[0070] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0071] Chip reading and writing include two operations: reading chip program and burning chip program. To burn the chip program, the current program content in the chip can be overwritten.

[0072] Current chip reading and writing devices include a device body and a test head body. Usually, the device body and the test head are separated, and the device body and the test head are connected via a data cable or wireless methods such as Bluetooth. A burning button or display screen is provided on the device host. When the user reworks the chip, he needs to hold the test head with one hand to align and press the chip, and use the other hand to press the start button of the device body. He needs to consider both keeping the test head body in contact with the chip and observing the operation progress of the host interface of the device body. It is not very convenient to use and the experience is not good.

[0073] In view of this, the utility model provides a chip reading and writing device which is easy to use. The user holds the handheld part with one hand and controls the use posture of the test needle through the handheld part so that the test needle is aligned with the chip. At the same time, the hand holding the handheld part can also operate the burning button on the handheld part at the same time. The display panel displays relevant information. The user can observe the contact status of the test needle and the chip and the relevant information displayed on the display panel at the same time, which is more convenient to use and easy to operate.

[0074] The chip reading and writing device provided by the embodiment of the utility model is described below with reference to the accompanying drawings.

[0075] refer to Figure 1 and Figure 2 As shown, the utility model provides a chip reading and writing device, including: a handheld part 10, on which a display panel 11 and a burning button 71 are arranged. In the embodiment of the present application, the height of the handheld part 10 in the length direction is higher than the height in the direction perpendicular to the length direction, such as Figure 1 In the X-axis direction, in one embodiment of the present application, the handheld portion 10 is regarded as a rectangular parallelepiped, and the height of the handheld portion 10 is greater than its length or width.

[0076] Preferably, the test direction of the chip reading and writing device during the burning test is located in the length direction of the handheld part 10 .

[0077] In other embodiments of the present application, the test direction of the chip reading and writing device during the burning test can also be set at an angle to the length direction of the handheld part 10. For example, the probe is tilted at the bottom of the handheld part to facilitate observation when the probe is aligned with the chip contact.

[0078] In the embodiment of the present application, the hand-held portion 10 is configured as a rectangular parallelepiped to facilitate hand holding.

[0079] The handheld part also includes a test part 20, which is located at one end of the handheld part 10 in the length direction. In the embodiment of the present application, it is located at the test end, wherein a test pin 22 is provided on the test part 20, and the test pin 22 includes a power output interface; the test part 20 is used to read and write the chip, and the test pin 22 is aligned with the contact of the chip. The test pin 22 includes a data interface, which is used to perform subsequent reading and writing of the chip through the data interface. In one embodiment, the test pin also includes a power output interface, which is used to provide power to the chip through the power output interface. In another embodiment, the power output interface and the data interface are integrated together, which is suitable for different chips.

[0080] In the embodiment of the present application, the display panel 11, the burning button 71 and the testing unit 20 are arranged at intervals along the length direction of the chip reading and writing device.

[0081] The utility model provides a chip reading and writing device. The user holds the handheld part with one hand so that the test needle 22 is aligned with the chip. At the same time, the hand holding the handheld part 10 can also operate the handheld part 10 at the same time. The display panel 11 displays relevant information. The user can observe the contact between the test needle 22 and the chip while conveniently observing the relevant information displayed on the display panel 11. The user can start burning with one key, which is more convenient to use and easy to operate. The handheld part 10 is used to control the use posture of the test needle 22. By holding the handheld part 10, it is convenient to control the position of the test needle 22, the conduction and read / write status of the test needle 22, etc.

[0082] refer to Figure 1 and Figure 2 As shown, the display panel 11 is located at an end away from the test section 20 , and the burn button 71 is disposed between the display panel 11 and the test section 20 .

[0083] In an embodiment of the present application, the display panel 11 is far away from the test end (that is, the test unit 20 is at the bottom and the display panel 11 is at the top), and the burning process is closer to the human eye, which is convenient for observation; and the burning button 71 is located on the lower side of the display panel 11 and is arranged between the display panel 11 and the test unit 20. When burning, a person holds the middle position of the hand-held unit 10, and the fingers can more conveniently touch and press the burning button 71. In addition, the burning button 71 is arranged close to the test unit 20, which can reduce the deviation stroke of the test needle 22 caused by the force on one side of the hand-held unit when pressing, thereby avoiding burning failure.

