Description

Technical Field

[0001] The present application relates to the field of testing technology, and in particular to a connection device, a setting method, a connector, and a testing machine for matching a floating interface. Background Art

[0002] The interface assembly of the tester is installed on the top of the test head. The interface assembly is mainly composed of an interface metal plate and an interface test board (PCB). The purpose of the interface assembly is to meet the needs of the interface test board (PCB) to connect with the corresponding external equipment such as the prober (probe station) or handler (sorter), and to transmit electrical signals through the electrical connection assembly between the two. Generally speaking, the tester and the external equipment are produced by different manufacturers. At the same time, the tester can match a variety of external equipment such as probers (probe stations) or handlers (sorters) specific to different manufacturers. However, due to the equipment's own assembly accuracy and the on-site installation environment, the reference position of the two when actually connected has a small angle of tilt compared to the theoretical reference plane. At the same time, due to the large mass of the tester itself, it also needs to be equipped with a corresponding arm bracket. In the limited space for docking with the external equipment, the entire equipment is difficult to move conveniently. Due to the above two reasons, high-end testing machines often use floating interface plates in the design of interface components, and add elastic devices below the floating interface plates to achieve small-angle tilt adaptation on the docking plane, small-angle rotation on the XY plane, and translation adaptation in the Z direction, which can more conveniently and quickly match the corresponding external equipment.

[0003] Although the setting of the floating interface board increases the ease of docking the test machine, it also increases the difficulty of designing the connection device that matches the floating interface. The test machine will be equipped with different numbers and types of resource boards according to the device under test, user needs, etc. The resource boards are inserted into the test machine along the corresponding guide structure and finally fixed inside the test machine. The characteristic of these resource boards is that they have external connectors of consistent shape at the output end. If the test machine adopts a non-floating interface board setting, the resource board can directly achieve the adaptation of the output connector of the resource board to the connector or metal contact on the interface test board (PCB) through mechanical hard connection. However, if the test machine adopts a floating interface board setting, the entire interface board assembly is an elastic movable structure with multiple degrees of freedom. In this case, the resource board cannot be adapted to this structure through mechanical hard connection.

[0004] Therefore, how to connect the resource board and the interface test board when the test machine adopts a floating interface board has become an urgent problem to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] Example 1

[0035] In order to solve the problem in the related art that the resource board and the interface test board cannot be connected when the test machine adopts a floating interface, the present application provides a connection device that matches the floating interface, such as Figure 1 As shown, the connecting device 11 matching the floating interface (connecting device 11 matching the floating interface Figure 1 Not shown, such as Figure 5As shown) includes: a connector, a detachable fixing member; the connector includes: a flexible conductive component 1 and a non-flexible conductive component 2; wherein, one end of the flexible conductive component 1 is connected to the tail of the non-flexible conductive component 2, the other end of the flexible conductive component 1 is connected to the resource board 3, and the head of the non-flexible conductive component 2 passes through the floating interface 9 (floating interface 9 Figure 1 Not shown, such as Figure 5 As shown) through-hole and interface test board 13 (interface test board 13 Figure 1 Not shown, such as Figure 5 the detachable fixing members are respectively connected to the non-flexible conductive component 2 and the resource board 3, for fixing the non-flexible conductive component 2 on the resource board 3.

[0036] It is understandable that this embodiment does not limit the connection method between the other end of the flexible conductive component 1 and the resource board 3. For example, the connection method between the other end of the flexible conductive component 1 and the resource board 3 includes but is not limited to: at least one of welding, flange connection, thread connection, socket connection and groove clamp. Among them, the connection method between one end of the flexible conductive component 1 and the tail of the non-flexible conductive component 2 is also not limited. In some examples, the flexible conductive component 1 includes: any connector with soft or bendable properties and capable of electrical transmission, such as a flexible connecting wire, a flexible printed circuit board and a flexible connecting strip, and the non-flexible conductive component 2 includes any one of a socket, a gold finger and a probe. The non-flexible conductive component 2 is preferably a connector with a probe.

