Description

Technical Field

[0001] The utility model relates to the field of computer mainboard connection components, in particular to a connection component applied to an automatic assembly system mainboard. Background Art

[0002] The internal accessories of the computer include fans, speakers, etc. At present, the assembly is done by connecting the connector on the mainboard, and then connecting the connector on the fan or speaker and other accessories, and then connecting the connectors together. Then, there are two connectors, male and female. In the current stage, they are all connected by wires. During assembly, due to the plugging of wires, automation cannot be achieved due to the soft structure of the wires. For example, the mainboard connector disclosed in patent announcement number: CN 201601329 U and the fan connector used in conjunction with the mainboard connector are generally plugged together manually, which is extremely inefficient.

[0003] If we just search, we can find some practical connection components for adapting to automation. For example, patent announcement number: CN 215912416 U discloses a fan structure for automatic assembly of a system motherboard. It discloses setting a male end on the fan and setting a female end connector on the motherboard. During assembly, it is necessary to ensure that the male and female terminals are plugged in. However, there are problems with this method: 1. The cost of setting a connector on the motherboard must be reduced as much as possible based on the continuous decline in 3C prices at this stage. 2. On the other hand, when plugging in, the terminals are easy to be cheap and require extremely high precision, otherwise the PIN will be broken. Utility Model Content

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Example 1

[0038] like Figure 1 , Figure 2 As shown, the utility model proposes a connection component for an automated assembly system motherboard, wherein the system motherboard 1 is provided with a circuit conducting portion 2. In this embodiment, the system motherboard 1 may be a computer motherboard, and the circuit conducting portion 2 is a non-connector structure, which is commonly known in the art as a gold finger, i.e., a strip-shaped metal structure, and is attached to the motherboard in a plane.

[0039] It also includes a device 3 to be installed which is electrically connected to the system mainboard 1, such as Figure 3 , 4As shown, the device to be installed 3 is provided with a fixing plate 4, and the fixing plate 4 is provided with a guide hole 5. In this embodiment, the device to be installed 3 can be a fan or a computer speaker, but is not limited to the above accessories; before entering the automated line to assemble the fan, a connector 6 is assembled on the fixing plate 4 of the fan, and a connecting mechanism is provided between the housing of the connector and the fixing plate, and the connecting mechanism is used to fix the connector and the fixing plate.

[0040] The terminal of the connector 6 (i.e., the elastic component 8 in this embodiment) is electrically connected to the device to be mounted 3 through a wire. The specific structure of the connector 6 is as follows:

[0041] The connector 6 is provided with a positioning assembly 7, which includes at least two groups of columnar blocks and is fixed to the plastic body 16. The columnar blocks correspond to the guide holes 5 and are inserted into the guide holes 5 to determine the connection position between the connector 6 and the fixing plate 4. At the same time, the connector 6 is also provided with a shell outside, such as Figure 8 As shown, the housing is made of metal and plays a role of shielding and dustproofing, and includes a bottom shell 18 and a top shell 19. The bottom shell 18 is pressed along the bottom of the plastic body 16, and the side wall of the plastic body 16 is provided with a first positioning block 20. The side wall of the bottom shell 18 is provided with a first positioning hole 22. The first positioning block 20 is pressed into the first positioning hole 22. The bottom shell 18 is provided with a connecting mechanism on both sides. In this embodiment, Fig.13 The connecting mechanism includes connecting ears 21 located on both sides of the bottom shell 18 or the top shell 19, where "both sides" refer to the edge sides of the top shell 19 or the bottom shell 18 in a direction parallel to the length of the elastic component 8. The fixing plate is provided with corresponding mounting holes, and the connecting ears 21 are locked and connected to the mounting holes 14 by screws 33. When the connector 6 is assembled on the fixing plate, the screws 33 are passed through the mounting holes and the connecting ears 21 to fix them, which is more suitable for automated production lines.

