Description

Technical Field

[0001] The present invention relates to a self-locking connector unlocking jig, and in particular to a self-locking connector unlocking jig used for a novel self-locking connector with a self-locking function. Background Art

[0002] A board-to-board connector (BTB) is a connector commonly used in electronic devices (such as mobile phones, tablet computers, etc.). Its function is to achieve mechanical and electrical interconnection between the motherboard of the electronic device and various modules (such as display modules, touch modules, camera modules, etc.). The board-to-board connector includes a plug connector and a socket connector that cooperate with each other. The plug connector and the socket connector both include an insulating body extending in the longitudinal direction, conductive terminals fixed to the insulating body, and protective brackets located at both longitudinal ends of the insulating body. The protective brackets are used to improve the strength of each electrical connector. At the same time, the plug connector and the socket connector achieve stable matching between the electrical connectors through the engagement between the protective brackets. However, as board-to-board connectors are used in more and more fields, the engagement between the protective brackets in existing board-to-board connectors can no longer guarantee a good match between the plug connector and the socket connector, which easily leads to problems of loose and unreliable matching between the plug connector and the socket connector. At the same time, existing board-to-board connectors can be separated by using a universal disassembly jig or without a disassembly jig, thereby increasing the problem of the board-to-board connector being disassembled due to misoperation.

[0003] Therefore, it is hoped to provide a new self-locking connector unlocking fixture to overcome the above-mentioned defects. Summary of the Invention

[0004] The object of the present invention is to provide a self-locking connector unlocking jig, which is used on a new self-locking connector with a self-locking part, so that it cannot be separated without a dedicated self-locking connector unlocking jig.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a self-locking connector unlocking jig for separating a new self-locking connector from a docking connector, wherein the new self-locking connector is mounted on a circuit board and includes an insulating body extending longitudinally and locking rods located at both longitudinal ends of the insulating body, wherein the locking rods are provided with a latching portion protruding from the longitudinal end surface of the insulating body and a leg extending vertically from the bottom surface of the insulating body, and the new self-locking connector is latched on the docking connector by the latching portion. The self-locking connector unlocking jig includes a jig body extending in the longitudinal direction, two push blocks located in the jig body and a spring located between the two push blocks. The jig body is provided with a accommodating cavity for accommodating the push blocks, a groove recessed inward from the bottom surface and a through hole connecting the accommodating cavity and the groove. The two push blocks are arranged opposite to each other in the longitudinal direction and are provided with a push block body located in the accommodating cavity and a clamping portion extending downward from the push block body, the clamping portion passes through the through hole and is exposed in the groove; when the new self-locking connector is separated from the docking connector, the circuit board is fixed in the groove, and the clamping portion clamps the leg. At this time, the two push block bodies move relative to each other to drive the locking portion of the locking rod to disengage from the docking connector.

[0006] In a preferred embodiment, the longitudinal length of the through hole is greater than the longitudinal thickness of the clamping portion, so that the two push block bodies can move relative to each other in the longitudinal direction.

[0007] In a preferred embodiment, the push block is provided with an inclined portion protruding outward from the lower end of the push block body, and the accommodating cavity is provided with an inclined wall corresponding to the inclined portion, and the inclined portion is attached to the inclined wall. When the new self-locking connector is separated from the docking connector, the clamping portion clamps the leg and abuts against the bottom surface of the insulating body, at which time the jig body is prompted to move relative to the new self-locking connector, so that the inclined portion slides along the inclined wall, and then the two push block bodies move relative to each other in the longitudinal direction.

[0008] In a preferred embodiment, the jig body is provided with a receiving hole passing through the longitudinal end surface of the jig body, the receiving hole is connected to the accommodating cavity, and the push block is provided with a pressing portion protruding longitudinally from the push block body, and the pressing portion passes through the receiving hole and is exposed on the outside of the jig body.

[0009] In a preferred embodiment, when the new self-locking connector is separated from the docking connector, the clamping portion clamps the leg, and the pressing portion is pressed, causing the two push block bodies to move relative to each other in the longitudinal direction to drive the locking portion of the locking rod to disengage from the docking connector.

[0010] In a preferred embodiment, when the pressing portion is not pressed, the clamping portion abuts against the longitudinal outer wall of the through hole under the action of the elastic force of the spring; when the pressing portion is pressed, the clamping portion overcomes the elastic force of the spring and abuts against the longitudinal inner wall of the through hole.

