There is no signal output line 80 between the first connecting sections 44 of the two power terminals 40. Therefore, the cross-sectional area of ​​the first connecting section 44 can be increased, and the conductive portion 94 of the power output line 90 is also increased in size accordingly, thereby increasing the contact area between the power terminal 40 and the power output line 90, which can meet the requirements of large current transmission. Secondly, the signal line 80 can be connected through the two avoidance openings 6513 and the line hole 652 of the second line limiter 65 to meet the different spatial line connection requirements of the signal line 80.

[0060] like Figure 17-Figure 21As shown, the structure of the connector 100a in the second embodiment of the present application is similar to that of the connector in the first embodiment, except that: the first outlet limiter 62a and the second outlet limiter 65a in the second embodiment are connected by a fixed bar and a fixed groove to replace the second card slot and the second card block of the connecting plate between the first outlet limiter 62 and the second outlet limiter 65 in the first embodiment. Specifically, the limit cover 621 and the positioning cover 651 are connected by a fixed bar 628 and a fixed groove 6512, the length direction of the fixed bar 628 is parallel to the axial direction of the power terminal 40, the fixed bar 628 is provided on one of the limit cover 621 and the positioning cover 651, and the fixed groove 6512 is provided on the other of the limit cover 621 and the positioning cover 651.

In this embodiment, the inner circumference of the fixing groove 6512 is provided with the clamping block 6514, and the outer circumference of the fixing strip 628 is provided with the clamping hole 6282. When the fixing strip 628 is inserted into the fixing groove 6512, the clamping block 6514 is clamped in the clamping hole 6282. Since the second clamping groove and the second clamping block are omitted in the first outlet limiter 62a and the second outlet limiter 65a in the second embodiment, the connection structure of the second outlet limiter 65a is simplified, the complexity of the mold is reduced, and the development and manufacturing costs are reduced.

The isolation plate 6532 is located between the two avoidance holes 650 and the two fixing grooves 6512. The isolation plate 6532 and the isolation part 653 form a T-shaped partition structure, so that the T-shaped partition structure has a larger coverage area, thereby increasing the strength, being more conducive to the pre-positioning of the conductive part 94 of the power outlet line 90, and reducing the damage of the locking member 95 when a large torque is generated during installation.

[0064] The assembly method and the relief effect of the connector 100a in the second embodiment are the same as those in the first embodiment, and will not be described in detail herein.

[0066] Optionally, four positioning strips 656 are provided on the outer periphery of the positioning cover 651 of the second outlet line limiter 65b, and the four positioning strips 656 are evenly spaced and arranged in a circle around the circumference of the positioning cover 651; four first card grooves 6261 are provided on the outer peripheral plate 626 of the first outlet line limiter 62b, and the four first card grooves 6261 are evenly spaced and arranged in a circle around the circumference of the limiting cover 621, wherein two first card grooves 6261 are respectively opposite to and connected to the opposite ends of the outlet line groove 624, and the four positioning strips 656 are respectively inserted into the four first card grooves 6261, and the positioning strips 656 are interference fit with the corresponding first card grooves 6261 to enhance the matching stability between the first outlet line limiter 62b and the second outlet line limiter 65b; in the process of locking the locking piece 95 to the power terminal 40, the strength is high, which can play a better anti-rotation and anti-fracture role.
