[0001] This utility model relates to the field of automotive electronic connector technology, specifically to an automotive wiring harness terminal connector. Background Technology

[0002] Automotive wiring harness terminal connectors are the "nerve nodes" of automotive electrical systems. They consist of conductive terminal bodies (such as copper, copper alloys, and aluminum) and insulating sleeves (plastic or rubber). Their core functions include electrical connection and signal transmission, as well as protection and safety. They enable stable transmission of power and data between devices such as the engine, headlights, and audio systems, preventing short circuits, vibration damage, and environmental corrosion, thus ensuring driving safety.

[0003] The prior art (Chinese patent with publication number CN214227163U, publication date 2021-09-17) discloses an anti-detachment type automotive wiring harness terminal connector, comprising a first housing, a second housing, and a fixing frame. A first fixing member is embedded and fixed at one end of the first housing, and a third fixing member is embedded and fixed at the end of the first housing opposite to the first fixing member. A second fixing member is embedded and fixed at one end of the second housing, and a fourth fixing member is embedded and fixed at the end of the second housing opposite to the second fixing member. Both the fourth fixing member and the third fixing member have a first external thread engraved on them, and a second nut is rotatably installed on the first external thread. Both the first fixing member and the second fixing member have a second external thread engraved on them, and a first nut is rotatably installed on the second external thread. A limit frame is welded to the bottom surface of the inner wall of the first housing, and a first limit rod is fitted to the top surface of the inner wall of the second housing. A limit groove is formed in the fixing frame.

[0004] While existing technologies offer advantages such as ease of operation, secure fixation, and superior practicality, single-specification connectors cannot simultaneously meet the needs of power, signal, and radio frequency transmission. Furthermore, the male and female ends of the connectors are prone to loosening during assembly, resulting in low stability during insertion and removal.

[0005] Therefore, we propose an automotive wiring harness terminal connector to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this utility model is to provide an automotive wiring harness terminal connector to solve the problems mentioned in the background art, such as the inability of a single-specification connector to simultaneously meet the power, signal and radio frequency transmission requirements, and the easy loosening of the male and female ends of the connector during assembly, resulting in low insertion and removal stability of the terminals.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness terminal connector, comprising a female connector housing and a male connector housing for assembling the connector, wherein a connector inner core body is disposed inside the female connector housing, and a PIN protection plate is disposed inside the male connector housing, and a pull rod is slidably disposed on the outer side of the female connector housing, thereby achieving assembly locking between the female connector housing and the male connector housing through the sliding of the pull rod.

[0008] Furthermore, the connector core body is provided with an anti-misalignment groove to ensure correct assembly with the mating end, and the connector core body can be divided into 39 holes and 68 holes.

[0009] Furthermore, when the connector core body has 68 holes, a Fakra module is provided inside the connector core body to ensure stable insertion and removal of high-frequency terminals, and the Fakra module is injection molded from glass fiber reinforced polyester.

[0010] Furthermore, a sealing ring for waterproofing is provided between the connector female end shell and the connector inner core body, and the sealing ring is made of silicone rubber by extrusion molding.

[0011] Furthermore, the male end of the connector housing is provided with a sealing gasket to maintain electrical contact stability, and the sealing gasket is extruded from silicone rubber.

[0012] Furthermore, both the female connector housing and the male connector housing are slidably provided with TPA locking keys for secondary locking, and the TPA locking keys are injection molded from glass fiber reinforced polyester.

[0013] Furthermore, the female connector housing is slidably provided with a pull rod, and a slider is fixedly connected to the inner side of the pull rod. The male connector housing is provided with a limiting groove on the outer side, and the limiting groove is set in an inclined structure. When the female connector housing and the male connector housing are assembled, the slider is slidably disposed inside the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The connector female shell, connector male shell, and connector inner core are all injection molded from glass fiber reinforced polyester, which gives the connector female shell impact and vibration resistance, thereby providing fixed position support for the terminal connection. At the same time, the connector female shell can further ensure correct assembly with the mating end through the anti-misalignment grooves on its side.

[0016] 2. After the terminal is inserted into the connector, the TPA locking key is nested inside the connector. At this time, the TPA locking key can engage with the terminal slot to lock it a second time, thereby further improving the stability of terminal insertion and removal.