[0011] In a preferred embodiment, the fixture body includes an outer frame and an upper cover fixed on the outer frame, the outer frame and the upper cover together form the accommodating cavity, and the receiving holes are located on both longitudinal sides of the outer frame.

[0012] In a preferred embodiment, the push block is provided with a clamping hole recessed inwardly from the bottom surface of the clamping portion, and when the novel self-locking connector is separated from the docking connector, the clamping hole is clamped at the free end of the leg.

[0013] In a preferred embodiment, the size of the groove is not smaller than the size of the circuit board, and the jig body is provided with a guide portion extending obliquely from the bottom surface toward the groove and strong glue located on the bottom wall of the groove, the guide portion guides the circuit board into the groove, and the strong glue is used to fix the circuit board to the groove.

[0014] In a preferred embodiment, the circuit board is mounted on the bottom surface of the insulating body and is provided with a notch corresponding to the leg, and the leg extends through the notch. When the new self-locking connector is separated from the docking connector, the clamping portion is received in the notch and clamps the leg.

[0015] Compared to the prior art, the present invention has the following advantages: the self-locking connector unlocking jig comprises a jig body extending longitudinally, two push blocks positioned within the jig body, and a spring positioned between the two push blocks. The jig body is provided with a housing for accommodating the push blocks, a recessed groove recessed inward from the bottom surface, and a through hole connecting the housing and the recess. The two push blocks are longitudinally opposed and comprise a push block body positioned within the housing and a clamping portion extending downward from the push block body. The clamping portion extends through the through hole and is exposed within the recess, thereby forming a dedicated self-locking connector unlocking jig. When the new self-locking connector is separated from the mating connector, the circuit board is retained within the recess, and the clamping portion clamps the leg. At this time, the two push block bodies move relative to each other, driving the latching portion of the locking lever to disengage from the mating connector, thereby enabling the new self-locking connector to be separated from the mating connector only when the dedicated self-locking connector unlocking jig is used. In other words, without the dedicated self-locking connector unlocking jig, the new self-locking connector and the mating connector cannot be separated, thereby preventing the board-to-board connector from being disassembled due to improper operation.

[0032] See also Figures 1 to 6 As shown, a preferred embodiment of the present invention discloses a board-to-board connector comprising a novel self-locking connector 100 and a mating connector 200 that cooperate with each other. The novel self-locking connector 100 is mounted on a circuit board 500 and vertically plugged into the mating connector 200. The novel self-locking connector 100 comprises an insulating body 10 extending longitudinally, conductive terminals 20 retained on the insulating body 10, and protective brackets 30 and self-locking members 40 located at longitudinal ends of the insulating body 10. The insulating body 10 is provided with two longitudinally extending side walls 11 and two end walls 12 connecting the two side walls 11. The two side walls 11 and the two end walls 12 collectively define a receiving space (not numbered) that accommodates the island portion 51 of the mating connector 200.

[0033] The protective bracket 30 is fixed to the end wall 12 and includes a top shielding portion 31 that covers the top surface of the end wall 12, an end shielding portion 32 that bends downward from the longitudinal outer side of the top shielding portion 31, and side shielding portions 33 that bend downward from the lateral sides of the top shielding portion 31. The side shielding portions 33 are fixed to the lateral sides of the end wall 12 to secure the protective bracket 30 to the end wall 12. The end shielding portion 32 partially covers the longitudinal end surface of the end wall 12, and the side shielding portions 33 partially cover the lateral sides of the end wall 12, thereby enhancing the strength of the insulating body 10.

[0034] Combine Figure 3 As shown, the self-locking member 40 is located within the end wall 12 of the insulating body 10. The insulating body 10 is provided with a receiving portion 13 recessed inward from the top surface of the end wall 12 and a through slot 14 extending through the longitudinal end surface of the end wall 12. The through slot 14 is connected to the receiving portion 13. The self-locking member 40 includes a locking rod 41 and an elastic piece 42 located within the receiving portion 13. The top surface shielding portion 31 covers the locking rod 41 and the elastic piece 42.

[0035] The locking lever 41 includes a main body 43 extending vertically and latching portions 44 extending longitudinally outward from either side of the main body 43. The latching portions 44 extend through the through slot 14 and out of the end wall 12. The latching portions 44 are located on either side of the end face shielding portion 32. Furthermore, a gap is formed between the side shielding portion 33 and the end face shielding portion 32, and the latching portions 44 are located within this gap. When the new self-locking connector 100 is plugged into the docking connector 200, the latching portions 44 of the locking lever 41 latch onto the docking connector 200, making it difficult to separate the docking connector 200 from the new self-locking connector 100.

