[Technical Field]
[0001] TECHNICAL FIELD This application relates to terminal connectors, and more particularly to terminal connectors with terminal posts and caps. [Background technology]
[0002] Vibrating conduit sensors, such as Coriolis mass flowmeters and vibrating densitometers, typically operate by vibrating one or more conduits in the presence of a fluid and then detecting the movement of the one or more vibrating conduits. For example, Figures 1A and 1B show an example of a Coriolis flowmeter 100. Figure 1A shows a front view of Coriolis flowmeter 100 with the top of the case cut off, and Figure 1B shows a side view of Coriolis flowmeter 100 without the case.
[0003] The exemplary Coriolis flowmeter 100 includes a case 102, conduits 104, 106, manifolds 108, 110, and a spacer 112. Fluid enters through an inlet and passes through the manifold 108, which splits the fluid into U-shaped conduits 104, 106. After passing through the conduits, the fluid eventually recombines through manifold 110 and exits the flowmeter through an outlet.
[0004] Coriolis flowmeter 100 further includes a driver 114 and pickoffs 116 and 118. Driver 114 and pickoffs 116 and 118 each include a coil and a magnetic component. In the exemplary embodiment of Coriolis flowmeter 100, the coil and magnetic components of driver 114 and pickoffs 116 and 118 are coupled to adjacent, opposing conduits 104 and 106, respectively. Driver 114 is positioned substantially centrally along the axial length of conduits 104 and 106, and pickoffs 116 and 118 are positioned on opposite sides of driver 114. Driver 114 vibrates the flow tubes in opposite directions, and pickoffs 116 and 118 detect a phase difference or twist of the flowmeter due to the Coriolis effect that occurs when the flowing fluid is vibrated by driver 114. The phase difference measured via pickoffs 116 and 118 can be used to determine mass flow or volumetric flow measurements. Alternatively, as will be appreciated by those skilled in the art, the frequency determined via either pickoff 116 or 118 can be used to determine the density of the fluid being measured.
[0005] Those skilled in the art will appreciate that Coriolis flowmeter 100 is merely one example of a vibrating conduit sensor. In other embodiments, the Coriolis flowmeter may have a single flow tube, and portions of driver 114 and pickoffs 116, 118 may be coupled to a support instead of the opposing flow tube. In further embodiments, the Coriolis flowmeter may have three or more flow tubes, and driver 114 and pickoffs 116, 118 may be coupled to any combination of flow tubes and supports. Those skilled in the art will further appreciate that some vibrating densitometers use components of driver 114 and pickoffs 116, 118 to drive and sense the vibration of a vibrating member immersed in a fluid.
[0006] As mentioned above, the driver 114 and pickoffs 116, 118 typically comprise a coil and magnet assembly. The coil portion typically comprises a bobbin spindle with a coil wire wound around it and is used as an electromagnet to drive or sense the vibration of one or more conduits / vibration members. The ends of the coil wire must be coupled to input / output wires that connect the coil portion of the driver / pickoff to the control electronics. In conventional vibrometers, the respective ends of the coil wire and input / output wires are soldered or crimped to terminals located on the bobbin spindle.
[0007] For example, FIG. 2 illustrates a conventional coil section 200. The coil section 200 includes a substantially cylindrical body with a bobbin spindle 202 on which the coil wire can be wound. The conventional coil section 200 further includes terminals 204 and 206. The coil and / or terminal wires are coupled to the terminals 204 and 206 using crimps 208 and 210. In some embodiments, a vibrometer with one driver and two pickoffs may require six to twelve wire bonds to the electromagnet terminals of the coil section 200. However, soldering the wires to the terminals requires additional labor during assembly and can become more difficult as the wires become smaller in smaller meters / components. Additionally, there is increasing pressure to remove lead solder from flowmeter assemblies. Furthermore, the crimps 208 and 210 pinch the wire, causing stress concentrations and increasing the likelihood of the wire breaking and failing. For at least these reasons, achieving good contact between the wire and the terminals, either by soldering or crimping, can be difficult. Furthermore, once the meter is in operation, it may be used in a corrosive or thermally dynamic environment, which may further exacerbate weaknesses in the wire connections.
