An electronic device includes: a substrate having multiple terminal lands and multiple through holes; an electric element including multiple terminals coupled with respective terminal lands and a body on the substrate; and an auxiliary member for assisting fixation between the electric element and the substrate. The auxiliary member includes a base fixed to the body and multiple leg portions extending from the base and inserted into respective corresponding through holes. The leg portions include a pair of locking parts, each having a latch and a spring. The latch is disposed on an insertion end of the leg portion, and is latched around the through hole on the substrate. The spring is deformable when the latch is inserted into the through hole. The pair of locking parts are inserted into two different through holes, respectively.

Electronic device having auxiliary member

An electronic component mounting structure includes a board and an electronic component mounted on a surface of the board. The board includes lands. The electronic component includes a body and terminals extending from the body. Each terminal is electrically connected to a corresponding one of the lands of the board. The terminal has a first terminal portion extending along the surface of the board and a second terminal portion extending toward the surface of the board. Each land includes a land portion electrically soldered to the first terminal portion and a blind hole for receiving the second terminal portion. The first terminal portion is soldered to the land portion in a reflow process under the condition that the second terminal portion is inserted in the blind hole.

Electronic component mounting structure

A mounting structure includes: a surface mounting connector including a housing and a plurality of terminals; a substrate including a plurality of lands, each of which is electrically connected to the terminal with a bonding member; a plurality of support portions for supporting the connector on the substrate; and a plurality of fixing members for positioning the connector on the substrate. Each fixing member is connected to the housing, and contacts a part of the substrate, which is different from a surface portion of the substrate contacting the support portion. Each terminal is positioned on the substrate with a predetermined distance between the terminal and the substrate by the support portions and the fixing members.

Mounting structure of connector and method for mounting connector on substrate

A reinforcing tab for reinforcing connection between a circuit board and a surface-mounted connector includes a fixing wall to be fixed to a housing of the connector and a connecting wall defining a connecting surface on its end to be connected to the circuit board. The connecting wall extends from the fixing wall and includes a bend at least at a part. Further, the connecting wall has a recess on the connecting surface at a position corresponding to the bend.

Reinforcing tab, method of manufacturing the same and structure of connecting connector using the same

A connector mounting structure includes a circuit board, a surface mount connector mounted to the circuit board, and an electronic component. The connector includes a connector body and a plurality of conductive terminals. The connector body has a base portion placed on a front surface of the circuit board and a tube portion. The terminals are disposed in the base portion of the connector body. The tube portion has a first opening portion for partially receiving the circuit board and a second opening portion for communicating with an external device. The electronic component is mounted to a back surface of the circuit board. A space for the electronic component is provided approximately beneath the base portion, between the back surface of the circuit board and the first opening portion of the tube portion.

Connector mounting structure and electronic apparatus having the same

A connector mounting structure includes a circuit board and a male connector. The male connector is surface-mounted to the circuit board and has a housing and terminals. The housing includes a body member and a fixing member fixed to the body member. The fixing member has a tube portion and a protection portion. The tube portion receives a housing of an external female connector. Each terminal has first and second ends. The first end is exposed to a surface of the body member and soldered to the circuit board. The second end is also exposed to the surface of the body member to be electrically connectable to the female connector. The protection portion is placed between the first and second ends in a thickness direction of the circuit board to cover facing area between adjacent first ends.
