DETAILED DESCRIPTION

[0035] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the described embodiments.

[0036] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments:

[0037] See also Figure 1 and Figure 2 As shown, the utility model provides an integrated rotary transformer wiring harness, including a wiring harness assembly 1 and a shell 2, and a accommodating hole for accommodating the wiring harness assembly 1 is provided in the shell 2; wherein, the wiring harness assembly 1 includes a cable harness 11 and a first sealing body 12, the first sealing body 12 is sleeved on the cable harness 11, and the inner wall of the first sealing body 12 is provided with a first annular protrusion 121, the first annular protrusion 121 and the shielding layer 112 of the cable harness 11 are abutted, the outer wall of the first sealing body 12 is provided with a second annular protrusion 122, the second annular protrusion 122 and the inner wall of the shell 2 are abutted, the outer wall of the shell 2 is provided with an annular groove 21, and a sealing ring 3 is embedded in the annular groove 21.

[0038] In this embodiment, when the integrated resolver wiring harness is installed on the chassis, the sealing ring 3 can fit tightly with the contact surface of the chassis to form an effective external sealing barrier, effectively preventing external moisture, dust or other contaminants from entering the chassis through the gaps, thereby protecting the electrical components inside the chassis from damage.

[0039] The first annular protrusion 121 is provided on the inner wall of the first sealing body 12 and abuts against the shielding layer 112 of the cable harness 11. This design not only helps to secure the cable harness 11 and prevent it from moving within the housing 2, but also improves the sealing performance of the integrated resolver harness, preventing external contaminants such as moisture and dust from penetrating into the resolver harness through this gap, thereby protecting the electrical performance and safety of the cable harness 11. Secondly, the design of the second annular protrusion 122 further enhances the sealing between the cable harness 11 and the housing 2, preventing moisture, dust, etc. from penetrating into the integrated resolver harness through this path.

[0040] See also Figure 2 and Figure 3As shown, a shielding ring 4 is also provided in the housing 2. From right to left, the cable harness 11, the first wire sealing body 12, and the shielding ring 4 are sequentially installed in the receiving hole of the housing 2. Specifically, a limiting portion 41 is provided in the shielding ring 4. One end of the shielding layer 112 extends outward through the housing 2, and the other end of the shielding layer 112 abuts against the side wall of the limiting portion 41. At least a portion of the shielding ring 4 is embedded in the gap between the shielding layer 112 and the first wire sealing body 12. The introduction of the shielding ring 4 provides a limit for the wiring harness assembly 1, so that the shielding ring 4 can limit the movement range of the first wire sealing body 12 to a certain extent, preventing it from falling off or shifting due to external forces. At the same time, at least a portion of the shielding ring 4 is embedded in the gap between the shielding layer 112 and the first wire sealing body 12, further enhancing the connection strength and sealing between the cable harness 11, the first wire sealing body 12, and the shielding ring 4.

[0041] See also Figure 4 As shown, a stopper 22 is provided at the left end of the housing 2, and a first annular platform 123 is provided on the outer wall of the first wire sealing body 12. The side wall of the stopper 22 contacts the first annular platform 123. A second annular platform 42 is provided on the outer wall of the shielding ring 4, and the right end of the first wire sealing body 12 contacts the second annular platform 42. Specifically, the stopper 22 at the left end of the housing 2 cooperates with the shielding ring 4 to limit the position of the first wire sealing body 12, thereby preventing the first wire sealing body 12 from falling out of the housing 2.

[0042] Specifically, the first sealing body 12 is limited by the cooperation of the stopper 22 at the left end of the housing 2 and the shielding ring 4. This design significantly enhances the structural stability of the entire assembly. The side wall of the stopper 22 contacts the first annular table 123 of the first sealing body 12. At the same time, the second annular table 42 of the shielding ring 4 contacts the right end of the first sealing body 12, limiting the range of movement of the first sealing body 12, ensuring the secure installation of the first sealing body 12, and effectively preventing the first sealing body 12 from falling out of the housing 2. Secondly, the first sealing body 12 is used to fix and protect the cable harness 11. If the first sealing body 12 falls off or shifts, it may cause damage to the cable harness 11 or malfunction. The dual limitation of the stopper 22 and the shielding ring 4 can ensure that the first sealing body 12 always remains in the correct position, and the integrated rotary transformer harness can maintain stable function even when facing external forces such as vibration and impact.

