Description

[Technical Field]

[0001] This utility model relates to a connector assembly, and more particularly to a connector assembly that facilitates the placement and removal of mating components. [Background Technology]

[0002] A connector assembly is provided for mounting on a circuit board having an electrical connector. The connector assembly includes a clamp for carrying a mating element and mounting the mating element on the electrical connector. The clamp includes a main body, a frame opening extending through the main body in a vertical direction, and a plurality of snap-fit ​​portions extending downward from the main body. The main body includes a pair of side portions located on opposite sides of the frame opening. The snap-fit ​​portions snap onto the lower surface of the mating element to fix the mating element to the clamp, and a portion of the mating element is received in the frame opening.

[0003] When removing mating components from an electrical connector, the clamping device and the mating component are usually removed manually from the side. However, as mating components become increasingly larger, this manual side-grabbing method is no longer sufficient to easily remove large mating components from the insulating body.

[0004] Therefore, it is necessary to design an electrical connector to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The purpose of this invention is to provide a connector assembly in which an extractor that can rotate around the clamping member is provided, so that the docking element can be easily picked up and put down by lifting the extractor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connector assembly is mounted on a circuit board having an electrical connector, with the electrical connector mating upwards with a mating element, the mating element including a protrusion. The assembly is characterized by comprising: a clamping member for carrying the mating element and mounting it onto the electrical connector; the clamping member includes a main body and a frame extending vertically through the main body; the main body includes two side portions located on opposite sides of the frame; each side portion has at least one pivot portion on its outer side away from the frame in the left-right direction; in the vertical direction, the projection of the protrusion is located within the frame, and the protrusion is positioned above the top surface of the main body; and at least one extraction member, each extraction member including an operating lever and two rotating rods connected to opposite ends of the operating lever; each rotating rod has a pivot portion at its end away from the operating lever; the pivot portion is pivotally connected to the pivot portion, and the rotating rods are rotatable around the pivot portion; when the mating element is mated with the electrical connector, the operating lever is located outside the protrusion in the front-back direction, and the rotating rods are located outside the protrusion in the left-right direction; operating the extraction member rotates the rotating rods, and the operating lever is positioned directly above the protrusion, thus removing the mating element from the electrical connector.

[0008] Furthermore, the clamping member also includes two ends located on opposite sides of the frame opening and connecting the two sides, with an operating part protruding from the operating lever to form an operating part. When the mating element is mated with the electrical connector, on the same side of the front and rear sides of the protrusion, the operating part protrudes in the front-rear direction relative to the corresponding end toward the side away from the frame opening.

[0009] Furthermore, when the mating element is mated to the electrical connector, the operating lever is lower than the top surface of the protrusion.

[0010] Furthermore, the clamping member also includes two ends located on opposite sides of the frame opening and connecting the two sides, at least one of the ends having at least one recess formed from its upper surface, the recess being used to accommodate the operating lever when the mating element is mated to the electrical connector.

[0011] Furthermore, the recess extends at least partially in the front-rear direction toward the side away from the window to the outer surface of the end.

[0012] Furthermore, the docking element is provided with a base plate, with a protrusion located above the base plate and the base plate located below the frame opening. Each of the left and right opposite sides of the docking element is recessed inward to form a recessed portion, which is located above the base plate. Each side protrudes towards the frame opening from its inner side in the left-right direction to form a stop portion, which is located within the recessed portion. Two extraction components are provided, with each corresponding side having two pivot portions. In the front-back direction, the stop portion is located between the two pivot portions.

[0013] Furthermore, it also includes a cover for pressing down the docking element, with an operating lever located below the cover. The docking element includes a base plate and a stepped portion connecting the upper end of the base plate and the lower end of the protrusion. The stepped portion is accommodated in the frame opening. The cover is pressed against the stepped portion, and the operating lever is lower than or flush with the top surface of the stepped portion.

[0014] Furthermore, one of the side portion and the rotating rod is provided with a positioning part, and the other of the side portion and the rotating rod is provided with a first groove, a second groove, and a partition part protruding between the first groove and the second groove. When the mating element is mated with the electrical connector, the positioning part is located in the first groove. When the extraction member is operated, the rotating rod is rotated and the positioning part moves from the first groove through the partition part into the second groove. The second groove cooperates with the positioning part to stop the rotating rod from continuing to rotate.

