Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring-loaded electrical connector technology, specifically a spring-loaded electrical connector. Background Technology
[0002] Electrical connectors are used to connect different electronic components or modules, enabling the transmission of electronic signals between them. Some electrical connectors are mounted on circuit boards, forming an electrical connection with the board. Existing electrical connectors use either through-hole or surface-mount terminals to connect to the circuit board, or post-shaped solder pads to connect to the circuit board's solder pads.
[0003] Existing spring-loaded electrical connectors require an auxiliary tool to pry the spring, aligning the cable insertion point of the spring with the connector's overall socket. After the cable is inserted, the auxiliary tool is removed, and the cable moves with the spring under its rebound force to adhere to the conductive plate, thus completing the installation of the cable and connector. The entire connector and cable are fixed solely by the elastic force of the spring after installation. Under external pulling force, the cable is highly likely to detach, affecting connection stability. Furthermore, the point of force application is directly at the location where the spring pulls the cable to adhere to the conductive plate. If the friction of the spring is too high, the pulling force may cause the cable to break, and it will also wear down the spring, affecting the normal and stable use of the cable and failing to protect the connector. While using an integrated pressing plate to directly push the spring eliminates the need for an auxiliary tool, making installation easier, the pressing plate is inevitably located on the outside of the connector, within easy reach. The exposed pressing mechanism, without effective protection after connection, may cause secondary accidental contact, leading to secondary movement of the spring and cable loosening, thus affecting the stability of the cable connection.
[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a spring-type electrical connector. Utility Model Content
[0005] The purpose of this invention is to provide a spring-loaded electrical connector to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring-loaded electrical connector, comprising a connector body, a fixing ring fixedly installed on the lower side of the outer surface of the connector body, a threaded groove formed on the upper surface of the fixing ring, a cover sleeve provided on the upper side of the fixing ring, a threaded head one fixedly installed at the lower end of the cover sleeve, a threaded head two fixedly installed at the upper end of the cover sleeve, a rubber ring fixedly connected to the upper end of the threaded head two, and a top cover threadedly connected to the surface of the threaded head two.
[0007] Preferably, the covering sleeve is helically connected to the fixing ring via a threaded groove using a threaded head, the rubber ring is conical, and the upper side of the top cover is shaped like a round ball.
[0008] Preferably, cavities are provided on both the left and right sides of the upper surface of the outer surface of the connector body. The cavity is L-shaped, and the upper end of the vertical cavity is connected to the top of the connector body.
[0009] Preferably, elastic paddles are fixedly installed on the upper side of the inner surface of the cavity at the left and right openings of the connector body, and push blocks are fixedly installed on the opposite side of the surface of the elastic paddles.
[0010] Preferably, a transmission missile piece is fixedly installed on the bottom of the inner surface of the cavity, and a through cavity is formed on the upper side of the surface of the transmission missile piece.
[0011] Preferably, the transmission missile piece is arranged in a loop shape, and the upper end of the vertical piece itself passes through the cavity.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of a fixing ring, threaded groove, covering sleeve, threaded head one, threaded head two, rubber ring and top cover, the covering sleeve covers and protects the entire connector body, avoiding accidental manual contact of the elastic tab, which could lead to cable connection loosening. It also increases the squeezing friction of the cable rear section, thereby ensuring stable installation between the cable and the connector body, making the cable less prone to loosening and the connection more secure.
[0014] 2. This utility model, through the arrangement of an elastic lever, a push block, a transmission slide, and a through cavity, allows manual inward squeezing of the elastic lever. The elastic lever, using the push block, propels the transmission slide towards the top opening of the cavity. At this time, the through cavity moves to align with the top opening of the cavity. After the cable is inserted into the through cavity through the cavity, releasing the elastic lever causes it to automatically reset and lose its thrust on the transmission slide. The transmission slide also automatically resets using its elasticity, thereby pulling the cable to fit against the vertical body of the transmission slide, thus completing the cable connection. No external auxiliary tools are required; the transmission slide can be manipulated to assemble the cable, making the device connection simpler and the operation more convenient and faster.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1-3 As shown, a spring-loaded electrical connector includes a connector body 1. A retaining ring 2 is fixedly installed on the lower side of the outer surface of the connector body 1. A threaded groove 3 is formed on the upper surface of the retaining ring 2. A cover sleeve 4 is provided on the upper side of the retaining ring 2. A threaded head 5 is fixedly installed at the lower end of the cover sleeve 4. A threaded head 6 is fixedly installed at the upper end of the cover sleeve 4. A rubber ring 7 is fixedly connected to the upper end of the threaded head 6. A top cover 8 is threadedly connected to the surface of the threaded head 6. The cover sleeve 4 is spirally connected to the retaining ring 2 through the threaded groove 3 using the threaded head 5. The rubber ring 7 is set in a conical shape, and the upper side of the top cover 8 is set in a round ball shape.
