Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component programming technology, and in particular to a programming fixture. Background Technology
[0002] A smart module for LED (Light Emitting Diode) displays is a display component that integrates advanced technology and intelligent functions. It is an upgrade and innovation based on traditional LED display modules, and has functions such as automatic adjustment, intelligent monitoring and management. For example, it can realize intelligent functions such as automatic brightness adjustment, dynamic energy saving, automatic display effect optimization, data storage and automatic correction. These modules usually integrate high-end MCU (Microcontroller Unit) control chips. After the PCB (Printed Circuit Board) is surface-mounted, the MCU chip in the semi-finished PCBA (Printed Circuit Board Assembly) needs to be programmed.
[0003] Currently, during PCB surface mount soldering, programming sockets are pre-soldered at the programming locations, and then the programmer's programming plug is connected to the programming socket for programming. However, this method of programming is problematic because the terminals of the programming sockets are not heat-resistant and cannot be reflow soldered. Therefore, manual soldering is typically used, which is not only labor-intensive and wasteful of solder, but also requires soldering a dedicated programming socket for each PCB, resulting in excessive material consumption and increased costs. Utility Model Content
[0004] The purpose of this invention is to provide a programming jig that is easy to operate, simple to use, and reusable.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of this application, a programming jig is provided, comprising: A base with a support position for accommodating the structural component to be programmed; A support frame, which is rotatably mounted on the base; A programming mechanism includes a programmer and a programming element, the programmer and the programming element being electrically connected, the programming element being arranged on the support frame; The support frame can rotate relative to the base, thereby moving the programming component away from the support position, or moving the programming component closer to and abutting the signal contact on the structural component to be programmed arranged on the support position, so that the programming component and the signal contact make electrical contact.
[0006] In some embodiments, the support frame includes a support member and a connector. The support member is rotatably mounted on the base, and the connector is connected to the end of the support member away from the base. The programming component is disposed on the connector. The support member rotates relative to the base, and the connector follows the support member, allowing the connector to move closer to the bearing position so that the programming component can abut against the signal contact on the structural component to be programmed in the bearing position.
[0007] In some embodiments, the connector is movably connected to the support, and the connector is movable relative to the support, so that the programmer moves relatively closer to or further away from the support, thereby making the position of the programmer relative to the support adjustable.
[0008] In some embodiments, the support member includes a support arm and a load-bearing arm, the support arm being rotatably connected to the base, and the load-bearing arm being connected to the end of the support arm away from the base; the end opening of the load-bearing arm opposite to the support arm forms a receiving groove, and the connector is at least partially received within the receiving groove and slidably engaged with the load-bearing arm, so that the connector can move relative to the support member; and / or, The support frame also includes a locking member, which is movably disposed on the bearing arm. The locking member is located on the outside of the connector. The locking member can be relatively close to and abut against the outside of the connector to achieve relative fixation of the connector and the bearing arm. Alternatively, the locking member can be relatively far away from the connector to release the abutment against the connector.
[0009] In some embodiments, the programming fixture further includes a mounting member disposed on the base and located on one side of the bearing position. The support member is rotatably connected to the base via the mounting member, allowing the support member to rotate upward relative to the base to move the programming component away from the bearing position, or to rotate downward to move the programming component closer to the bearing position.
[0010] In some embodiments, one side opening of the base forms a mounting groove, and the mounting member is rotatably arranged within the mounting groove; The burning fixture also includes two bearings, and each end of the mounting component is fitted with a bearing. The mounting component is rotatably connected to the base through the bearings.
[0011] In some embodiments, the support member is movably connected to the mounting member, and the support member is movable relative to the mounting member along the extension direction of the mounting member.
[0012] In some embodiments, the support member is sleeved on the mounting member and slides in cooperation with the mounting member; The programming fixture also includes a limiting member, which is movably disposed on the support member. The limiting member is located outside the mounting member and can be relatively close to and abut against the outside of the mounting member, so that the support member is fixed at a set position on the mounting member.
[0013] In some embodiments, the programming element includes a housing and a probe, the housing being fixed to the connector; the probe is disposed on the side of the housing opposite to the connector; The programming mechanism also includes signal lines, and the probe is electrically connected to the programmer via the signal lines.
