Description

Technical Field

[0001] This utility model relates to the field of switch technology, and more specifically, to a slide switch. Background Technology

[0002] The prior art discloses a slide switch, including: a lower housing and an upper housing, the lower housing and the upper housing forming a rectangular housing assembly, the housing assembly containing a stationary contact component and a moving contact component, the upper housing slidably having a switch element for driving the moving contact component to contact or separate from the stationary contact component; wherein, the lower housing has a latching part protruding on each of its two outer side walls along its length, and the upper housing has a slot that mates with the latching part on its two side plates along its length, the slot penetrating upward through the upper wall plate of the upper housing, and the dimension of the slot along the width direction of the upper housing is greater than the thickness dimension of the side plate so that the slot is set through along the thickness direction of the corresponding side plate, that is, the slot can be injection molded by upper and lower mold closing, without the need to set a lateral sliding slider on the injection mold, which simplifies the injection mold and allows more upper housings to be injection molded at one time in an injection mold of equal volume, thereby improving the production and processing efficiency of the slide switch.

[0003] In the aforementioned sliding switch, the stationary contact assembly includes a first conductive sheet and a stationary conductive element fixed to the first conductive sheet, and the moving contact assembly includes a second conductive sheet and a moving conductive element fixed to the second conductive sheet. The second conductive sheet has a protrusion, and the lower end face of the switch element has multiple pressing portions corresponding to the protrusions. During installation, the first and second conductive sheets are first fixedly installed on the lower housing, and then the upper housing, which houses the switch element, is pressed down and fastened to the lower housing. When the switch element is in the working position (i.e., at least one pressing portion corresponds to a protrusion), if the upper housing is directly fastened to the lower housing, the upper housing will cause the switch element to move downwards, resulting in the protrusion being subjected to the downward impact force of the pressing portion. This causes the protrusion to deform beyond its elastic limit, causing the moving conductive element to lift and deform upwards, leading to poor contact or no power supply during use. Furthermore, when the assembled slide switch is installed into other components, if the switch is squeezed, the protrusion may be subjected to the downward impact of the pressing part, causing the protrusion to deform beyond its own elasticity. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed. By setting corresponding support columns and extension sections, the protrusion will not be impacted or deformed when the sliding switch is assembled, thus ensuring good contact between the moving contact and the stationary contact.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A slide switch includes a base and a cover connected vertically to the base. The base has a stationary contact with a stationary contact and a movable contact with a movable contact. At least two stationary and two movable contacts are provided, with the movable contacts positioned higher than the stationary contacts. Each movable contact has a protrusion. A switch element is slidably mounted on the cover. The lower end face of the switch element has multiple pressing portions corresponding to the protrusions. The pressing portions can press downward against the corresponding protrusions to cause the movable contact to swing downward until the movable contact contacts the stationary contact. The switch element has multiple operating positions. When the switch is in any working position, at least one pressing part abuts against the corresponding protrusion. A support column is provided on the base corresponding to the position of each protrusion. Each pressing part is provided with an extension section. The extension section is provided in a one-to-one correspondence with the support column so that when the pressing part abuts against the protrusion, the extension section presses against the support column to limit the displacement of the pressing part in the direction of the moving contact, thereby preventing the protrusion from exceeding its own elastic deformation. The support column is located on one side of the protrusion and is set lower than the protrusion. The extension section extends from the pressing part to a side perpendicular to the sliding direction of the switch.

[0006] By adopting the above technical solution, when the switch is in the neutral position, one of the handle's pressing parts rests against the corresponding protrusion. At this time, if the cover with the switch is directly assembled to the base vertically, the support column on the base and the extension on the pressing part ensure that, within the protrusion's allowable elastic deformation range, the extension presses against the support column after the pressing part rests against the protrusion. This prevents the protrusion from being subjected to the impact force generated by the cover being assembled to the base, effectively preventing the impact deformation of the protrusion caused by directly assembling the cover and base when the switch is in the neutral position, which could lead to the moving contact tilting upwards and poor or no contact with the stationary contact, resulting in no power supply. Furthermore, when the slide switch is installed in other components, it will not cause impact deformation to the protrusion. The support column is located on one side of the protrusion and is set lower than the protrusion, ensuring that when the cover and base are assembled and in normal use, the pressing part abuts against the protrusion, and the moving contact contacts the stationary contact. The extension section extends from the pressing part to a side perpendicular to the sliding direction of the switch. Specifically, the extension section is integrally formed with the pressing part, that is, the side of the pressing part is lengthened to form the extension section. This facilitates the manufacturing and forming of the extension section and ensures that the position of the extension section corresponds with the support column.

