In one embodiment, the outer circumferential surface of the cylinder is axially provided with a plurality of positioning grooves; the thickness of the rotating handle is greater than the thickness of the collar and the blocking wing, and the inner side of the rotating handle is adjacent to the blocking block. At least one positioning tenon is protruding axially from the surface, and each positioning tenon can mesh with a corresponding positioning groove, so that the rotating part cannot rotate arbitrarily on the cylinder.

In one embodiment, the spacer column further includes a joint member, the joint member is engaged in the joint hole, and a head of the joint member is adjacent to the collar.

In one embodiment, the spacer column further includes a joint member with a head. After an elastic member is passed through the joint member, it is then connected in the joint hole so that the elastic member is between the collar and the between the heads, and can apply pressure on the collar to make the second plate and the fixing member closely fit to form electrical contact.

Please refer to Figures 2 to 8. Basically, in this case, the spacer column with conductive function includes a fixed part 1 and a rotating part 2. The fixing member 1 is made of conductive materials, such as metal elements, alloys (copper alloys, aluminum alloys, etc.), composite metals or composite polymer conductive materials, such as conductive plastics. The rotating member 2 is preferably made of an insulating material, such as plastic, and is integrally injection molded.

The fixing member 1 includes a geometric shape, such as a multi-step circular cylinder 11. The bottom surface of the cylinder 11 extends axially to be combined with a first plate 5 (shown in Figure 7), such as a circuit board. The coupling post 12, in one embodiment, is a rod body with male threads, protruding rings or annular grooves. The top surface of the column 11 has a support surface 111 for placing a second plate 6, such as an M.2 solid state drive, a Wi-Fi wireless network card, a 3G network card or a circuit board. The support surface 111 extends axially. An axis column 13 is provided, and a coupling hole 131 is axially opened in the shaft column 13. In one embodiment, the coupling hole 131 is a hole groove with a female thread. Furthermore, a step 132 is provided at the intersection between the shaft column 13 and the supporting surface 111 . The shaft column 13 and the step 132 are respectively used for sleeve connection and contact support of the rotating member 2 .

In addition, a plurality of positioning grooves 112 are provided axially around the outer circumferential surface of the cylinder 11, and the positioning grooves 112 are used for engaging and positioning the rotating member 2 during rotation.

The rotating member 2 includes a collar 21 that is sleeved on the shaft column 13 and straddles the step 132 . The collar 21 radially extends an arc-shaped baffle 211 . A free end of the blocking wing 211 is provided with a guide slope 212, and a stopper 213 (shown in Figure 3) that stops rotating when it touches the second plate 6 is protruding from the other end of the bottom surface of the blocking wing 211. The guide slope 212 is used to guide the baffle 211 to rotate and move along the second plate 6 (shown in Figure 10), so as to lock the second plate 6 so as not to separate from the spacer column; and the baffle 211 and the supporting surface 111 can clamp the second plate 6 to ensure that the second plate The material 6 can form a close fitting relationship with the conductive pillar 11 . When the stopper 213 touches the second plate 6 during rotation, it cannot continue to rotate.

Furthermore, a rotating handle 22 for the user's fingers to hold is radially protruded from the outer circumferential surface of the blocking wing 211. When the rotating handle 22 is rotated, the blocking wing 211 and the collar 21 can rotate synchronously.

What's more, the thickness of the rotating handle 22 is greater than the thickness of the collar 21 and the blocking wing 211. Therefore, at least one positioning tenon 222 is axially protruded from the inner side of the rotating handle 22 and an adjacent surface 221 with the stopper 213. Each positioning tenon 222 can engage with a corresponding positioning groove 112 so that the rotating member 2 cannot rotate arbitrarily on the column 11 .

In order to further prevent the rotating member 2 from being detached from the shaft column 13, the spacer column further includes a coupling member 3, such as a bolt, and the coupling member 3 is connected, for example, screwed in the coupling hole 131, so that the coupling member 3 A head 31 of 3 is adjacent to the collar 21 to limit the axial movement of the rotating member 2 .

In addition, an elastic member 4 is added between the collar 21 and the head 31 so that the elastic member 4 pressurizes the collar 21 so that the second plate 6 can closely fit the fixing member 1 .

