Description

TECHNICAL FIELD

[0001] The utility model relates to connecting terminal technical field especially relates to self -locking high -frequency connecting terminal. BACKGROUND

[0002] With the rapid development of electronic industry, especially the high -speed growth of communication and information industry, the demand of electric connector is higher and higher, these fields are extremely strict to the performance requirement of connector, especially in high -frequency transmission and signal stability, self -locking high -frequency connecting terminal is widely used in household appliances, industrial automation, automobile electronics, communication equipment and multiple fields.

[0003] In the prior art, the traditional high -frequency connecting terminal is easy to fall off when connecting, in industrial automation and automobile electronics and the like application, the vibration produced when the equipment runs is a common phenomenon, these vibrations can cause the traditional high -frequency connecting terminal to gradually loosen, and eventually can completely fall off, this loosening not only affects the stable transmission of electrical signal, but also can cause the circuit interruption, thereby affecting the normal operation of the equipment, with the lapse of time, the material used in the traditional high -frequency connecting terminal can appear aging phenomenon, such as plastic piece brittle, metal piece rust and the like, these problems can cause the mechanical strength of the connecting terminal to decrease, and further cause unstable connection and even fall off, especially in harsh working environment, such as damp, more places of corrosive gas, the speed of material aging will be faster, thereby causing its performance to decrease and even causing failure and safety hazard. UTILITY MODEL CONTENTS

[0004] The utility model discloses a self -locking high -frequency connecting terminal to solve the shortcomings in the prior art.

[0005] In order to realize the above -mentioned purpose, the utility model discloses a self -locking high -frequency connecting terminal that adopts the following technical scheme: the self -locking high -frequency connecting terminal includes the connecting base, the connecting base upper end detachably connected with the interface base, the interface base interior fixed with the connecting rubber covered wire, the interface base interior slidingly connected with the sliding mortgage piece, the sliding mortgage piece upper end fixed with the pressing ring, the connecting base interior fixed with the connecting inner tube, the connecting base interior slidingly connected with the sliding inner tube, the sliding inner tube bottom fixed with the support spring, the support spring bottom and the connecting base bottom fixed connection, the connecting inner tube interior slidingly connected with the self -locking ball, the interface base bottom fixed with the connecting lock pin, the connecting lock pin surface is equipped with the arc groove.

[0006] Preferably, a fixing bottom ring is fixed to the inner wall of the connecting inner tube, a connecting contact rod is fixed inside the fixing bottom ring, a buffer spring is fixed to the bottom of the fixing bottom ring, and an interface connector is fixed to the bottom of the buffer spring. The surface of the interface connector is slidably connected to the inner wall of the connecting inner tube, and the surface of the connecting contact rod is slidably connected to the inside of the interface connector. In the prior art, traditional high-frequency connecting terminals usually do not have a dedicated buffer design. This means that when external force is applied to the connecting wire, all stress will be directly transmitted to the connection point. In this case, even a slight pull may cause the connecting wire to break or have poor contact. For example, in household appliances, if a user accidentally trips over the power cord, the wire inside the connector may be pulled off. To address this problem, this utility model uses a buffer device. When a worker walks and accidentally pulls up the connecting wire of the connecting terminal, the connecting wire drives the buffer spring to buffer the movement, causing the interface connector to slide along the connecting contact rod. After the worker releases their foot, the buffer spring resets the interface connector, and the energy is dissipated by its internal energy, thereby avoiding the risk of the interface connector falling off.

[0007] Preferably, the surface of the connecting base is covered with a rubber sleeve. By increasing friction, the anti-slip texture helps reduce operational errors or accidents caused by slipping, thereby improving overall operational safety. This is especially beneficial in humid, oily, or slippery working environments.

[0008] Preferably, the bottom of the connecting locking pin has an arc-shaped platform. The design of the arc-shaped platform makes it easier to align the connecting locking pin with the holes or slots on the parts to be connected during installation. Since the arc-shaped platform has a certain guiding function, it can reduce the difficulty of alignment during installation, thereby speeding up the installation process.

[0009] Preferably, the support spring is a double-strand spring, which consists of two spring wires. Compared to a single-strand spring, it has stronger elasticity and load-bearing capacity. This design allows the double-strand spring to remain stable under greater pressure or tension, and is less prone to deformation or breakage.

[0010] Preferably, a sliding key is fixed to the circumference of the interface connector, and a sliding groove is formed inside the connecting inner tube. The cooperation between the key and the sliding groove provides additional axial and radial constraints, making the position of the interface connector in the connecting inner tube more stable. This design can effectively prevent the interface connector from loosening or falling off due to vibration or external force during use.

[0011] Preferably, the inner wall of the bottom of the connecting inner tube is fixed with sealant. This design prevents dust and foreign objects from entering, improves connection stability, and enhances sealing performance.

[0012] Beneficial effects

[0013] 1、In the prior art, the traditional high-frequency connection terminal is prone to falling off during connection. In industrial automation and automotive electronics applications, vibration generated during equipment operation is a common phenomenon. These vibrations can cause the traditional high-frequency connection terminal to gradually loosen, and eventually may completely fall off. This loosening not only affects the stable transmission of electrical signals, but also can cause circuit interruption, thereby affecting the normal operation of the equipment. Over time, the materials used in the traditional high-frequency connection terminal may age, such as plastic parts becoming brittle and metal parts rusting. These problems can cause the mechanical strength of the connection terminal to decrease, thereby causing unstable connection or even falling off, especially in harsh working environments such as humid and corrosive gas-rich places, where the material aging rate will be faster, thereby causing performance degradation or even causing faults and safety hazards. To address these problems, the utility model has a self-locking structure. When the staff needs to install the connection terminal, the pressing ring is pressed downward to press the sliding inner tube, which causes the sliding inner tube to be lower than the self-locking ball, thereby causing the self-locking ball to expand outward and separate from the surface arc groove of the connecting lock pin, thereby causing the connecting lock pin to separate from the connecting inner tube. When the staff installs the connection terminal, the connecting lock pin is inserted along the connecting base, and the staff presses the pressing ring. After pushing the interface base, the connecting lock pin is inserted into the connecting inner tube, and the pressing ring is released. The sliding inner tube is reset with the help of the supporting spring, and the sliding inner tube inner wall extrudes the self-locking ball, which is self-locked and fixed, thereby completing the installation and improving the overall stability of the connection terminal.

[0014] 2、In the prior art, the traditional high-frequency connection terminal usually does not have a special buffer design, which means that when external force acts on the connecting line, all stress is directly transmitted to the connection point. In this case, even slight pulling can cause the connecting line to break or have poor contact. For example, in household appliances, if the user accidentally trips over the power cord, the internal wire of the connector may be pulled off. To address these problems, the utility model has a buffer device. When the staff walks with the connecting line of the connection terminal, the connecting line drives the buffer spring to buffer, causing the interface connecting line to slide along the connection contact rod. After the staff releases their foot, the buffer spring resets the interface connecting line, and the energy between them is consumed by the internal energy, thereby avoiding the risk of interface connecting line falling off.