[0084] When in use, the user usually holds the device with the thumb on the human-computer interface, facing the user, and four fingers on the back to form a grip, which is convenient for holding the chip reading and writing device, and also convenient for operating and viewing the display panel 11. At this time, the thumb is used to operate the operation button 18 and confirm the burning of the burning button 71.

[0085] In another embodiment of the present application, the display panel 11 is located at an end away from the testing unit 20 , and the burning button 71 is disposed on the side of the handheld unit 10 at an angle to the plane where the display panel 11 is located.

[0086] Through experiments, it was found that when the burning button 71 and the display panel 11 are both set on the front surface of the handheld part 10, after the test needle 22 fixed on the test part 20 is aimed at the contact of the chip to be burned, because the thumb does not press the burning button 71 tightly at the beginning, the palm of the hand is not subjected to force, and the gripping force on it is suspended. Then, in the process of the thumb pressing the burning button 71, the gripping force gradually increases, and there will be uncontrollable jitter, which may cause the test needle 22 to deviate from the chip contact, resulting in burning failure.

[0087] In a possible implementation, the plurality of finger contact positions include a thumb contact position, an index finger contact position, a middle finger contact position, a ring finger contact position, and a little finger contact position. The thumb contact position may also be located on the top surface of the handheld portion 10, and the remaining four finger contact positions are located on the side of the handheld portion 10.

[0088] In one possible implementation, reference Figure 1 and Fig. 9 As shown, the test button 70 includes a burning button 71, and the burning button 71 is arranged on the side of the hand-held part 10. The burning button 71 can be at a position on the side of the hand-held part 10 that contacts the remaining four fingers except the thumb. For example, the burning button 71 is at a position on the side of the hand-held part 10 that contacts the index finger, that is, the index finger contact position. Except for the palm, thumb, and index finger contact position of the user, the other three fingers can always be gripped before and after pressing the burning button 71, and there is an encircling gripping force. After the index finger presses the burning button 71, the shaking force is greatly reduced due to the existence of the gripping force, so that stable burning can be performed.

[0089] In an embodiment of the present application, the burning button 71 can also be set at the position where the top surface of the hand-held part 10 contacts the thumb, that is, the thumb contact position on the top surface of the hand-held part 10. Before and after pressing the burning button 71, the palm and the other four fingers form a gripping force, which can also reduce the shaking force and ensure stable burning.

[0090] In the embodiment of the present application, the burn button 71 is arranged on the side of the handheld portion 10, which is not necessarily the side perpendicular to the front surface where the display panel 11 is located, and can also be arranged at a certain angle, so that it is easier to touch when the finger is bent around the handheld portion 10, such as Fig. 9 shown.

[0091] In one embodiment of the present application, projections of the burning button 71 and the midpoint of the testing portion 20 in the length direction of the handheld portion 10 overlap.

[0092] In the embodiment of the present application, the projections of the midpoints of the burn button 71 and the test unit 20 in the length direction of the handheld unit 10 overlap. When pressing the burn button 71, the force applied can be as close to the center of the test unit 20 as possible to further reduce jitter.

[0093] In the embodiment of the present application, the burning button 71 can be a mechanical button or a touch button.

[0094] In one embodiment of the present application, the burning button 71 is arranged on the plane where the display panel 11 is located, the test unit 20 is arranged on a plane perpendicular to the plane where the display panel 11 is located, and the display panel 11, the burning button 71 and the test unit 20 are arranged in sequence along the length direction of the handheld unit 10.

[0095] like Figure 1 As shown, the burning button 71 and the display panel 11 are both arranged on the front surface, and the display panel 11, the burning button 71 and the test part 20 are arranged in sequence from top to bottom along the length direction of the hand-held part 10, which is convenient for hand-held operation and observation of the burning process. The hand-held position will not block the screen, and is close to the test part 20, so that the center of gravity of the test is moved downward, the contact is more stable, and the jitter of the test process is reduced. The display panel 11 and the burning button 71 are arranged on the same surface and close to it. The burning process is facing the operator and closer to the operator's eyes, which is convenient for observation.

