Description

Technical Field

[0001] This case relates to a sliding auxiliary connection assembly, and more particularly to a sliding auxiliary connection assembly for sliding connection and locking of an electronic device, such as a network card. Prior Technology

[0002] The slide rail structure is a well-known technology used for the insertion or removal of two electronic devices to form an electrical connection or disconnection.

[0003] Figure 1 shows an exploded perspective view of a first embodiment of a removable electronic device. The removable electronic device includes a host 10, such as a server, and a removable component 20, such as a network card. The host 10 includes a first plate 101, such as a motherboard, having a connector 102. A pair of fixed rails 103 are provided on opposite sides of the connector 102, and each fixed rail 103 has a groove 104. The removable component 20 has a second plate 201, such as a circuit board (shown in Figure 2). A connector plug (not shown due to projection angle) is provided on the inner side of the second plate 201 corresponding to the connector 102, and a pair of sliding rails 202 extend opposite sides of the second plate 201, each sliding rail 202 having a locking hole 203.

[0004] When the extractor 20 is to be attached to the host 10, the user only needs to insert the pair of sliding rails 202 into the pair of rail grooves 104 of the pair of fixed rails 103 and slide it inward along the pair of rail grooves 104 until the connector plug is inserted into the connector 102 to form an electrical connection.

[0005] As shown in Figure 2, the configuration of the first plate 101 and the second plate 201 is such that the pair of fixed rails 103 are installed facing each other and spaced apart on the top surface of the first plate 101, while the second plate 201 is inserted between the pair of fixed rails 103 and located above the first plate 101, so that the second plate 201 forms a plate-like structure relative to the first plate 101.

[0006] Figure 3 shows an exploded perspective view of a second embodiment of a conventional removable electronic device. This removable electronic device includes a host 10, such as a server, and a removable component 20, such as a network card. The host 10 includes a first substrate 101, such as a motherboard, which has a rectangular hole 105. A connector 102 is mounted inside the hole 105, and a pair of fixed rails 103 are provided on opposite sides of the hole 105, each with a groove 104. The removable component 20 has a second substrate 201, such as a circuit board (shown in Figure 4). A connector plug (not shown due to projection angle) is provided on the inner side of the second substrate 201 corresponding to the connector 102, and a pair of sliding rails 202 extend opposite sides of the second substrate 201, each with a locking hole 203.

[0007] When the extractor 20 is to be attached to the host 10, the user only needs to insert the pair of sliding rails 202 into the pair of rail grooves 104 of the pair of fixed rails 103 and slide it inward along the pair of rail grooves 104 until the connector plug is inserted into the connector 102 to form an electrical connection.

[0008] As shown in Figure 4, the configuration of the first plate 101 and the second plate 201 is such that the pair of fixed rails 103 are installed opposite each other and spaced apart on both sides of the plate hole 105, while the second plate 201 is inserted into the plate hole 105 between the pair of fixed rails 103, so that the second plate 201 forms a plate-in-plate shape relative to the first plate 101.

[0009] However, the fixed rails 103 in the two embodiments described above do not have locking and positioning functions. Therefore, the connection and fixation between the host 10 and the extraction component 20 rely solely on the clamping force between the connector 102 and the connecting plug. If the host 10 is in a vibrating environment, the connector 102 and the connecting plug will become loose, resulting in a loss of electrical connection, which urgently needs improvement. Summary of the Invention

[0010] The main objective of this invention is to provide a sliding auxiliary connection assembly, which has a pair of fixed rails that can be mounted on or in the middle of a first plate, and at least one fixed rail is provided with a locking mechanism that manually locks the locking hole at a preset locking hole position on a second plate. This allows a pull-out component, such as a network card, containing the second plate (e.g., a circuit board), to manually lock and position a host, such as a server, containing the first plate (e.g., a motherboard), during the sliding of the pair of fixed rails, preventing the pull-out component from detaching from the host and ensuring the stability of the electrical connection.

[0011] To achieve the aforementioned objectives, the technical means adopted in this case is to provide a sliding auxiliary connection assembly, which includes a slide rail device. The slide rail device includes a first fixed rail and a second fixed rail spaced apart on a first plate. The fixed rails have a pair of axially formed grooves on opposite sides for the sliding rails on both sides of a second plate to pass through and slide. The first fixed rail protrudes from a locking hole in the opposite sliding rail, providing a positioning tower for mounting a locking member. The positioning tower includes a receiving groove with an opening above and a first bolt hole facing each other above and below, respectively. The first bolt hole communicates with one of the track grooves. The positioning tower further includes a hinge member at its bottom. A locking member includes a body with a first bolt extending from its bottom. The first bolt can radially extend out of the first bolt hole, and the contact surface between the body and the bottom of the positioning tower is provided with an elastic telescopic mechanism.

