[0023] As Figure 1 - Figure 2 shown, an embodiment of the present utility model provides a portable software burning jig, which includes a burner 1, a burning socket 2, a pin 3, and a connecting wire 4. Among them, the pin 3 is arranged on the burner 1, and the connecting wire 4 is used to connect the pin 3 and the burning socket 2, that is, the burner 1 and the burning socket 2 are electrically connected through the pin 3 and the connecting wire 4. Chip burning is the process of writing a program into a flash chip through the burner 1. In the traditional method, the flash chip needs to be placed on the burning socket 2 for connection during burning to achieve the burning of the flash chip.

[0024] In this embodiment, the programming socket 2 is set as a separately movable module, and the pin header 3 on the programmer 1 is set in a 2*8 specification, and is connected to the programming socket 2 through a 2*8 matching connecting wire 4. Therefore, the programming socket 2 can be directly connected to the flash chip on the PCB board without removing the flash chip from the PCB board.

[0025] In this embodiment, the programming socket 2 is provided with ejector pins 5, and the software is programmed by contacting the flash chip on the PCB board through the ejector pins 5, and the number of ejector pins 5 protruding can be switched to achieve the purpose of being compatible with multiple package programming. Generally speaking, the package programming is mainly for two types, SOP8 and SOP16. Therefore, the ejector pins 5 on the programming socket 2 are also mainly set for programming of SOP8 and SOP16 packages.

[0026] In a specific implementation manner of this embodiment, two groups of ejector pins 5 are provided on the programming socket 2. One group is in a 2*4 specification, corresponding to SOP8 package programming; the other group is in a 2*8 specification, corresponding to SOP16 package programming. When programming the SOP8 package is required, the 2*4 specification ejector pins 5 on the programming socket 2 are inserted into the corresponding pin positions of the flash chip, and the programmer 1 transmits the programming signal to the programming socket 2, and finally transmits it to the pins of the flash chip, thereby completing the programming of the flash chip. Similarly, when programming the SOP16 package is required, the 2*8 specification ejector pins 5 on the programming socket 2 are inserted into the corresponding pin positions of the flash chip.

[0027] Considering setting the size of the programming socket 2 as small as possible, and at the same time avoiding the other ejector pins 5 being obstructed by other positions on the PCB board when programming a flash chip of one specification. As an optional implementation manner, in this embodiment, the 2*4 specification ejector pins 5 are set in the middle of the panel of the programming socket 2 and are distributed in two rows on the left and right as shown in the figure, and the 2*8 specification ejector pins 5 are located in the upper and lower parts of the panel of the programming socket 2 and are distributed in two rows up and down as shown in the figure. Adopting this layout method can make full use of the panel area of the programming socket 2, so that the programming socket 2 can be designed as small as possible, which is convenient for operation.

[0028] It can be understood that when programming a flash chip of one specification, the other specification ejector pins 5 may still cause obstruction. Based on this, in this embodiment, the 2*4 specification ejector pins 5 and the 2*8 specification ejector pins 5 are respectively arranged on two opposite panels of the programming socket 2. At the same time, as Figure 3As shown, a connecting plate 6 is also provided inside the programming socket 2. The connecting plate 6 can move relative to the programming socket 2 in the directions of the two panels respectively. Two types of specification ejector pins 5 are respectively arranged on both sides of the connecting plate 6, and corresponding through holes are arranged on the panels of the programming socket 2. When the connecting plate 6 moves towards one side panel of the programming socket 2, the 2*4 specification ejector pins 5 (or 2*8 specification ejector pins 5) can penetrate out of the corresponding through holes on the panel of the programming socket 2; when the connecting plate 6 moves towards the other side panel of the programming socket 2, the 2*8 specification ejector pins 5 (or 2*4 specification ejector pins 5) can penetrate out of the corresponding through holes on the other panel of the programming socket 2; when the connecting plate 6 is located at the central position inside the programming socket 2, both types of specification ejector pins 5 are retracted into the inside of the programming socket 2. Therefore, different states can be flexibly switched.

[0029] As a preferred embodiment, a control groove 7 is further provided on the side plate of the programming socket 2 in this embodiment. A control block 8 is slidably arranged in the control groove 7, and the control block 8 is connected to the connecting plate 4. Therefore, the control block 8 can be toggled as a switch to move the connecting plate 6 to a specific position, so that the programming socket 2 is in different states. Of course, in order to maintain the positions of the control block 8 and the connecting plate 6 after movement, a damping force can be further increased in the control groove 7, or a limiting groove 9 can be provided, so that the protruding part of the control block 8 can be stuck into the limiting groove 9 after the control block 8 moves into the limiting groove 9, thereby maintaining the state of the ejector pins 5 of different specifications protruding or retracting.

[0030] In addition, in order to make the connecting plate 6 move smoothly inside the programming socket 2, a guide rail slider assembly can be further provided between the inside of the programming socket 2 and the connecting plate 6 in this embodiment to prevent the ejector pins 5 from not being able to penetrate out due to non-parallel movement of the connecting plate 6. Among them, the connecting wire 4 directly extends into the programming socket 2 and is connected to the connecting plate 6, and the joint position can move along with the connecting plate 4.

[0031] In short, by using the portable software programming fixture provided in this embodiment, the programming of both SOP8 and SOP16 packages can be compatible at the same time. With the design of a three-position DIP switch, it can cope with various programming environments. In particular, it can directly program the flash chip on the PCB board without disassembling it, greatly saving the welding time and also reducing the problem of the PCB board pads falling off that may occur during the disassembly process. Therefore, using this fixture for programming can greatly reduce the time of hardware debugging and development and significantly improve the quality, and can also reduce losses to a certain extent.

[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0033] The above embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
