Description

Technical Field

[0001] This utility model relates to the technical field of communication network testing devices, and in particular to a communication network testing device. Background Technology

[0002] Existing communication network test probes are mired in a severe predicament of being "unable to prevent dust, slow to connect, and unstable to use": their weak manual dust prevention mechanisms (such as easily lost covers and inferior sealing rings) are practically useless in harsh high-frequency tests, allowing dust and moisture to penetrate unimpeded, causing signal distortion, test failures, and frequent misdiagnosis. Furthermore, they severely corrode precision contacts, drastically shorten the lifespan of expensive equipment, and create a fatal hidden danger of critical business interruption. At the same time, the lack of precision guidance and buffer design makes plugging and unplugging like "blind operation," with repeated misalignment, difficulty in plugging and unplugging, and interface damage becoming commonplace, consuming a great deal of manpower and time, and dragging down project progress exponentially in large-scale operations and maintenance. The mechanical separation of dust prevention and connection functions forces operators into a redundant "open cover-plug-close cover" cycle, completely stifling efficiency. In addition, the instability of moving parts introduces test errors, and the lack of modularity leads to high maintenance costs and long cycles, which together constitute a systemic bottleneck restricting the efficiency, reliability, and cost control of network construction and maintenance. These pain points are particularly acute in modern high-speed, high-density, and high-reliability communication networks, reducing the lifespan of communication network testing equipment and installation and connection efficiency.

[0003] Therefore, this application provides a communication network testing apparatus to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a communication network testing device.

[0005] The technical problem to be solved by this utility model is to provide a communication network testing device to solve the problems of existing communication network testing devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A communication network testing device includes a connector and multiple test display devices, wherein multiple connection ports of the connector are connected to the multiple test display devices via a connection component;

[0008] The connector includes, from the inside out, a plug-in detection head, a limiting outer ring, and a dustproof component. The limiting outer ring and the dustproof component are both surrounding the center of the plug-in detection head and sleeved on the outer surface of the plug-in detection head. The ends of the plug-in detection head and the limiting outer ring away from the connecting assembly are flush with each other. The inner surface of the dustproof component is in contact with the flush end surface of the plug-in detection head and the limiting outer ring.

[0009] The outer ring of the limiting device has a locking groove for engaging the dustproof component.

[0010] Preferably, a return spring is clamped between the insertion detection head and the limiting outer ring. One end of the return spring is in contact with the outer surface of the insertion detection head, and the other end of the return spring is in contact with the inner side wall of the limiting outer ring. A limiting ring is clamped and sleeved at the end of both the insertion detection head and the limiting outer ring away from the connecting assembly. The outer surface of the limiting ring is in close contact with the hinge joint between the insertion detection head and the limiting outer ring.

[0011] Preferably, a plurality of limiting balls are provided in a ring shape at equal intervals between the insertion detection head and the limiting outer ring, and the plurality of limiting balls are slidably installed between the insertion detection head and the limiting outer ring.

[0012] Preferably, the dustproof component includes a locking ring and a plurality of dustproof flaps, one end of each of the plurality of dustproof flaps being integrally connected to one side surface of the locking ring, and the plurality of dustproof flaps being distributed in a ring at equal intervals, and the locking ring being installed inside the locking groove.

[0013] Preferably, the outer surface of the limiting outer ring is provided with a plurality of sliding blocks at equal intervals in a ring shape, and the outer surface of the limiting outer ring is fitted with an opening and closing ring.

[0014] Preferably, the dustproof flap has a sliding groove inside for the sliding block to slide, and the inner surface of the dustproof flap has a limiting groove for the opening and closing ring to be limited.

[0015] Preferably, the connection component includes a port connector and a connecting cable. The port connector is sleeved on the interface end of the test display device, and one end of the connecting cable is installed inside the port connector, while the other end is installed inside the plug-in detection head.

[0016] In the above solution, when the probe is inserted, its insertion action is linked by a built-in mechanism, which can automatically and smoothly open the dustproof flap radially without additional manual operation. The annularly distributed limit balls provide precise radial guidance, and the reset spring provides buffering and smooth feel. Combined with the flat insertion guide surface, it ensures that the probe can be quickly, accurately, and in one go into the port under test. When pulled out, the dustproof flap is automatically reset and closed instantly under the action of the spring, realizing the efficient operation of "plug and test, pull and protect", which greatly improves the convenience and work efficiency of on-site testing.

[0017] The above solution employs an innovative dynamic self-closing dustproof flap design with its inner end face tightly fitting the probe end face, an embedded sealing ring, and a sealing ring end face, forming a triple-layer synergistic protection mechanism. After the probe is removed from the device under test, the dustproof flap can automatically and tightly close instantly under the action of the return spring. Combined with the robust locking and end face sealing, it effectively prevents dust, oil, and other contaminants from intruding into the core detection area and connection port, providing comprehensive and reliable active protection for sensitive components when not in use, significantly extending the probe's service life and ensuring testing accuracy.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a communication network testing device, which includes a connector 1 and multiple test display devices 2. The multiple connection ports of the connector 1 are connected to the multiple test display devices 2 through a connection component 3.