[0042] Of course Fig.14 As shown, another embodiment of the connection mechanism is as follows: it includes connection ears 21 located on both sides of the bottom shell or the top shell, the connection ears 21 can be integrally formed on the bottom shell, and of course, can also be integrally formed on the top shell, the fixing plate is provided with a hot melt column 34 corresponding to the connection ear 21, the hot melt column 34 passes through the connection ear 21, the hot melt column 34 is integrally formed with the fixing plate, and is usually made of plastic material. During automated assembly, the connection ear 21 of the connector 6 can be sleeved on the hot melt column 34, that is, assembly is achieved, and then a hot melt device is set on the automated line to hot melt the hot melt column 34 to the connection ear 21 for hot melt connection, that is, connection between the connector and the fixing plate 4 is achieved. In this way, when assembling the motherboard in the next step, the fan can be directly grabbed for assembly.

[0043] In addition, in order to ensure the stable connection of the above-mentioned connector shell, the side wall of the top shell 19 is provided with at least one set of undercuts, the top shell 19 covers the upper part of the plastic body 16, and the two sides are pressed on the outer wall of the top shell 19 and are connected with the undercuts. Here, "two sides" refer to the edge of the plastic body and the edge side parallel to the length direction of the elastic component. The bottom shell 18 is covered on the bottom of the plastic body 16, and the plastic body 16 is provided with a square hole. The bottom shell 18 is also arranged accordingly, and cooperates with the top shell 19 to cover the plastic part to achieve shielding and dustproof effects.

[0044] In addition to the plastic body 16 and the housing, the connector 6 also includes the following structures: at least one elastic component 8 is embedded in the connector 6. The connector 6 includes a plastic body 16, and a square groove 17 is provided on the plastic body 16. When applied to a fan assembly, the elastic component 8 can be selected from 4 groups, such as Figure 7 As shown, the elastic component 8 includes a straight portion 9 and a first bent portion 10 integrally formed with the straight portion 9, the straight portion 9 extends from the end of the plastic body 16 to the square groove 17, and the first bent portion 10 and the second bent portion 11 are located in the square groove 17, the first bent portion 10 is bent 180° from the end of the straight portion 9 and extends to the middle of the straight portion 9, the end of the first bent portion 10 is integrally formed with a second bent portion 11, the second bent portion 11 is V-shaped and protrudes downward from the first bent portion 10, the second bent portion 11 is in contact with the circuit conducting portion 2 of the system mainboard 1 at the bending position and is electrically connected, and the V-shaped structure The opening of the structure points to the straight portion 9, and the bottom of the second bent portion 11 protrudes from the plane where the square groove 17 is located. When the elastic member contacts the system motherboard 1 and presses down, the second bent portion 11 cooperates with the first bent portion 10 to be forced upward and deformed in the square groove 17 to ensure that it is pressed tightly on the circuit conducting portion 2. The second bent portion 11 with a V-shaped design can increase the positive force between the connector 6 and the motherboard, thereby ensuring the connection stability with the circuit conducting portion 2 of the motherboard. In addition, a sunken groove 15 is provided at the bending position of the V-shaped structure, so that the two sides of the sunken groove at the bending position of the V-shaped structure protrude in the length direction, and the protruding portions 25 are electrically connected to the circuit conducting portion 2 of the system motherboard 1.

[0045] like Figure 1As shown, after the robot grasps the accessory to be installed connected to the connector 6, the method of aligning and assembling it with the system motherboard 1 is as follows: the positioning and locking component 12 on the connector 6 includes at least two groups of positioning columns 23, the positioning columns 23 are fixed on the plastic body 16, and a slot 24 is provided on the central axis, and a protrusion 25 is provided on the outer side of the positioning column 23. The positioning column 23 is aligned with the positioning groove 13 on the motherboard and then pressed down. The positioning groove 13 is two groups of circular holes. Since the positioning column 23 and the plastic body 16 are integrally formed, there is a slot 24 on the central axis, and the outer wall of the protrusion 25 is wedge-shaped, when the protrusion 25 passes through the positioning groove 13, it will continue to move downward along the positioning groove 13 The positioning column 23 is squeezed and retracted toward the center until the protrusion 25 completely passes through the limiting hole and is stuck on the limiting hole. The accessory is assembled on the mainboard by pressing. Since there is a second bent portion 11 of the elastic component 8 in the square groove 17 at the bottom of the connector 6, the assembly is completed and the circuit connection is achieved after it is pressed down onto the circuit conducting portion 2 of the mainboard. Since the positioning locking component 12 is easier to align, the stability of the assembly is greatly improved. The elastic component 8 of the connector 6 can be pressed on the circuit conducting portion 2 of the mainboard, which improves the assembly error. Compared with the traditional plug-in method, the connector 6 component reduces the risk of damage, and at the same time reduces the investment in the connector 6 on the mainboard, greatly reducing the cost.

