Description

Switch module

Technical Field

The present invention relates to a switch module, and more particularly, to a switch module of a push button switch.

Background

Push-button switches are used in a large number of various types of electrical equipment. The button switch utilizes the button to push the transmission mechanism, and then drives the movable contact to be connected with or disconnected from the stationary contact, thereby realizing the connection or disconnection of a circuit.

The button switch consists of a button head, a middle seat and a switch module. The switch module comprises a shell, a push rod, a moving contact assembly and a fixed contact assembly. The movable contact assembly and the fixed contact assembly can be contacted and separated by operating the push rod. At present, the fixing strength of a switch module adopting direct-plug wiring to a wire is not ideal.

Disclosure of Invention

The invention aims to provide a switch module which is beneficial to improving the strength of fixing a wire.

The invention provides a switch module which comprises a shell and a static contact assembly. The fixed contact assembly comprises a fixed contact body and an elastic sheet. The fixed contact body is fixedly arranged relative to the shell and is provided with a third convex edge extending along a third direction. The housing is provided with insertion holes penetrating in an insertion direction perpendicular to the third direction. The insertion hole is positioned at one side of the third rib along the insertion direction. The elastic sheet is in a sheet shape extending along a track perpendicular to the third direction. The elastic sheet comprises a fixed section and a contact section which are arranged continuously along the extending track. The fixed section is fixedly arranged relative to the shell. The contact section abuts against the third rib from a side of the third rib facing away from the insertion hole in the insertion direction under the action of the own elastic force. The wire inserted into the insertion hole in the insertion direction can be inserted and clamped between the third rib and the contact section.

The static contact assembly of the switch module clamps the wires through the third convex edges and the contact sections to fix the wires, so that the strength of fixing the wires is improved.

In another exemplary embodiment of the switch module, the stationary contact assembly further comprises a release. The release member is provided movable relative to the housing to release the wire clamped between the third rib and the contact section by pushing against the contact section. The housing is provided with a fixing column extending in a third direction. The contact section passes between the release member and the fixed post. In the process that the release piece releases the wire by pushing the contact section, the contact section is pushed by the release piece to be abutted against the fixed column. Whereby the deformation range of the contact section can be limited.

In a further exemplary embodiment of the switching module, the contact section comprises two contact sections arranged side by side in the third direction. The contact section is provided with a spacing groove between the two contact portions to enable the two contact portions to be deformed independently. The stationary contact assembly further includes two release members. Each release member is provided movable relative to the housing to be able to move against one of the contact portions to release a wire clamped between the third rib and the contact portion. Therefore, one static contact assembly can be independently plugged with two wires.

In yet another exemplary embodiment of the switch module, the stationary contact assembly further comprises a spacer. The partition plate is fixedly arranged relative to the shell. The separator is in a flat plate shape perpendicular to the third direction and is inserted into the spacing groove to separate the two contact portions. Therefore, two independent lead inserting spaces can be formed, and poor contact caused by misplug of leads can be avoided.

In a further exemplary embodiment of the switch module, the switch module is provided with a fixing structure. The fixing section is connected with the fixing structure to achieve fixing relative to the housing. The fixed structure is arranged on the fixed contact body, the partition board or the shell. The fixing structure is provided with a hook, and the fixing section is hung on the hook; or the fixing structure is provided with a connecting hole, and the fixing section is spliced in the connecting hole; or the fixing structure is arranged as an abutting block, and the fixing section abuts against the abutting block through self elasticity; or the fixing structure is arranged as a slot, the slot extends along the direction perpendicular to the third direction, and the fixing section is inserted into the slot along the extending direction of the slot. The structure is simple and convenient to assemble.

In a further exemplary embodiment of the switch module, at least a portion of the spacer and the stationary contact body is bent from a continuous sheet material. Thereby facilitating processing and increasing conductive contact area.

In a further exemplary embodiment of the switch module, the stationary contact assembly further comprises a support body. The release member is movably coupled to the support body. The supporting body and the static contact body are fixedly connected with the partition board. Thereby being convenient for the whole replacement during the maintenance.

In a further exemplary embodiment of the switch module, the switch module is provided with two stationary contact assemblies. The two stationary contact assemblies are arranged in mirror image along a plane parallel to the third direction.

