Abstract
The utility model provides an error connection proof dc power supply plug and socket, comprising a plug body and a socket body; and the conductive contact pins arranged on the plug body have different section sizes, and the jacks matched with the contact pin, on the socket body have two corresponding bore diameters. The technical characteristics of the plug and socket also lie in that the connection end of the plug body is provided with a connection sheath which coincides with the connection end of the socket body; and the conductive contact pins are designed into two different sizes. The utility model has the positive pole and negative pole contact pins designed into two different cross sections and sizes, at the same time, and the jacks designed two different bore diameters which are corresponding to the contact pins, which can avoid effectively mistaking for connecting poles, with simple and safe use. In addition, sheath is provided for coinciding with the plug and the socket, which can effectively improve the stress state of the contact pins and the service life of the plug and socket.
Description
Technical field
The utility model relates to basic electrical component, is a kind of anti-misconnection DC power supply connection-peg specifically.
Background technology
In the electrical interconnection of many access DC power supply, need to use the electric power connecting head, and this type of existing connection-peg, by with the crosspointer in cross section or spininess plug with corresponding be provided with to peg graft with the socket of aperture jack cooperate and form, the corresponding relation of its grafting indicates with the positive and negative electrode sign, during actual the use, the grafting direction is distinguished inconvenient, causes the polarity misconnection easily.In addition,, when connection-peg is subjected to lateral forces, cause contact pin distortion and damage easily, influence the normal use of connection-peg because the connection of this type of connection-peg is only finished by contact pin and cooperating of jack.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of easy to use, can effectively avoid the anti-misconnection DC power supply connection-peg of polarity misconnection.
The purpose of this utility model also is to improve the ability that connection-peg bears the side direction active force, improves the force-bearing situation of contact pin, improves the useful life of connection-peg.
The technical scheme that realizes above-mentioned purpose is: a kind of anti-misconnection DC power supply connection-peg that includes plug body and socket, its conductive pin that places on the plug body is the contact pin of two kinds of different cross section sizes, be arranged on the socket jack for the jack in its two kinds of different apertures of matching; Described contact pin is a circular cross-section, perhaps is the rectangle cross section; Be provided with the plug jacket that the inserted terminal with socket matches at the inserted terminal of plug body; Described conductive pin is arranged to two kinds of different length dimensions, and the front end of the contact pin that its length dimension is big protrudes the front end face of plug jacket, and the front end of the contact pin that length dimension is little places in the front end face of plug jacket.
The utility model is arranged to two kinds of different cross section sizes and two kinds of different length sizes with the positive and negative electrode contact pin, simultaneously jack is arranged to and its corresponding different apertures, can effectively avoid the polarity misconnection, and is easy to use, safe.In addition, by plug, the identical sheath of socket butt joint are set, can effectively improve the force-bearing situation of contact pin, the useful life of improving connection-peg.
Description of drawings
Fig. 1 is the anti-misconnection DC power supply connection-peg structural representation of two pointer type;
Fig. 2 is the anti-misconnection DC power supply connection-peg structural representation of multiple-pin type.
Embodiment
Provide as accompanying drawing 1, the socket 2 that this anti-misconnection DC power supply connection-peg includes plug body 1 and docks with it, its conductive pin 3 that places on the plug body 1 is the contact pin of two kinds of different cross section sizes, is corresponding two kinds of different apertures with its jack 4 that is arranged on the socket 2 that matches; Inserted terminal in plug body 1 is provided with the plug jacket 5 that matches with the inserted terminal of socket 2.
Contact pin 3 of the present utility model can be selected cross sectional shape according to designing requirement, the contact pin in the contact pin in circular cross section and rectangle cross section when specifically implementing.
Contact pin 3 of the present utility model can be arranged to two kinds of different length sizes, during concrete enforcement, relatively large as the contact pin length dimension of negative pole, its front end protrudes the front end face of plug jacket, length dimension as the contact pin of positive pole is less relatively, and front end places in the front end face of plug jacket.
What accompanying drawing 2 provided is that this connection-peg is the multiple-pin type structure, its thicker relatively contact pin be public connecing " " utmost point.
