Description

[0001] This disclosure relates to data and / or power connectors for respiratory devices, and specifically, but not exclusively, to connector devices for wearable support frames for respiratory devices. Background Technology

[0002] Breathing devices (such as stand-alone breathing apparatus) typically consist of a wearable support frame or backplate that supports the container of breathing gas and is worn on the user's back using shoulder straps and a waist belt. Modern breathing devices may incorporate onboard electronics such as communication equipment, telemetry, lights, cameras, sensors, and other electronic systems. These electronic systems can be powered by, for example, an onboard battery provided on the backplate, and may require data transmission to and from the electronics. Therefore, a connector system may be needed for data and / or power transmission with the breathing device.

[0003] Importantly, the charging and data transmission connector system is robust and easily attachable to the backplane. Furthermore, it is crucial that the connector system is suitable for use in hazardous environments where the breathing apparatus will operate. Many connectors used in non-safety-critical applications (such as consumer electronics) are simply not reliable and robust enough to meet the hazards and requirements faced by emergency service breathing apparatus.

[0004] Therefore, it should be understood that in specific areas of respiratory devices, improvements may be needed in connector systems used for data and power transmission. Summary of the Invention

[0005] According to one aspect of this disclosure, a connector system is provided for a wearable support frame for a breathing device according to the appended independent claim 1. The connector system includes a first connector disposed on the wearable support frame and a second connector for connection to the first connector. The first connector includes an electrical transmission element and a magnetic attraction element attracted by a magnet. The second connector includes a complementary electrical transmission element for transmitting power and / or data with the electrical transmission element of the first connector, and further includes a magnet for attracting the magnetic attraction element to magnetically secure the first and second connectors to each other for transmitting power and / or data between the electrical transmission elements.

[0006] The first connector may include a plurality of magnetic attraction elements, and the second connector may include a plurality of corresponding magnets for attracting the plurality of magnetic attraction elements.

[0007] At least two of the magnetic attraction elements may be arranged on opposite sides of the electrical transmission elements, and at least two of the magnets may be arranged on opposite sides of the complementary electrical transmission elements.

[0008] The magnetic attraction element can be covered by a non-conductive material so that it is not exposed on the surface of the first connector. The non-conductive material can be a potting resin.

[0009] Electrical transmission elements and complementary electrical transmission elements can be conductive contacts or inductive electrical elements.

[0010] The magnet can be a permanent magnet or an electromagnet.

[0011] The first connector may also include a protrusion or recess having an electrical transmission element, and the second connector may also include a complementary recess or protrusion having a complementary electrical transmission element.

[0012] A connector system may include multiple electrical transmission elements and corresponding multiple complementary electrical transmission elements. At least one pair of electrical transmission elements and complementary electrical transmission elements may be configured to transmit electrical power, and at least one pair of electrical transmission elements and complementary electrical transmission elements may be configured to transmit data.

[0013] The second connector may include a cover configured to cover the magnet to prevent ferrous metal objects from unintentionally attaching to the second connector when it is not in use. The cover may be movable, such as by hinges, into and out of a covered position (i.e., between a covered and uncovered position). The cover may be made of a resilient material. The cover may include a ferrous metal magnetic element configured to attract the magnet.

[0014] According to a second aspect, a connector system for transmitting power and / or data is provided according to the appended independent claim 13. The connector system includes a first connector comprising a contact protrusion having at least a first electrical contact and a second electrical contact. These electrical contacts define a contact axis along a straight line extending between the first and second contacts. The connector system also includes a second connector comprising a complementary recess for receiving the contact protrusion, the complementary recess having complementary electrical contacts for contacting the first and second electrical contacts of the first connector. At least one of the first and second connectors is attached to a cable, and at the connection interface between the cable and the connector, the longitudinal axis of the cable is substantially perpendicular to the contact axis.

