Description
Technical field
The utility model relates to the anti-reverse positive and negative joint of a kind of electric machine controller high-voltage power-line, specifically is the splicing ear that HVDC is imported power line and controller body on the electric machine controller.
Background technology
Electric machine controller is the critical component on the electric automobile, and the electric energy that it will be provided by battery through conversion and the control of controller electronics with electrical device, makes rule as expected moving of motor.Because the power of drive motors is bigger, the power supply voltage level on the electric automobile is than higher.Therefore, electric machine controller belongs to high voltage electric equipment, and controller is the power line that must be connected to the electric energy input, also just has the tab terminal of installing with the fixed power source line.There are positive and negative the two poles of the earth in power line, and the tab terminal of current controller power source line both positive and negative polarity uses bolt to connect more, and this connected mode connects under the Vehicular vibration environment reliably, is difficult for getting loose.But because the geometry of the two poles of the earth binding post, connected mode, thread size etc. are all the same; If not explanation; Positive and negative electrode is distinguished in inconvenience when actual field is installed; Thereby the situation that very easily causes the reversal connection of positive and negative electrode power line to cause controller to damage, the more serious damage that also possibly cause other high-voltage electrical equipments causes security incident even.
Summary of the invention
The purpose of the utility model is to provide a kind of electric machine controller high-voltage power-line anti-reverse positive and negative joint in order to address the above problem, and prevents that the positive and negative power supply line from connecing instead.
The technical scheme of the utility model: the anti-reverse positive and negative joint of the electric machine controller high-voltage power-line of the utility model comprises positive power line terminal and positive control device junction block and negative power line terminal and negative control device junction block; Its positive power line terminal and positive control device junction block adopt square or circular profile, and negative power line terminal and negative control device junction block adopt circle or the square profiles with anodal difference.
Described square controller junction block with the joint face of square power line terminal in the middle of be the groove with square power line terminal coupling; The groove middle part is the first electrode connecting hole, and the first electrode connecting hole at groove middle part is identical with the first terminal connecting hole on the square power line terminal; The first group of installing hole that is connected with controller arranged on the shoulder of groove both sides.
Described circular controller junction block comprises the round platform that is connected with circular power line terminal, is the second electrode connecting hole in the middle of the round platform; The second electrode connecting hole in the middle of the round platform is identical with the second terminal connecting hole on the circular power line terminal.The limit, outer is arranged at the outer bottom of round platform, and the second group of installing hole that is connected with controller arranged on the limit, outer.
The diameter R of described circular power line terminal is greater than the width L of groove.
Described anode electrode connecting hole is different with the diameter of negative electrode connecting hole.
The advantage of the utility model: the utility model keep original inscribe before bolted under; Connect the terminal of shape and the bolt of junction block and use different-diameter through difference; Make when having kept adopting bolt to connect high reliability the reversal connection at the two poles of the earth in the time of actual installation being prevented again.

Embodiment
The utility model adopts difform splicing ear for the two poles of the earth.Comprise positive power line terminal and positive control device junction block and negative power line terminal and negative control device junction block; Its positive power line terminal and positive control device junction block adopt square or circular profile, and negative power line terminal and negative control device junction block adopt circle or the square profiles with anodal difference.
Like Fig. 1, Fig. 2, Fig. 3: described square controller junction block 2 with the joint face of square power line terminal 1 in the middle of be the groove 2b with square power line terminal 1 coupling; Groove 2b middle part is the first electrode connecting hole 2a, and the first electrode connecting hole 2a at groove 2b middle part is identical with the first terminal connecting hole 1a on the square power line terminal 1; The first group of installing hole 2d that is connected with controller arranged on the shoulder 2c of groove 2b both sides.
Like Fig. 4, Fig. 5, Fig. 6, Fig. 7: described circular controller junction block 4 comprises the round platform 4b that is connected with circular power line terminal 3, is the second electrode connecting hole 4a in the middle of the round platform 4b; The second electrode connecting hole 4a in the middle of the round platform 4b is identical with the second terminal connecting hole 3a on the circular power line terminal 3.Limit, outer 4c is arranged at the outer bottom of round platform 4b, and the second group of installing hole 4d that is connected with controller arranged on the 4c of limit, outer.
The diameter R of described circular power line terminal 3 is greater than the width L of groove 2b.The groove 2b of the square controller junction block 2 that shown circular power line terminal 3 can't be put into.
Described anode electrode connecting hole is different with the diameter of negative electrode connecting hole.
Through said method, make the field connection personnel can discern the binding post of opposed polarity easily.For guaranteeing connection reliability, still adopt bolt to connect, but for further preventing reversal connection, both screwed hole diameters are different, the reversal connection at the two poles of the earth when further preventing actual installation.