In a further exemplary embodiment of the switching module, the housing has a channel which runs through in a first direction. The switch module also includes a push rod and a movable contact assembly. The push rod is movably arranged in the channel along the first direction and the opposite direction of the first direction. When the two switch modules which are at the same angle and are arranged along the first direction are in a combined relative position, the two push rods can mutually abut against each other along the direction parallel to the first direction, and when the two push rods mutually abut against each other, the push rods of the switch modules are in the same relative position with the shell. The movable contact assembly is connected with the push rod. The push rod is capable of driving the moving contact assembly to move from a separated position separated from the fixed contact assembly to a contact position contacting the fixed contact assembly by moving in a first direction relative to the housing, and capable of driving the moving contact assembly to move from the contact position to the separated position by moving in a reverse direction relative to the housing. Thereby, superposition linkage between the switch module and the switch module can be realized.

In a further exemplary embodiment of the switching module, the housing has a first latching hook and a second latching hook. The first clamping hook is arranged at one end of the shell along the first direction, and the second clamping hook is arranged at the other end of the shell along the first direction. Under the condition that the two switch modules are positioned at the combined relative positions, the first clamping hooks and the second clamping hooks at the opposite ends of the two switch modules along the first direction are mutually clamped so as to relatively fix the two switch modules. Thereby, the two switch modules in the combined relative position can be conveniently fixed.

In a further exemplary embodiment of the switch module, the switch module further comprises a first elastic element. The first elastic member is capable of applying an elastic force to the push rod that moves in a return direction parallel to the first direction with respect to the housing. The automatic reset of the push rod can be realized by arranging the first elastic piece.

In a further exemplary embodiment of the switch module, the movable contact assembly is movably arranged on the push rod in the first direction and in a direction opposite to the first direction. The switch module further includes a second elastic member. The second elastic piece can apply elastic force to the movable contact assembly, wherein the elastic force moves along the first direction relative to the push rod. The second elastic piece can play a buffering role when the movable contact assembly and the two fixed contact assemblies are in shooting.

In a further exemplary embodiment of the switch module, the movable contact assembly is held against the stationary contact assembly in a first direction and by the second elastic element at a first angle in a circumferential direction perpendicular to a second direction perpendicular to the first direction with the movable contact assembly in the contact position. The moving contact assembly and the fixed contact assembly are abutted against each other through the inner spherical segment surface and the outer spherical segment surface with equal diameters. Under the condition that the movable contact assembly is located at the separation position, the movable contact assembly abuts against the push rod along the first direction under the action of the second elastic piece and is maintained at a second angle in the circumferential direction perpendicular to the second direction through abutting against the push rod. The first angle differs from the second angle by no more than 10 degrees. Thereby friction cleaning of the contact site can be achieved.

In yet another exemplary embodiment of the switch module, the moving contact assembly includes a moving contact body and a moving contact fixedly disposed on the moving contact body. The movable contact head is used for contacting and conducting with the fixed contact assembly. The push rod is provided with an assembling groove penetrating along the second direction. The moving contact body penetrates through the assembly groove along the second direction and can slide in the assembly groove along the first direction and the opposite direction of the first direction. The moving contact body is flat and the plate surface is parallel to the second direction. The push rod comprises a first rib and a second rib. The first rib and the second rib are respectively arranged on the groove walls of the assembly groove in a protruding mode, wherein the groove walls are opposite to each other along a third direction, and the third direction is perpendicular to the first direction and the second direction. The first rib and the second rib both extend along the second direction and have a height difference along the first direction. Under the condition that the movable contact assembly is located at the separation position, two ends of the movable contact body along the third direction respectively lean against the first convex rib and the second convex rib so as to enable the movable contact assembly to be maintained at the second angle. The structure is simple and convenient to process.

In this document, "schematic" means "serving as an example, instance, or illustration," and any illustrations, embodiments described herein as "schematic" should not be construed as a more preferred or advantageous solution.

Herein, "first", "second", etc. do not indicate the degree of importance or order thereof, etc., but merely indicate distinction from each other to facilitate description of documents.

Nouns and pronouns for humans in this patent application are not limited to a particular gender.

For the sake of simplicity of the drawing, the parts relevant to the present invention are shown only schematically in the figures, which do not represent the actual structure thereof as a product.

Fig. 1 is a schematic diagram of an exemplary embodiment of a switch module. The switch module is used for a push button switch, for example, but not limited thereto. As shown in fig. 1, the switch module includes a housing 10, two stationary contact assemblies 30, a push rod 40, and a movable contact assembly 50. Two stationary contact assemblies 30 are disposed within the housing 10 and are mirror images of one another along a plane a.

The push rod 40 is movably disposed in the housing 10 along a first direction D1 and a direction opposite to the first direction D1. The first direction D1 is parallel to the plane a. The movable contact assembly 50 is disposed in the housing 10 and connected to the push rod 40.

