Description

Socket and communication system

The present invention relates to a socket and communication system.

When the connector is inserted into the socket, each contact of the connector is electrically connected to a corresponding contact in the socket. This allows for the transmission of electrical signals between the connector and the outlet. Typically, the socket uses the same set of contacts each time the connector is inserted, although in many systems, a given plug or socket of the system uses only a subset of the contacts in the set. Therefore, in order for the connector to work with the socket, the connector should be designed such that the set of contacts on the connector contacts the set of contacts on the socket. If connectors of different structural contact group types are inserted into the socket, each connector will not fit into the socket, or even if the connector is suitable, the connector contact set is not a suitable interface for the socket contact set. Therefore, the socket has strict restrictions on the type of connector it receives.

In view of the above problems, it is a primary object of the present invention to provide a socket capable of receiving different types of connectors.

Accordingly, in order to achieve the above object, a socket disclosed in the present invention, if the socket receives a type of connector, the connector contact engages with a group of socket contacts. If the socket receives another type of connector, the connector contacts engage the other set of socket contacts, which can be analogized for other types of connectors and other contact sets. Such a socket can also be referred to herein as a multi-purpose socket. When such a multi-purpose socket is configured for use with two different types of connectors, each associated with its own socket contact, the socket may also be referred to as a dual purpose socket. The connector-related connector detection mechanism detects which type of connector is plugged into the socket and communicates with the corresponding socket contact according to the given connector type. This allows the second connector to work with contact sets having different types of mechanical designs. For example, a contact set is used at high frequency, where considerations such as electrical impedance and crosstalk are primary.

The features and implementations of the present invention are described in detail below with reference to the drawings.

The embodiments described herein relate to sockets that receive different types of connectors. If one type of connector is received by the socket, then a set of socket contacts will be used to electrically connect the connectors. If another type of connector is received by the socket, another set of socket contacts will be used to electrically connect the connector, and so on.

The following describes a characteristic embodiment of a multi-purpose socket set for a plurality of connectors in accordance with "1A to 9". However, it will be apparent to those skilled in the art that, after reading this description, the principles of the present invention can be extended to any socket having multiple sets (two or more sets of contacts), wherein each set of contacts is used to connect different types of contacts Connector. For example, the dual-purpose socket shown in "1A" to "9th" is suitable for receiving two types of connectors. However, the principles described herein can be extended to other multi-purpose outlets that are adapted to receive three or more different types of connectors. In addition, the sockets shown in "1A" to "9" are suitable for receiving two different types of connectors: 1) laser cable (LASERWIRE) 10Gb/s active cable connector; and 2) TIA-968 The RJ-45 connector defined in the -A standard. However, the principles described herein are not limited to sockets that are capable of receiving a particular type of connector.

As a second citation, other types of connectors (here, laser cable connectors) are not known to the public when RJ-45 connectors are well known. Therefore, the laser cable connector will be described in detail in conjunction with "Fig. 10A" to "22D".

An exemplary multi-purpose socket will be described in conjunction with "1A to 9". "FIG. 1A" shows the component 100 of the socket seen from the top 100A direction. "1B" and "1C" are perspective views of the socket member 100 from the top 100B and the side 100C, respectively. In the present description, the front side of the socket relative to the socket means that it is close to the side of the socket into which the connector is inserted, and the rear side of the socket represents the side where the connector is inserted deeper into the socket. The top 〞 represents the connector side that engages the latch of the connector, while the bottom 〞 represents the side of the connector opposite the latch. This terminology will be used throughout this description except that the front and rear are reversed from "10A" to "22D" to more intuitively describe the laser cable connector.

Of course, component 100 is only a small fraction of all components of the socket. Here, only the printed circuit board 101 having the contact groups 102 and 103 mounted thereon is illustrated. Contact set 102 is used to engage the RJ-45 connector and contains a total of eight contacts. When the contact set 102 is bonded to the printed circuit board 101 at one end, the other end of the contact set 102 is unbound, allowing the contacts of the contact set 102 to bend slightly downward when the RJ-45 connector is inserted into the socket. . This is the same way as the conventional RJ-45 connector sockets engage the plug contacts. The contact set 103 is used to engage the laser cable connector described in the "Picture 10A" to "22D". Each of the contact sets 102 and 103 is electrically connected to a trace on the printed circuit board 101. Although the "Fig. 9" abstractly depicts the traces and is described in detail in conjunction with "Fig. 9", the traces are not shown in "1A" to "1C".

"2A" to "2C" are perspective views of the component 200 of the socket from the top front 200A, the side 200B, and the top rear 200C, respectively. In addition to the RJ-45 contact alignment fastener 201 and the laser cable contact main body 202, the components 200 shown in "2A" to "2C" are added to "1A" to " Element 100 shown in Figure 1C.

