[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1 The present invention discloses a welding-free indicator light, which mainly includes a light-emitting element 20, an indicator light body, and a cover 11 arranged at the end of the indicator light body. The indicator light body includes a top cover 12, a shell 10, and a nut buckle for facilitating the installation of the indicator light on a certain panel. The top cover 12 is connected to the top of the shell 10 by threading ( Figure 1 The cover 11 is disposed at the bottom of the housing 10 ( Figure 1 ).

[0041] Specifically, refer to Figure 2 As shown, in this embodiment, the light emitting element 20 can be a single LED lamp, a single light emitting diode, or a lamp bead matrix composed of multiple LED lamps or light emitting diodes, wherein the light emitting element 20 is disposed in the housing 10 and mounted on the top of the housing 10. The top cover 12 can be a colored light-transmitting material, that is, when the light emitting element 20 is illuminated, colored light can be presented through the top cover 12, and the color of the light is the same as the color of the top cover 12.

[0042] Reference Figure 3-Figure 4The bottom of the indicator light body is also provided with a terminal assembly 30, and two pins 21 of the light emitting element 20 pass through the terminal assembly 30 and are pressed onto the terminal assembly 30 through the cover 11. The terminal assembly 30 is used to connect an external wire, thereby conducting the light emitting element 20 with an external circuit.

[0043] Specifically, the bottom of the housing 10 is provided with a cavity 103 for accommodating the terminal assembly 30, the number of the terminal assembly 30 is two, and an integrally formed partition 105 is also provided in the middle of the cavity 103, and a circular connection hole 104 is also provided at the bottom of the cavity 103. The terminal assembly 30 is composed of a Z-shaped conductive plate 31 and a pressing plate 32, and the conductive plate 31 and the pressing plate 32 are fastened and assembled by bolts, that is, the external wire can be inserted between the conductive plate 31 and the pressing plate 32 and the two are pressed by bolts. The bottom of the housing 10 is provided with a circular opening, which is arranged to coincide with the connection hole 104, and the conductive plate 31 includes a bottom plate 311 connected to the housing 10, a bent plate 312 connected to the pin 21, and a connecting portion 313 connecting the bottom plate 311 and the bent plate 312, wherein the conductive plate 31 is an integrated structure, that is, the bent plate 312 is bent in two sections to form a Z-shaped structure.

[0044] The bent plate 312 is also provided with a through hole 3121 for connecting the pin 21. The pin 21 passes through the through hole 3121 and then bends downward. In order to press the pin 21 onto the bent plate 312, a vertical downward pressing block 117 is provided inside the cover 11. When the cover 11 is buckled onto the bottom of the housing 10, the pressing block 117 can firmly press the pin 21 onto the bent plate 312, thereby eliminating the subsequent welding steps and greatly improving the production efficiency of the product.

[0045] In particular, a hollow annular wall 314 is provided at the bottom of the bottom plate 311, and the annular wall 314 is fixed by being inserted into the cavity 103, that is, the annular wall 314 is inserted into the connection hole 104 in the cavity 103 for interference fitting. In order to further improve the connection strength between the conductive plate 31 and the cavity 103, and prevent the conductive plate 31 from being easily removed from the cavity 103 or loosened. A ring-shaped convex ring 3141 is also provided on the outer side of the annular wall 314, and its function is to increase the interference between the annular wall 314 and the connection hole 104 in the cavity 103, that is, it has a stop function to prevent the conductive plate 31 from falling off due to external force.

[0046] Further, refer to Figure 5-Figure 8 The pressing block 117 and the top cover 12 are an integrated structure, and the pressing block 117 is a rectangular block. A groove 1171 for limiting the pin 21 is provided on the bottom surface of the pressing block 117. The groove 1171 is a semicircular structure. It should be noted that the pressing block 117 can press the pin 21 in the radial direction (refer to Figure 7 ), or it can be pressed along the extension direction of the pin 21 (refer to Figure 8), the main purpose of the pressing block 117 is that when the top cover 12 is assembled with the housing 10, the top cover 12 can press the pin 21 to prevent its connection from loosening.

