Abstract
Description
TERMINAL ADAPTORFIELD
[0001] The present disclosure relates to a terminal adaptor connectable to a battery, a battery assembly and a kit of parts each comprising the terminal adaptor and the battery, and an aerosol generating apparatus.BACKGROUND
[0002] A typical aerosol generating apparatus may comprise a power supply such as a battery, an aerosol generating unit that is driven by the power supply, an aerosol precursor, which in use is aerosolised by the aerosol generating unit to generate an aerosol, and a delivery system for delivery of the aerosol to a user. The aerosol generating apparatus may comprise a battery chamber for receiving and electrically connecting to the battery. The battery may comprise a positive battery terminal and a negative battery terminal both located on the same end face of the battery.
[0003] A drawback with known aerosol generating apparatuses having batteries of this kind is the need for precise rotational alignment of the battery terminals inside the battery chamber so that electric connection can be established between the battery terminals and electric contacts provided inside the battery chamber. This can complicate battery insertion into the aerosol generating apparatus, thereby hindering manufacturability and / or user experience of the aerosol generating apparatus.
[0004] A further drawback of using a battery with both battery terminals located on the same end face is the risk of an electrical short circuit when disposing of the battery. Specifically, when the positive and negative battery terminals are provided on the same plane, a flat piece of electric conductor such as metal can easily short circuit the electrodes of the battery and lead to battery fire during disposal.
[0005] In spite of the effort already invested in the development of aerosol generating apparatuses / systems further improvements are desirable.SUMMARY
[0006] In a first aspect, there is provided a terminal adaptor connectable to a battery, the battery comprising a positive battery terminal and a negative battery terminal each located on a first end face of the battery, wherein the terminal adaptor comprises:
[0007] an abutment face configured to abut the first end face of the battery in use;
[0008] a terminal face opposite the abutment face, the terminal face comprising a positive terminal region and a negative terminal region electrically insulated from the positive terminal region, the positive terminal region being electrically connectable to the positive battery terminal and the negative terminal region being electrically connectable to the negative battery terminal; and
[0009] an insulating element interposed between the positive terminal region and the negative terminal region to electrically insulate the positive terminal region from the negative terminal region.
[0010] In some examples, the insulating element abuts and upstands from the terminal face.
[0011] By providing an insulating element (i.e. an electrically insulating element) that abuts and upstands from the terminal face (on which the terminal regions are formed) , the insulating element can ensure that a planar contact (e.g. a planar electric conductor) cannot simultaneously contact both the positive terminal region and the negative terminal region, thereby reducing a risk of electrical short circuit, e.g. after disposal of the battery.
[0012] The insulating element has a mounting face which rests against i.e. abut the terminal face of the insulating element.
[0013] In some examples, the insulating element may upstand from the terminal face by at least 0.5mm, or at least 0.75mm, or at least 1mm, or at least 1.25mm, or at least 1.5mm such as around 1.5mm.
[0014] In some examples, the insulating element may be formed of a substantially rigid material. In this way, the insulating element can resist compressive forces applied thereto to ensure that a planar contact cannot simultaneously contact both the positive terminal region and the negative terminal region even when pressed onto the insulating element, towards the terminal face.
[0015] The insulating element may be formed of a material having a compressive strength of at least 50 MPa, or at least 60 MPa, or at least 70 MPa, or at least 80 MPa such as around 80 MPa. The compressive strength is the value of uniaxial compressive stress, σ, at which the material fails.
[0016] The insulating element may be formed of a material having a maximum deformation of 10%or less, or 7%or less, or 5%or less, or 1%or less when subjected to compressive stress having a magnitude equal to or less than an absolute value of σ.
[0017] In some examples, the insulating element may be formed of plastic such as a thermoplastic polymer e.g. a polycarbonate (PC) .
[0018] In some examples, the insulating element may be provided with adhesive for adhering to the terminal face of the terminal adaptor. For example, the mounting surface of the insulating element may be coated with a layer of adhesive. The mounting surface of the insulating element comprising the adhesive is the surface configured for contact with the terminal face of the terminal adaptor.