The RJ-45 contact alignment fastener 201 helps accommodate the RJ-45 contact set 102 in place and maintains proper spacing at each end of the contacts. Such contact alignment fasteners 201 can be found in a typical RJ-45 compatible socket, although in these typical RJ-45 connectors, the free ends of the contacts are typically along the rear surface of the socket opening (relative to the insertion) The groove in the direction of the pull is guided. The laser cable contact body 202 can be insert molded around the plug contacts, or a separate lead can be pressed into the plastic body and the free end on the 90 degree curved main printed circuit board surface to exit the desired direction and It is locked into the plastic body. However, the remaining portions of the contacts are still exposed to facilitate effective insert molding. The laser cable contact body 202 includes three projections 203A through 203C, each of which includes a contact group for contacting a corresponding contact group of the laser cable connector. As mentioned above, the combination of contact sets allows openings through which the electromagnetic radiation emitted by the body of the laser cable plug is minimized. Those skilled in the art, after reading this description, should understand that subdividing the laser cable contacts into three groups is not a necessary feature of the present invention.

"3A" to "3C" are perspective views of the component 300 of the socket from the top front 300A, the side 300B, and the top rear 300C, respectively. In addition to the RJ-45 contact holder 301 and the laser cable contact top cover/storage holder 302, the components 300 shown in "3A" to "3C" are added to "2A". The component 200 shown in "2C".

The RJ-45 contact holder 301 further helps to place the RJ-45 contact set 102 in a suitable position. In addition, the containment holder 302 can also be molded and bonded to the contact body 202. The housing holder 302 covers the previously exposed portion of the contact set 103. The housing holder 302 also includes a plurality of pins 311, 312, 313, and 314. Pins 311 through 314 help provide structural support for the receiving receptacle, as will be described below in conjunction with the drawings. In an example assembly, the RJ-45 contact set component can be made (pre-manufactured or better) before the RJ-45 contact set component is electrically connected to the printed circuit board 101. The contact set 102, contact alignment Fastener 201 and contact holder 301. It is to be noted that a single molded component can have the functions of the components 201 and 301 at the same time, and a single molded component can have the functions of the components 202 and 302 at the same time. Not shown in these figures, but element 202 or 302 or both elements simultaneously contain features that retain these elements with contact set 102 into all of the containment bodies. These features are similar to or have the same function as pins 311, 312, 313, and 314. Element 301 includes features, such as insulating rods, coupled to holes in the main printed circuit board to provide lateral alignment forces. The same rod may also have features that retain all of the components on the main printed circuit board, for example, by providing an active latch along the length separating rod and at the distal end of the rod extending along the far side of the motherboard to prevent structural movement and Provides stress relief for soldered contacts. Also, prior to the electrical connection of the laser cable contact set components to the printed circuit board 101, the laser cable contact set components can also be fabricated in advance to include the contact set 103, the contact body 202, and the containment holder 302.

"3D" and "3E" show another structure 300D and 300E of the contacts of the sockets of "3A" to "3C". That is, the precise structure of the contacts is not critical to the broader principles described herein, as long as the appropriate contacts are electrically contacted with the appropriate connectors when the connector is inserted into the socket.

Figure 4 shows a perspective view of the component 400 of the socket from the top of the top. The element 400 shown in "Fig. 4" is added to the element 300 shown in "3A" to "3C", and the socket shutter 401 is further illustrated. The socket baffle 401 can also be considered an element of the laser cable contact set component and thus can be secured to the component prior to its electrical connection to the printed circuit board. Alternatively, the socket baffle 401 can be bonded after the laser cable contact set components are bonded to the printed circuit board.

The socket shutter 401 is used as an element of the electromagnetic interference barrier between the main board and the surrounding environment, reducing coupling (usually high frequency) of electromagnetic radiation generated in the plug assembly or the main board to the external environment. In addition, the socket shutter 401 effects electromagnetic interference shielding of the laser cable when the laser cable connector is inserted into the socket. Thus, when the laser cable connector is inserted, the socket shutter 401 is used as an electromagnetic interference barrier between the laser cable connector and the motherboard and between the laser cable connector and the external environment.

The socket shutter 401 may be formed of a conductive material such as metal and includes a plurality of hands that are in electrical contact with the sleeve 1501 of the laser cable connector 1000 and the body of all of the socket assemblies when the connector 1000 is inserted into the socket. The socket shutter 401 extends to cover the front portion of the connector housing 1241 (described in "12A" to "12G") except for the areas of the openings 1211 to 1213. The small openings in these socket baffles are the largest openings in the connector and main electromagnetic interference barrier and limit electromagnetic interference better than a single large opening. At high frequencies, such as 5 GHz and above, the attenuation of the opening increases rapidly as the size of the opening becomes smaller relative to the wavelength of the radiation. The smaller opening is achieved by dividing the electrical contact into three groups of different spaces, which will be described below in conjunction with "12A" to "12E".

