Meanwhile, the mating connector 2 is provided with a clip groove 3. With this, when the connection cable 1 is inserted into the mating connector 2, the protrusion 13 engages with the clip groove 3, thereby coupling the connection cable 1 to the mating connector.

[0024] 3 to 5, there are shown perspective exploded schematic views from both sides and combined cross-sectional views of a connection cable with a snap-fit ​​type protective cover of the present invention. The connection cable with a snap-fit ​​type protective cover 1 of the present invention comprises an insulating washer 10, a circuit board 20, a protective cover 30, and a spring 40. The insulating washer 10 includes a main body 11. The main body 11 is formed with an insertion groove 110 and a conductive opening 111. The conductive opening 111 communicates with the insertion groove 110 and is located at the bottom of the main body 11. The main body 11 further includes an elastic arm 12 and a protrusion 13 disposed on the elastic arm 12.

[0025] The circuit board 20 includes a substrate 21 and a plurality of conductive parts 22 arranged on the substrate 21. The substrate 21 is inserted into the insertion groove 110. The conductive parts 22 are exposed from the conductive openings 111. In this embodiment, the substrate 21 is a flexible substrate, and each conductive part 22 is provided as a golden finger, but is not limited thereto.

[0026] Furthermore, the protective cover 30 is slidably coupled to the body 11 and covers the conductive opening 111. One end of the spring 40 abuts against the body 11 and the other end is fixed to the protective cover 30.

[0027] In this embodiment, two rows of conductive parts 22 are arranged at an interval on the substrate 21. When the protective cover 30 covers the conductive opening 111, most of the conductive parts 22 are shielded, and only the ends of the conductive parts 22 are exposed.

[0028] Specifically, the protective cover 30 includes a shielding plate 31 and two frame arms 32 connected to the shielding plate 31. Each frame arm 32 curves and extends from one side of the shielding plate 31 to form a fitting space 320. Both sides of the body 11 are respectively inserted into the fitting space 320. The protective cover 30 can be made of metal or plastic according to the needs of use.

[0029] Each of the frame arms 32 includes a side plate 321 connected to the shielding plate 31, and a top plate 322 extending in a curved manner from the side plate 321. A hook portion 323 is provided at one end of the side plate 321. The hook portion 323 is engaged with the main body 11.

The spring 40 is inserted into the insertion groove 325. Furthermore, each of the frame arms 32 has a blocking portion 326 curvingly extending from the top plate 322 in a direction away from the insertion groove 325. The blocking portion 326 abuts against the outer surface of the main body 11.

[0031] Furthermore, the main body 11 has a stopper portion 112. The stopper portion 112 and the spring 40 are inserted into the insertion groove 325. The protective cover 30 has a spring insertion pin 33. One end of the spring 40 abuts against the stopper portion 112, and the other end is fitted onto the spring insertion pin 33 (see FIG. 5). In this embodiment, the spring insertion pin 33 curves and extends from one end of the top plate 322 into the insertion groove 325.

[0032] In one embodiment of the present invention, the connection cable 1 includes a plurality of support plates 50 and one auxiliary plate 60. These support plates 50 are disposed on both sides of the shielding plate 31, respectively, and are used to reinforce the structure of the shielding plate 31. The auxiliary plate 60 is disposed at the front end that is inserted into the insertion groove 110 of the board 21, and is used to reinforce the structure of the board 21 (see FIG. 6).

[0033] 6 to 8, there are shown schematic diagrams of a connection between a connection cable having a snap-fit ​​protective cover of the present invention and a mating connector, and cross-sectional views from both sides after connection.

When the connection cable 1 is inserted and connected to the mating connector 2, the elastic arm 12 is pressed and moved toward the main body 11, and the protrusion 13 engages with the clip groove 3 to be coupled to the mating connector 2 (see Fig. 1).

[0034] 7 and 8, when the body 11 of the connection cable 1 is inserted into the mating connector 2, the protective cover 30 is pressed against the mating connector 2 to compress the spring 40 and expose the conductive opening 111. At this time, the conductive part 22 located in the conductive opening 111 and the terminal 4 of the mating connector 2 are conductive with each other to achieve the purpose of electronic, electrical or data connection.

[0035] Moreover, when the main body 11 of the connection cable 1 is pulled out of the mating connector 2, the protective cover 30 returns to its initial position due to the elastic restoring force of the spring, and again shields the conductive portion 22 on the board 21.

[0036] The protective cover 30 is mainly used to cover the main body 11 and to protect the conductive portion 22 of the circuit board 20. The protective cover 30 has a function of protecting the conductive portion 22 of the circuit board 20 when the connection cable 1 is not inserted and connected, and also of continuing to protect the conductive portion 22 during the process of the connection cable 1 mating with the mating connector 2. Furthermore, by providing the spring 40, the connection cable 1 can return the protective cover 30 to its initial position when it is pulled out of the mating connector 2.