[0015] The contact protrusion and the complementary recess may each include an outer peripheral surface that is inclined relative to the longitudinal axis of the cable. The inclined outer peripheral surfaces may be configured to cover each other when the first connector and the second connector are in a connection configuration.

[0016] The inclined outer peripheral surface can be tilted relative to the longitudinal axis of the cable, such that in a connection configuration, when the inclined outer peripheral surfaces move relative to each other, the tension applied to the cable will cause the first connector and the second connector to disconnect.

[0017] The contact protrusion and / or complementary recess may have the longest dimension, particularly in a plan view, extending substantially perpendicular to the longitudinal axis of the cable. The longest dimension of the protrusion and / or recess may extend substantially together with or parallel to the contact axis.

[0018] The inclined outer peripheral surface may be disposed on the opposite outer peripheral side of the contact protrusion and / or the recess that complements the connection interface between the cable and the connector. The outer peripheral wall of the protrusion or recess may face the cable, and the inclined outer peripheral surface may be disposed on the opposite side of the protrusion or recess from the cable.

[0019] The first and / or second connector may include a connector portion on which contact protrusions or complementary portions are disposed. The connector portion may be substantially planar or flat. The connector may also include a stepped portion comprising a connection interface between the cable and the connector, such that the longitudinal axis of the cable is spaced apart from the connector portion. In other words, the cable may intersect the connector such that the cable is spaced apart from the other connector to a greater extent than the connector portion.

[0020] The first and second connectors each include three or more electrical contacts arranged on a contact axis. All electrical contacts of the connectors may be arranged on the respective contact axes.

[0021] The contact protrusions and complementary recesses may each include one or more additional peripheral inclined surfaces that may be parallel to the longitudinal axis of the cable, such that in a connection configuration, as these additional inclined peripheral surfaces move relative to each other, a lateral force applied to the connectors that is not aligned with the longitudinal axis of the cable will cause the first and second connectors to disconnect.

[0022] At least one pair of electrical contacts and complementary electrical contacts can be configured to transmit power, and at least one pair of electrical contacts and complementary electrical contacts can be configured to transmit data.

[0023] In a third aspect, a connector device for a wearable support frame for a breathing apparatus is provided, the connector device comprising: a first connector including a contact protrusion having at least one electrical contact; a second connector including a complementary contact recess having complementary electrical contacts; wherein the electrical contacts and the complementary electrical contacts are connectable to provide power and / or data transmission; wherein one of the first connector and the second connector includes: a positioning protrusion adjacent to the contact recess or the contact protrusion, the positioning protrusion extending outwardly from the first connector; and the other of the first connector and the second connector includes: a complementary positioning recess within which the positioning protrusion is locating in a connection configuration of the first connector and the second connector; the positioning protrusion and the positioning recess are arranged such that connection of the electrical contacts is possible only in a single relative orientation of the first connector and the second connector; wherein the contact protrusion, the complementary contact recess, the positioning protrusion, and the positioning recess each include an angled surface such that a force is applied in a direction transverse to the extension direction of the protrusion to separate each protrusion and the complementary recess, and thus separate the first connector and the second connector.

[0024] In the first, second, and third aspects, the connector disposed on the wearable support frame may be disposed on the rear surface of the wearable support frame, which is configured to face the user's back during use. The connector may be disposed on the front surface of the wearable support frame, which faces away from the user's back during use.

[0025] According to a fourth aspect, a wearable support frame for a breathing device is provided, the wearable support frame including a connector system according to one or more of the first, second, and third aspects.

[0026] According to the fifth aspect, a breathing device is provided that includes a wearable support frame according to the fourth aspect.

[0027] According to a sixth aspect, a respirator charging system is provided, comprising a respirator according to a fifth aspect and a charging device, the charging device including a second connector. The charging device is configured to charge the respirator via a first connector and a second connector.

