Abstract
The utility model discloses a drainage reinforcement device of the injection material of plug conductive terminator insulation layer, in which the conductive terminator of plug comprises the coated and bare sections of the connector assembly. The bare section is in the formation of a wide front section and a narrow rear section. The edge of the front end of the coated section is more convex or in flush relative to the narrow rear section, which is also provided with an injection gate of a depressed shallow slot. The narrow rear section of the utility model is in penetration of an injection perforation, which is coated with an insulation layer. The initial material pouring of the insulation layer can be provided on the injection gate of the depressed shallow slot. The edge of the injection perforation is extended with a drainage reinforcement channel for drainage. When the pouring is provided, the injection material flowed to the injection perforation is flowed outward from the drainage reinforcement channel of the narrow rear section, so that the injection material can be appropriately vented to facilitate the smooth flowing and gas discharge. Therefore, after the insulation layer of the narrow rear section is formed, the thickness of the membrane is levelled with uniformity.
Description
Technical field
The utility model relates to a kind of electric power transfer plug, refers to a kind of plug conducting terminal insulating barrier ejection casting material drainage reinforcing device especially.
Background technology
Electric power provides daily life and industrial many facilities, engages and conduct current to electrical equipment or appliances with socket and the transmission of electric power mainly is mat one wire and plug.
When the plug conducting terminal contacts with power supply, often get loose owing to plug, so that the plug conducting terminal is exposed, make the user that the danger of electric shock be arranged, for avoiding this danger, many advanced countries, how to coat an insulating barrier in plug conducting terminal surfaces part position, with the possibility of reduction user electric shock, thereby form except conduction, have the standard and the specification on safe insulation surface concurrently.
This insulating barrier material is the insulation plastic cement, when the metallic conduction terminal is made, ejection formation and coating, and the coating kenel of ejection formation like this, because conducting terminal is smooth metal, so the insulation plastic rubber ejaculate molding of unlike material is when coating, and Chang Yin is grabbing that degree is not enough, tack is relatively poor and is being difficult to the location, therefore insulating barrier slides easily, even causes coming off; Then replying the metallic conduction terminal when insulating barrier comes off again exposes and easy precarious position of getting an electric shock.
The applicant once had an improvement structure, promptly between conducting terminal two planes of symmetry, be provided with material feeding perforation, form a solid space by this material feeding perforation, after can penetrating by inlet for the insulating barrier ejection casting material, have for the metal of depression section and grabbing the intensity that reach set, and this material feeding perforation provides ejection casting material to inject, make depression sections two carry out packing job simultaneously, shorten ejection casting material and inject stroke, help ejection casting material and be shaped.But discovery at the material feeding punch position, be easy to generate a dry and hard flaw (mostly being scrobicula), thereby it is attractive in appearance at surface of insulating layer to influence conducting terminal after doing when the ejection casting material filling and bringing together admittedly.
So, this creator continues again and researches and develops a kind of plug conducting terminal insulating barrier ejection casting material drainage system, this plug conducting terminal 1 (seeing also shown in Figure 1) comprises that a plug pedestal coats section 11 and naked section 12, and this naked section 12 forms front wide-section 121 and rear narrow-section 122; And coat the section comparatively protruding height of the relative rear narrow-section 122 of 11 front ends or concordant, a coating section front-end edge is established a depression shallow slot and is annotated cast gate 111; Its rear narrow-section 122 runs through material feeding perforation 123, and rear narrow-section 122 coats an insulating barrier before finished product, forms the depression shallow slot and annotates cast gate 111 and can provide the initial ejection casting material notes of insulating barrier to water.
Yet, in actual production manufacturing process, this creator finds again, notes water process, annotate the ejection casting material channel of cast gate 111 by the depression shallow slot to material feeding perforation 123, ejection casting material closely promptly falls into material feeding perforation 123 in crossing, and other surperficial air of metallic conduction terminal can't evenly squeeze, thereby can't evenly be spread; And the cross flow ejection casting material of metallic conduction terminal surfaces can't obtain one and lead pipeline off and slightly crowded, make that ejection casting material is shaped after, the uniformity and the evenness of thickness are affected.
The utility model content
The purpose of this utility model is to provide a kind of make insulating barrier annotate the watering smooth and easy and uniform film thickness of drainage, smooth plug conducting terminal insulating barrier ejection casting material drainage reinforcing device.
For achieving the above object, solution of the present utility model is:
Plug conducting terminal insulating barrier ejection casting material drainage reinforcing device, this plug conducting terminal comprise that a plug pedestal coats section and naked section, and this naked section forms front wide-section and two sections differences of rear narrow-section; And coat the section front-end edge and establish a depression shallow slot notes cast gate; Its rear narrow-section runs through material feeding perforation, and rear narrow-section coats an insulating barrier, and the depression shallow slot is annotated cast gate can provide the initial ejection casting material drainage notes of insulating barrier to water; The peritreme extension one of its material feeding perforation is gone into the ejection casting material drainage in the drainage reinforcement road of material feeding perforation.
After adopting said structure, provide and annotate when watering, ejection casting material flow to the material feeding perforation, and by the drainage reinforcement road of rear narrow-section outwards flowing, other surperficial air of metallic conduction terminal can evenly squeeze and obtain even diffusion; And the cross flow ejection casting material of metallic conduction terminal surfaces obtains one and leads pipeline off and no longer crowded, thereby after the rear narrow-section insulating barrier is shaped, uniform film thickness, smooth; After ejection casting material was filled up, the depression shallow slot that coats the section front-end edge was annotated the formed body in the drainage reinforcement road of cast gate and material feeding perforation peritreme, compound hardness and the plastic cement pliability that has metal body concurrently, thereby the bending resistance anti-crawl agentdefiection characteristic of increase metallic conduction terminal.
