Description

Technical Field

[0001] The present invention relates to the technical field of electric connectors, in particular to an electric connector for lighting lamps. Background Art

[0002] An electrical connector is an electromechanical component used to connect wires, cables, and control panels. It connects and disconnects circuits by plugging and unplugging. It is divided into free-end electrical connectors and fixed electrical connectors, also known as connectors or sockets. Electrical connectors play a vital role in electronic equipment, providing reliable electrical connections and facilitating the connection and disconnection of circuits. When lighting strips are extended in series, an electrical connector is often used at the butt joint to connect the wires.

[0003] When connecting the wires of a lighting lamp to a conventional electrical connector, the housing of the electrical connector is usually disassembled first, the insulation layers of the ends of the two wires are removed to expose the copper wires, and the copper wires are then connected through the wiring terminals, which are then inserted into the housing of the electrical connector. The housings are threadedly connected, and since the housing is small, it is not convenient to insert the wiring terminals into the housing, and the wires are easily bent, causing the joints to become loose, resulting in poor flexibility.

[0004] When the exposed copper wire at the end of the wire is connected to the terminal, screws are usually used to tighten the copper wire against the inner wall of the terminal. When fixing and removing the wire, the screws need to be repeatedly tightened and removed, which is cumbersome and has low installation efficiency.

[0005] Before two wires are connected through the terminal, their ends must pass through the two outer shells respectively and fit tightly with the sealing strips on the outer shells. After the two wires are connected, the two outer shells are threaded together, and the rotation of the outer shells can easily cause the wire connector to shift, causing the wire to fall off the terminal, resulting in poor stability.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1-Figure 7 and Fig.10As shown, an electrical connector for a lighting lamp described in the present invention comprises two partitions 1, a docking structure 2 fixed on the partition 1, a mounting structure 3 connected to the docking structure 2, a fixing structure 4 arranged on the docking structure 2, a driving structure 5 connected to the docking structure 2, and a sealing structure 6 installed on the driving structure 5, wherein the docking structure 2 comprises a female plug 201 and a male plug 202 engaged with the end of the female plug 201, one of the partitions 1 is fixedly connected with the female plug 201, and the other of the partitions 1 is fixedly connected with the male plug 202, and three wiring ports 203 are provided inside the female plug 201 and the male plug 202, and three wiring ports 203 are provided inside the partition 1, and one end of the female plug 201 close to the male plug 202 is fixedly connected with three plug posts 204, and the male plug One end of 202 close to the female plug 201 is fixedly connected with three sockets 205, the plug post 204 is engaged with the socket 205, the female plug 201 is matched with a mounting structure 3, the two partitions 1 are symmetrically arranged, and the ends of the female plug 201 and the male plug 202 are both provided with threads; when the female plug 201 and the male plug 202 are fixedly connected with copper wires, since the adjacent ends of the female plug 201 and the male plug 202 are respectively fixedly connected with the plug post 204 and the socket 205, and the interiors of the female plug 201 and the male plug 202 are both conductive, then at this time, only the plug post 204 needs to be connected with the socket 205 to complete the connection of the two wires, and only the end of the female plug 201 needs to be inserted into the male plug 202. At this time, the three plug posts 204 are inserted into the three sockets 205 in turn, and the conductive connection between the female plug 201 and the male plug 202 is completed.