[0036] The insulating body 10 is further provided with a slot (not numbered) extending downward from the bottom wall of the accommodating portion 13 through the bottom surface of the end wall 12. The locking lever 41 is provided with a leg portion 431 extending downward from the main body 43. The leg portion 431 passes through the slot and extends beyond the bottom surface of the insulating body 10. In this embodiment, the bottom surface of the main body 43 abuts the bottom wall of the accommodating portion 13. The longitudinal length of the slot is greater than the longitudinal thickness of the leg portion 431, enabling the locking lever 41 to move longitudinally relative to the end wall 12.

[0037] The elastic piece 42 includes a fixed portion 45 secured to the end wall 12, an extension portion 46 extending from the fixed portion 45 into the accommodating portion 13, and an abutment portion 47 extending and bending from the extension portion 46. The abutment portion 47 abuts against the longitudinal inner side of the main body 43. Specifically, the elastic piece 42 pre-compresses the locking rod 41, ensuring that when the locking rod 41 is engaged with the docking bracket 60, the novel self-locking connector 100 and the docking connector 200 cannot be separated, thereby achieving the self-locking function of the novel self-locking connector 100.

[0038] See also Figures 5 and 6 As shown, the docking connector 200 includes a longitudinally extending docking body 50, docking terminals (not numbered) retained by the docking body 50, and docking brackets 60 located at both longitudinal ends of the docking body 50. The docking body 50 is provided with a longitudinally extending central island 51, two side portions 52 located laterally on either side of the island 51, and two end portions 53 connected to the two side portions 52. The island 51, two side portions 52, and two end portions 53 collectively define a slot 54, within which the island 51 is located. The slot 54 is adapted to accommodate the insertion of the novel self-locking connector 100; that is, when the novel self-locking connector 100 is plugged into the docking connector 200, the insulating body 10 is accommodated within the slot 54.

[0039] The docking bracket 60 is assembled and fixed to the end 53 of the docking body 50 from top to bottom, enhancing the overall strength of the docking connector 200. The docking bracket 60 includes an island reinforcement piece that at least partially covers the island 51, an end reinforcement piece that covers the end 53, and a side reinforcement piece that at least partially covers the side 52. The island reinforcement piece covers the longitudinal ends of the island 51 and extends longitudinally out of the docking body 50. The side reinforcement pieces connect to the transverse ends of the end reinforcement piece, thereby enhancing the inherent strength of the docking connector 200.

[0040] The end reinforcement plate comprises an end top plate portion 61 covering the top surface of the end portion 53, an end inner plate portion 62 extending downwardly from the longitudinal inner side of the end top plate portion 61, an end side plate portion 63 extending downwardly from the longitudinal outer side of the end top plate portion 61, elastic arms 64 extending from the lateral ends of the end side plate portion 63 along the inner wall surface of the side portion 52, and welding legs extending downwardly from the bottom edge of the end side plate portion 63. The end inner plate portion 62 covers the inner wall surface of the end portion 53, and the end side plate portion 63 covers the outer wall surface of the end portion 53, thereby enhancing the strength of the end portion 53 of the docking body 50. The end side plate portion 63 does not extend beyond the outer wall surface of the end portion 53, that is, the end side plate portion 63 enhances the strength of the end portion 53 of the docking body 50 without increasing the overall volume of the docking connector 200.

[0041] The end inner plate portion 62 is provided with latching grooves 621 on both sides thereof for latching the self-locking member 60 of the new self-locking connector 100. When the new self-locking connector 100 is plugged into the docking connector 200, the latching portion 44 of the locking lever 41 is latched into the latching grooves 621 of the docking bracket 60. Furthermore, the latching grooves 621 are located between the end inner plate portion 62 and the elastic arms 64. When the new self-locking connector 100 is plugged into the docking connector 200, the latching portion 44 of the locking lever 41 partially overlaps with the end inner plate portion 62 of the docking bracket 60 in the longitudinal direction, and the elastic arms 64 abut against the side shielding portions 33 on both sides of the protective bracket 30.

