Description

Fixture for unlocking fasteners

The present invention relates to a jig for unlocking fasteners, and in particular to a jig for unlocking fasteners which can unlock fasteners of a connector at the same time.

Generally speaking, in the existing technology, if you want to be able to open the latch of a connector, such as the latch of a dual in-line memory module (DIMM) connector, there are two existing methods, but both have their corresponding disadvantages. The first method is to use the user's fingers to open the latches of the DIMM connector one by one, and the corresponding disadvantages are: (A) it takes a long time to operate; and (B) when the user's fingers are opened for a long time, they are likely to feel pain, which is actually quite inconvenient. In addition, the second method is to use a special jig to disengage the lock of the DIMM connector. For example, a one-piece jig is used, and a bend is provided at the end of the jig to hook the lock of the DIMM connector. The user's finger is then used to disengage the other end of the jig to disengage the lock of the DIMM connector. The corresponding disadvantages are: (A) since there is no stop design, the user needs to rely on his or her own feeling to avoid over-operation and damage to the lock of the DIMM connector; (B) the design of the lock of the connector is not applicable to all types of connectors, and a customized design is required to overcome this problem; and (C) If there are other tall electronic components next to the DIMM connector, this method may not be used because there is a possibility of damaging other electronic components.

As mentioned above, in order to effectively solve the inconvenience of the above two methods to unlock the lock fastener of the connector, it is urgently needed to provide a design to solve the above problems.

In view of the inconvenience caused by the prior art, the present invention adopts a necessary technical means to solve the problems of the prior art, which is to provide a jig for disengaging a plurality of fasteners of a connector, and the fasteners are respectively arranged on the first side and the second side of the connector. The jig for disengaging the fasteners comprises: a first plate body and a second plate body, a hollow cavity and a pair of extension cavities are formed between the first plate body and the second plate body, and the pair of extension cavities are respectively connected to a first side and a second side of the hollow cavity; a pressing portion is arranged in the hollow cavity ; a pair of extension arms, respectively disposed in the pair of extension cavities and respectively connected to the pressing portions; and a pair of levers, respectively partially disposed in the pair of extension cavities and respectively combined with the first plate body and the second plate body, the pair of levers being slidingly connected to the pair of extension arms, and the pair of levers corresponding to the first side and the second side of the connector, respectively, for disengaging a plurality of fasteners of the connector; wherein, when the pressing portion is in a first position, the pressing portion links the pair of extension arms to respectively drive the pair of levers to rotate to a disengaging position, for disengaging the fasteners from a locking position to an opening position.

An auxiliary technical means derived from the above necessary technical means further includes a supporting plate and a pair of supporting structures. The supporting plate is combined with the first plate body and the second plate body, and the pair of supporting structures respectively protrude from one side of the supporting plate corresponding to the connector and are respectively adjacent to multiple locking fasteners of the connector to maintain the position of the lever.

In an auxiliary technical means derived from the above necessary technical means, each of the pair of levers has a rotating shaft, whereby the pair of levers are pivotally connected to the first plate and the second plate.

As described above, since the jig for releasing the lock of the present invention is to press down the pressing portion disposed on the top by the user, the claw element below it will rotate left and right at the same time after pressing, so as to release the lock of the connector. Therefore, the present invention can effectively achieve the purpose of releasing the lock of the connector at the same time through this design.

The specific embodiments of the present invention will be further described by the following embodiments and drawings.

Please refer to the contents shown in Figure 1, Figure 2A to Figure 2B, and Figure 3A to Figure 3B. Figure 1 is a three-dimensional diagram of the jig for unfastening the fastener provided in the preferred embodiment of the present invention; Figure 2A is a schematic diagram of the action of the jig for unfastening the fastener provided in the preferred embodiment of the present invention before being pressed; Figure 2B is a schematic diagram of the action of the jig for unfastening the fastener provided in the preferred embodiment of the present invention after being pressed; Figure 3A is a cross-sectional view of Figure 2A; and Figure 3B is a cross-sectional view of Figure 2B.

As shown in the first figure, the present invention provides a jig 1 for unlocking a fastener, which comprises: a first plate 11 and a second plate 12, a pressing portion 18, a pair of extension arms 14 and a pair of unlocking rods 15.

Among them, a hollow cavity 120 and a pair of extended cavities 121 are formed between the first plate body 11 and the second plate body 12, and the pair of extended cavities 121 are respectively connected to a first side and a second side of the hollow cavity 120, that is, on the left and right sides as shown in the first figure, the fixture 1 for disengaging the fastener is a mirror-symmetrical structure, and its left and right sides have the same structure and connection method, and the similarities will not be repeated below.

The pressing portion 18 is disposed in the aforementioned hollow cavity 120. After being pressed by the user, the pressing portion 18 is in a first position (as shown in the second B figure and the third B figure), and before being pressed by the user and after being released, the pressing portion 18 is in a second position (as shown in the second A figure and the third A figure).

In addition, a pair of extension arms 14 are respectively disposed in one of the pair of extension cavities 121 and are respectively connected to the pressing portion 18.

