[0030] Figure 1 It is a three-dimensional diagram of an embodiment of the utility model, referring to Figure 1 One embodiment of the utility model provides a car door handle, which is used to enable the car door handle to be externally connected to a power source and a signal to realize some intelligent operations of the car door handle, such as sensing, luminescence, automatic telescopic and the like.

[0031] Furthermore, the wiring harness connector of the utility model includes a door handle assembly 100, which is the main structure of the automobile door handle. The door handle assembly 100 is provided with a wiring harness 200. Figure 1 , Figure 2 The wiring harness 200 is provided with a connector 300, and the connector 300 is provided with a sheath 400. The wiring harness 200 is connected to the outside through the connector 300, and the sheath 400 serves as a protective cover.

[0032] Further, refer to Figure 3 The door handle assembly 100 is provided with a mounting groove 110, and the mounting groove 110 has a connector groove 111 and a sheath groove 112, which are used to respectively install the connector 300 and the sheath 400.

[0033] Further, refer to Figure 3 , Figure 5 A sheath limiting opening 120 is provided on the sheath slot 112 , and a sheath limiting plate 420 is provided on the sheath 400 . The sheath limiting opening 120 limits the sheath limiting plate 420 .

[0034] Furthermore, a locking protrusion 121 is provided on the sheath limiting opening 120 , and a locking surface 421 is provided on the sheath limiting plate 420 . The locking protrusion 121 presses against the locking surface 421 and applies a force on the sheath 400 toward the connector 300 .

[0035] During actual installation, one end of the wiring harness 200 is connected to the electronic components and control components in the door handle assembly 100, and the other end is connected to the connector 300. The sheath 400 is connected to the connector 300, and then the connector 300 and the sheath 400 are inserted into the connector slot 111 and the sheath slot 112 of the installation slot 110. In this process, the sheath limiting plate 420 of the sheath 400 is aligned with the sheath limiting opening 120 of the door handle assembly 100, and the locking protrusion 121 of the sheath limiting opening 120 is supported against the locking surface 421 of the sheath limiting plate 420. In this way, the sheath 400 can be supported by the locking protrusion 121, ensuring that there is no looseness between the sheath 400 and the connector 300, and ensuring the reliability of the wiring harness connection.

[0036] Some embodiments, see Figure 1 , Figure 4A sheath groove convex strip 130 is provided in the sheath groove 112 , and the sheath groove convex strip 130 is used to cooperate with the sheath groove 112 to clamp the sheath 400 , so as to ensure that the sheath 400 is firmly installed in the sheath groove 112 .

[0037] In this embodiment, optionally, refer to Figure 1 A sheath outer boss 430 is arranged on the outer side of the sheath 400 , and the sheath groove convex strip 130 clamps the sheath outer boss 430 to ensure that the sheath groove convex strip 130 can clamp the sheath 400 .

[0038] In this embodiment, optionally, refer to Figure 5 The locking surface 421 includes a locking surface inclined surface portion 422. When the sheath limiting plate 420 of the sheath 400 is aligned with the sheath limiting opening 120 of the door handle assembly 100, first align the locking surface inclined surface portion 422 with the locking protrusion 121, and then press the sheath 400 so that the locking protrusion 121 gradually clamps the sheath 400 along the inclined surface of the locking surface inclined surface portion 422, making the installation of the sheath 400 easier.

[0039] Some embodiments, see Figure 4 , Figure 5 The connector 300 is provided with a connector plug interface 310, and the sheath 400 is provided with a sheath plug portion 410. The sheath plug portion 410 is plugged into the connector plug interface 310, and the sheath plug portion 410 is provided with a terminal through hole 412, that is, the connection method between the terminal of the wiring harness 200 and the sheath 400 is a plug-in connection.

[0040] In this embodiment, optionally, refer to Figure 5 A guide pin bevel 413 is provided on the edge of the terminal through-hole 412. When the sheath plug-in portion 410 of the sheath 400 is plugged into the connector plug-in interface 310 of the connector 300, the design of the guide pin bevel 413 enables the terminal of the wiring harness 200 to be more easily aligned with the terminal through-hole 412 along the guide pin bevel 413 for terminal wiring.

[0041] In some embodiments, a connector plug interface snap-in boss 311 is provided in the connector plug interface 310, and a sheath plug portion snap-in groove 411 is provided on the sheath plug portion 410. The connector plug interface snap-in boss 311 and the sheath plug portion snap-in groove 411 increase the friction between the connector plug interface 310 and the sheath plug portion 410, further ensuring a stable connection between the connector 300 and the sheath 400.

[0042] Some embodiments, see Figure 3 , Figure 4A connector plug-in boss 140 is provided on the connector slot 111, and a connector linear plug-in groove 320 is provided on the connector 300. The connector linear plug-in groove 320 clamps the connector plug-in boss 140. After the connector linear plug-in groove 320 of the connector 300 is aligned with the connector plug-in boss 140 of the mounting groove 110, the connector 300 is installed into the mounting groove 110 along the direction of the connector linear plug-in groove 320 to ensure that the connector 300 is firmly installed.

[0043] During actual installation, after the connector 300 and the sleeve 400 are connected together, the connector linear plug-in groove 320 of the connector 300 is aligned with the connector plug-in boss 140 of the door handle assembly 100 for connection, and then the sleeve limit opening 120 limits the sleeve limit plate 420 of the sleeve 400.

[0044] In this embodiment, optionally, refer to Figure 4 The connector linear plug-in slot 320 is an inclined linear slot structure, so when the connector 300 is installed along the connector linear plug-in slot 320, the wiring harness 200 can be prevented from being pulled or even torn off.

[0045] Some embodiments, see Figure 1 , Figure 3 A connector block 150 is provided on the connector slot 111 , and the connector block 150 cooperates with the connector slot 111 to clamp the connector 300 , thereby ensuring that the connector 300 is installed more firmly in the installation slot 110 .
