The junction between the connector and the patch cord cable typically features a molded part or heat-shrink tubing (collectively referred to as a protective sleeve) to protect the soldered area between the connector and the cable.

[0003] However, the protective sleeves at the junctions of patch cords, connectors, and cables are easily damaged by birds and / or by environmental factors, which can easily cause a series of problems such as short circuits or failures of RF patch cords. Utility Model Content

[0004] In view of the above-mentioned defects or improvement needs of the prior art, the present invention provides an alternative, the purpose of which is to not only protect the entire RF jumper but also reduce the external force acting on the RF jumper, and also to enable convenient assembly of the housing, ensuring the ease of processing.

[0005] To achieve the above objectives, this utility model provides a protection device for radio frequency jumpers, the protection device comprising a sleeve and two housings;

[0006] The sleeve has grooves on the outer peripheral walls at both ends. The sleeve is used to slidably fit over the jumper cable. Each shell includes two arc-shaped half-shell bodies. The two arc-shaped half-shell bodies are detachably connected to form a tubular structure for slidably fitting a protective sleeve. One end of the inner peripheral wall of each arc-shaped half-shell body is provided with a toothed portion, which engages with the corresponding groove.

[0007] Optionally, each of the arc-shaped semi-shell bodies has a plurality of spaced first positioning protrusions and first positioning grooves on its two sides, and each first positioning protrusion is detachably inserted into the corresponding first positioning groove.

[0008] Optionally, a notch is provided on one side of each of the said arc-shaped semi-shell bodies.

[0009] Optionally, each of the arc-shaped semi-shell bodies has a connecting shaft on one side and an arc-shaped buckle on the other side, the arc-shaped buckle being detachably snapped onto the corresponding connecting shaft.

[0010] Optionally, each of the arc-shaped semi-shell bodies has a first cylinder and a second cylinder on its two sides, the first cylinder and the second cylinder are staggered, and one end of the first cylinder and one end of the second cylinder have a slot arranged coaxially. The two slots are detachably fitted with pins. Each of the arc-shaped semi-shell bodies has a second positioning protrusion and a second positioning groove on its two sides, and each second positioning protrusion is detachably fitted into the corresponding second positioning groove.

[0011] Optionally, one end of the inner peripheral wall of each of the arc-shaped semi-shell bodies has stepped portions arranged sequentially along the axial direction of the arc-shaped semi-shell body, and the toothed portions are provided on the inner peripheral wall of each stepped portion.

[0034] Example:

[0035] Figure 1 This is a schematic diagram illustrating the use of a protection device for radio frequency jumpers provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the protective device includes a sleeve 1 and two housings 2.

[0036] The sleeve 1 has grooves 11 on the outer peripheral walls at both ends. The sleeve 1 is used to slidably fit over the jumper cable 100. Each housing 2 includes two arc-shaped half-shell bodies 21. The two arc-shaped half-shell bodies 21 are detachably connected to form a tubular structure for slidably fitting the protective sleeve 300. One end of the inner peripheral wall of each arc-shaped half-shell body 21 is provided with a toothed part 22, which engages with the corresponding groove 11.

[0037] The protective device for RF jumpers provided in this embodiment of the present invention has grooves 11 on the outer peripheral walls of both ends of the sleeve 1 and teeth 22 on the inner peripheral wall of one end of each arc-shaped half-shell body 21. The teeth 22 engage with the grooves 11, which allows the sleeve 1 and the two shells 2 to form a whole and slide relative to the RF jumper. This protects the entire RF jumper while reducing external forces acting on it, thus preventing the RF jumper from being pecked by birds and / or damaged by environmental factors, which could cause short circuits or failures.

