Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to an electric connector structure. Background Art

[0002] As people's demand for convenient application of electronic products becomes more and more obvious, it has attracted the continuous attention of various manufacturers. In order to improve the competitiveness of electronic products, various manufacturers must continuously strengthen and expand the functions of electronic products. Therefore, in addition to moving towards a thin and short appearance, the structure and transmission speed of various electronic products must also be continuously improved to improve the user's operating convenience.

[0003] Since the electrical connector structure is used to connect electronic products or components within electronic products for signal transmission, the importance of the electrical connector structure in electronic products is beyond words. How to make the electrical connector structure easy to assemble during manufacturing and reduce assembly costs while taking into account the effectiveness of the electrical connector structure has become a competition among manufacturers.

[0004] Among electronic connectors, the USB specification connector has also made the biggest breakthrough. The USB universal serial bus is a serial bus standard for connecting external devices. It is widely used on computers and is the most common specification. It can also be used on set-top boxes and game consoles. Even many industrial instruments are connected to computers through USB. USB can not only provide data transmission for peripheral devices, but also power supply. The On-The-Go plug-and-play feature allows portable devices to directly exchange data.

[0005] USB was initially based on the USB1.0 specification, with a transmission speed of 1.5Mb / s. In 1998, the USB2.0 specification was introduced, and the transmission speed was increased to 12Mb / s. This specification has been widely used in electronic products, and the latest USB3.0 specification has increased the transmission speed to 5.0Gb / s, which is more than 10 times that of the USB2.0 specification. Since the speed is much faster than before, it has become the mainstream specification now.

[0006] Therefore, as USB 3.0 products are now mainstream, how to make USB 3.0 products easy to manufacture and apply to thin and small electronic devices has become an urgent problem that manufacturers need to overcome.

[0007] As the amount of data transmitted increases, corresponding electromagnetic radiation may be generated during use, thereby interfering with the normal operation of other electronic components. In view of this, the industry generally uses grounding to reduce the generation of electromagnetic interference (EMI).

[0008] However, since the USB 3.0 interface has a large number of conductive terminals and its size is getting smaller, how to overcome the generation of electromagnetic interference (EMI) within the limited space will be an urgent problem that this product needs to overcome.

[0009] It can be seen that the commonly used structures listed above still have many shortcomings and are in urgent need of improvement. Utility Model Content

Figures 1 to 7 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0048] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0049] In one embodiment of the present invention, Figures 1 to 6 As shown, an electrical connector structure is provided, which includes an insulating body 1, a plurality of conductive terminals 2 and a plurality of grounding terminals 3.

[0050] The insulating body 1 is a flat rectangular structure, and is provided with a plurality of terminal accommodating grooves 11. Specifically, the terminal accommodating grooves 11 are arranged in two rows, and the number is four and five respectively, so as to meet the USB3.0 specification; in addition, a ground terminal accommodating groove 12 is further provided on both sides of the insulating body 1;

[0051] A plurality of conductive terminals 2 are disposed in the insulating body 1, and include a contact portion 21 exposed on the top surface of the insulating body 1, a fixing portion (not shown) embedded in the insulating body 1, and a welding portion 22 exposed at the rear end of the insulating body 1; wherein the contact portion 21 is located in the terminal receiving groove 1, and the welding portion 22 is exposed and extends toward the rear end of the insulating body 1; the overall structure of the conductive terminal 2 of the present invention meets the USB3.0 specification and will not be described in detail herein.

[0052] A plurality of grounding terminals 3 are disposed in the grounding terminal accommodating grooves 12 on both sides of the insulating body 1, and include a welding portion 31 extending toward the bottom of the insulating body 1 and exposed at the bottom of the insulating body 1, a grounding portion 32 extending toward both sides of the insulating body 1, and a fixing portion 33 connecting the welding portion 31 and the grounding portion 32 and embedded in the insulating body.

[0053] To further explain in detail, the welding portion 31 of the grounding terminal 3 is arranged at the front end position, and is extended and bent downward to be exposed and located on the bottom surface of the insulating body 1; and the grounding portion 32 is arranged in two in this embodiment, namely a first grounding portion 321 close to the front end position (away from the welding portion direction of the conductive terminal) and a second grounding portion 322 close to the welding portion direction of the conductive terminal. If viewed from a top view, the first grounding portion 321 and the second grounding portion 322 are arranged one above and one below, and the width of the outermost edge of the grounding portion 32 is slightly larger than the width of the insulating body 1.

[0054] The substrate 4 is a circuit board, and the substrate 4 is provided with electrical conductive parts 41 for welding the conductive terminals 2 and the grounding terminals 3, so that the insulating body 1 can be welded and fixed on the substrate 4 through the conductive terminals 2 and the grounding terminals 3, and is electrically conductive with the substrate 4.

[0055] The metal shell 5 is coated on the outside of the insulating body 1 and the substrate 4. After coating, the grounding portion 32 of the grounding terminal 3 is in contact with the inner surface of the metal shell 5, so that the electromagnetic interference (EMI) generated by the telecommunication transmission can be guided out through the metal shell.

[0056] In order to allow Jun Ju to further understand the structural features of the present invention, it is specifically explained here that the first grounding portion 321 of the grounding terminal 3 is an outwardly protruding sheet structure, and the second grounding portion 322 is an elastic arm structure extending outward. Therefore, when the first grounding portion 321 and the second grounding portion 322 are in contact with the inner side of the metal shell 5, the first grounding portion 321 is tightly fitted with the metal shell 5, and the second grounding portion 322 is in elastic contact with the metal shell 5, thereby ensuring that the grounding portion 32 of the grounding terminal 3 can be truly overlapped with the metal shell 5, which can avoid the grounding terminal 3 not contacting the metal shell 5 due to tolerances generated during manufacturing, thereby losing the function of eliminating electromagnetic interference.

[0057] In addition, the best implementation of the electrical connector of the present invention is to be applied to a USB flash drive product, and the USB flash drive shell is made of metal. Therefore, it is only necessary to insert and fix the insulating body 1 and the substrate 4 of the present invention at the plug interface to complete the same structure and function as the present invention.

[0058] Please see again Figure 7 As shown, in the present embodiment, the structure of the first grounding portion 321 is the same as that of the second grounding portion 322, which is an elastic arm structure extending outward. The elastic arm structure can avoid the problem of the grounding portion 32 of the grounding terminal 3 not contacting the metal shell 5 due to the tolerance of production, and can greatly ensure the stability of the overlap between the grounding terminal 3 and the metal shell 5.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
