Description

Cluster radio frequency connector jumper assembly, jumper unit and bird prevention device

Technical Field

The utility model relates to a radio frequency connector wire jumper subassembly tied in a bundle, wire jumper unit and an anti-bird device, they have and prevent the bird pecking function.

Background

Existing bundled connector assemblies include a plastic housing having a plurality of through-holes (e.g., 4 or 5) in which a cable connector can be received in each through-hole, respectively, such that the housing can securely receive the connectors of a plurality of cables together, thereby facilitating the installation of the plurality of cables on the antenna.

However, since the housing of the cluster connector assembly is made of plastic and the cable sheath is directly exposed to the external environment, the housing and the cable sheath are easily pecked by birds. If the cluster connector assembly is used directly in a bird-prone environment, such as in the australian market, the plastic housing and cable jacket are susceptible to being pecked by birds, such as parrots, laughter and/or australian parrots.

Currently, on the australian market, existing bird pecking prevention connector assemblies do not have the aforementioned housing capable of accommodating a plurality of cable connectors at the same time, but each assembly comprises only one individual cable on which a plastic tube for bird pecking prevention is sheathed.

Practice has shown that the diameter of the plastic tube should be ≥ 21mm in order to have a locally required bird pecking prevention function. However, such large diameter plastic tubes cannot be used for the above-mentioned bundled connector assembly of the present applicant because, due to the limited size of the housing, a plurality of such large diameter plastic tubes interfere and press with each other after being installed in the housing, thereby causing bending of portions of the respective cables close to the housing. If the cable is excessively bent (i.e., bent by an amount greater than the minimum bend radius of the cable) over a portion of its length (30-50mm) near the housing end connector, the performance of the cable is very adversely affected, i.e., the transmission return loss and third-order intermodulation of the cable are increased. It is also disadvantageous that the plastic tubes are completely sealed, so that condensation water entering the plastic tubes due to diurnal temperature differences or rain cannot escape to the outside environment, which may damage the components inside the tubes.

It is to be noted herein that various modifications and changes in form and detail with respect to the embodiments may be made without departing from the general inventive concept.

Fig. 1 and 2 show an embodiment of the bundled rf connector jumper assembly 1 of the present invention. Here, fig. 1 shows a perspective view of the bundled radio frequency connector jumper assembly 1 in an installed state, and fig. 2 shows a perspective view of the bundled radio frequency connector jumper assembly 1 in a partially exploded state.

As can be seen from fig. 1 and 2, the bundled radio frequency connector jumper assembly 1 may include a plurality of jumper units 2 (5 are shown as an example in the drawings) and a housing 3 for integrating one end of each jumper unit 2 together. Each jumper unit 2 may include a cable 5 (see fig. 4b, 4c), and first and

second connectors

4, 6 connected at opposite ends of the cable 5, respectively. The first connector 4 may be connected together with an adapting connector of a base station antenna. The second connector 6 may be connected to an RRU (radio remote unit, not shown) and may be, for example, a 4.3-10 connector. The housing 3 has a plurality of through holes 10. The first connectors 4 may be accommodated in the through holes 10 of the housing 3 and all the first connectors 4 are connected together with the mating connector (not shown) of the base station antenna by one connecting operation of the housing 3.

In order to prevent the cable 5 and the housing 3 from being pecked by birds, it is necessary to protect them from birds. Fig. 3a is a schematic view of an embodiment of the bird prevention device 7 with a bird pecking prevention function according to the present invention. The bird repellent device 7 may be fitted over the cable 5 of the jumper unit 2 to protect it from bird pecking. The bird guard 7 may comprise a hollow conduit 11 housing the cable 5. Both ends of the conduit 11 may be provided with hollow first and second end caps 12, 13, respectively, to enclose the ends of the conduit 11. The first end cap 12 may be connected with a fixing sleeve 20, which may fix the first connector 4 in the housing 3. The second end cap 13 may be connected with the second connector 6.

The first end cap 12 may include a conduit-side connection 14 for connection with an end of the conduit 11 and a sleeve-side connection 15 for connection with the fixed sleeve 20. The second end cap 13 may comprise a conduit side connection 18 for connection with an end of the conduit 11 and a connector side connection 19 for connection with the second connector 6. The inner diameters of the first and second end caps 12, 13 may at least allow the cable 5 to pass through.

