[0029] In some embodiments of this application, a female connector 1 is provided, as shown in the reference... Figures 1 to 14 The female connector 1 includes a body 10 and a locking element 20.

[0030] Reference Figures 1 to 11 The main body 10 has a first channel 110 for inserting a power terminal 2 and a second channel 120 for inserting a signal terminal 3. The first channel 110 and the second channel 120 respectively penetrate the main body 10 along a first direction X, and the first channel 110 and the second channel 120 are spaced apart along a second direction Y. (Refer to...) Figure 1 The main body 10 has a first surface 101 and a second surface 102 arranged opposite each other along a third direction Z, a third surface 103 and a fourth surface 104 arranged opposite each other along a second direction Y, and a fifth surface 105 and a sixth surface 106 arranged opposite each other along a first direction X, wherein the first direction X, the second direction Y and the third direction Z intersect each other in pairs, as shown in the figure. Figures 1 to 14 In the embodiment shown, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other. Specifically, the first direction X is parallel to the length direction of the body 10, the second direction Y is parallel to the width direction of the body 10, and the third direction Z is parallel to the thickness direction of the body 10.

[0031] Reference Figure 1 , Figure 3 , Figures 5-8 as well as Figures 11-12 The main body 10 includes a first limiting part 130 disposed in the first channel 110. The first limiting part 130 can restrict the movement of the power terminal 2 along the first direction X. Specifically, the first limiting part 130 can restrict the movement of the power terminal 2 along the first direction X in the first channel 110. (Refer to...) Figure 2 , Figure 4 , Figures 9-10 The main body 10 also includes a second limiting part 140 disposed in the second channel 120. The second limiting part 140 can limit the movement of the signal terminal 3 along the first direction X. Specifically, the second limiting part 140 can limit the movement of the signal terminal 3 along the first direction X in the second channel 120.

[0032] Reference Figures 1-4 as well as Figures 13-14 The locking member 20 includes a body 21 and a first locking part 22 and at least two second locking parts 23 disposed on the body 21. The body 21 is disposed on the first surface 101 of the main body 10, specifically as follows: Figure 13 and Figure 14 In the embodiment shown, a first locking part 22 and at least two second locking parts 23 are disposed on the side of the body 21 facing the body 10 along a third direction Z, and the first locking part 22 and at least two second locking parts 23 are spaced apart along a second direction Y, as shown in the figure. Figure 1 , Figure 3 as well as Figure 6 The first locking part 22 is inserted into the first channel 110, as shown in the reference. Figure 3 The second locking part 23 is inserted into the second channel 120.

[0033] Among them, reference Figure 6 , Figure 11 as well as Figure 12 The first locking part 22 can cooperate with the first limiting part 130 to lock the power terminal 2, see reference. Figure 3 and Figure 13 At least two second locking portions 23 are spaced apart along the second direction Y, and two adjacent second locking portions 23 along the second direction Y can clamp the signal terminal 3 to lock the signal terminal 3.

[0034] FAKRA connectors are primarily used in vehicle navigation systems, in-vehicle electronic instruments, 360-degree panoramic systems, and in-vehicle autonomous driving systems. FAKRA connectors consist of a female connector and a male connector that mate to achieve the transmission of both current and signals. However, existing female connectors cannot simultaneously meet the requirements for both electrical and signal transmission.

[0035] The female connector 1 provided in this application embodiment includes a main body 10 and a locking member 20. The main body 10 has a first channel 110 for inserting a power terminal 2 and a second channel 120 for inserting a signal terminal 3. The main body 10 is provided with a first limiting part 130 for restricting the movement of the power terminal 2 and a second limiting part 140 for restricting the movement of the signal terminal 3. The locking member 20 includes a main body 21 and a first locking part 22 and at least two second locking parts 23 disposed on the main body 21. The first locking part 22 is inserted into the first channel 110. The first locking part 22 can cooperate with the first limiting part 130 to lock the power terminal 2. The two adjacent second locking parts 23 can clamp the signal terminal to lock the signal terminal 3.

[0036] The opening of the first channel 110 and the second channel 120 allows the power terminal 2 and the signal terminal 3 to be integrated into the body 10 of the female connector 1, thereby improving space utilization. When the power terminal 2 is inserted into the first channel 110, the first limiting part 130 can be used to initially position and limit the power terminal 2, so that the power terminal 2 can be kept in the first channel 110. When the signal terminal 3 is inserted into the second channel 120, the second limiting part 140 can be used to initially position and limit the signal terminal 3, so that the signal terminal 3 can be kept in the second channel 120.

