Abstract

An elastic wire relates to the packaging field of wires, in particular to increase the elasticity of the wires and reduce the risk of the wires being broken. Commonly used headphone wires are generally several groups, and each group has multiple thin copper enameled wires. Often the copper wires of the headphone wires are broken due to pulling, which makes the headphones unusable. The invention enhances the elasticity of the wire and reduces the risk of the wire being broken. The technical solution is: several groups of threads are arranged on the cylindrical elastic column, each group of threads is wound with one or a group of wires, and then a layer of elastic is wrapped outside. For the elastic wires used in the earphones, arrange three sets of threads on the elastic column with a diameter of 4-5mm, the radius of curvature of the threads is 1mm, and the depth is 1mm, respectively wrap the wires of the left channel, the common line, and the right channel, and then wrap them outside A layer of elastic. The beneficial effect is that: since the elastic band can be extended, the helical wire can also be extended, which can reduce the strain borne by the wire under stretching, reduce the damage of the wire, and prolong the service life.

Description

an elastic wire

technical field

The invention relates to the packaging field of wires, in particular to increase the elasticity of wires and reduce the risk of wires being broken.

Background technique

Commonly used earplug wires are generally several groups, and each group has multiple thin copper wires, usually enameled wires.

When listening to obstacles, or when the listener has hand movements, he often forgets that he is listening to the earphones, causing the earphone wires to be pulled frequently. Because the earphone wires lack elasticity and are relatively slender, these sudden pulls, It often causes the copper wire of the earphone wire to be broken, resulting in an increase in local impedance, which further aggravates the thermal effect here, making it easier to burn out here, making the earphone unusable.

Contents of the invention

The sound quality effect of the earphone mainly lies in the earplugs, while the easily damaged parts are the wires. The damage of the secondary parts leads to the failure of the main parts.

The technical solution adopted by the present invention to achieve the purpose of the invention is: arrange several groups of threads on the cylindrical elastic column, wind each group of threads to wind one or a group of wires, and then wrap a layer of elastic outside.

For the elastic wire used in the earphone, arrange three sets of threads on the elastic column with a diameter of 4-5mm, the radius of curvature of the thread is 1mm, the depth is 1mm, the pitch within the group is 2mm, and the pitch between groups is 1-2cm; the left channel is respectively wound , the common line, the wire of the right channel, and then wrap a layer of elastic outside.

The beneficial effects of the invention are: since the elastic band can be extended, the spiral wire can also be extended, which can reduce the strain borne by the wire under stretching, reduce the damage of the wire, and prolong the service life. the

Description of drawings

Figure 1 is a schematic diagram of the elastic wire.

Wherein, 1, elastic column, 2, groove.

Detailed ways

Arrange the groove 2 spirally on the elastic column 1 with a diameter of 4-5mm, similar to a threaded screw, arrange the corresponding number of thread groups according to the number of wires to be arranged, for example, if the earphone needs three wires, arrange three groups Threads, the three sets of threads are not connected, each wire is wound on one set of threads, and then wrapped with a layer of elastic outside.

Claims (2)

1. An elastic wire, characterized in that several groups of threads are arranged on the cylindrical elastic column, each group of threads is wound with one or a group of wires, and then wrapped with a layer of elastic outside. 2. A kind of elastic wire according to claim 1, characterized in that: for the elastic wire used in earphones, three groups of threads are arranged on the elastic column with a diameter of 4-5mm, the radius of curvature of the threads is 1mm, and the depth is 1mm. The inner thread pitch is 2mm, and the thread pitch between groups is 1-2cm; respectively wrap the wires of the left channel, the common line, and the right channel, and then wrap a layer of elastic outside.
