Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, in particular to a travel switch capable of reducing electric ionization. Background Art

[0002] Electrical switches, especially travel switches, are widely used in various fields. However, most of the existing travel switches are peristaltic travel switches, that is, as the actuating rod moves, the distance between the static contact and the moving contact changes slowly. This will cause strong electric ionization between the moving contact and the static contact, resulting in a large arc, and shortening the service life of such travel switches.

[0003] In addition, the opening and closing of the existing travel switches rely on the movement of the actuating rod. During the movement of the actuating rod, the actuating rod inevitably collides with the main body part. A relatively large noise will be generated during the collision. The existence of the noise will increase the noise of its application environment. Summary of the Utility Model

[0035] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0036] Referring Figures 1 to 11 , a travel switch according to a preferred embodiment of the present utility model will be described in detail below. Specifically, the travel switch can be used for connection with external circuits, so that the on / off of the external circuit can be achieved through the on / off of the travel switch.

[0037] The travel switch includes a general substrate 10, a moving contact assembly 20, and at least a pair of static contact assemblies 30. The general substrate 10 has a top 11 and a bottom 12. A main installation groove 101 is formed between the top 11 and the bottom 12 of the general substrate 10 for installing the moving contact assembly 20, and a through groove 102 is formed in the middle of the top 11. The through groove 102 is arranged to communicate with the main installation groove 101, so that the main installation groove 101 can communicate with the outside through the through groove 102.

[0038] Furthermore, static installation parts 103 are respectively formed on the left and right sides of the general substrate 10 to form a pair of the static installation parts 103, and the static installation parts 103 on the left and right sides of the general substrate 10 are symmetrical to each other.

[0039] Furthermore, a communication gap 104 is respectively formed on the upper and lower sides of each static installation part 103 close to the main installation groove 101, and each communication gap 104 is arranged to communicate with the main installation groove 101. As shown in the figure, a first communication gap 104A is formed on the upper side of each static installation part 103 of the general substrate 10 close to the main installation groove 101, and a second communication gap 104B is formed on the lower side close to the main installation groove 101.

[0040] Preferably, a plurality of pairs of the static mounting portions 103 are symmetrically formed between the top 11 and the bottom 12 of the general substrate 10, and the plurality of pairs of symmetrically arranged static mounting portions 103 are spaced between the top 11 and the bottom 12.

[0041] In a preferred embodiment, four pairs of the static mounting portions 103 are symmetrically formed between the top 11 and the bottom of the general substrate 10. More preferably, the four pairs of static mounting portions 103 are equidistantly arranged between the top 11 and the bottom 12.

[0042] It is worth mentioning that each static connection component 30 includes a static contact piece 31, and the static contact piece 31 includes a fixing portion 311 and a static contact portion 312. The fixing portion 311 is mounted on the static mounting portion 103, and the static contact portion 312 is arranged to extend into the main mounting groove 101 through one of the communication gaps 104 on the upper and lower sides of the static mounting portion 103 on the general substrate 10. That is to say, the static contact portion 312 is either arranged to pass through the first communication gap 104A of the general substrate 10 or arranged to pass through the second communication gap 104B of the general substrate 10, so as to form a pair of static contacts at symmetric positions in the main mounting groove 101.

[0043] Specifically, the fixing portion 311 is arranged to extend along the plane direction of the general substrate 10, and the contact portion is arranged to extend from the end of the fixing portion 311 in a direction perpendicular to the plane of the substrate 10 and cross the corresponding communication gap 104, and then enter the main mounting groove 101.

[0044] Preferably, the static connection component 30 further includes a fixing member 32, and the fixing portion 311 of each static contact piece 31 is arranged to be fixed to the static mounting portion 103 through the fixing member 32.

[0045] Specifically, in one embodiment, the fixing portion 311 is provided with a first through hole 31101, the fixing member 32 includes a screw 321, and a threaded hole 105 is provided at a position of the static mounting portion 103 of the general substrate 10 corresponding to the first through hole 31101. After the screw 321 is arranged to pass through the first through hole 31101, it is threadedly connected to the threaded hole 105, so that the static contact piece 31 is threadedly fixed to the general substrate 10.

