Main purpose of the present utility model is to propose a kind of power connection structure of dc source, prevents user will be different
The socket and plug mixed insertion of dc source, with protection circuit plate.
To achieve the above object, the utility model proposes dc source power connection structure, the power connection structure
Including：Jack for exporting dc source and cylindrical setting, and the plug for being adapted to and electrically connecting with jack, the plug
It is inserted into jack.Wherein, jack inwall is provided with an at least lug boss, the position in the outer wall respective protrusions portion of plug be provided with
The groove of lug boss adaptation, and axial direction of the groove along plug extends to the other end by one end of plug.
Preferably, the inwall of jack is provided with two lug bosses, and plug outer wall is corresponded provided with two and two lug boss positions
And the groove of shape adaptation.
Preferably, lug boss is the flange for being located at jack inwall and the axial direction setting along jack.
Preferably, the radial section semicircular in shape of flange.
Preferably, one end rounded setting of the flange close to the aperture of jack.
Technical solutions of the utility model are set between the plug outer wall that is adapted to it of jack inwall of Direct current power source socket
Put specific power connection structure.The power connection structure includes at least one lug boss, and the relative lug boss forms embedding
The groove of relation is connect, wherein, lug boss is located at jack inwall, groove plug outer wall.The power supply of the utility model dc source
Attachment structure can play foolproof function, user be prevented by the plug of different model and socket hybrid junction, so that protection circuit plate.Together
When, it can also increase the grafting intensity between power outlet and plug, it is to avoid plug surprisingly loosens, it is ensured that Electrical Safety.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to the structure shown in these accompanying drawings.
Fig. 1 is the structural representation of the socket of the power connection structure with the utility model part；
Fig. 2 is Fig. 1 stereogram；
Fig. 3 is the structural representation of the plug of the power connection structure with the utility model part；
Fig. 4 is Fig. 3 stereogram；
Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
The utility model proposes a kind of power connection structure of dc source.
Referring to figs. 1 to Fig. 4, Fig. 1 is the power supply connecting device of the power connection structure with the utility model dc source
Figure, 2 be Fig. 1 stereogram, and Fig. 3 is the structural representation of the plug of the power connection structure with the utility model part, Fig. 4
For Fig. 3 stereogram.
As shown in Fig. 2 and Fig. 4, a kind of power supply connecting device includes a socket 1 with insulation crust and suitable with it
The plug 2 matched somebody with somebody.The socket 1, which is provided with, to be used to export dc source and the jack 11 of cylindrical setting, the plug 2 and jack 11
It is adapted to and electrically connects, the plug 2 is inserted into jack 11.
Wherein, the power connection structure also includes：At least one is located at the lug boss 13 of jack inwall 12, and located at plug
Outer wall 21 and with each lug boss 13 corresponding groove 22 one by one.The lug boss 13 is located at jack inwall 12 and along jack 11
The flange that sets of axial direction, the axial direction of the groove 211 along plug 211 extend to the other end by one end of plug 2.Should
When the quantity of lug boss 211 set in explanation, jack inwall 12 is depending on particular situation, in the present embodiment, jack
Two lug bosses 131 and lug boss 132 are set on inwall 12, accordingly, the plug outer wall 21 being adapted to it set two grooves 221 with
Groove 222.User when in use, can quickly adjust the relative and lug boss of groove 221 and groove 222 by rotating plug 2
13 position, two lug bosses 131 and lug boss 132 are directed at groove 222 to two grooves 221, you can completed corresponding power supply and connected