[0015] Furthermore, the side has a plate portion, and at least one cantilever extends downward from the lower surface of the plate portion. A pivot portion is provided on the plate portion, and a positioning portion extends from the end of the cantilever away from the plate portion. The positioning portion is positioned below the pivot portion.

[0016] Furthermore, the pivot portion includes two elastic portions that protrude from the corresponding side portion in the left-right direction toward the direction away from the frame opening and are spaced apart. Each elastic portion has a hook portion at the end away from the corresponding side portion. The pivot portion is a hole through which the rotating rod passes in the left-right direction. The hook portion passes through the corresponding pivot portion and prevents the pivot portion from disengaging from the corresponding pivot portion.

[0017] Furthermore, it also includes a fixing frame mounted on the circuit board and surrounding the electrical connector. The fixing frame includes two side walls located on opposite sides of the electrical connector and at least one protrusion protruding upward relative to each side wall. The protrusion extends in the left-right direction to form a mating post on the side facing the electrical connector. Each rotating rod also has an arc-shaped slot at the end away from the operating rod. One end of the slot has an inlet and the other end has a stop end. When the mating element mates with the electrical connector, the mating post is lower than the pivot part and located at the stop end. The mating post and the stop end cooperate to fix the clamping member in the fixing frame. The operating member is used to rotate the rotating rod and the mating post is located at the inlet. The operating rod is lifted upward to disengage the mating post from the inlet and the slot.

[0018] Furthermore, the main body includes a first component and a second component assembled from bottom to top on the first component. The frame opening extends through the first component and the second component from top to bottom. A pivot is provided on the first component, and the first component is pressed against the mating element.

[0019] Furthermore, the side portion includes an upwardly arched portion and a relief groove formed below the arched portion, with the protrusion at least partially accommodated in the relief groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Each side of the clamping member has at least one pivot portion on its outer side away from the frame opening in the left-right direction. Each extraction member includes an operating rod and two rotating rods connected to opposite ends of the operating rod. Each rotating rod has a pivot portion at its end away from the operating rod, and the pivot portion is pivotally connected to the pivot portion. The rotating rod can rotate around the pivot portion. When the mating element is mated with the electrical connector, the operating rods of the two extraction members are located on the outer side of the protrusion in the front-back direction, and the two rotating rods of each extraction member are located on the outer side of the protrusion in the left-right direction. When removing the mating element from the electrical connector, the extraction member is operated to rotate the rotating rod and position the operating rod directly above the protrusion. Lifting the operating rod upward causes the clamping member to move upward along with the mating element, thereby removing the mating element from the electrical connector. The extraction member and clamping member have a simple structure, are easy to operate, and facilitate the easy removal of large-volume mating elements from the insulating body.

Detailed Implementation Methods

[0041] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0042] For ease of understanding, we define the Z-axis extension direction as the up-down direction (where the positive Z-axis direction is the up direction), the Y-axis extension direction as the left-right direction (where the positive Y-axis direction is the right direction), and the X-axis direction as the front-back direction (where the positive X-axis direction is the front direction).

[0043] Please see Figures 1 to 9 This is a first embodiment of the connector assembly 100 of the present invention. The connector assembly 100 is mounted on a circuit board 200 having an electrical connector 201. The connector assembly 100 includes a fixing frame 1, a clamping member 2, two extraction members 3 (of course, in other embodiments, the connector assembly 100 may also include one extraction member 3) and a cover 4.

[0044] Please see Figure 1 and Figure 7 The electrical connector 201 is aligned with a mating element 300. The mating element 300 includes a substrate 301, a protrusion 302, and a stepped portion 303. The protrusion 302 is located above the substrate 301. The stepped portion 303 connects the upper end of the substrate 301 and the lower end of the protrusion 302. The left and right opposite sides of the stepped portion 303 are recessed inward to form a recessed portion 3031.

[0045] Please see Figure 1 and Figure 4 The fixing frame 1 is mounted on the circuit board 200 and surrounds the electrical connector 201.