[0037] Among them, in order to enable the resource board 3 and the non-flexible conductive component 2 to be relatively fixed when the connector is set to connect the resource board 3 and the interface test board 13, and to facilitate the connection between the non-flexible conductive component 2 of the connector and the interface test board 13, the non-flexible conductive component 2 needs to be fixed in advance, and the flexible conductive component 1 connected to the resource board 3 is flexible and can be bent arbitrarily, so the flexible conductive component does not have a supporting force and cannot fix the non-flexible conductive component 2 and the resource board 3 relatively. Therefore, the connection device 11 matching the floating interface provided in this example is also provided with a detachable fixing part, which is connected to the output end housing of the non-flexible conductive component 2 and the resource board 3 respectively through the detachable fixing part to achieve the fixation of the non-flexible conductive component 2 relative to the resource board 3. The non-flexible conductive component 2 is fixed relative to the resource board 3 and does not move, which is convenient for the subsequent connection between the non-flexible conductive component 2 and the interface test board 13. The non-flexible conductive component is fixed relatively to the resource board 3 by the installed detachable fixing parts, and the non-flexible conductive component 2 of the connector is connected to the interface test board 13 through the floating interface 9. After removing the above-mentioned detachable fixing parts, the connector is connected to the interface test board 13 through the non-flexible conductive component 2 and establishes a connection with the resource board 3 through the flexible conductive component 1, thereby realizing a floating connection between the resource board 3 and the interface test board 13 when the test machine 12 uses the floating interface 9, and avoiding the problem in the related technology that the resource board 3 and the interface test board 13 cannot be connected when the test machine 12 adopts the floating interface 9.

[0038] The connection device 11 for matching the floating interface provided in this example is provided with a connector and a detachable fixing part. The non-flexible conductive component 2 is relatively fixed on the resource board 3 through the detachable fixing part, and the non-flexible conductive component 2 of the connector passes through the floating interface 9 and is connected to the interface test board 13, thereby realizing the connection between the resource board 3 and the interface test board 13 when the test machine 12 uses the floating interface 9, avoiding the problem in the related art that the resource board 3 and the interface test board 13 cannot be connected when the test machine 12 adopts the floating interface 9.

[0039] In some examples of this embodiment, the connector further includes: a non-flexible conductive component housing 4, wherein a plurality of through-holes are provided on the non-flexible conductive component housing 4, the non-flexible conductive component 2 is fixed through the through-holes of the non-flexible conductive component housing 4, and the head of the non-flexible conductive component 2 is exposed outside the non-flexible conductive component housing 4; the shape of the non-flexible conductive component housing 4 matches the shape of the through-holes of the floating interface 9, and the non-flexible conductive component housing 4 at least partially passes through the floating interface 9, so that the head of the non-flexible conductive component 2 is connected to the interface test board 13. Specifically, taking the non-flexible conductive component 2 as a probe as an example, as shown in FIG. Figure 1As shown, the non-flexible conductive component housing 4 is provided with a plurality of through-holes, each of which is used to accommodate a non-flexible conductive component 2 ( Figure 1 Only a portion of the non-flexible conductive component 2 is shown as an example, and the head of the non-flexible conductive component 2 is exposed outside the non-flexible conductive component housing 4. In addition, the shape of the non-flexible conductive component housing 4 matches the shape of the perforation of the floating interface 9, allowing at least a portion of the non-flexible conductive component housing 4 to pass through the perforation of the floating interface 9, thereby allowing the non-flexible conductive component 2 disposed within the non-flexible conductive component housing 4 to pass through the floating interface 9 and connect to the interface test board 13. The non-flexible conductive component housing 4 not only protects the non-flexible conductive component 2, but also serves as a base for supporting the non-flexible conductive component 2.

[0040] Continuing with the above example, specifically, for example, the shape of the perforation of the floating interface 9 is rectangular. At this time, the shape of the end face of the non-flexible conductive component shell 4 close to the floating interface 9 is also rectangular, and the rectangular area of ​​the non-flexible conductive component shell 4 is smaller than the rectangular area of ​​the perforation of the floating interface 9, thereby allowing the non-flexible conductive component shell 4 to at least partially pass through the perforation of the floating interface 9; for another example, the shape of the perforation of the floating interface 9 is circular. At this time, the shape of the end face of the non-flexible conductive component shell 4 close to the floating interface 9 is also circular, and the circular area of ​​the non-flexible conductive component shell 4 is smaller than the circular area of ​​the perforation of the floating interface 9, thereby allowing the non-flexible conductive component shell 4 to pass through the perforation of the floating interface 9.

