Fig.14 This is a schematic diagram of the overall structure of the conversion device provided by another embodiment of the utility model after accommodating the chip.

[0035] The conversion device 100 includes a first chip seat 1, a second chip seat 2 and an interface 3. The first chip seat 1 includes a first contact group, which is used to fix the chip 300 and make electrical contact with the electrical contacts on the first side of the chip 300 when the information reading and writing device reads and writes information to the chip 300; the second chip seat 2 includes a second contact group, which is used to make electrical contact with the electrical contacts on the second side of the chip 300 when the information reading and writing device reads and writes information to the chip 300; and the interface 3 is electrically connected to the first contact group and the second contact group, and is used to make electrical connection with the information reading and writing device when the information reading and writing device reads and writes information to the chip 300.

[0036] The first contact group includes at least one first contact 1A, and the second contact group includes at least one second contact 2A.

[0037] In chip programming, the programming points of some chips are concentrated on only one side of the chip, while the programming points of some chips are distributed on multiple sides of the chip due to layout design, functional design and other reasons. Figure 3 and Figure 4 As shown, the chip 300 is in the shape of a conventional circuit board, and its burning points are distributed on two surfaces of the chip 300. The burning points 300B in one surface are used to electrically contact the first contacts 1A in the first contact group in the conversion device 100, and the burning points 300A in the other surface are used to electrically contact the second contacts 2A in the second contact group in the conversion device 100.

[0038] Therefore, the conversion device 100 provided by the present invention includes at least two contact groups (first contact group, second contact group), which can make electrical contact with at least two surfaces (first surface, second surface) of the chip 300. At the same time, the conversion device 100 can be electrically connected to the information reading and writing device through the interface 3, so that the information reading and writing device can read and write information on the chip 300 with multiple electrical contact surfaces. At the same time, the conversion device 100 mainly makes electrical contact with the chip 300 through the first contact group in the first chip seat 1, the second contact group in the second chip seat 2 and the chip 300, and the interface 3 is electrically connected to the information reading and writing device, so that the information reading and writing device can read and write information on the chip 300 located on the conversion device 100, and the structure is simple and the operation is simple.

[0039] Obviously, the conversion device 100 provided by the utility model can burn chips with burning points distributed on multiple surfaces, and naturally can also burn chips with burning points concentrated on only one surface. For chips with burning points concentrated on only one surface, the first contact group or the second contact group can be removed.

[0040] Among them, Figure 1-Figure 4 , Figure 13-14As shown, every two adjacent second contacts 2A are used to make electrical contact with the same electrical contact 300A on the second side of the chip 300 , thereby enhancing the stability of the electrical contact between the second contacts 2A and the electrical contacts 300A on the second side of the chip 300 .

[0041] Generally speaking, as long as the first chip seat 1 and the second chip seat 2 are closed so that the first contact group in the first chip seat 1 and the second contact group in the second chip seat 2 are respectively in contact with the electrical contacts on the chip 300, and the interface 3 is electrically connected to the information reading and writing device, the information reading and writing device can read and write information on the chip 300 located on the conversion device 100.

[0042] Furthermore, if Figure 1-Figure 4 , Figure 13-14 As shown, the first chip holder 1 further includes a receiving groove 1C, which is used to receive the chip 300 so as to fix the chip 300 , and a first contact group is disposed in the receiving groove 1C.

[0043] The shape of the receiving groove 1C matches the outer contour of the chip 300 , so that the chip 300 can be just placed in the receiving groove 1C, so that the receiving groove 1C can fix the chip 300 .

[0044] In some embodiments, since the receiving slot 1C itself is not conductive, the first contact group is disposed in the receiving slot 1C while being electrically connected to the interface 3. When the chip 300 is placed in the receiving slot 1C, that is, the receiving slot 1C fixes the chip 300, the portion of the first contact group in the receiving slot 1C is electrically connected to the contacts 300B on the first surface of the chip 300.

