, uncovered, but at the same time, if it is uncovered it is translucent as it allows for visual inspection of the cabling. The connection base design impedes that the modular meters may be placed in an inverted position by means of five asymmetrical guides set on the periphery of the receptacle. The neutral clamp electrode is set parallel to the potential clamp electrodes but not on the same plane in order to also avoid the inverted insertion and to minimize the opening of the clamps through the typical use of removing and placing meters by means of balancing movement, this adds the confidence, knowing that the modular meters are not set with false contacts and even de-energized; the modular meter cabinet design additionally allows that these be compatible with the ANSI type calibration table connectors which are half left, thus easing the verification and calibration process for the meters without the need of having to use additional adapters and cables. Each connection base has an optical port (without physical connection with the end goal of minimizing failures) to locally interrogate each meter, facilitating detection of any malfunction.

9 , seals, this design is based on a monolithic piece of machined steel which is placed at the door and which allows it to interact with a plate which acts as an electric backing plate which passes through a groove in the main body of the cabinet to be welded on its inner part thereby granting it structural resistance, the electric backing plate penetrates the interior of the machined block through another groove when the door is closed in such a way that upon combining these two pieces and the safety bolts set in a perpendicular manner to the opening of the door, it avoids that this can be forced by means of activating a lever, which grants the mechanism an exceptional resistance to any intrusion attempt, the witness lock type seals grant additional safety, given that these may only be opened upon breaking, thus leaving evidence of any type of unauthorized opening attempt, these witness lock type devices may be controlled by the electric energy supply company or by any of its contractors in charge of system maintenance. The MOM
consists of active safety elements with mechanical, optical and electromagnetic detectors, which upon opening the door of the MOM generate a registry of this event with the additional information regarding the day and time of the occurrence, this also allows having a remote notification at the operations center of the company providing the electric energy supply, the optic sensor can notify when upon opening the door of the MCM, the state of darkness is interrupted, while the magnetic interrupters detect when the metallic door is separated from the magnetic sensors.
The MCM is also provided with an outer optic port, which allows local communication with the control center of the cabinet which we shall call CCC from hereon after, to be able to carry out any operation with the modular meters and any remote module associated with these without the need of removing the bolts and seals in order to open the door. The modular meters and the CCC found in the inner part of the MCM can establish bidirectional communication with different operative modules found in the home or the local operative of the user, as could be the remote energy control, which is a module which has a screen which allows indicating to the user his total energy consumption in kilowatts per hour and the information which determines his bill, the client can also be notified by means of text messages with information such as payment due dates reminders, disconnection notices due to lack of prompt payment for services and even information regarding weather, notifications etc., the fact that companies providing electric energy supply services can , give the user information in real time of his consumption is a requirement established by law in a majority of third world countries; another satellite unit with which the control unit for supervising and monitoring systems consist with, are the remote modules which are used to establish communication by means of codified signals superimposed on the 60 Hertz feed line and which make up the nodules of a local intercommunication network which allows the interaction with the remote monitors and with the remote control modules which make it possible to remotely activate the turning on or turning off of lamps, air conditioning, heating etc. This local network can also include remote supervision modules, which allow monitoring and recording consumption of electronic, commercial or industrial apparatus for a determined period of time and provide the client information regarding an internet webpage so that he may know which equipment uses the most energy with the end goal of providing a more efficient consumption strategy.