[0019] In some examples, the terminal adaptor may comprise a pair of through holes each extending at least partially from the abutment face to the terminal face, wherein each of the pair of through holes is configured to receive a respective one of the positive battery terminal and the negative battery terminal. That is, the pair of through holes may at least partially extend through the terminal adaptor in the thickness direction. In this way, the terminal adaptor can be mounted to the first end face of the battery by inserting the first battery terminal into one through holes and inserting the negative battery terminal into the other through hole.
[0020] In some examples, each or both of the through holes may extend entirely through the terminal adaptor in the thickness direction such that each or both of the through holes has respective openings in both the abutment face and the terminal face. The length of each through hole (i.e. along the thickness direction) may match a length of each battery terminal such that when each battery terminal is inserted into a respective one of the through holes it does not protrude above the terminal face of the terminal adaptor, but is instead flush with the terminal face. The location of each through hole on the terminal face may be between the positive terminal region and the negative terminal region along the radial direction. The through holes may be diametrically opposed to one another.
[0021] The insulating element may abut the terminal face such that the insulating element covers (i.e. blocks / overlies) openings of the through holes at the terminal face. Thus, in use, the insulating element may cover the positive and negative battery terminals at the terminal face of the adaptor.
[0022] In some examples, each of the positive terminal region and the negative terminal region may be rotationally symmetrically arranged on the terminal face. In this way, when connected to the battery, the terminal adaptor can in effect re-configure the battery terminals such that there is a plurality of rotational orientations of the battery relative to its axial direction in which an electrical connection can be established in use between the terminal regions and electric contacts e.g. inside an aerosol generating apparatus. Thus, the need for precise rotational alignment of the positive / negative terminal regions relative to the electric contacts is eliminated.
[0023] In some examples, the positive terminal region may have a degree of rotational symmetry, n, which is at least 2, or at least 3, or at least 4, or at least 5, or at least 6. The degree of rotational symmetry, n, is the number of times that the terminal region can be rotated within 360 degrees and display rotational symmetry. Similarly, the negative terminal region may have a degree of rotational symmetry, n, which is at least 2, or at least 3, or at least 4, or at least 5, or at least 6.
[0024] In some examples, each of the positive terminal region and the negative terminal region may be circularly symmetrically arranged on the terminal face. In this way, each of the positive terminal region and the negative terminal region can be rotationally symmetrical with respect to any angle. This allows electrical connection to be established between the battery terminals (via the terminal regions) and electric contacts of e.g. an aerosol generating apparatus in any rotational orientation of the battery.
[0025] In some examples, one of the positive terminal region and the negative terminal region may be a radially outer terminal region, and the other of the positive terminal region and the negative terminal region may be a radially inner terminal region. When the radially outer terminal region is circularly symmetrical, it may be an annulus in the plane of the terminal face. When the radially inner terminal region is circularly symmetrical, it may be a circle or an annulus in the plane of the terminal face. The radially inner terminal region may be the positive terminal region and the radially outer terminal region may be the negative terminal region. Alternatively, the radially inner terminal region may be the negative terminal region and the radially outer terminal region may be the positive terminal region.
[0026] The insulating element may be provided radially inwardly of the radially outer terminal region. The insulating element may be provided radially outwardly of the radially inner terminal region. The insulating element may extend fully between the radially outer terminal region and the radially inner terminal region in the radial direction on the terminal face.
[0027] In some examples, the insulating element may be an annulus such that the insulating element forms a ring in the plane of the terminal face, e.g. when each of the positive and the negative terminal region is circularly symmetrical. Thus, the annular insulating element defines a central opening. The central opening of the insulating element may overlie the radially inner terminal region e.g. so as to expose it for electric connection to an electric contact. That is, the insulating element may circumscribe the radially inner terminal region.
[0028] In some examples, a portion of the insulating element proximal the mounting surface may be recessed into the terminal adaptor. That is, the insulating element may at least partially extend along the thickness direction between the terminal face and the abutment face. In this way, the insulating element may electrically insulate layers within the terminal adaptor, such as electrically conductive layers within the terminal adaptor.
[0029] In some examples, the positive terminal region may be electrically connectable to the positive battery terminal via a first electrical connection and the negative terminal region may be electrically connectable to the negative battery terminal via a second electrical connection. Each of the first electrical connection and the second electrical connection may be internal to the terminal adaptor. That is, each of the first electrical connection and the second electrical connection may be located between the terminal face and the abutment face of the terminal adaptor, such that each of the first electrical connection and the second electrical connection is completely enclosed within the terminal adaptor.
