The connection portion of the first connection portion 333 and the second connection portion 334 extends out of the metal shell 31 and is accommodated in the through hole 11 of the circuit board 1. The second connecting portion 334 is further divided into two separated portions 3341 such that one separated portion 3341 corresponds to one base portion 321, and the free end of the separated portion 3341 is bent toward the base portion 321. The fixing portion 331 extends two blocking portions 332 toward the two separating portions 3341.
As shown in fig. 2 and fig. 3, in the present embodiment, the elastic pushing element 33, the locking element 32 and the metal housing 31 are separated, but in other embodiments, the elastic pushing element 33 may be an elastic body made of plastic material, such as a silicon rubber body, which is compressed to generate an elastic force; the fastening element 32 may also be formed separately, and the elastic pushing element 33 and the metal shell 31 may be formed in one piece; the metal shell 31 may also be formed separately, and the elastic pushing element 33 and the fastening element 32 may be formed in one piece.
As shown in fig. 1, 2 and 4, the second side 42 of the electronic card 4 is held by the holding device 3. In the Z direction, the second side edge 42 is disposed above the first position-limiting portion 310, and the first position-limiting portion 310 is used for stopping the second side edge 42 from moving downward. In the Y direction, the sidewall 313 is located at the right side of the second side edge 42 and enters the groove 421. The sidewall 313 is used to limit the second side edge 42 from moving back and forth along the X direction and moving right along the Y direction.
As shown in fig. 2, 3 and 4, when the locking element 32 is located at the locking position, the base 321 is located in the first receiving hole 314 and the second receiving hole 315, and the elastic pushing element 33 is located in the first receiving hole 314. When viewed in the Y direction, the locking portion 323 exceeds the sidewall 313 and abuts the second side 42 downward, so as to stop the second side 42 from moving upward. The abutting portion 325 is longer than the fastening portion 323 in the Y direction, and in the Z direction, the abutting portion 325 abuts against the abutting surface 3101 upward, and since the second side edge 42 is supported below the fastening portion 323 and pushes the fastening portion 323 upward, even if the fastening portion 323 moves upward in the Z direction, the abutting portion 325 abuts against the abutting surface 3101 more tightly as the fastening portion 323 moves upward.
As shown in fig. 2, 3 and 4, the free end of the separating portion 3341 abuts against the base 321, and the elastic pushing member 33 provides a pre-pressure for the locking member 32 to move leftward in the Y direction by its own elasticity, so as to ensure that the locking portion 323 can stably lock the second side edge 42.
As shown in fig. 2, 4 and 5, if the electronic card 4 is to be taken out, the operation portion 322 is pulled rightwards along the Y direction, so that the locking member 32 slides rightwards along the Y direction until the locking member is separated from the second side 42, the locking member 32 is located at the unlocking position, and the locking of the second side 42 by the locking portion 323 can be released. The base 321 is separated from the second receiving hole 315 and completely located in the first receiving hole 314, and the elastic pushing element 33 is always located in the first receiving hole 314.
As shown in fig. 2, 3 and 5, while the locking element 32 slides rightward along the Y direction, the base 321 pushes the second connecting portion 334 to move rightward and is located in the recessed portion 326, the left side of the second connecting portion 334 abuts against the abutting portion, the blocking portion 332 abuts against the right side of the second connecting portion 334, the recessed portion 326 and the blocking portion 332 limit the second connecting portion 334 together, and the blocking portion 332 can block the second connecting portion 334 and the locking element 32 from moving rightward excessively along the Y direction. In this embodiment, the left side of the base 321 does not abut against the side wall 313, but the left side of the base 321 may abut against the side wall 313 in other embodiments.
In summary, the connector assembly 100 and the latching device 3 thereof of the present invention have the following advantages:
(1) in the Z direction, the second side edge 42 is located on the first position-limiting portion 310, the first position-limiting portion 310 is used to stop the second side edge 42 from moving downward, and the sidewall 313 is located in the groove 421 for accommodating the second side edge 42 and is used to limit the second side edge 42 from moving forward and backward in the X direction and moving rightward in the Y direction. The fastening portion 323 abuts against the second side 42 downward in the Z direction to stop the second side 42 from moving upward.
(2) The holding portion 325 is longer than the locking portion 323 in the Y direction, the holding portion 325 is closer to the electrical connector 2, and the holding portion 325 always abuts against the holding surface 3101 in the Z direction, so that when the operating portion 322 is pulled, the whole locking member 32 can be driven to slide smoothly between the locking position and the unlocking position. When the fastener 32 is located at the locking position, the fastening portion 323 locks the second side edge 42, and since the second side edge 42 is supported below the fastening portion 323 and pushes up the fastening portion 323 in the Z direction, the abutting portion 325 is more tightly abutted against the abutting surface 3101 as the fastening portion 323 moves upward, so as to prevent the fastener 32 from moving upward, and the fastening portion 323 more firmly locks the second side edge 42.
(3) The elastic pushing element 33 abuts against the base 321, and the elastic pushing element 33 provides a pre-pressure to the fastening element 32 by its own elasticity, so as to help the fastening portion 323 return to the original position.
(4) The connection part of the operation part 322 and the base part 321 is a rounded corner, and in the X direction, the thickness of the operation part 322 is greater than that of the fastening part 323, which is beneficial to increase the contact area between the user and the operation part 322, and the operation part 322 is pulled more conveniently and safely.
The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all technical changes that can be made by applying the present specification and drawings are included in the scope of the present invention.
