Description

High-speed electric connector

[ technical field ] A method for producing a semiconductor device

The embodiment of the application relates to the field of communication transmission, in particular to a high-speed electric connector.

[ background of the invention ]

The electrical connector assembly allows a user of the electronic device or external apparatus to transmit data to or communicate with other devices and apparatuses. Typically, the electrical connector assembly includes a pluggable module received within a receptacle assembly that includes a receptacle connector that is removably connectable to the pluggable module. The receptacle assembly includes a metal cage having an internal compartment that receives the pluggable module therein. A receptacle connector is retained in the interior compartment of the cage for connection with the pluggable module when the pluggable module is inserted therein.

A gigabit interface connector (GBIC) is a hot-pluggable input/output device that plugs into a gigabit ethernet port/slot responsible for connecting the port to a fiber optic network. GBIC can be used and interchanged on various Cisco products, and can be mixed port by port with IEEE 802.3z compliant 0 BaseXX, 0BaseLX/LH or 0BaseZX interfaces. Further, Cisco is offering a 0BaseLX/LH interface that fully complies with the IEEE 802.3z0BaseLX standard, but has a transmission distance on single mode fiber of up to 10 kilometers, 5 kilometers more than the common 0BaseLX interface. In summary, as new functions are continuously developed, it will be easier to upgrade these modules to the latest interface technologies, thereby maximizing customer investment.

These conventional plug-in designs have been successful in the past, but they tend not to meet the goals of continued miniaturization in the industry. It is desirable to miniaturize transceivers to increase port density associated with network connections such as switchboxes, cable patch panels, wiring closets, and computer input/output (I/O). Conventional pluggable module configurations are unable to meet these parameter requirements. It is also desirable to increase port density and optimize the connection interface of the SFP module.

A new standard has been published and is referred to herein as the hot-plug (SFP) standard, which is an abbreviation for smallformplugble, simply understood as an upgraded version of GBIC. The SFP module has a half of volume reduction compared with the GBIC module, and the number of ports which is more than one time can be configured on the same panel. The other functions of the SFP module are substantially identical to the GBIC. Some switch vendors call SFP modules as miniaturized GBIC (MINI-GBIC). The SFP module has a half of volume reduction compared with the GBIC module, and the number of ports which is more than one time can be configured on the same panel. The other functions of the SFP module are basically the same as the GBIC.

As the transmission rate of the connector is faster and faster, and the overall size of the connector is smaller, the problem of heat generation of the connector is more serious, and a connector with good heat dissipation performance needs to be designed.

The terminal module 1 includes a support body 11 and a plurality of terminals 12 combined with the support body 11. The plurality of terminals 12 include a plurality of signal terminals 121 and a plurality of ground terminals 122, the plurality of signal terminals 121 and the plurality of ground terminals 122 are arranged at specific regular intervals (for example, one ground terminal 122, two signal terminals 121, and two ground terminals 122 may be arranged in sequence along the arrangement direction), and may be arranged in other arrangement manners. The front end of the supporting body 11 defines an insertion cavity 10 for cooperating with a docking module (not shown), and each of the terminals 12 includes a contact section 1201 protruding into the insertion cavity 10, and the contact sections 1201 are arranged in two rows at two opposite sides inside the insertion cavity 10. Of course, each of the terminals 12 further includes a fixing section (not numbered) integrally connected with the contact section 1201 and correspondingly combined in the support body 11, and a docking section (not numbered) extending from a section of the fixing section far from the contact section 1201 out of the support body 11 and correspondingly contacting with the circuit board.

The support body 11 includes a terminal insulating portion 111 and an insulating cover 112, the terminal 12 is coupled to the terminal insulating portion 111, the insulating cover 112 is fitted around the periphery of the terminal insulating portion 111, the vent groove 110 is formed in the insulating cover 112, and the insertion cavity 10 is formed by recessing the front end of the insulating cover 112. The terminal insulating part 111 is formed by stacking a plurality of terminal substrates 1111 in one direction, and a signal terminal 121 or a ground terminal 122 is combined in each of the terminal substrates 1111. In this application, the terminal substrates 1111, which are combined with the terminals 12, are stacked in one direction and then inserted into the insulating housing 112 from the rear to the front (in the direction of pulling out the mating module) to form a complete terminal module 1.

The metal cover 2 includes a top wall 21, a bottom wall 22, two left and right side walls 23, and a rear end wall 24. The top wall 21 and the bottom wall 22 are oppositely disposed, and the two side walls 23 are oppositely disposed. The top wall 21, the bottom wall 22, the left and right side walls 23 and the rear end wall 24 jointly enclose the accommodating space 20 and form the insertion opening 200. A mounting hole 201 is formed between the bottom wall 22 and the rear end wall 24 to receive the terminal module 1. The insertion cavity 10 is correspondingly disposed to communicate with the receiving space 200.

Referring to fig. 1 to 7, a vent groove 110 is formed on an outer side surface of the support body 11 and is recessed inward, and the vent groove 110 extends along a plugging direction of the docking module and penetrates through the support body 11.
