Description

Technical Field

[0001] This utility model relates to the field of dielectric withstand voltage testing technology for optoelectronic hybrid cable assemblies, specifically to a dielectric withstand voltage testing fixture for optoelectronic hybrid cable assemblies. Background Technology

[0002] With the development of technologies such as WiFi 6, hybrid optical and electrical cable components, which combine the advantages of optical cable's large transmission bandwidth and copper cable's ability to supply power, can be widely deployed in scenarios where local power supply is difficult and bandwidth demand is high, enabling flexible site selection and on-demand deployment, and have broad development potential and market.

[0003] Dielectric withstand voltage is one of the important electrical performance indicators of optical-electric hybrid cable assemblies. Using products with substandard dielectric withstand voltage may lead to short circuits that cause fires or regional network paralysis. The main purpose of dielectric withstand voltage testing is to check the product's ability to withstand working voltage or overvoltage, and thus verify whether the product's performance meets the standard requirements.

[0004] A search revealed that patent publication number CN219799652U discloses an auxiliary fixture for dielectric withstand voltage testing of insulation resistance. The fixture includes a waterproof and insulating test box. Two test clamps for holding external test leads are sealed to the side wall of the test box. The two test clamps are respectively a high-voltage end and a grounding end. Multiple adapter mechanisms are provided inside the test box; each adapter mechanism includes a high-voltage wire and a grounding wire installed within the test box. This invention places previously exposed conductive components inside a waterproof and insulating test box, achieving the testing requirements through internal electrical connections. This reduces the risk of accidental contact and leakage. Furthermore, the adapter mechanisms allow for the simultaneous installation of multiple connectors for connecting to external test leads on the outer surface of the test box, enabling batch testing and significantly improving testing efficiency.

[0005] The positive and negative terminals of existing optoelectronic hybrid cable assemblies are generally located on the front, side, or inside of the connector. However, the test fixtures of conventional dielectric withstand voltage testing equipment are generally clips or probes, which cannot quickly, effectively, and tightly connect to the electrical terminals of optoelectronic hybrid cable assemblies for testing. Therefore, a dielectric withstand voltage testing fixture for optoelectronic hybrid cable assemblies is designed. Utility Model Content

[0006] To address the shortcomings or deficiencies of existing dielectric withstand voltage testing fixtures for hybrid optoelectronic cable assemblies, this utility model aims to provide a dielectric withstand voltage testing fixture for hybrid optoelectronic cable assemblies. This fixture not only allows for quick connection to the electrical terminals of the hybrid optoelectronic cable assembly, effectively improving testing efficiency, but also prevents testing personnel from touching the high-voltage test head of the fixture during the testing process, protecting personal safety and improving overall safety.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] The optical-electric hybrid cable assembly dielectric withstand voltage test fixture provided by this utility model includes an insulating shell. From left to right, a first adapter, a third adapter, and a second adapter are arranged on the top of the insulating shell. The top of the first adapter, the third adapter, and the second adapter are respectively provided with a first metal contact, a third metal contact, and a second metal contact. A first groove and a second groove are respectively opened on both sides of the front wall of the insulating shell. A first terminal clamping fixture and a second terminal clamping fixture are respectively arranged in the first groove and the second groove.

[0009] Insulating L-shaped connecting blocks are provided on both sides of the rear end wall of the insulating shell. The insulating L-shaped connecting blocks are movably connected to the insulating protrusions through movable pins. The insulating protrusions are provided on one side of the outer wall of the insulating protective cover, and an insulating protective plate is installed on the other side of the outer wall of the insulating protective cover.

[0010] Preferably, a storage battery is disposed inside the insulating housing.

[0011] Preferably, a charging interface is provided at the center of the front end wall of the insulating housing.

[0012] Preferably, a light box, a main power indicator light, and a control switch button are arranged sequentially from front to back on one side of the outer wall of the insulating housing, and a first indicator light, a second indicator light, and a third indicator light are arranged sequentially from front to back on the top of the light box.

[0013] Preferably, the positive and negative metal terminals on the first adapter are connected to the first terminal clamp and the second terminal clamp respectively via wires.

[0014] Preferably, the positive and negative metal terminals on the second adapter are connected to the first terminal clamp and the second terminal clamp respectively via wires.

[0015] Preferably, the positive and negative metal terminals on the third adapter are connected to the first terminal clamp and the second terminal clamp respectively via wires.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. In this utility model, through a series of coordinated structural arrangements, when the operator performs dielectric withstand voltage testing on the optoelectronic hybrid cable assembly, the operator first connects the positive and negative terminals of the dielectric withstand voltage testing equipment to the first terminal clamp and the second terminal clamp, respectively. After starting the fixture by controlling the switch button, the operator selects the corresponding adapter according to the connector type of the optoelectronic hybrid cable assembly to be tested, and then confirms the validity of the corresponding adapter link. When confirming the validity of the link of the adapter corresponding to the optoelectronic hybrid cable assembly to be tested, the operator connects the prefabricated connector to the corresponding adapter. If the main power indicator and the corresponding indicator light of the adapter are lit, it indicates that the link of the adapter is normal and can be tested. The operator inserts the connector of the optoelectronic hybrid cable assembly into the corresponding adapter on the fixture and presses the test button of the dielectric withstand voltage testing equipment to perform the test. Thus, this utility model can not only quickly connect to the electrical terminals of the optoelectronic hybrid cable assembly, effectively improving the testing efficiency, but also prevents the testing personnel from touching the high-voltage test head of the fixture during the testing process, protecting personal safety and improving safety.

