SWITCHING DEVICES

Abstract

The invention relates to a switching device, comprising a housing; at least one lead piece, each lead piece having a lead terminal; and a locking base, attached to the housing, allowing at least one partial surface of the lead terminal of one of at least one lead piece to be fitted with the locking base, so that the lead terminal is stably locked to the locking base together with the conductive connector by the support of the locking base. By arranging the locking base, after the lead terminal is locked and fitted to the housing, the housing generally bears most of the torsional and tensile forces of the wire during installation. As a result, the tensile strength of the lead terminal during locking is significantly enhanced, completely avoiding functional failure of the device due to breakage and detachment of the lead terminal and housing due to pulling by uncontrollable external forces; furthermore, the relay can achieve "mechanical-electromechanical" separation function during installation.

Description

Switches

[0001] This disclosure claims priority to Chinese patent application No. 202311351857.3 filed on October 18, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of switching electrical appliances, and in particular to a relay. Background Art

[0003] Relays, as electronic control devices, control high currents using low currents. They are widely used in automatic control circuits, providing functions such as automatic regulation, safety protection, and circuit switching. Relays typically have terminals for connecting to external circuits with high currents controlled by the relay.

[0004] Existing relays directly use lead terminals to lock with nuts, screws, welding pieces and wires. As shown in Figures 38-39, the two lead terminals 2 and 3 of the relay 1 are locked with the wires 4 and the connecting piece 5 respectively by nuts and screws. As a result, during the locking process, the torsional force generated on the lead terminals 2 and 3 will damage the base and glue used to fix the lead terminals 2 and 3, causing hidden dangers such as cracking and damage to the base structure and the sealing glue, causing the technical parameters of the relay to deteriorate, and the contact reliability of the overall conductive system to be reduced, resulting in problems such as overheating and functional failure of the relay and equipment. In addition, since the coil pins 7 of the relay 1 are already welded to the circuit board 6 and the connecting piece 5 is also fixed, if the wire 4 is pulled during the installation process, the lead terminal 2 will be subjected to uncontrollable external force. At this time, the force fulcrum is located at the weak point where the lead terminal 2 and the base meet, which can easily cause deformation of the lead terminal 2, or even cause the entire lead terminal 2 and the base structure that fixes the lead terminal 2 to be damaged and fall off together, causing the device to directly fail and become unusable.

[0005] Public content

[0006] To address the above problems, the present disclosure provides a switching device.

[0007] This disclosure is implemented using the following scheme:

[0008] The present disclosure provides a switching device, comprising a housing and at least one lead-out piece, wherein the lead-out piece has a lead-out end. The switching device also comprises a locking mounting platform, wherein the locking mounting platform is attached to the housing and enables at least one partial surface of at least one of the lead-out ends to be mounted against the locking mounting platform. The lead-out end can be stably locked on the locking mounting platform together with a conductor connector by means of the abutment support of the locking mounting platform.

[0009] In one embodiment, a first connecting structure is provided on the locking mounting platform, and the first connecting structure is non-twistably provided on the locking mounting platform, and the first connecting structure can be connected and cooperated with the second connecting piece, so as to lock the lead-out end and the conductor connecting piece together on the locking mounting platform.

[0010] In one embodiment, the first connection structure is a nut, and the nut is integrally arranged on the locking mounting platform, so that the nut is non-twistably arranged on the locking mounting platform.

[0011] In one embodiment, the first connection structure is a threaded connection portion formed on the locking mounting platform, so that the threaded connection portion as the first connection structure is non-twistably arranged on the locking mounting platform.

[0012] In one embodiment, the first connecting structure is a nut, the second connecting member is a screw, a locking hole is provided on the lead-out end, and the diameter of the locking hole is larger than the diameter of the screw.

[0013] In one embodiment, a locking and anti-twist structure that cooperates with each other is provided between the locking installation platform and the local surface of the lead-out end.

