Abstract
The utility model discloses a heavy current connector. The heavy current connector relates to the heavy current connector field and comprises a plug and an accepting member, and the tail parts of the plug and the accepting member are connected with leads. The plug and the accepting member are cylindrical conductors, the middle part of the accepting member is equipped with a cavity in which a resistor strip is filled, and the head of the resistor strip is exposed out of the cavity. The head of the resistor strip is equipped with an injection molding insulator radially, and the plug can be in sealing matching with the accepting member. The plug and the accepting member are cylindrical conductive structures, at the same time, and the resistor strip is placed in the cavity of the accepting member, thereby achieving the purposes of preventing from generating spark at the contact instant and preventing explosion.
Description
Technical field
The present invention relates to current delivery field, be specifically related to a kind of large electric current connector.
Background technology
Large electric current connector is mainly used in large-current electric device, by the connection of fixture wire being realized to the conducting of electric current, China Patent Publication No. CN103038949A discloses large electric current and has inserted interconnection system connector, by chamber is set in housing, connector is packed in this chamber, on this connector, be also provided with contact member simultaneously, by inserted mode, realize the conducting of electric current, so its weak point is, when lead-in wire touches contact member or connector, because electric current is larger, can moment produce spark, even there is explosion phenomenon, therefore how to provide a kind of and can prevent that Contact from producing spark explosion-proof aobvious particularly necessity of jockey.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of large electric current connector, by plug and supporting are made as to cylinder conductive structure, place resistor stripe in the cavity of supporting simultaneously, to reach, prevent that Contact from producing the object of spark and prevent exploding.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of large electric current connector, comprise plug and supporting, afterbody at described plug and described supporting is connected with lead-in wire, the electric conductor that described plug and described supporting are column structure, at the middle part of described supporting, for there being cavity, at described cavity inside, be filled with resistor stripe, the head of described resistor stripe is exposed to the outside of described cavity, on the head of described resistor stripe, be radially provided with injection moulding insulator, described plug can be sealed and matched mutually with described supporting.
Further, the external diameter of described plug is identical with the internal diameter of described supporting, at described plug, is provided with opening with the described supporting place of matching.
Pass through technique scheme, the present invention is sealed and matched by described plug and described supporting, can On current, inside at described supporting arranges resistor stripe, and injection moulding insulator is set on described resistor stripe, can make described plug with described supporting when contacting, by described resistor stripe, reduce electric current and make it can not produce spark, thereby realize the object to large electric current safety conductive.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 2 is the plug construction schematic diagram of the disclosed a kind of large electric current connector of the embodiment of the present invention;
Fig. 3 is the supporting structural representation of the disclosed a kind of large electric current connector of the embodiment of the present invention.
Numeral and the represented corresponding component title of letter in figure:
1. plug; 2. injection moulding insulator; 3. resistor stripe; 4. cavity; 5. supporting; 6. opening.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
As shown in Figure 1, a kind of large electric current connector, comprise plug 1 and supporting 5, afterbody at described plug 1 and described supporting 5 is connected with lead-in wire, the electric conductor that described plug 1 and described supporting are column structure, at the middle part of described supporting 5 for there being cavity 4, at described cavity inside, be filled with resistor stripe 3, the head of described resistor stripe 3 is exposed to the outside of described cavity 4, on the head of described resistor stripe 3, be radially provided with injection moulding insulator 2, described plug 1 can be sealed and matched mutually with described supporting 5.
In use, described resistor stripe 3 is packed in the described cavity 4 of described supporting 5, described plug 1 is inserted to described supporting 5, realize the conducting of electric current, when electric current flows to described supporting 5 from described plug 1, because the head of described resistor stripe 3 is exposed to the outside of described cavity 4, therefore electric current can first touch described resistor stripe 3, the injection moulding insulator 2 being arranged on described resistor stripe 3 can be blocked electric current from the outer surface circulation of described resistor stripe 3, therefore electric current can be from described resistor stripe 3 internal circulations, owing to being loaded on described in resistor stripe 3 in described supporting 5, therefore electric current can flow into described supporting 5, and flow out from the lead-in wire of described supporting 5 afterbodys, this structure can avoid electric current when described plug 1 contacts with described supporting 5, to produce the also blast of moment spark, played the object of safe conducting.
Further, in conjunction with Fig. 2 and Fig. 3, the external diameter of described plug 1 is arranged identical with the internal diameter of described supporting 5, at described plug 1, with described supporting 5 places of matching, opening 6 is set, when described plug 1 is connected with described supporting 5, the opening 6 arranging on described plug 1 can make described plug 1 have elasticity, can make on the one hand described plug 1 more laborsaving when being socketed with described supporting, can make on the other hand described plug 1 tightly encase described supporting, reach closely sealed connection object.
Above-described is only the preferred implementation of a kind of large electric current connector of the present invention; it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