[0046] Through the above-mentioned device, this embodiment also proposes an assembly method. First, one end of the elastic component 8 of the connecting component is pre-electrically connected to the device 3 to be installed, which can be a fan, and the above-mentioned connector is fixedly connected to the fan by locking screws 33 or hot melting. Specifically, the robot grabs the connector 6 and assembles it on the fan, that is, after positioning through the columnar block 23, it is ensured that the connecting ear 21 of the connector is aligned with the mounting hole 14 of the fixed plate, and is locked by screws 33, or the connecting ear 21 is fixed to the hot melt column 34 of the fixed plate by hot melting.

[0047] The device 3 to be installed is grabbed by a robot arm and moved to the position of the system main board 1. After alignment by a visual alignment system, the positioning locking component 12 of the connector 6 is pressed into the positioning groove 13 of the system main board 1, and the positioning column of the locking component is pressed into the positioning groove. At the same time, the elastic component 8 is pressed onto the circuit conducting part 2 of the system main board 1 to finally achieve assembly.

[0048] Example 2

[0049] In this embodiment, the utility model proposes a connection component for an automated assembly system motherboard, wherein the system motherboard 1 is provided with a circuit conducting portion 2. Fig. 9As shown, the system motherboard 1 can be a computer motherboard, and the circuit conducting part 2 is a non-connector structure, which is commonly called a gold finger in the art, that is, a strip-shaped metal structure, and is flatly attached to the motherboard, and two groups of circular holes 32 and two groups of waist-shaped holes 31 are provided on the computer motherboard.

[0050] In this embodiment, other structures are the same, such as Fig.10 , Fig.12 As shown, the structure of the connector 6 is basically the same as that of the elastic component 8 in Example 1, and the difference lies in the structure of the positioning locking component 12. In this embodiment, the positioning locking component 12 includes at least two groups of positioning columns 23, and the positioning columns 23 are integrally formed with the bottom shell 18. The material of the positioning columns 23 is consistent with that of the metal shell, which greatly increases the service life of the positioning columns 23. The positioning columns 23 in this embodiment are cylindrical structures to achieve positioning, such as Fig.11 As shown, it also includes elastic pressure feet 26 located on both sides of the bottom shell 18 or the top shell 19, where "both sides" refers to the two edge sides of the top shell or the bottom shell parallel to the length direction of the elastic component, and the elastic pressure foot 26 points to the direction of the system motherboard 1, and the elastic pressure foot 26 includes a U-shaped portion 28, one end of the mouth of the U-shaped portion 28 is integrally formed with the edge of the bottom shell 18 or the top shell 19, and the other end is bent and extended to the top of the metal shell. The U-shaped portion 28 is inserted into the system motherboard 1 during assembly, and a protrusion 27 is provided at the matching position of the U-shaped portion 28 and the positioning groove 13 of the motherboard. After the U-shaped portion 28 is inserted into the positioning groove 13, the protrusion 27 can limit the displacement of the entire connector 6. When it needs to be unlocked, the elastic pressure foot 26 is pressed so that the U-shaped portion 28 does not interfere with the positioning groove 13, and the connector 6 can be separated. In addition, the positioning and locking assembly 12 made of metal can greatly increase the plug-in life and make assembly more convenient.
