The purpose of this utility model can be realized by following technical proposals: a kind of hexagonal volume for plug-in terminal
Code fool proof column, including coding unit and mounting portion；The coding unit is equipped with notch in one end of hexagonal column and hexagon prism；It is described
Mounting portion is set on the other end of hexagon prism, and mounting portion includes cylindrical body and elastic fin, and the cylindrical body setting is connected to
The other end face center of hexagon prism, symmetrically arranged using the axis of cylindrical body as center line on the side wall of cylindrical body to
Few two elastic fins, each elastic fin are connected on the side wall of cylindrical body and are obliquely installed towards hexagon prism direction.
Further, the cross section of the notch is the half that divides by long-diagonal of cross section of the hexagon prism, and
And the other end of the notch from one end end face of the hexagon prism along axis towards hexagon prism extends.Further, the notch
From one end end face of the hexagon prism along the half that axis extends to hexagon prism height.
Further, one end of the hexagon prism is also provided with hole, one end end face center of the hole from the hexagon prism
The other end along axis towards hexagon prism extends.
Further, the coding unit and mounting portion are connected.
Further, one end of the cylindrical body is connect with hexagon prism, the other end face edge chamfer of cylindrical body.
Compared with the prior art, the advantages of the utility model are: by notched hexagon prism and with elastic fin
Cylindrical body, which is linked together, constitutes hexagonal coding fool proof column, solves the function that routine encodes column and screw, washer combinations are got up.Band
The hexagon prism of notch can encode corresponding plug with socket for artificially defined, numerous identical when having
When plug-in terminal, so that it may guarantee correct with slotting between plug and socket.Realized by elastic fin with plug and insert
The assembly of the identification pin hole of seat end, good anti-drop effect.Injection molding can be used in the utility model, and realization produces in large quantity,
Have the advantages that low in cost, also solves the undesirable problem of salt fog performance of metal encoder column and screw, washer.When disassembly,
An easy hollow pole is only needed, it is safer compared to being dismantled originally using the screwdriver of cutting edge shape.

Fig. 2 is the schematic diagram that hexagonal encodes that fool proof column is installed on identification pin hole.
Fig. 3 is the schematic diagram for being equipped with the socket and plug of hexagonal coding fool proof column.
Fig. 4 is to encode the schematic diagram of fool proof column from disassembly hexagonal on identification pin hole.
Component mark is as follows in figure:
It is 1 coding unit, 101 notches, 102 holes, 2 mounting portions, 201 cylindrical bodies, 202 elastic fins, 3 plugs, 4 sockets, 5 hollow
Pole.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art
How ground understanding practices the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to Fig. 1, a kind of hexagonal coding fool proof column for plug-in terminal, including coding unit 1 and mounting portion 2；It is described
Coding unit 1 is equipped with notch 101 in one end of hexagonal column and hexagon prism；The mounting portion 2 is set to the other end of hexagon prism
On, mounting portion 2 includes cylindrical body 201 and elastic fin 202, and the cylindrical body 201 erects the other end end for being connected to hexagon prism
At least two elasticity are symmetrically arranged at face center on the side wall of cylindrical body 201 using the axis of cylindrical body 201 as center line
Fin 202, each elastic fin 202 are connected on the side wall of cylindrical body 201 and are obliquely installed towards hexagon prism direction.
The meaning that notch 101 is arranged is to encode the shape of coding unit 1 for artificially defined.The tool of notch 101
Shape may is that the cross section of the notch 101 is the half that divides by long-diagonal of cross section of the hexagon prism, and
Notch 101 from one end end face of the hexagon prism along axis towards hexagon prism the other end extend, more specifically, notch 101 from
One end end face of the hexagon prism is along the half that axis extends to hexagon prism height.
One end of the hexagon prism is also provided with hole 102, and the hole 102 is from one end end face center of the hexagon prism along axis
The other end of line towards hexagon prism extends.
One end of the cylindrical body 201 is connect with hexagon prism, the other end face edge chamfer of cylindrical body 201.
The coding unit 1 and mounting portion 2 are connected, and use plastic cement material, and adding for injection molding can be used in this way
Work technique carrys out one-pass molding, and realization produces in large quantity, has the advantages that low in cost.
In use, the mounting portion 2 of hexagonal coding fool proof column is inserted into towards plug or the identification pin hole of receptacle ends, make to pacify
Dress portion 2 passes through identification pin hole.During wearing identification pin hole, elastic fin 202 generate flexible deformation and towards cylindrical body 201
Side wall collapse；After passing through identification pin hole, elastic fin 202 restores original form, prevent hexagonal encodes fool proof column from edge
The opposite direction of direction of insertion is extracted, to realize hexagonal coding fool proof column and identify the installation of pin hole, referring to fig. 2.It installs
Hexagonal coding fool proof column can only substantially make it around own axis, according to the direction of notch 101 to corresponding plug
It is encoded with socket, guarantees that the coding of every a pair does not repeat, in this way when there is numerous identical plug-in terminals, so that it may protect
It demonstrate,proves correct with slotting between plug and socket.Fig. 4 installs the utility model hexagonal for the end of corresponding plug 3 and socket 4
Encode the schematic diagram of fool proof column.
When disassembly, the hollow pole 5 of cylindrical body 201 is slightly larger than using the diameter of a centre bore, is entangled cylindrical body
201 and elastic fin 202, so that elastic fin 202 is collapsed and be less than the aperture of identification pin hole, thus hexagonal can be encoded fool proof
Column is extracted along the opposite direction of direction of insertion.Fool proof column is encoded compared to original hexagonal, needs to be torn open with the screwdriver of cutting edge shape
It unloads, the utility model is safer.
It should be pointed out that can also have a variety of transformation and the implementation of remodeling for the utility model through absolutely proving
Scheme, it is not limited to the specific embodiment of above embodiment.Above-described embodiment as just the utility model explanation, and
It is not limitations of the present invention.In short, the protection scope of the utility model should include those for ordinary skill
It obviously converts or substitutes and retrofit for personnel, and be determined by the appended claims.
