Description

Technical Field

[0001] The utility model relates to a spacer post, and particularly to a spacer post with a conductive function. Background Art

[0002] In computers or electronic products, in order to separate a board, such as a printed circuit board, from another board, such as the motherboard of a housing or another printed circuit board, a plurality of spacer posts are usually inserted between the boards to separate the two boards from each other. This can not only provide a stable support and positioning effect for the printed circuit board, but also avoid the occurrence of short circuits caused by the superposition of the two boards.

[0003] As Figure 1 shown, a cross-sectional view of a known spacer post installed on two boards is disclosed. At both ends of a positioning member 10, a first elastic hook 101 and a second elastic hook 102 are integrally provided respectively. The first elastic hook 101 is inserted into a first board hole 501 of a first board 50, such as a metal motherboard, and the second elastic hook 102 is inserted into a second board hole 601 of a second board 60, such as a printed circuit board, so that the positioning member 10 is located between the first and second boards 50 and 60, and a distance is formed between the first board 50 and the second board 60.

[0004] However, the positioning member 10 is made of insulating plastic, so the radio wave noise generated by the second board 60 cannot be conducted to the first board 50 in a grounded manner, resulting in electromagnetic interference (abbreviated as EMI), which urgently needs to be improved. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a spacer post with a conductive function, which can be quickly installed between a first board and a second board, and the spacer post itself has a conductive function, so that although the spacer post separates the first board and the second board, the first board and the second board can still be electrically contacted through the spacer post to form a grounding circuit between the two, so as to reduce the generation of electromagnetic interference.

[0006] The secondary purpose of the utility model is to provide a spacer post with a conductive function, which is provided with an elastic member capable of generating radial energy storage and energy release between a fixing member and a rotating member to obtain the functions of manual unlocking and automatic locking, and the elastic member can further provide a spacer height function in addition to providing a conductive function.

[0011] In an embodiment, the spacer column further includes a locking member for being installed on the joint column, and the inner peripheral surface of a through hole of the locking member is correspondingly radially provided with a locking portion such as internal threads, annular grooves or protruding rings with respect to the outer peripheral surface of the joint column; after the joint column penetrates a plate hole of the first plate preset and corresponding to the cross section of the joint column, the locking portion of the locking member is connected to the joint portion of the joint column.

[0012] In one embodiment, a flange for straddling the elastic member protrudes radially between the engaging post and the shaft post. The first plate is provided with a plate hole for the engaging post to pass through and having a cross-section corresponding to that of the engaging post.

[0054] Figure 12 The sectional view of the second embodiment of the spacer column of the present utility model combined with the first plate. Detailed Description of the Invention

[0055] Please refer to Figures 2 to 8 , basically, the spacer column with conductive function of the present utility model includes a fixing member 1, an elastic member 2, a rotating member 3, and a joining member 4. Wherein the fixing member 1 and the elastic member 2 are each 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. And the rotating member 3 is preferably integrally injection molded from an insulating material, such as plastic.

[0056] The fixing member 1 includes a geometric shape, such as a multi-step circular cylinder 11, and a joining post 12 axially extending from the bottom of the cylinder 11 for joining to a first plate 6 (shown in Figure 6 ), such as a circuit board. In one embodiment, at least one positioning cut surface 121 is axially provided on a part of the outer peripheral surface of the joining post 12, and a joining portion 122 with male threads, protruding rings or annular grooves is radially provided on the remaining part of the outer peripheral surface. And a shaft post 13 is axially provided at the top of the cylinder 11, and a flange 14 for the elastic member 2 to straddle is radially protruded between the shaft post 13 and the joining post 12.

[0057] Furthermore, a first foot groove 131 is radially provided on the shaft post 13 to divide the shaft post 13 into a first support surface 132 and a second support surface 133. Wherein the first support surface 132 is used to support a second plate 7 (shown in Figure 6 ), such as an M.2 solid state drive, a Wi-Fi wireless network card, a 3G network card or a circuit board, and the second support surface 133 is used to support the rotating member 3. In addition, a column step 134 for fixing the second plate 7 and serving as the rotation angle limit of the rotating member 3 is protruded on the top surface of the first support surface 133. Further, a joining hole 135 is axially opened at the intersection position of the column step 134 and the first foot groove 131 of the shaft post 13, and the joining hole 135 is a hole groove with female threads in one embodiment. And the two ends of the column step 134 are separated by the joining hole 135 to form a first stop 134a and a second stop 134b.

