Description

Stacked connector assembly

[ field of technology ]

The present utility model relates to a stacked connector assembly, and more particularly, to a stacked connector assembly that can simplify the manufacturing process and be miniaturized.

[ background Art ]

A conventional electrical connector, such as the TWM242873 of taiwan patent, comprises a combined electrical connector formed by stacking a first electrical connector 3 and a second electrical connector 4 one above the other, the first electrical connector 3 having a plurality of conductive terminals 32, a circuit board 31, each of the conductive terminals 32 having a solder tail 313 passing through a hole of the circuit board 31 and soldered thereto, the conductive terminals 32 having a horizontal portion below the circuit board 31 and having one end connected to the solder tail 313 and the other end connected to a bend 322, a contact portion connected to the bend 322, the contact portion being above the circuit board 31 and adapted to interface with an interface element, a terminal module 34 being below the circuit board and having a plurality of long terminals 341 and a plurality of short terminals 342 soldered to the circuit board 31 by way of solder tails 340, the second electrical connector 4 being assembled below the circuit board 31 and the conductive terminals 32 and adapted to interface with another interface element.

However, since the plurality of conductive terminals 32 are not provided with the insulating blocks for fixing the conductive terminals 32, when the plurality of conductive terminals 32 are soldered to the circuit board 31, the plurality of conductive terminals 32 need to be fixed one by one in an additional jig, and then the plurality of conductive terminals 32 fixed by the jig are aligned and soldered to the holes of the circuit board 31, which makes the assembly process complicated and is not conducive to mass production.

In order to solve the above-mentioned problems, it is generally conceivable that an injection molding block is injected into the horizontal portion of the plurality of conductive terminals 32 to fix the plurality of conductive terminals 32, but the injection molding block is injected into the carrier 343 in addition to the horizontal portion of the plurality of conductive terminals 32, which not only increases the manufacturing process but also increases the manufacturing cost of the combined electrical connector, and further, since the horizontal portion of the conductive terminals 32 is located below the circuit board 31, the newly added injection molding block is located below the circuit board, so that the injection molding block occupies a part of the space downwards, so that the first electrical connector 3 cannot be directly assembled into the existing body 2, and the height of the existing body 2 must be increased in the up-down direction to allow the newly added injection molding block and the terminal module to be assembled, which is disadvantageous for miniaturization of the combined electrical connector.

Therefore, there is a need to design a stacking connector assembly to solve the above-mentioned technical problems.

The bottom surface of the receiving groove 3111 may be located below the horizontal section 3361, so as to limit the downward displacement of the horizontal section 3361, and further limit the downward displacement of the second terminal 33 and limit the horizontal section 3361 to the receiving groove 3111, so as to further improve the positional accuracy of the welding portion 336. The height of the upper surface of the main body 311 protruding upward from the first solder leg 322 in the up-down direction is substantially equal to the height of the upper surface of the main body 311 protruding upward from the solder 336, so that the solder cannot be stably soldered to the hole 341 of the interposer 34 due to the fact that the height of either the first solder leg 322 or the solder 336 protruding from the upper surface of the main body 311 is too high, which results in that the solder is diluted during reflow soldering with the interposer 34.

As shown in fig. 1, 4, 5, 7 and 8, the adapter plate 34 is located above the main body 311, and the adapter plate 34 is provided with a plurality of holes 341 penetrating up and down, and the holes 341 are used for the first solder pins 322, the soldering portion 336 and the winding terminal 351 to pass through for soldering.

Each of the vertical slots 162 is located directly above a corresponding one of the indicator lights 36. The two light guide posts 37 are respectively accommodated in the two light blocking slots 16, so that the light signals of the indicator light 36 can be transmitted to the front surface of the plastic body 1 through the corresponding light guide posts 37, and the side wall 1621 on one side of the vertical slot 162 is positioned right above the shielding plate 3124, so that the side wall 1621 can not only block the light signals transmitted by the light guide posts 37, but also further block the indicator light 36 and the limiting part 331, thereby avoiding electric spark generated between the indicator light 36 and the limiting part 331 due to excessive voltage when the indicator light 36 and the second terminal 33 pass through the current.

(3) The two indicator lamps 36 are respectively located at the left and right sides of the limiting block 312 along the left and right directions, so that the overall length of the stacked connector assembly 1000 in the front and rear directions can be shortened relative to the situation that the indicator lamps 36 are located at the rear of the adapter plate 34, which is beneficial to miniaturization of the stacked connector assembly 1000, and the shielding plate 3124 is used for isolating the indicator lamps 36 and the limiting part 331 along the left and right directions, so that electric sparks generated by overlarge voltage of the current in the process of passing the current between the indicator lamps 36 and the second terminal 33 are avoided.
