Description

Technical Field

[0001] This disclosure relates to the technical field of signal switching equipment, and in particular to a plug-in structure for signal towers and an outdoor male and female wiring assembly. Background Technology

[0002] Signal towers are typically built outdoors, which necessitates that the male and female connectors installed on them possess superior weather resistance. Currently, most manufacturers typically use male and female connectors, such as those described in Chinese patent document CN104409915A, to withstand rain. However, signal towers are usually quite high, exposing the male and female connectors to more ultraviolet radiation and the tower's own radiation. This makes the waterproof structure of the male and female connectors more susceptible to corrosion under the influence of ultraviolet rays and radiation, thus significantly shortening their waterproof lifespan. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a plug-in structure for signal towers that can slow down corrosion rates, is waterproof, and has a longer service life, as well as an outdoor male and female wiring assembly.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A plug-in structure for a signal tower includes a male plug body and a female plug body arranged opposite to each other, wherein the pins of the male plug body are electrically connected to the terminals of the female plug body;

[0006] The plug-in structure for the signal tower also includes a metal protective sleeve, a water-blocking sleeve, and a covering body;

[0007] The covering body encloses the terminals of the female connector body; the water-retaining sleeve is sealed and fitted around the outer periphery of the male connector body and extends to form a water-retaining wall; the water-retaining wall surrounds the pins of the male connector body and is sealed and fitted around a portion of the outer periphery of the covering body to form a waterproof assembly; the pins of the male connector body penetrate the covering body and contact the terminals of the female connector body to make the male connector body and the female connector body electrically connected to each other; the metal protective sleeve is fitted over the outside of the waterproof assembly.

[0008] In some embodiments, the metal protective sleeve includes a metal sleeve and a hollow metal base, the metal sleeve being fitted over the water-blocking shell; the covering body and the female insert body are both embedded in the hollow portion of the hollow metal base, and the portion of the metal sleeve and the corresponding portion of the metal base are nested together.

[0009] In some embodiments, the inner wall of the metal sleeve is rotatably connected to the outer peripheral wall of the water-blocking sleeve; a portion of the metal sleeve extends toward the hollow metal seat and forms a first threaded structure; a second threaded structure is formed on the corresponding portion of the hollow metal seat, and the first threaded structure is threadedly screwed onto the second threaded structure.

[0010] In some embodiments, a portion of the metal sleeve is fitted around the outer periphery of a corresponding portion of the hollow metal seat; or,

[0011] The corresponding part of the hollow metal seat is fitted onto the outer periphery of the part of the metal sleeve.

[0012] In some embodiments, the plug-in structure for the signal tower further includes a connected hanging chain and a protective cover; the protective cover is designed to be detachably fitted to the hollow metal base when the male plug body is separated from the female plug body, and to cover the enclosure.

[0013] In some embodiments, a concave groove is formed on the outer peripheral wall of the water-blocking sleeve, and a retaining rib is protruding from the inner wall of the metal sleeve into the concave groove, the retaining rib being movably disposed within the concave groove.

[0014] In some embodiments, the metal protective sleeve is a zinc alloy protective sleeve or a nickel alloy protective sleeve.

[0015] In some embodiments, the water-retaining sleeve includes a threaded plastic sleeve and a metal sleeve, the metal sleeve being sealed around the male connector body, and the water-retaining wall being formed on the metal sleeve; the plastic sleeve surrounds the male connector body at one end away from the cover.

[0016] In some embodiments, the male connector body has a plurality of pins, and adjacent pins are separated by a first insulating sheet at the ends away from the female connector body; and / or,

[0017] The female connector has multiple terminals, and the ends of adjacent terminals that are away from the male connector are separated by a second insulating sheet.

