According to the wire harness connection structure of the embodiment of the utility model, since the wire harness 4 is passed through the first hole 12, the gasket 3 and the second hole 21 and is connected to the connector housing 2, the outer peripheral wall of the wire harness 4 abuts against the gasket 3, so that the mounting gap between the wire harness 4 and the connector housing 2 can be sealed, and since the gasket 3 abuts between the connector housing 2 and the electric control housing 1, the mounting gap between the connector housing 2 and the electric control housing 1 can be sealed. Therefore, the wire harness connecting structure of the embodiment of the utility model can seal the mounting gaps among the electric control shell 1, the connector shell 2 and the wire harness 4 by arranging the single sealing gasket 3, thereby simplifying the sealing connecting structure of the wire harness connecting structure, being convenient for assembly and having better sealing effect.
It is understood that the wire harness 4 is a high voltage wire harness 4, and the material of the wire harness 4 may be copper, aluminum or other conductive metal. For example, the wire harness 4 may be cylindrical or square, and the structure of the cross section of the wire harness 4 is not particularly limited in this application.
Alternatively, the gasket 3 is an elastic rubber gasket, and the gasket 3 is compressed after the harness connecting structure is installed, so that the sealing performance between the electronic control housing 1, the connector housing 2, and the harness 4 can be improved.
In some embodiments, as shown in fig. 1 to 3, the wire harness 4 includes a main body section 41 and a connection section 42 connected, the main body section 41 is penetrated through the first hole 12, the connection section 42 is penetrated through the sealing pad 3 and the second hole 21, the cross section of the connection section 42 is smaller than that of the main body section 41, one end of the main body section 41 adjacent to the connection section 42 defines a first step surface 411, and the first step surface 411 abuts against the sealing pad 3. It will be appreciated that the main body section 41 and the connecting section 42 may be coaxially arranged, and since the cross section of the connecting section 42 is smaller than that of the main body section 41, a first stepped surface 411 may be formed on the end surface of the main body section 41 adjacent to the connecting section 42, and the first stepped surface 411 elastically abuts against the gasket 3 to increase the sealing contact area between the wire harness 4 and the connector housing 2, thereby improving the waterproof sealing effect between the wire harness 4 and the connector housing 2.
Alternatively, as shown in fig. 1 and 2, the gasket 3 is provided with a third hole 31, and an inner peripheral wall of the third hole 31 abuts against an outer peripheral wall of the wire harness 4. It will be appreciated that the aperture of the third hole 31 may be slightly smaller than the aperture of the connecting section 42, and when the connecting section 42 is inserted into the third hole 31, the sealing pad 3 has a certain elasticity, so that the third hole 31 is spread and the inner peripheral wall of the third hole 31 is elastically abutted with the outer peripheral wall of the wire harness 4, thereby further increasing the sealing contact area between the wire harness 4 and the connector housing 2 and improving the waterproof sealing effect between the wire harness 4 and the connector housing 2.

In addition, the wire harness 4 is connected with the connector shell 2 in a clamping manner, so that the wire harness connecting structure can be conveniently assembled, and the structure is simple, and is convenient to process and manufacture.
Alternatively, as shown in fig. 1 to 3, the connecting section 42 includes a first section 421 and a second section 422, the cross section of the first section 421 is smaller than that of the second section 422, one end of the first section 421 (e.g., the upper end of the first section 421 in fig. 2) is connected to the main body section 41, the other end of the first section 421 (e.g., the lower end of the first section 421 in fig. 2) is connected to the second section 422 and defines a second step surface 4231, the second step surface 4231 forms a mating portion 423, and the clamping portion 22 abuts against the second step surface 4231. It will be appreciated that the cross section of the first section 421 is smaller than the cross sections of the main body section 41 and the second section 422, so that the first section 421 forms an annular groove structure, and the clamping portion 22 abuts against the second step surface 4231, so that the wire harness 4 can be limited to move upwards, and the wire harness 4 can be axially positioned, so that the wire harness 4 can be conveniently fixed, and the assembly efficiency of the wire harness connecting structure is improved.

It can be understood that the hook 221 is integrally formed with the connector housing 2, the hook 221 is inclined toward the wall surface of the first section 421 and has a certain elasticity, and after the wire harness 4 is threaded into the second hole 21, the hook 221 can clamp the first section 421, so as to improve the connection stability of the wire harness 4.
For example, as shown in fig. 2 and 5, the number of the clamping portions 22 is plural, and the plurality of clamping portions 22 are arranged at intervals along the circumferential direction of the second hole 21, so that the uniformity of the stress of the wire harness 4 can be improved, the problem that the wire harness 4 slides relative to the second hole 21 is further avoided, and the connection stability of the wire harness 4 is improved.
Alternatively, as shown in fig. 1 and 4, a mating surface 23 is provided on one side of the connector housing 2 adjacent to the electric control housing 1, a mounting groove 24 is provided on the mating surface 23, the gasket 3 is provided in the mounting groove 24, and the mating surface 23 and the gasket 3 are both abutted against the inner wall surface of the electric control housing 1. For example, the cross section of the gasket 3 is rectangular, and the cross section of the mounting groove 24 is also rectangular. The gasket 3 is placed into the mounting groove 24 to locate the position of the gasket 3. The matching surface 23 and the sealing gasket 3 are propped against the inner wall surface of the electric control shell 1, so that the sealing effect between the electric control shell 1 and the connector shell 2 can be improved.
For example, the mating surface 23 and the inner wall surface of the electric control housing 1 can be fixed together by means of bolts, screws, self-tapping rivets or glue bonding.
An electrical control system of another embodiment of the present utility model includes the wiring harness connection structure of the present utility model.
For example, the electric control housing 1 may be an outer housing of a power battery, an electric drive or an energy storage device. The connector housing 2 is an outer housing of a high voltage connector, and the harness 4 is a high voltage harness 4.
According to the electric control system of the embodiment of the utility model, since the wire harness 4 is passed through the first hole 12, the gasket 3 and the second hole 21 and is connected to the connector housing 2, the outer peripheral wall of the wire harness 4 abuts against the gasket 3, so that the installation gap between the wire harness 4 and the connector housing 2 can be sealed, and since the gasket 3 abuts between the connector housing 2 and the electric control housing 1, the installation gap between the connector housing 2 and the electric control housing 1 can be sealed. Therefore, the wire harness connecting structure of the electric control system can seal the mounting gaps among the electric control shell 1, the connector shell 2 and the wire harness 4 by arranging the single sealing gasket 3, so that the sealing connecting structure of the wire harness connecting structure is simplified, the assembly is convenient, and the sealing effect is good.
