Description

[Detailed explanation of the idea] This invention relates to a connector for panel mounting.

Conventionally, connectors that are attached to a panel are constructed by fixing a bracket part 1a protruding from a connector 1 to a panel 3 with screws 2, as shown in FIG. A holding U-shaped leaf spring 4 is attached to the panel 3 by welding and fixing.

As described above, conventional devices require mounting members such as screws and leaf springs, resulting in a large number of parts and a time-consuming installation process.

This idea involves forming flexible arms and protrusions on the connector housing itself. By simply bending and inserting the arm into the mounting hole of the panel, the restored arms and protrusions will press and hold the connector. It is an object of the present invention to provide a panel mounting connector which can be mounted on a panel and can be mounted with a single touch without requiring a separate mounting member.

Hereinafter, this invention will be explained in detail with reference to examples shown in FIG. 3 and below.

The connector housing 5 shown in FIG. 3 is integrally molded from resin.

Panel mounting portions 6 are formed on both left and right sides of the panel hole insertion side of the connector housing 5 (upper side in FIG. 3).

The panel mounting portion 6 has a protrusion 8 on the inner side (lower side in FIG. 3) of both the front and rear walls 4A, 7B of the outer wall 7 projecting in a U-shape.
A, 8B, and a first arm 9 inclined laterally (to the right in the figure) from the inner side toward the outside (upward in the figure) at the center of the central wall 7C of the outer wall 7; 1 arm 9 and both front and rear walls? A.

7B, the second arm IOA, I which is inclined laterally from the outside to the inside (from the top to the bottom in FIG. 1)
The OB is protruding.

An inwardly directed latch claw 9a is formed at the tip of the first arm 9 so as to face the protrusions 8A and 8B.

The first arm 9 and the second arms IOA and IOB are formed to intersect in an X shape when viewed from the front and rear sides, and the tip of the first arm 9 is outward from the tip of the second arms IOA and IOB. I'm trying to locate it.

Note that the first arm 9 and the second arms IOA and IOB are made of resin and therefore have elasticity.

A mounting hole 12 is pre-drilled in the panel 11 to which the connector is mounted.

Next, the operation of attaching the connector to the panel attaching hole 12 will be explained based on FIG. 5.

First, start from the panel 11 from the end of the panel hole insertion side of the connector.
Insert it into the mounting hole 12 from direction C in Fig. 5.

At the time of insertion, the latch claw 9a at the tip of the first arm 9 is inserted into the mounting hole 1.
However, since the first arm 9 is flexible, when it is inserted from the C direction, the latch claw 9a
While bending inwardly along the outer edge 12a, the slanted surface is inserted into the mounting hole 12 as shown by the chain line in the figure.

When the tip point E of the latch claw 9a passes the inner edge 12b of the mounting hole 12, the first arm 9 is released from the pressure and returns to its original state due to its elasticity, and the point E of the latch claw 9a passes the inner edge 12b of the mounting hole 12. It is hooked and locked in the section.

Further, the outer edge surface F of the first arm 9 is pressed against the inner surface of the mounting hole 12.

On the other hand, as the second arms IOA and IOB are inserted in the C direction, they are also pressed against the outer edge 12a of the mounting hole 12, and are inserted while the inclined outer end surface G surface is bent inward, and the second arms IOA and IOB are inserted at a point on the G surface. must be pressed against the outer edge of the mounting hole.

When point F of the latching claw 9a of the first arm 9 is locked to the periphery of the mounting hole 12, the protrusions 8A and 8B are latched to the outer periphery of the mounting hole 12.

In this way, there are protrusions 8A on the outer surface of the panel around the mounting hole 12,
The connector is attached with the hook 9a of the first arm 9 abutting the inner surface of the panel and holding the panel 11 between the connectors 8B and 8B.

Also, the F surface of the first arm 9 is at the F-P point and the G surface of the second arms IOA and IOB is at the inner edge 12b of the mounting hole 12 at the G-P point.
Since each of them is pressed against the outer edge 12a of the mounting hole 12 at the point P, the mounting can be performed in the vertical direction in the direction H in the figure without any play.

Note that there is a difference in the width 1 of the panel 11, and the protrusion 8A is inserted further from the time when the latch claw 9a is locked.

If it is necessary to bring 8B into contact with the outer surface of the panel, the F surface of the first arm 9 and the G surface of the second arms IOA and IOB will press against the mounting hole 12 even if the latch claw 9a is slightly unlocked. Therefore, it can be installed securely without any play.

When removing the connector from the panel 11, simply push down the D side of the latch claw 9a of the first arm 9 by hand, release the lock, and push it in the J direction opposite to the C direction. can.

In the above embodiment, there is one first arm 9, and the second arm I
Although the number of OA and IOB is two, the number of first arms may be two or more, the number of second arms may be three or more, etc., depending on the size of the connector.

As is clear from the above description, the connector according to the invention includes a flexible first arm provided with a hook on both sides of the panel hole insertion side of the connector housing; Since the panel mounting part is formed by a flexible second arm tilted in the opposite direction and a protrusion that protrudes to face the above-mentioned latching claw and clamps the panel, the panel hole is It can be installed with one touch by simply inserting the insertion side into the panel mounting hole.

Further, since the first arm and the second arm are in pressure contact with the inner and outer edges of the panel mounting hole, the panel can be mounted and held without any play.

In this way, since a separate mounting member is not required, costs can be reduced, and the mounting work is extremely simple and can be completed in a short time.
