[0003] The traditional manual testing method is to manually insert a plug into the socket and observe the connectivity between the two. This testing method is easily affected by the operator's skills and status, resulting in poor consistency and repeatability of the test results. On the other hand, it is difficult to accurately control the speed and force of plugging and unplugging, and cannot simulate the high-frequency plugging and unplugging operations in real-world environments. While consuming a lot of time and manpower, it cannot meet the required test requirements and standards. Utility Model Content

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figures 1 to 3 As shown, the utility model provides a cyclic plug-in and pull-out test device for testing the durability of the copper sheet inside the socket 10, comprising: a frame 2; at least one set of placement tables 3, which are arranged on the frame 2, and the placement tables 3 are used to fix several sockets 10 to be tested at equal distances; a testing mechanism 4, which is arranged above the placement tables 3, and the testing mechanism 4 includes a pressure sensor 40 and several plugs 11, and the several plugs 11 are arranged in a one-to-one correspondence with the sockets 10, and each plug 11 and the active end of the testing mechanism 4 are connected to a pressure sensor 40; the pressure sensor 40 can be driven by the testing mechanism 4 and moved synchronously with the plug 11 toward the placement table 3, and when the plug 11 is movably inserted into the socket 10, it is used to detect the test value during insertion.

[0031] This embodiment is mainly used to test the durability of the copper sheet in the socket 10. Specifically, Figures 1 to 3As shown, a worker or a manipulator can fix several sockets 10 to be tested on the placement table 3 at equal distances to ensure that the position of each socket 10 is accurate, to avoid interference between two adjacent sockets 10 during the test process and to affect the smoothness of the overall test. As the plug 11 to be tested is synchronously installed on the test mechanism 4, after ensuring that each plug 11 is aligned with the corresponding socket 10, the test mechanism 4 can simultaneously drive the pressure sensor 40 and the plug 11 to approach the socket 10. When the plug 11 is movably inserted into the socket 10, the pressure sensor 40 starts to work normally, and relies on the connection between the pressure sensor 40 and the external control system to transmit the insertion force data. Similarly, when the test mechanism 4 drives the plug 11 to be pulled out of the socket 10, the pressure sensor 40 can also detect the corresponding extraction force, repeat the above-mentioned insertion and extraction operations, and finally obtain the required test value, so as to judge whether the durability of the copper sheet in the socket 10 can meet the required usage requirements. It can be seen that through the automated testing mechanism 4, multiple sockets 10 can be plugged and unplugged tested at the same time, which greatly improves the test efficiency and shortens the test cycle. No manual intervention is required during the test process. The pressure sensor 40 is used to detect the plugging and unplugging force in real time to ensure the consistency and accuracy of the test data. While achieving precise control of speed and force, it can also effectively simulate high-frequency plugging and unplugging operations in actual use environments, thereby improving the authenticity and reliability of the test.

[0032] It should be noted that, in this embodiment, two sets of placement tables 3 and testing mechanisms 4 are provided. The two sets of equipment can perform tests alternately, further improving the efficiency of the test and being suitable for quality inspection during mass production.

[0033] The testing mechanism 4 also includes: a mounting bracket 41, which is arranged on the frame 2; a driving member 42, which is arranged on the mounting bracket 41 in the vertical direction, with the movable end of the driving member 42 facing the placement table 3 at the bottom, and the movable end of the driving member 42 is connected to the mounting plate 420, one side of the pressure sensor 40 is connected to the mounting plate 420, and the other side is connected to the plug 11 to be tested; a guide member 43, which is connected to the mounting plate 420 and is movably inserted into the mounting bracket 41, for guiding the pressure sensor 40 and the plug 11 to move back and forth in the vertical direction.

[0034] like Figure 1 and Figure 3As shown, after the plug 11 and socket 10 to be tested are placed in place respectively, the test parameters, including the plugging and unplugging frequency (for example, 20-30 times / minute), the number of plugging and unplugging times (for example, 5000 times), etc., are set through the control system. At this time, the movable end of the driving member 42 can drive the pressure sensor 40 and the plug 11 to move closer to or away from the socket 10. In this process, in order to meet the plugging and unplugging frequency between the plug 11 and the socket 10, this embodiment connects the guide member 43 to the mounting plate 420 and movably inserts it into the mounting bracket 41 to ensure that the guide member 43 can guide the pressure sensor 40 and the plug 11 to always move back and forth in the vertical direction, thereby improving the accuracy and stability during plugging and connecting, and also providing a guarantee for the reliability of the test data.

[0035] Preferably, the driving member 42 in this embodiment preferably adopts an electric cylinder, which is a modular product that integrates a servo motor and a screw. Compared with structures such as hydraulic cylinders and pneumatic cylinders commonly used in machinery, the electric cylinder can accurately and stably realize the reciprocating movement of the pressure sensor 40 and the plug to be tested 11, thereby effectively meeting the plugging and unplugging frequency required during testing.

[0036] The guide member 43 includes a guide column 430 and a guide sleeve 431 . The guide sleeve 431 is detachably connected to the mounting bracket 41 . One end of the guide column 430 is connected to the top wall of the mounting plate 420 , and the other end is movably inserted into the guide sleeve 431 .

