Hot plug type interface connectorTechnical Field
The present invention relates to a hot plug connector, and more particularly to a hot plug connector with conductive terminals.
Background
Gigabit interface connectors (GBICs) are hot-plugged input/output devices that plug into gigabit ethernet ports/slots, responsible for connecting the ports to the fiber optic network. GBIC can be used and interchanged on a variety of Cisco products and can be mixed with 1000BaseSX, 1000BaseLX/LH or 1000BaseZX interfaces compliant with IEEE 802.3z on a port-by-port basis. Furthermore, cisco is providing a 1000BaseLX/LH interface that is fully compliant with the IEEE 802.3z1000BaseLX standard, but that is traveling up to 10 kilometers over single mode fiber, 5 kilometers farther than the normal 1000BaseLX interface. In summary, with the continued development of new functions, it will be easier to upgrade these modules to the latest interface technology, thereby enabling the customer investment to take maximum advantage.
These traditional plug-in designs have been successful in the past, but they tend not to achieve the industry's continuing goal of miniaturization. It is desirable to miniaturize transceivers to increase the port density associated with network connections such as distribution boxes, cable patch panels, wiring closet, and computer input/output (I/O). Conventional pluggable module configurations are not able to meet these parameter requirements. It is also desirable to increase port density and optimize the connection interfaces of the SFP modules.
A new standard has been published and is referred to herein as the hot plug (SFP) standard, which is an abbreviation for SMALL FORMPLUGGABLE, which can be simply understood as an upgraded version of GBIC. The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. Other functions of the SFP module are substantially identical to GBIC. Some switch manufacturers call SFP modules miniaturized GBICs (MINI-GBICs). The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. The other functions of the SFP module are essentially the same as GBIC.
In the prior art, a single-layer hot plug socket connector is mostly provided with an upper row of terminals and a lower row of terminals, and 10 terminals are arranged in each row, but with the continuous improvement of the state of the art, the prior art needs to be improved to adapt to the expected compatibility problem.
Accordingly, there is a need for an improvement over existing hot plug interface connectors that overcomes the deficiencies described in the prior art.

Fig. 1 to 6 are schematic structural diagrams of a hot plug type interface connector 100 according to the present invention. The hot plug type interface connector 100 of the present invention comprises a cage body 1 and a connector 2 disposed in the cage body 1, wherein the cage body 1 is provided with a longitudinal socket 10 for accommodating a docking plug module (not shown), the connector 2 is disposed at the rear end of the socket 10, the connector 2 comprises an insulating body 21 and conductive terminals 22 fixed on the insulating body 21, the insulating body 21 is provided with a socket 211 recessed from front to back for plugging the docking plug module, the socket 211 is communicated with the socket 10 forward, the conductive terminals 22 are exposed in the socket 211 for electrically docking the contact 222 of the docking plug module, and the conductive terminals 22 comprise upper and lower rows of 22 contact 222. Thus, compared with the 20 contact portions 222 of the hot plug type interface connector 100 in the prior art, the two contact portions 222 of the conductive terminals 22 are added, so that the hot plug type interface connector 100 can provide more circuits along with the increase of the number of the conductive terminals 22 under the same volume; and the functions of 2 channels are added, and the functions of grounding, power supply, signals and the like can be performed according to the needs.
Preferably, each row of the conductive terminals 22 is provided with 11 contact portions 222. Namely, the upper and lower rows of contact portions 222, each row is provided with 11 contact portions 222, and thus, the size of the connector 2 in the left-right direction can be reduced as much as possible under the condition that the total amount of the contact portions 222 is controlled, which is advantageous for the trend of miniaturization of the connector 2.
As a further embodiment of the present invention, the connector 2 is provided with two upper and lower rows of conductive terminals 22, each row of 11 conductive terminals 22. That is, in this embodiment, each contact portion 222 corresponds to one conductive terminal 22, which is thus configured, and facilitates manufacturing and assembly. Of course, in other embodiments, the one conductive terminal 22 may also include more than one contact portion 222, i.e. share a portion of the conductive terminal 22, which may also implement the functions of the present invention.
In the present embodiment, the upper and lower rows of contact portions 222 are provided at intervals in the left-right direction. That is, as shown in fig. 4, the conductive terminals 22 adjacent to each other in the vertical direction are arranged at intervals in the horizontal direction, so that the strength problem of the whole insulating body 21 can be ensured, and the dimension of the connector 2 in the horizontal direction can be controlled to a large extent. In other embodiments, other arrangements may be provided.
In this embodiment, the insulating body 21 is further provided with terminal grooves 212 located on the upper and lower sides of the insertion groove 211 and communicating with the insertion groove 211 to accommodate the conductive terminals 22. In this way, the conductive terminal 22 is conveniently inserted and installed, and in other embodiments, the conductive terminal 22 may be embedded and formed on the insulating body 21.
The insulating body 21 is provided with a front surface 2101 and a rear surface 2102, the insertion groove 211 is recessed from the front surface 2101, the conductive terminal 22 comprises a main body 221 and a holding portion 223 extending transversely from the main body 221, and the holding portion 223 is inserted and held onto the insulating body 21 from the front and/or rear surface 2102. So arranged, the conductive terminals 22 can be firmly inserted onto the insulating body 21 through the holding portion 223, so that the assembly is convenient, and the size of the connector 2 in the front-rear direction can be reduced to a greater extent, which is more beneficial to the miniaturization trend of the connector 2.
Specifically, the main body 221 of the conductive terminal 22 is vertical, the contact portion 222 protrudes from the upper end of the main body 221 into the terminal slot 212, and the lower end of the main body 221 further extends with a welding portion 224. In this way, the main body 221 may be abutted against the insulating body 21, and the contact portion 222 may be disposed in the terminal slot 212 and exposed in the socket slot 211.
The welding parts 224 are provided in two rows at the front and rear lower ends of the front and rear surfaces 2102 of the insulating body 21. By means of the arrangement, the welding parts 224 are welded in two parts, and the problems of continuous welding and the like caused by too small interval between the welding parts 224 can be avoided.
The welded portion 224 extends in the horizontal direction. In this way, the soldering portion 224 may be soldered to a mounting circuit board (not shown).
