[Problems to be solved by the device]

 By the way, as shown in FIG. 6, the required number of devices such as the terminal block (3) are closely attached to each other, and the fixing metal fittings (4) are attached to both ends of the array, so that In addition to the fixing means for preventing the rail (1) from moving in the longitudinal direction, the device to be mounted may be mounted on the rail (1) at a predetermined interval. In such a case, each device may be fixed by the same means as shown in FIG. 6 by interposing a spacer in the gap between each device, but since the number of spacers used increases as the gap increases, the number of spacers used in FIG. As shown in (), the devices to be mounted (6) are individually fixed by attaching the fixing metal fittings (4) on both sides thereof.

However, the fixing stopper (4) has a complicated structure as compared with the function of simply fixing to the rail (1). That is, as shown in FIG. 8, the pair of claw portions (4b) and (4c) of the mounting body (4a) are engaged with the flange portion (1b) and inserted into the rail (1), and the pressing body (4d) is inserted. ), The fixing screw (4e) that is rotatably inserted in the retaining state is tightened and screwed into the screw hole (4f) of the mounting body (4a). 4g) and (4h) push both sides of the mounting body (4a) so that they spread out, and as a result, both claws (4b) and (4c) bend inward and grip the rail (1). It sticks in the state.

As described above, the fixing metal fitting (4), which has a relatively complicated structure and requires tightening work of the fixing screw (4e) at the time of attachment, is attached to a required number of devices in a close contact state as shown in FIG. At least two are required even when fixing with, and when fixing the devices (6) individually as shown in Fig. 7 (a), more fixing metal fittings (4) are required, so that amount is enough. The cost increases and the assembly time increases.

Therefore, the present invention provides a device mounting rail that can position a device to be mounted without using a fixing metal fitting and a device to be mounted without using a fixing stopper by using the device mounting rail. It is a technical subject to provide a device mounting structure that can be fixed.

[0009]

[Means for Solving the Problems]

 The present invention has a device mounting rail configured as follows as a technical means for achieving the above-mentioned problems. That is, in a device mounting rail in which a flange portion is integrally extended outward from both ends of a base portion having a substantially U-shaped cross-section in the lateral direction, the width of each of the flange portions is shortened. Direction notches are arranged at equal intervals in the longitudinal direction, and bendable locking pieces are formed between each two adjacent notches.

In addition, in the device mounting structure using the device mounting rail described above, a specific locking piece in the device mounting rail is bent so that a device to be mounted has a flange portion of the device mounting rail. A movable side claw part that is pressed and moved in the counter-biasing direction by the flange part by being pressed and then is held by the one surface of the device by the restoring force so as to be sandwiched by the flange part, and is integrally formed with the device. And a fixed side claw part that engages so as to sandwich the flange part with the one surface, and at least one fixed side or movable side claw part is provided at an interval substantially equal to the width of the locking piece. A pair of claw pieces are formed side by side to form a bifurcated shape, and the specific locking piece is positioned between the pair of claw pieces of the bifurcated claw portion so that the mounted device is for mounting the device. It is configured to be mounted on the rail. And are characterized.

[0011]

[Action]

 In this equipment mounting rail, the locking pieces are arranged at equal intervals in the longitudinal direction with the notches on the flange, so it is of the type that is attached to the rail by inserting it into the flange from the end. For example, when arranging and fixing a required number of devices such as terminal blocks in a close contact state, the locking piece at the fixed position of the device placed on one end side of the device mounting rail is bent with a tool such as pliers. Then, when each device is inserted from the other end side of the rail, the bent locking pieces prevent the devices from moving toward one end, thereby positioning each device. Then, after a required number of devices are fitted and brought into close contact with each other, the locking pieces adjacent to the claws of the devices on the other end side are bent, so that each device can be fixed without using a fixing metal fitting.

[0012] Furthermore, in the case of individually fixing, for example, socket devices of a type that has fixed side claws and movable side claws on the rail mounting surface and can be attached by one-touch operation, the fixed side or movable side Since at least one of the claws has a bifurcated shape in which a pair of claws are juxtaposed at intervals substantially equal to the width of the locking piece, bend the locking piece at the position where the bifurcated claw should be fixed. When the fixed side claw is engaged with the flange and then the movable side claw is pressed against the flange, the bent locking piece is placed between the pair of bifurcated claws. Since it prevents the equipment from moving in the longitudinal direction on the rail, the equipment can be fixed independently without using any fixing fasteners.

[0013]

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. 1 (a) and 1 (b) are a plan view and a sectional side view of a device mounting state according to an embodiment of a device mounting rail (10) of the present invention. This rail (10) has an existing flange part (10b) integrally extending in a perpendicular direction from both ends of a base part (10a) having a substantially U-shaped cross section in the lateral direction, that is, the width direction. It has the same external shape as the rail, and the difference from the existing rail is that the notches (10c) in the lateral direction are formed on both flanges (10b) at equal intervals in the longitudinal direction and are adjacent to each other. It has a configuration in which a bendable locking piece (10d) is formed between each of the two notches (10c).

