Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, electric connector generally includes socket 1 and plug 2, the isolation protective design to avoid insterting by mistake of this electric connector is characterized in that: be provided with division board 101 in the cavity of described socket 1, division board 101 is provided with anti-anti-inserted groove 102; An end that inserts socket 1 on the described plug 2 is provided with the division board slot 201 that is complementary with division board 101.
Also be provided with on the inwall of described socket 1 and be used for fixing the spacing protruding stupefied 103 of plug 2, the outer wall of plug 2 is provided with and the spacing protruding stupefied 103 spacing tongues 202 that are complementary.Described anti-anti-inserted groove 102 is arranged on the position except that central authorities on the division board 101.Described anti-anti-inserted groove 102 is provided with one at least.
Electric connector with two cores is an example below, and embodiment of the present utility model is illustrated.
As shown in Figure 5 and Figure 6, the centre position is provided with a division board 101 that is used for the cable isolation in socket 1 cavity, and the left end of division board 101 is provided with an anti-anti-inserted groove 102, and socket 1 inwall is provided with two spacing protruding stupefied 103; The centre position of plug 2 is provided with the division board slot 201 that a big or small length all adapts with division board 101, the side of plug 2 be provided with two with spacing protruding stupefied 103 big or small length adapt 202.
The difference of Fig. 7 and Fig. 5 is: the left end of division board 101 is provided with an anti-anti-inserted groove 102 that aperture efficiency is bigger.The difference of Fig. 7 and Fig. 5 is: the division board slot 201 that the centre position of plug 2 is provided with is correspondingly opening increase also.
