulator and face each other; and a pressing force receiving portion that makes contact with the second insulator and receives a pressing force from the second insulator to thereby press the first connection portion against the second connection portion. A connection object is sandwiched between the first connection portion and the second connection portion, and at least one of the first connection portion and the second connection portion makes contact with a flexible conductor of the connection object, whereby the contact is electrically connected to the flexible conductor of the connection object.

A card edge connector includes: a housing including a board accommodation space and a connection terminal including a resilient contact piece configured to contact a circuit board inserted into the board accommodation space, the connection terminal being mounted into the housing. The connection terminal is movable between a connection position where the resilient contact piece is in contact with a surface of the circuit board and a retraction position where the resilient contact piece is separated from the circuit board. A first interference preventing portion and a second interference preventing portion are formed between a moving path of the resilient contact piece and the board accommodation space. The first interference preventing portion and the second interference preventing portion restrict the interference of the resilient contact piece and an inserting end part of the circuit board inserted into the board accommodation space in a moving process of the connection terminal.

A terminal of a connector has a receiving portion, a first supporting portion which is resiliently deformable and extends from the receiving portion, a contact portion supported by the first supporting portion, a second supporting portion extending from the contact portion and an abutment portion supported by the second supporting portion. In a connection process of the connector and a mating connector, the abutment portion of the terminal begins to be brought into contact with the receiving portion at a first position on the receiving portion, and it is slid on the receiving portion until the abutment portion reaches a second position. The contact portion is brought into contact with a mating terminal when the connector is connected to the mating connector.

Provided is a spring connector, including a base, a plurality of connector female ends and a grounding ring. The base has a surface. The plurality of connector female ends are disposed on the base and exposed on the surface. End portions exposed on the surface are recessed in the surface. The grounding ring is disposed on the base and exposed on the surface, and correspondingly surrounds at least one of the plurality of connector female ends. An end portion of the grounding ring exposed on the surface is flush with the surface or protrudes from the surface.

An arrangement for electrical contacting of a current connector (3) with a circuit arrangement (1) is provided. The current connector (3) includes at least one contact spring wire (5, 6) with an end contact (5a, 6a), which is configured for spring-loading, and the circuit arrangement (1) includes at least one contact point. The end contact (5a, 6a) and the contact point each form a spring pressure contact, and the end contact (5a, 6a) of the contact spring wire (5, 6) is configured as a bracket with an outer contact surface and at least one cutting edge arranged proximate the contact surface, which is engaged with the contact point.

A system is disclosed. The system may include a modular control unit configured to control power to at least one load device. The modular control unit may include a backplate with a recess that includes a set of backplate electrical contacts. The system may also include a contact element configured to receive the power. The system may also include at least one device control assembly configured to be removably coupled to the backplate. The device control assembly may include a set of device control assembly electrical contacts configured to electrically couple with the set of backplate electrical contacts of the backplate when the at least one device control assembly is coupled to the backplate and configured to electrically decouple from the set of backplate electrical contacts when the at least one device control assembly is decoupled from the backplate.