"5A", "5B" and "5C" are perspective views of the socket 500 from the top front 500A, the front 500B, and the rear 500C, respectively. The socket 500 is added to the element 400 shown in Fig. 4 and also shows the socket housing 501. The socket housing 501 includes holes corresponding to the pins 311 to 314. For example, holes 502 through 504 receive pins 312 through 314. There is another hole on the distal end side of the socket housing 501 for receiving the pin 311. Similar features can be added to retain the RJ-45 contacts. The receptacle housing 501 also includes apertures 505 and 506 to help latch the RJ-45 or laser cable plug connector in place.

"6A" to "6C" show the laser cable connector 1000 inserted into the socket 500 (described in conjunction with "10A" to "22D") from the top front 600A, the front 600B and the side. Perspective view of the 600C direction. In this state, the connector contact 1106 of the laser cable connector (refer to the contact 1106 of "11A" to "11E" and the corresponding description) contacts the contact group 103 on the socket side (such as " Figure 1A to Figure 1C show). This establishes an electrical connection between the connector 1000 and the outlet 500.

Additionally, the contact set 102 for the RJ-45 connector contacts the bottom side of the sleeve 1501 of the connector, causing the contact set 102 to bend downward. To prevent shorting of the contact set 102, the bottom side of the sleeve 1501 can be coated with an electrically insulating coating. Alternatively, contact set 102 can simply be retained to contact conductive sleeve 1501. The RJ-45-based Ethernet standard (most important 10BASE-T, 100BASE-TX, and 1000BASE-T) requires a circuit that is connected to the RJ-45 contact group to have an addressing short but does not damage any part of the main system circuit. Institutions. Thus, in the design of the socket 500 or connector 1000, shorting of the contact set 102 may not be a critical issue to avoid. However, to prevent short circuit problems, the sleeve 1501 or a portion of the laser cable connector of the laser cable connector can be coated with a mechanically strong insulating material if desired.

"Area 7A" and "FIG. 7B" are perspective views of a conventional RJ-45 connector plug 700 from the top front 700A and the rear 700B, respectively. The direction of the front 〞 and 〞 rear 命名 named above, which are named above, are reserved here. The connector 700 includes a cable housing 702 that is coupled to the connector end 701. The connector end 701 has a latch 703. Those skilled in the art familiar with the conventional RJ-45 connector can see from Figure 7B that the connector includes eight contacts 704 as defined in the standard TIA-968-A. RJ-45 connector 700 can represent any conventional RJ-45 connector.

"8A" to "8C" are perspective views of the RJ-45 connector 700 inserted into the connector 500 from the top front 800A, the front 800B, and the side 800C, respectively. In this state, the connector contact 704 contacts the contact set 102 of the receptacle 500 to electrically connect the RJ-45 connector 700 to the receptacle 500. And in this state, the latch 703 is engaged with the holes 505 and 506 of the connector housing 500 and the structure 507 which restricts the forward movement of the connector plug.

The RJ-45 connector cannot be inserted deep enough into the socket to contact other contact sets 103 of the laser cable connector. Structure 507 provides a mechanical barrier that prevents the RJ-45 connector from being inserted too deep into the socket. Structures 811 and 812 are used to prevent the tilting of the laser cable plug and provide additional support for the laser cable connector as it is inserted into the socket.

Fig. 9 is a schematic diagram showing the physical layer circuit 900 for controlling the operation of the socket. When the laser cable connector is inserted into the socket 500, the transmit or receive signal 911 can be transmitted from the laser cable physical layer 901 or to the laser cable physical layer 901. In this state, no signal passes between the RJ-45 physical layer 902 and the outlet 500. Switch 903 or other higher level circuitry is capable of detecting the presence of the laser cable connector and powering down the RJ-45 physical layer 902 to conserve energy. For example, a contact of a laser cable can be used to indicate detection. For example, perhaps the corresponding socket contacts are typically pulled high through a relatively high resistance (eg, 4.7 kOhms) and the corresponding plug contacts are grounded directly or pulled low with a small resistance (eg, 470 Ohms). The socket contacts therefore become high unless the laser cable connector is inserted. Switch 903 can use this signal directly or indirectly to detect the presence of a laser cable connector. If the presence of the laser cable connector is not detected, switch 903 controls the RJ-45 physical layer 902 to be energized and the laser cable physical layer 901 is powered down. This allows communication between the RJ-45 physical layer 902 and the outlet 500 through traces 912. Traces 911 and 912 in the figures are only symbolically illustrated and may be, for example, traces within printed circuit board 101. Physical layers 901 and 902 and switch 903 may be electrical circuits that are electrically connected to printed circuit board 101 and/or embedded within printed circuit board 101.

