[Detailed description of the invention] (Industrial application field) The invention relates to a support mechanism for a circuit board.

(Prior Art and Problems to be Solved by the Invention) FIG. 8 is a perspective view illustrating a conventional circuit board support mechanism, and schematically shows the circuit board support mechanism. In the figure, reference numeral 1 designates a hole circuit board on which electronic components (not shown) are mounted, which are arranged above and below, and the upper and lower sides 1a of the circuit board l are inserted into the grooves 2a of the friend guide rail 2, and the circuit board The first contact portion 1b is inserted into the plug 3a of the board connector 3. Although not shown in the figure, the guide rail 2 and the board connector 3 are fixed and supported within a frame or a housing using appropriate means.

Moreover, these shapes and layouts are appropriately required. Various means have been devised to improve the mounting rate (ratio of mounting space volume to mounting volume) of the circuit board 1 or to mount circuit boards of different dimensions.

FIGS. 9(a), 9(b) to 12(b) and 12(b) conceptually show a constant pressure surface view and a side view of the supporting machines of each building. The problems associated with the conventional examples shown in each of these figures will be described.

FIG. 9 shows the support mechanism shown in FIG. (not shown).

This support mechanism is a standard one, but since guide rails 2 are provided above and below the circuit board 1, it is necessary to vary the vertical spacing of the guide rails 2 in order to mount multiple circuit boards 1t of different widths. , which worsens the implementation rate. Therefore, it is suitable for mounting circuit boards 1 of the same size.

FIG. 10 shows a companion support mechanism in which the upper side guide rail 2 of the support mechanism shown in FIG. The support strength in the lateral direction is small, resulting in a lack of safety. Particularly in the case of the circuit board 1 having a large area, it may not be practical.

FIG. 11 shows a support mechanism for increasing the mounting rate when a plurality of circuit boards 1 are required and the dimensions of the circuit boards 1, which are the units for inserting circuits, are different in the device configuration. This support machine D
I is a compact circuit board 1', an auxiliary guide rail 2' and an auxiliary board connector 3' mounted on the circuit board 1, and a circuit board 1 mounted on the guide rail 2 and board connector 3. . This support mechanism consists of the circuit board 1 and 1'
However, it has the disadvantage that the implementation rate decreases due to splitting loss. In particular, the mounting rate in the width direction deteriorates.

In addition, in order to increase the mounting rate to the same level as that shown in FIG. 11, the guide rail 2 in FIG. 12 is provided only on one side of the small circuit board 1', and as with the support mechanism shown in FIG. There are drawbacks.

Improving the implementation rate often led to insecure drawbacks.

(Means for Solving the Problems) The present invention was proposed in order to solve the above-mentioned drawbacks, and its purpose is to provide a support mechanism for a circuit board that increases the mounting rate and improves safety. shall be.

To achieve the above object, the present invention provides a support mechanism for a circuit board consisting of a board connector that inserts one side of a circuit board into a guide rail and has a plug to which a contact portion of the circuit board is attached, and the tip of the guide rail. A support rod is rotatably provided on a support rod fixture fixed to a support rod, and a fixed ring is provided at the tip of the support rod. Let's discuss an example. It should be noted that the embodiments are merely illustrative, and it goes without saying that various changes and improvements can be made without departing from the spirit of the invention. This is a companion figure for explanation, where 1 is the circuit board, 2 is the guide rail, and 3 is the board connector, which is the same as the conventional one! It has four functions. 4 is a support rod, 5 is a support rod fixing device, and 6 is a fixed ring in Figure 2 (A).

Further explanation will be given with reference to (b) and e→. The support rod 4 shown in FIG.
Furthermore, the tip portions are bent at approximately right angles to face each other, and the fixed wheel shaft 4
bt-formed. The support rod fixing device 5 shown in FIG.
A hole 5a is provided for AT insertion. The fixed ring 6 shown in FIG. 2 (9) has a hole 6a in the center without a drum-shaped T, through which the fixed wheel shaft 4b provided at the tip of the support w4 is inserted.

Next, the implementation of the circuit board support mechanism of the present invention will be described using FIG. The circuit board 1 is mounted on a rack or a housing, and is inserted into the guide rail 2 and the board connector 3, and the support rod 4 is attached to the guide rail according to the order shown in FIG. 2 fixed to 9 support rod fixtures 5
By rotating it around , the fixed ring 6 rolls to the position shown in FIG. In the state shown in FIG. 3(C), the support rod 4, which is approximately elliptical, extends in a straight line, and due to its springiness, the circuit board 1
T- Clamp and fix.

Next, an example of mounting the small circuit board 1' is shown in FIGS. 4(a) and 4(b), a front view and a side view. Each small circuit board 1
' are respectively attached to the lower guide rail 2 and board connector 3, and each is attached to the support rod 4. The support rod fixing device 5 and the fixed ring 6 press and fix the support rod. This support mechanism can reduce the distance between the auxiliary guide rails 2' and improve the mounting rate compared to the conventional support mechanism for the small circuit board 1' shown in FIG. 11. Also, FIG. In another embodiment, the support rod 4' is connected to the pipe 4'A and the wire 4'B, and the wire 4'
B is telescopically locked in the pipe 4'A by a spring 4'C as shown in FIG. It is a provision. This support rod 4' has a fixed shaft 47a inserted through the hole 5a of the support rod fixture 5 in the same manner as the support rod 4, and the fixed wheel shaft 4'bK has a fixed ring 6 attached thereto through the hole 6a.
Similarly to FIG. 3, the circuit board 1 is fixedly supported.Furthermore, FIG. 6′
It is provided eccentrically with respect to the outer periphery.

This fixed ring 6' is fixed at the center of the fixed ring 6 in the state shown in Fig. 3 (c) when the support rod 4 is moved 9 times in the order shown in Fig. 3 ((), (b) and (c)). is separated from the support rod 4 and stabilized in the sentence position, and the support 44I4 is fixed in a stable state.
