DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a printed circuit board with a connector, in which a printed circuit board to which a connector having a built-in terminal is fixed is sandwiched between respective case members from both sides thereof.

[0002]

2. Description of the Related Art This type of holding structure is disclosed in
As shown in Japanese Patent No. 67072, a connector and a connector board to which the connector is connected are housed in a case, and the opening side of the case is covered with a panel member having an opening for making a connection port of the connector desired. A first rib erected from the periphery of the opening of the member in the vicinity of the connector and a second rib erected from the case at a position facing the edge of the first rib sandwiches the peripheral portion of the connector on the connector board. doing. With the above configuration, it is not necessary to fix the periphery of the connector of the connector board with a screw or the like, and furthermore, even if the mating connector is attached to or detached from the connector, the connector board is unlikely to be bent, and cracking of the soldered portion can be prevented. .

[0003]

However, in the above-mentioned conventional example, the connector peripheral portion of the connector board is sandwiched between the ribs provided on the case and the panel member. When the connector substrate is easily bent toward the panel between the first ribs and the connector terminal is fixed to the connector, a tensile stress to the connector is also applied to the connector terminal. Cracks easily. Further, when a mating connector is attached to the connector board, a pressing force is applied to the connector, and when the space between the second ribs is wide, the connector board is easily bent toward the case side and cracks are easily formed in the soldered portion.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a connector printed board holding structure in which stress is not applied to a soldered portion of the printed board when a mating connector is attached to or detached from a connector fixed to the printed board. The purpose is to provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to a printed circuit board with a connector used for a vehicle instrument. In this embodiment, the case 1 will be described as a first case member, and the cover 2 will be described as a second case member.

FIG. 1 shows a first embodiment of the present invention. For example, a display plate 4 on which scales, characters, numerals and the like corresponding to the meter body 3 are printed on the upper part of the meter body 3 for a tachometer or the like.
Is fixed in place by a screw 5 or the like, provided with a pointer 6 that rotates in accordance with the operation of the instrument body 3, housed in a case 1 having an open front surface, and a case 1 seen from a gap between the display plate 4 and the case 1. A return plate 7 that covers the inside of the case 1 is disposed on the opening side of the case 1. The upper part of the look-back plate 7 is covered with a see-through plate 8. A printed circuit board 9 is provided on the bottom side of the instrument body 3 and is electrically connected to the tachometer. The back surface of the printed circuit board 9 is covered with the cover 2. In addition, the printed circuit board 9, the cover 2, the return plate 7
Are fixed to the case 1 by appropriate means such as screws or hooks (not shown).

On the printed circuit board 9, an electronic component (not shown) for driving the tachometer and a rectangular connector 10 for taking an input signal into the printed circuit board 9 are fixed. The connector 10 has a connection port for connecting to the mating connector 11 facing backward, and one end of the terminal 12 built in the connector 10 on the printed board 9 side is inserted into the printed board 9 and fixed by soldering.

Two first ribs 14 are provided at positions where the first ribs 14 do not protrude from the outline of the connector 10 and come into contact with the printed circuit board 9 while avoiding the soldered portions 13 of the terminals 12.

The cover 2 is provided with an opening 15 facing the connection port of the connector 10, and a second rib 16 is protruded from the vicinity of the opening 15 so as to be provided at the tip of the connector 10 on the connection port side. It is made to abut. 17 is an opening 15
Is a wall that stands upright so as to surround the connector 10.
The wall 17 may not be provided.

With this configuration, when the mating connector 11 is pulled out of the connector 10 fixed to the printed circuit board 9, even if a tensile stress is applied to the connector 10, the tip of the connector 10 is held by the second rib 16. The printed board 9 is hardly bent because it is pressed. Also, when the mating connector 11 is mounted, even if a pressing force is applied to the connector 10, the first rib 1
4, the printed board 9 is hardly bent. Therefore, stress is not easily applied to the soldered portion 13.

In the present embodiment, the first rib 14 is formed so as to be located inside the connector 10 so as not to protrude from the contour of the connector 10. However, if the printed board 9 has a relatively high strength, the first rib 14 is formed. The connector 14 need not be provided so as not to protrude from the contour of the connector 10, and may be provided in the vicinity of the contour capable of supporting the stress, that is, inside or outside close to the outer shape line of the connector 10.

FIG. 2 shows a second embodiment of the present invention, which is the same as the first embodiment except that the cover 2 and the connector 10 are different. The connector 1 is provided on both side walls of the end of the connector 10 on the printed circuit board 9 side.
A boss 18 is provided integrally with the printed circuit board 0, and the printed circuit board 9 and the boss 18 are screwed with screws 5A. Also,
An opening 1 that faces the connection port of the connector 10 in the cover 2
5, the second rib 1 is located near the opening 15.
6 projectingly comes into contact with the head of a boss 18 provided on the connector 10. Reference numeral 17 denotes a wall standing around the opening 15 so as to surround the connector 10. The wall 17 may not be provided.

With this configuration, the same effects as in the first embodiment can be obtained. Further, since the boss 18 provided on the connector 10 is screwed to the printed circuit board 9, when the connector 10 having the built-in terminal 12 is fixed to the printed circuit board 9, the position of the connector 10 and the printed circuit board 9 can be adjusted. Further, the connector 10 does not rise from the printed circuit board 9 and is not soldered. In the present embodiment, a pin is provided on the surface of the boss 18 in contact with the printed circuit board 9, and a through hole is formed in the printed circuit board 9 corresponding to the pin to fit the pin. It may be adjusted.

The present invention is not limited to the above embodiments. For example, the second rib 1 provided on the cover 2
The position 6 is not limited as long as the connector 10 is pressed against the printed circuit board. Further, the first rib 14 and the second rib 16 may be provided in directions orthogonal to each other.

[0019]

The present invention provides a connector, a printed circuit board to which the connector is fixed, a terminal built in the connector, one end of which is pulled out of the connector, inserted into the printed circuit board, and soldered. A first case member disposed on the side to which the connector is attached, and a second case member disposed on the connector side, wherein the first case member is provided on a printed circuit board at a position facing the vicinity of the contour of the connector. The first case member is provided with an opening portion facing the connection port of the connector, and the second case member is provided with a second rib contacting the connector. Since the printed circuit board is sandwiched between the second case member and the second connector, when the mating connector is attached to or detached from the connector fixed to the printed circuit board, the soldered portion of the printed circuit board is removed. Stress retention structure is applied hardly connector with the printed circuit board can be obtained. Furthermore, the first
The effect can be further enhanced by providing the first rib of the case member so as to be positioned within the contour of the connector.