In general, it is necessary to have various magnetic components (transformers) in series and in parallel with RJ-45 contacts (minimum 4 components, but usually 8 or even 12). These components provide electrical isolation of common mode signals, including high DC voltages between systems. These components are often provided as discrete components (or multi-turn arrays), usually referred to as hybrid circuits on the motherboard. One potential use change of the present invention is to integrate these magnetic components within the connector body, as is conventional in RJ-45 sockets in Ethernet applications.

In one embodiment, the laser cable physical layer 901 is configured to operate at a data rate of 10 Gbps. On the other hand, the RJ-45 physical layer 902 is configured to operate at a typical RJ-45 speed, which may be a data rate of 10 Mbps, 100 Mbps, or 1000 Mbps. The multi-rate function of the RJ-45-based physical layer is very standard and is written to the relevant IEEE specifications for the 100Mb and 1000Mb standards. The RJ-45 physical layer can be a typical RJ-45 physical layer except that it responds to the power-up and power-down signals from switch 903.

Thus, the described socket and corresponding control mechanism allow the socket to operate with different types of connectors, with each type of connector using a different set of contacts within the socket. This allows the use of the socket to be expanded to provide more options in data rates and cables that use a single outlet.

An electrical connector into which a multi-purpose connector can be inserted is referred to herein as a 〞-laser cable 〞 connector. The structure of this connector will be described in conjunction with "Fig. 10" to "22D". The laser cable electrical connector has reduced electromagnetic interference (EMI) and is mechanically configured to match a suitable socket, as described above in connection with "1A" through "9th". The socket can be located on the main unit or on another external computer, machine or device. When the electrical connector is mechanically mated with a suitable receptacle, at least a portion of the electrical contacts of the electrical connector electrically contact at least a portion of the electrical contacts of the corresponding receptacle. But not limited to this application, the connector is also well suited for active optical cable use where the connector described herein is an external interface, but the actual data transfer is on a pair of optical fibers.

"10A", "10B" and "10C" are perspective views of the electrical connector 1000 representing one embodiment of the connector described herein from the top rear 1000A, the side 1000B, and the bottom 1000C, respectively. . The connector 1000 includes an insertion portion 1001 that can be inserted into the socket, and the latch 1002 can be mechanically engaged with the socket to lock the connector 1000 into the space within the socket until the latch 1002 is released next time. The latch 1002 engages the socket by simply pushing the insertion portion 1001 into the socket, causing the latch 1002 to bend downward as it engages the socket. Once the insertion portion 1001 of the connector 1000 is fully inserted into the socket, the configuration of the socket allows the latch 1002 to spring back into the mechanically locked position within the socket. By pressing down on the latch 1002, the latch 1002 disengages from the socket, allowing the latch 1002 to freely move out of the socket again.

In the present description, the front side of the connector relative to the connector means one side of the electrical interface of the connector of the inserted portion, and the rear side of the port means the side of the connector close to the cable. The top side of the crucible represents one side of the connector containing the latch, and the side of the bottom side of the crucible represents the side of the connector opposite the latch. When referring to a view of a connector or connector, the term remains the same throughout the appendix, even if other components (such as a main socket and/or adapter) appear in the view.

First, the detailed structure of the connector 1000 will be described in conjunction with "11A" to "22D". Various methods for terminating optical fibers in active optical cable implementations will then be described.

First, the connector structure will be described. Upon describing a particular connector, those skilled in the art will appreciate upon reading this description that the design principles of the connectors applied to the present description can be widely used to reduce electromagnetic interference of various electrical connectors.

Figure 11A shows a perspective view of several internal components 1100 of the active optical cable using the electrical connector of the present invention from the top front 1100A. "11B", "11C", "11D" and "11E" are the internal components 1100 of the electrical connector 1000 from "10A" to "10C" respectively from the top rear A perspective view of 1100B, side 1100C, front 1100D, and bottom 1100E. In this step structure, the optical fiber pattern is not shown. Only some of the connectors themselves are shown.

