Description

Technical Field

[0001] The utility model relates to the technical field of chip assembly, in particular to an assembly fixture. Background Art

[0002] The CPU (Central Processing Unit) assembly fixture is used to clamp the CPU chip to the electrical connector, ensuring a stable electrical connection between the CPU chip and the connector's terminals. It primarily consists of a pressure plate, a tray, and a bracket. The tray secures the CPU chip, the bracket secures the connector, and the pressure plate presses down on the CPU chip to ensure a stable fit between the CPU chip and the connector's terminals.

[0003] Currently, assembly fixtures usually fix the pressure plate and the tray into a tray assembly and then hinge the tray assembly to the side of the bracket. During assembly, the tray assembly needs to be flipped toward the bracket. During the process of flipping and pressing the tray assembly downward, the CPU chip on the tray will produce a certain amount of slippage with the terminals in the electrical connector. This slippage will cause wear of the terminal contacts under the continuous pressure of the pressure plate. Utility Model Content

[0004] The main purpose of the utility model is to provide an assembly fixture, which aims to solve the problem of terminal contact wear caused by the tray turning process.

[0005] To achieve the above-mentioned purpose, the assembly fixture proposed in the utility model includes a bracket and a tray assembly, the bracket is provided with a bracket for installing an electrical connector, the bracket is provided with a rotating shaft on one side of the bracket, and the rotating shaft is fixedly sleeved with an anti-slip part; the tray assembly includes a pressure plate and a tray, the tray is provided with a card slot for installing a chip module, the pressure plate is rotatably connected to the rotating shaft, the tray is detachably inserted into the anti-slip part and is set at an angle to the pressure plate, and the tray is located between the bracket and the pressure plate, so that after the tray is buckled with the bracket, the pressure plate is buckled with the bracket again.

[0006] In one embodiment, an elastic member is further sleeved on the rotating shaft, and the elastic member is used to generate an impedance force that hinders the rotation of the rotating shaft, thereby preventing the chip module from instantaneously colliding with the electrical connector.

[0007] In one embodiment, two spaced-apart ears are protruded from one side of the tray facing the rotating shaft, and an anti-slip rod is provided between the two ears; the anti-slip component includes two oppositely arranged legs and a connecting portion connecting the two legs, an axial hole is provided on the legs, the rotating shaft is passed through the axial hole to be fixedly connected to the anti-slip component, and an insertion groove is provided on the end of the leg away from the rotating shaft, and the anti-slip rod is inserted into the two insertion grooves to realize the connection between the tray and the anti-slip component.

[0008] In one embodiment, a side of the support leg facing the pressure plate is arranged in contact with the pressure plate. When the pressure plate is unlocked from the bracket, the anti-slip component is driven by the elastic component to push against the pressure plate to rotate in the opposite direction.

[0009] In one embodiment, the elastic member is a torsion spring, which has a first torsion section and a second torsion section. A limiting portion is formed by bending between the first torsion section and the second torsion section. An abutment portion is formed at one end of the first torsion section and the second torsion section that are opposite to each other. The abutment portion abuts against the bracket, and the limiting portion abuts against the connecting portion of the anti-slip member. Under the pressing action of the anti-slip member, the limiting portion undergoes relative twisting with the abutment portion, thereby generating an impedance force that drives the anti-slip member to reverse.

[0010] In one embodiment, the pressure plate is locked and fixed to the bracket by a fastener. A fixing hole is provided at the end of the pressure plate away from the rotating shaft. The bracket is provided with a limiting column at the end of the bracket away from the rotating shaft. When the pressure plate is rotated to engage with the bracket, the limiting column is inserted into the fixing hole, and the fastener is screwed into the limiting column to lock the pressure plate.

[0011] In one embodiment, the tray is provided with bumps on four edges of the card slot, and the bumps are used to position the chip module.

[0012] In one embodiment, the tray is further provided with hooks on four edges of the card slot, and the hooks are used to support the chip module from the lower surface of the chip module.

[0013] In one embodiment, the assembly fixture further includes a cover shell, the pressure plate is provided with an escape groove arranged opposite to the clamping groove, and the cover shell is detachably covered on the pressure plate to block the escape groove.

[0014] In one embodiment, both side edges of the bracket are bent to form limiting edges, the distance between the two limiting edges is the width of the pressing plate, and the limiting edges are used to fit and limit the side edges of the pressing plate.

