Description

  The present disclosure relates generally to proximity switches, and more specifically to a housing for a small magnetic trigger proximity switch.

  Magnetic proximity switches, also known as limit switches, are commonly used for position sensing. Typically, a magnetically triggered proximity switch includes a sensor that is adapted to detect the presence of a target without physically touching the target. Typically, the sensor may include a switching circuit mechanism encapsulated within the switch body, which typically includes a plurality of levers and contacts that are biased to a first position by one or more springs. including. When a target, typically including a permanent magnet contained within the housing, passes within a predetermined range of the sensor, the magnetic flux generated by the target magnet triggers the switching circuitry, thereby closing the normally open circuit. A normally open circuit closure is detected by the processor and a signal is sent to an operator or automated operating system to indicate the presence of a target within a predetermined range of the sensor. The target is typically secured to a displaceable element of the system, such as a valve stem, and the sensor is typically secured to a stationary element of the system, such as a valve body. When so configured, the sensor can detect when a displaceable element changes position.

  Typically, the sensor is disposed in or secured to a durable housing to protect the sensor. The connector socket assembly is coupled to the housing of the sensor (eg, by a welding operation), and the connector socket assembly includes a field side connector. However, due to the relatively large physical size of the sensor required to encapsulate the switching circuitry, the typical sensor housing is relatively large and the sensor placement within an area having limited free space. Can not be used for applications that require. In addition, the need to supply power to the sensor limits the applications in which the sensor can be used.

  While a relatively small magnetic trigger proximity switch (and correspondingly smaller housing) may be desirable, the ability to reduce the size of the proximity switch can be limited by several factors. Specifically, in addition to a programmable logic controller ("PLC") level load of about 5V, if a relatively high load value is required, a larger contact is accordingly required to accommodate a larger load. Yes, these large contacts limit the ability of the switch to be reduced in size. In addition, as described above, there are numerous components disposed within the switch housing, and the relatively complex actuation assembly size limits the minimum size of the switch. Such complex actuation assemblies also increase the proximity switch manufacturing time and cost.

  In accordance with an exemplary aspect of the present invention, a quickly removable connector assembly includes a housing that extends from a first end along a longitudinal axis to a second end that is longitudinally opposite. The housing includes one or more inner surfaces that cooperate to define a hole extending from the second end to a point adjacent to the first end, the hole being a first end of the housing. The hole includes a first hole so as not to extend through the part.

  As illustrated in FIG. 1, the quickly removable connector assembly 10 includes a housing 12 that extends from a first end 16 along a longitudinal axis 14 to a second end 18 that is longitudinally opposite. Including. The housing 12 includes one or more inner surfaces 20 that cooperate to define a hole 22 that extends from the second end 18 to a point adjacent to the first end 16, the hole 22 being a housing. Twelve first ends 16 are prevented from extending through, and the holes 22 include first holes 24. The quickly removable connector assembly 10 also includes a proximity switch 26 disposed in the first hole 24. The proximity switch 26 includes a switch body 28 that extends along a body longitudinal axis 30, the switch body 28 having a first end disposed adjacent to the first end 16 of the housing 12. 32 and a second end 34 opposite to the longitudinal direction. The proximity switch 26 also includes a first contact member 36 and a second contact member 38, each of the first and second contact members 36, 38 extending longitudinally with the first ends 42a, 42b. And opposite second ends 44a, 44b. The second ends 44 a and 44 b are disposed in the switch body 28, and the first ends 42 a and 42 b are disposed outside the switch body 28. A portion of each of the first and second contact members 36, 38 extends from the second end 34 of the switch body toward the second end 18 of the housing 12. In the first switch position (illustrated in FIG. 8A), the contacts of the displaceable switching assembly 47 (such as the common contact 45) contact a portion of the first contact member 36 and the second switch position (in FIG. 8B). In the illustration), the contacts of the switching assembly 47 contact a portion of the second contact member 38.

