AI Technical Summary
When making the plug, slight displacement or deformation may occur during the molding process between the insulating layer and the inner frame, resulting in mismatch with the mold when the insulating layer is sprayed and formed, resulting in gaps, which will lead to the insulating layer oozing and lifting along the extended edges, affecting the durability quality and safety of the product.
A terminal rod body and insulating layer cladding structure is designed, by covering the insulating layer at the outer edges of the oblique and straight edges, and filling the oblique side at the converging end of the insulating layer to form a flush flat part to prevent the insulating layer from rising up.
Effectively avoid or reduce the lifting of the insulating layer, improve the durability of the product and the stability of the clamping and coating, and ensure the safety of the insulating layer.

Abstract
Description
Technical Field
[0001] The utility model relates to an electrical connection element, in particular to a terminal rod body and an insulating layer covering structure. Background Art
[0002] See also Figure 7 and Figure 8 As shown, a state of a terminal rod body 3 combined with an inner frame is shown. Currently, when manufacturing plugs in the industry, for the front-opening plug terminal 3, a so-called "insulating layer" is provided to ensure the correct position arrangement of the contact pieces, to insulate the respective contact sections of the two terminals of a plug from each other, and to take into account safety considerations and other factors.
[0003] In the manufacture of the insulating layer, some designers adopt the method of integrally forming the insulating layer and the inner frame by injection molding. When the terminal rod body 3 is stamped, due to a slight difference in force or positioning, its outer edge may be slightly displaced or deformed (although it is still within the tolerance acceptable in safety specifications). However, this slight displacement or deformation may cause Figure 5 As shown, when the rubber material of the insulating layer 4 is injection molded, a slight gap is generated between the mold and the rubber material, and the rubber material may penetrate through the slight gap and form a film as shown in FIG. Figure 5 and Figure 6 The extended edge 41 is shown.
[0004] Since the extended edge 41 is partially protruding relative to the terminal rod body 3 and is caused by abnormal seepage, if the grip and covering properties are insufficient, it is easy to cause warping and the so-called "burr" phenomenon due to frequent use, and it is easy to cause partial peeling of the insulating layer 4, reducing the durability of the product and affecting the safety of the insulating layer. Utility Model Content

[0006] The utility model provides a terminal rod body and an insulating layer covering structure, comprising a terminal rod body, the terminal rod body comprising a contact section that can be inserted into a socket, two sides of the terminal rod body are both transformed from a bevel to a straight side in a section, the outer edges of the bevel and the straight side are covered with an insulating layer, and the insulating layer gradually converges toward the contact section, and the convergent end is filled into the side of the bevel to form a flat portion flush with the terminal rod body after filling.
[0007] The utility model can avoid or reduce the so-called "burrs" formed by the lifting of the insulating layer, thereby improving the durability of the product and facilitating the stability of gripping and covering. BRIEF DESCRIPTION OF THE DRAWINGS