[0096] In the embodiment of the present application, the height in any direction perpendicular to the length direction is less than or equal to 10 cm; the height of the burning button 71 from the test pin 22 is greater than or equal to 3 cm; the distance from the base of the thumb to the farthest joint of the finger of an average person does not exceed 10 cm. Therefore, the length and width of the hand-held portion 10 should not be too large, and should be ensured to be within this range for the convenience of human hand holding and pressing the burning button 71. In addition, the height between the burning button 71 and the test pin 22 should not be too small. When the human hand grasps, the thumb can contact the burning button 71 on the front surface, and should not deviate too much. It is best for the thumb to contact in parallel. At this time, the distance between the thumb and the lowest little finger is about 3 cm. Therefore, the height of the burning button 71 from the test pin 22 is greater than or equal to 3 cm to avoid the little finger interfering with the burning operation.

[0097] Preferably, the height of the hand-held part 10 in the length direction is greater than or equal to twice the height in other directions perpendicular thereto; the hand-held part 10 forms a long strip structure, which is easy for human body to grasp, and leaves enough space for setting the display panel 11 and the burning button 71.

[0098] In an embodiment of the present application, the handheld unit 10 equipped with the test unit 20 can be connected to the test host by wire or wirelessly. When performing the burning operation, you can mainly observe the display panel 11 of the handheld unit and operate the burning buttons without having to devote too much attention to the test host.

[0099] In a preferred embodiment of the present application, the burning device also includes a test host, which is arranged in the handheld part 10 and integrated into an integrated structure. The handheld part 10 and the test part 20 are detachably connected; when the handheld part 10 and the test part 20 are in a connected state, the test part 20 and the test host are electrically connected.

[0100] refer to Figure 1 and Figure 2As shown, the test part 20 is provided with an electrically connected second conductive part 21 and a test pin 22. When the test part 20 and the handheld part 10 are connected to each other, the second conductive part 21 abuts against the first conductive part 12, thereby achieving conduction between the first conductive part 12 and the test pin 22 and realizing communication connection. Of course, the second conductive part 21 and the first conductive part 12 can also be conducted through an adapter. There is no need to use a connecting wire to connect the test part 20 and the test host, which reduces the interference of the wire length on the signal. In addition, the test host and the handheld part are integrated together for easy operation, and the entire burning device can be set to be more simplified and compact.

[0101] In a possible implementation, the test needle 22 may be located at the end of the test portion 20 to facilitate the test needle 22 to contact the contact point of the chip to be programmed.

[0102] In one possible implementation, there are multiple test needles 22, and the shapes of the test needles 22 include but are not limited to cylindrical, polygonal columnar, etc. They can be selected according to the contacts of the chip to be burned, so as to be suitable for different chips to be burned, thereby improving the versatility of the chip reading and writing device. The arrangement shape of the multiple test needles 22 is not specifically limited here.

[0103] In a possible implementation, a mounting cavity 13 is provided in one of the handheld portion 10 and the test portion 20, and the other of the handheld portion 10 and the test portion 20 has a connecting portion 24 pluggably connected to the mounting cavity 13. By plugging and unplugging the connecting portion 24 into the mounting cavity 13, the stability of the connection between the handheld portion 10 and the test portion 20 can be improved.

[0104] When the handheld part 10 and the testing part 20 are in a connected state, the testing part 20 is electrically connected to a testing host disposed in the handheld part 10 .

[0105] In one embodiment of the present application, reference Figure 1 and Figure 2 As shown, in the first embodiment, a mounting cavity 13 is provided in the handheld part 10, and the test part 20 has a connection part 24 pluggably connected to the mounting cavity 13. By directly plugging and unplugging the connection part 24 in the mounting cavity 13, the handheld part 10 and the test part 20 are connected as a whole, achieving a stable connection effect between the handheld part 10 and the test part 20, and making it unnecessary to use wires for signal transmission between the test host in the handheld part 10 and the test part 20, which can effectively solve the signal interference problem caused by the line length.

[0106] Reference for the plugging and unplugging direction of the test unit 20 Figure 1 The arrow X indicates the direction.

[0107] In a possible implementation, the handheld part 10 may be a female plug and the testing part 20 may be a male plug. Of course, the handheld part 10 may also be a male plug and the testing part 20 may be a female plug.

[0108] In a possible implementation, the display panel 11 may be a touch screen, and interactive operations on the chip reading and writing device are implemented by touching the touch screen.

[0109] In a possible implementation, the handheld portion 10 is further provided with an operating button 18 , and the operating button 18 and the display panel 11 are located on the same surface of the handheld portion 10 .

