[0023] FAKRA connectors are widely used in automobiles, typically in GPS positioning systems, remote control systems, in-car phone systems, satellite radios, and in-car internet access. FAKRA connectors utilize a male-female pairing design. The female connector is typically integrated into the motherboard or interface module of an in-vehicle electronic device, while the male connector extends through a cable to the corresponding signal source or receiver. A snap-fit ​​mechanism provides mechanical locking and electrical continuity between the two.

[0024] However, during driving, high-frequency vibrations caused by bumpy roads, shocks from sudden acceleration and braking, and vibrations from engine operation can all compromise connector stability, causing the connector to loosen or even accidentally separate. A loose or separated connector not only leads to unstable connections but also compromises signal transmission quality, making it difficult to meet the growing demand for stable connections and efficient transmission in automotive electronic systems.

[0025] For this reason, Figures 1 to 7The figure shows the connector interlocking structure proposed by the present invention, which includes a first connector 100, a second connector 200, and a snap-fit ​​member 300. The first connector 100 is provided with an elastic member 110, and one end of the elastic member 110 is provided with a connecting groove 111. The second connector 200 is provided with a connecting protrusion 210 on the side facing the first connector 100. The connecting protrusion 210 is provided with an inclined surface on the side facing the first connector 100. The first connector 100 and the second connector 200 are plugged together, and the connecting protrusion 210 slides and engages with the connecting groove 111. The inclined surface can gradually guide the connecting protrusion 210 to slide and engage with the connecting groove 111. The clamping member 300 has a first position and a second position. In the first position, the clamping member 300 is clamped to the first connector 100. In the second position, the second connector 200 is plugged into the first connector 100. The clamping member 300 is clamped to the connection between the first connector 100 and the second connector 200. The clamping member 300 is used to prevent the connecting protrusion 210 from falling out of the connecting groove 111. After the first connector 100 and the second connector 200 are plugged into each other, the clamping member 300 can be moved from the first position to the second position, clamped to the connection between the first connector 100 and the second connector 200. The clamping member 300 can prevent the connecting groove 111 from falling out of the connecting protrusion 210, thereby locking the first connector 100 and the second connector 200 to prevent loosening, strengthen the connection stability between the first connector 100 and the second connector 200, and ensure the quality of signal transmission.

[0026] It should be noted that the first connector 100 may be a female connector, and the second connector 200 may be a male connector. Alternatively, the first connector 100 may be a male connector, and the second connector may be a female connector. In the present invention, preferably, the first connector 100 is a female connector, and the second connector 200 is a male connector.

[0027] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the elastic member 110 includes a main body 113 and a connecting portion 112. The connecting portion 112 is connected to the middle portion of the main body 113. The elastic member 110 is fixed to the first connector 100 via the connecting portion 112, forming a seesaw structure. The first connector 100, the connecting portion 112, and the main body 113 together enclose a snap-fit ​​groove 120. The opening of the snap-fit ​​groove 120 faces the side away from the connecting groove 111, and the distance between the two side walls of the snap-fit ​​groove 120 gradually increases along the side away from the connecting groove 111. A limiting portion 310 is provided inside the snap-fit ​​member 300. The limiting portion 310 is arranged along a direction perpendicular to the length of the snap-fit ​​member 300. When the snap-fit ​​member 300 is in the second position, the limiting portion 310 is engaged with the snap-fit ​​groove 120 to limit the movement of the snap-fit ​​member 300 in the direction toward the second connector 200.

[0028] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, it can be understood that pressing the end of the elastic member 110 away from the connection groove 111 can cause the connection protrusion 210 to disengage from the connection groove 111, quickly completing the unlocking of the first connector 100 and the second connector 200. A protective shell 360 is provided at one end of the clamping member 300. The thickness of the protective shell 360 is greater than the distance between the elastic member 110 and the first connector 100. When the clamping member 300 is in the second position, the protective shell 360 is sleeved on the end of the elastic member 110 away from the connection groove 111, which can effectively prevent the side of the elastic member 110 away from the connection groove 111 from being subjected to force, thereby preventing the connection protrusion 210 from disengaging from the connection groove 111, thereby preventing the first connector 100 and the second connector 200 from loosening or detaching, and ensuring the stability of signal transmission. It is understandable that the outer wall of the protective shell 360 is also provided with anti-slip strips. When the clamping part 300 is moved, the anti-slip strips can significantly increase the friction between the operator's hand and the protective shell 360, thereby facilitating the radial movement of the clamping part 300.

[0029] In some embodiments of the present invention, Figure 4 and Figure 7 As shown, a hook 320 is provided on the end of the clamping member 300 facing the second connector 200, and a buckle portion 130 is provided on the side of the first connector 100 facing the elastic member 110. The hook 320 is arranged in a floating manner. When the clamping member 300 is assembled with the first connector 100, the buckle can be inserted into the first connector 100 from the side of the first connector 100 facing away from the connection groove 111. The hook 320 can slide along the outer wall of the first connector 100 until it snaps into the buckle portion 130, thereby completing the clamping and fixing of the clamping member 300 to the first connector 100. A limit block is also provided on the end of the clamping member 300 facing the second connector 200. The limit block is arranged at the top of the clamping member 300 and can limit the movement of the hook 320 in the direction toward the top of the clamping member 300, thereby preventing the hook 320 from deforming. When the snap-fitting member 300 is in the first position, the snap-fitting portion 130 engages with the hook 320, which can limit the snap-fitting member 300 from moving along the length direction of the first connecting member 100, thereby fixing the snap-fitting member 300 on the first connecting member 100, and preventing the snap-fitting member 300 from being lost during use of the first connecting member 100.

