Description

Technical Field

[0001] This application relates to the technical field of electrical switch manufacturing, and particularly to a socket testing tooling. Background Art

[0002] A protection door structure is usually provided in a socket. The protection door structure is located between the socket holes and the socket sleeves of the socket, and is used to prevent objects from accidentally entering the socket sleeves through the socket holes, playing a role in preventing electric leakage.

[0003] At present, some sockets with protection doors on the market are difficult to insert plugs during actual use, resulting in the need to shake the plug left and right to insert it into the socket during use. Even for some sockets, it is difficult to insert the plug into the socket holes even when the plug is shaken left and right, seriously affecting the user experience.

[0004] Therefore, it is necessary to test the socket before leaving the factory to ensure that the socket can be used normally. Utility Model Content

[0005] This application provides a socket testing tooling, which can perform an insertion test on the socket to assist in eliminating unqualified sockets.

[0006] A socket testing tooling provided by this application includes a socket fixture, a plug fixing member, a driving mechanism, and an angle adjusting mechanism. The socket fixture is used to clamp the socket to be tested; the plug fixing member is disposed opposite to the socket fixture, and a plug is provided on the surface of the plug fixing member facing the socket fixture; the driving mechanism is drivingly connected to the plug fixing member and is used to drive the plug fixing member to approach or move away from the socket fixture; the angle adjusting mechanism is used to adjust the angle between the plug fixing member and the socket fixture so that the plug is inserted into the socket holes of the socket at a preset angle.

[0007] Through the above solution, the socket to be tested is clamped on the socket fixture, and then by operating the driving mechanism, the driving mechanism drives the plug fixing member to approach the socket fixture, thereby inserting the plug into the socket. Among them, the angle adjusting mechanism can adjust the angle between the plug fixing member and the socket fixture to a preset angle. When the plug can be inserted into the socket at the preset angle, the plug can generally also be inserted into the socket in the direction directly facing the socket. Therefore, by using the above socket testing tooling, it is judged whether the socket is qualified according to whether the plug can be inserted into the socket at the preset angle, that is, if the plug can be smoothly inserted at the preset angle, the socket is qualified, and if the plug cannot be smoothly inserted at the preset angle, the socket is unqualified. Thus, an insertion test is performed on the socket, which can assist in eliminating unqualified sockets and is beneficial to improving the user experience.

[0008] In a possible design, the socket test tooling further includes a moving member, the moving member is connected to the driving mechanism, and the plug fixing member is connected to the moving member; the angle adjusting mechanism includes a connecting member, a pressing member, and an adjusting groove provided on the plug fixing member. The connecting member passes through the plug fixing member and is connected to the moving member so that the plug fixing member can rotate around the connecting member; the adjusting groove is arranged along an arc trajectory with the connecting member as the center of the circle, and the pressing member passes through the adjusting groove and is connected to the moving member. When the pressing member is tightened on the moving member, the end of the pressing member abuts against the plug fixing member.

[0009] With this embodiment, the moving member is connected to the driving mechanism. Thus, when the driving mechanism drives the moving member to move, it can drive the plug fixing member to move. When the angles of the moving member and the socket fixture remain unchanged, by adjusting the angle of the plug fixing member relative to the moving member, the angle between the plug fixing member and the socket fixture can be adjusted, and further the angle between the socket and the plug can be adjusted. The specific usage method and principle of the above angle adjusting mechanism are as follows: The connecting member can realize the initial positioning of the plug fixing member and the moving member, so that the plug fixing member can still maintain its connection with the moving member when the pressing member is loose. When it is necessary to adjust the angle of the plug fixing member, loosen the pressing member so that the pressing member no longer presses tightly against the plug fixing member, and then rotate the plug fixing member with the connecting member as the center of the circle. At this time, the first pressing member moves in the adjusting groove. When the plug fixing member rotates to the set angle, tighten the pressing member so that the pressing member presses the plug fixing member against the moving member, and the adjustment of the angle of the plug fixing member can be completed, and further the adjustment of the angle between the plug and the socket can be realized. The use of this angle adjusting mechanism is simpler and the operation is more convenient.

[0010] In a possible design, the angle adjusting mechanism further includes a first angle pointer and a first angle scale. The first angle pointer is connected to the plug fixing member, and the first angle scale is fixed at the corresponding position of the first angle pointer. When adjusting the angle of the plug fixing member, the first angle pointer swings relative to the first angle scale to indicate the angle of the plug fixing member relative to the socket fixture.

[0011] With this embodiment, the angle of the plug fixing member can be known through the position indicated by the first angle pointer on the first angle scale, so as to facilitate accurately adjusting the plug fixing member to the preset angle.

[0012] In a possible design, the angle adjusting mechanism further includes a second angle pointer and a second angle scale. The second angle pointer is connected to the connecting member, and the second angle scale is arranged on the plug fixing member and is located at the corresponding position of the second angle pointer. When adjusting the angle of the plug fixing member, the second angle scale swings relative to the second angle pointer so that the second angle pointer indicates the angle of the plug fixing member relative to the socket fixture.