Fig. 2 is a state diagram of a variation of the switch module shown in fig. 1. As shown in fig. 1 and 2, the push rod 40 can drive the moving contact assembly 50 from a separated position (i.e., the position shown in fig. 2) separated from the two stationary contact assemblies 30 to a contact position (i.e., the position shown in fig. 1) in contact with the two stationary contact assemblies 30 by moving in a first direction D1 relative to the housing 10 from the second position shown in fig. 2 to the first position shown in fig. 1, and can drive the moving contact assembly 50 from the contact position to the separated position by moving in a reverse direction relative to the housing 10 from the first position shown in fig. 1 to the second position shown in fig. 2. With the moving contact assembly 50 in the contact position, electrical conduction is achieved between the two stationary contact assemblies 30 through the moving contact assembly 50.

Fig. 3 is a schematic structural view of the stationary contact assembly shown in fig. 1. As shown in fig. 3, in the present exemplary embodiment, each of the stationary contact assemblies 30 includes one stationary contact body 31, one stationary contact 34, and one elastic piece 33. The stationary contact body 31 and the stationary contact 34 are made of a conductive material. The stationary contact body 31 is fixedly arranged relative to the housing 10 and has a third rib 311 extending in a third direction D3, wherein the third direction D3 is perpendicular to the first direction D1 and parallel to the plane a. The stationary contact body 31 is fixed to the housing 10 by, for example, inserting a plug thereto into the housing 10, but is not limited thereto. The fixed contact 34 is fixedly disposed on the fixed contact body 31 and is used for contacting and conducting with the moving contact assembly 50.

As shown in fig. 1, the housing 10 is provided with insertion holes 14 penetrating in an insertion direction S perpendicular to the third direction D3 for each stationary contact assembly 30 (each stationary contact assembly has an independent insertion direction S). The insertion hole 14 is located at one side of the third rib 311 in the insertion direction S. The insertion direction S forms an angle of, for example, 50 degrees with a second direction D2 perpendicular to the first direction D1 and the third direction D3.

As shown in fig. 3, the elastic piece 33 has a sheet shape extending along a trajectory perpendicular to the third direction D3. The spring 33 includes a fixed section 331 and a contact section 332 disposed in series along its extended path. The fixed section 331 is fixedly disposed with respect to the housing 10. The contact section 332 abuts against the third rib 311 from the side of the third rib 311 facing away from the insertion hole 14 in the insertion direction S under the action of its own elastic force.

As shown in fig. 4, the wire 91 inserted into the insertion hole 14 in the insertion direction S can push against the contact section 332 to elastically deform the contact section 332 so as to be inserted between the third rib 311 and the contact section 332 and be sandwiched by the third rib 311 and the contact section 332, and the wire 91 abuts against the third rib 311 to achieve contact conduction, thereby achieving quick connection of the wire 91.

The static contact assembly of the switch module clamps the wires through the third convex edges and the contact sections to fix the wires, so that the strength of fixing the wires is improved.

As shown in fig. 5, in the present exemplary embodiment, the stationary contact assembly 30 further includes a release 36. The release member 36 is provided movable relative to the housing 10 in the insertion direction S and in a direction opposite to the insertion direction S. As shown in fig. 5, the release member 36 is movable in the insertion direction S to push against the contact section 332 to elastically deform the contact section 332 to be separated from the wire 91, thereby releasing the wire 91 sandwiched between the third rib 311 and the contact section 332.

As shown in fig. 5, in the present exemplary embodiment, the housing 10 is provided with one fixing post 15 extending in the third direction D3 for each stationary contact assembly 30. The contact section 332 passes between the release member 36 and the fixed post 15. During the release of the wire by the release 36 by pushing against the contact section 332, the contact section 332 is pushed against the fixed post 15 by the release 36. Whereby the deformation range of the contact segment 332 can be limited.

Fig. 6 is an exploded view of a portion of the structure of the stationary contact assembly shown in fig. 1. As shown in fig. 6, in the present exemplary embodiment, the contact section 332 includes two contact portions 3321 disposed side by side in the third direction D3. Each contact portion 3321 abuts against the third rib 311 by its own elastic force. The contact section 332 is provided with a spacing groove 335 between the two contact portions 3321 to enable the two contact portions 3321 to be independently deformed. The housing 10 is provided with two insertion holes 14 arranged side by side in the third direction D3 for each stationary contact assembly 30. Each of the insertion holes 14 is opposite to one of the contact portions 3321 in the insertion direction S. Each stationary contact assembly 30 is provided with two release members 36 arranged side by side in the third direction D3. Each release piece 36 can release the wire sandwiched between the third rib 311 and one contact portion 3321 by moving against the contact portion 3321. Thereby, one stationary contact assembly 30 can be plugged with two wires independently.

