Description

INTERCONNECTION TERMINAL FIXING STRUCTURE FOR ELECTRONIC SWITCH The present invention relates to an interconnection terminal fixing structure suitable for an electronic device such as a switch, and concerns an improved interconnection terminal fixing structure suitable for an electronic device capable of more stably fixing an interconnection terminal to a main body using manually tightenable bolts.
Figs 1 and 2 show a conventional electronic device such as a switch, which includes a plurality of walls 2 provided at the front and rear sides of a main body 1, respectively.
Three separate and isolated fixing terminals 3 are provided in the side of the switch.
In addition, insertion holes (not shown) are formed at each central portion of the fixing terminals 3, into which a screw is engaged.
The conventional interconnection terminal fixing structure is directed to inserting one end of an interconnection terminal 5 between the upper surface of the fixing terminal 3 and the lower surface of a washer 6 through which the screwed section of the screw 4 can be passed into engagement with the inserting hole of the fixing terminal.
Thereafter, the screw 4 is inserted into the inserting hole of the fixing terminal 3, and the interconnection terminal 5 is fixed to the main body 1 by tightening the screw 4 using a driver 7.
At this time, the lower surface of the washer 6 and the upper surface of the fixing terminal 5 come into tight contact with each other, and the interconnection terminal 5 and the fixing terminal 3 tightly contact each other.
However, since the conventional electronic device is directed to fixing the interconnection terminal to the fixing terminal using screws, if a relatively large capacity device is adopted in the system or if the connection between the interconnection terminal and the fixing terminal becomes loosened due to, for example, an externally applied force such as vibration, arcing between the interconnection terminal and the fixing terminal occurs, which can cause an electric short circuit in the system, whereby peripheral elements can be electrically damaged.
Meanwhile, although a method of using a bolt such as a bolt with an hexagonal head for improving the fixing ability between the interconnection terminal and the fixing terminal was introduced, it is impossible to tighten the bolt using a bolt fixer, such as a box spanner, because the distance between the walls is too narrow to receive the fixer.
Accordingly, it is an object of the present invention to provide an interconnection terminal fixing structure for an electronic device such as a switch, which reduces or overcomes the problems encountered in a conventional interconnection terminal fixing structure for an electronic device.
It is another object of the present invention to provide an improved interconnection terminal fixing structure for an electronic device capable of more stably fixing an interconnection terminal to a main body using manually tightening bolts.
According to the invention there is provided an interconnection terminal fixing structure for an electronic device such as a switch, which includes a bolt insertion groove having a certain width and vertically formed at both sides of the walls in a direction of the interior of the walls, wherein the interconnection terminals are connected to the fixing terminals using a bolt.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a conventional interconnection terminal fixing structure for an electronic device such as a switch.
Fig. 2 is a cross-sectional view showing a conventional interconnection terminal fixing structure for an electronic device such as a switch.
Fig. 3 is a perspective view showing an interconnection terminal fixing structure for an electronic device according to the present invention.
Fig. 4 is a cross-sectional view showing an interconnection terminal fixing structure for an electronic device according to the present invention.
Figs 3 and 4 show an interconnection terminal fixing structure for an electronic device such as a switch according to the present invention.
As shown therein, the structure according to the present invention includes a plurality of walls 12 formed at the front and rear sides of a main body 11.
Three separate and isolated fixing terminals 13 are provided in the side of the switch.
In addition, insertion holes (not shown) are formed at each central portion of the fixing terminals 13, into which a bolt can be engaged.
The interconnection terminal fixing structure for the electronic device as shown in Fig. 3, is directed to engaging the fixing terminal 13 and the interconnection terminal 15 using bolts 18.
Here, preferably, the bolt 18 can include a cross (+) groove 18a or slot formed in its head. That is, with this construction, it is possible manually to tighten the bolt 18 using a driver instead of a bolt fixer tool such as a box spanner, or to use a driver to provide the initial tightening of the bolt and the bolt fixer to provide the final tightening securely to fix the interconnection terminal 15 in place.
In addition, a bolt fixer insertion groove 12a having a predetermined width is formed vertically (in the drawing) in both walls 12 so that the head of the bolt 18 is substantially accommodated therebetween.
That is, the interconnection terminal fixing structure according to the present invention is directed to inserting one open end of the interconnection terminal 15 between the upper surface of the fixing terminal 13 and the lower surface of the washer 16 when the washer 16 is on the screwed section of the bolt 18 immediately above the inserting hole of the fixing terminal 13.
Thereafter, the bolt 18 is screwed into the inserting hole of the fixing terminal 13, and the bolt fixer 19 engages the outer circumferential surface of the head of the bolt along the bolt fixer tool inserting grooves 12a formed in the walls 12, and the bolt 18 is tightened, so that the interconnection terminal 15 is stably connected to the fixing terminal 13.
At this time, since the lower surface of the washer 16 comes into tight contact with the upper surface of the interconnection terminal 15, the contacting surface between the interconnection terminal 15 and the fixing terminal 13 can be maximized, so that a desired engagement therebetween can be obtained.
Meanwhile, when fixing the interconnection terminal 15 to the fixing terminal 13, it is possible to fix it thereto using a driver by inserting the driver into the cross (+) groove 18a formed on the head of the bolt 18. In this case, the engagement of the terminals by the use of the bolt fixer is better than that obtained using a driver.
As described above, the interconnection terminal fixing structure for an electronic device according to the present invention is directed to more stably fixing an interconnection terminal to a main body using manually tightened bolts, so that it is possible to lengthen the life span of the product by preventing arc generation and electrical short circuits in the system.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as described in the accompanying claims.-
