Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to an attachment for mounting equipment, particularly for fixing equipment such as an electromagnetic contactor to a mounting board with screws.

Prior Art In recent years, with the technological development of various parts such as electrical parts and circuit elements, each part in the device has become smaller and the circuits have also been consolidated, and various devices such as electromagnetic contactors and electromagnetic relays have become smaller. It is being

When replacing such a new type of small device with an old, large device, the mounting hole positions for both devices are different, so the mounting screws for the small device must be installed on the mounting board to correspond to the mounting holes. They were forced to do tedious work.

Purpose of the invention The present invention was devised in view of the conventional problems mentioned above, and its purpose is to create a device that can extremely easily attach a new device to the mounting board of an old device without the need to provide new mounting screws. The purpose is to provide mounting attachments.

Structure of the Device In order to achieve the above object, the present invention includes a holding plate portion that comes into contact with a stepped portion provided with a mounting hole of a small device, and a locking claw that is formed protruding from the holding plate portion and locks into the mounting hole. , a screw guide having an arc-shaped cross section for inserting the mounting screw and having an open inner surface and hanging from the base end of the holding plate extending outward from the mounting hole; By locking into the mounting hole of the screw guide, the stepped portion enters a position near the opening of the screw guide, and with the stepped portion being directly pressed and held by the mounting screw via the holding plate, the small device is attached to the large device. It is characterized by being fixed to the threaded part of the board with a screw.

Embodiment FIG. 1 shows a perspective configuration of a device mounting attachment according to the present invention, and FIGS. 6A and B
A front view and a bottom view are shown. This attachment is configured to be engaged with and mounted on a stepped portion 14 provided with a mounting hole 12 of the small device 10 shown in FIG.

That is, the attachment is attached to the stepped portion 14.
a retaining plate portion 16 that abuts on the retaining plate portion 16; a locking pawl 18 formed protruding from approximately the center of the retaining plate portion 16; and a locking claw 18 that is hung from the base end of the retaining plate portion 16 and has an open inner surface for insertion of a mounting screw. Screw guide 20 with an arc-shaped cross section
Further, side walls 22 are provided on both sides of the screw guide 20 and are connected to the retaining plate portion 16.

Therefore, by inserting and locking the locking pawl 18 of the attachment into the mounting hole 12 of the mounting step 14, as shown in FIG. It becomes possible to attach an attachment to 10.

In this case, in order to smoothly insert and lock the locking pawl 18 into the mounting hole 12, in this embodiment, the locking pawl 18 is formed into a split shape, which allows the locking pawl to be elastically deformed. This action allows the locking pawl 18 to be smoothly inserted into the mounting hole 12. Also, a locking claw 18 locked in the mounting hole 12
In this embodiment, the lower end of the locking pawl 18 is formed into a helmet shape, and the mounting hole 12 is formed into a stepped hole as shown in FIG. The helmet-shaped collar 24 is the mounting hole 1.
As a result of being locked to the step portion 25 of No. 2, natural detachment of the locking pawl 18 is prevented.

In this embodiment, side walls 22 are formed on both sides of the screw guide 20 to be connected to the holding plate part 16, and reinforcement against holding deformation of the holding plate part 16 is performed.

A reinforcing rib 26 is formed on the inner surface of the side wall 22, and an engaging groove 30 shown in FIG. By engaging the reinforcing ribs 26, the reinforcing ribs 26 perform both the functions of locating the attachment and guiding the attachment during insertion, thereby making it possible to securely attach the attachment and maintain its position. .

Further, the reinforcing rib 26 is used to form the side wall 2 when the attachment is formed by injection molding or molding.
It plays the role of effectively preventing the thermal deformation described in No. 2, thereby making it possible to prevent molding defects and the like from occurring.

In this embodiment, the small device 10 is fixed to a mounting board (not shown) by inserting a mounting screw 32 into the screw guide 20 and tightening the screw 32 to a threaded portion of the mounting board.

In this case, in the present invention, the inner surface of the screw guide 20 is configured to be open, so that the stepped end surface of the small device 10 is shown in FIG. 5 based on the A-A cross section in FIG. 6B. Like screw guide 20
This allows the stepped portion 14 to overlap the lower surface of the head of the mounting screw 32 or the washer 34 via the holding plate portion 16. Therefore, as the stepped portion 14 is directly pressed by the mounting screw 32 via the holding plate portion 16, the small device 10 can be securely fixed to the mounting board.

As mentioned above, the small device 10 is held by the attachment and fixed to the mounting board,
By installing an attachment on the stepped portion 14 of the small device 10, the screw guide 20 is projected outward beyond the mounting hole 12, and this screw guide functions as the mounting hole. Therefore, this embodiment has the same effect as if the pitch between the two mounting holes of the small device 10 was substantially expanded by attaching the attachment, and as a result, the mounting board has no screws for the small device. It is now possible to directly fix the screws to the mounting threads of older large equipment without the need to form a separate part, making it extremely easy to install small equipment without the need for the troublesome work previously mentioned. It becomes possible.

Effects of the invention As explained above, according to the invention, it is possible to easily attach small devices to the mounting board for large devices, and it is extremely easy to replace old devices with new ones. becomes.