[0013] With this embodiment, the connecting member is connected to the moving member and will not rotate with the rotation of the plug fixing member. Therefore, by connecting the second angle pointer to the connecting member, it can be ensured that the second angle pointer does not rotate with the plug fixing member. When the plug fixing member rotates, the plug fixing member drives the second angle scale to rotate, causing the scale on the second angle scale to deviate from the second angle pointer by a certain angle, thereby facilitating the precise adjustment of the plug fixing member to the preset angle.

[0014] In a possible design, the socket testing tooling further includes a base disposed below the socket fixture. The base protrudes with a first limiting portion and a second limiting portion. A part of the socket fixture is located between the first limiting portion and the second limiting portion, and the angle between the base and the socket fixture is adjustable. The angle adjusting mechanism includes an abutting member connected to the first limiting portion, and one end of the abutting member passes through the first limiting portion and abuts against the socket fixture to press the socket fixture against the second limiting portion.

[0015] With this embodiment, when the angle between the base and the plug fixing member remains unchanged, adjusting the angle between the socket fixture and the base can achieve the effect of adjusting the angle between the socket fixture and the plug fixing portion, and further achieve the effect of adjusting the relative angle between the socket and the plug. After the angle between the socket fixture and the base is adjusted, tighten the abutting member so that the abutting member presses the socket fixture against the second limiting portion, thereby realizing the fixation of the socket fixture and the base at the preset angle.

[0016] In a possible design, the angle adjusting mechanism further includes an inner cylindrical surface and an outer cylindrical surface. The central axes of the inner cylindrical surface, the outer cylindrical surface, and the abutting member are parallel. The inner cylindrical surface is a surface of the base, and the outer cylindrical surface is a surface of the socket fixture. The inner cylindrical surface and the outer cylindrical surface are adapted to adjust the angle between the socket fixture and the base when they are in contact with each other.

[0017] With this embodiment, when adjusting the angle between the socket fixture and the base, there is no need to pick up the socket fixture. Instead, keep the inner cylindrical surface and the outer cylindrical surface in contact at all times and rotate the socket fixture in the contact state, which is labor-saving and more convenient to operate. In addition, since the inner cylindrical surface and the outer cylindrical surface are in surface contact at any angle, after the angle of the socket fixture is fixed, when the plug presses the socket, the socket fixture can withstand a greater extrusion force and maintain the stability of the angle and position, and is not easily deflected in angle and displaced.

[0018] In a possible design, the base includes a first base and a second base. The second base is located on the side of the first base close to the socket fixture. A position adjustment mechanism is provided between the first base and the second base. The position adjustment mechanism includes a longitudinal waist-shaped slot provided on the first base, a transverse waist-shaped slot provided on the second base, and a connecting bolt passing through the longitudinal waist-shaped slot and the transverse waist-shaped slot. A nut is connected to the end of the connecting bolt. The nut and the bolt head of the connecting bolt clamp the first base and the second base, and when the nut is loosened, the first base and the second base can move relative to each other along the direction of the longitudinal waist-shaped slot or the transverse waist-shaped slot.

[0019] Through this embodiment, when the nut is loosened, by moving the first base and the second base relative to each other along the direction of the longitudinal waist-shaped slot or the transverse waist-shaped slot, the relative position between the first base and the second base can be adjusted, and then the position of the socket fixture can be adjusted, so that it can adapt to the position of the plug after the relative angle between the socket and the plug is adjusted, avoiding the situation that the plug and the socket hole are difficult to insert because they cannot be aligned.

[0020] In a possible design, the plug fixture includes a first fixture and a second fixture. The second fixture is detachably connected to the first fixture. The first fixture is drivingly connected to a driving mechanism. The plug is provided on the second fixture.

[0021] Through this embodiment, when testing sockets of different specifications and different types of plugs need to be replaced, only the second fixture can be removed at this time, and the second fixture with another type of plug can be installed on the first fixture to realize the replacement of the plug, without the need to disassemble and replace the entire plug fixture, saving time and processes and reducing costs.

[0022] In a possible design, the socket fixture includes a bottom wall, a fixed wall, a movable wall, a connecting wall, and a first screw. The fixed wall and the connecting wall are connected to the side of the bottom wall facing the plug fixture. The movable wall is provided between the fixed wall and the connecting wall. The first screw is threadedly connected to the connecting wall, and one end of the first screw is rotatably connected to the movable wall. When the first screw rotates in the first direction, the first screw drives the movable wall to move towards the fixed wall to clamp the socket. When the first screw rotates in the second direction, the first screw drives the movable wall to move away from the fixed wall to loosen the socket.

[0023] Through this embodiment, the operation of clamping or loosening the socket can be achieved by rotating the first screw, which is convenient to operate and is suitable for batch testing of sockets.

[0024] In a possible design, the driving mechanism includes a second screw, a guide post and a slider. The guide post and the second screw are parallel to the direction in which the plug fixing and the socket clamp are relatively arranged. The slider passes through the guide post and the second screw and is threadedly connected to the second screw. The slider is connected to the plug fixing. When the second screw is rotated in a third direction, the second screw drives the slider to move along the guide post toward the direction close to the socket clamp to insert the plug into the socket; when the second screw is rotated in a fourth direction, the second screw drives the slider to move along the guide post toward the direction away from the socket clamp to pull the plug out of the socket.

