Description

Technical Field

[0001] This invention relates to a connector, and more particularly to a card edge connector. Background Technology

[0002] Chinese Utility Model Publication No. CN2256173Y (corresponding to US Patent No. US5,634,803) discloses an ejector device for an electrical connector, comprising a main body, an ejector portion, and a retaining portion, with a pair of protrusions on each side of the main body; an inner conical groove and an outer conical groove are provided on the inner surface of the sidewall of the tower-shaped portion of the electrical connector near the end wall. When the ejector device rotates relative to the main body, the protrusions on the ejector device pass between the inner and outer conical grooves. However, when the ejector device rotates, the protrusions on the ejector device interfere hard with the sidewall of the tower-shaped portion, causing the sidewall to bulge outward. Therefore, the sidewall of the tower-shaped portion is prone to cracking or damage, leading to the failure of the ejector device. Summary of the Invention

[0003] Therefore, one object of the present invention is to provide a card edge connector that can improve at least one problem in the prior art.

[0004] Therefore, in some embodiments, the snap-fit ​​connector of the present invention includes an insulating body, a locking member, and a metal insert.

The locking member is pivotally mounted on the tower-like structure of the insulating body and is pivotable relative to the insulating body between a locked position and an unlocked position. The locking member has a first latching portion. The metal insert is disposed on the tower-like structure of the insulating body. The metal insert has two spaced-apart sides, a bridging portion connecting the two sides, and a second latching portion integrally extended from the bridging portion and corresponding to the first latching portion and having elasticity. When the locking member is in the locked position, the first latching portion engages with the second latching portion; when the locking member is in the unlocked position, the first latching portion and the second latching portion separate from each other.

[0005] In some embodiments, the column has two side walls that jointly define the guide groove and an outer end wall, the two sides of the metal insert are respectively disposed on the two side walls, and the bridging portion is disposed on the outer end wall.

[0006] In some embodiments, each side portion has an inner body disposed on the inner surface of the corresponding side wall, and an extension leg connected to the inner body and disposed on the outer surface of the corresponding side wall, the bridging portion connecting the inner bodies of the two sides and disposed on the inner surface of the outer end wall.

[0007] In some embodiments, the second buckle is integrally formed extending outward from the upper edge of the bridging portion.

[0008] In some embodiments, each side portion has an outer body disposed outside the corresponding side wall, and an extension leg connected to the bottom end of the outer body and extending downwardly outside the corresponding side wall, the bridging portion connecting the outer bodies of the two sides and disposed outside the outer end wall.

[0009] In some embodiments, the second fastener is integrally formed extending outward from the lower edge of the bridging portion.

[0010] In some embodiments, the tower-like structure also has a lower base body, the column extending upward from the lower base body and being relatively narrow, the lower base body having a locking member mounting portion, the locking member being pivotally mounted on the locking member mounting portion of the lower base body, and the locking member being located on the relatively outer side of the locking edge slot, further away from the column body.

[0011] In some embodiments, the column also has recesses formed on the two side walls and the outer end wall and corresponding to the two side portions and the bridging portion of the metal insert.

[0012] In some embodiments, each of the extension feet has an interference bump that interferes with the recess.

[0013] In some embodiments, the lower body also has two lower fixing grooves extending downward from the corresponding recess of the column, and the extension feet on both sides of the metal insert extend downward to be inserted into the two lower fixing grooves.

[0014] In some embodiments, the inner wall surface of each of the lower fixing grooves is formed with an interference rib that interferes with the corresponding extension foot.

[0015] In some embodiments, each of the extended legs has a hook at its end, and the inner wall of each lower fixing groove has a corresponding hook groove for the hook to engage.

[0016] In some embodiments, the first fastener has a protrusion, and the second fastener is an elastic tab integrally formed from the metal insert and capable of engaging with the protrusion.

[0017] In some embodiments, the second buckle has a spring arm section, a fastening section and a guide section, the fastening section of the second buckle being used to fasten with the protrusion of the first buckle.

[0018] In some embodiments, the locking member further has a locking portion at the top, a protruding portion at the bottom, and a slot below the locking portion. The first latching portion is located on the inner wall surface at the top of the slot, and the second latching portion can extend into the slot and engage with the first latching portion.

[0019] Therefore, in some embodiments, the snap-fit ​​connector of the present invention includes an insulating body, a locking member, and a metal insert. The insulating body has a snap-fit ​​slot extending along a length direction and at least one tower-like structure located at at least one end of the snap-fit ​​slot. The tower-like structure has a column and a guide groove defined by the column and facing the snap-fit ​​slot. The locking member is pivotally mounted on the tower-like structure of the insulating body and is pivotable relative to the insulating body between a locking position relatively close to the guide groove and an unlocking position relatively far from the guide groove. The locking member has a first latching portion. The metal insert is disposed on the tower-like structure of the insulating body and has a second latching portion corresponding to the first latching portion and being elastic. When the locking member is in the locking position, the first latching portion engages with the second latching portion; when the locking member is in the unlocking position, the first latching portion and the second latching portion separate from each other.

