Abstract
The utility model discloses a plug and socket structure capable of bearing large current for an electric vehicle or other specific purposes. A plug structure comprises an insulating head and a male terminal insulating casing which is connected to the insulating head. One or more groups of plug male terminals are in parallel connection in the male terminal insulating casing. The plug male terminals are gold-plated copper terminals. Since one or more groups of wire connection terminals are in parallel connection in the plug and socket and the wire connection terminals in the plug and socket are gold-plated copper terminals, the total passing resistance of the plug and socket is reduced, the generated heat energy is small when the same large current passes, and the load bearing ability of the plug and socket is greatly raised. The practice proves that the maximum current load bearing ability of the plug and socket structure is 120A to 180A which is much higher than the load standard of the 10A to 15A of a traditional triangle-shaped plug or the 25A to 35A of a traditional patch board.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of plug construction that can bear large electric current, comprise insulation head and be arranged on insulation head upper and with the plug male terminal being connected with electrical cables, also comprise male terminal insulation crust, described male terminal insulation crust is connected on insulation head, and in male terminal insulation crust, be arranged in parallel 1 group or organize plug male terminal, described plug male terminal adopts the gold-plated terminal of fine copper more.
Further, described male terminal insulation crust adopts and can bear the heat-resistant fireproof material of 200 ℃ and make.
A kind of socket that can bear large electric current, comprise socket insulation crust and female terminal insulation crust, described female terminal insulation crust is arranged in socket insulation crust, and in female terminal insulation crust, be arranged in parallel 1 group or the socket female terminal coordinating with plug male terminal of organizing more, described socket female terminal adopts the gold-plated terminal of fine copper, described male terminal insulation crust and female terminal insulation crust can be pegged graft, and during in inserting state, plug male terminal is connected with socket female terminal at male terminal insulation crust and female terminal insulation crust.
Further, described female terminal insulation crust adopts and can bear the heat-resistant fireproof material of 200 ℃ and make.
Further, on described socket insulation crust, have the interface coordinating with male terminal insulation crust, it is trapezoidal that interface is.
The beneficial effects of the utility model are:
(1) in plug and socket, be arranged in parallel 1 group or organize binding post more, and the binding post in plug and socket adopts the gold-plated terminal of fine copper, make always reducing by resistance of plug and socket, identical large electric current by time the heat that produces diminish, the load-carrying ability of plug and socket is increased substantially; Be proven, the current load ability of the maximum 120-180A of the utility model is far above the load standard of tradition " product " word plug 10-15A or traditional wired row 25-35A;
(2) binding post in plug and socket is arranged in insulation crust, has reduced the short circuit hidden danger or the Danger Electric shock risk that because binding post is exposed, cause, has improved reliability and the fail safe of plug and socket;
(3) because binding post adopts the gold-plated terminal of fine copper, not only can not cause because of heating surface oxidation, extended the useful life of plug and socket, and the gold-plated terminal of fine copper has good elasticity, when plug male terminal is connected with socket female terminal, be not easy to occur loosening;
(4) compare conventional bolt and connect, plug and socket of the present utility model adopts plug-in design, more convenient to operate, quick, can realize large current applications Fast Installation or high power electric vehicle quick-replaceable battery functi on;
(5) due to plug male terminal and the size of socket female terminal own little, so socket can accomplish identically with common " product " word jack sizes, is directly used in common electric car, strong adaptability.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 4, a kind of large current plug and socket structure for electric motor car or other special-purposes, comprise cable plug 2 and power supply base 3, cable plug 2 comprises insulation 21 and is connected to the male terminal insulation crust 23 in insulation 21, in male terminal insulation crust 23, be arranged in parallel 1 group or organize plug male terminal 22, plug male terminal 22 adopts the gold-plated terminal of fine copper more; Power supply base 3 comprises socket insulation crust 31 and is arranged on the female terminal insulation crust 33 in socket insulation crust 31, in female terminal insulation crust 33, be arranged in parallel 1 group or organize socket female terminal 32, socket female terminal 32 adopts the gold-plated terminal of heavy in section fine copper more; Both can peg graft male terminal insulation crust 23 and female terminal insulation crust 33, and at male terminal insulation crust 23, with female terminal insulation crust 33 during in inserting state, plug male terminal 22 is connected with socket female terminal 32.Owing to being arranged in parallel 1 group or organize binding post in cable plug 2 and power supply base 3 more, and the binding post in cable plug 2 and power supply base 3 adopts the gold-plated terminal of fine copper, so just make always reducing by resistance of plug and socket, identical large electric current by time the heat that produces diminish, the load-carrying ability of plug and socket is increased substantially; Meanwhile, because binding post is arranged in insulation crust, reduce the short circuit hidden danger or the Danger Electric shock risk that because binding post is exposed, cause, improved reliability and the fail safe of plug and socket; In addition, because binding post adopts the gold-plated terminal of fine copper, not only can because of heating, not cause surface oxidation, extended the useful life of plug and socket, and the gold-plated terminal of fine copper has good elasticity, when plug male terminal is connected with socket female terminal, be not easy to occur loosening.
As the further improvement to technique scheme, male terminal insulation crust 23 and female terminal insulation crust 33 adopts and can bear the heat-resistant fireproof material of 200 ℃ and make, as all aromatic polyimide resin etc.When the large function of current can produce amount of heat during in binding post, and male terminal insulation crust 23 and female terminal insulation crust 33 adopt heat-resistant fireproof material just can improve the load-carrying ability of plug and socket, guarantee the fail safe of plug and socket when hot operation.
As the further improvement to technique scheme, on socket insulation crust 31, there is the interface 31a coordinating with male terminal insulation crust 23, interface 31a is trapezoidal.When cable plug 2 and power supply base 3 are pegged graft, male terminal insulation crust 23 inserts by interface 31a, and interface 31a is trapezoidal, therefore only at male terminal insulation crust 23 with interface 31a at once, cable plug 2 can be plugged on power supply base 3, so just avoid plug and socket to occur anti-inserted situation.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
