Description

Ignition coil's elementary skeleton

Technical Field

The utility model relates to a primary framework of an ignition coil.

Background

Typically, the ignition coil has two sets of coils inside, a primary coil and a secondary coil. The primary coil is made of a thick enameled wire, and the primary enameled wire is wound on the primary framework through a winding machine and a winding jig.

In the prior art, the primary bobbin has a structure as shown in fig. 1, two ends of a bobbin 101 of a square tube body are provided with a limiting convex plate 102 for limiting edges of two ends of a winding, and the limiting convex plate 102 is provided with two slots 10 for passing a wire. Such a structure has the following disadvantages: 1. during winding, a fixed point needs to be found on the winding jig to fix the primary enameled wire, so that the primary enameled wire is wasted; 2. after the primary coil is wound, the inlet and outlet wires of the enameled wire of the primary coil cannot be fixed, and an insulating adhesive tape needs to be wound on the primary wire group for fixing, so that the manufacturing cost is increased; 3. because the incoming and outgoing wires of the primary coil cannot be fixed, the length of the remaining wire of the copper wire is not accurate enough, the labor amount needs to be increased by adding the action of cutting the short wire end in the subsequent process, and the cut wire end is easy to be left in the product, so that the product has quality hidden troubles such as discharge, breakdown and the like.

SUMMERY OF THE UTILITY MODEL

In order to solve the above drawbacks, the present invention provides a primary bobbin for an ignition coil, which facilitates winding, reduces material cost, and simplifies manufacturing processes. In order to solve the technical problem, the utility model adopts the technical scheme that the primary framework of the ignition coil comprises a framework of a square pipe body, and is characterized in that two outer side walls opposite to the upper end of the framework are fixedly provided with winding posts.

The utility model has the advantages that the winding post is arranged to wind the primary enameled wire on the winding post at one side of the primary framework by winding a circle of the primary enameled wire on the winding post at one side of the primary framework to fix the incoming wire of the primary enameled wire, the outgoing wire of the primary enameled wire is fixed by winding a circle of the winding post at the other side of the primary framework after the winding is finished, the primary enameled wire is fixed, the wire can be cut according to the length requirement of the remaining wire, the primary framework with the cut wire can be taken down from the winding jig to flow to the next process, the primary enameled wire is fixed without winding an insulating tape on the primary winding, the material is saved, the cost is reduced, the condition of the dispersion of the primary winding is avoided, the length of the remaining wire is controllable, the waste of the primary enameled wire is avoided, the length of the remaining wire is accurate, the wire cutting in the subsequent process is avoided, thereby avoiding the cut thread end from being left in the product to cause the product to have quality hidden troubles such as discharge, breakdown and the like.

In an improvement, the winding post is in a T-shaped configuration. The condition that the primary winding scatters wires due to the fact that the primary enameled wires slide out of the winding posts is avoided.

In an improved mode, the outer wall of the framework of the square pipe body is set to be an arc surface. Make the outer wall laminating of elementary enameled wire and elementary skeleton inseparabler, reduce the probability of scattered line in the time of the wire winding simultaneously, improve the performance of product.

And the side wall of the inner cavity of the framework of the square pipe body is provided with a convex rib. The inner chamber of skeleton is used for assembling the iron core, and the lateral wall is equipped with the bead and makes the iron core assembly tighter, avoids the iron core to rock in elementary skeleton to improve the performance of product.

Furthermore, chamfers are arranged at two ends of the convex edge. The chamfer is convenient for the iron core to be arranged in and has a guiding function.

Of course, it is not necessary for any product in which the utility model is practiced to achieve all of the above-described advantages at the same time.

Detailed Description

Referring to fig. 2-3, a specific configuration of the present invention is reflected. The primary framework of the ignition coil comprises a framework 1 of a square pipe body, limiting convex plates 7 for limiting edges of two ends of a winding are arranged at two ends of the framework 1, and a winding post 2 is fixedly arranged on two outer side walls opposite to the upper end of the framework 1 respectively. During the kinking, only need earlier twine primary enameled wire 8 round on kinking post 2 of primary skeleton one side, the inlet wire of fixed primary enameled wire, alright directly wind on primary skeleton, only need twine the round on kinking post 2 of primary skeleton opposite side after the wire winding, can fix the play line of primary enameled wire 8, avoided the condition that primary winding looses the line. Meanwhile, the wire can be cut according to the length requirement of the wire, and the primary framework of the cut wire can be taken down from the winding jig and can flow to the next procedure.

In this example, the winding post 2 has a T-shaped configuration. The protruding part of the outer end of the winding post 2 prevents the primary enameled wire from slipping out of the winding post, so that the primary winding is prevented from being scattered.
