[0024] The present utility model will be described in detail below by referring to the drawings and in conjunction with the embodiments:

[0025] Embodiment 1

[0026] The present utility model provides a protection device for the port jumper of a vector network analyzer. By providing a bottom plate 2 matching the jumper connector on the jumper protection cover plate 1 and installing the jumper protection cover plate 1 on the jumper, the jumper protection cover plate 1 can protect the jumper and prevent direct impact on the jumper during handling and transportation.

[0027] In this embodiment, since a number of port groups are provided on the front panel of the vector network analyzer, each port group is composed of three jumpers arranged horizontally in sequence, and a jumper group is composed of an upper port and a lower port arranged vertically. The upper port and the lower port in the jumper group are connected by a jumper and a jumper connector. Thus, in order to protect the jumper from direct damage, the vector network analyzer port jumper protection device is installed on the jumper.

[0028] The vector network analyzer port jumper protection device includes a jumper protection cover plate 1. The jumper protection cover plate 1 is a U-shaped plate, and the U-shaped plate is composed of a top plate 11 and side plates 12 provided on both sides of the top plate 11. The side plates 12 are also provided with fixing plates 13 with bends facing the opening. Screw holes 132 are provided on the fixing plates 13, and screws are connected in the screw holes 132. The bottom plate 2 can be fixed to the fixing plates 13 by screws, so that a bottom plate 2 is detachably arranged at the opening of the U-shaped plate through screws.

[0029] A round hole matching the diameter of the jumper connector is provided on the bottom plate 2. Then the jumper can be located inside the jumper protection cover plate 1 through the round hole. Not only can the jumper be fixed through the round hole, but also the jumper can be protected by the top plate 11 of the jumper protection cover plate 1 to avoid directly impacting the jumper during handling and transportation, resulting in jumper deformation or damage. Moreover, a semi-circular groove 131 can be provided on the fixing plate 13 according to the round hole provided on the bottom plate 2, so that the semi-circular grooves 131 on the two fixing plates 13 are arranged oppositely, and a cavity is formed between the oppositely arranged semi-circular grooves 131 for the jumper connector to pass through.

[0030] The jumper protection cover plate 1 can be used to protect the jumpers of one port group. One port group has three jumpers arranged horizontally. Then three through holes 121 corresponding to the jumpers are arranged horizontally on the bottom plate 2, and two vertically arranged round holes are provided in one through hole 121 for fixing the cable.

[0031] Specifically, such as Figure 1 、 Figure 2 、 Figure 3As shown, a through hole 121 formed by connecting an upper circular hole and a lower circular hole is provided at the center of the bottom plate 2 for fixing the cables of the upper port and the lower port. In order to facilitate the installation of the jumper protection cover plate 1 on the jumper through the bottom plate 2, two vertically extending card slots 3 are symmetrically provided on the bottom plate 2. The inner side of the card slot 3 is connected to the outer side of the bottom plate 2. One end of the card slot 3 is open upward. Two semi-circular holes A8 are vertically arranged on the right side of the card slot 3. A guide rail 4 extending in the vertical direction is provided on the left side of the card slot 3. A slider 5 is connected to the guide rail 4. Two semi-circular holes B9 are vertically arranged on the side of the slider 5 facing the right side of the card slot 3. One semi-circular hole A8 and one semi-circular hole B9 are correspondingly arranged to form two vertically arranged circular holes. Then, the two vertically arranged circular holes are connected to form a through hole 121 for fixing a jumper. Moreover, the formation of the circular holes by the slidably connected skateboard enables the disassembly and assembly of the jumper, which is convenient for operation.

[0032] Specifically, the slider 5 can slide up and down on the guide rail 4. When the slider 5 slides into the card slot 3 through the guide rail 4, two vertically arranged circular holes are formed to achieve the fixing effect on the jumper. However, the guide rail 4 is a T-shaped guide rail 4. A guide groove 6 is provided on the side of the slider 5 away from the right side of the card slot 3. The T-shaped guide rail 4 is formed by a head and a tail. The bottom end of the tail is fixedly connected to the left side of the card slot 3. The head is located in the guide groove 6, and both ends of the head extend along both sides of the guide groove 6. Fixing parts for clamping the two ends of the head are symmetrically provided at the front end of the guide groove 6. The slider 5 mainly slides by the clamping of the fixing parts and the head. Therefore, in this embodiment, a pressing block 7 is further provided for the slider 5. The pressing block 7 presses the slider 5 tightly in the radial direction of the jumper connector to prevent the slider 5 from moving along the extending direction of the tail.

[0033] Specifically, the length of the guide groove 6 is less than the length of the T-shaped guide rail 4. A pressing block 7 is provided above the guide groove 6. A groove is provided on the pressing block 7, enabling the top end of the T-shaped guide rail 4 to be embedded in the groove, and the pressing block 7 is fixed to the top end of the T-shaped guide rail 4 by screws. Moreover, the end face of the groove is closely attached to the upper surface of the guide groove 6. Both the end face of the groove and the upper surface of the guide groove 6 are set as 45° inclined planes. The purpose is that when the pressing block 7 moves downward, it will force the inclined plane of the slider 5 to rise. Even if the slider 5 moves to both sides, the pressing block 7 can be pressed downward to push the slider 5 to be tightly pressed in the radial direction of the jumper connector, thereby achieving the fixing effect on the jumper. At this time, the bottom plate 2 is closely attached to the inner side of the fixing plate 13. The upper and lower ends of the bottom plate 2 are respectively closely attached to the two side plates 12. A through hole 121 adapted to the pressing block 7 is provided on the side plate 12. The through hole 121 is located above the pressing block 7, and the pressing block 7 is fixed to the top end of the T-shaped guide rail 4 by screws passing through the through hole 121.

[0034] Based on the above settings, when assembling the vector network analyzer port jumper protection device, the sliders 5 on both sides can be first sleeved onto the T-shaped guide rail 4. Then, the pressing block 7 is sleeved onto the top of the T-shaped guide rail 4, and then the pressing block 7 is locked to the top of the T-shaped guide rail 4 by screws. Thus, the slider 5 is fixed in the card slot 3. Then, the assembled bottom plate 2 is sleeved into the jumper protection cover plate 1, and the bottom plate 2 is fixed to the jumper protection cover plate 1 by screws.

[0035] When using the vector network analyzer port jumper protection device, the screws on the pressing block 7 can be loosened so that both the sliders 5 on both sides and the pressing block 7 are in a loose state. Then, the vector network analyzer port jumper protection device is sleeved onto the jumper. At this time, the screws on the pressing block 7 are tightened. And when tightening the screws on the pressing block 7, the screws will move downward, forcing the pressing block 7 to move downward. Since both the groove end face of the pressing block 7 and the guide groove 6 of the slider 5 are 45° bevels, when the pressing block 7 moves downward, it will force the inclined surface of the slider 5 to lift, that is, the slider 5 moves to both sides. It can also be pushed by the downward pressure of the pressing block 7 to tightly press the slider 5 in the radial direction of the jumper connector, so as to achieve the fixing effect on the jumper. And when it is necessary to remove the vector network analyzer port jumper protection device from the jumper, it can be achieved only by loosening the screws on the pressing block 7.

[0036] In summary, the present invention provides a vector network analyzer port jumper protection device. The vector network analyzer port jumper protection device is simple to use, firmly fixed, and can effectively protect the jumper, avoiding direct impact on the jumper during handling and transportation.

[0037] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