[0030] In some embodiments of the present invention, Figure 4 、 Figure 6 and Figure 7As shown, a protrusion 220 is provided on the side of the second connector 200 facing the first connector 100. The protrusion 220 has a trapezoidal structure and is located on the same side of the second connector 200 as the connecting protrusion 210. The height of the protrusion 220 is less than that of the connecting protrusion 210. A first inclined surface 321 is provided on the end of the hook 320 facing the second connector 200, and a second inclined surface 221 is provided on the protrusion 220. The first inclined surface 321 cooperates with the second inclined surface 221 to guide the hook 320 out of the engaging portion 130. The first connector 100 is plugged into the second connector 200, and the first bevel 321 contacts the second bevel 221. During the plugging process, the first bevel 321 slides along the second bevel 221, driving the ejection portion 220 to eject the hook 320 from the fastening portion 130. The fastening member 300 is released from the first connector 100 and can be forced to move toward the second connector 200 to the second position. The cooperation between the first bevel 321 and the second bevel 221 provides a simple structure, allowing the hook 320 to be quickly released without complex operations, thereby improving overall assembly efficiency.

[0031] In some embodiments of the present invention, Figure 4 、 Figure 6 and Figure 7 As shown, the connector 300 is hollow and has two hooks 320, symmetrically arranged on either side of the connector 300. It also has two snap-fitting portions 130 and two ejection portions 220, spaced apart on either side of the connecting protrusion 210. The ejection portions 220 correspond one-to-one with the hooks 320, and the snap-fitting portions 130 correspond one-to-one with the hooks 320. The two hooks 320 and the two snap-fitting portions 130 enhance the connection stability between the connector 300 and the first connector 100, preventing the connector 300 from accidentally falling off or being lost during frequent plugging and unplugging or during vibration.

[0032] In some embodiments of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the first connector 100 is provided with a first latching slot 140 and a second latching slot 150. The first latching slot 140 and the second latching slot 150 are of equal size and are spaced apart along the length of the first connector 100. A latching portion 330 is provided on the outer wall of the clip 300. When the clip 300 is in the first position, the latching portion 330 is latched in the first latching slot 140. When the clip 300 is in the second position, the latching portion 330 is latched in the second latching slot 150. The thickness of the latching portion 330 is smaller than that of the first latching slot 140 and the second latching slot 150. This allows the latching portion 330 to slide out of the first latching slot 140 when the hook 320 is released from the fastening portion 130, thereby moving the clip 300 from the first position to the second position.

[0033] Furthermore, in some embodiments of the present invention, two clamping portions 330 are provided, and the two clamping portions 330 are symmetrically arranged along the center line of the clamping member 300, and the two clamping portions 330 are respectively provided on opposite sides of the clamping member 300. There are also two first clamping slots 140 and two second clamping slots 150. The double-sided clamping structure can balance the force distribution of the clamping member 300 during assembly, avoid deflection or jamming caused by unilateral force, and improve the stability of the connection.

[0034] In some embodiments of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the first connector 100 is provided with a first chute 160. The first engaging groove 140 and the second engaging groove 150 are provided in the groove wall of the first chute 160. The first chute 160 is located near the side of the first connector 100 facing away from the second connector 200. The first chute 160 extends along the length of the first connector 100. A first slider 340 is provided on the side wall of the elastic member 110. The engaging portion 330 is provided in the first slider 340. The first slider 340 can perform linear reciprocating motion within the first chute 160. The first chute 160 and the first slider 340 cooperate to guide the movement of the connecting member 300, guiding the connecting member 300 from the first position to the second position. The first slider 340 is provided in the first chute 160 to prevent the connecting member 300 from separating from the first connector 100, thereby improving the stability of the connection between the connecting member 300 and the first connector 100.

[0035] In some embodiments of the present invention, Figure 3 、 Figure 5 and Figure 7 As shown, the first connector 100 is provided with a second chute 170, which is disposed on a side of the first connector 100 near the second connector 200. The second chute 170 and the first chute 160 are spaced apart in the thickness direction of the first connector 100. The clip 300 is provided with a second slider 350, which is slidably disposed in the second chute 170. The dual guiding constraint formed by the first chute 160 and the second chute 170 limits the movement of the clip 300 along the length of the first connector 100, thereby ensuring the position accuracy of the clip 300 when switching between the first and second positions, making assembly of the clip 300 more convenient.

[0036] In some embodiments of the present invention, Figure 3 and Figure 6As shown, the interior of the first connector 100 is provided with a plurality of guide grooves 180, each having a rectangular cross-section. The outer wall of the second connector 200 is provided with a plurality of guide protrusions 230, which slide and plug into the guide grooves 180. The guide protrusions 230 cooperate with the guide grooves 180 to guide the insertion of the first connector 100 and the second connector 200, ensuring that the first connector 100 and the second connector 200 are connected in the correct direction. The guide grooves 180 are arranged circumferentially and spaced apart along the inner wall of the first connector 100, which can effectively improve the torsional resistance of the connection between the first connector 100 and the second connector 200, reduce wear, and extend the service life.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
