Description
Technical Field
[0001] This utility model relates to the field of power testing technology, and in particular to a high-low voltage coupling testing device. Background Technology
[0002] In actual testing, due to the complex environment of the testing site, there may be personnel movement, equipment vibration, etc. The existing test cable connection method may not be stable enough. Relying only on simple plug-in connection, there is a lack of effective locking or fastening measures. This makes it easy for the test cable to fall out of the test cable slot when subjected to external force pulling or slight vibration, thereby interrupting the test process. This not only affects the test efficiency, but may also cause the loss of collected data, requiring retesting and wasting time and resources. The existing protective structure may not provide sufficient protection for the corners and other parts of the equipment, which can easily cause problems such as shell deformation and loosening of internal components, affecting the normal service life of the equipment and the test accuracy. Therefore, we have launched a high and low voltage coupling test device. Utility Model Content
[0003] The main purpose of this invention is to provide a high-low voltage coupling test device that can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A high-low voltage coupling test device includes an outer casing. Support feet are fixedly connected to the four lower corners of the outer casing. A cover is hinged to the upper rear part of the outer casing. Two slots are opened on both the left and right walls of the outer casing. A test device body is snapped into the outer casing. Protective devices are fixedly connected to the left and right ends of the test device body. Two control plates are fixedly connected to the upper left part of the test device body. A display panel, several test wiring slots, two sliding grooves, and a fixing device are respectively provided on the upper right part of the test device body. The display panel is located in front of the several test wiring slots, and the several test wiring slots are located directly below the fixing device.
[0006] The protective device includes two protective rubber plates. The lower front and lower rear ends of the two protective rubber plates are fixedly connected to two base plates. The lower left and lower right ends of the two base plates are fixedly connected to pads. The left front and left rear ends of the left protective rubber plate are fixedly connected to locking strips, and the right front and right rear ends of the right protective rubber plate are fixedly connected to locking strips. The upper ends of the two protective rubber plates are fixedly connected to handles. The two protective rubber plates are respectively fixedly connected to the left and right sides of the main body of the debugging equipment.
[0007] Preferably, the fixing device includes a rear fixing plate, with a No. 1 connecting block fixedly connected to the upper left and upper right parts of the rear fixing plate, and a short screw fixedly connected to the front end of each of the two No. 1 connecting blocks. The front end of the rear fixing plate has several rear wire-locking grooves, and each of the several rear wire-locking grooves is provided with an anti-slip layer. A No. 1 slider is fixedly connected to the lower left and lower right parts of the rear fixing plate. A connecting component is movably connected to the middle of the outer surface of the two short screws, and a fixing bolt is threaded to the front of the outer surface of each of the two short screws. The rear fixing plate is located at the upper right part of the main body of the debugging equipment.
[0008] By adopting the above technical solution, the No. 1 connecting block and the short screw are used to connect the front fixing plate to achieve the clamping and fixing of the cable.
[0009] Preferably, the connecting assembly includes a front fixing plate, with a second slider fixedly connected to the lower left and lower right ends of the front fixing plate, a plurality of front locking grooves opened at the rear end of the front fixing plate, and a second connecting block fixedly connected to the upper left and upper right ends of the front fixing plate, and the front fixing plate is located in front of the rear fixing plate.
[0010] By adopting the above technical solution, the second slider cooperates with the slide groove, allowing the front fixing plate to move flexibly and making it easy to adjust the distance between it and the rear fixing plate to accommodate cables of different diameters and positions.
[0011] Preferably, the structure of the rear fixing plate is the same as that of the front fixing plate and they are symmetrically distributed front and back.
[0012] By adopting the above technical solution, which features identical and symmetrical structures, the pressure applied by the front and rear fixing plates when fixing the cables is uniform and consistent, thus avoiding cable instability or damage due to uneven force.
[0013] Preferably, the two sliders are slidably connected in the groove.
[0014] By adopting the above technical solution, the cooperation between the first slider and the slide groove enhances the overall stability of the fixing device, preventing shaking or displacement during adjustment and ensuring the reliability of the fixing operation.
[0015] Preferably, the positional dimensions of the two card strips on the left correspond one-to-one with the positional dimensions of the two card slots on the left, and the positional dimensions of the two card strips on the right correspond one-to-one with the positional dimensions of the two card slots on the right.
[0016] By adopting the above technical solution, the protective device can be accurately snapped into the outer casing. The installation process is simple and convenient. Just align the clip with the slot and insert it. The tight snap-fit ensures that the protective device and the main body of the debugging equipment are firmly fixed in the outer casing, preventing displacement and shaking during equipment handling, transportation and daily use, and effectively protecting the main body of the debugging equipment.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. In this utility model, the high and low voltage coupling test equipment is equipped with a fixing device. The fixing device uses a rear fixing plate, a front fixing plate, and short screws and fixing bolts in between to firmly fix the test cable between the front and rear cable clamping slots. The anti-slip layer inside the cable clamping slot increases the friction and prevents the cable from loosening and falling off due to external pulling or equipment vibration. This effectively avoids test interruptions caused by the test cable falling off, reduces the time and resources wasted in retesting, greatly improves test efficiency, and ensures the integrity and continuity of test data.
[0019] 2. In this utility model, the protective device consists of a protective rubber plate, a base plate, pads, and locking strips. The protective rubber plate utilizes its own elasticity and cushioning performance to reduce the impact of external collisions on the main body of the equipment on the left and right sides. The base plate and pads together provide stable support for the equipment, reducing the risk of bumps caused by unstable placement. The locking strips engage with the slots of the outer casing, keeping the equipment stable during handling and use, and preventing displacement and collisions. This provides all-round protection for the equipment, especially providing effective protection for vulnerable parts such as the edges and corners of the equipment. It reduces the occurrence of problems such as shell deformation and loosening of internal parts, thereby extending the normal service life of the equipment and ensuring the stability of testing accuracy.
