Abstract

PROBLEM TO BE SOLVED: To prevent an increase of stress at a soldering part between a terminal and a circuit board during thermal expansion. SOLUTION: An alignment plate is divided into a plurality of movable holding parts 21A and 21B coupled with each other by a coupling part 23, and coupling positions 23A and 23 with the two movable holding parts 21A and 21B at both ends of the coupling part 23 are made different from each other in height. When a thermal expansion quantity is different between the alignment plate and the circuit board P, while a tilt angle of the coupling part 23 varies, a gap between the adjacent movable holding parts 21A and 21B narrowed or broadened in a plane direction. That is, since excessive strut or tension between the movable holding parts 21A and 21B are avoided, an increase of the stress at a soldering part M of a terminal 15 is prevented.

When the connector housing 2, the alignment plate 4, and the circuit board P thermally expand in a state where the board connector 1 is mounted on the circuit board P, the thermal expansion coefficient of each material is determined. Due to the difference, a force may be exerted between the positioning hole 5 and the connection hole H to cause a relative displacement in a direction perpendicular to the terminal 3 (the surface direction of the alignment plate 4). . However, in the conventional alignment plate 4, since the terminal 3 needs to be positioned with high accuracy, the dimensions are set so that there is no play between the positioning hole 5 and the terminal 3. Therefore, when a force that causes the positioning hole 5 to shift the position with respect to the connection hole H acts, the force is transmitted to the soldering portion M via the terminal 3, and the stress in the soldering portion M increases. Will be. The present invention has been made in view of the above circumstances, and has as its object to prevent an increase in stress at a soldered portion between a terminal and a circuit board.

The board connector C in which the terminals 15 have been aligned and the alignment plate 20 has been mounted on the connector housing 10 in this manner is mounted on the circuit board P. At the time of mounting, first, the tips of the terminals 15 aligned by the alignment plate 20 are inserted into the connection holes H of the circuit board P. At this time, since all the terminals 15 are aligned so as to match the arrangement of the connection holes H, all the terminals 15 are simultaneously and smoothly fitted into the connection holes H. Thereafter, the connector housing 10 is brought into contact with the circuit board P, and the board connector C is fixed at a predetermined position by fixing means (not shown) such as screws. Thus, the work of attaching the board connector C to the circuit board P is completed.

In the mounted state, the three movable holding portions 21A at the center and both ends are attached to the mounting portion (pedestal portion) 22A on the upper surface of the circuit board P, so that the three movable holding portions 21A are suspended from the circuit board P in the vertical direction. (See FIG. 1). The other two movable holding portions 21B are attached to their mounting portions 22B.
Are positioned directly in the vertical direction by directly contacting the upper surface of the circuit board P (see FIG. 2). Well, after installation,
When the ambient temperature rises, each of the movable holding portions 21A and 21B tends to be displaced in the plane direction with respect to the circuit board P due to a difference in thermal expansion coefficient between the circuit board P and the alignment plate 20. However, since the relative displacement of the positioning hole 25 and the connection hole H is regulated by the terminal 15, the adjacent movable holding portions 21A and 21B are spaced from the opposing side surfaces (connection portions 23A and 23B with the connection portion 23). Try to make it narrower or wider. Then, the connecting portion 23 is displaced so as to increase or decrease the inclination angle, so that the gap between the adjacent movable holding portions 21A and 21B approaches or separates in the surface direction of the circuit board P.

That is, when the coefficient of thermal expansion of the alignment plate 20 is larger than that of the circuit board P, the distance between the adjacent movable holding portions 21A and 21B tends to be reduced. In this case, as shown in FIG. As shown in the figure, the inclination of the connecting portion 23 is steep and the movable holding portion 21A at a high position is displaced upward, so that the adjacent movable holding portions 21A, 21A,
The space in the plane direction of 21B is smoothly reduced. Conversely, when the thermal expansion amount of the alignment plate 20 is smaller than the circuit board P, as shown in FIG.
Of the movable holding unit 2 at a high position
1A is displaced downward, and the adjacent movable holding portions 21A,
The interval of 21B increases. As described above, since there is no excessive tension or tension between the adjacent movable holding portions 21A and 21B, the alignment plate
The difference in the amount of thermal expansion between the terminal 15 and the circuit board P is absorbed, so that an increase in stress at the soldered portion of the terminal 15 is prevented.

, The mounting holes 24T of the other four movable holding portions 21A and 21B are elongated holes, so that the connector housing 10 and the alignment plate 20 have different coefficients of thermal expansion. Also, the mounting pin 13 is relatively displaced in the elongated mounting hole 24T.
That is, the relative holding operation of the movable holding portions 21A and 21B is not hindered.

In the present embodiment, the movable holding section 21
Since the plate thickness of A and 21B is substantially the same as the plate thickness of the connecting portion 23, the movable holding portions 21A and 2A are compared with the case where the plate thickness from the upper end to the lower end of the connecting portion 23 is the same.
1B is thin and lightweight. As described above, as the plate thickness is reduced, a difference in height occurs between the adjacent movable holding portions 21A and 21B, and this difference in height is caused by the step-like mounting provided on the movable holding portion 21A at a higher position. Part (pedestal part) 22
A, the upper movable holding portion 21A is reliably restricted from moving vertically in the circuit board P in the same manner as the lower movable holding portion 21B.