[0030] As discussed above, the terminal adaptor may comprise at least one electrically conductive layer. The first electrical connection configured to electrically connect the positive battery terminal to the positive terminal region may comprise a first electrically conductive layer. The second electrical connection configured to electrically connect the negative battery terminal to the negative terminal region may comprise a second electrically conductive layer, and the negative battery terminal to the negative terminal region. The terminal adaptor may be a printed circuit board.
[0031] In a second aspect, the present disclosure provides a battery assembly comprising:
[0032] a battery having a positive battery terminal and a negative battery terminal each located on a first end face of the battery; and
[0033] the terminal adaptor according to the first aspect, the terminal adaptor being mounted on the first end face of the battery.
[0034] In some examples, each of the positive battery terminal and the negative battery terminal may be an elongated battery terminal axially extending away from the first end face. That is, the battery terminals may be provided as pins (or prongs) extending from the first end face of the battery.
[0035] In some examples, each of the positive battery terminal and the negative battery terminal may be soldered to the terminal adaptor, e.g. to the terminal face of the terminal adaptor.
[0036] In some examples, each of the positive battery terminal and the negative battery terminal may be flush (i.e. coplanar) with the terminal face. That is, each of the positive battery terminal and the negative battery terminal may be coplanar with the positive terminal region and the negative terminal region. This may be achieved by cutting the battery terminals as described in more detail below.
[0037] The insulating element may abut the terminal face such that the insulating element covers (i.e. blocks) openings of the through holes at the terminal face. That is, the insulating element may abut the terminal face such that the insulating element covers (i.e. sits over) the positive battery terminal and the negative battery terminal at the terminal face.
[0038] In some examples, the battery and the terminal adaptor may be integral such that the battery assembly provides a unitary battery component.
[0039] In a third aspect, the present disclosure provides an aerosol generating apparatus comprising the terminal adaptor according to the first aspect or the battery assembly according to the second aspect.
[0040] In some examples, the aerosol generating apparatus may comprise a battery chamber for receiving the battery assembly. The battery chamber may comprise a pair of electric contacts each connectable to a respective one of the positive terminal region and the negative terminal region on the terminal face of the terminal adaptor. The electric contacts may be both located at an upper axial end of the battery chamber, proximal a heating element of the aerosol generating apparatus. Either or both of the electric contacts may be a sprung electric contact resiliently biased into the battery chamber. Either or both of the electric contacts may have a substantially serpentine-shaped cross section in a plane extending along the axial direction of the aerosol generating apparatus.
[0041] In a fourth aspect, the present disclosure provides a kit of parts comprising:
[0042] a battery comprising a positive battery terminal and a negative battery terminal each located on a first end face of the battery; and
[0043] the terminal adaptor according to the first aspect.
[0044] When the terminal adaptor comprises the insulating element, the kit of parts may comprise the insulating element separately to the terminal adaptor.
[0045] In a fifth aspect, the present disclosure provides a method of forming the battery assembly of the second aspect, the method comprising:
[0046] providing the battery;
[0047] providing a terminal adaptor according to the first aspect;
[0048] mounting the terminal adaptor on the first end face of the battery such that the abutment face of the terminal adaptor abuts the first end face of the battery,
[0049] wherein mounting the terminal adaptor on the first end face of the battery includes electrically connecting the positive terminal region of the terminal adaptor to the positive battery terminal and connecting the negative terminal region of the terminal adaptor to the negative battery terminal; and
[0050] mounting the insulating element in abutment with the terminal face of the terminal adaptor.
[0051] In some examples, providing the terminal adaptor of the first aspect may include providing a terminal adaptor pre-cursor and forming the terminal adaptor according to the first aspect from the terminal adaptor pre-cursor.
[0052] The terminal adaptor pre-cursor may comprise the abutment face and the terminal face opposite the abutment face, the terminal face comprising the positive terminal region electrically connectable to the positive battery terminal and the negative terminal region electrically connectable to the negative battery terminal, wherein the positive terminal region is electrically insulated from the negative terminal region.