[0025] In this embodiment, by rotating the second screw, the slider can be driven to move, and then the slider drives the plug fixing part to move, ultimately achieving the purpose of inserting the plug into the socket or pulling it out of the socket. The above-mentioned driving mechanism is simple to operate, the driving distance of the plug is accurate, and it can be started and stopped at any time, which is easy to control.

[0026] To summarize, the socket testing tool provided by the present application can be used by clamping the socket to be tested on the socket fixture, and then operating the driving mechanism to drive the plug fixing part close to the socket fixture, so as to insert the plug into the socket. The angle adjustment mechanism can adjust the angle between the plug fixing part and the socket fixture to a preset angle. When the plug can be inserted into the socket at the preset angle, the plug can generally be inserted into the socket in the direction opposite to the socket. Therefore, using the above-mentioned socket testing tool, whether the socket is qualified is judged according to whether the plug can be inserted into the socket at a preset angle. That is, if the plug can be successfully inserted at the preset angle, the socket is qualified; if the plug cannot be successfully inserted at the preset angle, the socket is unqualified. Therefore, the insertion test of the socket can assist in eliminating unqualified sockets, which is beneficial to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 The following is a schematic diagram of the overall structure of a socket test tooling provided by an embodiment of the present application. Please refer to Figure 1 , a socket test tooling provided by the present application is used to test whether a socket 700 with a switch protection door can be smoothly mated with a plug 800 at a preset angle. The socket test tooling includes a socket fixture 100, a plug fixing member 200, a driving mechanism 300, and an angle adjusting mechanism 400. The socket fixture 100 is used to clamp the socket 700 to be tested; the plug fixing member 200 is disposed opposite to the socket fixture 100, and a plug 800 is provided on a surface of the plug fixing member 200 facing the socket fixture 100; the driving mechanism 300 is drivingly connected to the plug fixing member 200 and is used to drive the plug fixing member 200 to approach or move away from the socket fixture 100; the angle adjusting mechanism 400 is used to adjust the angle between the plug fixing member 200 and the socket fixture 100 so that the plug 800 is aligned with the jack of the socket 700 and inserted at a preset angle.

[0042] The socket fixture 100 clamps the socket 700, which can ensure that the position and angle of the socket 700 will not shift during the test process, thereby ensuring the smooth progress of the test process.

[0043] The plug fixing member 200 is disposed opposite to the socket fixture 100, so that the driving mechanism 300 drives the plug fixing member 200 in a straight line direction, and the plug fixing member 200 can be driven to approach or move away from the socket fixture 100, thereby enabling the plug 800 to be inserted into or pulled out from the socket 700. Driving a component to move in a straight line direction is also the most easily implemented driving method. For example, the driving mechanism 300 can adopt a cylinder drive, a lead screw-nut drive, a linear motor drive, etc. Therefore, the manner in which the plug fixing member 200 is disposed opposite to the socket fixture 100 can simplify the structure of the driving mechanism 300.

[0044] It can be understood that the direction in which the plug fixing member 200 is disposed opposite to the socket fixture 100 can be a horizontal direction or a vertical direction, so as to facilitate operation by personnel and facilitate adjusting the angle of the plug 800 or the socket 700.

[0045] A plug 800 is fixed on the plug fixing member 200. Among them, the fixing method of the plug 800 on the plug fixing member 200 can be various. Usually, there are few types of plugs 800 on the market, generally including 10A two-pin, three-pin, and 16A three-pin. When testing sockets 700 of the same type, the specifications and positions of the plugs 800 generally do not need to be changed. Therefore, the plug 800 can be fixed on the plug fixing member 200, for example, by welding, bonding, screwing, etc., so that the plug 800 can be used for a long time during the test without falling off and shifting easily.

[0046] Among them, in the embodiments of the present application, the plug 800 used for testing can be a normally used plug 800, or it can be merely a plug 800 mold, and its material can be made of durable metal or hard plastic to increase the number of times of use in testing.

[0047] The angle adjustment mechanism 400 is used to adjust the angle between the plug fixing member 200 and the socket fixture 100, and further adjust the relative angle between the plug 800 and the socket 700. Among them, the angle adjustment mechanism 400 can only adjust the angle of the socket 700 fixture, or only adjust the angle of the plug fixing member 200, or can also adjust the angles of the plug fixing member 200 and the socket fixture 100 at the same time. It can be understood that as long as the angle of one of the plug fixing member 200 and the socket fixture 100 changes, the relative angle between the plug fixing member 200 and the socket 700 can change accordingly, and correspondingly, the purpose of inserting the plug 800 into the socket 700 at a preset angle can be achieved. Among them, the preset angle refers to the angle between the orientation of the plug 800 and the orientation of the socket holes of the socket 700. The preset angle in the embodiments of the present application is greater than 0 degrees, and usually this preset angle is the maximum deviation angle that allows the plug 800 to be inserted into the socket 700.