[0110] In one possible implementation, the operating button 18 may be located on the upper side, upper side, left side or right side of the display panel 11. The operating button 18 includes but is not limited to at least one of a button and a knob. The operating button 18 is used to interactively input the display panel 11. The operating button 18 also includes a power button, which is used to start and shut down the burning device.

[0111] In a possible implementation, the first conductive part 12 may be a communication contact, or a contact pin, such as a pogo pin, so that the first conductive part 12 is connected to the second conductive part 21 of the test part 20 to transmit signals.

[0112] In one possible implementation, a separation portion 23 is provided on the hand-held portion 10 or the test portion 20, and the separation portion 23 is used to lock or separate the hand-held portion 10 and the test portion 20; the form of the separation portion 23 is not limited, and it can be electromagnetic or mechanical, as long as it can achieve rapid locking or separation of the hand-held portion 10 and the test portion 20.

[0113] In one possible implementation, a first snap-fitting portion 14 is provided on the side wall of the mounting cavity 13, and a separation portion 23 (the separation portion 23 can be regarded as a second snap-fitting portion) is provided on the outer wall of the testing portion 20, and the first snap-fitting portion 14 and the separation portion 23 are snap-fitted and connected to each other; one of the first snap-fitting portion 14 and the separation portion 23 is an elastic snap buckle, and the other is a slot.

[0114] There may be two separation parts 23, and the two separation parts 23 are respectively located on two opposite outer walls of the testing part 20. The position of the first engaging part 14 corresponds to the position of the separation part 23.

[0115] In this embodiment, the first locking portion 14 is a card slot, and the separation portion 23 is an elastic card buckle. When the elastic card buckle undergoes elastic deformation, it is inserted into the card slot, and after being inserted into the card slot, the deformation is restored, so that the connecting portion 24 is stably clamped in the installation cavity 13, ensuring a stable connection effect between the hand-held portion 10 and the test portion 20.

[0116] Of course, in other embodiments, the first engaging portion 14 may be an elastic buckle, and the separating portion 23 may be a slot. The stability of the connection between the hand-held portion 10 and the testing portion 20 may also be improved by the mutual engaging connection between the first engaging portion 14 and the separating portion 23 .

[0117] In an embodiment of the present application that is not shown in the figure, a first magnetic part is provided in the installation cavity 13, and a second magnetic part is provided in the connecting portion 24. The second magnetic part corresponds to the position of the first magnetic part, and the second magnetic part and the first magnetic part are magnetically attracted to each other. With such a structure, after the test part 20 is connected to the installation cavity 13, the second magnetic part and the first magnetic part are magnetically attracted to each other. Under the action of magnetic attraction, the test part 20 and the installation cavity 13 are prevented from being separated from each other, which can improve the stability of the connection between the handheld part 10 and the test part 20. After the handheld part 10 and the test part 20 are connected, the second conductive part 21 contacts the first conductive part 12 correspondingly, and conductive communication is achieved.

[0118] In a possible implementation, the first magnetic member and the second magnetic member are both magnets.

[0119] In other possible implementations, the first magnetic member may be a magnet, and the second magnetic member may be an iron sheet or an alloy sheet containing metallic iron. Alternatively, the second magnetic member may be a magnet, and the first magnetic member may be an iron sheet or an alloy sheet containing metallic iron.

[0120] In one possible implementation, reference Figure 1 and Figure 2 As shown, an elastic member 30 is disposed in the installation cavity 13, and two ends of the elastic member 30 are respectively abutted between the connecting portion 24 and the inner wall of the installation cavity 13. The elastic member 30 is provided to facilitate the connection portion 24 to be removed from the installation cavity 13, thereby improving the convenience of disassembly.

[0121] In one possible implementation, the elastic member 30 may be a compression spring, and the force direction of the elastic member 30 is along the removal direction of the test part 20 . To prevent the elastic member 30 from falling out, one end of the elastic member 30 is fixed to the inner wall surface of the installation cavity 13 .

[0122] After the test part 20 and the hand-held part 10 are connected to each other, the connecting part 24 squeezes the elastic member 30, so that the elastic member 30 is compressed to store force. Since the side wall of the installation cavity 13 is provided with a first clamping part 14, and the outer wall of the connecting part 24 is provided with a separation part 23, the test part 20 and the hand-held part 10 are clamped together under the mutual clamping action of the first clamping part 14 and the separation part 23, which can prevent the test part 20 and the hand-held part 10 from being separated from each other, and the elastic member 30 maintains a compressed state. At this time, when the first conductive part 12 is a spring needle, the first conductive part 12 and the elastic member 30 are both squeezed to generate a double thrust.

