An electrical connector (1) includes: a housing (60); at least one contact (20) that is housed in a housing hole (64) including the body (63) of the housing, and extends in a predetermined direction from the housing body (63); and a guide (65) that is disposed contiguously to the housing body (63), and extends from the housing in the predetermined direction. The size of a portion of the guide (65), extending from the housing body (63), is greater than the size of a portion of the contact (20), extending from the housing body (63). The electrical connector (1) is mated with a mating electrical connector and prevents positional deviation between contacts in a pair, which are mated to each other, in a case in which such connectors are connected while being mated to each other.

An electric connector comprises a contact, a base assembly, a pair of first circuit board sections, and a plurality of electric components. The base assembly has a connector face on a first side and an interior side opposite to the connector face. The contact is disposed on the connector face. The pair of first circuit board sections are disposed on the interior side and extend away from the base assembly. The pair of first circuit board sections face each other. At least one electric component is disposed on each of the first circuit board sections.

A connector includes a connector housing (10) with a cavity (15B), into which a terminal fitting (40) is to be inserted. The connector housing (10) is connectable to a mating connector. A retainer insertion opening (30) opens in a side surface of the connector housing (10) and in a direction intersecting an inserting direction of the terminal fitting (40). A retainer (50) can be inserted into the retainer insertion opening to lock the terminal fitting (40). The retainer (50) includes a thin plate (61) extending in an inserting direction of the retainer (50), a convex portion (70) on a lower surface of the thin plate (61) and a groove (71) in the convex portion (70). A projection (25) is provided on a rear part of a locking lance (20) in the cavity (15B) of the connector housing (10) and fits to the groove (71).

An electrical connector assembly for electrically and mechanically connecting a component to a power source is disclosed. The connector assembly includes a male terminal with side walls defining a receiver. The side wall includes a contact arm that extends across an aperture in the side wall. The assembly also includes an internal spring member dimensioned to reside within the receiver of the male terminal. The spring member has at least one spring arm that extends from a base portion. The assembly further includes a female terminal with a receptacle dimensioned to receive both the male terminal and the spring member residing within the receiver of the male connector to define a connected position. In the connected position, the spring arm exerts an outwardly directed biasing force on the contact arm of the male terminal to outwardly displace it into engagement with an inner surface of the receptacle to ensure connectivity.

A connector apparatus for a battery includes: a connector block assembly mounted in a battery case of a battery assembly, and including first and second electrodes facing the interior of the battery case; and a header assembly releasably mounted to the connector block assembly, and including first and second terminals connected to the first and second electrodes, respectively. The header assembly is exposed to the exterior of the battery case and the first and second terminals are electrically connected to terminals of a mating connector, respectively.

A rotatable plug structure for a power adapter includes a carrying base, two conductive terminals and a plug. The carrying base includes a first installation slot, a second installation slot and a channel connected between the two. The conductive terminals are secured onto the first and second installation slots; the conductive terminals include a main body, a wiring portion and a clamping member. The clamping member includes a pair of metal slats bent from the main body and extended to taper toward each other. The plug is rotatably installed on the carrying base and the conductive terminal; the plug includes a pivotal axle, a pair of insertion pins and a conductive connecting end. The plug swings freely about the pivotal axle between a deployed state and a retracted state; thereby, the conductive connecting ends are clamped by the clamping member or disengaged therefrom to overcome the improper contact problem.

In the waterproof connector, a receptacle is provided with a first housing and first contacts, and a plug is provided with a second housing and second contacts. The first housing has a header at one end portion side and a quadrangular shaped waterproof ring mounted to allow close contact with an outer perimeter of the header. The second housing has in its interior a second contact housing chamber into which the header can be introduced, and has a shell which surrounds a periphery of the plurality of second contacts. The waterproof ring has a first pucker, formed with an undulating shape at an outer perimeter of the front portion, and which can closely contact at an inner wall of the shell, and a second pucker, formed with an undulating shape at an outer perimeter of the rear portion, and which can closely contact at an inner wall of a first frame.

An electrical connector assembly includes a board connector and a cable connector. The board connector includes a first seat comprising a base and two first sidewalls commonly defining a mating space, and a pair of first locking portions with locking heads projecting into the mating space, and a plurality of first terminals retained in the first seat and comprising contacting portions projecting into the mating space and leg portions. The cable connector includes a second seat including a pair of second locking portions to engage with the first locking portions and plural second terminals retained in the second seat. The first seat of the board connector further includes a second sidewall unitarily connecting with the base and first sidewalls at a same side and the second sidewall defines a first locking section to engage with a second locking section defined on the cable connector.

An electrical connector assembly for electrically and mechanically connecting a component to a power source is disclosed. The connector assembly includes a male terminal with side walls defining a receiver. The side wall includes a contact arm that extends across an aperture in the side wall. The assembly also includes an internal spring member dimensioned to reside within the receiver of the male terminal. The spring member has at least one spring arm that extends from a base portion. The assembly further includes a female terminal with a receptacle dimensioned to receive both the male terminal and the spring member residing within the receiver of the male connector to define a connected position. In the connected position, the spring arm exerts an outwardly directed biasing force on the contact arm of the male terminal to outwardly displace it into engagement with an inner surface of the receptacle to ensure connectivity.

A terminal is inserted between a first contact and a second contact, formed in the interior of a mating terminal. The terminal includes a plurality of first projections and a second projection. The first projections are disposed on the first surface, and protrude in an orthogonal direction orthogonal to an insertion direction while linearly extending in the insertion direction in which the terminal is inserted into the mating terminal. The second projection is disposed on the second surface, and protrudes in the orthogonal direction. The first projections and the second projection are disposed at positions at which the first projections and the second projection come into contact with the first contact and the second contact, respectively, in a state in which the terminal has been connected to the mating terminal.