[0048] The reason for inserting the plug 800 into the socket 700 at a preset angle during testing is that usually when the user uses the socket 700, it is difficult to align the plug 800 with the socket 700 every time, but there will be a certain deviation. If the deviation angle is small and the plug can still be inserted, it will not affect the user experience. However, if the required deviation angle is too large, or the user needs to shake the plug 800 significantly left and right before it is possible to insert, it will affect the user experience. Therefore, a maximum deviation angle that does not affect the user experience is set as the preset angle. When the plug 800 can be inserted into the socket 700 at the preset angle, the plug 800 will surely be able to be inserted into the socket 700 in the direction directly facing the socket 700. Exemplarily, this preset angle can be ±5° or ±10° based on the situation where the plug 800 is directly facing the socket 700.

[0049] The process of testing the socket 700 using the above socket testing tooling is as follows:

[0050] S100, clamp the socket 700 to be tested on the socket fixture 100.

[0051] S200, adjust the angle between the plug fixing member 200 and the socket fixture 100 to the preset angle through the angle adjustment mechanism 400.

[0052] S300, start the driving mechanism 300 to drive the plug fixing member 200 to approach the socket fixture 100.

[0053] In S300, when the driving mechanism 300 drives the plug fixing member 200 closer to the socket fixture 100, there will be two results. One is that the plug 800 is successfully inserted into the socket 700, and the other is that the plug 800 cannot be inserted into the socket 700. If the plug 800 can be successfully inserted, the socket 700 is qualified in the insertion test. If the plug 800 cannot be inserted, the socket 700 is unqualified in the insertion test.

[0054] S400, start the driving mechanism 300 to drive the plug fixing member 200 away from the socket fixture 100.

[0055] S500, remove the socket 700 from the socket fixture 100.

[0056] Thus, the insertion test of one socket 700 can be completed.

[0057] It should be noted that in the actual use process, the preset angles of the same model of sockets 700 are often the same. At this time, only S200 needs to be executed when testing the first socket 700, and then there is no need to adjust the angle between the plug fixing member 200 and the socket fixture 100 anymore.

[0058] In addition, it should also be noted that the preset angles are often two symmetrical angles. Therefore, each socket 700 needs to be subjected to two insertion tests, one at the positive preset angle and the other at the negative preset angle. Only when both angles are tested to be qualified is the socket 700 qualified. For example, when the preset angle is ±5°, the same batch of sockets 700 need to be subjected to the insertion test at +5° first and then at -5°. Only when both tests are qualified is the socket 700 a qualified product. Here, + and - both represent the angle offset directions.

[0059] It can be seen that by using the above socket test tooling, it is judged whether the socket 700 is qualified according to whether the plug 800 can be inserted into the socket 700 at the preset angle. That is, if the plug 800 can be successfully inserted at the preset angle, the socket 700 is qualified. If the plug 800 cannot be successfully inserted at the preset angle, the socket 700 is unqualified. Thus, the insertion test of the socket 700 can assist in eliminating unqualified sockets 700, which is beneficial to improving the user experience.

[0060] The following will make a detailed description of the angle adjustment mechanism 400, the plug fixing member 200, the socket fixture 100, and the driving mechanism 300 in the above structure respectively.

[0061] Figure 2 For Figure 1 the left view of the socket test tooling shown, as Figure 1 and Figure 2As shown, in a possible design, the socket test tool also includes a moving part 500, which is connected to the driving mechanism 300, and the plug fixing part 200 is connected to the moving part 500; the angle adjustment mechanism 400 includes a connecting part 410, a crimping part 420 and an adjustment groove 430 provided on the plug fixing part 200, the connecting part 410 passes through the plug fixing part 200 and is connected to the moving part 500, so that the plug fixing part 200 can rotate around the connecting part 410; the adjustment groove 430 is arranged along an arc trajectory with the connecting part 410 as the center of the circle, and the crimping part 420 is connected to the moving part 500 after passing through the adjustment groove 430, and when the crimping part 420 is tightened on the moving part 500, the end of the crimping part 420 is against the plug fixing part 200.

[0062] The moving part 500 is connected to the driving mechanism 300 and can be directly driven to move by the driving mechanism 300. The plug fixing part 200 is connected to the moving part 500, which is equivalent to being indirectly connected to the driving mechanism 300 through the moving part 500 and being driven to move by the driving mechanism 300.

[0063] The angle adjustment mechanism 400 is not only used for connecting the plug fixing part 200 and the movable part 500, but also for adjusting the angle of the plug fixing part 200 relative to the movable part 500. When the angle of the movable part 500 relative to the socket fixture 100 remains unchanged, adjusting the angle of the plug fixing part 200 relative to the movable part 500 is equivalent to adjusting the angle between the plug fixing part 200 and the socket fixture 100, thereby adjusting the angle between the socket 700 and the plug 800.

