In case of conflict, embodiments of the present invention and various features of the embodiments may be combined with each other within the scope of the present invention and, for each embodiment, the same reference signs represent the same or similar features in different figures.

Referring to fig. 1 to 10, as an object of the present invention, an electrical connector 100 is provided, which is detachably fixed to a flat cable 200 and includes an insulating base 110, a pressure plate 130 and a pair of metal spring pieces 140, wherein a receiving space for receiving a conductive terminal 120 is provided in the insulating base 110, the flat cable 200 can be inserted into or pulled out of the receiving space, and two ends of the flat cable 200 are respectively provided with an opening 220. The platen 130 is rotatably coupled to the housing 110 to be rotatably separated from and engaged with the receiving space. In the embodiments of the present invention, the flat cable 200 is a flat cable without conflict. The metal elastic sheet 140 includes a fixing portion 141, a grounding portion 142, a conductive portion 143, a plugging portion 144, and a pressing portion 145 extending into the upper portion of the accommodating space, the fixing portion 141 is fixedly connected to one side end of the insulating base 110, the grounding portion 142 can be specifically set as a grounding pin, the grounding pin is welded to the circuit board and is electrically connected to the grounding end, the conductive portion 143 is disposed on the pressing portion 145, the pressing portion 145 extends toward the accommodating space, the pressing portion 145 presses the conductive portion 143 to be electrically connected to the grounding portion 210 of the shielding layer on the flat cable 200 under the pressing action of the pressing force generated when the pressing plate 130 is pressed, and the grounding portion 210 is grounded via the conductive portion 143 and the grounding portion 142. Also, the pressing portion 145 presses the insertion portion 144 to be inserted into the opening 220 to prevent the flat cable 200 from being displaced with respect to the accommodating space, that is, to prevent the flat cable 200 from being positionally shifted in the accommodating space or being pulled out from the accommodating space. Therefore, on one hand, the pressing part 145 of the metal elastic sheet 140 receives the acting force of the pressing plate 130 to apply a good positioning acting force to the conductive part 143 of the metal elastic sheet 140 to keep contact with the ground conducting part 210 of the flat cable 200, so that the contact between the two parts is very reliable and accurate, the contact stability is high, and the drying effect is good, so that external interference signals are grounded through the ground conducting part 210, the conductive part 143 and the ground conducting part 142 in sequence; on the other hand, the plugging part 144 of the metal elastic sheet 140 is plugged and matched with the end opening 220 of the flat cable 200, so that the flat cable 200 is prevented from being loosened, the transmission interruption of power supply or signals is avoided, and the normal operation of the electronic equipment is ensured.

Referring to fig. 2 to 5, specifically, the pressing portion 145 is a flat plate, the conductive portion 143 is a convex curved surface structure and is disposed at an end of the pressing portion 145 relatively far from the fixing portion 141, the convex curved surface structure may be a convex arc surface, a convex spherical surface, etc., in this embodiment, a convex spherical surface corresponding to a bottommost portion of a sphere is adopted, and the convex spherical surface abuts against the ground guiding portion 210 in a state that the rotating and pressing plate 130 is pressed against the accommodating space, and it can be known that a connecting portion of the flat cable 200 and the electrical connector 100 is a flat plate, so that the abutting portion of the ground guiding portion 210 and the conductive portion 143 is a flat surface, and therefore, the convex spherical surface of the ground guiding portion 210 abuts against the ground guiding portion 210 in a point contact manner, so that a stable point contact can be always maintained regardless of the inclination of the angle of the flat cable 200.

Referring to fig. 7, specifically, two ends of the side surface of the rotating pressing plate 130 facing the pressing portion 145 are provided with a pressing surface 131, and the pressing surface 131 at the same end applies a force to the pressing portion 145, especially to the peripheral surface around the conductive portion 143, that is, the two pressing surfaces 131 symmetrically apply a symmetrical force to the two peripheral surfaces. Therefore, since the pressing surface 131 applies a pressing force against the circumferential surface, the stability of the contact between the ground guide portion 210 and the ground guide portion 210 can be improved.

Referring to fig. 2 to 5, specifically, the fixing portion 141 is a vertical plate, the metal elastic sheet 140 further includes an elastic portion 146 and a supporting portion 147, the elastic portion 146 is connected to a top portion of the fixing portion 141, two ends of the supporting portion 147 are respectively connected to the elastic portion 146 and the pressing portion 145, so that, when the pressing portion 145 is pressed by the pressing plate 130, the supporting portion 147 transmits a pressing force and allows the elastic portion 146 to elastically deform around a top portion of the fixing portion 141, and further, the pressing portion 145 can displace towards the grounding portion 210 relative to the elastic portion 146 or/and the top portion of the fixing portion 141 to ensure that the conducting portion 143 always keeps contact with the grounding portion 210, and in the absence of the above elastic deformation and movement, the conducting portion 143 does not interfere with the flat cable 200, thereby preventing a scratch on the shielding layer during the insertion or extraction of the flat cable 200, and preventing adverse effects on the performance of the shielding layer, and the pressing portion 145 and the grounding portion 142 respectively extend away from the fixing portion 141 and the lower portion 142. In this way, since the grounding portion 142 is generally soldered on a circuit board, the pressing portion 145 and the grounding portion 142 form moments in opposite directions with respect to the fixing portion 141, so that stability and reliability of the elastic deformation of the pressing portion 145 of the metal dome 140 are improved.