The internal component 1100 includes a printed circuit board 1103 having an integrated circuit 1104 mounted thereon. The integrated circuit 1104 can have any circuitry on which it is useful or advantageous to turn the electrical signal into an optical signal or inverse transform. For example, integrated circuit 1104 includes a laser driver, a post amplifier, a limiting amplifier, a reverse impedance amplifier, a controller, or other desired circuitry. The printed circuit board 1103 and the transmitting optical sub-device (TOSA) 1101 perform electrical signal communication, and the latter finally operates to convert the electrical signals into transmission optical fibers ("11A" to "11E"), but subsequent The optical transmission signal is shown in some of the figures. The receiving optical sub-device (ROSA) 1102 will eventually operate to convert the optical signal received from the receiving optical fiber (not shown) into an electrical signal. The printed circuit board 1103 transmits these electrical signals to the integrated circuit 1104. The electrical signal is communicated between the printed circuit board 1103 and the electrical contacts 1106 in the electrical interface device 1105. These electrical contacts 1106 will form a mechanical or electrical interface with the socket when the connector is inserted into the socket. Although "11A" through "11E" illustrate the transmitting optical sub-device 1101, the receiving optical sub-device 1102, and the printed circuit board 1103, these elements are not the main elements in accordance with the broadest principles described herein. For example, a connector without a printed circuit board can be fabricated, and the transmitting optical sub-device and the receiving optical sub-device can be integrated into an integrated circuit package.

In one embodiment, a light emitting diode (LED) 1107 is attached to the bottom side of the printed circuit board 1103, as seen in "11C" and "11E". Light-emitting diode 1107 can be used as a light source to communicate status information to the user. Finally, as can be seen from the subsequent figures, the light-emitting diode 1107 directs light through an optical light guide (described below) to emit visible light to the outside of the connector. Through this mechanism, users can see status information.

The interface device 1105 will be further described in conjunction with "FIG. 12A" and "FIG. 12E", wherein the figures illustrate various components of the electrical interface device 1105 from various perspective and structural stages. The interface device 1105 can be fabricated prior to assembly of the connector 1000.

As shown in "Fig. 12A", the electrical contacts 1106 are divided into groups. For example, an electrical contact includes a contact group 1201 having a total of four contacts (contacts 1201A, 1201B, 1201C, and 1201D), and a contact group having a total of four contacts (contacts 1202A, 1202B, 1202C, and 1202D) 1202 and a contact group 1203 having a total of four contacts (contacts 1203A, 1203B, 1203C, and 1203D). In subsequent figures, individual contacts may sometimes not be labeled to prevent the drawings from being unnecessarily complicated. However, contact groups are more commonly labeled. Each contact group 1201 to 1203 is separated from other groups by a certain distance. For example, there is a large spacing between contacts 1201D and 1203A and between contacts 1203D and 1202A.

In one embodiment, the contact group 1201 can be used to communicate differential electrical transmission signals (sometimes referred to in the art as TX+ and TX-signals) and includes two ground signals for improved signal quality. For example, contacts 1201A and 1201D can be ground contacts, while contacts 1201B and 1201C are TX+ and TX- contacts that actually carry differential electrical transmission signals during operation. By controlling the distance between the differential transmission contacts 1201B and 1201C and the distance between each differential transmission contact and the adjacent ground contact 1201A or 1201D, the common mode impedance and differential mode impedance of the electrical transmission signal are more Easy to control.

Contact group 1202 can be used to communicate differential electrical receive signals (sometimes with RX+ and RX-signals) and includes two ground signals for improved signal quality. For example, contacts 1202A and 1202D can be ground contacts, while contacts 1202B and 1202C can be RX+ and RX- contacts that actually carry differential electrical receive signals during operation. Moreover, by controlling the distance between the differential receiving contacts 1202B and 1202C and the distance between each differential receiving contact and the adjacent grounding contact 1202A or 1202D, it is easier to control the common mode impedance of the electrical receiving signal and Differential mode impedance. This common mode and differential mode impedance control is used to reduce signal degradation caused by contacts, which is especially important at high data rates.

It should be noted that each of the ground contacts 1201A, 1201D, 1202A, and 1202D has a respective cylinder 1204A, 1204B, 1204C, and 1204D. The post can be inserted into an existing ground hole in the printed circuit board 1103 to allow for the grounding of the ground contact to be fixed. In addition, a more robust mechanical connection between the interface device 1105 and the printed circuit board 1103 is allowed, thereby potentially improving stability. Fix the grounding contact post in the corresponding grounding hole of the printed circuit board. See "Figure 11B" for better. However, for the broader principles described herein, the cylinder is not primary.

Contact group 1203 can have contacts other than those that actually carry high speed electrical signals. For example, the contact 1203 can be used to activate the integrated circuit 1104 and the light-emitting diode 1107, which can carry the far-end energy for providing energy through the cable itself (if a conductor is also present in the cable), and can be used for a low-speed serial interface (one wire) Or two) or have other desired uses. One of the contact groups 1203 can be used to implement the function of detecting the presence of the connector. For example, one of the contacts can be grounded and the corresponding contact in the socket is pulled high. If the connector is plugged into the socket, then the socket contacts will be pulled low, allowing the socket and any connected host to recognize the presence of the connector.

