The four fastening sleeves 244 are respectively accommodated in the four mounting holes 242 of the connector rubber core 20, and the gasket 27 is sleeved on the connecting part 22, so that the connecting part 22 is inserted into the avoiding hole 272, and the four through holes 274 respectively face the four mounting holes 242.

The signal leads 80, the power leads 90 and the locking members 95 are layered in the installation positions and do not interfere with each other, so as to improve the efficiency of assembling the locking members 95 and reduce the risk of core wire damage. The height of the isolation part 653 is greater than the height of the locking member 95, so that the electrical gap between the two locking members 95 is increased; and the isolation part 653 is also beneficial for personnel to grasp, so that the installation is more convenient.The positioning strip 656 is in interference fit with the first clamping groove 6261, which can enhance the stability of the first and second wire limiting members 62 and 65 after installation and the overall anti-collision strength of the connector 100.

[0058] The signal wire 80 of the connector 100 of the present application can be wired from the wire hole 652 of the second wire limiting member 65 and the opposite port of the wire slot 624. There is no signal wire 80 between the first connecting sections 44 of the two power terminals 40, so the cross-sectional area of the first connecting section 44 can be increased, the conductive part 94 of the power wire 90 is also increased in size, the contact area of the power terminal 40 and the power wire 90 is increased, which can meet the requirement of large current transmission. Secondly, the signal wire 80 can be wired from the two avoiding ports 6513 and the wire hole 652 of the second wire limiting member 65 to meet the different space wiring requirements of the signal wire 80. The second wire limiting member 65 has a larger grip and a wire hole, which reduces the process difficulty. Various fixing methods of the first and second wire limiting members 62 and 65 are achieved in limited space, which makes the connection of the first and second wire limiting members 62 and 65 firm. The rotation stopping column 627 of the first wire limiting member 62 is clamped in the limiting port 657 of the second wire limiting member 65, and the power wire 90 is positioned in the rotation stopping slot 6272 to prevent the power wire 90 from rotating and to quickly position and install the power wire 90 to the power terminal 40, which greatly improves the assembly efficiency. The power terminal 40, the signal terminal 50 and the large signal terminal 57 all adopt a double-sealing ring structure, which greatly reduces the problem of poor air tightness caused by the sealing ring being cut or extruded deformation, and greatly improves the stability of the air tightness of the product.

[0059] As Figures 17-21As 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 wire outlet limiting member 62a and the second wire outlet limiting member 65a in the second embodiment are connected by the cooperation of the fixing strip and the fixing slot instead of the cooperation of the second clamping groove and the second clamping block between the connecting plate of the first wire outlet limiting member 62 and the second wire outlet limiting member 65 in the first embodiment. Specifically, the limiting cover 621 and the positioning cover 651 are connected by the cooperation of the fixing strip 628 and the fixing slot 6512, the length direction of the fixing strip 628 is parallel to the axial direction of the power terminal 40, the fixing strip 628 is arranged in one of the limiting cover 621 and the positioning cover 651, and the fixing slot 6512 is arranged in the other one of the limiting cover 621 and the positioning cover 651. In this embodiment, the fixing strip 628 is arranged in the limiting cover 621, the fixing slot 6512 is arranged in the positioning cover 651, and the fixing strip 628 is inserted into the fixing slot 6512 to position the second wire outlet limiting member 65a relative to the first wire outlet limiting member 62a. Specifically, the surface of the limiting cover 621 away from the outer peripheral plate 626 is provided with the fixing strip 628 on the opposite sides of one end of the wire outlet slot 624, the surface of the positioning cover 651 provided with the isolation portion 653 is provided with the fixing slot 6512 on the opposite sides of the wire outlet hole 652, and the two fixing strips 628 are respectively inserted into the two fixing slots 6512 to fixedly connect the second wire outlet limiting member 65a to the first wire outlet limiting member 62a.

