Description
Technical Field
[0001] The present invention relates to the field of connectors, and particularly to an Ethernet separable quick plug - and - play electrical connector. Background Art
[0002] With the advent of the information age, signal transmission or reception is required all the time in life. To obtain reliable and stable signals, it is necessary to reduce signal attenuation or electromagnetic interference, which poses increasingly high requirements for electrical connectors. Along with the development trend of miniaturization and high density of electrical connectors, high requirements are put forward for quick plug - and - play of electrical connectors, connection between the housing and cable shielding, and sealing between the cable and the housing. Currently, most electrical connectors for Ethernet or signal transmission are threaded electrical connectors. When multiple threaded electrical connectors need to be densely arranged on the same panel, their disadvantages of difficult mating or locking are particularly prominent; there are also few options for forced anti - misoperation between electrical connectors; modular, cold - crimping, and detachable highly reversible structures are particularly favored by the market. Existing electrical connectors are difficult to meet these demanding conditions simultaneously. Therefore, it is necessary to design a modular cold - crimping quick plug - and - play electrical connector with good shielding effect, good sealing performance, and convenient operation.

[0018] The connector housing part is arranged with double key positions or multiple key positions (for forced anti-misoperation of electrical connectors for different uses). Its main functions are connection (mechanical connection and electrical connection) and separation with the mating end, as well as connection or fixation of various components (modules) of the connector itself, making each part an integral whole; the contact part adopts a pin-hole structure (not limited to the pin-hole structure), mainly for connection with the cable (using cold crimping) and connection with the hole positions of the mating end; the main function of the spring part is to provide an auxiliary reset force for the housing part after the electrical connector is separated, so as to improve the service life of the electrical connector; the main function of the insulating part is to position and install the contact member and insulate the contact member from the outer housing; the main function of the shielding part is to make a 360-degree connection between the cable shielding layer and the electrical connector housing; the main function of the sealing part is to connect, seal and fix the connector and the cable, and combine the connector with the external material (cable) into an integral whole.
[0019] A modular cold crimping plug-and-play electrical connector includes a socket, and the socket includes a housing assembly (3-1) and a contact body assembly (3-2) arranged in the housing assembly (3-1).

A first shielding spring (3-4) is arranged in the housing assembly (3-1), and a protruding locking platform (3-5) is arranged on the inner end of the housing assembly (3-1) that is mated with the plug.
[0020] In the above technical solution, grooves are arranged along the circumferential direction on the inner wall of the housing assembly (3-1), and the grooves are used to arrange the shielding spring (3-4).
[0021] In the above technical solution, the shielding spring (3-4) and the housing assembly (3-1) can be separated from each other, and the two are independent structures.
[0022] In the above technical solution, the inner end port of the housing assembly (3-1) that is mated with the plug is set as an inclined surface (3-6).
[0023] In the above technical solution, a concave annular groove is arranged on the inner wall of the housing assembly (3-1) along the direction of mating with the plug.

[0025] In the above technical solution, the contact body assembly (3-2) includes an insulator and pins and ground pins (3-7) provided on the insulator.
[0026] In the above technical solution, the ground pin (3-7) is fixedly provided on the insulator. One end of the ground pin (3-7) is used for welding with the wire core, and the other end contacts the inner wall of the housing assembly (3-1) through elastic force.
[0027] In the above technical solution, the ground pin (3-7) includes an elastic long arm (3-71). One end of the long arm (3-71) is a contact point (3-74), and the other end of the long arm (3-71) is a grounding point (3-75) for welding with the wire core after passing through a fixing part (3-72) and a positioning part (3-73).
[0028] In the above technical solution, the fixing part (3-72) and the positioning part (3-73) are fixedly connected to the insulator, and the contact point (3-74) contacts the inner wall of the housing assembly through the elasticity of the long arm (3-71).
[0029] The outer shell of this electrical connector is a metal housing, which uses double-key or multi-key positioning (with forced anti-misalignment) with the mating end, adopts inclined plane guidance, and adds a shielding spring between the housings to make the socket housing and the mating housing in close contact. The shielding spring is made of a highly elastic material and is squeezed between the housings, enabling the outer shell, the shielding spring, and the mating outer shell to be connected or shielded omnidirectionally and continuously at 360 degrees, thus avoiding the phenomenon of momentary interruption in rigid contact of the outer shell. At the same time, an anti-misalignment module is also added to the socket housing. This anti-misalignment module is of a post-loading type, and different colors are used to distinguish the same electrical connectors with different uses in the same area.
