Description

  The present invention relates to a push button switch, and particularly refers to a positioning structure of a connecting leg inside the push button switch.

  Multi-command switches are now universally applied to various consumer electronics products including mobile phones, PDAs, computer keyboards, etc., and multi-command switches can generate multiple sets of circuit signals due to multi-stage change conduction effects. That allows many operations to be performed with a single switch, achieving the objective of reducing the assembly volume of the information product and still having the advantage of being convenient to use.

  Patent Document 1 The switch includes a base, the base has a hollow storage chamber that is open at the top, the storage chamber is provided with an electrode portion, and the electrode portion is provided with a spring, The spring is provided with a push button assembly including an upper push button and a lower push button, and a lid is disposed on the base for closing the storage chamber, and the lid has a watermark hole for protruding the upper push button. The upper push button has a support part and is limited in the storage chamber, and the upper push button is provided with a joining groove, and the lower push button is satisfied in the joining groove. The pressure receiving portion is positioned and does not exceed the positioning area of the joining groove, and a pressure control portion provided between the pressure receiving portion of the lower push button and the spring. The signal is generated because the pressure control portion presses the spring, and the spring is deformed to come into contact with the electrode portion to generate an electrical connection.

  Many of the existing circuit laying designs inside the switch are made by embedding the connection legs and the switch body and adopting the injection molding method. Must be able to generate many function signals. For example, in Patent Document 2, a single switch body must generate many different signal outputs at the same time, and more connection legs are embedded and ejected simultaneously. Since the circuit cloth station is extremely difficult, in Patent Document 3, the second connection leg inserted into the circuit cloth station is the most difficult, but the separation system is incorporated, but the second connection leg is bent to be a pressure contact step inside the switch body. And must be formed so as to be located at the contact step outside the switch body, but the overall volume of the switch body is rather small, so that Therefore, it is difficult to position when assembling the second connecting leg, or it is inadvertently touched when assembling and the second connecting leg is bent too much, and the pressure connection step is bent and the second connection is made. It is affected so that a false signal is generated from the leg.

In order to improve the situation where positioning cannot be performed well, the restriction of the activity of the connecting leg was submitted using the shape that can be combined with each other between the connecting leg and the base. A good positioning can be obtained depending on the shape.

  In order to achieve the above object, the second connecting leg installed on the insulating base of the push button switch includes a contact leg embedded in the base and a press contact stage located in the switch, and the switch is connected through a pressing operation. Since the second connection leg and the first connection leg of the member are electrically connected, and the bottom part of the position corresponding to the pressure contact step and the pressure contact step of the switch body all appear in the arc-shaped protrusion, The object of reliably positioning the press contact step at the bottom is achieved.

The invention of claim 1 includes a switch main body having a wiring space therein, and at least two first connection legs and second connection legs separately installed in the switch main body, and the two The connecting leg is provided with a connecting member that is normally connected to the first connecting leg, and the connecting member receives a force and presses against the second connecting leg to generate a signal output. The bottom of the main body is provided with a connection hole, and the second connection leg is provided with a contact leg step attached to the connection hole and a pressure contact step positioned between the connection member and the bottom of the switch main body. The bottom part of the position opposite to the press contact step of the main body appears as an arc-shaped protrusion, and the positioning structure of the connection leg of the push button switch is characterized in that the installation of the second connection leg is convenient.
The invention of claim 2 is the positioning structure of the connection leg of the push button switch according to claim 1, wherein a position limiting step is further extended to the other end of the press contact step of the second connection leg, and at the bottom of the switch body. The positioning structure of the connecting leg of the push button switch is characterized in that a position limiting hole is provided corresponding to the position limiting step.

  The connecting leg positioning structure described in the present invention solves the problem that the second connecting leg 40 is not always accurately restricted to the base 20 when the micro push button switch is manufactured. Since the connecting legs are installed, the operation of the wiring space 21 appears more important. In contrast, if the second connecting legs 40 are not accurately positioned, a problem of signal confusion occurs. If the connecting leg positioning structure of the present invention is used, the second connecting leg 40 can obtain a better positioning effect, and bending or shifting of the press contact step 42 can be avoided. In the situation where the space 21 is the least, an accurate signal can still be generated, and the quality of the switch is of course improved.