[0018] An outdoor male-female wiring assembly includes a plug-in structure for signal towers according to any of the above embodiments.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] The aforementioned plug-in structure for signal towers reduces the exposure of the female plug's terminals by covering them with an enclosure. Furthermore, the water-retaining sleeve, sealed around the male plug, further reduces its exposure. A water-retaining wall, extending from the sleeve, surrounds the male plug's pins and seals the outer periphery of the enclosure, forming a waterproof assembly. This effectively reduces direct contact between external moisture and the male plug's pins and the female plug's terminals. A metal protective sheath then reflects or absorbs ultraviolet radiation, slowing the corrosion rate of the entire waterproof assembly and ultimately extending the waterproof service life of the signal tower plug-in structure.

[0036] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0040] Please see Figure 1 and Figure 2One embodiment of the plug-in structure for a signal tower includes a male plug body 100, a female plug body 200, a metal protective sleeve 300, a water-retaining sleeve 400, and a covering body 500 arranged opposite each other. The pins 110 of the male plug body 100 are electrically connected to the terminals 210 of the female plug body 200. The covering body 500 covers the terminals 210 of the female plug body 200. The water-retaining sleeve 400 is sealed and fitted around the outer periphery of the male plug body 100 and extends to form a water-retaining wall 4210. The water-retaining wall 4210 surrounds the pins 110 of the male plug body 100 and is sealed and fitted around a portion of the outer periphery of the covering body 500 to form a waterproof assembly. The pins 110 of the male plug body 100 penetrate the covering body 500 and contact the terminals 210 of the female plug body 200, so that the male plug body 100 and the female plug body 200 are electrically connected to each other. The metal protective sleeve 300 is fitted over the outside of the waterproof assembly.

[0041] It is understandable that because the cover 500 covers the terminals 210 of the female connector body 200, the exposure of the terminals 210 of the female connector body 200 can be reduced by the cover 500, and the exposure of the male connector body 100 can be reduced by the water-retaining sleeve 400 sealingly fitting around the outer periphery of the male connector body 100. At this time, the water-retaining wall 4210 formed by the extension of the water-retaining sleeve 400 surrounds the pins 110 of the male connector body 100 and is sealed around part of the outer periphery of the cover 500, so that the water-retaining sleeve 400 and the cover 500 form a waterproof assembly, which can effectively reduce the direct contact of external moisture with the pins 110 of the male connector body 100 and the terminals 210 of the female connector body 200. Then, the metal protective sleeve 300 is fitted on the outside of the waterproof assembly, so that the metal protective sleeve 300 reflects ultraviolet rays or absorbs radiation, thereby slowing down the corrosion rate of the entire waterproof assembly and ultimately extending the service life of the waterproof connector structure for signal towers.

[0042] Please see Figure 2 In some embodiments, the metal protective sleeve 300 includes a metal sleeve 310 and a hollow metal base 320. The metal sleeve 310 is fitted over the water-retaining shell 400. The covering body 500 and the female insert body 200 are both embedded in the hollow portion of the hollow metal base 320, with portions of the metal sleeve 310 and corresponding portions of the metal base nested together. It can be understood that because the metal sleeve 310 is fitted over the water-retaining shell 400, it can protect the water-retaining shell 400 by reflecting ultraviolet rays or absorbing radiation. Similarly, because the covering body 500 and the female insert body 200 are both embedded in the hollow portion of the hollow metal base 320, the hollow metal base 320 can protect the covering body 500 and the female insert body 200 by reflecting ultraviolet rays or absorbing radiation. The nested arrangement of portions of the metal sleeve 310 and corresponding portions of the metal base creates a tightly structured metal protective sleeve 300, enhancing the protective capability of the waterproof assembly.

[0043] Please see Figure 2 In some embodiments, the inner wall of the metal sleeve 310 is rotatably connected to the outer peripheral wall of the water-retaining sleeve 400; a portion of the metal sleeve 310 extends toward the hollow metal seat 320 and forms a first threaded structure 3110; a second threaded structure 3210 is formed on the corresponding portion of the hollow metal seat 320, and the first threaded structure 3110 is threadedly screwed onto the second threaded structure 3210. It can be understood that because the inner wall of the metal sleeve 310 is rotatably connected to the outer peripheral wall of the water-retaining sleeve 400, rotating the metal sleeve 310 allows the first threaded structure 3110 formed on a portion of the metal sleeve 310 to be threadedly screwed onto the second threaded structure 3210 formed on the corresponding portion of the hollow metal seat 320, thereby achieving quick assembly and disassembly between the metal sleeve 310 and the hollow metal seat 320.

