In the utility model preferred embodiment, described male plug is also connected with power line, be provided with 4 wires in power line, and each wire is inserted in cylindrical hole respectively.

In the utility model preferred embodiment, on described female plug sheet, corresponding lead quantity is provided with 4 standard inserted sheets.

In the utility model preferred embodiment, one end that male plug embeds mother socket is provided with boss, and on mother socket, corresponding lug boss position is provided with embedding shell fragment.

The beneficial effects of the utility model are: the fast plug advantage of small area analysis, small voltage can be applied in the instrument of big current, large voltage by the utility model, not only realize patching fast of the combination hub of big current, greatly voltage, and male and female socket all meets high-level safety standard requirements.

Embodiment

Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model embodiment comprises:

The quick plug-in unit of a kind of four-core big current, comprising: male plug 2 and mother socket 4, male plug 2 embeds in mother socket 4, and one end that male plug 2 embeds mother socket 4 is provided with boss 5, and on mother socket 4, corresponding boss 5 position is provided with and embeds shell fragment 3.

Boss 5 on male plug 2 is inducted into mother socket 4 by embedding shell fragment 3, and allows boss 5 snap into corresponding position by rotating, and reaches the object of locking, keeps closely cooperating of male and female socket 4, fully contact when ensureing energising.

As shown in Figures 2 and 3, male plug 2 embeds mother socket 4 simultaneously, and male plug 2 fully contacts with female plug sheet 7 with the male plug pin 6 in mother socket 4, and tolerance pin and female plug sheet 7 all adopt the form of injection moulding to be injection-moulded in inside male and female socket.

Wherein, male plug pin 6 one end is needle-like, and the other end is that plug wire is with cylindrical poroid.Female plug sheet 7 one end is standard inserted sheet 8, and the other end then contacts with the needle-like end of male plug pin 6.

Described male plug 2 is also connected with power line 1, be provided with 4 wires in power line 1, and each wire is inserted in cylindrical hole respectively.On described female plug sheet 7, corresponding lead quantity is provided with 4 standard inserted sheets 8.

This plug-in unit is more than general plug single line, can be widely used in different purposes and select.

As shown in Figure 4 and Figure 5, in order to meet, must to meet creepage distance for voltage in the scope of 50-130V be 8mm, electric clearance is the requirement of 5mm, male plug pin 6 and female plug sheet 7 are injected into inside housing according to certain position respectively, male plug pin 6 and female plug sheet 7 is effectively controlled to the distance patching plane by plastic casing, all control in the scope of 5-10mm, make male plug 2 be less than or equal to 3mm with the width of the cannelure 9 of mother socket 4 simultaneously, thus ensure its fail safe contacted.

The fast plug advantage of small area analysis, small voltage can be applied in the instrument of big current, large voltage by the utility model, not only realize patching fast of the combination hub of big current, greatly voltage, and male and female socket all meets high-level safety standard requirements.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
