Abstract
Description
[Technical Field]
[0001] This utility model relates to a connector assembly, and more particularly to a high-strength connector assembly. [Background Technology]
[0002] Traditional electrical connectors consist of an insulating body mounted on a circuit board. The insulating body includes a mating surface, a recessed slot formed from the mating surface downwards, and sidewalls on both sides of the slot. The slot is used to insert an electronic card, and the insulating body is secured to the circuit board with fasteners. With the optimization and improvement of electronic cards, their weight has increased, placing higher demands on the strength of the electrical connectors. Traditional electrical connectors have low strength and poor load-bearing capacity. When inserting a heavy electronic card, the card may tilt or wobble, exerting a significant force on the upper part of the insulating body's sidewalls at the slot's front and rear. This can easily lead to cracking of the insulating body at the corresponding location on both sides of the slot.
[0003] To enhance the strength of electrical connectors, existing technologies use a stamped metal shell made of sheet metal to encase the insulating body. This increases the connector's strength, with or without pins for fixing it to the circuit board. However, while this method increases the connector's strength, the connector itself remains insufficiently strong, and the connection stability between the connector and the circuit board is relatively poor. Therefore, when inserting a heavy electronic card, the card's tilting or wobbling can easily cause the connector to crack, become misaligned, or deform. Consequently, the required strength or connection stability between the connector and the circuit board is still not met.
[0004] Therefore, it is necessary to design a new connector assembly to solve the above-mentioned technical problems. [Utility Model Content]
[0005] The purpose of this invention is to provide a high-strength connector assembly, which prevents the electrical connector from cracking by using multiple limiting members located on the front and rear sides of the slot and limiting them to the outside of the two side walls.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A connector assembly for inserting a mating member and mounting it on a circuit board includes: an electrical connector including a mating surface, a slot, and two sidewalls, the slot being recessed downward from the mating surface to insert the mating member, and the two sidewalls being located on opposite sides of the slot in a front-rear direction; and a plurality of limiting members, independently disposed from the electrical connector, the limiting members being made of metal and mounted on the circuit board, the plurality of limiting members being located on the front and rear sides of the slot and limited to the outer sides of the two sidewalls. Viewed from below, the limiting members are either in contact with or have a gap with the electrical connector. In a vertical direction, the height of the limiting members above the circuit board is not less than half the height between the mating surface and the circuit board, and the height of the limiting members is not less than the bottom surface of the slot.
[0008] Furthermore, the connector assembly also includes a backplate located below the circuit board. The limiting member includes a limiting element and a locking element. The locking element is riveted to the backplate, and the portion of the locking element located above the backplate passes through the circuit board and is threadedly connected to the limiting element.
[0009] Furthermore, the limiting member is provided with a tool hole and a mounting hole. The tool hole extends upward through the limiting member, and the mounting hole extends downward through the limiting member and communicates with the tool hole upward. The mounting hole is at least partially provided with a threaded structure for threaded connection with the locking fastener.
[0010] Furthermore, the limiting member includes a main body and a reinforcing part, the reinforcing part being connected to the upper end of the main body, and in the front-rear direction, the gap between the reinforcing part and the side wall is smaller than the gap between the main body and the side wall.
[0011] Furthermore, the limiting member also includes a clearance portion, which is connected to the lower end of the main body portion. In the front-rear direction, the gap between the clearance portion and the side wall is greater than the gap between the main body portion and the side wall.
[0012] Furthermore, the clearance portion includes a gradient section and a straight section. The gradient section is connected to the lower end of the main body portion. The width of the gradient section gradually decreases in the front-back direction. The straight section is connected to the lower end of the gradient section. The straight section is cylindrical in shape.
[0013] Furthermore, multiple limiting components located on the front and rear sides of the slot are arranged in a one-to-one correspondence.
