The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

The implementation mode is as follows:

as shown in fig. 1-5, the utility model discloses a SMD toggle switch, including casing 10, fitting member 102 and dial piece 20, fitting member 102 and casing 10 riveting and be equipped with terminal group 30, the one end of terminal group 30 is located casing 10, the other end of terminal group 30 is worn to locate fitting member 102 and can with the PCB board (not shown) tin soldering in order to paste on the PCB board, dial piece 20 activity locate in casing 10 and be provided with the lead-in part that can switch on with terminal group 30 to make dial piece 20 can remove and control circuit's break-make or switch in casing 10. Therefore, in the conventional surface-mounted toggle switch, the terminal group 30 is welded to the PCB and attached to the PCB, and in the process that the toggle block 20 toggles back and forth in the housing 10, the conduction part on the toggle block 20 is connected to the terminal group 30 to control the on/off or switching of the circuit. Because the housing 10 is not soldered to the PCB by solder pins, and is fixed to the PCB only by soldering the terminal set 30 at the bottom of the housing 10 to the PCB, there is a risk that the housing 10 is separated from a mating member riveted to itself during the process of toggling the toggle block 20 in the housing 10 to turn on or off the control circuit.

On the basis of the structure, the first welding leg 11 and the second welding leg 12 are arranged on the shell 10, the first welding leg 11 is positioned on a first side of the dial block 20 moving in the shell 10, and the second welding leg 12 is positioned on a second side of the dial block 20 moving in the shell 10. So, dial piece 20 when the in-process that makes a round trip to stir control circuit's break-make or switch in casing 10, can make casing 10 welded fastening on the PCB board under the effect of first leg 11 and second leg 12, dial piece 20 and possess the stress point at casing 10 internal movement direction's first side and second side, thereby can effectively avoid dialling piece 20 and make a round trip to stir control circuit break-make or switch in casing 10 and lead to casing 10 to break away from the risk with the fitting piece of self riveting, thereby can avoid toggle switch the bad phenomenon of circuit contact to appear in the use.

It should be noted that, the toggling block 20 toggles back and forth in the housing 10 to connect the positive and negative terminals of the terminal set to control the on/off of the circuit or switch the circuit in the conventional prior art in the technical field of toggle switches, and will not be described in detail here.

It should be noted that the inventor can reasonably change the number of the solder fillets according to the actual situation, and the invention is not limited thereto, and therefore, it is within the scope of the invention for a person skilled in the art to reasonably change the number of the solder fillets to solder the housing 10 on the PCB.

In this embodiment, a sliding groove 1011 communicating with the inner cavity of the housing 10 is formed on one side wall of the housing 10, the sliding groove 1011 is disposed along the direction in which the dial block 20 moves in the housing 10, the dial block 20 is provided with a dial grip 21, and the dial grip 21 is disposed through the housing 10 and can move in the sliding groove 1011 along with the movement of the dial block 20. Therefore, in order to facilitate the toggling of the toggle block 20, the toggle handle 21 is disposed on the toggle block 20, and the user can toggle the toggle handle 21 to move the toggle handle 21 in the sliding slot 1011 to switch the on/off of the control circuit.

In this embodiment, since the user uses the dial grip 21 to dial the dial block 20 to move back and forth in the housing 10 to control the on/off or switching of the circuit, the stress on the housing 10 is mainly concentrated on one side of the sliding slot 1011, and the first solder leg 11 and the second solder leg 12 are disposed on the same side of the dial grip 21, so as to further improve the connection performance between the housing 10 and the PCB and stabilize the housing 10 on the PCB. Further, first leg 11 is used for with the terminal group 30 of the welded terminal surface of PCB board be used for with the welded terminal surface parallel and level of PCB board, and similarly, second leg 12 is used for with the terminal group 30 of the welded terminal surface of PCB board be used for with PCB board welded terminal surface parallel and level, so can improve the roughness of casing 10 on the PCB board, prevent that the phenomenon of slope from appearing in casing 10.

In this embodiment, the first solder tail 11 and the second solder tail 12 are L-shaped structures, and the first solder tail 11 and the second solder tail 12 can be welded to the PCB conveniently by the L-shaped structures, so that the work efficiency is improved. Of course, in other embodiments, only the first solder tail 11 or only the second solder tail 12 may be provided in an L-shaped configuration, which is not limited herein, and the inventor may reasonably select the configuration according to the actual situation.

In this embodiment, the first solder tail 11 is integrally formed with the housing 10; the second leg 12 is integrally formed with the housing 10. Therefore, the utility model discloses SMD toggle switch's casing 10 can let casing 10 more firmly on the PCB board from taking the leg (first leg 11 and second leg 12), solves the hidden danger that casing 10 was peeled off and takes the loss for the customer.

In this embodiment, the dial block 20 and the dial grip 21 are integrally formed to form a dial handle, that is, the dial block 20 and the dial grip 21 are integrated, so as to avoid the assembly of the dial grip 21 and the dial block 20. To facilitate mounting of the toggle handle within the housing 10, the mating member 102 is riveted to the bottom of the housing 101. The rivet structure of the mating member 102 and the housing 101 is a conventional art of the toggle switch, and therefore will not be described in detail herein.

In this embodiment, a notch 10111 is provided at one side of the sliding groove 1011, and the notch 10111 is used for making the toggle handle 21 enter the sliding groove 1011, so it can be understood that, when the toggle handle is installed on the housing 10, the housing 101 and the fitting piece 102 are detached and separated, the toggle block 20 slides into the U-shaped groove 1012 of the housing 101 from one end of the housing 101, under the action of the notch 10111, the toggle handle 21 enters the sliding groove 1011, and finally, the fitting piece 102 is connected with the housing 101, so that the connection between the toggle handle and the housing 10 can be completed.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
