Description

Technical Field

[0001] The utility model belongs to the technical field of USB connectors, in particular to a USB connector with a filtering function. Background Art

[0002] The traditional USB connector used to charge mobile phones, digital cameras, etc. does not have the function of filtering the charging current. When unplugging and plugging the charger, a large impact current will be generated, which is easy to damage the circuit boards of mobile phones, digital cameras, etc., greatly reducing the service life of electronic products such as mobile phones and digital cameras. The maintenance cost is high, which brings great inconvenience to users. In addition, the traditional USB connector used to charge mobile phones, digital cameras, etc. does not have shielding and fast charging functions. Electromagnetic interference will be generated between the electronic components of the USB connector, affecting the use of the equipment. For example, people often have the habit of listening to music or making calls on their mobile phones while charging. In the absence of a shielding function, noise caused by electromagnetic interference is often heard when listening to music or making calls, which affects the effect of people listening to music and making calls.

[0003] The prior art has a connector with a filtering function, which is provided by announcement number CN204760668U. The terminals are connected to the filtering PCB board by welding. However, in the existing use, the charging cable often fails to be used suddenly. After disassembly and inspection, it is found that the welding point is poorly soldered or the wire is bent during use, causing the welding point to fall off. Utility Model Content

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Example 1

[0024] Reference Figure 1 to Figure 3 The present embodiment provides a USB connector with a filtering function, including a rubber core 100, a conductive terminal 101 is arranged in the rubber core 100, a conductive strip 102 is arranged at one end of the conductive terminal 101, and a connecting elbow 103 is arranged downward at the end of the conductive strip 102; the filter board 200 is a PCB board, and a conductive sheet 201 is arranged on the filter board 200, and the conductive sheet 201 is connected to the connecting elbow 103.

[0025] It should be noted that the filter board 200 plays a specific filtering role. During the charging process of electronic products, a large current is filtered through the filter board 200, which can prevent damage to the electronic products due to excessive current during charging, effectively extend the service life of the electronic products, have low maintenance costs, and are easy to use. The filtering structure composition and principle are existing technologies and will not be repeated here.

[0026] The conductive sheet 201 can be connected to the conduction point on the filter board 200 by welding. Since the conductive sheet 201 is a sheet structure, the conduction point is covered and then fixed by crimping the connecting elbow 103 .

[0027] A ground terminal 202 is disposed on the side of the filter board 200 .

[0028] The ground terminal 202 is connected to the metal shell 300 to provide a shielding function to avoid electromagnetic interference.

[0029] The invention also includes a metal shell 300 , in which the plastic core 100 is embedded.

[0030] The metal shell 300 further includes an insulating shell 400 , which is connected to one end of the metal shell 300 .

[0031] A pressing plate 401 is disposed in the insulating shell 400 , and the pressing plate 401 is pressed onto the conductive strip 102 .

[0032] In this embodiment, after the insulating shell 400 is connected to the metal shell 300 , the pressing plate 401 is located above the conductive strip 102 and presses down the end of the conductive strip 102 so that the connecting elbow 103 and the conductive sheet 201 are always connected.

[0033] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
