Description

Technical Field

[0001] The utility model relates to the field of line connection, and more specifically to a rotational transformer wire harness connection structure. Background Art

[0002] Resolver wiring harnesses are mostly used in controllers. At present, there are two main ways to connect resolver connectors of new energy controllers on the market. One is mainly connected through special connectors. The controller end and the motor end are connected through the male and female heads of the special connector. The male and female heads are respectively connected to the resolver wiring harness and the plug, and then respectively connected with the plug on the controller PCBA board and the plug on the motor resolver. The other is to directly lead the wiring harness from the controller end to the motor end, seal it with a sealing gasket in the middle, and connect the two ends with the plug on the PCBA board and the plug on the motor resolver through plugs.

[0003] When the first solution uses dedicated male and female connectors, the male and female connectors must be equipped with wiring harnesses and plugs at the other end to connect to the PCBA and motor end of the controller, which results in higher costs; in the second solution, the sealing effect level is low and the structural reliability is poor; at the same time, when the existing resolver wiring harness is used for docking, it is composed of multiple twisted wiring harnesses as a whole. Therefore, when it is sealed, the existing sealing structure is difficult to ensure the fit and seal with the entire wiring harness, which leads to inadequate sealing. At the same time, it is difficult to achieve stable fixation of the entire wiring harness, which is not conducive to subsequent docking operations.

[0004] Therefore, the utility model proposes a rotational wiring harness docking structure. Utility Model Content

The inner surface of the limit cylinder body 8 is fixedly provided with an arc-shaped limit groove 10. The connecting bottom ring 9 is also fixedly connected to the surface of the upper pressure seat 1. The limit grooves 10 are arranged in multiple groups in a vertical arc along the inner surface of the limit cylinder body 8, and are arranged in a vertical spiral shape as a whole. The external limit cylinder structure 3 cooperates with the limit grooves 10 on its inner surface to achieve the effect of fitting and limiting the derived rotating transformer harness.

[0026] When the resolver wiring harness is led outward through the upper pressure seat 1, it passes through the upper pressure seat 1 and enters the outer limiting cylinder structure 3. When it is led outward through the outer limiting cylinder structure 3, the outer surfaces of multiple groups of single wiring harnesses in the resolver wiring harness are fitted and led out along the limiting grooves 10 on the inner surface of the limiting cylinder body 8. Through the limiting grooves 10, it can be effectively fitted and fixed with the outer surface of the resolver wiring harness, thereby ensuring the sealing and the structural reliability of the resolver wiring harness, and avoiding the wiring harness from twisting and loosening.

[0027] The bottom end of the upper press seat 1 is fixedly connected with a first positioning portion 5 and a second positioning portion 6, and the first positioning portion 5 and the second positioning portion 6 are distributed in sequence from the outside to the inside on the bottom surface of the upper press seat 1, and the two are arranged in an "H" shape as a whole. The side section of the outer positioning seat 4 is arranged in an "L" shape, corresponding to the arrangement below the first positioning portion 5, and the first positioning portion 5 is embedded in the inner position of the outer positioning seat 4 at the same time, and the second positioning portion 6 is embedded in the inner position of the lower press seat 2. The upper press seat 1 and the lower press seat 2 are matched with the outer positioning seat 4 through two groups of positioning portion structures. When the upper and lower press seat structures are matched and matched, the two groups of positioning portion structures at the bottom of the upper press seat 1 are correspondingly embedded in the inner positions of the outer positioning seat 4 and the lower press seat 2, thereby ensuring the stable fitting of the upper and lower press seat structures, and at the same time, the second positioning portion 6 is used to achieve the effect of limiting and fixing the inner limit seat structure 7 from above.

The sealing protrusions 12 are configured as longitudinal strip protrusions along the inner surface of the limit seat body 11, and the sealing protrusions 12 are configured as silicone strips. The limit seat body 11 cooperates with the sealing protrusions 12 on its inner surface to achieve the effect of enhancing the connection sealing between the upper and lower pressure seat structures.

[0029] Multiple groups of lead-out tubes 14 are arranged along the surface of the lead-out portion 13 , and the lead-out tubes 14 are used to separate and lead out multiple groups of wire harnesses in the resolver wire harness, and simultaneously to individually limit and fix multiple groups of wire harnesses in the resolver wire harness.
