Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, and specifically relates to a connection device for coaxial cables. Background Art

[0002] A magnetron is a microwave generator, which is commonly used in the field of rehabilitation medicine. The connection between the magnetron and the coaxial cable is a common connection method. The fixed position of the magnetron has a certain impact on both the energy consumption and temperature of the coaxial cable transmitting microwave signals.

[0003] One end of the existing coaxial cable is usually fixed on the magnetron located at the bottom of the device. Some magnetrons are placed obliquely or horizontally, resulting in a large bending degree of the coaxial cable inside the device. At the same time, the coaxial cable inside the device is also prone to changes in the angle of the coaxial cable inside the device due to external pulling, and it is also easy to wear the connection between the coaxial cable and the magnetron. Therefore, it affects the signal power loss of the coaxial cable. To solve the above technical problems, a connection device for coaxial cables is proposed. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem of unstable signal power loss of coaxial cables in the prior art, and thus a connection device for coaxial cables is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A connection device for coaxial cables includes a housing and a magnetron and a transformer installed inside the housing. The magnetron is arranged above the transformer, and the transformer supplies power to the magnetron; two symmetrically arranged coaxial cables are connected above the magnetron. The other ends of the two coaxial cables respectively penetrate through both side ends of the housing and are connected to microwave probes located at the side ends of the housing; a first mounting plate located above the magnetron is also installed inside the housing, and a connecting piece for fixing the coaxial cable is connected to the first mounting plate. The connecting piece is also used to limit the bending degree of the coaxial cable between the magnetron and the connecting piece.

[0006] Preferably, the magnetron and the transformer are arranged in layers, and the transformer is installed at the bottommost end of the housing.

[0007] Preferably, the position of the microwave probe is adjustable.

[0008] Preferably, the connecting piece includes a first connecting plate fixed on the first mounting plate and a second connecting plate fixed on the first connecting plate. The coaxial cable is clamped between the first connecting plate and the second connecting plate.

[0009] Preferably, the first connecting plate has a straight plate structure or a bent plate structure; an arched bending part is arranged in the middle of the second connecting plate; a connecting hole is further arranged at the end of the second connecting plate. The first connecting plate and the second connecting plate are fixedly arranged with each other through the connecting hole, and the coaxial cable is fixed between the first connecting plate and the second connecting plate.

[0010] Preferably, a second mounting plate is installed inside the housing and located below the first mounting plate. The second mounting plate is horizontally fixed inside the housing, and a magnetron is fixedly connected to the upper end surface of the second mounting plate.

[0011] Preferably, the number of magnetrons is two, and they are symmetrically and vertically distributed, with the transformer located below the second mounting plate.

[0012] Preferably, angle-adjustable support arms are installed at both side ends of the housing, and a microwave probe is installed at the upper end of the support arm.

[0013] Beneficial effects: In this technical solution, both the magnetron and the transformer are installed inside the housing. The magnetron is located above the transformer. One end of each of the two coaxial cables penetrates through both side ends of the housing and is connected to the microwave probe located at the side end of the housing. By increasing the installation height of the magnetron, the length of the coaxial cable is reduced. One end of the coaxial cable is fixed to the top of the magnetron, further reducing the length of the coaxial cable, thereby reducing the signal power loss and heating temperature of the coaxial cable. A first mounting plate is further installed inside the housing and located above the magnetron. A connecting piece for fixing the coaxial cable is connected to the first mounting plate. Even if the angle of the microwave probe is adjusted, the coaxial cable placed inside the housing will not bend or change in length, avoiding unstable signal power loss and heating temperature of the coaxial cable.

[0021] Refer to Figures 1 - 3 , an embodiment provided by the present utility model, a coaxial cable connection device, includes a housing 1, a magnetron 5 and a transformer 6 installed inside the housing 1. Among them, the magnetron 5 and the transformer 6 are arranged in layers, and the magnetron 5 is arranged above the transformer 6;

[0022] The transformer 6 supplies power to the magnetron 5, and the transformer 6 is installed at the lowermost end of the housing 1;

[0023] Two symmetrically arranged coaxial cables 4 are connected above the magnetron 5. The other ends of the two coaxial cables 4 respectively penetrate through both side ends of the housing 1 and are connected to a microwave probe 3 located at the side end of the housing 1, wherein the position of the microwave probe 3 is adjustable;

[0024] A first mounting plate 11 located above the magnetron 5 is further installed inside the housing 1. A connecting member for fixing the coaxial cable 4 is connected to the first mounting plate 11, and the connecting member is also used to limit the bending degree of the coaxial cable 4 between the magnetron 5 and the connecting member.

[0025] In this embodiment, the magnetron 5 and the transformer 6 are both installed inside the housing 1. The magnetron 5 is located above the transformer 6, and the length of the coaxial cable 4 is reduced by increasing the installation height of the magnetron 5. One end of the coaxial cable 4 is fixed to the top of the magnetron 5, further reducing the length of the coaxial cable 4, thereby reducing the signal power loss and the heating temperature of the coaxial cable 4. Inside the housing 1, there is also a first mounting plate 11 located above the magnetron 5. A connecting member for fixing the coaxial cable 4 is connected to the first mounting plate 11, so that even if the angle of the microwave probe 3 is adjusted, the coaxial cable 4 placed inside the housing 1 will not bend or change in length, avoiding unstable signal power loss and heating temperature of the coaxial cable 4. At the same time, it also prevents the temperature of the transformer 6 from affecting the coaxial cable 4 placed inside the housing 1.

[0026] As a further improved embodiment, the connecting member includes a first connecting plate 111 fixed to the first mounting plate 11 and a second connecting plate 112 fixed to the first connecting plate 111. The coaxial cable 4 is clamped between the first connecting plate 111 and the second connecting plate 112.

[0027] The first connecting plate 111 has a straight plate structure or a bent plate structure, and the middle part of the second connecting plate 112 is provided with an arched bending part.

[0028] The end of the second connecting plate 112 is also provided with a connecting hole 113. By providing the connecting hole 113, the first connecting plate 111 and the second connecting plate 112 are fixedly arranged with each other, and the coaxial cable 4 is fixed between the first connecting plate 111 and the second connecting plate 112.

[0029] In this embodiment, by providing the first connecting plate 111 and the second connecting plate 112, the coaxial cable 4 inside the housing 1 will not bend or change in length, thereby preventing unstable signal power output at the connection between the coaxial cable 4 and the magnetron 5.

[0030] As a further improved embodiment, a second mounting plate 12 is installed inside the housing 1 below the first mounting plate 11, and the second mounting plate 12 is horizontally fixed inside the housing 1.

[0031] The upper end surface of the second mounting plate 12 is fixedly connected to the magnetron 5.

[0032] The number of the magnetrons 5 is two, and they are symmetrically and vertically distributed; effectively reducing the length of the coaxial cable 4, facilitating the coaxial cable 4 to pass through the side end of the housing 1, and also reducing the bending degree at the end connection of the coaxial cable 4.

[0033] The transformer 6 is located below the second mounting plate 12.

[0034] In this embodiment, by arranging the second mounting plate 12 between the magnetron 5 and the transformer 6, the heat generated by the transformer 6 is effectively prevented from spreading to the coaxial cable 4.

[0035] As a further improved embodiment, angle-adjustable support arms 2 are installed at both ends of the housing 1, and a microwave probe 3 is installed at the upper end of the support arm 2.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