The conduit-side connection 14 of the first endcap 12 and the conduit-side connection 18 of the second endcap 13 can be connected with the conduit 11 in a variety of ways. For example, fig. 3b shows the pressure-welded connection between the conduit-side connection portion 14 of the first cap 12 or the conduit-side connection portion 18 of the second cap 13 and the conduit 11, that is, the conduit-side connection portion 14 of the first cap 12 or the conduit-side connection portion 18 of the second cap 13 is fitted around one end portion of the conduit 11, and the overlapping portion of the two is pressed and deformed to form a fixed connection. Fig. 3c shows that the tube-side connection 14 of the first endcap 12 or the tube-side connection 18 of the second endcap 13 is connected with the tube 11 by a crimping process. The dimensions of the tube-

side connection

14, 18 are smaller than the outer diameter of the tube 11 by the crimping process, so that the tube-

side connection

14, 18 can at least partially grip into the helical groove of the tube 11 to achieve a fixed connection. Fig. 3d shows a threaded connection of the conduit-side connection 14 of the first endcap 12 or the conduit-side connection 18 of the second endcap 13 with the conduit 11, i.e. the conduit-side connection 14 of the first endcap 12 or the conduit-side connection 18 of the second endcap 13 may be provided with an internal thread and the end of the conduit 11 may be provided with an external thread. The ends of the conduit 11 may be screwed into the conduit-

side connections

14, 18 of the end cap to form a threaded connection therebetween.

In some embodiments, the sleeve-side connection 15 of the first end cap 12 may have an outer diameter that is smaller than the outer diameter of the conduit-side connection 14, while the connector-side connection 19 of the second end cap 13 may have an outer diameter that is substantially equal to the outer diameter of the conduit-side connection 14, as can be seen in fig. 3 a. In other embodiments, the outer diameter of the sleeve-side connection 15 of the first end cap 12 may also be greater than or equal to the outer diameter of the conduit-side connection 14; the outer diameter of the connector-side connection 19 of the second end cap 13 may also be larger or smaller than the outer diameter of the catheter-side connection 14.

The first end cap 12 can rest with its sleeve-side connection 15 on the fixing sleeve 20 and the second end cap 13 can rest with its connector-side connection 19 on the second connector 6. In some embodiments, instead of abutting, the sleeve-side connection 15 and the connector-side connection 19 of the first and second end caps 12, 13 can also be connected releasably or unreleasably to the fixing sleeve 20 and the second connector 6, respectively, for example a form-locking connection, such as a snap connection or a screw connection, or a material-locking connection, such as a welded connection or an adhesive connection.

In order to abut the first and second end caps 12, 13 against the fixing sleeve 20 and the second connector 6, respectively, the total length of the conduit 11 and the first and second end caps 12, 13 after assembly may be slightly or significantly greater than the length of the cable 5, and the conduit 11 may have a certain elasticity in the longitudinal direction. The total length of the conduit 11 and the first and second end caps 12, 13 in the relaxed state may be greater than the length of the cable 5. When the bird guard 7 is mounted on the cable 5, the first and second end caps 12, 13 of the bird guard 7 may be abutted between the fixing sleeve 20 and the second connector 6 by the tension of the conduit 11. Thereby, the

respective end caps

12, 13 and the conduit 11 can completely cover the cable 5 for bird pecking protection thereof.

In order to simply achieve the elasticity of the duct 11 in the longitudinal direction, the duct 11 may be spirally wound from a metal strip or braided from a metal strip. The conduit 11 made of a metal strip may have a certain elasticity in the longitudinal direction like a spring and may also have a certain flexibility. The conduit 11 may be a single-or double-button metal hose. Two

end caps

12, 13 may be fixedly attached to both ends of the conduit 11 to secure the metal strips at both ends of the conduit 11 and prevent the metal strips at both ends from scratching a person. Where the end caps 12, 13 are threadably connected to the conduit 11 as described above, the external threads of the end of the conduit 11 may be formed by the wound metal strip itself. Furthermore, in contrast to sealed plastic pipes, the metal ducts 11 made of metal strips may be unsealed in their circumferential direction, so that the condensation water entering the bird repelling device 7 due to diurnal temperature differences or rain can be drained to the outside environment at any time without damaging the devices housed inside the metal ducts 11.

In some embodiments, the conduit 11 may be a non-coiled, sealed metal conduit, such as a helical bellows, which may be made by a drawing process or from a metal strip that is rolled and welded. The helical bellows may have a small bending radius.

The conduit 11 and the end caps 12, 13 at both ends thereof may be made of metal, such as non-magnetic stainless steel, aluminum alloy, or the like. Compared to plastic materials, the wall of the pipe 11 made of metal can be significantly thinner while ensuring strength and bird pecking prevention, so that the outer diameter of the pipe 11 can be smaller. Experiments prove that the outer diameter of the metal bird repelling device 7 can be made to be less than 14 mm. The metal pipe with small outer diameter can be used for replacing a plastic pipe with the diameter being more than or equal to 21mm commonly used in the Australian market at present and is applied to a bundling connector component.