[0014] In some embodiments, the probe includes a main body and a needle body. The main body extends into the housing at one end away from the support member and is fixedly connected to the housing. The needle body extends into the main body at one end away from the housing and is movably connected to the housing. The needle body is movable relative to the main body along the extending direction of the main body. The probe also includes an elastomer disposed within the main body portion. The opposite ends of the elastomer are fixed to the main body portion and the needle body portion, respectively. The elastomer can extend and retract as the needle body portion moves.
[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this invention, the support frame is rotatably mounted on the base, allowing it to rotate relative to the base. This movement moves the programming component arranged on the support frame, bringing it closer to the support position and abutting against the signal contacts on the structural component to be programmed. This enables the programming component to make electrical contact with the signal contacts, establishing an electrical connection between the programmer and the structural component to be programmed. The programmer can then transmit signals to the structural component, thus programming the component. This design is convenient, simple, time-saving, and labor-saving, while improving work efficiency. Furthermore, the rotation of the support frame can move the programming component away from the support position, breaking the contact between the programming component and the signal contacts. This design also prevents the support frame from interfering with the replacement of structural components. Specifically, it allows for easy removal of the programmed structural component from the support position, and the placement of another structural component to be programmed at the support position for programming as needed. This facilitates the reuse of the programming fixture, reduces material consumption, and saves costs. Attached Figure Description

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] This application provides a programming fixture for programming structural components.
[0025] For example, the structural component can be a semi-finished PCBA (Printed Circuit Board Assembly) obtained through surface mount soldering. The structural component includes a PCB, a chip, and LEDs. The chip and LEDs are located on opposite sides of the PCB and are electrically connected to circuitry on the PCB. Signal contacts are also provided on the sides of the PCB, and these contacts are electrically connected to the chip via circuitry on the PCB. The signal contacts and the chip are located on the same side of the PCB. Multiple signal contacts can be provided, spaced apart on the sides of the PCB.
[0026] The following detailed description, in conjunction with the accompanying drawings, provides specific embodiments of the programming fixture of this application.
[0027] Figure 1 This is a schematic diagram of the structure of the programming fixture 100 in this embodiment. Figure 2 This is a schematic diagram of the programming jig 100 that carries the structural component 200 in this embodiment. Figure 3 This is a schematic diagram illustrating the effect of the burning fixture 100 in this embodiment.
[0028] refer to Figures 1-3 The programming fixture 100 includes a base 1, a support frame 2, and a programming mechanism 3. The base 1 has a bearing position 11 for accommodating the structural component 200 to be programmed. The support frame 2 is rotatably mounted on the base 1. The programming mechanism 3 includes a programmer 31 and a programming component 32, which are electrically connected. The programming component 32 is arranged on the support frame 2. The support frame 2 can rotate relative to the base 1, thereby moving the programming component 32 away from the bearing position 11, or moving the programming component 32 closer to and abutting against the signal contact 210 on the structural component 200 to be programmed, arranged on the bearing position 11, so that the programming component 32 and the signal contact 210 make electrical contact.
[0029] In this application, since the support frame 2 is rotatably mounted on the base 1, the support frame 2 can rotate relative to the base 1, thereby driving the programming component 32 arranged on the support frame 2 to move. This allows the programming component 32 to approach the bearing position 11, align with and abut against the signal contact 210 on the structural component 200 to be programmed, which is arranged at the bearing position 11. This enables the programming component 32 to make electrical contact with the signal contact 210, thereby achieving electrical connection between the programmer 31 and the structural component 200 to be programmed. This allows the programmer 31 to transmit signals to the structural component 200 to be programmed, thus achieving programming of the structural component 200. Compared with the prior art, the above design does not require additional pre-soldering of programming sockets, making operation convenient and simple, saving time and effort, and improving work efficiency. Furthermore, the rotation of the support frame 2 can also move the programming component 32 away from the bearing position 11, thereby disconnecting the programming component 32 from the signal contact 210. At this time, the above design can also avoid the support frame 2 interfering with the replacement operation of the structural component 200. That is, it is convenient to remove the completed programming structural component 200 from the bearing position 11, and fix another structural component 200 to be programmed at the bearing position 11 as needed for programming operation. This is conducive to the reuse of the programming fixture 100, reducing material consumption and saving costs.
[0030] In this embodiment, a groove with a top opening is formed on the base 1. This groove is the bearing position 11, which is used to accommodate the structural component 200 to be programmed. The structural component 200 to be programmed is placed at the bearing position 11 with the LED beads facing down and the signal contacts 210 facing up.
[0031] The cross-sectional area of the groove is greater than or equal to the cross-sectional area of the outer contour of the structural component 200, which facilitates the handling of the structural component 200.