[0018] 2. In this utility model, through the combined arrangement of structures such as the insulating protective cover and the insulating protective plate, the insulating protective cover can protect the first adapter, the second adapter, and the third adapter, preventing external dust or liquid from adhering to the first adapter, the second adapter, and the third adapter, thus reducing their service life. The insulating protective plate can protect the first terminal clamp and the second terminal clamp, preventing external dust or liquid from adhering to the first terminal clamp and the second terminal clamp, thus reducing their service life.

[0032] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, 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 invention pertains.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] like Figure 1-4As shown, the dielectric withstand voltage test fixture for the optoelectronic hybrid cable assembly includes an insulating housing 100. From left to right, a first adapter 300, a third adapter 500, and a second adapter 400 are arranged on the top of the insulating housing 100. The tops of the first adapter 300, the third adapter 500, and the second adapter 400 are respectively provided with a first metal contact 310, a third metal contact 510, and a second metal contact 410. The first adapter 300, the third adapter 500, and the second adapter 400 are three different types of adapters. The three different types of adapters can be matched with the connector types of different optoelectronic hybrid cable assemblies under test, which facilitates the staff to test different types of optoelectronic hybrid cable assemblies under test. The front wall of the insulating housing 100 is provided with a first groove 140 and a second groove 150 on both sides. The first groove 140 and the second groove 150 are respectively provided with a first terminal clamping fixture 170 and a second terminal clamping fixture 180.

[0035] Insulating L-shaped connecting blocks 190 are provided on both sides of the rear end wall of the insulating housing 100. The insulating L-shaped connecting blocks 190 are movably connected to the insulating protrusions 220 via movable pins. The insulating protrusions 220 are provided on one outer wall of the insulating protective cover 200. The insulating protective cover 200 can protect the first adapter 300, the second adapter 400, and the third adapter 500, preventing external dust or liquid from adhering to the first adapter 300, the second adapter 400, and the third adapter 500, which would reduce the service life of the first adapter 300, the second adapter 400, and the third adapter 500. In the event of this situation, because the insulating L-shaped connecting block 190 is movably connected to the insulating protrusion 220 through the movable pin, the operator can rotate one end of the insulating protective cover 200. An insulating protective plate 210 is installed on the outer wall of the other side of the insulating protective cover 200. The insulating protective plate 210 can protect the first terminal clamping fixture 170 and the second terminal clamping fixture 180, and prevent external dust or liquid from adhering to the first terminal clamping fixture 170 and the second terminal clamping fixture 180, which would reduce the service life of the first terminal clamping fixture 170 and the second terminal clamping fixture 180.

[0036] An internal storage battery 600 is installed in the insulating housing 100, which can provide power to this tooling.

[0037] A charging interface 160 is provided at the center of the front wall of the insulating housing 100, allowing the operator to charge the battery 600.

[0038] The outer wall of one side of the insulating housing 100 is provided with a light box 130, a main power indicator light 120 and a control switch button 110 in sequence from front to back. The top of the light box 130 is provided with a first indicator light 131, a second indicator light 132 and a third indicator light 133 in sequence from front to back. The first indicator light 131, the second indicator light 132 and the third indicator light 133 correspond to the first adapter 300, the second adapter 400 and the third adapter 500 respectively. When the link of the first adapter 300, the second adapter 400 or the third adapter 500 is valid, the corresponding first indicator light 131, the second indicator light 132 or the third indicator light 133 will light up.

[0039] The positive and negative metal terminals on the first adapter 300 are connected to the first terminal clamping fixture 170 and the second terminal clamping fixture 180 respectively via wires.

[0040] The positive and negative metal terminals on the second adapter 400 are connected to the first terminal clamping fixture 170 and the second terminal clamping fixture 180 respectively via wires.

[0041] The positive and negative metal terminals on the third adapter 500 are connected to the first terminal clamping fixture 170 and the second terminal clamping fixture 180 respectively via wires.

[0042] Working Principle: When performing dielectric withstand voltage testing on the optoelectronic hybrid cable assembly, the operator first connects the positive and negative terminals of the dielectric withstand voltage testing equipment to the first terminal clamp 170 and the second terminal clamp 180, respectively. After starting the fixture via the control switch button 110, the operator selects the corresponding adapter according to the connector type of the optoelectronic hybrid cable assembly under test, and then confirms the validity of the corresponding adapter link. When confirming the validity of the link of the adapter corresponding to the optoelectronic hybrid cable assembly under test, the operator connects the prefabricated connector to the corresponding adapter. If the main power indicator 120 and the corresponding indicator light of the adapter are lit, it indicates that the adapter link is normal and can be tested. The operator inserts the connector of the optoelectronic hybrid cable assembly into the corresponding adapter on the fixture and presses the test button of the dielectric withstand voltage testing equipment to perform the test. Thus, this utility model can not only quickly connect to the electrical terminals of the optoelectronic hybrid cable assembly, effectively improving the testing efficiency, but also prevents the testing personnel from touching the high-voltage test head of the fixture during the testing process, protecting personal safety and improving safety.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention.