[0047] In order to further improve the connection effect of the pin 21, a positioning notch 3122 is also provided on the through hole 3121 of the bent plate 312. The function of the positioning notch 3122 is to clamp the pin 21 in an interference fit to prevent it from shaking left and right so as to improve the accuracy of the fit between the pressing block 117 and the pin 21. In particular, the positioning notch 3122 can be a V-shaped or U-shaped slot, and one end is connected to the through hole 3121. After the pin 21 of the light-emitting element 20 passes through the through hole 3121, it is inserted into the positioning notch 3122 and then bent 90°. The setting of the positioning notch 3122 also increases the positioning judgment of the automated equipment, so that the production of the indicator light can be more suitable for automated production.

[0048] Reference Figure 1 , Figure 7 , Figure 8 The cover 11 is also provided with a plug block 111 for easy assembly with the housing 10 and a clamp arm 115 for cooperating with the partition 105. Both sides of the plug block 111 are provided with protrusions 112 extending outward, and the housing 10 is provided with a slot 101 for cooperating with the plug block 111. The left and right side walls of the slot 101 are provided with a limit groove 102 for cooperating with the protrusion 112. In this embodiment, both sides of the protrusion 112 are also provided with a first bevel 113 and a second bevel 114.

[0049] Specifically, the first bevel 113 is arranged on the upper side of the protrusion 112, and its main function is to abut against the top of the limiting groove 102 to prevent the top cover 12 from being separated from the housing 10, and the second bevel 114 is used to facilitate the insertion of the plug 111. In order to achieve the above functions, the slope of the first bevel 113 is greater than the slope of the second bevel 114, and the slope of the first bevel 113 is about 45°-90°, while the slope of the second bevel 114 is about 0°-30°.

[0050] The clamping arm 115 that clamps the partition 105 is composed of two convex walls 116, and a gap 118 for placing the partition 105 is provided between the two convex walls 116. In order to further increase the connection strength between the clamping arm 115 and the partition 105, thereby further improving the connection strength between the cover 11 and the outer shell 10, the two ends of the convex wall 116 are inclined and extended into the gap 118, that is, the width of the gap 118 decreases with the increase of the length of the convex wall 116, that is, the clamping arm 115 and the partition 105 are interference fit.

[0051] Example 2

[0052] Reference Figure 9-10, discloses another solder-free indicator light, which is different from the technical solution disclosed in Example 1 in that a positioning groove 1051 for facilitating positioning is also provided on the partition 105, and the positioning groove 1051 is used to position the pin 21 of the light-emitting element 20. The positioning groove 1051 is a tower-shaped structure, and its groove width decreases with the increase of the groove depth, and the groove width at the bottom of the positioning groove 1051 is less than or equal to the width of the pin 21, and the pin 21 is determined by two-point positioning. In this embodiment, the pressing block 117 and the partition 105 are arranged parallel to each other, and the pressing block 117 is arranged on one side of the partition 105, and the pressing block 117 is also provided with a groove 1171 for limiting the pin 21.

[0053] The pressing block 117 and the pin 21 are arranged perpendicular to each other. In order to further improve the fixing effect of the pressing block 117 on the pin 21, the pressing block 117 is pressed at the front end of the pin 21, that is, after the pin 21 passes through the through hole 3121, it is bent 90° and stuck in the positioning groove 1051, and then the front end of the pin 21 is pressed by the pressing block 117. The length of the pressing block 117 can be slightly larger than or just enough to press the pin 21. If the length of the pressing block 117 is larger than the plane of the top surface of the bending plate 312, that is, it exceeds this plane, the pin 21 will be bent again, thereby increasing the connection strength between the pin 21 and the conductive plate 31.

[0054] It should be noted that the indicator light disclosed in Example 2 is partially identical to the technical solution disclosed in Example 1, and the differences have been disclosed in the above description.

[0055] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