[0017] 3. The sealing ring formed by extrusion of silicone rubber can not only ensure the stability of electrical contact between the machine and the connector, but also seal the connector to achieve a waterproof effect. At the same time, the sealing gasket formed by extrusion of silicone rubber can also play a waterproof role between the sheet metal and the connector.

[0018] 4. The Fakra module provides fixed position support for terminal connections, and the Fakra module is equipped with a secondary locking structure to further ensure the stability of high-frequency terminal insertion and removal.

[0019] 5. After the initial assembly between the female connector housing and the male connector housing is completed, the slider on the inner side of the pull rod on the female connector housing can be inserted into the limiting slot on the outer side of the male connector housing. At this time, pushing the pull rod inward will cause the slider to slide along the limiting slot until the slider is located on the side of the limiting slot. Through the cooperation between the limiting slot and the slider, the pull rod can be limited, thereby locking the aligned female connector housing and the male connector housing and preventing them from becoming loose.

[0031] Example 1: As Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 9 The technical solution shown herein provides the following technical solution: an automotive wiring harness terminal connector, disclosed in two models with 39 holes and 68 holes to meet different usage requirements, while a secondary locking structure ensures high-frequency terminal insertion and removal stability: including a connector female end shell 1 and a connector male end shell 3 for assembling the connector, the connector female end shell 1 has a connector inner core body 2 inside, and the connector male end shell 3 has a PIN pin protection plate 7 inside, the connector inner core body 2 has an anti-misalignment groove to ensure correct assembly with the mating end, and the connector inner core body 2 can be divided into 39 holes and 68 holes. When there are 68 holes, the connector inner core body 2 is provided with a Fakra module 11 to ensure stable insertion and removal of high-frequency terminals. The Fakra module 11 is injection molded from glass fiber reinforced polyester. A sealing ring 6 for waterproofing is provided between the connector female shell 1 and the connector inner core body 2. The sealing ring 6 is extruded from silicone rubber. A sealing gasket 8 for maintaining electrical contact stability is provided on the end side of the connector male shell 3. The sealing gasket 8 is extruded from silicone rubber. Both the connector female shell 1 and the connector male shell 3 are slidably provided with TPA locking keys 5 for secondary locking.

[0032] The connector female housing 1, connector male housing 3, and connector inner core body 2 are all injection molded from glass fiber reinforced polyester, giving the connector female housing 1 impact and vibration resistance, thus providing fixed position support for the terminal connection. Simultaneously, the connector female housing 1, through its side anti-misalignment grooves, further ensures correct assembly with the mating end. After the terminal is inserted into the connector, the TPA locking key 5 is nested inside the connector. At this time, the TPA locking key 5 can engage with the terminal slot, thereby locking it a second time and further improving the stability of terminal insertion and removal. The sealing ring 6, formed by extrusion of silicone rubber, can ensure the stability of electrical contact between the connector and the machine, while also sealing the connector, thus providing waterproofing. Similarly, the sealing gasket 8, also formed by extrusion of silicone rubber, provides waterproofing between the sheet metal and the connector. The Fakra module 11 provides fixed position support for the terminal connection, and the Fakra module 11 is equipped with a secondary locking structure to further ensure the stability of high-frequency terminal insertion and removal.

The pull rod 4 is slidably disposed on the outer side of the female connector housing 1, and the assembly locking between the female connector housing 1 and the male connector housing 3 is achieved by sliding the pull rod 4. The female connector housing 1 is slidably disposed on the pull rod 4, and a slider 9 is fixedly connected to the inner side of the pull rod 4. A limiting groove 10 is opened on the outer side of the male connector housing 3, and the limiting groove 10 is arranged in an inclined structure. When the female connector housing 1 and the male connector housing 3 are assembled, the slider 9 is slidably disposed inside the limiting groove 10.

[0034] After the initial assembly between the female connector housing 1 and the male connector housing 3 is completed, the slider 9 inside the pull rod 4 on the female connector housing 1 can be inserted into the limiting groove 10 on the outside of the male connector housing 3. At this time, pushing the pull rod 4 inward will cause the slider 9 to slide along the limiting groove 10 until the slider 9 is located on the side of the limiting groove 10. Through the mutual cooperation between the limiting groove 10 and the slider 9, the pull rod 4 can be limited, thereby locking the aligned female connector housing 1 and the male connector housing 3 and preventing them from becoming loose.