[0032] In this embodiment, the base 1 has a rectangular cross-section. The base 1 has an opening on at least one side along the circumference, which communicates with the groove, facilitating the placement and removal of the structural component 200.
[0033] In this embodiment, the base 1 is made of bakelite material, which gives the base 1 high mechanical strength and good insulation properties, thus isolating electrical conduction and improving the safety of the burning operation.
[0034] In some embodiments, the base 1 has at least one group of positioning holes corresponding to each side. Each group of positioning holes includes a plurality of positioning holes spaced apart. The arrangement direction of the plurality of positioning holes in each group of positioning holes is perpendicular to the corresponding side of the base 1. A positioning pin is inserted into one of the positioning holes in each group of positioning holes. The positioning pin is used to abut against the outer side of the structural component 200 to be burned. All the positioning pins can cooperate to position the structural component 200 to be burned in the circumferential direction to prevent the structural component 200 from shifting during the burning process. Furthermore, by changing the position of the positioning pins, the size of the space enclosed by all the positioning pins can be expanded or reduced, thereby adapting to structural components 200 of various sizes and improving the versatility of the burning fixture 100.
[0035] Alternatively, the positioning hole group may include a positioning hole, in which case the length direction of the positioning hole extends along the direction perpendicular to the side of the corresponding base 1, and the positioning pin is inserted into the positioning hole. By changing the position of the positioning pin in the positioning hole, the size of the space enclosed by all the positioning pins can be expanded or reduced, thereby adapting to structural parts 200 of various sizes, which is beneficial to improving the versatility of the burning jig 100.
[0036] The support frame 2 is rotatably mounted on the base 1 and is capable of rotating relative to the base 1. The support frame 2 includes a support member 21 and a connecting member 22. The support member 21 is rotatably mounted on the base 1.
[0037] Figure 4 This is a side view of the burning fixture 100 in this embodiment.
[0038] refer to Figures 1-4 Optionally, the burning fixture 100 also includes a mounting member 4, which is arranged on the base 1 and located on one side of the bearing position 11. The support member 21 is rotatably connected to the base 1 through the mounting member 4 so that the support member 21 can rotate relative to the base 1.
[0039] For example, one side opening of the base 1 forms a mounting groove, and the mounting groove opens at the top of the base 1, located on one side of the bearing position 11. It should be noted that the side opening of the mounting groove is adjacent to or opposite to the side opening of the recess. The mounting member 4 is arranged within the mounting groove, and its opposite ends are rotatably connected to the base 1. The extending direction of the mounting member 4 is perpendicular to the opening direction of the mounting groove. That is, the mounting member 4 is arranged horizontally, allowing the support member 21 to rotate upwards or downwards relative to the base 1. In this case, the mounting groove prevents the base 1 from interfering with the rotation of the support frame 2.
[0040] Specifically, the base 1 has receiving grooves formed on opposite sides of the mounting groove. The two receiving grooves open on opposite sides and communicate with the mounting groove. The opposite ends of the mounting member 4 extend into the two receiving grooves and are rotatably connected to the base 1.
[0041] Optionally, the bottom wall of the mounting groove is recessed downward to form a stepped structure 12, which is located below the mounting member 4. The side walls of the stepped structure 12 are spaced apart on the side of the mounting member 4 facing the bearing position 11, and the bottom wall of the stepped structure 12 is spaced apart below the mounting member 4. The side walls and bottom wall of the stepped structure 12 are used to abut against the support member 21, thereby limiting the rotation angle of the support member 21 when it is lifted upward. This ensures that the support frame 2 does not interfere with the handling of the structural member 200, while also preventing the support member 21 from over-rotating. At the same time, the stepped structure 12 also provides space for the rotation of the support member 21 to avoid interfering with the normal rotation of the support frame 2.
[0042] Optionally, the programming fixture 100 also includes two bearings 5, with one bearing 5 fitted at each end of the mounting member 4, and the mounting member 4 rotatably connected to the base 1 via the bearings 5. The bearings 5 can improve the stability and smoothness of the rotation of the mounting member 4. Specifically, the two bearings 5 are arranged one-to-one in the two receiving slots.
