[0024] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model. Example

[0025] like Figure 1-6The image shows the first embodiment of this utility model, which provides a quick connector for automotive wiring harnesses, including a cable 100 for signal transmission, a male plug 200 including a first housing 210 fixed to one end of the cable 100, a first insulator 220 located inside the cavity of the first housing 210, pins 230 located inside the cavity of the first insulator 220, and a positioning block 240 fixed to the inner wall of the first insulator 220, and a female plug 300 including a second housing 310 fixed to the other end of the cable 100, a second insulator 320 located inside the cavity of the second housing 310, and an opening... The protective assembly 400 includes a through hole 330 on the surface of the second insulator 320, an insertion hole 340 located in the cavity of the through hole 330, and a positioning groove 350 formed on the surface of the second insulator 320. The protective assembly 400 includes a plug 410 for sealing the male plug 200 and the female plug 300, an external threaded protective sleeve 420 fixedly connected to the first housing 210, an internal threaded protective sleeve 430 sleeved on the surface of the second insulator 320, a sealing ring 440 located in the cavity of the internal threaded protective sleeve 430 and sleeved on the surface of the second insulator 320, and a connecting strip 450 for fixing the plug 410.

[0026] like Figure 1-6 As shown, the positioning block 240 of the male plug 200 cooperates with the positioning groove 350 of the female plug 300. During wire harness connection, the positioning block 240 extends into the inner cavity of the positioning groove 350, enabling a sliding connection. Compared to traditional plastic clips, this positioning method effectively reduces the risk of wear and aging caused by frequent insertion and removal of plastic clips. Through mechanical sliding positioning, precise docking of the male plug 200 and female plug 300 is ensured, allowing the pin 230 to be accurately inserted into the socket 340. This avoids problems caused by inaccurate positioning affecting the connection effect, significantly improving the reliability of the connection. The external threaded protective sleeve 420 and the internal threaded protective sleeve 430... The threaded connection further enhances the stability of the connection. Compared with plastic snaps, the threaded connection has better anti-aging performance and higher connection strength. During long-term use, even if subjected to certain vibrations or external pulling forces, the threaded connection can still maintain a tight fit, greatly reducing the risk of connection interruption due to loosening. At the same time, the threaded connection structure can still maintain good connection performance after multiple insertions and removals, and will not easily lose elasticity due to aging like plastic snaps. The plug 410 and sealing ring 440 in the protective component 400 can effectively prevent dust, moisture and other impurities from entering the connector, avoiding aging and damage to the connection components caused by impurity corrosion. Example

[0027] Reference Figure 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, two plugs 410 and two connecting strips 450 are provided. One end of the connecting strip 450 is fixedly connected to the plug 410, and the other end is fixedly connected to the first housing 210 and the second housing 310 respectively. The two plugs 410 respectively cover the ends of the male plug 200 and the female plug 300 away from the cable 100.

[0029] The first insulator 220 is fixedly connected to the inner wall of the first housing 210, one end of the pin 230 is fixedly connected to the cable 100, and the other end passes through the inner cavity of the first insulator 220.

[0030] One end of the socket 340 is fixedly connected to the cable 100, and the other end of the socket 340 passes through the inner cavity of the through hole 330 and is fixedly connected to the inner wall of the through hole 330. The second insulator 320 is fixedly connected to the inner wall of the second housing 310.

[0031] When used for wire harness connection, the end of the second insulator 320 away from the second housing 310 extends into the inner cavity of the first insulator 220 and is inserted into the inner cavity of the first insulator 220, and the end of the pin 230 away from the cable 100 extends into the inner cavity of the socket 340 and is inserted into the inner cavity of the socket 340.

[0032] When used for wire harness connection, the positioning block 240 extends into the inner cavity of the positioning groove 350 and is slidably connected to the inner cavity of the positioning groove 350, and the external thread protective sleeve 420 extends into the inner cavity of the internal thread protective sleeve 430 and is threadedly connected to the inner cavity of the internal thread protective sleeve 430.