When the locking member is pressed, the elastic telescopic mechanism stores or releases energy, and the limiting mechanism defines the limitation of the radial displacement of the locking member in the positioning tower. The at least one guide tenon is displaced in the corresponding track mechanism according to a predetermined stroke, so that the first bolt passes through the first bolt hole and through the locking hole located in the track groove to form a locking state; or the first bolt disengages from the locking hole in the track groove and retracts into the first bolt hole to form an unlocking state.

[0012] In one embodiment, a side wing is radially protruding from the bottom of the opposite side of the first fixed rail and the second fixed rail, and the side wing includes at least one locking hole; wherein each locking hole is for a locking member to pass through and be screwed into a corresponding through hole provided on the first plate.

The slide rail device includes a centrally located first fixed rail spaced apart on a first plate and a pair of second fixed rails spaced apart on either side of the first fixed rail. Two pairs of rail grooves are axially formed on both sides of the first fixed rail and on the opposite side of the pair of second fixed rails, and each pair of rail grooves allows a pair of sliding rails on both sides of the second plate to pass through and slide. The first fixed rail corresponds to one of the two sliding rails. A positioning tower is provided at the locking hole location for mounting the locking member. The positioning tower includes a receiving groove, with an opening and a first bolt hole and a second bolt hole respectively formed on the upper and lower sides of the receiving groove, and each of the bolt holes communicates with a corresponding rail groove. The positioning tower further includes a hinge member at its bottom; and a locking member, which includes a body, with a first bolt and a second bolt extending from each of the two side walls of the body.

A limiting mechanism is also provided on at least one side wall of the positioning tower opposite to the side wall of the main body. A positioning device is provided on the main body corresponding to the hinge position. The positioning device includes a swing member pivotally connected to the hinge, at least one guide tenon extending inward from the swing member, and at least one track mechanism with a height difference forming a two-stage positioning on the side wall of the main body corresponding to the at least one guide tenon. When the locking member is pressed, the elastic telescopic mechanism stores energy. Alternatively, the locking mechanism may be used to limit the radial displacement of the locking member within the positioning tower, and the at least one guide tenon may be displaced according to a predetermined stroke in the corresponding track mechanism, causing the first bolt and the second bolt to pass through their respective first bolt holes and second bolt holes, and respectively through the locking holes located in one of the track grooves, to form a locking state; or the first bolt and the second bolt may be disengaged from the locking holes in one of the track grooves and retracted into their respective first bolt holes and second bolt holes, to form an unlocking state.

[0016] In one embodiment, the bottom surface of the first fixed rail is provided with at least one bottom connection hole at intervals, and the bottom of the opposite side of the second fixed rail is provided with a side wing radially protruding, the side wing including at least one locking hole; wherein each bottom connection hole and each locking hole is for a locking member to pass through and be screwed into a corresponding through hole provided on the first plate.

[0017] In one embodiment, the at least one locking hole is selectively provided on a plurality of radially extending protrusions of each of the side wings.

[0021] In one embodiment, the bottom surfaces of the first fixed rail and the second fixed rail each have at least one positioning tenon protruding; wherein each positioning tenon is inserted into a positioning hole correspondingly provided on the first plate.

[0022] In one embodiment, the limiting mechanism includes at least one limiting groove disposed opposite to a side wall of the positioning tower corresponding to the body, and a stop tenon sleeved in each limiting groove, so as to define the radial displacement stroke of the locking member in the positioning tower and prevent the locking member from coming out of the opening of the positioning tower.

[0023] In one embodiment, each of the tenons has a downwardly chamfered guide surface to facilitate fitting into the corresponding limiting groove.

Implementation

[0028] As shown in Figures 5a to 11, the first embodiment of the sliding auxiliary connection component of this case is basically an insulator integrally molded from plastic injection molding, which includes a slide rail device 1 and a locking member 2.

