[0033] Type-C is a type of USB interface that can be inserted in either direction and supports USB standard functions such as charging, data transfer, and display output, just like other interfaces. Currently, mobile phones and cars are becoming increasingly indispensable in people's lives. Type-C offers more data port options, with 6-pin, 12-pin, 16-pin, 14-pin, and 24-pin being the most common. Type-C is a 3C product type, more convenient for general 3C applications, especially as it has become a standardized data transfer interface for mobile phones. With the increasing popularity of Type-C and improvements in manufacturing processes, it has laid the foundation for its use in automotive data transmission. However, the application of Type-C in the automotive field carries the risk of signal instability. Vibrations during vehicle operation, especially in extreme road conditions, can loosen or even detach the Type-C cable, leading to unstable signal transmission or even signal loss.
[0034] Therefore, such as Figures 1 to 5 The diagram shows the vehicle-mounted connector locking structure proposed in this utility model. The structure includes a first connector 200 and a second connector 100. The outer wall of the first connector 200 has a groove 210, and limiting portions 211 are connected to the opposite side walls of the groove 210. The limiting portions 211 extend along a direction perpendicular to the length of the first connector 200. The outer wall of the second connector 100 is provided with a floating elastic buckle 110. The elastic buckle 110 has a receiving groove 114 located in the middle of the elastic buckle 110. The first connector 200 and the second connector 100 are inserted into each other. The elastic buckle 110 is slidably inserted into the slot 210. The limiting part 211 is placed in the receiving slot 114 and abuts against the slot wall of the receiving slot 114 to prevent the elastic buckle 110 from coming out, thereby locking the first connector 200 and the second connector 100. This enhances the connection stability between the first connector 200 and the second connector 100, reduces the risk of loosening or falling off the connection, and ensures the continuity of data transmission and the stability of the charging function.
[0035] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 The elastic buckle 110 includes a fastening part 111, a connecting part 112, and a pressing part 113. One end of the fastening part 111 away from the pressing part 113 is fixed to the second connecting member 100. There is a certain space between the elastic buckle 110 and the second connecting member 100, so that the elastic buckle 110 can move towards the second connecting member 100 with one end as the fulcrum. The fastening part 111 is inserted into the slot 210. The connecting part 112 connects the pressing part 113 and the fastening part 111. The connecting part 112, the fastening part 111, and the pressing part 113 enclose and form a receiving groove 114. The pressing part 113 can be forced and drive the receiving groove 114 to move towards the center line of the second connecting member 100, so as to drive the receiving groove 114 to disengage from the limiting part 211. The pressing part 113 has a rectangular structure and a protrusion. When the user presses the pressing part 113, the protrusion increases the force-bearing point, thus facilitating the insertion and removal of the second connector 100 and the first connector 200, and making force application easier. After the receiving groove 114 disengages from the limiting part 211, the first connector 200 and the second connector 100 are unlocked, thereby achieving quick disassembly. The pressing part 113, the connecting part 112, and the fastening part 111 work together to make the first connector 200 and the second connector 100 easy to insert, reliable to connect, and easy to disassemble, effectively improving assembly efficiency and ease of use.
[0036] In some embodiments of this utility model, reference is made to Figures 1 to 3 The fastening part 111 is provided with an inclined guide surface, which is inclined towards the first connector 200. During assembly, it can form a guiding engagement with the slot 210 of the first connector 200, allowing the elastic buckle 110 to slide into the slot 210 quickly and smoothly, reducing insertion resistance and alignment time. The outer end face of the slot 210 is provided with an inclined surface, which corresponds to the inclined guide surface, making the connection between the first connector 200 and the second connector 100 natural and aesthetically pleasing.
[0037] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4The second connector 100 is provided with two first stops 120, which are located on both sides of the elastic buckle 110. The height of the first stops 120 is greater than or equal to the height of the elastic buckle 110. The two first stops 120 form effective protection on both sides of the elastic buckle 110, which can effectively prevent the second connector 100 from being accidentally touched or squeezed during use and thus accidentally released from locking. Second stops 1121 are provided on both sides of the elastic buckle 110, extending along a direction perpendicular to the length of the elastic buckle 110. The first stops 120 correspond to the second stops 1121 to restrict the elastic buckle 110 from disengaging from the first stops 120, further enhancing the stability and reliability of the connection structure, while not affecting the normal pressing and disassembly operation of the elastic buckle 110. It should be noted that the accommodating groove 114 forms an accommodating space between the side wall of the accommodating groove 114 facing the first connector 200 and the side end face of the first stop block 120 facing the first connector 200. After the first connector 200 and the second connector 100 are inserted, the limiting part 211 is placed in the accommodating space, thereby restricting the movement of the limiting part 211 and enhancing the connection stability between the first connector 200 and the second connector 100.