In another embodiment, in order to produce a pressurizing effect on the second plate 6 , an elastic member 4 , such as a spring, is inserted through the joint member 3 having a head 31 and then connected in the joint hole 131 , so that the elastic member 4 is interposed between the collar 21 and the head 31 so that the reaction force of the elastic member 4 can be used to press the collar 21 of the rotating member 2 so that the second plate 6 can It is in close contact with the fixing member 1 to form electrical contact.

As shown in FIG. 4 , it shows a perspective view of the fixing part 1 , the rotating part 2 , the elastic part 4 and the joint part 3 after they are assembled according to the above description and have not yet been operated. Among them, FIG. 5 shows a cross-sectional view taken along line A-A in FIG. 4 , from which the relative positional relationship of all components after assembly can be clearly seen. FIG. 6 shows a cross-sectional view taken along line B-B in FIG. 4 . It can be clearly seen from the figure that the positioning tenon 222 is engaged with a corresponding positioning groove 112 .

Please refer to Figures 7 to 11. If the spacer column is to be used as the first plate material 5, such as a circuit board and the second plate material 6, for example, it can be selected from the group consisting of M.2 solid state drives, Wi-Fi wireless network cards, and 3G network cards. Or the space between circuit boards, wherein the first board 5 includes a plurality of positioning posts 51 also made of conductive material, such as copper alloy and arranged in a linear manner, and a connector 52 .

When assembling, the user first selects a positioning post 51 with a matching length according to the length of the second plate 6 for the joint post 12 of the fixing member 1 , and then combines the joint post 12 with, for example, screwing to the positioning post 51 In a preset column hole 511 (shown in FIGS. 7 and 8 ), the spacer column is connected to the selected positioning column 51 on the first plate 5 .

Then, a contact portion 61 at one end of the second plate 6 is inserted into the connector 52 on the first plate 5; and a positioning recessed hole 62 at the other end is moved downward and placed on the supporting surface 111 (shown in 9 and 10), so that the positioning recessed hole 62 is sleeved on the shaft column 13. At this time, the user rotates the rotating handle 22 in the counterclockwise direction, so that the collar 21 takes the shaft 13 as the axis and rotates synchronously with the blocking wing 211 . When the guide slope 212 touches an end edge of the second plate 6, the blocking wing 211 will be prompted to move along the end edge until the stopper 213 touches the end edge, and immediately stops moving, and the positioning tenon 222 It is engaged in a positioning groove 112 to form a positioning outside, and the blocking wing 211 just covers the positioning recessed hole 62 to form a locking state (shown in FIG. 11 ), because the fixing member 1 is fixed to the first On the board 5 , the second board 6 has a stable positioning effect, which prevents shaking and ensures the electrical connection between the second board 6 and the connector 52 .

As shown in Figure 12, it shows a cross-sectional view taken along the line C-C of Figure 11 after the spacer column, the first plate 5 and the second plate 6 are assembled. It can be clearly observed from the figure that the baffle wing 211 and the supporting surface 111 jointly clamp the second plate 6, and through the axial pressure generated by the joint member 3 and the elastic member 4, a conductive piece 621 (shown in the figure) around the positioning recessed hole 62 9) It can closely fit the fixing member 1 to form electrical contact, so that the first plate 5, the spacer column and the second plate 6 together form a ground loop to reduce the generation of electromagnetic interference.

Therefore, when the rotating handle 22 is rotated, the collar 21 and the blocking wing 211 rotate synchronously, and the positioning tenon 222 is used to engage in a positioning groove 112, and whether the blocking wing 211 covers the second plate 6 The positioning recessed hole 62 serves as a basis for locking or unlocking the second plate 6 . If it is in the locked state, at least a part of the blocking wing 211 and the supporting surface 111 jointly enclose the positioning groove 112 of the second plate 6, so that the second plate 6 has a stable positioning effect without shaking. condition.

Therefore, through the implementation of this case, the effect gained is that the fixing member made of conductive material allows the radio wave noise generated when the electronic components on the second plate operate to be conducted to the second plate through the fixing member with conductive function. The grounding circuit of the first plate thereby achieves the effect of eliminating electromagnetic interference. In addition, the joints and elastic parts further provided on the spacer column can pressurize the rotating part, so that the second plate can closely fit the fixed part, avoid shaking, and ensure the stability of the second plate. The electrical connections are one of the best of its kind never seen before.