[0123] When the test part 20 needs to be disassembled, the elastic buckles in the first clamping part 14 and the separating part 23 can be manually pressed to separate the first clamping part 14 and the separating part 23 from each other. Under the elastic force of the elastic member 30, the connecting part 24 can be easily taken out of the mounting cavity 13 without any effort, and the test part 20 and the hand-held part 10 can be separated from each other.

[0124] In an embodiment of the present application not shown in the figure, a third positioning part is further provided in the installation cavity 13, and a fourth positioning part is provided in the connecting part 24, and the third positioning part and the fourth positioning part cooperate with each other. The third positioning part can be a convex column and the fourth positioning part can be a groove; or the third positioning part can be a groove and the fourth positioning part can be a convex column. By correspondingly extending the convex column into the groove, the accuracy of the corresponding contact between the second conductive part 21 and the first conductive part 12 is improved, and the problem of misalignment and affecting the communication stability is prevented.

[0125] In one possible implementation, reference Figure 1 and Figure 2 As shown, the inner and outer walls of the installation cavity 13 are provided with assembly grooves 131, and there is a gap between the assembly grooves 131 and the connecting portion 24. The purpose is to reduce the contact area between the connecting portion 24 and the inner wall of the installation cavity 13, thereby reducing the friction force and making the installation and removal of the test portion 20 smoother.

[0126] This is because the first conductive part 12 must be aligned with the second conductive part 21 to ensure contact, so when the test part 20 is installed on the handheld part 10, the gap between the connecting part 24 and the inner wall of the installation cavity 13 needs to be smaller, which will cause the friction force of plugging and unplugging the test part 20 to be larger, making it more difficult to remove the test part 20. In this embodiment, by providing the assembly groove 131, the contact area between the connecting part 24 and the inner wall of the installation cavity 13 can be reduced, making it easier to plug and unplug the test part 20.

[0127] In one possible implementation, reference Figure 2 As shown, the inner wall of the mounting cavity 13 is provided with a first guide portion 15, and the outer wall of the connecting portion 24 is provided with a second guide portion 25, and the second guide portion 25 corresponds to the position of the first guide portion 15; one of the first guide portion 15 and the second guide portion 25 is a guide groove, and the other of the first guide portion 15 and the second guide portion 25 is a guide protrusion, and the guide protrusion is slidably matched with the guide groove.

[0128] In a possible implementation, the first guide portion 15 may be a guide groove, and the second guide portion 25 may be a guide protrusion; or the second guide portion 25 may be a guide groove, and the first guide portion 15 may be a guide protrusion. The guide protrusion and the guide groove slide together to guide the test portion 20 when it is installed in the handheld portion 10, which helps prevent the test portion 20 from being deflected or stuck. In addition, if the second guide portion 25 is not aligned with the first guide portion 15 during installation, the connecting portion 24 will not be installed in the installation cavity 13, which can prevent the test portion 20 from being installed upside down, thus playing a fool-proof role.

[0129] The guide groove extends along the plugging and unplugging direction of the test part 20. The cross section of the guide groove can be rectangular, semicircular, etc. The cross section shape of the guide protrusion is consistent with the cross section shape of the guide groove, which is beneficial to improve the guiding effect.

[0130] In one possible implementation, reference Figure 3 and Figure 4 As shown, a chip reading and writing device provided by an embodiment of the utility model also includes a first protective cover 40, and a first protective cavity is opened in the first protective cover 40; when the test part 20 and the hand-held part 10 are connected to each other, the test part 20 is located in the first protective cavity, and the first protective cavity is connected to the hand-held part 10 or the test part 20.

[0131] The first protective cover 40 is mainly used to protect the test needle 22 of the test part 20. When the test part 20 and the hand-held part 10 are connected to each other, the test part 20 can be covered in the first protective cavity by connecting the opening end of the first protective cavity to the hand-held part 10, thereby achieving a better effect of protecting the test part 20.

[0132] In a possible implementation, the first protective cover 40 may be connected to the handheld part 10 or the test part 20 by snapping. For example, a mounting buckle 19 is provided on the surface of the handheld part 10, and a concave point is provided on the inner wall of the first protective cavity. By snapping the mounting buckle 19 into the concave point, the clamping effect of the first protective cover 40 after being fixed can be improved, and the problem of the first protective cover 40 being loosened can be prevented.

