The electronic product is fixed on the charging base by a magnetic attraction method so that the metal contacts abut against the elastic telescopic member from top to bottom. In this connection method, only a compression spring can be used as the elastic member to drive the elastic telescopic member to reset. After long-term use, the spring often ages, resulting in the inability of the elastic telescopic member to reset and causing poor contact. In view of this, the inventor has specifically proposed this application after studying the existing technologies. Summary of the Invention

[0013] As a further optimization, the first conductive part further has a connecting part connected to the first contact part and having elasticity, and the connecting part is used to drive the first contact part to protrude towards the charging slot.
[0014] As a further optimization, the first conductive part further has a limiting part connected to the first contact part, which is used to limit the protruding height of the first contact part.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:
[0032] As Figures 1 to 5 shown, in this embodiment, a charging connection structure includes:
[0033] A charging socket 2, which is electrically connected to a power source, includes a first housing 6 provided with a charging slot 12, a charging circuit assembly 9 disposed in the first housing 6, and a pair of first conductive members 8 disposed in the first housing 6 and electrically connected to the charging circuit assembly 9, and the first conductive member 8 has a first contact portion 13 located on the side wall of the charging slot 12;
[0034] A charging plug 1, which is disposed on an electrical product and electrically connected to the battery of the electrical product, the charging plug 1 includes a second housing 5 adapted to the charging slot 12, and a pair of second conductive members 4 disposed in the second housing 5, and the second conductive member 4 has a second contact portion 11 located on the side wall of the second housing 5;
[0035] The second housing 5 can be inserted into the charging slot 12 so that a pair of second conductive members 4 are respectively in electrical contact with a pair of first conductive members 8. Specifically, the second contact portion 11 is flush with the outer surface of the second housing 5, and the first contact portion 13 protrudes from the side wall of the charging slot 12 towards the inside of the charging slot 12. When the second housing 5 is inserted into the charging slot 12, the second contact portion 11 can abut against the first contact portion 13 and squeeze the first contact portion 13, causing the first conductive member 8 and the second conductive member 4 to be electrically connected. That is, through this simple connection method, the charging socket 2 can charge the electrical product equipped with the charging plug 1, and the contact effect between the first contact portion 13 and the second contact portion 11 can be effectively ensured by the side extrusion contact method, which has great practical significance. The charging circuit assembly 9 is a conventional technology and will not be elaborated here.
[0036] As Figure 3 shown, in this embodiment, the charging slot 12 gradually becomes larger from the bottom to the opening, and the second housing 5 gradually tapers towards its end. Specifically, the opening of the charging slot 12 is in the shape of a flared opening, and the end of the second housing 5 is provided with a chamfer, so that the second housing 5 can be more conveniently inserted into the charging slot 12. Further, the side wall of the charging slot 12 slopes from the bottom of the charging slot 12, so that the opening of the charging slot 12 is larger than the bottom of the charging slot 12, making the opening of the charging slot 12 in the shape of a flared opening. And the first contact portion 13 is arranged on the inclined side wall of the charging slot 12. When the second housing 5 is inserted into the charging slot 12, the squeezing force of the second contact portion 11 on the first contact portion 13 includes not only the squeezing force in the horizontal direction but also the gravity in the vertical direction, so a better electrical connection effect can be achieved.
[0037] As Figure 3 shown, in this embodiment, the charging plug 1 further includes a magnetic member 3 disposed on the second housing 5; the charging socket 2 further includes a metal member 7 disposed on the first housing 6 and capable of being adsorbed by the magnetic member 3. Specifically, the opening of the charging slot 12 is vertically upward. When the second housing 5 is inserted into the charging slot 12, there will be a self-locking effect due to the gravity. The magnetic member 3 is a cylindrical or toroidal magnet disposed inside the second housing 5, and a sheet-shaped metal member 7 capable of being adsorbed by the magnetic member 3 is provided below the charging slot 12 on the first housing 6, which can make the cooperation between the charging plug 1 and the charging socket 2 more firm. And because the side wall of the charging slot 12 is inclined, the magnetic attraction force is increased in the vertical direction, which can make the cooperation between the second contact portion 11 and the first contact portion 13 more tight, having great practical significance.
[0038] As Figure 3 、 Figure 4As shown, in this embodiment, the charging slot 12 is provided with trimming edges 16 for orientation. Specifically, the first groove has an inverted frustum shape and is provided with three tangent planes tangent to the circumferential surface of the frustum, and the three tangent planes are connected. Through holes for the first contact part 13 to extend out are provided on the tangent planes on both sides. This structure can effectively prevent the second housing 5 from rotating after being inserted into the charging slot 12, and the flat tangent planes can make the surface of the second housing 5 better fit on the side wall of the charging slot 12, making the contact between the second contact part 11 and the first contact part 13 more firm and reliable.
[0039] As shown by Figure 5 As shown, in this embodiment, the first conductive member 8 further has a connecting part 15 and a limiting part 14 respectively connected to the first contact part 13. The first contact part 13 is arc-shaped, can be flattened by extrusion, and reset after the external force is removed. The connecting part 15 has elasticity, and its two ends are respectively connected to the charging circuit assembly 9 and the first contact part 13, and can drive the first contact part 13 to extend out of the through hole of the tangent plane when not under force. The limiting part 14 can abut against the first housing 6 to limit the height of the first contact part 13 extending out of the side wall of the charging slot 12. Specifically, the two ends of the connecting part 15 are respectively connected to the first contact part 13 and the charging circuit assembly 9. When the first contact part 13 is extruded, it drives the connecting part 15 to swing, so that the first contact part 13 partially retracts into the through hole of the tangent plane. The middle of the connecting part 15 is arc-shaped, which can effectively buffer the metal fatigue caused by the bending during swinging. The limiting part 14 and the connecting part 15 are respectively connected to the upper and lower sides of the first contact part 13. When the connecting part 15 drives the first contact part 13 to swing towards the groove direction, the limiting part 14 can abut against the first housing 6 to prevent the end of the first contact part 13 from extending into the charging slot 12, so that the part of the first contact part 13 extending out of the tangent plane is arc-shaped, effectively ensuring the smoothness when the second housing 5 is inserted into the charging slot 12.
[0040] The charging circuit also has a USB or type-C female socket configured on the first housing 6, and an indicator light. The charging socket 2 further includes a counterweight block and a magnet 10 configured on the first housing 6, so that the charging socket 2 can be stably fixed on the table.
[0041] This application further provides a charging work lamp, which includes a work lamp main body and a charging base. The work lamp main body includes the charging plug 1 described in any of the above paragraphs. The charging base is the charging socket 2 described in any of the above paragraphs.
[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
