A housing for an electrical connecting terminal comprises a body defining a cavity for accommodating the connecting terminal, and a latch member located in the cavity. The latch member extends from a bottom surface of the cavity toward a top surface of the cavity and includes an opening located proximate the bottom surface of the cavity and a locking portion for locking the connecting terminal within the body.

A contact carrier retains a crimp contact inserted therein at a central collar of the crimp contact in a particularly stable manner and at the same time absorb the highest possible plugging forces. The contact carrier has an insulating body and a retaining plate, which can be mounted thereon on the connection side. Furthermore, the contact carrier has at least one detent element, which, in the unassembled state, can assumed both a position locking the plug contact and a position releasing the plug contact. The detent element is part of the insulating body. The retaining plate also has at least one blocking element, which, in the assembled state, fixes the detent element in the position thereof locking the plug contact and thus prevents the transition of the detent element from the locking position into the releasing position.

A terminal includes: a terminal main body having an electrical conductivity, and including a contact portion; and an insulation member which includes a terminal holding portion which is arranged on a rear end side of the contact portion and held in the housing. The terminal holding portion includes a rotation prevention portion which is engaged with a locking portion formed in the housing to prevent rotation of the terminal in the housing.

A single piece electrical connector having a housing with a mating face, a wire receiving face, and housing side walls. Terminal receiving cavities extend from the mating face to the wire receiving face. The terminal receiving cavities have cavity side walls. Resilient securing arms are provided in the terminal receiving cavities. The resilient securing arms have fixed portions which extend from and are integrally attached to base members which extend from and are integrally attached to the cavity side walls of the terminal receiving cavities. The resilient securing arms are made from the same material and in the same manufacturing process that forms the housing. The fixed ends are spaced from the cavity side walls by gaps. The gaps between the resilient securing arms and the cavity side walls facilitate the cleaning or removal of excess material formed during the manufacturing process of the electrical connector.

A connector assembly includes a connector housing that defines a terminal cavity. A terminal lock is adapted to retain an electric terminal in the terminal cavity in an installed position. The terminal lock includes a lock arm that extends from the connector housing and a lock tab that extends from the lock arm into the terminal cavity. The terminal lock includes a raised ridge on an outer end of the lock tab.

A connection terminal for connecting at least one electrical conductor includes: a housing; a first connection space formed in the housing; a second connection space formed in the housing; a first busbar piece arranged in the first connection space; a second busbar piece arranged in the second connection space; a first torsion spring which is arranged in the first connection space and has a clamping limb and a retaining limb; and a second torsion spring which is arranged in the second connection space and has a clamping limb and a retaining limb. The first connection space and the second connection space adjoin one another. The first torsion spring is arranged in the first connection space and the second torsion spring is arranged in the second connection space such that the retaining limb of the first torsion spring is supported by the retaining limb of the second torsion spring.

It is aimed to reliably prevent inverted insertion of a terminal fitting. Oblique insertion restricting portions (27, 28) recessed while extending in a direction intersecting an inserting direction of a terminal fitting (T) into a connector housing (1) and capable of restricting the insertion of a rectangular tube portion (10) by a material of an inner wall of a cavity (4) biting into the oblique insertion restricting portions when the terminal fitting (T) is inserted in an orientation inverted from a proper posture and in an oblique posture into the cavity (4) are provided on corner parts of the rectangular tube portion (10).

A shield terminal (30) includes a dielectric (40) configured to accommodate inner conductors (32) and an outer conductor (43) surrounding the dielectric (40), and is mountable into a selected one of first housing (10) and a second housing (20). A first locking portion (55) and second locking portions (57) are formed on an outer surface of the outer conductor (40). The shield terminal (30) inserted into a first accommodation chamber (13) is retained by a front retainer (17) restricting the resilient deflection of a first locking lance (14) and the first locking portion (55) being to the first locking lance (14). The shield terminal (30) inserted into a second accommodation chamber (21) is retained by the locking of the first locking portion (55) and a second locking lance (22) and the locking of the second locking portions (57) and a side retainer (24).

An electrical connector comprises a plurality of conductive terminals, a housing and a holder. The housing has a plurality of terminal receiving grooves which extend forwardly from a rear end face of the housing and receive the terminals respectively and a locking structure which is formed to a top surface of the housing. The holder is provided to the housing, the holder has a transverse frame portion which extends in a transverse direction, a plurality of positioning arms which obliquely extend downwardly and forwardly from the frame portion and are respectively inserted into the grooves, and a lock plate portion which extends forwardly from a top of the frame portion to above a top surface of the housing and has elasticity, the arms respectively position the terminals along slopes inside the grooves, the lock plate portion has a lock structure which is locked with a locking structure of the housing.
