Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically a male-female coupling stable connector. Background Technology

[0002] Connectors are widely used in communication fields such as Ethernet and fieldbus. They are also used in small motors and limit switches on automated production lines, some small sensor devices, industrial automation, machinery manufacturing, and instrumentation. A connector is an electromechanical component used to connect electronic devices, circuits, or components. Its main function is to transmit electrical signals, optical signals, or mechanical connections. It acts like a bridge in an electronic system, providing a stable connection for the circuit while facilitating equipment assembly and maintenance. Circuit conduction is achieved through the insertion and removal of male and female contacts, maintaining signal integrity. For example, electrical connectors require low contact resistance, and high-speed data connectors require continuous impedance. The male and female contacts of the connector achieve circuit conduction through mechanical mating. Its core working principle lies in the physical design of elastic contact and rigid fit. They are often protruding needle-like or plate-like structures, typically designed as cylindrical pins, square pins, or flat plates, and are mostly made of brass to ensure conductivity. A servo motor electrical connector, as disclosed in Chinese Patent No. CN221783515U, includes an insulating body and a plurality of terminals inserted into the insulating body along the insertion direction. The insulating body has a first surface facing the insertion direction with a insertion groove. The plurality of terminals have a recessed section embedded in the insulating body, an insertion section inserted into the insertion groove, and a connecting section exposed on a second surface of the insulating body away from the first surface. The connecting section is electrically connected to a wire. A wire guard frame is provided on the second surface of the insulating body, enclosing the connection points between the plurality of terminals and the corresponding wires. Adhesive is injected into the wire guard frame. This invention provides a wire guard frame on the insulating body of the electrical connector to protect the connection points between the wires and terminals. Simultaneously, the wire guard frame limits the accumulation of adhesive during the adhesive injection process, ensuring uniform accumulation and improving the stability of the wires while also guaranteeing the aesthetics of the finished product.

[0003] Existing connectors require male and female insertion for fixation, which can result in tiny gaps at the insertion points, leading to poor sealing after connection. Therefore, a male-female coupling stable connector is proposed to address this issue. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Please see Figures 1-4This utility model provides a male-female coupling stable connector, including a female connector body 2; one side of the female connector body 2 abuts against a male connector body 1, one end of the female connector body 2 has a sealing groove 11, the inner surface wall of the male connector body 1 has an inner sliding groove 19, a second sliding rod 21 is fixedly connected to the inner surface wall of the male connector body 1, a first sliding rod 20 is slidably connected to the outer surface wall of the second sliding rod 21, one end of the first sliding rod 20 is fixedly connected to a rubber sealing plate 17, the rubber sealing plate 17 is slidably connected to the inner surface wall of the male connector body 1, and the rubber sealing plate 17 is connected to the male connector body 1 through the male connector body 1. A spring 22 is fixedly connected to the body 1. During operation, when the male connector body 1 and the female connector body 2 are closed, the rubber sealing plate 17 is inserted into the inner wall of the sealing groove 11. At the same time, the rubber sealing plate 17 is pushed by the female fixing frame 4 to slide and limit its movement on the inner wall of the male connector body 1. This causes the first slide rod 20 to slide and limit its movement on the outer wall of the second slide rod 21. Simultaneously, the spring 22 is compressed, which in turn increases the contact force between the rubber sealing plate 17 and the female fixing frame 4, thereby enabling the rubber sealing plate 17 to better play its role in auxiliary sealing.

[0020] Furthermore, such as Figure 1 and Figure 3 As shown, a wire guard frame 5 is fixedly connected to the outer wall of both the female connector body 2 and the male connector body 1. Wires 6 are electrically connected to the outer walls of both the female connector body 2 and the male connector body 1. A rotating base 18 is fixedly connected to the outer wall of the wire guard frame 5. During operation, the wire guard frame 5 assists in connecting the wires 6 to the connector.

[0021] Furthermore, such as Figure 1 As shown, a rotating support rod 7 is rotatably connected to the outer wall of the rotating base 18, and a limiting clamp 8 is rotatably connected to one end of the rotating support rod 7. During operation, the rotating support rod 7 can be limited to rotate inside the rotating base 18, and the limiting clamp 8 can also be limited on the outer wall of the wire 6 after rotation, thus using the limiting clamp 8 to perform the function of wire binding and fixing.

[0022] Furthermore, such as Figure 1 As shown, a fixing screw 9 is inserted into the inner wall of the limiting clamp 8, and hexagonal nuts 10 are threaded to both ends of the fixing screw 9. During operation, after the limiting clamp 8 is in position, the fixing screw 9 can be inserted into the inner wall of the limiting clamp 8, and then the hexagonal nuts 10 can be threaded to both ends of the fixing screw 9, thereby assisting in fixing the limiting clamp 8.

[0023] Furthermore, such as Figure 1As shown, a female connector fixing frame 4 is fixedly connected to the outer wall of the female connector body 2, and a male connector fixing frame 3 is fixedly connected to the outer wall of the male connector body 1. During operation, the female connector fixing frame 4 and the male connector fixing frame 3 are designed to assist in the connection between the female connector body 2 and the male connector body 1.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, both the female head fixing frame 4 and the male head fixing frame 3 have preset holes 16. The female head fixing frame 4 is connected to the male head fixing frame 3 via a connecting screw 12. Both ends of the connecting screw 12 are threaded with internal thread knobs 13. During operation, the connecting screw 12 can be inserted into the inner surface of the female head fixing frame 4 and the male head fixing frame 3. Then, the internal thread knobs 13 can be screwed onto both ends of the connecting screw 12, causing the internal thread knobs 13 to move along the threads and abut against both sides of the female head fixing frame 4 and the male head fixing frame 3.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, a female connector body 2 is equipped with a female connector end 14 at one end, and a male connector body 1 is equipped with a male connector end 15 at one end. The female connector end 14 and the male connector end 15 are connected. During operation, the male connector end 15 can be inserted into the inner wall of the female connector end 14.

[0026] Working principle: During the closing process of the male connector body 1 and the female connector body 2, the rubber sealing plate 17 is inserted into the inner wall of the sealing groove 11. Simultaneously, the rubber sealing plate 17 is pushed by the female fixing frame 4 to slide within the inner wall of the male connector body 1, limiting its movement. This also causes the first slide rod 20 to slide within the outer wall of the second slide rod 21, compressing the spring 22. This, in turn, increases the contact force between the rubber sealing plate 17 and the female fixing frame 4, allowing the rubber sealing plate 17 to better assist in sealing. The wire guard frame 5 assists in the connection between the wire 6 and the connector. After the limiting clamp 8 limits the connection... The fixing screw 9 can be inserted into the inner wall of the limiting clamp 8, and then the hexagonal nut 10 is threaded onto both ends of the fixing screw 9, thereby assisting in fixing the limiting clamp 8. The design of the female head fixing frame 4 and the male head fixing frame 3 can assist in connecting the female head connector body 2 and the male head connector body 1. The connecting screw 12 can be inserted into the inner wall of the female head fixing frame 4 and the male head fixing frame 3. Then the internal thread knob 13 can be threaded onto both ends of the connecting screw 12, and then the internal thread knob 13 moves along the thread and abuts against both sides of the female head fixing frame 4 and the male head fixing frame 3. The male head insertion end 15 can be inserted into the inner wall of the female head insertion end 14.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
