Abstract
The utility model discloses an audio signal plug, which comprises a spindle, a front end electrode and a rear end electrode, wherein the front end electrode and the rear end electrode are positioned at the two ends of the spindle; n middle electrodes are also arranged between the front end electrode and the rear end electrode; the rear end electrode has a tubular structure, and the outer wall of the rear end electrode is provided with an annular flange; particularly, the inner wall of the flange of the tubular rear end electrode, which is formed from a metal plate by deep drawing, constitutes an annular groove, i.e. a cavity structure is formed in the flange; and when molten plastic is injected into a cavity of each tubular electrode to retain each electrode on the spindle, molten plastic is also filled in the groove, so that the rear end electrode is fastened to the spindle. The audio signal plug has the beneficial effects that: the rear end electrode can be formed from the copper plate by deep drawing, so that production of cutting scraps is greatly reduced and the production cost is reduced; a plastic injection process is favorably combined; and stand-alone automatic high-efficiency production is realized. Meanwhile, the rear end electrode using the structure becomes firmer when the molten plastic is injected for retaining and shaping.
Description
Technical fieldThe utility model relates to the contact coupling, particularly relates to being used for the plug that audio signal connects.
Background technologyThe audio signal plug of prior art generally is two electrodes, three electrodes or four electrodes, comprises column mandrel and each electrode; One end of said mandrel is preceding termination electrode; Be with back termination electrode 30 ' at its other end, this back termination electrode 30 ' is a tubulose, at the pipe outer wall collar flange 31 ' is arranged; Between preceding termination electrode and back termination electrode, the middle electrode of one or two tubulose can also be arranged, thereby constitute three required electrodes or four electrode plugs; In process of production, prior art is through manual each hollow edged electrode to be inserted in said mandrel successively, and the plastics with fusion are injected in the pipe of each electrode from the rear end electrode again, make that each electrode retaining collar and mandrel are separated mutually and fixing is an one.Said each electrode of prior art is to adopt the metal material that conducts electricity very well, and like brass bar, turning shapes, and the flange 31 ' of particularly said back termination electrode 30 ' is a solid construction, as shown in Figure 7.Many institutes adopt the turning copper rod to process in the process of hollow edged electrode ring with knowing, can produce more metal cutting waste material, cause wastage of material, make processing cost higher.
The utility model contentThe technical problem that the utility model will solve is to avoid the weak point of above-mentioned prior art and designs and produce a kind of audio signal plug, solves in the prior art manufacture craft and causes waste of material, cost height and the low problem of hand assembled production efficiency.
The utility model is to solve the problems of the technologies described above the technical scheme that proposes to be, a kind of audio signal plug, and the preceding termination electrode and back termination electrode that comprise mandrel and be positioned at its two also are provided with n middle electrode between said preceding termination electrode and the back termination electrode; This back termination electrode is a tubular structure, and a collar flange is arranged on its outer wall; Particularly, with the flange of termination electrode behind the tubulose of sheet metal deep hole pinching, its inwall constitutes annular recess, also is that said flange inside is cavity body structure; When the plastics of fusion be injected into the inner chamber of each hollow edged electrode, with each electrode of fixing on said mandrel the time, the also plastics of full fusion in this groove, order back termination electrode is anchored on the mandrel.
Crown front end electrode is fixed in said mandrel leading section.
A said n middle electrode, n=0,1,2 or 3, and be sleeved on the middle part of said mandrel successively.
Compare with prior art, the beneficial effect of the utility model is: the annular flange flange of said back termination electrode, and its inner chamber is groove ringwise, can shape with copper sheet material deep-draw; Compare with the mode of production of copper rod turning with prior art, significantly reduced waste cut materials generation, reduced production cost, help combining the plastics injection technique, realize the high efficiency production of single plane automation.Simultaneously, the back termination electrode that adopts this structure can be more fastening when the plastics fixing setting of injecting fusion.

EmbodimentBelow, further set forth the utility model in conjunction with each preferred embodiment shown in the accompanying drawing.
Referring to Fig. 1 to Fig. 4; The preferred embodiment one of the utility model is; A kind of five electrode audio jack are produced in design, and the preceding termination electrode 20 and back termination electrode 30 that comprise mandrel 10 and be positioned at its two also are provided with 3 middle electrodes 40 between said preceding termination electrode 20 and the back termination electrode 30; This back termination electrode 31 is a tubular structure, and a collar flange 31 is arranged on its outer wall.
Said each electrode 40,30 all adopts the sheet metal deep-draw to become required shape, and especially, the copper sheet material deep-draw of said back termination electrode 30 usefulness adds man-hour, and at flange 31 inner wall forming annular recess 311, also promptly these flange 31 inside are cavity body structure.When the plastics of fusion be injected into the inner chamber of each hollow edged electrode 30,40, separating and fixing mandrel 10 and each electrode 30,40 when be one, also full molten plastic in this groove 311, order afterwards termination electrode 30 is anchored on the mandrel 10 more.
Just as shown in Figures 2 and 3, in this example, the crown preceding termination electrode 20 that is shaped with metal bar turning is fixed in the mandrel suitable with it 10 leading sections.
Referring to Fig. 1 to Fig. 3 and Fig. 5; The preferred embodiment two of the utility model is, a kind of four electrode audio jack are produced in design, and its structure is similar basically with mode of production previous embodiment one; Maximum do not coexist with: middle electrode ring 40 has only 2, and miscellaneous part is the trickle change of shape and structure.
Referring to Fig. 1 to Fig. 3 and Fig. 6; The preferred embodiment one of the utility model is; A kind of three electrode audio jack are produced in design; Its structure is similar basically with mode of production previous embodiment one, maximum do not coexist with: just one on middle electrode ring 40, miscellaneous part is the just trickle change of shape and structure also.