[0064] The connecting member 410 can be a common connecting bolt, pin, etc., and its main function is to initially position the plug fixing member 200 and the movable member 500. When the connecting member 410 passes through the plug fixing member 200 and is connected to the movable member 500, even if the crimping member 420 is loose, the plug fixing member 200 can maintain the connection with the movable member 500 and will not fall off the movable member 500.

[0065] In some embodiments, there may be a certain gap between the connector 410 and the plug fixture 200, that is, the plug fixture 200 is equivalent to being suspended on the movable member 500 through the connector 410, so that when the crimping member 420 is loose, the plug fixture 200 can rotate around the connector 410 even if the connector 410 is not operated.

[0066] In another embodiment, the connecting member 410 and the plug fixing member 200 are tightly matched, and when the crimping member 420 is loose, the connecting member 410 also needs to be loosened so that the plug fixing member 200 can rotate around the connecting member 410 .

[0067] The specific usage method of the above-mentioned angle adjustment mechanism 400 is as follows: When it is necessary to adjust the angle of the plug fixing member 200, loosen the crimping member 420 so that the crimping member 420 no longer presses tightly against the plug fixing member 200. Then, with the connecting member 410 as the center of the circle, rotate the plug fixing member 200. At this time, the crimping member 420 moves within the adjustment groove 430. When the plug fixing member 200 rotates to the set angle, tighten the crimping member 420 so that the crimping member 420 presses the plug fixing member 200 against the moving member 500, and the adjustment of the angle of the plug fixing member 200 can be completed, thereby realizing the adjustment of the angle between the plug 800 and the socket 700.

[0068] The above-mentioned angle adjustment mechanism 400 realizes the adjustment of the angle between the plug fixing member 200 and the socket fixture 100 by adjusting the plug fixing member 200, which is simpler to use and more convenient to operate.

[0069] In the above situation, it is also necessary to monitor the specific angle between the plug fixing member 200 and the socket fixture 100 so that the angle between the plug 800 and the socket 700 can be adjusted to the set angle relatively accurately through the angle adjustment mechanism 400.

[0070] As Figure 1 shown, in a possible design, the angle adjustment mechanism 400 further includes a first angle pointer 440 and a first angle scale 441. The first angle pointer 440 is connected to the plug fixing member 200, and the first angle scale 441 is fixed at the corresponding position of the first angle pointer 440. When adjusting the angle of the plug fixing member 200, the first angle pointer 440 swings relative to the first angle scale 441 to indicate the angle of the plug fixing member 200 relative to the socket fixture 100.

[0071] The corresponding position of the first angle pointer 440 refers to the position close to the swinging plane of the first angle pointer 440. The distance between the first angle scale 441 and the swinging plane of the first angle pointer 440 is not limited as long as it does not affect the reading of the personnel.

[0072] The fixed position of the first angle scale 441 can be any component with a fixed position on the socket test fixture, or other positions with fixed positions outside the socket test fixture. The embodiments of the present application do not limit this.

[0073] The first angle pointer 440 is connected to the plug fixing member 200. Therefore, when adjusting the angle of the plug fixing member 200, the first angle pointer 440 swings as the adjustment angle of the plug fixing member 200 changes. The swinging angle of the first angle pointer 440 on the first angle scale 441 is the rotation angle of the plug fixing member 200.

[0074] The above - described method of controlling the rotation angle of the plug fixing member 200 is that the first angle scale 441 remains stationary, and the first angle pointer 440 rotates with the plug fixing member 200. By the position indicated by the first angle pointer 440 on the first angle scale 441, the angle of the plug fixing member 200 can be known, so as to facilitate accurately adjusting the plug fixing member 200 to a preset angle.

[0075] In a possible design, the rotation angle of the plug fixing member 200 can also be controlled by the method that the first angle pointer 440 remains stationary and the first angle scale 441 rotates with the plug fixing member 200.

[0076] As Figure 1 shown, exemplarily, the angle adjustment mechanism 400 further includes a second angle pointer 450 and a second angle scale 451. The second angle pointer 450 is connected to the connecting member 410, and the second angle scale 451 is arranged on the plug fixing member 200 and is located at the corresponding position of the second angle pointer 450. When adjusting the angle of the plug fixing member 200, the second angle scale 451 swings relative to the second angle pointer 450 so that the second angle pointer 450 indicates the angle of the plug fixing member 200 relative to the socket fixture 100.

[0077] By this embodiment, the connecting member 410 is connected to the moving member 500 and does not rotate with the rotation of the plug fixing member 200. Therefore, connecting the second angle pointer 450 to the connecting member 410 can ensure that the second angle pointer 450 does not rotate with the plug fixing member 200. When the plug fixing member 200 rotates, the plug fixing member 200 drives the second angle scale 451 to rotate, so that the scale on the second angle scale 451 offsets a certain angle relative to the second angle pointer 450, thus facilitating accurately adjusting the plug fixing member 200 to a preset angle.

[0078] In a possible design, the related structures for indicating the angle can also be not provided, but instead an angle gauge is used to measure the initial angle and the adjusted angle between the socket fixture 100 and the plug fixing member 200, so as to control the included angle between the socket fixture 100 and the plug fixing member 200 within a set angle.