[0053] Each of the positive terminal region and the negative terminal region may be rotationally (e.g. circularly) symmetrically arranged on the terminal face. The terminal adaptor pre-cursor may be a printed circuit board. The terminal adaptor pre-cursor may comprise at least one electrically conductive layer configured to electrically connect the positive battery terminal to the positive terminal region, and the negative battery terminal to the negative terminal region. The at least one electrically conductive layer may comprise a first electrically conductive layer and a second electrically conductive layer, the first electrically conductive layer being configured to electrically connect the positive battery terminal to the positive terminal region, and the second electrically conductive layer being configured to electrically connect the negative battery terminal to the negative terminal region.
[0054] Forming the terminal adaptor of the first aspect from the terminal adaptor pre-cursor may comprise forming the pair of through holes in the terminal adaptor pre-cursor such that each through hole extends at least partially from the abutment face to the terminal face. For example, forming the pair of through holes may include drilling the pair of through holes into the terminal adaptor pre-cursor in the thickness direction, from the abutment face or from the terminal face.
[0055] In some examples, mounting the terminal adaptor on the first end face of the battery may include securing each of the positive and negative battery terminals to the terminal adaptor, e.g. to the terminal face of the terminal adaptor. Securing each of the battery terminals to the terminal adaptor may include welding (e.g. laser welding) and / or soldering each of the battery terminals to the terminal adaptor (e.g. to the terminal face of the terminal adaptor) . This step may be performed after inserting each of the positive battery terminal and the negative battery terminal into a respective one of the pair of through holes. When the battery terminals are soldered to the terminal adaptor, the terminal face may comprise one or more solder pads, the / each solder pad being configured for soldering of the positive battery terminal and / or the negative battery terminal thereto.
[0056] When the positive and negative battery terminals each have a longer axial length than the thickness of the terminal adaptor (and / or than the axial length of the through holes) , the method may include cutting each of the positive battery terminal and the negative battery terminal so as to be flush with the terminal face. This step may be performed after soldering / welding the battery terminals to the terminal adaptor.
[0057] In some examples, mounting the insulating element may include positioning the insulating element on the terminal face of the terminal adaptor, e.g. so as to cover openings of the through holes and / or the battery terminals at the terminal face. Mounting the insulating element may further include pressing the insulating element onto the terminal face terminal adaptor such that an adhesive-coated surface of the insulating element contacts and adheres to a surface on the terminal face of the terminal adaptor.
[0058] In some examples, mounting the insulating element may be performed after mounting the terminal adaptor on the first end face of the battery. For example, the insulating element may be mounted on the terminal adaptor after the battery terminals are electrically connected to the terminal regions on the terminal adaptor and / or after the battery terminals are soldered to the terminal face and / or after the battery terminals are cut so as to be flush with the terminal face.

In a heat-not-burn consumable, the mouthpiece may be implemented as a filter and the consumable may be arranged to carry the precursor. The consumable may be implemented as a dosage or pre-portioned amount of material, including a loose-leaf product.

[0096] Referring to Fig. 1, an example aerosol generating apparatus 1 includes a power supply 2, for supply of electrical energy. The apparatus 1 includes an aerosol generating unit 4 that is driven by the power supply 2. The power supply 2 includes an electric power supply in the form of a battery. The apparatus 1 includes a precursor 6, which in use is aerosolised by the aerosol generating unit 4 to generate an aerosol. The apparatus 2 includes a delivery system 8 for delivery of the aerosol to a user.
[0097] Electrical circuitry (not shown in Fig. 1) may be implemented to control the interoperability of the power supply 2 and aerosol generating unit 4.
[0098] Fig. 2 shows an implementation of the apparatus 1 of Fig. 1, where the aerosol generating apparatus 1 is configured to generate aerosol from a liquid precursor.
[0099] In this example, the apparatus 1 includes a device body 10 and a consumable 30.
[0100] In this example, the body 10 includes the power supply 2. The body may additionally include any one or more of electrical circuitry 12, a memory 14, a wireless interface 16, one or more other components 18.
[0101] The electrical circuitry 12 may include a processing resource for controlling one or more operations of the body 10 and consumable 30, e.g. based on instructions stored in the memory 14.
