Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The utility model provides a kind of anti-short circuit female plug seat, comprise shield shell, insulating base and terminal, described insulating base is sheathed in the described shield shell, and described terminal then is connected in the described insulating base, and the end face of described insulating base is provided with and the corresponding groove of described terminal.

Below in conjunction with specific embodiment specific implementation of the present utility model is described in detail.

Shown in Fig. 1～3, a kind of anti-short circuit female plug seat 1 comprises shield shell 11, insulating base 13 and terminal 12, and insulating base 13 is enclosed within the

shield shell

11, and 12 of terminals are fixed in the insulating base 13, thereby constitute whole female plug seat 1.

Shield shell 11 is a hollow body, and its front and back end connects mutually, and like this, insulating base 13 just can insert shield shell 11.The both sides of shield shell 11 are respectively equipped with draw-in groove 111, be used for blocking the insulating base 13 that

inserts shield shell

11, and 111 places are provided with follow block 112 at draw-in groove, and this follow block 112 can prop up the insulating base 13 that inserts in the shield shell 11, and it is more firm to make that insulating base 13 connects in shielding draw-in groove 111; Front end at shield shell 11 is provided with a flap 113, and this flap 113 can press on the insulating base 13 that inserts in the shield shell 11, makes insulating base 13 can not come off from shield shell 11 easily.

Insulating base 13 comprises stick 131 and dull and stereotyped 132, stick 131 and dull and stereotyped 132 is an one, be provided with the fixture block 1311 that matches with the draw-in groove 111 of shield shell 11 in the both sides of stick 131, dull and stereotyped 132 is hollow, and terminal 12 is fixedly connected in the flat board 132 of insulating base 13.

After insulating base 13 inserted shield shells 11, fixture block 1311 was enclosed within the draw-in groove 111, and follow block 112 presses on

fixture block

1311, and 113 of flaps press on the end of stick 131, thereby make being connected in the shield shell 11 that insulating base 13 can be firm.

In order to make the terminal head 121 of the terminal 12 be fixedly connected on insulating base 13 inside can not expose or the end face of concordant insulating base 13, avoid the terminal head 121 of terminal 12 and extraneous metal easily to come in contact, thereby cause the phenomenon of short circuit, in the present embodiment, end at the flat board 132 of insulating base 13 offers groove 1321, the position of this groove 1321 is corresponding in dull and stereotyped 132 position with terminal 12, and quantity is consistent with the quantity of terminal 12, this groove 1321 is communicated with dull and stereotyped 132 inside, thereby make the terminal head 121 of terminal 12 to reveal from groove 1321, and can not come in contact by easy and extraneous metal, thereby cause short circuit phenomenon, and can guarantee female plug seat 1 when combining with other male plug 2, terminal 12 can with terminal 12 combinations in other male plug 2.