[0030] The housing assembly (which can be installed separately) and the contact body assembly (which can be installed separately) can be separately installed and then integrally installed with the equipment. The contact body assembly is installed through a guiding inclined plane, and the outer shell assembly contacts the elastic cantilever of the ground pin.
[0031] A modular cold-press pluggable electrical connector includes a wire core assembly. The wire core assembly sequentially includes a locking sleeve (1-1), a shielding sleeve (1-2), a support sleeve (1-3), an outer insulating sleeve (1-4), and an inner insulator (1-5) from the wire core end to the connection end. Cold-press connections are used between adjacent components, and a second shielding spring (1-2) is provided between the locking sleeve (1-1) and the support sleeve (1-3).
[0032] In the above technical solution, the inner insulator (1-5) includes a card slot (1-51) and a cantilever beam (1-53). A pin (1-52) is press-fitted into the card slot (1-51), and one end of the pin (1-52) is used for welding with the wire core (1-7).
[0033] In the above technical solution, the cantilever beam arm (1-53) is arranged on the end side of the inner insulator (1-5) and is used to be buckled with the outer insulating sleeve (1-4).
[0034] In the above technical solution, a concealed buckle (1-41) is provided on one end of the outer insulating sleeve (1-4), and the concealed buckle (1-41) and the cantilever beam arm (1-53) on the inner insulator (1-5) are matched and engaged with each other.
[0035] In the above technical solution, a connecting arm (1-42) is provided on the end of the outer insulating sleeve (1-4), and the connecting arm (1-42) is connected to the end of the supporting sleeve (1-3) through interference contact.
[0036] In the above technical solution, after the support sleeve (1-3) is connected to the outer insulating sleeve (1-4), the end of the support sleeve (1-3) abuts against the buckle (1-41) and the buckle of the cantilever beam arm (1-53).
[0037] In the above technical solution, the outer diameter of the connecting arm (1-42) is smaller than the outer diameter of the outer insulator sleeve (1-4), and the connecting arm (1-42) is a flexible connecting end.
[0038] In the above technical solution, an inner step is provided in the port on the support sleeve (1-3) that is butt-jointed with the locking sleeve (1-1), and the second shielding spring (1-2) is provided on the inner step.
[0039] In the above technical solution, an annular groove is formed between the inner step and the end face of the locking sleeve (1-1), the second shielding spring (1-2) is arranged in the annular groove, and the second shielding spring (1-2) is squeezed by the connection of the locking sleeve (1-1) relative to the support sleeve.
[0040] In the above technical solution, the locking sleeve (1-1), the shielding sleeve (1-2), the supporting sleeve (1-3) and the outer insulating sleeve (1-4) are respectively provided with positioning keys and slots, and the two adjacent connected components are matched and snap-fitted by cold pressing to achieve the keys and slots.
[0041] For the wire core cold pressing connection component of the present invention, the pin is inserted into the slot of the inner insulating part, the outer insulating sleeve is put on after aligning the key positions (uniqueness, for forced anti-misoperation), and the inner insulating part and the contact part are fixed by the snap fasteners of the outer insulating part; the assembled whole is connected to the support sleeve, and is tightly fitted with the inner wall of the support sleeve through the opening key positions and the outer insulating connection arms, so that it becomes an integral whole (without external force, it will not become loose, and the opening key ensures the uniqueness of the installation direction), and the end face of the support sleeve and the cantilever of the inner insulating part limit the axial movement of the inner insulating part; the cable shielding is connected and the wire is preliminarily locked through the shielding spring (360-degree direction); then, the ribs on the circumferential direction of the locking sleeve are tightly fitted with the inner wall of the support sleeve, and the shielding spring is compressed by the inclined plane to lock the cable and enhance the shielding density. In this way, a modular cold pressing integral installation structure is formed, and the disassembly and reverse operation can be carried out in the reverse of the above installation principle.