[0029] The slide rail device 1 includes a first fixed rail 11 and a second fixed rail 12 spaced apart. Each of the first fixed rail 11 and the second fixed rail 12 has an axially formed groove 13 on one of its opposing sides. To facilitate the insertion of a pair of sliding rails 202 (shown in FIG. 13) of an extractor 20 into the grooves 13, at least two walls at at least one end of each groove 13 form a guide opening 131 that tapers towards the center. Furthermore, each of the first fixed rail 11 and the second fixed rail 12 (not shown) has at least one positioning tenon 132 protruding from its bottom surface to facilitate insertion into a corresponding positioning hole 108 (shown in FIG. 12) on a first plate 101 of the main unit 10.

[0030] A side wing 14 is radially protruding from the bottom of the opposite side of the first fixed rail 11 and the second fixed rail 12. The purpose of the side wing 14 is that it can be directly mounted on a first plate 101 of a removable electronic host 10, such as the host plate, to form a plate-on-plate configuration; or the side wing 14 can abut against an inner bottom surface of a rectangular plate hole 105 pre-set in a first plate 101 of a host 10 (shown in Figures 12 and 13) to form a plate-on-plate configuration.

[0031] Please refer to Figures 5a and 5b. The side wing 14 includes at least one locking hole 141, and each locking hole 141 is for a conventional locking component, such as a screw, to pass through and be screwed into a pre-set through hole in the first plate 101. The at least one locking hole 141 is selectively provided on a plurality of radially extending protrusions 142 of the side wing 14. As shown, there are two locking holes 141, each located on the protrusion 142 at one end.

[0032] Furthermore, the head section below the rail groove 13 forms a clearance groove 15, the main function of which is to provide clearance space for an exit plate (not shown in the conventional diagram) of the extractor 20.

[0033] Furthermore, a positioning tower 16 is provided on the top surface of the first fixed rail 11 at the position of a locking hole 203 opened in a pair of sliding rails 202 at the bottom of the extraction member 20, for mounting the locking member 2. The positioning tower 16 has a receiving groove 161 (shown in Figure 6a, and for ease of explanation, one inner sidewall of the positioning tower 16 is deleted). An opening 162 and a first bolt hole 163 are respectively opened above and below the receiving groove 161, and the first bolt hole 163 communicates with the rail groove 13.

[0034] Furthermore, at least one limiting groove 164 of a limiting mechanism and at least one guide rail 165 of a guiding mechanism are radially formed on at least one side wall of the positioning tower 16, as shown in Figures 6a and 6b. Each of the inner and outer side walls of the positioning tower 16 is provided with a limiting groove 164 and a guide rail 165. The limiting groove 164 is used to engage the locking member 2 and define the radial displacement stroke of the locking member 2 within the positioning tower 16, while preventing the locking member 2 from dislodging from the opening 162 of the positioning tower 16. The guide rail 165 allows the locking member 2 to move steadily and smoothly radially within the positioning tower 16.

[0035] Furthermore, a branch rod 166 of an elastic telescopic mechanism extends radially from the middle of the bottom of the positioning tower 16, and a hinge 167 is provided at one corner. The hinge 167 includes at least one fixing piece 167a and a fastening groove 167b provided on the bottom surface of the fixing piece 167a.

[0036] The locking member 2 includes a body 21, from which a first bolt 22 extends from the bottom of one side. The first bolt 22 is inserted into the opening 162 and passes through the first bolt hole 163 in a radial displacement manner. A guide groove 211 of the guiding mechanism is provided radially between the first bolt 22 and the body 21 at each position of the guide rail 165, and a stop tenon 212 of the limiting mechanism is provided on at least one side wall of the body 21 at each position of the limiting groove 164. Please refer to Figures 5a and 6b. The opposing side walls of the positioning tower 16 are provided with a pair of limiting grooves 164 of the limiting mechanism and a pair of guide rails 165 of the guiding mechanism. The opposing side walls of the main body 21 are provided with a pair of tenons 212 fitted into the pair of limiting grooves 164 and a pair of guide grooves 211 fitted into the pair of guide rails 165. Each tenon 212 is provided with a downwardly sloping guide surface 212a to facilitate fitting into the corresponding limiting groove 164.

[0037] Furthermore, the bottom surface of the main body 21 is provided with an elastic body 23, such as a spring, disposed on the support rod 166, and a receiving hole 213 for the elastic body 23 and the support rod 166; wherein the elastic body 23 and the receiving hole 213 are also part of the elastic telescopic mechanism.