[0041] In some examples of this embodiment, the detachable fixing member includes: a retaining member 5; the retaining member 5 is used to maintain the movement direction of the non-flexible conductive component housing 4 relative to the resource board 3, so that the movement direction of the non-flexible conductive component housing 4 on the retaining member 5 is the same as the connection direction of the connector to the resource board 3. The retaining member 5 is fixed to the resource board 3 and contacts the connector, so that the retaining member 5 can fix the movement direction of the non-flexible conductive component housing 4, so that the movement direction of the non-flexible conductive component housing 4 on the retaining member 5 is parallel to the connection direction between the connector and the resource board 3. It can be understood that the retaining member 5 can also be used to limit the movement range of the non-flexible conductive component housing 4, that is, the movement range of the non-flexible conductive component housing 4 is the length of the retaining member 5;

[0042] Continuing with the above example, this embodiment does not limit the setting method of the retaining member 5, which can be flexibly set by relevant personnel. For better understanding, this embodiment provides several examples to illustrate the retaining member 5. For example, the retaining member 5 is a hand screw, which is arranged on the side of the output end shell of the resource board 3 close to the connector, and a U-shaped opening corresponding to the hand screw is provided on the non-flexible conductive component shell 4. The moving direction of the non-flexible conductive component shell 4 and the moving range of the non-flexible conductive component shell 4 are limited by the hand screw and the U-shaped opening, so that the moving direction of the non-flexible conductive component shell 4 is the same as the connection direction of the connector connecting the resource board 3, and the moving range of the non-flexible conductive component shell 4 does not exceed the hand screw. length; for another example: the retaining member 5 includes: a slide rail and a slide groove, the slide groove is fixed on the non-flexible conductive component shell 4, the slide rail is arranged on the side of the output end shell of the resource board 3 close to the connector, and the sliding direction of the slide rail is the same as the connection direction of the connector connecting the resource board 3, the non-flexible conductive component shell 4 moves on the slide rail through the slide groove, thereby limiting the moving direction of the non-flexible conductive component shell 4 to be the same as the connection direction of the connector connecting the resource board 3. At the same time, in order to avoid the slide groove from rotating when moving on the slide rail, two slide rails can be provided to fix the slide groove, or it can be provided with slide rails of other shapes, for example, rectangular slide rails, to fix the slide groove.

[0043] In some examples of this embodiment, such as Figure 2 As shown, the detachable fixing member also includes: a first limiting member 8; the first limiting member 8 is fixed on the non-flexible conductive component housing 4, and the first limiting member 8 cooperates with the retaining member 5 to limit the distance between the non-flexible conductive component housing 4 and the resource board 3. In order to enable the subsequent resource board 3 to better match the floating interface 9 through the connector, it is necessary to limit the distance between the non-flexible conductive component housing 4 and the resource board 3, so that there is a floating position between the non-flexible conductive component housing 4 and the resource board 3. Therefore, this example provides a first limiting member 8, which limits the distance between the non-flexible conductive component housing 4 and the resource board 3 when it moves. In some examples, the distance between the non-flexible conductive component housing 4 and the resource board 3 is greater than the sum of the thickness of the interface metal plate and the floating interface 9;

[0044] Continuing with the above example, the first limiting member 8 provided in this example includes but is not limited to: a limiting bar; taking the first limiting member 8 as a limiting bar as an example, the limiting bar is arranged on the side of the head of the non-flexible conductive component shell 4 where the non-flexible conductive component 2 is exposed, and the limiting bar is used to limit the non-flexible conductive component shell 4 from sliding, thereby limiting the distance between the non-flexible conductive component shell 4 and the resource board 3. It can be understood that the first limiting member 8 is arranged on the side of the head of the non-flexible conductive component shell 4 where the non-flexible conductive component 2 is exposed, thereby facilitating the removal of the first limiting member 8 after the non-flexible conductive component shell 4 is perforated through the floating interface 9.