[0037] After the power terminal 2 is inserted into the first channel 110 and the signal terminal 3 is inserted into the second channel 120, the first locking part 22 of the locking member 20 is inserted into the first channel 110 and the second locking part 23 is inserted into the second channel 120. The first locking part 22 cooperates with the first limiting part 130 to lock the power terminal 2, thereby ensuring the installation stability of the power terminal 2 in the first channel 110. The two adjacent second locking parts 23 along the second direction Y can cooperate to clamp the signal terminal 3, thereby ensuring the installation stability of the signal terminal 3 in the second channel 120.

[0038] The primary limitation of the power terminal 2 in the first channel 110 is formed by the first limiting portion 130, ensuring that the power terminal 2 can be accurately inserted into the first channel 110. Combining the cooperation design of the first locking portion 22 and the first limiting portion 130, the locking of the power terminal 2 in the first channel 110 is formed, ensuring the installation stability of the power terminal 2 in the first channel 110. The primary limitation of the signal terminal 3 in the second channel 120 is formed by the second limiting portion 140, ensuring that the signal terminal 3 can be accurately inserted into the second channel 120. Combining the clamping and locking of the second locking portion 23 on the signal terminal 3, the installation stability of the signal terminal 3 in the second channel 120 is ensured. While integrating the power terminal 2 and the signal terminal 3 into the same female connector 1, the stability of current transmission and signal transmission is ensured, thereby ensuring the working stability of the female connector 1. Further, when the female connector 1 and the male connector are mated to form a FAKRA connector, the stability of the power terminal 2 and the signal terminal 3 docking with the male connector can be ensured, and the stability of current and signal transmission can be ensured. On the basis of meeting the miniaturization and lightweight design of the female connector 1, the use stability of the FAKRA connector is ensured.

[0039] In addition, the structural design in which the first channel 110 and the second channel 120 are arranged at intervals along the second direction Y can meet the spacing requirements between the power terminal 2 and the signal terminal 3, so that the FAKRA connector formed by mating the female connector 1 and the male connector can meet the requirements of 48V high voltage of customers.

[0040] In some embodiments, referring to Figure 1 、 Figures 3-5 and Figure 7 、 Figure 9 and Figure 11 the number of the first channels 110 is four, and the four first channels 110 are arranged at intervals in a "field" shape. One power terminal 2 is inserted into each first channel 110. The number of the second channels 120 is two, and the two second channels 120 are arranged at intervals along the second direction Y. One signal terminal 3 is inserted into each second channel 120, so that the female connector 1 provided in the embodiment of the present application forms a "4 + 2" - bit integrated connector.

[0041] In some embodiments, referring to Figure 6 、 Figures 12-14The first locking part 22 is provided with an abutment part 221, which can abut against the power terminal 2 to restrict the movement of the power terminal 2 along the first direction X. The structural design of the abutment part 221 allows the power terminal 2 to be limited in the first channel 110 after the power terminal 2 is inserted into the first channel 110. Combined with the restriction of the movement of the power terminal 2 by the first limiting part 130, the locking effect of the power terminal 2 in the first channel 110 can be further improved, ensuring the installation stability of the power terminal 2 in the first channel 110. Moreover, the structural design of the abutment part 221 abutting against the power terminal 2 can prevent the power terminal 2 from falling off or loosening, thereby ensuring the installation stability of the power terminal 2 in the first channel 110.

[0042] In some embodiments, refer to Figure 6 , Figures 12-14 The number of abutment portions 221 is at least one, and one abutment portion 221 corresponds to two power terminals 2. The abutment portions 221 are bent at opposite ends along the second direction Y to form first bent portions 2211, and a receiving cavity 2210 is defined between the two first bent portions 2211. (Refer to...) Figure 6 The abutment portion 221 abuts against the power terminal 2 via the first bent portion 2211 to restrict the movement of the power terminal 2 along the first direction X. Specifically, as follows... Figure 13 and Figure 14 In the embodiment shown, there are two abutment portions 221, which are spaced apart along the third direction Z, and one first bending portion 2211 corresponds to one power terminal 2.

[0043] In some embodiments, refer to Figure 6 as well as Figures 12-14 The first locking part 22 also includes a support part 222, which extends along the third direction Z. One end of the support part 222 is connected to the body 21. An abutment part 221 is disposed on the support part 222. There are two abutment parts 221, which are spaced apart along the third direction Z. The provision of the support part 222 can ensure the stability of the abutment part 221 in the first channel 110, thereby ensuring the abutment stability between the first bent part 2211 on the abutment part 221 and the power terminal 2.