[0079] It can be understood that the above three methods for controlling the included angle between the socket fixture 100 and the plug fixing member 200 can be used alone or in any combination. When used in combination, multiple control methods can verify each other to improve the accuracy of angle control.

[0080] The following describes another structure of the angle adjustment mechanism 400.

[0081] Figure 3 This is a schematic structural diagram of a socket fixture and a base provided in an embodiment of the present application.Figure 4 for Figure 3 The socket fixture and the base are shown in a cross-sectional view cut from the plane where the axis of the abutment member is located. Figure 3 and Figure 4 As shown, in a possible design, the socket testing tool also includes a base 600, which is arranged below the socket fixture 100, and a first limit portion 610 and a second limit portion 620 are protruding from the base 600, and a portion of the socket fixture 100 is located between the first limit portion 610 and the second limit portion 620, and the angle between the base 600 and the socket fixture 100 can be adjusted.

[0082] In the above embodiment, optionally, the angle adjustment mechanism 400 includes abutment 460, which is connected to the first limiting portion 610, and one end of the abutment 460 passes through the first limiting portion 610 and abuts against the socket clamp 100 to press the socket clamp 100 against the second limiting portion 620.

[0083] Through this embodiment, when the angle of the base 600 relative to the plug fixing part 200 remains unchanged, the angle between the socket clamp 100 and the base 600 is adjusted, so as to achieve the effect of adjusting the angle between the socket clamp 100 and the fixing part of the plug 800, and further achieve the effect of adjusting the relative angle between the socket 700 and the plug 800.

[0084] After the angle of the socket fixture 100 relative to the base 600 is adjusted, the abutting member 460 is tightened so that the abutting member 460 presses the socket fixture 100 against the second limiting portion 620, thereby fixing the socket fixture 100 and the base 600 at a preset angle.

[0085] Please continue to refer to Figure 3 and Figure 4 In a possible design, the angle adjustment mechanism 400 also includes an inner cylindrical surface 470 and an outer cylindrical surface 480, and the central axis of the inner cylindrical surface 470, the central axis of the outer cylindrical surface 480, and the central axis of the abutment 460 are parallel; the inner cylindrical surface 470 is a surface of the base 600, and the outer cylindrical surface 480 is a surface of the socket fixture 100, and the inner cylindrical surface 470 is adapted to the outer cylindrical surface 480, and is used to adjust the angle between the socket fixture 100 and the base 600 when the inner cylindrical surface 470 and the outer cylindrical surface 480 are in contact.

[0086] The inner cylindrical surface 470 and the outer cylindrical surface 480 can both be part of or all of the entire outer circumference of the cylinder, depending on the angle range that usually needs to be adjusted. For example, the adjustment range of the socket clamp 100 is usually within 20°, so the inner cylindrical surface 470 and the outer cylindrical surface 480 can take any angle range greater than 20° of the outer circumference of the cylinder to meet the adjustment needs.

[0087] The inner cylindrical surface 470 can specifically be a surface on the first limiting portion 610 and / or the second limiting portion 620, or can also be a surface outside the first limiting portion 610 and the second limiting portion 620. The position of the outer cylindrical surface 480 corresponds to that of the inner cylindrical surface 470.

[0088] The inner cylindrical surface 470 being adapted to the outer cylindrical surface 480 means that the inner cylindrical surface 470 and the outer cylindrical surface 480 can be in a fitting state at any angle.

[0089] By making the central axes of the inner cylindrical surface 470, the outer cylindrical surface 480, and the abutting member 460 parallel, after the inner cylindrical surface 470 and the outer cylindrical surface 480 rotate relative to each other, when the socket fixture 100 is tightened by the abutting member 460, the tightening force will not affect the adjusted angle between the socket fixture 100 and the base 600, which is beneficial to ensuring the stability of the position of the socket fixture 100.

[0090] By providing the inner cylindrical surface 470 and the outer cylindrical surface 480, when adjusting the angle between the socket fixture 100 and the base 600, there is no need to pick up the socket fixture 100. Instead, the inner cylindrical surface 470 and the outer cylindrical surface 480 are always in contact, and the socket fixture 100 can be rotated in the contact state, which is labor-saving and more convenient to operate. In addition, since the inner cylindrical surface 470 and the outer cylindrical surface 480 are in surface contact at any angle, after the angle of the socket fixture 100 is fixed, when the plug 800 presses the socket 700, the socket fixture 100 can withstand a greater extrusion force and maintain the stability of the angle and position, and is not prone to deflecting the angle and generating displacement.