[0045] The method of fixing the chip 300 by the receiving groove 1C has a simple structure, low implementation difficulty and a certain reliability.

[0046] Among them, due to Figure 3 There is only one contact 300B for electrical contact with the first contact group shown in the figure, and it is distributed at the corners of the chip 300. When the chip 300 is placed in the receiving slot 1C, if there is only one contact in the receiving slot 1C corresponding to the contact 300B in the chip 300, it may cause the chip 300 to be supported in the receiving slot 1C. The support force is unstable or unbalanced. Therefore, the receiving slot 1C is also provided with a support contact 1B with the same shape as the contact 1A, which is used to support the chip 300 in the receiving slot 1C so that the chip 300 is balanced in the receiving slot 1C. When the information reading and writing device reads and writes information to the chip 300, the contact 1A is in a conductive state, and the support contact 1B is in a non-conductive state, which only plays a supporting role.

[0047] Furthermore, in some embodiments, a positioning column 1C1 is further provided in the receiving groove 1C, which is used to position the chip 300, thereby fixing the chip 300. Specifically, in the embodiment provided by the utility model, chips 300 of different shapes are read and written by different conversion devices 100, and in different conversion devices 100, the positioning columns 1C1 in the receiving groove 1C of the first chip seat 1 are different. That is, in the embodiment provided by the utility model, different conversion devices 100 have positioning columns 1C1 of different positions, quantities and shapes according to the different external structures of the chips 300 to which they are applicable, so as to position and fix the chips 300 to which they are applicable.

[0048] For example, Figure 3-Figure 4 The chip 300 shown has a limiting hole 300C due to various design reasons. Therefore, when the information reading and writing equipment reads and writes information on it through the conversion device 100, that is, when the chip 300 is accommodated in the receiving groove 1C of the conversion device 100, a corresponding positioning column 1C1 is required to position it, so that the chip 300 can be better fixed in the receiving groove 1C.

[0049] By positioning the chip 300 in the receiving groove 1C through the positioning column 1C1, the chip 300 can not only be limited so that it can be better aligned with the first contact 1A in the first contact group and the second contact 2A in the second contact group in the conversion device 100, but also the chip 300 can be better fixed due to the abutment effect of the positioning column 1C1.

[0050] In some embodiments, the first chip seat 1 and the second chip seat 2 are two independent objects with no physical connection and no corresponding connection structure. When the information reading and writing device reads and writes information on the chip 300, the operator manually closes the first chip seat 1 and the second chip seat 2 so that the first contact group in the first chip seat 1 and the second contact group in the second chip seat 2 are respectively in contact with the electrical contacts on the chip 300. At the same time, since the information reading and writing process of the chip 300 takes a certain amount of time, the operator is required to manually keep the first chip seat 1 and the second chip seat 2 closed during this process to realize the information reading and writing of the chip 300.

[0051] In some other embodiments, the first chip holder 1 and the second chip holder 2 are connected to each other in a certain manner. For example, the first chip holder 1 and the second chip holder 2 are connected by a hinge. Figure 5-7 As shown, Figure 5 This is a schematic side structural diagram of a conversion device 100 provided in an embodiment of the utility model in a first state. Figure 6 This is a schematic diagram of the side structure of the conversion device 100 provided by an embodiment of the utility model when it is in the second state. Figure 7A schematic diagram of the side structure of a conversion device 100 provided in an embodiment of the utility model when it is in the third state, wherein the first state refers to the state when the first chip holder 1 and the second chip holder 2 are not closed, the second state refers to the state before the first chip holder 1 and the second chip holder 2 are ready to be closed, and the third state refers to the state after the first chip holder 1 and the second chip holder 2 are closed. Since the first chip seat 1 and the second chip seat 2 are connected by a hinge, the first chip seat 1 and the second chip seat 2 can rotate relative to each other. When the information reading and writing device needs to read and write information on the chip 300, it is only necessary to fix the first chip seat 1 or the second chip seat 2, and then rotate the second chip seat 2 or the first chip seat 1 relative to the fixed first chip seat 1 or the second chip seat 2 until the first chip seat 1 and the second chip seat 2 are closed and the first contact group on the first chip seat 1 is in electrical contact with the contact 300B on the first side of the chip 300, and the second contact group on the second chip seat 2 is in electrical contact with the contact 300A on the second side of the chip 300. It has a simple structure and is easy to operate, which is conducive to improving the efficiency of the information reading and writing device in reading and writing information on the chip 300 through the conversion device 100. Figure 5-7 In the illustrated embodiment, the first chip holder 1 accommodating the chip 300 is generally fixed, and the second chip holder 2 is rotated relative to the first chip holder 1 until the first chip holder 1 and the second chip holder 2 are closed.