[0037] Specifically, Figure 1-Figure 6As shown, the mounting structure 3 includes a swivel 301 and three fixed blocks 302 fixed on the outer wall of the swivel 301, the swivel 301 is rotatably connected to the outer wall of the female plug 201, and three fixed seats 304 are fixedly connected to the outer wall of the male plug 202, the ends of the fixed blocks 302 and the inner walls of the fixed seats 304 are in conflict with each other, a limiting groove 303 is provided on the fixed block 302, a limiting plate 305 is slidably connected to the fixed seat 304, and the limiting plate 305 is engaged with the limiting groove 303, a first sealing strip 306 is in conflict between the female plug 201 and the male plug 202, a slope is provided on the side of the fixed seat 304 that contacts the fixed block 302, the fixed block 302 slides with the slope, and the fixed block 302 is in a "U" shape; at this time, the fixed block 302 is in conflict with the fixed The seat 304 is then rotated, and the swivel 301 on the female plug 201 is then driven by the swivel 301 to drive the three fixing blocks 302 to rotate. Since the fixing blocks 302 slide with the inclined surfaces on the fixing seat 304, the three fixing blocks 302 are driven to slide along the inclined surfaces when the swivel 301 is rotated until they slide to the top of the inclined surfaces. Then, a screwdriver is used to press downward on the limit plate 305 on the fixing seat 304 so that the limit plate 305 is engaged with the limit groove 303 on the fixing block 302, thereby preventing the swivel 301 from rotating under the action of external force, and then completing the docking of the female plug 201 and the male plug 202, which has strong firmness, and there is a first sealing strip 306 between the female plug 201 and the male plug 202 to ensure the sealing. When the docking of the female plug 201 and the male plug 202 is completed, the connection of the two wires is completed, which is easy to operate and has good sealing.

[0038] Specifically, Figure 1-Figure 5 and Figure 7As shown, the fixed structure 4 includes a rotating shaft 401 and a driving strip 402 rotatably connected to the rotating shaft 401, the inside of the female plug 201 and the male plug 202 are fixedly connected with three rotating shafts 401, the inside of the female plug 201 and the male plug 202 are slidably connected with three driving rods 403, the driving strip 402 abuts against the driving rod 403, and the driving rod 403 and the female plug 201 and the male plug 202 are fixedly connected with a first spring 404, the bottom end of the driving rod 403 is fixedly connected with a fixing strip 406, the inside of the female plug 201 and the male plug 202 are fixedly connected with three second sealing strips 405, the driving rod 403 penetrates the second sealing strip 405, the cross section of the driving rod 403 is a "T"-shaped structure, and the cross section of the driving strip 402 is an "L"-shaped structure; at the same time, when the driving ring 501 is respectively connected to the female plug 201 and the male plug When the plug 202 is connected, since the driving ring 501 is threadedly connected to the outer walls of the female plug 201 and the male plug 202, during the process of tightening the driving ring 501, the front end of the driving ring 501 first contacts the driving strip 402, driving the driving strip 402 to rotate around the rotating shaft 401. When the driving ring 501 is continuously tightened, the end of the driving strip 402 is driven to squeeze the driving rod 403, driving the driving rod 403 to slide along the inner walls of the female plug 201 and the male plug 202 toward the inside of the wiring port 203 and compressing the first spring 404. At this time, the driving rod 403 drives the fixing strip 406 at the bottom to press the copper wire in the wiring port 203, thereby quickly fixing the copper wire on the plug column 204 and the socket 205, with high operation efficiency. A second sealing strip 405 is provided between the driving rod 403 and the inner walls of the female plug 201 and the male plug 202, thereby ensuring the sealing of the plug column 204 and the socket 205.

[0039] Specifically, Figure 1-Figure 10As shown, the driving structure 5 includes a driving ring 501 and a connecting cover 502 threadedly connected to the end of the driving ring 501, the ends of the female plug 201 and the male plug 202 are both threadedly connected to the driving ring 501, the end of the driving ring 501 is rotatably connected to a sealing cover 503, a plurality of balls 504 are rollingly connected between the sealing cover 503 and the connecting cover 502, and a slide groove 505 is provided on the inner wall of the driving ring 501 and the sealing cover 503, the outer wall of the partition 1 is fixedly connected to a limiting rod 506, the limiting rod 506 is slidably connected to the inner wall of the slide groove 505, and the end of the female plug 201 close to the partition 1 is fixedly connected to a third sealing strip 507; when the two wires are respectively inserted into the two sealing covers 503, the two driving rings 501 are respectively aligned with the female plug 201 and the male plug 202, and then the three copper wires at the ends of the wires are inserted into the wiring port 203 in sequence, and at the same time, the two driving rings 50 1 is threadedly connected with the female plug 201 and the male plug 202 in sequence. At this time, the driving ring 501 is twisted. Since the end of the driving ring 501 is rotatably connected with the sealing cover 503 through the ball 504, it is prevented from driving the sealing cover 503 to rotate when the driving ring 501 is tightened, thereby effectively preventing the sealing cover 503 from driving the wire to rotate and causing the wire to shift and fall off. The flexibility is strong. At the same time, the end of the driving ring 501 is threadedly connected with the connecting cover 502, which is convenient for removing the sealing cover 503. The operation is simple. In the process of installing the sealing cover 503, the driving ring 501 is first inserted inward along the outer wall of the female plug 201 by one end. At this time, the limiting rod 506 fixed at the end of the female plug 201 and the male plug 202 slides along the slide groove 505 to the inside of the sealing cover 503, so that the sealing cover 503 is limited in the process of rotating the driving ring 501, further preventing the driving ring 501 from driving the sealing cover 503 to rotate, and the flexibility is strong.