[0008] What is needed is a method of coupling one or more wires to a terminal that is easy to assemble, is robust, and works well with smaller wires. Summary of the Invention

[0041] 3A-6 and the following description depict specific examples to teach those skilled in the art how to make and use the best mode of the present application. For the purpose of teaching inventive principles, some conventional aspects have been simplified or omitted. Those skilled in the art will recognize variations from these examples that fall within the scope of the present application. Those skilled in the art will understand that the features described below can be combined in various ways to form multiple variations of the present application. Consequently, the present application is not limited to the specific examples described below, but only by the claims and their equivalents.
[0042] 3A-3F illustrate a terminal connector 300, or a portion thereof, according to one embodiment of the present application. FIG. 3A illustrates an exploded view of the disassembled terminal connector 300, and FIG. 3B illustrates a perspective view of the assembled terminal connector 300. FIG. 3C illustrates a cross-sectional view of the terminal connector 300 taken along section A-A' shown in FIG. 3B. FIG. 3D illustrates a detailed cross-section of FIG. 3C. FIGS. 3E and 3F illustrate a component 302, with FIG. 3E illustrating the component 302 wrapped with a first terminal wire 332 and FIG. 3F illustrating the component 302 wrapped with a first terminal wire 332 and at least a first electronic wire 334a.
[0043] Terminal connector 300 can comprise any electronic device that can be coupled to one or more input / output wires. In further embodiments, terminal connector 300 can be connected to an electronic device or computer that controls and / or monitors the electronic device. In further embodiments, terminal connector 300 can couple portions of one or more electronic devices together.
[0044] Terminal connector 300 includes a component 302. Component 302 may include an electronic device or element. In some embodiments, component 302 may further include, for example, a bobbin spindle 314. In some embodiments, bobbin spindle 314 may include an annular recess in a substantially cylindrical body of component 302 or a flanged or flangeless spindle member. However, in further embodiments, bobbin spindle 314 may have any form or shape known to those skilled in the art.
[0045] Component 302 further includes a component surface 322, best seen in FIG. 3A. In an embodiment of terminal connector 300, component surface 322 includes, but is not intended to be limited to, a substantially flat, circular surface on one end of a substantially cylindrically shaped component body. In some embodiments, component surface 322 can include any shape capable of coupling to cap member 304.
[0046] In the exemplary embodiment of component 302, component surface 322 includes four notches for wire passages 323. Wire passages 323 may allow wires to pass through component surface 322. In some embodiments, wire passages 323 may allow wires coupled to one or more terminal posts to pass through the body of component 302 and be wound, for example, around bobbin spindle 314. In some embodiments, wire passages 323 allow input / external wires to pass through the body of component 302. While four elongated wire passages 323 are depicted on component surface 322 in FIGS. 3A-3F , one skilled in the art will appreciate that this is not intended to be limiting. In some embodiments, terminal connector 300 may have zero or any number of wire passages 323, each having any shape.
[0047] Component 302 further includes a first terminal post 306 oriented substantially perpendicular to component surface 322. By substantially perpendicular, it is meant that the axis of first terminal post 306 is oriented within 0, 5, 10, 15, or 20 degrees of a normal to component surface 322. First terminal post 306 may include any cylinder, tab, or extension that can be used to secure or electrically couple any wires associated with terminal connector 300.
[0048] In some embodiments, component 302 may be fabricated from a metal such as copper or aluminum. However, in further examples, it may be fabricated from plastic or any other material known to those skilled in the art. In some embodiments, first terminal post 306 may be fabricated from metal or plastic, with other portions of component 302 being fabricated from the same or different materials. In embodiments in which first terminal post 306 comprises metal, this may help to facilitate an electrical connection between wires coupled between component 302 and cap member 304. In embodiments in which first terminal post 306 comprises plastic, this may help to facilitate a heat stake bond between component 302 and cap member 304, as will be further described below. In further embodiments, first terminal post 306 may comprise a combination of metal and plastic, as will be understood by those skilled in the art.
