Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a blade-type fuse having two contact pieces connected via a fuse member.

<Prior art> Most fuses used in automobiles are blade-type fuses. Each fuse has a fuse box installed near the foot of the driver's seat, and each on-vehicle electrical component such as tail lamp, stop lamp, engine, It is classified and clearly attached for radio, starter, ignition, etc. so that it can be replaced if it is cut off due to overcurrent.

<Problems to be solved by the invention> In the case of installing a retrofit electric component in a car, for example, when a stuffed animal is fixed inside a rear window and a light bulb shaped like its eye is turned on each time the brake is applied. It is necessary to connect the stuffed lead wire to the wiring from the fuse box to the stop lamp.

However, it takes a lot of time to find out the wiring to connect the stuffed toy lead wire from the many wirings, and to check it with a voltage detector, and use a dedicated connector for wiring, and taping after wiring. Troublesome work of insulation is also required. In addition, there is a risk that wiring may be erroneously performed and an excessive current may flow through the retrofitted electrical components to cause broken lines.

<Means for Solving the Problems> Therefore, the present invention has made it possible to connect a lead wire of an electric component to be attached later to a blade type fuse, which is connected via a fuse member housed in an insulating case. A blade-type fuse having two contact pieces projecting from the insulating case, which is electrically connected to one or both of the contact pieces in the insulating case, while a portion extending from the insulating case is an external electric wire. We propose a blade-type fuse that has a conductive member that serves as a connection terminal for connecting to.

<Embodiment> In each of the illustrated embodiments, 10 is a blade-type fuse,
As is well known, it has two contact pieces 11 and 12 which are spaced at a predetermined distance. The upper halves of the two contact pieces 11 and 12 and the fuse member 13 connecting the upper halves are held in a transparent synthetic resin insulating case 14.

In each of the illustrated embodiments, one of the two contact pieces 12 is provided with a connection terminal 15 for connecting an external electric wire. The connection terminal 15 of the embodiment shown in FIG. 1 is formed by providing an upward extension portion on the upper half portion of the contact piece 12 and projecting the upward extension portion 16 from the upper surface of the insulating case 14.

In the embodiment of FIG. 2, the insulated wire 17 whose one end is connected to the upper half of the contact piece 12 is brought out from the upper surface of the insulating case 14, and the connector 18 having the cap tube connected to the core wire is connected to the insulated wire.
It is attached to the other end of 17 to form the connection terminal 15.

Therefore, the contact piece 11 of the blade-type fuse 10 is brought into contact with the battery side terminal piece in the fuse box connected to the battery of the automobile by wiring, and the contact piece 12 is the terminal connecting the wiring to each on-vehicle electrical component. If the rear electrical component is the stop lamp stuffed toy as described above, connect the lead wire of the stuffed animal to the connection terminal 15 provided on the contact piece 12 of the blade-type fuse for the stop lamp, and apply the brake operation. The stuffed toy eyes can be turned on each time.

The contact pieces 11 and 12 of the blade-type fuse have the same shape and size, and either contact piece may be brought into contact with the terminal piece on the battery side in the fuse box and the terminal piece on the electrical component side. If the connection terminal 15 is provided only on the contact piece 12 as described above, there is a directivity that the contact piece 12 must be brought into contact with the terminal piece on the electrical component side.

To eliminate this, provide a connection terminal on both contact pieces 11 and 12, and connect the lead wire of the retrofitted electrical component to the connection terminal provided on the contact piece that contacts the terminal piece on the electrical component side. May be.

<Effect of the invention> Blade type fuses are separated for each on-vehicle electrical component,
Since it is attached explicitly, by providing a connection terminal on the contact piece of this blade type fuse, it is not necessary to find out and check the wiring to connect the lead wire of the post-installed electrical component from among many wirings, and The lead wires can be connected very easily.