[0102] The wireless interface 16 may be configured to communicate wirelessly with an external (e.g. mobile) device, e.g. via Bluetooth.
[0103] The other component (s) 18 may include one or more user interface devices configured to convey information to a user and / or a charging port, for example (see e.g. Fig. 3) .
[0104] The consumable 30 includes a storage portion implemented here as a tank 32 which stores the liquid precursor 6 (e.g. e-liquid) . The consumable 30 also includes a heating system 34, one or more air inlets 36, and a mouthpiece 38. The consumable 30 may include one or more other components 40.
[0105] The body 10 and consumable 30 may each include a respective electrical interface (not shown) to provide an electrical connection between one or more components of the body 10 with one or more components of the consumable 30. In this way, electrical power can be supplied to components (e.g. the heating system 34) of the consumable 30, without the consumable 30 needing to have its own power supply.
[0106] In use, a user may activate the aerosol generating apparatus 1 when inhaling through the mouthpiece 38, i.e. when performing a puff. The puff, performed by the user, may initiate a flow through a flow path in the consumable 30 which extends from the air inlet (s) 34 to the mouthpiece 38 via a region in proximity to the heating system 34.
[0107] Activation of the aerosol generating apparatus 1 may be initiated, for example, by an airflow sensor in the body 10 which detects airflow in the aerosol generating apparatus 1 (e.g. caused by a user inhaling through the mouthpiece) , or by actuation of an actuator included in the body 10. Upon activation, the electrical circuitry 12 (e.g. under control of the processing resource) may supply electrical energy from the power supply 2 to the heating system 34 which may cause the heating system 32 to heat liquid precursor 6 drawn from the tank to produce an aerosol which is carried by the flow out of the mouthpiece 38.
[0108] In some examples, the heating system 34 may include a heating filament and a wick, wherein a first portion of the wick extends into the tank 32 in order to draw liquid precursor 6 out from the tank 32, wherein the heating filament coils around a second portion of the wick located outside the tank 32. The heating filament may be configured to heat up liquid precursor 6 drawn out of the tank 32 by the wick to produce the aerosol.
[0109] In this example, the aerosol generating unit 4 is provided by the above-described heating system 34 and the delivery system 8 is provided by the above-described flow path and mouthpiece 38.
[0110] In variant embodiments (not shown) , any one or more of the precursor 6, heating system 34, air inlet (s) 36 and mouthpiece 38, may be included in the body 10. For example, the mouthpiece 36 may be included in the body 10 with the precursor 6 and heating system 32 arranged as a separable cartomizer. Figs. 3A and 3B show an example implementation of the aerosol generating device 1 of Fig. 2. In this example, the consumable 30 is implemented as a capsule / pod, which is shown in Fig. 3A as being physically coupled to the body 10, and is shown in Fig. 3B as being decoupled from the body 10.
[0111] In this example, the body 10 and the consumable 30 are configured to be physically coupled together by pushing the consumable 30 into an aperture in a top end 11 the body 10, with the consumable 30 being retained in the aperture via an interference fit.
[0112] In other examples (not shown) , the body 10 and the consumable 30 could be physically coupled together in other ways, e.g. by screwing one onto the other, through a bayonet fitting, or through a snap engagement mechanism, for example.
[0113] The body 10 also includes a charging port (not shown) at a bottom end 13 of the body 10.
[0114] The body 10 also includes a user interface device configured to convey information to a user. Here, the user interface device is implemented as a light 15, which may e.g. be configured to illuminate when the apparatus 1 is activated. Other user interface devices are possible, e.g. to convey information haptically or audibly to a user.
[0115] In this example, the consumable 30 has an opaque cap 31, a translucent tank 32 and a translucent window 33. When the consumable 30 is physically coupled to the body 10 as shown in Fig. 3A, only the cap 31 and window 33 can be seen, with the tank 32 being obscured from view by the body 10. The body 10 includes a slot 15 to accommodate the window 33. The window 33 is configured to allow the amount of liquid precursor 6 in the tank 32 to be visually assessed, even when the consumable 30 is physically coupled to the body 10.
[0116] Fig. 4 shows an implementation of the apparatus 1 of Fig. 1, where the aerosol generating apparatus 1 is configured to generate aerosol by a-heat not-burn process.