[0046] Preferably, the fixing member 32 further includes a nut 322, and the nut 322 is buried in the static mounting portion 103 to form the threaded hole 105.

[0047] Furthermore, the fixing member 32 further includes an auxiliary conductive sheet 33, and the auxiliary conductive sheet 33 is disposed above the fixing portion 311 of the static contact sheet 31. A second through hole 3301 aligned with the first through hole 31101 is also formed in the middle of the auxiliary conductive sheet 33. The nut 322 is disposed through the second through hole 3301 and the first through hole 31101 and then is threadedly connected to the threaded hole 105.

[0048] It is worth mentioning that, in the present utility model, since both the first through hole 31101 and the second through hole 3301 are set as light holes instead of threaded holes, during the subsequent process of rotating the nut 322, the static contact sheet 31 has good stability and is not easily rotated along with the rotation of the nut 322, thereby effectively ensuring the stability of the position of the static contact on the static contact sheet 31.

[0049] Those skilled in the art can understand that since the static contact sheet 31 can be arbitrarily installed in the first communication gap 104A and the second communication gap 104B, the travel switch can be made into travel switches of different models. Especially when the travel switch includes multiple pairs of the static connection components 30.

[0050] More specifically, the moving connection component 20 includes a moving contact member 21 and an actuating rod 22. The moving contact member 21 includes a moving contact piece 211, and moving contacts are respectively formed at positions on both sides of the moving contact piece 211 opposite to the static contacts. In addition, a through window 21101 is formed in the middle of the moving contact piece 211.

[0051] The actuating rod 22 is disposed in the main installation groove 101, and one end thereof can be connected to an external power component through the through groove 102.

[0052] It is worth mentioning that when the actuating rod 22 is driven by the power component, it can slide in the main installation groove 101 relative to the general substrate 10 along the axial direction defined by the extension direction of the actuating rod 22 itself. The actuating rod 22 is disposed through the through window 21101 of the moving contact piece 211 installed in the main installation groove 101.

[0053] The dynamic electric contact component 21 also includes at least one pair of instantaneous components 212, wherein each of the instantaneous components 212 includes a driving arm 2121 and a force storage elastic member 2122, wherein one end of the driving arm 2121 of one instantaneous component 212 in each pair of the instantaneous components 212 is rotatably connected to a side wall of one side forming the through window 21101, and the other end is rotatably connected to the side wall of the actuating rod 22, and the extension direction of the driving arm 2121 forms an angle of predetermined size with the axial direction; and one end of the driving arm 2121 of the other instantaneous component 212 is rotatably and connected to the other side wall forming the through window 21101, and is symmetrical with the driving arm 2121 of the instantaneous component 212 on one side relative to the axial direction.

[0054] The force storage elastic member 2122 is sleeved on the driving arm 2121 in an elastically deformable manner, so that when the driving arm 2121 rotates, the force storage elastic member 2122 has different elastic potential energies through its own expansion and contraction.

[0055] Those skilled in the art will appreciate that when the actuating rod 22 slides along the axial direction and the sliding stroke is large enough, the driving arm 2121 will rotate due to the destruction of the balance state of the force storage elastic member 2122, thereby causing the driving arm 2121 to drive the moving contact piece 211 to move instantaneously.

[0056] In other words, when the sliding stroke of the actuating rod 22 along the axial direction is less than the stroke required to overcome the rotation of the driving arm 2121 of the instantaneous member 212 to drive the instantaneous movement of the moving contact piece 211, even if the actuating rod 22 moves, the moving contact on the moving contact piece 211 is still not connected to the static contact piece 31. Until the sliding stroke of the actuating rod 22 along the axial direction is greater than the stroke required to overcome the rotation of the driving arm 2121 of the instantaneous member 212 to drive the instantaneous movement of the moving contact piece 211, the moving contact on the moving contact piece 211 is instantly connected to the static contact piece 31, so that the arc generated during creeping can be avoided.