[0042] An electric connector shielding and sealing structure includes, from one end to the other end, a support sleeve (1-3) connected inside a housing body (4-1), a locking sleeve (1-1) connected to the support sleeve (1-3), a sealing sleeve (4-4) connected inside the locking sleeve (1-1), and a locking nut (4-5) connected to the locking sleeve (1-1) and the housing body (4-1) in sequence through threads. A second shielding spring (1-2) is arranged inside the support sleeve (1-3).
[0043] In the above technical solution, the locking sleeve (1-1) is inserted into the support sleeve (1-3), and the second shielding spring (1-2) is arranged between the locking sleeve (1-1) and the support sleeve (1-3).
[0044] In the above technical solution, an inwardly sunken step is arranged on the inner side of the support sleeve (1-3). An annular groove is formed between the end face of the locking sleeve (1-1) after being inserted into the support sleeve (1-3) and the step, and the second shielding spring (1-2) is arranged in the annular groove.
[0045] In the above technical solution, the second shielding spring (1-2) is arranged in the annular groove, and the locking sleeve (1-1) squeezes the second shielding spring (1-2) along the connection direction, and the second shielding spring (1-2) contracts towards the center.
[0046] In the above technical solution, a step is arranged inside the housing body (4-1), and the support sleeve (1-3) and the locking sleeve (1-1) are inserted onto the step inside the housing body (4-1) after being connected.
[0047] In the above technical solution, the outer side of the locking sleeve (1-1) includes a threaded section connected to the locking nut (4-5) and a sealing section connected to the housing body (4-1). The outer diameter of the threaded section is larger than that of the sealing section, and a sealing ring (4-2) is arranged between the sealing section and the housing body (4-1).
[0048] In the above technical solution, the outer diameter of the outer housing (4-1) is smaller than the inner diameter of the lock nut (4-5), and a thread is provided on the outer side surface of the outer housing (4-1).
[0049] In the above technical solution, after the outer housing (4-1) is connected to the sealing section of the lock sleeve (1-1), the outer side surface of the outer housing (4-1) is flush with the outer side surface of the threaded section of the lock sleeve (1-1).
[0050] In the above technical solution, the lock nut (4-5) is sequentially connected to the threaded section of the lock sleeve (1-1) and the outer housing (4-1) through a threaded connection.
[0051] In the above technical solution, the sealing sleeve (1-1) is a flexible sleeve and is inserted into the sealing sleeve by extrusion cold press fitting.
[0052] The shielding layer of the cable passes through the ring spring (360-degree closed for 360-degree shielding). By driving the lock sleeve with the lock nut to compress the shielding spring, the shielding spring contracts (increasing the shielding density) and closely fits with the cable shielding; the compressed shielding spring closely fits with the support sleeve, and the support sleeve closely fits with the connector housing.
[0053] The outer rubber layer of the cable passes through the sealing sleeve (360-degree closed). By driving the lock sleeve with the lock nut to compress the sealing sleeve, the sealing sleeve closely fits with the outer rubber of the cable, achieving the sealing of the cable and the electrical connector; the space between the electrical connector housing and the lock sleeve is sealed through a sealing ring (a shrinkable substance made of a rubber material outside the sealing ring), achieving the overall sealing of the tail of the connector.
[0054] Pass the processed cable through the lock sleeve (the lock sleeve installed with the sealing sleeve and the sealing ring), the shielding spring and the support sleeve in sequence, and then press the lock sleeve into the support sleeve with a little force through the installed keyway, so that the cable and the sealing and shielding function module in the following figure become an integral whole, and then install it into the connector housing.
[0055] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:
[0056] All connectors of the present invention adopt a cold press fitting connection structure and achieve connection through the axial plugging of the connector, avoiding the way of rotating and tightening with force, especially for installation in special environments, especially in dense installation environments.
[0057] The present invention uses the cold press fitting method for connection, which can avoid the loosening that may occur in the traditional rotating tightening in a vibrating environment. As long as it is not affected by external forces, the cold press fitting will not fall off.
[0058] The cold pressing connection of the present invention is very convenient for actual on-site assembly and connection. During assembly, it can avoid the use of special tools required for traditional rotary tightening, and the cold pressing connection operation can be achieved through manual operation.

Specific embodiments
[0073] All features disclosed in this specification, or all steps in any disclosed method or process, except for mutually exclusive features and / or steps, may be combined in any manner.