[0091] Figure 5 For Figure 3 the bottom view of the socket fixture and the base shown. As Figure 3 、 Figure 4 and Figure 5 shown, in a possible design, the base 600 includes a first base 630 and a second base 640. The second base 640 is located on the side of the first base 630 close to the socket fixture 100. A position adjusting mechanism 650 is provided between the first base 630 and the second base 640; the position adjusting mechanism 650 includes a longitudinal waist-shaped groove 651 provided on the first base 630, a transverse waist-shaped groove 652 provided on the second base 640, and a connecting bolt 653 passing through the longitudinal waist-shaped groove 651 and the transverse waist-shaped groove 652. The end of the connecting bolt 653 is connected with a nut 654. The nut 654 and the screw head of the connecting bolt 653 clamp the first base 630 and the second base 640, and when the nut 654 is loosened, the first base 630 and the second base 640 can move relative to each other along the direction of the longitudinal waist-shaped groove 651 or the transverse waist-shaped groove 652.

[0092] The second base 640 is located on the side of the first base 630 close to the socket fixture 100. Therefore, the socket fixture 100 is installed on the second base 640. Adjusting the position of the second base 640 is equivalent to adjusting the position of the socket fixture 100.

[0093] Considering that after the angle adjustment between the socket fixture 100 and the plug fixing member 200, there may be a situation where the plug 800 cannot be aligned with the socket hole on the socket 700. Therefore, by setting the above base 600 structure, when the plug 800 is not aligned with the socket hole on the socket 700, by moving the second base 640 along the horizontal waist-shaped groove 652 or the vertical waist-shaped groove 651, the socket 700 can be moved to a position where the socket hole is aligned with the plug 800, facilitating the insertion of the plug 800 into the socket 700.

[0094] The specific operation method is as follows: When it is necessary to adjust the position of the socket 700, loosen the nut 654, and move the first base 630 and the second base 640 relative to each other along the direction of the vertical waist-shaped groove 651 or the horizontal waist-shaped groove 652. Usually, the second base 640 is moved, so as to be able to adjust the relative position between the first base 630 and the second base 640, and further adjust the position of the socket fixture 100, so that it can be adjusted to adapt to the position of the plug 800 after the relative angle adjustment between the socket 700 and the plug 800, avoiding the situation where it is difficult to insert the plug 800 and the socket hole on the socket 700 due to misalignment.

[0095] As Figure 1 and Figure 2 shown, in a possible design, the plug fixing member 200 includes a first fixing member 210 and a second fixing member 220. The second fixing member 220 is detachably connected to the first fixing member 210. The first fixing member 210 is drivingly connected to the driving mechanism 300, and the plug 800 is arranged on the second fixing member 220.

[0096] When testing sockets 700 of different specifications, different models of plugs 800 need to be replaced. At this time, only the second fixing member 220 can be removed, and the second fixing member 220 with another model of plug 800 can be installed on the first fixing member 210 to achieve the replacement of the plug 800, without the need to disassemble and replace the plug fixing member 200 as a whole, saving time and processes and reducing costs.

[0097] Among them, the detachable structure between the first fixing member 210 and the second fixing member 220 can be various, for example, plug connection, screw connection, snap connection, crimping, etc.

[0098] Exemplarily, in some embodiments, the first fixing member 210 is provided with a clamping groove, the second fixing member 220 is clamped in the clamping groove, a plurality of screw holes are arranged outside the clamping groove, and screws are threadedly connected in the screw holes. When the screws are tightened in the screw holes, the ends of the screws press against the second fixing member 220 and press the second fixing member 220 towards the bottom of the clamping groove, so that a stable fit is maintained between the second fixing member 220 and the first fixing member 210. When replacing the plug 800, loosen the screws, remove the second fixing member 220 from the clamping groove, and then replace it with the second fixing member 220 equipped with another type of plug 800.

[0099] As Figure 3 shown, in a possible design, the socket fixture 100 includes a bottom wall 110, a fixed wall 120, a movable wall 130, a connecting wall 140, and a first screw 150. The fixed wall 120 and the connecting wall 140 are connected to one side of the bottom wall 110 facing the plug fixing member 200. The movable wall 130 is arranged between the fixed wall 120 and the connecting wall 140. The first screw 150 is threadedly connected to the connecting wall 140, and one end of the first screw 150 is rotatably connected to the movable wall 130. When the first screw 150 rotates in the first direction, the first screw 150 drives the movable wall 130 to move towards the fixed wall 120 to clamp the socket 700. When the first screw 150 rotates in the second direction, the first screw 150 drives the movable wall 130 to move away from the fixed wall 120 to loosen the socket 700.

[0100] The first direction and the second direction refer to two opposite rotation directions. According to the thread helix direction of the first screw 150 and the resulting axial movement effect of the first screw 150, the first direction can be the clockwise direction or the counterclockwise direction. Correspondingly, the second direction is opposite to the first direction.

[0101] In the above embodiment of the socket fixture 100, by rotating the first screw 150 in the first direction, the first screw 150 can rotate relative to the connecting wall 140, gradually approach the fixed wall 120, and push the movable wall 130 towards the fixed wall 120. Placing the socket 700 to be tested between the fixed wall 120 and the movable wall 130 can clamp the socket 700 by the movable wall 130 and the movable wall 130.

[0102] When a socket 700 is tested, it is necessary to remove the socket 700 from the socket fixture 100. At this time, rotate the first screw 150 in the second direction, so that the first screw 150 rotates relative to the connecting wall 140 and gradually moves away from the fixed wall 120. Driven by the first screw 150, the movable wall 130 moves away from the fixed wall 120, thereby loosening the socket 700, and then the personnel can remove the socket 700.