[0007] Preferably, the base is provided with multiple position grooves along its length, and the switch is connected to a position positioning member that can enter any position groove through an elastic member. The position positioning member enters the position groove so that the switch is in one of the position working positions.

[0008] By adopting the above technical solution, the switch can be positioned in one of the working positions by moving the position positioning component in the position groove. This is mainly to increase the operating feel and to keep the position fixed after the switch slides. The switch is specifically provided with a groove for accommodating the elastic component and the position positioning component. During assembly, the elastic component (which can be a spring) and the position positioning component (which can be a bead that matches the position groove) are first assembled into the groove of the switch, and then the cover and base are assembled.

[0009] Preferably, the cover is provided with a guide groove arranged along its length, and the switch has a lever that is slidably disposed in the guide groove.

[0010] By adopting the above technical solution, the guide groove enables the switch to slide relative to the cover, while the toggle block facilitates the user's sliding operation of the switch.

[0011] Preferably, the cover is fastened to the base, the base is provided with a snap-fit ​​part, and the cover is provided with a slot corresponding to the snap-fit ​​part.

[0012] By adopting the above technical solution, the cover is specifically fastened to the base in the vertical direction. During the actual assembly, the cover is pressed down so that the fastening part is located in the slot, thus completing the fastening of the cover and the base.

[0013] Preferably, both the stationary contact and the moving contact extend outward from the base, and the base is provided with a first receiving groove for accommodating the stationary contact and a second receiving groove for accommodating the moving contact.

[0014] By adopting the above technical solution, the first receiving groove and the second receiving groove can be used to install the stationary contact piece and the moving contact piece respectively, thereby improving assembly efficiency.

[0015] Preferably, a limiting block is provided on the base at the position of the first receiving groove, and there is a gap between the limiting block and the first receiving groove. The stationary contact piece is inserted into the gap and its displacement in the height direction is limited by the limiting block.

[0016] By adopting the above technical solution, when installing the stationary contact piece, the stationary contact piece is placed into the first receiving groove and the end of the stationary contact piece is inserted into the gap to complete the positioning of the stationary contact piece. At this time, the limiting block can limit the stationary contact piece.

[0017] Preferably, the movable contact is located in the second receiving groove and forms a gap between it and the side wall of the base, and the support column is located in the gap.

[0018] By adopting the above technical solution, there is a gap between the moving contact piece and the side wall of the base, providing a position for the support column. Specifically, the support column is also integrally formed on the side wall of the base.

[0019] Preferably, the base is provided with a positioning post at the position of the second receiving groove to position the moving contact piece, and the cover is provided with a first pressing part that presses against the moving contact piece and a second pressing part that presses against the stationary contact piece.

[0020] By adopting the above technical solution, the positioning post can play a positioning role when installing the moving contact piece. The first pressing part and the second pressing part can press against the moving contact piece and the stationary contact piece respectively after the cover is connected to the base, ensuring the positional stability of the moving contact piece and the stationary contact piece.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, a sliding switch includes a housing 100, which includes a base 1 and a cover 2 vertically connected to the base 1. The base 1 has a stationary contact 3 with a stationary contact 31 and a movable contact 4 with a movable contact 41. At least two stationary contact 3s and two movable contact 4s are provided, with the movable contact 4 positioned higher than the stationary contact 3. Each movable contact 4 has a protrusion 42. A switch element 5 is slidably mounted on the cover 2. The lower end face of the switch element 5 has multiple pressing portions 51 corresponding to the protrusions 42. The pressing portions 51 can press downward against the corresponding protrusions 42 to cause the movable contact 4 to swing downward until the movable contact 41 contacts the stationary contact 31, thus activating the switch. The component 5 has multiple working positions. When the switch component 5 is in any working position, at least one pressing part 51 abuts against the corresponding protrusion 42. A support column 11 is provided on the base 1 corresponding to the position of each protrusion 42. Each pressing part 51 is provided with an extension section 52. The extension section 52 is provided in a one-to-one correspondence with the support column 11 so that when the pressing part 51 abuts against the protrusion 42, the extension section 52 presses against the support column 11 to prevent the protrusion 42 from exceeding its own elastic deformation. The support column 11 is located on one side of the protrusion 42 and is set lower than the protrusion 42. The extension section 52 extends from the pressing part 51 to the side perpendicular to the sliding direction of the switch component 5.

