Background

With the development of electronic technology, various electronic products such as: televisions, computers, smart phones, various communication devices, and the like have become increasingly popular. The accompanying disadvantage is that the living environment is filled with electromagnetic waves generated by various electronic products, and therefore, the electronic products have been receiving attention from governments and enterprises in terms of electromagnetic interference and transmission tolerance.

The consumer products have more obvious signal transmission interference between the wireless network base station and the third generation universal serial bus (USB 3.0). In order to solve the problem of electromagnetic wave signal interference, an electromagnetic shielding cover is disposed around the existing third generation universal serial bus (USB3.0) connector to reduce the leakage of electromagnetic waves. However, most of the conventional electromagnetic shielding cases are made of metal (tin plate) and Dual In Line Package (DIP) process, which requires much manufacturing and labor cost. Furthermore, the conventional electromagnetic shielding case still has a plurality of pores on the whole structure, so that part of the electromagnetic waves can be transmitted to the environment from the pores, and the efficacy of the electromagnetic shielding is affected.

In addition, the appearance of the conventional electromagnetic shielding case is also easy to cause static electricity accumulation, and finally, the problem of electrostatic discharge is caused, so that the function of transmitting signals is lost, which indicates that the grounding performance of the conventional electromagnetic shielding case is insufficient.

The base is provided with a slot and is suitable for being fixed on the circuit board. The transmission interface is provided with a clamping part and a plug board. The clamping part is clamped in the slot, and part of the inserting plate protrudes out of the base. The shielding cover is provided with an accommodating space. The accommodating space is used for accommodating the base and the transmission interface. The shielding layer is electrodeposited on an inner side surface of the shielding cover, and the shielding cover covers the base and the transmission interface and is used for blocking electromagnetic waves generated by the transmission interface.

Based on the above, the connector of the present invention is divided into the base, the transmission interface and the shielding cover. The base is suitable for being welded on the circuit board by adopting Surface Mount Technology (SMT), and the SMT Technology can be automatically installed through a machine to replace the past manual installation so as to achieve the purposes of reducing the manufacturing cost and improving the product yield.

Detailed Description

Fig. 1 is a schematic plan view of a connector according to an embodiment of the present invention. Fig. 2 is an exploded schematic view of the components of the connector of fig. 1. Fig. 3 is a schematic diagram in plan perspective of the transmission interface of fig. 2.

Referring to fig. 1, the connector 100 of the present embodiment is suitable for being disposed on a circuit board. The connector 100 is, for example, a third generation universal serial bus (USB3.0/3.1) for connecting a connector or a flash drive with a corresponding specification, and is suitable for supplying power or transmitting electronic signals. In other embodiments, the connector may be other types of buses, and is not limited to a third generation universal serial bus (USB 3.0/3.1). Additionally, a bus refers to a standardized way of exchanging data between computer components, i.e., providing data transfer and control logic for each component in a common manner.

Referring to fig. 1 to fig. 3, in detail, the connector 100 of the present invention includes a base 110, a transmission interface 120, a shielding cover 130, and a shielding layer 131.

The base 110 has a slot S and a plurality of first pins 111. The socket S is concavely formed on the top surface of the base 110. The first pins 111 respectively extend from the inside of the slot S to the outside of the base 110. The first pins 111 correspond to standard pins (+, -, D +, and D-) of a third generation usb, respectively. The first pins 111 are suitable for being soldered on the circuit board 200 by Surface Mount Technology (SMT) to electrically connect the circuit board 200.

The transmission interface 120 has a plug board 121, an engaging portion 122 and a plurality of second pins 123. The engaging portion 122 extends downward (i.e., in the direction of the base 110) and is engaged in the slot S. A portion of the board 121 protrudes out of the base 110, i.e. the board 121 protrudes out of the base 110 along a horizontal direction PD. The engaging portion 122 is perpendicular to the insertion plate 121 to present an L-shaped appearance. The second pins 123 respectively extend from the board 121 to the engaging portion 122, and are also L-shaped, and the second pins 123 are respectively electrically coupled to the corresponding first pins 111.