[0015] This assembly fixture separates the sliding process and the pressing process of the chip module by separating the tray and the pressure plate. No external pressure is applied to the chip module during its sliding contact with the terminal, thereby ensuring that the terminal contacts will not wear out. After the chip module slides into place, the pressure plate is pressed down to ensure close contact between the terminal and the chip module, thereby ensuring a stable electrical connection between the terminal and the chip module. Furthermore, this technical solution includes a fixed anti-slip member on the rotating shaft, and the tray and the anti-slip member are plugged and detachable, which not only facilitates the rapid installation and removal of the tray, but also prevents the tray from falling off the bracket.

[0028] The present invention provides an assembly fixture 100 .

[0029] See also Figures 1 to 5 , an embodiment of the assembly fixture 100 includes a bracket 10 and a tray assembly, the bracket 10 is provided with a bracket 11 for installing the electrical connector 200, the bracket 10 is provided with a rotating shaft 12 on one side of the bracket 11, and an anti-slip component 13 is fixedly sleeved on the rotating shaft 12, the tray assembly includes a pressing plate 30 and a tray 20, the tray 20 is provided with a card slot 21 for installing the chip module 300, the pressing plate 30 is rotatably connected to the rotating shaft 12, the tray 20 is detachably inserted into the anti-slip component 13 and is set at an angle to the pressing plate 30, and the tray 20 is located between the bracket 10 and the pressing plate 30, so that after the tray 20 is engaged with the bracket 10, the pressing plate 30 is then engaged with the bracket 10.

[0030] It should be noted that the electrical connector 200 includes an insulating body and terminals arranged in an array on the insulating body. The terminals are used to connect the motherboard and the chip module 300 to ensure that the chip module 300 can efficiently exchange data with other components on the motherboard. Existing assembly fixtures usually fix the tray 20 and the pressure plate 30 as a whole so that the pressure plate 30 can carry the tray 20 to move synchronously. This design method will cause the terminals to be subjected to greater sliding friction when in contact with the chip module 300, causing the contacts of the terminals to be easily worn. Different from this, the present assembly fixture 100 sets the tray 20 and the pressure plate 30 separately. Specifically, the bracket 10 is provided with a rotating shaft 12 on one side of the bracket 11. The rotating shaft 12 is fixedly provided with an anti-slip member 13 so that the anti-slip member 13 rotates together with the rotating shaft 12. At the same time, the pressure plate 30 is sleeved on the rotating shaft 12 to be rotatably connected to the rotating shaft 12. Then the tray 20 is detachably plugged into the anti-slip member 13. It should be noted that the anti-slip member 13 is arranged between the pressure plate 30 and the bracket 10 so that the flip angle of the anti-slip member 13 is smaller than the flip angle of the pressure plate 30. In the initial state, that is, when the pressure plate 30 and the tray 20 are both in the open state and no external force is applied, the tray 20 and the pressure plate 30 are arranged at an angle, such as Figure 2 shown.

[0031] The process of assembling the chip module 300 with the present assembly fixture 100 is as follows: flip the pressure plate 30 to the open state, fix the electrical connector 200 into the bracket 11 of the bracket 10, fix the chip module 300 into the slot 21 of the tray 20, and then snap the tray 20 into the anti-slip part 13 so that the tray 20 and the anti-slip part 13 can drive the rotating shaft 12 to rotate and then flip it, and then flip the pressure plate 30 to the engaged state. During the flipping process, the pressure plate 30 will drive the tray 20 to flip together. After the chip module 300 on the tray 20 slides into place with the electrical connector 200 on the bracket 10, the pressure plate 30 presses down the tray 20 to make the terminal in close contact with the chip module 300, and finally lock the pressure plate 30 and the bracket 10 to complete the assembly of the chip module 300 and the electrical connector 200.

[0032] In summary, the assembly fixture 100 can separate the sliding process and the pressing process of the chip module 300 by separating the tray 20 and the pressure plate 30. The chip module 300 does not have external pressure during the sliding contact with the terminal, thereby ensuring that the terminal contacts will not wear out. After the chip module 300 slides into place, the pressure plate 30 is pressed down to make the terminal and the chip module 300 in close contact, thereby ensuring that a stable electrical connection is formed between the terminal and the chip module 300. In addition, the present technical solution has an anti-slip member 13 fixedly sleeved on the rotating shaft 12, and the tray 20 and the anti-slip member 13 are plugged and detachable, which not only facilitates the rapid installation and removal of the tray 20, but also prevents the tray 20 from falling off the bracket 10.

[0033] It is not difficult to understand that when the weight of the pressure plate 30 is large, the action of flipping the pressure plate 30 may cause the chip module 300 to instantly collide with the terminal of the electrical connector 200, thereby causing damage to the terminal. For this reason, in one embodiment of the present invention, an elastic member 14 is also provided on the rotating shaft 12. The elastic member 14 is used to generate an impedance force that hinders the rotation of the rotating shaft 12, thereby avoiding instantaneous collision between the chip module 300 and the electrical connector 200.

