Description
The present invention relates to an attachment device for push-button switches such as switches used to turn interior lamps on and off in automobiles and so forth.
An example of an attachment device for this type of operating part is described in U.M. Laid-open gazette 4-25125 which was previously proposed by the present applicant.
In this prior art, in addition to providing a hole in an attaching body formed from plastic, a pair of locking ledges are provided protruding from the surface of said attaching body on both sides of this hole in a device that attaches an operating part such as a push-button switch and so forth to an attaching body. In addition, a pair of locking edges, hood and locking wall are formed on the surface of an attaching body near the edge of said hole. Together with the edge of a flange of the operating part inserted between the lower surface of said hood between these locking ledges and the surface of the attaching body being locked by said pair of locking ledges and said locking wall, the operating knob ~
of the operating part is exposed on the opposite surface of the attaching body via said hole.
Although the above-mentioned prior art allows a push-button switch to be attached to the locking ledges and hood of a base with its flange without using a means of fastening, it has the shortcoming of being unable to be applied to push-button switches of the box type which do not have a flange.

In order to eliminate the above-mentioned disadvantages of the prior art, the object of the present invention is to allow the attachment of a push-button switch not having a flange to a plastic base in a single operation without using a means of fastening, and to prevent indiscriminate operation.
The above-mentioned object of the present invention is achieved by inserting an operating piece of a push-button switch into a hole of a base, while allowing play by said operating piece, between a pair of resilient locking pieces integrally provided on a plastic base; and, inserting an insulating plate onto connection terminals provided protruding from the opposing surface on the opposite side of said push-button switch through holes: wherein, projections on both sides of said insulating plate are held by making resilient contact as a result of being pressed onto said resilient locking pieces while deflecting to the outside in opposition to the resiliency of said resilient locking pieces.
Furthermore, guiding beveled surfaces may be provided inclined towards locking ledges.
In addition, a printed circuit board may be used for the insulating plate, the connection terminals of the push-button switch may be inserted into holes provided in conducting land portions of said printed circuit board, and the connection terminals may be soldered to said conducting land portions.
-Since both sides in the direction of pushing operation of the push-button switch attached to the base are supported by being pinched between the surface of the base and the inner surface of insulating plate, the push-button switch itself cannot move indiscriminately in its direction of pushing operation.
In addition, since other unnecessary movement of the push-button switch can be restricted by appropriately inserting its operating piece into a hole of the base 1 and by inserting the connection terminals provided protruding from the opposite side into holes of the insulating plate fixed in position with resilient locking pieces with respect to the base, the push-button switch does not move indiscriminately in any direction.
The invention will be further described by reference to the ~ ;~
accompanying drawings, in which:
Fig. 1 is an exploded perspective view showing an embodiment of the present invention.
Fig. 2 is a longitudinal sectional view showing an embodiment of the present invention.
Fig. 3 is a perspective view showing another embodiment of the present invention.
The following provides an explanation o~ the preferred embodiments of the present invention with reference to the drawings.
Firstly, as shown in Figs. 1 and 2, the basic composition of the present invention consists of inserting operating piece 4a of push-button switch 4 into hole 3 of plastic base 1 between a pair of resilient locking pieces 2 integrally provided on the rear surface of said base 1 along internal pieces la.
As shown in Fig. 1, in the present embodiment, since resilient locking piece 2 forms a box composed of four walls 2 and 2', the resilient efficiency of resilient locking piece 2 is extremely large in comparison with that composed of a pair of resilient locking pieces 2.
Next, connection terminals 5 provided protruding from the opposite surface of operating piece 4a of this push-button switch 4 are inserted through holes 6a of insulating plate 6, spreading open projections 6b provided on both sides of this insulating plate 6 in opposition to the resiliency of said resilient locking pieces 2. Said projections 6b are locked by making resilient contact with locking ledges 2a to hold push-button switch 4 between this insulating plate and base 1, thus composing the attachment device for a push-button switch according to the present invention.
Furthermore, one of the pair of resilient locking pieces 2 may be a fixed piece absent of resiliency having locking edge 2a. In addition, as shown in Fig. 2, guiding beveled surfaces 2b of dimensional difference d may be provided inclined towards the inside in locking ledges 2a of said resilient locking pieces 2, thus facilitating insertion of projections 6b of said insulating plate 6 between locking ledges 2a.
In addition, the bottom of push-button switch 4 may be supported with base projections la.
Moreover, as shown in Fig. 3, by using a printed circuit board for insulating plate 6, inserting connection terminals lS 5 of push-button switch 4 through holes 6a provided in the conducting land portions 6c of said insulating plate 6, and connecting and securing these connection terminals at soldered portions 6d to said conducting land portions ~c, push-button switch 4 and printed circuit board 6 can be simultaneously attached to base 1.
At the time of use, if the operating piece 4a of push-button switch 4 is operated in the same manner as ordinary push-button switches, the electrical continuity between connection terminals 5 can be controlled, thereby allowing the push-button switch to be used as a self-returning or double-push type switch.
The operation of push-button switch 4 can be facilitated by providing cover 4b on operating piece 4a.
- 21 ~ ~2~3 In addition, the guiding, beveled surfaces provided in the locking ledges serve to promote smooth fitting of the projections of the insulating plate.
S The present invention offers the advantages described below as a result of having the composition as explained above.
Since both sides in the direction of pushing operation of push-button switch 4 attached to base 1 are supported by being pinched between the surface of base 1 and the inner surface of insulating plate 6, push-button switch 4 itself cannot move indiscriminately in its direction of pushing operation, thus offexing a first advantage of the present invention of offering reliable and easy operation.
In addition, since other unnecessary movement of push-button switch 4 can be restricted by appropriately inserting its operating piece 4a into hole 3 of base 1 and by inserting connection terminals 5 provided protruding from the opposite side into holes 6a of insulating plate 6 fixed in position with resilient locking pieces 2 with respect to base 1, push-button switch 4 does not move indiscriminately in any direction, thus offering a second advantage of the present invention of, in addition to protecting the operating piece from external force, being able to maintain the prescribed position of the push-button switch for an extended period of time as a result being strongly resistant to external disturbance even when used by installing in moving bodies such as passenger cars and so forth.