[0038] Furthermore, since each housing 2 includes two arc-shaped half-shell bodies 21, and the two arc-shaped half-shell bodies 21 are detachably connected, the housing 2 can be conveniently assembled (during processing, the sleeve 1 is first fitted onto the jumper cable 100, and then the housing 2 is fitted onto the connector 200 and the jumper cable 100 after welding), ensuring the convenience of processing and avoiding interference between the welding of the connector 200 and the jumper cable 100 due to the pre-fitting of each housing 2.

[0039] In other words, the protective device for RF jumpers provided by this utility model embodiment can not only protect the entire RF jumper but also reduce the external force acting on the RF jumper. It can also facilitate the assembly of the housing 2, ensuring the ease of processing.

[0040] For example, each arc-shaped semi-shell body 21 is made of metal or rigid plastic. The rigid plastic part can be PA6 or PC, and the metal part can be aluminum alloy or copper, requiring a certain hardness to protect the jumper cable 100 and protective sleeve 300 from damage, and facilitating processing. Furthermore, the arc-shaped semi-shell body 21 can be processed in various ways, including machining, mold making, and stamping.

[0041] For example, the sleeve 1 can be a nylon tube, which has a certain degree of flexibility to facilitate fitting around the periphery of the jumper cable 100. In addition, multiple annular grooves are formed along the axial direction on the outer periphery of the nylon tube, which can serve as grooves 11 for engaging with the toothed portion 22, thus eliminating the need for additional machining of the grooves 11.

[0042] Figure 2 This is a schematic diagram of the structure of the first type of shell provided in this embodiment of the utility model, as shown below. Figure 2As shown, each of the arc-shaped semi-shell bodies 21 has multiple spaced first positioning protrusions 211 and first positioning grooves 212 on its two sides, and each first positioning protrusion 211 is detachably inserted into the corresponding first positioning groove 212.

[0043] In the above embodiments, the two arc-shaped half-shell bodies 21 can be reliably connected by the insertion and cooperation of multiple first positioning protrusions 211 and multiple first positioning grooves 212.

[0044] Specifically, each of the arc-shaped semi-shell bodies 21 has one first positioning protrusion 211 and two first positioning grooves 212 on one side, and two positioning protrusions and one first positioning groove 212 on one side. The structures of the two arc-shaped semi-shell bodies 21 are completely identical and can be directly assembled, thus achieving foolproof assembly, ensuring convenient assembly of the two arc-shaped semi-shell bodies 21, improving work efficiency, and greatly saving costs.

[0045] Furthermore, a notch 213 is provided on one side of each arc-shaped semi-shell body 21.

[0046] It is easy to understand that after the two arc-shaped half-shell bodies 21 are assembled, the notch 213 allows for convenient disassembly and assembly of each shell 2, thus facilitating later maintenance.

[0047] Figure 3 This is a schematic diagram of the structure of the second type of shell provided in this embodiment of the utility model, as shown below. Figure 3 As shown, each of the arc-shaped semi-shell bodies 21 has a connecting shaft 214 on one side and an arc-shaped buckle 215 on the other side, which is detachably snapped onto the corresponding connecting shaft 214.

[0048] Specifically, before installing the housing 2, a set of connecting shafts 214 and arc-shaped buckles 215 on the two arc-shaped semi-shell bodies 21 can be pre-assembled together to ensure that one side of the two arc-shaped semi-shell bodies 21 is hinged in advance. When installing the housing 2, the connecting shaft 214 is used as the hinge axis, and the other set of connecting shafts 214 and arc-shaped buckles 215 on the two arc-shaped semi-shell bodies 21 are brought closer to each other, thereby completing the connection of the other set of connecting shafts 214 and arc-shaped buckles 215.

[0049] It is easy to understand that by pre-assembling a set of connecting shafts 214 and arc-shaped buckles 215, assembly efficiency can be improved when actually assembling the housing 2. In addition, the two arc-shaped half-shell bodies 21 have completely identical structures and can be directly assembled, thus also achieving foolproof design, ensuring convenient assembly of the two arc-shaped half-shell bodies 21, improving work efficiency, and greatly saving costs.