Furthermore, the board 121, the engaging portion 122 and the second pins 123 are integrally formed, and for example, an injection molding technique is adopted, so that the second pins 123 are embedded in the board 121 and the engaging portion 122.

In addition, the shape and size of the engaging portion 122 correspond to those of the slot S, and are suitable for being engaged with each other. For example, to improve the structural stability of the transmission interface 120 connected to the base 110, the length of the engaging portion 122 may be increased, and the depth of the slot S may be correspondingly increased. So that the L-shaped structure of the transmission interface 120 can resist the external force of plugging and unplugging other elements.

The shielding cover 130 has an accommodating space AS and a plurality of positioning pillars 132. The receiving space AS is used for receiving the base 110 and the transmission interface 120, and the shielding layer 131 is disposed on an inner side surface of the shielding cover 130, for example, the shielding layer 131 is electrodeposited on the inner side surface of the shielding cover 130. The positioning posts 132 are disposed outside the accommodating space AS, and the positioning posts 132 are suitable for being soldered on the circuit board 200. To completely cover the base 110 and the transmission interface 120.

Furthermore, a case shield and a slit shield are often used to suppress Electromagnetic Interference (EMI). Isolating interference generating circuits by shielding, filtering or grounding, enhancing the interference resistance of sensitive circuits, and the like. The material of the shielding layer includes, for example: metal cans, thin metal sheets, foil strips, conductive fabrics, coatings (such as conductive paint and zinc wire spray coating) and coatings (electrodeposition, vapor deposition of metal materials).

Wherein the base 110 is adapted to be fixed on the circuit board 200. When the shielding cover 130 covers the base 110 and the transmission interface 120, the shielding cover 130 and the shielding layer 131 are used to block the electromagnetic waves generated by the transmission interface 120.

Referring to fig. 1 to fig. 3, the connector 100 further has an outer frame 140, which is disposed outside the plug board 121 of the transmission interface 120 and is adapted to contact the inner side surface of the shielding cover 130, wherein the length of the outer frame 140 corresponds to the extension length of the plug board 121, and is adapted to completely cover the peripheral portion of the plug board 121, and only an opening for connecting an external component is reserved, thereby reducing the transmission path of the electromagnetic wave to a minimum.

Further, the outer side of the outer frame 140 is configured with a conductive layer 141 adapted to be electrically coupled to the shielding layer 131 of the shielding cover 130 to achieve the grounding effect, so as to reduce the electromagnetic interference generated by the transmission interface 120.

In addition, the shielding cover 130 is made of Liquid Crystal Polymer (Liquid Crystal Polymer), and has better mechanical properties and heat resistance compared to the existing engineering plastics. For example, Liquid Crystal polymers (Liquid Crystal polymers) can be used continuously at an ambient temperature of 230 to 300 ℃ without loss of mechanical strength, and have excellent flame retardancy, which can provide protection against flame failure and spontaneous combustion when subjected to combustion conditions.

Since the shielding cover 130 of the present embodiment is made of Liquid Crystal Polymer (Liquid Crystal Polymer), it has better insulating property and dielectric strength much higher than that of the existing metal material, so that compared with the existing metal shielding cover, it can avoid Electrostatic Discharge (ESD) phenomenon, thereby reducing the possibility of damaging the device or the connector 100.

In summary, the connector of the present invention is divided into the base, the transmission interface and the shielding cover. The base is suitable for being welded on the circuit board by adopting Surface Mount Technology (SMT), and the SMT Technology can be automatically installed through a machine to replace the past manual installation so as to achieve the purposes of reducing the manufacturing cost and improving the product yield. Furthermore, the invention adopts the shielding cover to accommodate and cover the base and the transmission interface, and adds the shielding layer in the shielding cover to block the electromagnetic wave of the transmission interface, so that most of the electromagnetic wave can be limited in the accommodating space, and the electromagnetic interference caused by the outward transmission to other electrical appliances is avoided.

In addition, the shielding layer made of metal materials is formed in the shielding cover through electrodeposition, and the grounding characteristic of the shielding layer is enhanced, so that the electromagnetic wave suppression effect on the transmission interface is enhanced.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