[0033] The first insulator 220 is located in the inner cavity of the external thread protective sleeve 420 and is fixedly connected to the inner wall of the external thread protective sleeve 420.

[0034] Both the second outer shell 310 and the first outer shell 210 are made of flame-retardant engineering plastic, and the pin 230 and the socket 340 are made of copper alloy material with gold plating. The pin 230 is solid and the socket 340 is hollow.

[0035] like Figure 1-6 As shown, the cable 100 serves as a carrier for signal transmission, providing a channel for signal transmission between various automotive components. The first outer shell 210 of the male plug 200 is fixed to one end of the cable 100, protecting the internal structure. The first insulator 220 is located inside the first outer shell 210, ensuring electrical insulation of the pin 230. One end of the pin 230 is fixedly connected to the cable 100, and the other end extends through the inner cavity of the first insulator 220, facilitating docking with the female plug 300 to achieve signal transmission. The positioning block 240 is fixed to the inner wall of the first insulator 220 for positioning during docking.

[0036] In the female plug 300, the second outer shell 310 is fixed to the other end of the cable 100, the second insulator 320 is inside the second outer shell 310, and its surface has a through hole 330. The socket 340 is located inside the through hole 330. One end of the socket 340 is fixedly connected to the cable 100, and the other end passes through the through hole 330. The positioning groove 350 is formed on the surface of the second insulator 320 and cooperates with the positioning block 240 of the male plug 200.

[0037] When connecting wire harnesses, the end of the second insulator 320 away from the second housing 310 extends into the inner cavity of the first insulator 220 and is inserted. At the same time, the end of the pin 230 away from the cable 100 extends into the inner cavity of the socket 340 and is inserted, thereby realizing the electrical connection between the cables 100 and completing signal transmission. During the docking process, the positioning block 240 extends into the inner cavity of the positioning groove 350 and slides to ensure that the male plug 200 and the female plug 300 are accurately docked, avoiding misalignment and damage to the pin 230 and the socket 340. The external thread protective sleeve 420 extends into the inner cavity of the internal thread protective sleeve 430 and is threaded to further reinforce the connection between the male plug 200 and the female plug 300.

[0038] When in use, cable 100 is used for signal transmission, male plug 200 is fixed to one end of cable 100, and female plug 300 is fixed to the other end of cable 100. Before connection, plugs 410 are respectively covered on the ends of male plug 200 and female plug 300 away from cable 100 and fixed by connecting strap 450 to play a protective role.

[0039] When wire harness connection is required, the male plug 200 and the female plug 300 are connected. At this time, the end of the second insulator 320 away from the second housing 310 extends into the inner cavity of the first insulator 220 and is inserted. At the same time, the end of the pin 230 away from the cable 100 extends into the inner cavity of the socket 340 and is inserted. Both the pin 230 and the socket 340 are made of copper alloy and have gold-plated surfaces to ensure good conductivity, thereby realizing signal transmission at both ends of the cable 100.

[0040] During the docking process, the positioning block 240 extends into the inner cavity of the positioning groove 350 and slides in connection. The cooperation between the positioning block 240 and the positioning groove 350 plays a positioning role, ensuring that the pin 230 can be accurately inserted into the socket 340, and avoiding poor connection due to misalignment.

[0041] The external threaded protective sleeve 420 extends into the inner cavity of the internal threaded protective sleeve 430 and is threadedly connected. This threaded connection not only achieves mechanical fixation of the male plug 200 and the female plug 300, but also enhances the stability of the connection. At the same time, the sealing ring 440, which is sleeved on the surface of the second insulator 320, is located in the inner cavity of the internal threaded protective sleeve 430. When the external threaded protective sleeve 420 and the internal threaded protective sleeve 430 are tightened, the sealing ring 440 is squeezed, which plays a sealing role and prevents dust, moisture and other substances from entering the connector and affecting the electrical performance.
