Coupler for connecting wire

Abstract

The present invention relates to a plug for the connection of wires, which provides sufficient retaining force for lead-in wires (5, 7) to prevent the lead-in wires (5, 7) from breaking, and provides contact resistance of predetermined value.

Description

technical field [0001] The present invention relates to a plug for connecting wires to audio equipment, etc., and more particularly, the present invention relates to a plug for connecting wires composed of a pair of L and R signal lines to speakers, audio equipment, etc. plug. Background technique [0002] As a device that uses wires to distribute lines, such as amplifiers and speakers of audio equipment, they are connected by wires consisting of a pair of L and R signal wires. To connect the lead wires to these devices, the end sheath of the lead wires is usually stripped off, and as shown in FIG. [0003] The lever terminal 103 resists the torque of the coil spring 107 to rotate the lever 105 clockwise in the drawing, and inserts the end of the stripped wire 109 into the insertion hole 111 . Then, if the handle 105 is returned to the original position, the wire 109 will be bitten between the contact fitting 113 integrally arranged on the lever 105 and the contact fitting...

Problems solved by technology

[0016] On the other hand, in the structure of the electric wire connection plug 200 that obtains the holding force of the lead wires 5, 7 only by clamping the lead wires 5, 7 as described above, there is a limit in ensuring the holding force, and it cannot be completely to solve the problem

[0017] Again, since the sharp-angled front end of the plate spring 223 is crimped and engaged with the stripped portion 250 of the lead 5,7, the peeled portion 250 is easily partially broken, and the lead 5,7 cannot be reused repeatedly due to the breakage.

[0018] Some of the partially broken wires at the stripped part 250 may remain in the box body 210 or in the machine-side socket 127, which may result in poor insulation.

[0019] Furthermore, the positions of the front ends of the leaf springs 223 abutting against the wires 5, 7 are different each time because of the insertion state of the wires 5, 7, so the amount of deflection of the leaf springs 223 will change, resulting in a discrepancy with the wires 5 and 7. , 7 The instability of the contact pressure

Therefore, the contact resistance will change, and the circuit connection characteristics cannot be obtained as the original design value
