Description
Technical field
The utility model relates to a kind of for set up the connector being electrically connected between electric contacts.
Background technology
Inverse inserting-preventing connectors is used for connecting reliably electric lead, and should safely electric energy be delivered to the second electric lead from the first electric lead.Inverse inserting-preventing connectors is applied in building automatic, technical device, automobile and industrial equipment especially.In industrial equipment, inverse inserting-preventing connectors is in being commonly used in the switch cubicle or control cubicle with robust metallic housing.For inverse inserting-preventing connectors, two safe switching performances that patch housing are required very high, avoid patching housing and unclamp and make operator directly touch charged wire or be short-circuited.But on the other hand, it is also important that can be fast and unclamp simply the connection that patches housing, to change targetedly and rapidly the damage electric component that is positioned at connector wire input side or is positioned at connectors wire outlet side when the maintenance.Existing inverse inserting-preventing connectors exists following not enough: first, easily anti-inserted between male and female, to use, bring hidden danger; Secondly, between electrode, easily leak electricity, even short circuit, affects normal power supply; Again, when electrode and external power supply wire bonding, often, because welding block is excessive, cause between electrode and leak electricity, even short circuit.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of simple in structure, be difficult for anti-plug, be difficult for electric leakage and the good inverse inserting-preventing connectors of reliability.
The utility model solves the technical scheme that its technical problem adopts: a kind of inverse inserting-preventing connectors, comprise male and female, male with in female, be respectively provided with a pair of electrode that is suitable for pegging graft and is connected, between the pair of electrodes hole of male front end, be provided with the insulating spacer that anti-short circuit is used, can avoid electric leakage or short circuit between electrode, the front inner wall of female is provided with the guide vane end stop that inverse plugging is used, on the sidewall of male, be provided with the groove matching with this guide vane end stop, for preventing because welding block is excessive, cause the generation of the even short circuit of leaking electricity between electrode, and the convenience of bonding wire, electrode in described male and female extends the rear end of male and female and has bonding wire end with the contact-making surface of male and female, described bonding wire end has the semi arch gap arranging dorsad, described bonding wire end is provided with the protective sleeve of Dual-aperture integral body structure, on described protective sleeve, be provided with clamping block, between described bonding wire end and male and the contact-making surface of female, there is the annular gap that card is established protective sleeve running-on, described male with in female, be provided with the card interface corresponding with described clamping block.
Further, in order to play better clamping effect, the quantity of described clamping block and card interface is four, can be effectively fixing protective sleeve.
Further, described male and female one side have the trapezoidal auxiliary section for inverse plugging separately, can more effectively prevent anti-plug, and the convenient both positive and negative polarity of distinguishing.
The beneficial effects of the utility model are; in plug-in connector for electric connection of the present utility model; between the pair of electrodes hole of male front end, be provided with the insulating spacer that anti-short circuit is used; can avoid electric leakage or short circuit between electrode; the front inner wall of female is provided with the guide vane end stop that inverse plugging is used; on the sidewall of male, be provided with the groove matching with this guide vane end stop; can prevent anti-plug; electrode is easily distinguished both positive and negative polarity; be provided with protective sleeve for convenience detach; the generation of even short circuit and very convenient welding can prevent from leaking electricity between electrode.