[0038] Furthermore, the main body 21 is provided with a positioning device 24 corresponding to the position of the hinge 167. The positioning device 24 includes a U-shaped swing member 241 pivotally connected to the hinge 167, for example, a pair of latching grooves 167b on the bottom surface of a pair of fixing plates 167a, and at least one guide tenon 241a extending inward from the swing member 241; and at least one track mechanism 242 with a height difference and forming a two-stage positioning is provided on the side wall of the main body 21 corresponding to the at least one guide tenon 241a, so that each guide tenon 241a is displaced and positioned in the corresponding track mechanism 242 according to a predetermined stroke. As shown in Figure 7, there is a pair of track mechanisms 242, which are symmetrically arranged on a front side wall and a rear side wall of the main body 21. Each track mechanism 242 includes a radially arranged straight groove 242a, a heart-shaped concave groove 242b connected downstream of the straight groove 242a, and an arc-shaped groove 242c connected downstream of the heart-shaped concave groove 242b and upstream of the straight groove 242a, so as to form the two-stage positioning and unidirectional travel track mechanism 242.

[0039] As shown in Figure 8, when the locking member 2 is not pressed, it is stretched by the elastic body 23, causing each of the tenons 212 to abut against the top of the limiting groove 164, while each of the guide tenons 241a of the swing member 241 is located at the starting end of the corresponding straight groove 242a, forming a first positioning configuration. At this time, the first bolt 22 is located within the receiving groove 161.

[0040] As shown in Figure 9, when the locking member 2 is pressed, it compresses the elastic body 23, causing each guide groove 211 and each stop tenon 212 to move downward along the corresponding guide rail 165 and the limiting groove 164, and causing each guide tenon 241a to move upward counterclockwise along the straight groove 242a and enter the heart-shaped concave groove 242b to form a second positioning mode. At this time, the first bolt 22 passes through the first bolt hole 163 and is located in the rail groove 13 to form a locking mode.

[0041] To unlock the locking element 2, the user only needs to press the locking element 2 again as shown in Figure 10. Since there is a first height difference section 242d at the junction of the heart-shaped concave groove 242b and the straight groove 242a, that is, the end height of the straight groove 242a is greater than the starting height of the heart-shaped concave groove 242b, each guide tenon 241a disengages from the corresponding heart-shaped concave groove 242b and is blocked by the adjacent first height difference section 242d, and can only move counterclockwise toward the arc groove 242c.

[0042] As shown in Figure 11, after the locking member 2 is released, the elastic body 23 extends, causing each guide groove 211 and each stop tenon 212 to move upward along the corresponding guide rail 165 and the limiting groove 164, and causing each guide tenon 241a to move downward in a counterclockwise direction along the arc groove 242c until each guide tenon 241a passes through a second height difference segment 242e at an intersection of the arc groove 242c and the straight groove 242a. As the locking member 2 rises and resets, each stop tenon 212 abuts against the top of the limiting groove 164, and the guide tenon 241a of the swing member 241 returns to the starting end of the straight groove 242a to form the first positioning mode; and the first bolt 22 also returns to the receiving groove 161 as shown in Figure 8 to form the unlocking mode.

[0043] Similarly, the end point height of the arc-shaped groove 242c in the second height difference section 242e is greater than the upstream section height of the straight groove 242a. Therefore, each guide tenon 241a will be blocked by the corresponding second height difference section 242e when it moves counterclockwise, and can only move counterclockwise toward the straight groove 242a.

[0044] As shown in Figures 12 and 13, the first fixed rail 11 and the second fixed rail 12 of the slide rail device 1 are fixedly mounted at intervals on a first plate 101 of a host 10, for example, on two inner sides within a pre-set plate hole 105 of the host board, to form the shape on the plate. The slide rail device 1 provides a pull-out component 20, such as a network card, for insertion and removal, and the first plate 101 has a connector 102 at the plate hole 105 and the end of the slide rail device 1. The pull-out component 20 has a second plate 201, such as a circuit board, and a pair of sliding rails 202 extending opposite each other on both sides, and each sliding rail 202 has a locking hole 203; a connecting plug 204 is provided on the inner side of the second plate 201 corresponding to the position of the connector 102.