[0046] Please see Figure 4 and Figure 7 The clamping member 2 is used to carry the mating element 300 so that the mating element 300 is mounted on the electrical connector 201. The clamping member 2 includes a main body 21, a frame opening 22 that runs vertically through the main body 21, and a plurality of latching portions 23 extending downward from the lower surface of the main body 21.

[0047] Please see Figure 3 , Figure 6 and Figure 5 The substrate 301 is located below the frame opening 22, and the step portion 303 is accommodated in the frame opening 22. In the vertical direction, the projection of the protrusion 302 is located inside the frame opening 22, and the protrusion 302 is provided above the top surface of the main body portion 21.

[0048] Please see Figure 7 The main body 21 includes two side parts 211 located on the left and right sides of the frame opening 22 and two end parts 212 located on the front and rear sides of the frame opening 22 and connecting the two side parts 211.

[0049] Please see Figure 5 and Figure 7 Each side 211 has two pivot parts M on the outer side away from the frame opening 22 in the left-right direction. Each pivot part M includes two elastic parts m1 that protrude from the corresponding side 211 in the left-right direction away from the frame opening 22 and are spaced apart. Each elastic part m1 has a hook part m2 at the end away from the corresponding side 211. In this embodiment, the two elastic parts m1 are spaced apart in the vertical direction of the clamping member 2.

[0050] Please see Figure 7 Each side portion 211 has a plate portion 2111, and a pivot portion M is provided on the plate portion 2111. Two cantilever arms 2112 extend downward from the lower surface of the plate portion 2111. A positioning portion 2113 extends from the end of the cantilever arm 2112 away from the plate portion 2111, and the positioning portion 2113 is set below the pivot portion M. The cantilever arms 2112 and the positioning portion 2113 can make way for other components (such as the cover 4, the heat sink (not shown)) located above the clamping member 2, so as to facilitate the installation of other components.

[0051] Please see Figure 6 and Figure 7 Each side portion 211 protrudes towards the frame opening 22 from its inner side in the left-right direction to form a stop portion 213. In the front-back direction, the stop portion 213 is located between the two pivot portions M. The latching portion 23 latches onto the lower surface of the substrate 301. The stop portion 213 is located in the recess 3031. The latching portion 23 and the stop portion 213 cooperate to fix the docking element 300 and the clamping member 2 together. The stop portion 213 can prevent the docking element 300 from moving upward. During the movement of the clamping member 2 carrying the docking element 300, the docking element 300 will not detach from the clamping member 2.

[0052] Please see Figure 3 and Figure 7Each end 212 is recessed downward from its upper surface to form a relief recess 2121, and the relief recess 2121 extends at least partially in the front-back direction away from the window to the outer surface of the corresponding end 212.

[0053] Please see Figure 5 and Figure 7 Each extraction element 3 includes an operating lever 31 and two rotating rods 32 connected to the left and right opposite ends of the operating lever 31, that is, the extraction element 3 is roughly "U" shaped. When the docking element 300 is docked with the electrical connector 201, the two operating levers 31 of the two extraction elements 3 are located on the outside of the protrusion 302 in the front-back direction, and the two rotating rods 32 of each extraction element 3 are located on the outside of the protrusion 302 in the left-right direction. The extraction element 3 will not obstruct the top of the protrusion 302, so that the extraction element 3 can make way for other elements located on the top of the protrusion 302.

[0054] Please see Figure 4 and Figure 7 Each rotating rod 32 has a pivot part N at the end away from the operating rod 31. The pivot part N is pivotally connected to the pivot part M, and the rotating rod 32 can rotate around the pivot part N. When removing the docking element 300 from the electrical connector 201, the extraction member 3 is operated to rotate the rotating rod 32 and position the operating rod 31 directly above the protrusion 302. The operating rod 31 is lifted upward to move the clamping member 2 carrying the docking element 300 upward together, thereby removing the docking element 300 from the electrical connector 201.

[0055] Please see Figure 4 and Figure 8 Two extraction parts 3 cooperate with the clamping part 2. The two extraction parts 3 prevent the clamping part 2 from rotating around the pivot part M. The extraction parts 3 and the clamping part 2 can smoothly carry the docking element 300 together and move together. The two extraction parts 3 are symmetrically connected to the clamping part 2. When the operating lever 31 is lifted so that the clamping part 2 carries the docking element 300 together and moves together, the clamping part 2 is subjected to uniform force.

