[ Detailed description ] of the invention
Referring to fig. 1 to 15, a board-to-board electrical connector assembly 1000 according to the present invention includes a first electrical connector 100 mounted on a first circuit board (not shown) and a second electrical connector 200 mounted on a second circuit board (not shown) and engaged with the first electrical connector 100 in an up-down direction. The first electrical connector 100 includes a first insulating body 1 extending in a longitudinal direction, two rows of first conductive terminals 2 arranged in the longitudinal direction and fixed to the first insulating body 1, and a metal housing 3 surrounding the first insulating body 1, preferably, the first conductive terminals 2 are integrally formed on the first insulating body 1. The second electrical connector 200 includes a second insulating body 4 extending in a longitudinal direction, two rows of second conductive terminals 5 fixed to the second insulating body 4 and arranged in the longitudinal direction, and a metal housing 6 surrounding the periphery of the second insulating body 4, and preferably, the second conductive terminals 5 are integrally formed on the second insulating body 4.
Referring to fig. 3 to 7, the first insulating body 1 of the first electrical connector 100 has a first base 11 and a tongue portion 12 extending upward from the first base 11, the circumferential dimension of the first base 11 is larger than the circumferential dimension of the tongue portion 12, and the lateral side surfaces of the tongue portion 12 perpendicular to the longitudinal direction are abutting surfaces 121. The two rows of the first conductive terminals 2 are respectively provided with a first plate-shaped contact surface 21 embedded and fixed on the abutting surfaces 121 on two lateral sides of the tongue 12, and a first welding part 22 extending out of the first base 11 from the lower end of the first plate-shaped contact surface 21. Since the first plate-shaped contact surface 21 is fixed to the tongue 12, the first plate-shaped contact surface 21 does not move relative to the tongue 12, but is fixed to the tongue 12 not particularly by integral fixing, but by interference clamping. The upper ends of the first plate-shaped contact surfaces 21 of each row of the first conductive terminals 2 extend toward the upper surface 122 of the tongue 12 to form a first arc-shaped guide surface 23, and the first conductive terminals 2 are substantially zigzag-shaped. The first arc guiding surface 23 may not only be used to guide the second conductive terminal 5 of the second electrical connector 200 to achieve the abutting connection, so as to avoid the second conductive terminal 5 from wearing the tongue 12, but also increase the binding force between the first conductive terminal 2 and the insulating body 1. It should be noted that, in order to further enhance the bonding force between the first conductive terminal 2 and the first insulating body 1, the first arc-shaped guiding surface 23 may be bent downward to form a bending portion (not shown) further embedded from the upper surface 122 of the tongue portion 12. In the present invention, the first conductive terminal 2 may not be provided with the first arc-shaped guide surface 23 and the bent portion (not shown).
The metal casing 3 is preferably integrally formed and fixed to the first insulating body 1, and the metal casing 3 includes a peripheral wall 31 surrounding the first base 11 and forming an annular slot 30 between the tongues 12, and a pair of spaced bottom plates 32 connected to the lower end of the peripheral wall 31 in the longitudinal direction. Specifically, the peripheral wall 31 includes a pair of side portions 311 extending in the longitudinal direction and a pair of end portions 312 connecting the longitudinal ends of the pair of side portions 311, and the pair of bottom plates 32 connect the lower ends of the longitudinal sides of the pair of side portions 311 to each other. The first soldering portions 22 of the two rows of the first conductive terminals 2 are respectively located inside the pair of side portions 311 and spaced apart from the side portions 311 in the lateral direction. The pair of bottom plates 32 are respectively extended upward to form a pair of plate-shaped embedded parts 321 integrally formed at the two longitudinal ends of the first insulating body 1, and the pair of embedded parts 321 are positioned at the outer sides of the two longitudinal ends of the two rows of first conductive terminals 2. The plate-shaped insertion portion 321 extends upward from the first base 11 into the tongue portion 12, and the plate-shaped insertion portion 321 has a substantially T-shaped structure with a wide upper portion and a narrow lower portion, so that the metal shell 3 can reliably hold the first insulating body 1 by the plate-shaped insertion portion 321. A through-hole 33 is formed between the pair of bottom plates 32 in the longitudinal direction, the through-hole 33 is defined by the pair of bottom plates 32 and the pair of side portions 311, and a portion of the first insulating body 1 located between the pair of plate-shaped insertion portions 321 is provided in the region of the through-hole 33. The lower ends of the pair of side portions 311 extend downward in the area corresponding to the first soldering portion 22 to form soldering pins 3111 soldered to a first circuit board (not shown), and the lower ends of the pair of side portions 311 are recessed upward in the area corresponding to the first soldering portion 22 to form an inspection window 3112 for viewing the first soldering portion 22 laterally inward.