[0045] Please refer to Figures 8, 14, and 15. The extraction component 20 is inserted into the host 10 as follows: the user inserts the pair of sliding rails 202 of the extraction component 20 into the opposing grooves 13 of the first fixed rail 11 and the second fixed rail 12, causing each sliding rail 202 to slide inward along the corresponding groove 13 until the connector plug 204 is inserted into the connector 102 (shown in Figure 14) to form an electrical connection. The locking hole 203 of the extraction component 20 is located below the first bolt hole 163 (shown in Figure 15), and the first bolt 22 is housed in the receiving groove 161, with the locking member 2 in an unpressed state. At this time, as shown in FIG8, each of the tenons 212 of the locking member 2 abuts against the top of the limiting groove 164, and each of the guide tenons 241a of the swing member 241 is located at the starting end of the corresponding straight groove 242a, so as to form the first positioning mode of unlocking.

[0046] Please refer to Figures 9, 16, and 17. The method by which the pull-out piece 20 is locked to the host 10 is as follows: the user only needs to press the locking piece 2, causing the elastic body 23 to store energy due to compression. Each guide groove 211 and each stop tenon 212 moves downward along the corresponding guide rail 165 and the limiting groove 164, causing each guide tenon 241a to move upward counterclockwise along the straight groove 242a and enter the heart-shaped concave groove 242b, thus forming the second positioning configuration. At this time, the first bolt 22 passes through the first bolt hole 163 and is inserted into the locking hole 203 in the rail groove 13, thus locking the pull-out piece 20 and preventing it from detaching from the host 10 due to vibration.

[0047] To unlock the extraction piece 20 and separate it from the host 10, press and release the locking piece 2 again as shown in Figures 10 and 11. This causes each guide tenon 241a to disengage from its corresponding heart-shaped groove 242b, and each guide groove 211 and each stop tenon 212 to move upward along their corresponding guide rails 165 and limiting grooves 164. This also causes each guide tenon 241a to move downward counterclockwise along the arc-shaped groove 242c. Until each guide tenon 241a passes through the arc-shaped groove 242c and enters the straight groove 242a, simultaneously, as the locking member 2 rises and resets, each stop tenon 212 abuts against the top of the limiting groove 164, and the guide tenon 241a of the swing member 241 returns to the starting end of the straight groove 242a, forming the first unlocked positioning state, and the first bolt 22 also returns to the receiving groove 161 as shown in FIG8. At this time, the extraction member 20 can be extracted from the slide rail device 1 of the main unit 10.

[0048] As shown in Figure 18, a second embodiment of the sliding auxiliary connection component is disclosed. In this second embodiment, the same reference numerals (symbols) are used to indicate the same components as in the first embodiment. Since the second embodiment shares many common components with the first embodiment, only the differences between the two will be described in detail below.

[0049] The second embodiment of the sliding auxiliary connection assembly is an insulator integrally molded from plastic injection molding, which includes a slide rail device 1 and a locking member 2. The slide rail device 1 includes a centrally located first fixed rail 11 and a pair of second fixed rails 12 spaced apart on both sides of the first fixed rail 11. Two pairs of rail grooves 13 are axially formed on both sides of the first fixed rail 11 and the opposite side of the pair of second fixed rails 12. Furthermore, each of the first fixed rail 11 and the second fixed rail 12 (not shown) has at least one positioning tenon 132 protruding from its bottom surface to facilitate insertion into a corresponding positioning hole 108 provided in a first plate 101 of a main unit 10 (see Figure 12).

[0050] Each of the outer surfaces of the second fixed rail 12 has a radially protruding side wing 14 at its bottom. Each side wing 14 includes at least one locking hole 141, and each locking hole 141 is for a conventional locking component, such as a screw, to pass through and be screwed into a pre-set through hole in the first plate 101. The at least one locking hole 141 is selectively located at one of a plurality of radially extending protrusions 142 of the side wing 14. As shown in FIG18, there are two locking holes 141, each located at one end of the protrusion 142. In addition to the aforementioned positioning tenon 132, the bottom surface of the first fixed rail 11 is provided with at least one bottom connection hole 133 at intervals.

[0051] The top surface of the first fixed rail 11 is provided with a protruding positioning tower 16 for mounting the locking member 2. The positioning tower 16 has a receiving groove 161. An opening 162 and a first bolt hole 163 and a second bolt hole 163' are opened opposite each other above and below the receiving groove 161, and the bolt holes 163 and 163' are each connected to a corresponding rail groove 13.

