The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0024] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the skilled person in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.
[0025] Reference Figures 1 to 5 As shown, it is a welding-free anti-falling patch terminal of the first embodiment of the technical solution, comprising: a ring frame 100, a limiting plate 200, an elastic buckle 300, wherein the inner passage of the ring frame 100 can pass through the pin of the to-be-patched element as an accommodation space for the pin of the to-be-patched element, and the to-be-patched element is taken as a DOB LED light source horizontal capacitor element 500, which has a metal pin 501 located on the side; the limiting plate 200 is vertically arranged at the top rear end of the ring frame 200, and has a first through hole 201 for the pin of the horizontal capacitor element 500 to pass through, which can prevent the pin of the horizontal capacitor element 500 from falling vertically; the elastic buckle 300 comprises a first buckle 310 and a second buckle 320 which are oppositely arranged on the left and right ends of the top of the ring frame 100 in the transverse direction, and the front ends of the first buckle 310 and the second buckle 320 are used to clamp the pin of the horizontal capacitor element 500 from the left and right sides to realize conductive connection, it should be pointed out that the ring frame 100 and the elastic buckle 300 are both metal conductive bodies, and the pin of the horizontal capacitor element 500 passes through the first buckle 310 and the second buckle 320, the ring frame 100 and the aluminum substrate 600 in sequence to realize conductive connection.
[0026] As Figure 1As shown, in some embodiments of this solution, the front ends of the first latching piece 310 and the second latching piece 320 are respectively provided with wire clamping grooves 301. The wire clamping grooves 301 are inverted triangular in shape with the flared opening located on the outside. The inverted triangular and flared wire clamping grooves 301 facilitate the insertion and clamping of the pins of the horizontal capacitor element 500, and at the same time have a limiting function to prevent them from running out of the front ends of the first latching piece 310 and the second latching piece 320, thus avoiding poor contact.
[0027] like Figure 1 , Figure 2 As shown, in some embodiments of this solution, the first latch 310 and the second latch 320 are both metal springs bent downwards towards each other. The bending positions of the first latch 310 and the second latch 320 are at the same height as the first through hole 201. The front ends of the first latch 310 and the second latch 320 are located between the first through hole 201 and the top of the annular frame 200. This height design facilitates the horizontal capacitor element 500's pins to bend laterally into the annular frame 200, making the structure compact and aesthetically pleasing.
[0028] Furthermore, in some embodiments of this solution, the bending positions of the first fastener 310 and the second fastener 320, as well as the four corner positions of the annular frame 100, are arc-shaped. The arc-shaped structure can prevent injury when touching a person's hand or other components.
[0029] like Figure 1 , Figure 2 As shown, the top of the limiting plate 200 is provided with an open extrusion groove 202. The bottom of the extrusion groove 202 is connected to the top of the first through hole 201 through a first gap 203. Compared with the installation method where the pins of the horizontal capacitor element 500 pass through the first through hole 201 and are then bent and inserted into the clamping groove 301, by opening the extrusion groove 202 and the first gap 203 on the top of the limiting plate 200, the pins of the horizontal capacitor element 500 can be bent in advance. During installation, the bent pins of the horizontal capacitor element 500 are directly inserted from top to bottom through the extrusion groove 202 and the first gap 203 into the first through hole 201 and simultaneously inserted into the clamping groove 301, which greatly improves the installation efficiency.
[0030] Furthermore, such as Figure 2 As shown, the limiting plate 200 is also provided with a second slot 204 extending from the bottom of the first through hole 201 to the annular frame 100. The second slot 204 and the first slot 203 are located on the center line of the vertical direction of the first through hole 201. With this design, the limiting plate 200 has a greater degree of flexibility, which makes it easier for the horizontal capacitor element pins to be squeezed into the extrusion groove 202 and the first slot 203 and then into the first through hole 201.
[0031] like Figure 1 , Figure 2As shown, the solderless, anti-detachment surface mount terminal of this solution also includes soldering pins 400. Soldering pins 400 are located at the bottom of the annular frame 100 and are used for soldering to the aluminum substrate 600. By specifically setting soldering pins 400 at the bottom of the annular frame 100, the connection process between the surface mount terminal and the aluminum substrate 600 is simplified and the structure is more reliable. It can be understood that after setting the soldering pins 400, the metal pins 501 of the horizontal capacitor element 500 are electrically connected to the aluminum substrate 600 sequentially through the first latch 310 and the second latch 320, the annular frame 100, and the soldering pins 400.
[0032] Furthermore, in some embodiments of this solution, there are two solder pins 400, which are respectively disposed at the bottom left and right ends of the annular frame 100. The two ends are respectively soldered to fix the patch terminal and the aluminum substrate 600, thereby further improving the structural stability and avoiding the patch terminal from falling off and poor contact.
[0033] like Figure 2 As shown, the two solder leads 400 are bent towards each other to a horizontal position with a gap at their front ends. This bending increases the contact area between the solder leads 400 and the aluminum substrate 600 during soldering, thereby improving structural stability and preventing surface mount terminals from detaching or causing poor contact. The gap at the front ends of the two solder leads 400 allows the horizontal capacitor element 500 leads to extend further downwards, such as... Figure 3 As shown, the aluminum substrate 600 has through holes, which allow the leads of the horizontal capacitor element 500 to be inserted into or below the aluminum substrate 600 when they are too long.
[0034] Furthermore, the ring frame 100, the limiting plate 200, the elastic buckle 300, and the welding pin 400 are integrally formed, which can improve production efficiency and reduce production costs.
[0035] As described above, this solution uses a limiting plate 200 and an elastic buckle 300, such as... Figure 4 , Figure 5 As shown, the horizontal component of the DOB LED light source can be fixed on the front of the aluminum substrate 600 using the surface mount terminals of this solution. Based on the dual functions of the horizontal clamping and fixing of the elastic buckle 300 and the vertical anti-detachment of the limiting plate 200, the capacitor is prevented from falling off and poor contact during transportation vibration, drops, etc.
