Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrical equipment such as small switches and pilot lamps that are mounted on a panel and used, and its purpose is to electrical equipment that has been soldered to a printed board 5 or a lead wire. To provide a panel-mounted electric device whose main body can be easily attached to a mounting body attached to a panel.

Conventionally, when an electrical device is mounted on a panel, as shown in FIG. 1, a mounting body 2 is fixed to a main body 1 of the electrical device 10, and the main body 1 and mounting body 2 cannot be removed.

In a conventional structure having such a structure, as shown in FIG. 2, the main body 1 is inserted into a hole formed in panel A from the front side of panel A together with a fixed mounting body 2, and the arm portion 2a of the mounting body 2 is inserted into the hole in panel A. After the terminals 1a and Ia are attached to the panel by pressure contact 15, the terminals 1a and Ia are soldered to the printed board B on the back side of the panel A. In today's electrical equipment for mounting, it is extremely difficult to make solder connections on the back side of panel A, as the back side of panel A has become extremely narrow due to the progress of miniaturization of various electrical devices. The present invention has been made in view of these conventional drawbacks and to improve them.

Embodiments of the panel-mounted electrical equipment of the present invention are shown below in Figures 1 and 2.
This will be explained with reference to FIGS.

In Figures 3 to 4, 1 is the main body of an electrical device such as a switch, 1a is a terminal, Ib is an engaging part consisting of a slope C and a protrusion D, Ic is a support part, ld is an assembly frame, and 2 is a mounting part. body, E
02a is the arm part, 2c is the flange part, 2d is the stepped part, J is the connecting part, A is the panel for installing electrical equipment, B is the terminal of main body 1 This is a printed board to which 1a is connected by soldering. The main body 1 includes a handle for operating the switch, a reversing mechanism, contacts, etc. in an insulating container, and is assembled using an assembly frame 15ld. The arm portion 2a has a cutting piece E and a hole F.
, is more familiar than the nail G. The mounting body 2 consists of a flange portion 2c integrally formed with the arm portion 2a, and the left and right mounting bodies 2, 2
are connected at a connecting part J. Note that the hole F of the arm portion 2a may be provided with two claws G as a notch H as shown in FIG.
The engaging portion 1b may be a recess D as shown in FIG.
As shown in FIG. 4, since the mounting body 2 is provided separately from the main body 1, the mounting of the main body 1 to the panel A is done by using the cut and raised pieces E of the left and right mounting bodies 2, 2. A hole with dimensions slightly narrower than the spacing E is provided in panel A, and when the mounting body 2 is first inserted into the hole in panel A from the front side, the flange portion 2c hits the edge of the hole on the front side of panel A and is locked. Then, due to the springiness of the cut and raised piece E, it springs against the edge of the hole, and the mounting body 2 snaps onto the panel A.

Next, when the main body 1 with the printed board B soldered to the terminal 1a of the main body 1 is inserted between the mounting bodies 2 and 2 from the back side of the panel A, the lower end of the mounting body 2 is guided by the slope C of the protrusion D. It slides smoothly, and the protrusion D fits into the hole F, and the protrusion D is locked by the claw G, and the step part 2d of the mounting body 2 and the support part 1 of the main body 1 are connected.
c comes into contact and the attachment of the main body 1 is completed. Of course, it is also possible to fit the main body 1 and the mounting body 2 in advance from the front side of the panel A, and then insert the main body 1 and the mounting body 2 into the holes of the panel A from the front side. Furthermore, when inserting the main body 1 into the mounting body 2.2, the mounting body 2.2
is pushed from the back side of panel A toward the front side, so in order to prevent the mounting bodies 2 and 2 from coming off, cut and raise the cut and raised piece E slightly diagonally as shown in Figure 4 and place it on the back side edge of the hole in panel A. You can also lock it and write a trigram. Of course, the mounting body 2 can be removed from the panel A by pressing hard. Also, when removing the main body 1 once attached from the mounting bodies 2 and 2, the main body 1 and the mounting bodies 2
, 2, insert a tool such as a screwdriver into the gap between the mounting body 2.
, 2, the protrusion D separates from the claw G and comes off.

FIG. 7 shows another embodiment in which the assembly frames 1d of the main body 1 are opposed to each other and guide grooves 1e are provided on both sides of the main body 1 to form an engaging portion 1b that includes a holding means for the mounting body 2. The dimension Y of the opposing portion of the assembly frame 1d is made narrower than the dimension X of both ends of the mounting body 2, and the dimension of the guide groove 1e is made approximately equal to the thickness of the mounting bodies 2, 2.

The installation is performed by inserting the mounting bodies 2, 2 into the holes in the panel A, and then inserting them into the guide grooves 1e of the main body 1. Insert the lower end of the mounting body 2.2 into 1e while sliding it.

The mounting bodies 2, 2 are pushed outward by the insertion of the main body 1, and the cut and raised pieces E. E presses and snaps onto the edge of the hole in panel A, and the hole F fits into the protrusion D, and the guide grooves 1e and 1e hold the mounting bodies 2, 2, so that the main body A is attached to the mounting body 2, 2 can be securely attached. The guide groove 1e may be formed from a synthetic resin molded product constituting the main body 1, and the hole F has a notch H as shown in FIG. 5, and the engaging portion 1b has a depression D as shown in FIG. ', slope C may be used. Furthermore, the cut-and-raised piece E is made by directly cutting and raising a part of the arm portion 2a as shown in FIGS. 3 and 7.
By integrally forming the mounting body 2, the materials required for the mounting body 2 can be reduced and manufacturing can be done at low cost.

As explained above, the present invention provides an electrical device having engaging parts on both outer sides, a spring-like arm part that is removably engaged with the engaging parts, and springs against the inner peripheral edge of a hole in a panel; The mounting body includes an integrally formed flange portion that engages with the mouth edge of the hole when the arm portion is inserted into the hole in the panel, and the mounting body serves as the main body of the electrical equipment, and the main body of the electrical equipment is The main body of the electric device is large enough to be inserted into the hole, and the main body of the electric device is large enough to be inserted into the hole, and when the electric device is inserted from the side opposite to the side where the flange portion is provided, the Since the joining part is designed to be engaged with the mounting body, the main body 1 and the mounting body 2 can be fitted and locked separately from the front and back of panel A, and the main body 1 and the printed board can be connected to each other from the outside of panel A. B can be soldered and inserted into the panel A from the back side, and can be fitted and locked to the mounting body 2.

Therefore, there is no need to perform soldering work on the narrow back side of panel A, and furthermore, the panel A and the mounting body 2 and the mounting body 2 and the main body 1 are fitted into each other, so that the narrow back side of panel A The installation work on the back side can also be done with one touch, making it an easy-to-install panel mounting device for electrical equipment.