And an external connection assembly 46 including a pin 48b. The first pin 48 a and the second pin 48 b each extend in the longitudinal direction, and at least a part of each of the first pin 48 a and the second pin 48 b extends and is disposed in the hole 22. . When so configured, the quickly removable connector assembly 10 provides a sealed, easily attachable component that eliminates the need for a separate housing for the proximity switch 26. In addition, the magnetic trigger proximity switch 26 is permanently disposed within (i.e., integral with) the housing 12, and the proximity switch 26 uses a relatively small number of moving parts to provide a small proximity switch 26, As a result, the connector assembly 10 can be quickly removed. Furthermore, no external power supply is required because the proximity switch uses magnetic force to switch from the first switch position to the second switch position (and vice versa).

  Referring to the connector assembly 10 that can be quickly removed in more detail, the housing 12 is longitudinally from a first end 16 along its longitudinal axis 14 to its first end, as illustrated in FIG. 1Aa.

The bottom hole surface 66 and the end surface 60 can be displaced longitudinally at any suitable distance. For example, the longitudinal distance between the bottom hole surface 66 and the end surface 60 may be 3% to 10% of the entire length of the housing 12 in the longitudinal direction. The bottom hole surface 66 may have any suitable shape or combination of shapes. For example, the bottom hole surface 66 may be perpendicular or substantially perpendicular to the longitudinal axis 14 and the bottom hole surface 66 may be planar or substantially planar. Alternatively, the bottom hole surface 66 may be conical, frustoconical, circular, partially tapered, and / or partially circular.

The second hole 62 is defined by a second longitudinal inner wall 70 that can extend upward from a point adjacent to the upper end 72 of the first inner wall 68 to a point adjacent to the midpoint 50 of the housing 12. Can be done. The second inner wall 70 can have any suitable shape or combination of shapes, such as a cylindrical shape. The diameter of the second inner wall 70 (ie, the diameter of the circular cross-sectional shape of the second inner wall 70) is larger than the diameter of the first inner wall 58 (ie, the diameter of the circular cross-sectional shape of the first inner wall 58). A shoulder 74 may be formed that extends radially from the upper end 72 of the first inner wall 68 to the lower end 76 of the second inner wall 70. Alternatively, the diameter of the second inner wall 70 may be equal to or smaller than the diameter of the first inner wall 58. Instead of a circular cross-sectional shape, the second inner wall 70 may have, for example, an elliptical, polygonal, and / or partial polygonal cross-sectional shape.

  Referring once again to FIGS. 1A and 2, the hole 22 may include a third hole 64, which may include the second hole 62 and the second end 18 of the housing 12. Between the two.

The third inner wall 78 may have any suitable shape or combination of shapes, such as a cylindrical shape. The diameter of the third inner wall 78 (that is, the diameter of the circular sectional shape of the third inner wall 78) is larger than the diameter of the second inner wall 70 (that is, the diameter of the circular sectional shape of the second inner wall 70). The shoulder 82 that extends radially from the upper end 80 of the second inner wall 68 to the lower end 84 of the third inner wall 78 can thereby be formed. Alternatively, the diameter of the third inner wall 78 may be equal to or smaller than the diameter of the second inner wall 70. Instead of a circular cross-sectional shape, the third inner wall 78 may have, for example, an elliptical, polygonal, and / or partial polygonal cross-sectional shape.

  A portion of the second outer surface 92 of the second outer portion 54 or a portion of the third inner wall 78 is connected to the second end 18 of the housing 12 with a standard female plug 280 (illustrated in FIGS. 9A and 9B). It may include one or more features that allow it to be mated or removably coupled thereto. For example, a portion of the second outer surface 92 of the second outer portion 54 may be threaded. In addition, one or more slots (not shown) can extend through the second outer surface 92 to the third inner wall 78, and the one or more slots can extend from the plug 280 and the housing 12. It may be adapted to provide a bayonet connection with the second end 18. In addition, a longitudinal plane 93 (illustrated in FIG. 1B) can be disposed in the third bore 64, and the plane 93 is adapted to prevent relative rotation between the plug 280 and the housing 12. Can be done.