[0074] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically recited, may be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically recited, each feature is merely an example of a series of equivalent or similar features.
[0075] This embodiment is a separable quick-disconnect electrical connector for Ethernet signal transmission, including three parts: a plug, a socket, and a cold crimping structure for the wire core, and there is an improvement in the structure for shielding and sealing during the process of the wire core contacting the connector.
[0076] Such as Figure 12As shown in the figure, it is a schematic diagram of the shielding and sealing structure of this embodiment. The structure for shielding and sealing the cable mainly includes a support sleeve 1-3, a shielding spring 1-2, a locking sleeve 1-1, and a sealing sleeve 4-4. One end of the support sleeve 1-3 is provided with a sunken step. One end of the locking sleeve 1-1 is inserted onto the sunken step of the support sleeve 1-3. There is a gap between the locking sleeve 1-1 and the sunken step of the support sleeve 1-3. A shielding spring 1-2 is arranged in this gap. The shielding spring 1-2 is a 360-degree angularly closed ring spring, and the shielding spring 1-2 is squeezed between the locking sleeve 1-1 and the step of the support sleeve 1-3. There is also a sunken step arranged inside the other end of the locking sleeve 1-1. This sunken step is used to connect the sealing sleeve 4-4. The sealing sleeve 4-4 in this embodiment is a flexible plastic sleeve, while other components are rigid components, and it is nested inside the locking sleeve 1-1 by extrusion. Threads are arranged on the outer side surface of the locking sleeve 1-1, and the threads are used to connect the locking nut 4-5.
[0077] As Figure 11 shown, in this embodiment, the wire core to be shielded and sealed needs to be fixed. Therefore, the assembled support sleeve 1-3 is arranged inside the outer housing 4-1. Threads are arranged on the outer side surface of the outer housing 4-1. The locking nut 4-5 is threadedly connected to the locking sleeve 1-1 from the direction of the locking sleeve 1-1 at the opposite end of the support sleeve and then threadedly connected to the outer housing 4-1. In order to ensure the sealing performance of the outer housing 4-1, a sealing ring 4-2 is arranged between the outer housing 4-1 and the locking sleeve 1-1. In order to ensure the fixed position of the sealing ring 4-2, a sealing groove is arranged on the outer side surface of the locking sleeve 1-1, and the sealing ring 4-2 is arranged in the sealing groove; the entire sealing ring 4-2 is sleeved on the locking sleeve 1-1.
[0078] The wire core 1-7 passes through the locking sleeve 1-1, the shielding spring 1-2, and the support sleeve 1-3 and is fixedly connected. Conductive tape is wound around the surface of the wire core 1-7 corresponding to the shielding spring 1-2. When the locking sleeve 1-1 is squeezed towards the support sleeve 1-3, the shielding spring 1-2 is squeezed and contracts towards the center of the circle. After being compressed, the shielding spring 1-2 closely adheres to the conductive tape, so that the conductive tape on the surface of the wire core is connected to the support sleeve and the outer housing 4-1 through the shielding spring 1-2, thus realizing the function of grounding shielding.
[0079] This embodiment, as Figure 1 shown, is a schematic diagram of the overall cold press connection structure for the connection between the wire core and the pin. From the wire core end 1-7 to the contact end 1-6, it successively includes a locking sleeve 1-1, a shielding spring 1-2, a support sleeve 1-3, an outer insulating sleeve 1-4, and an inner insulator 1-5; the connection between each component adopts a plug-and-play connection method, rather than the traditional threaded connection.
[0080] As Figure 2As shown, it is the inner insulator 1-5 for connecting the wire core 1-7 and the contact end 1-6 in this embodiment. The inner insulator 1-5 shown is a cylindrical structure, and is grooved along its axial direction. A slot 1-51 for installing the contact pin 1-52 and connecting the wire core is provided in the slot. Each slot 1-51 on the inner insulator 1-5 is pressed into the pin 1-52 and then installed as a whole into the outer insulating sleeve 1-4. The connection between the inner insulator 1-5 and the outer insulating sleeve 1-4 adopts a plug-in method, so the positioning and fixation between the two require a separate structural design. Therefore, in this embodiment, a cantilever arm 1-53 is provided on the inner insulator 1-5, and multiple cantilever arms can be provided along its angular direction according to the size of the inner insulator. A concealed buckle 1-41 is provided on the outer insulating sleeve 1-4 at a position corresponding to the cantilever arm 1-53, as shown in FIG. Figure 3 As shown, when the inner insulator 1-5 is inserted into the outer insulating sleeve 1-4, the cantilever arm 1-53 is inserted into the concealed buckle 1-41, and the end surface of the cantilever arm 1-53 is flush with the end surface of the outer insulating sleeve 1-4.