  1 and 2 disclose a perspective view and an exploded view of an optimal embodiment of a push button switch according to the present invention. As shown in the drawings, the present invention relates to a push button switch, and the switch body is a lid. 10 and the assembly of the base 20, the wiring body 21 is formed inside the switch body, and the first connection leg 60 and the second connection leg 40 are installed by the embedded injection method, Contact leg steps 41, 62 that are bent and separated and fixed to the switch body, and connection holes 22 provided in advance corresponding to the contact leg steps 41, 62 of the base 20, are provided. Is extended to the outside of the switch body and connected to an external signal source, and each connection leg is provided with press contact steps 42 and 61 on the surface of the table 20 in the wiring space 21. The features of the present plan are that the portions facing the pressure contact step 42 of the second connection leg 40 and the pressure contact step 42 of the second connection leg 40 of the switch body all appear on the arc-shaped protrusions, so the second connection leg 40 has this shape. The position on the switch body is limited by the combination of

  Further, the lid 10 is provided with a hole 11 and a push member 30 is installed, and a conducting contact member 50 is disposed between the push member 30 and the connecting leg, and the conducting contact member 50 may be a circular spring piece. Is connected to the pressure contact step 61 of the first connection leg 60 in a normal state at the contact part 52, and the central area is provided over the second connection leg 40 at the arc-shaped circular top part 51. In a state where the member 30 is not receiving a force, the push member 30 is moved near the circular top 51 of the guide member 50 by gravity, and the push member 30 is further provided with a position limiting portion 311, and the circular top 51 and the lid By limiting the position to 10, the push member 30 is restricted to the inside of the wiring space 21 and does not fall off from the switch body.

  3 and 4 Please refer to the operation display diagram of the present invention. As shown in the drawing, when the push member 30 receives a pushing operation, an operation of moving up and down occurs, which includes a push button 31 that receives the pushing operation and directly applies force to the push button 31. A stop button 32 is attached to the contact member 50 when the push button 31 is moved by force. FIG. 3 shows a state in which the push button is not pressed. In the pushing operation of FIG. 4, the push button 31 is moved downward so that the stop button 32 is pressed against the guide member 50. When the pressure control end 321 for pressing the contact portion 52 is provided and the stop button 32 is pressed against the push button 31, the pressure control end 321 stably presses the contact portion 52 of the connecting member 50 and the pressure contact step 61 of the first connection leg 60. And the circular top 51 is deformed and pressed against the pressure contact step 42 of the second connection leg 40. Both the pressure connection steps 42 and 61 of the second connection leg 40 and the first connection leg 60 are stabilized by this pressing operation each time. Electrical connection can be obtained, and the second connecting leg 40 and the first connecting leg 60 form an electrical connection between the two through the connecting member 50 to generate a signal. When the pushing operation is completed, the push member 30 receives no force and is restored to the original state by the guide member 50, and the push member 30 is pushed back to the original position, and at the same time, the first connecting leg 60 and The state of electrical continuity of the second connection leg 40 is released. Since this type of push button switch is quite small, the connecting legs 40, 60 are placed inside with an embedded injection method, and the second connecting leg 40 is located on the pressure contact stage 42 and the base 20 through the above-described design of the present invention. When the circular top 51 is pressed and deformed, the relative distance between the connecting member 50 and the second connecting leg 40 becomes small. Therefore, even if the deformation amount of the connecting member 50 is not so large, the circular top 51 can contact the press contact step 42 of the second connecting leg 40 to generate electrical connection, and by the pressing operation The error that occurs can be reduced.

  To further explain the positioning structure of the connecting leg of the present invention, please refer to FIG. 3 and the three-dimensional external view of the optimum embodiment of the second connecting leg 40 of the present invention. As shown in the drawing, the arc surface curvature of the arc-shaped projection of the pressure contact step 42 of the second connection leg 40 in the optimum embodiment is larger than the arc surface curvature of the arc-shaped projection of the bottom portion. When the press contact step 42 is arranged on the arcuate protrusion at the bottom, it does not shift horizontally, and the object of positioning the second connection leg 40 of the present invention at the bottom is achieved. This design is not limited to whether the pressure contact step 42 and the bottom arcuate protrusion are combined with each other. In FIG. 5, the arc surface curvature of the arcuate protrusion of the pressure contact step 42 of the second connection leg 40 is the bottom circle. Although equal to the arcuate curvature of the arcuate protrusion, it can also position the second connecting leg 40 at the bottom.

  In addition to this, as shown in FIGS. 2 and 3 again, in order to increase the position limiting effect of fixing the second connecting leg 40 on the base 20, the second connecting leg 40 may be further provided with a position limiting step 43. In addition, the position limiting step 43 can be embedded in the position limiting hole 23 provided relative to the position limiting step 43 of the base 20 to increase the position limiting effect of the second connection leg 40. If the optimum installation position is formed by two-point positioning at the relative position of the contact leg step 41, the second connection leg 40 can obtain a better positioning effect.