The small outer diameter of the guide tube 11 of the metal bird repelling device 7 ensures that the jumper units 2 are not excessively bent due to the mutual compression due to the small space on the housing 3 after being installed in the housing 3. It is important that a length of the cable 5 close to the first connector 4 (e.g. 30-50mm in length) be kept as straight as possible, since excessive bending of this part can significantly reduce the performance of the cable 5. The conduit 11 of the bird guard 7 may have a uniform small outer diameter. In some embodiments, the conduit 11 of the bird guard 7 may have a non-uniform outer diameter, but should be ensured to have a small outer diameter at the portion near the fixing sleeve 20 to prevent the bird guard 7 from being crushed and bent against each other. Therefore, the utility model discloses a jumper assembly 1 can still guarantee that its wire 8 is the straight line basically in the part that is close to first connector 4 despite the existence of metal anti-bird device 7, thereby the utility model discloses a metal anti-bird device 7 can realize preventing the bird pecking function, can not lead to the interference of cable 5 based on its little external diameter again.

Fig. 4a to 4c show schematic views of the jumper unit 2 with the bird guard 7 installed, wherein fig. 4b and 4c show enlarged cross-sectional views of both ends of the jumper unit 2, respectively. As described above, based on the elasticity of the conduit 11 of the bird guard 7, the length of the conduit 11 in a relaxed state may be greater than the length of the cable 5, so that the bird guard 7 may be in a tensioned state after the bundled radio frequency connector jumper assembly 1 is installed.

Referring to fig. 4a and 4b, the jumper unit 2 comprises a nut 23 fixed on the circumference of the second connector 6, which nut 23 can fix the second connector 6 to the RRU. Due to the tension of the guide tube 11, the free end face of the connector-side connection portion 19 of the second end cap 13 abuts against the end face of the nut 23 of the second connector 6 of the cable 5. The tube side connection 18 of the second end cap 13 may be crimped or screwed onto the tube 11. The guide tubes 11 may be spaced slightly apart or abut directly against the outer skin 9 of the cable 5 to protect the cable 5 from bird pecking. In some embodiments, the inner diameter of the second end cap 13 may be larger than the outer diameter of the second connector 6 and its nut, so that when the second connector 6 is connected to an RRU, the second end cap 13 of the bird guard 7 may rest on the RRU or an attachment thereof over the second connector 6 and its nut 23. In some embodiments, the inner diameter of the conduit 11 of the anti-bird device 7 at the portion near the second connector 6 may be larger than the outer diameter of the second end cap 13 and its nut 23, so that the second connector 6 may be guided and received in this portion of the conduit 11.

Referring to fig. 4a, 4b and 4c, the jumper unit 2 includes a nut 21 fixed on the circumference of the first connector 4, and a spring 22 clamped between the nut 21 and the fixing sleeve 20. The first connector 4 together with the nut 21 and the spring 22 may be accommodated in the through hole 10 of the housing 3 and fixed in the through hole 10 by the fixing sleeve 20.

The sleeve-side connection 15 of the first end cap 12 can have a radially enlarged portion 16 radially inside its free end face, which can be adapted structurally to the free end of the fixing sleeve 20. Due to the tension of the guide tube 11, the sleeve-side connection 15 of the first end cap 12 can rest with its radially enlarged portion 16 against the fixing sleeve 20 of the cable 5. An adhesive may additionally be applied at the abutment to secure and seal the abutment. The other end portion of the fixing sleeve 20 may be inserted and fixed in the through hole 10 of the housing 3. In addition to the radially enlarged portion 16 design of the first end cap 12, other corresponding structures of the first end cap 12 and the fixing sleeve 20 may be provided to achieve abutment or the two may be locked together by means of separate locking means. As described above, since the outer diameter of the guide tube 11 of the metal bird repellent device 7 of the present invention can be designed to be small enough, for example, to be slightly larger than the diameter of the cable 5, the cable 5 is not bent outward at the portion near the housing 3 due to the cable 5 being pressed against each other at the housing side by the addition of the bird repellent device 7. This is clearly visible in fig. 4d, where the housing-side part of each cable 5 can still remain straight.

Instead of the abutting and adhesive connection of the first end cap 12 to the fixing sleeve 20 in the above described embodiment, fig. 4e shows the connection of the two by means of the clip member 30. The structure of the clip member 30 is shown in figure 4 f. The clip member 30 may be two-piece, i.e. comprising a first half 31 of a W-shape and a second half 32 of a W-shape. The free ends of the two lateral legs of the first half 31 may be provided with male snap-in portions 34 and the free ends of the two lateral legs of the second half 32 may be provided with corresponding female snap-in portions 35. The male snap-in part 34 and the female snap-in part 35 may be locked to each other. Each

half

31, 32 may comprise two U-shaped pieces, respectively. In the mounted state of the clip element 30, each U-shaped element receives and holds together a fixing sleeve 20 and a first end cap 12. At the same time, the middle legs of the two W-shaped

halves

31, 32 can also clamp and fix together a fixing sleeve 20 and a first end cap 12 in the middle.

