Abstract
The utility model provides an audio connecting wire for musical instrument, including wire rod and terminal core, wire rod and terminal core electric connection, the junction outside of wire rod and terminal core is equipped with insulating seal portion, insulating seal portion's the outside is equipped with the rigidity protecting crust, seals terminal core and wire rod junction through insulating seal portion, has avoided with external direct contact, improves the quality and the life of junction, and simultaneously, sets up the rigidity protecting crust in insulating seal portion's the outside, can wrap up this junction, to the further protection of junction, improves life, also can be completely cut off junction and outside simultaneously, avoids the influence of external signal to the junction.
Description
Technical Field
The utility model belongs to the wire rod field specifically relates to an audio frequency connecting wire for musical instrument.
Background
Audio frequency connecting wire is at playback devices and audio amplifier, the cable of transmission sound signal between the earphone, when being used for the musical instrument output, the audio frequency line generally adopts 6.5mm specification, at this moment, welding after the convenient appearance problem, generally all be in wire rod and terminal core hookup location outside through threaded connection with wire rod and terminal core protection, fix the shell in the terminal core and the wire rod outside through threaded connection, can protect, convenient dismantlement, but, because threaded connection also can communicate with the external world at the junction, in-process when using, damage easily appears in the junction inside, influence life.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a to the problem among the prior art, provide an audio frequency connecting wire for musical instrument now, sealed with terminal core and wire rod junction, increase the intensity of junction, increase life.
The utility model provides an audio frequency connecting wire for musical instrument, including wire rod and terminal core, wire rod and terminal core electric connection, the junction outside of wire rod and terminal core is equipped with insulating seal portion, insulating seal portion's the outside is equipped with the rigidity protecting crust.
Preferably, the insulation sealing part is fixed to a junction of the wire and the terminal core by overmolding.
Preferably, parallel grooves are formed in the joint of the wire and the insulating sealing part, and the insulating sealing part after secondary forming is fixed to the grooves of the wire.
The utility model has the advantages that: seal terminal core and wire rod junction through insulating seal portion, avoided with external direct contact, improve the quality and the life of junction, simultaneously, set up the rigidity protecting crust in insulating seal portion's the outside, can wrap up this junction, to the further protection of junction, improve life, also can be completely cut off junction and outside simultaneously, avoid the influence of external signal to the junction.
Drawings
Fig. 1 is an overall schematic view of the audio cable of the present invention;
the terminal comprises a terminal core 1, a terminal core 2, a wire 3, an insulating sealing part 4 and a rigid protection shell.
Detailed Description
The technical solution of the present invention is described below, without limitation, with reference to the accompanying drawings, for the purpose of better understanding the technical contents by the public.
Examples
As shown in fig. 1, the audio connection line for a musical instrument comprises a wire 2 and a terminal core 1, wherein the wire 2 is electrically connected with the terminal core 1, an insulating sealing part 3 is arranged on the outer side of the joint of the wire 2 and the terminal core 1, and a rigid protective shell 4 is arranged on the outer side of the insulating sealing part 3.
Specifically, on the basis of original audio frequency connecting wire, be equipped with insulating seal portion 3 in the outside of wire rod 2 and the 1 junction of terminal core, it is fixed with wire rod 2 and the 1 junction of terminal core through insulating seal portion 3, and seal completely with the external world, at this moment, the junction is direct to be filled through insulating seal portion 3, not only can protect the junction, avoid the in-process that uses to take place the short circuit, and avoid the junction to take place the rupture, and simultaneously, be provided with rigidity protecting sheathing 4 in the outside of sealing seal portion, 3 holistic intensity of insulating seal portion can further increase, and simultaneously, when rigidity protecting sheathing 4 adopts when can shielding magnetic field class material (for example iron), can carry out a protection to the junction, avoid the data transmission of external environment interference junction.
Wherein, can adopt the form setting of post forming or winding parcel to insulating sealing 3, in this embodiment, for the convenience of production and processing, insulating sealing 3 is fixed through post forming and wire rod 2 and terminal core 1 junction, specifically, after being connected terminal core 1 and wire rod 2 through welding or other modes, place its whole in the mould of adaptation, fix insulating sealing 3 in the outside of junction through the post forming of moulding plastics, at this moment, insulating sealing 3 can adopt materials such as polyvinyl chloride or polyethylene or polypropylene, can be convenient through the post forming of moulding plastics with the fixed junction outside of insulating sealing 3.
Secondly, in order to make the junction of wire rod 2 and insulating sealing portion 3 more firm, being equipped with parallel recess in the junction of wire rod 2 and insulating sealing portion 3, insulating sealing portion 3 after the post forming is fixed with the recess of wire rod 2, like this, can be fixed more firm with insulating sealing portion 3 and wire rod 2, in the in-process of using, be difficult to appear damaging.
Seal terminal core 1 and 2 junctions of wire rod through insulating seal portion 3, avoided with external direct contact, improve the quality and the life of junction, simultaneously, set up rigidity protecting crust 4 in insulating seal portion 3's the outside, can wrap up this junction, to the further protection of junction, improve life, also can completely cut off junction and outside simultaneously, avoid the influence of external signal to the junction.
It should be understood that the above-mentioned description including the accompanying drawings is not intended to limit the technical solutions, and in fact, modifications to the technical solutions, including shapes of structures of various parts, dimensions, materials used, and equivalents of substantially the same functional structures, are within the technical solutions claimed in the present invention under the same or similar principles.