[0040] Specifically, Figure 1 , Figure 4 , Figure 6 , Figure 8 and Fig. 9As shown, the sealing structure 6 includes a connecting block 601 and a rubber plate 602 fixedly connected to the connecting block 601, the connecting block 601 is fixedly connected inside the sealing cover 503, the rubber plate 602 abuts against the sealing cover 503, four connecting rods 604 are slidably connected inside the connecting block 601, the ends of the four connecting rods 604 are fixedly connected to rubber blocks 603, the rubber blocks 603 and the inner wall of the connecting block 601 abut against each other, the rubber block 603 is slidably connected to the rubber plate 602, a second spring 605 is fixedly connected between the rubber block 603 and the inner wall of the connecting block 601, the cross section of the connecting block 601 is a circular structure, and the cross sections of the four rubber blocks 603 are all arc structures; in the process of pulling the copper wire into the driving ring 501, the insulating layer on the wire slides between the four rubber blocks 603, and the internal cable will be bent during the stripping process, causing the cable to The overall outer diameter becomes larger, and in the process of pulling the copper wire inward, the wire resists the four rubber blocks 603 and slides toward the inner side of the connecting block 601. The rubber block 603 drives the connecting rod 604 to slide along the inner wall of the connecting block 601, and compresses the second spring 605 at the same time. Since the second spring 605 is always in a compressed state at this time, and the elasticity of the second spring 605 is relatively large, the four rubber blocks 603 are driven to press against the wires under the resetting action of the second spring 605. When the stripping part is completely out of contact with the rubber block 603, the second spring 605 stretches and resets, so that the second spring 605 drives the four rubber blocks 603 to completely resist the wires. The four rubber blocks 603 form a circle, which ensures the sealing, thereby achieving a good sealing effect. A rubber plate 602 is fixed between the connecting block 601 and the sealing cover 503, and a third sealing strip 507 is provided between the female plug 201 and the sealing cover 503, thereby further ensuring the sealing of the internal cavity of the sealing cover 503.

[0041] When the present invention is in use, the insulating layers at the ends of the two electric wires are removed until the three copper wires inside the electric wires are exposed (each electric wire has three copper wires with insulating layers inside, and the three copper wires with insulating layers are respectively a live wire, a neutral wire and a ground wire), and then the two electric wires are respectively inserted into the interior of the two sealing covers 503, and the three copper wires are passed through the reserved holes in the middle of the sealing covers 503, so that the three copper wires pass into the internal cavity of the driving ring 501, and then the three copper wires are pulled from one end of the driving ring 501 so that the electric wires completely pass through the sealing covers 503 and the driving ring 501. In the process of pulling the copper wires into the driving ring 501, the insulating layer on the electric wires slides with the four rubber blocks 603. Since the internal cable will bend during the wire stripping process, the overall outer diameter of the cable will increase. In the process of pulling the copper wires inward, the electric wires will resist the four rubber blocks 603 to the connecting wires. The inner side of the connecting block 601 slides, and the rubber block 603 drives the connecting rod 604 to slide along the inner wall of the connecting block 601, and compresses the second spring 605 at the same time. Since the second spring 605 is always in a compressed state at this time, and the elasticity of the second spring 605 is relatively large, the four rubber blocks 603 are driven to press against the wires under the resetting action of the second spring 605. When the stripping part is completely out of contact with the rubber block 603, the second spring 605 stretches and resets, so that the second spring 605 drives the four rubber blocks 603 to completely contact the wires. The four rubber blocks 603 form a circle, which ensures the sealing, thereby achieving a good sealing effect. A rubber plate 602 is fixed between the connecting block 601 and the sealing cover 503, and a third sealing strip 507 is provided between the female plug 201 and the sealing cover 503, thereby further ensuring the sealing of the internal cavity of the sealing cover 503.