[0052] In some embodiments, the first chip holder 1 and the second chip holder 2 are two objects that are independent of each other but have certain corresponding connection structures. For example, when the conversion device 100 is not in use, the first chip holder 1 and the second chip holder 2 are two independent objects; when the information reading and writing device reads and writes information to the chip 300, the first chip holder 1 and the second chip holder 2 are connected by a snap-fitting manner, so that the first contact group on the first chip holder 1 is in electrical contact with the contacts on the first surface of the chip 300, and the second contact group on the second chip holder 2 is in electrical contact with the contacts on the second surface of the chip 300. That is, the first chip holder 1 and the second chip holder 2 respectively include a snap-fitting structure and a snap-fitting structure that can correspond to each other, so that the first chip holder 1 and the second chip holder 2 can be closed through the snap-fitting structure and the snap-fitting structure so that the first contact group on the first chip holder 1 is in electrical contact with the contacts on the first surface of the chip 300, and the second contact group on the second chip holder 2 is in electrical contact with the contacts on the second surface of the chip 300. Therefore, when the information reading and writing device reads and writes information on the chip 300, the first chip seat 1 and the second chip seat 2 can be kept closed by the snap-fitting method without the operator having to manually maintain the state between the first chip seat 1 and the second chip seat 2 all the time, thereby facilitating the operator's operation and improving the operational efficiency of information reading and writing.

[0053] Furthermore, in some embodiments, Figure 5-10As shown, Figure 8 This is a partial structural exploded view of the first chip holder of the conversion device provided by one embodiment of the utility model. Fig. 9 This is a schematic side structural diagram of a conversion device provided by an embodiment of the utility model in a fourth state, Fig.10 This is an exploded view of the partial structure of the second chip holder of the conversion device provided in one embodiment of the utility model, wherein the fourth state refers to the state when the first chip holder 1 and the second chip holder 2 are ready to disengage. One end of the first chip holder 1 is connected to one end of the second chip holder 2 by a hinged manner, and when the information reading and writing device reads and writes information to the chip 300, the other end of the first chip holder 1 is connected to the other end of the second chip holder 2 by a snap-fit ​​manner. Therefore, the operation method of closing the first chip holder 1 and the second chip holder 2 is simple, and the structure of continuously closing the first chip holder 1 and the second chip holder 2 is simple, which is conducive to improving the efficiency of the information reading and writing device in reading and writing information to the chip 300 through the conversion device 100.