[0020] In some embodiments, the first fastener has a protrusion, and the second fastener is an elastic tab integrally formed from the metal insert and capable of engaging with the protrusion.

[0021] In some embodiments, the second buckle has a spring arm section, a fastening section and a guide section, the fastening section of the second buckle being used to fasten with the protrusion of the first buckle.

[0022] In some embodiments, the locking member further has a locking portion at the top, a protruding portion at the bottom, and a slot below the locking portion. The first latching portion is located on the inner wall surface at the top of the slot, and the second latching portion can extend into the slot and engage with the first latching portion.

[0023] The card edge connector of this invention engages with the first snap-fit ​​of the locking member via a resilient second snap-fit ​​portion of the metal insert. Therefore, the locking member does not need to directly interfere with the tower-like structure of the insulating body, avoiding damage to the insulating body. This allows the locking member to be securely positioned at the locking position for firmly locking the electronic card. Furthermore, the second snap-fit ​​portion, integrally constructed from the metal insert and shaped like a resilient snap piece, allows for a smoother locking action with the locking member and maintains a continuous locking capability between them.

[0102] See Figures 1 to 4 A first embodiment of the card edge connector 100 of the present invention is suitable for mounting on a circuit board 200 and for mating with an electronic card 300. The card edge connector 100 includes an insulating body 1, a plurality of mating terminals 2, two locking members 3, and two metal plugs 4.

[0103] The insulating body 1 extends along a left-right direction D1 (the direction indicated by the arrow is right, and the opposite direction is left). The insulating body 1 has a retaining slot 11 formed downward along a vertical direction D2 (the direction indicated by the arrow is right, and the opposite direction is left) and extending along the left-right direction D1 (length direction), a plurality of terminal mounting slots 12 connected to the retaining slot 11, and two tower-shaped structures 13 located at least at the left and right ends of the retaining slot 11. Multiple terminal mounting slots 12 are arranged along the left-right direction D1 and divided into two rows along a front-back direction D3 (the direction indicated by the arrow is front, and the opposite direction is back) located on the front and back sides of the card edge slot 11. Multiple mating terminals 2 are respectively provided in the terminal mounting slots 12 of the insulating body 1. Each mating terminal 2 has a fixing part 21 fixed to the corresponding terminal mounting slot 12, a mating part 22 extending upward from the top of the fixing part 21 and extending into the card edge slot 11, and a tail part 23 extending downward from the bottom of the fixing part 21 and out of the bottom of the insulating body 1. The tail parts 23 of the multiple mating terminals 2 are mechanically and electrically provided to multiple electrical contacts 201 of the circuit board 200 by means of, for example, soldering. When the card edge mating portion 301 at the bottom of the electronic card 300 is inserted into the card edge slot 11, the multiple card edge contacts 301a on the front and rear surfaces of the card edge mating portion 301 will respectively make positive force contact with the mating portions 22 of the multiple mating terminals 2 of the card edge connector 100, so that the card edge connector 100 mates with the electronic card 300. In addition, the insulating body 1 is, for example, fixed to the circuit board 200 by multiple fasteners 5. Each fastener 5 has a connector fixing section 51 located at the top and provided in the mounting slot (not shown) of the card edge connector 100, and a circuit board fixing section 52 located at the bottom and provided in the mounting hole 202 of the circuit board 200. The circuit board fixing section 52 constitutes a pair of pins 521.

[0104] Each of the tower-shaped structures 13 has a lower seat 14 adjacent to the card edge slot 11, a column 15 extending upward from the lower seat 14 and being relatively narrow, and a guide groove 16 formed in the lower seat 14 and the column 15 and facing the card edge slot 11. The guide groove 16 communicates with the card edge slot 11 and can provide a guiding function during the process of inserting the electronic card 300 downward into the card edge slot 11. The lower seat 14 has a locking member mounting portion 141 located on the outer side of the column 15, further away from the locking edge slot 11. For example, the locking member mounting portion 141 is open upwards and communicates with the space between the guide groove 16 and the locking edge slot 11. It has two pivot holes 141a located near the top and spaced apart in the front-rear direction D3. The two locking members 3 are respectively pivotally mounted on the locking member mounting portions 141 of the two tower-shaped structures 13. For example, each locking member 3 has two pivot posts 31 pivotally mounted on the two pivot holes 141a of the corresponding locking member mounting portion 141. Thus, the locking member 3 is pivotally mounted on the lower seat 14 of the tower-shaped structure 13 of the insulating body 1, located on the outer side of the column 15, further away from the locking edge slot 11, and can be in a locking position relatively close to the guide groove 16 relative to the insulating body 1 (see...). Figure 2 ), and an unlocking position relatively far from the guide groove 16 (see Figure 7 It pivots between )