[0103] It can be understood that in actual production, there may be certain dimensional errors in each socket 700, and the qualification status of each socket 700 is random. Therefore, in order to avoid damaging the socket 700 during the process of clamping the socket 700 and ensure the test accuracy of the socket 700, the rotation of the first screw 150 can be manually controlled by a person. For example, a handle is provided at one end of the first screw 150 to facilitate the person to rotate the first screw 150 through the handle.

[0104] The above socket fixture 100 has a simple structure and is convenient to operate, and is suitable for batch testing of sockets 700.

[0105] Such as Figure 1 and Figure 2 As shown in, in a possible design, the driving mechanism 300 includes a second screw 310, a guide post 320 and a slider 330. The guide post 320 and the second screw 310 are parallel to the direction in which the plug fixing member 200 and the socket fixture 100 are oppositely arranged. The slider 330 is disposed through the guide post 320 and the second screw 310 and is threadedly connected to the second screw 310. The slider 330 is connected to the plug fixing member 200. When the second screw 310 is rotated in the third direction, the second screw 310 drives the slider 330 to move along the guide post 320 in a direction close to the socket fixture 100 to insert the plug 800 into the socket 700; when the second screw 310 is rotated in the fourth direction, the second screw 310 drives the slider 330 to move along the guide post 320 in a direction away from the socket fixture 100 to pull the plug 800 out of the socket 700.

[0106] The third direction and the fourth direction refer to two opposite rotation directions. According to the thread helix direction of the second screw 310 and the different moving effects of the slider 330 along the axis of the guide post 320, the third direction can be the clockwise direction or the counterclockwise direction. Correspondingly, the fourth direction is opposite to the first direction.

[0107] The guide post 320 is a smooth columnar structure, which can be a cylinder or a prism. A guide sleeve can be provided in the hole on the slider 330 to reduce the friction force of the slider 330 sliding relative to the guide post 320.

[0108] The setting of the guide post 320 can prevent the slider 330 from rotating along with the second screw 310 when the second screw 310 rotates, so as to ensure that the rotation of the second screw 310 can only make the slider 330 move along the axis direction of the guide post 320.

[0109] The slider 330 is connected to the plug fixing member 200, so that the plug fixing member 200 can move following the movement of the slider 330. It can be understood that the slider 330 can be directly connected to the plug fixing member 200 or indirectly connected to the plug fixing member 200. For example, in the case where the socket testing tooling further includes a moving member 500, the indirect connection can be that the plug fixing member 200 is connected to the moving member 500, and the moving member 500 is connected to the slider 330, thereby realizing the indirect connection between the connection block of the plug 800 and the slider 330.

[0110] In order to facilitate taking timely treatment measures according to the different qualification situations of each socket 700 without damaging the structure of the socket 700, the second screw 310 can be manually driven. For example, a handwheel can be provided at the end of the second screw 310, and a person drives the second screw 310 to rotate by rotating the handwheel, so as to drive the plug fixing member 200 to approach or move away from the socket fixture 100. During the process of inserting the plug 800 into the socket 700, according to the different resistances received by the rotation of the handwheel, it can be timely judged whether the plug 800 can be smoothly inserted into the socket 700. When the plug 800 cannot be inserted into the socket 700, the rotation of the handwheel along the third direction can be timely stopped, and the unqualified socket 700 can be removed for treatment, thus facilitating controlling the process of the test according to the hand feeling.

[0111] It can be seen that in the above embodiments, by rotating the second screw 310, the slider 330 can be driven to move, and then the slider 330 drives the plug fixing member 200 to move, finally achieving the purpose of inserting the plug 800 into the socket 700 or pulling the plug 800 out of the socket 700. Moreover, the operation mode of the above driving mechanism 300 is simple, the moving distance of driving the plug 800 is accurate, and it can start and pause at any time, which is convenient for control.

[0112] In summary, for a socket testing tooling provided by the present application, when in use, the socket 700 to be tested can be clamped on the socket fixture 100, and then by operating the driving mechanism 300, the driving mechanism 300 drives the plug fixing member 200 to approach the socket fixture 100, so as to insert the plug 800 into the socket 700. Among them, the angle adjusting mechanism 400 can adjust the angle between the plug fixing member 200 and the socket fixture 100 to a preset angle. When the plug 800 can be inserted into the socket 700 at the preset angle, generally the plug 800 can also be inserted into the socket 700 in the direction directly opposite to the socket 700. Therefore, by using the above socket testing tooling, it is judged whether the socket 700 is qualified according to whether the plug 800 can be inserted into the socket 700 at the preset angle, that is, if the plug 800 can be smoothly inserted at the preset angle, the socket 700 is qualified; if the plug 800 cannot be smoothly inserted at the preset angle, the socket 700 is unqualified. Thus, by performing an insertion test on the socket 700, unqualified sockets 700 can be assisted in being eliminated, which is beneficial to improving the user experience.
