Abstract
The utility model discloses a plug-in type's earphone DC head wiring structure, be fixed with on the plug and keep off the ring, and the wire upwards is fixed with the rubber sleeve that extends to on the plug to circumference. The rubber sleeve is sleeved on the plug and tightly abuts against the side face of the blocking ring, the upper side and the lower side of the left end of the rubber sleeve extend leftwards to form a connecting portion penetrating through the blocking ring, the tail end of the connecting portion extends along the circumferential direction of the plug to form a circular arc-shaped fixing portion fixed on the plug, and a connecting groove corresponding to the connecting portion is formed in the blocking ring. The back is on the plug in the wire welding, overlaps the rubber sleeve on the plug, then connecting portion pass the spread groove, fix the fixed part on the plug, keep off the ring like this and block the fixed part, avoid the slippage, when glue bonding fixed part guarantees joint strength, for moulding plastics, it is more convenient, the left end face that keeps off the ring inclines right from circumference to the centre to make the fixed part be difficult to outside slippage, also increased connection area, the fastness is better.
Description
Technical Field
The utility model relates to an earphone DC head wiring field of connecting specifically is an earphone DC head wiring structure of plug-in type.
Background
The earphone connector is known that in order to guarantee connection strength, plugging and unplugging are firm, a plug and a wire are generally injected together, the plug and the wire are troublesome, the plug needs to be placed and then injection molded, working hours are increased, and therefore a wiring mechanism capable of improving efficiency while guaranteeing strength is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a plug-in type earphone DC head wiring structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a plug-in type earphone DC head wiring structure comprises a wire and a plug connected with the left end of the wire, wherein a baffle ring is fixed on the plug, and a rubber sleeve extending to the plug is fixed on the circumference of the wire;
the rubber sleeve is sleeved on the plug and tightly abuts against the side face of the blocking ring, the upper side and the lower side of the left end of the rubber sleeve extend leftwards to form a connecting portion penetrating through the blocking ring, the tail end of the connecting portion extends along the circumferential direction of the plug to form a circular arc-shaped fixing portion fixed on the plug, and a connecting groove corresponding to the connecting portion is formed in the blocking ring.
Preferably, the left end surface of the baffle ring is inclined gradually to the right from the circumferential direction to the middle.
Preferably, the fixing part is connected with the plug in a bonding mode through glue.
Preferably, the fixing portion is semi-annular.
Preferably, the opposite ends of the two fixing parts are adhesively connected by glue.
Compared with the prior art, the beneficial effects of the utility model are that:
1. after the lead is welded on the plug, the rubber sleeve is sleeved on the plug, then the connecting part penetrates through the connecting groove, and the fixing part is fixed on the plug, so that the fixing part is blocked by the blocking ring to avoid slipping, and the fixing part is bonded by glue, so that the connection strength is ensured, and the convenience is realized compared with injection molding;
2. the left end face of the baffle ring inclines rightwards from the circumferential direction to the middle, so that the fixing part is not easy to slip outwards, the connecting area is increased, and the firmness is better.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a front view of the present invention;
fig. 3 is a top view of the present invention.
In the figure: 1 lead, 11 plugs, 12 baffle rings, 2 rubber sleeves, 21 connecting parts, 22 fixing parts and 23 connecting grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution of a plug-in type earphone DC jack connection structure: the utility model provides a plug-in type earphone DC head wiring structure, includes wire 1 and the plug 11 of being connected with 1 left end of wire, is fixed with on the plug 11 and keeps off ring 12, and 1 circumference of wire is fixed with rubber sleeve 2 that extends to on the plug 1.
Rubber sleeve 2 cup joints on plug 11, and support the side that keeps off ring 12 tightly, and the downside extends left on the left end of rubber sleeve 2 and forms the connecting portion 21 that passes and keep off ring 12, the end of connecting portion 21 extends along the circumference of plug 11 and forms the convex fixed part 22 of fixing on plug 11, and keep off and set up the spread groove 23 that corresponds with connecting portion 21 on the ring 12, the left end face that keeps off ring 12 inclines right gradually from circumference to centre, fixed part 22 is difficult to outwards slippage like this, area of contact has been increased simultaneously, and is more firm, fixed part 22 passes through glue adhesive connection with plug 11, and high durability and convenient installation, for moulding plastics, this kind is simpler, fixed part 22 is the half ring form, circumference encircles, area of contact is bigger, and is more pleasing to the eye, glue adhesive connection is passed through to the relative one end of two fixed parts 22, increase connection area.
The working principle is as follows: after the wire 1 is welded on the plug 11, the rubber sleeve 2 is sleeved on the plug 11, then the connecting portion 21 penetrates through the connecting groove 23, the fixing portion 22 is fixed on the plug 11, the retaining ring 12 blocks the fixing portion 22 to avoid slipping, the glue is bonded on the fixing portion 22, and meanwhile, the connecting strength is guaranteed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
