[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The utility model provides a three-phase terminal structure for a vehicle electric scroll compressor controller. The three-phase column of the compressor is inserted between the fixed terminal and the movable block. The knob bolt is turned to drive the fastener to move, so that the fastener's plug-in column is inserted into the box body, squeezing the movable block, so that the movable block and the fixed terminal clamp the three-phase column of the compressor, thereby improving the connection stability. Figure 1-Figure 4 , including: a connection box 100, a terminal assembly 200 and a fastener 300.

[0030] The connection box 100 includes a box body 110, a slot 120, a sliding hole 130 and a rotating hole 140. The box body 110 is provided with a slot 120 that passes through from top to bottom, a sliding hole 130 that passes through the slot 120 is provided on the side, and a rotating hole 140 is provided on the side of the box body 110.

[0031] The slots 120 are three rectangular slots evenly distributed on the box body 110 , the sliding holes 130 are arranged in one-to-one correspondence with the slots 120 , and the rotating hole 140 is located between two sliding holes 130 .

[0032] The terminal assembly 200 is disposed in the slot 120. The terminal assembly 200 includes a fixed terminal 210, a slide slot 220, a movable block 230 and a slider 240. The fixed terminal 210 is fixed at one end of the slot 120. The fixed terminal 210 is provided with the slide slot 220. The movable block 230 is provided with a slider 240 connected to the slide slot 220.

[0033] The movable block 230 moves on the slide groove 220 of the fixed terminal 210 through the slider 240 to change the distance between the movable block 230 and the fixed terminal 210 .

[0034] The fastener 300 is arranged on the sliding hole 130 , and the fastener 300 includes a movable plate 310 , a plug post 320 and a knob bolt 330 . The plug post 320 inserted into the sliding hole 130 is arranged on the side of the movable plate 310 , and the knob bolt 330 connected to the rotating hole 140 is arranged on the movable plate 310 ;

[0035] Among them, a bearing is connected between the knob bolt 330 and the rotating hole 140, and an anti-slip ridge is set at the knob at the outer end of the knob bolt 330. When the knob bolt 330 is rotated, the movable plate 310 is driven to move under the action of thread feed, so that the plug column 320 is inserted into the slot 120 through the sliding hole 130, squeezing the movable block 230 inside.

[0036] Due to the large gap between the fixed terminal 210 and the movable block 230, it is impossible to effectively contact the three-phase column of the compressor. A clip 250 is provided on the adjacent side of the fixed terminal 210 and the movable block 230. The clip 250 is made of an elastic metal sheet and is in the shape of a "J". The clip 250 contacts the three-phase column of the compressor and is effectively connected to the three-phase column of the compressor.

[0037] Since there is no pre-fixation when inserting the compressor three-phase column, it is easy to loosen and fall off. Therefore, a spring 260 is arranged between the side wall of the movable block 230 and the inner wall of the slot 120. The spring 260 is arranged at the upper and lower ends of the side wall of the movable block 230. In the natural state of the spring 260, the fixed terminal 210 fits with the movable block 230.

[0038] When the compressor three-phase column is inserted between the fixed terminal 210 and the movable block 230, the fixed terminal 210 and the movable block 230 are stretched apart. At this time, the spring 260 is compressed and deformed. Under the rebound action of the spring 260, the movable block 230 is clamped on the compressor three-phase column for pre-fixation.

[0039] In order to facilitate fixing of the box body 110 itself, positioning holes 150 are provided at both ends of the box body 110, and bolts are installed and positioned on the box body 110 through the positioning holes 150.

[0040] Since the movable plate 310 needs to be in contact with the staff, in order to avoid electric shock due to leakage, the movable plate 310 and the plug post 320 are both made of insulating parts to avoid electric shock during operation.

[0041] During specific use, the knob bolt 330 is turned, and the movable plate 310 is driven to move under the action of thread feed, so that the plug column 320 moves in and out of the sliding hole 130, and then the three-phase column of the compressor is inserted between the fixed terminal 210 and the movable block 230, and the fixed terminal 210 and the movable block 230 are stretched apart. At this time, the spring 260 is compressed and deformed, and the movable block 230 is clamped on the three-phase column of the compressor under the rebound action of the spring 260 for pre-fixation. The knob bolt 330 is rotated in the opposite direction, and the plug column 320 is inserted into the slot 120 through the sliding hole 130, squeezing the movable block 230 on the inside, so that the movable block 230 is clamped on the outside of the three-phase column of the compressor to ensure the stability of the connection.

[0042] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