[0056] Please see Figure 7 and Figure 8 In this embodiment, the pivot N is a hole that passes through the rotating rod 32 in the left-right direction. Of course, in other embodiments, the pivot N may be two elastic parts with hooks and spaced apart, and the pivot M may be a hole-like structure. The hook m2 of the same pivot M passes through the corresponding pivot N and prevents the pivot M from disengaging from the corresponding pivot N.

[0057] Please see Figure 3 and Figure 7An operating part 311 is formed by protruding from the operating lever 31. When the docking element 300 is docked with the electrical connector 201, on the same side of the front and rear sides of the protrusion 302, the operating part 311 protrudes in the front-rear direction relative to the corresponding end 212 away from the frame opening 22, so that the operator can apply force to the lower part of the operating part 311, thereby facilitating the operation of moving the operating part 311 upward and rotating the rotating lever 32.

[0058] Please see Figure 3 and Figure 7 When the mating element 300 mates with the electrical connector 201, the clearance recess 2121 is used to accommodate the operating lever 31. If the two operating levers 31 of the two extraction elements 3 are located on the outer side of the corresponding end 212 in the front-back direction, the operating lever 31 will occupy a large space in the front-back direction. In this embodiment, the clearance recess 2121 for accommodating the operating lever 31 is formed by recessing downward from the upper surface of the end 212, and the clearance recess 2121 extends away from the window in the front-back direction to the outer surface of the corresponding end 212. The operating lever 31 can save space in the front-back direction, and the clearance recess 2121 also ensures that the operating lever 31 does not occupy too much space in the vertical direction. The clearance recess 2121 can make way for other elements installed on the front and back sides and above of the clamping element 2.

[0059] Please see Figure 2 and Figure 3 When the mating element 300 is mated to the electrical connector 201, the operating lever 31 is lower than the top surface of the protrusion 302. A heat sink is provided above the connector assembly 100. The top surface of the mating element 300 contacts the heat sink to dissipate heat from the mating element 300. Since the operating lever 31 is lower than the top surface of the protrusion 302, after the heat sink is assembled into the connector assembly 100, the operating lever 31 will not abut against the heat sink, thereby avoiding the situation where the mating element 300 cannot contact the heat sink, resulting in poor heat dissipation of the mating element 300.

[0060] Please see Figure 7 , Figure 8 and Figure 9The rotating rod 32, at the end away from the operating rod 31, is provided with a first groove 321, a second groove 322, and a partition 323 protruding between the first groove 321 and the second groove 322. Alternatively, in other embodiments, the rotating rod 32 may have a positioning part 2113 at the end away from the operating rod 31, and the side portion 211 may have the first groove 321, the second groove 322, and the partition 323. When the docking element 300 docks with the electrical connector 201, the positioning part 2113 is located in the first groove 321. Operating the extraction member 3 rotates the rotating rod 32, causing the positioning part 2113 to pass from the first groove 321 through the partition 323 into the second groove 322. This keeps the operating rod 31 directly above the protrusion 302, facilitating the lifting of the operating part 311 to separate the docking element 300 from the electrical connector 201. The second groove 322 cooperates with the positioning part 2113 to prevent the rotating rod 32 from continuing to rotate.

[0061] Please see Figure 1 and Figure 3 The cover 4 is pivotally connected to one end of the fixed frame 1 in the front-rear direction. The cover 4 includes a plurality of protrusions 41 formed by downward protrusion. The protrusions 41 are pressed against the step portion 303, so that the mating element 300 is stably pressed against the terminal (not shown) in the electrical connector 201. The operating lever 31 is located below the cover 4, and the operating lever 31 is lower than or flush with the top surface of the step portion 303. The operating lever 31 makes way for the cover 4, so that the cover 4 can be pressed against the step portion 303.