[0117] In this example, the apparatus 1 includes a device body 50 and a consumable 70.
[0118] In this example, the body 50 includes the power supply 2 and a heating system 52. The heating system 54 includes at least one heating element 54. The body may additionally include any one or more of electrical circuitry 56, a memory 58, a wireless interface 60, one or more other components 62.
[0119] The electrical circuitry 56 may include a processing resource for controlling one or more operations of the body 50, e.g. based on instructions stored in the memory 58.
[0120] The wireless interface 60 may be configured to communicate wirelessly with an external (e.g. mobile) device, e.g. via Bluetooth.
[0121] The other component (s) 62 may include an actuator, one or more user interface devices configured to convey information to a user and / or a charging port, for example (see e.g. Fig. 5) .
[0122] The body 50 is configured to engage with the consumable 70 such that the at least one heating element 54 of the heating system 52 penetrates into the solid precursor 6 of the consumable. In use, a user may activate the aerosol generating apparatus 1 to cause the heating system 52 of the body 50 to cause the at least one heating element 54 to heat the solid precursor 6 of the consumable (without combusting it) by conductive heat transfer, to generate an aerosol which is inhaled by the user.
[0123] Fig. 5 shows an example implementation of the aerosol generating device 1 of Fig. 4.
[0124] As depicted in Fig. 5, the consumable 70 is implemented as a stick, which is engaged with the body 50 by inserting the stick into an aperture at a top end 53 of the body 50, which causes the at least one heating element 54 of the heating system 52 to penetrate into the solid precursor 6.
[0125] The consumable 70 includes the solid precursor 6 proximal to the body 50, and a filter distal to the body 50.The filter serves as the mouthpiece of the consumable 70 and thus the apparatus 1 as a whole. The solid precursor 6 may be a reconstituted tobacco formulation.
[0126] In this example, the at least one heating element 54 is a rod-shaped element with a circular transverse profile. Other heating element shapes are possible, e.g. the at least one heating element may be blade-shaped (with a rectangular transverse profile) or tube-shaped (e.g. with a hollow transverse profile) .
[0127] In this example, the body 50 includes a cap 51. In use the cap 51 is engaged at a top end 53 of the body 50. Although not apparent from Fig. 5, the cap 51 is moveable relative to the body 50. In particular, the cap 51 is slidable and can slide along a longitudinal axis of the body 50.
[0128] The body 50 also includes an actuator 55 on an outer surface of the body 50. In this example, the actuator 55 has the form of a button.
[0129] The body 50 also includes a user interface device configured to convey information to a user. Here, the user interface device is implemented as a plurality of lights 57, which may e.g. be configured to illuminate when the apparatus 1 is activated and / or to indicate a charging state of the power supply 2. Other user interface devices are possible, e.g. to convey information haptically or audibly to a user.
[0130] The body may also include an airflow sensor which detects airflow in the aerosol generating apparatus 1 (e.g. caused by a user inhaling through the consumable 70) . This may be used to count puffs, for example.
[0131] In this example, the consumable 70 includes a flow path which transmits aerosol generated by the at least one heating element 54 to the mouthpiece of the consumable.
[0132] In this example, the aerosol generating unit 4 is provided by the above-described heating system 52 and the delivery system 8 is provided by the above-described flow path and mouthpiece of the consumable 70.
[0133] Next, an aerosol generating system, which may be implemented in any of the preceding examples, can comprise a battery assembly 200 as discussed with reference to Figs 6A-6D. The battery assembly 200 comprises a terminal adaptor 100 and the battery 2. The battery 2 comprises a positive battery terminal 103 and a negative battery terminal 104 each located on a first end face 23 of the battery 2. Each of the positive battery terminal 21 and the negative battery terminal 22 is provided as respective a pin (prong) extending from the first end face 23 of the battery 2. The positive 21 and negative 22 battery terminals are diametrically opposed to one another.