[0014] Furthermore, the electrical connector also includes an ear clip, a pivot portion, and a connecting wall. The pivot portion is located outside the slot in the left-right direction, and the connecting wall is located between the slot and the pivot portion in the left-right direction. The ear clip is pivotally connected to the pivot portion, and the two limiting members are positioned corresponding to the connecting wall in the front-back direction.
[0015] Furthermore, the electrical connector also includes a foolproof part, a pivot part, and an ear clip pivotally connected to the pivot part. The foolproof part is located in the slot and connected to the two side walls, such that the slot is divided into a long slot and a short slot in the left-right direction. In the left-right direction, the short slot is located on the side of the long slot away from the pivot part. The two limiting members are provided in the front-back direction corresponding to the foolproof part or the short slot.
[0016] Furthermore, the electrical connector includes a base and a metal shell, the metal shell being fitted onto the base, the metal shell being formed by stamping a sheet metal and including two side plates, the two side plates being located on the front and rear sides of the slot, and the limiting member being limited to the outside of the side plates.
[0017] Furthermore, the metal shell also includes an end plate and two folding plates. In the left-right direction, the end plate is located outside the slot, and the two folding plates are connected to the front and rear edges of the end plate. The two folding plates are fastened to the two side plates. When viewed in the front-back direction, the limiting member does not overlap with the folding plates.
[0018] Compared with the prior art, the connector assembly designed in this utility model has the following advantages:
[0019] In this invention, the limiting component and the electrical connector are independently set and made of metal, which has higher strength. The limiting component is installed on the circuit board and is located on the front and rear sides of the slot and is limited to the outer side of the two side walls. When viewed from below, the limiting component and the electrical connector are connected or there is a gap. The height of the limiting component above the circuit board is not less than half the height between the mating surface and the circuit board, and the height of the limiting component is not lower than the bottom surface of the slot, which prevents the electrical connector from cracking on the front and rear sides. This can improve the stability of the connection between the electrical connector and the circuit board. [Attached Image Description]

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise expressly and specifically limited.
[0030] like Figures 1 to 6The diagram shows the connector assembly 100 of this utility model. The vertical direction of the connector assembly 100 is defined as the Z-axis, the upward direction as the positive Z-axis, the front-back direction as the X-axis, the forward direction as the positive X-axis, the left-right direction as the Y-axis, and the rightward direction as the positive Y-axis. For ease of description, the vertical, left-right, and front-back directions in this utility model are relative positions and do not constitute a limitation on implementation. Furthermore, the terms "equal distance" or "equal angle" in this application include not only absolute equality but also approximate equality as commonly understood in engineering, meaning there may be a certain degree of error, such as a tolerance range of -1% to 1%.
[0031] like Figure 1 and Figure 2 As shown, a connector assembly 100 is used to insert a mating member 200 and is mounted on a circuit board 300. It includes an electrical connector 1, multiple limiting members 2, and a back plate 3. The electrical connector 1 is used to insert into the mating member 200 and is electrically connected to it, and is mounted on the circuit board 300 and electrically connected to it. The multiple limiting members 2 are independently arranged with the electrical connector 1 and are made of metal, possessing high strength. The limiting members 2 are mounted on the circuit board 300 and do not interfere with the electrical connector 1, enabling a stable connection with the circuit board 300. The multiple limiting members 2 are located on the outside of the electrical connector 1 to limit the electrical connector 1 in the front-rear direction, preventing the electrical connector 1 from cracking. The back plate 3 is located below the circuit board 300 and connected to the limiting members 2 to enhance the connection stability between the limiting members 2 and the circuit board 300. Specifically, the mating member 200 can be an electronic card or a mating connector. In this embodiment, the connector assembly 100 is a card edge connector, and the mating member 200 is an electronic card. The circuit board 300 has a power supply connector 1 and an electrically connected pad 4.
