Description

[Detailed Description of the Invention] The present invention relates to a connection device for electrical equipment, and its purpose is to withstand vibration and shock, and to prevent the electrical equipment from becoming detached, between sockets that connect electrical equipment and their connection terminals. It provides a connection device.

BACKGROUND ART Recently, electrical equipment has been used which has a thin body and has two rows of connection terminals so as to be suitable for attachment to a printed circuit board.

In order to detachably attach such electrical equipment, a socket is used that has a blade holder that receives the connection terminal and makes a conductive connection, and a connection part that makes a conductive connection to a printed board.

However, in the connection state of electrical equipment and socket,
If the connection terminal and the blade holder become loose, the electrical equipment will come off, so a connecting device is required to prevent the electrical equipment from coming off.

The present invention provides a connection device that is particularly resistant to vibration and shock.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A connecting device for electrical equipment according to the present invention will be described below with reference to the drawings shown as examples.

Figures 1 to 3 show one embodiment of the present invention.
is an electrical device, and on both side walls 2, 2 there is an L-shaped connection terminal formed by a horizontal piece 3a projecting outward from the side wall 2 and a vertical piece 3b extending downward in parallel with the side wall 2. 3゜3・
... is formed protrudingly.

Incidentally, instead of the horizontal piece 3a, a horizontal portion may be provided in which a protruding portion is integrally provided on the side wall 2.

The socket 4 is equipped with blade receivers 5, 5, etc., and the blade receiver 5 has a blade receiver in the insertion opening 6 so as to receive the connection terminal 3 inserted from above. 5a and protrudes downward from the bottom surface of the socket 4.
have.

The socket 4 is provided with external mounting holes or other mounting means so that it can be mounted on a panel such as a control panel.

A pair of protruding walls 7, 7 are provided on each side of the socket 4 where the insertion ports 6, 6, . . . are provided.

This protruding wall 7.7 may be provided asymmetrically as long as it corresponds to the both side walls 2, 2 in the connected state of the electrical device 1.

The pair of protruding walls 7, 7 have engaging portions 7a, 7a and bearing portions 7b.
, 7b are provided, and a space is provided between the protruding walls 7, 7 to accommodate a locking tool 8.

The locking tool 8 includes shaft parts ga, 8a that fit into the bearing parts 7b, 7b, locked parts 8b, 8b that engage with the locking part 7a, and a projection piece 8C. to form.

Reference numeral 9 denotes an elastic release stopper, which is formed integrally with the socket 4 between the protruding walls 7, 7, and prevents the locking device 8 from coming off, thereby making the locking state described later more reliable. .

The connection of electrical equipment according to the present invention is carried out at the connection part 5 of the socket 4.
b, 5b... to the printed board, attach the socket 4, and connect the electrical equipment 1's connection terminal 3゜3...
Insert the vertical piece 3b into the insertion port 6, 6...
is conductively connected to the blade receiving portion 5a.

After that, the upper end of the removal stopper piece 9 is pushed outward of the socket 4, and the inner surface of the upper end and the retaining part 7a of the protruding walls 7, 7,
The shaft portion 8a of the locking device 8 is inserted into the gap formed by the outer surface of the locking device 7a.
.

8a from above, and the shaft portions 8a, 8a are inserted into the protruding wall 7.
, 7 into the bearing portions 7b, 7b.

Next, the locking tool 8 is rotated in the direction of arrow A, and the locked part 8 is
b.

8b is engaged with the retaining parts 7a, 7a of the protruding walls 7, 7.

At this time, the bottom surface of the locking device 8 comes into contact with the upper surface of the outer edge of the socket 4, so the protruding pieces 8C of the locking device 8 are horizontal pieces formed on the connection terminals 3, 3, . . . of the electrical equipment 1, respectively. It stops above the horizontal piece 3a without applying any load to the horizontal piece 3a and is fixed at that position, preventing the electrical equipment 1 from coming off and ensuring a stable connection state.

Then, to remove the electrical device 1, move the locking tool 8 to the arrow A.
It rotates in the opposite direction to release the engagement between the engaging part 7a and the engaged part 8b and remove the protruding piece 8C from above the horizontal piece 3a of the connecting terminals 3, 3, . . . .

According to the connecting device, the secured part 8 provided in the locking device 8
Since the locking tool 8 is positioned between the protruding walls 7 and 7 when the locking members b and 8b are engaged with the retaining parts 7a and 7a provided on the protruding walls 7 and 7, it is protected against vibration and impact. The protruding walls 7, 7 restrict the swinging of the locking tool 8 and stabilize the locked state.

As mentioned above, the present invention provides an L-shaped connection terminal formed by a horizontal piece and a vertical piece on the side wall of an electrical device, connects it to the socket's blade holder, and attaches the electrical device through the socket. At the same time, a pair of protruding walls each having a bearing part and an engaging part are formed on the socket so as to correspond to both side walls of the electric device, and a shaft part and an engaged part are connected between the pair of protruding walls. A locking device is provided, and when the locking device is rotated around a shaft portion of the locking device supported by a bearing portion of the protruding wall, the engaged portion thereof is engaged with the retaining portion of the protruding wall. This is a connecting device for electrical equipment, characterized in that the protruding piece provided on the lock is positioned above the horizontal piece of the connecting terminal of the electrical equipment in the engaged state. , the pair of protruding walls 7, 7 can hold the locking device 8 and prevent the locking device 8 from coming off against vibrations and shocks, thereby preventing the electrical device 1 from coming off from the socket 4, Also, the protruding wall 7
．． 7 and the locking tool 8 are in an engaged state, the protruding piece 8C is positioned above the horizontal piece 3a, and the horizontal piece 3a
There is also no risk that the vertical piece 3b will be deformed.

Furthermore, there is no need to apply a large force to the bearings 7b, 7b of the protruding walls 7, 7 and the shafts 8a, 8a of the locking device 8, and therefore rotation is extremely easy, and the protruding walls 7, Since it is only necessary to provide the locking device 7 and the locking device 8, the structure is simple and can be manufactured economically.
