Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a connection device for electrical circuit components, and more specifically, it connects a two-terminal electrical circuit component to a relatively large receiving fitting such as a glass tube fuse socket. The present invention relates to a device for fitting and connecting in a manner that allows heat dissipation.

[Prior Art] There are conventional fuse covers for glass tube fuses, etc., as described in, for example, Japanese Utility Model Application Publication No. 53-45442.

This conventional technology includes a fuse cover in which a holder part into which a fuse is fitted and a handle are integrally formed, a holder part into which the fuse fitted into the holder part is inserted, and a terminal. This fuse cover is characterized by comprising a fuse holder attached thereto.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, the fuse is jointed to and removed from its socket via a cover or the like.

Therefore, it is not possible to connect relatively thin leads led out from both sides of other circuit components such as diodes and resistors into relatively large brackets such as glass tube fuse brackets to ensure good heat dissipation. However, since the installation angle of the cover cannot be rotated around the axis of the fuse, a large current may flow the moment the lead or fuse of an electrical component straddles the bracket. You have to turn it off before replacing it,
There was a problem in that turning this main switch on and off was likely to have a great negative effect on other circuits and was dangerous.

In order to eliminate each of the above-mentioned problems, this invention has been developed by rotating and changing the angle of a fixture that temporarily fastens electrical circuit components within the bracket via an operating piece, so that the lead of the above component can be attached to the bracket. The purpose is to connect and separate.

[Means for Solving the Problems] The purpose of this invention described above is to provide a device that connects a pair of leads led out from both ends of a circuit component element to a pair of conductive clamping pieces disposed on an insulating substrate. A circuit component element is housed in a recess cut into a housing part of a column-shaped fixture made of an insulating material, and most of the leads forming the pair are placed in a pair of grooves consecutively provided on both sides of the recess. buried,
Further, an operating piece is provided on the fitting to protrude toward the opening direction of the groove, and the fitting is fitted onto the conductive clamping piece at the mounting portions on both sides of the fitting to rotate the operating piece. This is achieved by allowing the exposed surface of the lead present in the groove of the fixture to be brought into contact with and separated from the inner surface of the conductive clamping piece.

[Function] When connecting the leads of the electric circuit component inserted into the recess of the fixture and the lead of the component partially inserted into the groove into the conductive clamping piece protruding from the board, the operation piece of the fixture should be By rotating the lead by 90 degrees about the axis of the fixture, the exposed surface of the lead can be brought into tight contact with each inner surface of the conductive clamping piece against the elastic force thereof, thereby achieving a conductive connection with good heat dissipation.

Note that when replacing the electric circuit component, the electric circuit component can be removed from the fixture after raising the operating piece by performing the operation opposite to the above.

[Example] Examples will be described with reference to the plane.

First, the basic structure of this invention, as shown in FIGS. 2 and 4, is a pair of conductive clamping pieces 22 on which a pair of leads 13, 13 led out from both ends of a circuit component element 12 are disposed on an insulating substrate 21. , 22, the circuit component element 12 is housed in a recess 18 cut out in the housing part 17 of the almost cylindrical mounting fixture 14 made of an insulating material, as shown in FIG. .

Then, most of the leads 13, 13 forming the pair are buried in a pair of grooves 16, 19, which are continuous on both sides of the recess 18, respectively.

Further, an operating piece 20 is provided on the fixture 14 so as to protrude toward the opening direction of the groove 19, as shown in FIG.

This mounting tool 14 is attached to mounting portions 15, 15 on both sides thereof.
As shown in FIGS. 5a and 5b, after fitting the conductive clamping pieces 22, 22, the operating piece 2
0 as shown in FIGS. 6a and 6b, the exposed surfaces of the leads 13, 13 existing in the grooves 16, 16 of the fixture are exposed to the conductive clamping pieces 22, 22. This is a connecting device for electrical circuit components that can be connected to and separated from the inner surface as shown in FIG. 5c or 6b.

Next, an example of its use will be explained.

First, as shown in FIG. 3, an electric circuit component 11 such as a diode is inserted into a recess 18 of a fixture 14, a circuit component element 12 is inserted into grooves 16 and 19, and leads 13 are inserted into grooves 16 and 19, respectively.

Next, as shown in FIG. 5, with respect to the pair of conductive clamping pieces 22 attached to the substrate 21,
As shown in c, the mounting part 15 of the fixture 14 is pushed in so that the operation piece 20 is substantially perpendicular to the board surface, and the pair of clamping pieces 23 are used to clamp it.

From this state, when the operating piece 20 is further rotated by 90 degrees as shown in FIGS. The electric circuit component 11 is interposed between the conductor 24 and the conducting wire 25, which are clamped and connected to one side of the conductive clamping piece 22, as shown in FIG. 5b.
is connected.

It can be easily removed from the conductive clamping bullet piece 22 by reversing the above-described installation procedure.

Figure 7 shows the state in which this invention is implemented in the fuse unit shown in the conventional example.
is a glass tube fuse, 27, 28 are conductors, 29,
30 is a plug.

[Effects of the invention] Since this invention is configured as described above, it produces the effects described below.

The electrical circuit component 11 inserted into the recess 18 of the fixture 14 and the leads 13, 13 of the component 11 partially inserted into the grooves 16, 19 are connected to the conductive clamping pieces 22, 22 protruding from the board 21. In doing so,
Rotate the operating piece 20 of the fixture 14 by about 90 degrees to the fixture 14.
By rotating the leads 13, 13 about their axes, the conductive clamping pieces 22, 22
It is possible to resist these elastic forces and make a tight contact with each inner surface of the material to make a conductive connection with good heat dissipation.

Therefore, since the relatively thin leads 13, 13 can be used in tight contact with the relatively large conductive clamping pieces 22, 22, the heat dissipation effect is increased, and the electric circuit can be closed by operating the operation piece 20. Since it can be "connected" and "disconnected", it has many advantages, especially in that circuit parts can be easily repaired, replaced, and especially inspected without having to turn on and off the main switch like in the past. .