[0044] In some embodiments, refer to Figure 6 , Figure 8 and Figure 12 The first limiting part 130 includes a first connecting end 131 and a first limiting end 132 disposed opposite to each other along the first direction X. The first connecting end 131 is connected to the main body 10, and the first limiting end 132 is suspended inside the first channel 110. (Refer to...) Figure 6The first limiting end 132 can abut against the power terminal 2 to restrict the movement of the power terminal 2 along the first direction X. Specifically, the first limiting part 130 is disposed between two power terminals 2 spaced apart along the second direction Y. The first limiting end 132 abuts against the two power terminals 2 respectively along the first direction X to restrict the movement of the power terminals 2 along the first direction X. Moreover, the structural design of the first limiting end 132 abutting against the power terminal 2 can prevent the power terminal 2 from falling off or loosening, thereby ensuring the installation stability of the power terminal 2 in the first channel 110. In addition, the structural design of the first limiting end 132 suspended in the first channel 110 can increase the overall elasticity of the first limiting part 130, thereby preventing the second limiting end 142 from damaging the power terminal 2 while the first limiting end 132 abuts against the power terminal 2, ensuring the service life and operational stability of the power terminal 2.

[0045] Reference Figure 6 and Figure 12 The first limiting end 132 is inserted into the receiving cavity 2210 to cooperate with the abutment portion 221 to lock the power terminal 2. The receiving cavity 2210 defined between the two first bending portions 2211 on the abutment portion 221, with its structural design cooperating with the first limiting end 132, allows the two first bending portions 2211 to restrict the first limiting end 132. This restricts the power terminal 2 while preventing the first limiting end 132 from shaking. Moreover, the first bending portions 2211 can also abut against the power terminal 2 to restrict its movement. Thus, the first bending portions 2211 and the first limiting end 132 cooperate to lock the power terminal 2 in the first channel 110, ensuring the installation stability of the power terminal 2 in the first channel 110 and the stability of current transmission.

[0046] In some embodiments, refer to Figure 6 , Figure 8 and Figure 12 The first limiting end 132 protrudes from opposite sides along the second direction Y to form protruding ridges 1321. The first limiting end 132 abuts against the power terminal 2 through the protruding ridges 1321 to restrict the movement of the power terminal 2 along the first direction X. The structural design of the protruding ridges 1321 allows the first limiting end 132 to abut against the power terminals 2 located on both sides simultaneously. While achieving the purpose of restricting the movement of the power terminal 2 along the first direction X, it also improves space utilization, thereby ensuring the miniaturization and lightweight design of the female connector 1.

[0047] In some embodiments, refer to Figure 6 Along the second direction Y, there is a gap between the protruding ridge 1321 and the adjacent first bend 2211.

[0048] In some embodiments, along the second direction Y, the protrusion 1321 abuts against the adjacent first bend 2211.

[0049] In some embodiments, refer to Figure 2 , Figures 9-10 The second limiting part 140 includes a second connecting end 141 and a second limiting end 142 disposed opposite to each other along the first direction X. The second connecting end 141 is connected to the main body 10, and the second limiting end 142 is suspended inside the second channel 120. The second limiting end 142 can abut against the signal terminal 3 to restrict the movement of the signal terminal 3 along the first direction X. The signal terminal 3 is inserted into the second channel 120, and the second limiting end 142 abuts against the signal terminal 3 to restrict the movement of the signal terminal 3 along the first direction X, thereby forming a positioning and restriction of the signal terminal 3 in the second channel 120. Moreover, the structural design of the second limiting end 142 abutting against the signal terminal 3 can prevent the signal terminal 3 from falling off or loosening, thereby ensuring the installation stability of the signal terminal 3 in the second channel 120. Moreover, the structural design of the second limiting end 142 being suspended within the second channel 120 can increase the overall elasticity of the second limiting part 140, thereby preventing the second limiting end 142 from damaging the signal terminal 3 while it abuts against the signal terminal 3, thus ensuring the service life and stability of the signal terminal 3.

[0050] In some embodiments, refer to Figure 4 , Figure 9 as well as Figure 10 The second limiting part 140 is provided on the first surface 101 of the main body 10. The second limiting part 140 has a protruding insertion part 143 on the side opposite to the second surface 102 along the third direction Z. (Refer to...) Figure 4 and Figure 14 An insertion hole 211 is provided on the body 21 located between two adjacent second locking portions 23 along the second direction Y, as shown in the figure. Figure 4 The main body 21 covers the first surface 101, and the plug-in part 143 is inserted into the socket 211. The design of the plug-in part 143 and the socket 211 is such that the main body 21 covers the first surface 101, the first locking part 22 is inserted into the first channel 110, the second locking part 23 is inserted into the second channel 120, and the plug-in part 143 on the second limiting part 140 can be inserted into the socket 211, thereby forming a plug-in connection between the second limiting part 140 and the main body 21. This ensures the installation stability between the main body 21 and the second limiting part 140, thereby ensuring the locking stability of the second locking part 23 on the signal terminal 3, and ensuring the stability of the second limiting end 142 in restricting the movement of the signal terminal 3 along the first direction X.

