Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure for a vehicle speaker.

[0002]

2. Description of the Related Art A conventional wiring structure of a speaker mounted on a door of a vehicle will be described below with reference to FIGS.

In the conventional wiring structure of the speaker 30, the speaker 30 is connected to the wire harness 36 of the vehicle by connecting the lead wire 33 having one end connected to the terminal 32 of the speaker 30 to the speaker frame 31 as shown in FIG. The connector 35 is inserted through the bushing 34 and is attached to the other end of the lead wire 33, and the connector 37 is attached to a wire harness 36 of the vehicle.

In this case, in order to actually mount the speaker 30 on the door 40 of the vehicle, the mounting hole 41 and the four mounting holes 42 are provided in the wall portion 40a of the door 40 shown in FIGS. The speaker 3 is attached to each mounting hole 42, the speaker 30 is inserted into the mounting hole 41, and screws are screwed into the respective grommet 43 from the four insertion holes 38 of the speaker 30.
0 is fixed to the wall portion 40a.

[0005]

However, in the case of the above-described conventional speaker wiring structure for a vehicle, the lead wire 33 from the terminal 32 to the connector 35 must be an aerial wire, and the work of connecting the connectors 35 and 37 is required. In order to prevent abnormal noise, connect the connectors 35 and 37 to the wall portion 40a.
The wiring work is extremely complicated because it is necessary to fix it to the terminal 32, and it is necessary to apply an adhesive to the terminal 32 in order to prevent water from leaking into the core wire of the lead wire 33 due to water splashing on the terminal 32. There was a problem.

An object of the present invention is to provide a speaker wiring structure for a vehicle, which can eliminate the complicated work of the conventional example and can greatly simplify the wiring work.

[0007]

The speaker wiring structure for a vehicle according to the present invention uses a flexible printed circuit board, one end of which is connected to a coil of a speaker body and the other end of which is led out along a groove provided in a speaker frame. With the lead wire,
The other end of this lead wire is fixed at the position of the mounting hole of the speaker frame, and the end fixing device attached to the end of the wire harness drawn from the vehicle is brought into contact with the conductor wire of the wire harness. At the same time, it has a grommet-integrated type terminal portion for fixing the speaker frame to an attachment target.

[0008]

The function of the present invention will be described below. According to this speaker wiring structure for a vehicle, one end of the speaker wiring is connected to the coil of the speaker body using a lead wire using a flexible printed circuit board, and the other end side is led out along a groove provided in the speaker frame. , While fixing the speaker frame at the position of the mounting hole of the speaker frame, and by the grommet-integrated terminal part attached to the end of the wire harness derived from the vehicle, while contacting the conductor of the wire harness with the end fixture. Since the speaker frame is fixed to the mounting target, the connection between the lead wire and the wire harness can be completed at the same time as fixing the speaker mounting target, and the complicated work as in the conventional example is eliminated. Wiring work can be greatly simplified.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. In the wiring structure of the vehicle speaker 1 shown in FIG. 1, one end is connected to the coil of the speaker body 2, and the other end side is a lead wire using a flexible printed circuit board led out along a groove 4 provided in the speaker frame 3. 5, an end fixing tool 7 for fixing the other end side of the lead wire 5 at the position of the mounting hole 6 of the speaker frame 3, and the end fixing fixed to the end of the wire harness 8 led out from the vehicle. The tool 7 has a grommet-integrated terminal portion 9 for fixing the speaker frame 3 to an attachment target while contacting the conductor wire of the wire harness 8. Around the speaker body 2, a seal sponge 10 is attached in a circular arrangement.

As shown in FIG. 2, the speaker frame 3 has a branch groove 4 corresponding to the branch portion 5a of the lead wire 5.
A is formed, and a positioning boss 11 is projectingly provided in the branch concave groove 4a corresponding to the boss insertion hole 5b provided in the branch portion 5a. Then, the branch portion 5a of the lead wire 5 is fitted into the branch concave groove 4a, and the positioning boss 11 is inserted into the boss insertion hole 5b to fix the lead wire 5.

As shown in FIGS. 2 and 3, the seal sponge 10 is applied to the inside of the branch 5a of the lead wire 5.

The end fixture 7 is, as shown in FIG.
The connection terminal 12 connected to the lead wire 5 is attached to the mounting hole 6 of the groove 4 of the speaker frame 3, and
By attaching a crimp terminal fitting 13 to the connection terminal 12 and performing a crimping operation, the connection terminal 12 connected to the lead wire 5 is fixed in the mounting hole 6.

FIG. 5 shows the construction of the grommet-integrated terminal portion 9, which comprises a waterproof grommet 20 having a mounting recess 21 for mounting in a door inner panel 45 constituting a wall 40a of the door 40. And this grommet 20
Grommet integrated terminal 24 is constituted by crimping the grommet caulking terminal 23 attached to the end portion of the wire harness 8 to the terminal caulking notch 22 provided in the terminal, as shown in FIG. The end fixture 7 attached to the hole 6
By stacking the grommet-integrated terminal 24 on and screwing in the screw 25, the connection between the end fixture 7 and the wire harness 8 and the attachment of the speaker frame 3 to the door inner panel 45 are simultaneously performed.

Next, an application example of the above wiring structure will be described with reference to FIGS. First, as shown in FIG. 7, of the four mounting holes 42 provided in the door inner panel 45 that forms the wall portion 40a of the door 40, the grommet-integrated terminals 24 are provided at two locations and the grommet-integrated terminals 24 are provided at the other two locations. A normal grommet 43 is attached. Next, as shown in FIG. 8, the speaker 1 is inserted into the mounting hole 41, and the screws 25 are respectively inserted into the two end fixtures 7 on the speaker frame 3 side and screwed into the grommet-integrated terminal 24. Grommet 4 in the other two places
The screws 25 are also screwed into each of the three.

As a result, the speaker 1 can be attached to the door inner panel 45 with a very simple operation. Then, the wiring work is completed at the same time as the mounting work of the speaker 1, the wiring of the lead wire 5 is easy, and it is not necessary to use a connector. Furthermore, the work of applying an adhesive for waterproofing is also unnecessary. The present invention can be variously modified within the scope of the invention in addition to the above-described embodiments.