[0028] To avoid unnecessary repetition and redundant wording in this specification, certain features are described only with respect to one or more aspects or embodiments of the invention. However, it should be understood that, where technically possible, the features described with respect to any aspect or embodiment of the invention may also be used with respect to any other aspect or embodiment of the invention.

[0029] In particular, one, two, or all three of the first, second, and third aspects can be embodied in the same connector device. Attached Figure Description

[0030] To better understand the invention and to more clearly illustrate how the invention can be practiced, reference will now be made to the accompanying drawings by way of example, in which:

[0037] Figure 7 This is a cross-sectional view of an alternative connector with a cable. Detailed Implementation

[0038] Figure 1 A respirator connector system is shown, and specifically a respirator charging system is illustrated. While the system shown is a charging system, it is also capable of transmitting data to and from the respirator. It should be understood that the connector system can be used to transmit power, data, or both. The data to be transmitted may include usage data, telemetry data, battery health data, or other types of data related to the respirator.

[0039] The breathing apparatus charging system includes a breathing apparatus 1 and a charging device 2 (not shown). Breathing apparatus 1 (e.g., Figure 1 As shown, Figure 1 The diagram (a front plan view of the breathing device 1) includes a wearable support frame 12, specifically a back panel 12, configured to be supported on the user's back using shoulder straps 14 and a waist belt 16. The back panel 12 is configured to support a breathing cylinder (not shown), which is secured to the back panel using support straps 18 and a pressure relief valve 20.

[0040] Figure 2A plan view of the rear of the breathing device 1 and the charging device 2 is shown. This side of the back panel 12 is arranged to rest against the user's back during use. The back panel 12 also includes an electronic module 22 centrally arranged on the back panel 12. The electronic module 22 includes at least one battery and various controllers for transmitting and receiving data.

[0041] exist Figure 2 The connector system 100 can be seen in the image. In this example, the connector system is arranged on the user-facing side or rear side of the back panel 12, but in other examples, it may be arranged on the front side or at some other location on the back panel. By providing part or all of the connector system on the rear of the back panel 12, the connector system can be better protected from hazardous operating environments during use.

[0042] Connector system 100 in Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The details are shown below and should be cited together with the description below.

[0043] Figure 3 A detailed perspective view of the first connector 102 of the connector system 100 is shown. The first connector 102 is arranged on the backplate 12. Figure 4 As shown, the connector system 100 also includes a second connector 104 for connection to the first connector 102. The first connector 102 and the second connector 104 are configured to connect to provide power and data transmission between the breathing apparatuses, specifically to charge the battery of the electronics module 22 and to send and receive data from and from the controller of the electronics module 22.

[0044] The first connector 102 includes at least one electrical transmission element, in this case, three electrical contacts 106. In other instances, an inductive transmission element or other wireless transmission element may be provided. The second connector includes at least one electrical transmission element (corresponding to one or more electrical transmission elements), in this case, three complementary electrical contacts 108 configured to contact the electrical contacts 106 of the first connector to transmit electrical signals. The contacts on each connector are arranged in a straight line, having two external contacts and one center contact. One of the external contact pairs 106a, 108a is configured to transmit data to and from the electronics module 22, another external contact pair 106c, 108c is configured to transmit power to charge the battery of the electronics module 22, and the center third contact pair 106b, 108b is configured to provide ground.

[0045] The first connector 102 includes a flat, generally rectangular surface 110 defined by an outer peripheral edge 112. A protrusion 114 is provided projecting from the surface 110. The protrusion 114 has a flat raised surface 116 on which electrical contacts 106 are disposed. The raised surface 116 is generally rectangular and is defined by upwardly extending outer peripheral walls 136, 140, 142.

[0046] refer to Figure 5 The first connector 102 includes a first magnetic attraction element 120a and a second magnetic attraction element 120b that can be attracted by a magnet. The magnetic attraction elements 120a and 120b are ferromagnetic elements that do not generate a magnetic field themselves but can be attracted to a magnet (such as a permanent magnet or an electromagnet). Importantly, the magnetic attraction elements 120a and 120b are not permanently magnetized, as will be explained below. In this example, the magnetic attraction elements 120a and 120b are blocks of ferromagnetic material (such as steel). Elements 120a and 120b are sealed beneath a layer of non-conductive material (such as encapsulating or potting resin), thereby preventing them from being exposed on surface 110.