[0058] The elastic member 2 is also made of a conductive material. It is a metal elastic body for radial energy storage and release, such as a torsion spring. It has a first end leg 21 sleeved in the first leg groove 131 and a second end leg 22 connected to the rotating member 3.

[0059] The rotating member 3 includes a collar 31 disposed on the column step 134. The collar 31 includes an annular hole 311 and an arc-shaped retaining wing 312 extending radially. A guiding inclined surface 313 is provided at a free end of the retaining wing 312, and a stop block 314 (shown in Figure 3 ) that stops rotating when touching the column step 134 and is disposed above the second support surface 133 protrudes from one side of the bottom surface of the collar 31. The guiding inclined surface 313 is used to guide the retaining wing 312 to rotate and move along the second plate 7 (shown in Figure 8 ) so as to lock the second plate 7 and prevent it from separating from the spacer column. The retaining wing 312 and the first support surface 132 can clamp the second plate 7 to ensure that the second plate 7 forms a close fitting relationship with the conductive column 11 and the elastic member 2. During rotation, when the stop block 314 touches the first stop 134a or the second stop 134b of the column step 134, it cannot continue to rotate. One end of the stop block 314 is provided with a first stop wall 314a that can form an abutment corresponding to the first stop 134a of the column step 134, and the other end of the stop block 314 is provided with a second stop wall 314b that can form an abutment corresponding to the second stop 134b.

[0060] Furthermore, a rotating handle 32 for the user's finger to hold protrudes radially from the outer peripheral surface of the collar 31, and a second leg groove 321 for sleeving the second end leg 22 is radially provided on the rotating handle 32. Therefore, when the rotating handle 32 is rotated, the retaining wing 312, the collar 31, and the second end leg 22 can rotate synchronously, and the elastic member 2 forms an energy storage state.

[0061] To further prevent the rotating member 3 from detaching from the shaft column 13 and the column step 134, the spacer column further includes a joining member 4, such as a bolt. The joining member 4 passes through the annular hole 311 and is connected, for example, screwed into the joining hole 135. The joining member 4 includes a connecting section 41 connected to the joining hole 135 and a sleeved section 42 sleeved in the annular hole 311, and a head portion 43 abuts against the collar 31 to limit the axial movement of the rotating member 3.

[0062] To enable the joining column 12 to be quickly combined with the first plate 6, the spacer column further includes a locking member 5 for connecting to the joining column 12, and a locking portion 511 with internal threads, annular grooves, or protruding rings is radially provided on the inner peripheral surface of a through hole 51 of the locking member 5 corresponding to the outer peripheral surface of the joining column 12.

[0063] As Figure 4 shown, it shows a three-dimensional view of the fixing member 1, the elastic member 2, the rotating member 3, and the engaging member 4 assembled according to the foregoing description and not yet operated. Among them, Figure 5 shows Figure 4 a cross-sectional view taken along line A-A. From the figure, the relative positional relationship of all components after assembly can be clearly seen. In particular, the first end foot 21 of the elastic member 2 is sleeved in the first foot groove 131 of the shaft column 13; and the second end foot 22 of the elastic member 2 is sleeved in the second foot groove 321 of the rotating handle 32, so that the elastic member 2 has the effect of radial energy storage and energy release.

[0064] Please refer to Figures 7 to 10 , which previously shows a schematic flow chart of installing the spacer column on the first plate 6, such as a circuit board, and the second plate 7, such as selected from an M.2 solid-state drive, a Wi-Fi wireless network card, a 3G network card, or a circuit board. Among them, the first plate 6 includes a plate hole 61 with a cross-section the same as that of the engaging column 12, and a connector 62.

[0065] When the user assembles, first, the user inserts the engaging column 12 of the fixing member 1 into the plate hole 61 (shown in Figure 6 ), and then screws the locking portion 511 of the locking member 5, such as an internal thread, to the engaging portion 122 of the engaging column 12, such as an external thread, so that the spacer column is combined with the plate hole 61 of the first plate 6. Since the outer peripheral surface of the engaging column 12 has at least one positioning cutting surface 121, and the plate hole 61 is provided with a matching complementary cutting surface 611 corresponding to the at least one positioning cutting surface 121, the spacer column will not rotate on the first plate 6, so that the first support surface 132 faces the connector 62.