[0133] In a possible implementation, an outer convex groove 41 is provided at the open end of the first protective cavity, and the outer convex groove 41 is used to accommodate the elastic buckle in the first engaging portion 14 and the separating portion 23 .

[0134] By using the protective cover provided in the present application, the test needle 22 is protected when the burning device stops burning and temporarily moves.

[0135] In one possible implementation, reference Figure 5As shown, a chip reading and writing device provided by an embodiment of the utility model further includes a second protective cover 50, and a receiving cavity 51 is formed between the second protective cover 50 and the first protective cover 40; when the test part 20 and the handheld part 10 are separated from each other, the test part 20 is arranged in the receiving cavity 51. Through the cooperation between the first protective cover 40 and the second protective cover 50, the test part 20 is protected, and the first protective cover 40 achieves a dual-purpose effect.

[0136] In one possible implementation, reference Figure 2 and Figure 5 As shown, the inner wall of the second protective cover 50 is further provided with a third guide portion 53, the position of the third guide portion 53 corresponds to the position of the second guide portion 25 provided on the outer wall of the connecting portion 24, and the third guide portion 53 and the second guide portion 25 are slidably matched; one of the third guide portion 53 and the second guide portion 25 is a sliding groove, and the other is a sliding protrusion. The third guide portion 53 and the second guide portion 25 are slidably matched, which plays a role in preventing the second protective cover 50 from being deflected or installed upside down, and has a fool-proof effect.

[0137] In a possible implementation, one of the third guide portion 53 and the second guide portion 25 is a slide groove, and the other is a sliding protrusion. For example, the third guide portion 53 may be a slide groove, and the second guide portion 25 may be a sliding protrusion; or the third guide portion 53 may be a sliding protrusion, and the second guide portion 25 may be a slide groove. The extension direction of the slide groove is consistent with the installation direction of the second protective cover 50, and the sliding protrusion slides along the slide groove, which plays a guiding role in the installation and removal of the second protective cover 50.

[0138] In one possible implementation, reference Figure 2 and Figure 5 As shown, the side wall of the second protective cover 50 is provided with a fitting groove 52 and a fitting buckle 54. When the test part 20 and the hand-held part 10 are separated from each other, the separation part 23 provided on the outer wall of the test part 20 extends to the outside of the first protective cover 40 through the fitting groove 52, and the separation part 23 and the fitting groove 52 are engaged with each other, and the fitting buckle 54 is engaged with the inner wall of the first protective cover 40. Thus, the stable fitting connection effect of the first protective cover 40 and the second protective cover 50 is ensured, and the first protective cover 40 and the second protective cover 50 are prevented from falling off from the test part 20.

[0139] In this example, the separation portion 23 is an elastic buckle, and the fitting groove 52 is a slot that penetrates the side wall of the second protective sleeve 50. The inner wall of the first protective sleeve 40 is provided with a recessed portion that matches the shape of the fitting buckle 54, and the fitting buckle 54 is embedded in the recessed portion, which can improve the stability of the connection between the first protective sleeve 40 and the second protective sleeve 50.

[0140] When the test part 20 and the hand-held part 10 are separated from each other, the test part 20 is placed in the second protective cover 50, and the separation parts 23 on both sides of the test part 20 pass through the fitting grooves 52 and are fixed by snapping, so that the second protective cover 50 is fixed relative to the test part 20, and then the second protective cover 50 is fitted with the first protective cover 40. Under the action of the fitting buckle 54, a stable fitting connection effect between the first protective cover 40 and the second protective cover 50 is achieved to protect the test part 20. At this time, the separation parts 23 on both sides of the test part 20 are accommodated in the outer convex grooves 41 of the first protective cover 40, forming all-round protection for the test part 20, which can prevent dust from falling into the test part 20 and facilitate the storage of the test part 20.

[0141] In one possible implementation, the fitting groove and the first engaging portion of the device body (handheld part) have the same structure, and the fitting buckle and the mounting buckle provided on the device body (handheld part) have the same structure, which makes it easier to match the same first protective cover structure of the box.