[0062] Please see Figures 10 to 16 This is a second embodiment of the connector assembly 100 of the present invention. The connector assembly 100 is mounted on a circuit board 200 having an electrical connector 201. The connector assembly 100 includes a fixing frame 1, a clamping member 2, and two extraction members 3 (of course, in other embodiments, the connector assembly 100 may also include one extraction member 3).

[0063] Please see Figure 14 and Figure 15 The electrical connector 201 is connected to a mating element 300. The mating element 300 includes a substrate 301, a protrusion 302 and a step 303. The protrusion 302 is located above the substrate 301, and the step 303 connects the upper end of the substrate 301 and the lower end of the protrusion 302.

[0064] Please see Figure 10 and Figure 14The fixing frame 1 is mounted on the circuit board 200 and surrounds the electrical connector 201. The fixing frame 1 includes two sidewalls 11 located on opposite sides of the electrical connector 201 and four protrusions 12 protruding upward relative to each sidewall 11. The protrusions 12 are installed on the sidewalls 11 by riveting. Of course, in other embodiments, the protrusions 12 can also be integrally formed with the sidewalls 11. Each protrusion 12 protrudes in the left-right direction on the side facing the electrical connector 201 to form a mating post 121.

[0065] Please see Figure 14 , Figure 15 and Figure 16 The clamping member 2 is used to carry the mating element 300 so that the mating element 300 is mounted on the electrical connector 201. The clamping member 2 includes a main body 21, a frame opening 22 that runs vertically through the main body 21, and a plurality of latching portions 23 extending downward from the lower surface of the main body 21.

[0066] Please see Figure 11 Figure 12 The substrate 301 is located below the frame opening 22, and the step portion 303 is accommodated in the frame opening 22. In the vertical direction, the projection of the protrusion 302 is located inside the frame opening 22, and the protrusion 302 is provided above the top surface of the main body portion 21.

[0067] Please see Figure 15 The main body 21 includes two side parts 211 located on the left and right sides of the frame opening 22 and two end parts 212 located on the front and rear sides of the frame opening 22 and connecting the two side parts 211.

[0068] Please see Figure 15 and Figure 16 Each side 211 has two pivot parts M on the outer side away from the frame opening 22 in the left-right direction. In this embodiment, the pivot part M is a columnar structure that protrudes from the outer side of the side 211 away from the frame opening 22 in the left-right direction.

[0069] Please see Figure 10 and Figure 14 Each side portion 211 also includes an upwardly arched arch portion 2114 and a relief groove 2115 formed below the arch portion 2114, the protrusion 12 being at least partially accommodated in the relief groove 2115.

[0070] Please see Figure 15 and Figure 16In this embodiment, the clamping member 2 includes a first component 2a and a second component 2b assembled from bottom to top and fixed to the first component 2a. Of course, in other embodiments, the clamping member 2 can also be a single integrally formed component. The frame opening 22 extends vertically through the first component 2a and the second component 2b. The pivot part M is provided in the first component 2a, and the latching part 23 is provided in the second component 2b. The protrusion 302 is accommodated in the frame opening 22 located in the first component 2a and protrudes upward from the first component 2a. The step part 303 is accommodated in the frame opening 22 located in the second component 2b. The first component 2a is pressed against the step part 303, and the latching part 23 is latched onto the lower surface of the substrate 301. The latching part 23 cooperates with the first component 2a to fix the docking element 300 and the clamping member 2 together.

[0071] Please see Figure 10 and Figure 11 Each extraction element 3 includes an operating lever 31 and two rotating rods 32 connected to the left and right opposite ends of the operating lever 31, that is, the extraction element 3 is roughly "U" shaped. When the docking element 300 is docked with the electrical connector 201, the two operating levers 31 of the two extraction elements 3 are located on the outside of the protrusion 302 in the front-back direction, and the two rotating rods 32 of each extraction element 3 are located on the outside of the protrusion 302 in the left-right direction. The extraction element 3 will not obstruct the top of the protrusion 302, so that the extraction element 3 can make way for other elements located on the top of the protrusion 302.