[0045] In some examples of this embodiment, the connection device 11 matching the floating interface further includes a protective cover 7, which is disposed on the side of the non-flexible conductive component housing 4 where the head portion is exposed. The protective cover 7 is used to protect the exposed head portion. To prevent damage to the head portion before connection to the interface test board 13, this embodiment further provides a protective cover 7, which is disposed on the side of the non-flexible conductive component housing 4 where the head portion is exposed, thereby protecting the exposed head portion.

[0046] In some examples of this embodiment, a locking piece 6 is further provided on the non-flexible conductive component housing 4. The locking piece 6 is used to cooperate with the floating interface 9 to fix the non-flexible conductive component housing 4 when the non-flexible conductive component housing 4 passes through the floating interface 9. The locking piece 6 is provided on the non-flexible conductive component housing 4, and the position of the locking piece 6 corresponds to the position of the locking piece on the floating interface 9, thereby enabling the non-flexible conductive component housing 4 to be fixed on the floating interface 9 after the non-flexible conductive component housing 4 passes through the floating interface 9.

[0047] Following the above example, for example, the non-flexible conductive component housing 4 is rectangular, and the locking members 6 are arranged on opposite sides of the rectangular non-flexible conductive component housing 4, and as shown in FIG. Figure 2 As shown, the floating interface 9 is provided with an inverted L-shaped mounting plate as a fixing member, and the inverted L-shaped mounting plate is provided with a fixing hole 10, and taking the fixing hole provided on the locking member 6 as an example, as shown in FIG. Figure 3 As shown, when the non-flexible conductive component housing 4 passes through the through hole of the floating interface 9, the locking member 6 contacts the inverted L-shaped mounting plate, as shown in FIG. Figure 4 As shown, after the fixing holes on the locking member 6 are aligned with the fixing holes on the inverted L-shaped mounting plate, bolts are passed through the fixing holes of the locking member 6 and the fixing holes 10 of the L-shaped mounting plate to fix the locking member 6 and the floating interface 9, thereby achieving the fixation of the non-flexible conductive component housing 4 through the cooperation between the locking member 6 and the floating interface 9.

[0048] The connection device 11 for matching the floating interface provided in this example includes: a connector, a detachable fixing part; the connector includes: a flexible conductive component 1 and a non-flexible conductive component 2; wherein, one end of the flexible conductive component 1 is connected to the tail of the non-flexible conductive component 2, the other end of the flexible conductive component 1 is connected to the resource board 3, and the head of the non-flexible conductive component 2 passes through the perforation of the floating interface 9 and is connected to the interface test board 13; the detachable fixing part is respectively connected to the non-flexible conductive component 2 and the resource board 3, and is used to relatively fix the non-flexible conductive component 2 on the resource board 3. The connection device 11 for matching the floating interface provided in this example is provided with a connector and a detachable fixing part. The non-flexible conductive component 2 is relatively fixed on the resource board 3 by the detachable fixing part, and is connected to the interface test board 13 through the floating interface 9 through the non-flexible conductive component 2 of the connector. After removing the above-mentioned detachable fixing part, the connector is connected to the interface test board through the non-flexible conductive component and to the resource board through the flexible conductive component, thereby realizing a multi-angle floating connection between the resource board 3 and the interface test board 13 when the test machine 12 uses the floating interface 9 that can float at multiple angles, and avoiding the problem in the related art that the resource board 3 and the interface test board 13 cannot be connected when the test machine 12 adopts the floating interface 9.

[0049] Example 2

[0050] In order to better understand the present invention, this embodiment provides a more specific example for illustration:

[0051] like Figure 5 As shown, Figure 5 This is a basic diagram of a resource board (including a connection device) before insertion. This example provides a connection device 11 that matches the floating interface. This device can be used between the resource board 3 and the floating interface 9 component. This connection device has a simple structure, saves assembly space, and reduces the number of electrical connection nodes.

