Summary of the invention

Advantages of the present invention will be further clarified below in conjunction with the specific embodiments and the accompanying drawings.

1 is a cross-sectional view of an embodiment of a switch device 10 of the present invention, wherein the switch device 10 is composed of a hollow switch body 13, a limiting member 11, a screw, and a pair of conductive elastic sheets 12. The limiting member 11 is hollow and inserted into the switch body 13. In the height direction or the upper and lower directions, a first gap 14 is disposed between the limiting member 11 and the inner sidewall of the switch body 13. The conductive elastic piece 12 is disposed in the first gap 14 and sandwiched between the switch main body 13 and the limiting member 11. Further, in the horizontal direction, a second gap is formed between the switch main body 13 and the upper surface 11a of the stopper. Snail The nail is inserted into the hollow portion of the stopper 11 and fixed by a nut such that the screw is movably coupled to the hollow portion, so that the switch device 10 can be rotated relative to the main body of the guide lamp. When the switch device 10 is closed, the conductive elastic piece 12 protrudes from a portion of the switch main body 13 and does not contact the guide rail. When the switch device 10 is opened, a part of the conductive elastic piece 12 of the protruding switch main body 13 contacts the guide rail, and the conductive elastic piece 12 and the guide rail There is an interference fit such that the rail exerts a pressure on it so that the conductive spring 12 produces a certain deformation and displacement. When the switching device 10 is closed again, the conductive elastic piece 12 is no longer in contact with the guide rail, thereby losing the pressure applied by the guide rail, at which time the conductive elastic piece 12 is restored to its original shape and position by its own elastic force.

2 is a perspective view of an embodiment of the conductive elastic piece 12 of the present invention, which includes a flat body portion 125 in a vertical plane, a fixed end 123 and a contact end 124 respectively located at the upper and lower ends of the main body portion 125. . The contact end 124 extends substantially perpendicularly from the upper end edge of the main body portion 125, and is partially sandwiched between the switch body 13 and the second gap formed by the limiting member 11 and partially protrudes from the outside of the switch device 10 for contacting the guide rail. The side of the contact end 124 that is in contact with the guide rail has a certain curvature, so that the conductive elastic piece 12 is cut into the guide rail to achieve an interference fit with the guide rail. The elastic portion 121 is disposed in the middle of the main body portion. When the conductive elastic piece 12 is pushed by the guide rail toward the limiting member 11, the elastic member 121 elastically deforms against the pushing member 11 and abuts against the limiting member 11 to generate a first elastic force. The first elastic force combined with the second elastic force generated by the deformation of the conductive elastic piece 12 itself causes the elastic force of the elastic element 121 to become large, and the elastic element 121 may be one or more. The more the elastic element 121 is, the more the elastic force is. Accordingly, the cooperation between the conductive elastic piece 12 and the guide rail is more compact. However, it should be noted that if the elastic force is too large, the guide rail may be deformed to some extent, and on the other hand, the force required to open the switching device 10 may become large, so that the switch device 10 is more difficult to open. The fixed end 123 is L-shaped and is used for connecting the wires. The conductive elastic piece 12 is fixed to the limiting member 11 through the fixing end 123. The fixed end 123 is provided with a sheet-like first fixing portion 1231 in the horizontal direction, and the first fixing portion 1231 The side is connected to the conductive elastic piece 12, and the free end thereof extends vertically downward to form a second fixing portion 1232. The switch body 13 and the limiting member 11 form a gap matching the size and shape thereof at a corresponding position of the fixed end 123 of the conductive elastic piece 12, so that the first fixing portion 1231 and the second fixing portion 1232 are disposed in the gap. The second fixing portion 1232 is further provided with At least one screw hole 1233 is connected to the power cable in the rail lamp. The screw hole 1233 can also be fixed to the limiting member 11 by a screw, or a screw hole 1233 is additionally provided, and the other screw hole 1233 is adopted. The conductive elastic piece 12 is fixed on the limiting member 11.

Preferably, the elastic element 121 has only one and is disposed at the center of the conductive elastic piece 12, because it is considered that the most effective elastic force to the conductive elastic piece 12 can be applied when it is disposed at the center, and the position of the center can make the entire conductive elastic piece 12 receive The balance of the force is stable, and the displacement is not caused by long-term use. It should be noted that the elastic member 121 can also be disposed at other positions in the middle of the conductive elastic piece 12, and when the conductive elastic piece 12 is pushed When squeezing, the position at which the elastic member 121 can reinforce the elastic force of the conductive elastic piece 12 by abutting against the stopper 11 is within the protection scope of the present invention.

