Description

Power connector

[technical field]

The relevant a kind of power connector of the utility model refers in particular to a kind of power connector that improves inner base frame that has.

[background technology]

General power connector is in living at home, and user demand promotes along with the electrical equipment diversification, and the power supply of various electrical equipment mainly is to transmit through electric wire and power connector, and therefore various power connectors also receive the further attention of producing with the developer.General appliance plug has two utmost point conducting terminals or three utmost point conducting terminals; When putting the line operation, earlier heart yearn is placed in the trunking of conducting terminal, again the conducting terminal end is being pressed the heart yearn of electric wire with terminal press entrainment kenel; Then conducting terminal is inserted in inner base frame; Form conducting terminal and electric wire with this secondary operations mode and be arranged at inner base frame and form preliminary semi-finished product after fixing, again it is inserted mould, accomplish one through ejection formation and have the shape of plug box.Three-electrode power plug is in the use because of than the tool fail safe, so be widely used in the general electrical equipment.

A kind of power connector is disclosed like Chinese utility model patent and announces shown in CN2153866Y number; It has disclosed a kind of power connector; It comprises inner base frame, earth terminal and positive and negative electrode terminal; Wherein be open state, come inlay card positive and negative electrode terminal through two parallel lugs and respective bump with the corresponding respectively through hole outside of positive and negative electrode terminal; Because the through hole outside is the convenience of assembling after open state causes the positive and negative electrode terminal to be pegged graft and retain strength is stable inadequately and poor stability; Only rely on simultaneously the parallel lug terminal and insecure that locks, be easy to generate tongue piece projection when getting loose phenomenon and moulding and cause the fraction defective increase because of from top to bottom casting pressure comes off easily.Therefore, necessary power connector is improved to solve above-mentioned defective of the prior art.

In sum, be necessary to provide a kind of improved power connector to solve the problems referred to above.

[utility model content]

The main purpose of the utility model is to provide a kind of and has the power connector that improves inner base frame, in case not-go-end gets loose and strengthens cooperating, improves the fail safe of power connector.

For realizing above-mentioned purpose; The utility model power connector adopts following technical scheme: a kind of power connector; It comprises the inner base frame with jack and is contained in the plurality of conductive terminals in the jack, and said inner base frame comprises the barrel that main part and autonomous body rear end face extend back, and said jack runs through the grab that is provided with fixed terminal in main part and barrel and the jack; Said barrel is not sealed, and said grab is formed with barrel between the barrel opening and separates the space.

Compared with prior art; The utlity model has following beneficial effect: grab and shell portion are left; Thereby leave between grab and the barrel and separate the space; The plastic cement molten mass can be penetrated into the top from grab below, the plastic cement molten mass permeates the stamping press to grab from top to bottom when having avoided advancing glue, thereby preventing that the grab downwarping from cooperating with earth terminal comes off.