As shown in fig. 3 and 6, in the present exemplary embodiment, each stationary contact assembly 30 further includes a spacer 37. The partition 37 is fixedly disposed with respect to the housing 10, and in the present exemplary embodiment, the partition 37 is fixedly connected to the stationary contact body 31, specifically, the partition 37 and the middle section of the stationary contact body 31 are formed by bending a continuous plate. The partition 37 has a flat plate shape perpendicular to the third direction D3 and is inserted into the spacing groove 335 to separate the two contact portions 3321. Therefore, two independent lead inserting spaces can be formed, and poor contact caused by misplug of leads can be avoided. Since the middle sections of the separator 37 and the stationary contact body 31 are formed by bending continuous plates, the separator 37 can improve the conductive contact area by contacting the inserted wires.

In the illustrated embodiment, the switch module is provided with one fixed structure for each stationary contact assembly 30. The fixed section 331 connects the fixed structure to achieve fixation relative to the housing 10. The fixed structure is provided to the stationary contact body 31, the partition 37, or the housing 10. Specifically, as shown in fig. 3 and 6, in the present exemplary embodiment, the fixing structure is provided as one hook F1. The hook F1 is provided to the partition 37. The fixing section 331 is hung on the hook F1 through a through hole provided therein. The structure is simple and convenient to assemble. But is not limited thereto.

Fig. 7 and 8 are used to illustrate another exemplary embodiment of a stationary contact assembly. In the exemplary embodiment shown in fig. 7 and 8, the fastening structure is provided as a slot F4. The slot F4 is disposed on the partition 37 and extends along a direction perpendicular to the third direction D3, and the fixing section 331 is inserted into the slot F4 along the extending direction of the slot F4. The structure is simple and convenient to assemble.

Fig. 9 and 10 are used to illustrate yet another exemplary embodiment of a stationary contact assembly. In the exemplary embodiment shown in fig. 9 and 10, the fixing structure is provided as one connection hole F2. The connection hole F2 is provided in the stationary contact body 31. A bent and tilted sheet-like plug formed at one end of the fixing section 331 is inserted into the connection hole F2. The structure is simple and convenient to assemble. In addition, in the exemplary embodiment shown in fig. 9 and 10, the stationary contact assembly 30 further includes a support 38. The release 36 is movably connected to the support 38. The supporting body 38 and the static contact body 31 are fixedly connected with the partition plate 37. Thereby being convenient for the whole replacement during the maintenance.

Fig. 11 and 12 are provided to illustrate yet another exemplary embodiment of a stationary contact assembly. In the exemplary embodiment shown in fig. 11 and 12, the fastening structure is provided as a slot F4. The slot F4 is disposed on the partition 37 and extends along a direction perpendicular to the third direction D3, and the fixing section 331 is inserted into the slot F4 along the extending direction of the slot F4. The stationary contact assembly 30 further includes a support 38. The release 36 is movably connected to the support 38. The supporting body 38 and the static contact body 31 are fixedly connected with the partition plate 37. Thereby being convenient for the whole replacement during the maintenance.

Fig. 13 is a schematic structural view of another exemplary embodiment of a switch module. As shown in fig. 13, the fixed structure of the switch module is provided as an abutment block F3. The abutment block F3 is provided to the housing 10. The fixed section 331 abuts against the abutment block F3 by self elastic force. The structure is simple and convenient to assemble.

In the exemplary embodiment shown in fig. 1, the housing 10 has a channel 13 which runs through in the first direction D1. The push rod 40 is movably disposed in the channel 13 along the first direction D1 and a direction opposite to the first direction D1.

The two switch modules which are at the same angle and are arranged along the first direction D1 can be combined with each other in a combined relative position. Fig. 14 and 15 show two switch modules in a combined relative position. As shown in fig. 14 and 15, with a reasonable dimensioning, with the two switch modules in the combined relative position, the two push rods 40 can abut against each other in a direction parallel to the first direction D1 and with the two push rods 40 abutting against each other the push rods 40 of the respective switch modules are in the same relative position with the housing 10. Specifically, in fig. 14, both push rods 40 are located at the first position, the upper push rod 40 is moved downward, and the lower push rod 40 moves synchronously under the pushing of the upper push rod 40, so that the relative positions of the push rods 40 of the switch modules and the housing 10 are the same. In fig. 15, both push rods 40 are located at the second position, the lower push rod 40 is moved upwards, and the upper push rod 40 moves synchronously under the pushing of the lower push rod 40, so that the relative positions of the push rods 40 of the switch modules and the housing 10 are the same. Thereby, the switch module realizes superposition linkage between the switch module and the switch module.

