A surface mount technology (SMT) terminal header is described for providing an electrical connection to a first printed circuit board (PCB). The SMT terminal header includes multiple first electrically conductive connector elements each having a base configured for surface mount attachment to the first PCB, and an insulative housing having multiple cells and a fixation member configured to attach the housing to the first PCB. Each of the multiple cells is configured to at least partially house one of the multiple first electrically conductive connector elements. Each of the first electrically conductive connector elements includes a position assurance member configured to attach the first electrically conductive connector element to at least one of the multiple cells of the insulative housing.

Provided is a terminal fitting and a connector with which the amount of insertion of the terminal fitting into a housing can be easily controlled. A terminal fitting includes: a tubular connection portion (41); a locking protrusion (51) that is provided so as to protrude from an outer circumferential surface side of the tubular connection portion (41), and is configured to be locked to a groove (66) provided in a housing (60); and a contact-stopper protrusion (55) that is provided on the outer circumferential surface side of the tubular connection portion (41) so as to protrude from mating edges (49) that abut against each other in a circumferential direction thereof in the tubular connection portion (41), and is configured to come into contact with the housing (60) and stop in place.

In resin molding, potting to be conducted with a male terminal bonded to a female terminal increases costs and processes. A resin-molded stator includes a coil, a female terminal, a male terminal, and an insulator. The female terminal includes a female terminal connection portion and a spring portion. The male terminal includes a male terminal connection portion, a wire connection portion, and a second surface contact portion. The insulator accommodates the female terminal connection portion, the spring portion, and the male terminal connection portion, and electrically connects the male terminal to the female terminal. The second surface contact portion faces a second surface of the insulator wall.

A terminal fitting 10 is provided with a terminal body portion 11 extending in an axial direction and a plurality of protrusions 20, 30 and 40 projecting in an intersecting direction intersecting the axial direction from the terminal body portion 11. The plurality of protrusions 20, 30 and 40 are arranged side by side in the axial direction and each protrusion has a top surface 21, 31, 41 along the axial direction, a front surface 22, 32, 42 inclined toward a front side in the axial direction from the top surface 21, 31, 41 and a rear surface 23, 33, 43 inclined toward a rear side in the axial direction from the top surface 21, 31, 41. Projection amounts of the plurality of protrusions 20, 30 and 40 in the intersecting direction are larger for the protrusions more on the rear side in the axial direction.

A micro plug connector has an insulative housing with multiple mounting holes, multiple terminals respectively mounted in the mounting holes, and a shielding shell covering the insulative housing and the terminals. Each terminal has a mounting section mounted in the insulative housing, a welding section protruding backward from a rear end of the mounting section and protruding out of a rear portion of the insulative housing, and an electrical connection section protruding forward from a front end of the mounting section and partially exposed out of a corresponding one of the mounting holes. Each of at least one of the terminals has an anti-bending protrusion abutting against an inner top surface defined in the corresponding one of the mounting holes. The anti-bending protrusion prevents a distal end of the electrical connection section of the terminal from bending up and contacting the shielding shell by accident.

Example implementations involve an electrical connector and a test method of the electrical connector, wherein the electrical conduction condition between a ground member and a ground terminal can be easily confirmed while reliably contacting the ground member and ground terminal. Electrical connector involves a plurality of terminals including two types of terminals, namely, signal terminals and ground terminals; a retaining body, made of an insulating material, that arranges and retains the plurality of terminals in a condition where the signal terminals and ground terminals are intermingled; and a ground member retained by the retaining body on the inward side of the retaining body, in a condition contacting at least two ground terminals; wherein the ground member has a detecting part exposed from the retaining body in order to detect an electrical conduction condition between the ground terminals and the ground member.

An electrical contact includes a base that includes first and second side edges, and a forward edge that extends between the first and second side edges. At least one contact arm extends from the forward edge of the base for making electrical contact with a contact pad. Each of the first and second side edges defines one or more protrusions configured to engage an interior portion of a connector housing for securing the electrical contact within the connector housing. The one or more protrusions on the first side edge are asymmetrically arranged with respect to the one or more protrusions on the second side edge such that respective centers of each of the one or more protrusions on the first side edge are misaligned with respective centers of each of the one or more protrusions on the second side edge.