[0052] At least one limiting groove 164 of a limiting mechanism is radially formed on at least one side wall of the positioning tower 16. The two side walls of the positioning tower 16 are provided with a first guide groove 168 and a second guide groove 168' of a guiding mechanism, as shown in Figures 19a to 19d. The inner and outer side walls of the positioning tower 16 each have two limiting grooves 164. The first guide groove 168 communicates with the first bolt hole 163, and the second guide groove 168' communicates with the second bolt hole 163'. These limiting grooves 164 are used to engage the locking member 2 and define the radial displacement stroke of the locking member 2, while preventing the locking member 2 from dislodging from the opening 162 of the positioning tower 16. The first guide groove 168 and the second guide groove 168' allow the locking member 2 to move steadily and smoothly radially within the positioning tower 16.

[0053] Similarly, a branch of an elastic telescopic mechanism extends radially from the bottom middle section of the positioning tower 16 (it is concealed within the positioning tower 16 due to the projection angle), and a hinge 167 is provided at one corner (shown in Figure 19d). Similarly, the hinge 167 also includes at least one fixing piece 167a and a fastening groove 167b provided on the bottom surface of the fixing piece 167a, as in the aforementioned embodiment.

[0054] The locking member 2 includes a body 21, from which a first locking bolt 22 and a second locking bolt 22' extend from each of its two side walls, such as the inner and outer side walls. The first locking bolt 22 is inserted into the opening 162 and fitted into the first guide groove 168 for radial displacement within the first bolt hole 163, while the second locking bolt 22' is also inserted into the opening 162 and fitted into the second guide groove 168' for radial displacement within the second bolt hole 163'. Furthermore, a stop tenon 212 of the limiting mechanism is provided on each of the two side walls of the body 21 corresponding to the position of each limiting groove 164. Please refer to Figures 19a to 19d. The two opposing side walls of the positioning tower 16 are respectively provided with a pair of limiting grooves 164 of the limiting mechanism and a first guide groove 168 and a second guide groove 168' of the guiding mechanism, which are staggered. The two opposing side walls of the body 21 are respectively provided with a pair of tenons 212 fitted into the pair of limiting grooves 164, and a pair of locking bolts 22, 22' fitted into the first guide groove 168 and the second guide groove 168', respectively. Each tenon 212 is provided with a downwardly sloping guiding surface 212a to facilitate fitting into the corresponding limiting groove 164.

[0055] Furthermore, the bottom surface of the main body 21 is provided with an elastic body 23, such as a spring, on the support rod, and a receiving hole 213 for the elastic body 23 and the support rod; wherein the elastic body 23 and the receiving hole 213 are also part of the elastic telescopic mechanism.

[0056] Furthermore, the main body 21 is provided with a positioning device 24 corresponding to the position of the hinge member 167. The positioning device 24 includes a U-shaped swing member 241 pivotally connected to the hinge member 167, for example, in a pair of latching grooves 167b on the bottom surface of a pair of fixing plates 167a, and at least one free end of the swing member 241 extends inwardly with a guide tenon 241a; and at least one track mechanism 242 provided on the corresponding side wall of the main body 21. As shown in Figures 19a to 19d, there is a pair of track mechanisms 242, which are symmetrically arranged on a front side wall and a rear side wall of the main body 21. The technical content of each track mechanism 242 is exactly the same as that of the two-stage positioning and unidirectional travel track mechanism shown in the previous embodiment, and will not be described in detail here.

[0057] As shown in Figure 20, the first fixed rail 11 and the two second fixed rails 12 of the slide rail device 1 are fixedly mounted at intervals on a first plate 101 of a host 10, such as the host board, to form a plate-like structure. The slide rail device 1 is used for inserting and removing a first pull-out component 20a and a second pull-out component 20b of different specifications, such as a network card. The first plate 101 is provided with a first connector 102a and a second connector 102b (indicated by dashed lines) at the end of the slide rail device 1. The first extraction member 20a and the second extraction member 20b each have a second plate 201, such as a circuit board, and each of the second plate 201 has a pair of sliding rails 202 extending from both sides. The first extraction member 20a has a first locking hole (not shown due to the projection angle) for each of the sliding rails 202, and the second extraction member 20b has a second locking hole (not shown due to the projection angle). The inner side of the second plate 201 is provided with a first connector plug 204a and a second connector plug 204b respectively corresponding to the positions of the first connector 102a and the second connector 102b.

