Description

  The present invention inserts the speaker wire and the ground wire of the speaker into the front opening of each of the pair of left and right small casings provided on the rear panel, and then sandwiches these wires in the front opening. The present invention relates to a speaker wire connection structure which is to be attached.

Conventionally, as shown in FIG. 3, this type of speaker wire connection structure has a speaker 104 in the front openings 102a and 103a of a pair of left and right small housing-like mounting portions 102 and 103 provided on the rear panel 101. When the speaker wire 105 and the ground wire 106 are inserted, the knobs 106 and 107 provided on the left and right ends of the attachment portions 102 and 103 are rearward one by one against the urging force of the springs 108 and 108, respectively. To increase the degree of opening of the front openings 102a and 103a, and then insert one speaker wire 105 and one ground wire 106 into the front openings 102a and 103a, and then release the knobs 103 and 107 one by one. Then, the knob is moved to the front side by the urging force of the springs 108 and 108 to reduce the opening degree of the front openings 102a and 103a. The speaker line 105 and the ground wire 106 have to attach to sandwich one by one.
However, since the knobs 106 and 107 are provided as a pair of left and right knobs, the knobs 106 and 107 are pushed one by one to increase the degree of the front openings 102a and 103a one by one. There is a problem in that it takes time and effort because it is necessary to insert them one by one.

The first prior art is shown in FIGS. 4 and 5A and 5B. Multi-channel speaker provided with a plurality of terminals 202a and 202b, which are connected to audio and video equipment circuits, and are connected to + and-terminals of speaker plug PL of two or more channels, respectively. In the terminal ST, the side where the speaker plug PL is inserted is colored in a different color for each channel. (For example, refer to Patent Document 1).
However, in this case, as shown in FIG. 5B, it is difficult to insert the wires 208a and 208b of the cable 208 in a state where the pressing portions 209a and 209b of the cable pressing member 209 are in contact with the connection terminals 6a and 6b. There was a problem.

JP 2003-109706 A

  The present invention solves the above-mentioned conventional problems, and inserts the speaker wire and the ground wire of the speaker at a time and attaches the speaker wire and the ground wire to a pair of left and right small housing-like mounting portions of the rear panel by a single operation. In addition, an object of the present invention is to provide a speaker line connection structure that can be easily inserted and attached easily.

  That is, by simply tightening the handle portion of the substantially scissor-shaped clamping member and opening the front opening of the pair of left and right small housings, the speaker wire and the ground wire of the speaker are connected to the front opening of the mounting portion. These speaker wires and ground wires can be attached to a pair of left and right small housing attachments on the rear panel with a single operation that can be inserted at a time and the left and right grips of the substantially scissor-shaped clamping member are released. These speaker wires and ground wires are easy to insert and can be quickly connected and attached.

  According to the second aspect of the present invention, after the speaker wire and the ground wire of the speaker are inserted into the front opening of each of the pair of left and right small housings provided on the rear panel, In the speaker wire connection structure in which the wire is pressed and clamped, a gripping member having a tip inserted into the inside from the outer wall of the pair of left and right small housings is attached, and the left and right grips of the gripping member An elastic body biased outward is interposed between the two parts, and when the left and right handle parts are tightened, the openings of the small housing-like mounting parts are opened, and the left and right handle parts are free. When it is in a state, the handle part is opened by the urging force of the elastic body and the tip moves to the near side so that the speaker wire and the ground wire are pressed and clamped so that they are connected to the small housing-like attachment part. The following effects are achieved.

  That is, the speaker wire and the ground wire of the speaker can be inserted into the front opening of the mounting portion at once by simply tightening the grip portion of the clamping member and opening the front opening of the pair of left and right small housings. The speaker wire and the ground wire can be attached to the pair of left and right small housings on the rear panel with a single operation by simply separating the left and right grips of the clamping member. Easy to insert and quick to connect and attach.

  According to a third aspect of the present invention, a receiving plate having a substantially L-shaped planar visual acuity for forcibly bending and attaching the speaker wire and the ground wire is disposed in each attachment portion having a small casing shape. Therefore, the speaker wire and the ground wire can be securely attached without being unintentionally disconnected.