[0054] Specifically, regarding the engagement method between the first chip holder 1 and the second chip holder 2, in some embodiments, as shown in FIG. Figure 8As shown, the first chip holder 1 includes a first housing 11 and a first engaging member 12, the first engaging member 12 includes a first engaging member 121, a first rotating shaft 122 and a first elastic member 123, the first rotating shaft 122 is connected to the first engaging member 121 and the first housing 11 and enables at least one of the first engaging member 121 and the first housing 11 to rotate around the first rotating shaft 122, one end of the first elastic member 123 is connected to the first engaging member 121, and the other end is connected to the first housing 11. The first engaging member 12 is used to engage the second chip holder 2, so that the first chip holder 1 and the second chip holder 2 are connected together by engaging. More specifically, the first engaging member 121 is used to engage the second chip holder 2; the first rotating shaft 122 enables the first engaging member 121 to rotate relative to the first shell 11, so that when the first engaging member 121 is about to engage the second chip holder 2 and when the first engaging member 121 is released from engaging the second chip holder 2, the first engaging member 121 has a certain rotational movement space to reduce the wear of the first engaging member 121 and the second chip holder 2 caused by the friction between the first engaging member 121 and the second chip holder 2; the first elastic member 123 is used to reset the first engaging member 121 to a normal position with the first shell 11, wherein the normal position refers to the first chip holder 1 The relative position of the first engaging member 121 and the first shell 11 when the second chip holder 2 is not yet engaged with each other, the normal position is also the relative position of the first engaging member 121 and the first shell 11 after the first chip holder 1 and the second chip holder 2 are engaged with each other, and the normal position is also the position when the first engaging member 121 and the first shell 11 are in a stable state with respect to each other, that is, the relative rotation between the first engaging member 121 and the first shell 11 occurs in the process from when the first chip holder 1 and the second chip holder 2 are ready to engage to when the engagement is completed, or in the process from when the first chip holder 1 and the second chip holder 2 are ready to disengage from the engagement state to when the disengagement is completed.

[0055] Therefore, the first chip seat 1 and the second chip seat 2 are clamped together by the first clamping component 12, and the first clamping component 12 also includes a first clamping component 121, a first rotating shaft 122 and a first elastic component 123, which can reduce the wear of the first clamping component 121 and the second chip seat 2 during the process of clamping or releasing the first chip seat 1 and the second chip seat 2. At the same time, the first elastic component 123 can also reset to the normal position between the first clamping component 121 and the first shell 11.

[0056] Furthermore, in some embodiments, the first elastic member 123 is a spring, and the first shell 11 includes a first contact surface and a second contact surface, and the first contact surface is used to face the second chip seat 2 and contact the second chip seat 2 when the information reading and writing device reads and writes information on the chip 300; one end of the spring is connected to the first clamping member 121, and the other end of the spring is connected to the second contact surface, wherein the first contact surface and the second contact surface are facing in opposite directions.

[0057] Therefore, when the first chip holder 1 and the second chip holder 2 are ready to be engaged, since the first engaging member 121 itself has a guiding slope, the second chip holder 2 can be more smoothly engaged to the engaged position (such as Figure 6-7 As shown, during this process, due to the existence of the first rotating shaft 122, that is, due to the relative rotation of the first engaging member 121 and the first housing 11, the first engaging member 121 will be subjected to the force from the second chip holder 2 and rotate relative to the first housing 11, so that the second chip holder 2 can be better engaged to the position when the engagement is completed. Figure 8 The first elastic member 123 shown is a spring, so that when the second chip holder 2 is inserted into the position where the engagement is completed (such as Figure 7 After that, the relative position between the first engaging member 121 and the first housing 11 can be restored to a normal position, at which time the first engaging member 121 can clamp the second chip holder 2, making it difficult to separate from the first chip holder 1.

[0058] When the first chip holder 1 and the second chip holder 2 are ready to be released from engagement, the operator gently pulls the first engaging member 121 to rotate the first engaging member 121 relative to the first housing 11 to a position where the second chip holder 2 can be removed away from the first housing 11, thereby releasing the engagement between the first chip holder 1 and the second chip holder 2. Figure 8 The first elastic member 123 shown is a spring, and the relative position between the first engaging member 121 and the first housing 11 is restored to a normal position, so that the second chip holder 2 is engaged with the first chip holder 1 again.

