Description

[Detailed description of the invention] [Field of industrial application] The present invention improves workability by making it easier to assemble parts (including not only single parts but also partially assembled parts). The present invention relates to a structure of a bracket for assembling parts that does not cause looseness after being assembled to a main body.

[Conventional technology]

For example, there is a device shown in FIG. 7 in which a component having brackets at both ends is assembled to a mating body using both brackets.

In the figure, a large relay main body 1, which is a part to be assembled, has a plate-shaped insertion bracket 2 on one side,
A screw fastening bracket 3 is provided on the other side, and a connector 5 for a wire harness 4 for supplying power and signals is provided on the lower surface.

The screw fastening bracket 3 has a bolt insertion hole 6, as shown in FIG.

The relay block base, which is the main body on which the parts are assembled, has a protrusion 8 and a holding member 9 fixed on the mounting surface 7a (see FIGS. 8 and 9), and there is a gap between the protrusion 8 and the holding member 9 and the mounting surface 7a. A space is formed in which the insertion bracket 2 is inserted.

In addition, as shown in FIG. 11, the mounting surface 7a has
The embedded nut 10 is embedded and fixed.

The relay block base 7 is provided with a body mounting foot 11 on the opposite side of the mounting surface 7a.
1 is attached to a wall surface of a vehicle body or the like with bolts or the like to support a relay block base 7.

A relay housing 12 for accommodating a small relay is provided on the upper surface of the relay block base 7, and terminals of a wire harness 13 are electrically connected within the relay housing 12.

The bolt 14 inserted into the bolt insertion hole 6 is screwed into the embedded nut 10 via the washer 15 and the screw fastening bracket 3 to assemble the large relay main body 1 to the mounting surface 7a.

Next, the assembly order of the large relay main body 1 will be explained.

As shown in FIGS. 8 and 9, when the tip of the insertion bracket 2 is inserted between the holding member 9 and the mounting surface 7a, the insertion bracket 2 is inserted between the holding member 9 and the mounting surface 7a. It is loosely fitted between the protrusion 8 and the holding member 9 in the vertical direction.

Next, as shown in FIGS. 10 and 11,
When the bolt 14 is inserted into the washer 15 and the screw fastening bracket 3 and screwed into the embedded nut 10, the large relay main body 1 is assembled to the relay block base 7.

As described above, the assembly of the large relay main body 1 requires two operations: insertion of the insertion bracket 2 and screwing in of the bolt 14, resulting in the following problems.

[Problem that the invention attempts to solve]

(1) Assembly work must be done as easily and efficiently as possible, but tools such as spanners are required to tighten bolts.

(2) It is extremely difficult to assemble the large relay body with one hand; it requires both hands.

(3) As shown in Fig. 9, the holding member 9 and the mounting surface 7
Since a gap c is created in the insertion bracket 2 that is loosely fitted into the space formed between the two parts a, the large relay main body 1 vibrates when the relay block base is mounted on a vehicle body, etc. The mounting bracket may break.

The present invention has been made to address this problem.

[Means for solving problems]

The present invention provides a bracket for assembling a component that is provided at both ends of the component and is assembled to the mounting surface of a mating body. , an engaging portion protruding from the mounting surface, a bent protruding portion at the intermediate portion of one of the brackets, a one-touch engagement piece on the other bracket, and one of the brackets having a one-touch engagement piece for inserting the bracket. When inserted into a space, it is assembled with elastic force to the main body using the protruding part as a fulcrum, and after one bracket is assembled to the main body, the other bracket is attached to the engaging part. It is characterized by a one-touch engagement piece that can be assembled.

[Operation] With the above configuration, when the tip of one bracket is inserted into the space formed between the holding member and the mounting surface of the other body,
A protrusion on one of the brackets creates an elastic force that prevents the component from approaching the mounting surface of the body.

Next, when the other bracket is pressed against the mounting surface of the main body against the above elastic force, the one-touch engagement piece of the other bracket engages with the engagement part, so that
Since the parts are assembled to the main body with one touch and the protrusion presses the mounting surface, there is no looseness between the two assembled parts.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Note that the same parts as in the conventional example are given the same reference numerals.

As shown in the perspective view of Fig. 2, the large relay main body 1 assembled to the relay block base 7 is similar to the conventional example in that it has brackets at both ends, but the structure of the brackets provided at both ends is different. do.