[0032] like Figure 1 , Figure 2 and Figure 4As shown, the electrical connector 1 includes a mating surface 10, a slot 11, two side walls 12, a foolproof part 13, a pivot part 18, a connecting wall 19, an ear clip 17, and a plurality of conductive terminals 16. The slot 11 is recessed downward from the mating surface 10 for inserting the mating member 200. The two side walls 12 are located on opposite sides of the slot 11 in the front-back direction. The foolproof part 13 is located inside the slot 11 and connected to the two side walls 12, such that the slot 11 is divided into a long slot 111 and a short slot 112 in the left-right direction. The pivot part 18 is located on the outside of the slot 11 in the left-right direction, and the connecting wall 19 is located between the pivot part 18 and the slot 11. Specifically, the pivot part 18 is located on the outside of the end of the long slot 111 away from the short slot 112 in the left-right direction, and the connecting wall 19 is located between the pivot part 18 and the long slot 111. Multiple conductive terminals 16 are disposed on the front and rear sides of the slot 11. Each conductive terminal 16 includes a contact portion 161 and a mounting portion 162. The contact portion 161 is exposed in the slot 11 and is used to electrically communicate with the mating part 200. The mounting portion 162 is exposed outside the electrical connector 1 and is used to solder to the pad 4 of the circuit board 300.
[0033] like Figure 1 and Figure 2 As shown, the electrical connector 1 includes a base 14 and a metal shell 15. In this embodiment, the metal shell 15 is fitted over the base 14 to enhance its strength. In other embodiments, the metal shell 15 may be embedded in the base 14; of course, the electrical connector 1 may also be without the metal shell 15.
[0034] like Figure 1 and Figure 2 As shown, the base 14 includes a top surface 141 and a groove 142. The groove 142 is recessed downward from the top surface 141 for inserting the mating member 200. Specifically, the base 14 is an integrally injection-molded insulating injection molded part. In embodiments where the electrical connector 1 does not have a metal shell 15, the groove 142 is the slot 11, the mating surface 10 is the top surface 141, and the side wall 12, the foolproof part 13, the pivot part 18, and the connecting wall 19 are all parts of the structure on the base 14.
[0035] like Figure 1 , Figure 2 and Figure 4As shown, the metal shell 15 is formed by stamping a metal sheet, which facilitates manufacturing and increases the production volume of the electrical connector 1. The metal shell 15 includes a top plate 151, two side plates 153, an end plate 154, and two folded plates 155. The top plate 151 is located above the top surface 141 and is used to reinforce the top surface 141 of the base 14. The top plate 151 has a vertically penetrating slot 152, which corresponds vertically to the groove 142 and the two fit together to form a slot 11, facilitating the insertion of the mating part 200. Two side plates 153 are located on the front and rear sides of the slot 11 and connected to the front and rear edges of the top plate 151 to reinforce the front and rear sides of the base 14. Each side plate 153 and the plastic on the corresponding side of the base 14 on the front and rear sides of the slot 11 together form a side wall 12. The plastic on the side of the base 14 away from the slot 11 in the left-right direction, a portion of the top plate 151 extending onto this portion of the plastic, and a portion of each of the two side plates 153 together form a pivot portion 18. The plastic between the groove 142 and the pivot portion 18 of the base 14 and a portion of the top plate 151 thereon together form a connecting wall 19. The plastic between the long groove 111 and the short groove 112 of the base 14 and a portion of the top plate 151 thereon together form a foolproof part 13. An end plate 154 is located on the outer side of the slot 11 in the left-right direction and connected to the corresponding side edge of the top plate 151 in the left-right direction to reinforce the end of the base 14. Two folding plates 155 are connected to the front and rear edges of the end plate 154, and are fastened to the two side plates 153. This limits the opening of the side plates 153 away from the slot 11 in the front-rear direction, and simultaneously limits the opening of the end plate 154 away from the slot 11 in the left-right direction, further improving the strength of the electrical connector 1. Specifically, the side plate 153 has a protrusion 1531, and the folding plate 155 has an opening 1551 corresponding to the protrusion 1531. The protrusion 1531 is fastened into the opening 1551, making the folding plate 155 and the side plate 153 stably connected.
