Description
Technical field
The utility model relates to a kind of error-proof structure, relates in particular to a kind of fool proof mechanism.
Background technology
Electric connector generally is made up of plug and socket, and plug and socket is after correct pairing plugs together, and electric connector could move, and finishes this structure or the mechanism that electrical connector plug and the correct pairing of socket are plugged together, and is commonly referred to as fool proof mechanism.
The fool proof knot mechanism of tradition connector is generally key and cooperates with keyway, same size, the position of the key of the connector of different model on connecting is different, realize the model difference with this, and realize the fool proof function preventing that namely plug and socket is unpaired to be caused whole electrical system cisco unity malfunction or damage electrical system because misoperation makes at plug, when socket plugs together.The fool proof mechanism that the conventional plastic connector will use this key to cooperate with keyway, general design is at plug body and jack housing several pairing key or keyway to be set respectively, different model key or the keyway position on shell is different, so just can realize the fool proof function.
Electrical system on the new-energy automobile is comparatively complicated now, can use the connector of a plurality of same sizes, so it is also higher that fool proof requires, if use traditional fool proof mechanism to realize the fool proof function, just need realize a mould multidigit or produce the mould of many parafacies same specification different model at the mould of plug or jack housing.There are the following problems in present traditional fool proof mechanism: on the one hand, if the connector volume is little, can use a mould multidigit to handle, but the connector on the new-energy automobile requires through-current capability big now, so the volume of connector is bigger, one mould multidigit cannot realize, can only realize by producing how secondary mould.On the other hand, do not have and take still how secondary mould of a mould multidigit, same defective is arranged, namely homogeneity of product is bad, production cost height.As seen traditional fool proof mechanism can not satisfy the instructions for use of new-energy automobile.
The utility model content
At the weak point that prior art exists, the purpose of this utility model is to provide a kind of novel fool proof mechanism that had not only had the fool proof function but also can ensure product consistency, and can solve the problems of the technologies described above effectively.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fool proof mechanism, comprise socket, plug and socket key letter, described socket is provided with at least one socket coding groove, described plug is provided with the plug key letter erecting bed corresponding with socket coding groove quantity, position, and on this plug key letter erecting bed the plug key letter is installed, the plug key letter erecting bed socket coding groove corresponding with the position that the plug key letter is installed mates and sliding plug mutually, and described socket key letter and described socket coding groove cooperatively interact.
In order to realize the utility model better, have plug key letter inserting groove in the described plug key letter erecting bed, described plug key letter is plugged in the plug key letter inserting groove.
The utility model provides a kind of preferred plug key letter structure technology scheme to be: described plug key letter cross sectional shape is " worker " font, and plug key letter middle part has slot to make way, and an end end of plug key letter has flag-shaped and buckles.
For the plug and socket that guarantees fool proof mechanism comparatively stably links together, described socket is provided with lock, and described plug is provided with the lock body that matches with lock.
The utility model is compared than prior art, has the following advantages and beneficial effect:
(1) plug of the present utility model is provided with plug key letter erecting bed, corresponding plug key letter erecting bed coupling correspondence is provided with socket coding groove on the socket, during use, in plug end, select plug key letter coupling to be connected in quantity and the position of plug key letter erecting bed; In socket end, select corresponding socket key letter to be plugged in quantity and the position of socket coding groove simultaneously, plug can only could correctly be connected with the socket coupling along a kind of mode like this, has realized the foolproof function of electric connector.Simultaneously, the utility model can ensure product consistency, can carry out suitable assembling according to actual conditions, has strengthened the versatility of plug, socket parts.
(2) socket of the present utility model is provided with lock, and plug is provided with the lock body that matches with lock, and after plug and socket connected, lock body and lock can guarantee that the plug and socket of fool proof mechanism comparatively stably links together.