[0042] The end portion 53 is provided with a slot 57 extending longitudinally through the end portion 53 and communicating with the slot 54. The elastic arm 64 extends from the outer side of the end portion 53 through the slot 57 and into the slot 54. The elastic arm 64 extends longitudinally within the side region, and a gap is formed between the elastic arm 64 and the inner wall surface of the side portion 52. Specifically, the side portion 52 is provided with a clearance groove 55 recessed inward from its inner wall surface. The clearance groove 55 communicates with the slot 54, and the elastic arm 64 is accommodated within the clearance groove 55, ensuring sufficient movement of the elastic arm 64 during elastic deformation. The elastic arm 64 is provided with a protrusion 641 that protrudes into the slot 54. This provides the elastic arm 64 of the docking bracket 60 with a long moment arm. This ensures stable assembly of the docking connector 200 while resolving the issue of significant yielding of the elastic arm after insertion and removal of the docking connector 200, resulting in stable and reliable contact during use of the docking connector 200.

[0043] The sidewall reinforcement plate includes a side top plate portion 65 that at least partially covers the top surface of the side portion 52, and a side panel portion 66 that bends downwardly from the lateral outer side of the side top plate portion 65. The side panel portion 66 at least partially covers the outer wall of the side portion 52. The side top plate portion 65 is connected to both lateral ends of the end top plate portion 61, so that the side reinforcement plate and the end reinforcement plate form a single unit. The side top plate portion 65 is positioned above the elastic arm 64, thereby protecting the elastic arm 64. The side panel portion 66 does not extend beyond the outer wall of the side portion 52. This means that the side panel portion 66 enhances the strength of the side portion 52 of the docking body 50 without increasing the overall size of the docking connector 200. The docking body 50 is provided with a locking groove 56 on the outer wall of the side portion 52. The side panel portion 66 is received in the locking groove 56 to enhance the stability of the docking bracket 60 fixed to the docking body 50.

[0044] When the new self-locking connector 100 is mated with the docking connector 200, the insulating body 10 is accommodated in the slot 54 of the docking body 50, and the latching portion 44 of the locking rod 41 is pushed by the docking bracket 60 and moves laterally inward until the new self-locking connector 100 is fully plugged into the docking connector 200. The latching portion 44 is latched in the latching groove 621 of the docking bracket 60, making it difficult for the new self-locking connector 100 to be separated from the docking connector 200 without a dedicated self-locking connector unlocking jig.

[0045] See also Figures 7 to 11As shown, a preferred embodiment of the present invention discloses a self-locking connector unlocking jig 300 specifically used to separate a novel self-locking connector 100 from a mating connector 200. The self-locking connector unlocking jig 300 comprises a jig body 70 extending longitudinally, two push blocks 80 positioned within the jig body 70, and a spring 90 positioned between the two push blocks 80. The two push blocks 80 are longitudinally opposed and, under the elastic force of the spring 90, are longitudinally expanded.

[0046] The jig body 70 is provided with an accommodating cavity 71 for accommodating the push block 80, a recess 72 recessed inward from the bottom surface, and a through hole 73 connecting the accommodating cavity 71 and the recess 72. In this embodiment, the size of the recess 72 is not less than the size of the circuit board 500. The jig body 70 is provided with a guide portion extending obliquely from the bottom surface toward the recess 72, and strong glue located on the bottom wall of the recess 72. The guide portion guides the circuit board 500 into the recess 72, and the strong glue is used to secure the circuit board 500 to the recess 72. Thus, when the new self-locking connector 100 is separated from the docking connector 200, the circuit board is secured to the jig body 70, facilitating disassembly of the new self-locking connector 100.

[0047] The push block 80 includes a push block body 81 positioned within the accommodating cavity 71 and a clamping portion 82 extending downward from the push block body 81. The clamping portion 82 extends through the through hole 73 and is exposed within the recess 72, thereby forming a dedicated self-locking connector unlocking jig. The longitudinal length of the through hole 73 is greater than the longitudinal thickness of the clamping portion 82, allowing the two push block bodies 81 to move relative to each other in the longitudinal direction. When the new self-locking connector 100 is separated from the docking connector 200, the circuit board 500 is retained within the recess 72, and the clamping portion 82 clamps the leg 431. At this time, the two push block bodies 81 move relative to each other, driving the latching portion 44 of the locking lever 41 to disengage from the docking connector 200. This allows the new self-locking connector 100 to be separated from the docking connector 200 only with the dedicated self-locking connector unlocking jig. In other words, without the dedicated self-locking connector unlocking jig, the new self-locking connector 100 and docking connector 200 cannot be separated, thereby preventing the board-to-board connector from being disassembled due to improper operation.