Each of the end portions 312 includes a first half-end portion 3121 connected to one of the side portions 311 and a second half-end portion 3122 connected to the other of the side portions 311, the free end of the first half-end portion 3121 protrudes to form a protruding portion 31211, the free end of the second half-end portion 3122 is concavely provided with a groove portion 31221, and the protruding portion 31211 is engaged with the groove portion 31221 so that the first half-end portion 3121 and the second half-end portion 3122 together constitute the end portion 312. Preferably, the profile of the protruding portion 31211 and the recessed portion 31221 is substantially spherical. The bottom plate 32 is formed with a pair of limiting portions 322 extending longitudinally and outwardly below the end 312, the first half-end 3121 and the second half-end 3122 are respectively extended downwardly to form an extending portion 313 between the pair of limiting portions 322, and the pair of limiting portions 322 are used for blocking the extending portion 313 and preventing the first half-end 3121 and the second half-end 3122 from being separated from each other. In the present invention, at least one of the bottom plate 32, the extension portion 313 and the restriction portion 322 may serve the purpose of soldering the metal case 3 to the first circuit board (not shown). In addition, for reliable bonding between the first half-end 3121 and the second half-end 3122, a welding process may be performed at the seam of both. It should be noted that, in the present invention, the metal casing 3 is formed by bending a single plate, whereas the metal casing 3 is unfolded to form a single plate member, so that the metal casing 3 has a high structural strength and is convenient for manufacturing.
As shown in fig. 8 to 15, the second insulating body 4 of the second electrical connector 200 has a second base 41, a pair of side walls 42 extending in the longitudinal direction formed to extend upward from the second base 41, and a pair of end walls 43 connecting both ends of the side walls 42 in the longitudinal direction. The pair of side walls 42 and the pair of end walls 43 enclose a slot 44, and the two rows of second conductive terminals 5 respectively have a second plate-shaped contact surface 51 embedded in the inner surfaces 420 of the pair of side walls 42, and a second soldering portion 52 extending laterally outward from the lower ends of the second plate-shaped contact surfaces 51 out of the second base 41. since the second plate-like contact surface 51 is fixed to the side wall 42, the second plate-like contact surface 51 does not move relative to the side wall 42, and the fixation is not particularly limited to the fixation by integral molding, but may be fixed to the side wall 42 by interference clamping. The upper ends of the second plate-shaped contact surfaces 51 of each row of the second conductive terminals 5 further extend toward the upper surface of the side wall 42 to form a second arc-shaped guide surface 53, the second conductive terminals 5 are substantially in a figure コ shape, and the second arc-shaped guide surface 53 not only can be used for being matched with the first arc-shaped guide surface 23 of the first conductive terminal 2 to serve as a guide for each other, but also can increase the binding force of the second conductive terminals 5 and the second insulating body 4. Of course, in order to further enhance the bonding force between the second conductive terminal 5 and the second insulating body 4, the second arc-shaped guiding surface 53 may also be bent downward to form a bent portion (not shown). In the present invention, the second conductive terminal 5 may not be provided with the second arc-shaped guide surface 53 and the bent portion (not shown). When the first electrical connector 100 and the second electrical connector 200 are mated with each other, the tongue plate 12 is inserted into the slot 44, the pair of side walls 42 and the pair of end walls 43 are inserted into the annular slot 30, and the first conductive terminal 2 is mated with the second conductive terminal 5. in the present invention, the path from the first soldering portion 22 of the first conductive terminal 2 to the first plate-shaped contact surface 21 is shorter, and the path from the second soldering portion 52 of the second conductive terminal 5 to the second plate-shaped contact surface 51 is shorter, so that the first conductive terminal 2 and the second conductive terminal 5 are electrically connected only by the contact between the first plate-shaped contact surface 21 and the second plate-shaped contact surface 51, so that the conducting path between the first conductive terminal 2 of the first electrical connector 100 and the second conductive terminal 5 of the second electrical connector 200 is shorter, thereby not only reducing the high-frequency insertion loss of the two electrical connectors, but also reducing the volume of the two electrical connectors, and further reducing the area occupied by the two electrical connectors by two circuit boards (not shown). In consideration of the problem of reliability of the butt joint between the first plate-like contact surface 21 and the second plate-like contact surface 51, one of the first plate-like contact surface 21 and the second plate-like contact surface 51 is projected with a contact convex portion 511, and the other is recessed with a contact concave portion 211 into which the contact convex portion 511 is engaged. The upper end of the contact protrusion 511 is formed with a guide slope 5111, and the contact recess 211 into which the contact protrusion 511 is engaged can be facilitated by the provision of the guide slope 5111. In the present invention, the first conductive terminal 2 and the second conductive terminal 5 are formed by punching, the second plate-shaped contact surface 51 of the second conductive terminal protrudes to form the contact protrusion 511, and the contact protrusion 511 is formed by punching from the opposite side of the second plate-shaped contact surface 51 toward the second plate-shaped contact surface 51, so that the second plate-shaped contact surface 51 is concavely formed with a groove 512 on the opposite side of the contact protrusion 511. correspondingly, the inner surface 420 of the side wall 42 has an embedded protrusion 4201 embedded in the recess 512 when molded at the position corresponding to the recess 512, so that the second conductive terminal 5 can be reliably bonded to the side wall of the second insulating body 4.
