Description

Technical Field

[0001] This invention relates to the technical field of wiring fixtures, specifically a quick wiring device for an acceleration testing machine. Background Technology

[0002] Acceleration testing is an essential mechanical test in GJB (General Technical Standards), primarily assessing the stability of product fasteners and structural components. Currently, our factory's acceleration testing room and control room are separated. The connection between the product and one end of the connector is conducted in the testing room, while the connection between the test bench and the other end of the connector is conducted in the control room. The product is powered on and loaded via the connection of the terminal block.

[0003] The existing terminal blocks are connected with nuts, which can easily cause poor contact, leading to abnormalities in acceleration tests. This requires re-inspection, greatly increasing the workload. Furthermore, some terminal blocks on the accelerometer arm lack matching screws, and some have stripped screw threads and broken connection pieces. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quick-connection device for an acceleration testing machine. This solves the problems of using nuts to connect the terminal blocks, which can easily lead to poor contact, causing abnormalities in acceleration tests and requiring repeated troubleshooting, greatly increasing the workload. Furthermore, the terminal blocks on the accelerometer's rotating arm lack matching screws, and some also suffer from stripped screws and broken connection pieces.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick wiring device for an acceleration testing machine, comprising a housing, wherein grooves are symmetrically arranged inside the upper end of the housing, and boosters are rotatably connected inside the grooves, and the two side walls at the ends of the boosters are rotatably connected to the two side walls inside the grooves via rotating shafts, and extrusion columns are connected to the lower side walls of the boosters, and terminals are fixedly connected to the lower side walls of the extrusion columns, wherein placement grooves are symmetrically arranged inside the housing, and through holes are provided inside the bottom surface of the grooves, and the extrusion columns penetrate through the through holes and extend into the placement grooves, wherein the terminals are used to extrude cables.

[0006] Preferably, the inner sidewalls at both ends of the housing are provided with connection holes, and the inner sidewalls of the connection holes are respectively connected to the inner sidewalls of the placement slots, thereby facilitating the placement of cables.

[0007] Preferably, the upper ends of the extrusion columns are all threadedly connected to the lower side wall of the booster, thereby facilitating the installation and fastening of cables of different sizes.

[0008] Preferably, the two ends of the limiting groove are tightly fitted to the two end sidewalls of the groove, thereby facilitating the use of a booster to fasten the cable.

[0009] Preferably, the opening size of the through hole is larger than the length between the extrusion post and the terminal block, thereby facilitating the movement of the extrusion post.

[0010] Preferably, the left sidewall of the housing is symmetrically fixed with connecting blocks, and the right sidewall is symmetrically provided with connecting grooves. When the housings are connected to each other, the connecting blocks are slidably connected to the inside of the connecting grooves, thereby facilitating the connection between adjacent housings.

[0011] This invention provides a quick-connection device for an acceleration testing machine. It has the following advantages: This quick-connection device for an acceleration testing machine, when using the wiring fixture, uses a booster to squeeze and clamp the placed cable, which can conveniently and securely place the connected cable, and at the same time protect the connecting wire.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-3This invention provides a quick-connection device for an acceleration testing machine, comprising a housing 1. The upper end of the housing 1 has symmetrically arranged grooves 5. Boosters 6 are rotatably connected inside the grooves 5, and the two sidewalls at the ends of the boosters 6 are rotatably connected to the two end sidewalls of the grooves 5 via rotating shafts. Extrusion columns 9 are connected to the lower end sidewalls of the boosters 6, and terminals 7 are fixedly connected to the lower end sidewalls of the extrusion columns 9. The housing 1 has symmetrically arranged placement grooves 8. Through holes 10 are provided inside the bottom surface of each groove 5, and the extrusion columns 9 penetrate through the through holes 10 and extend into the placement grooves 8. The terminals 7 are used to extrude cables. Connection holes 4 are provided inside the two end sidewalls of the housing 1, and the interiors of the connection holes 4 are respectively connected to the interiors of the placement grooves 8. The upper ends of the extrusion columns 89 are threadedly connected to the lower end sidewalls of the boosters 6. The two ends of the limiting grooves 5 are tightly fitted to the two end sidewalls of the grooves 5. The opening size of the through holes 10 is larger than the distance between the extrusion columns 9 and the terminals 7. The length and size of the housing 1 are such that connecting blocks 2 are symmetrically fixedly installed on the left side wall, and connecting grooves 3 are symmetrically arranged inside the right side wall. When the housing 1 is connected to each other, the connecting blocks 2 are slidably connected to the inside of the connecting grooves 1. When performing an acceleration test, first strip 9-10mm of the wire insulation layer, open the booster 6 to stand upright, insert the corresponding wire into the interface, press down the booster 6 to complete the wiring, open the booster 6, and pull out the wire to complete the disassembly. Connecting and disassembling the wire is quick, effectively shortening the preparation time for the acceleration test. This quick-connect terminal is suitable for wires of 0.08-4mm2, and can withstand a rated voltage of 450V and a rated current of 32A, which can meet the test requirements of product acceleration tests. In addition, for the original acceleration cables that were too large, we have also made the squeezing column 9 on the lower side wall of the rotating arm, that is, the rotatable booster 6, smoother, so as to facilitate the replacement of different sized terminals 7. The new terminals 7 can meet the needs of thicker cables.

[0016] It should be noted that, in this embodiment, as Figure 1-3 As shown, during acceleration testing, first strip 9-10mm of the wire insulation, then pry the booster 6 upright, insert the corresponding wire into the interface, and press down the booster 6 to complete the wiring. Prying the booster 6 open and pulling out the wire completes the disconnection. This quick-connect and disconnection method effectively shortens the preparation time for acceleration tests. This quick-connect terminal is suitable for wires from 0.08 to 4mm², and can withstand a rated voltage of 450V and a rated current of 32A, meeting the testing requirements for product acceleration tests. Furthermore, for older acceleration cables with larger diameters, we have made the pressing column 9 smoother on the lower side wall of the rotating booster 6, facilitating the replacement of different sized terminals 7. The new terminal 7 can meet the needs of thicker cables.