[0052] Specifically, the connecting device 11 provided in this example, which can match the floating interface, is used to establish a floating connection between the resource board 3 and the interface test board 13 (PCB), so as to implement testing of the device under test on the interface test board 13 (PCB) assembly through the resource board 3. The connecting device includes:

[0053] The connector includes a flexible conductive component 1 and a non-flexible conductive component 2, wherein one end of the flexible conductive component 1 is connected to the resource board 3 to realize the electrical connection between the connector and the resource board 3 in a flexible manner, and the other end of the flexible conductive component 1 is connected to the tail of the non-flexible conductive component 2, and the head of the non-flexible conductive component 2 can contact the metal contact of the interface test board 13 (PCB) to realize the transmission path of the electrical signal; it can be understood that the connector also includes: a non-flexible conductive component shell 4, a plurality of perforations are provided on the non-flexible conductive component shell 4, the non-flexible conductive component 2 is fixed through the perforations of the non-flexible conductive component shell 4, and the head of the non-flexible conductive component 2 is exposed outside the non-flexible conductive component shell 4; the shape of the non-flexible conductive component shell 4 matches the perforation shape of the floating interface 9, and the non-flexible conductive component shell 4 passes through the floating interface 9, so that the head of the non-flexible conductive component 2 contacts the metal contact of the interface test board 13 (PCB) to realize the transmission path of the electrical signal. Wherein, as Figure 6 As shown, Figure 6 This is a basic schematic diagram after the resource board (including the connection device) is inserted into place.

[0054] The connection device 11 provided in this example, which can match the floating interface, further includes: a retaining member 5, which is a hand-tightening screw and is detachably disposed between the output end housing of the resource board 3 and the connector. Before the resource board 3 is inserted into the test machine 12, the retaining member 5 is ensured to be fixed in a relative position of the connector on a plane perpendicular to the insertion direction. After the resource board 3 is inserted into the test machine 12 and a connection is established therewith, the retaining member 5 needs to be removed through an assembly step.

[0055] This example provides a connection device 11 that can match a floating interface, wherein the non-flexible conductive component housing 4 has two U-shaped openings on both sides, and the retaining member 5 is a rod-shaped structure with a straight groove and knurling on the head to facilitate assembly operation. The U-shaped opening cooperates with the retaining member 5 to limit the non-flexible conductive component housing 4, so that the relative position of the non-flexible conductive component housing 4 on a plane perpendicular to the insertion direction is fixed. However, this state currently lacks limit, and the connector will move freely on the rod-shaped structure, and it cannot ensure that the preset distance between the connector and the housing where the resource board 3 is located is maintained. Therefore, a limit strip is added to this structure. The purpose of the limit strip is to ensure that the preset distance between the connector and the housing where the resource board 3 is located is maintained by limiting. The limit is achieved by fixing the two mounting holes of the connector with two screws on the locking strip that cannot be removed, and the bottom of the locking strip is in contact with the head of the retaining member 5.

[0056] With such arrangement, when the resource board 3 component itself is in an independent state, the connecting device can be installed on the resource board 3 component in a relatively fixed position, and the structural connection is simple and easy to process.

[0057] The connection device 11 provided in this example can match the floating interface, and the preset distance (A) between the resource board 3 shell and the connector must be greater than the sum of the average thicknesses of the interface metal plate and the L-shaped mounting plate.

[0058] With such an arrangement, a certain distance can be maintained between the resource board 3 and the connector. At this time, when the interface test board 13 deflects at a small angle, it will not collide with the resource board 3 .

[0059] In this example, the floating interface-compatible connection device 11 includes a housing positioned near the lower end of the connector. The housing has a hollow channel. This arrangement allows the housing to restrain and constrain cables, preventing them from being damaged by scraping against other resource boards during insertion and removal.

[0060] In the connection device 11 provided in this example that can match the floating interface, the cable length of the flexible conductive component 1 should be greater than the preset distance. The reserved cable length can meet the maximum connection length of the floating interface 9 in multiple degrees of freedom.