[0043] The bearing 5 can be a ball bearing, roller bearing, or similar type. For example, the bearing 5 includes an inner ring, an outer ring, and multiple rolling elements. The outer ring is spaced around the outer circumference of the inner ring, and the multiple rolling elements are arranged spaced apart or adjacently between the outer and inner rings. Each rolling element can roll, allowing the inner and outer rings to rotate relative to each other. The inner ring is fitted onto and fixedly connected to the mounting member 4, while the outer ring is fixed to the base 1. The rolling elements reduce the frictional resistance between the inner and outer rings, thereby improving the smoothness, flexibility, and stability of the rotation of the mounting member 4 relative to the base 1.
[0044] In some embodiments, the programming fixture 100 may further include a locking member. Exemplarily, at least one end of the mounting member 4 is provided with a locking member, which is movably disposed on the mounting member 4 and can move relative to the mounting member 4 along its extending direction. Taking the example of a locking member being provided at one end of the mounting member 4, a locking hole is provided on the side of the base 1 near the locking member. The locking hole and the receiving groove are spaced apart. The locking member can move relative to the mounting member 4 along its extending direction and extend into the locking hole to restrict the rotation of the mounting member 4 relative to the base 1, thereby fixing the support frame 2 in a preset position (the position of the support frame 2 during programming) to prevent the support frame 2 from shaking during programming, thus improving the stability of the support frame 2 and ensuring normal programming operation.
[0045] In this embodiment, optionally, the support member 21 is movably connected to the mounting member 4, and the support member 21 can move relative to the mounting member 4 along the extension direction of the mounting member 4, so that the position of the support member 21 relative to the mounting member 4 can be adjusted.
[0046] For example, the support member 21 is sleeved on the mounting member 4 and slides in engagement with the mounting member 4. In other embodiments, the support member 21 and the mounting member 4 may also achieve a sliding engagement in other forms. For example, the mounting member 4 may have a groove with an opening on one side, and the support member 21 may have a slider that is accommodated in the groove and slides in engagement with the groove.
[0047] Optionally, the burning fixture 100 also includes a limiting member 6, which is movably disposed on the support member 21. The limiting member 6 is located outside the mounting member 4 and can be relatively close to and abut against the outside of the mounting member 4, so that the support member 21 can be fixed at a set position (depending on actual needs) on the mounting member 4, ensuring that the support member 21 and the mounting member 4 are in a relatively fixed state, so as to avoid the support member 21 moving relative to the mounting member 4 during operation and affecting the stability of the support frame 2; or, the limiting member 6 can be relatively away from the mounting member 4 to release the mounting member 4, so as to facilitate the movement of the mounting member 4.
[0048] The limiting member 6 can be made of screws, which move relative to the support member 21 through the action of threads. Furthermore, the threads can also achieve the screw connection and fixation between the limiting member 6 and the support member 21. When the limiting member 6 abuts against the mounting member 4, the position of the limiting member 6 relative to the support member 21 is fixed, thereby ensuring that the limiting member 6 can maintain the state of abutting against the mounting member 4, which can improve the limiting effect of the limiting member 6 and ensure that the support member 21 remains fixed in the set position on the mounting member 4, thus improving the stability of the support frame 2.
[0049] In other embodiments, the mounting component 4 can be omitted. In this case, the lower end of the support component 21 extends into the base 1 and is rotatably connected to the base 1. Based on the lower end of the support component 21, it can rotate counterclockwise or clockwise relative to the base 1 in the horizontal plane, making the position of the support component 21 relative to the base 1 adjustable. This facilitates rotating the support component 21 to a preset position, enabling the programming of different models of structural components 200 and different positions. Optionally, a bearing 5 is fitted onto the lower end of the support component 21, and the support component 21 is rotatably connected to the base 1 via the bearing 5, wherein the axis of the bearing 5 extends vertically.
[0050] refer to Figures 1-4 In this embodiment, the support member 21 includes a support arm 211 and a load-bearing arm 212.
[0051] The support arm 211 is rotatably connected to the base 1. Specifically, the support arm 211 is sleeved on the mounting part 4 and is rotatably connected to the base 1 through the mounting part 4. At this time, the limiting part 6 is provided on the support arm 211.
[0052] The support arm 212 is connected to the end of the support arm 211 away from the base 1. Specifically, the support arm 212 is located on the side of the support arm 211 away from the base 1. That is, an angle is formed between the support arm 212 and the support arm 211, which can be a right angle. Furthermore, the support arm 211, the support arm 212, and the mounting member 4 are perpendicular to each other. This design allows the support arm 212 to rotate with the support arm 211 to be positioned above the support position 11 along a vertical interval. In other embodiments, the angle can also be an acute angle.