[0025] By adopting the above technical solution, when the switch 5 is in the working position, a pressing part 51 of the handle will abut against the corresponding protrusion 42. At this time, if the cover 2 with the switch 5 is directly assembled and connected to the base 1 in the vertical direction, the extension 52 will press against the support post 11 on the base 1 and the extension 52 on the pressing part 51 after the pressing part 51 abuts against the protrusion 42. Within the elastic deformation range allowed by the protrusion 42 itself, the extension 52 will press against the support post 11, so that the protrusion 42 will not be subjected to the impact force generated by the cover 2 being assembled onto the base 1. This effectively prevents the impact deformation of the protrusion 42 caused by directly assembling the cover 2 and the base 1 when the switch 5 is in the working position, which would cause the moving contact 41 to tilt upwards and make poor or no contact with the stationary contact, resulting in no power supply. Furthermore, when the slide switch is installed in other components, it will not cause impact deformation to the protrusion 42. The support column 11 is located on one side of the protrusion 42 and is positioned lower than the protrusion 42, ensuring that when the cover 2 and the base 1 are assembled and in normal use, the pressing part 51 abuts against the protrusion 42, and the moving contact contacts the stationary contact. The extension section 52 extends from the pressing part 51 to a side perpendicular to the sliding direction of the switch 5. Specifically, the extension section 52 is integrally formed with the pressing part 51, that is, the side of the pressing part 51 is lengthened to form the extension section 52. This facilitates the manufacturing and forming of the extension section 52 and ensures that the extension section 52 corresponds to the position of the support column 11.

[0026] The base 1 has multiple stop grooves 12 along its length. The switch 5 is connected to a stop positioning member 54 via an elastic member 53, which can enter any of the stop grooves 12. The stop positioning member 54 enters the stop groove so that the switch 5 is in one of the stop working positions. The movement of the stop positioning member 54 in the stop groove 12 allows the switch 5 to be in one of the stop working positions. This is mainly to improve the operating feel and to keep the position fixed after the switch 5 slides. The switch 5 is specifically provided with a groove for accommodating the elastic member 53 and the stop positioning member 54. During assembly, the elastic member 53 (which can be a spring) and the stop positioning member 54 (which can be a bead adapted to the stop groove 12) are first assembled into the groove of the switch 5, and then the cover 2 and the base 1 are assembled.

[0027] The cover 2 is provided with a guide groove 21 arranged along its length direction, and the switch 5 has a toggle block 55 slidably disposed in the guide groove 21. The guide groove 21 enables the switch 5 to slide relative to the cover 2, while the toggle block 55 facilitates the user to slide the switch 5.

[0028] The cover 2 is fastened to the base 1. The base 1 is provided with a latching part 13, and the cover 2 is provided with a corresponding groove 22. Specifically, the cover 2 is fastened to the base 1 in the vertical direction. During assembly, the cover 2 is pressed down, so that the latching part 13 is located in the groove 22, thus completing the fastening of the cover 2 and the base 1.

[0029] Both the stationary contact 3 and the moving contact 4 extend outward from the base 1. The base 1 is provided with a first receiving groove 6 for accommodating the stationary contact 3 and a second receiving groove 7 for accommodating the moving contact 4. The first receiving groove 6 and the second receiving groove 7 can be used to install the stationary contact 3 and the moving contact 4 respectively, thereby improving assembly efficiency.

[0030] Furthermore, a limiting block 61 is provided on the base 1 at the position of the first receiving groove 6, and a gap 62 is provided between the limiting block 61 and the first receiving groove 6. The stationary contact piece 3 is inserted into the gap 62 and its displacement in the height direction is limited by the limiting block 61. When installing the stationary contact piece 3, the stationary contact piece 3 is placed into the first receiving groove 6 and the end of the stationary contact piece 3 is inserted into the gap 62 to complete the positioning of the stationary contact piece 3. At this time, the limiting block 61 can limit the stationary contact piece 3.

[0031] The movable contact 4 is located in the second receiving groove 7 and forms a gap 71 with the side wall of the base 1, and the support column 11 is located in the gap 71. With this arrangement, there is a gap 71 between the movable contact 4 and the side wall of the base 1, which provides a position for the support column 11. Specifically, the support column 11 is also integrally formed on the side wall of the base 1.

[0032] In addition, a positioning post 72 is provided on the base 1 at the position of the second receiving groove 7 to position the movable contact piece 4. The cover 2 is provided with a first pressing part 23 that abuts against the movable contact piece 4 and a second pressing part 24 that abuts against the stationary contact piece 3. The positioning post 72 can play a positioning role when the movable contact piece 4 is installed. The first pressing part 23 and the second pressing part 24 can press against the movable contact piece 4 and the stationary contact piece 3 respectively after the cover 2 is fastened to the base 1, ensuring the positional stability of the movable contact piece 4 and the stationary contact piece 3.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
