Description

Technical Field

[0001] This application relates to the technical field of plug and socket fixing fixtures, and in particular to a fixing fixture for a plug and socket breaking capacity testing machine. Background Technology

[0002] A plug and socket breaking capacity tester is a device specifically designed to test the performance and lifespan of plugs and sockets after a certain number of insertions and removals. This tester can be connected to an electrical accessory load cell to assess the electrical life of plugs and sockets, and is also suitable for performing normal operation and breaking capacity tests.

[0003] Existing fixed fixtures are not easy to align plugs and sockets accurately. When changing plugs or sockets, it is necessary to constantly readjust the position between the plug and socket to make the plug and socket correspond. The efficiency of plug and socket replacement is too slow, which affects the overall test time. Utility Model Content

[0004] The purpose of this application is to provide a fixture for a plug and socket breaking capacity testing machine to improve the efficiency of plug and socket replacement.

[0005] The fixing fixture for a plug and socket breaking capacity testing machine provided in this application adopts the following technical solution: it includes a test bench, the test bench is connected to a first mounting plate and a second mounting plate, the first mounting plate is connected to a positioning component for positioning the socket and a first clamping component for clamping the socket, the second mounting plate is connected to a positioning component for positioning the plug and a second clamping component for clamping the plug, and the test bench is connected to a driving component for driving the second mounting plate to slide towards or away from the first mounting plate.

[0006] By adopting the above technical solution, after a socket is tested, the first clamping component releases the socket, and the new socket is positioned by the positioning component, so that the socket is accurately installed in the corresponding position, thereby improving the installation efficiency of the socket; after a plug is tested, the first clamping component releases the plug, and the new plug is positioned by the positioning component, so that the plug is accurately installed in the corresponding position, thereby improving the installation efficiency of the plug and improving the overall testing efficiency of the plug and socket.

[0007] Optionally, the positioning component includes two positioning plates connected to the first mounting plate, with a first mounting groove formed between the two positioning plates for the socket to engage.

[0008] By adopting the above technical solution, when installing a new socket, the socket snaps into the first mounting groove, and the outer surface of the socket abuts against the opposite side of the two positioning plates. The two positioning plates restrict the horizontal movement of the socket, thereby playing a positioning role in the installation of the socket and improving the installation efficiency of the socket.

[0009] Optionally, the two positioning plates are slidably connected to the first mounting plate, and the first mounting plate is rotatably connected to two first lead screws. The two positioning plates are threadedly connected to the two first lead screws respectively, and both positioning plates abut against the first mounting plate.

[0010] By adopting the above technical solution, when it is necessary to inspect a batch of sockets with larger or smaller sizes, the corresponding lead screw is rotated to adjust the distance between the two positioning plates, thereby adapting to sockets of different sizes and enabling the two positioning plates to position sockets of different sizes.

[0011] Optionally, the positioning plate is connected to a guide block, the first mounting plate is provided with a guide groove for sliding cooperation with the guide block, and the first lead screw is threadedly connected to the guide block.

[0012] By adopting the above technical solution, when the positioning plate slides, the guide block slides along the guide groove. The sliding cooperation between the guide block and the guide groove guides and limits the sliding of the positioning plate, thereby improving the stability of the positioning plate's sliding. The threaded connection between the first lead screw and the guide block prevents the first lead screw from affecting the installation of the socket and provides space for the socket installation.

[0013] Optionally, the first clamping assembly includes a first clamping plate slidably connected to the first mounting plate and a second lead screw threadedly connected to the first mounting plate. The first clamping plate abuts against the first mounting plate, the first clamping plate is connected to a first bearing, and the second lead screw is connected to the first bearing.

[0014] By adopting the above technical solution, after the socket is positioned, the second lead screw is rotated in the direction closer to the socket, that is, the first clamping plate moves in the direction closer to the socket until the socket is clamped by the first clamping plate and the first mounting plate, thereby improving the stability of the socket installed on the first mounting plate; when the socket is tested, the second lead screw is rotated in the direction away from the socket, that is, the first clamping plate moves in the direction away from the socket, and the first clamping plate releases the socket, making it easy to replace.

