[0021] In order to make the content of the utility model more clearly understood, the utility model is further described below based on specific embodiments in combination with the accompanying drawings.

[0022] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0023] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0024] like Figures 1 to 4 As shown, the utility model proposes a double-layer multi-contact connector, including a connector body 1 and a protective plate 4. Two plug-in interfaces 2 are provided on one side of the connector body 1, and a plurality of terminals 3 are convexly provided on the other side. One end of the terminal 3 extends into the interior of the connector body 1 and is connected to the plug-in interface 2; the protective plate 4 is movably connected to the side of the connector body 1 where the terminal 3 is provided, and a plurality of through holes 5 are opened on the protective plate 4 corresponding to the terminals 3. The terminals 3 pass through the through holes 5, and the protective plate 4 can slide along the terminals 3 and cover them.

[0025] It can be understood that the connector body 1 is provided with plug-in interfaces 2 arranged in upper and lower layers for plugging in the HDMI data cable, and a plurality of protruding terminals 3 are provided on any other side surface. In this example, a side surface adjacent to the surface where the plug-in interface 2 is located is selected. One end of the terminal 3 is connected to the plug-in interface 2 in the connector body 1, and the other end protrudes outside for insertion into the socket on the circuit board to transmit the signal. The HDMI technology is a prior art and will not be described further here.

[0026] The terminal 3 is provided on one side of the connector body 1 and is also movably connected with a protective plate 4, which has through holes 5, through which the terminals 3 pass. The protective plate 4 can slide along the bottom of the terminal 3 to the tip of the terminal 3, and the terminal 3 is covered in the protective plate 4, which can prevent the terminal 3 from being directly exposed to the outside. On the one hand, the staff will not be stabbed by the sharp terminal 3 when taking the connector, thereby improving the safety factor. On the other hand, the terminal 3 can be protected from bending and deformation due to external forces such as collision and extrusion, and it is relatively smooth when plugging with the circuit board. In addition, during the process of plugging the circuit board, the terminal 3 may also be bent due to the misalignment of the plug hole. At this time, the protective plate 4 can be slid along the bottom of the terminal 3 to the tip of the terminal 3 once or more times, and the terminal 3 will return to its original state under the action of the through hole 5, so that the same connector can continue to be used without replacing it with a new one, which helps to save costs.

[0027] like Figure 3 As shown, in one embodiment of the present application, a side surface of the connector body 1 on which the terminal 3 is provided is provided with a receiving groove 6 , and the protective plate 4 is fittedly disposed in the receiving groove 6 .

[0028] It can be understood that the accommodating groove 6 is provided so that when the terminal 3 is plugged into the circuit board, the protective plate 4 can be placed in the accommodating groove 6. The surface of the protective plate 4 is on the same horizontal plane as the side of the connector body 1 and will not protrude outside to affect the plugging, thereby making the plugging between the connector and the circuit board more secure.

[0029] like Figure 3 As shown, in one embodiment of the present application, active cavities 61 are provided on both sides of the accommodating groove 6 , and adjusting portions 7 are provided at both ends of the protective plate 4 corresponding to the active cavities 61 , and the adjusting portions 7 are inserted into the active cavities 61 .

[0030] It can be understood that through the above-mentioned arrangement, the adjusting part 7 can slide in the movable cavity 61, thereby driving the protective plate 4 to slide so that it covers the terminal 3. The movable cavity 61 and the adjusting part 7 are completely in shape, so that the two have a greater friction when sliding, so that the protective plate 4 can resist part of the external force impact when covering the terminal 3 and will not slide easily; further, the fitting surface of the adjusting part 7 and the movable cavity 61 can also be provided with a pattern to continue to increase the friction, so that the protective plate 4 will not slide easily.

[0031] like Figures 1 to 4 As shown, in one embodiment of the present application, two slide grooves 62 are formed on the outer wall of the active cavity 61 , and the adjustment portion 7 is provided with two levers 71 corresponding to the two slide grooves 62 . The two levers 71 pass through the two slide grooves 62 and partially protrude outside.

[0032] It can be understood that the provision of the slide groove 62 and the lever 71 can, on the one hand, make it convenient for the user to move the protective plate 4 through the lever 71, and on the other hand, can also limit the moving direction of the protective plate 4 so that it can only move along the direction of the slide groove 62, and will not move in other directions to cause the terminal 3 to bend. Moreover, since the movable distance of the protective plate 4 is equal to the length of the slide groove 62, the user can set the slide groove 62 of different lengths according to the protruding length of the terminal 3 on different connectors to better protect the terminal 3.

[0033] The number of the levers 71 is set to two, which can make the force transmitted to the adjustment part 7 more uniform, and the user can move the protective plate 4 more easily and labor-savingly.

[0034] like Figure 4 As shown, in one embodiment of the present application, a paddle 72 is connected between one end of the two paddle rods 71 ​​protruding out of the slide slot 62 .

[0035] It can be understood that the setting of the paddle 72 can facilitate the user to paddle the lever 71. The force applied by the user to the paddle 72 can be transmitted to the levers 71 at both ends at the same time, so that the force on the adjustment part 7 is more uniform, and it is easier and more labor-saving for the user to paddle the protective plate 4. In addition, the paddle 72 can also prevent the lever 71 from escaping from the slide groove 62 and causing the protective plate 4 to detach from the connector body 1.

[0036] like Figure 1 to Figure 2 As shown, in one embodiment of the present application, the length of the slide groove 62 is equal to the length of the protruding portion of the terminal 3 .

[0037] It can be understood that since the movable distance of the protective plate 4 is equal to the length of the slide groove 62, the length of the slide groove 62 is set to be consistent with the protruding length of the terminal 3, so that when the user pushes the lever 71 to the bottom of the slide groove 62, the protective plate 4 is exactly at the tip of the terminal 3, which completely protects the terminal 3 and prevents the terminal 3 from slipping out of the through hole 5.

[0038] To sum up, the beneficial effects of this embodiment are as follows: this embodiment provides a protective plate 4 on one side of the connector where the terminal 3 is provided, and a through hole 5 is opened on the protective plate 4. The terminal 3 passes through the through hole 5, and the protective plate 4 is slid along the terminal 3 so that the terminal 3 can be covered by the protective plate 4, thereby preventing the terminal 3 from being directly exposed to the outside and injuring the staff. At the same time, it provides a certain protection for the terminal 3 to prevent it from being bent by external force, and can also correct the bent terminal 3 to a certain extent, thereby increasing its service life.

[0039] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