[0072] Please see Figure 14 and Figure 16 Each rotating rod 32 has a pivot portion N at the end away from the operating rod 31. In this embodiment, the pivot portion N is a hole that passes through the rotating rod 32 in the left-right direction. Of course, in other embodiments, the pivot portion N can be a columnar structure and the pivot portion M can be a hole-like structure. The pivot portion N is pivotally connected to the pivot portion M, and the rotating rod 32 can rotate around the pivot portion N. By operating the extraction member 3, the rotating rod 32 is rotated and the operating rod 31 is positioned directly above the protrusion 302. The operating rod 31 is lifted upward, causing the clamping member 2 to move upward together with the docking element 300, and the docking element 300 is removed from the electrical connector 201.

[0073] Please see Figure 14 Two extraction parts 3 cooperate with the clamping part 2. The two extraction parts 3 prevent the clamping part 2 from rotating around the pivot part M. The extraction parts 3 and the clamping part 2 can smoothly carry the docking element 300 together and move together. The two extraction parts 3 are symmetrically arranged on the clamping part 2. When the operating lever 31 is lifted so that the clamping part 2 carries the docking element 300 together and moves together, the clamping part 2 is subjected to uniform force.

[0074] Please see Figure 13 , Figure 14 and Figure 16Each rotating rod 32 has an arc-shaped slot 324 at the end away from the operating rod 31. One end of the slot 324 has an inlet 3241, and the other end has a stop end 3242. When the mating element 300 is mated to the electrical connector 201, the mating post 121 is lower than the pivot part M and located at the stop end 3242. The mating post 121 and the stop end 3242 cooperate to fix the clamping member 2 to the fixing frame 1, and the first part 2a is pressed downward against the step part 303. When the mating element 300 is removed from the electrical connector 201, the extraction member 3 is operated to rotate the rotating rod 32 and the mating post 121 is located at the inlet 3241. The operating rod 31 is lifted upward to disengage the mating post 121 from the inlet 3241 and the slot 324.

[0075] In summary, the electrical connector 201 of this utility model has the following beneficial effects:

[0076] (1) The extraction member 3 is roughly U-shaped. When the docking element 300 is docked with the electrical connector 201, the operating rods 31 of the two extraction members 3 are located on the outside of the protrusion 302 in the front-back direction, and the two rotating rods 32 of each extraction member 3 are located on the outside of the protrusion 302 in the left-right direction. When the docking element 300 is taken out from the electrical connector 201, the extraction member 3 is operated to rotate the rotating rod 32 and the operating rod 31 is located directly above the protrusion 302. The operating rod 31 is lifted upward to make the clamping member 2 carry the docking element 300 upward together, thereby taking out the docking element 300 from the electrical connector 201. The extraction member 3 and the clamping member 2 have a simple structure and are easy to operate, making it easy to take out the large-volume docking element 300 from the insulating body.

When the docking element 300 docks with the electrical connector 201, the positioning portion 2113 is located in the first groove 321. The operating member 3 is operated to rotate the rotating rod 32 and cause the positioning portion 2113 to pass from the first groove 321 through the partition 323 into the second groove 322, so that the operating rod 31 is held directly above the protrusion 302, making it convenient to lift the operating portion 311 to separate the docking element 300 from the electrical connector 201. The second groove 322 cooperates with the positioning portion 2113 to stop the rotating rod 32 from continuing to rotate.

[0078] (3) The fixed frame 1 includes two side walls 11 located on the left and right sides of the electrical connector 201 and four protrusions 12 protruding upward relative to each side wall 11. Each rotating rod 32 has an arc-shaped slot 324 at one end away from the operating rod 31. One end of the slot 324 has an inlet 3241 and the other end of the opening has a stop end 3242. When the mating element 300 is mated to the electrical connector 201, the mating post 121 is located at the stop end 3242. The mating post 121 and the stop end 3242 cooperate to fix the clamping member 2 to the fixed frame 1, and the first part 2a is pressed downward to the step part 303, so that the mating element 300 and the electrical connector 201 can be stably mated. When the mating element 300 is removed from the electrical connector 201, the extraction member 3 is operated to rotate the rotating rod 32 and the mating post 121 is located at the inlet 3241. The operating rod 31 is lifted upward to make the mating post 121 disengage from the inlet 3241 and the groove 324. The mating post 121 can disengage from the inlet 3241 and the groove 324 to separate the clamping member 2 from the fixed frame 1.