  Referring to FIG. 2, the housing 12 also has an end that extends radially from the upper end 88 of the third inner wall 78 to the upper end 90 of the second outer surface 92 of the second outer portion 54 of the housing 12. A wall 86 may be included. The end wall 86 may have any suitable shape or combination of shapes. For example, end wall 86 may be perpendicular or substantially perpendicular to longitudinal axis 14 and end wall 86 may be planar or substantially planar. Alternatively, end wall 86 may be conical, frustoconical, circular, partially tapered, and / or partially circular. The housing 12 may be made of a nonmagnetic material such as aluminum or plastic.

However, the switch body 28 may have an arbitrary cross-sectional shape such as a polygon or an ellipse. The switch body 28 can include a first body half 28a and a second body half 28b. Since the second body half 28b may be identical to the first body half 28a, only the first body half 28a is illustrated. Each of the first body half 28a and the second body half 28b may be formed from plastic, for example, using a conventional process such as injection molding. The plastic may be a high temperature material that allows the switch body 28 to be exposed to an environment that can damage conventional plastic materials.

The first body half 28a also includes an open first end 32 that includes a semi-cylindrical second magnet cavity 154, the second magnet cavity 154 extending along the plane of the mating surface 151. Can extend inwardly along the body longitudinal axis 30. The second magnet cavity 154 is sized to receive a detector magnet assembly 158 illustrated in FIG. 4 that includes a disk-shaped second magnet 146 and a magnet base 160 coupled to the second magnet 146. As a result, the detector magnet assembly 158 can be slidably displaced within the second magnet cavity 154 along the body longitudinal axis 30.

  The semi-cylindrical first magnet cavity 162 is also within the body 28 such that the longitudinal axis of the disc-shaped first magnet 114 is substantially aligned with the body longitudinal axis 30 of the first body half 28a. The first body half 28a may be formed to receive and secure the fixed first magnet 114.

Alternatively, the magnet base 160 may be made from a non-magnetic material, and the second magnet 146 may be secured to the magnet base 160 mechanically or adhesively.

  Still referring to FIGS. 3A and 4, the proximity switch 26 further includes a first magnet 114, also referred to as a bias magnet. The first magnet 114 may have a cylindrical shape or a disk shape. The first magnet 114 may also have an aperture 190 formed along the central longitudinal axis of the first magnet 114, and the aperture 190 may be sized to receive the actuator arm 166. .

It can be received in the first magnet cavity 162 of the body 28. The first magnet 114 may be made from the same material as the second magnet 146, but the radius and thickness of the first magnet 114 may each be smaller than the respective radius and thickness of the second magnet 146. . The first magnet 114 may be positioned within the first magnet cavity 162 such that the second magnet 146 is attracted to the first magnet 114. That is, when the north pole of the second magnet 146 faces the second end 34 of the switch body 28, the south pole of the first magnet 114 faces the north pole of the second magnet 146. Is done. Conversely, when the S pole of the second magnet 146 faces the second end 34 of the switch body 28, the N pole of the first magnet 114 faces the S pole of the second magnet 146. Established.

In the first switch position shown in FIG. 8A, the common contact 45 of the cross arm 138 contacts the primary contact 128 of the primary arm 36, thereby completing the circuit between the common member 116 and the primary arm 36. In the second switch position shown in FIG. 8B, the common contact 45 of the cross arm 138 contacts the secondary contact 136 of the secondary arm 38, thereby providing a circuit between the common member 116 and the secondary arm 38. Complete.

  Still referring to FIGS. 3A, 4, 7B, the proximity switch 26 also includes an actuator arm 166 that is part of the displaceable switching assembly 47. Actuator arm 166 may be an elongated cylinder having a first end 117 and a second end 218 opposite the first end 117. Instead of a cylinder, the actuator arm 166 may have any suitable cross-sectional shape or combination of shapes, such as a square, elliptical, or polygonal shape. The actuator arm 166 may be made from a plastic material or any other suitable material. Actuator arm 166 may be slidably disposed in upper arm cavity 164 and lower arm cavity 170 of switch body 28, each of upper arm cavity 164 and lower arm cavity 170 being slightly smaller than the outer diameter of actuator arm 166. Can have a large inner diameter. The actuator arm 166 can also extend through an aperture 190 in the first magnet 114 when the first magnet 114 is disposed in the first magnet cavity 162. The first end 117 of the actuator arm 166 can include a groove 220 that provides an opening in the cross arm 138 to secure the actuator arm 166 to the cross arm 138 as shown in FIG. 7B. A defining edge 222 may be received. However, the first end 117 may be coupled to the cross arm 138 by any means known in the art, such as, for example, mechanical fastening. The second end 218 of the actuator arm 166 may be coupled to the magnet base 160 of the detector magnet assembly 158 in a manner similar to coupling the first end 117 into the cross arm 138.