Preferably, the elastic member 121 is in an interference contact with the limiting member 11 , that is, the distance from the main body portion 125 to the surface of the elastic member 121 facing the inner wall of the limiting member 11 is greater than or equal to the distance from the middle portion of the conductive elastic piece 12 to the limiting member 11 . With such a structure, the elastic member 121 and the limiting member 11 can fix the position of lateral movement between them by a certain elastic force, and avoid the conductive elastic piece when the switching device 10 is not opened (that is, when the conductive elastic piece 12 does not contact the guide rail). Unnecessary movement between the conductive elastic piece 12 and the stopper 11 caused by the looseness between the 12 and the casing.

As shown in FIG. 2 and FIG. 3, in a preferred embodiment of the present invention, the elastic member 121 may be a bent piece connected to the conductive elastic piece 12 at one end. The structure of the curved piece is considered to be simple in structure and at the same time satisfying the elastic force. The requirements, and the bending piece is not prone to metal fatigue under long-term force, and is particularly suitable as a spring device. The bent piece may have only one end connected to the conductive elastic piece 12 (that is, only one connecting end 1211). Such a structure is the simplest, but the relative elastic force generated is small, and is easily damaged by a large external force. The bent piece may also be connected to the conductive elastic piece 12 at both ends (that is, there are two connecting ends 1211). Such a structure is stronger than the former, and the elastic force generated is also larger, but the structure is more complicated than the former. Compared with the above two methods, the edge of the curved piece can also be connected to the conductive elastic piece 12, and the structure between the curved piece and the conductive elastic piece 12 is the strongest, and the elastic force is also the largest, but the production is also the most complicated, and at the same time The material of the conductive elastic piece 12 has certain requirements, and the cost of the conductive elastic piece 12 is increased to some extent. The elastic member 121 is preferably integrally formed from the main body portion of the conductive elastic piece 12, and may be formed in other achievable manners.

Preferably, the elastic member 121 is formed as a boss, and the structure of the boss is considered that the elastic member 121 needs to be in contact with the inner wall of the limiting member 11 to generate an elastic force, and the structure of the boss does not break to the limiting member on the one hand. The flatness of the inner wall of the eleventh, on the other hand, enables the force between the elastic member 121 and the inner wall of the stopper 11 to be more evenly distributed, thereby increasing the service life of the switching device 10.

Preferably, the conductive elastic piece 12 is provided with a through hole 122 corresponding to the elastic element 121. The through hole 122 cooperates with the elastic element 121 so that the elastic force generated by the elastic element 121 and the elastic force of the conductive elastic piece 12 due to deformation can be balanced. Therefore, the metal fatigue of the two is similar, so that the service life of the two is similar, so that the diameter of the through hole 122 can be changed according to the elastic force of the elastic member 121, so that the conductive elastic piece 12 is deformed and elasticized. Balanced.

FIG. 4 is a cross-sectional view of a guide lamp using the switch device of the present invention, which uses the guide lamp of the switch device 10, and further includes a locking device 40 for fixing the guide lamp main body 20 and emitting light. The portion 30 (such as a spotlight) prevents the light-emitting portion 30 from being loosened.

As shown in FIG. 5, the locking device 40 is composed of a matching first connecting ring 42 and a second connecting ring 43 sleeved on a connecting shaft 44. The first connecting ring 42 is connected to the rail lamp main body 20 and the second connecting end. The ring 43 is connected to the light-emitting portion 30. The two connecting rings have a 90-degree V-shaped groove 41. One end of the connecting shaft 44 is further provided with an axial fixing device, usually a nut, so that the first connecting ring 42 is connected to the second connecting ring 42. The rings 43 are in close contact with each other, so that the V-shaped groove 41 can be made such that when the first connecting ring 42 and the second connecting ring 43 are defined at the axial position of the connecting shaft 44 (i.e., when they are in close contact with each other), rotation does not occur. With the 90° V-groove 41, the resistance to the same is true whether it is clockwise or counterclockwise.