[0044] Please see Figure 1 and Figure 2 In this embodiment, a portion of the metal sleeve 310 is fitted onto the outer periphery of the corresponding portion of the hollow metal base 320. It can be understood that the first thread structure 3110 is an internal thread structure, and the second thread structure 3210 is an external thread structure. After the first thread structure 3110 is threaded onto the second thread structure 3210, a portion of the metal sleeve 310 can be securely fitted onto the outer periphery of the corresponding portion of the hollow metal base 320. Specifically, a guide groove 3201 is provided on the inner peripheral wall of the corresponding portion of the hollow metal base 320, and a guide rib 4211 protrudes from the outer wall of the water-blocking wall 4210. The guide rib 4211 is used for sliding engagement with the guide groove 3201, thereby guiding the operator to correctly assemble the male connector body 100 and the female connector body 200, achieving a foolproof effect.

[0045] In some embodiments, the corresponding portion of the hollow metal seat is fitted onto the outer periphery of the portion of the metal sleeve. It is understood that the first threaded structure is an external threaded structure, and the second threaded structure is an internal threaded structure. After the first threaded structure is screwed onto the second threaded structure, the corresponding portion of the hollow metal seat can be securely fitted onto the outer periphery of the portion of the metal sleeve.

[0046] Please see Figure 1In some embodiments, the plug-in structure for the signal tower further includes a connecting chain 600 and a protective cover 700. The protective cover 700 is detachably fitted onto the hollow metal base 320 when the male plug body 100 is separated from the female plug body 200, and covers the enclosure 500. It is understood that the chain 600 can be installed on the hollow metal base 320, and when the male plug body 100 is separated from the female plug body 200, the protective cover 700 can be detachably fitted onto the hollow metal base 320, thereby covering the enclosure 500 by blocking the opening of the hollow metal base 320, thus providing temporary protection for the terminals 210 of the female plug body 200. Specifically, the protective cover 700 is threaded onto the hollow metal base 320.

[0047] Please see Figure 2 In some embodiments, a concave groove 401 is formed on the outer peripheral wall of the water-blocking sleeve 400, and a retaining rib 3120 protrudes from the inner wall of the metal sleeve 310 into the concave groove 401. The retaining rib 3120 is movably disposed within the concave groove 401. It can be understood that because the retaining rib 3120 formed on the inner wall of the metal sleeve 310 is movably disposed within the concave groove 401, it can interfere with the groove wall of the concave groove 401 to prevent the metal sleeve 310 from detaching from the water-blocking sleeve 400. Furthermore, when the metal sleeve 310 is twisted, the retaining rib 3120 remains movable within the concave groove 401, allowing the metal sleeve 310 to rotate smoothly.

[0048] In some embodiments, the metal protective sheath 300 is a zinc alloy protective sheath. It is understood that zinc alloy protective sheaths have better corrosion resistance and can absorb radiation more efficiently.

[0049] In some embodiments, the metal protective sheath 300 is a nickel alloy protective sheath. It is understood that nickel alloy protective sheaths have better corrosion resistance and can absorb radiation more efficiently.

[0050] Please see Figure 2In some embodiments, the water-retaining sleeve 400 includes a threaded plastic sleeve 410 and a metal sleeve 420. The metal sleeve 420 is sealed around the male connector body 100, and a water-retaining wall 4210 is formed on the metal sleeve 420. The plastic sleeve 410 surrounds the male connector body 100 at the end away from the cover body 500. It is understood that by sealing the male connector body 100 with the metal sleeve 420, the male connector body 100 can be waterproofed or have radiation absorbed through the metal sleeve 420. Furthermore, since the plastic sleeve 410 surrounds the male connector body 100 at the end away from the cover body 500, the end of the male connector body 100 away from the cover body 500 can be waterproofed through the plastic sleeve 410. The threaded connection of the plastic sleeve 410 to the metal sleeve 420 facilitates disassembly.