[0034] Reference Figure 5 Regarding the connection of the tray 20, two spaced-apart ears 22 are protruded from the side of the tray 20 facing the rotating shaft 12, and an anti-slip rod 23 is provided between the two ears 22. The anti-slip part 13 includes two oppositely arranged legs 131 and a connecting part 132 connecting the two legs 131. An axial hole is provided on the leg 131, and the rotating shaft 12 is passed through the axial hole to be fixedly connected to the anti-slip part 13. An inserting groove 133 is provided on the end of the leg 131 away from the rotating shaft 12, and the anti-slip rod 23 is inserted into the two inserting grooves 133 to realize the connection between the tray 20 and the anti-slip part 13.

[0035] In this embodiment, two spaced-apart ears 22 are protruded from the side of the tray 20 facing the rotating shaft 12, and an anti-slip rod 23 is provided between the two ears 22. The anti-slip rod 23 is then plugged into the two legs 131 of the anti-slip member 13 to prevent the tray 20 from deflecting during the flipping process, thereby ensuring the smooth flipping of the tray 20.

[0036] The side of the leg 131 facing the pressure plate 30 is in contact with the pressure plate 30. When the pressure plate 30 is unlocked from the bracket 10, the anti-slip member 13 is driven by the elastic member 14 to push against the pressure plate 30 and rotate in the opposite direction. When the pressure plate 30 is unlocked from the bracket 10, the pressing force of the pressure plate 30 on the anti-slip member 13 disappears, and the anti-slip member 13 automatically drives the tray 20 and the pressure plate 30 to flip to the open position under the elastic force of the elastic member 14.

[0037] In one embodiment of the present invention, the elastic member 14 is a torsion spring, which has a first torsion section 141 and a second torsion section 142. The first torsion section 141 and the second torsion section 142 are bent to form a limiting portion 143. The first torsion section 141 and the second torsion section 142 are formed with an abutment portion 144 at one end facing away from each other. The abutment portion 144 abuts against the bracket 10, and the limiting portion 143 abuts against the connecting portion 132 of the anti-slip component 13. Under the pressing action of the anti-slip component 13, the limiting portion 143 is relatively twisted with the abutment portion 144, thereby generating an impedance force that drives the anti-slip component 13 to reverse, thereby avoiding the tray 20 from colliding with the bracket 10.

[0038] In the present invention, the pressure plate 30 is locked and fixed to the bracket 10 by fasteners. Specifically, the pressure plate 30 is provided with a fixing hole 33 at the end away from the rotating shaft 12, and the bracket 10 is provided with a limiting column 16 (such as a screw) at the end of the bracket 11 away from the rotating shaft 12. When the pressure plate 30 is rotated to engage with the bracket 10, the limiting column 16 is inserted into the fixing hole 33, and the fastener (such as a bolt) is screwed into the limiting column 16 to lock the pressure plate 30.

[0039] Please continue to refer to Figure 5 The tray 20 is provided with bumps 24 on the edges of the card slot 21 . The bumps 24 are used to position the chip module 300 .

[0040] The tray 20 is further provided with hooks 25 on the edges around the card slot 21 . The hooks 25 are used to support the chip module 300 from the lower surface of the chip module 300 .

[0041] Reference Figure 1 or Figure 3 One embodiment of the assembly fixture 100 further includes a cover 40. The pressure plate 30 is provided with an escape groove 32 arranged opposite to the card slot 21. The cover 40 is detachably covered on the pressure plate 30 to block the escape groove 32. The cover 40 and the pressure plate 30 can be connected by snaps or magnetically. When the chip module 300 is not yet installed, the cover 40 is covered on the pressure plate 30 to play a dust-proof role. As we know, the thickness of the chip module 300 is often greater than the thickness of the tray 20. After the chip module is installed in the card slot 21, the upper surface of the chip module 300 will protrude from the upper surface of the tray 20. After the pressure plate 30 is flipped and pressed down, the protruding part of the chip module 300 will push open the cover 40 and automatically detach it from the pressure plate 30.

[0042] In addition, the two side edges of the bracket 10 are bent to provide limiting edges 15, and the distance between the two limiting edges 15 is the width of the pressure plate 30. The limiting edges 15 are used to fit and limit with the side edges of the pressure plate 30 to prevent the pressure plate 30 from deflecting during the pressing process.

[0043] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