[0105] See Figures 2 to 6The column 15 has two side walls 151 spaced apart in the front-rear direction D3, and an outer end wall 152 connected to the two side walls 151 and located on the opposite outer side. The two side walls 151 and the two outer end walls 152 together define the upper part of the guide groove 16. The lower part of the guide groove 16 is defined by the lower seat 14. The two metal inserts 4 are provided on the columns 15 of the two tower-shaped structures 13 of the insulating body 1, and each metal insert 4 has two side portions 41 spaced apart from each other in the front-rear direction D3 and respectively provided on the side walls 151 of the column 15, and a bridging portion 42 connecting the two side portions 41 and provided on the outer end wall 152 of the column 15. Each side portion 41 of the metal insert 4 has an outer body 410 disposed outside the corresponding side wall 151, and an extension foot 411 connected to the bottom end of the outer body 410 and extending downwardly outside the corresponding side wall 151. The bridging portion 42 is connected between the outer bodies 410 of the two side portions 41 and disposed outside the outer end wall 152 of the column 15. Further, in this first embodiment, the column 15 also has a recess 153 formed outside the two side walls 151 and the outer end wall 152 and correspondingly accommodates the two side portions 41 and the bridging portion 42 of the metal insert 4; the lower seat 14 also has two lower fixing grooves 142 extending downwardly from the recess 153 of the corresponding column 15, and the extension feet 411 of the two side portions 41 of the metal insert 4 extend downwardly to be inserted into the two lower fixing grooves 142. In addition, each of the extension feet 411 has an interference protrusion 411a at its side edge that interferes with the corresponding recess 153, and the inner wall surface of each of the lower fixing grooves 142 is formed with a plurality of interference ribs 142a that extend vertically and interfere with the corresponding extension foot 411 (e.g. Figure 6 (As shown), this makes the metal insert 4 more stable and less prone to loosening.

[0106] It should be noted that, in a variant embodiment, the number of the tower-shaped structure 13 may be only one, and the number of the locking fastener 3 and the metal plug 4 may also be adjusted accordingly to only one each.

[0107] Each of the locking fasteners 3 has a locking portion 32 extending inward from the top, a lever portion 33 extending outward from the top, a protruding portion 34 extending inward from the bottom, a slot 35 extending through the left and right sides below the locking portion 32, and a first latching portion 36 on the inner wall surface at the top of the slot 35. The first latching portion 36 has a protrusion 361 protruding downward from the inner wall surface of the slot 35. It should be noted that the first latching portion 36 may be formed in other embodiments at a location other than the slot 35, and is not limited to this first embodiment. Each metal insert 4 has a second, elastically oriented fastener 43 corresponding to the first fastener 36. The second fastener 43 is an elastic fastener extending outward from the lower edge of the bridging portion 42 of the metal insert 4. The second fastener 43 can extend into the slot 35 and engage with the protrusion 361. The second fastener 43 has a spring arm segment 431 extending outward from the bridging portion 42, a fastening segment 432 extending outward from the spring arm segment 431 and bending upward, and a guide segment 433 extending outward from the fastening segment 432 and inclined downward. The spring arm segment 431 provides elasticity to the fastening segment 432, the fastening segment 432 engages with the protrusion 361 of the first fastener 36, and the guide segment 433 provides guidance during the engagement of the fastening segment 432 with the protrusion 361 of the first fastener 36.

[0108] See Figures 1 to 3 and Figures 7 to 8 When the electronic card 300 is inserted into the card edge slot 11, the side edge of the electronic card 300 inserts into the guide groove 16 and pushes the ejector portion 34 of the locking member 3, causing the locking member 3 to move from the unlocked position to the locked position. When the locking member 3 is in the locked position, as... Figure 2 and Figure 3 As shown, the second latch 43 extends into the slot 35, and the protrusion 361 of the first latch 36 engages with the latching section 432 of the second latch 43, so that the locking member 3 is held in the locking position. In the locking position, the locking part 32 is located above the guide groove 16 and engages with the notch 302 on the side edge of the electronic card 300 in the left-right direction D1, so as to prevent the card edge mating part 301 of the electronic card 300 from exiting the card edge slot 11 and disengaging.