[0134] The terminal adaptor 100 comprises an abutment face 101 configured to abut the first end face 23 of the battery 2 and a terminal face 102 opposite the abutment face. The terminal face 102 comprises a positive terminal region 103 and a negative terminal region 104 electrically insulated from the positive terminal region 103. The positive terminal region 103 is electrically connectable to the positive battery terminal 21 and the negative terminal region 104 is electrically connectable to the negative battery terminal 22. Each of the positive terminal region 103 and the negative terminal region 104 is rotationally symmetrically arranged on the terminal face 102. Specifically, in the example of Figs 6A-11 each of the positive terminal region 103 and the negative terminal region 104 is circularly symmetrically arranged on the terminal face 102.
[0135] In these examples, the negative terminal region 104 is a radially outer terminal region, and the positive terminal region 103 is a radially inner terminal region. Thus, the negative terminal region 104 is an annulus in the plane of terminal face 102, whereas the positive terminal region 103 is a circle in the plane of the terminal face 102. However, it is also envisaged that the negative terminal region 104 may be the radially inner terminal region and the positive terminal region 103 may be the radially outer terminal region in an alternative configuration of the terminal connector 100.
[0136] In these examples, the positive terminal region 103 is co-planar with the negative terminal region 104 such that the terminal face 102 is planar.
[0137] With specific reference to any one of Figs 6A and 6B, the terminal adaptor 100 further comprises a pair of through holes 106 each extending fully from the abutment face 101 to the terminal face 102. To mount the terminal adaptor 100 on the battery 2, each of the positive 21 and the negative 22 battery terminals is inserted into a respective one of the through holes 106. The location of each through hole 106 on the terminal face 102 is between the positive terminal region 103 and the negative terminal region 104 along the radial direction. The through holes 106 are diametrically opposed to one another relative to the positive terminal region 103. The insulation element 105 abuts the terminal face 102 such that the insulating element covers openings of the through holes as well as the positive 21 and negative 22 battery terminals at the terminal face. That is, the insulating element 105 sits over the openings of the through holes 106 and the battery terminals 21, 22 at the terminal face 102.
[0138] The terminal adaptor is a printed circuit board (PCB) comprising a first electrically conductive layer and a second electrically conductive layer (not shown) . The electrically conductive layers are spaced from one another by electrically insulating layers such as dielectric / prepreg layers. The first electrically conductive layer is configured to electrically connect the positive battery terminal 21 to the positive terminal region 103, and the second electrically conductive layer is configured to electrically connect the negative battery terminal 22 to the negative terminal region 104.
[0139] With reference to Fig. 6B, it is possible that the positive 21 and negative 22 battery terminals each have a longer axial length than the thickness of the terminal 100 such that, after insertion into the through holes 106, the battery terminals 21, 22 protrude away from the battery face 102. In this example, the battery terminals 21, 22 are then cut flush with the terminal face 102 to obtain the arrangement shown in Fig. 6C. Each of the positive battery terminal 21 and the negative battery terminal 22 is soldered to the terminal face 102 at respective solder pads 109 provided around the through holes 106. Additionally, or alternatively, to mount the terminal adaptor 100 on the battery 2, each of the positive 21 and negative 22 battery terminals can be welded (e.g. laser welded) to the terminal adaptor 100. Soldering and / or welding the battery terminals 21, 22 to the terminal adaptor 100 (e.g. to the terminal face 102) can be performed before or after cutting the battery terminals flush with the terminal face 102.
[0140] With reference to Figs 6A and 6D, the terminal face 102 comprises an insulating element 105 interposed between the positive terminal region 103 and the negative terminal region 104 to electrically insulate the positive terminal region from the negative terminal region. The insulating element 105 is an annulus in the plane of the terminal face 102. The insulating element is provided radially inwardly of the radially outer (i.e. the negative) terminal region 104. The insulating element is provided radially outwardly of the radially inner (i.e. the positive) terminal region 103. That is, the insulating element 105 circumscribes the positive terminal region 103. The insulating element 105 defines a central opening overlying the positive terminal region e.g. so as to expose it for electric connection to an electric contact (see Fig. 8) . The insulating element 105 abuts the terminal face 102 of the terminal adaptor 100 (i.e. such that it does not extend between the terminal face and the abutment face but merely rests against the terminal face 102) .