FIG 1 shows the modular meter cabinet, which from now on will be referred to as MOM (1) with the access door (15) open, in its inner part the connection bases (7), (8), (9) and (10) can be seen set over a vertical block which itself forms a matrix with other similar assemblies, in this case A
, they form a matrix with 12 elements, as can be seen in FIG
1, all the connection bases are designed with a symmetrical geometry to prevent that the modular meters which are later connected to them, be placed in an inverted form which could cause incorrect functioning of the meters, FIG I also shows the electric backing plate (2) and the monolithic closure (3) both of which are in charge of keeping the access door (15) closed, on the upper right part of the door, the optic port can be seen (4), which allows reading the information collected by the cabinet control center, which from here on after shall be called CCC (31) which concentrates all the information regarding each one of the modular meters which are found in the inner part of the MCM (1), this information can be read from the outside by means of an optical interface thereby avoiding the need of opening the access door (15) which is highly convenient given that this is generally found closed and latched by means of the monolithic closure (3), the electric backing plate and various safety bolts and locks, on the upper part of the cabinet an insulating translucent plate can be seen which constitutes the cable protector (5), this plate allows viewing the disposition of the potential cables but avoids that these may be touched granting a greater protection f , CA 02885469 2015-03-09 level to the personnel of the electric energy supply company, on the upper part of the MOM (1) an antenna (6) can be seen, which is used to establish contact by radio with other elements of the system, this antenna (6) has a non-conductive cover so that the radio waves can be duly expanded and this antenna (6) is in communication with the inner part of the MOM (1) by means of a cable which passes through an orifice on the upper part of the MOM (1), otherwise, if the antenna were to connect to the interior, the metal which forms the box of the MOM (1), would act as a Faraday cage, impeding the functioning thereof. The MOM (1) box, consists with a series of mounting hardware, these are hardware for hanging (11) and hardware for embedding (12), which allow placing the MOM (1) on posts, pedestals, or on any type of commonly required situation. On the lower part of the MOM (1), the detection devices for opening the access door (15), these are: the optic alarm (13), the magnetic alarm (14) and the mechanical alarm (36); these three devices combined, make it almost impossible that the opening of the access door (15) would be able to go unnoticed by the CCC (31), when the CCC (31) detects any type of opening, it immediately generates an intrusion logbook and additionally reports an alert to the operations center of the company and information regarding where this action occurred.
FIG 2 shows the connection base (7) and the connection base (8) which form part of the connection base matrix arrangement to the inner part of the MOM (1), on the connection base one can see the primary contact clamp (16), the secondary contact clamp (17), and the ground clamp (18), these three clamp contacts retain the modular meters such as the modular meter (58) which are inserted into the connection base (7) and at the same time make the necessary electric contact towards the corresponding feeding phase, the neutral and the energy exit towards the user's installations, at the same time, the shape design of each connection base impedes the placement of the modular meters in a wrong position, this geometric configuration is undertaken based on the characteristics of the connection banks used in the ANSI type calibration apparatus, with which the government and the companies providing the electric service must calibrate the meters, the connection bases are also designed to form matrixes which in turn, allow having a great versatility in so far as the type of service available to the client, whether it be monophasic, biphasic or tri-phasic.

FIG 11 shows a modular meter (58) which is manufactured with three different types of plastic, the base plastic (59) which has more economic characteristics, the translucent enclosure (60) which allows the light passage through acting communication optic ports (66) and grants signage, advertisements and instructions placed under this enclosure protection, the high resistance front (61) is manufactured of a much more resistant material which helps grant structural rigidity to the blade fuse exits which in this case there are three, the main blade fuse (62), the secondary blade fuse (63) and the neutral connection blade (64), these three blades are respectively placed in parallel form but the neutral connection blade (64) is found at a different plane, this in addition to the outline design of the high resistance front (61) and the base connection designs such as the base connection (7) make possible that the modular meters such as the modular meter (58) be connected in an inverse manner, the high resistance front (61) is also equipped with one or more windows for optic port with inner communication (65), these windows allow for the establishing of an optic communication connection from the inner part of the modular meter (58) towards an optic interface placed on the back part of the connection bases.
The body of the modular meter (58) also has a space (67) to place identification cards.
FIG 12 shows the modular meter (58) shown in profile where it can be seen that the secondary blade fuse (63) and the neutral connection blade (64) are found on different planes but parallel. This disposition of the power blades and the neutral connection blade avoids that upon placing or removing the modular meters by balancing them, contact power can be lost between the clamps of the connection bases and the corresponding blades.
FIG 13 shows a block diagram of the modular meters, in this case the modular meter (58) has three electric connection blades, the main power blade (62), the secondary power blade (63) and the neutral connection blade (64), the phase energy emanating from the transformer of the company providing the electric energy supply, is connected to the main power blade (62) by placing the modular meter (58), in one of the connection bases which consists with the MCM (1) at the same time the neutral connection blade (64) closes the circuit by also connecting in neutral through the connection base, this provides energy to the transformer and the local energy source (69) which in turn is in charge of energizing all the electronic elements of the modular meter (58), the corresponding energy phase is sent to the user by means of the relay action (68) which is of the bistable type, this exit is connected to the corresponding connection base through the secondary blade fuse (63), this relay (68) allows connecting or disconnecting the service to the client when required, based on the order generated at the digital control unit (71), an analog meter unit (70), measures at all times, the amount of current flowing towards the secondary power fuse (63) so that the digital control unit (71) applies the necessary calculation procedures to determine the amount of energy consumed by the user and the amount owed for this, the modular meter (58) additionally consists with a primary optic link circuit (72) and a secondary optic link circuit (74), a bi-directional radio communication unit (73) allows communication between local meter networks, remote modular, monitors and peripheral accessories such as communication networks with greater reach such as could be long distance radio links, LAN type meter networks, Ethernet, land base telephones up to a general administration central unit, this two way communication (total duplex), allows the meters to operate remotely and in an unattended manner, the modular meters are prepared for future expansions and reconfigurations which the energy supply company may come to need, all the programming, interrogation as well as their updates are made through the communication networks, which facilitates the possibility of remotely programming of basic fees, post-payment, pre-payment, hourly rates, control of demand, etc.