[0042] After the two wires are respectively inserted into the two sealing covers 503, the two driving rings 501 are respectively aligned with the female plug 201 and the male plug 202, and then the three copper wires at the ends of the wires are inserted into the wiring port 203 in turn. At the same time, the two driving rings 501 are threadedly connected with the female plug 201 and the male plug 202 in turn. At this time, the driving ring 501 is twisted. Since the end of the driving ring 501 is rotatably connected to the sealing cover 503 through the ball 504, it is prevented from rotating the sealing cover 503 when the driving ring 501 is tightened, thereby effectively preventing the sealing cover 503 from rotating the wires and causing the wires to move. The end of the driving ring 501 is threadedly connected with a connecting cover 502, which is convenient for disassembling the sealing cover 503. The operation is simple. During the installation of the sealing cover 503, the driving ring 501 is first inserted inward along the outer wall of the female plug 201 by one end. At this time, the limiting rod 506 fixed at the ends of the female plug 201 and the male plug 202 slides along the slide groove 505 to the inside of the sealing cover 503, so that the sealing cover 503 is limited in the process of rotating the driving ring 501, further preventing the driving ring 501 from driving the sealing cover 503 to rotate, and the flexibility is strong.

[0043] At the same time, when the driving ring 501 is connected to the female plug 201 and the male plug 202 respectively, since the driving ring 501 is threadedly connected to the outer walls of the female plug 201 and the male plug 202, during the process of tightening the driving ring 501, the front end of the driving ring 501 first contacts the driving bar 402, driving the driving bar 402 to rotate around the rotating shaft 401. When the driving ring 501 is continuously tightened, the end of the driving bar 402 is driven to squeeze the driving rod 403, driving the driving rod 403 to move along the female plug 201 and the male plug 202. The inner walls of the plug 201 and the male plug 202 slide toward the inside of the wiring port 203 and compress the first spring 404. At this time, the driving rod 403 drives the fixing strip 406 at the bottom to press the copper wire in the wiring port 203, thereby quickly fixing the copper wire on the plug column 204 and the socket 205, with high operation efficiency. A second sealing strip 405 is provided between the driving rod 403 and the inner walls of the female plug 201 and the male plug 202, thereby ensuring the sealing of the plug column 204 and the socket 205.

[0044] When the female plug 201 and the male plug 202 are both fixedly connected with copper wires, since the adjacent ends of the female plug 201 and the male plug 202 are respectively fixedly connected with the plug post 204 and the socket 205, and the interiors of the female plug 201 and the male plug 202 are both conductive, it is only necessary to connect the plug post 204 and the socket 205 to complete the connection of the two wires, and it is only necessary to insert the end of the female plug 201 into the male plug 202. At this time, the three plug posts 204 are inserted into the three sockets 205 in turn, and the conductive connection between the female plug 201 and the male plug 202 is completed. At this time, the fixed block 302 is in contact with the fixed seat 304 on the male plug 202, and then the swivel 301 on the female plug 201 is rotated, and the swivel 301 drives the three fixed blocks 302 to rotate. The fixing block 302 slides with the inclined surface on the fixing seat 304, and then the three fixing blocks 302 are driven to slide along the inclined surface when the swivel 301 is rotated until they slide to the top of the inclined surface, and then a screwdriver is used to press down the limit plate 305 on the fixing seat 304, so that the limit plate 305 is engaged with the limit groove 303 on the fixing block 302, thereby preventing the swivel 301 from rotating under the action of external force, and then completing the docking of the female plug 201 and the male plug 202, with strong firmness, and a first sealing strip 306 is in contact between the female plug 201 and the male plug 202 to ensure the sealing. When the docking of the female plug 201 and the male plug 202 is completed, the connection of the two wires is completed, which is easy to operate and has good sealing.
