Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an electrical connector for an LED lamp. Background Technology

[0002] LED tubes are currently one of the main lighting fixtures used in home and commercial lighting. In existing LED tubes on the market, the light source board and driver power supply are basically connected by soldering electrical wires. This method of electrical connection has poor reliability, with problems such as poor soldering and high defect rates. Furthermore, the process is complex and inefficient. This connection also leaves the other end of the driver power supply in a movable state, making it prone to abnormal noises if the entire lamp is subjected to external force and shakes. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an electrical connector for LED lights that is simple in structure and easy to assemble. When applied to LED lights, it can realize a reliable connection between the light source board and the driving power supply.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An electrical connector for an LED lamp includes an electrical connector body. The electrical connector body includes an insulating base with a through-hole connection slot on the insulating base. A conductive metal sheet is disposed within the insulating base. The conductive metal sheet has a first electrical connection portion and a second electrical connection portion. The first electrical connection portion is located within the insulating base and disposed in the connection slot. An insertion gap is provided between the first electrical connection portion and the inner top surface of the connection slot for the electrical connection end of a light source board or driver board of the LED lamp to be inserted and for the electrical connection portion on the electrical connection end of the light source board or driver board to be in close contact with the first electrical connection portion to achieve electrical connection. The second electrical connection portion extends out of the insulating base and is disposed outside the insulating base for close contact with the electrical connection portion on the electrical connection end of the driver board or light source board to achieve electrical connection. A connector is provided on the insulating base for stably mounting the electrical connector body on the driver board or light source board.

[0005] The insulating base is provided with a positioning seat for positioning and installing the conductive metal sheet. The upper part of the positioning seat is provided with the connecting slot. The positioning seat is provided with a positioning groove with a front and top opening. The main body of the conductive metal sheet is fixed in the corresponding positioning groove. The first electrical connection part extends upward from the top opening of the positioning groove and is disposed in the connecting slot. The second electrical connection part extends outward from the front opening of the positioning groove and is disposed outside the insulating base.

[0006] The bottom inner end face of the positioning groove is a horizontal positioning surface, the rear wall surface of the positioning groove is a vertically set limiting surface, the main body of the conductive metal sheet includes a horizontally set positioning resting part, the positioning resting part is positioned and rested on the horizontal positioning surface, the rear end of the positioning resting part is bent upward vertically to form a first limiting part that cooperates with the limiting surface, and the first limiting part abuts against the limiting surface. The top end of the first limiting part is bent upwards at an angle to form an angled bending part. The angled bending part is inclined from back to front and upwards. The angled bending part is disposed in the connecting slot. The end of the angled bending part is bent downwards to form a first bending part. The connection part between the angled bending part and the first bending part constitutes the first electrical connection part. The front end of the positioning and resting part is bent downwards vertically to form a second limiting part. The second limiting part abuts against the front end surface of the insulating base, and the end of the second limiting part is bent horizontally to form the second electrical connection part.

[0007] The positioning and resting part has barbed protrusions with a horizontal cross-section of a triangle on its left and right side surfaces, and the width of the barbed protrusions gradually decreases in the left and right direction.

[0008] The positioning groove has recessed guide grooves with front openings on its left and right sides, and the first limiting part has protruding guide blocks on its left and right sides, with the guide blocks set in the corresponding guide grooves.

[0009] The front opening of the guide groove is a guide opening, and the width of the guide opening gradually decreases from front to back in the vertical direction.

[0010] The connector includes an integrally formed welding part and a mounting part. The bottom end face of the welding part is a welding end face for welding onto the driver board or light source board of the LED lamp. The front end face of the mounting part extends toward the rear end face of the insulating base and is provided with mounting pins.

Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] Example 1: As shown in the figure, an electrical connector for an LED lamp includes an electrical connector body, which includes an insulating base 1. The insulating base 1 has a through-hole connection slot 11. A conductive metal sheet 2 is disposed inside the insulating base 1. The conductive metal sheet 2 has a first electrical connection portion 210 and a second electrical connection portion 220. The first electrical connection portion 210 is located inside the insulating base 1 and disposed in the connection slot 11. There is an insertion gap 111 between the first electrical connection portion 210 and the top inner end face of the connection slot 11 for the electrical connection end of the LED lamp driver board A to be inserted and for the electrical connection portion A1 on the electrical connection end of the driver board A to be in close contact with the first electrical connection portion 210 to achieve electrical connection. The second electrical connection portion 220 extends out of the insulating base 1 and is disposed outside the insulating base 1 for being in close contact with the electrical connection portion B1 on the electrical connection end of the light source board B to achieve electrical connection. A connector 3 is disposed on the insulating base 1 for stably mounting the electrical connector body on the light source board B.

[0015] In this specific embodiment, a positioning seat 12 for positioning and installing the conductive metal sheet 2 is provided inside the insulating base 1. A connecting slot 11 is provided on the upper part of the positioning seat 12, and a positioning groove 121 with a front and top opening is provided on the positioning seat 12. The main body of the conductive metal sheet 2 is fixed in the corresponding positioning groove 121. A first electrical connection part 210 extends upward from the top opening of the positioning groove 121 and is disposed in the connecting slot 11. A second electrical connection part 220 extends outward from the front opening of the positioning groove 121 and is disposed outside the insulating base 1. By providing a positioning seat 12 inside the insulating base 1 and providing a corresponding positioning groove 121 structure on the positioning seat 12, it can be ensured that the conductive metal sheet 2 can be installed accurately and stably.

