Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides an arc-proof fool-proof connector which mainly comprises a first connecting piece 1 and a second connecting piece 2, wherein the first connecting piece 1 and the second connecting piece 2 are connected in an opposite-plug mode. The structure of specifically facilitating the opposite insertion is that the first connecting piece 1 is provided with a first connecting part 3, and the second connecting piece 2 is provided with a second connecting part 4 opposite inserted with the first connecting part 3. Since the structure of the insert includes two portions of the recess and the projection, in order to cooperatively explain other technical features of the first connector 1 and the second connector 2, the structure of the first connector 3 and the second connector 4 needs to be described in two cases.
Example 1:
As shown in fig. 1 to 6, when the first connecting portion 3 of the first connecting member 1 has a convex structure, the second connecting portion 4 of the second connecting member 2 has a corresponding concave structure.
The first connecting piece 1 is also internally provided with a male connecting end 5 coaxially arranged with the first connecting part 3, and the male connecting end 5 is connected at the top surface of the first connecting part 3 and integrally connected. The male connecting end 5 is composed of three male connecting monomers 6 which are distributed at intervals, and the three male connecting monomers 6 are distributed in an annular mode by taking the central shaft of the male connecting end 5 as a base point. Correspondingly, a female connecting end 7 coaxially arranged with the second connecting part 4 is also arranged inside the second connecting piece 2, and the female connecting end 7 is arranged at the bottom position of the second connecting part 4. The female connection end 7 is composed of three female connection monomers 8 which are distributed at intervals, and the three female connection monomers 8 are in one-to-one correspondence with the three male connection monomers 6 for opposite insertion.
After the male connection unit 6 and the female connection unit 8 are connected in a plugging manner, terminals for conducting electricity are assembled in the first connector 1 and the second connector 2, that is, after the first connector 1 and the second connector 2 are connected in a plugging manner, the internal terminals are synchronously contacted and conducted. At this time, the male connector 6 is provided with a slot 10, and the female connector 8 is provided with a terminal plug 11 protruding into the slot 10 to conduct electricity, and the terminal plug 11 and the terminal inside the second connector 2 are integrally formed. Structurally, the depth of the slot 10 is the distance between the first connector 1 and the second connector 2, that is, the terminal plug 11 is to be connected and electrically conductive in the slot 10, provided that the first connector 1 and the second connector 2 are completely closed. In order to avoid the situation that the terminal plugs 11 are inserted into the slots 10 to generate electric arcs, among the three terminal plugs 11, one terminal plug 11 has a longer length than the other two, the terminal plug 11 with a long enough length can be lifted in advance as a ground wire, thereby not only avoiding the situation of electric arcs, but also improving the use safety,
In order to prevent blind insertion during connection between the first connecting piece 1 and the second connecting piece 2 and prevent the identical structure of the first connecting piece 1 and the second connecting piece 2 from being damaged, a foolproof part 9 which is convenient for identifying the direction is arranged at the joint of the male connecting single body 6 and the female connecting single body 8, so that the internal structures of the first connecting piece 1 and the second connecting piece 2 can be better protected.
In addition, in order to improve the tightness of the connection between the first connector 1 and the second connector 2, a waterproof ring 15 is provided at the connection between the first connector 3 and the second connector 4 after the insertion, so that the waterproof effect of the connection between the two can be enhanced, and the waterproof ring 15 is sleeved outside the first connector 3.

Meanwhile, in order to facilitate the connection of the first connecting piece 1 and the second connecting piece 2 with an external mechanism, a first connector 12 which extends outwards to connect is arranged at one end of the first connecting piece 1 far away from the second connecting piece 2, and likewise, a second connector 13 which extends outwards to connect is arranged at one end of the second connecting piece 2 far away from the first connecting piece 1.
Example 2:
As shown in fig. 7 to 12, when the first connecting portion 3 of the first connecting member 1 has a concave structure, the second connecting portion 4 of the second connecting member 2 has a corresponding convex structure.
The difference between the present embodiment 2 and the embodiment 1 is that the first connecting portion 3 on the first connecting member 1 is in a concave structure, the male connecting end 5 coaxially arranged with the first connecting portion 3 is arranged at the bottom of the concave portion of the first connecting portion 3, correspondingly, the female connecting end 7 coaxially arranged with the second connecting portion 4 is arranged at the top of the convex portion, and the locking ring 14 is sleeved from the outer side of the second connecting member 2 and is locked with the outer side of the first connecting member 1 after rotating. The technical scheme of the present embodiment 2 has the same technical effects as those of embodiment 1.
Compared with the prior art, this technical scheme is when first connecting piece 1 and second connecting piece 2 are to inserting, and male end link 5 and female end link 7 junction have set up prevent slow-witted department 9, and the convenience leads to the inner structure to damage to the direction location when inserting to avoid blind the inserting, simultaneously, to the terminal plug 11 that is connected when inserting one of them longer, can insert in advance and electrically conduct and use as the ground wire, the phenomenon of electric arc appears when avoiding connecting.