[0021] By adopting the above technical solution, the top cover 8 and the covering sleeve 4 can be preferentially fitted onto the surface of the connected cable;
[0022] After the cable is connected to the connector body 1, the threaded head 5 at the bottom of the top cover 8 is inserted into the threaded groove 3 and screwed in to fix the cover 4 and the retaining ring 2. At this time, the cover 4 covers the entire connector body 1 and protects the entire connector body 1 to prevent accidental manual contact with the elastic lever 10, which could cause the cable connection to become loose.
[0023] Tighten the top cover 8 and the threaded head 6 to fix the top cover 8 to the upper end of the cover sleeve 4. As the top cover 8 is gradually tightened, it will press down on the rubber ring 7. Since the rubber ring 7 is a cone shape that is narrow at the top and wide at the bottom, when it is pressed down, the rubber ring 7 will be concave inward, so that the rubber ring 7 is tightly pressed on the surface of the cable, and the cable is fully fixed.
[0024] Furthermore, cavities 9 are provided on both the left and right sides of the upper surface of the outer surface of the connector body 1. The shape of the cavities 9 is set as "L" and the upper end of the vertical cavity of the cavity 9 is connected to the top of the connector body 1.
[0025] By adopting the above technical solution, the cable can be inserted into the connector body 1 for connection by utilizing the upper end connection position of cavity 9.
[0026] Furthermore, elastic levers 10 are fixedly installed on the upper side of the inner surface of the cavity 9 at the left and right openings of the connector body 1, and push blocks 11 are fixedly installed on the opposite side of the surface of the elastic levers 10.
[0027] By adopting the above technical solution, the elastic lever 10 can be manually pushed to make the push block 11 move directly into the cavity 9.
[0028] Furthermore, a transmission missile piece 12 is fixedly installed on the bottom of the inner surface of the cavity 9, and a through cavity 13 is opened on the upper side of the surface of the transmission missile piece 12; the transmission missile piece 12 is arranged in a loop shape, and the upper end of the vertical piece of the transmission missile piece 12 passes through the through cavity 13.
[0029] By adopting the above technical solution, when the propulsion block 11 moves into the cavity 9, it will push the missile piece 12 to move towards the top opening of the cavity 9;
[0030] The through cavity 13 will move along with the transmission missile piece 12 and be aligned with the top opening of the cavity 9, so that after the cable is inserted into the cavity 9, it can be accurately inserted into the through cavity 13.
[0031] Working principle: When using this spring-loaded electrical connector, firstly, the top cover 8 and the sheath 4 are fitted onto the surface of the cable to be connected. Then, the elastic tab 10 is manually squeezed inward. The elastic tab 10 will use the pusher block 11 to push the transmission tab 12 towards the top opening of the cavity 9. At this time, the through cavity 13 will move to face the top opening of the cavity 9. After the cable is inserted into the through cavity 13 through the cavity 9, the elastic tab 10 is released. The elastic tab 10 automatically resets and loses its pushing force on the transmission tab 12. The transmission tab 12 also automatically resets using its elasticity, thereby pulling the cable to fit against the vertical body of the transmission tab 12, thus completing the connection of the cable. The cable is then connected to the connector body 1. After that, slide the top cover 8 and insert the threaded head 5 at the bottom of the top cover 8 into the threaded groove 3 and screw it in to fix the cover 4 and the retaining ring 2. At this time, the cover 4 covers the entire connector body 1 and protects the entire connector body 1. This can prevent accidental manual contact with the elastic tab 10, which could cause the cable connection to become loose. Then slide the top cover 8 again and screw the top cover 8 and the threaded head 6 in place to fix the top cover 8 and the upper end of the cover 4. As the top cover 8 is gradually screwed in, it will press down on the rubber ring 7, making the rubber ring 7 tightly squeezed against the surface of the cable and fully fixing the cable. This completes the stable and firm connection between the cable and the connector body 1. This is the working principle of the spring-loaded electrical connector.