The modular meters such as the modular meter (58) may be equipped with a simple optic signaling system based on three colors, which allow the personnel of the electric supply company with minimum training and without the use of special tools or special software the possibility of inspecting and diagnosing the state of the modular meters, in this case using three light emitting diodes with green, blue and red lights a complete diagnosis of the equipment can be made in the following manner: the intermittent green LED light signifies that the modular meter (58) is operating correctly, a turned off green LED light indicates that the modular meter has an error; intermittent blue LED light signifies that the modular meter (58) is duly linked with the CCC (31), a turned off blue LED light indicates a lack of communication with the CCC (31); intermittent red LED
, light signals disconnected service to the client (open relay (68)); turned off red LED signifies that service to the client has been connected (closed relay (68)). All these LED
signal functions are controlled by means of the digital control unit (71) through the LED signal sub module (105).
FIG 14 shows one of the possible communications linkage configurations, which may be used with the control unit for supervising and monitoring systems of electric energy supply, in this scheme, the modular meters (58 and 81) are found linked to two respective but separate remote modules (76 and 87) by means of the radial communication network (75) and the radial communication network (86) respectively, in turn, the remote energy monitors (78 and 89) themselves are linked to the entire system by means of PLC type communication (77 and 88) networks respectively, this last communication system uses median frequency modulated and codified signals over the same electric energy feeding lines, in a similar manner to the international X10 system but with a much greater degree of sophistication, the information handled towards the equipment of each one of the users is not mixed nor interferes with each other, given that the personal identification code is used which is automatically determined upon installing the equipment, in such a way that the personnel does not have to resort to the use of computers or programmers to assign identification coded to each equipment, given that this entire process is undertaken in an automatic manner from the inner parts of the MCM (1) circuits. The remote energy monitors such as (78 and 79) allow the user to know his consumption at any given time and at the same time allow for receiving messages from the central administrative office of the electric energy supply company, such as disconnection messages due to lack of payment, payment date reminder etc.
The remote modules such as (76 and 87) are local network nodes and serve as information centers and links;
FIG 14 also shows that modular meters (58 and 81) are linked to a communication network with broad coverage as could be the internet, in such a way that from the energy supply control center (80), the electric energy supply company can have complete control of the service in regards to supervision, operational, fee collection and direct control of the service to the users.
FIG 15 shows a modular meter (58), which can be directly connected by means of a main blade fuse (62), a secondary blade fuse (63) and the neutral connection blade (64) to the base of the ANSI calibration unit (82), upon introducing the blade fuses into the respective connectors (83 and 85), the neutral connection plug (64) comes into contact with the ground contact line (84) of the calibration unit, the modular meters fit perfectly into the plug entrances and they remain within the circumscription of the inner border of the inner circumference of the calibration base (90), this is very important because both the government as well as the electric energy supply companies require that the meters be calibrated and their operation verified and that this design for the enclosure of modular meters such as modular meters (58) allows to directly connect them to the test banks without the need of either adapters or connection cables.
In FIG 16 the design of the closure mechanism of the MOM (1) can be seen, the closure system basically consists of two main elements, the electric backing plate (2) which is found welded from the inner part of the MOM (1) and the monolithic closure (3) which is a piece machined from a single metal block and which is firmly fixed unto the access door (15), the electric backing plate (2) passes through a groove (94) made on the access door (15) to later penetrate into the monolithic closure (3) in light of a groove being conveniently machined on the monolithic closure (3) on the , , face, which comes into contact with the access door (15), when the access door (15) is closed, the orifices which go from side to side through the electric backing plate (2) and the monolithic closure (3) remain free, theses orifices are the entrance orifice (91) for a main bolt or rupture bolt (95) and the entrance orifice (92) for a lock bolt (96), the groove (93) for the main witness lock (98) can also be seen.