The outer side surfaces 421 of the pair of side walls 42 of the second electrical connector 200 are concavely formed in the arrangement region of the second conductive terminals 5 to form a receiving space 4211 concavely formed to penetrate the upper and lower surfaces of the side walls 42, and the second soldering portion 52 of the second conductive terminals 5 is disposed in the receiving space 4211 when viewed from the upper and lower directions. Compared with the second welding portion 52 extending out of the side wall, the second welding portion 52 is disposed in the accommodating space 4211 concavely disposed in the side wall 42, so that the overall length of the second conductive terminal 5 can be effectively reduced, and the conduction path between the second conductive terminal 5 and the first conductive terminal 2 can be further reduced. The metal housing 6 of the second electrical connector 200 is integrally formed with the second insulating body 4, the metal housing 6 includes a pair of plate-shaped side walls 61 respectively fitted and fixed to the outer side surfaces 421 of the pair of side walls 42, the pair of plate-shaped side walls 61 includes a baffle portion 611 shielding the accommodating space 4211 and side plate portions 612 extending from both longitudinal sides of the baffle portion 611 and fitted and fixed to the outer side surfaces 421 of the side walls 42, and the second welding portion 52 is disposed in the accommodating space 4211 and located inside the baffle portion 611 of the plate-shaped side walls 61 when viewed from the top and bottom. When the second electrical connector 200 is mated with the first electrical connector 100, the pair of side portions 311 of the metal shell 3 are located outside the plate-shaped side wall 61 and abut against the plate-shaped side wall 61. A top plate 62 fitted to the upper surface 431 of the end wall 43 is connected between the side plate portions 612 on both sides in the longitudinal direction of the pair of plate-like side walls 61, and the top plate 62 extends downward to form the end plate portion 63 fitted to the end face 432 of the end wall 43. When the first electrical connector 100 and the second electrical connector 200 are mated with each other, the metal shell 3 is in cladding contact with the outer side of the metal housing 6. The connection between the pair of top plates 62 and the side plate 612 forms an arc guide 64, the connection between the end plate 63 and the top plate 62 forms an arc guide 65, and the upper edge of the outer surface of the baffle 611 forms a guide surface 6111, so that when the first electrical connector 100 and the second electrical connector 200 are abutted against each other, the metal shell 3 can be easily covered and finally abutted against the outer side of the metal housing 6 through the guidance between the arc guides 64 and 65 and the guide surface 6111. In addition, the upper edges of the side 311 and the inner surface of the end 312 of the metal shell 3 of the first electrical connector 100 are also provided with a guiding surface 314 for guiding the insertion of the second electrical connector.
In order to reliably solder the second electrical connector 200 to a second circuit board (not shown), the side plate portion 612 is torn and formed with a first solder leg 6121 embedded in the end wall 43 and extending downward from the end wall 43, the end plate portion 63 is torn and formed with a second solder leg 631 embedded in the end wall 43 and extending downward from the end wall 43, and the lower end of the baffle portion 611 is extended outward to form a third solder leg 6112. In order to reliably combine the metal shell 3 and the metal shell 6, at least one of the plate-shaped side wall 61 and the baffle 611 of the metal shell 6 is protruded with a clamping point 64, and at least one of the side 311 and the end 312 of the metal shell 3 is concavely provided with a clamping groove 315 matched with the clamping point 64. The lower end of the baffle 611 is concavely provided with a viewing window 6113 for viewing the second welding portion 52 laterally inward. In addition, the side portion 311 of the metal shell 3 of the first electrical connector 100 is recessed with a notch 3113 corresponding to the third solder leg 6112 of the metal shell 6 of the second electrical connector, and when the two electrical connectors are mated, the third solder leg 6112 is received in the notch 3113 to limit the relative movement of the electrical connectors in the longitudinal direction.