"FIG. 12B" shows a perspective view of the component 1220 of the interface device 1105 from the top rear. Element 1220 includes contact groups 1201, 1202, and 1203 that are over-molded by body 1221. "FIG. 12C" shows a perspective view of the component 1220 from the rear of the bottom. In order to control the impedance of the various contacts, the contacts within the body 1221 can have various forms. The body 1221 can be an insulating material to prevent shorting of various contacts. The main body 1221 includes various inclined protrusions 1222A to 1222D to allow the insulating housing to be mechanically interlocked with the main body 1221, which will be described later in connection with "12D to 12G".

In particular, "12D" and "12E" are perspective views of the interface device 1105 from the top rear and the bottom rear, respectively, which add the housing 1241 to "12B" and "12C". Element 1220. The housing 1241 can be slid from the front to the elements 1220 of "Fig. 12B" and "12C", such that the inclined projections 1222A to 1222D of the main body 1221 are engaged with the holes 1242A to 1242D of the housing 1241, respectively. The receiving body 1241 is formed of an electrically insulating material such as plastic.

"12F" and "12G" are perspective views of the interface device 1105 from the front and the side, respectively. In this case, however, the container 1241 is in a transparent form. As is apparent from "FIG. 12F", each of the electrical contacts 1201A to 1201D, 1202A to 1202D, and 1203A to 1203D extends through the main body 1221 and the respective holes 1261A to 1261D, 1262A to 1262D, and 1263A to 1263D of the housing. As is apparent from the "12G" diagram, each contact (e.g., electrical contact 1201A) has some clearance to move upwardly when contacting the electrical connector of the socket without contacting the housing 1241.

As described above, the mounted interface device 1105 is adhered to the printed circuit board 1103 to form the elements 1100 of "11A" to "11E".

FIGS. 13A to 13F are perspective views of the component 1300 of the connector 1000 from the top front 1300A, the top rear 1300B, the side 1300C, the top 1300D, the bottom 1300E, and the rear 1300F, respectively. Inserting the narrow cylindrical insertion portion of the transmitting optical sub-assembly 1101 into the hole 1311 of the plug chassis 1301, and inserting the narrow cylindrical insertion portion of the receiving optical sub-device 1102 into the hole 1312 of the plug chassis 1301, "13A The element 1300 of the "FIG. 13F" is added to the element 1100 shown in "11A" to "11E". The plug chassis 1301 is mechanically coupled to the transmitting optical sub-assembly 1101 and the receiving optical sub-assembly 1102. At this stage, the plug chassis 1301 can still slide relative to the transmitting optical sub-assembly 1101 and the receiving optical sub-assembly 1102. However, in a subsequent assembly step, the plug chassis 1301 is fixed. The plug chassis 1301 has a channel region 1302, and the light guide is located within the channel region 1302 and is flush with the upper surface of the plug chassis 1301. The plug chassis 1301 also has other features, the function of which will appear in the following description, which includes a cable insertion portion 1313 having a slot 1314 formed therein. In one embodiment, the plug chassis 1301 is used as an electromagnetic interference barrier to the rear end of the connector. The plug chassis 1301 may be a die-casting mold, which may be metal or plastic soaked with metal such as zinc or copper.

"FIG. 14A" and "FIG. 14B" are perspective views of the component 1400 of the connector 1000 from the top front 1400A and the bottom front 1400B, respectively. By adding the optical light guide 1401, the elements 1400 shown in "Fig. 14A" and "Fig. 14B" are added to the elements 1300 of "Fig. 13A" to "Fig. 13F". A portion 1404 of the optical light guide 1401 passes through a hole 1402 in the printed circuit board 1103 to be optically coupled to the light emitting diode 1107. The optical light guide 1401 is placed in position through the channel 1302 placed into the plug chassis 1301. If the light-emitting diode 1107 emits light, at least a portion of the light passes through the optical light guide 1401 and is illuminated to the outside of the connector by the outer portion 1403 of the optical light guide 1401.