In FIG 17 one can see in more detail, the parts which make up the safety mechanism, the rupture bolt (95), requiring a special tool to remove it once it has been introduced into the body of the monolithic closure (3), the lock bolt (96) which crosses the monolithic closure (3) and the electric backing plate (2) passing from side to side to be introduced into the bolt lock (97), the main witness lock (98), and the secondary witness lock (99) give the electric energy supply company and those in charge of supervising and maintaining the control units for supervision and monitoring systems, a greater flexibility given that these witness locks must be destroyed in order to open them, thus leaving proof that the access door (15) was opened.
In FIG 18 the safety closure system installed with the main witness lock (98) as well as the secondary witness lock (99) and the bolt lock (97) can be seen, this closure system , is extremely safe because it is practically impossible to open it by using the lever of the access door (15), given that the bolts (95 and 96) are found in transversal manner regarding the direction of the aperture of the access door (15), in FIG 19 one can also see in more detail the machining of the monolithic closure (3), showing the groove (102) which allows the entrance of the electric backing plate (2) into the inner part of the monolithic closure (3), upon this taking place, the entrance orifice (92) for the lock bolt remains free from side to side, while the entrance orifice (91) for the main bolt or rupture, penetrates further than half the body of the monolithic closure (3), this figure also shows the groove (103) for a secondary witness lock.
FIG 20 shows the electric backing plate (2) with the orifice (100) to fasten the rupture bolt (95) and the orifice (101) to fasten the lock bolt (96), one can also see the groove (93) for the main witness lock (98), the shape of the electric backing plate (2) doubled at ninety degrees allows introducing it from the inner part of the MCM (1) body to weld it into position, which grants it greater structural resistance.

consists of active safety elements with mechanical, optical and electromagnetic detectors, which upon opening the door of the MOM generate a registry of this event with the additional information regarding the day and time of the occurrence, this also allows having a remote notification at the operations center of the company providing the electric energy supply, the optic sensor can notify when upon opening the door of the MCM, the state of darkness is interrupted, while the magnetic interrupters detect when the metallic door is separated from the magnetic sensors.
The MCM is also provided with an outer optic port, which allows local communication with the control center of the cabinet which we shall call CCC from hereon after, to be able to carry out any operation with the modular meters and any remote module associated with these without the need of removing the bolts and seals in order to open the door. The modular meters and the CCC found in the inner part of the MCM can establish bidirectional communication with different operative modules found in the home or the local operative of the user, as could be the remote energy control, which is a module which has a screen which allows indicating to the user his total energy consumption in kilowatts per hour and the information which determines his bill, the client can also be notified by means of text messages with information such as payment due dates reminders, disconnection notices due to lack of prompt payment for services and even information regarding weather, notifications etc., the fact that companies providing electric energy supply services can , give the user information in real time of his consumption is a requirement established by law in a majority of third world countries; another satellite unit with which the control unit for supervising and monitoring systems consist with, are the remote modules which are used to establish communication by means of codified signals superimposed on the 60 Hertz feed line and which make up the nodules of a local intercommunication network which allows the interaction with the remote monitors and with the remote control modules which make it possible to remotely activate the turning on or turning off of lamps, air conditioning, heating etc. This local network can also include remote supervision modules, which allow monitoring and recording consumption of electronic, commercial or industrial apparatus for a determined period of time and provide the client information regarding an internet webpage so that he may know which equipment uses the most energy with the end goal of providing a more efficient consumption strategy.