[0053] The connector 22 is connected to the end of the support 21 away from the base 1. When the support 21 rotates relative to the base 1, the connector 22 can move with the support 21, allowing the connector 22 to move closer to the bearing position 11. Specifically, the connector 22 is connected to the bearing arm 212, and the connector 22 is located at the end of the bearing arm 212 away from the support arm 211. The connector 22 can rotate upward relative to the base 1 with the support 21 to move away from the bearing position 11, or rotate downward to a position above the bearing position 11.
[0054] Optionally, the connector 22 is movably connected to the support 21, and the connector 22 is movable relative to the support 21. Specifically, the end opening of the bearing arm 212 opposite to the support arm 211 forms a receiving groove, and the connector 22 is at least partially received in the receiving groove and slides with the bearing arm 212, so that the connector 22 can slide relative to the support 21 along the extending direction of the bearing arm 212, thereby lengthening or shortening the combined length of the connector 22 and the bearing arm 212.
[0055] Optionally, the support frame 2 also includes a locking member 7. The locking member 7 is movably disposed on the bearing arm 212. The locking member 7 is located on the outside of the connector 22. The locking member 7 can be relatively close to and abut against the outside of the connector 22 to achieve relative fixation between the connector 22 and the bearing arm 212, so as to prevent the connector 22 from moving relative to the bearing arm 212 during operation and affecting the stability of the support frame 2; or, the locking member 7 can be relatively away from the connector 22 to release the abutment against the connector 22, so as to facilitate the movement of the connector 22.
[0056] The locking element 7 can be made of screws, which move relative to the bearing arm 212 through the action of threads. Furthermore, the threads can also achieve the screw connection and fixation between the locking element 7 and the bearing arm 212. When the locking element 7 abuts against the connecting element 22, the position of the locking element 7 relative to the bearing arm 212 is fixed, thereby ensuring that the locking element 7 can maintain the state of abutting against the connecting element 22 and improving the locking effect of the locking element 7.
[0057] In this embodiment, the programming mechanism 3 includes a programmer 31 and a programming element 32, which are electrically connected. The programming element 32 is arranged on the support frame 2. The programming element 32 can rotate with the support frame 2 relative to the base 1 to approach the bearing position 11 and align with and abut against the signal contact 210 on the structural component 200 to be programmed, which is located at the bearing position 11. This allows the programming element 32 to make electrical contact with the signal contact 210, thus establishing an electrical connection between the programmer 31 and the structural component 200 to be programmed. This enables the programmer 31 to transmit signals to the structural component 200, thereby achieving programming of the structural component 200. The operation is convenient, simple, time-saving, and labor-saving. The position of the support frame 2 when the programming element 32 abuts against the signal contact 210 is the preset position mentioned above (the position of the support frame 2 during programming).
[0058] Specifically, the programming component 32 is mounted on the connector 22. When the support 21 rotates relative to the base 1, the connector 22 moves with the support 21, allowing the connector 22 to move closer to the bearing position 11. This enables the programming component 32 to be positioned above the structural member 200 located at the bearing position 11 and to come into contact with the signal contact 210, thus achieving electrical connection. Furthermore, under the combined forces of gravity of the support frame 2 and the programming component 32, as well as the counter-supporting force of the structural member 200 on the programming component 32, the support frame 2 and the programming component 32 can achieve a balanced state, pressing the programming component 32 firmly onto the signal contact 210. Moreover, without external force, the support frame 2 does not tend to rotate freely relative to the base 1, thus improving the stability of the support frame 2. This ensures that the programming component 32 maintains electrical contact with the signal contact 210 during the programming process, which is beneficial for ensuring the continuity of signal transmission. Furthermore, the connector 22 can move with the support 21 so that the programming component 32 can move away from or closer to the support 21, thereby making the position of the programming component 32 relative to the support 21 adjustable in the extension direction of the connector 22. Since the support 21 can move relative to the mounting component 4, the position of the programming component 32 in the extension direction of the mounting component 4 can also be adjusted. Moreover, since the mounting component 4, the support arm 211 and the bearing arm 212 are perpendicular to each other, the connector 22 and the mounting component 4 are perpendicular to each other. That is, the above design can make the position of the programming component 32 adjustable in two mutually perpendicular directions, thereby adapting to programming at different positions on the structural component 200, which is beneficial to improving the versatility of the programming fixture 100.