  In operation, the first magnet 114 provides a magnetic force that attracts the second magnet 146. This attractive force displaces the detector magnet assembly 158 toward the first magnet 114, thereby displacing the actuator arm 166 toward the second end 34 of the switch body 28. The displacement of the actuator arm 166 rotates the cross arm 138 about the second end 44c of the common member 116 so that the common contact 45 contacts the primary contact 128. In this first switch position shown in FIG. 8A, a circuit is completed between the primary arm 36 and the common member 116 (ie, the primary arm 36 is electrically coupled to the common member 116). Thus, the closed circuit resulting from the first switch position is the first end 42c of the common member 116 (via the third pin 48c of the external connection assembly 46) and the first end 42a of the primary arm 36. May be detected by a processor operatively connected to (via the first pin 48a of the external connection assembly 46).

The greater force causes the detector magnet assembly 158 to move toward the target 224 and away from the first magnet 114, thereby causing the actuator arm 166 to be rigidly coupled to the magnet base 160 of the detector magnet assembly 158. Displace. When the actuator arm 166 is displaced, the cross arm 138 disengages the common contact 45 from the contact with the primary contact 128 and moves the second end 44c of the common member 116 to contact the secondary contact 136. Is rotated around the center. In this second switch position shown in FIG. 8B, a circuit is completed between the secondary arm 38 and the common member 116 (ie, the secondary arm 38 is electrically coupled to the common member 116). .

  Thus, the closed circuit resulting from the second switch position is the first end 42c of the common member 116 (via the third pin 48c of the external connection assembly 46) and the first end of the secondary arm 38. 42b (via the second pin 48b of the external connection assembly 46) can be detected by the processor. When the target 224 is no longer within the predetermined range of the proximity switch 26 disposed in the housing 12, the magnetic force between the first magnet 114 and the second magnet 146 is the second magnet 146 and the target. The proximity switch 26 moves to the first position in the manner described above.

  Those skilled in the art will recognize that the magnetic force between the target 224 and the second magnet 146 is the relative magnitude of the target 224 and the second magnet 146, and the distance between the target 224 and the second magnet 146, etc. It will be appreciated that a number of factors may depend and these variables may be adjusted to provide optimal interaction between proximity switch 26 and target 224.

As a result, the magnetic force between the target 224 and the second magnet 146 is larger than the magnetic force between the second magnet 146 and the first magnet 114. The greater force displaces the cross arm 138 of the switching assembly 47 to the second switch position (shown in FIG. 8B). The closed circuit resulting from the second switch position includes the first end 42c of the common member 116 (via the third pin 48c of the external connection assembly 46) and the first end 42b of the secondary arm 38 ( May be detected by a processor 282 operatively connected to (via second pin 48b of external connection assembly 46).

  As previously described, the quickly removable connector assembly 10 reduces the number of components used in conventional sensor assemblies and allows the separate housing of the proximity switch 26 to be removed. In addition, the proximity switch 26 may also include a magnetically actuated displaceable switching assembly 47, such a mechanism that allows an overall reduction in the size of the proximity switch 12, and further the proximity switch 26 can be reduced in size.

  Changes may be made to the disclosed embodiments of proximity switch 26 that are still within the scope of the appended claims. For example, instead of the single pole / single throw configuration described, a double pole / double throw configuration is also contemplated. In addition, an LEDS may be included in the housing to visually indicate whether the proximity switch is in the first switch position or the second switch position.