"15A" and "15B" are perspective views of the component 1500 of the connector 1000 from the top front 1500A and the bottom front 1500B, respectively. The components 1500 of "Fig. 15A" and "Fig. 15B" are added to "Fig. 14A" and "Fig. 14B" by sliding the integrated sleeve 1501 on the front of the connector to press fit with the plug chassis 1301. Element 1400. This mechanically secures some of the connectors in place. The integrated sleeve 1501 is also used as an electromagnetic interference barrier. In one embodiment, the sleeve is formed of metal, but any other electromagnetic interference barrier material is also possible. Thus, the sleeve is combined with the plug chassis 1301 for use as an electromagnetic interference barrier for the connector, with the exception of the front end of the connector. In the following description, a more complete electromagnetic interference protection will be provided when the connector is inserted into the socket. As described below, when the connector is inserted, the socket baffle on the side of the socket at the rear of the socket provides electromagnetic interference protection in front of the connector. Therefore, in this inserted state, the connector is surrounded by the electromagnetic interference shield except for a few holes thereon.

In particular, the only holes in the electromagnetic interference barrier are: 1) in front of the connector, 2) a small opening for transmitting optical sub-device 1101 and receiving optical sub-assembly 1102, through which optical fibers and sockets pass, and 3) small holes, The optical light guide 1401 passes through it to transmit light emitted inside the electromagnetic interference barrier to the outside of the electromagnetic interference barrier. As described above, when the plug is inserted, the electromagnetic interference barrier is realized by the socket shutter in the socket. All of these holes are small, thus allowing a small passage of electromagnetic interference signals from the connector. Therefore, the electromagnetic interference barrier improves the signal quality of the high-speed electrical signals and other signals appearing in the connector. This also prevents high frequency signals generated within the connector from interfering with other devices external to the connector.

"16A" to "16C" are perspective views of the element 1600 of the connector 1000 from the bottom 1600A, the rear 1600B, and the side 1600C, respectively. The element 1600 shown in "16A" to "16C" is added to the element 1500 of "Fig. 15A" and "Fig. 15B", in which the optical cable 1601 is added. The optical cable 1601 includes a transmission optical fiber 1611 that passes through the cable insertion portion 1313 of the plug chassis 1301. The corresponding core 1621 is optically coupled to the transmitting optical sub-device 1101. The manner of connection will be explained below in conjunction with "17th through" to "19D". Optical cable 1601 also includes receiving optical fibers 1612 that pass through cable insertion portion 1313 of plug chassis 1301. The corresponding core 1622 is optically coupled to the receiving optical sub-assembly 1102. The manner of connection will be explained below in conjunction with "17th through" to "19D". The post 1630 allows the tie rods within the cable 1601 to be bent and secured to the post 1630 to prevent the cable 1601 from being displaced from the connector. However, various crimping mechanisms can be used for this purpose.

For standard LC type terminals, an LC ferrule can be used to optically connect each fiber to its respective transmitting optical sub-device and receiving optical sub-assembly. For example, "Fig. 17" shows a bottom perspective view of the component 1700 of the connector, which is added to the component 1600 of "16A" to "16C", wherein the ferrules 1731 and 1732 are used to assist in fiber connection. Each of the transmitting optical sub-devices and the receiving optical sub-devices.

"18A" and "18B" are perspective views of the component 1800 of the connector from the bottom 1800A and the bottom rear 1800B, respectively. The elements 1800 shown in "Fig. 18A" and "Fig. 18B" are added to the element 1700 of "Fig. 17", in which the socket sockets 1801 and 1802 are added to assist the lower sockets 1731 and 1732 in transmitting the optical sub-objects, respectively. The device and the receiving optical sub-device are held in position. In the actual assembly, the states shown in "16A" to "16C" do not actually exist. And sometimes each core can be properly terminated. For example, to terminate each fiber, a suitable ferrule is attached to the end of the fiber and the socket ferrule on the fiber. The socket is then inserted into a suitable transmitting optical sub-device or receiving optical sub-device.

"19A" to "19D" are perspective views of the component 1900 of the connector from the side 1900A, the bottom 1900B, the bottom rear 1900C, and the rear 1900D, respectively. The elements 1900 shown in "19A" to "19D" are added to the element 1800 shown in "Fig. 18A" and "Fig. 18B", wherein the ferrule spring clip 1901 is in position to the socket base. 1801 and 1802 provide forward force. Thus, the socket sockets 1801 and 1802 are capable of gripping the ferrules at appropriate locations within the transmitting optical sub-device and the receiving optical sub-device, respectively. The socket socket (and therefore the corresponding socket) is limited in rotation due to its hexagonal shape and one of which is very close to the plug chassis. The hexagonal shape also allows for a larger support surface between the socket spring clips 1901 on the socket sockets 1801 and 1802.

Fig. 20 is a bottom perspective view of the element 2000, which is added to the element 1900 shown in "19A" to "19D" except that the bushing 2001 is in position. The bushing 2001 includes an insertion portion 2003 that is inserted into the slot 1314 of the plug chassis 1301. The sleeve also includes a flange 2002 that abuts the cable insertion portion 1313 of the plug chassis 1301 when the insertion portion 2003 is inserted into the slot 1314.

