Circuit board assembly, board device, method for assembling circuit board assembly

Abstract

The present invention has an object to provide a circuit board assembly, a board device, and a method for assembling the circuit board assembly that can further increase positional accuracy of a terminal. A contact (25) press-fitted into a holding hole (22) of a housing (21) is held by a press-fitting holding portion (40) formed in the holding hole (22). Friction between a contact press-fitting portion (42) in the press-fitting holding portion (40) and a press-fitted portion (50) of the contact (25) secures the contact (25) to the contact press-fitting portion (42), prevents the contact (25) from dropping off the holding hole (22), and prevents displacement of the press-fitted contact (25) in an extending direction of the holding hole (22) (Z direction) and a direction perpendicular to the holding hole (22) (Y direction and X direction). Further, the contact (25) is press-fitted into the holding hole (22) from a side of a surface (23a) of a contact holding plate (23) where one end (25a) to be inserted into a through hole (31) in a circuit board (30) is located.

Description

technical field [0001] The present invention relates to a circuit board assembly, a board device, and a method for assembling the circuit board assembly. Background technique [0002] It is well known that, when wiring is externally connected to a circuit board used in various control devices, a board-side connector provided on the circuit board is fitted with a wiring-side connector provided on the wiring side. [0003] Such a board-side connector has a housing and a plurality of terminals held by the housing. Then, one end of the terminal is inserted into a through hole formed in the circuit board, and the conductive pattern provided around the through hole and the terminal are soldered to be electrically connected. [0004] Here, there are a vertical type in which the wiring-side connector is fitted to the board-side connector from a direction perpendicular to the surface of the circuit board, and a vertical type in which the wiring-side connector is fitted to the board-...

AI Technical Summary

Problems solved by technology

[0014] However, if the terminal array board 6 is provided, there is a problem that the number of components of the wiring connector 1 increases, and assembly takes time and effort, leading to an increase in cost.

As a result, reliable welding may not be performed in some cases, and the incidence of defective products increases.

[0016] And if there is terminal alignment plate 6, then there is also this problem: after wiring connector 1 is installed to circuit board 3, when spraying anticorrosion agent, terminal alignment plate 6 becomes hindrance, it is difficult to apply anticorrosion agent Apply to the backside area of ​​the terminal alignment board 6

[0017] In addition, if the terminal alignment board 6 is provided, there is also the problem that the dedicated area of ​​the wiring connector 1 on the circuit board 3 increases to the extent of the area of ​​the terminal alignment board 6, which becomes an effective use of the space on the circuit board 3. hindrance

Therefore, in order to hold the first connecting portion, a groove must be formed in the case, and the structure of the case is complicated, and the assembly work of the terminal to the case is also labor-intensive.