[0038] In some embodiments of this utility model, reference is made to Figure 3 The inner wall of the first connector 200 is provided with two first sliding grooves 220, and the outer peripheral wall of the second connector 100 is provided with two first guide strips 130 along its length. One end of the first guide strip 130 is connected to the end face of the first stop 120 facing the first connector 200. The two first guide strips 130 are spaced apart along the diagonal of the second connector 100. The diagonally distributed guide strips can provide constraint from two directions, effectively preventing relative offset and torsion of the first connector 200 and the second connector 100, and enhancing the stability of the overall connection. The first guide strips 130 correspond one-to-one with the first sliding grooves 220. The cooperation between the first guide strips 130 and the first sliding grooves 220 provides precise guidance for the insertion of the first connector 200 and the second connector 100 during assembly, improving assembly efficiency.
[0039] In some embodiments of this utility model, reference is made to Figure 2 and Figure 5 The outer wall of the second connector 100 is provided with a second sliding groove 140 along its length. The second sliding groove 140 is located on the end face of the second connector 100 opposite to the elastic buckle 110. The inner wall of the first connector 200 is provided with a second guide strip 230, which is slidably inserted into the second sliding groove 140. The sliding engagement of the second guide strip 230 and the second sliding groove 140 can further improve the stability of the connection and also provide guidance for the insertion of the first connector 200 and the second connector 100 during assembly, thereby improving assembly efficiency.
[0040] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 The second connector 100 includes a first transmission connector 150, a first protective cover 160, and a cable protector 170. The first transmission connector 150 is embedded in the inner wall of the first protective cover 160. An elastic buckle 110 is disposed on the first protective cover 160. A wire is connected to the first protective cover 160. The cable protector 170 is disposed at the connection point between the wire and the first protective cover 160, and can wrap around the connection point, providing support and stress relief, reducing loosening of the interface due to wire shaking or pulling, and ensuring the reliability of the connection. This ensures the normal transmission of network signals. The first transmission connector 150 is used for signal transmission.
[0041] Furthermore, in some embodiments of this utility model, the first protective cover 160 is made of polybutylene terephthalate (PET), a thermoplastic polyester with high mechanical strength, excellent heat resistance, chemical corrosion resistance, electrical insulation, and processing performance. The PET component is reinforced with 20% glass fiber by weight, giving the first protective cover 160 a UL 94V-0 flame retardant rating. The cable protector 170 is made of polyvinyl chloride (PVC), which has excellent electrical insulation properties, effectively preventing short circuits between the core wires inside the cable. It also avoids interference from external electric fields on the network signal, ensuring the stability and accuracy of network signal transmission.
[0042] It should be noted that electrical wires can be made in various specifications, such as 4-core, 6-core, 12-core, and 16-core. There are no specific restrictions on the specifications used; flexibility is allowed depending on the application scenario to adapt to diverse needs.
[0043] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 It is understandable that the elastic buckle 110 and the first protective cover 160 are integrally molded. This integral molding structure avoids problems such as gaps and loosening that may occur when the elastic buckle 110 and the first protective cover 160 are connected by splicing or assembly, making the entire structure more stable. The connection strength between the elastic buckle 110 and the first protective cover 160 is higher, and it can better withstand the action of external forces.
[0044] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2The first connector 200 includes a second transmission connector 240 and a second protective cover 250. A slot 210 is disposed in the second protective cover 250. One end of the second transmission connector 240 is embedded in the inner wall of the second protective cover 250. The second transmission connector 240 is used for signal transmission. It is understood that a fixing member 260 is sleeved around the second transmission connector 240. One end of the second transmission connector 240 is embedded in the second protective cover 250, and the other end of the second transmission connector 240 is sleeved around the fixing member 260. The fixing member 260 can protect the internal metal circuits and electronic components of the second transmission connector 240, and can also firmly fix the second transmission connector 240 in the second protective cover 250, preventing the connection between the second transmission connector 240 and the second protective cover 250 from loosening due to insertion and removal operations, enhancing connection stability, and ensuring the stability of signal transmission. It should be noted that the second protective cover 250 has multiple insertion protrusions 251 on the side facing the second transmission connector 240, and the fixing member 260 has multiple insertion slots 261 on the side facing the second protective cover 250. The second protective cover 250 and the fixing member 260 are inserted and fixed.
[0045] In some embodiments of this utility model, the first connector 200 is a Type-C female connector, and the second connector 100 is a Type-C male connector. The structural design of the elastic buckle 110 and the slot 210 effectively ensures the stability and reliability of the connector during the connection process, while also facilitating users to quickly and accurately complete the insertion and removal operations, thus improving the user experience.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