Fig. 21 is a bottom perspective view of the component 2100, which is added to the component 2000 shown in Fig. 20, in which the strain relief cartridge 2101 is pulled close to the flange 2002 to compress and adapt to the surrounding bushing 2001 ( In the "21st picture", it is located below the strain relief cylinder 2101). Both the bushing 2001 and the strain relief barrel 2101 are located on the cable 1601 before the fibers in the transmitting optical sub-assembly and the receiving optical sub-assembly terminate. In this manner, the bushing 2001 and the strain relief cartridge 2101 need only be guided by the cable 1601 to be pulled forward to be in the proper position.

"22A" to "22D" are perspective views of the connector 2200 from the bottom perspective 2200A, the side 2200B, the bottom 2200C, and the top rear 2200D, respectively. The element 2200 shown in "22A" to "22D" is added to the element 2100 shown in Fig. 21, in which the rear cover 2201 is slid upward from the cable and is positioned to provide appropriate access to the plug chassis 1301. cover. The rear cover 2201 includes a latch 2202 having a partial clearance to press downward toward the plug chassis.

From "10A" to "10C", the final step in assembly of the connector 1000 is to slide the latch 1002 above the front of the connector. The latch 1002 interlocks with the latch 2202 of the rear cover 2201 to snap into place to complete the connector assembly. Portions of the internal components of the connector can be disassembled by simply releasing the latch 2202, removing the latch 1002, and sliding the rear cover 2201 rearward.

Thus, embodiments of the connector that have been described allow for reduced electromagnetic interference emissions of electromagnetic radiation emitted within the connector.

The connectors shown in "Picture 10A" to "22D" include terminals for optical fibers using a ferrule such as an LC ferrule. Such a terminal can be realized, for example, using glass fibers. However, the principles of the present invention can also be extended to connectors in which plastic fibers are used and the plastic fibers are terminated.

When the fiber is glass or plastic, the termination can be accomplished using different methods. For example, the cable can simply be cut to the correct length and the cable protection layer removed from the extreme end of the cable to expose the optical fibers. The fibers are then cut neatly in a direction perpendicular to the length of the cable. The fibers can then be inserted directly into the holes 1311 and 1312 of the plug chassis 1301. In the present embodiment, the diameters of the holes 1311 and 1312 are different, as shown in "Fig. 13A" to "Fig. 13F", indicating that the diameters between the bare fibers and the ferrule are different. In addition, in addition to the ferrule spring clip 1901, some other mechanisms can be used to provide forward biasing of the fibers to mechanically secure the fibers into the appropriate openings of the transmitting optical sub-device or receiving optical sub-assembly. This termination can be done on site or at the time of cable manufacturing.

In the illustrated embodiment, the fiber termination can occur through the exterior of the electromagnetic interference barrier (defined by the rear plug chassis 1301, the front housing 1241 and the sleeve 1501 between). However, the terminated fibers are inserted through the apertures into the electromagnetic interference barrier. Therefore, the design of the fiber termination mechanism can be independent of the design of the electromagnetic interference barrier. Further, as described above, the fiber end mechanism is very easy to access by first removing the latch 1002 mechanism and then removing the back cover 2201. This will expose the fibers, allowing the fiber ends to be properly disassembled if desired, or allowing for easy displacement of the connector itself.

Such a dual purpose socket has significant advantages. Many devices that require a network or other electrical connection have physical limitations that do not have enough space for a desired or ideal electrical outlet. This problem is particularly acute when considering a large number of ideal residual connections. In many devices, such as lightweight notebook computers, the number of electrical connectors actually increases the size of the overall design. Again, this limitation limits the different types of connections supported in lightweight devices and leads to undesirable tradeoffs when trying to support new connection types.

Other very important applications are network switches or routers. This dual purpose socket maximizes the number of connections within a given chassis size. For example, for Ethernet devices, 48 RJ-45 ports are typically supported in a standard 1U rack space for connections up to 1 Gb/s per 埠. If a new type of connector is required, such as a 10 Gb/s connection, then the manufacturer must provide a different chassis of each type of 48 turns, or some combination of 1 and 10 G turns, one type or other type that is significantly less than 48 turns.

The dual purpose connectors described herein address their correlations. Allowing systems already in use for 1G RJ-45 connection space (ie, notebooks, servers, or other devices) to contain, for example, 10G ports. Also, 48 turns of 1G and 10G connections within a 1U switch (with 48 ports that can be used simultaneously) are allowed.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention. Please refer to the attached patent application for the scope of protection defined by the present invention.
