Description

Technical Field

[0001] The present invention relates to the technical field of electric connectors, and in particular to providing an electric connector shielding spring. Background Art

[0002] Electromagnetic interference can cause signal interception and data loss, affecting the normal operation of electronic equipment. As electronic equipment becomes more complex, smaller in size, and higher in precision, shielding electromagnetic interference is becoming increasingly important to ensure the normal operation of highly integrated electronic equipment.

[0003] Existing connector shielding electromagnetic interference technology mostly uses the addition of shielding springs. The shielding springs can be welded, bonded or snapped onto the connector. The welding process is complicated, and the bonding process has poor conductivity. The snap-on type uses the shielding spring to assemble the inner wall of the socket body, but the shielding spring is easy to fall off or misplace with many plugging and unplugging times, affecting the shielding effect. Therefore, it is necessary to provide a device with simple process, good conductivity and shielding spring that can be fastened to the connector. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an electrical connector shielding spring to solve the technical problem of shielding interference signals without dead angles in the connector.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Preferably: an electrical connector shielding spring, comprising a socket body, a spiral shielding spring and a connection component for transmitting signals, wherein: a trapezoidal groove is arranged around the top of the outer wall of the socket body to match the spiral shielding spring, an rib is arranged on the upper and lower sides around the trapezoidal groove, the bottom surface of the trapezoidal groove is the back, the rib is inverted on the spiral shielding spring to make it resist the back, so that the spiral shielding spring is tightly attached to the trapezoidal groove.

[0007] Preferably, the edge-extruding portion is inclined from the trapezoidal groove opening toward the side wall of the trapezoidal groove, and a rectangular installation opening is reserved between the edge-extruding portions at the corner of the trapezoidal groove.

[0008] Preferably: the backs are connected by a positioning platform, the positioning platform comprises an upper positioning platform and a lower positioning platform, and a curved surface is formed between the upper positioning platform and the lower positioning platform.

[0009] Preferably, the spiral shielding spring is arranged with spiral gaps at equal intervals, and the corners are designed with arcs to fit the curved surface.

[0010] Preferably, the positioning platform tightly holds the four corners of the spiral shielding spring to prevent the spiral shielding spring from falling off easily.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When using the electrical connector shielding spring, the spiral shielding spring is tightly fastened in the trapezoidal groove according to the shape of the trapezoidal groove, which can ensure 360° shielding of electromagnetic interference. At the same time, the spiral shielding spring is installed on the outer wall of the socket shell, and the shielding spring will not be brought out when the connector connection component is plugged in or unplugged.

[0027] In one embodiment, referring to the accompanying drawings Figures 1 to 4 , the figure shows an electrical connector shielding spring, including a socket body 10, a spiral shielding spring 20 and a connecting assembly 30 for transmitting signals;

[0028] The socket body 10 is integrally formed, and a trapezoidal groove 11 is provided at the top of the plug-in outer wall. The trapezoidal groove includes a back 111 at the bottom of the groove, and ribs 112 on the upper and lower sides. The corners of the trapezoidal groove are designed with arcs. The backs are connected at the corners by a positioning platform 113 and a curved surface 114. The positioning platform is divided into an upper positioning platform and a lower positioning platform. There is a curved surface between the upper positioning platform and the lower positioning platform. The ribs 112 are not connected at the corners, thereby reserving a rectangular installation opening for easy installation and removal of the spiral shielding spring.

[0029] The spiral shielding spring 20 is made of flexible material and is adapted to the trapezoidal groove 11. The four sides thereof are arranged with spiral gaps at equal intervals. When the spiral shielding spring is assembled into the trapezoidal groove, it pops open. At this time, the spiral shielding spring is inverted between the edge extrusion parts 112 on the upper and lower sides, so that the four sides of the spiral shielding spring are against the back 111. At the same time, the spiral shielding spring is clamped into the clamping platforms 113 on the upper and lower sides at the corners and is close to the curved surface 114.

[0030] The spiral shielding spring 20 is assembled to the outer wall of the socket body 10 , which not only shields the interference signal 360° without blind spots, but also does not affect the plugging and unplugging of the connecting component 30 .
