Abstract
The invention relates to an electric connector comprising an insulation body, conductive terminals and a switch, wherein the conductive terminals are contained in the insulation body; the switch is arranged on the insulation body; the insulation body is provided with a splicing hole and an elastic arm which extends into the splicing hole and can move up and down under the resistance of a butting plug; the switch comprises a first fixed terminal, a second fixed terminal and a movable terminal, wherein the first fixed terminal and the second fixed terminal are separately arranged, the movable terminal is arranged on the elastic arm, the first fixed terminal and the second fixed terminal are respectively provided with welding pins which extend out of the insulation body, and the movable terminal is integrally suspended above the first fixed terminal and the second fixed terminal and can respectively contact with or separate from the first fixed terminal and the second fixed terminal by being driven by the elastic arm so that electrical switch-on or switch-off is formed between the first fixed terminal and the second fixed terminal by dint of the movable terminal. Therefore, when the movable terminal is in a disconnection state with the first fixed terminal and the second fixed terminal, the butting plug only bears the resisting force of the elastic arm and the conductive terminals, the insertion and withdrawal force on the butting plug is reduced, and the insertion and the withdrawal of the butting plug are more convenient.
Description
[technical field]
The relevant a kind of electric connector of the present invention relates in particular to a kind of electric connector with switch.
[background technology]
Prosperity along with science and technology; The use of electronic product is more prevalent; Make various different electric connector arise at the historic moment, generally speaking, when most electric connector inserts for corresponding plug; Can't detect this plug and whether be inserted into the location, thereby other controlled function can't be provided according to this.Therefore, present existing electric connector generally all is provided with the switch with detecting function.It is fixed terminal and movable terminal that the switch of these existing electric connectors is traditionally arranged to be two conducting terminals, and movable terminal can contact with fixed terminal or break off under the compressing of banjo.
The prior art relevant with this case can be announced a kind of electric connector of No. 2696165 announcement with reference to Chinese utility model patent; It comprises insulating body, flexible terminal, fixed terminal and binary signal terminal; Have the terminal containing slot of fixing aforementioned flexible terminal, fixed terminal, the elastic arm that supplies spliced eye that banjo inserts and extend in the spliced eye in the insulating body; Elastic arm and flexible terminal are adjacent; And flexible terminal is adjoining with fixed terminal again, and aforementioned binary signal terminal has the weld part that extends into the contact site in the spliced eye and extend insulating body, in the time of in banjo inserts spliced eye; Banjo promotes elastic arm and makes flexible terminal contact fixed terminal, thereby reaches the detecting effect of switch.Yet; This banjo at flexible terminal with before contact terminal contacts; Banjo goes out to receive outside the extruding force of binary signal terminal; Also having received the power that compresses of elastic arm self and the power of compressing of flexible terminal reaction promotion elastic arm is the indirect extruding force of flexible terminal, so that banjo is stressed excessive in the plug process, causes the user and plugs inconvenience.
Therefore, be necessary to provide a kind of structure improved electric connector that has, to overcome above-mentioned defective.
[summary of the invention]
The object of the present invention is to provide a kind of electric connector that improves contact engaging and separating force that has.
For reaching above-mentioned purpose; The present invention adopts following technical scheme: a kind of electric connector; It comprises: insulating body, be contained in the conducting terminal in the insulating body and be located at the switch on the insulating body; Insulating body is provided with in order to the spliced eye of accommodating banjo and extends in the spliced eye and also can compress elastic arm moving up and down down at banjo; Conducting terminal has the weld part that extends into the contact site in the spliced eye and extend insulating body; Said switch comprises first, second fixed terminal that branch is arranged and is located at the movable terminal on the elastic arm, and first, second fixed terminal is respectively equipped with the welding foot that extends insulating body, and said movable terminal integral body is suspended on the top of first, second fixed terminal; Said movable terminal can contact with first, second fixed terminal respectively or break off under the drive of elastic arm, forms and to electrically conduct or break off so that use movable terminal between first, second fixed terminal.
Compared with prior art; Electric connector of the present invention is used the top that movable terminal is located on the insulating body elastic arm and is suspended on first, second fixed terminal; Make that banjo only receives the power that compresses of elastic arm self and conducting terminal, and does not receive the indirect extrusion power of fixed terminal when movable terminal and first, second fixed terminal are in off-state; Reduced the contact engaging and separating force of banjo, made plug comparatively convenient.