[0057] In another preferred embodiment, the travel switch includes at least two dynamic contact members 21, wherein each dynamic contact member 21 is disposed between the top 11 and the bottom 12. At the same time, the travel switch also includes at least two pairs of static contact components 30 correspondingly.

[0058] refer to Figures 8 - 10, More preferably, among the plurality of moving contact members 21 arranged along the axial direction of the actuating rod 22, the strokes for driving the instantaneous movement of the moving contact piece 211 by overcoming the rotation of the driving arm 2121 of the instantaneous movement member 212 increase in sequence. That is to say, in one embodiment, when the actuating rod 22 moves a first distance, among the plurality of moving contact members 21 arranged along the axial direction of the actuating rod 22, the driving arm 2121 of the nearest first instantaneous movement member 212 rotates to drive the instantaneous movement of the moving contact piece 211 to conduct with the corresponding static contact, while the other moving contact pieces 211 remain disconnected from the static contact. When the actuating rod 22 moves another first distance, among the plurality of moving contact members 21 arranged along the axial direction of the actuating rod 22, the driving arm 2121 of the second instantaneous movement member 212 rotates to drive the instantaneous movement of the moving contact piece 211 to conduct with the corresponding static contact. At the same time, the moving contact piece 211 connected to the driving arm 2121 of the first instantaneous movement member 212 remains conducting with the static contact, while the other moving contact pieces 211 remain disconnected from the static contact. The subsequent moving contact members 21 and the static contact piece can be instantaneously conducted step by step as the actuating rod 22 moves.

[0059] Reference Figure 8 and Figure 11 , In another embodiment, among the plurality of moving contact members 21 arranged along the axial direction of the actuating rod 22, at least one moving contact member 21 has a smaller stroke for driving the instantaneous movement of the moving contact piece 211 by overcoming the rotation of the driving arm 2121 of the instantaneous movement member 212 than that of a moving contact member 21 on the left side, and a larger stroke than that of a moving contact member 21 on the right side for driving the instantaneous movement of the moving contact piece 211 by overcoming the rotation of the driving arm 2121 of the instantaneous movement member 212. In this way, as the actuating rod 22 moves, the moving contact piece 211 in at least one moving contact member 21 is conducted earlier than the moving contact piece 211 of a contact assembly 30 on the left side, and is conducted later than the moving contact piece 211 of a moving contact member 21 on the right side, so as to form a spare wiring mechanism, and thus cross instantaneous movement can be realized.

[0060] Furthermore, the actuating rod 22 has a head 221 and a tail 222, wherein the tail 222 extends in a radial direction to form a stopper 223. In addition, the universal base plate 10 forms a stopper 13 at a position corresponding to the stopper 223 of the actuating rod 22 in the main mounting groove 101, wherein the stopper 13 is arranged to extend from a housing forming the universal base plate 10 to a predetermined height in a vertical direction perpendicular to the universal base plate 10.

[0061] After the moving contact member 21 and the actuating rod 22 are mounted on the universal substrate 10, the side of the stopper 223 of the actuating rod 22 facing the head 221 is partially abutted against the side of the stopper 13 away from the head 221. It can be understood by those skilled in the art that, in this way, when the actuating rod 22 is driven to move, the stopper 13 can limit it.

[0062] The dynamic connection assembly 20 includes a return spring 23, and the actuating rod 22 is resettably limited in the main installation groove 101 of the universal base plate 10 by the return spring 23. It is worth mentioning that one end of the return spring 23 is abutted against the stopper 223 of the tail 222, and the other end is abutted against the universal base plate 10, and the return spring 23 is installed in the universal base plate 10.

