Above-mentioned anchor fitting, preferred, described iron core and Plastic Parts are installed on the described radiator by screw, packing ring and spring washer.。

The disclosed anchor fitting of the utility model embodiment is welded on Hall element on the same sensor pcb, has effectively utilized the space, has greatly dwindled the volume of electric vehicle controller.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the front elevation of electric vehicle controller current sensor anchor fitting in the prior art;

Fig. 2 is the front elevation of the disclosed electric vehicle controller current sensor of the utility model embodiment anchor fitting;

Fig. 3 is the lateral plan of the disclosed electric vehicle controller current sensor of the utility model embodiment anchor fitting.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The front elevation of the disclosed electric vehicle controller current sense of the utility model embodiment anchor fitting as shown in Figure 2, this anchor fitting mainly comprises radiator 101, iron core 106, Plastic Parts 111, copper busbar 102, Hall element 107, sensor pcb 108, conductive pin 109 and controller printed circuit board (PCB) 110.

Plastic Parts 111 is arranged on the radiator 101, copper busbar 102 is arranged on the Plastic Parts 111, binding post U, V, the W of copper busbar 102 overlap upper core 106 respectively, Hall element 107 in iron core 106 air gaps is welded on the sensor pcb 108, and sensor pcb 108 is connected on the controller printed circuit board (PCB) 110 by conductive pin 109.But but conductive pin plays not only fixation of sensor printed circuit board (PCB) but also UNICOM's circuit.

The lateral plan of the disclosed electric vehicle controller current sensor of the utility model embodiment anchor fitting as shown in Figure 3, three-phase Hall element 107 all is welded on the sensor pcb 108, and sensor pcb 108 is connected on the controller printed circuit board (PCB) 110 by conductive pin 109.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