[0059] In other embodiments, the first elastic member 123 is a torsion spring, which is not shown in the drawings of this specification. Specifically, the torsion spring is arranged on the first rotating shaft 122, and one end of the torsion spring is connected to the first engaging member 121, and the other end is connected to the first housing 11, so that the torsion spring can use its elastic force to reset the first engaging member 121 and the first housing 11 to the above-mentioned normal position. In this embodiment, compared with the above-mentioned embodiment in which the first elastic member 123 is a spring, except for the different position of the first elastic member 123, the rest of the installation method and operation method are similar, and the description in the above-mentioned embodiment in which the first elastic member 123 is a spring can be referred to.

[0060] It should be noted that the first elastic member 123 may also be at least one spring or at least one torsion spring, one end of each of these springs or torsion springs is connected to the first engaging member 121 , and the other end of each of these springs or torsion springs is connected to the first housing 11 .

[0061] Regarding the engagement method between the first chip holder 1 and the second chip holder 2, in other embodiments, such as Figure 15-18 As shown, the second chip holder 2 includes a second housing 21 and a second clamping member 24, the second clamping member 24 includes a second clamping member 241, a second rotation shaft 242 and a second elastic member 243, the second rotation shaft 242 is connected to the second clamping member 241 and the second housing 21 and enables at least one of the second clamping member 241 and the second housing 21 to rotate around the second rotation shaft 242, one end of the second elastic member 243 is connected to the second clamping member 241, and the other end is connected to the second housing 21. The second clamping member 24 is used to clamp the first chip holder 1, so that the first chip holder 1 and the second chip holder 2 are connected together by clamping. More specifically, the second engaging member 241 is used to engage the first chip holder 1; the second rotating shaft 242 enables the second engaging member 241 to rotate relative to the second shell 21, so that when the second engaging member 241 is about to engage the first chip holder 1 and when the second engaging member 241 is released from engaging the first chip holder 1, the second engaging member 241 has a certain rotational movement space to reduce the wear of the second engaging member 241 and the first chip holder 1 caused by the friction between the second engaging member 241 and the first chip holder 1; the second elastic member 243 is used to reset the normal position between the second engaging member 241 and the second shell 21, wherein the normal position refers to the first chip holder 1 The relative position between the second engaging member 241 and the second shell 21 when the second chip seat 2 has not yet been engaged, the normal position is also the relative position between the second engaging member 241 and the second shell 21 after the first chip seat 1 and the second chip seat 2 are engaged together, and the normal position is also the position when the second engaging member 241 and the second shell 21 are in a stable state with respect to each other, that is, the relative rotation between the second engaging member 241 and the second shell 21 occurs in the process from when the first chip seat 1 and the second chip seat 2 are ready to engage to when the engagement is completed, or in the process from when the first chip seat 1 and the second chip seat 2 are ready to disengage from the engagement state to when the disengagement is completed.

[0062] Therefore, the first chip seat 1 and the second chip seat 2 are clamped together by the second clamping member 24, and the second clamping member 24 also includes a second clamping member 241, a second rotating shaft 242 and a second elastic member 243, which can reduce the wear of the second clamping member 241 and the first chip seat 1 during the process of clamping or releasing the first chip seat 1 and the second chip seat 2. At the same time, the second elastic member 243 can also reset the first chip seat 1 to a normal position between the second clamping member 241 and the second shell 21.

[0063] Furthermore, in some embodiments, the second elastic member 243 is a spring, such as Fig.18 As shown, one end of the spring is connected to the second engaging member 241 , and the other end of the spring is connected to the second housing 21 .

[0064] Therefore, when the first chip holder 1 and the second chip holder 2 are ready to be engaged, since the second engaging member 241 itself has a guiding slope, the second chip holder 2 can be more smoothly engaged to the engaged position (such as Figure 15-17 As shown in FIG. 2 , during this process, due to the existence of the second rotating shaft 242, that is, due to the relative rotation of the second engaging member 241 and the second housing 21, the second engaging member 241 will be subjected to the force from the first chip holder 1 and rotate relative to the second housing 21, so that the second chip holder 2 can be better engaged to the position when the engagement is completed. Fig.18 The second elastic member 243 shown is a spring, so that when the second chip holder 2 is inserted into the position where the engagement is completed (such as Fig.17 As shown in the figure, the relative position between the second engaging member 241 and the second shell 21 can be restored to a normal position. At this time, the second engaging member 241 can clamp the first chip holder 1, so that the second chip holder 2 is not easily separated from the first chip holder 1.

