Electronic connector

The present invention is an electronic connector with a shielded housing SAS (Serial Attached SCSI) transmission interface.

In recent years, the rapid changes in technology, the rapid development of cloud technology, followed by the transmission of large amounts of data, at this time the connector transmission information has become an indispensable key technology, from the early SCSI ( S mall C omputer S ystem I nterface) to the current SAS (Serial Attached SCSI, Serial SCSI), the demand for high-speed information access technology to solve the bottleneck of traditional serial parallel technology provides faster signal transmission function and can support SAS and SATA with (Serial Advanced Technology Attachment) is device compatible and has a wide range of advantages.

When the connector is docked, if the structure of the plug and the socket is not properly designed to guide the alignment device, the tongue of the plug may not be accurately inserted into the docking cavity of the socket or the insertion angle is too large, so that the terminal is deformed or bent. In this case, this situation not only increases the time for connector docking, but is more likely to cause damage to the plug or socket.

In order to overcome the problem of the alignment of the plug and the socket when the connector is docked, the US Pat. No. 7,143,461 discloses a socket connector A. The socket connector A is provided with a guiding portion B and a socket portion C. Part B is a cavity formed by four side walls (not shown) (not shown), each of the two side walls is a group of parallel to each other, wherein a pair of parallel sides extend two legs B2 respectively, a stepped gap B3 is formed between the two pins B2, and the other group One of the side walls of the side wall protrudes outwardly from the side of the cavity to form a pair of positions B1. The aligning portion B1 protrudes from the outer surface of the side wall, and a recessed space is formed on the side of the side wall of the side wall (not shown) The aligning portion B1 is provided with a plurality of openings (not shown); the socket portion C includes a body (not shown), a plurality of terminals C2 and a casing C3, and the body is made of an insulating material. The main body has a pair of connecting cavities (not shown) and a plurality of terminal slots (not shown). The terminal slots are disposed on opposite sides of the mating cavity, and the plurality of terminals are assembled in the terminal slots of the body. And the soldering legs of the terminals C2 extend out of the body, the outer casing C3 has four side plates (not shown) covering the body, and the outer casing C3 has two bosses C1 disposed on the outer surfaces of the pair of parallel side plates of the outer casing The guiding portion B and the socket portion C are both fixed on a circuit board (not shown), and the guiding portion is The stepped indentations B3 of the B are respectively clamped and fixed to the respective bosses C1 of the socket portion C. The cavity of the guiding portion B is adjacent to the mating cavity of the socket portion C, and the cavity and the pair The openings of the cavities are all facing in the same direction.

When the socket connector A is docked with a plug connector (not shown), the plug connector is guided by the aligning portion B1 of the guiding portion B, and the recessed space generated by the aligning portion B1 can be The plug connector is docked, and the fastening structure (not shown) on the plug connector can be guided to the correct position by the structural design of the alignment portion B1, thereby smoothly connecting the plug connector to the socket portion C. Docking, reducing the time wasted when the socket connector A and the plug connector are docked, and avoiding structural damage caused when the socket connector A and the plug connector are incorrectly aligned.

However, in the foregoing technology, the socket connector A only relies on the guiding of the structure of the alignment portion B1 on the guiding portion B, and the precise guiding and alignment cannot be completely achieved. In the design of the mating matching of the two structures, most of the design in size is not a tight assembly fit, and some buffer space is reserved to avoid errors in the manufacturing process, which may result in structural docking that cannot be matched or too much. Too tightly matched, resulting in inability to smoothly engage, so under such a design, the socket connector A and the plug connector still cannot completely solve the problem of alignment when docking, and the socket connector A still exists. If the angle of the plug connector is too large, it may easily cause damage to the terminals, which may affect the service life of the connector.

Since the prior art fails to provide an improved method of preventing the insulating housing of the receptacle connector from being scratched to meet the actual needs of the industry, it is desirable to provide an improved technical solution to overcome the dilemma.

The purpose of the present invention is to provide an electronic connector having a shielded housing that can effectively guide the docking connector to interface with the electronic connector when the electronic connector is mated with the mating connector. The problem of the offset of the docking angle when the two connectors are docked is overcome.

The rectangular design of the groove structure 722B accommodates the arc design of the protruding structure 613B, so that the groove structure 722B The protruding structure 613B is matched to perform a finer guiding alignment to guide the electronic connector 1 to be inserted at a relatively correct angle when the electronic connector 1 is docked with the mating connector 7, so as to avoid the terminal being offset due to excessive offset of the mating angle. The damage is increased, and the service life of the electronic connector is increased. The shape of the groove structure 722B and the convex structure 613B are not limited to a circular arc shape, and may be designed as a triangle, a rectangle or even a polygonal structure.

When the electronic connector 1 is mated with the mating connector 7, the portion of the mating connector 7 adjacent to the tongue 71 is disposed in the receiving space 65. The extending portions 64 of the shielding housing 6 are respectively Covering the top plate 21 and the bottom plate 22 of the insulative housing 2, since the shielding case 6 is made of a metal material, the shielding case 6 provides a better electromagnetic shielding function, and the shielding case 6 can be separated. Internal and external, the external noise can be effectively isolated without disturbing the transmission of the signal, and the shielding case 6 can ground the noise generated by the fixed pin 641 when the high frequency signal is transmitted, thereby effectively reducing the noise. Electromagnetic noise interference provides better signal transmission quality.

Compared with the prior art, the present invention utilizes the electronic connector 1 to connect the guiding structures 613 in the shielding housing 6 and the matching structures 722 on the body 72 of the docking connector 7 as two connectors. The guiding structure 613 and the matching structures 722 have a structure for accommodating and guiding each other, and the guiding structures 613 and the matching structures 722 each have at least one structure guiding the opposite sides. The guiding design of the plurality of structures can effectively limit the error to minimize the angle at which the tongue plate 71 is inserted into the mating cavity 25 when the docking is performed. The degree of displacement and the positional offset can prevent the damage and deformation of the conductive terminals 3 of the electronic connector 1 due to the excessive offset of the insertion angle of the tongue plate 71, so that the two connectors are more smoothly connected, and the electronic device is effectively improved. The life of the connector 1 is used, and the electronic connector 1 is made more suitable for the needs of a wide range of users.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application. However, the above descriptions are only preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the content of the creation specification are All should remain within the scope of this creation patent.