[0141] The insulating element 105 upstands from the terminal face 102. In this way, the insulating element ensures that a planar contact (e.g. a planar electric conductor) cannot simultaneously contact both the positive terminal region 103 and the negative terminal region 104, thereby reducing a risk of electrical short circuit, e.g. after disposal of the battery. In this example, the insulating element upstands from the terminal face by 1.5mm. In this example, the insulating element is formed of a polycarbonate (PC) having a compressive strength of around 80 MPa with 10%or less deformation. Thus, the insulating element 105 is substantially rigid such that it can resist compressive forces applied thereto to ensure that a planar contact cannot simultaneously contact both the positive terminal region 103 and the negative terminal region 104 even when pressed onto the insulating element 105, towards the terminal face 102.
[0142] In the example of Figs 6A-6D, the insulating element 105 is provided with adhesive for adhering to the terminal adaptor 100. That is, a surface of the insulating element 105 is coated with a layer of adhesive. Thus, to mount the insulating element 105 on the terminal adaptor 100 the insulating element is pressed onto the terminal face 102 of the terminal adaptor 100 such that the adhesive-coated surface of the insulating element 105 contacts and adheres to the terminal face 102.
[0143] Mounting the insulating element 105 is performed after mounting the terminal adaptor 100 on the first end face 23 of the battery 2, after the battery terminals 21, 22 are electrically connected to the terminal regions 103, 104 on the terminal adaptor 100, after the battery terminals are soldered to the terminal face 102, and after the battery terminals are cut so as to be flush with the terminal face.
[0144] The assembled configuration of the battery assembly 200 is shown in Fig. 6D.
[0145] With reference to Figs 7A and 7B, the battery 2 and the terminal adaptor 100 can be integral such that the battery assembly 200 provides a unitary battery component. In this variant, a portion of the insulating element 105 is provided within the terminal adaptor 100. That is, the insulating element 105 partially extends along a thickness direction between the terminal face 102 and the abutment face 101. In this way, the insulating element 105 can electrically insulate layers within the terminal adaptor 100, such as electrically conductive layers within the terminal adaptor.
[0146] Both variants of the battery assembly 200 (i.e. that of Figs 6A-D and that of Figs 7A-7B) have an advantageous effect of eliminating the need for precise rotational alignment of the positive / negative terminal regions 103, 104 relative to electric contacts 302 of an aerosol generating apparatus 300 (shown in Figs 9 and 10) . Specifically, because the positive terminal region 103 and the negative terminal region 104 are circularly symmetrically arranged on the terminal face 102, both terminal regions are rotationally symmetrical with respect to any angle which allows an electrical connection to be established between the battery terminals 21, 22 (via the terminal regions 103, 104) and electric contacts 302 of the aerosol generating apparatus in any rotational orientation of the battery assembly 200.
[0147] This is illustrated in Fig. 8 where any rotational orientation of the battery assembly 200 relative to the positive electric contact 302a results in an electric connection between the positive terminal region 103 and the positive electric contact 302a. Similarly, any rotational orientation of the battery assembly 200 relative to the negative electric contact 302b results in an electric connection between the negative terminal region 104 and the negative electric contact 302b.
[0148] With reference to Figs 9 and 10 the battery assembly 200 can be mounted inside an aerosol generating apparatus 300 implemented according to any of the examples discussed above. The aerosol generating apparatus 300 comprises a battery chamber 301 for receiving and electrically connecting to the battery assembly 200. The battery chamber 301 comprises a pair of electric contacts 302 (comprising a positive electric contact 302a and a negative electric contact 302b) each connectable to a respective one of the positive terminal region 103 and the negative terminal region 104 on the terminal face 102 of the terminal adaptor 100. The electric contacts 302 are both located at an upper axial end of the battery chamber 301, proximal the heating element 54 of the aerosol generating apparatus 300. Both electric contacts 302 are sprung electric contacts resiliently biased into the battery chamber 301. Each of the electric contacts 302 has a substantially serpentine-shaped cross section in a plane extending along the axial direction of the aerosol generating apparatus 300 (not shown in Fig. 9) . As shown in Fig. 9, the battery assembly 200 is inserted into the battery chamber 301 such that the terminal regions 103, 104 electrically connect to the electric contacts 302 at the upper axial end of the battery chamber. The lower end of the battery chamber 301 is closed off by a cap assembly 303. The assembled configuration of the aerosol generating apparatus 300 comprising the battery assembly 200 is shown in Fig. 10.