[0036] like Figure 1 , Figure 2 and Figure 3As shown, multiple limiting members 2 are located on the front and rear sides of the slot 11 and are limited to the outer sides of the two side walls 12. Looking downwards, the limiting members 2 do not overlap with the electrical connector 1. In the vertical direction, the height of the limiting members 2 above the circuit board 300 is not less than half the height between the mating surface 10 and the circuit board 300, and the height of the limiting members 2 is not less than the bottom surface of the slot 11, to prevent the electrical connector 1 from cracking in the front and rear sides. This improves the stability of the connection between the electrical connector 1 and the circuit board 300. It can be understood that because the limiting members 2 are used to limit the electrical connector 1 in the front and rear direction, the two side walls 12 of the electrical connector 1 are prevented from opening away from the slot 11 in the front and rear direction. Looking downwards, the limiting members 2 do not overlap with the electrical connector 1, meaning that the limiting members 2 can have a gap with the side plate 153 or can contact the side plate 153. Multiple limiting members 2 located on the front and rear sides of the slot 11 are arranged in a one-to-one correspondence, which ensures that the front and rear sides of the slot 11 of the electrical connector 1 are evenly stressed when the docking part 200 tilts or wobbles back and forth. This better prevents the electrical connector 1 from cracking to the front and rear sides. The symmetrical structure is also more aesthetically pleasing and easier to assemble. When the docking part 200 tilts or wobbles back and forth, the two side walls 12 of the electrical connector 1 are more prone to cracking at the connection positions at the left and right ends of the slot 11. Therefore, in this embodiment, there are four limiting members 2. Two limiting members 2 are arranged in the front-back direction corresponding to the position of the connecting wall 19 to prevent the end of the electrical connector 1 from cracking to the front and rear sides in the left-right direction. The other two limiting members 2 are located at the end away from the pivot part 18, and two limiting members 2 are arranged in the front-back direction corresponding to the anti-fooling part 13 or the short groove 112, so that the other end of the electrical connector 1 in the left-right direction can be better limited to prevent the other end of the electrical connector 1 in the left-right direction from cracking to the front and rear sides. Viewed from the front-back direction, the limiting member 2 does not overlap with the folding plate 155, and the limiting member 2 is not affected by the folding plate 155. This allows the limiting member 2 to be closer to the side plate 153, better limiting the electrical connector 1 and preventing the electrical connector 1 from cracking. It also reduces the space occupied by the entire connector assembly 100 on the circuit board 300 in the front-back direction. In this embodiment, the limiting member 2 is made of stainless steel, which has higher strength. In other embodiments, the limiting member 2 can also be made of aluminum alloy, copper alloy, or zinc alloy.
[0037] like Figure 1 and Figure 6As shown, the limiting member 2 includes a limiting element 21 and a locking element 22. The locking element 22 is riveted to the back plate 3, thereby preventing the locking element 22 from rotating and strengthening the connection stability between the locking element 22 and the limiting element 21. The portion of the locking element 22 located above the back plate 3 passes through the circuit board 300 and is threaded 2121 to the limiting element 21, thereby strengthening the strength of the limiting member 2 and the connection strength between the limiting member 2 and the circuit board 300. In this embodiment, the limiting element 21 is a metal nut, and the locking element 22 is a metal screw. In other embodiments, the limiting element 21 can be a screw, and the locking element 22 can be a nut.