Preferably, the metal elastic sheet 140 further includes a first bending portion 148 having a first guiding surface 1481 and a second bending portion 149 having a second guiding surface 1491, the first bending portion is connected to the supporting portion 147 and located on a side away from the pressing portion 145, that is, in the insertion direction, the pressing portion 145 is located downstream of the first bending portion, the second bending portion 149 is connected to the pressing portion 145, and the first guiding surface 1481 and the second guiding surface 1491 both extend toward a direction away from the fixing portion 141 and guide the insertion of the flat cable 200 into the accommodating space along the insertion direction, so that the first guiding surface 1481 and the second guiding surface 1491 can ensure one-time aligned insertion under the condition of guiding and limiting the insertion of the flat cable 200 into the accommodating space, thereby facilitating accurate positioning of the insertion position of the insertion portion 144 and the opening 220, the first guiding surface 1491 located upstream of the second guiding surface 1491 leads the second guiding surface 1491 to guide the insertion of the flat cable 200, and can bear a larger impact force from the flat cable 200 initially inserted into the flat cable, thereby improving reliability of the flat cable, the insertion of the flat cable 200, the first guiding surface and the included angle of the first guiding surface and the second guiding surface 1491 are larger than the second guiding surface 1481, and the second guiding surface 1481 and the second guiding surface and the included angle can provide a larger acute angle.

Referring to fig. 2 and 4, specifically, the metal elastic sheet 140 further includes an inclined groove 1451 having a first rounded surface 1452 disposed on the pressing portion 145, the inclined groove 1451 is sequentially connected to an end surface of the supporting portion 147 and an end surface of the first bending portion 148, the pressing portion 145 is further provided with a second rounded surface 1453 spaced apart from the first rounded surface 1452, and the first rounded surface 1452 and the second rounded surface 1453 have a common center. By providing the inclined groove 1451 and the concentric first and second rounded surfaces 1452 and 1453, the elastic deformation of the ground guiding portion 210 under the action of the rotating pressing plate 130 can be increased, and the elastic deformation can be generated relative to a certain constant force arm, so that the deformation stability is high.

Referring to fig. 2 and fig. 3, specifically, as an embodiment of the plugging portion 144, the plugging portion 144 is disposed on a side of the pressing portion 145 opposite to the supporting portion 147 and extends in a direction parallel to the fixing portion 141, and when the elastic deformation of the plugging portion 144 is not generated in the initial state, a bottom surface of the plugging portion 144 corresponding to the position of the opening 220 is lower than the bottom surface of the pressing portion 145 and higher than the upper surface of the flat cable 200, so that the plugging and unplugging of the flat cable 200 are not interfered. Because the extending direction of the inserting portion 144 is parallel to the inserting direction, under the pressing action of the pressing plate 130, the pressing portion 145 receives the pressing action of the pressing plate 130 to make the inserting portion 144 move towards the opening 220 in an elastic deformation manner, so that the bottom surface of the inserting portion 144 at least partially enters the opening 220, and the free end surface of the inserting portion 144 can abut against the opening end surface of the opening 220.

Referring to fig. 4 and 5, specifically, as another embodiment of the insertion portion 144, the metal elastic sheet 140 further includes a pressed portion 1410, it can be seen that, for the two embodiments of the insertion portion 144, the elastic portion 146 and the supporting portion 147 with the same structure are both adopted, two ends of the elastic portion 146 are respectively connected to the top of the fixing portion 141 and the pressed portion 1410, and with respect to the insertion direction of the flat cable 200 into the accommodating space, the insertion portion 144 is disposed at a position relatively far away from the end where the pressed portion 1410 is connected to the elastic portion and extends toward the direction far away from the platen 130, so that the distance between the end of the pressed portion 1410 and the connection provides a moment for the insertion portion 144 to generate a large elastic deformation. The free end surface of the insertion portion 144 includes an inclined surface located at the front end in the insertion direction, and the pressure receiving portion 1410 receives the pressing force of the pressure plate 130 to move the insertion portion 144 toward the opening 220 in an elastically deformed manner, so that the inclined surface abuts against the first port end surface 221 of the opening 220.

Referring to fig. 9, preferably, the free end surface further includes an arc surface (not shown) opposite to the inclined surface, and the arc surface is opposite to the second port end surface 222 opposite to the first port end surface 221. Therefore, the arc-shaped surface can limit the further relative movement of the opening 220 and buffer the insertion force under the condition that the flat cable 200 is excessively inserted, thereby avoiding the damage to the conductive terminal 120.

As another objective of the present invention, the present invention further provides an electronic device, which can be, for example, a mobile phone, a computer, a car navigation instrument, etc., and which includes any one of the above electrical connectors 100, and has the effect of any one of the above electrical connectors 100, which is not described herein again.