[0049] Terminal connector 300 further includes cap member 304. Cap member 304 may include any cover operable to couple to post 306 and apply pressure to wires wrapped around the terminal posts of component 302. Cap member 304 includes cap member surface 324 (the back side of cap member 304 in FIG. 3A ; see also FIG. 3C ). In embodiments of terminal connector 300, cap member surface 324 includes a substantially flat, circular surface on the component-facing end of a substantially cylindrically shaped cap member body. However, this is not intended to be limiting. In some embodiments, cap member surface 324 may include any shape capable of coupling to component 302.
[0050] In some embodiments, cap member surface 324 and component surface 322 can be configured to contact when terminal connector 300 is fully assembled. In some embodiments, cap member surface 324 and component surface 322 can be configured to be in close proximity but not actually touch when terminal connector 300 is fully assembled. In such examples, cap member surface 324 and component surface 322 can be configured to provide minimal space between component 302 and cap member 304 when terminal connector 300 is assembled.
[0051] The cap member 304 further comprises a first borehole 310 oriented substantially perpendicular from the cap member surface 324. By substantially perpendicular, it is meant that the axis of the first borehole 310 is oriented within 0°, 5°, 10°, 15°, or 20° of the normal to the cap member surface 324. The first borehole 310 passes through the cap member surface 324. In some embodiments, the first borehole 310 may or may not penetrate completely through the opposing end surface 326 of the cap member 304.
[0052] 3D , first borehole 310 can be seen to include a chamfer volume 328 between first borehole 310, first terminal post 306, and component surface 322. Chamfer volume 328 comprises an annular portion of material removed between a corner of first borehole 310 and component surface 322. Chamfer volume 328 can comprise a control volume of any shape configured to contain or compress together multiple windings 330 of one or more wires wound around first terminal post 306 between component surface 322, first borehole 310, and first terminal post 306 when first terminal post 306 is inserted into first borehole 310. In some embodiments, chamfer volume 328 can apply sufficient pressure to provide secure contact between one or more wire windings contained within chamfer volume 328 or between one or more wire windings and component 302. In some embodiments, the first chamfer volume 328 can be configured to prevent damage to one or more windings of the wire.
[0053] In some embodiments, the chamfer volume 328 has a conical annular shape, best seen in FIG. 3D . The conical annular shape has a triangular cross-section on each side of the terminal post 306. One skilled in the art will recognize that the conical annular shape can provide sufficient volume to compress but not deform two different gauge wires wound together when the cap member 304 is installed. The conical annular shape can further enable the advantage of easier removal of the cap member 304 from a mold during a plastic injection molding process when manufacturing the cap member 304.
[0054] The conical annular shape shown in Figure 3D is not intended to be limiting, and one skilled in the art will readily appreciate that the chamfer volume 328 can be configured to include any cross-sectional shape suitable for accommodating a desired wire gauge with a desired number of wire turns.
[0055] In some embodiments, the portion of the terminal post 306 that forms the outer edge of the chamfered volume 328 may be fabricated from metal to facilitate connections between the wires bonded thereto.
[0056] 3D , it can be seen that terminal connector 300 can further include a plurality of windings 330. In some embodiments, plurality of windings 330 can include a first terminal wire 332 having one or more first terminal wire windings around first terminal post 306. In some embodiments, first terminal wire 332 can connect an electronic component of component 302 to an external electronic component.
[0057] In some embodiments, the plurality of windings 330 may further include a first electronic wire 334a having one or more first electronic wire windings around the first terminal post 306. In some embodiments, the first electronic wire 334a may include a coil wire or any other wire associated with the component 302.
[0058] In some embodiments, the first terminal wire 332 may have a first gauge that is lower than the second gauge of the first electronic wire 334a. This may occur, for example, when a higher gauge wire is used for the coil wire and a lower gauge wire is used for the input / output wire. In some embodiments, the coil wire may be 34-46 gauge and the input / output wire may be 32 gauge.
[0059] In some embodiments, a first electronic wire 334a having a higher gauge may be wound between the component 302 and a first terminal wire 332 having a lower gauge. The conical annular chamfer volume 328 provides an improved fit for this particular configuration, providing reliable electrical contact between the first electronic wire 334a and the first terminal wire 332 having different gauges, while providing different spatial volumes for each wire to avoid crimping and damage.
