Description

Technical Field

[0001] The utility model relates to a clamping structure, in particular to a clamping structure for carrying and electrically connecting plates with different lengths and sizes. Background Art

[0002] It is known that at least one slot-type connector is electrically connected to the carrier (main board, back board or expansion board) inside the current electronic device on the market. When the electronic device needs to expand its functions, plates with different functions (such as memory cards, solid-state drives or other auxiliary interface cards) will be plugged into these connectors.

[0003] After the plate is electrically connected to the carrier, in order to stably install the plate on the carrier, at least one fixing hole is provided on the carrier. After the screw is locked in the fixing hole, the head of the screw presses on the notch of the pressure-receiving part of the plate, so that the plate can be stably installed on the carrier.

[0004] Since the plates with different functions are also designed with different lengths. When the carrier is to use these numerous plates and the lengths of the plates themselves are different, it is necessary to provide a plurality of fixing holes on the carrier to accommodate the assembly of different plate sizes. In this way, when the number of the fixing holes is large, it will be difficult to design the circuit traces on the surface of the carrier and increase the difficulty of manufacturing the carrier.

[0005] Therefore, how to improve the traditional deficiencies and only design one fixing hole on the carrier to assemble plates with different sizes is the problem to be solved by the utility model. Summary of the Invention

[0006] Therefore, the main purpose of the utility model is to solve the above problems. The utility model provides a fixing element. When there is a distance gap between the pressure-receiving part of the plate and the fixing hole after the plate is installed on the carrier and the notch of the pressure-receiving part cannot correspond to the upper part of the fixing hole on the carrier, the fixing element can be used for assembly, so that only one fixing hole needs to be designed on the carrier.

The fixing element includes a plate body and a locking member. One end of the plate body has a through hole corresponding to the fixing hole, and the other end of the plate body corresponding to the through hole has a pressing piece. Wherein, after the first plate is mounted on the carrier, there is a distance gap between the notch and the fixing hole, so that when the notch cannot correspond to the upper part of the fixing hole, the fixing element is placed on the carrier, so that the through hole on the plate body corresponds to the fixing hole, and after the locking member passes through the through hole and is fixed to the fixing hole, the pressing piece presses on the pressed portion.

[0034] Regarding the technical content and detailed description of the present utility model, it is described in detail below with reference to the accompanying drawings:

[0035] Please refer to Figure 1 and 2 , which are the exploded three-dimensional schematic diagram of the carrier and the first plate of the first embodiment of the present utility model and Figure 1 the assembled three-dimensional schematic diagram of the carrier and the first plate. As shown in the figure: The plate clamping structure of the present utility model includes: a carrier 10, a first plate 20 and a fixing element 30. Among them, when the first plate 20 is assembled to the carrier 10, the fixing element 30 presses on the first plate 20, so that the first plate 20 is stably carried on the carrier 10.

[0036] The carrier 10 is used to carry the first plate 20, and a connector 101 is electrically connected to one end thereof. The connector 101 is a socket-type connector. The other end of the carrier 10 corresponding to the connector 101 has a fixing hole 102, and a threaded surface 103 is provided in the fixing hole for a locking member to be locked. In this figure, the carrier 10 is the main board (circuit board), back board or expansion board of an electronic device.

[0037] The first plate 20 is mounted and carried on the carrier 10. One end of the first plate 20 has a conductive pin 201 of a gold finger, and the conductive pin 201 is inserted into the connector 101, so that the first plate 20 is located on the carrier 10. The other end of the first plate 20 corresponding to the conductive pin 201 has a pressed portion 202, and a semicircular notch 203 is provided on the pressed portion 202 for the fixing element 30 to be fixed. In this figure, the first plate 20 is an expansion card, and the expansion card is a memory card or a solid state drive (SSD).

[0038] The fixing element 30 is made of a metal material and includes a plate body 301 and a locking member 302. One end of the plate body 301 has a through hole 3011 corresponding to the fixing hole 102, and a pressing piece 3012 is provided at the other end of the plate body 301 corresponding to the through hole 3011. The pressing piece 3012 is used to press on the notch 203 of the pressed portion 202 of the first plate 20. Then, the locking member 302 is fixed to the fixing hole 102 through the through hole 3011. In this figure, the locking member 302 is a screw.

[0039] Please refer to Figure 3 , which is Figure 2 the side cross-sectional schematic diagram; at the same time, please refer to Figure 1 and 2As shown in the figure: When the first plate 20 of the present utility model is installed on the carrier 10, first insert the conductive pin 201 of the first plate 20 into the connector 101 of the carrier 10 so that the first plate 20 is located on the carrier 10. At this time, after the first plate 20 is installed on the carrier 10, there is a certain distance gap between the notch 203 of the pressed portion 202 of the first plate 20 and the fixing hole 102. When the notch 203 cannot be aligned above the fixing hole 102, the fixing element 30 can be placed on the carrier 10 so that the through hole 3011 on the plate body 301 corresponds to the fixing hole 102. After the locking member 302 passes through the through hole 3011 and is fixed to the fixing hole 102, the pressing piece 3012 of the fixing element 30 presses on the notch 203 of the pressed portion 202, so that the first plate 20 can be stably installed on the carrier 10.

[0040] Through the design of the fixing element 30, when the length of the first plate 20 itself is not long enough, it can still be installed on the carrier 10 with the assistance of the fixing element 30.

[0041] Please refer to Figure 4 、 5 , which are the exploded perspective view of the carrier and the second plate of the second embodiment of the present utility model and Figure 4 the assembled perspective view of the carrier and the second plate. As shown in the figure: This embodiment is substantially the same as the first embodiment, the difference being that the length of the second plate 40 of the second embodiment itself is longer than the length of the first plate 20 itself.

[0042] Similarly, one end of the second plate 40 has a conductive pin 401 with a gold finger, and the conductive pin 401 is also inserted into the connector 101 so that the second plate 40 is located on the carrier 10. The other end of the second plate 40 corresponding to the conductive pin 401 has a pressed portion 402, and a semicircular notch 403 is provided on the pressed portion 402 for fixing the locking member 302. In this figure, the second plate 40 is also an expansion card, and the expansion card is a memory card or a solid state drive (SSD).

[0043] When the second board 40 is installed on the carrier 10, first insert the conductive pin 401 of the second board 40 into the connector 101 of the carrier 10 so that the first board 20 is located on the carrier 10. Since the length of the second board 40 is longer than that of the first board 20, after the second board 40 is installed on the carrier 10, the notch 403 of the second board 40 is directly aligned with the fixing hole 102 of the carrier 10. Then, after passing the locking member 302 through the notch 403 and locking it to the fixing hole 102, the head 3021 of the locking member 302 can press on the notch 403 of the pressed portion 402 of the second board 40. At this time, because the length of the second board 40 is long enough, the fixing element 30 does not need to be used to assist in the fixed installation.

[0044] The above description is only the preferred embodiment of the present invention and is not intended to limit the scope of patent protection of the present invention. Therefore, all equivalent changes made by using the content of the specification or drawings of the present invention are equally included in the scope of the rights of the present invention, and this is hereby stated.