FIG 1 shows the modular meter cabinet, which from now on will be referred to as MOM (1) with the access door (15) open, in its inner part the connection bases (7), (8), (9) and (10) can be seen set over a vertical block which itself forms a matrix with other similar assemblies, in this case A
, they form a matrix with 12 elements, as can be seen in FIG
1, all the connection bases are designed with a symmetrical geometry to prevent that the modular meters which are later connected to them, be placed in an inverted form which could cause incorrect functioning of the meters, FIG I also shows the electric backing plate (2) and the monolithic closure (3) both of which are in charge of keeping the access door (15) closed, on the upper right part of the door, the optic port can be seen (4), which allows reading the information collected by the cabinet control center, which from here on after shall be called CCC (31) which concentrates all the information regarding each one of the modular meters which are found in the inner part of the MCM (1), this information can be read from the outside by means of an optical interface thereby avoiding the need of opening the access door (15) which is highly convenient given that this is generally found closed and latched by means of the monolithic closure (3), the electric backing plate and various safety bolts and locks, on the upper part of the cabinet an insulating translucent plate can be seen which constitutes the cable protector (5), this plate allows viewing the disposition of the potential cables but avoids that these may be touched granting a greater protection f , CA 02885469 2015-03-09 level to the personnel of the electric energy supply company, on the upper part of the MOM (1) an antenna (6) can be seen, which is used to establish contact by radio with other elements of the system, this antenna (6) has a non-conductive cover so that the radio waves can be duly expanded and this antenna (6) is in communication with the inner part of the MOM (1) by means of a cable which passes through an orifice on the upper part of the MOM (1), otherwise, if the antenna were to connect to the interior, the metal which forms the box of the MOM (1), would act as a Faraday cage, impeding the functioning thereof. The MOM (1) box, consists with a series of mounting hardware, these are hardware for hanging (11) and hardware for embedding (12), which allow placing the MOM (1) on posts, pedestals, or on any type of commonly required situation. On the lower part of the MOM (1), the detection devices for opening the access door (15), these are: the optic alarm (13), the magnetic alarm (14) and the mechanical alarm (36); these three devices combined, make it almost impossible that the opening of the access door (15) would be able to go unnoticed by the CCC (31), when the CCC (31) detects any type of opening, it immediately generates an intrusion logbook and additionally reports an alert to the operations center of the company and information regarding where this action occurred.

FIG 13 shows a block diagram of the modular meters, in this case the modular meter (58) has three electric connection blades, the main power blade (62), the secondary power blade (63) and the neutral connection blade (64), the phase energy emanating from the transformer of the company providing the electric energy supply, is connected to the main power blade (62) by placing the modular meter (58), in one of the connection bases which consists with the MCM (1) at the same time the neutral connection blade (64) closes the circuit by also connecting in neutral through the connection base, this provides energy to the transformer and the local energy source (69) which in turn is in charge of energizing all the electronic elements of the modular meter (58), the corresponding energy phase is sent to the user by means of the relay action (68) which is of the bistable type, this exit is connected to the corresponding connection base through the secondary blade fuse (63), this relay (68) allows connecting or disconnecting the service to the client when required, based on the order generated at the digital control unit (71), an analog meter unit (70), measures at all times, the amount of current flowing towards the secondary power fuse (63) so that the digital control unit (71) applies the necessary calculation procedures to determine the amount of energy consumed by the user and the amount owed for this, the modular meter (58) additionally consists with a primary optic link circuit (72) and a secondary optic link circuit (74), a bi-directional radio communication unit (73) allows communication between local meter networks, remote modular, monitors and peripheral accessories such as communication networks with greater reach such as could be long distance radio links, LAN type meter networks, Ethernet, land base telephones up to a general administration central unit, this two way communication (total duplex), allows the meters to operate remotely and in an unattended manner, the modular meters are prepared for future expansions and reconfigurations which the energy supply company may come to need, all the programming, interrogation as well as their updates are made through the communication networks, which facilitates the possibility of remotely programming of basic fees, post-payment, pre-payment, hourly rates, control of demand, etc.
The modular meters such as the modular meter (58) may be equipped with a simple optic signaling system based on three colors, which allow the personnel of the electric supply company with minimum training and without the use of special tools or special software the possibility of inspecting and diagnosing the state of the modular meters, in this case using three light emitting diodes with green, blue and red lights a complete diagnosis of the equipment can be made in the following manner: the intermittent green LED light signifies that the modular meter (58) is operating correctly, a turned off green LED light indicates that the modular meter has an error; intermittent blue LED light signifies that the modular meter (58) is duly linked with the CCC (31), a turned off blue LED light indicates a lack of communication with the CCC (31); intermittent red LED
, light signals disconnected service to the client (open relay (68)); turned off red LED signifies that service to the client has been connected (closed relay (68)). All these LED
signal functions are controlled by means of the digital control unit (71) through the LED signal sub module (105).