[0051] In some embodiments, refer to Figure 3The second locking part 23 can abut against the signal terminal 3 to restrict the movement of the signal terminal 3 along the first direction X. The structural design of the second locking part 23 restricting the movement of the signal terminal 3 along the first direction X, combined with the structural design of two adjacent second locking parts 23 clamping and locking the signal terminal 3, can ensure the locking effect of the signal terminal 3, ensure the installation stability of the signal terminal 3 in the second channel 120, and the structural design of the second locking part 23 abutting against the signal terminal 3 can prevent the signal terminal 3 from falling off or loosening, thereby ensuring the installation stability of the signal terminal 3 in the second channel 120.

[0052] In some embodiments, refer to Figure 9 and Figure 10 There are two second limiting parts 140, which are spaced apart along the second direction Y. One second limiting part 140 corresponds to one signal terminal 3. The end of the second limiting end 142 away from the second connecting end 141 is bent along the third direction Z to form a second bending part 1421. The second limiting end 142 abuts against the signal terminal 3 through the second bending part 1421 to restrict the movement of the signal terminal 3 along the first direction X.

[0053] In some embodiments, refer to Figure 13 and Figure 14 There are three second locking parts 23, which are spaced apart along the second direction Y. Two adjacent second locking parts 23 cooperate to clamp the signal terminal 3 to lock the signal terminal 3.

[0054] In some embodiments, refer to Figures 1-5 The main body 10 includes a first part 11 and a second part 12 that are spaced apart and connected to each other along the second direction Y. A first channel 110 is opened in the first part 11, and a second channel 120 is opened in the second part 12. (Refer to...) Figure 1 and Figure 3 The second part 12 includes a first sidewall 121 and a second sidewall 122 disposed opposite to each other along the second direction Y, as shown in the figure. Figure 1 , Figures 3-4 as well as Figure 9 , Figure 11 The first sidewall 121 has a first snap-fit ​​hole 1211 that communicates with the second channel 120, as shown in the figure. Figure 1 and Figure 3 A second snap-fit ​​hole 1221 communicating with the second channel 120 is provided on the second side wall 122. (Refer to...) Figure 3 , Figure 13 and Figure 14A first protrusion 231 protrudes from the second locking portion 23 adjacent to the first sidewall 121 along the second direction Y, and the first protrusion 231 is inserted into the first snap-fit ​​hole 1211. A second protrusion 232 protrudes from the second locking portion 23 adjacent to the second sidewall 122 along the second direction Y, and the second protrusion 232 is inserted into the second snap-fit ​​hole 1221. The snap-fit ​​connection between the first protrusion 231 and the first snap-fit ​​hole 1211, and the snap-fit ​​connection between the second protrusion 232 and the second snap-fit ​​hole 1221, can improve the assembly stability between the second locking portion 23 and the main body 10, thereby ensuring the clamping stability of the second locking portion 23 on the signal terminal 3 and the stability of restricting the movement of the signal terminal 3 along the first direction X, ensuring the installation stability of the signal terminal 3 in the second channel 120, and ensuring the stability of signal transmission.

[0055] In some embodiments, refer to Figure 1 , Figures 4-5 , Figure 11 as well as Figures 13-14 The main body 21 has connecting portions 212 at opposite ends along the second direction Y. The main body 21 covers the first surface 101. One connecting portion 212 is snapped into the third surface 103, and the other connecting portion 212 is snapped into the fourth surface 104. The snap-fit ​​connection between the connecting portion 212 and the main body 10 further ensures the assembly stability between the locking member 20 and the main body 10.

[0056] In some embodiments, refer to Figure 1 , Figures 4-5 , Figure 7 , Figure 9 , Figure 11 Two first protrusions 14 are provided on the third surface 103. The connecting part 212 on the third surface 103 is embedded between the two first protrusions 14, thereby ensuring the assembly stability between the connecting part 212 and the third surface 103. Two second protrusions 15 are provided on the fourth surface 104. The connecting part 212 on the fourth surface 104 is embedded between the two second protrusions 15, thereby ensuring the assembly stability between the connecting part 212 and the fourth surface 104.

Figure 13 and Figure 14 A protrusion 213 is provided on the connecting part 212 on the third surface 103. The protrusion 213 is embedded in the slot 13, so that the connecting part 212 is connected to the third surface 103 through the protrusion 213, ensuring the assembly stability between the connecting part 212 and the third surface 103.
