Detailed Description

in order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the technical solution of the present invention will be further explained by combining the drawings and by means of the specific implementation manner. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements related to the present invention are shown in the drawings.

in order to keep the elastic sheet of the network interface connector always with good resilience, the embodiment provides a network interface connector.

Referring to fig. 2-4, in the embodiment, the network interface connector includes a shielding shell 1 and a plastic body 2 located in the shielding shell 1, the plastic body 2 encloses to form an accommodating cavity for accommodating the mating plug and having an opening at one end, and a connection terminal 4 for transmitting signals is disposed in the accommodating cavity. The shielding shell 1 plays a role of electromagnetic shielding, and prevents other electromagnetic signals from interfering the signal transmission of the network interface connector; the plastic body 2 fixes the connection terminal 4 in the accommodation cavity and plays an insulating role.

The network interface connector further comprises an elastic sheet 3, the elastic sheet 3 extends from the opening end of the accommodating cavity to the inside of the accommodating cavity, the elastic sheet 3 comprises a base portion 31, a first bending portion 32 and a second bending portion 33 which are sequentially connected, the base portion 31 is abutted to the plastic main body 2 at the opening end, the first bending portion 32 is arranged at an acute angle with the plastic main body 2, and the second bending portion 33 is arranged at an obtuse angle with the first bending portion 32 and extends towards the inside of the accommodating cavity.

The base 31 abuts against the plastic body 2, and can generate a supporting force for the first bending portion 32 and the second bending portion 33, so that the elastic sheet 3 in this embodiment has a better elastic restoring force than the linear elastic sheet in the prior art, and the elastic sheet 3 can always restore to its original shape in the process of repeated plugging and unplugging of the docking plug.

When the docking plug is inserted into the accommodating cavity, the docking plug can extrude the elastic sheet 3, the plastic main body 2 is provided with a groove 21 matched with the elastic sheet 3 in the accommodating cavity, the groove 21 extends in the same direction as the elastic sheet 3, and the base 31 abuts against the inner wall 211 of the groove 21.

Further, in the embodiment, the first bending portion 32 and the inner wall 211 of the groove 2 are disposed at an acute angle and extend out of the groove 21 in an inclined manner, so that the first bending portion 32 is extruded into the groove 21 by the docking plug after the docking plug is inserted into the accommodating cavity, and the elastic sheet 3 can generate a contact force with the docking plug.

Specifically, in the present embodiment, the second bending portion 33 is parallel to the inner wall 211. Optionally, the acute angle is between 20 ° and 45 °. Preferably, the acute angle is 45 °. When the docking plug presses the second bending portion 33, the elastic restoring force of the first bending portion 32 can make the second bending portion 33 generate a good abutting force against the docking plug, so as to ensure the stability of signal transmission, and after the docking plug is pulled out of the accommodating cavity, the elastic restoring force of the first bending portion 32 exists, so that the elastic sheet 3 can be restored.

In the process that the butt plug is inserted into the accommodating cavity, the butt plug extrudes the elastic sheet 3 into the groove 21, meanwhile, the second bending part 33 of the elastic sheet 3 is always abutted against the butt plug, and the two second bending parts 33 on the two sides are abutted against the butt plug at the same time, so that the firm contact between the butt plug and the network interface connector is ensured; when the butt plug is pulled out of the groove 21, the spring piece 3 is restored. The setting of recess 21 for when docking plug inserts the holding chamber, shell fragment 3 can be arranged in recess 21 after being extruded and warp, is unlikely to be squeezed into the linear type by the inner wall of docking plug and plastic main part 2, guarantees that when docking plug pulls out from the holding chamber after, shell fragment 3 can the reconversion.

referring to fig. 5, in other embodiments, the second bending portion 33 may further extend obliquely toward the inner wall 211, and the plastic main body 2 is provided with a locking groove 34 engaged with the second bending portion 33.

Thus, after the docking plug is inserted into the accommodating cavity, the intersection of the first bending portion 32 and the second bending portion 33 provides a stable supporting force for the docking plug, the end of the second bending portion 33 far away from the first bending portion 32 is clamped in the clamping groove 34, the clamping groove 34 provides a supporting force for the end of the second bending portion 33 far away from the first bending portion 32, and the ends of the base portion 31 and the second bending portion 33 far away from the first bending portion 32 can provide a stable supporting force for the elastic piece 3. With this arrangement, on the one hand, the abutting force generated at the intersection of the first bent portion 32 and the second bent portion 33 is more stable; on the other hand, the elastic restoring force of the elastic sheet is better.