[0063] It is worth mentioning that the head 221 of the actuating rod 22 is arranged to at least partially extend beyond the through slot 102 of the top 11 and out of the main mounting slot 101 of the universal base plate 10, and the cross-sectional size of the formed through slot 102 is just equal to the cross-sectional size of the main body of the actuating rod 22 located between the head 221 and the tail 222, so as to limit the position of the actuating rod 22 close to the head 221 to ensure that the actuating rod 22 can keep sliding in the axial direction when being driven to slide.

[0064] Furthermore, the universal base plate 10 forms a limiting platform 14, wherein the limiting platform 14 forms a through slot 1401, and the through slot 1401 is coaxially arranged with the through slot 102. The cross-sectional dimension of the through slot 1401 is equal to the cross-sectional dimension of the main body portion of the actuating rod 22 close to the tail portion 222, so as to limit the position of the actuating rod 22 close to the tail portion 222, so as to ensure that the actuating rod 22 can keep sliding in the axial direction when being driven to slide.

[0065] It is worth mentioning that at least one sound-absorbing groove 224 is provided on the side of the stop portion 223 close to the top portion 11. The sound-absorbing groove 224 can reduce the impact area between the stop portion 223 and the limit platform 14, thereby effectively reducing noise. It is worth mentioning that the position where the sound-absorbing groove 224 is provided is opposite to the limit platform 14.

[0066] More preferably, a partition block 15 is formed on the general substrate 10 by extending in the vertical direction perpendicular to the general substrate 10 at the middle part of the main installation groove 101 close to the static installation portion 103 and between the two communication gaps 104 on the upper and lower sides of the static installation portion 103. In this way, the moving contact piece 211 of the moving contact member 21 can also be blocked by the partition block 15 and be in an open state.

[0067] In this way, the moving contact member 21 and the actuating rod 22 can be arranged as required, so that the moving contact piece 211 of the moving contact member 21 can be electrically connected to the upper and lower static contact pieces 31 when being touched and reset. The moving contact piece 211 of the moving contact member 21 can also be electrically connected to the upper or lower static contact piece 31 when being touched or reset, and be in contact with the upper or lower partition block 15 in another state. In this way, the general substrate 10 can be adapted to manufacture a travel switch of type ZA or type ZB, and can also be used to manufacture other types of switches. In this way, the manufacturing cost can be greatly saved.

[0068] Furthermore, the travel switch further includes a housing 40, and the housing 40 is arranged to cover the notch of the main installation groove 101.

[0069] Preferably, a plurality of stop feet 41 are integrally extended from the housing 40, and each stop foot 41 is arranged at the communication gap 104 where the static contact piece 31 is not installed. Those skilled in the art can understand that in this way, it can effectively prevent external dust and conductive chips from entering the main installation groove 101 through the communication gap 104.

[0070] In a preferred embodiment, a magnet mounting groove 107 is formed between two of the communication gaps 104 on the static mounting portion 103 and near the side wall of the main mounting groove 101 and between the partition blocks 15. At least one magnet 50 is mounted in each magnet mounting groove 107. Specifically, the magnetic pole direction of the mounted magnet 50 is set to a transverse direction perpendicular to the extending direction of the actuating rod 22. In this way, when an electrically ionized arc is generated between the static contact piece 31 and the moving contact piece 211, the corresponding arc will be affected by the magnetic force and be extinguished to the general substrate 10 or the housing 40.

[0071] More importantly, since the magnetic pole direction of the mounted magnet 50 is set to a transverse direction perpendicular to the extending direction of the actuating rod 22, when wiring a pair of the static contact pieces 31, it is not necessary to consider the positive and negative poles of the wiring.

[0072] In this way, the permanent magnet can effectively reduce the arc generated when the static contact piece 31 and the moving contact piece 211 are in contact.

[0073] In a modified embodiment, each magnet mounting groove 107 can be separately formed on the static mounting portion 103 between two of the communication gaps 104 and near the side wall of the main mounting groove 101.

[0074] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the principle, the embodiments of the present invention can have any deformation or modification.