[0028] The connector 1 includes, from the inside out, a plug-in detection head 11, a limiting outer ring 12, and a dustproof component 13. The limiting outer ring 12 and the dustproof component 13 are both surrounding the center of the plug-in detection head 11 and fitted onto its outer surface. The plug-in detection head 11 and the limiting outer ring 12 are flush with the end away from the connecting component 3. The inner surface of the dustproof component 13 is in contact with the flush end surface of the plug-in detection head 11 and the limiting outer ring 12. This design of the connector 1 not only ensures the stability of the plug-in but also effectively prevents dust and other foreign objects from entering the interior of the connector 1 through the dustproof component 13, thus extending the service life of the device.

[0029] It should be noted that the connection component 3 includes a port connector 31 and a connecting cable 32. The port connector 31 is fitted onto the interface end of the test display device 2. One end of the connecting cable 32 is installed inside the port connector 31, and the other end is installed inside the plug-in detection head 11. The configuration of the connection component 3 can ensure stable and reliable signal transmission between the test display device 2 and the connector 1. The port connector 31 can adapt to different interface types of the test display device 2, enhancing the versatility of the device.

[0030] The outer ring 12 of the limiting ring has an engagement groove 19 for engaging the dustproof component 13;

[0031] It should be noted that the locking groove 19 enables the dustproof component 13 to be stably installed on the limiting outer ring 12, preventing the dustproof component 13 from shifting or falling off during use, thereby better fulfilling its dustproof function.

[0032] A reset spring 15 is clamped between the insertion detection head 11 and the limiting outer ring 12. One end of the reset spring 15 is in contact with the outer surface of the insertion detection head 11, and the other end of the reset spring 15 is in contact with the inner side wall of the limiting outer ring 12. A limiting ring 16 is clamped and sleeved at the end of both the insertion detection head 11 and the limiting outer ring 12 away from the connecting component 3. The outer surface of the limiting ring 16 is in close contact with the hinge joint between the insertion detection head 11 and the limiting outer ring 12.

[0033] It should be noted that the design of the reset spring 15 can provide reset power after the insertion detection head 11 is retracted under force, ensuring the flexibility and stability of the connector 1 during insertion and removal. The limiting ring 16 further restricts the position of the insertion detection head 11 and the limiting outer ring 12 to prevent them from moving excessively and causing structural damage.

[0034] Multiple limiting balls 14 are provided in an annular shape at equal intervals between the insertion detection head 11 and the limiting outer ring 12. The multiple limiting balls 14 are slidably installed between the insertion detection head 11 and the limiting outer ring 12.

[0035] It should be noted that the setting of the limiting ball 14 can provide radial support and guidance for the insertion detection head 11 during the insertion process, ensuring the accuracy of the insertion and preventing skewing, and at the same time, it can also enhance the structural strength of the connector 1 to a certain extent.

[0036] The dustproof component 13 includes a locking ring 133 and multiple dustproof petals 131. One end of each of the multiple dustproof petals 131 is integrally connected to one side surface of the locking ring 133, and the multiple dustproof petals 131 are distributed in a ring shape at equal intervals. The locking ring 133 is installed inside the locking groove 19.

[0037] It should be noted that the dustproof component 13 has a clever structural design, with multiple dustproof flaps 131 that can open and close flexibly during insertion and removal, effectively blocking dust without affecting the insertion operation.

[0038] The outer surface of the limiting outer ring 12 is provided with a plurality of sliding blocks 18 at equal intervals in a ring shape, and the outer surface of the limiting outer ring 12 is fitted with an opening and closing ring 17.

[0039] The dustproof flap 131 has a sliding groove 134 inside for the sliding block 18 to slide, and a limiting groove 132 is provided on the inner surface of the dustproof flap 131 for the opening and closing ring 17 to be limited.

[0040] It should be noted that the sliding groove 134 and the limiting groove 132 enable the sliding block 18 and the opening and closing ring 17 to stably cooperate with the dustproof flap 131, ensuring that the opening and closing action of the dustproof flap 131 is accurate.

[0041] The working principle provided by this utility model is as follows:

[0042] When the probe is inserted into the port under test (connection and automatic flap opening), the insertion detection head 11 is compressed and retracted at the moment of insertion, which slides the limiting ball 14 along the ring track to provide precise radial guidance and prevent skew. The reset spring 15 is compressed to absorb the impact force. The insertion detection head 11 and the limiting outer ring 12 move backward as a whole. The sliding block 18 on the surface of the limiting outer ring 12 moves in the inclined sliding groove 134 inside the dustproof flap 131, pushing the multiple dustproof flaps 131 to open radially outward, making room for the insertion channel. The insertion detection head 11 contacts the port under test without obstruction and establishes a communication connection.

[0043] When the port under test is pulled out (disconnection and instantaneous blocking), at the moment of pulling out, the reset spring 15 releases its stored energy, which pushes the plug-in detection head 11 / limiting outer ring 12 forward to reset. The sliding block 18 of the limiting outer ring 12 slides in the opposite direction in the sliding groove 134 of the dustproof petal 131, pulling multiple dustproof petals 131 to converge and close towards the center. The inner end face of the dustproof petal 131 is tightly attached to the flush end face of the plug-in detection head 11 and the limiting outer ring 12.

[0044] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
