Description of the Related Art Car plugs have conventionally been used as power connections for, for example, cassette recorders by being inserted into cigarette lighter sockets, which are the power sources of automobiles. In this car plug, the electrical connection of the positive terminal at the tip is made by pulling out the positive lead wire from the rear lug, and the electrical connection of the negative side spring plate is made by pulling out the negative lead wire directly from the rear. For this reason, although the two lead wires are insulated, there is a drawback in that short circuits are likely to occur due to structural defects in the plug. Furthermore, since conventional car plugs are made of a separate material from the fuse,
A fuse had to be installed separately.

本考案は上記欠点を解消するもので、その目的

ある。 The present invention is intended to eliminate the above-mentioned drawbacks, and its purpose is to compensate for the deficiencies in the structure and perfect the insulation.

ヒユーズを固定している。 As shown in FIG. 1, a support 1 made of an insulating material has a housing hole 1a provided therein, and a fuse 2 is housed in this housing hole. The rear end of the fuse 2 is in contact with a rivet 3, which is a stator, which is fixed through the bottom of the support 1. The support 1 has a U-shaped spring plate 4 extending over its bottom.
The legs of this spring plate form contact portions 4a, 4a which extend forward (to the left in FIG. 1) along the guide grooves 1b, 1b and curve outward at their tips. , each contact portion projects outward from the support and constitutes a negative input terminal. Both sides of the spring plate 4 are securely held by a knob 5 and a cap 6, which are screwed onto both front and rear ends of the support 1, respectively. A positive terminal 7 is fitted into the center of the cap 6, and projects toward the front of the cap, and is prevented from coming off by a collar 7a. A spring 8 is stretched between the rear end of the positive terminal 7 and the tip of the fuse 2, and its spring force fixes the positive terminal and the fuse.

ている。 As shown in FIGS. 1 and 2, one end of the lug 10 is fixed by a rivet 3 within a recess 9 provided at the bottom rear end of the support 1. The lug 10 has a curved portion 10a formed by bending the lower side of the spring plate in a detour so as to move away from the spring plate 4, and further has clamping pieces 11, 11 provided at the tip thereof. Each clamping piece 11,1
1 is bent inward to firmly hold lead wires 12 and 13. One lead wire 12 has a lug 10
By connecting to the curved portion 10a of the positive terminal 7, it is electrically connected to the positive terminal 7 via the rivet 3, the fuse 2, and the spring 8. The other lead wire 13 is connected to the spring plate 4 constituting a negative input terminal. In addition, both lead wires 12, 1
3 is pulled out from the pull-out hole 5a of the knob 5.

は大きい。 As described above, according to the car plug of the present invention, since the fuse itself is already stored, there is no need to separately install a fuse on the vehicle body, and the overall structure can be compact. Since the positive lead wire is pulled out to the lug that bypasses this spring plate, contact between the two lead wires can be prevented. Since both lead wires can be stably supported by the holding pieces of the lug, play in the lead wires can be prevented when the car plug is inserted or removed. Therefore, short circuits of the lead wires can be prevented and insulation can be perfected, which has a great practical effect.