[0038] like Figure 6 As shown, the limiting member 21 includes a tool hole 211, a mounting hole 212, a main body 213, a reinforcing part 214, and a clearance part 215. The tool hole 211 extends upward through the limiting member 21 for inserting an auxiliary installation tool, facilitating the connection between the limiting member 21 and the locking member 22. The mounting hole 212 extends downward through the limiting member 21. At least part of the mounting hole 212 has a threaded structure 2121 for threaded connection with the locking member 22. Specifically, the mounting hole 212 of the limiting member 21 may have a threaded portion near the circuit board 300 in the vertical direction, while the other portion of the mounting hole 212 may not have a threaded portion 2121. The height of the locking member 22 above the circuit board 300 is adapted to the height of the mounting hole 212 with the threaded portion 2121. Only a portion of the length of the mounting hole 212 is connected to the threaded portion 2121 of the locking member 22, which reduces the length of the threaded portion 2121, thereby reducing the coaxiality requirement of the threaded portion 2121 and thus reducing processing costs. The mounting hole 212 communicates upwards with the tool hole 211, forming a through hole that facilitates chip removal. In this embodiment, the height of the locking fastener 22 above the circuit board 300 is lower than the vertical height of the limiting member 21. When connected to the limiting member 21, the shorter locking fastener 22 allows for faster and easier rotation into position, facilitating assembly and reducing assembly costs. In other embodiments, the height of the locking fastener 22 above the circuit board 300 is not lower than the vertical height of the limiting member 21, and the longer length of the locking fastener 22 completely fills the mounting hole 212 of the limiting member 21, thereby strengthening the overall strength of the limiting member 2.
[0039] like Figure 4 and Figure 5As shown, the reinforcing part 214, the main body part 213, and the clearance part 215 are connected sequentially from top to bottom and are integrally formed. In the front-back direction, there is a first gap H1 between the reinforcing part 214 and the side wall 12, and a second gap H2 between the main body part 213 and the side wall 12. The first gap H1 is smaller than the second gap H2, so that the reinforcing part 214 is closer to the upper end of the electrical connector 1. When the mating part 200 tilts or shakes back and forth, the upper end of the electrical connector 1, which is subjected to the greatest force by the mating part 200, is less likely to crack to the front and back sides. In the front-back direction, there are a minimum gap and a maximum gap between the clearance part 215 and the side wall 12. The minimum gap is the third gap H3, and the maximum gap is the fourth gap H4. The third gap H3 is greater than or equal to the second gap H2, and the fourth gap H4 is greater than the third gap H3, the second gap H2, and the first gap H1. This prevents the clearance part 215 from contacting the pads 4 on the circuit board 300 and prevents the electrical connector 1 from short-circuiting. The clearance portion 215 includes a gradient section 2151 and a straight section 2152. The gradient section 2151 is connected to the lower end of the main body portion 213. The width of the gradient section 2151 gradually decreases in the front-rear direction to prevent the lower end of the limiting member 21 from suddenly becoming smaller, which could easily damage the limiting member 21. The straight section 2152 is connected to the lower end of the gradient section 2151 and is cylindrical in shape. A third gap H3 is formed between the upper end of the gradient section 2151 and the electrical connector 1, and a fourth gap H4 is formed between the straight section 2152 and the electrical connector 1.
[0040] In summary, the connector assembly of this utility model has the following beneficial effects:
[0041] (1) In this utility model, the limiting component 2 and the electrical connector 1 are independently set and are made of metal, which has higher strength. The limiting component 2 is installed on the circuit board 300. The limiting component 2 is located on the front and rear sides of the slot 11 and is limited to the outside of the two side walls 12. When viewed from below, the limiting component 2 is connected to the electrical connector 1 or there is a gap. The height of the limiting component 2 above the circuit board 300 is not less than half the height between the mating surface 10 and the circuit board 300, and the height of the limiting component 2 is not less than the bottom surface of the slot 11, which also enhances the stability of the connection between the connector assembly 100 and the circuit board 300.
[0042] (2) The limiting component 2 includes a limiting member 21 and a locking member 22. The locking member 22 is riveted to the back plate 3, which increases the stability of the connection between the locking member 22 and the back plate 3 and strengthens the stability of the connection between the limiting component 2 and the circuit board 300. The part of the locking member 22 located above the back plate 3 passes through the back plate 3 and the circuit board 300 and is threadedly connected to the limiting member 21, which further strengthens the stability of the connection between the limiting component 2 and the circuit board 300, thereby better limiting the electrical connector 1 and preventing the electrical connector 1 from cracking on the front and rear sides.
