Description

Technical Field

[0001] This utility model relates to a switching device, and more particularly to a tactile switch with a semi-enclosed bracket. Background Technology

[0002] A tactile switch is a common type of electronic switch that allows for the instantaneous switching of a circuit by pressing a button. It is characterized by its small operating force, high sensitivity, and tactile feedback, and is widely used in electronic devices.

[0003] Existing tactile switches generally consist of a bracket and a base mounted on the bracket. The base and bracket are typically connected by riveting plastic posts. Specifically, plastic posts are placed on the base, and corresponding holes are provided on the bracket. During assembly, the plastic posts are inserted into the holes, and a process such as heat riveting deforms the posts to form a rivet head locking structure. When the force applied by pressing the button vertically is excessive, such as 1 kg (≈9.8 N), since most tactile switches are designed to withstand operating forces of ≤5 N, the plastic posts at the riveting point may break or detach. This causes the bracket to separate from the base, and the internal springs and contacts of the base may shift, resulting in the tactile switch failing to conduct properly and malfunctioning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tactile switch with a semi-enclosed bracket. The bracket forms a semi-enclosed structure that hugs the base. When the force of pressing the button vertically is large, it can prevent the plastic column at the riveting point from breaking or falling off, prevent the bracket from separating from the base, and prevent the tactile switch from malfunctioning.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A tactile switch with a semi-enclosed bracket includes a bracket and a base mounted on the bracket. The bracket includes a front end plate and semi-enclosed side plates that bend backward from the middle of the left and right ends of the front end plate. The front end plate has several positioning holes. The rear end of the semi-enclosed side plates bends inward to form a snap-fit ​​wide plate, and the lower end of the semi-enclosed side plates is integrally provided with a vertically downward support plate. The front end face of the base has several positioning posts spaced apart. The positioning posts pass through the positioning holes and the protruding ends are formed into limiting rivet heads by hot riveting. The left and right edges of the rear end face of the base have positioning grooves along the height direction. The positioning grooves have openings near the outer sidewalls. The snap-fit ​​wide plate extends into the positioning grooves from the openings and abuts against the bottom of the positioning grooves.

[0007] In some embodiments, the semi-enclosed side panel is bent backward 90° from the middle of the left and right ends of the front panel, and the buckle wide plate is bent inward 90° from the rear end of the semi-enclosed side panel.

[0008] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0009] When assembling the base and bracket of this utility model, the positioning pin on the base passes through the positioning hole of the front plate, and the protruding end of the positioning pin is processed into a limiting rivet head by a hot riveting process; then, the rear ends of the semi-enclosed side plates on the left and right sides of the front plate are bent inward to form a snap-fit ​​wide plate. The snap-fit ​​wide plate extends into the positioning groove and abuts against the bottom of the positioning groove. The snap-fit ​​wide plate is a widened structure to increase the contact area. The snap-fit ​​wide plate and the positioning groove can further limit the base. The bracket as a whole forms a semi-enclosed structure that hugs the base. When the force of pressing the button vertically is large, it can prevent the plastic pin at the riveting point from breaking or detaching, prevent the bracket from separating from the base, and prevent the tactile switch from malfunctioning.

However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of this application more complete and to fully convey the concept of the present application to those skilled in the art.

[0015] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0016] like Figures 1-3As shown, the tactile switch of the semi-enclosed bracket provided in this application embodiment includes a bracket 1 and a base 2 mounted on the bracket 1; the bracket 1 includes a front end plate 11 and a semi-enclosed side plate 12 that bends backward from the middle of the left and right ends of the front end plate 11. The front end plate 11 is provided with a plurality of positioning holes 111. The rear end of the semi-enclosed side plate 12 bends inward to form a fastening wide plate 121, and the lower end of the semi-enclosed side plate 12 is integrally provided with a vertically downward support plate 3. The semi-enclosed side plate 12 is formed by bending backward only from the middle of the left and right ends of the front end plate 11, which can save materials; the front end face of the base 2 is provided with a plurality of positioning posts 4 at intervals. The positioning posts 4 pass through the positioning holes 111 and the protruding ends are formed into limiting rivet heads 41 by hot riveting. The left and right edges of the rear end face of the base 2 are provided with positioning grooves 21 along the height direction. The positioning grooves 21 are provided with openings on the side walls near the outside. The fastening wide plate 121 extends into the positioning grooves 21 from the openings and abuts against the bottom of the positioning grooves 21. A button 7 is movably mounted on the base 2, and the button 7 extends out of the front panel 11.

[0017] When assembling the base 2 and the bracket 1 of this utility model, the positioning post 4 on the base 2 passes through the positioning hole 111 of the front end plate 11, and the protruding end of the positioning post 4 is processed into a limiting rivet head 41 by a hot riveting process; then the rear ends of the semi-enclosed side plates 12 on the left and right sides of the front end plate 11 are bent inward to form a snap-fit ​​wide plate 121. The snap-fit ​​wide plate 121 extends into the positioning groove 21 and abuts against the bottom of the positioning groove 21. The snap-fit ​​wide plate 121 is a widened structure to increase the contact area. The snap-fit ​​wide plate 121 and the positioning groove 21 can further limit the base 2, so that the bracket 1 forms a semi-enclosed structure that hugs the base 2 as a whole. When the force of pressing the button 7 vertically is large, it can prevent the plastic post at the riveting point from breaking or falling off, prevent the bracket 1 from separating from the base 2, and prevent the tactile switch from malfunctioning. Moreover, this utility model has a simple structure and is easy to assemble.

[0018] Specifically, the semi-enclosed side panel 12 is bent backward at 90° from the middle of the left and right ends of the front panel 11, and the buckle-position wide panel 121 is bent inward at 90° from the rear end of the semi-enclosed side panel 12.

[0019] The upper and lower ends of the positioning groove 21 form limiting shoulders 211. The limiting shoulders 211 cooperate with the fastening wide plate 121 to provide coarse vertical positioning of the base 2.

[0020] The rear end of the support plate 3 protrudes from the rear end face of the base 2, and a clearance opening 5 is provided between the support plate 3 and the buckle wide plate 121. The lower end of the clearance opening 5 is set as an inclined surface 51. By setting the lower end as an inclined surface 51 to the clearance opening 5, when the rear end of the semi-enclosed side plate 12 is bent inward to form the buckle wide plate 121, the buckle wide plate 121 can be avoided, which facilitates the assembly process.

[0021] The support plate 3 has a pin 31 at its lower end. The pin 31 is vertically downward and plate-shaped. The pin 31 can be soldered onto the circuit board as a grounding pin to ground the bracket 1. The pin 31 of the tactile switch is also designed as a vertical plate shape, which facilitates the mounting of the tactile switch onto the PCB board using an SMT machine via tape reel. The base 2 has several conductive terminals, and the conductive terminals have terminal pins 6 that extend vertically downward from the base 2. The terminal pins 6 are used to solder onto the circuit board to achieve the electrical connection between the tactile switch and the circuit.

[0022] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