[0015] Optionally, the second mounting plate is provided with a second mounting groove for the plug to be inserted, and the positioning member is a support plate connected to the inner wall of the second mounting groove.

[0016] By adopting the above technical solution, the plug is inserted into the second mounting slot, and the support plate supports the plug, thereby positioning the height of the plug and ensuring that the plug is accurately installed in the corresponding position, thus improving the installation efficiency of the plug.

[0017] Optionally, the support plate is slidably connected in the second mounting groove, the support plate is connected to the inner wall of the second mounting groove by an elastic element, and the second mounting plate is threadedly connected with a threaded rod for abutting against the support plate.

[0018] By adopting the above technical solution, rotating the threaded rod towards the support plate causes the threaded rod to abut against the support plate and lift the support plate. The elastic element is stretched and undergoes elastic deformation, maintaining a tendency to elastically return to its original position. Rotating the threaded rod away from the support plate causes the elastic element to elastically return to its original position, i.e., the support plate to return to its original position, thereby increasing the height of the support plate, i.e., adjusting the installation position of the plug.

[0019] Optionally, the support plate is connected to a guide post, and the second mounting plate is provided with a guide hole for sliding cooperation with the guide post, the guide hole communicating with the second mounting groove.

[0020] By adopting the above technical solution, when the support plate slides, the guide column slides along the guide hole. The sliding cooperation between the guide column and the guide hole plays a guiding and limiting role in the sliding of the support plate, thereby improving the stability of the support plate sliding.

[0021] Optionally, the second clamping assembly includes a second clamping plate slidably connected in the second mounting groove and a third lead screw threadedly connected to the second mounting plate. The second clamping plate abuts against the second mounting plate, the second clamping plate is connected to a second bearing, and the third lead screw is connected to the second bearing.

[0022] By adopting the above technical solution, after the plug is positioned, the third screw is rotated in the direction closer to the plug, that is, the second clamping plate moves in the direction closer to the plug until the plug is clamped by the second clamping plate and the second mounting plate, thereby improving the stability of the plug mounted on the second mounting plate; when the plug is detected, the third screw is rotated in the direction away from the plug, that is, the second clamping plate moves in the direction away from the plug, and the second clamping plate releases the plug, making it easy to replace.

[0023] Optionally, the test bench is provided with a connecting plate, which is connected to the second mounting plate by a number of connecting columns, and a number of shock-absorbing springs are connected between the connecting plate and the second mounting plate.

[0024] By adopting the above technical solution, when the plug is impacted, the shock-absorbing spring can absorb the energy and reduce damage to the plug.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. After a socket is tested, the first clamping component releases the socket, and the new socket is positioned by the positioning component, so that the socket is accurately installed in the corresponding position, improving the installation efficiency of the socket; after a plug is tested, the first clamping component releases the plug, and the new plug is positioned by the positioning component, so that the plug is accurately installed in the corresponding position, improving the installation efficiency of the plug and improving the overall testing efficiency of the plug and socket.

[0027] 2. When installing a new socket, the socket snaps into the first mounting slot, and the outer surface of the socket abuts against the opposite side of the two positioning plates. The two positioning plates restrict the horizontal movement of the socket, thereby positioning the socket and improving the installation efficiency. Attached Figure Description

A first mounting groove 42 for the socket to be engaged is formed between the two positioning plates 41. The first mounting plate 2 is rotatably connected to two first lead screws 21, one first lead screw 21 corresponding to one positioning plate 41. Each positioning plate 41 is connected to a guide block 411, which is integrally formed with the positioning plate 41. The first mounting plate 2 has a guide groove 22 for sliding cooperation with the corresponding guide block 411. The first lead screw 21 is threadedly connected to the corresponding guide block 411. The ends of the two first lead screws 21 that are far apart from each other are fixedly connected to a Z-shaped active rod. The first mounting plate 2 is connected to a first clamping assembly 5 for clamping the socket. The first clamping assembly 5 includes a first clamping plate 51 slidably connected to the first mounting plate 2 and a second lead screw 52 threadedly connected to the first mounting plate 2. A positioning plate 41 is located between the first clamping plate 51 and the test bench 1. The first clamping plate 51 is located between the positioning plate 41 and the second lead screw 52.