[0014] In one embodiment, the locking and anti-twist structure is a boss and a groove that cooperate with each other.

[0015] In one embodiment, a cylindrical protrusion is provided on the lead-out end, and a groove matching the protrusion on the lead-out end is provided on the locking mounting platform, thereby forming the locking and anti-twisting structure.

[0016] In one embodiment, a chamfer is provided between the housing and the locking mounting platform.

[0017] In one embodiment, the switching device is a relay.

[0018] The technical solution provided by this disclosure has the following technical effects:

[0019] 1. The present invention provides a locking installation platform so that after the lead-out terminal is locked with the shell, the shell as a whole bears most of the torsional force, and the shell as a whole bears the pulling force of the wire during installation. This not only greatly improves the tensile strength of the lead-out terminal when locked, but also completely avoids the problem of equipment malfunction caused by damage and falling of the static lead-out terminal and the shell due to uncontrollable external force when installing the wire. It can also realize the "electromechanical" separation function of the relay during installation, so that the lead-out terminal mainly bears the current, and the shell mainly bears the mechanical installation force, optimizes the force load of each component, and makes the structural parts mainly bear the force load, and the metal lead-out parts bear the current load, so as to maximize the function of each component.

[0020] 2. The present invention provides a locking and anti-twist structure, so that after the lead-out terminal is locked with the housing, the torsional force can be further borne by the housing as a whole, while the lead-out piece does not bear the torsional force, resulting in a smaller force on the lead-out piece, thus preventing the torsional force generated on the lead-out terminal from damaging the housing and glue used to fix the lead-out terminal, causing the housing structure and the sealing glue to crack or break, thereby significantly improving the structural strength and service life of the relay. It also further realizes the "electromechanical" separation function of the relay during installation, allowing the lead-out terminal to only bear the current and the housing to bear the mechanical installation force, thereby optimizing the load of each component, and making the structural component bear the main load, while the metal lead-out component bears the current load, maximizing the function of each component.

[0021] 3. The present invention provides locking holes on the first lead-out end and the second lead-out end respectively. The diameter of the locking holes is larger than the diameter of the screw, so that the locking holes give way to the screw, so that the lead-out end does not bear lateral tension after locking, and the force on the lead-out end is smaller.

[0061] To further illustrate various embodiments, the present disclosure is accompanied by accompanying drawings. These drawings form part of the disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of the present disclosure. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0062] The present disclosure will now be further described with reference to the accompanying drawings and specific embodiments.

[0063] Example 1

[0064] As shown in Figures 1-9, this embodiment provides a relay comprising a housing 30, a magnetic circuit system, and a contact system. The housing 30 may include a housing base 310 and an outer cover 330. The outer cover 330 is assembled and mated with the housing base 310, thereby forming an internal installation space within the housing base 310 and the outer cover 330. The magnetic circuit system and the contact system are mounted within the internal installation space. The magnetic circuit system is used to actuate the contact system, causing it to engage or disengage.

[0065] The contact system includes at least one lead-out tab extending from the housing 30 to form a lead-out terminal. The lead-out terminal is used to connect to a conductor connector, thereby connecting the relay to the external circuit it controls. The conductor connector may be, for example, a wire or a terminal block. A locking mounting platform 320 is attached to the housing 30. At least a portion of the surface of at least one of the lead-out tabs can be abutted against the locking mounting platform 320, thereby allowing the lead-out tab and the conductor connector to be stably locked to the locking mounting platform 320 through the abutment and support of the locking mounting platform 320.

[0066] The locking mounting platform 320 is provided with a first connecting structure, and the first connecting structure is non-rotatably arranged on the locking mounting platform 320. The first connecting structure is connected and matched with the second connecting member, thereby locking the lead-out terminal and the conductor connector together on the locking mounting platform 320.

