[0029] A Type-C cable with a self-locking device, see reference Figure 1-5The device includes a main body 200 and a transmission cable 100 that cooperates with it. The transmission cable 100 includes a plug 110, a cable body 140, and a mounting base 120 disposed between the two. The mounting base 120 extends backward toward the end face edge of the plug 110 to form a locking member 130. The main body 200 is provided with a slot 210 for partial insertion of the mounting base 120 and the locking member 130. The locking member 130 includes a locking protrusion 131 and a pressing part 132 arranged sequentially from front to back. When the locking member 130 is inserted into the slot 210, the locking protrusion 131 engages with the slot 210 to realize the connection between the transmission cable 100 and the device. The locking operation on the main body 200 features a right-angled triangular cross-section for the locking protrusion 131. The inclined surface of the locking protrusion 131 serves as a guide surface, and the vertical surface serves as a contact surface. During actual assembly, simply align one end of the transmission cable 100 with the slot 210 of the main body and insert it. During insertion, the inclined surface of the locking protrusion 131 acts as a guide surface, facilitating the smooth sliding of the locking protrusion 131 into the slot 210. The vertical surface acts as a contact surface, contacting the internal structure of the slot 210. This enables automatic locking during assembly, effectively resisting accidental pulling or shaking of the cable and greatly reducing the risk of detachment.

[0030] It should be noted that in this embodiment, the transmission cable 100 is a Type-C cable and the device body 200 is a keyboard. In other embodiments, the device body 200 can also be other devices, such as speakers, to meet the requirements of use in different products, and no limitation is made here.

[0031] In this embodiment, please refer to Figure 2 and Figure 4 As shown, the protrusion 131 is made of an elastic material, and the slot 210 is generally convex in shape. The outer edge of the bottom of the slot 210 protrudes upward to form a protruding edge 211 that engages with the abutment surface. This design allows the protrusion 131 to deform along the protruding edge 211 when the locking member 130 is inserted into the slot 210, until the protrusion 131 is completely engaged in the slot 210. After engagement, the protruding edge 211 abuts against the vertical surface of the protrusion 131, thus achieving automatic locking. The protrusion 131 is preferably made of plastic. Of course, in other embodiments, the protrusion 131 can also be made of other elastic materials, which is not limited here.

[0032] In this embodiment, please refer to Figure 3As shown, the locking member 130 also includes a connecting plate 133. The latching protrusion 131 and the pressing part 132 are both disposed on the connecting plate 133. The front end face of the connecting plate 133 is provided with a guide slope 134. The connecting plate 133 is provided with strip grooves spaced apart along its length. The guide slope 134 provided on the connecting plate 133 can assist the locking member 130 in being guided into the latching slot 210. Furthermore, the design of the strip grooves greatly increases the flexibility of the connecting plate 133, making it easier and more uniform for the front latching protrusion 131 to deform when the pressing part 132 is pressed, thus improving the unlocking feel and reliability.

[0033] In this embodiment, please refer to Figure 3 and Figure 4 As shown, the mounting base 120 includes a narrow base portion 122 and a wide base portion 121 integrally formed from front to back. The size of the wide base portion 121 is larger than that of the narrow base portion 122. The size of the narrow base portion 122 is the same as that of the slot 210. When the narrow base portion 122 is inserted into the slot 210, the outer wall surface of the slot 210 abuts against the front end surface of the wide base portion 121. This structure serves to limit the insertion depth, ensuring that the protrusion 131 can accurately reach the position to engage with the protrusion 211. At the same time, it makes the mounting base 120 fit tightly against the main body 200 of the equipment, resulting in a neat appearance and improving the aesthetics of the product.

[0034] In this embodiment, please refer to Figure 3 and Figure 4 As shown, the end of the connecting plate 133 facing away from the plug 110 extends above the wide seat 121. The pressing part 132 is located at the end of the connecting plate 133 facing away from the plug 110. The pressing part 132 is provided with anti-slip texture. When the pressing part 132 is pressed towards the mounting base 120, the locking protrusion 131 can disengage from the locking groove 210 to achieve the unlocking operation. The above design makes the pressing part 132 located outside the main body 200 of the device after the two are assembled. The operation is ergonomic and very convenient to press with your fingers. Moreover, the anti-slip texture increases the coefficient of friction and prevents slipping during operation.

[0035] In this embodiment, please refer to Figure 2 and Figure 5 As shown, a guide ridge 230 protrudes downward along its thickness direction in the middle of the top wall of the slot 210, and a guide groove 123 that matches the guide ridge 230 is recessed on the narrow seat portion 122. This structure ensures that the transmission line can only be inserted into the device in the only correct direction, thus playing a foolproof role.

[0036] In this embodiment, please refer to Figure 4As shown, the slot 210 has a socket 220 on the main body 200 of the device that is compatible with the plug 110. When the mounting base 120 is positioned by the slot 210, the plug 110 at its front end can be accurately aligned and inserted into the socket 220, completing the electrical connection and physical locking operation in one go.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
