Description
Technical field
The utility model belongs to lithium battery charger technical field, especially a kind of novel integrated aviation head based on lithium battery charger.
Background technology
Lithium battery charger can connect multiple output line joint, and wherein aviation head has the features such as volume is little, contact pin figure place is optional, exquisite appearance and is widely used.The aviation head of existing lithium battery charger is front and back end split-type structural, welding manner is adopted to be arranged between the inner chamber of front and back end between electrode needle and output lead, there are following problems in this structure: 1, because aviation head in use needs frequent plug, therefore solder joint can be caused to ftracture or loose contact, cause aviation head to damage, can not normally use; 2, the rear end of aviation head adopts metal material to make, and its cost is higher; 3, because aviation head small volume capillary is more, therefore in assembling process after welding, be easily short-circuited between capillary, between capillary and metallic object rear end phenomenon; 4, because existing aviation head adopts split-type structural, therefore manual mode must complete installation production, its production efficiency is lower and the quality of production is difficult to guarantee.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, stable performance, cost low and the novel integrated aviation head based on lithium battery charger that efficiency is high.
The utility model solves existing technical problem and takes following technical scheme to realize:
A kind of novel integrated aviation head based on lithium battery charger, comprise fore device, back-end device and outside line card, axially parallel slotting spring is installed fore device is inner, insert the spring body of spring to divide and be embedded in fore device, insert the capillary part of spring to be arranged on outside fore device and to weld together with the output line of the inner axially parallel installation of back-end device, described output line is connected with lithium battery charger through outside line card and RVV; Back-end device is solidified togather by injection molding manner and fore device, the output line welded together with the capillary part of slotting spring, outside line card, RVV.
And described fore device is cylindrical shape.
And described fore device adopts bakelite material to make.
And described back-end device adopts PVC material injection molding to make.
Advantage of the present utility model and good effect are:
1, this aviation head adopts integrated formed structure, ensure that the good contact performance that slotting spring welds with output line, each parts firmness strengthens greatly, and the problem of the loose contact that can not cause because of frequent plug or other External Force Actings occurs, improves the stability of product.
2, this aviation head adopts the mode of integral molded plastic to produce, and improves the gentle production efficiency of Automated water of production, improves the quality of production of product, saved cost.
3, the back-end device of this aviation head adopts PVC injection moulding, effectively prevents back-end device from adopting the short circuit phenomenon between metal material and inner capillary to occur, improves overall insulating properties and fail safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-fore device, 2-inserts spring, 3-output line, 4-RVV, 5-back-end device, the outside line card of 6-.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
Based on a novel integrated aviation head for lithium battery charger, as shown in Figure 1, fore device 1, back-end device 5 and outside line card 6 is comprised.Described fore device is cylindrical shape and adopts bakelite material to make, axially parallel three slotting springs 2 are installed fore device is inner, insert the spring body of spring to divide and be embedded in fore device, the capillary part of inserting spring is arranged on outside fore device, the capillary part of inserting spring welds together with two output lines 3 of the inner axially parallel installation of back-end device, and two output lines are connected with lithium battery charger through outside line card and RVV 4.Back-end device is PVC material, it adopts one-time formed PVC injection molding manner fore device, the output line welded together with the capillary part of slotting spring, outside line card, RVV to be solidified togather, the structure adopting fore device, back-end device, outside line card and RVV to be solidified togather, greatly strengthen the firmness that all parts connects; The solder joint 7 inserted between the capillary part of spring and output line is solidificated in back-end device tightly, thus is ensure that the good contact performance that slotting spring welds with output line.Two output lines are actually two in lithium battery charger output line, and RVV adopts two core RVV to protect two wires, outside line card and back-end device one-body molded to carry out available protecting to lithium battery charger output line.
This aviation head is when producing, first the output line of two in lithium battery charger output line is welded in the capillary part of corresponding slotting spring, then to be placed on corresponding mould and to adopt PVC material single injection-molded, making fore device, back-end device, the output line welded with slotting spring and outer lines card solidify to form integral type aviation head.
Above-described embodiment is described with three conventional core aviation head structures, in fact for two core aviation plugs or multi-core aviation plug applicable equally.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other execution modes drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
