[0002] LED light strips are products assembled using surface-mount LEDs on a strip-shaped FPC (flexible printed circuit board) or PCB rigid board. Depending on actual needs, LED light strips can be cut into any length. After cutting, it is necessary to re-solder wires on the light strip or solder power terminals to the LED light strip to enable power supply, which is cumbersome and inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a contact-type power-conducting plug with simple structure, good power-conducting stability, and wide applicability to LED light strips of various lengths. It also provides LED lighting fixtures that use the power-conducting plug.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A contact-type energized plug includes a plug body, a power cord, and an electrode plate. The plug body has a formed insertion portion with a receiving groove inside. The electrode plate passes through the receiving groove and is electrically connected to the power cord. The electrode plate includes an integrally formed riveting portion, a limiting portion, and an elastic bending portion. The riveting portion is crimped to the power cord. The limiting portion is fitted into the receiving groove. There is a vertical movement gap between the elastic bending portion and the limiting portion. The elastic bending portion has at least one set of contact protrusions for contacting and energizing an LED light strip.

[0006] As a further improvement to the above technical solution:

[0007] The insertion part is provided with a positioning through hole that communicates with the receiving groove, and the limiting part is provided with an anti-disengagement spring piece, which abuts against the inner wall of the positioning through hole.

[0008] The receiving groove is provided with an inclined surface to facilitate the insertion of the anti-detachment spring into the positioning through hole.

[0009] The inner walls on both sides of the receiving groove are provided with inner extended baffles, and the two sides of the limiting part are provided with abutting walls, which abut against the inner extended baffles.

[0010] The riveting part includes a riveting sheath and a riveting core. The riveting sheath is crimped to the sheath of the power cord, and the riveting core is crimped to the core of the power cord.

[0011] The plug body has a plug hole that communicates with the receiving groove, and the electrode plate passes through the plug hole into the receiving groove.

[0012] An LED lamp includes a housing and an LED light strip disposed within the housing, wherein the end of the housing is plugged into and connected to the aforementioned contact-type power-conducting plug.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. This utility model's contact-type energized plug includes a plug body, a power cord, and an electrode plate. The electrode plate is inserted into the receiving groove and electrically connected to the power cord. The electrode plate includes a riveting part, a limiting part, and an elastic bending part. There is an upper and lower movable gap between the elastic bending part and the limiting part. The elastic bending part is provided with an electrical contact protrusion. During the process of inserting the plug body into the LED lamp, the elastic bending part can undergo elastic deformation, avoiding hard contact between the electrical contact protrusion and the LED lamp, which would lead to deformation and poor contact. Under the elastic restoring force of the elastic bending part, the electrical contact protrusion and the flat wire on the LED light strip are always pressed tightly in contact, realizing energization. It has the advantages of simple structure, convenient and quick use, and good energization stability. Thus, the LED light strip can be cut into any length without direct contact lighting without wire bonding, meeting the needs of various length specifications of LED light strips, and has a wide range of applications.

[0015] 2. The LED lamp of this utility model has a contact-type power plug inserted into the end of the housing. The electrical connection is achieved by the electrode plate in the plug contacting the LED light strip, eliminating the soldering step, realizing the separation of the lamp wire, and making the installation and disassembly process convenient and quick, with high maintenance efficiency.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5As shown, the contact-type power-conducting plug of this embodiment includes a plug body 1, a power cord 2, and an electrode plate 3. The plug body 1 has a plug portion 101 formed therein, and a receiving groove 102 is provided in the plug portion 101. The electrode plate 3 passes through the receiving groove 102 and is electrically connected to the power cord 2. The electrode plate 3 includes an integrally formed riveting portion 301, a limiting portion 302, and an elastic bending portion 303. The riveting portion 301 is riveted to the power cord 2. The limiting portion 302 is fitted into the receiving groove 102. There is an upper and lower movable gap between the elastic bending portion 303 and the limiting portion 302. The elastic bending portion 303 is provided with at least one set of power-conducting protrusions 3031 for contacting and energizing the LED light strip. This contact-type energized plug includes a plug body 1, a power cord 2, and an electrode plate 3. The electrode plate 3 is inserted into the receiving groove 102 and electrically connected to the power cord 2. The electrode plate 3 includes a riveting part 301, a limiting part 302, and an elastic bending part 303. There is an upper and lower movable gap between the elastic bending part 303 and the limiting part 302. The elastic bending part 303 is provided with an electrical contact protrusion 3031. During the process of inserting the plug body 101 into the LED lamp, the elastic bending part 303 can undergo elastic deformation to avoid the electrical contact protrusion 3031 from hard contact with the LED lamp, which would cause deformation and poor contact. Under the elastic restoring force of the elastic bending part 303, the electrical contact protrusion 3031 and the flat wire on the LED light strip are always pressed tightly in contact, realizing power supply. It has the advantages of simple structure, convenient and quick use, and good power supply stability. Thus, the LED light strip can be cut into any length without the need for wire bonding and direct contact lighting, meeting the needs of various length specifications of LED light strips and having a wide range of applications.

[0029] Preferably, the insertion part 101 is provided with a positioning through hole 103 communicating with the receiving groove 102, and the limiting part 302 is provided with an anti-detachment spring piece 3021. The anti-detachment spring piece 3021 abuts against the inner wall of the positioning through hole 103, which can prevent the electrode piece 3 from moving out in the horizontal direction in the receiving groove 102, effectively improving the connection stability between the electrode piece 3 and the plug body 1.

[0030] Preferably, the receiving groove 102 is provided with an inclined surface 104 to facilitate the insertion of the anti-detachment spring piece 3021 into the positioning through hole 103, so that the operator can insert the electrode piece 3 into the plug body 1 more smoothly and easily, avoid the anti-detachment spring piece 3021 from breaking due to excessive stress, and effectively improve assembly efficiency.

[0031] Preferably, the inner walls on both sides of the receiving groove 102 are provided with inner extended baffles 105, and the two sides of the limiting part 302 are provided with abutment walls 3022. The abutment walls 3022 abut against the inner extended baffles 105, which not only prevents the electrode sheet 3 from falling out of the receiving groove 102, but also prevents the electrode sheet 3 from rotating in the receiving groove 102, and prevents the electrical connection protrusion 3031 from shifting and causing poor contact with the LED light strip, thereby further improving the connection stability of the electrode sheet 3 in the plug body 1.

[0032] Preferably, the riveting part 301 includes a riveting sheath 3011 and a riveting core 3012. The riveting sheath 3011 is riveted to the sheath of the power cord 2, and the riveting core 3012 is riveted to the core of the power cord 2. This can effectively improve the connection stability between the power cord 2 and the electrode sheet 3 and extend the service life.

[0033] Preferably, the plug body 1 has an insertion hole 106 that communicates with the receiving groove 102, and the electrode sheet 3 passes through the insertion hole 106 into the receiving groove 102.

[0034] like Figures 6 to 9 As shown, the LED lamp of this embodiment includes a housing 4 and an LED strip 5 disposed within the housing 4. The end of the housing 4 is connected to the aforementioned contact-type power plug. This LED lamp has a contact-type power plug inserted into the end of the housing 4. Electrical connection is achieved through the contact between the electrode plate 3 in the plug and the LED strip 5, eliminating the need for soldering, separating the lamp wires, and making installation and disassembly convenient and quick, resulting in high maintenance efficiency.

[0035] In this embodiment, Figures 6 to 9 Four styles of LED lamps are provided. It can be understood that the specific structure of the contact-type power-conducting plug and the LED lamps using the power-conducting plug of this utility model can vary and is not limited to the above embodiments.

[0036] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