[0065] When the first chip holder 1 and the second chip holder 2 are ready to be released from engagement, the operator gently pulls the second engaging member 241 to rotate the second engaging member 241 relative to the second housing 21 to a position where the second chip holder 2 can be easily removed away from the first chip holder 1, thereby releasing the engagement between the first chip holder 1 and the second chip holder 2. Fig.18 The second elastic member 243 shown is a spring, and the relative position between the second engaging member 241 and the second housing 21 is restored to a normal position, so that the second chip holder 2 is engaged with the first chip holder 1 again.

[0066] In other embodiments, the second elastic member 243 is a torsion spring, which is not shown in the drawings of this specification. Specifically, the torsion spring is arranged on the second rotating shaft 242, and one end of the torsion spring is connected to the second engaging member 241, and the other end is connected to the second housing 21, so that the torsion spring can use its elastic force to reset the second engaging member 241 and the second housing 21 to the above-mentioned normal position. In this embodiment, compared with the above-mentioned embodiment in which the second elastic member 243 is a spring, except for the different position of the second elastic member 243, the rest of the installation method and operation method are similar, and the description in the above-mentioned embodiment in which the second elastic member 243 is a spring can be referred to.

[0067] It should be noted that the second elastic member 243 may also be at least one spring or at least one torsion spring, one end of each of these springs or torsion springs is connected to the second engaging member 241 , and the other end of each of these springs or torsion springs is connected to the second housing 21 .

[0068] In some embodiments, Figure 9-10 As shown, the second chip holder 2 includes a second shell 21, a third shaft 22 and a third elastic member 23. The third shaft 22 is connected to the first chip holder 1 and the second shell 21 and enables at least one of the second shell 21 and the first chip holder 1 to rotate around the third shaft 22. One end of the third elastic member 23 is connected to the second shell 21, and the other end is connected to the first chip holder 1. Fig.10 In the embodiment shown, the first chip holder 1 is fixed relative to the ground, and the second housing 21 rotates around the third rotation axis 22 relative to the first chip holder 1. Fig.10 In the illustrated embodiment, the third elastic member 23 is a torsion spring, which is disposed on the third rotating shaft 22 , and one end of the torsion spring is connected to the second housing 21 , and the other end of the torsion spring is connected to the first chip holder 1 .

[0069] Therefore, Fig. 9 As shown, when the first chip holder 1 and the second chip holder 2 are ready to be released from engagement, the operator gently pulls the first engaging member 121 to rotate the first engaging member 121 relative to the first housing 11 to a position where the second chip holder 2 is conveniently removed in a direction away from the first housing 11 (i.e., the operator moves the first chip holder 2 in a direction away from the first housing 11). Fig. 9 Gently push the first engaging member 121 counterclockwise to make the second chip holder 2 Fig. 9 In the middle direction, the third elastic member 23 ( Fig.10 The third elastic member 23 shown is a torsion spring, and the second chip holder 2 can be bounced away from the first chip holder 1, so that the first chip holder 1 and the second chip holder 2 are released from engagement.

[0070] It should be noted that the third elastic member 23 may also include at least one torsion spring, one end of each torsion spring is connected to the first chip holder 1, and the other end is connected to the second chip holder 2. The rest of the installation and operation methods can refer to the above description. Using multiple torsion springs as the third elastic member 23 can enhance the elastic force when the first chip holder 1 and the second chip holder 2 are released, so that the efficiency of releasing the first chip holder 1 and the second chip holder 2 is higher.

Further, the first cover 6 can be integrally formed with the first chip holder 1 or the second chip holder 2.
