Description
Technical field
The utility model relates to a kind of plug-in connector for electric connection, is a kind of sparkproof electrical connectors with spacing delay function specifically.
Background technology
Existing electrical connectors, in being applicable to the electrical equipment of relatively high power or installing time, the electrode in the male and female plug in plug connector directly contacts, immediate current is excessive, contact point very easily plays pyrophoric behavio(u)r, when serious, not only can burn out socket or electrical equipment, also can damage human body.
Summary of the invention
The purpose of this utility model is exactly a kind of sparkproof electrical connectors with spacing delay function of utility model, in the time of its logical super-high-current, is difficult for producing spark, can protect plug-in connector for electric connection or components and parts not damaged, and easy to operate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sparkproof electrical connectors with spacing delay function, comprise public plug and female, it is characterized in that: described public plug with in female, be respectively provided with a pair of positive and negative electrode that is suitable for pegging graft and is connected, this electrode is injection-moulded in a housing, and this housing is an injection molding body; Wherein the positive electrode in female is made up of the front termination electrode not being connected and rear termination electrode, and at a resistance of the outside of front termination electrode and rear termination electrode series connection, its three interconnects.
Further, for resistance is firmly fixed in housing injection molding body, described resistance is arranged in female in the injection molding body between pair of electrodes.
Further, the excessive electrode that causes public plug of exerting oneself directly or fast contacts the rear termination electrode in female when pegging graft, thereby resistance cannot be shunted and make immediate current excessive, produce spark, lose sparkproof function, described female housing is provided with the spacing time-delay mechanism that inserts public plug for controlling female, effect can be detained after the positive electrode in public plug touches the front termination electrode in female exactly, make its immediate current can be not excessive, thereby can not produce spark, thereby reach the effect to large electric current safety conductive.
Further, in order to realize spacing delay function, described spacing time-delay mechanism is provided with an elasticity clinching that exceeds public plug inner chamber on female housing insertion section, elasticity clinching top to female housing top spacing L
1<rear end electrode tip is to female housing top spacing L
2; In the time that the end face of public plug is encountered in the end of elasticity clinching, ensure that the positive electrode end in its public plug has touched the front termination electrode in female, and do not touched the end of rear termination electrode, avoid like this moment to connect and produced pyrophoric phenomenon.
Further, easy to operate in order to realize, when use, more insure.Described elasticity clinching is designed to one end connection female housing, an other end and is the elastic bumps that upwarps arc strip shape, for spacing.When user shifts the end face of public plug the end of elasticity clinching onto like this, must press elasticity clinching, could continue public plug to insert in female, this has just been avoided user's operate miss cause resistance to shunt and produce pyrophoric phenomenon, and this motion action gets up not only to facilitate but also insure.
Further, due in the time using high-power electric appliance or other devices, its size of current is not certain, and therefore the size of its resistance also changes thereupon, and described resistance value is 1 ~ 50 Ω.
The beneficial effects of the utility model are: 1, because female housing is provided with a spacing time-delay mechanism, when insertion, need multiplex Pressing fastener action, make like this resistance shunt if having time, when using, user needn't worry in female moment insertion public plug, occurred the phenomenon of spark, this structure makes in use more insurance of plug; 2, simple in structure, easy to operate.

Embodiment
As shown in Figures 1 to 5, the utility model provides a kind of sparkproof electrical connectors with spacing delay function, comprise public plug 1 and female 2, it is characterized in that: described public plug 1 and female 2 be interior is respectively provided with a pair of positive and negative electrode (11,12,21,22) that is suitable for pegging graft and is connected, this is injection-moulded in a housing (13,23) electrode, and this housing (13,23) is an injection molding body; Wherein the positive electrode 21 in female 2 is made up of the front termination electrode 211 not being connected and rear termination electrode 212, and at a resistance 24 of the outside of front termination electrode 211 and rear termination electrode 212 series connection, its three interconnects.
Further, for resistance is firmly fixed in housing injection molding body, described resistance 24 is arranged in the injection molding body between pair of electrodes in female 2 (21,22).
Further, the excessive electrode that causes public plug of exerting oneself directly or has fast contacted the rear termination electrode in female when pegging graft, thereby resistance cannot be shunted and make immediate current excessive, produce spark, lose sparkproof function, described female housing 23 is provided with the spacing time-delay mechanism 25 that inserts public plug 1 for controlling female 3, acts on after the positive electrode 11 in public plug touches the front termination electrode 211 in female exactly and can be detained, and makes its resistance can play shunting action.
Further, in order to realize spacing delay function, described spacing time-delay mechanism 25 is provided with an elasticity clinching 251 that exceeds public plug inner chamber on female housing insertion section 231, and these elasticity clinching 251 tops are to female housing 23 top spacing L
1<rear termination electrode 212 tops are to female housing 23 top spacing L
2; In the time that the end face of public plug 1 is encountered in the end of elasticity clinching 251, ensure that positive electrode 11 ends in its public plug have touched the front termination electrode 211 in female, and do not touch the end of rear termination electrode 212, avoid like this moment to connect and produced pyrophoric phenomenon.
Further, easy to operate in order to realize, when use, more insure.Described elasticity clinching 251 is designed to one end connection female housing 23, an other end and is the elastic bumps that upwarps arc strip shape, for spacing.When user shifts the end face of public plug 1 end of elasticity clinching 251 onto like this, must press elasticity clinching, could continue public plug 1 to insert in female 2, this has just been avoided user's operate miss cause resistance 24 to shunt and produce pyrophoric phenomenon, and this motion action gets up not only to facilitate but also insure.