[0047] Turn now Figure 4 The second connector 104 shown is generally rectangular in shape and includes a generally rectangular surface 122 that is complementary to the rectangular surface 110 of the first connector 102. The second connector 104 includes a recess 124 on the surface 122, which is complementaryly shaped and positioned such that when the second connector is arranged to cover the first connector, the protrusion 114 is received in the recess 124, while the second connector 104 is in close abutment to the edge 112 of the first connector. The recess 124 has a recessed flat surface 126 on which a complementary contact 108 is disposed to contact a contact 106 when the connectors 102 and 104 are connected and the protrusion 114 is received in the recess 124. The complementary contact 108 is spring-loaded such that when the protrusion 114 is properly received in the recess 124, the contact 106 causes the complementary contact 108 to retract slightly into the surface 126.

[0048] The second connector 104 includes a first magnet 128a and a second magnet 128b for attracting the magnetic attraction elements 120a and 120b of the first connector 102. In this case, the magnets 128a and 128b are permanent magnets, but they can alternatively be electromagnets, etc. The magnets 128a and 120b generate their own magnetic fields so as to attract the magnetic attraction elements 120a and 120b respectively when the connectors 102 and 104 are connected together. The magnetic attraction elements 120a and 128b are positioned on the respective connectors 102 and 104 such that they substantially cover each other when the connectors 102 and 104 are connected. Thus, by magnetically attracting the element 120a, the magnet 128 magnetically secures the first and second connectors to each other, wherein their contacts 106 and 108 are in contact, enabling electrical and / or data transmission. Connectors 102 and 104 are in... Figure 5 The connection configuration is shown in the diagram, in which magnet 128 covers and attracts magnetic attraction element 120, and contacts 106, 108 remain in contact to allow for electrical and data transmission.

[0049] In this example, two magnetic attraction elements 120 are arranged on opposite sides of contact 106 (and protrusion 114), and two magnets 128 are similarly arranged on opposite sides of complementary contact 108 (and recess 124). This provides a stronger connection between connectors 102 and 104 by providing a retaining force on opposite sides of the contacts.

[0050] In the specific field of breathing apparatus, providing non-magnetized elements on the backplate can be advantageous. Magnetized elements on the backplate (i.e., magnets that generate their own magnetic field) can attract debris and other objects from hazardous environments, posing a dangerous entanglement hazard to the user. Therefore, by placing the magnetized portion of the connector holding system on a second connector that is not on the backplate, the increased risk of entanglement can be avoided. Furthermore, by covering the magnetic attraction elements with a non-conductive material to prevent their exposure on the outer surface of the connector on the backplate, the spark hazard can be reduced (this is important in hazardous atmospheres including those containing flammable gases), as sparks could occur if the metallic material of the element is exposed.

[0051] When used by firefighters, the backplate is subjected to temperatures ranging from 250°C. Magnets heated above their maximum operating temperature may degrade and lose performance over time, even after cooling. By placing the permanent magnets on a second connector that is not part of the backplate, the magnets are not exposed to high ambient temperatures, and the maximum operating temperature of the magnetic material can be eliminated from material selection constraints. This allows for the use of a wider range of magnetic materials and reduces / avoids the need to replace magnets during the product's lifespan.

[0052] The following text will refer to again Figures 3 to 6 Another aspect of the connector system 100 will be discussed.

[0053] The electrical contacts 106 of the first connector 102 define a contact axis C1 along a straight line extending between the contacts 106. Similarly, the complementary contacts 108 of the second connector 104 define a contact axis C2. When the first and second connectors are in a connected configuration, as... Figure 5 As shown, it will be understood that when contacts 106 and 108 are in contact, the contact axes C1 and C2 will be substantially coaxial.