[0058] The manner in which the first pull-out member 20a and the second pull-out member 20b are inserted into the sliding auxiliary connection assembly of the main unit 10 is described in Figures 13 and 14 and related descriptions, and will not be repeated here. After the first pull-out member 20a and the second pull-out member 20b are both inserted into the sliding auxiliary connection assembly and positioned, the user can press the locking member 2, and the at least one guide tenon 241a of the swing member 241 forms the second positioning mode along the track mechanism 242 provided on the corresponding side wall of the main body 21, so that the first locking bolt 22 passes through the first bolt hole 163 and is inserted into the first locking hole in the track groove 13, and the second locking bolt 22' passes through the second bolt hole 163' and is inserted into the second locking hole in the track groove 13, so as to form a synchronous locking mode for the first pull-out member 20a and the second pull-out member 20b.

[0059] As shown in Figure 21, a third embodiment of the sliding auxiliary connection assembly is disclosed. Compared with the second embodiment, the same reference numerals (symbols) are used to indicate the same components in the third embodiment. Since the second embodiment and the third embodiment share many common components, only the differences between the two are described in detail below.

[0060] The third embodiment of the sliding auxiliary connection assembly is an insulator integrally molded from plastic injection molding, which includes a slide rail device 1 and a locking member 2. The slide rail device 1 includes a centrally located first fixed rail 11 and a pair of second fixed rails 12 located on both sides of the first fixed rail 11. The technical difference between the third embodiment and the second embodiment is only that, as shown in Figures 22a to 22d, the inner side wall and an outer side wall of the positioning tower 16 are each provided with a limiting groove 164 and a first guide groove 168 communicating with a first bolt hole 163 and a second guide groove 168' communicating with a second bolt hole 163', and the first guide groove 168 and the second guide groove 168' are arranged in an opposing configuration; and the two side walls of the body 21 of the locking member 2, for example, the inner and outer side walls, each extend a first locking bolt 22 and a second locking bolt 22' in an opposing and symmetrical configuration. The first bolt 22 passes through the opening 162 and is fitted into the first guide groove 168 so as to move radially within the first bolt hole 163, while the second bolt 22' passes through the opening 162 and is fitted into the second guide groove 168' so as to move radially within the second bolt hole 163'.

[0061] The advantage of the symmetrical arrangement of the first bolt 22 and the second bolt 22' of the locking member 2 is that it can be applied to a first extraction member 20a and a second extraction member 20b of the same specification.

[0062] As shown in Figure 23, the first pull-out component 20a and the second pull-out component 20b of the same specifications are inserted into the sliding auxiliary connection assembly of the main unit 10. Please refer to Figures 13 and 14 and related descriptions, which will not be repeated here. After the first pull-out component 20a and the second pull-out component 20b are both inserted into the sliding auxiliary connection assembly and positioned, the user can press the locking component 2, and the at least one guide tenon 241a of the swing component 241 forms the second positioning mode along the track mechanism 242 provided on the corresponding side wall of the main body 21. The first locking bolt 22 passes through the first bolt hole 163 and is inserted into the first locking hole in the track groove 13, and the second locking bolt 22' passes through the second bolt hole 163' and is inserted into the second locking hole in the track groove 13, so as to form a synchronous locking mode for the first pull-out component 20a and the second pull-out component 20b.

[0063] Therefore, the benefit gained through the implementation of this invention lies in the fact that the first fixed rail and the at least one second fixed rail of the sliding auxiliary connection assembly can be formed on the first plate in different forms, and a two-stage locking member is provided at the locking hole position corresponding to the second plate on the first fixed rail, which allows for manual locking and unlocking of the locking hole. This enables the pull-out component, such as a network card, containing the second plate (e.g., a circuit board), to lock and position a host (e.g., a server) containing the first plate (e.g., a motherboard) during the sliding of the slide rail device, preventing the connector of the first plate from disengaging from the connection plug of the second plate, thus ensuring the stability of the electrical connection. Furthermore, the locking and unlocking of the sliding auxiliary connection assembly can be operated with only one hand, allowing the other hand to hold the pull-out component for pulling and separating, making it a remarkable invention unprecedented in its class.

[0064] The present invention discloses one of the preferred embodiments. Any partial changes or modifications that are derived from the technical concept of this invention and can be easily deduced by a person skilled in the art are not outside the scope of the patent rights of this invention.