[0061] like Figure 4 As shown, the connection device 11 provided in this example that can match the floating interface further includes: a first limiting member 8, which is a limiting bar. The limiting bar is arranged above the non-flexible conductive component housing 4 of the connector. When the limiting bar is in the installed state, it plays a limiting role, which can maintain a preset distance between the non-flexible conductive component housing 4 and the output end housing of the resource board 3 along the insertion direction;

[0062] The floating interface 9 is a metal plate, and has an opening that allows the non-flexible conductive component housing 4 to at least partially pass through, and also has a fixed connection portion for fixing the non-flexible conductive component housing 4, such as Figure 7 As shown, the fixed connection portion of the floating interface 9 includes: an inverted L-shaped mounting plate for fixing the connector, and the inverted L-shaped mounting plate has an opening for avoiding the head of the retaining member 5. Among them, the connection device 11 that can match the floating interface provided in this example, the L-shaped mounting plate of the floating interface 9 is fixed above the interface test board 13, and the L-shaped mounting plate is arranged on both sides corresponding to the connector, and has an opening in the middle area to avoid the retaining portion. In the process of inserting the guide slot of the resource board 3 into the test machine 12, when the upper contact surface of the connector body fits with the lower contact surface of the L-shaped mounting plate, the resource board 3 is in the installation stage. As shown Figure 8 As shown, Figure 8 This is a basic schematic diagram of the installation of the L-shaped mounting plate of the floating interface and the non-flexible conductive component housing. After all the installations are completed, the resource board 3 and the interface test board 13 are connected through the connecting device and floated with the floating interface 9, as shown in FIG. Figure 9 shown.

[0063] The connection device 11 provided in this example that can match the floating interface further includes: a protective cover 7, which is arranged above the non-flexible conductive component 2 of the connector and can protect the non-flexible conductive component 2 during the assembly process.

[0064] Advantages of a connecting device 11 matching a floating interface:

[0065] First, while the resource board 3 assembly itself is being examined, the connection device can be mounted on the resource board 3 assembly in a relatively fixed position. The resource board 3 can be blindly inserted through the guide slots on the test head of the tester 12. Furthermore, if the resource board 3 needs to be replaced or maintained, it can be directly removed through the guide slots. This connection device offers excellent maintainability and convenient replacement, eliminating the tedious assembly steps of disassembling the entire test head.

[0066] Second, within the conveniently accessible exterior space of tester 12, a specific assembly sequence allows the connector assembly with its wiring harness to be transferred to the interface metal plate, effectively matching the multi-degree-of-freedom floating interface 9. This approach avoids the need for a larger internal assembly space in conventional testers 12 to accommodate the floating interface 9.

[0067] Third, the force on the resource board 3 is improved. This method transfers the force of the output connector assembly (Pogo block) from the single board end (the resource board itself) to the interface metal plate end. Compared with the test machine 12 with a non-floating interface 9, the force is concentrated on the end of the resource board 3. This method disperses the mechanical distribution, reducing the difficulty of designing the mechanical characteristics of the plug-in and pull-out aid device at the end of the resource board 3.

[0068] Example 3

[0069] Based on the same concept, this embodiment also provides a connector, which includes: a flexible conductive component 1 and a non-flexible conductive component 2; wherein,

[0070] One end of the flexible conductive component 1 is connected to the tail of the non-flexible conductive component 2, the other end of the flexible conductive component 1 is used to connect to the resource board 3, and the head of the non-flexible conductive component 2 is used to pass through the through hole of the floating interface 9 and connect to the interface test board 13.

[0071] In some examples of this embodiment, the connector also includes: a non-flexible conductive component shell 4, a plurality of perforations are provided on the non-flexible conductive component shell 4, the non-flexible conductive component 2 is fixed through the perforations of the non-flexible conductive component shell 4, and the head of the non-flexible conductive component 2 is exposed outside the non-flexible conductive component shell 4; the shape of the non-flexible conductive component shell 4 matches the perforation shape of the floating interface 9, and the non-flexible conductive component shell 4 passes through the floating interface 9, so that the head of the non-flexible conductive component 2 is connected to the interface test board 13.

[0072] In some examples of this embodiment, a locking piece 6 is also provided on the non-flexible conductive component shell 4. The locking piece 6 is used to cooperate with the floating interface 9 to fix the non-flexible conductive component shell 4 when the non-flexible conductive component shell 4 passes through the floating interface 9.

