Description

[Detailed Description of the Invention] The present invention relates to a conductor connection device for a motorcycle, and particularly relates to an improvement in the wiring method for electrical components mounted on a motorcycle.

Wiring of electrical components of automobiles or motorcycles,
Most of them were made up of a bundle of conductive wires called a wire harness, and male and female couplers were installed at the tips of the harnesses to make connections at appropriate points. By the way, in the case of motorcycles, the electrical equipment-related operation switches are concentrated in the handlebar grip, and the indicator panel is also often installed in a position directly in front of the handlebar bracket. They were often drawn into the headlight case and connected so that they could not be seen visually. For this reason, the headlight case not only houses the headlight itself, but also this type of wire harness and wire connection members, which inevitably increases its capacity and limits the degree of freedom in design. was. Naturally, if the wire harnesses are concentrated inside the headlight case, not only will it be complicated to route the wires around the steering wheel or steering head when leading the wire harnesses to the rear vehicle body, but it will also be necessary to bundle a lot of wires. As a result, the wire harness becomes thicker, so the wire tends to be partially stretched or subjected to excessive handling due to the turning of the steering wheel, or the cutting of the steering wheel.To avoid this, it was necessary to provide a large amount of deflection. .

The present invention was made to solve these technical problems, and further develops the technical idea of the central coupler, which the applicant has already developed in order to rationalize the wiring for this type of motorcycle. We cleverly take advantage of the advantages of a centralized coupler, which allows wiring harnesses to be concentrated in one place.
By placing this device behind the steering head on the vehicle body, it is possible to avoid increasing the diameter of the wiring around the steering head, eliminate the need for wiring connections inside the headlight case, and make it more compact. This is what I did.

The present invention will now be described in detail with reference to the illustrated embodiment. Fig. 1 is a side view showing the skeleton of the motorcycle of the present invention, with reference numerals 1, 2, wire harness, 3, central coupler, 4, steering head, 5, handlebars, 6, speedometer, 7, headlight, 8, fuel tank, and F, a frame which is a main member constituting the body. The gist of the present invention is that the central coupler 3 is disposed behind the steering head 4 as shown in Fig. 1, and specifically, various mounting methods are used. Prior to the explanation, the central coupler 3 will first be described. This is made of an insulating substrate 1 as shown in Figs. 3 and 4.
A number of coupler plugs 11 are provided on the top surface of the centralized coupler 3, which is composed of a guide frame 12 integral with the base plate 10 and a conductive terminal board 13 disposed inside the guide frame 12. The terminal board 13 is composed of fuse terminals 13a and bus bars 13b which are fitted into each coupler plug 11. The terminal board 13 has an appropriate circuit configuration, so that when a coupler socket 14 from a separate wire harness 2 is fitted into the terminal board 13, the desired circuit connection is made. The back surface of the base plate 10 of the centralized coupler 3 is utilized to provide fuses 15.
Furthermore, a vane-shaped mounting bracket 16 for mounting to a vehicle body is formed integrally with the base plate 10.

A battery 17 is disposed below the seat of the vehicle body 1, and electrical components 18 such as an igniter, a turn signal relay, and a fuse are disposed near the battery 17. Also, 19 is an ignition coil for the rear two cylinders, and 20 is a spark plug.

The central coupler 3 having such a configuration can be attached in various ways, and as shown in FIG. 2, it is first attached to the frame F, which is one of the main components of the motorcycle body. Can be done. The structural member of the frame F to be attached is selected from a tank rail extending rearward from the steering head, etc., and attached as appropriate. Of course, when this frame member uses a round pipe, a flat mounting bracket is separately attached to the frame F for ease of installation. Further, if the frame member uses a square pipe, there is no need to provide such a separate mounting bracket. Further, in order to disperse stress around the steering head, a steel plate is sometimes used together with a pipe as a reinforcing member, but it is of course possible to use the flat portion of such a member as appropriate. Furthermore, the vehicle body to which the central coupler is attached is not necessarily limited to the frame, and may of course be a member fixed to the frame. For example, as shown in Figure 1, it may be installed using the inner recess (frame tunnel) of the fuel tank 8 mounted behind the steering head, or if the fuel tank is not mounted in this area, the fuel tank 8 may be mounted behind the steering head. Of course, it is also possible to use the shroud (dummy tank) provided in the tank and install it inside the shroud.

If the shroud is of a type that can be opened and closed from side to side or upward, it is preferable for maintenance to install it on or near the opening/closing plate of the shroud.

Since the central coupler 3 is attached to the rear of the steering head 4 as described above, as shown in FIG. The conducting wires can be collected separately and connected to the central coupler 3, and on the other hand, the conducting wires can be connected together to at least one of the wire harnesses extending from the central coupler 3 toward the rear or downward side of the vehicle body. Therefore, the wire harness facing the front of the head pipe 4 can be made thinner than at least one of the wire harnesses facing the rear or downward direction of the vehicle body, making the wiring easier. Furthermore, since the rear part of the steering head of the central coupler 3 is generally covered by the fuel tank, shroud, etc., it is less likely to be exposed to rainwater, and the connected state can be maintained for a long time.

As described above, according to the present invention, since the central coupler is provided at the rear of the steering head, the wire harnesses that pass through the steering head, which were conventionally bundled together, can be pulled out separately from the central coupler, for example, the steering wheel switch system. , the indicator lamp system, or the lighting system can be bundled separately and placed so that they pass near the steering head, so the amount of deflection (clearance) required for each wire harness can be reduced. Less is needed. Furthermore, since there is no need to provide sockets at the ends of the wire harness inside the headlight case, the headlight case can be constructed more compactly, increasing the degree of freedom in design settings.