[0059] The programming component 32 includes a housing 321 and a probe 322. The housing 321 is fixed to the connector 22, and the probe 322 is located on the side of the housing 321 opposite to the connector 22.
[0060] The number of probes 322 can be multiple, and multiple probes 322 are spaced apart on the housing 321. The multiple probes 322 are arranged in a one-to-one correspondence with multiple signal contacts 210.
[0061] For example, the probe 322 includes a main body 3221 and a needle body 3222. The main body 3221 extends into the end of the housing 321 away from the support member 21 and is fixedly connected to the housing 321. The needle body 3222 extends into the end of the main body 3221 away from the housing 321 and is movably connected to the housing 321. The needle body 3222 can move relative to the main body 3221 along the extending direction of the main body 3221. This allows the length of the probe 322 to be extended or shortened, making the length of the probe 322 adjustable. This adapts to the programming of structural components 200 of different thicknesses, which is beneficial to improving the versatility of the programming fixture 100. At the same time, the above design can also avoid excessive stress at the contact position between the probe 322 and the signal contact 210, thereby reducing the risk of damage to the probe 322 and the signal contact 210.
[0062] Optionally, the probe 322 also includes an elastic body disposed within the main body 3221. The opposite ends of the elastic body are fixed to the main body 3221 and the needle body 3222, respectively. The elastic body can extend and retract as the needle body 3222 moves. The elastic body provides elastic support for the needle body 3222. When the needle body 3222 abuts against the signal contact 210, the connector 22 applies a downward force to the probe 322, causing relative movement between the needle body 3222 and the main body 3221. This reduces the length of the probe 322, causing it to retract. At this time, the elastic body deforms due to external compression and accumulates elastic potential energy. After the force on the probe 322 reaches equilibrium, the elastic body applies a downward force to the needle body 3222 to restore its deformation. This ensures that the needle body 3222 maintains electrical contact with the signal contact 210 during the programming process, which helps guarantee the continuity of signal transmission. After the probe 322 moves away from the signal contact 210 as the support frame 2 rotates, the elastomer recovers its deformation and releases elastic potential energy due to the removal of the external force. Under the action of this elastic potential energy, the needle body 3222 can move relative to the main body 3221 so that the needle body 3222 moves away from the connector 22 and resets, so as to facilitate subsequent burning operations.
[0063] Specifically, the elastomer can be a spring. In other embodiments, the elastomer can also be other elastic structures.
[0064] In this embodiment, the programming mechanism 3 further includes a signal line 33, through which the probe 322 is electrically connected to the programmer 31. Exemplarily, one end of the signal line 33 is electrically connected to the programmer 31, and the other end extends to the housing 321 and into its interior to be electrically connected to the probe 322. This protects the connection between the signal line 33 and the probe 322, preventing leakage, electric shock, and other accidents, thus ensuring the safety of the programming process.
[0065] It should be noted that this application does not improve the programmer 31. Its structure and working principle can be based on existing technology, and will not be described in detail here.
[0066] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the support frame is rotatably mounted on the base, allowing it to rotate relative to the base. This movement moves the programming component arranged on the support frame, bringing it closer to the support position to align with and abut against the signal contacts on the structural component to be programmed. This enables the programming component to make electrical contact with the signal contacts, establishing an electrical connection between the programmer and the structural component to be programmed. The programmer can then transmit signals to the structural component, thus enabling programming. This process is convenient, simple, time-saving, and labor-saving. Furthermore, the rotation of the support frame can move the programming component away from the support position, breaking the contact between the programming component and the signal contacts. This design also prevents the support frame from interfering with the replacement of structural components. Specifically, it allows for easy removal of the programmed structural component from the support position, and the placement of another structural component to be programmed at the support position for programming as needed. This facilitates the reuse of the programming fixture, reduces material consumption, and saves costs.
[0067] Furthermore, since the connector and support are movably connected, the programmable component arranged on the connector can move with the connector, allowing the programmable component to move away from or towards the support, thus achieving positional adjustability of the programmable component in the extension direction of the connector. Also, since the support and mounting are movably connected, the support can move relative to the mounting along the extension direction of the mounting, thereby moving the programmable component in the extension direction of the mounting. Because the mounting, support arm, and load-bearing arm are mutually perpendicular, the connector and mounting are also mutually perpendicular. That is, the above design allows for positional adjustability of the programmable component in two mutually perpendicular directions, thus adapting to programming at different positions on the structural components and improving the versatility of the programming fixture.
[0068] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