[0073] Example 4

[0074] Based on the same concept, this embodiment also provides a method for setting a connection device that matches a floating interface, such as Figure 10 As shown, the method includes:

[0075] S101, connecting one end of a flexible conductive component of a connector to a resource board, and connecting the other end of the flexible conductive component to a tail of a non-flexible conductive component in the connector;

[0076] S102, fixing the connector relatively to the resource board by a detachable fixing member;

[0077] S103, passing the head of the non-flexible conductive component through the through-hole of the floating interface and connecting it to the interface test board;

[0078] S104: Remove the detachable fixing member, so that the connector matches the floating interface and floats.

[0079] In which, the connector also includes: a non-flexible conductive component shell, a plurality of perforations are provided on the non-flexible conductive component shell, the non-flexible conductive component is fixed through the perforations of the non-flexible conductive component shell, and the head of the non-flexible conductive component is exposed outside the non-flexible conductive component shell; the shape of the non-flexible conductive component shell matches the perforation shape of the floating interface, and the non-flexible conductive component shell partially passes through the floating interface, so that the head of the non-flexible conductive component is connected to the interface test board.

[0080] In some examples, the detachable fixing member includes: a retaining member; the connector is relatively fixed to the resource board card by the detachable fixing member, including: a retaining member is provided between the connector and the resource board card; the retaining member is used to maintain the movement direction of the non-flexible conductive component housing, so that the movement direction of the non-flexible conductive component housing on the retaining member is the same as the connection direction of the connector to the resource board card. The retaining member is fixed to the resource board card and contacts the connector, so that the retaining member can fix the movement direction of the non-flexible conductive component housing, so that the movement direction of the non-flexible conductive component housing on the retaining member is parallel to the connection direction between the connector and the resource board card. It can be understood that the retaining member can also be used to limit the movement range of the non-flexible conductive component housing, that is, the movement range of the non-flexible conductive component housing is the length of the retaining member;

[0081] In some examples, the detachable fixing member further includes: a first limiting member; the connector is relatively fixed to the resource board card by the detachable fixing member, and further includes: a first limiting member is provided on the side of the non-flexible conductive component shell where the head of the non-flexible conductive component is exposed, wherein the first limiting member is fixed to the non-flexible conductive component shell, and the first limiting member cooperates with the retaining member to limit the distance between the non-flexible conductive component shell and the resource board card. Specifically, in order to enable the subsequent resource board card to better match the floating interface through the connector, it is necessary to limit the distance between the non-flexible conductive component shell and the resource board card so that there is a floating position between the non-flexible conductive component shell and the resource board card. Therefore, this example provides a first limiting member, which limits the distance between the non-flexible conductive component shell and the resource board card when it moves. In some examples, the distance between the non-flexible conductive component shell and the resource board card is greater than the sum of the thickness of the interface metal plate and the floating interface;

[0082] In some examples, the connection device for matching the floating interface further includes a protective cover that secures the connector relative to the resource board via a removable fastener, and a protective cover disposed on the side of the non-flexible conductive component housing where the head of the non-flexible conductive component is exposed, the protective cover being configured to protect the exposed head of the non-flexible conductive component. To prevent damage to the head before connection to the interface test board, this example further provides a protective cover disposed on the side of the non-flexible conductive component housing where the head is exposed, thereby protecting the exposed head.

[0083] In some examples, the non-flexible conductive component housing is further provided with a locking member, which is used to cooperate with the floating interface to secure the non-flexible conductive component housing when the non-flexible conductive component housing passes through the floating interface. The fixing member is provided on the non-flexible conductive component housing, and the position of the locking member corresponds to the position of the fixing member on the floating interface, thereby enabling the non-flexible conductive component housing to be secured to the floating interface after the non-flexible conductive component housing passes through the floating interface.

[0084] In some examples of this embodiment, the detachable fixing member is removed so that the connector matches and floats with the floating interface, including: removing the retaining member provided between the connector and the resource board; removing the first limiting member provided on the side of the non-flexible conductive component shell that exposes the head of the non-flexible conductive component; removing the protective cover provided on the side of the non-flexible conductive component shell that exposes the head of the non-flexible conductive component, thereby achieving the matching and floating of the connector with the floating interface.
