[0019] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] By providing a snap - type high - speed FPC connector in an embodiment of the present application, a plurality of technical problems in the prior art, such as the plastic cover of the FPC connector rotating with the metal ground piece and easy wear of the plastic, are solved. It should be noted that in the present application, the direction in which the rotating cover body is located relative to the insulating body is up, above, upper side, upper end, top, top end or top surface, and the opposite direction is down, below, lower side, lower end, bottom, bottom end or bottom surface.

[0021] As Figures 1 to 6 shown, an embodiment of the present application: a snap - type high - speed FPC connector, comprising: a rotating cover body 30, a locking part 40, an insulating body 10, and terminals 20. The rotating cover body 30 is installed above the insulating body 10, and a plug - in cavity 104 for plugging in the FPC board 50 is formed between its front end and the insulating body 10. A plurality of mounting holes 101 are evenly spaced at the rear end of the insulating body 10, and the terminals 20 are plugged into the mounting holes 101. The locking part 40 is inserted on both sides of the insulating body 10. Among them, a shielding sheet 31 is provided inside the rotating cover body 30. Referring to Figure 3 , the shielding sheet 31 includes a pair of protruding parts 320, and the protruding parts 320 extend out of both ends of the rotating cover body 30 along the length direction and abut against the locking part 40.

[0022] The shielding sheet 31 is buckled with the locking part 40, which can enhance the contact stability of the terminals 20, extend the service life of the rotating cover body 30, and the product is suitable for vehicle - mounted and other harsh environments, with a wider application scenario and scope.

[0023] As Figure 6 shown, the locking part 40 includes a grounding part 41 and an elastic locking part 42 formed integrally. The grounding part 41 includes a short plate 411 and a long plate 410 connected in a U - shape. The elastic locking part 42 includes a clamping part 420 and an abutting concave part 421 connected to the short plate 411. The protruding part of the shielding sheet 31 is snapped into the abutting concave part 421. The grounding part 41 further includes a bottom plate 412, and the bottom plate 412 is horizontally bent from the lower end surface of the long plate 410 and extends towards the short plate 411. The setting of the bottom plate 412 can achieve the grounding function.

[0024] Referring to Figure 2, on the left and right end walls of the insulating body 10, there are respectively provided a lower end groove 103 and an upper end groove 102 for inserting the grounding part 41 and the elastic locking part 42. The grounding part 41 is inserted into the lower end groove 103, and the clamping part 420 is inserted into the upper end groove 102.

[0025] Further, the lower end groove 103 includes a first notch 1030 and a second notch 1031. Figure 4 And Figure 5 The figure shows a schematic diagram after the locking part 40 is inserted into the upper end groove 102 and the lower end groove 103. Among them, the second notch 1031 penetrates through the insulating body 10 in the width direction. The short plate 411 extends into the first notch 1030, and the long plate 410 extends into the second notch 1031. By setting multiple grooves to correspond to the clamping of the locking part 40, the dual functions of elastic clamping and grounding of the locking part 40 can be realized.

[0026] The shielding sheet 31 further includes an arched support groove 330 extending towards the rear end of the insulating body 10. When the rotary cover 30 is in the opened state, the semi-circular bend of the arched support groove 330 rides on the upper end surface of the long plate 410 of the locking part 40. Since the shielding sheet 31 is made of metal material and the locking part 40 is also made of metal material, a rotary support is formed by the contact between the shielding sheet 31 and the locking part 40, which can reduce the wear on the rotary cover 30 and the insulating body 10 when opening or closing the cover, and extend the service life of the connector.

[0027] Refer to Figure 1 Or Figure 2 , the shielding sheet 31 further includes a holding part 310, and the holding part 310 extends out of the edge of the long side 410 of the rotary cover 30. Adding the holding part 310 can facilitate the flipping of the cover, and the operation is simple and fast.

[0028] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0029] The above-described embodiments only express the implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
