Abstract
Description
Technical Field
[0001] This utility model relates to the field of tilt switch technology, specifically to a ball-type unidirectional multi-contact tilt switch. Background Technology
[0002] Most tilt switches currently on the market rely on the displacement of a single ball or contact to trigger, lacking a precise structure to limit the range of ball movement. This makes them prone to false triggering due to slight shaking, or functional failure due to unclear trigger direction definition. Since most tilt switches on the market use a single-point contact design, poor contact can easily occur if the contact is worn, oxidized, or the ball is misaligned. This is especially true in low-current scenarios, where the probability of conduction interruption is high, affecting the continuous operation of the device. In addition, some products add extra components such as springs and damping parts to achieve unidirectional function, resulting in complicated assembly steps and larger size. This not only increases manufacturing costs but also reduces the consistency of mass production. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a ball-type unidirectional multi-contact tilt switch.
[0004] The purpose of this utility model is achieved through the following technical solution: a ball-type unidirectional multi-contact tilt switch, including a base; the base is provided with a lower conductive element and an upper conductive element; the upper conductive element is located on top of the lower conductive element; The base has a stop wall at one end along its length; a limiting wall at the other end along its length; a plurality of stop protrusions are provided on the base along its length between the stop wall and the limiting wall; the stop protrusions pass through the lower conductive component.

[0008] The present invention is further configured such that the lower conductive member is provided with a plurality of clearance holes along its length; the abutment protrusion passes through the clearance holes.

[0014] The beneficial effects of this utility model are as follows: This utility model divides the active range of the conductive beads into a conductive area and an open circuit area by using the base's blocking wall, limiting wall and multiple sets of blocking protrusions. The conductive beads can only be triggered when they tilt towards the marked bending part, thus avoiding false triggering. In addition, the multi-point contact design with multiple conductive beads and multiple contact holes ensures that even if a single conductive bead is slightly offset, the other conductive beads can still maintain contact.

