Description

Technical Field

[0001] The invention relates to an electric plug buffer device, belonging to the technical field of plug and socket testing. Background Art

[0002] The comprehensive performance test of model products mainly involves functional testing and simulation testing of each product under the model to ensure the performance reliability of each product in the subsystem. However, due to various reasons, the complete set of control systems produced in conjunction with the model is not tested jointly.

[0003] The purpose of comprehensive testing is to evaluate the joint performance of all the cable networks, TC, seeker, controller, computer and other complete machines of the control system to ensure normal functions and reliability of the model control system. At the same time, comprehensive testing is the last test of the control system before the product is delivered for assembly. Its test content is relatively comprehensive and covers a wide range. It is an important means to check whether the consistency, stability, function and performance of the control system batch products meet the requirements, thereby ensuring the delivery quality of the batch products. Among all the participating products, TC cables have the largest number, and due to the particularity of the use environment, all TC cables need to be evaluated by electrical test. The current test process is that when conducting this test, the second-post operator needs to be in place in advance and hold the TC plug well. Therefore, this not only requires the tester to be extremely familiar with the test process, but also requires constant concentration. Secondly, the entire process of traditional electrical test is controlled by human operation. If the quality problems caused by negligence in the process are irreparable, the plug shell will be damaged at the least, causing product docking problems, and the function of the TC cable will be damaged at the worst, causing product repair or even scrapping, seriously affecting the delivery cycle. In addition, there is a possibility that the operator will be injured due to accidental detachment, which poses certain safety hazards. Summary of the invention

[0004] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art and propose an electrically separated plug buffer device, which, through the structural design of supporting the electrically separated plug and socket, protects the plug and socket when the plug is electrically separated, thereby improving the comprehensive measurement efficiency.

[0005] The technical solution of the present invention is:

[0006] A buffer device for an electric plug, comprising a base, a buffer pulley block, a guide rail, a supporting tool and a card slot;

[0007] The base comprises a bottom surface and door frame structures fixed at both ends of the bottom surface and placed in parallel, and the bottom surface is fixed on the work surface;

[0008] The bottom surface of the guide rail is fixed to the lower surface of the top beams of the two door frame structures, and the track is horizontal and perpendicular to the two top beams;

[0009] The buffer pulley block is located on the guide rail and can move bidirectionally along the rail;

[0010] The supporting tool is connected to the buffer pulley block and is hung below the side of the buffer pulley block away from the two door frame structures of the base based on the tension of the buffer pulley block;

[0011] The card slot is fixed on the bottom surface and is located just below the base door frame structure close to the supporting tooling; the separated static socket to be tested is fixed in the card slot, and the separated dynamic plug is fixed on the supporting tooling.

[0012] Furthermore, the supporting tooling includes a top surface, a polygonal frame and a stud; the stud is connected above the center of the top surface, and one end of the top surface is fixedly connected to the polygonal frame; the shape of the polygonal frame is designed to follow the maximum outer contour of the separation movable plug, so that the separation movable plug is fixed on the polygonal frame.

[0013] Furthermore, the supporting tooling is connected to the buffer pulley block via a nested buckle, the nested buckle is fixed on the buffer pulley block, and the nut in the nested buckle is threadedly connected to the stud of the supporting tooling; the height of the supporting tooling is adjusted by adjusting the nut in the nested buckle.

[0014] Furthermore, two through holes are opened at one end of the top surface of the supporting tooling, and one side of the polygonal frame is connected to the two through holes, thereby realizing a detachable design of the polygonal frame.

[0015] Furthermore, the buffer pulley block has a bidirectional braking function, and includes a pulley, a bearing and a buffer pressure rod.

[0016] Furthermore, the pulley is preferably an integrally molded wheel made of PA66 nylon.

[0017] Furthermore, soft anti-static sponges are pasted on the inner surfaces of the card slot and the supporting tooling at the locations that are in contact with the separated static socket and the separated dynamic plug respectively.

[0018] Furthermore, the entire base is made of aluminum alloy.

[0019] Furthermore, two G-shaped calipers are included to reinforce the side where the groove is set on the bottom surface.

[0020] The advantages of the present invention compared with the prior art are:

[0021] (1) In order to ensure the accuracy and safety of the docking of the two ends of the TC cable, the present invention adopts a nested buckle method to achieve horizontal angle adjustment of the detachable supporting tooling, and adjusts the overall vertical height through the internal nut of the nested structure to avoid damage to the pins and holes inside the two ends of the TC due to angle problems.

[0022] (2) The supporting fixture of the present invention is designed to be detachable. By replacing supporting fixtures of different sizes, different specifications of electrical plugs can be tested. In order to ensure that the fixture does not fall off when the product rebounds, the fixture adopts a limit design that matches the product's appearance and structure to ensure that the product will not fall off the fixture, further improving safety and reliability.

