Abstract
The utility model provides an E-pole pin, wherein a cavity is arranged inside the E-pole pin. The utility model further provides an environment-friendly British plug which comprises a plug body, the E-pole pin, an L-pole pin and an N-pole pin are arranged on the plug body, and the cavity is arranged in the E-pole pin. The E-pole pin and the environment-friendly British plug using the same are copper-materials-saving, energy-saving and environment-friendly.
Description
Technical field
The utility model relates to the improvement of a kind of plug and correlated parts.
Background technology
Plug all will be used this thing on nearly all electrical equipment.In the plug, commonly three-pin plug is as shown in Figure 5, has band L utmost point pin, the N utmost point pin of delta arrangement, the plug of E utmost point pin in other words.
Pin all is the copper product manufacturing of adopting good conductivity basically; In some foreign standards such as British Standard; E utmost point pin is very big; Often many greatly than L utmost point pin, N utmost point pin, but in use the E utmost point is that ground wire is not but born main electrical functions, and what E utmost point pin played in fact is the fixedly effect of whole plug.The E utmost point pin of prior art like Fig. 1, shown in 2, is that the cutting of solid copper material forms, and this process materials coefficient of losses is high, and needs the amount of copper very big.And the price of copper is more and more expensive, and natural copper ore resource is exploited fewer and fewer.
Summary of the invention
Waste copper product in order to overcome existing plug, the deficiency of not environmental protection, the utility model provides a kind of E utmost point pin and uses the English plug of this E utmost point pin.
The technical scheme that the utility model solves its technical problem is: a kind of E utmost point pin is provided with cavity in the described E utmost point pin.Said E utmost point pin can adopt the Sheet Metal Forming Technology manufacturing, forms cavity.
Further, described E utmost point pin comprises the E utmost point pin shell of a hollow, and said E utmost point pin shell end openings and opening part are installed with a lock dog, and E utmost point pin shell and lock dog surround said cavity.Said E utmost point pin shell can adopt copper sheet to strike out hollow element, and single-ended opening, and the said mode of setting firmly can be selected welding for use, and prior art such as press.
Further, said lock dog plug is located in the E utmost point pin shell end openings, can increase ruggedized constructions such as projection, groove at corresponding lock dog or E utmost point pin shell end openings place in order to improve fixed effect.
Further, laterally be provided with the wire guide that passes E utmost point pin shell and lock dog on the described E utmost point pin, also be provided with the retaining thread hole of conducting wire guide and lock dog terminal surface on the described lock dog.For end can better connect copper conductor energising, so wire guide and retaining thread hole are set in order to the fixed copper lead, said retaining thread hole fixes the copper conductor that penetrates wire guide in order to be screwed into hold-down screw.
The utility model also comprises the English plug of a kind of environmental protection, comprises a header body, and described header body is provided with E utmost point pin, L utmost point pin, N utmost point pin, is provided with cavity in the described E utmost point pin.
Said header body can be an integral structure, can be to be divided into the header body that sheet up and down or other forms are combined into.
Further, described E utmost point pin comprises the E utmost point pin shell of a hollow, and said E utmost point pin shell end openings and opening part are installed with a lock dog, and E utmost point pin shell and lock dog surround said cavity.
Further, said lock dog plug is located in the E utmost point pin shell end openings.
Further, laterally be provided with the wire guide that passes E utmost point pin shell and lock dog on the described E utmost point pin, also be provided with the retaining thread hole of conducting wire guide and lock dog terminal surface on the described lock dog.
Further, also have cavity in described L utmost point pin and the N utmost point pin, save material, energy-conserving and environment-protective for advancing one.Said L utmost point pin and N utmost point pin can adopt and E utmost point pin similar design.
The utility model is consistent with the English plug and the E utmost point pin of prior art in use.
The beneficial effect of the utility model is: 1, save copper product, energy-conserving and environment-protective.2, impact style manufacturing, one-shot forming is enhanced productivity.3, the minimizing of copper material use amount makes with can using the better copper material of mechanical property and electric property under the cost, and the surface smoothness that has increased pin has promptly improved contact performance.