[0043] (3) The tool hole 211 extends upward through the limiting member 21 for the insertion of auxiliary installation tools, which facilitates the connection of the limiting member 21 and the locking member 22; the mounting hole 212 extends downward through the limiting member 21, and the mounting hole 212 is at least partially provided with a threaded structure 2121 for connection with the locking member 22 threaded 2121. The mounting hole 212 communicates upward with the tool hole 211, so that the mounting hole 212 and the tool hole 211 together form a hole that runs through the top and bottom, which facilitates the removal of machining chips and the manufacturing of the limiting member 21, thereby increasing the production of the electrical connector 1 assembly.
[0044] (4) A reinforcing part 214 is connected to the upper end of the main body 213. The gap between the reinforcing part 214 and the side wall 12 is smaller than the gap between the main body 213 and the side wall 12. This can better limit the upper end of the electrical connector 1 and prevent the upper end of the electrical connector 1, which is subjected to the greatest force by the mating part 200, from cracking in the front and rear sides. A clearance part 215 is provided at the lower end of the main body 213 to prevent the limiting part 21 from colliding with the pad 4 on the circuit board 300, to prevent the electrical connector 1 from short-circuiting, or to prevent the limiting part 21 from colliding with other components on the circuit board 300.
[0045] (5) The width of the gradient section 2151 connected to the lower end of the main body 213 gradually decreases in the front-back direction, thereby increasing the strength of the lower end of the limiting member 21 and avoiding the problem that the lower end of the limiting member 21 is easily damaged due to sudden reduction; a straight section 2152 is connected to the lower end of the gradient section 2151. The straight section 2152 is cylindrical in shape. Under the premise of ensuring strength, it can also better accommodate the mounting part 162 of the conductive terminal 16 and the pad 4 of the circuit board 300, and avoid short circuit of the electrical connector 1.
[0046] (6) Multiple limiting components 2 located on the front and rear sides of the slot 11 are arranged in a one-to-one correspondence, which can make the front and rear sides of the slot 11 of the electrical connector 1 evenly stressed when the docking part 200 is tilted or swayed. At the same time, the symmetrical structure is more aesthetically pleasing.
[0047] (7) The electrical connector 1 includes a base 14 and a metal shell 15 sleeved outside the base 14. The metal shell 15 enhances the strength of the electrical connector 1 itself. The metal shell 15 is formed by stamping a metal sheet, which is easy to manufacture and helps to increase the production of the electrical connector 1. The limiting member 2 is located outside the two side plates 153 of the metal shell 15. The limiting member 2 is an independent component, which facilitates the assembly or replacement of the limiting member 2. The independently set limiting member 2 can be set to have higher strength, which can better prevent the electrical connector 1 from cracking on the front and rear sides.
[0048] (8) Two limiting members 2 are set at the positions corresponding to the connecting wall 19 in the front-back direction to prevent one end of the electrical connector 1 from cracking in the left-right direction; the two limiting members 2 are set at the positions corresponding to the anti-fooling part 13 or the short groove 112 in the front-back direction to prevent the other end of the electrical connector 1 from cracking in the left-right direction.
[0049] (9) When viewed from the front and back direction, the limiting member 2 and the folding plate 155 do not overlap, which avoids the folding part from increasing the gap between the limiting member 2 and the electrical connector 1. The limiting member 2 is aligned with the part without the folding plate 155, which can make the limiting member 2 and the electrical connector 1 closer together, better prevent the electrical connector 1 from cracking on the front and back sides, and also reduce the space occupied by the entire connector assembly 100 on the circuit board 300 in the front and back direction.
[0050] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