[0066] Next, rotate the rotating handle 32 of the rotating member 3 in the clockwise direction until the first stop wall 314a of the stop block 314 stops at the first stop 134a of the column step 134, so that the elastic member 2 stores energy. Subsequently, insert a contact portion 71 at one end of the second plate 7 into the connector 62 on the first plate 6; and move the positioning concave hole 72 at the other end downward and place it on the first support surface 132 (shown in Figure 7 and Figure 9), so that the positioning concave hole 72 is sleeved on the column step 134. At this time, the user releases the rotating handle 32, and the rotating member 3 automatically rotates counterclockwise to reset by the energy release of the elastic member 2; at this time, the ring hole 311 of the collar 31 takes the socket section 42 of the engaging member 4 as the axis and rotates synchronously with the retaining wing 312. When the guiding inclined surface 313 touches one end edge of the second plate 7, it will cause the retaining wing 312 to move along the end edge until the second retaining wall 314b of the retaining block 314 stops against the second stop 134b of the column step 134 and immediately stops moving to form a positioning state, and at least a part of the retaining wing 312 just shields a partial peripheral area of the positioning concave hole 72 to form a locking state (shown in Figure 8 and Figure 10 ). Since the fixing member 1 is fixedly connected to the first plate 6 and makes the second plate 7 have a stable positioning effect, in addition to preventing shaking, it can ensure the electrical connection between the second plate 7 and the connector 62.

[0067] As Figure 11 shown, it shows a partial sectional view taken after the spacer column, the first plate 6 and the second plate 7 are assembled. It can be clearly observed from the figure that the retaining wing 312 and the first supporting surface 132 jointly clamp the second plate 7, and through the axial pressing action generated by the elastic member, a conductive layer 721 (such as a copper foil layer, shown in Figure 6 , Figure 9 and Figure 10 ) around the positioning concave hole 72 can closely fit the fixing member 1 to form electrical contact, so that the first plate 6, the spacer column and the second plate 7 together form a grounding circuit to reduce the generation of electromagnetic interference. Furthermore, as shown before, the implementation of inserting the engaging column 12 of the fixing member 1 into the plate hole 61 and screwing it to the locking portion 511 of the locking member 5 is the first embodiment of the spacer column combined with the first plate 6.

[0068] As Figure 12 shown, it shows another partial sectional view taken after the spacer column, the first plate 6 and the second plate 7 are assembled. It can be clearly observed from the figure that a contact pad 612, such as a solder layer, is provided in the peripheral area of the plate hole 61, so that after the bottom surface of the flange 14 of the spacer column is placed, and then using the surface mount technology (SMT), the implementation of fixing the spacer column on the first plate 6 is the second embodiment of the spacer column combined with the first plate 6.

[0069] Therefore, when the turning handle 32 is rotated, the collar 31 and the retaining wing 312 rotate synchronously to form an unlocking state for the second plate 7, while storing energy in the elastic member 2. Additionally, when the turning handle 32 is released, the elastic member 2 releases energy, causing the collar 31 and the retaining wing 312 to rotate synchronously in the reverse direction, and at least a portion of the retaining wing 312 shields the surrounding area of the positioning recess 72 of the second plate 7 to form a lock for the second plate 7, enabling the second plate 7 to achieve a stable positioning effect without wobbling.

[0070] Therefore, through the implementation of the present utility model, the enhanced efficacy lies in that the fixing member and the elastic member made of conductive materials enable the radio wave noise generated when the electronic components on the second plate operate to be conducted to the grounding circuit of the first plate through the fixing member with conductive function, thereby achieving the effect of eliminating electromagnetic interference. In addition, the elastic member provided by the spacer column can provide elastic support and conductive function to the second plate, enabling the second plate to closely fit the fixing member, not only preventing wobbling, but also ensuring the electrical connection of the second plate, which is an excellent structure unprecedented in similar articles.

[0071] What is disclosed in the present utility model is one of the preferred embodiments. Any partial change or modification that is easily inferred by those skilled in the art from the technical idea of the present utility model shall fall within the scope of the patent right of the present utility model.