[0067] As shown in Figures 1 and 4-9, in this embodiment, the relay's lead tabs include a first lead tab 10 and a second lead tab 20. The first lead tab 10 and the second lead tab 20 are respectively provided with a first lead end 11 and a second lead end 21, which are used to connect to the external circuit controlled by the relay. The first lead tab 10 and the second lead tab 20 are mounted against the locking mounting platform 320.

[0068] The first connecting structure can be, for example, a threaded connector, such as a screw or a nut, which is non-rotatably arranged on the locking mounting platform 320. The second connector is a connector that cooperates with the first connecting structure, such as a screw that cooperates with a nut. In some embodiments, a threaded connector retaining structure is provided on the locking mounting platform 320, so that the threaded connector as the first connecting structure is non-rotatably connected to the locking mounting platform 320. In this embodiment, a nut 302 is integrated on the locking mounting platform 320 as the first connecting structure, so that the nut 302 is non-rotatably arranged on the locking mounting platform 320. The nut 302 can cooperate with the screw to lock the first lead-out terminal 11 or the second lead-out terminal 21 with the wire and the locking mounting platform 320.

[0069] In some embodiments, the first connection structure can be, for example, a threaded connection portion formed directly on the locking mounting platform 320, such that the threaded connection portion serving as the first connection structure is non-twistably disposed on the locking mounting platform 320. For example, the threaded connection portion can be a threaded hole or a threaded boss formed on the locking mounting platform 320. The threaded connection portion can be coupled with the second connector to lock the lead-out terminal and the conductor connector together on the locking mounting platform 320.

[0070] In traditional relay structures, there's no locking mounting platform between the lead-out terminal and the housing. When the lead-out terminal is locked, the torque generated on the lead-out terminal can damage the housing and adhesive securing the lead-out terminal, leading to potential cracking and damage to the housing structure and the sealing adhesive. This can degrade the relay's technical parameters, reduce the overall contact reliability of the conductive system, and cause the relay and equipment to overheat and malfunction. Furthermore, when the terminal is installed, it pulls on the wires, subjecting the static lead-out terminal to uncontrollable external forces. The force fulcrum is located at the weak junction where the static lead-out terminal meets the housing, causing the entire static lead-out terminal and the housing structure that secures it to break and fall off, rendering the device inoperable and unusable.

[0071] This embodiment provides a locking installation platform so that after the lead-out terminal is locked with the housing 30, the housing 30 as a whole bears most of the torsional force, and the housing 30 as a whole bears the pulling force of the wire during installation. This not only greatly improves the tensile strength of the lead-out terminal when locked, but also completely avoids the problem of equipment malfunction caused by damage and falling of the static lead-out terminal and the housing due to uncontrollable external force during installation of the wire. It can also realize the "electromechanical" separation function of the relay during installation, so that the lead-out terminal mainly bears the current, and the housing 30 mainly bears the mechanical installation force, optimizes the force load of each component, and makes the structural parts mainly bear the force load, and the metal lead-out parts bear the current load, so as to maximize the function of each component.

[0072] As shown in FIG. 1-2 , in one embodiment, a chamfer is provided between the housing 30 and the locking mounting platform 320 to improve the force distribution of the housing 30 and reduce the occurrence of stress concentration.

[0073] As shown in Figures 1 and 4-9, in this embodiment, locking holes 112 and 212 are respectively provided on the first lead-out end 11 and the second lead-out end 21. In one embodiment, the diameter of the locking holes 112 and 212 is larger than the diameter of the screw, so that the locking holes 112 and 212 give way to the screw, so that the lead-out ends are not subjected to lateral tension after locking, and the force on the lead-out ends is smaller.

[0074] In one embodiment, the locking mounting platform 320 is provided with a locking anti-twist structure that cooperates with the lead-out terminal. The locking anti-twist structure can limit the relative position between the lead-out terminal and the locking mounting platform 320, and limit the relative torsion between the lead-out terminal and the housing 30. Specifically, in this embodiment, a locking anti-twist structure is provided between the first lead-out terminal 11 and the second lead-out terminal 21 and the housing 30. The locking anti-twist structure can limit the relative position between the first lead-out terminal 11 and the second lead-out terminal 21 and the housing 30, and limit the relative torsion between the first lead-out terminal 11 and the second lead-out terminal 21 and the housing 30.

