Description

[Detailed description of the invention] [Summary] When units are detachably attached in parallel to the side surface of a printed board, the structure is simple and the connector connection is made during the attaching and detaching process.

[Industrial application field]

The present invention relates to a unit mounting structure for printed circuit boards in electronic/communication equipment.

Predetermined circuit functions are configured on a printed board, but when configuring more functions on a printed board of a certain size, or when creating various functional configurations by adding in addition to the basic functions, etc. In this case, another printed circuit board unit is additionally mounted and mounted. Of course, this unit is removable from the main printed board.

[Prior Art] A conventional printed board unit mounting structure is shown in FIG. The figure shows only the main parts. A unit 3 is fixedly attached to the side surface of the main printed board 1 via mounting fittings 2, 2 with screws 4, 5. The printed circuit board 1 and the unit 3 are then circuit-connected by connectors 7 and 8 with cables 6, respectively.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional mounting structure, the unit 3 cannot be attached or detached unless one of the connectors 7 and 8 is attached or detached, and one of the screws 4 and 5 is attached or detached, which is cumbersome to operate and requires a cable attached. Requires connector. In some cases, it may be difficult to attach and remove screws.

[Means for solving problems]

The present invention aims to solve the above-mentioned conventional problems and provide a mounting structure that has a simple configuration and is easy to attach and detach.As a means for that purpose, one end of the unit is received in an inclined state on the side of a printed board. a mounting member that attaches the other end of the unit to the printed board in a state where it is parallel to the printed board from an inclined state, and a connector that is connected to a connector provided on the unit side in the process of changing the other end of the unit from an inclined state to a state parallel to the printed board. This is achieved by providing a unit mounting structure for a printed board, which is characterized in that it is provided with the following.

[Effect]

According to the above means, one end of the unit is supported by fitting, and the other end is attached and fixed by a screw, a fastener, or the like. Since the other end is connected to the connector in the process of changing from the inclined state to the parallel state, it can be attached by a series of flow operations, and no separate operation is required. For removal, the operation is reversed.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows one embodiment of the present invention, as viewed from above.
FIG. 2 is a side view of FIG. 1.

The unit 1 is attached to the side 11 of the main printed board 1.
A U-shaped member 15 having a U-shaped portion 14 for receiving one end 13 of the printed circuit board 1 is fixed to the printed board 1 with rivets 16.

The unit end 1 is on the other end 17 side of the unit 12.
A mounting member 18 for attaching 7 is attached to the printed board 1 with rivets 1.
It is fixed at 9.

As is clear from FIG. 2, the U-shaped member 15 has tongues 20 fixed to the printed board 1 at both ends, a support tongue 21 for the unit 12 on the inside, and a tongue 21 for securing the unit 12 in the center. Each of the tongues 22 is bent, and the length of the locking tongue 22 when bent is shorter than that of the support tongue 21 .

As shown in FIG. 2, the attachment member 18 has tabs 23 for fixing to the printed board 1 on both sides, a tab 24 for supporting the unit 12 on the inside, and a U-shaped portion 25 in the center. It is formed by bending.

Two thumbscrews 29 are fitted into the U-shaped portion 25, the threaded end portion 30 is located inside the U-shaped recess, and a retaining ring 32 is fitted into the neck portion 31 to prevent it from coming off (Figure 1 shows the state before assembly. state). Tip threaded part 30
can be screwed into the screw hole 33 of the unit 12 to attach the unit 12.

A connector 34 is mounted on the printed board 1, and a corresponding connector 35 is provided on the unit 12.

With the above configuration, the attachment and detachment of the unit 12 will now be described. As shown in FIG. 1, the unit 12 is tilted with respect to the printed board 1, and one end 13 is
The U-shaped portion 1 is applied to the supporting tongue piece 21 of the U-shaped member 15.
If you push it to 4, it will get stuck. In this way, it is supported by the locking tongue piece 22 without coming off.

Move the other end 17 in the direction of the arrow so that it is parallel to the printed board 1. The connector 34 fits into the connector 35 inside the unit 12 and is connected to the unit 1.
2 come into contact with and parallel to the support tongue piece 24 of the attachment member 18, and the position is determined.

By connecting the connector in this manner, the unit 12 is fixed in position relative to the printed board 12 in the left-right direction in the plane of the drawing in FIG. The side surface 36 of the unit 12 is provided with support tongues 21, 2.
4 is provided with a distance 37 from the side surface 11 of the printed board, so that it does not come into contact with components or circuit patterns (not shown).

When removing the unit 12, loosen the thumbscrew 29 and it will come off, but it will not come off from the attachment member 18. In this state, when the end portion 17 of the unit 12 is tilted away from the printed board 1, the connector connection is released, so that it can be easily removed from the printed board 1.

In the above embodiment, a thumbscrew is used, but a fastener that can be locked and released with about half a turn may also be used. Further, if a pin is provided protruding from the U-shaped member, and a hole is provided in the unit so that the pins can be engaged with each other to determine the position, the positional relationship will be more stable.

[Effect of idea]

According to the structure of the present invention, the structure is simple, the operability is good, and it is reliable, and the electrical connections are the same, so the practical effects are remarkable.

[Brief explanation of the drawing]

FIG. 1 is a plan view of an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a conventional mounting structure. In the figure, 1 is a printed board, 12 is a unit, 15 is a U-shaped member, 18 is a mounting member, 29 is a thumbscrew, and 34 and 35 are connectors.

Claims (1)

[Scope of utility model registration request] A U-shaped member 15 that receives one end 13 of the unit 12 in an inclined state is attached to the side surface 11 of the printed board 1, and the other end 17 of the unit 12 is attached in a state parallel to the printed board 1 from an inclined state. A unit mounting structure for a printed board, characterized in that a mounting member 18 is provided, and a connector 34 is provided, which connects to a connector 35 provided on the unit side in the process of achieving the above-mentioned parallel state.