[0109] When the lever part 33 of the locking member 3 is pulled outward by the user, causing the locking member 3 to pivot from the locking position to the unlocking position, as... Figure 7 and Figure 8As shown, the first buckle 36 and the second buckle 43 separate from each other, and the second buckle 43 retracts from the slot 35. During the separation of the first buckle 36 and the second buckle 43, the elastic arm segment 431 bends and deforms downwards, causing the buckling segment 432 of the second buckle 43 to move downwards elastically so that the protrusion 361 of the first buckle 36 passes outwards, thereby allowing the first buckle 36 and the second buckle 43 to smoothly disengage and separate from each other. Conversely, when the first buckle 36 and the second buckle 43 change from a separated state to a buckled state, the elasticity of the elastic arm segment 431 makes the buckling process smoother. When the locking member 3 pivots from the locking position to the unlocking position, the locking part 32 moves outward from above the guide groove 16 and exits from the notch 302 at the side edge of the electronic card 300 in the left-right direction D1. Furthermore, the ejection part 34 pushes the card edge docking part 22 of the electronic card 300 upward, thereby disengaging the electronic card 300 from the card edge connector 100 and making it convenient for the user to remove the electronic card 300.

[0110] See Figures 9 to 12The second embodiment of the card edge connector 100 of the present invention differs from the first embodiment in that each side portion 41 of the metal insert 4 has an inner body 410' disposed on the inner surface of the corresponding side wall 151, and an extension leg 411 connected to the top end of the inner body 410' and disposed on the outer surface of the corresponding side wall 151. The extension leg 411, for example, is formed by bending outward and downward. The bridging portion 42 connects the inner bodies 410' of the two side portions 41 and is disposed on the inner surface of the outer end wall 152. Furthermore, the second latching portion 43 is integrally formed from the upper edge of the bridging portion 42, extending outward over the upper end of the outer end wall 152. Additionally, the metal insert 4 also has a beveled guide surface 44 formed at the connection between the bridging portion 42 and the second latching portion 43, which serves to guide the electronic card 300 during insertion. In addition, in this second embodiment, the recess 153 is formed on the outer surface, inner surface, and upper end of the two side walls 151, and on the inner surface and upper end of the outer end wall 152. Specifically, the recess 153 has an inner recess 153a formed on the inner surface of the outer end wall 152 and the two side walls 151 and correspondingly accommodates the inner body 410' of the two side portions 41 of the metal insert 4 and the recess 153 of the bridging portion 42, and formed on the outer surface of the two side walls 151 and correspondingly accommodates the metal insert 4. The two outer recesses 153b of the extension foot 411 of the two sides 41 of the plug 4, the two first top recesses 153c formed at the upper end of the two side walls 151 and connected between the inner recess 153a and the two outer recesses 153b, correspondingly accommodating the junction of the inner body 410' and the extension foot 411, and the second top recess 153d formed at the upper end of the outer end wall 152 and correspondingly accommodating the junction of the bridging part 42 and the second buckle part 43. The two lower fixing grooves 142 of the lower seat 14 extend downward from the two outer recesses 153b of the recess 153. Figure 11 As shown, the circuit board fixing section 52 forms a through-hole solder pad structure and has an opening 522 to enhance the soldering effect.

[0111] See Figures 13 to 15The third embodiment of the snap-fit ​​connector 100 of the present invention differs from the second embodiment in that each extension leg 411 has a hook portion 411b at its end, and the inner wall surface of each lower fixing groove 142 has a corresponding hook groove portion 142b for the hook portion 411b to engage. The hook portion 411b and the hook groove portion 142b further make the metal plug 4 more stable and less prone to loosening. In addition, the outer end wall 152 has a support protrusion 152a located on the inner side of the downwardly extending portion of the spring arm segment 431 of the second snap-fit ​​43. The support protrusion 152a is used to support the spring arm segment 431 of the second snap-fit ​​43 when the spring arm segment 431 elastically deforms and moves inward toward the support protrusion 152a, thereby increasing the elastic force of the spring arm segment 431 and preventing the spring arm segment 431 from excessively deforming and moving.

[0112] In summary, the card edge connector 100 of the present invention engages with the first latching portion 36 of the locking member 3 via the elastic second latching portion 43 of the metal insert 4. Therefore, the locking member 3 does not need to directly interfere with the tower-shaped structure 13 of the insulating body 1, avoiding damage to the insulating body 1, and thus enabling the locking member 3 to be stably positioned at the locking position to securely lock the electronic card 300. Furthermore, the second latching portion 43, which is integrally constructed with the metal insert 4 and is in the shape of an elastic clip, can more smoothly engage with the locking member 3 and maintain a continuous locking capability between the two.

[0113] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
