Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that execution mode is mentioned is not to restriction of the present utility model.
Be the embodiment one of a kind of audio frequency contact pin with attachment pcb board of the utility model as depicted in figs. 1 and 2, comprise audio frequency male 1 and welding afterbody 2, this audio frequency male 1 comprises multiple conduction pluggable terminals 3 and the interlayer insulating layer 4 for the multiple conduction pluggable terminals 3 in interval, also comprise and the pcb board 5 welding afterbody 2 and be fixedly connected with, described welding afterbody 2 is provided with the electric connecting plate 6 that multiple and described conduction pluggable terminals 3 is electrically connected respectively, the tail end of this pcb board 5 is provided with multiple pad 7, and the plurality of pad 7 is electrically connected with described multiple electric connecting plate 6 one_to_one corresponding.
The utility model is by the improvement to audio frequency contact pin, welding space is transferred to by narrow and small welding afterbody 2 in the welding position of audio frequency contact pin comparatively large and on the pcb board 5 of convenient welding, in the welding process of audio frequency contact pin and earphone cord, only need earphone cord upper conductor end to carry out welding with the pad 7 on pcb board 5, greatly reduce audio frequency contact pin and weld difficulty between earphone cord; Owing to being that wire termination is welded with the pad 7 on pcb board 5, existing automatic welding equipment or surface-mounting equipment is adopted to carry out automation processing, the production efficiency of earphone is significantly improved, and greatly reduce earphone cord production cost, practicality is stronger.
In the present embodiment, described pad 7 is juxtaposed on described pcb board 5 in yi word pattern, and concrete, the distance between adjacent described pad 7 is equal.In the automation batch welding process of earphone cord and audio frequency contact pin, all unified welding specification, be convenient to the automation processing of automatic welding equipment, only need to do small change to the holder part of existing welding equipment, the input of further reduction automation equipment and maintenance cost, technique effect is more remarkable.
In the technical program, when described audio frequency contact pin is only used as transmission of audio signal, conduction pluggable terminals 3 only needs three can meet the demands, and now the quantity of described conduction pluggable terminals 3, electric connecting plate 6 and pad 7 is three; But when described audio frequency contact pin is used as the contact pin of handset earphone line, not only want energy transmission of audio signal, also need to carry out certain transfer of data or X-by-Wire, now the quantity of described conduction pluggable terminals 3, electric connecting plate 6 and pad 7 is four, technical solutions of the utility model can be applicable to above-mentioned two situations simultaneously, and applicability is wider.
In the present embodiment, described pcb board 5 offers installation gap 8, and described welding afterbody 2 is fixedly embedded in this installation gap 8; Concrete, the quantity of described conduction pluggable terminals 3, electric connecting plate 6 and pad 7 is four, and wherein two electric connecting plates 6 are fixedly connected with the side of pcb board 5, and two other electric connecting plate 6 is fixedly connected with the side of pcb board 5.Four electric connecting plates 6 lay respectively at the both sides of pcb board 5 and grip pcb board 5, and substantially increase pcb board 5 and described connection tightness of welding between afterbody 2, the earphone cord durability produced thus is stronger.
Be illustrated in figure 3 the embodiment two of a kind of audio frequency contact pin with attachment pcb board of the utility model, be with the difference of above-described embodiment one: described pad 7 is arranged in described pcb board 5 in two two modes arranged of arranging.Under the prerequisite not affecting plug-in mounting welding processing, structure is compacter, thus greatly reduces the overall dimension of audio frequency contact pin, and during encapsulation injection moulding, materials are less, and profile is more attractive in appearance.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