[0060] In some embodiments, component 302 may further include a second terminal post 308 oriented substantially perpendicular to component surface 322. Second terminal post 308 may be used to couple a second terminal wire 335 to component 302, as shown in FIG.
[0061] In some embodiments, each of the first and second terminal posts 306, 308 may be paired with a separate cap member 304. However, in further embodiments, the cap member 304 may include a second borehole 312 oriented to be substantially perpendicular from the cap member surface 324 and positioned to couple around the second terminal post 308 when the first terminal post 306 is inserted into the first borehole 310. In some embodiments, the second terminal post 308 may have similar features to the first terminal post 306, and the second borehole 312 may have similar features to the first borehole 310.
[0062] In some embodiments, the first borehole 310 and the first terminal post 306 may be configured to facilitate a heat stake fit when the first terminal post 306 is inserted into the first borehole 310 and heat is applied to the first terminal post 306. In such embodiments, the cap member 304 may be fabricated from plastic.
[0063] The heat staking fit may include applying heat to the first terminal post 306 of the component 302 until the terminal post 306 is at least partially melted around the first bore hole 310. In embodiments in which the component 302 further includes a second terminal post 308, heat may also be applied to the second terminal post 308. In some embodiments, the heat staking fit may further include applying pressure between the component 302 and the cap member 304 to bring the members closer together during the melting operation. The pressure and applied heat allow the melted regions of the terminal posts 306, 308 to reform around the one or more bore holes 310, 312. In this manner, the heat staking fit may firmly join the component 302 to the cap member 304.
[0064] In some embodiments, first terminal post 306 and first borehole 310 may be substantially cylindrical in shape. In other embodiments, first terminal post 306 and first borehole 310 may comprise loosely conical shaped members designed to fit snugly together when fully inserted. However, in further embodiments, first terminal post 306 and first borehole 310 may comprise any elongated shape configured to fit snugly together when pressure is applied between component member 302 and cap member 304.
[0065] In further embodiments, first borehole 310 and terminal post 306 may be coupled to one another by pressure or a press fit. In further embodiments, fasteners or adhesives may be used to couple component 302 to cap member 304. In some embodiments, silicone adhesive may be used. In some embodiments, any combination of heat staking, adhesive, and fasteners may be used to couple component 302 to cap member 304. In further embodiments, component 302 and cap member 304 may be coupled to one another using any method known to one of ordinary skill in the art.
[0066] 4 illustrates a method 400 for assembling the terminal connection 300 according to one embodiment. The method 400 includes a step 412 in which the first terminal post 306 is inserted into the first borehole 310, as described above.
[0067] In some embodiments, method 400 may include additional steps. For example, method 400 may include any combination of steps 402-411 or 414.
[0068] In some embodiments, the method 400 may further include step 402. In step 402, the first electronic wire 334a may be wrapped around the first terminal post 306. For example, FIG. 3E shows the first electronic wire 334a wrapped around the first terminal post 306.
[0069] In some embodiments, the method 400 can further include step 404. In step 404, the first electronic wire 334a can be wrapped around the bobbin spindle 314. This can enable the component 302 to be used as an electromagnet, as described above. Figure 3E also shows the first electronic wire 334a wrapped around the first terminal post 306.
[0070] In some embodiments, the method 400 can further include step 406. In step 406, the first electronic wire 334a can be wrapped around the second terminal post 308. For example, FIG. 3E also shows the second electronic wire 334b wrapped around the second terminal post 308.
[0071] In some embodiments of step 406, a second electronic wire 334b may be wrapped around the second terminal post 308 instead of the first electronic wire 334a as described above.
[0072] In some embodiments, method 400 may further include step 408. In step 408, first terminal wire 332 may be wrapped around first terminal post 306 to create one or more first terminal wire windings, as described above. For example, FIG. 3E shows first terminal wire 332 wrapped once around first terminal post 306.
[0073] In some embodiments, method 400 can further include step 410. In step 410, a second terminal wire 335 can be wrapped around second terminal post 308, as shown in FIG. 3F. This configuration can be used to create an electromagnet that connects to two input / output wires, as described above.
[0074] In some embodiments, the first electronic wire 334a and the second electronic wire 334b can comprise opposite ends of the same electronic wire.
