[0028] EMBODIMENT

[0029] Please refer to Figures 1-4 The utility model provides a novel radio frequency connection assembly, including female terminal 1, male terminal 2, protective shell 3, protective sleeve 4, fusing device 5, clamping structure 6, elastic assembly 7, electricity-dissipating layer 8, anti-skid layer 9.

[0030] Further, the female terminal 1 is fixedly sleeved in the protective shell 3, the male terminal 2 is fixedly sleeved in the protective sleeve 4, the protective shell 3 and the protective sleeve 4 protect the butt joint of the two terminals, avoid the terminal to be easily destroyed, and the two terminals are connected with the radio frequency cable part, the female terminal 1 is butt jointed with the male terminal 2, and is used for information transmission.

[0031] Further, the protective shell 3 and the protective sleeve 4 are provided with a clamping structure 6 for quickly fixing or loosening the protective shell 3 and the protective sleeve 4, so that the female terminal 1 and the male terminal 2 are smoothly connected or separated.

[0032] Further, the protective sleeve 4 and the clamping structure 6 are further provided with a fuse device 5, the fuse part of the fuse device 5 is located at the clamping end of the clamping structure 6, and the sensing end of the fuse device 5 is close to the male terminal 2. When a short circuit occurs when the two terminals are connected, a high temperature is generated at the terminal, and the high temperature is sensed by the sensing end, so that the fuse part of the fuse device 5 is fused, thereby separating the female terminal 1 and the male terminal 2 in the connection, avoiding the fire of the connected circuit due to the short circuit, and making the fire spread along the circuit to the other end of the terminal connection, causing the fire to spread and causing more serious fire accidents.

[0033] Please refer to Figure 2 In this embodiment, the clamping structure 6 includes a clamping block 601 and a clamping groove 602.

[0034] The fuse device 5 includes a shell 501, a fuse block 502, and a heat conduction sheet 503.

[0035] Specifically, the shell 501 is threadedly connected to the protective sleeve 4 away from one end of the two-terminal connection, and the male terminal 2 in the protective sleeve 4 is inserted into the shell 501.

[0036] The shell 501 is fixedly provided with the fuse block 502 close to one end of the two-terminal connection, the fuse block 502 is inserted with the heat conduction sheet 503, and the other end of the heat conduction sheet 503 is close to the male terminal 2.

[0037] One end of the fuse block 502 is further fixedly connected with the clamping block 601, and the clamping groove 602 is throughly provided on one side wall of the protective shell 3, when the two terminals are connected, the clamping block 601 is clamped in the clamping groove 602, temporarily fixing the protective shell and the shell 501.

[0038] Preferably, the fuse block 502 is of an elastic glue structure, and the fuse block 502 has elasticity to enable the connected clamping block 601 to elastically swing, facilitating smoother clamping and separation with the clamping groove 602.

[0039] Under normal environmental conditions, the melting point temperature range of the insulating rubber on the outside of the cable is generally between 100 degrees and 200 degrees, at which time the insulating rubber will slowly soften and melt, and above 200 degrees, the insulating rubber will quickly melt. When a short circuit occurs, a high temperature of thousands of degrees Celsius is generated at the short circuit point in an instant, and the short circuit temperature is generally within 250 degrees near the short circuit point, and the duration is within 5 seconds.

[0040] Preferably, the fuse block 502 is also made of glue, so that it softens and melts when subjected to high temperature, and the heat-conducting sheet 503 inserted in the fuse block 502 is made of metal and can quickly conduct heat. Therefore, when a short circuit occurs at the terminal or a fire caused by a short circuit spreads to the terminal, the temperature near the terminal connection rapidly rises to the softening and melting temperature of the glue, at which time the heat-conducting sheet 503 near the terminal conducts the high temperature to the insertion part of the fuse block 502, so that the fuse block 502 begins to soften and melt. Finally, the molecular bonds in the glue structure cannot continue to connect, so that the insertion part of the fuse block 502 breaks first, thereby separating the shell 501 from the clamping block 601, and the terminal on the shell 501 is separated from the female terminal 1 in the protective shell, so that the cable circuit is separated, thereby avoiding the spread of a fire caused by a short circuit along the cable circuit to cause a larger safety accident.

