Abstract

The invention relates to a terminal and an insulating layer structure coated on the terminal, comprising a terminal; an insulating layer is arranged on the outer edge of the terminal; in the invention, the section of the terminal, which is coated with the insulating layer, forms a shape from wideness to constringency from back to front, and the thickness of the insulating layer coated on the outer edge of the terminal is gradually thick from back to front, thus leading the terminal after coated with the insulating layer to form a straight shape, and the requirement of coating the insulating layer on the terminal and the balance among the rigidity of the terminal are met, and safety test is met.

Description

The insulating layer conformation of terminal and coating thereof

Technical field

The present invention relates to a kind of terminal structure, particularly the insulating layer conformation that coats on the terminal.

Background technology

General daily life and industrial operation, the use of electrical equipment or appliances, the power source of its alternating current mainly is to rely on a wire and plug to engage with socket, and conducts current to electrical equipment or appliances.And described wire and plug mainly is to be provided with two-terminal or to comprise an earth terminal in addition.The integral manufacturing of described wire and plug, mainly be with the stable internal frame that is located at of aforementioned terminal, rely on described internal frame stable after, again with the shell injection molding of a terminal part with plug, terminal is then naked to go out a part as connecing the usefulness of merging into conduction with socket.And, and form the danger that the user gets an electric shock because the described naked part that goes out exposes easily with the socket engaging portion, therefore many countries stipulate that the naked part that goes out of described terminal need be provided with at a section portion coated insulation layer, gets an electric shock to prevent the user.

See also Fig. 1 (is example with the circular terminal), the coated state of the terminal of prior art 11 and insulating barrier (described Fig. 1 be a terminal coated insulation layer state not as yet) generally speaking is that terminal 1 is designed to from top to bottom is flat.Yet its problem is, under the specification that a certain plug is made, in order to consider the easiness of injection molding, as far as possible the external diameter of terminal 1 is set to lessly, makes that in mould injecting plastic rubber material has a relatively large circulation to be convenient to production operation with coating the path, but the external diameter of described terminal 1 is if be provided with less, just make the metal rigidity deficiency of terminal 1 easily relatively, therefore under the safety standard of appliance plug testing drum, be difficult to by check.On the other hand, if will keep the external diameter of described terminal 1, then the thickness calibration of described insulating barrier will be reduced relatively, but this thickness reduces the difficulty that causes the ejaculation operation to be shaped again.Promptly easily in the terminal quality defect that produces starved of plastic rubber material filling, promptly, lose the quality defects of insulation function because insulating layer thickness is spent and thinly caused the metal of terminal 1 to expose.

See also (is example with flat solid terminal) shown in Fig. 2 A and Fig. 2 B, described prior art two is more or less the same with prior art one, and outward appearance slightly variant be flat.And described Fig. 2 A and its outline of terminal 1A of Fig. 2 B also are one from top to bottom to become flat.And the corresponding insulating barrier 11 that coats also is one from top to bottom to become flat, therefore with aforementioned prior art one the same problem is arranged equally also.

Summary of the invention

At the deficiencies in the prior art, the objective of the invention is to: the insulating layer conformation of a kind of terminal and coating thereof is provided, take into account that insulating barrier coats satisfy and the terminal rigidity between balance.

The present invention solves the employed technological means of previous problem, it mainly is the insulating layer conformation of a kind of terminal of design and coating thereof, comprise a terminal, described terminal outer rim is provided with an insulating barrier, and the present invention mainly is the section portion of described terminal coated insulation layer, by after form forward one broad to restraining shape, and the thickness of insulating layer that described terminal outer rim is coated, relatively by after gradually thick forward, make described terminal behind the coated insulation layer, form a flat.

Again, the present invention goes for the terminal of various kenels, for example at solid cylindrical, solid flat shape, hollow cylinder, hollow pancake terminal etc.

Compared with prior art, the beneficial effect that the present invention has is: though make terminal body have the less periphery of a part, the back outward appearance that coats at insulating barrier still presents straight, terminal body still has enough standard compliant rigidity at the position that needs carry out the rigidity test, can meet safety standard.
