Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a connecting fitting used for connecting parts having boss portions projecting in mutually opposite directions.

"Prior Art" As a conventional connector, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 62-39013.

Although not specifically shown, the conventional connector has an insertion hole into which a boss portion projecting on the component side is inserted on its own flat board, and the connection hole is reverse to the hole edge of the insertion hole. It is configured to raise and form the pawl at a constant inclination angle.

Then, in actual use, by inserting the boss portion on the component side into the insertion hole on the connector side and elastically engaging the tip edge of the check claw on the peripheral surface of the boss portion, the connector Since it can be firmly fixed to the boss portion on the component side, if such a connecting structure is used, the connecting member itself can be connected to the component having the boss portion. It becomes possible to easily connect other parts.

"Problems to be solved by the invention" However, in the conventional connector, the substrate itself is simply formed into a flat plate shape, and the insertion hole having the check claw is formed in the flat plate-like substrate. Therefore, the rising direction of the check claw formed on the edge of the insertion hole is necessarily limited to only the insertion direction of the component boss portion.

Therefore, in the conventional connecting tool, when the boss portion projecting on the component side is inserted into the insertion hole from one direction,
Although there is no problem at all, for example, when trying to connect parts having boss portions projecting in the opposite direction to each other, due to the limitation of the rising direction of the check claw, the boss in the opposite direction is restricted. To connect parts that have parts,
Its structure makes it completely impossible.

For this reason, in this field, the advent of new connecting means capable of easily and surely connecting parts having boss portions projecting in opposite directions to each other is coming to the fore.

"Means for Solving the Problems" The present invention was developed in order to meet such a demand, and provides a connecting metal fitting for connecting parts having boss portions projecting in mutually opposite directions. As a premise, spacer wall pieces are formed on both side edges of the substrate to define a predetermined space between the spacer wall pieces and the substrate, and the boss portions are arranged on the substrate from opposite directions. A configuration is adopted in which an insertion hole that can be inserted and a check claw that is different in direction according to the insertion direction of each boss are formed.

Due to the "action", the connecting fitting of the present invention adopts a structure in which spacer wall pieces are formed on both side edges of the substrate and a space is defined between the both spacer wall pieces and the substrate. Therefore, by using this defined space, it is possible to insert the boss portions into the insertion holes from opposite directions,
It is possible to respectively form two types of check claws having different directions according to the inserting direction of the boss portion.

Therefore, in actual use, insert the boss on one component side into the corresponding insertion hole from one side of the spacer wall,
After engaging the check claw on the boss part, insert the boss part on the other part side from the opposite direction into the corresponding insertion hole and bite the check claw on the boss part as well. Through the metal fittings, the parts having the boss portions projecting in the direction opposite to each other can be connected very easily and reliably.

[Embodiment] Hereinafter, the present invention will be described in detail based on the illustrated embodiments. The connecting fitting according to the first embodiment is integrally formed by punching an elastic metal plate as shown in FIG. Then, the spacer wall pieces 2.2 having a predetermined height are integrally bent and formed on both side edges of the rectangular substrate 1 so that the spacer wall pieces 2.2 and the substrate 1 are both formed. A predetermined space 7 is defined between the lower surfaces.

Then, at both ends of the rectangular substrate 1, circular hole-shaped insertion holes 3, 3 into which a boss portion projecting on one component side is inserted are formed, and the holes of the respective insertion holes 3 are formed. A plurality of check claws 4 which stand up at a predetermined inclination angle upward in the drawing with respect to the edge are integrally formed by bending, and a boss portion projecting to the other component side is formed at the center of the substrate 1. Plural sets of non-return pawls are formed by inserting elongated insertion holes 5 into which the insertion holes 5 are inserted and using the space 7 in the insertion holes 5 in the downward direction in the figure. 6 is integrally formed by bending.

Therefore, in the case of connecting the parts having the boss portions projecting in the direction opposite to each other by using the connecting fitting according to the first embodiment, first, the boss portion B1 on one side of the part P1
B1 is inserted from the spacer wall piece 2 side into the corresponding round hole-shaped insertion hole 3, respectively, and the tip edge of the upward check claw 4 is bited into the peripheral surface of each boss portion B1, so that the connecting metal fitting itself is formed. After fixing to one component P1 side, this time, the other part P2 side boss
Insert B2 into the slot insertion hole 5 from the opposite direction,
A part having boss portions B1 and B2 protruding in opposite directions as shown in FIGS. 2A and 2B when the tip edge of the downward check claw 6 in a pair relationship with the peripheral surface of B1 is also bited. P1 / P2
They will be connected very easily and reliably.

In the space 7 defined between the spacer wall pieces 2 and the substrate 1, it is possible to bend the downward check claw 6 at the edge of the slot-like insertion hole 5. At the same time, the boss B2 on the other component P2 side can be inserted into the insertion hole 5.

In addition, a plurality of sets of check claws 6 are formed at the edge of the slot-shaped insertion hole 5 in an independent state in a pair relationship.
Efficiently absorbs dimensional errors when connecting parts,
Not only is it possible to selectively use the check claw 6 at the optimum position, but even if one of the plurality of check claws 6 is deformed,
It is also possible to use the non-return pawls 6 of other sets in a modified manner.

Next, the connecting metal fittings according to the second embodiment will be described. The connecting metal fittings of the embodiment are also integrally formed by punching an elastic metal plate, and on both side edges of the rectangular substrate 1, This is the same as the first embodiment in that the spacer wall pieces 2 and 2 having a predetermined height dimension are formed and the space 7 is defined between the both spacer wall pieces 2 and 2 and the lower surface of the substrate 1. However, in the second embodiment, as shown in FIG. 3, the spacer wall pieces 2 are formed only on both end sides of the substrate 1 in which the insertion holes 3 are formed, and the central portion of Each of the spacer wall pieces 2A is bent in the opposite direction of the spacer wall piece 2, and a downward check claw 6 facing the elongated insertion hole 5 is fitted to the edge of each spacer wall piece 2A.
