A surface mount connector in which an internal terminal does not extend to a location outside an external terminal is provided. A surface mount connector includes an external terminal that includes a tubular portion that extends in a first direction, an internal terminal that is separated from the external terminal inside the tubular portion when viewed in the first direction, and an insulator that is disposed between the internal terminal and the external terminal and that has a first main surface and a second main surface opposite the first main surface. The insulator inside the tubular portion has a through-hole that extends from the first main surface to the second main surface.

A terminal 20 includes a terminal connection portion 21 connected to a counterpart terminal and a board connection portion 24 connected to a conductive path 13 of a board 11. The board connection portion 24 has a plate shape portion 25 that is a plate shape. The plate shape portion is disposed behind the terminal connection portion 21 and is soldered to the conductive path 13 of the board 11. The board connection portion has a plate-shape first projection walls 28A to 28D that are bent from edge portions of a lateral direction side of the plate shape portion 25 and that project to an opposite side to the board 11 side. The plate shape portion 25 and the first projection walls 28A to 28D have a plating layer 37 that is formed on a plate surface of the plate shape portion and the first projection walls.

A method to manufacture an electrical connection assembly includes: preparing a wiring material (10) that has conductors and an insulation coating, and preparing a connector (CN) including terminals (20) each having an outward projecting portion (24) with a conductor connection surface (27a) and an insulating housing (30). The method proceeds by setting solder on the conductor connection surfaces (27a) and then removing the insulation coating covering parts to be connected from surfaces of the conductors by melting or dissolving the insulation coating. The method also electrically connects the conductors of the parts to be connected to the conductor connection surfaces (27a) by the solder by heating the parts of the respective conductors to be connected together with the solder while holding a state where the conductors of the wiring material (10) are arrayed at intervals from each other in an array direction.

An electrical connector includes a body and a plurality of terminals correspondingly provided on the body. Each terminal includes a base, two embracing arms formed by bending and extending forward from two opposite sides of the base, and a stopping portion formed by extending upward from one of the embracing arms. The two embracing arms jointly clamp a solder to solder the terminal to a circuit board, and the stopping portion is located above the solder to stop the solder from moving upward. The embracing arms clamp the solder, and the stopping portion extends from the embracing arms to stop the solder from moving upward, such that the solder can be well positioned. When the solder is soldered and melted, the embracing arms drive the stopping portion to shrink, such that the embracing arms and the stopping portion jointly squeeze the solder.

According to one embodiment, a printed wiring board includes a wiring board, a connector part, a connection pad provided between the wiring board and the connector part and connected with the connector part with a solder material and a guide groove provided in the wiring board to be continuous to the connection pad, to guide a portion of the solder material from the connection pad.

An imaging module of the invention includes: an image-sensing device that has a light-receiving face, a terminal surface located on an opposite side of the light-receiving face, and a plurality of image-sensing terminals provided on the terminal surface; a support that has a first end disposed on the terminal surface, a second end disposed on an opposite side of the first end, a side face disposed between the first end and the second end, and a guide disposed on the side face so as to correspond to positions of the image-sensing terminals and that is formed of an insulator; a coaxial cable including a conductor disposed on the guide; and solder that electrically connects the conductor to an image-sensing terminal corresponding to the conductor on the guide.

A connector 10 according to the present disclosure comprises a contact 30; and an insulator 20 having an attaching groove 22 on an outer surface into which the contact 30 is inserted and attached, wherein the insulator 20 has a bottom wall 23 formed to be continuous with a bottom surface of the attaching groove 22 in a downward direction; and at least a part of the attaching groove 22 has a wide portion 24 wider in at least one direction than a groove width on the outer surface along a direction parallel to the bottom wall 23.

A functional contactor is provided. The functional contactor according to one embodiment of the present invention includes: a conductive elastic portion configured to be in electrical contact with a conductor of an electronic device and have elasticity; and a functional device including a first electrode electrically connected to a circuit board or the conductor of the electronic device and a second electrode on which the conductive elastic portion is laminated through solder. Here, the second electrode includes a stopper in which no electrode is formed to prevent the solder from being introduced into a periphery of a lamination region on which the conductive elastic portion is laminated.

An electrical spring contact is provided. The electrical spring contact includes a connection portion configured to couple the electrical spring contact to a printed circuit board, a bulge portion, a bend portion having a substantially U-shaped configuration, and an inclined portion extending from the bend portion at an angle relative to a plane that is substantially parallel to the connection portion. The connection portion, the bulge portion, the bend portion, and the inclined portion are formed from a single conductive contact material.

According to one embodiment, a printed wiring board includes a wiring board, a connector part, a connection pad provided between the wiring board and the connector part and connected with the connector part with a solder material and a guide groove provided in the wiring board to be continuous to the connection pad, to guide a portion of the solder material from the connection pad.