[0043] See also Figures 6 to 8As shown, a through groove 43 is provided on the second annular table 42 of the shielding ring 4. The through groove 43 extends along the axis of the shielding ring 4 to the side wall of the shielding ring 4, and the through groove 43 is connected to the inner cavity of the shielding ring 4. A third annular table 23 and a limiting protrusion 24 formed by a portion of the third annular table 23 extending outward along the axis of the housing 2 are provided in the housing 2. The second annular table 42 and the third annular table 23 abut against each other, and the limiting protrusion 24 is embedded in the through groove 43. This design allows the limiting protrusion 24 of the housing 2 to be embedded in the through groove 43 when the third annular table 23 in the housing 2 abuts the second annular table 42 of the shielding ring 4. The cooperation between the through groove 43 and the limiting protrusion 24 prevents the shielding ring 4 from rotating about its axis within the housing 2, thereby ensuring the stability of the shielding ring 4 in the predetermined position.

[0044] See also Figure 5 As shown, the integrated rotary transformer wiring harness provided by the present invention further includes a support assembly 5, which is arranged in the accommodating hole. The support assembly 5 is used for allowing multiple cores 111 of the cable harness 11 to pass through so as to separate and fix the multiple cores 111.

[0045] Specifically, after the cable harness 11, the first sealing body 12 and the shielding ring 4 are sequentially installed in the shell 2, the multiple wire cores 111 are exposed by stripping off the outer sheath of the cable harness 11, and then installed into the support assembly 5. At this time, the support assembly 5 can effectively separate these wire cores 111 to prevent multiple wire cores 111 from being entangled with each other. The support assembly 5 can also fix each wire core 111 to prevent the wire core 111 from loosening during vibration or movement. Secondly, the support assembly 5 not only has the function of separating and fixing the wire cores 111, but also can seal each wire core 111 to prevent moisture, dust and other contaminants from entering the interior of the chassis.

[0046] Specifically, the support assembly 5 includes a support sheath 51 and a second wire sealing body 52. ​​A locking protrusion 511 is provided at one end of the support sheath 51. When the support sheath 51 is embedded in the shielding ring 4, the locking protrusion 511 cooperates with the through groove 43 to engage, and at least a portion of the second wire sealing body 52 is embedded in the support sheath 51. The support sheath 51 is provided with a plurality of first mounting holes 512 extending along the axis of the support sheath 51 and passing through both ends of the support sheath 51. One end of the second wire sealing body 52 is provided with a plurality of first protrusions 521, which are inserted into the first mounting holes 512. The other end of the second wire sealing body 52 is correspondingly provided with a plurality of second protrusions 522. The second wire sealing body 52 is provided with a plurality of second mounting holes 523 extending along the axis of the second wire sealing body 52, and each second mounting hole 523 passes through a first protrusion 521 and a second protrusion 522 coaxially disposed therewith.

[0047] See also Figure 5As shown, the integrated resolver wiring harness provided by the present invention also includes a pressure plate 6, which is provided with a plurality of third mounting holes 61. The plurality of third mounting holes 61 are provided in a one-to-one correspondence with the plurality of second protrusions 522 for the second protrusions 522 to pass through. Specifically, the pressure plate 6 and the support sheath 51 respectively secure the second wire seal 52 from the left and right sides of the second wire seal 52, thereby ensuring the secure installation of the second wire seal 52.

[0048] In this embodiment, at least one third annular protrusion 5231 is provided in the second mounting hole 523. The third annular protrusion 5231 surrounds the outer wall of the core 111 of the cable harness 11 and contacts the core 111 of the cable harness 11. This design enables each core 111 to be individually sealed, preventing moisture, dust, and other contaminants from entering the chassis through this path.

[0049] See also Figure 5 As shown, the utility model provides an integrated rotary transformer wiring harness further including a locking nut 7, a through hole 71 penetrating the wall thickness of the locking nut 7 is provided in the middle of the locking nut 7, at least a portion of the pressure plate 6 is passed through the through hole 71, and the through hole 71 is used for the core 111 of the cable harness 11 to pass through, and the locking nut 7 and the housing 2 are connected by threaded matching.