[0051] Please see Figure 2 In some embodiments, the male connector body 100 has multiple pins 110, and adjacent pins 110 are separated from the ends of the female connector body 200 by a first insulating sheet 810. It is understood that since the power of the signal tower connector structure is relatively high during use, separating adjacent pins 110 from the ends of the female connector body 200 by the first insulating sheet 810—that is, the first insulating sheet 810 being located between the ends of two adjacent pins 110 from the female connector body 200—can reduce the electric arc generated between adjacent pins 110, thereby ensuring safety during use. Specifically, there are multiple first insulating sheets 810; these multiple first insulating sheets 810 are integrally formed to form a first insulating frame 800.

[0052] Please see Figure 2 and Figure 3 In some embodiments, the female connector body 200 has multiple terminals 210, and the ends of adjacent terminals 210 furthest from the male connector body 100 are separated by a second insulating sheet 910. It is understood that since the power of the plug-in structure for signal towers is relatively high during use, separating the ends of adjacent terminals 210 furthest from the male connector body 100 by the second insulating sheet 910—that is, the second insulating sheet 910 being located between the ends of two adjacent terminals 210 furthest from the male connector body 100—can reduce the arc generated between adjacent terminals 210, thereby ensuring safety during use. Specifically, there are multiple second insulating sheets 910; these multiple second insulating sheets 910 are integrally formed to form a second insulating frame 900.

[0053] Please see Figure 1 and Figure 2This disclosure also provides an outdoor male-female wiring assembly, including the plug-in structure for signal towers of any of the above embodiments. It is understood that by applying the plug-in structure for signal towers of this disclosure to the outdoor male-female wiring assembly, since the cover 500 covers the terminals 210 of the female plug body 200, the exposure of the terminals 210 of the female plug body 200 can be reduced by the cover 500, and the exposure of the male plug body 100 can be reduced by the water-blocking sleeve 400 sealingly fitting around the outer periphery of the male plug body 100. At this time, the water-blocking wall 4210 formed by the extension of the water-blocking sleeve 400 surrounds the pin 110 of the male connector body 100 and is sealed and fitted on part of the outer periphery of the covering body 500. This allows the water-blocking sleeve 400 and the covering body 500 to form a waterproof assembly, thereby effectively reducing the direct contact of external moisture with the pin 110 of the male connector body 100 and the terminal 210 of the female connector body 200. Then, the metal protective sleeve 300 is fitted on the outside of the waterproof assembly, thereby reflecting ultraviolet rays or absorbing radiation, thus slowing down the corrosion rate of the entire waterproof assembly and ultimately extending the service life of the waterproof connector structure for signal towers.

[0054] Compared with the prior art, this disclosure has at least the following advantages:

[0055] In the aforementioned plug-in structure for signal towers, the covering body 500 covers the terminals 210 of the female plug body 200, reducing the exposure of the terminals 210. Furthermore, the water-retaining sleeve 400, sealed around the male plug body 100, further reduces the exposure of the male plug body 100. The water-retaining wall 4210, formed by the extension of the water-retaining sleeve 400, surrounds the pins 110 of the male plug body 100 and is sealed around a portion of the outer periphery of the covering body 500. This allows the water-retaining sleeve 400 and the covering body 500 to form a waterproof assembly, effectively reducing direct contact between external moisture and the pins 110 of the male plug body 100 and the terminals 210 of the female plug body 200. A metal protective sleeve 300 is then fitted over the waterproof assembly, reflecting ultraviolet rays or absorbing radiation, thus slowing down the corrosion rate of the entire waterproof assembly and ultimately extending the waterproof service life of the plug-in structure for signal towers.

[0056] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