[0016] Typically, there are at least two conductive metal sheets 2. Therefore, for the insulating base 1, a corresponding number of positioning slots 121 must be provided at intervals. In this specific embodiment, there are two conductive metal sheets 2, so there are also two corresponding positioning slots 121. The multiple positioning slots 121 are arranged at intervals to achieve electrical isolation between circuits, prevent short circuits, and improve safety.

[0017] In this specific embodiment, the bottom inner end face of the positioning groove 121 is a horizontal positioning surface 1211, the rear wall surface of the positioning groove 121 is a vertically arranged limiting surface 1212, the main body of the conductive metal sheet 2 includes a horizontally arranged positioning resting part 21, the positioning resting part 21 is positioned and mounted on the horizontal positioning surface 1211, the rear end of the positioning resting part 21 is bent upward vertically to form a first limiting part 22 that cooperates with the limiting surface 1212, and the first limiting part 22 abuts against the limiting surface 1212; The top end of the first limiting part 22 is bent upwards at an angle to form an angled bending part 23. The angled bending part 23 is inclined from back to front and upwards. The angled bending part 23 is disposed in the connecting slot 11. The end of the angled bending part 23 is bent downwards to form a first bending part 24. The connection between the angled bending part 23 and the first bending part 24 constitutes the first electrical connection part 210. The front end of the positioning and holding part 21 is bent downward vertically to form a second limiting part 25. The second limiting part 25 abuts against the front end surface of the insulating base 1, and the end of the second limiting part 25 is bent horizontally to form a second electrical connection part 220.

[0018] The above structural design utilizes the horizontal positioning surface 1211 and the vertical limiting surface 1212 to achieve precise positioning and fixation of the conductive metal sheet 2 in three-dimensional space; the first electrical connection part 210 formed by the oblique bending part 23 and the first bending part 24 can make elastic contact, ensuring close contact with the inserted electrical connection end and ensuring the reliability of the electrical connection; the second electrical connection part 220 extends directly outside the insulating base 1, facilitating the electrical connection at the other end.

[0019] In this specific embodiment, the left and right side ends of the positioning support portion 21 are respectively provided with barbed protrusions 211 with a horizontal cross-section of a triangle, and the width of the barbed protrusions 211 gradually decreases in the left and right directions. Through the design of the above-mentioned barbed structure, the conductive metal sheet 2 can be effectively prevented from loosening or falling out in the positioning groove 121, ensuring stable installation between the two and enhancing the fixing effect.

[0020] In this specific embodiment, the connector 3 includes an integrally formed welding part 31 and a mounting part 32. The bottom end face of the welding part 31 is a welding end face for welding onto the light source board B of the LED lamp. The front end face of the mounting part 32 extends towards the rear end face of the insulating base 1 and is provided with mounting pins 321. The rear end face of the insulating base 1 is correspondingly provided with mounting holes 10, and the mounting pins 321 are tightly inserted into the corresponding mounting holes 10. The connector 3 has clearly defined functional divisions, wherein the welding part 31 is responsible for welding and fixing to the light source board B, and the mounting part 32 is responsible for fixing to the insulating base 1. Moreover, the connector 3 is an integral part, with a simple structure, easy to manufacture, and easy to assemble.

[0021] In practical use, the specific connection positions of the electrical connection terminals on the light source board B and the driver board A in the lamp and the electrical connection body can be adjusted according to the specific situation. In other words, the electrical connection terminal on the light source board B can be inserted into the insertion gap 111, so that the electrical connection part B1 on the electrical connection terminal of the light source board B is in close contact with the first electrical connection part 210 to achieve electrical connection, and the electrical connection part on the electrical connection terminal of the driver board A is in close contact with the second conductive connection part to achieve electrical connection.

[0022] Example 2: The rest is the same as in Example 1, except that the number of positioning grooves 121 on the insulating base 1 is greater than the number of conductive metal sheets 2 used. This allows for flexible adjustment of the installation position of the conductive metal sheets 2, adapting to various different drive boards A or light source boards B. For example, in this specific embodiment, there are 2 conductive metal sheets 2 and 3 positioning grooves 121.

[0023] Example 3: The other parts are the same as in Example 1 or 2, except that the left and right sides of the positioning groove 121 are respectively recessed with guide grooves 1210 with front openings, and the left and right sides of the first limiting part 22 are respectively protruding with matching guide blocks 221, which are disposed in the corresponding guide grooves 1210. The guide grooves 1210 and guide blocks 221 cooperate to facilitate the precise positioning and installation of the conductive metal sheet 2. When the upper first conductive connection part is subjected to force, the guide blocks 221 are subjected to force to achieve the clamping installation of the conductive metal sheet 2 in the insulating base 1, ensuring the stability of the installation.

[0024] In this specific embodiment, the front opening of the guide groove 1210 is a guide opening 12101, and the width of the guide opening 12101 gradually decreases from front to back in the vertical direction. The tapering design of the guide opening 12101 facilitates the introduction of the guide block 221, making the installation smoother and less strenuous.
