Abstract

The utility model relates to the low-voltage frameworks that one kind can fix tail head automatically, including low-voltage framework, playing tail first speed circle in the enameled wire of low-voltage framework, along the circumferential direction there are two L-type notch, the long-armed opening width of L-type notch is identical as enameled wire overall diameter, one of them of notch be enameled wire start notch, another be enameled wire tail head notch.Having the technical effect that for the utility model, reduces costs, and improves working efficiency and around line mass, is suitble to produce in enormous quantities.

Description

A kind of low-voltage framework that can have fixed tail head automatically

Technical field

The utility model relates to a kind of pen-type ignition coil low-voltage frameworks, in particular to a kind of to have fixed tail head automatically Low-voltage framework.

Background technique

In automotive engine ignition system, ignition coil is the component for generating high pressure, the quality of electric property and service life Directly influence the working performance of entire automotive ignition system.Wherein low-voltage framework is the coiling carrier of enameled wire, structure ruler Very little design will guarantee space required for carrying the performance of coil, in favor of designing the bone for being able to satisfy electrical property coiling demand Frame.What traditional skeleton coiling played the outlet of tail head is designed as circular hole, when machine coiling the line that needs to start manually penetrate circular hole It is fixed, line is cut after coiling manually and tail head line is pierced by fixation from circular hole.Time-consuming and laborious, working efficiency is very low, is not suitable for big Batch production.Therefore, a kind of novel low-pressure line-outgoing mode is developed, improving low pressure winding efficiency is that ignition coil designer exerts The direction of power.

Summary of the invention

In view of the problems existing in the prior art, the utility model provides a kind of low-voltage framework that can have fixed tail head automatically, Specific technical solution is a kind of low-voltage framework that can have fixed tail head automatically, including low-voltage framework, it is characterised in that: in low pressure The enameled wire of skeleton plays tail first speed circle along the circumferential direction there are two L-type notch, outside the long-armed opening width and enameled wire of L-type notch Diameter is identical, one of them of notch be enameled wire start notch, another be enameled wire tail head notch.

Having the technical effect that for the utility model, reduces costs, and improves working efficiency and around line mass, is suitble to high-volume raw It produces.

Detailed description of the invention

Fig. 1 is the skeleton structure top view of the utility model；

Fig. 2 is the three-dimensional structure diagram of the utility model.

Specific embodiment

As shown in Figure 1, 2, a kind of low-voltage framework that can have fixed tail head automatically, including low-voltage framework, in low-voltage framework Enameled wire plays tail first speed circle 1 along the circumferential direction there are two L-type notch 2, and the long-armed opening width and enameled wire 3 of L-type notch 2 are straight outside Diameter is identical, one of them of notch 2 be enameled wire start notch 2-1, another be enameled wire tail head notch 2-2.

In use, first enameled wire 3 is started and is caught in the L-type fluting of low-voltage framework 2-1 during machine automatic winding, Start coiling, coiling is completed, and enameled wire tail head is caught in automatically in the L-type fluting of low-voltage framework 2-2, and cuts enameled wire 2, is completed One winding process, realizes automaton coiling, has saved cost, improve production efficiency.

Claims (1)

1. one kind can fix the low-voltage framework of tail head, including low-voltage framework automatically, it is characterised in that: in the enamel-cover of low-voltage framework Line plays tail first speed circle (1), and along the circumferential direction there are two L-type notch (2), long-armed opening width and enameled wire (3) of L-type notch (2) Overall diameter is identical, one of them of notch (2) be enameled wire start notch (2-1), another be enameled wire tail head notch (2- 2).