[0023] (3) The present invention adopts a bidirectional hydraulic buffer lifting wheel to prevent the product from being separated from the tooling due to excessive impact during electrical separation, and can also prevent the product from sliding toward the docking plug due to reaction force, thereby protecting the tested product from being safely separated from the test tooling.

[0031] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0032] The present invention proposes a buffer device for an electric plug, such as Figure 1 As shown, it includes a G-shaped caliper 1, a base 2, a buffer pulley block 3, a slide rail, a detachable supporting tooling 4, and a slot 5.

[0033] The G-shaped caliper 1 serves to fix the base 2. Figure 2 As shown, to prevent the risk of the device and the product to be tested falling due to excessive weight.

[0034] The base 2 includes a bottom surface and door frame structures fixed at both ends of the bottom surface and placed in parallel. Figure 3 As shown, the bottom surface is fixed on the work surface;

[0035] The bottom surface of the guide rail is fixed to the lower surface of the two door frame structure top beams. The track is horizontal and perpendicular to the two top beams. Figure 4 As shown;

[0036] Considering the large size and weight of the cable plug, the base 2 is made of aluminum alloy throughout, which has good stability and heavy load-bearing capacity, and can meet the weight requirements of the entire system.

[0037] The buffer pulley block 3 can prevent the product from being separated from the tooling due to excessive impact during electrical time-sharing through a bidirectional hydraulic buffer hanging wheel, and can also prevent the product from sliding toward the docking plug due to the reaction force, thus protecting the tested product from being safely separated from the test tooling. The buffer pulley block 3 uses a one-piece molded wheel made of PA66 nylon, wear-resistant and silent imported bearings, and a buffer pressure rod, which can bear more than 200 kilograms.

[0038] Removable carrier 4 Figure 5 As shown, it is convenient for testers to replace the tested products. In addition, this device can be disassembled and replaced with supporting tools of different sizes, which can be extended to other electric plugs of different specifications. In order to ensure that the product will not fall off the tooling when it rebounds, a limit device that matches the product's appearance and structure is designed on the tooling to ensure that the product will not fall off the tooling, further improving safety and reliability. The supporting device is designed to be detachable and replaceable, which is convenient for subsequent TC cable plugs of other specifications and brands to be tested for electric separation. It only needs to replace the detachable supporting tooling 4 of the corresponding size. In addition, in order to ensure the accuracy and safety of the docking of the two ends of the TC cable, the connection method and adjustability between the track and the detachable supporting tooling 4 need to be cleverly conceived. It must be ensured that the detachable supporting tooling 4 can be adjusted 360 degrees in the horizontal direction before docking, and the height can be adjusted up and down. In this way, the accuracy of docking can be guaranteed, and the pins and holes inside the two ends of the TC can be avoided from being damaged due to angle problems. In response to this problem, the nested buckle method is adopted to achieve horizontal angle adjustment, and the overall up and down height is adjusted by the internal nut of the nested structure.

[0039] The card slot 5 is used to prevent the product from rebounding due to recoil. Figure 6 As shown, the fixed end of the TC will not be bounced due to the reaction force. The card slot 5 can also be disassembled and adjusted, which is convenient for later expansion.

[0040] The specific implementation method is as follows: Use a G-shaped caliper 1 to fix the base 2 on a flat table, fix the separation static socket in the card slot 5, fix the separation dynamic plug on the detachable support tooling 4, adjust the height of the detachable support tooling 4 up and down to make the separation dynamic plug dock with the separation static socket, and after installation, the product is tested for normal functions. When testing the separation function of the product, the dynamic plug and static socket automatically pop open, and the dynamic separation plug bounces to the end of the track with the track. Due to the existence of damping, the plug is stuck when it slides to the end of the track and will not rebound. At the same time, the static separation plug is fixed on the base card slot 5 to prevent the product from rebounding due to recoil.

[0041] The device is used in the comprehensive test of a certain type of product. After hundreds of repeated verifications, the device will not damage the plug during the electrical separation process, and the tester does not need to hold the plug with his hands to ensure the safety of the personnel. This device has played a good role in protecting the safety of both products and personnel, avoiding unnecessary economic losses. The use of this device has simplified the extra operations of operators, improved efficiency, and saved economic expenses.

[0042] It can be proved from the examples that the application of the electric plug buffer device, on the one hand, avoids the accidental separation of the product without protective measures due to the tester's mistaken touch, negligence, etc., and eliminates the quality risks during the electric plug test. On the other hand, it can greatly reduce the operating burden of the debugging personnel and simplify the test operation process. In addition, the device has strong expansion and versatility, and can be well promoted in this field in the future.

[0043] The above-described embodiments are only preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