[0037] Further, if Figure 3 As shown, the guide sleeve 431 is arranged in a T-shape as a whole, so that the guide sleeve 431 can be installed on the mounting plate 420 in a vertical position. Since the pressure sensor 40 and the plug 11 are both located on the mounting plate 420, one end of the guide column 430 is connected to the top wall of the mounting plate 420, and the other end is movably inserted into the guide sleeve 431, so that when the driving member 42 drives the pressure sensor 40 and the plug 11 to move back and forth in the vertical direction, it can rely on the cooperation between the guide column 430 and the guide sleeve 431 to effectively guide and limit the direction of the reciprocating movement of the pressure sensor 40 and the plug 11, thereby ensuring smoothness during plugging and unplugging and accuracy in detecting the plugging and unplugging force.

[0038] A connecting frame 400 is further provided at the bottom of the pressure sensor 40 , and the plug 11 to be tested is detachably connected to the connecting frame 400 .

[0039] Preferably, since the plug 11 to be tested needs to be frequently replaced after the test is completed, in order to ensure that the pressure sensor 40 is not affected, a connecting frame 400 is arranged at the bottom of the pressure sensor 40, that is, when the plug 11 to be tested is replaced each time, the plug 11 can be simply detached from the connecting frame 400 without touching the pressure sensor 40, effectively preventing the pressure sensor 40 from being misaligned to affect the authenticity and accuracy of the test value.

[0040] The mounting bracket 41 is further provided with a support column 410 and a clamping block 411. The support column 410 is inserted into the mounting bracket 41, and the clamping block 411 is movably sleeved on the support column 410 and abuts against the mounting bracket 41 or the rack 2, so as to fix the mounting bracket 41 on the support column 410.

[0041] Further, as shown in Figure 3 , the support column 410 is installed in a vertical posture between the rack 2 and the mounting bracket 41. In order to ensure the stability of the mounting bracket 41, the top end of the support column 410 is inserted into the mounting bracket 41, and the bottom end is inserted into the rack 2. Then, the clamping block 411 (composed of two half-ring blocks) is sleeved on the support column 410. It should be noted that the clamping block 411 in this embodiment is also T-shaped as a whole. Such a design is conducive to connecting the top wall of the clamping block 411 to the bottom wall of the mounting bracket 41. At the same time, the clamping block 411 is detachably connected with a locking screw. After the locking screw fixes and connects the clamping block 411 (i.e., connects the two half-ring blocks tightly with each other), the clamping block 411 is locked on the support column 410, thereby realizing the stable connection between the mounting bracket 41 and the support column 410. The overall structure is simple, convenient and fast to operate, and effectively ensures the smoothness and stability of the test mechanism 4 during the test operation. Preferably, the fixing connection between the bottom end of the support column 410 and the rack 2 can also be achieved by using the above structure, and the structure and working principle are the same, which will not be described in detail here.

[0042] The placement table 3 comprises: a fixing seat 30 installed on the rack 2; a support plate 31 connected to the fixing seat 30 at both ends, the support plate 31 being formed with a placement groove 310 and an avoiding opening 311, the placement groove 310 being used to limit the movement of the socket 10 to be tested relative to the support plate 31; the socket 10 being hingedly connected with a protective cover 100, one side of the avoiding opening 311 being communicated with the placement groove 310, and the other side being communicated with the outside of the support plate 31, so as to provide a placement space for the protective cover 100.

[0043] As shown in Figure 1 and Figure 2As shown, in order to install and place the socket 10 to be tested, this embodiment forms a number of equally spaced placement grooves 310 on the support plate 31. The placement grooves 310 are provided with threaded holes. While limiting the horizontal displacement of the socket 10 to be tested, the socket 10 to be tested can also be fixed in the placement grooves 310 by screws or other components, ensuring that the socket 10 can always maintain absolute stability during frequent plugging and unplugging operations. In addition, since the present embodiment tests a triangular plug 11 and a triangular universal socket 10 with a protective cover 100, an avoidance opening 311 is connected to one side of the placement groove 310. The avoidance opening 311 can provide a placement space for the protective cover 100, so that the protective cover 100 can be opened or closed during the test process, facilitating operation and protecting the socket 10.

[0044] Preferably, if Figure 2 As shown, this embodiment also includes several support blocks 20 on the rack 2. Since the support plate is provided with several placement slots 310, to ensure that the multiple sockets 10 to be tested are at the same level, the top of the support block 20 abuts against the bottom wall of the support plate 31, so that the support plate 31 can always maintain a horizontal posture. This improves the overall structural stability of the placement platform 3 while also ensuring the accuracy of subsequent frequent plugging and unplugging of the plug 11 and the socket 10. It should be noted that the fixed connection between the bottom end of the support block 20 and the rack 2 can be achieved by using the above-mentioned clamping block 411 structure, which will not be described in detail here.

[0045] Preferably, a button 312 for tool switching is also provided on the support plate 31 in this embodiment. Since two groups of placement tables 3 and test mechanisms 4 are provided in this embodiment, the tool opening and closing can be effectively realized through the button 312, which brings convenience to the operation when replacing the plug 11 to be tested.

[0046] It should be noted that the detachable connection referred to in this embodiment can be installed and removed using screws, screws and other connecting components. In addition, the socket 10 in this embodiment is a universal socket 10, the maximum standard for the socket 10 extraction force is 50N, and the single riveting tensile force standard is defined as 5KGF.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0049] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0050] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