[0048] Specifically, the circuit board 500 is mounted on the bottom surface of the insulating body 10 and has a notch corresponding to the leg 431. The leg 431 extends through the notch (not numbered). When the new self-locking connector 100 is separated from the mating connector 200, the clamping portion 82 is received in the notch and clamps the leg 431. Simultaneously, the push block 80 has a clamping hole 821 recessed inward from the bottom surface of the clamping portion 82. When the new self-locking connector 100 is separated from the mating connector 200, the clamping hole 821 clamps the free end of the leg 431.

[0049] In this embodiment, the push block 80 is provided with an inclined portion 83 that protrudes outward from the lower end of the push block body 81. The accommodating cavity 71 is provided with an inclined wall 711 corresponding to the inclined portion 83, and the inclined portion 83 is abutted against the inclined wall 711. When the novel self-locking connector 100 is separated from the docking connector 200, the clamping portion 82 clamps the leg portion 431 and abuts against the bottom surface of the insulating body 10, which in turn causes the jig body 70 to move relative to the novel self-locking connector 100, causing the inclined portion 83 to slide along the inclined wall 711, thereby causing the two push block bodies 81 to move relative to each other in the longitudinal direction, thereby driving the latching portion 44 of the locking lever 41 to disengage from the docking connector 200.

[0050] See also Figures 11 to 16 As shown, the second embodiment of the present invention discloses a self-locking connector unlocking jig 400 specifically used to separate a novel self-locking connector 100 from a mating connector 200. The self-locking connector unlocking jig 400 of the second embodiment is substantially identical to the self-locking connector unlocking jig 300 of the first embodiment. The self-locking connector unlocking jig 400 comprises a jig body 70 extending longitudinally, two push blocks 80 positioned within the jig body 70, and a spring 90 positioned between the two push blocks 80. The two push blocks 80 are longitudinally opposed and, under the elastic force of the spring 90, are longitudinally expanded.

[0051] The jig body 70 includes an outer frame 701, an upper cover 702 secured to the outer frame 701, and a receiving hole 703 extending through the longitudinal end surface of the jig body 70. The outer frame 701 and the upper cover 702 together form the aforementioned receiving cavity 71. The receiving holes 703 are located on both longitudinal sides of the outer frame 701 and communicate with the receiving cavity 71. The push block 80 includes a pressing portion 84 protruding longitudinally from the push block body 81. The pressing portion 84 extends through the receiving hole 703 and is exposed on the outside of the jig body 70.

[0052] When the novel self-locking connector 100 is separated from the docking connector 200, the clamping portion 82 clamps the leg portion 431. At this time, the pressing portion 84 is pressed, causing the two push block bodies 81 to move relative to each other in the longitudinal direction, thereby driving the latching portion 44 of the locking lever 41 to disengage from the docking connector 200. In this embodiment, when the pressing portion 84 is not pressed, the clamping portion 82 abuts against the longitudinal outer wall of the through hole 73 under the elastic force of the spring 90. When the pressing portion 84 is pressed, the clamping portion 82 overcomes the elastic force of the spring 90 and abuts against the longitudinal inner wall of the through hole 73.

[0053] In the present invention, the self-locking connector unlocking jig 300 includes a jig body 70 extending longitudinally, two push blocks 80 positioned within the jig body 70, and a spring 90 positioned between the two push blocks 80. The jig body 70 is provided with a housing 71 for accommodating the push blocks 80, a recess 72 recessed inward from the bottom surface, and a through hole 73 connecting the housing 71 and the recess 72. The two push blocks 80 are longitudinally opposed and each includes a push block body 81 positioned within the housing 71 and a clamping portion 82 extending downward from the push block body 81. The clamping portion 82 extends through the through hole 73 and is exposed within the recess 72, thereby forming a dedicated self-locking connector unlocking jig.

[0054] When the new self-locking connector 100 is separated from the docking connector 200, the circuit board 500 is retained within the recess 72, and the clamping portion 82 clamps the leg 431. At this time, the two push block bodies 81 move relative to each other, driving the latching portion 44 of the locking lever 41 to disengage from the docking connector 200. This allows the new self-locking connector 100 to be separated from the docking connector 200 only with a dedicated self-locking connector unlocking fixture. In other words, without the dedicated self-locking connector unlocking fixture, the new self-locking connector 100 and docking connector 200 cannot be separated, thereby preventing the board-to-board connector from being disassembled due to improper operation.

[0055] In summary, the above are merely preferred embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention should still fall within the scope of the patent of the present invention.
