Abstract
The utility model relates to an integrated cannon plug based on a lithium battery charger. The cannon plug comprises a front device, a back device and an inner base, wherein the inner base is fixed inside the front device, two electrode pins are disposed in the inner base in an axial and parallel manner, one ends of the electrode pins pass through the inner base, the other ends of the electrode pins are disposed at the inner side of the inner base and are welded with two output wires of a lithium battery charger. The cannon plug achieves the main technical characteristics that the back device is tightly fixed with the front device and the inner base in a manner of injection moulding, and the wires are wrapped inside the back device. The cannon plug is reasonable in design, employs integrated structure to ensure good contact performance between the electrode pins and the wires, so that product performance is improved, and the cannon plug is characterized by having light weight, anti-friction, good rigidity, high insulation and low cost.
Description
Technical field
The utility model belongs to the lithium battery charger technical field, especially a kind of integral type blocking head based on lithium battery charger.
Background technology
Lithium battery charger is the equipment of electric bicycle indispensability.Lithium battery charger can adopt multiple output line joint, and wherein blocking head is a kind of joint commonly used wherein.The blocking head of existing lithium battery charger is the front and back end split-type structural, adopt welding manner to be installed between the inner chamber of front and back end between electrode needle and the wire, there are following problems in it: 1, since blocking head often plug can cause the solder joint loose contact, cause blocking head to damage, can not normally use; 2, the front end of blocking head adopts stainless steel material to make, and its cost is higher; 3, adopt split-type structural and be done manually to install and produce, the lower and quality of production of its production efficiency is difficult to guarantee.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design, stable performance, cost is low and efficient the is high integral type blocking head based on lithium battery charger are provided.
The utility model solves existing technical problem and takes following technical scheme to realize:
A kind of integral type blocking head based on lithium battery charger, comprise fore device, back-end device and inner pedestal, inner pedestal is packed in the fore device, axially parallel is equipped with two electrode needle on inner pedestal, one end of two electrode needle is arranged on the outside of inner pedestal, the other end of two electrode needle is arranged on the inboard of inner pedestal and welds together with two output leads of lithium battery charger, back-end device adopts the injection moulding mode and fore device, inner pedestal closely are solidly installed and with conducting wire cladding in back-end device.
And, also being provided with on the described inner pedestal and two pilot pins that electrode needle is parallel, an end of this pilot pin is arranged on the outside of inner pedestal.
And described fore device is circular cylinder body.
And described fore device adopts nylon material to make.
And described back-end device is that the PVC material is injection molded.
Advantage of the present utility model and good effect are:
1, this blocking head adopts integral structure that electrode needle is connected reliably with wire to be fixed together, this entity mounting structure has guaranteed the good contact performance of electrode needle and wire, the problem that can not cause plugging the loose contact that causes occurs, and has improved the performance of product.
2, this blocking head adopts the mode of integral molded plastic to produce, and has improved the gentle production efficiency of Automated water of producing, and has improved the quality of production of product.
3, this blocking head front end adopts nylon material to make, and has the characteristics such as lightweight, rub resistance, good rigidly, insulating properties are strong, with low cost.