The jumper unit 2 with the bird repelling device 7 installed in fig. 4a can be integrated into the bundled rf connector jumper assembly 1 of the present invention for use, or can be used separately.

Fig. 5a to 5c show the housing 3 of the invention in a perspective view and a sectional view, respectively. The housing 3 may be made of metal to perform the bird pecking prevention function. Furthermore, the metal housing 3 can be made of less material and at the same time have greater strength than a plastic housing. The housing 3 can therefore have recesses 17 or material savings in its circumferential direction in order to save material. The recesses 17 may be provided between the through holes 10.

The internal structure of a through-opening 10 in the housing 3 can be seen in fig. 5 c. The through-hole 10 comprises a first hole section 24 with a larger diameter and a second hole section 25 with a smaller diameter. Between the two hole sections 24, 25 a step 26 may be formed, which may be abutted by the nut 21 on the circumference of the first connector 4 (see fig. 6). The portion of the first bore section 24 near the step 26 may be provided with a surface structure 27 adapted to the nut 21, which surface structure 27 may prevent rotation of the nut 21.

The number of the through holes 10 of the housing 3 may be equal to the number of the jumper units 2. In the present embodiment, the housing 3 may have 5 through holes 10 for accommodating the first connectors 4 of the 5 jumper units 2, respectively. The number and arrangement of the through holes 10 in the housing 3 may vary according to specific needs. In the present embodiment, one through-hole 10 of the five through-holes 10 may be arranged at the center of the housing 3, and the remaining four through-holes 10 are arranged around the central through-hole 10. In other embodiments, the through holes 10 may be arranged in rows in the housing 3, such as in one row, in two rows, in more rows, in a circumferential arrangement, such as along the circumference of the housing 3, or in a honeycomb arrangement, as well as in other possible arrangements.

Fig. 6 shows an enlarged view of a partial cut-away of the connecting portion of the housing 3 and the first connector 4. It can be seen from fig. 6 that 3 first connectors 4 are located in 3 corresponding through holes 10 of the housing 3, respectively. The nut 21 can abut against the step 26 of the through-hole 10, thereby preventing the first connector 4 from moving axially to the right. The outer surface of the nut 21 and the surface structure 27 of the through hole 10 may cooperate so as to prevent the first connector 4 from rotating in the circumferential direction. As described above, the fixing sleeve 20 may be partially inserted into the through-hole 10 with the radially outer surface of the inserted portion being interference-fitted with the through-hole 10. The radially inner surface of the insertion portion of the fixing sleeve 20 may be clearance-fitted with the circumferential surface of the left end portion 28 of the first connector 4 so that the first connector 4 can move left and right. The fixing sleeve 20 may be provided with a step 29 towards the left end 28 of the first connector 4, and this step 29 is spaced from the left end 28 of the first connector 4 by a distance, so that the first connector 4 may be moved to the left, based on this distance and the elasticity of the spring 22, until the left end 28 of the first connector 4 abuts against the step 29 of the fixing sleeve 20. Thus, the first connector 4 may have partial axial adjustability in the housing 3.

The fixing of the first connector 4 in the housing 3 by means of the fixing sleeve 20 shown in fig. 6 is merely exemplary. In some embodiments, the first connector 4 and the housing 3 may be threaded. In some embodiments, the first connector 4 is locked into the housing 3 by means of an additional locking member.

The utility model discloses a radio frequency connector jumper wire subassembly 1 tied in a bundle lies in, when being favorable to installing a plurality of cables on the antenna and not reducing the cable performance, it still has good bird pecking prevention function. Furthermore, the axial flexibility and bendability of the metal conduit 11 of the bird guard 7 may improve the mounting flexibility and further facilitate the mounting process. The metal duct 11 may be unsealed in its circumferential direction so that condensed water entering the bird repelling apparatus 7 due to a temperature difference between day and night or rain can be discharged to the external environment at any time without damaging internal devices.

The jumper unit 2 of the present invention is characterized in that it has a good bird pecking prevention function. Thus, the jumper unit 2 may be used in the australian market with bird pecking protection requirements, either alone or in combination as a jumper assembly. Furthermore, the axial flexibility and bendability of the metal conduit 11 of the bird guard 7 may improve the mounting flexibility and further facilitate the mounting process. The metal duct 11 may be unsealed in its circumferential direction so that condensed water entering the bird repelling apparatus 7 due to a temperature difference between day and night or rain can be discharged to the external environment at any time without damaging internal devices.