[0075] This embodiment provides a locking and anti-twist structure, so that after the lead terminal is locked with the housing 30, the entire housing 30 can bear the torsional force, while the lead tab does not bear the torsional force, resulting in a smaller force on the lead tab. This prevents the torsional force generated on the lead terminal from damaging the housing and glue used to secure the lead terminal, causing cracking and damage to the housing structure and the sealing glue, significantly improving the structural strength and service life of the relay. It also further realizes the "mechanical and electrical" separation function of the relay during installation, allowing the lead terminal to only bear the current and the housing 30 to bear the mechanical installation force. This optimizes the load of each component, and makes the structural components bear the main load, while the metal lead parts bear the current load, maximizing the function of each component.

[0076] As shown in Figures 1-9, the locking and anti-twist structure provided between the lead terminals and the locking mounting platform 320 is a mating structure of protrusions and grooves. Specifically, in this embodiment, protrusions 111 and 211 are provided on the first and second lead terminals 11 and 21, and a groove 301 is provided on the locking mounting platform 320. The protrusions 111 and 211 cooperate with the groove 301 to achieve a locking and anti-twist connection between the first and second lead terminals 11 and 21 and the locking mounting platform 320.

[0077] In this embodiment, the example of providing a protrusion on the lead-out terminal and providing a groove on the locking mounting platform is used for explanation. However, as those skilled in the art can expect, providing a groove on the lead-out terminal and providing a protrusion on the locking mounting platform is also a feasible solution, which can also achieve a locking and anti-twisting connection between the lead-out terminal and the locking mounting platform.

[0078] In this embodiment, the protrusions 111 and 211 are cylindrical, and the number of protrusions 111 is at least 2, and the number of protrusions 211 is at least 2. The grooves 301 have a matching shape and number, so that a locking and anti-twisting connection is achieved between the lead-out end and the locking mounting platform.

[0079] In other embodiments, protrusions 111 and 211 may have other shapes, such as regular polygons or elongated strips. Recess 301 has a corresponding shape, ensuring a locked, twist-proof connection between the lead terminal and the locking mounting platform. However, cylindrical protrusions and recesses are more convenient to process and manufacture, so this embodiment uses a cylindrical protrusion as the specific implementation structure.

[0080] In other embodiments, the locking holes 112 and 212 not only give way to the screws, but also expand outward to form irregular shapes such as a "D" shape (as shown in the locking holes 112' and 212' in Figures 34-35). The locking protrusions 303 and 304 (as shown in Figure 36) provided on the locking mounting platform 320 not only give way to the screws, but also cooperate with the locking holes 112' and 212' in the locking holes 112' and 212'. In this way, the locking holes can achieve anti-twisting while giving way to the screws, so that the lead-out end is not subjected to lateral tension after locking.

[0081] In other embodiments, the locking and anti-twisting structure set between the lead-out end and the locking mounting platform 320 can also be a edging 113 formed by the downward extension of the edge of the lead-out end (as shown in Figure 37), and the edging 113 is abutted against the side of the locking mounting platform 320, thereby forming a locking and anti-twisting structure set between the lead-out end and the locking mounting platform 320.

[0082] As shown in Figures 1 and 4-9, in this embodiment, the first lead-out terminal 11 and the second lead-out terminal 21 are mounted and matched with the locking mounting platform 320, and the groove 301 is provided on the locking mounting platform 320. In this embodiment, the first lead-out tab 10 and the second lead-out tab 20 are led out from the same side of the housing 30, and the first lead-out terminal 11 and the second lead-out terminal 21 are mounted and matched with the locking mounting platform 320 on the same side of the housing 30. Two nuts 302 are integrated on the locking mounting platform 320 of the housing 30.