[0050] Figure 4 This is a schematic diagram of the structure of the third type of shell provided in this embodiment of the utility model, as shown below. Figure 4 As shown, each of the two sides of the arc-shaped semi-shell body 21 is provided with a first cylinder 216 and a second cylinder 217 (the axis of each cylinder is parallel to the axis of the tubular structure). The first cylinder 216 and the second cylinder 217 are staggered, and one end of the first cylinder 216 and one end of the second cylinder 217 are provided with a slot 220 arranged coaxially. The two slots 220 are detachably fitted with pins 221. Each of the two sides of the arc-shaped semi-shell body 21 is provided with a second positioning protrusion 218 and a second positioning groove 219. Each second positioning protrusion 218 is detachably fitted into the corresponding second positioning groove 219.

[0051] In the above embodiment, before installing the housing 2, one side of each of the two arc-shaped semi-shell bodies 21 is simultaneously inserted into the two cylinders via the two ends of the pin 221, thus achieving a hinge connection on one side of the two arc-shaped semi-shell bodies 21. During the installation of the housing 2, the pin 221 serves as the hinge axis, and the second positioning protrusion 218 and the second positioning groove 219 of the two arc-shaped semi-shell bodies 21 are brought closer together, thereby completing the connection on the other side of the two arc-shaped semi-shell bodies 21, improving assembly efficiency.

[0052] It should be noted that in other embodiments of this utility model, the two arc-shaped semi-shell bodies 21 can also be detachably connected by bolts or clamps, etc., and this utility model does not limit this.

[0053] Figure 5 This is an assembly diagram of the arc-shaped semi-shell body and the sleeve provided in this embodiment of the utility model, as shown below. Figure 5 As shown, one end of each arc-shaped semi-shell body 21 has a stepped portion 23 arranged sequentially along the axial direction of the arc-shaped semi-shell body 21 on its inner peripheral wall, and a toothed portion 22 is provided on the inner peripheral wall of each stepped portion 23.

[0054] In the above embodiments, for jumper cables 100 of different diameters (e.g., 1 / 2 inch or 7 / 8 inch), the inner diameter of the corresponding sleeve 1 is different. By providing multiple stepped portions 23 and providing toothed portions 22 on the inner peripheral wall of the corresponding stepped portions 23, it is possible to be compatible with the connection of sleeves 1 of different sizes, realize the universality of the housing 2, and thus reduce the production cost.

[0055] In addition, the larger the diameter of the jumper cable 100, the shorter the required length of the sleeve 1.

[0056] Figure 6 This is a schematic diagram of the use of the arc-shaped semi-shell body provided in this embodiment of the utility model, as shown below. Figure 6As shown, each of the inner circumferential walls at both ends of the arc-shaped semi-shell body 21 is provided with a toothed portion 22. The toothed portion 22 on the right side can be engaged in the groove 11 of the sleeve 1, while the toothed portion 22 on the left side can be located in the positioning groove 400 formed between the protrusion of the connector 200 and the protective sleeve 300, and achieves limiting. This not only ensures that the toothed portion 22 on the left side is properly engaged in the positioning groove 400 when the housing 2 is installed, but also avoids the problem of the protective sleeve 300 being exposed and damaged due to the housing 2 shifting to the right during use.

[0057] In addition, compared to providing a toothed portion 22 only at one end, providing a toothed portion 22 on the inner peripheral walls of both ends of each arc-shaped half-shell body 21 can further achieve foolproof (i.e. there is no distinction between left and right ends), and can further speed up the assembly efficiency of the two arc-shaped half-shell bodies 21.

[0058] In this embodiment, waterproof pads (not shown) are provided on both sides of each arc-shaped half-shell body 21. During the assembly of the two arc-shaped half-shell bodies 21, the gaps formed between the two arc-shaped half-shell bodies 21 are filled by clamping the waterproof pads to prevent rainwater from seeping in.

[0059] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