[0060] Optionally, the fixing strip 628 and the inner peripheral surface of the fixing slot 6512 are connected by the cooperation of the clamping hole 6282 and the clamping block 6514. In this embodiment, the inner peripheral surface of the fixing slot 6512 is provided with the clamping block 6514, and the outer peripheral surface of the fixing strip 628 is provided with the clamping hole 6282. When the fixing strip 628 is inserted into the fixing slot 6512, the clamping block 6514 is clamped in the clamping hole 6282. Since the first wire outlet limiting member 62a and the second wire outlet limiting member 65a in the second embodiment omit the second clamping groove and the second clamping block, the connection structure of the second wire outlet limiting member 65a is simplified, the complexity of the mold is reduced, and the development and manufacturing costs are reduced.

[0061] In other embodiments, the fixing strip 628 is arranged on the surface of the positioning cover 651 away from the isolation portion 653, and the fixing slot 6512 is arranged on the surface of the limiting cover 621 away from the outer peripheral plate 626. When the second wire outlet limiting member 65a is sleeved on the first wire outlet limiting member 62a, the fixing strip 628 is inserted into the fixing slot 6512.

[0062] The second cable exit limiting member 65a in the second embodiment omits the wire tube 658 based on the first cable exit limiting member 62a in the first embodiment. In the second embodiment, the positioning cover 651 of the second cable exit limiting member 65a has an isolation plate 6532 at one end of the isolation portion 653. The length direction of the isolation plate 6532 is perpendicular to the length direction of the isolation portion 653, and the isolation plate 6532 is located between the two clearance holes 650 and the two fixing grooves 6512. The isolation plate 6532 and the isolation portion 653 form a T-shaped partition structure, resulting in a larger ground area for the T-shaped partition structure, thereby increasing its strength and facilitating the pre-positioning of the conductive portion 94 of the power cable 90. It also reduces damage caused by large torque during the installation of the fastener 95.

[0063] The assembly method and interference effect of connector 100a in the second embodiment are the same as those in the first embodiment, and will not be repeated here.

[0064] like Figures 22-25 As shown, the structure of connector 100b in the third embodiment of this application is similar to that of connector in the second embodiment, except that: in the third embodiment, the limiting cover 621 of the first cable exit limiting member 62b of connector 100b has a fixing strip 628 at at least one end of the cable exit groove 624, the fixing strip 628 is close to the outer edge of the limiting cover 621, and the positioning cover 651 of the second cable exit limiting member 65b has a fixing groove 6512 near its outer edge, the fixing strip 628 can be fixed in the fixing groove 6512. The fixing strip 628 and the inner circumferential surface of the fixing groove 6512 are connected by a locking hole 6282 and a locking block 6514. In this embodiment, the inner circumferential surface of the fixing groove 6512 has a locking block 6514, and the outer circumferential surface of the fixing strip 628 has a locking hole 6282. When the fixing strip 628 is inserted into the fixing groove 6512, the locking block 6514 is engaged in the locking hole 6282. Since the positioning cover 651 only has one fixing groove 6512, there is a large space on the positioning cover 651 to increase the opening area of ​​the cable outlet 652, making it easier to thread the signal cable.

[0065] Optionally, the outer periphery of the positioning cover 651 of the second wire outlet limiting piece 65b is provided with four positioning strips 656, which are uniformly arranged in a circle around the periphery of the positioning cover 651; the outer peripheral plate 626 of the first wire outlet limiting piece 62b is provided with four first clamping grooves 6261, which are uniformly arranged in a circle around the periphery of the limiting cover 621; two of the first clamping grooves 6261 are respectively opposite to and communicate with the opposite ends of the wire outlet groove 624; the four positioning strips 656 are respectively inserted into the four first clamping grooves 6261, and the positioning strip 656 and the corresponding first clamping groove 6261 are in interference fit, so as to enhance the cooperation stability of the first wire outlet limiting piece 62b and the second wire outlet limiting piece 65b; in the process of locking the locking piece 95 on the power supply terminal 40, the strength is higher, and the anti-rotation and anti-fracture effects are good. Therefore, while meeting the requirements of increasing the rated current and the wire of the signal wire outlet, the parts also meet the up-down mold stripping, the mold structure is simplified, and the mold cost and the production cost are reduced.

[0066] In other embodiments, the inner periphery of the fixing groove 6512 is provided with a clamping hole, and the outer periphery of the fixing strip 628 is provided with a clamping block, when the fixing strip 628 is inserted into the fixing groove 6512, the clamping block is clamped in the clamping hole.