[0054] In this example, a second connector is attached to cable 130, the other end of which is connected to charging device 2. Cable 130 connects complementary contacts 108 to provide power and data transmission with contacts 106 of the first connector 102. Cable 130 is connected to the second connector 104 via connection interface 132. At connection interface 132, the cable is secured to the connector by cable restraint 134. The longitudinal axis L of cable 130 is substantially perpendicular to the contact axis C2 of the second connector, and also perpendicular to the contact axis C1 of the first connector when connectors 102 and 104 are connected.

[0055] The protrusion 114 of the first connector 102 includes an outer peripheral surface 136 that is inclined relative to the cable axis L when the connector is connected. In the connection configuration, the inclined outer peripheral surface 136 is arranged on the side of the protrusion 114 opposite to the cable 130. The inclination of the surface 136 causes the protrusion 114 to taper with increasing distance from the surface 110. The recess 124 includes a complementary outer peripheral surface 138, such as... Figure 5 As shown, the complementary outer peripheral surface is configured to cover the outer peripheral surface 136 of the protrusion 114 in the connection configuration. Surface 138 is similarly inclined relative to the longitudinal axis L of the cable 130 and is similarly arranged on the side of the recess 124 opposite to the cable 130 (and its connection interface 132 with the connector 104).

[0056] The tilt of surfaces 136 and 138 causes the tension applied to the cable in the connection configuration (by...) Figure 5 Arrow F in the diagram indicates that the second connector 104 will tilt away from the first connector 102 due to the contact between surfaces 136 and 138, as shown in the diagram. Figure 5 As indicated by arrow M in the diagram. This movement of connectors 102 and 104 away from each other increases the distance between the magnetic attraction element 120 and the magnet 128, thereby reducing the magnetic holding force and allowing connectors 102 and 104 to be disconnected using only the tension on the cable 130.

[0057] Contacts 106 and 108 are arranged along an axis generally perpendicular to the cable 130, meaning that when tension is applied to the cable, contact pairs 106a, 106b, 106c and 108a, 108b, 108c are more likely to disconnect substantially simultaneously. If the contact pairs disconnect at slightly different times, this may reduce the risk of short circuits and other electrical problems.

[0058] Turn Figure 6 The second connector 104 is shown in a plan view. As can be observed, the recess 124 has a longest dimension D that extends generally perpendicular to the longitudinal axis L of the cable 130, i.e., generally parallel to the contact axis C2.

[0059] In this example, the protrusion 114 and the complementary recess 124 also include two additional peripheral beveled surfaces 140, which are disposed at the short ends of the protrusion and the recess and extend generally parallel to the longitudinal axis L of the cable 130. These beveled surfaces are configured such that, in a connection configuration, a lateral force is applied to the connector as the additional beveled peripheral surfaces 140 move relative to each other (see [link to connector configuration]). Figure 6 The arrow S (i.e., the force not aligned with the longitudinal axis L of cable 130) will cause the first connector 102 and the second connector 104 to disconnect.

[0060] The fourth and final outer peripheral wall 142 of the protrusion 114 and the recess 124 is generally perpendicular to surfaces 110 and 122, i.e., surface 142 is not inclined. Therefore, the protrusion and the recess have only one degree of rotational symmetry (as in...). Figure 6 (As can be observed in the image), this allows connectors 102 and 104 to connect only in one orientation. This ensures that contacts 106 and 108 are always correctly paired.

[0061] Turn now Figure 7 An alternative example of the second connector 204 is shown. In this example, connector 204 includes a connector portion 205 on which complementary recesses 224 are arranged in a manner similar to that described above for connector 104. Connector portion 205 is substantially flat or planar, taking the form of a flat cuboid. In this example, connector 204 also includes a stepped portion 207 and a cable portion 209 that positions a connection interface 232 between cable 230 and connector 204. Stepped portion 207 is inclined relative to connector portion 205, such that the cable is spaced apart from connector portion 205. Therefore, cable 230 intersects connector 204 at a location that is more spaced apart from another connector (e.g., first connector 102) than connector portion 205.

