Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, refers to a kind of electric connector that is provided with pull bar and is used to connect and discharges the latch components of butt connector especially.

[background technology]

United States Patent (USP) the 5th, disclosed a kind of known electric connector for 564, No. 939, this electric connector is respectively equipped with latch components 22,22A on the two opposite side walls of its body 21, operating portion 23 is provided with cam 23-4, and this cam is positioned under the kink 22-4 of latch components 22,22A.When the operator pulls back the pull bar 23-8 of operating portion 23, the kink 22-4 of latch components release cam 23-4 also produces an outside active force, U type pawl 22-1 just outwards slides, to discharge butt connector, because operating portion 23 and latch components 22,22A is positioned at outside the body 21, so when external force is applied to it, they all are easy to suffer damage, when two or more connectors connect side by side, need to leave fully big space between per two connectors, will certainly cause negative effect to the design of the electronic system that includes connector like this, in addition, after the pulling force release that acts on the operating portion 23, latch components 22,22A applies operating portion 23 and makes it get back to the active force of initial position, but this active force is too little and operating portion 23 can not be back into initial position fully.In order to overcome above shortcoming, need provide a kind of novel electric connector.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector that is provided with pull bar and latch components, and this pull bar can pin or discharge butt connector, and can automatically revert to initial position after discharging butt connector.

In order to reach above-mentioned purpose, the electric connector that conforms to the utility model includes pedestal, insulating body, the lid that matches with pedestal, pull bar and latch components.Pedestal is provided with one and is provided with the sidewall of lengthwise first passage for its two opposite sides, and is provided with connection box in its front portion, and insulating body is assemblied among the interface frame, mating frame, and contains a plurality of terminals in wherein.Lid is provided with pair of sidewalls, and the lengthwise first passage corresponding to pedestal is provided with the lengthwise second channel to sidewall in its two opposite sides.Pull bar is provided with and places the external operating portion of pedestal and this and extend and place arm in first, second passage from the free end of operating portion, arm is provided with snap close release portion and from the inwardly outstanding elastic portion of extending of arm one in its free end, also is provided with the otch that extends into elastic portion on this arm and is installed on reinforced sheet in the respective cut.When butt connector docks with this electric connector, latch components matches with the tight butt connector that is connected with snap close release portion, when pulling back pull bar, snap close release portion pulling latch components makes butt connector separate with latch components, the reinforced sheet flexural deformation of elastic portion and pull bar simultaneously, when discharging pull bar, pull bar is back to initial position thereby flexure strip and reinforced sheet return back to the original-shape pulling.

Compared with prior art, the utlity model has following advantage: operating portion is in the outside of base and cover body, and arm is contained in the passage of pedestal, so just to arm and on latch spring better protection is provided; When pulling back pull bar, what snap close release portion pulling latch spring made separates with butt connector, elastic portion on the pull bar and sheet metal bending, and when discharging pull bar, elastic portion and sheet metal revert back to original state, thus pushing drawing rod is returned to initial position.