In this equipment mounting rail (10), locking pieces (10d) are arranged in the flange portion (10b) with notches (10c) at equal intervals in the longitudinal direction. As shown in b), like the terminal block (3) provided with the terminal screws (3c) and (3d), engage the claws (3a) and (3b) from the end of the flange (10b). When a required number of devices of the type that are inserted and attached in the combined state are arranged and fixed in a close contact state, as shown in the figure, the terminal block (1) on the device mounting rail (10) The specific locking piece (10e) on at least one side corresponding to the fixing point of 3) is bent with a tool such as pliers. Then, when each terminal block (3) is inserted from the other end side of the rail (10), one claw of the terminal block (3) on the one end side first inserted as shown in FIG. The portion (3b) abuts on the bent specific locking piece (10e) to prevent the terminal block (3) from moving toward one end, thereby positioning each terminal block (3). Then, after a required number of terminal blocks (3) are fitted and brought into close contact with each other, the locking is provided adjacent to the claw portions (3a), (3b) of the terminal block (3) at the other end that is finally fitted. By bending the piece (10d), each terminal block (3) can be fixed without using an existing fixing metal fitting. If the locking pieces (10d) on both sides facing each other are bent together, the positioning can be performed more firmly.

Next, a mounting structure for individually mounting a device such as a socket, which is equipped with a pair of fixed and movable claws using the device mounting rail (10) and can be mounted by one-touch operation, is shown in FIG. It will be described with reference to FIGS. As shown in FIG. 2 which is a bottom view in which a part of the equipment mounting rail (10) is broken, the socket (11) is integrally formed from the side with the upward concave surface (11a) formed on the lower surface. A fixed side claw portion (12) protrudingly engaged with the flange portion (10b) together with the concave surface (11a), and a spring (14) which is held inwardly by a spring (14) so as to be movable in the arrow direction. Like the existing socket, the movable side claw portion (13), which is biased and has a taper formed on the lower surface of the tip end, is provided oppositely, but these claw portions (12), (13) Is formed into a bifurcated shape in which a pair of claw pieces (12a), (12b), (13a), and (13b) are juxtaposed at intervals substantially equal to the width of the locking piece (10d).

Then, after bending the two facing locking pieces (10e) of the flange portion (10b) of the rail (10) where the socket (11) is to be fixed, the fixed side claw portion (12) is attached. As shown in FIG. 4, after positioning so that the specific locking piece (10e) bent between the pair of claw pieces (12a) and (12b) is positioned and engaged with the flange portion (10b), When the movable side claw portion (13) is attached to the flange portion (10b) by a usual means, a specific engagement member bent between the pair of claw pieces (13a) and (13b) of the movable side claw portion (13) is attached. A stop (10e) is located. Therefore, the claw pieces (12a), (12b), (13a), and (13b) come into contact with the specific locking pieces (10e) from both sides, so that the rails (10) of the socket (11) move in the longitudinal direction. Since the movement of the socket (11) is prevented, the socket (11) can be independently fixed without using any existing fixing metal fittings.

Not limited to the above-mentioned embodiment, a single socket (11) may be formed even if only one of the fixed side or movable side claws (12) and (13) has a bifurcated shape with a pair of claw pieces. It is possible to obtain a sufficient function of fixing the.

[Effect of the device]

 As described above, according to the equipment mounting rail of the present invention, since the locking pieces are arranged at equal intervals in the longitudinal direction with the notches interposed in the flange portion, the rail mounting portion is fitted from the end portion. When fixing the required number of devices of the type that can be attached to the rail by inserting them in a close contact state, fix the bent locking pieces by bending the locking pieces at the prescribed locations on the device mounting rail. Since each piece can prevent the rails of each device from moving in the longitudinal direction, each device can be fixed without using a fixing metal fitting, and the assembly cost and the assembly time can be reduced. Moreover, there is an advantage that an unused locking piece can be used as a fixing means by attaching the faston receptacle to the ground of the device.

Further, according to the device mounting structure using the device mounting rail of the present invention, in the device of the type having the fixed side claw portion and the movable side claw portion on the mounting surface to the rail, the fixed side or movable side is provided. Since at least one of the claws on the side has a bifurcated shape in which a pair of pawls are juxtaposed at intervals substantially equal to the width of the locking piece, the locking piece at the position where the bifurcated claw should be fixed is After bending, engage the fixed side claw part with the flange part and then press the movable side claw part against the flange part.When attached by a normal means, the bent locking piece has a pair of claws with a bifurcated claw part. Since it is located between the two sides and also prevents the equipment from moving in the longitudinal direction on the rail, the equipment can be fixed independently without using any fixing fasteners. Therefore, also in this equipment mounting structure, it is possible to reduce the assembly cost and the assembly time.
