Description

Electric connector

[technical field]

The utility model relates in particular to a kind of holding structure of electric connector terminal about a kind of electric connector.

[background technology]

Existing electric connector generally includes shell, body, is contained in the plurality of terminals of body.Wherein body comprises base portion and the hyoplastron that is extended to form forward by base portion, base portion is provided with through hole, hyoplastron is provided with some conduits, and terminal comprises the horizontal part that is installed on the hyoplastron conduit, extends back and the vertical portion that vertically is bent to form, prolong the weld part that terminal and other assemblies are welded that forms from the vertical portion from horizontal part.

The part electric connector many row's terminals are set, and the vertical portion of terminal is arranged side by side, then the vertical portion of terminal needs constriction so that the vertical portion of many butts to be set in the confined space.Then the horizontal part width of terminal is provided with a tearing port at horizontal part and vertical portion intersection usually greater than the vertical portion, and makes the part that horizontal part is wider than the vertical portion continue horizontal-extending, forms the operating portion for installation personnel operation terminal.At terminal during to the body plug-in mounting, installation personnel is by the operating portion of press terminal horizontal part end, terminal is pushed in body, then the power that is subjected to of terminal is not the center line that acts on terminal, but be partial to a side, then there is turning moment in terminal when being pressed into body, terminal is after being installed on body, may be amesiality on horizontal plane, produce with the vertical inner wall of the conduit of hyoplastron and to interfere, then electric connector with dock electric connector and connects after, terminal is possible because of this interference, can't return to the normal position, the bad contact when causing use next time.

In addition, extend to form the elastic contact part of a warpage usually forward at the horizontal part of terminal, the height of this elastic contact part is provided with the interference part of width greater than elastic contact part much larger than the horizontal part of terminal on the horizontal part.Because interfere the hole to cooperate with the interference part of terminal, so it is highly lower, elastic contact part can't pass through from interfering the hole, therefore, body is provided with a perforation that width is less but highly higher above being arranged on usually and interfering the hole, this the perforation with width more greatly but highly lower installing hole be communicated with, the two common composition roughly is the installing hole of convex shape.Tilt when operating personnel install with terminal with elastic contact part higher so as by perforation, the interference part is lower so that install to body by the mode of interfering the hole, after terminal is installed on body, angular deflection in the time of can be because of preliminary the installation causes terminal warpage up and down, highly differs.

In sum, necessaryly provide a kind of improved electric connector identical to guarantee the height after terminal is installed, and terminal normotopia in the horizontal direction.

[utility model content]

Main purpose of the present utility model is to provide a kind of electric connector, and its terminal has consistency preferably after being mounted to body.

For reaching aforementioned purpose, the utility model adopts following technical scheme: a kind of electric connector, comprise the material that insulate body, be contained in the plurality of conductive terminals of body, body comprises base portion that roughly is cuboid and the hyoplastron that extends to form forward from base portion, wherein the base portion upper surface is provided with the depressed part that caves inward, be respectively arranged with antetheca and rear wall before and after the depressed part, antetheca and rear wall are provided with the installing hole of mounting terminal, and this installing hole passes described depressed part; Electric connector also is provided with one and is installed on depressed part to cooperate with depressed part terminal clamping and fixing fixing piece.

Compare with prior art, fixing piece clamping terminal of the present utility model guarantees the location of terminal in body, guarantees that the height after terminal is fixed is identical, and realizes terminal normotopia in the horizontal direction.