[0062] This configuration may cause the tension applied to the cable 230 to also apply a disintegration tilting force to the connector portion 205, which may also help to lift the second connector 204 away from the first connector 102.

[0063] like Figure 8 and Figure 9 As shown, the second connector 204 includes a cover 210 configured to cover the connection surfaces of each of the connector portion 205, the stepped portion 207, and the cable portion 209. The cover 210 includes an elastomeric material layer 212 and two magnetic elements 214 attached to the elastomeric layer 212. Figure 9 (As shown). The magnetic element 214 is made of an ferrous metal (such as steel). The magnetic element 214 is configured to cover the magnet 228 and be attracted to the magnet 228 so that when the second connector 204 is not in use (e.g. Figure 8 (As shown) Keep cover 210 in place.

[0064] Cover 210 is hingedly attached to the second connector 204 at cable portion 209 for pivoting about the hinged cable H. Cover 210 also includes a pull tab 216. By lifting the pull tab 216, the magnet 228 of connector portion 205 can be exposed (e.g., Figure 9 As shown in the figure, that is, when it is desired to attach the second connector 204 to the first connector 102.

[0065] When the second connector 204 is not in use, the cover 210 prevents accidental attachment between the magnet 228 of the second connector 104 and ferrous metal objects. It will be understood that the corresponding cover 210 can be used with the second connector 104 described above.

[0066] Another aspect of the connector system 100 will now be described.

[0067] The foregoing has described a first connector including a protrusion 114 and a second connector including a complementaryly shaped recess 124 for receiving the protrusion, which is rotationally asymmetrical to limit the connection of connectors 102, 104 in a single orientation. To further prevent connection of connectors 102, 104 in incorrect orientation, the first connector 102 includes an additional protrusion 144, and the second connector 104 includes an additional complementary recess 146 for receiving the protrusion 144 in a connected configuration. By providing multiple protrusions 114, 144 and multiple complementary recesses 124, 146, incorrect connection of the connectors can be avoided because, in incorrect orientation, the protrusion 144 would contact the surface 122 of the second connector 104 and prevent the connectors from properly engaging so that the magnet 128 can be securely connected. It should be understood that, generally, the geometry of the protrusions and complementary recesses ensures that contacts 106 and 108 will not contact unless the connectors are connected in the correct orientation.

[0068] In this example, the additional protrusions 144 and complementary recesses 146 are substantially truncated conical in shape, such that lateral forces in any direction in the plane of the connector (i.e., transverse to the direction of extension of the protrusion) will generate a lifting force that will cause the connector to separate. It should be understood that protrusions and recesses including contacts are “contact protrusions” and “contact recesses,” and other protrusions and recesses may be positioning protrusions and recesses that do not include contacts.

[0069] To avoid unnecessary repetition and redundant wording in this specification, certain features are described only with respect to one or more aspects or embodiments of the invention. However, it should be understood that, where technically possible, the features described with respect to any aspect or embodiment of the invention may also be used with respect to any other aspect or embodiment of the invention.

[0070] Those skilled in the art will understand that although the invention has been described by way of example with reference to one or more exemplary examples, it is not limited to the disclosed examples, and alternative examples can be constructed without departing from the scope of the invention as defined by the appended claims.

[0071] For example, the detailed description above illustrates a specific configuration of the connection system in which a protruding element is provided on a connector located on a backplane, while a recess is provided on another connector. In other instances, the recess can be provided on the backplane connector, while the other connector includes a protrusion. In still other instances, the connectors can each have recesses and protrusions that are complementary to the corresponding protrusions and recesses on the other connector.
