Description

Technical Field

[0001] This utility model relates to the field of board-to-board connector technology, and in particular to a socket connector for stable connection. Background Technology

[0002] Electrical connectors enable electrical connections and signal transmission between devices, components, and systems, and are essential components for forming a complete system. Currently, electrical connectors are widely used in various electronic products. Board-to-board connectors (BTB) are used to electrically connect two parallel circuit boards, typically consisting of mating plug and socket connectors. The plug connector includes a plug body, plug terminals held on the plug body, and plug protective supports located at both longitudinal ends of the plug body. The socket connector includes a socket body, socket terminals held on the socket body, and socket protective supports located at both longitudinal ends of the socket body. However, these protective supports are often formed using metal stamping, bending, and partial drawing methods, resulting in low protective strength and susceptibility to deformation and damage during mating. Furthermore, when the plug and socket connectors are mated, the connection is typically achieved through a single elastic contact on the socket protective support, leading to poor current flow in the board-to-board connector.

[0003] Therefore, it is hoped that a new socket connector can be proposed to overcome the above-mentioned defects. Utility Model Content

[0023] Please see Figures 1 to 7 As shown, a preferred embodiment of the present invention discloses a board-to-board connector, which includes a socket connector 100 and a plug connector 200 that mate with each other. The socket connector 100 is used for mounting on a circuit board and includes a socket body 10 extending longitudinally, a plurality of socket terminals 20 fixed on the socket body 10, and socket protection brackets 30 located at both ends of the socket body 10 in the longitudinal direction.

[0024] Please see Figure 2 As shown, the socket body 10 has a central island portion 11 extending longitudinally, two side portions 12 located on both sides of the island portion 11 laterally, and two end portions 13 connected to the two side portions 12. The island portion 11, the two side portions 12, and the two end portions 13 together define a socket slot 14, that is, the island portion 11 is located within the socket slot 14, and the socket slot 14 allows the insertion of a plug connector 200.

[0025] Combination Figure 3 and Figure 4As shown, the socket protection bracket 30 is fixed to the end 13 of the socket body 11 and has an upwardly drawn outer socket shielding portion 31 and an inner socket shielding portion 32 drawn downward from the top surface of the outer socket shielding portion 31. The outer socket shielding portion 31 covers the outer wall surface of the end 13 and at least part of the side portion 12, and the inner socket shielding portion 32 covers the inner wall surface of the side portion 12 and the end 13. Thus, the outer socket shielding portion 31 enhances the overall strength of the socket body 10, thereby preventing scratches on the socket body 10, and the inner socket shielding portion 32 enhances the resistance to misalignment and deformation.

[0026] Specifically, the socket outer shielding portion 31 includes an end top plate portion 41 covering the top surface of the end portion 13, an end outer plate portion 42 extending downward from the longitudinal outer side of the end top plate portion 41, a side top plate portion 43 covering the top surface of the side portion 12, and a side outer plate portion 44 extending downward from the lateral outer side of the side top plate portion 43. The side top plate portion 43 is connected to both lateral ends of the end top plate portion 41, the end outer plate portion 42 covers the outer wall surface of the end portion 13, and the side outer plate portion 44 at least partially covers the outer wall surface of the side portion 12 and is connected to the end outer plate portion 42; thus, the end top plate portion 41, the side top plate portion 43, the end outer plate portion 42, and the side outer plate portion 44 are seamlessly connected to each other.

[0027] Meanwhile, the outer end plate 42 of the socket outer shielding part 31 is provided with an end welding piece 421 located at the bottom edge, and the side outer plate 44 does not extend beyond the lateral outer wall of the side part 12 and is provided with a side welding piece 441 extending laterally outward from the bottom edge. The side welding piece 441 is connected to the end welding piece 421 and welded to the same solder pad on the circuit board.

[0028] The inner shielding portion 32 of the socket includes an inner end plate portion 45 extending downward from the longitudinal inner side of the top end plate portion 41, a side inner plate portion 46 extending downward from the transverse inner side of the top side plate portion 43, and a bottom plate portion 47 located at the bottom of the socket slot 14. The inner end plate portion 45 covers the inner wall surface of the end portion 13, and the side inner plate portion 46 covers part of the inner wall surface of the side portion 12 and is connected to the inner end plate portion 45. The bottom plate portion 47 is connected to the bottom of the inner end plate portion 45 and the side inner plate portion 46, and the inner end plate portion 45, the side inner plate portion 46, and the bottom plate portion 47 form a seamless connection with each other; thereby, the socket protection bracket 30 forms an integral metal pull-out member, and the socket protection bracket 30 adopts a stretch-and-reverse stretch structure to improve the overall strength of the socket connector 100.

[0029] The socket protection bracket 30 also includes an island reinforcement 33 extending upward from the longitudinal inner side of the base plate 47 and two elastic arms 34, the two elastic arms 34 being located on the lateral sides of the island reinforcement 33. The island reinforcement 33 covers the longitudinal sides of the island 11 to achieve metal protection for the island 11; specifically, the island reinforcement 33 includes an island shielding 331 extending upward from the longitudinal inner side of the base plate 47 and an embedded part 332 extending downward from the top of the island shielding 331. The island shielding 331 covers the longitudinal outer wall of the island 11 and does not extend beyond the top and sides of the island 11, the embedded part 332 being embedded in the island 11 to improve the overall strength of the island 11.