[0142] In a possible implementation, in order to facilitate fixing the chip reading and writing device in this example at the tooling station, refer to Figure 6 and Figure 7 As shown, a chip reading and writing device provided by an embodiment of the utility model also includes a card clamp 60, which includes a back plate 61 and a first clamping portion 62 and a second clamping portion 63 respectively connected to both ends of the back plate 61, a clamping cavity 64 is formed between the first clamping portion 62 and the second clamping portion 63, and the hand-held portion 10 is located in the clamping cavity 64. The first clamping portion 62 and the second clamping portion 63 are respectively clamped on the opposite side edges of the hand-held portion 10, so as to facilitate quick removal and insertion of the hand-held portion 10 without screwing, and is easy to use.

[0143] refer to Figure 6 and Figure 7 As shown, the first clamping portion 62, the second clamping portion 63 and the back plate 61 can be an integral structure connected in one piece. The first clamping portion 62 and the second clamping portion 63 can be structures formed at both ends of the back plate 61 and bent toward the direction of the handheld portion 10 respectively. The structure is simple and easy to use.

[0144] In a possible implementation, the handheld portion 10 is provided with a first positioning portion 16, and the back plate 61 is provided with a second positioning portion 65; one of the first positioning portion 16 and the second positioning portion 65 is a positioning groove, and the other is a positioning column, and the positioning column extends into the positioning groove.

[0145] In one possible implementation, the first positioning portion 16 can be a positioning groove, and the second positioning portion 65 can be a positioning column; or the first positioning portion 16 can be a positioning column, and the second positioning portion 65 can be a positioning groove; by extending the positioning column into the positioning groove, the positioning effect of the hand-held portion 10 in the clip 60 is achieved.

[0146] A screw hole 611 is provided in the back plate 61. During installation, the clamp 60 is first fixed to the tooling equipment by passing the screws through the screw holes 611, and then the hand-held part 10 is clamped in the clamping cavity 64. The first positioning part 16 and the second positioning part 65 cooperate with each other to achieve the clamping and fixing effect of the hand-held part 10.

[0147] In a possible implementation, the test unit 20 includes a program burner. When the test unit 20 and the handheld unit 10 are connected to each other, the test host in the handheld unit 10 obtains the burning program carried by the program burner.

[0148] It is easy to understand that the program burner is also called a program editor, which usually includes a main control board, a storage device for storing the burning program, and an interface for writing the burning program, etc. When the test unit 20 and the handheld unit 10 are connected to each other, the second conductive part 21 is electrically connected to the first conductive part 12, so that the test unit 20 is electrically connected to the test host in the handheld unit 10, and the test host can obtain the burning program carried by the program burner.

[0149] With such a structure, the program burners of each test unit 20 can store different burning programs respectively. By replacing the test unit 20 connected to the handheld unit 10, different burning programs can be selected. There is no need to store a large number of burning programs in the test host in the handheld unit 10 for selection and use, which makes the entire burning device compact and versatile.

[0150] When a new chip or a new program needs to be burned, only the test unit 20 storing the updated burning program needs to be replaced, and there is no need to upgrade the test host in the handheld unit 10, which is more convenient to use.

[0154] In the embodiment of the present application, the test host is the main control device, and a printed circuit board is installed inside the test host, so that the programming pen can realize functions such as human-machine interface display, software function control, test unit control, and network upgrade control.

[0155] Since the handheld part 10 integrates the test host, the volume of the entire burning device is relatively small, and the test part 20 is directly installed on the inner side of the handheld part 10. The handheld part 10 has a built-in battery, so no wires are required, and one-handed operation, such as function selection, parameter setting, chip writing and inspection, can be performed with one hand. In addition, the test host in the handheld part 10 and the test part 20 do not need to be connected by wires, and are connected with POGOPIN, which is conducive to reducing signal interference.

[0156] There are heat dissipation holes 113 on both sides of the handheld part 10, and convection wind can make the handheld part 10 dissipate heat faster.

[0157] In another embodiment of the present application, a mounting cavity 13 is provided in the test part 20, and the handheld part 10 has a connection part 24 pluggable and connected to the mounting cavity 13. By directly plugging and connecting the connection part 24 in the mounting cavity 13, the handheld part 10 and the test part 20 are connected as a whole, a stable connection effect between the handheld part 10 and the test part 20 is achieved, and there is no need to use wires for signal transmission between the handheld part 10 and the test part 20, which can effectively solve the signal interference problem caused by the line length.