That is, as shown in FIGS. 3 and 4, the insertion bracket 16 provided on the right side is an elastic plate-shaped body having a protrusion 16a in the middle portion that bends and protrudes toward the mating component. When the tip 16b is inserted into the holding member 9 of the relay block base 7 and the large relay main body 1 is pressed against the relay block base 7, the insertion bracket 16 is bent and the tip 1
6b comes into pressure contact with the inner wall surface of the holding member 9 with elastic force, and the protrusion 16a comes into pressure contact with the mounting surface 7a of the relay block base. Force arises.

Although the protrusion 8 is used to prevent the insertion bracket 16 from coming off, it may also be provided integrally with the holding member 9.

Further, as shown in FIGS. 5 and 6, the bracket 17 with an engaging piece provided on the right side of the large relay main body 1 has a hole 18 bored in the middle, and the inner peripheral edge of the hole 18 is located at opposing positions. Slits 19, 19 are provided in the hole 18, and a one-touch engagement piece consisting of two elastic pieces 20, 20 protruding in a truncated conical shape in the opposite direction of the mating part is formed at the inner peripheral edge of the hole 18.

Furthermore, the tip of the bracket 17 with an engaging piece is connected to the first
As shown in the figure, the grip portion 21 is formed by bending.

On the other hand, in the relay block base 7, an embedded bolt 22 is embedded and fixed on the mounting surface 7a at a position opposite to the hole 18 when the large relay main body 1 is assembled, and is engaged with the elastic piece 20 of the one-touch engagement piece. An engaging portion that fits is formed.

Relay block base 7 and large relay body 1
The other structure and attached parts are the same as those of the conventional example.

Both components configured as described above are assembled in the following manner.

As shown by the dashed line in FIG. 1, with the large relay main body 1 tilted with respect to the mounting surface 7a of the relay block base 7, grip the grip part 21 with one hand and hold the tip of the insertion bracket 16. It is inserted between the member 9 and the mounting surface 7a.

Next, when the gripping portion 21 is pressed in the direction of the arrow 23, the protruding portion 16 of the insertion bracket 16 is pressed.
a comes into contact with the mounting surface 7a, and further, the tip 16b contacts the inner wall surface of the holding member 9 with the protrusion 16a as a fulcrum, and the gripping portion 21 is given elasticity in the direction opposite to the arrow 23. When the gripping part 21 is pressed in the direction of the arrow 23 against its elasticity, the insertion bracket 16 is elastically deformed, the protruding part 16a is pressed against the mounting surface, and the tip 16b is pressed against the inner wall surface of the holding member 9. do.

Then, as shown in FIG. 6, the tip of the elastic piece 20 of the one-touch engagement piece hits the thread of the embedded bolt 22 and passes through the thread while being bent, and the bracket with engagement piece 17 is attached. The large relay main body 1 is assembled to the relay block base 7 by contacting the surface 7a.

Since the elastic piece 20 of the one-touch engagement piece is engaged with the embedded bolt 22, the large relay main body 1 will not come off from the relay block base 7 even if an external force is applied to the large relay main body 1.

In addition, since the insertion bracket 16 is fitted to the relay block base 7 with elastic deformation, there will be no play between the two assembled parts.

As explained above, the assembly of the large relay main body 1 is accomplished by a one-touch operation of gripping the gripping part 21 with one hand, inserting the insertion bracket 16 into the holding member 9, and pressing the gripping part 21 against the relay block base 7. Since all of the installation and fastening of the large relay body 1 is completed, the assembly work becomes extremely simple.

In addition, although the large relay main body was explained in the example, parts with brackets at both ends (single item,
It can be widely applied to sub-assembled parts).

In addition, the embedded bolt 22 is used as the engagement part on the main body side, and the elastic piece 20 of the one-touch engagement piece is shaped like a truncated cone. It may be in the shape of

〔effect〕

The present invention has the following effects.

(1) Since the parts to be assembled can be grasped with one hand and the attachment and fastening to the mating parts completed with one-touch operation, the assembly work can be completed in an extremely short time and work efficiency is greatly improved.

(2) Tools such as spanners that were necessary for assembly are no longer required, and the worker does not have to carry tools or have to take the trouble of taking tools.

(3) Since the assembled parts do not have the rattling like conventional products, there is no rattling even if the product is installed in something that generates vibrations, such as a vehicle, and therefore damage to the assembled parts is prevented. This also prevents noise caused by vibration.