[0041] Further, the elastic assembly 7 is arranged between the fuse device 5 and the protective shell 3, and the elastic displacement direction of the elastic assembly 7 is along the direction of the butt joint of the two terminals, so that the elastic assembly 7 helps the two mutually sleeved and butt-jointed terminals to quickly separate.

[0042] The elastic force of the elastic assembly 7 can apply an elastic pulling force to the fuse block 502 when the fuse block 502 softens and melts due to high temperature, so that the fuse block 502 can be pulled and broken after softening to a certain degree without melting, thereby avoiding that the fuse block 502 melts for too long.

[0043] Please refer to Figure 3 In the embodiment, the elastic assembly includes a sliding groove 701, a spring 702, and a sliding column 703.

[0044] Specifically, the sliding groove 701 is arranged on the butt joint end surface of the protective shell 3, the sliding column 703 is slidably arranged in the sliding groove 701, one end of the spring 702 is fixedly connected to the bottom surface of the sliding groove 701, the other end of the spring 702 is fixedly connected to the sliding column 703, and the sliding direction of the sliding column 703 is the butt joint direction of the two terminals.

[0045] When the two terminals are butt jointed, the sliding column 703 abuts against the end surface of the shell 501 and applies an elastic force, so that the clamping block 601 is more stably abutted against the clamping groove 602. In addition, when a short circuit occurs at the terminal and the fuse device 5 melts, the shell 501 after melting can be separated from the male terminal 2 and the female terminal 1 in the butt joint by the elastic force, so as to automatically disconnect the circuit.

[0046] The damaged fuse device 5 after melting can be replaced with a new one at any time, and then is threadedly sleeved on the protective sleeve 4 of the male terminal 2, so as to continue to perform the short circuit melting work.

[0047] Further, the protective shell 3 and the fuse device 5 are externally provided with an electricity-eliminating layer 8, and the protective shell and the protective sleeve 4 are externally provided with an anti-skid layer 9.

[0048] Please refer to Figure 4 In the embodiment, the static electricity eliminating layer 8 is composed of a plurality of metal sheets arranged uniformly and used for absorbing static electricity, and the metal sheets are connected with a grounding wire (not shown in the figure) fixed on the outer wall of the insulating rubber of the cable, and the grounding end of the grounding wire is located in the external environment, so that the cable can be grounded with the external environment after being installed and fixed, and the static electricity is eliminated.

[0049] Preferably, the metal sheets have conductivity, and static electricity is generated when the worker contacts various objects in the external dry environment, so that the static electricity generated when the worker contacts the outside of the entire connecting assembly is absorbed in advance by the metal sheets, and the static electricity generated when the worker contacts the radio frequency cable and the terminal in the subsequent process is avoided, and a safety accident is caused.

[0050] In the embodiment, the static electricity eliminating layer 8 is composed of a plurality of metal sheets arranged uniformly and used for absorbing static electricity, and the metal sheets are connected with a grounding wire (not shown in the figure) fixed on the outer wall of the insulating rubber of the cable, and the grounding end of the grounding wire is located in the external environment, so that the cable can be grounded with the external environment after being installed and fixed, and the static electricity is eliminated.

[0051] In the embodiment, the anti-skid layer 9 is an insulating rubber layer, and the surface of the insulating rubber layer is rough, so that the worker can contact the cable circuit and plug the terminal, and the frictional resistance is provided for the worker, so that the worker can be plugged better, and the slipping is avoided.

[0052] The embodiments of the utility model have been described in detail. In order to avoid shielding the concept of the utility model, some details known in the art are not described. According to the above description, those skilled in the art can understand how to implement the technical solutions of the utility model, and the scope of the utility model is defined by the appended claims.