[0030] The elastic arm 34 extends laterally from the longitudinal inner side of the base plate 47 to the side portion 12. The side portion 12 is provided with a recessed groove 15 that is recessed inward from the inner wall surface. The recessed groove 15 is located on the longitudinal inner side of the outer shielding portion 31 and the inner shielding portion 32 of the socket and communicates with the socket slot 14. The elastic arm 34 is received in the recessed groove 15 and is used to fasten to the side shielding portion 83 of the plug protection bracket 80 of the plug connector 200 to meet the high current carrying requirement of 5A.

[0031] Meanwhile, the island reinforcement 33 and the elastic arm 34 do not overlap with the outer shielding part 31 and the inner shielding part 32 of the socket in the longitudinal direction. Furthermore, the elastic arm 34 is located longitudinally inside the end inner plate part 45 and the side inner plate part 46, and the projections of the side inner plate part 46 and the elastic arm 34 overlap with each other in the transverse direction.

[0032] Please see Figures 5 to 7 As shown, the plug connector 200 includes a longitudinally elongated plug body 60, a plurality of plug terminals 70 fixed on the plug body 60, and plug protection brackets 80 located at both longitudinal ends of the plug body 60. The plug body 60 has two longitudinally extending side walls 61 and two end walls 62 connected to the two side walls 61. The plug terminals 70 are fixed on the side walls 61, and the plug protection brackets 80 are fixed on the end walls 62.

[0033] The plug protection bracket 80 has an upwardly drawn outer plug shielding portion 801 and an inner plug shielding portion 802 drawn downward from the top surface of the outer plug shielding portion 801. The outer plug shielding portion 801 covers the outer wall surfaces of the side wall 61 and the end wall 62, and the inner plug shielding portion 802 covers the inner wall surfaces of the side wall 61 and the end wall 62, thereby improving the strength of the plug body 60 and preventing damage to the plug body 60 when the plug connector 200 is inserted or removed. At the same time, the plug protection bracket 80 is integrally drawn, which enhances the resistance to misalignment and deformation while providing higher guiding strength.

[0034] Specifically, the plug outer shielding portion 801 includes a top shielding portion 81 covering the end wall 62 and at least part of the side wall 61, an outer wall shielding portion 82 extending downward from the longitudinal outer side of the top shielding portion 81, and side shielding portions 83 extending downward from both transverse sides of the top shielding portion 81. The outer wall shielding portion 82 covers the longitudinal outer wall surface of the end wall 62, and the side shielding portion 83 at least partially covers the transverse outer wall surface of the side wall 61 and is connected to the outer wall shielding portion 82. Thus, the top shielding portion 81, the side shielding portion 83, and the outer wall shielding portion 82 form a seamless connection with each other, and the plug outer shielding portion 801 enhances the overall strength, thereby preventing scratches on the plug body 60.

[0035] The sidewall 61 and endwall 62 form a plug slot 63. The plug inner shielding part 802 is provided with an inner wall shielding part 84 that is drawn downward from the inside of the top shielding part 81. The inner wall shielding part 84 is U-shaped and covers the inner wall surface of the endwall 62 and part of the sidewall 61. Therefore, the plug inner shielding part 802 enhances the resistance to misalignment and deformation while providing higher guiding strength.

[0036] When the socket connector 100 and the plug connector 200 are plugged in, the outer shielding part 801 of the plug contacts the inner shielding part 32 of the socket, and the inner shielding part 802 of the plug contacts the reinforcing part. Therefore, both the socket protection bracket 30 and the plug protection bracket 80 adopt a fully pull-out structure, which has high overall strength and is not prone to deformation when misaligned, thereby preventing the risk of short circuit.

[0037] Specifically, when the socket connector 100 and the plug connector 200 are plugged in, the outer wall shielding portion 82 of the plug protection bracket 80 contacts the end inner plate portion 45 of the socket protection bracket 30, and / or the side shielding portion 83 of the plug protection bracket 80 contacts the side inner plate portion 46 of the socket protection bracket 30, the top surface shielding portion 81 of the plug protection bracket 80 contacts the bottom plate portion 47 of the socket protection bracket 30, and the plug inner shielding portion 802 of the plug protection bracket 80 covers the island reinforcement portion 33; at the same time, the elastic arm 34 of the socket protection bracket 30 abuts against the side shielding portion 83 of the plug protection bracket 80.

[0038] In this invention, the socket protection bracket 30 is provided with an upwardly drawn outer socket shielding part 31 and an inner socket shielding part 32 drawn downward from the top surface of the outer socket shielding part 31. The outer socket shielding part 31 covers the outer wall surface of the end portion 13 and at least part of the side portion 12, and the inner socket shielding part 32 covers the inner wall surface of the side portion 12 and the end portion 13 and is provided with a base plate part 47 located at the bottom of the socket slot 14. The socket protection bracket 30 adopts a stretching and reverse stretching structure to improve the overall strength. The socket protection bracket 30 is provided with an island reinforcement part 33 that bends upward from the longitudinal inner side of the base plate part 47 and two elastic arms 34. The island reinforcement part 33 covers the longitudinal sides of the island portion 11 to achieve metal protection of the island portion 11; the two elastic arms 34 are located on the lateral sides of the island reinforcement part 33 to meet the high current carrying requirement of 5A.

[0039] In summary, the above are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model should still fall within the scope of the present utility model patent.