[0081] One end of the outer insulating sleeve 1-4 is used to connect with one end of the support sleeve 1-3. In order to ensure a reliable connection between the two, a connecting arm 1-42 is provided on the end face of the outer insulating sleeve 1-4. The connecting arm 1-42 is distributed in a ring shape on the end face of the outer insulating sleeve 1-4, and the ring diameter is smaller than the diameter of the outer insulating sleeve 1-4. When connected with the support sleeve 1-3, the connecting arm 1-42 is inserted into the inner wall 1-31 of the support sleeve 1-3, and the end face 1-32 of the support sleeve 1-3 is pressed against the end face of the outer insulating sleeve 1-4, so that the cantilever arm is pressed against the end face 1-32 of the support sleeve 1-3, so that the inner insulator 1-5 cannot retreat, which plays a role of limiting. Figure 4 After the support sleeve 1-3 is installed as a whole, it is installed and connected with the locking sleeve 1-1.
[0082] like Figure 5 The figure shows a schematic diagram of the plug structure in this embodiment. The plug in this embodiment can realize automatic plug-in and plug-out locking when plugged into the socket. As long as there is no external force, there is no risk of the two falling off, which changes the technical defect of possible loosening in the traditional threaded connection.
[0083] like Figure 6As shown in the figure, the housing 2 includes two parts, an outer housing 2-1 and an inner housing 2-2. One end of the inner housing 2-2 is provided with a locking member 2-7 for locking connection with the socket. A notch is provided on the outer housing 2-1 corresponding to the locking member 2-7. To ensure the reliable connection between the inner housing 2-2 and the outer housing 2-1, two continuous inner sunk steps are provided inside the outer housing 2-1. The inner housing 2-2 is arranged on the innermost step. A cavity structure is formed between the inner housing 2-2 and the outer housing 2-1 by the outer step on the outer housing 2-2. A reset elastic member 2-3 is arranged in the cavity structure, and the elastic member 2-3 is sleeved on the inner housing 2-2 in a ring shape. The locking member 2-7 at one end of the inner housing 2-2 is a protruding structure, which extends out from the notch on the outer housing 2-1, and under the action of the reset elastic member 2-3, the locking member 2-7 moves back and forth in the notch. To ensure the locking effect, the symmetry plane of the locking member 2-7 is an inclined plane, so as to have a good force-bearing effect.
[0084] As Figure 7 shown, when using the plug housing, hold the outer housing 2-1 by hand and push the housing forcefully towards the mating socket housing. The locking member 2-7 on the inner housing 2-2 moves in the opposite direction after being squeezed by the socket housing. The outer housing 2-1 is inserted into the socket housing, and after the locking member 2-7 reaches the locking position, it is reset by the action of the reset spring 2-3 between the inner housing 2-2 and the outer housing 2-1 and locks with the socket housing. After locking, if there is no pulling force, the outer housing and the socket housing will not separate.
[0085] As Figure 8 and Figure 9 shown, it is a schematic diagram of the socket structure of this embodiment, including a housing assembly 3-1 and a contact body assembly 3-2. The housing assembly 3-1 and the contact body assembly 3-2 are not fixedly connected to each other and can be separated from each other. The structure of the housing assembly includes an integrally formed housing. One end of the housing is an installation end, and threads are provided on its outer side surface for installing and fixing the entire socket housing through a nut. The opposite end to the installation end is a connection end, and the inner side surface of the connection end port is an inclined surface 3-6 for guiding. A circular concave ring groove is provided along the circumferential direction of the wall surface inside the connection end. The inner wall surface between the ring groove and the inclined surface 3-6 is a protruding structure, forming a locking platform 3-5 of the entire socket housing. A protruding step is provided inside the socket housing along the direction from the installation end to the connection end for limiting the contact assembly 3-2; a groove for arranging a shielding spring 3-4 is provided on the wall surface near the connection end. In this embodiment, when the socket housing is used for an Ethernet connector, the shielding spring 3-4 can be fixedly installed. When the socket housing is not used for an Ethernet connector, the shielding spring 3-4 can be taken out from the groove.
