Abstract
A power conversion device for converting power supply of power supply to power supply of computer host board is composed of the first and the second electric connectors consisting of insulating casing with terminal holes and butt-joint surface, several terminal jacks on circuit board, and insulating cover for holding circuit board and the first and the second electric connectors.
Description
The utility model relates to a kind of power inverter, particularly relates to a kind of convertible two kinds of different electrical power, and the power supply that power supply unit is supplied meets the power inverter of computer motherboard specification.
In information industry, the power supply design of using about computer is mostly with the use of arranging in pairs or groups mutually of the power supply unit of same size and motherboard, be electrically connected between the power supply unit that constitutes by power connector and the motherboard again, as: United States Patent (USP) the 4th, 975,075,4,979,912,5,131,867,5,257,948 and 5,342, No. 221.Yet, along with the continuous increase of computer technology function or the demand of client's use increase gradually, computer motherboard must upgrade thereupon or change, or in order to meet the specification of motherboard of new generation, need the power supply unit of installing new spec on host computer earlier, treat that only must change old motherboard after motherboard of new generation goes on the market gets final product, therefore, can accomplish the voltage that power supply unit is supplied, the demand that electric current can meet new and old motherboard specification earlier, be practical really.Yet known in the past power connector can't be changed the power supply of two kinds of different voltages, electric current.
The purpose of this utility model is to provide a kind of power inverter, can be the needed power supply of motherboard specification with the power source conversion of power supply unit.
The purpose of this utility model is to realize like this, a kind of power inverter promptly is provided, be connected with at least two kinds of electric connectors, which comprises at least: first arrangements of electric connection, it comprises first insulation shell and several the first terminals, be provided with first interface and several the first terminal holes at described first insulation shell, described the first terminal hole is taken in described the first terminal and form first opening on described first interface; At least one second arrangements of electric connection, it comprises second insulation shell and several second terminals, be provided with second interface and several second terminal holes at described second insulation shell, described second terminal hole is taken in described second terminal and form second opening on described second interface; Circuit board which is provided with first and second terminal jacks that can peg graft for described first and second terminal, and with circuit board on relative circuit trace connect; The insulation lid coats the part of described circuit board and described first, second insulation shell; Several electric wires, the one end connects described circuit board, and the other end extends to the outside of described insulation lid and connects an electric connector.
The advantage of the utility model device is, its convertible two kinds of different voltages, electric current use specification to meet host computer, and easy to use and reliable, practical.
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, wherein:
Fig. 1 is the stereogram of the utility model power inverter;
Fig. 2 is the exploded perspective view of another angle of the utility model power inverter;
Fig. 3 removes stereogram behind the 3rd insulation crust for the utility model power inverter;
Fig. 4 removes the stereogram of the 3rd another angle of insulation crust for the utility model power inverter.
See also Fig. 1 and Fig. 2, it is the utility model power inverter 10, it mainly comprises first arrangements of electric connection 12, second arrangements of electric connection 14, circuit board 16, insulation lid 18, several electric wires 13 and an electric connector 15, wherein, first, second arrangements of electric connection 12,14 comprise first respectively, second insulation shell 122,142 and several terminals 124,144 (only showing a terminal among the figure), first, second insulation shell 122, be respectively equipped with interface 1222 on 142,1422 and several terminals hole 1224,1424, this interface 1222,1422 lay respectively at and the direction of docking electric connector (not shown) butt joint, this terminal hole 1224,1424 respectively in order to take in relative terminal 124,144, and at interface 1222, form opening 1226 on 1422,1426, insert and terminal 124 to allow butt joint connector terminals (not shown), 144 combinations.In addition, be that first insulation shell 122 is provided with buckle projection 1221, on second insulation shell 142, be provided with buckle pawl 1421, can be respectively and the relative bayonet unit buckle combination of butt joint electric connector.
Please be simultaneously with reference to Fig. 3 and Fig. 4, this circuit board 16 is provided with several terminals jack 162,164, can insert welding for terminal 124,144 respectively fixes, after terminal 124,144 inserts and is welded in terminal jacks 162,164, promptly relative with circuit board 16 back sides circuit trace (not shown) constitutes electrical connection, and first, second arrangements of electric connection 12,14 is fixed on this circuit board 16.In addition, between terminal jacks 162,164, circuit board 16 is provided with set of circuits jack 166, can insert for aforesaid electric wire 13 1 ends, and circuit trace that can be relative with it connects, the other end at electric wire 13 is connected with electric connector 15, and this electric connector 15 can be connected as motherboard, module card etc. with other electronic component device (not shown), but mat electronic signal control circuit switch.This insulation lid 18 comprises upper cover body 181 and lower cover 182, between it, can form a space, in order to take in the part of foregoing circuit plate 16 and first, second arrangements of electric connection 12,14, first, second arrangements of electric connection 12,14 is exposed with the butted part that docks electric connector, and electric wire 13 is provided with to insulation lid 18 outside extensions from the lateral margin of first arrangements of electric connection 12.
Because first arrangements of electric connection 12 can dock with two kinds of different electrical power connectors respectively with second arrangements of electric connection 14, circuit board 16 can be to meet the power supply that motherboard uses specification with the power source conversion that connects power supply unit one end, therefore, power inverter of the present utility model can provide the effect of two kinds of different voltages of conversion, electric current.