As shown in fig. 14 and 15, in the present exemplary embodiment, the housing 10 has two first hooks 11 and two second hooks 12. The first hook 11 is disposed at one end (i.e., the upper end in the drawing) of the housing 10 along the first direction D1. The second hook 12 is disposed at the other end (i.e., the lower end in the drawing) of the housing 10 along the first direction D1. As shown in fig. 14 and 15, in the case where the two switch modules are in the combined relative position, the first hooks 11 and the second hooks 12 at opposite ends of the two switch modules along the first direction D1 are engaged with each other to relatively fix the two switch modules. Thereby, the two switch modules in the combined relative position can be conveniently fixed. In other exemplary embodiments, the two switch modules in a combined relative position may also be secured by other structures, such as, but not limited to, by bolting.

Fig. 16 is a partial cross-sectional view of a portion of the structure along V-V in fig. 1. Fig. 17 is a partial cross-sectional view of a portion of the structure along VI-VI in fig. 2. As shown in fig. 16 and 17, in the present exemplary embodiment, the switch module further includes a first elastic member 81. The first elastic member 81 is capable of applying an elastic force to the push rod 40 that moves in a return direction parallel to the first direction D1 with respect to the housing 10. In the present exemplary embodiment, the reset direction is the same as the first direction D1, but not limited thereto, and in other exemplary embodiments, the reset direction may be opposite to the first direction D1. The first elastic member 81 is, for example, a compression spring. The automatic reset of the push rod can be realized by arranging the first elastic piece.

As shown in fig. 1 and 2, in the present exemplary embodiment, the movable contact assembly 50 is movably disposed on the push rod 40 along the first direction D1 and the opposite direction of the first direction D1. The switch module further comprises a second elastic member 82. The second elastic member 82 is capable of applying an elastic force to the movable contact assembly 50 with respect to the push rod 40 moving in the first direction D1. The second elastic member 82 is, for example, a compression spring. The second elastic piece can play a buffering role when the movable contact assembly and the two fixed contact assemblies are in shooting.

As shown in fig. 1, the moving contact assembly 50 includes a moving contact body 51 and two moving contacts 52 fixedly provided to the moving contact body 51. Each movable contact 52 is adapted to be in electrical contact with one of the stationary contact assemblies 30. The push rod 40 has an assembly slot 43 extending therethrough in the second direction D2. The movable contact body 51 is inserted into the fitting groove 43 along the second direction D2, and is slidable in the fitting groove 43 along the first direction D1 and a direction opposite to the first direction D1. The moving contact body 51 is flat and the plate surface is parallel to the second direction D2.

As shown in fig. 1 and 16, with the movable contact assembly 50 in the contact position, the movable contact assembly 50 abuts against the two stationary contact assemblies 30 in the first direction D1 and is maintained at a first angle in the circumferential direction perpendicular to the second direction D2 by abutting against the two stationary contact assemblies 30 by the second elastic member 82.

As shown in fig. 2 and 17, with the movable contact assembly 50 in the separated position, the movable contact assembly 50 abuts against the push rod 40 in the first direction D1 and is maintained at a second angle in the circumferential direction perpendicular to the second direction D2 by abutting against the push rod 40 by the second elastic member 82. Specifically, as shown in fig. 17, the push rod 40 includes a first rib 41 and a second rib 42. The first rib 41 and the second rib 42 are respectively protruded from the opposite groove walls of the fitting groove 43 in the third direction D3. The first rib 41 and the second rib 42 each extend in the second direction D2 and have a height difference in the first direction D1. With the movable contact assembly 50 in the separated position, both ends of the movable contact body 51 in the third direction D3 abut against the first and second ribs 41 and 42, respectively, to maintain the movable contact assembly 50 at the second angle.

The difference between the first angle and the second angle does not exceed 10 degrees, in particular the difference between the first angle and the second angle is for example 10 degrees. In the process of moving the moving contact assembly 50 from the separation position to the contact position, the moving contact assembly rotates from the second angle to the first angle after contacting the fixed contact assembly 30, so that friction is generated between the moving contact assembly and the fixed contact assembly 30, and a cleaning effect can be realized through friction. The moving contact assembly 50 and the fixed contact assembly 30 are abutted against each other, for example, by an inner spherical segment surface and an outer spherical segment surface with equal diameters, thereby facilitating improvement of the friction cleaning effect and increase of the contact area.