[0016] The present invention will be further described in conjunction with the following embodiments.
[0017] Depend on Figures 1 to 4As can be seen, the ball-type unidirectional multi-contact tilt switch described in this embodiment includes a base 1; the base 1 is provided with a lower conductive element 2 and an upper conductive element 3; the upper conductive element 3 is disposed on top of the lower conductive element 2; The base 1 has a blocking wall 11 at one end along the length direction; the base 1 has a limiting wall 12 at the other end along the length direction; the base 1 has a plurality of blocking protrusions 13 along the length direction between the blocking wall 11 and the limiting wall 12; the blocking protrusions 13 pass through the lower conductive member 2. Conductive beads 4 are movably provided between the blocking wall 11 and the blocking boss 13, between the limiting wall 12 and the blocking boss 13, and between two adjacent blocking bosses 13; the bottom of the conductive beads 4 abuts against the lower conductive component 2. The upper conductive element 3 is provided with multiple contact holes 31; the top of the conductive bead 4 is movably disposed in the contact hole 31.
[0018] Specifically, in this embodiment, the ball-type unidirectional multi-contact tilt switch has a stop wall 11, a limiting wall 12, and a stop boss 13 forming the directional movement range of the conductive ball 4, limiting the displacement of the conductive ball 4 to two trajectories: open circuit and conduction. The bottom of the conductive ball 4 always abuts against the lower conductive member 2, and the top moves within the contact hole 31. The circuit is switched on and off by the contact and separation between the conductive ball 4 and the wall of the contact hole 31. The core is to use the displacement of the conductive ball 4 driven by gravity or external force to complete the switching of the conductive path.
[0019] When the conductive bead 4 tilts towards the marked bend 61, due to the blocking effect of the blocking wall 11 and the blocking boss 13, the top of the conductive bead 4 cannot abut against one end of the contact hole 31 wall, thus preventing the upper conductive member 3 and the lower conductive member 2 from being energized; when the conductive bead 4 tilts towards the connecting bend 71, the top of the conductive bead 4 abuts against the other end of the contact hole 31 wall, thus making the upper conductive member 3 and the lower conductive member 2 conductive.
[0020] This embodiment describes a ball-type unidirectional multi-contact tilt switch, in which the base 1 and the lower conductive component 2 are integrally formed by embedded injection molding. The embedded injection molding process pre-places the lower conductive component 2 in an injection mold, injects plastic material to form the base 1, making the lower conductive component 2 and the base 1 an inseparable whole. No additional connecting structure is required, effectively eliminating assembly gaps between the lower conductive component 2 and the base 1, preventing the conductive component from detaching during long-term use; reducing assembly steps, improving mass production efficiency, and simultaneously enhancing the protective properties of the base 1 for the lower conductive component 2, reducing the impact of external vibrations on the position of the lower conductive component 2.
[0021] This embodiment describes a ball-type unidirectional multi-contact tilt switch. The lower conductive element 2 has a lower pin 21, which protrudes from the base 1. The upper conductive element 3 has an upper pin 32. The lower pin 21 and the upper pin 32 serve as connection terminals for the lower conductive element 2 and the upper conductive element 3 to external circuits, respectively. The protrusion from the base 1 facilitates insertion into a circuit board or wiring, enabling electrical connection between the switch and the circuit.
[0022] This embodiment describes a ball-type unidirectional multi-contact tilt switch, in which the lower pin 21 is located at one end of the base 1 along its length, and the upper pin 32 is located at the other end of the base 1 along its length. Specifically, the upper pin 32 and the lower pin 21 are located at opposite ends of the base 1, and this staggered arrangement avoids interference between the pins during wiring. Simultaneously, it ensures that the current path is distributed along the length of the base 1, consistent with the direction of movement of the conductive ball 4, reducing circuit signal interference and improving current stability during conduction.
[0023] This embodiment describes a ball-type unidirectional multi-contact tilt switch. The lower conductive element 2 has multiple clearance holes 22 extending along its length; the blocking boss 13 passes through the clearance holes 22. Specifically, the clearance holes 22 provide space for the blocking boss 13 to extend from the lower conductive element 2 into the interior of the base 1, thus blocking the conductive ball 4. Simultaneously, the cooperation between the blocking boss 13 and the clearance holes 22 positions the lower conductive element 2 within the base 1. Furthermore, it ensures that the blocking boss 13 accurately separates the active chambers of the conductive ball 4, improving the accuracy of unidirectional triggering.
[0024] This embodiment describes a ball-bearing type unidirectional multi-contact tilt switch, which further includes a copper tube 5. The base 1, lower conductive element 2, and upper conductive element 3 are all sleeved inside the copper tube 5. The copper tube 5, as an external covering structure, can prevent dust, moisture, and other impurities from entering the switch, while also providing physical support for the base 1, lower conductive element 2, and upper conductive element 3, thus enhancing the overall structural strength.
[0025] This embodiment describes a ball-type unidirectional multi-contact tilt switch, wherein the base 1 has limiting inclined surfaces 14 on both sides of the conductive ball 4. This design prevents the conductive ball 4 from getting stuck in the corner of the base 1 chamber or deviating from its preset path.
[0026] This embodiment describes a ball-type unidirectional multi-contact tilt switch, wherein the contact hole 31 is racetrack-shaped. Specifically, this design improves conduction stability; the rounded end design avoids wear caused by collision between the conductive ball 4 and the corner of the contact hole 31, extending the service life of the conductive ball 4 and the contact hole 31.
[0027] This embodiment describes a ball-type unidirectional multi-contact tilt switch. The upper conductive element 3 has a marked bending portion 61 at one end along its length. The base 1 has a first locking groove 62 that engages with the marked bending portion 61. The engagement between the marked bending portion 61 and the first locking groove 62 allows for detachable fixing of the upper conductive element 3 to the base 1 without the need for glue or welding. Simultaneously, the snap-fit structure restricts the vertical and horizontal displacement of the upper conductive element 3.
[0028] This embodiment describes a ball-type unidirectional multi-contact tilt switch. The upper conductive element 3 has a connecting bend 71 at one end along its length. The upper conductive element 3 is connected to the upper pin 32 via the connecting bend 71. The base 1 has a second slot 72 that engages with the connecting bend 71. The engagement between the connecting bend 71 and the second slot 72 allows for detachable fixing of the upper conductive element 3 to the base 1 without the need for glue or welding. Simultaneously, the snap-fit structure restricts the vertical and horizontal displacement of the upper conductive element 3.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