In addition, a pair of levers 15 are respectively partially disposed in the aforementioned pair of extension cavities 121, and are respectively combined with the first plate 11 and the second plate 12, and are respectively slidably connected to the aforementioned pair of extension arms 14, and the manner of the slidably connected is described below. The levers 15 are used to disengage multiple fasteners 21 of a connector 2 (only one on each side is marked in the second A figure), and the aforementioned multiple fasteners 21 are respectively disposed on a first side and a second side of the connector 2, and the aforementioned pair of levers 15 correspond to the first side and the second side of the connector 2, respectively. Here, the connector 2 is a mirror-symmetrical structure, and its first side and second side have the same structure and connection method, that is, the left and right sides in the second FIG. A and the second FIG. B, and the similarities will not be repeated below.

When the pressing portion 18 is in the first position after being pressed by the user, the pressing portion 18 links the extension arm 14 to drive the lever 15 to rotate to a disengagement position (as shown in the second B figure and the third B figure), so as to simultaneously disengage the multiple locking elements 21 of the connector 2 from a locking position (as shown in the second A figure) to an opening position (as shown in the second B figure). The two levers 15 rotate in opposite directions, that is, the multiple locking elements 21 located on the first side and the second side of the connector 2 can be disengaged in different directions. Thus, when the user presses the protruding pressing portion 18 disposed on the top, the two claw elements 153 located below the two levers 15 will rotate left and right at the same time to release the multiple fasteners 21 of the connector 2, such as the fasteners of the DIMM connector in the server and the corresponding structures thereof.

The present invention further comprises a supporting plate 16 and a pair of supporting structures 17. The supporting plate 16 is combined with the first plate 11 and the second plate 12, and the supporting structure 17 protrudes from a side of the supporting plate 16 corresponding to the connector 2, and the pair of supporting structures 17 are respectively adjacent to a plurality of fasteners 21 of the connector 2, i.e., the left and right sides in the second A and second B figures, to maintain the position of the lever 15. The supporting structure 17 is against the plane of the connector 2 to maintain the height between the overall fixture 1 for unlocking the fasteners and the connector 2.

In addition, please refer to FIG. 3A and FIG. 3B, the present invention is further provided with a rebound structure 13, which is disposed in the aforementioned hollow cavity 120 and connected to the pressing portion 18, and is used to rebound the pressing portion 18 located at the first position after being pressed by the user to the second position before being pressed. The aforementioned rebound structure 13 includes a stop plate 131 and an elastic element 132, the stop plate 131 is combined with the first plate body 11 and the second plate body 12, and the elastic element 132 connects the stop plate 131 and the pressing portion 18, and is used to rebound the pressing portion 18 to the second position. When the pressing portion 18 rebounds to the second position, the pressing portion 18 links the extension arm 14 to drive the lever 15 to rotate in the opposite direction to a recovery position (as shown in the second A figure and the third A figure), returning to the state before being pressed.

The detailed design of the linkage structure of the lever 15 of the present invention is as follows: the lever 15 has a rotating shaft 151, whereby the lever 15 is pivotally connected to the first plate 11 and the second plate 12. The extension arm 14 has a slide rail 141, and one end of the lever 15 has a boss 152, and the boss 152 can slide in the slide rail 141. In addition, the other end of the lever 15 opposite to the rotating shaft 151 has a claw element 153 for disengaging the multiple locks 21 of the connector 2.

Thus, when the user presses the protruding pressing portion 18 disposed at the top, the extension arm 14 moves downward, and at this time, the slide rail 141 drives the protruding column 152 to slide and move. Since the lever 15 is provided with a fixed shaft 151, when the slide rail 141 moves downward, the lever 15 is pushed outward with the shaft 151 as a fulcrum, so as to release the lock 21 of the connector 2. When the user releases the pressing portion 18, the elastic element 132 will support the pressing portion 18, drive the extension arm 14 to move upward, and then the lever 15 can be restored to the original position through the reverse operation of the aforementioned structure.

In addition, the claw element 153 has a plurality of claws 1531 (only one is shown in the figure), that is, the number of the claw elements 153 can be designed to correspond to the number of the plurality of fasteners 21 of the connector 2, so that the claws 1531 can smoothly release the plurality of fasteners 21 at the same time.

The utility of the fastener disengaging jig 1 of the present invention is as follows: (A) this design can be used to further produce a design for disengaging fasteners that is applicable to other types of connectors; (B) in one operation, that is, when the user presses the pressing portion 18, multiple fasteners 21 located on both sides of the connector 2 can be disengaged at the same time; and (C) the operation of the present invention is convenient and quite simple, and the angle of disengaging the multiple fasteners 21 by changing the matching design of the slide rail 141 and the protrusion 152 can be limited, and the fasteners 21 will not be damaged.

In summary, since the jig 1 for releasing the fasteners of the present invention is operated by the user pressing down the protruding pressing portion 18 disposed on the top, the pressing will naturally drive the levers 15 and the claws 1531 of the claw elements 153 located on the left and right sides below to rotate left and right at the same time, so as to release the multiple fasteners 21 of the connector 2 at the same time; and when the user releases his hand, the pressing portion 18 bounces back to the second position, and the levers 15 and the claw elements 153 on the left and right sides will return to the restored position. Thus, the present invention can effectively achieve the purpose of releasing the multiple fasteners 21 of the connector 2 at the same time through this design.

In this embodiment, the server of the present invention can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, cloud server, or Internet of Vehicles server.