FIG 14 shows one of the possible communications linkage configurations, which may be used with the control unit for supervising and monitoring systems of electric energy supply, in this scheme, the modular meters (58 and 81) are found linked to two respective but separate remote modules (76 and 87) by means of the radial communication network (75) and the radial communication network (86) respectively, in turn, the remote energy monitors (78 and 89) themselves are linked to the entire system by means of PLC type communication (77 and 88) networks respectively, this last communication system uses median frequency modulated and codified signals over the same electric energy feeding lines, in a similar manner to the international X10 system but with a much greater degree of sophistication, the information handled towards the equipment of each one of the users is not mixed nor interferes with each other, given that the personal identification code is used which is automatically determined upon installing the equipment, in such a way that the personnel does not have to resort to the use of computers or programmers to assign identification coded to each equipment, given that this entire process is undertaken in an automatic manner from the inner parts of the MCM (1) circuits. The remote energy monitors such as (78 and 79) allow the user to know his consumption at any given time and at the same time allow for receiving messages from the central administrative office of the electric energy supply company, such as disconnection messages due to lack of payment, payment date reminder etc.
The remote modules such as (76 and 87) are local network nodes and serve as information centers and links;
FIG 14 also shows that modular meters (58 and 81) are linked to a communication network with broad coverage as could be the internet, in such a way that from the energy supply control center (80), the electric energy supply company can have complete control of the service in regards to supervision, operational, fee collection and direct control of the service to the users.
FIG 15 shows a modular meter (58), which can be directly connected by means of a main blade fuse (62), a secondary blade fuse (63) and the neutral connection blade (64) to the base of the ANSI calibration unit (82), upon introducing the blade fuses into the respective connectors (83 and 85), the neutral connection plug (64) comes into contact with the ground contact line (84) of the calibration unit, the modular meters fit perfectly into the plug entrances and they remain within the circumscription of the inner border of the inner circumference of the calibration base (90), this is very important because both the government as well as the electric energy supply companies require that the meters be calibrated and their operation verified and that this design for the enclosure of modular meters such as modular meters (58) allows to directly connect them to the test banks without the need of either adapters or connection cables.
In FIG 16 the design of the closure mechanism of the MOM (1) can be seen, the closure system basically consists of two main elements, the electric backing plate (2) which is found welded from the inner part of the MOM (1) and the monolithic closure (3) which is a piece machined from a single metal block and which is firmly fixed unto the access door (15), the electric backing plate (2) passes through a groove (94) made on the access door (15) to later penetrate into the monolithic closure (3) in light of a groove being conveniently machined on the monolithic closure (3) on the , , face, which comes into contact with the access door (15), when the access door (15) is closed, the orifices which go from side to side through the electric backing plate (2) and the monolithic closure (3) remain free, theses orifices are the entrance orifice (91) for a main bolt or rupture bolt (95) and the entrance orifice (92) for a lock bolt (96), the groove (93) for the main witness lock (98) can also be seen.
In FIG 17 one can see in more detail, the parts which make up the safety mechanism, the rupture bolt (95), requiring a special tool to remove it once it has been introduced into the body of the monolithic closure (3), the lock bolt (96) which crosses the monolithic closure (3) and the electric backing plate (2) passing from side to side to be introduced into the bolt lock (97), the main witness lock (98), and the secondary witness lock (99) give the electric energy supply company and those in charge of supervising and maintaining the control units for supervision and monitoring systems, a greater flexibility given that these witness locks must be destroyed in order to open them, thus leaving proof that the access door (15) was opened.
In FIG 18 the safety closure system installed with the main witness lock (98) as well as the secondary witness lock (99) and the bolt lock (97) can be seen, this closure system , is extremely safe because it is practically impossible to open it by using the lever of the access door (15), given that the bolts (95 and 96) are found in transversal manner regarding the direction of the aperture of the access door (15), in FIG 19 one can also see in more detail the machining of the monolithic closure (3), showing the groove (102) which allows the entrance of the electric backing plate (2) into the inner part of the monolithic closure (3), upon this taking place, the entrance orifice (92) for the lock bolt remains free from side to side, while the entrance orifice (91) for the main bolt or rupture, penetrates further than half the body of the monolithic closure (3), this figure also shows the groove (103) for a secondary witness lock.
FIG 20 shows the electric backing plate (2) with the orifice (100) to fasten the rupture bolt (95) and the orifice (101) to fasten the lock bolt (96), one can also see the groove (93) for the main witness lock (98), the shape of the electric backing plate (2) doubled at ninety degrees allows introducing it from the inner part of the MCM (1) body to weld it into position, which grants it greater structural resistance.