[0086] In order to achieve accurate docking between the socket housing and the plug housing, an anti-misinsertion module is also provided on the socket housing for positioning and connecting with the key position on the plug housing. In addition, in order to achieve a good sealing effect, a sealing ring is also provided on the socket housing.
[0087] like Figure 10 As shown, it is a schematic diagram of the structure of the grounding pin 3-7 in the contact body assembly. The grounding pin 3-7 includes a shell contact point 3-74, a long arm 3-71, a fixing part 3-72, a positioning part 3-73 and a grounding contact point 3-75 from one end to the other. A plurality of slots are provided on the insulator in the contact body assembly. The grounding contact 3-75 of the grounding pin 3-7 shown is used for welding with the grounding wire after passing through the end face of the contact body assembly from the slot. The positioning part 3-73 is a smooth plane that fits the positioning plane in the slot, and the fixing part 3-72 is fixedly connected to the inner wall surface of the insulator. The long arm 3-71 is arranged in the slot, and the fixing part 3-72 and the positioning part 3-73 are the center, driving the contact point 3-74 to tilt up and down. When the entire contact body assembly is installed in the shell assembly 3-1, the long arm 3-71 is subjected to the extrusion force of the shell assembly and drives the contact point 3-74 to tilt up, and the contact point 3-74 contacts the inner wall of the shell assembly to ensure that the grounding end is effectively connected to the shell. In order to ensure the grounding effect, a plurality of grounding pins may be symmetrically arranged in the contact body assembly.
[0088] During the actual installation and connection process of the connector of this embodiment, the connection sequence is as follows:
[0089] First, if Figures 1-4 As shown, after the wire core and the contact are cold-pressed, the contact is inserted into the slot of the inner insulation. The outer insulation is inserted according to the key position (uniqueness, used to prevent errors), and the inner insulation and the contact are fixed with the hidden buckle of the outer insulation. The assembled whole is connected to the support sleeve, and the outer insulation connecting arm is tightly matched with the inner wall of the support sleeve through the key position of the opening hole, so that it becomes a whole (no external force is required, it will not loosen, and the open key is used to ensure the uniqueness of the installation direction). The end face of the support sleeve and the cantilever of the inner insulation are used to limit the axial movement of the inner insulation. The shielding spring (360 degrees) is used to connect the cable shielding and the preliminary locking wire. Then, the ribs in the circumferential direction of the locking sleeve are tightly matched with the inner wall of the support sleeve, and the inclined compression shielding spring is used to lock the cable and enhance the shielding density. In this way, a modular cold-pressed integral loading structure is formed, and the disassembly and reverse operation can be reversed according to the above loading principle.
[0090] Next, if Figures 5-7 As shown, the integrally cold-pressed wire core and contact piece are installed into the plug housing and fixed to each other by a lock nut.
[0091] like Figure 9As shown, the socket housing is fixed to the panel by a lock nut, while the contact body assembly is fixed by soldering to the circuit board and is arranged such that the contact body assembly is sleeved within the socket housing. In practice, the contact body assembly is not fixedly connected to the socket housing, and only the wire core is connected to the socket housing through a grounding pin.
[0092] Finally, when connecting the plug housing to the socket housing, the operator holds the outer housing 2-1 by hand and forcefully pushes the outer housing 2-1 in the direction of the socket housing assembly 3-1 for insertion. The locking member 2-7 on the inner housing 2-2 is under the action of the return spring, so that after being inserted into the housing assembly 3-1, it is hooked with the locking table 3-5 to achieve the connection of the socket and the plug. When it is necessary to release, hold the outer housing 2-1 and pull it in the opposite direction. Under the action of the return spring 2-3, the inner housing 2-2 is stressed, driving the locking member 2-7 to separate from the locking table 3-5.
[0093] The structure of this embodiment all adopts a plug-and-play structure to achieve connection. After the connection, if the connector is not affected by external forces, the two will not separate.
[0094] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
